Description

Technical Field

[0001] The utility model relates to the technical field of coal feeding and receiving hoppers, in particular to an automatic recovery device for the accumulated coal receiving hopper at the head of a belt conveyor. Background Art

[0002] Belt conveyors are widely used in various types of wharves, power plants, mines, and factories as conveying devices, undertaking the displacement and transmission function of materials. The company currently has many types of belt conveyors for the efficient transfer of coal and ore. After long-term operation, a large amount of materials accumulate along the belt conveyor. In case of material blockage, the scattered coal is even more serious. If the belt conveyor is connected across large equipment such as stackers and ship loaders, the aggregate along the tail can be cleared back to the belt and discharged through the large equipment, but the aggregate at the head cannot be processed; if there is no large equipment connected across the belt conveyor, the aggregate along the line cannot be processed. The long-term accumulation of aggregate is prone to spontaneous combustion, posing a great safety hazard. Manually transporting the aggregate is time-consuming, laborious, and extremely inefficient, and in many places, the working conditions for transportation are not available. Summary of the Invention

[0003] The technical problem to be solved by the utility model is that it is difficult to transport the materials accumulated at the head of the conveyor belt and there are safety hazards.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: an automatic recovery device for the accumulated coal receiving hopper at the head of a belt conveyor, including a mounting frame for supporting the feeding belt, a receiving hopper fixedly arranged on the mounting frame, a feeding pipe extending to the lower part of the mounting frame connected to the bottom end of the receiving hopper, the receiving hopper is located directly below the discharging end of the feeding belt, and a diversion structure for decelerating the conveyed materials is arranged in the receiving hopper and the feeding pipe.

[0005] Preferably, the diversion structure includes a diversion plate fixedly connected in the receiving hopper, the diversion plate is located on one side of the discharging end of the feeding belt, the cross-section of the diversion plate is in an S shape, and a gap is arranged between the diversion plate and the discharging end of the feeding belt.

[0006] Preferably, both the top and bottom of the cross-section of the diversion plate are in an arc shape, and the top of the cross-section of the diversion plate bulges downward, and the bottom bulges upward.

[0007] Preferably, the diversion structure further includes baffle plates arranged along the axial direction of the feeding pipe, the baffle plates are distributed on both sides inside the feeding pipe and are inclined.

[0008] Preferably, the included angle between the baffle plate and the axis of the feeding pipe is 30°.

[0009] Preferably, a fixing frame with a triangular frame structure is fixedly arranged on the mounting frame, and the fixing frame covers the outside of the receiving hopper.

[0010] Preferably, a dust-proof net is provided at the top of the receiving hopper.

[0011] The utility model provides an automatic recovery device for the coal accumulation receiving hopper at the head of a belt conveyor. The blocked coal is transported to the discharging end of the feeding belt through the feeding belt. The coal falls into the receiving hopper. Through the diversion of the diversion structure, the flow of the coal is decelerated. The coal can not only smoothly fall into the receiving trailer arranged below the discharging pipe, but also decelerate the coal, reduce the flue gas generated by the falling of the coal, and use the receiving trailer to transfer the coal, improving the safety and efficiency of the aggregate handling of the belt conveyor.

[0016] As Figure 1 and Figure 2 shown, the present utility model provides an automatic recovery device for the coal accumulation receiving hopper at the head of a belt conveyor, including a mounting frame 1 for supporting the feeding belt 3. A receiving hopper 2 is fixedly arranged on the mounting frame 1. The bottom end of the receiving hopper 2 is connected with a discharging pipe 5 extending below the mounting frame 1. The receiving hopper 2 is directly below the discharging end of the feeding belt 3. A diversion structure for decelerating the conveyed material is arranged in the receiving hopper 2 and the discharging pipe 5.

[0017] The mounting frame 1 is used to raise the feeding belt 3. Cooperating with the receiving hopper 2 on the mounting frame 1, when coal accumulates on the feeding belt 3, the coal is transported to the receiving hopper 2 through the feeding belt 3. During the flow of the coal in the receiving hopper 2, the coal is diverted through the diversion structure, so that the coal contacts the inner side walls of the receiving hopper 2 and the discharging pipe 5, slowing down the flow of the coal, and enabling the coal to fall into the receiving trailer 8 below the discharging pipe 5 more slowly. After the receiving trailer 8 is filled with coal, the transportation of the feeding belt 3 is stopped. The receiving trailer 8 is connected by a vehicle and transported to the storage bin. Then, the empty receiving trailer 8 is transported below the discharging pipe 5 to continue receiving coal.

[0018] As Figure 2As shown in the figure. The diversion structure includes a diversion plate 6 fixedly connected inside the material receiving hopper 2. The diversion plate 6 is located on one side of the discharging end of the feeding belt 3. The cross-section of the diversion plate 6 is in an S shape, and there is a gap between the diversion plate 6 and the discharging end of the feeding belt 3. The diversion plate 6 divides the coal material falling from the feeding belt 3 into two streams. The small lump coal material at the bottom passes through the gap between the diversion plate 6 and the feeding belt 3, and the large lump coal material falls on the diversion plate 6. Through the diversion of the diversion plate 6, the large lump coal material slowly falls into the material receiving hopper 2. The diversion of the coal material enables the small lump coal material to fall first and be spread on the inner bottom of the receiving trailer 8, buffering the fall of the large lump coal material.

[0019] As Figure 2 shown in the figure. Both the top and bottom of the cross-section of the diversion plate 6 are arc-shaped, and the top of the cross-section of the diversion plate 6 bulges downward, and the bottom bulges upward. The arc-shaped structure at the top of the diversion plate 6 separates the large lump coal material, and the arc-shaped structure at the bottom of the diversion plate 6 diverts the large lump coal material, so that the large lump coal material falls vertically directly after passing through the diversion plate 6 and does not impact the material receiving hopper 2.

[0020] As Figure 2 shown in the figure. The diversion structure further includes a baffle plate 7 arranged along the axial direction of the blanking pipe 5. The baffle plates 7 are distributed on both sides inside the blanking pipe 5 and are inclined. By arranging the baffle plate 7, during the falling process of the small lump coal material, the baffle plate 7 repeatedly guides the small lump coal material, reducing the falling speed of the small lump coal material and enabling directional blanking at the same time.

[0021] As a preferred embodiment of the present invention, to ensure the blanking efficiency while reducing the falling speed. The included angle between the baffle plate 7 and the axis of the blanking pipe 5 is 30°.

[0022] As Figure 1 and Figure 2 shown in the figure. A fixing frame 4 with a triangular frame structure is fixedly arranged on the mounting frame 1. The fixing frame 4 covers the outside of the material receiving hopper 2. The fixing frame 4 is connected to the outer side wall of the material receiving hopper 2 to stably support the material receiving hopper 2.

[0023] As Figure 2 shown in the figure, to avoid generating a large amount of dust during the blanking process. A dust-proof net 9 is arranged at the top of the material receiving hopper 2.
