Description

Technical Field

[0001] The utility model relates to the technical field of material conveying in the metallurgical mine industry, and particularly relates to a blanking device for conveying loose materials. Background Art

[0002] In the iron and steel smelting industry, materials and raw materials mined in the mining industry are mostly granular, powdered or irregular loose materials, and the general transportation method used is belt conveyor transportation.

[0003] When multiple belt conveyors are used for conveying and there is a height difference between the front and rear belt conveyors, a belt funnel is often arranged between the head of the front belt and the tail of the rear belt. The belt funnel is an important part of the belt system.

[0004] During the smelting process, production is carried out continuously throughout the day, and the belt funnel also runs continuously for a long time. The conveyed materials are often of high hardness, and long-term conveying will cause erosion and wear of the belt funnel. Therefore, the belt funnel wears quickly and needs frequent maintenance. The maintenance process involves confined space operations, high-altitude operations, and electric welding operations, and personnel are at risks such as scalding, electric shock, high-altitude falling, and object hitting.

[0005] In view of the above reasons, the utility model provides a blanking device for conveying loose materials to solve the above technical problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a blanking device for conveying loose materials, which can buffer the materials flowing down from the belt conveyor, avoid directly scouring the belt funnel, and cause its rapid wear and frequent maintenance.

[0007] The utility model provides a blanking device for conveying loose materials, including: a first belt conveyor, a second belt conveyor and a belt funnel. The belt funnel is arranged between the tail of the first belt conveyor and the head of the second belt conveyor, and the tail of the first belt conveyor is higher than the head of the second belt conveyor. A material guiding box is arranged on the inner wall of the belt funnel on the side far from the first belt conveyor. A blanking channel is formed between the material guiding box and the inner wall of the belt funnel. The materials flowing out from the tail of the first belt conveyor fall into the material guiding box in a parabolic shape and slide down along the blanking channel to accumulate on the surface of the second belt conveyor for conveying by it.

[0008] Preferably, the height difference between the tail of the first belt conveyor and the head of the second belt conveyor is greater than the height of the belt funnel.

[0009] Preferably, the top opening of the belt hopper is lower than and connected to the tail of the first belt conveyor, and the bottom opening of the belt hopper is located above the surface of the second belt conveyor.

[0010] Preferably, the top opening of the belt hopper is larger than its bottom opening.

[0011] Preferably, the cross-section of the belt hopper is rectangular.

[0012] Preferably, the bottom of the belt hopper is fixedly connected to the ground through a bracket.

[0013] Preferably, the bottom of the belt hopper is fixedly connected to the side of the second belt conveyor through a bracket.

[0014] Preferably, the distance from the bottom opening of the belt hopper to the surface of the second belt conveyor is greater than the maximum diameter of the material.

[0015] Preferably, the cross-section of the material guiding box is rectangular, and the material guiding box is integrally welded to the inner wall of the belt hopper or detachably connected through fastening screws.

[0016] Preferably, triangular diversion plates extending from its side plates are provided on both sides of the top of the material guiding box.

[0017] Compared with the prior art, the present utility model has the following beneficial effects:

[0018] By providing a material guiding box on the inner side wall of the belt hopper, the material flowing out from the end of the first belt conveyor falls into the material guiding box from the top in a parabolic shape, flows down along the feeding channel, accumulates on the surface of the second belt conveyor, and is then sent out by the second belt conveyor. By providing the material guiding box, the scouring effect of the material on the belt hopper can be reduced, rapid wear of the belt hopper can be avoided, the maintenance frequency can be reduced, and thus the danger that may be brought by maintenance work can be avoided.
