[0018] Beneficial effects

Based on the action of centrifugal force and gravity, the rotating airflow separates the dust particles in the flue gas through the one-way filter screen, so that the dust particles in the flue gas are discharged through the dust outlet, thereby realizing flue gas dust removal, and solving the technical problem that the flue gas generated in the existing medium density fiberboard production workshop contains a large amount of dust, and directly discharging it into the atmosphere will cause a large amount of pollution, and thus the air pollution problem caused by the medium density fiberboard production workshop.

[0021] 2. For the main flue gas cyclone dust collector for medium density fiberboard production in a workshop, by setting a purification mechanism, driving the electric slide rail to drive the frame plate to move towards the direction close to the first driving rod, the first U-shaped plate in the first air duct completely moves out of the first air duct and the first U-shaped plate inside the support housing completely moves into the first air duct, thereby realizing the replacement of the activated carbon in the first air duct.

[0022] 3.

[0044] The present invention will be further described below with reference to the embodiments.

[0045] Embodiment 1

[0046] Please refer to Figure 1 - Figure 2 , a main flue gas cyclone dust collector for medium density fiberboard production workshop, including a workbench 1. An exhaust pump 11 is fixedly installed on the top of the workbench 1. The output end of the exhaust pump 11 is fixedly communicated with an exhaust passage 12. A support plate 13 is fixedly connected to the top of the workbench 1.

[0047] A cyclone dust removal mechanism 2 is arranged on one side of the workbench 1. The cyclone dust removal mechanism 2 includes a support frame 21, a circular ring sleeve 22, a cyclone dust removal box 23, an air inlet 24, an air outlet 25, a dust outlet 26, a sealing box 27, a motor 28, a cyclone rod 29, a cyclone fan blade 210, a one-way filter screen 211, and a top cover 212.

[0048] A circular ring sleeve 22 is arranged on the top of the support frame 21. The outer side wall of the cyclone dust removal box 23 is embedded and fixed inside the circular ring sleeve 22. The cyclone dust removal box 23 is set as an inverted conical barrel structure. An air inlet 24 is arranged on the side wall of the cyclone dust removal box 23. An air outlet 25 and a dust outlet 26 are respectively arranged at the upper and lower ends of the cyclone dust removal box 23. Air blowing fans are arranged at both the air inlet 24 and the air outlet 25, which can effectively increase the pressure when the gas passes through and effectively improve the efficiency of waste gas treatment.

[0049] A sealing box 27 is fixedly connected inside the dust outlet 26. A motor 28 is fixedly installed inside the sealing box 27. The top of the output shaft of the motor 28 movably penetrates through the sealing box 27 and is fixedly connected to the bottom of the cyclone rod 29. The motor 28 drives the cyclone rod 29 to rotate. A plurality of cyclone fan blades 210 are fixedly connected to the outer circumferential surface of the cyclone rod 29.

[0050] The top cover 212 of the cyclone dust removal box 23 is set in an arc-shaped horn structure, which can effectively prevent the flue gas from accumulating and staying at the top of the cyclone dust removal box 23 when rising and discharging, effectively reducing the resistance when the flue gas is discharged, improving the smoothness of exhaust, and greatly improving the dust removal efficiency.

[0051] To sum up, by setting the device of the present invention in the medium density fiberboard production workshop, the flue gas generated in the medium density fiberboard production workshop enters the cyclone dust removal box 23 through the air inlet 24. The motor 28 is started to drive the cyclone rod 29 to rotate, and then drive the cyclone fan blade 210 to rotate, thereby generating a rotating air flow. Based on the action of centrifugal force and gravity, the rotating air flow separates the dust particles in the flue gas through the one-way filter screen 211, so that the dust particles in the flue gas are discharged through the dust outlet 26, thereby realizing flue gas dust removal, and solving the technical problem that a large amount of dust is contained in the flue gas generated in the existing medium density fiberboard production workshop, and directly discharging it into the atmosphere will cause a large amount of pollution, and thus the air pollution problem caused by the medium density fiberboard production workshop.

[0068] A collection box 75 is fixedly connected to the outside of the air guiding pipe two 72, and the top of the collection box 75 is open. A support housing 76 is fixedly connected to one side of the air guiding pipe one 71. The top and the side close to the air guiding pipe one 71 of the support housing 76 are both open. The inner bottom surface of the support housing 76 and the inner bottom surface of the end of the air guiding pipe one 71 away from the air outlet 25 are coplanar. A through groove three 77 is opened at the bottom of the support housing 76. An electric telescopic rod 78 is fixedly installed at the bottom of the support housing 76. The electric telescopic rod 78 is vertically arranged and the output end faces downwards. The output end of the electric telescopic rod 78 is fixedly connected with a vertical plate 79 through a cross plate. The vertical plate 79 movably passes through the through groove three 77. The electric telescopic rod 78 is a prior art and will not be elaborated in this solution.

[0069] All other structures are the same as those in the first embodiment.

[0070] The flue gas generated in the medium density fiberboard production workshop also contains pollutants such as organic matter, sulfides, and nitrides. The dust particles in the flue gas are separated by a one-way filter screen 211 using a rotating airflow. The flue gas after cyclone dust removal still contains pollutants such as organic matter, sulfides, and nitrides. Therefore, at this time, the adsorption effect of adsorbents such as activated carbon can be utilized to adsorb the harmful substances in the flue gas on the surface of the adsorbent, thereby realizing the separation and removal of pollutants. Activated carbon has a large specific surface area and good adsorption performance, and can effectively remove pollutants such as organic matter, sulfides, and nitrides in the waste gas. Since activated carbon can be recycled, when replacing it, it is necessary to first disassemble the activated carbon adsorber (including the subsequent loading and reinstallation of the activated carbon) before further replacement, and the overall operation is cumbersome. Therefore, the main flue gas cyclone dust collector for medium density fiberboard production in the present invention solves the above problems.

[0071] The working principle and usage process of the embodiment of the present invention:

[0072] There is a separation part 6 inside the first guide pipe 71, and there is a separation part 6 inside the support housing 76. The filter spaces 64 of the two separation parts 6 are filled with activated carbon. The magnetic plate three 610 on the separation part 6 inside the first guide pipe 71 is in close magnetic contact with the magnetic plate two 68 on the separation part 6 inside the support housing 76.

[0073] The flue gas after cyclone dust removal flows through the air outlet 25 to the first guide pipe 71. The flue gas after cyclone dust removal first enters the filter space 64 through the filter holes of the first filter plate 62. Pollutants such as organic matter, sulfides, and nitrides in the flue gas after cyclone dust removal are adsorbed on the surface of the activated carbon, thereby realizing the separation and removal of pollutants. Then, the flue gas after dust removal and decontamination enters the air guide space 65 through the filter holes of the second filter plate 63. Next, the flue gas after dust removal and decontamination flows through the second through groove 74 into the second guide pipe 72. Finally, under the action of the exhaust pump 11, the flue gas after dust removal and decontamination is discharged through the exhaust passage 12, realizing the dust removal and decontamination of the flue gas, realizing the purification of the flue gas, and effectively improving the purity of flue gas treatment.

[0074] After the activated carbon in the filter space 64 is adsorbed for a long time, it is necessary to replace the saturated activated carbon after use (it can be recycled); first, drive the electric telescopic rod 78 from the shortest to the longest, so that the top of the vertical plate 79 is coplanar with the inner bottom surface of the support housing 76, and the gap between the vertical plate 79 and the inner wall of the third through groove 77 is small, and the activated carbon cannot pass through the gap between the vertical plate 79 and the inner wall of the third through groove 77.

[0075] Then, drive the electric slide rail 42 to drive the frame plate 51 to move from the support housing 76 towards the direction close to the first driving rod 43, so that the first sphere 511 rolls on the surface of the positioning plate 45 (at this time, the second spring 510 is compressed), and then the limiting rod 57 moves to the connection hole 612 and the limiting rod 57 is facing the connection hole 612. At this time, due to the magnetic attraction of the fourth magnetic plate 613, the first magnetic plate 58 contacts the fourth magnetic plate 613, and then the limiting rod 57 is inserted into the connection hole 612 (at this time, the second spring 510 is further compressed), and then the limiting rod 57 is tightly connected to the connecting plate 611 to form a whole;

[0076] Next, continue to drive the electric slide rail 42 to drive the frame plate 51 to move towards the direction close to the first driving rod 43. At this time, the first U-shaped plate 61 in the first air duct 71 moves towards the outside of the first air duct 71 through the first through groove 73. The used and saturated activated carbon in the filtering space 64 just falls into the collection box 75 under the action of gravity, and the unloading of the activated carbon can be completed at one time, and the automatic operation is simple and convenient; at the same time, the magnetic attraction of the third magnetic plate 610 of the separating part 6 on the inner side of the first air duct 71 to the second magnetic plate 68 of the separating part 6 on the inner side of the support housing 76 drives the separating part 6 on the inner side of the support housing 76 to move towards the inner side of the first air duct 71 (the elastic sealing ring 66 contacts the inner wall of the first air duct 71 to ensure the sealing inside the first air duct 71). Until the first U-shaped plate 61 in the first air duct 71 completely moves out of the first air duct 71 and the first U-shaped plate 61 on the inner side of the support housing 76 completely moves into the first air duct 71, the replacement of the activated carbon in the first air duct 71 is realized. Furthermore, while the used and saturated activated carbon is unloaded, fresh activated carbon can be re-added to the first air duct 71, which does not affect the continuous dust removal and decontamination treatment of the flue gas, and improves the automation degree and reliability of the device;

[0077] Next, drive the electric telescopic rod 78 to shrink to the shortest, so that the vertical plate 79 moves upward, and then the vertical plate 79 is in close contact with the inner side surface of the third U-shaped plate 69 of the separating part 6 on the inner side of the first air duct 71, so that the third U-shaped plate 69 cannot move, and then the separating part 6 on the inner side of the first air duct 71 cannot move;

[0078] Next, continue to drive the electric slide rail 42 to drive the frame plate 51 to move in the direction close to the first driving rod 43. During this process, the gear 55 will engage with the rack 411, and then the gear 55 will drive the threaded rod 52 to rotate forward together, and then the L-shaped plate 54 will move upward until the L-shaped plate 54 drives the separating part 6 to completely move above the first air guide pipe 71. At this time, one end of the first driving rod 43 contacts the misaligned plate 513. Continue to drive the electric slide rail 42 to drive the frame plate 51 to move in the direction close to the first driving rod 43. The first driving rod 43 pushes the misaligned plate 513 to shorten the second telescopic rod 512, and the second sphere 514 moves away from between the arc convex surface of the first arc plate 515 and the arc convex surface of the second arc plate 516. Then, the first arc plate 515 and the second arc plate 516 approach each other, and then the first arc plate 515 moves downward to drive the limiting plate 520 to insert into the limiting groove 413, and then the limiting plate 520 and the connecting plate 412 are tightly connected as a whole;

[0079] Then, drive the electric slide rail 42 to drive the frame plate 51 to move in the direction close to the second driving rod 44. When the frame plate 51 drives the separating part 6 to move directly above the support housing 76 (at this time, the first spring 48 is stretched), at this time, the first sphere 511 moves from the positioning plate 45 through the arc-shaped plate 46 to the inner side of the fixed frame plate 41. Due to the tension of the second spring 510, the mounting plate 59 moves in the direction away from the L-shaped plate 54, and then the mounting plate 59 drives the limiting rod 57 to be completely pulled out of the connecting hole 612. Then, the separating part 6 falls inside the support housing 76 under the action of gravity and is in close contact with the inner wall of the support housing 76. Due to the magnetic attraction of the third magnetic plate 610 of the separating part 6 inside the first air guide pipe 71 to the second magnetic plate 68 of the separating part 6 inside the support housing 76, the two separating parts 6 are firmly connected as a whole. Due to the inner wall of the support housing 76 and the vertical plate 79 at this time, the two separating parts 6 will not shake. And at this time, fresh activated carbon is added to the filtering space 64 of the separating part 6 inside the support housing 76. Thus, after the activated carbon is saturated in use, fresh activated carbon can be replaced at any time, saving the time for adding fresh activated carbon during the process of dust removal and decontamination of flue gas, without affecting the continuous dust removal and decontamination of flue gas, and further improving the automation degree and reliability of the device;

[0080] Finally, continue to drive the electric slide rail 42 to drive the frame plate 51 to move towards the direction close to the second driving rod 44 until one end of the second driving rod 44 contacts the dislocation plate 513. Then continue to drive the electric slide rail 42 to drive the frame plate 51 to move towards the direction close to the second driving rod 44. The second driving rod 44 pushes the dislocation plate 513 to extend the second telescopic rod 512, so that the second sphere 514 is inserted between the arc convex surface of the first arc plate 515 and the arc convex surface of the second arc plate 516, thereby separating the first arc plate 515 and the second arc plate 516 from each other. Further, the first arc plate 515 moves upward to drive the limiting plate 520 to be pulled out of the limiting groove 413. Further, due to the contraction force of the first spring 48, the folded plate 49 moves towards the direction close to the first driving rod 43 and resets. During the process of the folded plate 49 moving towards the direction close to the first driving rod 43, the rack 411 also moves towards the direction close to the first driving rod 43 and resets. The gear 55 will mesh with the rack 411, thereby driving the threaded rod 52 to reverse together with the gear 55, and further driving the L-shaped plate 54 to move downward and reset.

[0081] In summary, by setting the driving part 4, the moving part 5, the separating part 6, and the air guiding part 7, driving the electric slide rail 42 to drive the frame plate 51 to move towards the direction close to the first driving rod 43, the first U-shaped plate 61 in the first air guiding pipe 71 is completely moved out of the first air guiding pipe 71, and the first U-shaped plate 61 inside the supporting shell 76 is completely moved into the first air guiding pipe 71. Thus, the replacement of the activated carbon in the first air guiding pipe 71 is realized. Moreover, when the saturated activated carbon after use is unloaded, fresh activated carbon can be re-added into the first air guiding pipe 71, which does not affect the continuous dust removal and decontamination treatment of the flue gas, and improves the automation degree and reliability of the device. By driving the electric slide rail 42 to drive the frame plate 51 to move towards the direction close to the second driving rod 44, the separating part 6 falls inside the supporting shell 76 under the action of gravity and is in close contact with the inner wall of the supporting shell 76. Then, fresh activated carbon is added into the filtering space 64 of the separating part 6 inside the supporting shell 76. Thus, after the activated carbon is saturated during use, fresh activated carbon can be replaced at any time, saving the time for re-adding fresh activated carbon during the dust removal and decontamination treatment of the flue gas, and not affecting the continuous dust removal and decontamination treatment of the flue gas, further improving the automation degree and reliability of the device.
