Description

Technical Field

[0001] The present invention relates to the technical field related to pollution treatment, and in particular to a pollution treatment device for mineral processing. Background Art

[0002] Ore dressing is a process of crushing and grinding the ore according to the physical and chemical properties of different minerals in the ore, and then using gravity separation, flotation, magnetic separation, electrostatic separation and other methods to separate the useful minerals from the gangue minerals in the ore, and to separate the various symbiotic useful minerals from each other as much as possible, and to remove or reduce harmful impurities in order to obtain the raw materials required for smelting or other industries. Ore dressing can enrich the useful components in the minerals, reduce the consumption of fuel and transportation in the smelting or other processing processes, and make low-grade ores economically utilized.

[0003] At present, dust removal equipment is often used in the beneficiation of iron ore in order to deal with the large amount of smoke and dust generated during the beneficiation process. Although the existing dust removal equipment has basic dust removal functions in actual use, the existing dust removal equipment mainly uses filter screens to separate and process the floating dust particles in the gas. Although this dust removal method can remove the floating dust particles in the dust-laden gas, the filter screen will be clogged by the floating dust particles over time, which will greatly affect the filtering effect. For this reason, workshop workers are required to regularly open the filter equipment to clean the internal filter screen structure and brush off the floating dust particles adhered to the filter screen structure. This process increases the labor intensity of the workers, and when cleaning the core filter cartridge, the workers can only brush around the side of the filter cartridge to clean it, resulting in the cleaning brush being unable to clean the floating dust particles on the periphery of the filter cartridge around it, which not only reduces the cleaning effect of the filter cartridge, but also increases the workload of the workers.

The filter box is fixedly installed with an exhaust fan at the top of the side away from the dust filter, and the exhaust fan is aligned with the fan-shaped fine filter.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, in the twisting cleaning assembly, the arc-shaped movable ring is driven to perform a compound movement of lifting and rotating, thereby driving the L-shaped cleaning rod linked thereto to move synchronously, and the L-shaped cleaning rod then drives the twisting cleaning ring to rotate around the outer wall of the filter cartridge for cleaning. At the same time, the twisting cleaning brush integrated on the inner side of the twisting cleaning ring directly acts on the outer surface of the filter cartridge, and efficiently brushes and cleans the floating dust particles attached thereto. The entire cleaning process is accompanied by continuous reciprocating twisting action, which not only significantly enhances the cleaning force of the filter cartridge, but also more effectively improves the cleaning coverage and cleaning effect of the arc-shaped surface of the outer periphery of the filter cartridge, reduces the labor intensity of workers, and improves the cleaning effect of the filter cartridge.

[0017] In the present invention, the first rotating disk is driven to move by the rotating motor in the upper and lower brushing assemblies, which in turn drives the T-shaped limit ring on the first rotating disk to rotate synchronously. The T-shaped limit ring converts the rotational motion into vertical reciprocating motion of the brush rod on the limit base through the circular support ring. During the lifting process, the brush rod drives the first cleaning plate and its integrated brush cleaning brush to closely adhere to the inner side of the dust filter for efficient brushing. Synchronously, the twisting cleaning brush of the twisting cleaning ring acts synergistically on the outside of the filter cartridge to form an internal and external bidirectional cleaning force. The peeled dust particles slide along the inclined bottom of the conical discharge seat under the action of gravity, and are finally discharged through the discharge pipe at the bottom.

[0018] In the present invention, the second rotating disk in the left and right swinging components rotates in close cooperation with the swing rod, driving the arc-shaped swinging plate and the swing column to rotate and swing synchronously, and the swinging cleaning brush on the second cleaning plate is tightly attached to the fan-shaped fine filter and swings along with the swing column. The swinging cleaning brush accurately and forcefully scrapes the dust particles adhered to the fan-shaped fine filter after filtration. The particulate impurities adhered to the fan-shaped fine filter are gradually loosened under the continuous action of the swinging cleaning brush, and finally fall into the conical frame below under the action of gravity. The conical frame gathers the fallen particulate impurities, and then discharges these particles in a concentrated manner through the discharge pipes at both ends thereof, thereby achieving effective cleaning and discharge of dust particles and ensuring the cleanliness and efficient operation of the entire filter box.

[0019] In the present invention, the dust filter is used to preliminarily block and absorb the gas containing floating dust particles, and the dust filter blocks and absorbs larger floating dust particles. The blower at the bottom of the filter box is used to press and blow air into the blower seat, and the blower seat presses and blows air to the connecting pipe on the top of the filter cartridge through the air guide pipe, thereby achieving thorough cleaning of the filter cartridge and improving the filtering effect of the filter cartridge on floating dust particles.

[0020] In the present invention, the rotating plate on the fixed rotating seat synchronously drives the flip plates on the front rotating seat and the rear rotating seat to rotate. During the process of driving the flip plates to move, the rotating plate can drive the twisting cleaning ring to rotate and lift the periphery of the filter cartridge for cleaning, thereby improving the cleaning ability of the floating dust particles on the periphery of the filter cartridge, and utilizing the twisting cleaning ring with twisting rotational motion to improve the cleaning effect of the filter cartridge.

[0021] In the present invention, when the rotating plate drives the flip plate on the front rotating seat to move, the flip plate cooperates with the first rotating disk, the circular support ring and the brush rod to lift and reciprocate the first cleaning plate, and the first cleaning plate is used to thoroughly clean the dust filter. When the rotating plate drives the flip plate on the rear rotating seat to move, the flip plate cooperates with the second rotating disk, the swing column, the swing rod and the arc swing plate to drive the second cleaning plate to fully clean the fan-shaped fine filter. The back and forth swinging cleaning improves the cleaning effect, and the swinging cleaning brush will not adhere to dust and affect the cleaning ability. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting pipe 21 on the top plate 12 cooperates with the filter cartridge 20 to discharge the air containing dust particles from the outside of the dust filter 11 into the filter box 10. The dust particles will be initially blocked and absorbed by the dust filter 11. The dust filter 11 blocks and absorbs larger particles of dust particles. Then the air containing smaller dust particles passes through the filter cartridge 20 for filtration and purification. In addition, when cleaning the filter cartridge 20, the blower 14 at the bottom of the filter box 10 is used to press and blow air into the blower seat 15, and the blower seat 15 presses and blows air to the connecting pipe 21 at the top of the filter cartridge 20 through the air guide pipe 16, so as to thoroughly clean the filter cartridge 20 and improve the filtering effect of the filter cartridge 20 on dust particles.

[0046] Working principle: Place the filter box 10 at the outlet of the mineral processing equipment, and absorb and filter the dust particles generated during the mineral processing process through the filter box 10. The exhaust fan 17 in the filter box 10 generates negative pressure on the top space of the top plate 12 through the fan-shaped fine filter 59. The connecting pipe 21 on the top plate 12 cooperates with the filter cartridge 20 to discharge the air containing dust particles from the outside of the dust filter 11 into the filter box 10. First, the dust particles will be preliminarily blocked and absorbed by the dust filter 11. The dust filter 11 blocks and absorbs larger dust particles, and then the air containing smaller dust particles passes through the filter cartridge 20 for filtration and purification. The filtered and purified air is further filtered and purified through the fan-shaped fine filter 59, stably and effectively filtering and absorbing the dust particles generated by mineral processing, effectively preventing the dust particles generated by mineral processing from polluting the workshop.

[0047] The rotary plate 34 drives the T-shaped rotating rod 35 to rotate synchronously. During the movement, the T-shaped rotating rod 35 drives the curved movable plate 23 to move through the arc rotating block 36. The curved movable plate 23 synchronously drives the curved movable ring 22 outside the connecting tube 21 to move. The curved movable ring 22 also rotates around the outer periphery of the connecting tube 21 as the T-shaped rotating rod 35, the arc rotating block 36 and the rotating plate 34 rotate. During the lifting and rotating process, the curved movable ring 22 drives the twisting cleaning ring 25 to rotate and clean the outer periphery of the filter cartridge 20 through the L-shaped cleaning rod 24. The twisting cleaning brush 26 in the twisting cleaning ring 25 brushes and cleans the floating dust particles on the outer periphery of the filter cartridge 20. The back-and-forth twisting cleaning improves the cleaning effect of the outer periphery of the filter cartridge 20.

[0048] The first pulley 31, the second pulley 32 and the transmission belt 33 are used to rotate the rotating plates 34 on both sides of the inner wall of the filter box 10 synchronously. When the arc movable ring 22 is twisted and lifted, it will also drive the arc flip block 39 on the front rotating seat 40 and the rear rotating seat 50 to move synchronously through the arc movable rod. The arc flip block 39 drives the flip plate 37 on the front rotating seat 40 and the rear rotating seat 50 to move under the action of the T-shaped flip rod 38. The flip plate 37 will respectively drive the first rotating disk 42 and the second rotating disk 52 on the front rotating seat 40 and the rear rotating seat 50 to rotate. During the movement, the first rotating disk 42 drives the T-shaped limit ring 43 to rotate. The T-shaped limit ring 43 will drive the brush rod 44 on the limit base 45 to move up and down through the circular support ring 46. During the reciprocating lifting process, the brush rod 44 drives the brushing cleaning brush 47 on the first cleaning plate 41 to brush and clean the inner side of the dust filter 11;

[0049] The brushing brush 47 of the first cleaning plate 41 and the twisting cleaning brush 26 of the twisting cleaning ring 25 brush the floating dust particles down, and the floating dust particles are discharged collectively through the discharge pipe under the conical discharge seat 48 under the action of gravity;

[0050] When the flip plate 37 drives the second rotating disk 52 on the rear rotating seat 50 to rotate, the second rotating disk 52 will drive the arc-shaped swinging plate 55 and the swinging column 53 to rotate and swing synchronously through the swinging rod 54. During the back-and-forth swinging process, the swinging column 53 drives the swinging cleaning brush 56 on the second cleaning plate 51 to scrape the dust particles filtered on the fan-shaped fine filter 59. The particulate impurities adhered to the fan-shaped fine filter 59 will fall into the conical frame 57 due to gravity, and then the particles are discharged collectively through the discharge pipes 58 at both ends of the conical frame 57, which makes it simple and convenient to clean the filter inside the filter box 10.

[0051] When cleaning the filter cartridge 20, the blower 14 at the bottom of the filter box 10 is used to pressurize and blow air into the blower seat 15, and the blower seat 15 presses and blows air to the connecting pipe 21 at the top of the filter cartridge 20 through the air duct 16. The air duct 16 is in a closed state when the exhaust fan 17 is working, thereby achieving thorough cleaning of the filter cartridge 20 and improving the filtering effect of the filter cartridge 20 on floating dust particles.

[0052] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
