Specific embodiments

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Embodiment:

[0034] A dust removal device for use in mining equipment, as Figures 1-9 shown, includes a separation tank 1, and a discharge port is provided on the inner bottom surface of the separation tank 1. An opening and closing door 101 is provided on the surface of the separation tank 1. By setting the opening and closing door 101, the purpose of cleaning the inside of the separation tank 1 can be achieved by controlling its opening and closing; it should be noted that the opening and closing door 101 and the separation tank 1 are sealed by a sealing strip to ensure the airtightness of the separation tank 1; a water injection port 102 is connected to the upper end of the separation tank 1, and the upper end of the water injection port 102 is connected to a water supply source for delivering water for dust reduction.

[0035] Among them, the lower end of the separation tank 1 is connected to an intake pipe 2, and the intake pipe 2 is arranged at the central position of the separation tank 1. The lower end of the intake pipe 2 is connected to a primary filter, which is a prior art and not shown in the figure. The primary filter can pre-treat the dust generated during the mining process and filter out large-particle dust. A filter screen 3 is clamped inside the separation tank 1, and the filter screen 3 can perform secondary filtration on the preliminarily filtered gas to achieve the purpose of secondary dust removal. It should be noted that the filter screen 3 is modularly arranged and can be quickly spliced and disassembled for subsequent replacement and cleaning.

[0036] Combined with Figures 1-9 , it further includes a counter-flushing component 4 for changing the gas direction, so that the gas with dust can collide with each other, increasing the collision frequency of dust particles and improving the dust removal efficiency. The counter-flushing component 4 includes a rotating cavity 401 arranged inside the separation tank 1. The lower end of the rotating cavity 401 is rotatably connected to the upper end of the intake pipe 2, and the rotating cavity 401 is communicated with the intake pipe 2. A plurality of groups of exhaust ports 402 are equidistantly arranged around the outer surface of the rotating cavity 401. The exhaust ports 402 are inclined. By setting the rotating cavity 401 and the exhaust ports 402, it can rotate at the upper end of the intake pipe 2 so that the gas can be sprayed out rotatably from the inside of the exhaust ports 402. It should be noted that the lower surface of the rotating cavity 401 is a concave structure, so that when the subsequent air flow acts on the lower surface of the rotating cavity 401, the air flow can be diffused again. Two groups of symmetrically arranged limiting grooves 4011 are opened on the inner top surface of the rotating cavity 401. By setting the limiting grooves 4011, it can play a guiding and limiting role.

[0037] Among them, a sealing block 403 is arranged inside the rotating cavity 401. The sealing block 403 is in an inverted conical structure and is arranged at the connection between the rotating cavity 401 and the intake pipe 2. By setting the sealing block 403, the connection between the rotating cavity 401 and the intake pipe 2 can be sealed. It should be noted that by setting the lower end of the sealing block 403 to be conical, the gas can be quickly dispersed, increasing the acting area of the gas. When the gas is introduced from the inside of the intake pipe 2, the sealing block 403 can be lifted. A plurality of groups of driving blades 404 are equidistantly installed on the surface of the sealing block 403. By setting the driving blades 404, when the sealing block 403 is lifted by the air flow, the dispersed air flow will act on the driving blades 404, causing the driving blades 404 to drive the sealing block 403 to rotate.

[0038] Among them, a vertical rod 405 is fixedly installed at the upper end of the sealing block 403. The upper end of the vertical rod 405 passes through the inside of the rotating cavity 401 and extends to the outside. By setting the vertical rod 405, it can play a role in guiding and limiting, ensuring that the sealing block 403 can rise and fall normally; two groups of limiting blocks 4051 are symmetrically installed on the surface of the vertical rod 405. In the initial state, the limiting blocks 4051 are located directly below the limiting grooves 4011, and the limiting blocks 4051 are in plug-in fit with the limiting grooves 4011. By setting the limiting blocks 4051, and through the plug-in fit between them and the limiting grooves 4011, when the driving blade 404 rotates under the action of air flow, the rotating cavity 401 can be driven to rotate synchronously through the vertical rod 405 and the limiting blocks 4051, so that the gas can be ejected from the rotating exhaust port 402.

[0039] Among them, two groups of round rods 406 are symmetrically installed on the lower surface of the rotating cavity 401. By setting the round rods 406, it can play a role in connection and can also rotate synchronously with the rotating cavity 401; the lower ends of the two groups of round rods 406 are fixedly connected with fan blades 407, and the fan blades 407 are rotatably sleeved on the surface of the intake pipe 2. By setting the fan blades 407, they can rotate synchronously with the rotating cavity 401, blowing the air flow below upward, increasing the collision frequency of dust in the gas, and improving the dust removal efficiency; it should be noted that during the rotation of the fan blades 407, they only blow the air flow upward.

[0040] Combined with Figures 1-9 , it further includes a water mist assembly 5 for dust reduction, which can spray water mist at the inner top of the separation tank 1 to improve the dust removal efficiency; the water mist assembly 5 includes a water spraying cavity 501 arranged above the rotating cavity 401. The inside of the water spraying cavity 501 is communicated with the water injection port 102, and the water spraying cavity 501 is sleeved on the surface of the vertical rod 405. By setting the water spraying cavity 501, it can store the water source for dust reduction; it should be noted that a plurality of water spraying ports communicated with its inside are equidistantly arranged on the surface of the water spraying cavity 501, so that the water source inside the water spraying cavity 501 can be ejected to form water mist, playing a role in dust reduction.

[0041] Among them, a fitting groove 5011 is formed on the inner top surface of the water spraying cavity 501. By providing the fitting groove 5011, it can be inserted and fitted with other components. A convex block 502 is arranged inside the water spraying cavity 501, and the lower end of the convex block 502 is fixedly connected to the upper end of the vertical rod 405. By providing the convex block 502, it can move synchronously with the vertical rod 405. An insertion rod 503 is fixedly installed at the upper end of the convex block 502. The insertion rod 503 is located directly below the fitting groove 5011, and the insertion rod 503 is inserted and fitted with the fitting groove 5011. By providing the insertion rod 503, it can move synchronously with the convex block 502 and can be inserted and fitted with the fitting groove 5011, so that when the vertical rod 405 rotates, it can drive the water spraying cavity 501 to rotate synchronously. Transverse rods 504 are symmetrically installed on the surface of the convex block 502, and the ends of the transverse rods 504 are fixedly connected to a sealing ring 505. By providing the transverse rods 504 and the sealing ring 505, when the convex block 502 moves upward, it will drive the sealing ring 505 to rise through the transverse rods 504, opening the water spraying holes formed on the surface of the water spraying cavity 501, so as to achieve the purpose of dust reduction. It should be noted that the water spraying holes are sealed in the initial state of the vertical rod 405.

[0042] Combined with Figure 1 and Figure 9 , it further includes a cleaning member 6 for scraping the inner wall of the filter screen 3, so that the mixture of water mist and dust adhering to the inner wall of the filter screen 3 can be scraped off, avoiding the blockage of the filter screen 3 and prolonging the service life of the filter screen 3. The cleaning member 6 includes a rotating ring 601 rotatably sleeved on the surface of the air inlet pipe 2. The rotating ring 601 is located directly below the fan blade 407, and the rotating ring 601 is fixedly connected to the lower end of the fan blade 407 through a connecting rod. By providing the rotating ring 601, it can rotate synchronously under the action of the fan blade 407. Two groups of symmetrically arranged scraping plates 602 are fixedly installed on the surface of the rotating ring 601, and the scraping plates 602 are in contact with the inner bottom surface of the separation tank 1. By providing the scraping plates 602, they can continuously rotate on the inner bottom surface of the separation tank 1 to stir the mixture of dust and water mist accumulated on the inner bottom surface of the separation tank 1, avoiding sticking to the inner bottom surface of the separation tank 1 and affecting subsequent cleaning.

[0043] Among them, cleaning strips 603 are fixedly connected to the mutually remote ends of the two groups of scraping plates 602. The cleaning strips 603 are spirally arranged, and one side of the cleaning strips 603 is in contact with the inner wall of the filter screen 3. By providing the cleaning strips 603, when the scraping plates 602 rotate, they can rotate synchronously to scrape the mixture of water mist and dust falling on the inner wall of the filter screen 3. It should be noted that by spirally arranging the filter screen 3, when the cleaning strips 603 rotate clockwise, the scraped mixture can be concentrated on the inner bottom surface of the separation tank 1, facilitating subsequent centralized cleaning.

[0044] Specifically, when the device is in use, the gas with dust is first filtered by the primary filtering device, and then introduced from the lower end of the intake pipe 2 and acts on the lower surface of the sealing block 403, so that the sealing block 403 drives the vertical rod 405 to rise synchronously, and the limiting block 4051 enters the inside of the limiting groove 4011. When the sealing block 403 is lifted by the air flow, the air flow will enter the inside of the rotating cavity 401 and act on the driving blade 404, so that the driving blade 404 can drive the sealing block 403 to rotate. At the same time, through the cooperation of the limiting block 4051 and the limiting groove 4011, the rotating cavity 401 also starts to rotate, and the gas is rotated and discharged. When the rotating cavity 401 rotates, it will drive the fan blade 407 to rotate synchronously through the round rod 406, so that the air flow below the inside of the separation tank 1 flows upward under the action of the fan blade 407 and collides with the air flow discharged at the exhaust port 402, increasing the collision frequency of dust particles, thereby improving the dust removal efficiency;

[0045] While the vertical rod 405 is rising, it will drive the insertion rod 503 installed at the upper end of the convex block 502 to move synchronously and enter the inside of the mating groove 5011 to form an insertion connection. At the same time, the convex block 502 will also drive the sealing ring 505 that seals the water spraying port to move upward synchronously through the cross bar 504, so that while the water spraying cavity 501 rotates, it sprays water mist to settle the dust in the air flow; And while the fan blade 407 is rotating, it will drive the rotating ring 601 to rotate synchronously. The rotating rotating ring 601 will drive the cleaning strip 603 and the cleaning strip 603 to rotate synchronously, so that the cleaning strip 603 scrapes the mixture of water mist and dust on the inner wall of the filter screen 3 and concentrates it on the inner bottom surface of the separation tank 1. At the same time, cooperating with the rotating scraper 602, it ensures that the mixture does not stick to the inner bottom surface of the separation tank 1, facilitating subsequent cleaning.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
