Description

Technical Field

[0001] This utility model relates to the field of conveyor belt transfer station technology, specifically to a dust suppression device for conveyor belt transfer stations. Background Technology

[0002] A transfer station, as it is known in ports, refers to a place where materials are transferred from one conveyor to another or a material handling device. It is also called a "transfer tower" or transfer room.

[0003] The existing equipment has some drawbacks during use. For example, when the material falls from the upper conveyor belt to the lower conveyor belt, the impact force generated by the drop causes dust particles on the surface of the material to be stirred up, which seriously pollutes the environment and harms the health of the workers. In addition, the material transfer process generates induced wind, which accelerates the spread of dust. Utility Model Content

[0004] The purpose of this invention is to provide a dust suppression device for conveyor belt transfer stations, which solves the problem that dust particles on the surface of materials are stirred up by the impact force generated by the drop difference when materials fall from the upper belt to the lower belt.

[0005] This utility model provides the following technical solution: a dust suppression device for a conveyor belt transfer station, comprising a base plate and baffles fixedly installed on both sides of the upper surface of the base plate. An upper-level conveyor belt is arranged between the top baffles, and a lower-level conveyor belt is arranged between the bottom baffles. A top plate is fixedly installed on the upper surface of one side of each of the two baffles. A first dust curtain and a second dust curtain are fixedly installed on both sides of the top plate, respectively. A fixed frame is embedded in the upper surface of the top plate, and the bottom end of the fixed frame corresponds to the opening on the top plate. A movable component for auxiliary dust suppression is arranged inside the fixed frame, and a spray component for dust suppression is arranged on the movable component.

[0006] As a preferred embodiment of the above technical solution, the movable component includes a drive motor fixedly installed on the outer wall of the fixed frame. A threaded rod is fixedly installed at the output end of the drive motor. One end of the threaded rod passes through the fixed frame and its end is rotatably connected to the inner wall of the fixed frame. A movable sleeve is threaded onto the outer wall of the threaded rod. A support block is fixedly installed on the lower end face of the movable sleeve, and an mounting plate is fixedly installed at the bottom end of the support block.

[0007] As a preferred embodiment of the above technical solution, a limiting slide rod is provided horizontally through the movable sleeve, both ends of which are fixed to the inner sidewall of the fixed frame, and the movable sleeve slides on the outer wall of the limiting slide rod.

[0008] As a preferred embodiment of the above technical solution, a rectangular opening is provided horizontally on the upper surface of the fixed frame.

[0009] As a preferred embodiment of the above technical solution, the spray assembly includes spray heads fixedly installed on both sides of the mounting plate. The water inlet ends of the two spray heads are fixedly connected to water guide pipes. One end of each water guide pipe passes through a rectangular opening and is connected to a water pump. The water inlet end of the water pump is connected to a water delivery pipe. An installation base is fixedly installed on the lower end face of the water pump. The installation base is fixedly installed on the upper end face of the top plate.

[0010] As a preferred embodiment of the above technical solution, a dust-reducing net for adhering to dust is fixedly installed on the side wall of the baffle, and the dust-reducing net is located below the water outlet of the spray head.

[0011] As a preferred embodiment of the above technical solution, a baffle plate is fixedly connected to the bottom plate located on one side of the lower conveyor belt.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, when materials are conveyed from the upper conveyor belt to the lower conveyor belt, the transfer process is completed. During this process, the first dust curtain, the second dust curtain, and the top plate together form a relatively closed environment, further reducing dust spillage and preventing the induced wind generated during the material transfer from accelerating dust diffusion. At this time, the spray assembly is activated, spraying water mist or dust suppressant onto the material and the surrounding space to reduce dust generation and diffusion. The set moving component drives the spray assembly to move horizontally, thereby expanding the range of dust suppression spraying. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Example

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a dust suppression device for a conveyor belt transfer station, including a base plate 1 and baffles 11 fixedly installed on both sides of the upper surface of the base plate 1. An upper-level conveyor belt 12 is arranged between the top baffles 11, and a lower-level conveyor belt 13 is arranged between the bottom baffles 11. A top plate 14 is fixedly installed on the upper surface of one side of the two baffles 11. A first dust curtain 15 and a second dust curtain 16 are fixedly installed on both sides of the top plate 14, respectively. A fixing frame 17 is embedded in the upper surface of the top plate 14. The bottom end of the fixing frame 17 corresponds to the opening on the top plate 14, so that the interior of the fixing frame 17 is through the top plate 14. A movable component 2 for auxiliary dust suppression is provided on the side. A spray component 3 for dust suppression is provided on the movable component 2. In specific use, when the material is transported from the upper conveyor belt 12 to the lower conveyor belt 13, the transfer process is completed. During this process, the first dust curtain 15, the second dust curtain 16 and the top plate 14 together form a relatively closed environment to further reduce the overflow of dust. At this time, the spray component 3 is activated to spray water mist or dust suppressant to the space above and around the material to reduce the generation and diffusion of dust. The movable component 2 drives the spray component 3 to move horizontally, thereby expanding the range of dust suppression spraying.

[0022] As one implementation method in this embodiment, such as Figure 3 As shown, the movable component 2 includes a drive motor 21 fixedly mounted on the outer wall of the fixed frame 17. A threaded rod 22 is fixedly mounted on the output end of the drive motor 21. One end of the threaded rod 22 passes through the fixed frame 17 and is rotatably connected to the inner wall of the fixed frame 17. A movable sleeve 23 is threaded onto the outer wall of the threaded rod 22. A support block 24 is fixedly mounted on the lower end face of the movable sleeve 23. An mounting plate 25 is fixedly mounted on the bottom end of the support block 24. A limiting slide rod 26 is transversely arranged on the movable sleeve 23. The two ends of the limiting slide rod 26 are connected to the upper and lower ends of the sliding sleeve 23. All are fixed to the inner wall of the fixed frame 17. The movable sleeve 23 slides on the outer wall of the limiting slide bar 26. In actual use, when the drive motor 21 starts, the threaded rod 22 starts to rotate, and the movable sleeve 23 will move along the axial direction of the threaded rod 22. At the same time, the movable sleeve 23 also slides on the outer wall of the limiting slide bar 26. This sliding method ensures the stability and accuracy of the movable sleeve 23. The support block 24 and the mounting plate 25 move with the movement of the movable sleeve 23, thereby realizing the adjustment of the position of the spray assembly 3.

[0023] As one implementation method in this embodiment, such as Figure 3As shown, a rectangular opening 171 is horizontally provided on the upper surface of the fixed frame 17. The spray assembly 3 includes spray heads 31 fixedly installed on both sides of the mounting plate 25. Water inlet ends of both spray heads 31 are fixedly connected to water guide pipes 32. One end of each water guide pipe 32 passes through the rectangular opening 171 and is connected to a water pump 33. The water inlet end of the water pump 33 is connected to a water delivery pipe 34. A mounting base 35 is fixedly installed on the lower surface of the water pump 33. The mounting base 35 is fixedly installed on the upper surface of the top plate 14. In actual use, when it is necessary to start the spray... When component 3 is in operation, the water pump 33 draws water from the water supply pipe 34 and pressurizes it to deliver it to the water guide pipe 32 (the water supply pipe 34 is connected to an external water source). The water guide pipe 32 delivers the water output by the water pump 33 to the water inlet of the spray head 31. As the water pump 33 continues to run, the spray head 31 begins to spray water mist or water droplets to achieve the dust reduction effect on the air. During the entire spraying process, components such as the mounting plate 25, the moving sleeve 23, and the drive motor 21 move to ensure that the spray head 31 can cover the area that needs to be sprayed.

[0024] As one implementation method in this embodiment, such as Figure 4 As shown, a dust-collecting net 4 for adhering to dust is fixedly installed on the side wall of the baffle 11. The dust-collecting net 4 is located below the water outlet of the spray head 31. The dust-collecting net 4 will be wetted by water mist, and the dust particles will be wetted by water mist and adhere to it, effectively capturing and adhering to the dust.

[0025] As one implementation method in this embodiment, such as Figure 4 As shown, a baffle plate 5 is fixedly connected to the bottom plate 1 located on one side of the lower conveyor belt 13. The baffle plate 5 is used to prevent materials from slipping to the edge of the lower conveyor belt 13 and affecting normal material conveying.

[0026] Working principle: During use, when materials are conveyed from the upper conveyor belt 12 to the lower conveyor belt 13, the transfer process is completed. During this process, the first dust curtain 15, the second dust curtain 16, and the top plate 14 together form a relatively closed environment, further reducing dust overflow. Then, the spray assembly 3 is activated, and the water pump 33 draws water from the water supply pipe 34 and pressurizes it to the water guide pipe 32 (the water supply pipe 34 is connected to an external water source). The water guide pipe 32 then delivers the water output by the water pump 33 to the water inlet of the spray head 31. As the water pump 33 continues to operate, the spray head 31 begins to spray water mist or water droplets to achieve the dust suppression effect on the air. In order to expand the dust suppression range, after the drive motor 21 is started, the threaded rod 22 begins to rotate, and the moving sleeve 23 will move along the axial direction of the threaded rod 22. At the same time, the moving sleeve 23 also slides on the outer wall of the limiting slide bar 26. This sliding method ensures the stability and accuracy of the moving sleeve 23. The support block 24 and the mounting plate 25 move with the movement of the moving sleeve 23, thereby realizing the adjustment of the position of the spray assembly 3.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
