Description

Technical Field

[0001] The utility model relates to the technical field of pulverized coal dust removal, in particular to a pulverized coal dust removal device facilitating disassembly and assembly of a filter screen. Background Art

[0002] In the coal mine operation environment, pulverized coal is suspended in the air. Long-term inhalation will cause serious impacts on the respiratory systems and health of workers, and may lead to various occupational diseases; too much pulverized coal will not only adhere to machinery and equipment, affecting the normal operation of the equipment and reducing production efficiency, but also when the concentration reaches a certain level, it may cause explosion or fire when encountering open fire or high temperature. At the same time, the discharge of pulverized coal into the atmosphere will cause environmental pollution and affect air quality. Therefore, the pulverized coal dust removal technology is essential. In the existing technology, in the existing pulverized coal dust removal system, due to the large workload, the replacement and maintenance of the filter screen are relatively frequent. In most pulverized coal dust removal systems, due to the long-term use of the filter screen, when disassembling and installing the filter screen, there is sometimes a jamming phenomenon during disassembly and installation, so the installation and disassembly are rather troublesome. At the same time, there is a problem that the sealing performance of the device is poor after installation.

[0003] Currently, the prior art CN 210768883 U discloses an efficient coal mine dust removal device, which relates to the technical field of coal mine dust removal, and includes a housing. One end of the dust collector inlet pipe far from the air suction pump housing is fixedly connected with a dust collector. A dust collection box is arranged below the dust collector. The lower end of the first water delivery pipe is fixedly connected with a spray disc. A suction and delivery pump is fixedly connected to one side of the spray cylinder. A sprayer is arranged on one side of the second filter screen. A liquid storage tank is arranged on one side of the second water delivery pipe. By setting the dust collector in the utility model, the maintenance and management are convenient, the air volume to be treated is large, and the dust removal efficiency is high. By setting the sprayer and the liquid storage tank, a dust settling agent is added to the spray. After the dust particles are combined with the water mist, they settle quickly, reducing the water consumption of the sprayer and not easily causing water accumulation in the mine. By setting the spray box, the dust is purified twice, and the dust removal and purification effect is good. The pulverized coal in the sewage can be recycled.

The number of second springs 17 are respectively fixedly connected to the pressing plate and the dust removal box 4. The pressing plate abuts against the card block 11.

[0038] As Figure 3 shown, the filter screen installation mechanism 2 includes: a filter screen installation base 6 provided on the sliding groove, a number of filter screens 7 provided on the filter screen installation base 6, and a rotating card block assembly 8 provided on the filter screen installation base 6. The filter screen installation base 6 is provided directly below the air outlet 18 of the air suction pump. A number of linear slide rails 16 are symmetrically distributed on both sides of the filter screen installation base 6. The linear slide rails 16 are respectively fixedly connected to the filter screen installation base 6 and the sliding groove.

[0039] A first trapezoidal groove is provided on the filter screen installation base 6. A number of filter screens 7 are provided directly above the first trapezoidal groove. The number of filter screens 7 abut against the first trapezoidal groove. Further, a second trapezoidal groove opening is provided on the upper surface of the number of filter screens 7, and a trapezoidal frame is provided on the lower surface. The trapezoidal frames respectively correspond to the first trapezoidal groove opening and the second trapezoidal groove opening.

[0040] As Figure 4 , Figure 5 , Figure 6 shown, the rotating card block assembly 8 includes: a mounting block 9 provided on the filter screen installation base 6, a rotating rod 10 sleeved on the mounting block 9, and a card block 11 connected to the rotating rod 10.

[0041] A limiting ring 12 and a sliding ring 13 are respectively provided on the mounting block 9. The limiting ring 12 and the sliding ring 13 are respectively sleeved on the outer surface of the rotating rod 10. The limiting ring 12 and the sliding ring 13 are respectively fixedly connected to the mounting block 9.

[0042] A number of sliding rods 14 are symmetrically distributed at one end of the rotating rod 10. The sliding rods 14 are fixedly connected to the rotating rod 10. A first spring 15 is provided on the rotating rod 10. The first spring 15 is sleeved inside the sliding ring 13, fixedly connected to the rotating rod 10 at one end, and abuts against the mounting block 9 at the other end.

[0043] A number of guide grooves are arrayed on the sliding ring 13. A first inclined surface is distributed on the guide grooves. A number of limiting grooves are arrayed on the limiting ring 12. A second inclined surface is distributed on the limiting grooves.

[0044] An air outlet 18 is provided on the side surface of the collection mechanism 3 and is communicated with the inside of the collection box.

[0045] When installing the filter screen of the present utility model, the adjusting block is adjusted to be in a flat state, and the filter screen installation base 6 is pushed inward. The filter screen installation base 6 moves along the linear slide rail 16. After the clamping plate abuts against the abutting plate, it is continuously pushed into the dust removal box 4, and the abutting plate compresses the second spring 17. At the same time, the block 11 is acted upon by the abutting plate, the rotating rod 10 compresses the first spring 15, and the sliding rod 14 on the rotating rod 10 disengages from the bottom of the first limiting groove on the limiting ring 12 and then touches the first inclined surface on the sliding ring 13. At this time, the block enters the cylindrical card slot. As the first spring 15 is further compressed, the sliding rod 14 slides along the first inclined surface to the bottom of the guiding groove and is clamped tightly, and the rotating rod rotates by a certain angle. The filter screen installation base 6 is released, and the rotating rod 10 is reset under the elastic force of the first spring 15, and the sliding rod 14 touches the inclined surface of the second limiting groove adjacent to the first limiting groove of the limiting ring 12. The elastic force of the first spring 15 continues to be released, forcing the sliding rod 14 to move along the inclined surface of the second limiting groove to the bottom of the second limiting groove and be clamped tightly again, and the rotating rod rotates by a certain angle again. Thus, the sliding rod 14 completes the process of switching from one limiting groove on the limiting ring 12 to another limiting groove, and the rotating rod 10 also rotates 90° accordingly. Therefore, the block 11 connected to the rotating rod 10 rotates 90° in the cylindrical card slot under the drive of the rotating rod 10 at the same time, and the block stands up. At the same time, the elastic force of the compressed second spring 17 is released, pushing the abutting plate to slide outward, and at the same time pushing the erected block 11 to slide to the bottom surface of the cylindrical card slot. The block 11 abuts against the cylindrical card slot. Therefore, the block 11 is pressed tightly against the bottom surface of the cylindrical card slot by the abutting plate under the elastic force of the second spring 17 and cannot be separated, achieving the purpose of fixing the filter screen installation base 6.

[0046] When the filter screen needs to be replaced, only need to push the filter screen installation base 6 inward again, and the above-mentioned moving parts will repeat the above actions, forcing the block 11 to rotate 90° again to the flat state during installation. At this time, the block 11 disengages from the cylindrical card slot under the thrust of the second spring, and continues to move outward under the push of the abutting plate, thereby pushing the entire filter screen installation base 6 to move along the linear slide rail 16 for easy removal.

[0047] Based on the ideal embodiments of the present utility model as inspiration, through the above description, relevant personnel can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
