Description

Technical Field

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

[0002] Coal preparation typically refers to the process of removing impurities from raw coal through physical or chemical methods to improve coal quality and meet the needs of different industrial applications. It is a key link in the efficient utilization and clean production of coal resources.

[0003] High concentrations of coal dust are easily generated during the crushing, screening, and conveying processes in coal preparation plants. When the concentration suspended in the air reaches a certain range and encounters open flame or high temperature, it may cause an explosion. Cyclone dust collectors are usually used to separate the dust by using centrifugal force generated by their rotation.

[0004] Through long-term observation, it has been found that when existing dust collectors process coal dust with high humidity, some dust will continuously adhere to the inner wall of the air inlet of the dust collector. Over time, dust accumulation will block the air inlet, resulting in a reduction in the effective ventilation area of ​​the air inlet. Therefore, a coal preparation dust removal device is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figure 1-5As shown, a coal preparation dust removal device includes a mounting frame 1; a dust collector 11 is fixedly connected to the top of the mounting frame 1; a motor 12 is mounted on the top of the dust collector 11; an air inlet 13 is fixedly connected to the middle of the dust collector 11; a rotating plate 14 is rotatably connected to the inner wall of the air inlet 13; a fixing plate 15 is fixedly connected to the outer wall of the dust collector 11; a slider 16 is slidably connected to the end of the fixing plate 15; a toothed rail 17 is fixedly connected to the end of the slider 16, and the toothed rail 17 and the rotating plate 14 are meshed; the middle of the fixing plate 15 rotates... A reciprocating screw 18 is dynamically connected to the slider 16, and the reciprocating screw 18 is threadedly connected to the slider 16; an internal toothed belt 19 is installed on the top of the reciprocating screw 18, and the other end of the internal toothed belt 19 is installed on the output end of the motor 12; multiple cutters 110 are fixedly connected to the middle of the rotating plate 14, and the cutters 110 are in contact with the inner wall of the air inlet 13; during operation, after the mounting bracket 1 is fixedly installed in the designated working area, the motor 12 is turned on, thereby generating suction, so that the air inlet 13 can draw external dust towards the dust collector 1. The air is transferred within 13 and then discharged again. When the motor 12 is working, its output end can drive the internal toothed belt 19 to move, so that the reciprocating screw 18 rotates. During this process, the slider 16, which is threadedly connected to the reciprocating screw 18, can gradually move upward in the middle, and then move downward again after reaching the top. This allows the toothed rail 17 to drive the rotating plate 14 to reciprocate at the inner wall of the air inlet 13. Together with the cutter 110, it removes the clumps of impurities attached to the inner wall of the air inlet 13, and in conjunction with the generated... The suction force cleans the removed impurities into the interior of the dust collector 11. This step, in conjunction with the cutter 110, can improve the cleanliness of the inner wall of the air inlet 13, reducing the problem of high-humidity coal dust being processed and adsorbed on the inner wall of the air inlet 13, which can cause the air inlet 13 to narrow over time due to agglomeration. This improves the precision of dust processing and slows down the long-term corrosion of the inner wall of the air inlet 13 by impurities. Furthermore, under the action of the internal toothed belt 19, the synchronization of the movement of the dust collector 11 and the rotating plate 14 can be improved.

[0026] like Figure 1-5As shown, a fixed frame 2 is fixedly connected to the middle of the cutter 110; a limiting plate 21 is fixedly connected to the end of the fixed frame 2; a counterweight 22 is slidably connected to the middle of the fixed frame 2; a frame plate 23 is fixedly connected to the middle of multiple sets of limiting plates 21; a shielding net 24 is fixedly connected to the inner wall of the frame plate 23; during operation, by setting the fixed frame 2 in the middle of the cutter 110, the unfolded frame plate 23 can intercept some of the incoming garbage and impurities, and when the cutter 110 continues to rotate to the top or bottom, under the action of the downward gravity of the counterweight 22, it can impact the cutter 110 or the limiting plate 2. In the middle, a vibration force is generated, and impurities on the surface of the cutter 110 are processed. The cleaned impurities are then transferred to the inner wall of the dust collector 11. This step, under the impact of the counterweight 22, can improve the cleanliness of the cutter 110 surface, improve the self-cleaning effect of the cutter 110, and reduce the problem of a lot of impurities remaining on the surface of the cutter 110, which would lead to poor cleaning effect when cleaning the inner wall of the air inlet 13. The shielding net 24 can reduce the amount of external impurities transferred to the air inlet 13 or the inner wall of the dust collector 11, which would cause them to become entangled and difficult to handle.

[0027] like Figure 1-5 As shown, a fixing member 3 is fixedly connected to the bottom of the reciprocating screw 18; a rotating ball 31 is rotatably connected to the bottom of the fixing member 3; a counterweight 32 is fixedly connected to the bottom of the rotating ball 31, and the rotating ball 31 is offset at the bottom of the fixing member 3; during operation, the fixing member 3 is provided at the bottom of the reciprocating screw 18, and when the reciprocating screw 18 rotates, it can simultaneously drive the fixing member 3 to rotate, so that the rotating ball 31 can tilt to both sides under the action of centrifugal force, and together with the counterweight 32, it impacts the inner wall area of ​​the nearby toothed rail 17, vibrating and cleaning some impurities on the surface of the toothed rail 17. This step, under the action of rotating the counterweight 32, can improve the cleanliness of the surface of the toothed rail 17, and with the offset feature of the rotating ball 31, it can increase the tilting amplitude of the counterweight 32, reducing the problem of more impurities on the surface of the toothed rail 17, which would lead to greater wear when meshing with the rotating plate 14.

[0028] like Figure 1-5 As shown, multiple sets of support members 4 are fixed to the outer wall of the rotating plate 14; a support plate 41 is fixed to the end of the support member 4; a rubber plate 42 is fixed to the side wall of the support plate 41, and the rubber plate 42 is arc-shaped. During operation, by setting multiple sets of support members 4 on the top of the rotating plate 14 to support the support plate 41, and cooperating with the arc-shaped rubber plate 42, the unfolded rubber plate 42 can protect and shield the surface of the rotating plate 14. Under the action of the support plate 41 and the rubber plate 42, this step can shield some dust near the rotating plate 14, thereby achieving a protective effect and further reducing the resistance and wear generated when the rotating plate 14 meshes with the gear rail 17.

[0029] like Figure 1-5 As shown, a housing 5 is fixedly connected to the top of the slider 16; a sponge 51 is fixedly connected to the inner wall of the housing 5, and the sponge 51 is in contact with the reciprocating screw 18; during operation, by providing the housing 5 on the top of the slider 16, the operator can pour an appropriate amount of lubricating oil into the inner wall of the sponge 51, which will be absorbed inside the sponge 51. When the reciprocating screw 18 rotates, the sponge 51 can apply an appropriate amount of lubricating oil to the surface of the reciprocating screw 18. This step, under the action of the housing 5, can reduce the wear generated when the reciprocating screw 18 and the slider 16 rotate, and reduce the abnormal noise generated when the reciprocating screw 18 and the slider 16 move.

[0030] like Figure 1-5 As shown, a protective pad 6 is fixedly connected to the middle of the counterweight 22. During operation, by providing a protective pad 6 on the surface of the counterweight 22, when the counterweight 22 approaches the cutter 110 and the limiting plate 21, the protective pad 6 can make contact with the two before the counterweight 22. This step, under the action of the protective pad 6, facilitates subsequent maintenance work and reduces direct wear on the counterweight 22.

[0031] Working principle: After the mounting bracket 1 is fixedly installed in the designated working area and the motor 12 is turned on, suction is generated, which allows the air inlet 13 to transfer external dust into the dust collector 11 and then discharge it again. When the motor 12 is working, its output end can drive the internal toothed belt 19 to move, so that the reciprocating screw 18 rotates. During this process, the slider 16, which is threadedly connected to the reciprocating screw 18, can gradually move upward in the middle, and then move downward again after reaching the top. This allows the toothed rail 17 to drive the rotating plate 14 to move in the middle. The air inlet 13 rotates reciprocally on its inner wall, and the cutter 110 removes the clumps of impurities adhering to the inner wall of the air inlet 13. The resulting suction then cleans the removed impurities into the dust collector 11. A fixing frame 2 is provided in the middle of the cutter 110, allowing the unfolded frame plate 23 to intercept some of the incoming debris. When the cutter 110 rotates to its highest or lowest position, the counterweight 22, under the influence of gravity, impacts the cutter 110 or the middle of the limiting plate 21, generating vibration. This vibration also affects the cutter 110. 10. Surface impurities are treated and transferred back to the inner wall of the dust collector 11. A fixing member 3 is provided at the bottom of the reciprocating screw 18. When the reciprocating screw 18 rotates, it simultaneously drives the fixing member 3 to rotate, causing the rotating ball 31 to tilt to both sides under the action of centrifugal force. Combined with the counterweight 32 impacting the nearby inner wall area of ​​the toothed rail 17, some impurities on the surface of the toothed rail 17 are vibrated and cleaned. Multiple sets of support members 4 are provided at the top of the rotating plate 14 to support the support plate 41, in conjunction with the arc-shaped... The rubber plate 42 allows the unfolded rubber plate 42 to protect and shield the surface of the rotating plate 14. A housing 5 is provided on the top of the slider 16, and the subsequent workers can pour an appropriate amount of lubricating oil into the inner wall of the sponge 51 and absorb it inside the sponge 51. When the reciprocating screw 18 rotates, the sponge 51 can apply an appropriate amount of lubricating oil to the surface of the reciprocating screw 18. By providing a protective pad 6 on the surface of the counterweight 22, when the counterweight 22 is close to the cutter 110 and the limiting plate 21, the protective pad 6 can make contact with the two before the counterweight 22.

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.
