Are the hopper forms of NE, TH, HL hoists the same?
The hopper of the bucket elevator is divided into three types in terms of structure: a deep bucket and a shallow bucket with an arc-shaped bottom, and a pointed bucket (different slot hopper) with a guiding side wall. Today we mainly introduce what kind of materials the buckets are suitable for. Each of the three types of hoppers has a range of applicable materials. When selecting, customers can consult our technicians, and let the technicians correctly select the appropriate hopper structure according to the specific material conditions to achieve the best lifting effect.
The characteristic of the deep bucket at the bottom of the arc is that the front edge is slightly inclined to the horizontal (65° angle with the vertical section of the back of the bucket) and the depth is large. This kind of bucket is mainly used to unload dry, easy-flowing, non-sticky and easy-to-throw granular materials, such as dry sand and small pieces of coal. The design of the hopper is mainly to determine the type, volume and main geometric dimensions (width B, reach A and height H, etc.). This kind of bucket has high lifting efficiency and large load capacity, but it has high requirements on the fluidity and dryness of the material.
The characteristic of the shallow bucket with the arc bottom is that the front edge of the hopper and the vertical section of the back of the bucket have a larger inclination (at a 45° angle) and a smaller depth. This kind of bucket is mainly used to unload wet and poorly fluid granular materials, such as wet sand and wet coal. From the structural characteristics of this hopper, it can be known that due to its small depth and large inclination of the front edge, the hopper can be easily unloaded when unloading. Both the deep bucket and the shallow bucket have arc-shaped bottoms, which will not make the material stick to the bottom of the bucket, so it is good for unloading. This kind of hopper is only used on bucket elevators with hoppers arranged at intervals. The hopper spacing of the bucket elevator on the unloader is generally in the range of 400 mm to 500 mm. When using C-80 chain, the hopper can be separated by three chain links. This kind of bucket has lower lifting efficiency than the deep bucket, but it is not easy to stick to the bucket when lifting wet materials, and the unloading effect is good. The sharp-angled hopper (guide trough hopper) with guiding sides is mainly used for bucket elevators where the hopper is arranged continuously. When these hoppers are wound around the upper sprocket, the front wall of the hopper and the two protruding side walls form a guide groove, which is used to guide the flow of material discharged from the rear fabric hopper.
