[0017] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0018] In order to thoroughly understand the present invention, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0019] Reference Figure 1As shown, the utility model provides a vehicle-mounted mobile unloading trolley dust removal system, the mobile unloading trolley is rollingly installed on a track bracket, pulleys are installed on the mobile unloading trolley and the track bracket, a feeding belt 11 is connected between the pulleys of the mobile unloading trolley and the track bracket, and the mobile unloading trolley is installed with a belt cover 7.

[0020] The dust removal system of the utility model is fixedly installed on the frame 8 of the mobile unloading trolley, and mainly includes a cavity 4, a funnel sealing cover 1, a fan 10, a filter cartridge 12, an air suction pipe 5, an ash unloading chute 6, and a clean box 9. The bottom opening of the cavity 4 is provided with a gate valve 15, and the bottom of the gate valve 15 is connected to the ash unloading chute 6, and the bottom opening of the ash unloading chute 6 is located above the feeding belt 11. The cavity 4 is provided with two air inlets: the first air inlet is connected to the funnel sealing cover 1, and the funnel sealing cover 1 is arranged just above the ash unloading point 2 of the mobile unloading trolley; the second air inlet is connected to the air suction pipe 5, and the bottom opening of the air suction pipe 5 is located near the bottom opening of the ash unloading chute 6. The cavity 4 is provided with a filter cartridge 12, and one end of the clean box 9 is connected to the filter outlet of the filter cartridge 12, and the other end is connected to the fan 10.

[0021] The principle of the dust removal system of the utility model is as follows: the fan 10 provides negative pressure for the cavity 4, sucks air from the two air inlets of the cavity 4, filters through the filter cartridge 12, and then sends it into the clean box 9 and finally discharges it into the atmosphere. In this process, the funnel sealing cover 1 collects the dust raised by the ash discharge point 2 into the cavity 4 and drops it into the ash collecting hopper 14. After opening the gate valve 15, the collected dust is transported to the feeding belt 11 through the ash discharge chute 6, and the feeding belt 11 continues to transport the recovered dust forward. When the recovered dust reaches the front end of the feeding belt, it falls under the action of gravity and is collected and collected for recycling. The ash discharge chute 6 transports the material to the feeding belt 11, which will generate secondary dust. The dust in the belt cover 7 can be collected again into the cavity 4 through the suction pipe 5, effectively avoiding secondary dust.

[0022] The principle of the dust removal system of the utility model is: when the fan 10 generates negative pressure, it can suck the dust raised by the ash discharge point 2 into the cavity of the cavity 4. Under the action of gravity, these dusts will naturally fall into the ash collecting hopper 14. When the collected dust needs to be recycled, the gate valve 15 is opened, and the ash discharge chute 6 will transport the dust to the feeding belt 11. However, secondary dust will be generated in the process of the ash discharge chute 6 transporting the material to the feeding belt 11. In order to solve this problem, through the action of the suction pipe 5, the dust in the belt cover 7 can be collected again into the cavity of the cavity 4, thereby effectively avoiding the generation of secondary dust.

[0023] The utility model dust removal system realizes effective dust collection and avoids the generation of secondary dust through ingenious design and reasonable layout. This system not only improves the dust removal efficiency, but also is beneficial to environmental protection and resource recycling and reuse, and has broad application prospects and promotion value.

[0024] In an optional embodiment, the dust removal system further includes a dust cleaning system, which is provided with an air bag and a plurality of spray valves 13 connected to the air bag. The jet port of the spray valve 13 is connected to the clean box 9. The high-pressure gas stored in the air bag is used to clean the dust attached to the inner wall of the filter cartridge 12 through the spray valve 13. When the resistance of the dust collector reaches the set value, the control system issues a dust cleaning command, and the dust cleaning system starts to work. First, the solenoid valve opens the spray valve immediately after receiving the signal, and the compressed air in the air bag is sprayed into the cartridge through the spray pipe to achieve dust cleaning. The fallen dust is transported to the feeding belt 11 for recycling through the ash collecting hopper 14 and the ash unloading chute 6. When the control signal stops, the solenoid valve is closed, the spray valve is closed, and the spraying stops.

[0025] A power rail is installed on the track, and a busbar for supplying power to the dust removal system is installed on the frame 8 of the mobile unloading trolley. The busbar and the power rail slide together. The dust collector moves back and forth with the unloading trolley. The power supply of the dust collector adopts the busbar, and the air supply adopts the compressed air hose and the slide. The differential pressure signal of the dust collector, the start and stop of the dust removal fan and the fault signal have the ability of remote transmission.

[0026] In an optional embodiment, a plurality of filter cartridges 12 distributed in an array are installed in the cavity 4 to improve the filtering efficiency and avoid clogging.

[0027] The utility model provides a vehicle-mounted dust collector directly mounted on the frame of a discharge trolley. The dust collector support frame uses the frame on the original mobile discharge trolley and is modified to reinforce the support. The collected ash falls directly on the conveyor belt and is transported away. The dust collector can work continuously, and the discharged ash does not need to be handled separately, saving labor and space. At the same time, an air duct is added to introduce secondary dust into the dust removal and filtration box, and the raised ash is recycled again. A chimney 3 is added at the other end of the fan 10 to lead the filtered clean air into the air without raising dust again.

[0028] The above describes the preferred embodiments of the utility model. It should be understood that the utility model is not limited to the above-mentioned specific implementation methods, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the utility model without departing from the scope of the technical solution of the utility model, or modify them into equivalent embodiments of equivalent changes, which does not affect the essential content of the utility model. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of protection of the technical solution of the utility model.
