Benefits of technology

[0014] This dust cover for the feed inlet of a coal preparation crusher with dust removal function consists of a dust cover body, an auxiliary box, a suction square pipe, a negative pressure pump, a collection box, a filter plate, an electric telescopic rod, a scraper, and a sealing assembly. The negative pressure pump draws air from the auxiliary box, creating a negative pressure. The suction square pipe continuously draws dust-laden air from the dust cover body into the auxiliary box, where it is filtered by the filter plate, leaving dust on its surface. The filtered air is then discharged by the negative pressure pump, and the electric telescopic rod moves the scraper, causing it to continuously rub against the filter plate, pushing the dust off the filter plate and into the collection box. This completes the collection of dust from the dust cover, improving environmental protection during the operation of the coal preparation crusher. Furthermore, the sealing assembly prevents air leakage, solving the problem that dust covers only provide a certain degree of shielding and cannot actively remove dust from inside the cover, resulting in poor dust prevention and dust leakage that pollutes the environment. This significantly improves the effectiveness of the dust cover for the feed inlet of the coal preparation crusher.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0025] Please see Figures 1-4 This utility model embodiment provides a dust cover for the feed inlet of a coal preparation crusher with dust removal function, including a dust cover body 1, and a dust removal mechanism 2 is provided inside the dust cover body 1;

[0026] The dust removal mechanism 2 includes an auxiliary box 201. The right side of the auxiliary box 201 is fixedly connected to the left side of the dust cover body 1. An air suction square pipe 202 is fixedly connected to the upper surface of the auxiliary box 201. The right end of the air suction square pipe 202 is fixedly connected to the left side of the dust cover body 1. A negative pressure pump 203 is fixedly connected to the left side of the auxiliary box 201. A support block 4 is fixedly connected to the outer surface of the negative pressure pump 203. The right side of the support block 4 is fixedly connected to the left side of the auxiliary box 201. The support block 4 can support the negative pressure pump 203, provide an effective force point for the negative pressure pump 203, increase the firmness of the connection between the negative pressure pump 203 and the support block 4, and improve the service life of the negative pressure pump 203.

[0027] The auxiliary box 201 has a collection box 204 slidably connected inside. The right side of the collection box 204 is fixedly connected to an auxiliary handle 5. The outer surface of the auxiliary handle 5 is covered with an anti-slip sleeve 6. The auxiliary handle 5 can provide a good force-bearing position for the collection box 204, increasing the convenience when pulling the collection box 204. The anti-slip sleeve 6 can also increase the convenience when gripping the auxiliary handle 5.

[0028] The inner wall of the auxiliary box 201 is fitted with a filter plate 205. Two reinforcing rings 7 are fixedly connected to the outer surface of the auxiliary handle 5. The end of each reinforcing ring 7 near the collection box 204 is fixedly connected to the front of the collection box 204. The reinforcing rings 7 can increase the fixed connection area between the auxiliary handle 5 and the collection box 204, making the connection between the two more secure, preventing the possibility of breakage at the connection after long-term use, and increasing the durability of the device.

[0029] An electric telescopic rod 206 is installed above the auxiliary box 201. The telescopic end of the electric telescopic rod 206 passes through the auxiliary box 201 and is fixedly connected to a scraper 207. The left side of the scraper 207 contacts the right side of the filter plate 205. A sturdy frame 8 is fixedly connected to the outer surface of the electric telescopic rod 206. The bottom surface of the sturdy frame 8 is fixedly connected to the upper surface of the auxiliary box 201. The sturdy frame 8 can support the electric telescopic rod 206, provide an effective force point for the electric telescopic rod 206, increase the firmness of the connection between the electric telescopic rod 206 and the auxiliary box 201, and improve the service life of the electric telescopic rod 206.

[0030] The outer surface of the collection box 204 is provided with a sealing component 3, which includes a first sealing gasket 301. The inner wall of the first sealing gasket 301 is fixedly connected to the outer surface of the collection box 204. Two sets of iron blocks 302 arranged at equal distances are fixedly connected to the inner wall of the first sealing gasket 301. A second sealing gasket 303 is fixedly connected to the inner wall of the auxiliary box 201. Two sets of magnets 304 arranged at equal distances are fixedly connected to the inner wall of the second sealing gasket 303. The attraction between the iron blocks 302 and the magnets 304 makes the first sealing gasket 301 and the second sealing gasket 303 come into close contact, thereby completing the sealing of the collection box 204 and the auxiliary box 201, preventing air from leaking from the gaps at the connection, and increasing the dust removal effect.

[0031] When using this utility model: First, connect the negative pressure pump 203 and the electric telescopic rod 206 to the power supply, and connect the bottom surface of the dust cover body 1 to the feed port of the coal preparation crusher. Then, add coal into the coal preparation crusher through the dust cover body 1. When it is necessary to clean the dust generated during coal crushing, start the negative pressure pump 203. The negative pressure pump 203 draws air from the auxiliary box 201 to create a negative pressure environment. At this time, the suction square pipe 202 will draw the dust-laden air from the dust cover body 1 into the auxiliary box 201, and filter the dust in the air through the filter plate 205, leaving the dust on the surface of the filter plate 205. The filtered air is then discharged through the negative pressure pump 203.

[0032] Then, the electric telescopic rod 206 drives the scraper 207 to move up and down repeatedly. When the scraper 207 moves, it will continuously rub against the filter plate 205 and push the dust on the surface of the filter plate 205 into the collection box 204, thereby completing the dust collection and preventing the dust from being discharged through the dust cover body 1 after crushing and polluting the environment, thus increasing the environmental protection in the operation of the coal preparation crusher.

[0033] When further processing of the collected dust is required, pull the auxiliary handle 5 to move the collection box 204 outward. At this time, the iron block 302 and the magnet 304 will separate, allowing the collection box 204 to be removed from the auxiliary box 201. The dust inside the collection box 204 can then be processed. After processing, the collection box 204 is slid back into the auxiliary box 201. At this time, the magnet 304 will magnetically attract the iron block 302, causing the first sealing gasket 301 and the second sealing gasket 303 to fit tightly together, thus ensuring the sealing of both and preventing air from leaking out from the gaps, thereby increasing the dust removal effect.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
