Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, and more specifically, to a dust removal mechanism and a bag filter dust collector for filter bags. Background Technology

[0002] A large amount of waste gas is generated when materials are sintered in the factory. This waste gas contains dust and other impurities. Generally, the impurities in the waste gas are filtered by a bag filter. The filtered air can then be discharged, leaving the impurities on the outside of the filter bag. After a period of use, the impurities on the outside of the filter bag need to be cleaned.

[0003] In existing technologies, when cleaning filter bags, high-pressure air is generally blown out through the back-blowing chamber at the top of the bag filter, and then the high-pressure air enters the inside of the filter bag, which can blow the dust on the outside of the filter bag into the hopper below. However, there are some problems in its use. After long-term use, and because some dust contains a certain amount of moisture, the dust on the outside of the filter bag sticks together quite well, and the dust removal effect by high-pressure air alone is not good. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that high-pressure air alone is not effective for dust removal of filter bags, and to design a dust removal mechanism and filter bag dust collector for filter bags.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: a dust removal mechanism for filter bags, comprising a holding platform with multiple circular holes, a filter bag installed at each circular hole, a supporting steel cage placed inside the filter bag, a lifting platform below the holding platform with multiple cleaning ports fitted onto the outside of the filter bag, a cleaning brush installed inside the cleaning port, a drive frame below the lifting platform that can move the lifting platform up and down, a pressing platform at the top of the holding platform with multiple air inlets corresponding to the circular holes and located above the circular holes, and a transmission frame installed on the holding platform. When the lifting platform moves up and down, the transmission frame can drive the pressing platform to move up and down. When the lifting platform moves downward, it can push the supporting steel cage downward.

[0006] Furthermore, the drive frame includes four screw jacks located below the serving platform. The four screw jacks are driven to rotate by a power component. A transmission screw is installed at the output end of the screw jack. Threaded holes are opened at the four corners of the lifting platform. The transmission screw and the threaded holes are connected by threads. Multiple clearance openings are opened on the serving platform. The clearance openings correspond one-to-one with the threaded holes and are located above the threaded holes. A protective box is installed at the upper end of the clearance opening. A rolling bearing is installed at the upper end of the transmission screw. The upper end of the rolling bearing is installed on the upper surface inside the protective box.

[0007] Furthermore, the lifting platform has multiple limiting holes, and a limiting rod is provided in the limiting hole. The upper end of the limiting rod is fixedly connected to the lower surface of the serving platform.

[0008] Furthermore, a first telescopic dust cover is installed at the upper end of the threaded hole. The upper end of the first telescopic dust cover extends through the clearance opening into the protective box and is connected to the inner surface of the protective box. A second telescopic dust cover is installed at the lower end of the threaded hole. The lower end of the second telescopic dust cover is connected to the upper end of the screw jack. The first telescopic dust cover and the second telescopic dust cover can cover the transmission screw.

[0009] Furthermore, both the first and second telescopic dust covers are circular accordion-style dust covers.

[0010] Furthermore, the transmission frame includes a circular lifting plate installed above the inner side of the first telescopic dust cover. A pressing rod is installed on the upper end of the circular lifting plate. An inlet and outlet are opened at the upper end of the protective box. Multiple limiting platforms are installed on both sides of the pressing platform. One end of the pressing rod passes through the inlet and outlet and extends above the limiting platform. A positioning hole is opened on one side of the limiting platform. A first spring rod is installed on the protective box on one side of the positioning hole. A pulley is installed on the telescopic end of the first spring rod. One end of the pulley abuts against the side surface of the limiting platform. The pressing platform is connected to the holding platform through multiple second spring rods. A support plate is installed on the outside of the supporting steel cage. Multiple third spring rods are installed on the lower end of the support plate. Multiple elastic pads are installed on the upper end of the support plate. When the pressing platform moves downward, the supporting steel cage can be pushed downward through the support plate. Multiple push rods are installed on the lifting platform on the outside of the threaded hole. The upper end of the push rod can contact the lower end of the circular lifting plate. Multiple guide holes are opened on the circular lifting plate. Guide rods are installed in the guide holes. The upper end of the guide rods contacts the inner surface of the protective box. A reset frame is installed on the pressing rod. The reset frame resets the first spring rod.

[0011] Furthermore, the reset frame includes a reset plate installed at the lower end of the pressing rod, a first rotating roller installed at the lower end of the reset plate, a rotating plate installed on the first rotating roller, a fixed rod installed on the reset plate on one side above the first rotating roller, a fixed plate installed on the other side above the first rotating roller, the fixed plate and the rotating plate are connected by a telescopic spring, the telescopic spring can push the rotating plate onto the fixed rod, and a second rotating roller installed on one side of the first spring rod is provided below the rotating plate.

[0012] Furthermore, the power component includes a dual-shaft output motor, the two output ends of which are connected to a reducer via a transmission shaft. The reducer has two output ends, which are respectively connected to the input ends of two screw jacks via transmission rods.

[0013] Furthermore, dustproof boxes are installed on the outside of the dual-shaft output motor, reducer, and screw jack. Rotary sealing treatment is applied to the intersection of the dustproof boxes and the input and output ends of the dual-shaft output motor, reducer, and screw jack. The dustproof boxes are installed on the upper end of the hopper of the bag filter.

[0014] A bag filter dust collector, wherein the holding platform is installed on the upper side of the filter box of the bag filter dust collector.

[0015] The beneficial effects of this invention are as follows: Before using high-pressure air to remove dust from the filter bags, the lifting platform and cleaning brush are moved downwards by the drive frame to initially clean the dust on the outside of the filter bags. When the lifting platform moves downwards, the supporting steel cage is pushed downwards by the pressing platform to support the lower end of the filter bags. Then, the lifting platform and cleaning brush are moved upwards by the drive frame to clean the filter bags again and fix the lower end of the filter bags. This prevents the filter bags from wrinkling when the lifting platform moves upwards, thus affecting the dust removal effect. After dust removal is completed, the pressing platform no longer pushes the supporting steel cage downwards, thereby reducing the force between the supporting steel cage and the filter bags and extending the service life of the filter bags.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] This invention provides, for example Figure 1-6The dust collection mechanism for filter bags shown includes a holding platform 1 with multiple round holes 2. Filter bags 3 are installed at the round holes 2, and a supporting steel cage 4 is placed inside the filter bags 3. A lifting platform 5 is provided below the holding platform 1, with multiple cleaning ports 6. The cleaning ports 6 are fitted onto the outside of the filter bags 3, and cleaning brushes 7 are installed inside the cleaning ports 6. A drive frame 8 is provided below the lifting platform 5, which can drive the lifting platform 5 to move up and down. A pressing platform 9 is provided at the upper end of the holding platform 1, with multiple air inlets 10. The air inlets 10 correspond one-to-one with the round holes 2 and are located above the round holes 2. A transmission frame 11 is installed on the holding platform 1. When the lifting platform 5 moves up and down, it can drive the pressing platform 9 to move up and down through the transmission frame 11. When the lifting platform 5 moves downward, it can push the supporting steel cage 4 downward.

[0020] The dust removal process of this device for the dust collector bag 3 is as follows: Under normal conditions, the dust collector bag 3 removes dust from the exhaust gas, and the dust adheres to the outside of the dust collector bag 3. The air after dust removal can enter the inside of the dust collector bag 3 and then be discharged from the top. The supporting steel cage 4 can support the dust collector bag 3 and prevent the dust collector bag 3 from shrinking due to negative pressure. When it is necessary to remove dust from the outside of the dust collector bag 3, the drive frame 8 drives the lifting platform 5 to move downwards, which in turn causes the lifting platform 5 to drive the cleaning brush 7 to move downwards and clean the outside of the dust collector bag 3. When the lifting platform 5 moves to the bottom, the transmission frame 11 drives the pressing platform 9 to move downwards, and the pressing platform 9 can... Pushing the supporting steel cage 4 downwards supports the lower end of the dust collector bag 3. When the drive frame 8 moves the lifting platform 5 and cleaning brush 7 upwards, the dust collector bag 3 is cleaned again. Supporting the lower end of the dust collector bag 3 prevents wrinkles. After dust removal, the pressing platform 9 is moved upwards via the transmission frame 11 to prevent the supporting steel cage 4 from continuously pressing the dust collector bag 3, thus extending its service life. After cleaning, high-pressure air is used for backflushing, allowing air to enter the dust collector bag 3 through the air inlet 10 for dust removal, facilitating the removal of impurities.

[0021] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The drive frame 8 includes four screw jacks 12 located below the holding platform 1. The four screw jacks 12 are driven to rotate by a power component. The output end of the screw jack 12 is equipped with a transmission screw 13. Threaded holes 14 are opened at the four corners of the lifting platform 5. The transmission screw 13 and the threaded holes 14 are connected by threads. Multiple clearance openings 15 are opened on the holding platform 1. The clearance openings 15 correspond one-to-one with the threaded holes 14 and are located above the threaded holes 14. A protective box 16 is installed on the upper end of the clearance opening 15. A rolling bearing 17 is installed on the upper end of the transmission screw 13. The upper end of the rolling bearing 17 is installed on the upper surface inside the protective box 16.

[0022] The process of the drive frame 8 driving the lifting platform 5 to move up and down is as follows: the power unit can drive the four screw jacks 12 to rotate synchronously, and the screw jacks 12 drive the transmission screws 13 to rotate. Through the threaded connection between the transmission screws 13 and the threaded hole 14, the lifting platform 5 can be driven to move up and down. The upper end of the transmission screws 13 can pass through the clearance opening 15 and extend into the protective box 16, which makes it easier for the lifting platform 5 to move upward a greater distance. The protective box 16 can also prevent dust below the container platform 1 from passing through the clearance opening 15 and moving to the top of the container platform 1.

[0023] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The lifting platform 5 has multiple limiting holes 18, and a limiting rod 19 is provided in the limiting hole 18. The upper end of the limiting rod 19 is fixedly connected to the lower surface of the serving platform 1. The moving direction of the lifting platform 5 can be ensured by the limiting rod 19 and the limiting hole 18, and the force between the transmission screw 13 and the threaded hole 14 can be reduced.

[0024] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 A first telescopic dust cover 20 is installed at the upper end of the threaded hole 14. The upper end of the first telescopic dust cover 20 extends through the clearance opening 15 into the protective box 16 and is connected to the inner surface of the protective box 16. A second telescopic dust cover 21 is installed at the lower end of the threaded hole 14. The lower end of the second telescopic dust cover 21 is connected to the upper end of the screw jack 12. The first telescopic dust cover 20 and the second telescopic dust cover 21 can cover the transmission screw 13, thereby protecting the transmission screw 13 and preventing dust from adhering to the transmission screw 13.

[0025] The first telescopic dust cover 20 and the second telescopic dust cover 21 are both circular accordion-style dust covers, which allow the dust covers to have a large telescopic ratio and reduce the space occupied by the dust covers.

[0026] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4The transmission frame 11 includes a circular lifting plate 22 installed above the inner side of the first telescopic dust cover 20. A pressing rod 23 is installed on the upper end of the circular lifting plate 22. An inlet and outlet 24 is opened on the upper end of the protective box 16. Multiple limiting platforms 25 are installed on both sides of the pressing platform 9. One end of the pressing rod 23 passes through the inlet and outlet 24 and extends above the limiting platform 25. A positioning hole 26 is opened on one side of the limiting platform 25. A first spring rod 27 is installed on the protective box 16 on one side of the positioning hole 26. A pulley 28 is installed on the telescopic end of the first spring rod 27. One end of the pulley 28 abuts against the side surface of the limiting platform 25. The pressing platform 9 is connected to the holding platform 1 through multiple second spring rods 29, providing support. A support plate 30 is installed on the outside of the steel cage 4. Multiple third spring rods 31 are installed at the lower end of the support plate 30, and multiple elastic pads 32 are installed at the upper end of the support plate 30. When the pressing table 9 moves downward, the support plate 30 can push the supporting steel cage 4 downward. Multiple push rods 33 are installed on the outside of the threaded hole 14 and mounted on the lifting platform 5. The upper end of the push rod 33 can contact the lower end of the circular lifting plate 22. Multiple guide holes 34 are opened on the circular lifting plate 22. Guide rods 35 are installed in the guide holes 34. The upper end of the guide rods 35 contacts the inner surface of the protective box 16. A reset frame 36 is installed on the pressing rod 23. The reset frame 36 resets the first spring rod 27.

[0027] The process of the transmission frame 11 driving the pressing platform 9 to move up and down is as follows: Under normal conditions, the second spring rod 29 supports the pressing platform 9. The pressing platform 9 can support the circular lifting plate 22 through the limiting platform 25 and the pressing rod 23. The third spring rod 31 supports the supporting steel cage 4. When the lifting platform 5 moves downward, it can drive the first telescopic dust cover 20 to move downward. When the lower end of the first telescopic dust cover 20 is straightened, the circular lifting plate 22 can be pulled downward. Then, the pressing platform 9 can be pushed downward through the circular lifting plate 22, the pressing rod 23, and the limiting platform 25, and the second spring rod 29 can be compressed. When the pressing platform 9 moves downward, the positioning hole 26 can be moved to the side of the pulley 28. Then, under the elastic force of the first spring rod 27, the pulley 28 can be pushed into the positioning hole 26, thereby positioning the pressing platform 9. When the support plate 30 and the support steel cage 4 are pushed downwards, the third spring rod 31 is compressed, and the lower end of the dust collector bag 3 is supported by the support steel cage 4. Then, when the lifting platform 5 moves the cleaning brush 7 upwards, the dust collector bag 3 is prevented from wrinkling. The elastic pad 32 allows for the error of squeezing the support steel cage 4 when the pressing platform 9 moves downwards, preventing damage to the dust collector bag 3. Then, the dust collector bag 3 can be cleaned by repeatedly moving the lifting platform 5 up and down. After the dust is cleaned, the lifting platform 5 is moved to the top and the push rod 33 is moved upwards. The push rod 33 can move the annular lifting plate 22 and the pressing rod 23 upwards. Then, the first spring rod 27 is reset by the reset frame 36. Then, under the elastic force of the second spring rod 29 and the third spring rod 31, the pressing platform 9 and the support steel cage 4 are reset respectively.

[0028] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 4 The reset frame 36 includes a reset plate 37 installed at the lower end of the pressing rod 23. A first rotating roller 38 is installed at the lower end of the reset plate 37. A rotating plate 39 is installed on the first rotating roller 38. A fixing rod 40 is installed on the reset plate 37 on one side above the first rotating roller 38. A fixing plate 41 is installed on the other side above the first rotating roller 38. The fixing plate 41 and the rotating plate 39 are connected by a telescopic spring 42. The telescopic spring 42 can push the rotating plate 39 onto the fixing rod 40. A second rotating roller 43 is installed on one side of the first spring rod 27 below the rotating plate 39.

[0029] The process of the reset frame 36 resetting the first spring rod 27 is as follows: Under normal conditions, the first spring rod 27 is in a compressed state, and one end of the pulley 28 is pressed against the limiting platform 25. When the pressing rod 23 moves downward, the reset plate 37, the first rotating roller 38, the rotating plate 39, the fixing rod 40, the fixing plate 41, and the telescopic spring 42 can move downward. At this time, the second rotating roller 43 is located below the rotating plate 39. Therefore, when the rotating plate 39 moves downward, the second rotating rod 43 can lift the rotating plate 39 and make the rotating plate 39 rotate around the first rotating roller 38. This can compress the telescopic spring 42, allowing the rotating plate 39 to avoid the second rotating roller 43, making it easier for the rotating plate 39 to move below the second rotating roller 43. When the rotating plate 39 moves to the second rotating roller 43, the second rotating rod 48 will move downward. After the bottom is lowered, the rotating plate 39 can return to its original position under the elastic force of the telescopic spring 42 and be intercepted by the fixed plate 41. After the positioning hole 26 moves to the side of the pulley 28, one end of the pulley 28 can enter the positioning hole 26. When the annular lifting plate 22 moves upward and drives the pressing rod 23 to reset plate 37, first rotating roller 38, rotating plate 39, fixed rod 40, fixed plate 41, and telescopic spring 42 to move upward, since one end of the rotating plate 39 is intercepted by the fixed rod 40, when the rotating plate 39 moves upward and contacts the second rotating roller 43, the second rotating roller 43 can move along the inclined surface of the rotating plate 39 and cause the first spring rod 27 to retract, thereby allowing the pulley 28 to move to the outside of the positioning hole 26, which facilitates the reset of the limiting platform 25.

[0030] Refer to the instruction manual appendix Figure 6 The power components include a dual-shaft output motor 44. The two output ends of the dual-shaft output motor 44 are connected to a reducer 46 via a transmission shaft 45. The reducer 46 has two output ends, which are respectively connected to the input ends of two screw jacks 12 via transmission rods 47. The dual-shaft output motor 44 drives the reducer 46 to rotate, which in turn drives the screw jacks 12 to rotate, thereby enabling the four screw jacks 12 to rotate synchronously.

[0031] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 6 Dustproof boxes 48 are installed on the outside of the dual-shaft output motor 44, reducer 46, and screw jack 12. Rotary sealing treatment is provided at the intersection of the input and output ends of the dustproof box 48 and the dual-shaft output motor 44, reducer 46, and screw jack 12. The dustproof box 48 is installed on the upper end of the hopper of the bag dust collector. The dustproof box 48 can prevent the dust under the holding platform 1 from contacting the dual-shaft output motor 44, reducer 46, and screw jack 12, thereby extending the service life of the dual-shaft output motor 44, reducer 46, and screw jack 12.

[0032] A bag filter dust collector has a holding platform 1 installed on the upper side of the filter box of the bag filter dust collector. The holding platform 1 isolates the filter box into upper and lower ends, thereby preventing dust leakage.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
