Description

Technical Field

[0001] This invention relates to the field of dust collector inner wall cleaning technology, and particularly to a rotary cleaning assembly and method for the inner wall of a pulse bag dust collector. Background Technology

[0002] Pulse jet baghouse dust collectors are mainly used to purify dust-laden gases emitted from industrial facilities. There are already relevant patents for dust collection equipment, such as CN201920760352.5, which discloses a lifting-type dust removal and cleaning device for a dust collector. This dust collector, by adding a cleaning frame inside, can clean the inner wall of the dust collector. A cylinder drives a guide frame to move up and down reciprocatingly, causing the brushes on the outside of the guide frame to clean the inner wall of the dust collector, preventing dust accumulation and reducing the dust collector's efficiency. Furthermore, the device is installed inside the dust collector, allowing for direct cleaning without manual intervention.

[0003] The patent has the following problems that need to be solved in the actual dust removal process:

[0004] 1. If the guide frame is raised and lowered by a cylinder, then for some taller dust collectors, the height of the cylinder also needs to be similar to the height of the dust collector, which results in a larger size of the cleaning equipment.

[0005] 2. The length of the guide frame is set to remain unchanged. Since the dust collector adopts a rectangular structure, its width and length are different. Therefore, when cleaning the long side, the guide frame needs to be moved horizontally to achieve the purpose of cleaning. Summary of the Invention

[0006] The purpose of this invention is to provide a rotary cleaning assembly and method for the inner wall of a pulse bag filter to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rotary cleaning assembly for the inner wall of a pulse bag dust collector, comprising a cleaning frame and a storage plate installed on the cleaning frame, wherein the storage plate is provided with a power assembly for driving the extension and retraction of the moving assembly;

[0008] Driven by the power component, the moving component extends and connects with the inner walls of the two symmetrical sides of the dust collector. The moving component is used to drive the entire device to move up and down along the dust collector.

[0009] The side of the moving component is connected to a cleaning tube via a connecting rod. The power component is also connected to the inner cavity of the cleaning tube. Telescopic components extending into the inner cavity are inserted at both ends of the cleaning tube.

[0010] The cleaning pipe is equipped with a cleaning component with a moving function, wherein the moving function is provided by a transmission device on the cleaning component.

[0011] Furthermore, the cleaning frame includes a lower frame, an upper frame, and connecting rods. Both the lower frame and the upper frame are "H" shaped and are fixed together by several connecting rods. The shelf is welded to the upper frame.

[0012] Furthermore, the moving assembly includes a telescopic rod, a left support plate, a right support plate, a moving wheel, and a drive belt;

[0013] The lower and upper frames are tubular components with one end open and the other end closed. The left support plate is fixed to the closed end of the lower and upper frames. Two sets of wheel support assemblies are connected to the left and right support plates respectively, and the moving wheels are set on the wheel support assemblies.

[0014] One end of the telescopic rod is inserted into the openings of the lower and upper frames, and the other end of the telescopic rod is connected to the right support plate. The telescopic rod extends to the moving wheels on both sides and connects to the inner walls of the dust collector on both sides, which is used to drive the entire equipment to rise and fall.

[0015] Furthermore, each wheel support assembly includes a wheel frame and a drive shaft, with both ends of the drive shaft inserted into bearings on both sides of the wheel frame;

[0016] A power motor and a reducer are also connected to the left support plate. The power motor and the reducer are both located on the left support plate. The power motor is connected to the drive shaft on the left support plate via a drive belt. The power motor outputs power to the reducer. The power output by the reducer after deceleration is driven by the connected drive belt to drive the rotating wheels and drive the entire equipment to lift.

[0017] Furthermore, the power assembly includes an air pump, an air source box, and air pipes. The air pump and air source box are mounted on the shelf. One end of the air pump is connected to the air source box, and the other end of the air pump is connected to the inner cavity of the upper frame and the cleaning pipe through two air pipes. This is used to drive the telescopic rod and telescopic components to extend or shorten, adapting to dust collectors of different sizes.

[0018] Furthermore, the telescopic component includes a telescopic support rod, a limiting main groove, and a limiting secondary groove. The telescopic support rod has a limiting secondary groove along its length, and the cleaning pipe has a limiting main groove along its length. The telescopic support rod is inserted into the opening of the cleaning pipe, and a sealing block for sealing the limiting secondary groove is provided in the opening of the cleaning pipe. The telescopic support rod and the cleaning pipe are sealed together.

[0019] Furthermore, the cleaning assembly includes a wheel body, a cleaning rod, a brush plate, a cleaning brush, a wheel frame, a spring, and a limiting arc plate, with the wheel body inserted into the limiting main groove;

[0020] The limiting arc plate connected to the bottom of the wheel frame contacts the bottom of the cleaning pipe. A horizontal plate is fixed to the top of the wheel frame, and a cleaning motor is placed on the horizontal plate. The shaft of the cleaning motor is connected to one end of the cleaning rod, and the other end of the cleaning rod is connected to the cleaning brush. The cleaning brush is embedded in the through hole of the brush plate.

[0021] A guide rod is fitted on the axle of the wheel body. The top end of the guide rod passes through a horizontal plate. A spring is fitted on the guide rod. One end of the spring is connected to the wheel frame, and the other end of the spring is connected to the protruding plate on the guide rod.

[0022] Furthermore, the transmission device includes an upper transmission shaft, a bevel gear, and a lower transmission shaft. The upper transmission shaft passes through the bearing of the horizontal plate, and one end of the upper transmission shaft meshes with the shaft of the cleaning motor through the bevel gear.

[0023] The other end of the upper drive shaft is provided with a through hole and a protrusion on the inner wall of the through hole. One end of the lower drive shaft is provided with a groove. The lower drive shaft is inserted into the upper drive shaft, and the protrusion and the groove engage with each other. The other end of the lower drive shaft passes through the bearing of the protrusion plate and meshes with the shaft of the wheel body through a bevel gear.

[0024] This invention provides another technical solution, including a method for using a rotary cleaning assembly for the inner wall of a pulse jet bag filter, comprising the following steps:

[0025] S1: The cleaning frame is placed on one side of the inner wall of the dust collector. The cleaning brush contacts the inner wall of the air box pulse bag dust collector. The air pump introduces gas into the upper frame and the cleaning pipe. The telescopic rod and telescopic support rod extend until the moving wheels on both sides of the telescopic rod contact the two inner walls of the dust collector. The pulleys at the ends of the telescopic support rod also contact the two inner walls of the dust collector.

[0026] S2: The cleaning motor starts, driving the cleaning rod and the upper drive shaft to rotate. During the rotation of the cleaning rod, the brush plate and the cleaning brush rotate synchronously. The cleaning brush rotates to clean the inner wall of the dust collector, while the rotation of the upper drive shaft drives the lower drive shaft and the wheel to rotate.

[0027] S3: The wheel moves along the telescopic support rod, and when the wheel moves into the limiting secondary groove, the spring rebounds to keep the wheel moving in the limiting main groove and the limiting secondary groove. Through the movement of the wheel, the cleaning brush cleans the dust collector horizontally. After the horizontal cleaning is completed;

[0028] S4: The moving wheels move down, and the cleaning brush rotates while sweeping horizontally along the inner wall of the dust collector.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. The movable wheels of the present invention can press against the two symmetrical inner walls of the dust collector under pressure. The rotation of the movable wheels can drive the device to move up and down along the dust collector. Furthermore, the movable wheels of the device can be extended and retracted by telescoping, so that the device only needs a small volume, which facilitates the transportation of the device and solves the problem of excessive size.

[0031] 2. This invention uses an air pump to fill or extract gas into the upper frame and cleaning pipe, thereby extending or shortening the telescopic rod and telescopic support rod, thus increasing the moving distance of the cleaning component. Since the telescopic rod and telescopic support rod are telescopic, the wheel body, under the action of the spring, can always be located within the limiting main groove and limiting secondary groove. Furthermore, the cleaning motor provides power to the wheel body and cleaning brush, thereby saving power costs and enabling a thorough and clean cleaning of the inner wall of the dust collector.

[0040] 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, and 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.

[0041] To address the issue that existing cylinder-driven guide frame lifting systems require the cylinder height to be similar to the dust collector's height for some taller dust collectors, resulting in a larger cleaning device size, the following technical solution is provided. Please refer to [link / reference]. Figure 1 ;

[0042] A rotary cleaning assembly for the inner wall of a pulse bag filter includes a cleaning frame 1 and a storage plate 2 mounted on the cleaning frame 1. The storage plate 2 is provided with a power assembly 4 for driving the extension and retraction of the moving assembly 3.

[0043] Driven by the power component 4, the moving component 3 extends and connects with the inner walls of the two symmetrical sides of the dust collector. The moving component 3 is used to drive the entire device to move up and down along the dust collector.

[0044] The side of the moving component 3 is connected to the cleaning pipe 22 via the connecting rod 21. The power component 4 is also connected to the inner cavity of the cleaning pipe 22. Telescopic components 5 extending into the inner cavity are inserted at both ends of the cleaning pipe 22.

[0045] The cleaning pipe 22 is equipped with a cleaning component 6 with a moving function, wherein the moving function is provided by a transmission device 7 on the cleaning component 6.

[0046] The cleaning rack 1 includes a lower frame 11, an upper frame 12 and connecting rods 13. Both the lower frame 11 and the upper frame 12 are "H" shaped. The lower frame 11 and the upper frame 12 are fixed together by several connecting rods 13, and the shelf 2 is welded to the upper frame 12.

[0047] The movable component 3 includes a telescopic rod 31, a left support plate 32, a right support plate 33, a movable wheel 34, and a transmission belt 35;

[0048] The lower frame 11 and the upper frame 12 are tubular components with one end open and the other end closed. The left support plate 32 is fixed on the closed end of the lower frame 11 and the upper frame 12. Two sets of wheel support assemblies 8 are connected to the left support plate 32 and the right support plate 33 respectively. The moving wheel 34 is set on the wheel support assembly 8.

[0049] One end of the telescopic rod 31 is inserted into the openings of the lower frame 11 and the upper frame 12, and the other end of the telescopic rod 31 is connected to the right support plate 33. The telescopic rod 31 extends to the moving wheels 34 on both sides and connects to the inner walls of both sides of the dust collector. The rotation of the moving wheels 34 is used to drive the entire equipment to lift and lower.

[0050] Each wheel support assembly 8 includes a wheel frame 81 and a power transmission shaft 82, with both ends of the power transmission shaft 82 inserted into bearings on both sides of the wheel frame 81.

[0051] A power motor 36 and a reducer 37 are also connected to the left support plate 32. Both the power motor 36 and the reducer 37 are mounted on the left support plate 32. The power motor 36 is connected to the power transmission shaft 82 on the left support plate 32 via a transmission belt 35. The power motor 36 outputs power to the reducer 37. The power output by the reducer 37 after deceleration is transmitted through the connected transmission belt 35 to drive the moving wheel 34 to rotate and drive the entire equipment to lift.

[0052] Specifically, the drive belt 35 is rotated by the power motor 36, and the moving wheel 34 can press against the two symmetrical inner walls of the dust collector under pressure. The rotation of the moving wheel 34 can drive the equipment to move up and down along the dust collector. Furthermore, the moving wheel 34 can be extended and retracted by telescopic extension, so that the equipment only needs a small size, which facilitates the transportation of the equipment and solves the problem of excessive size.

[0053] To address the issue that existing guide frames have a fixed length, while dust collectors with rectangular structures have varying widths and lengths, requiring horizontal movement of the guide frame to achieve thorough cleaning of the longer side, the following technical solution is provided. Please refer to [link / reference]. Figure 1-7 ;

[0054] The power assembly 4 includes an air pump 41, an air source box 42, and an air pipe 43. The air pump 41 and the air source box 42 are mounted on the shelf 2. One end of the air pump 41 is connected to the air source box 42, and the other end of the air pump 41 is connected to the inner cavity of the upper frame 12 and the cleaning pipe 22 through the air pipe 43. It is used to drive the telescopic rod 31 and the telescopic component 5 to extend or shorten, so as to adapt to dust collectors of different sizes.

[0055] The telescopic component 5 includes a telescopic support rod 51, a limiting main groove 52, and a limiting secondary groove 53. The telescopic support rod 51 has a limiting secondary groove 53 along its length, and the cleaning pipe 22 has a limiting main groove 52 along its length. One end of the telescopic support rod 51 is inserted into the opening of the cleaning pipe 22, and the other end of the telescopic support rod 51 is connected to the right support plate 33 to improve support. A sealing block for sealing the limiting secondary groove 53 is provided in the opening of the cleaning pipe 22, and the telescopic support rod 51 and the cleaning pipe 22 are sealed together.

[0056] The cleaning assembly 6 includes a wheel body 61, a cleaning rod 62, a brush plate 63, a cleaning brush 64, a wheel frame 65, a spring 66, and a limiting arc plate 67. The wheel body 61 is inserted into the limiting main groove 52.

[0057] The limiting arc plate 67 connected to the bottom of the wheel frame 65 contacts the bottom of the cleaning pipe 22. A horizontal plate 651 is fixed to the top of the wheel frame 65. A cleaning motor is placed on the horizontal plate 651. The shaft of the cleaning motor is connected to one end of the cleaning rod 62. The other end of the cleaning rod 62 is connected to the cleaning brush 64. The cleaning brush 64 is embedded in the through hole of the brush round plate 63.

[0058] A guide rod is fitted on the axle of the wheel body 61. The top end of the guide rod passes through the cross plate 651. A spring 66 is fitted on the guide rod. One end of the spring 66 is connected to the wheel frame 65, and the other end of the spring 66 is connected to the protrusion on the guide rod.

[0059] The transmission device 7 includes an upper transmission shaft 71, a bevel gear 72 and a lower transmission shaft 73. The upper transmission shaft 71 passes through the bearing of the horizontal plate 651, and one end of the upper transmission shaft 71 meshes with the shaft of the cleaning motor through the bevel gear 72.

[0060] The other end of the upper drive shaft 71 is provided with a through hole and a protrusion is provided on the inner wall of the through hole. One end of the lower drive shaft 73 is provided with a groove. The lower drive shaft 73 is inserted into the upper drive shaft 71, and the protrusion and the groove are engaged with each other. The other end of the lower drive shaft 73 passes through the bearing of the protrusion plate and meshes with the shaft of the wheel body 61 through the bevel gear 72.

[0061] Specifically, by pumping or extracting gas into the upper frame 12 and the cleaning pipe 22 using the air pump 41, the telescopic rod 31 and the telescopic support rod 51 are extended or shortened, thus increasing the moving distance of the cleaning component 6. This ensures that the moving distance of the cleaning component 6 is the same as the length of the dust collector to be cleaned. The limiting arc plate 67 prevents the wheel frame 65 from detaching from the telescopic rod 31 and the telescopic support rod 51. Since the telescopic rod 31 and the telescopic support rod 51 are telescopic, the wheel 61, under the action of the limiting main groove 52 and the limiting secondary groove 53, can always remain within the limiting main groove 52 and the limiting secondary groove 53 under the action of the spring 66. Furthermore, the cleaning motor provides power to the wheel 61 and the cleaning brush 64, thereby saving power costs and enabling a thorough and clean cleaning of the inner wall of the dust collector.

[0062] To better demonstrate the usage process of the rotary cleaning assembly on the inner wall of a pulse jet bag filter, this embodiment provides a method for using the rotary cleaning assembly, including the following steps:

[0063] Step 1: The cleaning frame 1 is placed on one inner wall of the dust collector. The cleaning brush 64 contacts the inner wall of the air box pulse bag dust collector. The air pump 41 introduces gas into the upper frame 12 and the cleaning pipe 22. The telescopic rod 31 and the telescopic support rod 51 extend until the moving wheels 34 on both sides of the telescopic rod 31 contact the two inner walls of the dust collector. The pulleys at the ends of the telescopic support rod 51 also contact the two inner walls of the dust collector.

[0064] Step 2: The cleaning motor starts, driving the cleaning rod 62 and the upper drive shaft 71 to rotate. During the rotation of the cleaning rod 62, the brush plate 63 and the cleaning brush 64 rotate synchronously. The cleaning brush 64 rotates to clean the inner wall of the dust collector, while the rotation of the upper drive shaft 71 drives the lower drive shaft 73 and the wheel 61 to rotate.

[0065] Step 3: The wheel 61 moves along the telescopic support rod 51, and when the wheel 61 moves into the limiting secondary groove 53, the spring 66 rebounds to keep the wheel 61 moving within the limiting main groove 52 and the limiting secondary groove 53. Through the movement of the wheel 61, the cleaning brush 64 cleans the dust collector horizontally. After the horizontal cleaning is completed;

[0066] Step 4: Move the moving wheel 34 down and clean the brush 64 while rotating to sweep horizontally along the inner wall of the dust collector.

[0067] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
