Description

Technical Field

[0001] This utility model belongs to the field of coal sample preparation technology, specifically relating to a dust removal device for preparing coal samples. Background Technology

[0002] In coal-related production, processing, and research fields, coal sample processing is a common and important step. However, in the process of coal sample processing, a large amount of coal dust is inevitably generated. If this coal dust is not effectively treated, it will cause serious pollution to the working environment and endanger the health of workers. On the other hand, the direct emission of a large amount of coal dust also causes a serious waste of resources.

[0003] A search revealed that Chinese patent CN215466946U discloses a dust removal device for preparing coal samples. Addressing the problem that existing dust removal devices use pipes inserted into the coal sample preparation box to suck up dust, but the pipes are fixed at one end, making it impossible to thoroughly clean all corners of the box, this patent solves the problem by using a rotating motor that can drive the dust suction hood to swing 360 degrees via a crank, thus thoroughly cleaning all spaces within the coal sample preparation box.

[0004] Although the dust removal equipment can achieve good dust removal effect during use, it cannot effectively separate and collect coal dust from the air, resulting in continuous environmental pollution, waste of coal dust resources, difficulty in achieving centralized collection and reuse of coal dust, and failure to fully utilize resources. Utility Model Content

[0005] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0006] This utility model provides the following technical solution: a dust removal device for preparing coal samples, including a dust removal device box, a bottom plate fixedly connected to the bottom of the dust removal device box, and a dust suction mechanism provided on the top of the bottom plate;

[0007] The dust collection mechanism includes a hollow dust collection frame, which is positioned between the dust collection equipment box and the equipment base plate. A dust collection port is formed on the inner wall surface of the hollow dust collection frame, and an isolation net is fixedly installed inside the dust collection port. A dust extraction shell is fixedly connected to the top of the hollow dust collection frame, and a telescopic flexible hose is fixedly connected between the dust extraction shell and the inner wall of the dust collection equipment box. A connecting pipe is fixedly connected to the top of the telescopic flexible hose, and a dust collection box is fixedly connected to one end of the connecting pipe. An exhaust fan is installed on one side of the dust collection box, and a dustproof net is fixedly installed on the inner wall of the dust collection box. An inclined dust discharge base is fixedly installed between the dustproof net and the inner wall of the dust collection box, and a dust discharge pipe is fixedly connected to one side of the dust collection box.

[0008] Furthermore, the dust collection box is fixedly installed on the top of the dust removal equipment box, and one end of the connecting pipe and the dust discharge pipe both pass through the dust collection box and extend into the interior of the dust collection box. An electromagnetic valve is installed inside the dust discharge pipe.

[0009] Furthermore, an elastic mechanism is provided between the dust removal equipment box and the hollow dust removal frame. The elastic mechanism includes a first fixing plate, which is fixed on both sides of the hollow dust removal frame. A second fixing plate is fixedly connected to both inner walls of the dust removal equipment box.

[0010] A lifting rod is fixedly connected to the top of the second fixed plate. The lifting rod is slidably connected to the first fixed plate. A spring is sleeved on the outside of the lifting rod. The top of the spring is connected to the bottom of the first fixed plate, and the bottom of the spring is connected to the top of the second fixed plate.

[0011] Furthermore, mounting plates are fixedly connected to both sides of the inner wall of the dust removal equipment box, and telescopic cylinders are fixedly installed on the top of the mounting plates. Fixed baffles are fixedly connected to both sides of the hollow dust removal frame.

[0012] Furthermore, a lifting block is fixedly connected to the top of the telescopic cylinder, and the lifting block is located directly below the fixed baffle.

[0013] Furthermore, the number of both the telescopic flexible hose and the connecting pipe is set to two or more, and the connecting pipe is set to an L-shape.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] By setting up a dust collection mechanism, a fan generates suction, and the dust is quickly sucked into the dust collection box using a dust inlet and a hollow dust collection frame, ensuring a good dust removal effect. This effectively reduces the pollution of coal dust to the environment and allows the coal dust to be collected in the dust collection box for easy reuse, improving resource utilization and avoiding waste. At the same time, the coal dust slides down due to its own gravity, facilitating the centralized collection and treatment of the coal seam. The hollow dust collection frame also improves the dust removal and suction effect.

[0016] By setting up a spring mechanism, the lifting block hits the fixed baffle, causing the lifting rod to slide on the first fixed plate. This causes the spring to continuously compress and rebound, resulting in the hollow dust collector frame vibrating up and down. This facilitates the vibration and cleaning of the isolation net inside the dust suction port, preventing coal ash blockage. The coal ash on the hollow dust collector frame and the isolation net can be vibrated and fall off and be sucked back into the dust collection box, improving the self-cleaning effect of the overall device and enhancing the coal ash recovery effect.

[0026] The dust collection mechanism includes a hollow dust collection frame 3, which is set between the dust collection equipment box 1 and the equipment base plate 2. A dust collection port 4 is opened on the inner wall surface of the hollow dust collection frame 3. An isolation net 5 is fixedly installed inside the dust collection port 4. A dust extraction shell 6 is fixedly connected to the top of the hollow dust collection frame 3. A telescopic hose 7 is fixedly connected between the dust extraction shell 6 and the inner wall of the dust collection equipment box 1. A connecting pipe 8 is fixedly connected to the top of the telescopic hose 7. A dust collection box 9 is fixedly connected to one end of the top of the connecting pipe 8. An exhaust fan 10 is installed on one side of the dust collection box 9. A dustproof net 11 is fixedly installed on the inner wall of the dust collection box 9. An inclined dust discharge base 12 is fixedly installed between the dustproof net 11 and the inner wall of the dust collection box 9. A dust discharge pipe 13 is fixedly connected to one side of the dust collection box 9.

[0027] As attached Figure 1, 2 As shown in Figures 4 and 5, the dust collection box 9 is fixedly installed on the top of the dust removal equipment box 1. One end of the connecting pipe 8 and the dust discharge pipe 13 both pass through the dust collection box 9 and extend into the interior of the dust collection box 9. An electromagnetic valve 14 is installed inside the dust discharge pipe 13 to facilitate the collection and centralized discharge of coal dust.

[0028] As attached Figure 1-4 As shown, an elastic mechanism is provided between the dust removal equipment box 1 and the hollow dust removal frame 3. The elastic mechanism includes a first fixed plate 15, which is fixed to both sides of the hollow dust removal frame 3. A second fixed plate 16 is fixedly connected to the inner walls of both sides of the dust removal equipment box 1. A lifting rod 17 is fixedly connected to the top of the second fixed plate 16. The lifting rod 17 is slidably connected to the first fixed plate 15. A spring 18 is sleeved on the outside of the lifting rod 17. The top of the spring 18 is connected to the bottom of the first fixed plate 15, and the bottom of the spring 18 is connected to the top of the second fixed plate 16. The spring 18 facilitates the up-and-down vibration of the hollow dust removal frame 3.

[0029] As attached Figure 3 , 4 As shown, mounting plates 19 are fixedly connected to both sides of the inner wall of the dust removal equipment box 1. A telescopic cylinder 20 is fixedly installed on the top of the mounting plate 19. Fixed baffles 22 are fixedly connected to both sides of the hollow dust removal frame 3. A lifting block 21 is fixedly connected to the top of the telescopic cylinder 20. The lifting block 21 is located directly below the fixed baffle 22, so that the hollow dust removal frame 3 can move up and down by hitting the fixed baffle 22 through the lifting block 21.

[0030] As attached Figure 1 , 3 As shown in Figure 4, the number of telescopic hoses 7 and connecting pipes 8 are both set to two or more, and the connecting pipes 8 are set to L-shape to facilitate the entry of coal dust and air into the dust collection box 9.

[0031] Working principle of this utility model: In the process of using the dust removal equipment for preparing coal samples, the exhaust fan 10 installed at one end of the dust collection box 9 is first started, so that the exhaust fan 10 draws the air inside the dust collection box 9. Then, through the connecting pipe 8 and the telescopic hose 7, the suction port 4 opened on one side of the hollow dust collection frame 3 generates suction, so that the coal dust follows the air into the hollow dust collection frame 3. Then, it enters the dust collection box 9 through the dust collection shell 6, the telescopic hose 7 and the connecting pipe 8. It is isolated by the dustproof net 11 installed inside the dust collection box 9, which effectively achieves the effect of dust suction of coal ash. At the same time, it is convenient to collect and reuse coal ash. By opening the solenoid valve 14 inside the dust discharge pipe 13, the coal dust slides down through the inclined dust discharge base 12 into the dust discharge pipe 13 due to its own gravity and is discharged in a centralized manner.

[0032] By activating the telescopic cylinder 20, the lifting block 21 moves up and down continuously, causing the lifting block 21 to strike the fixed baffle 22, which in turn causes the lifting rod 17 to slide on the first fixed plate 15, causing the spring 18 to continuously compress and rebound, thus causing the hollow dust collector frame 3 to vibrate up and down continuously. This facilitates the vibration cleaning of the isolation net 5 inside the dust suction port 4, preventing coal ash blockage and improving the coal ash recovery effect.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
