Product Description

Working Principle:
During the equipment is in operation, materials are evenly fed through feed inlet. Meanwhile, the bucket fixed on the conveyor belt (chain) is driven by the active drum to lift the materials along with the belt (chain) until it reaches the top of the active drum. At this point, the bucket starts to flip over and then under the action of centrifugal force or gravity, it discharges the materials from discharge port and sends them to the next process. The bucket elevator is suitable for the scenario that needs to lift the materials from a low place to a high place with the lifting height of up to 40 meters. In general, the bucket elevator is equipped with casings to prevent the dust from blowing.
Installation Steps for Bucket Elevators:
1. Bucket elevators must be installed firmly on a solid concrete foundation. The surface of the concrete foundation must be flat and horizontal to ensure the verticality of the bucket elevator after installation.
For taller bucket elevators, the appropriate positions on their middle and upper casings should be fixed with the adjacent buildings (such as silos workshops, etc.) to enhance their stability. When installation, install the lower components and fix the anchor bolts first, and then install the middle casting, and finally install the upper casing. After the casings are installed successfully, the verticality needs to be corrected. Check the verticality with thin steel wires and hanging strings,and the error should be less than 10mm. The upper and lower axes should be parallel, and their centerlines should be in the same plane.
For the installation of bucket elevators with lower height, the upper, middle and lower casings can be connected and corrected on the ground plane and then be hoisted as a whole and vertically fixed on the concrete foundation.
2. After the casings are installed, install the chain and the hoppers. The U-shaped bolts that connecting the hoppers are both the connectors of the chain and the fasteners of the hoppers. The nuts of the U-shaped bolts must be tightened and locked up.
3. After the chain and the hoppers are installed, they should be tensioned appropriately.
4. Add an appropriate amount of engine oil and grease to the reducer and the bearing housing. The reducer is lubricated with the industrial gear oil while the bearing housing is lubricated with calcium-based or sodium-based grease.
5. After the installation, a no-load test run should be conducted immediately. When running idle, it should be noted that it must not be reversed and there should be no bumps or knocks. The idle running should not be less than 2 hours. There should be no overheating. The temperature rise of the bearing should not exceed 250ºC, and that of the reducer should not exceed 300ºC. After 2 hours' idle running, if everything is normal, a load test running can be conducted. Feeding should be uniform during a load test running to prevent excessive feeding and blocking the lower part and causing "stalling".
Maintenance Precautions:
1. Bucket elevator should be started with no-load condition. Therefore, all the materials in the hoppers should be drained completely every operation and then the machine can only be stopped.
2. Reverse is not permitted. Reverse probably will result in the chain to derailment, and it is very troublesome to eliminate the derailment fault.
3. Uniform feeding. It is prohibited to increase the feeding amount abruptly. Feeding amount can't exceed the conveying capacity of the hoist otherwise, it is easy to cause the material at the bottom to accumulate, and in severe cases, a "stalling" accident may occur.
4. Replenish the lubricating oil in a timely and appropriate manner.
5. Replace the worn or damaged chain and hoppers in time.
Safety Specification:
1. The maintenance and management of the bucket elevator should be conducted by designated personnel and the keys to the power switch box are also managed by designated personnel.
2. The hoist should have a sign marked the maximum load capacity. During lifting and lowering, the weight can't exceed the maximum load by 1 ton.
3. The hoist is strictly prohibited from carrying people up and down.
4. After the work is completed, the hoist pallet should be placed on the ground, then the power supply should be cut off and the upper and lower guardrail doors should be closed.
5. Always keep the environment around the hoist clean and hygienic.
Appropriate Modification:
Bucket elevators, as a widely used vertical conveying equipment, have been extensively applied in the grain, feed and seed processing industries. However, some problems emerged during its use. To enhance its working performance and reliability, modifications were made to it.
1. Add an anti-reversal device at the head of the bucket elevator. When the power is interrupted suddenly during the operation of the bucket elevator, reversing is very dangerous. During the lifting process of the bucket elevator, one side of it are upward hoppers full of materials, while the other side are downward empty unloaded hoppers. After the power is interrupted, the bucket elevator is bound to reverse due to the effect of gravity. The materials are unloaded to the bottom of the bucket elevator as the buckets reverse until they are piled up and the buckets get stuck. Because the reversal is an accelerated movement and then suddenly gets stuck, it is very easy to pull off the buckets, damage the belt, or even break it. In addition, the bottom of the bucket elevator is piled up with materials, which also prevent the bucket elevator from starting. Anti-reversal can be achieved through ratchet mechanisms.
2. Suction pipes and ventilation ports should be installed at the head and bottom of the bucket elevator to ensure that no negative pressure or dust overflow occurs during the unloading and feeding processes of the bucket elevator. A well-made conveying equipment must have reliable seals. But a good seal will inevitably generate a pressure difference during the material unloading and feeding processes, causing difficulties in feeding and unloading. The ventilation ports make the internal pressure of the bucket elevator basically equal to the external pressure. Proper suction can prevent dust from overflowing from ventilation areas, avoid wastes and keep the environment clean.
As a commonly used lifting equipment, bucket elevators are widely applied and have very clear classifications according to the different requirements of various industries. According to the transmission structure, they can be divided into:  
1. TD Series Bucket Elevators:
Its specifications include models such as TD100 (less commonly used), TD160, TD250, TD315, TD400, TD500, TD630, TD800, TD1000, among them TD160, TD250, and TD315 are commonly adopted.
2. TH Series Bucket Elevators:
The TH series bucket elevator is a commonly used lifting equipment. This series of bucket elevators adopts forged chain links as the transmission part, which has strong mechanical strength. It is mainly used for lifting powder, small particles and small block materials. Different from the TD series bucket elevators, it has a larger lifting capacity and higher operating efficiency. It is often used for lifting materials with a relatively large specific gravity.
3. NE Series Bucket Elevators:
The NE series plate chain bucket elevator is new type of bucket elevator. It adopts plate chain drive and is different from the old TB series plate chain bucket elevator. Its naming method is based on the lifting capacity rather than the width of the bucket. For example, NE150 refers to a lifting capacity of 150 tons per hour, not a bucket width of 150. The NE series bucket elevators feature a very high lifting efficiency. Depending on the lifting speed, they are further classified into NSE models and high-speed plate chain bucket elevators.
4. TG Series Bucket Elevator:
The TG series bucket elevator is a reinforced belt bucket elevator. Different from the TD series bucket elevator, the TG series bucket elevator uses steel wire belt as the transmission belt, which has a stronger transmission capacity. This series of bucket elevators are mostly used in grain transportation and are often referred to as grain-specific bucket elevators.
5. Other Models of Bucket Elevators:
Common bucket elevator models also include HL series chain bucket elevators, GTD series bucket elevators, GTH series bucket elevators, etc., which are all different names and evolved forms of the above models.
Cautions:
Bucket elevators are used to vertically lift block or granular materials such as limestone, coal, gypsum, and dry clay that have been crushed, as well as powdered materials such as cement and coal powder. According to the different speeds of the hopper's operation, bucket elevators can be classified into three forms: centrifugal discharge, gravity discharge and mixed discharge. The hopper speed of the centrifugal discharge is relatively fast, making it suitable for conveying materials with low abrasiveness such as powder, granules, and small blocks. The hopper speed of gravity discharge is relatively slow and it is suitable for conveying blocky materials with high specific gravity and high abrasiveness, such as limestone. The traction components of bucket elevators include several types such as chain links, plate chains and belts. The structure and manufacturing of the chain links are relatively simple, and its connection with the hopper is also very firm. When conveying materials with high abrasiveness, the wear of the chain is relatively small, but its own weight is relatively large. The plate chain structure is relatively solid and has a light self-weight, making it suitable for elevators  with large lifting capacity. However, the hinged joints are prone to wear. The structure of the belt is relatively simple, but it is not suitable for conveying abrasive materials. The material temperature of ordinary belts should not exceed 60ºC, while that of steel-rope belts can reach 80ºC and heat-resistant belts can reach 120ºC. The temperature of materials conveyed by chain links and plate chains can reach 250ºC.
