Description

Technical Field

[0001] This invention relates to the field of environmentally friendly pulse back-blowing vacuum cleaner technology, and in particular to an environmentally friendly pulse back-blowing vacuum cleaner for grinding the edges of paper core plugs. Background Technology

[0002] When processing paper core plugs, the paper core plugs need to be sanded to make them suitable for use. During the sanding process, a lot of dust will be generated. The conventional solution is to use a vacuum cleaner to remove the dust to improve the environmental protection effect.

[0003] An environmentally friendly pulse jet vacuum cleaner, with announcement number CN119926062B, includes a base plate, a second housing, and filter cartridges. A pulse jet assembly is installed in the first housing, a self-positioning mounting assembly is installed in the second housing, and a high-efficiency dust removal assembly is installed in the second housing. In the engaged and fixed state of the first and second housings, the invention utilizes a hydraulic rod and the high-efficiency dust removal assembly to conveniently transfer and process collected dust and impurities, completing the dust removal process. In the separated state of the first and second housings, the self-positioning mounting assembly allows for batch disassembly, assembly, and replacement of filter cartridges, improving the practicality and convenience of the pulse jet vacuum cleaner.

[0004] The above technical solution can collect and transfer dust and impurities, but it cannot guarantee the backflushing effect and cannot fully remove the dust and impurities attached to the filter cartridge, which is not conducive to extending the service life of the equipment. Therefore, it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose an environmentally friendly pulse back-blowing vacuum cleaner for grinding the edges of paper core plugs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An environmentally friendly pulse back-blowing vacuum cleaner for grinding paper core plugs includes a dust removal equipment assembly. An air extraction chamber is fixed on one side of the dust removal equipment assembly. A sealing partition is fixed between the dust removal equipment assembly and the air extraction chamber. A negative pressure power mechanism is installed at the lower end of the air extraction chamber. A power connector is provided on the negative pressure power mechanism. A directional extraction mechanism is installed at one end of the power connector. The directional extraction mechanism is installed at the lower end of the dust removal equipment assembly.

[0008] The dust removal equipment component is provided with a diagonal support frame on the side away from the extraction chamber. Multiple filter tubes are installed at equal intervals on the diagonal support frame. One end of each filter tube passes through a closed partition and extends into the extraction chamber. A high-pressure air conveying mechanism is installed on both the extraction chamber and the dust removal equipment component. Multiple air supply pipes are provided on the high-pressure air conveying mechanism. All multiple air supply pipes pass through the extraction chamber and extend into the multiple filter tubes respectively.

[0009] A first disc is fixed to one end of the air supply pipe. An aeration mechanism is installed on the first disc. An impact mechanism is installed inside the air supply pipe. A fixed shaft is provided on the impact mechanism. A second disc is fixed to one end of the fixed shaft. Multiple sealing arc plates are fixed on the second disc. Multiple arc plates are fixed on the first disc. The aeration mechanism is connected to the arc plates.

[0010] Compared with the prior art, this application can use high-pressure gas as a power source to realize the rotation of the sealing arc plate, so that the arc plate and the sealing arc plate form a closed cylinder, reducing the space occupied by the gas in the filter tube, controlling the change of gas flow direction, so as to fully backflush and purify the filter tube, and utilizing inertia to avoid the gas directly impacting the filter tube, which helps to extend the service life of the filter tube.

[0011] Preferably, a suction pipe is installed on one side of the upper end of the dust removal equipment component, and one end of the suction pipe is connected to an edge grinding device.

[0012] Furthermore, the edge grinding equipment can perform edge grinding operations on paper core plugs. This operation is a common technical means in the field and does not need to be explained again. During edge grinding, a large amount of dust will be generated inside the edge grinding equipment. Through the action of the suction pipe, the air and dust inside the edge grinding equipment can be brought into the dust removal equipment component so that the dust removal equipment component can purify the gas, collect the dust, and discharge the purified gas.

[0013] Preferably, the negative pressure power mechanism includes a discharge pipe fixed at the lower end of the suction chamber, a motor assembly installed on one side of the discharge pipe, a suction assembly fixed at the end of the output shaft of the motor assembly, the suction assembly being disposed through the suction chamber and the discharge pipe, one end of the power connector being rotatably sleeved on the side of the lower end of the suction chamber away from the discharge pipe, and the other end of the power connector being through the suction chamber and connected to the suction assembly.

[0014] Furthermore, the motor assembly can drive the air extraction assembly to rotate. The air extraction assembly is equipped with a fan blade mechanism. Through the joint rotation of the air extraction assembly and the motor assembly, the fan blades drive the gas to flow from the air extraction chamber towards the discharge pipe. This causes the gas outside the back-blowing to flow along the edge grinding equipment into the suction pipe, dust removal equipment assembly, filter pipe and air extraction chamber, and finally out through the discharge pipe.

[0015] During the above process, the dust-laden gas inside the edge grinding equipment can be thoroughly purified through the filter tube;

[0016] Meanwhile, the extraction assembly and power connection are set by the staff according to the actual situation, that is, the extraction assembly and power connection can rotate relative to the discharge pipe and the extraction chamber, and the motor assembly can drive the extraction assembly to rotate.

[0017] Preferably, the directional extraction mechanism includes a discharge pipe that runs through the lower end of the dust removal equipment component, an auger output component is installed at the lower end of the discharge pipe, an electrically controlled valve is installed on one side of the lower end of the auger output component, and the auger output component is connected to a power connection component.

[0018] Furthermore, when the power connector drives the auger output component to rotate, it enables the auger component inside the auger output component to rotate. By controlling the rotation direction of the auger component and the setting position of the electric control valve, impurities can be discharged through the electric control valve.

[0019] In actual operation, the electrically controlled valve can be connected to the supporting equipment to ensure the centralized collection of impurities and prevent impurities from scattering.

[0020] Preferably, the high-pressure gas transmission mechanism includes a high-pressure gas supply component installed on the upper end of the dust removal equipment component. One end of the high-pressure gas supply component is connected to a high-pressure gas storage tank. The high-pressure gas storage tank is fixed to one side of the extraction chamber. Both ends of the high-pressure gas storage tank are provided with multiple edge grinding devices. Multiple gas supply pipes are respectively installed through the multiple edge grinding devices. An electric control valve is installed on the gas supply pipe.

[0021] A pressure detection component is installed on one side of the lower end of the high-pressure gas storage tank.

[0022] Furthermore, the high-pressure gas supply component can extract gas and deliver it to the high-pressure gas storage tank, creating a high-pressure state inside the high-pressure gas storage tank. At the same time, the high-pressure gas storage tank and its connected components all use high-pressure components to ensure installation safety.

[0023] The air pressure detection component can detect the gas pressure value in the high-pressure air storage tank and the grinding equipment, and can upload the gas pressure value so that the control component on the dust removal equipment can receive and process it. When the pressure reaches the set pressure value, it can control the electric control valve to realize the gas flow so as to perform pulse backflushing.

[0024] In actual operation, the control equipment on the dust removal equipment component can output corresponding programs according to the actual situation, and the dust removal equipment component is equipped with matching components, such as power connection and equipment control components. The existing technology is used for assembly to ensure that each automated component can work according to the program settings and program control. This is a common technical means in this field.

[0025] The pressure inside the high-pressure gas storage tank and the grinding equipment is the same. The high-pressure gas supply component fills the tank with gas, causing the gas pressure inside the tank and the grinding equipment to rise. The gas pressure detection component monitors the gas pressure. When the set gas pressure is reached, the electronic control valve can be controlled to allow the high-pressure gas to enter the pulse gas delivery pipe through the gas supply pipe for backflushing.

[0026] Preferably, the aeration mechanism includes multiple pulse air delivery pipes that are equally spaced and pass through the air supply pipe, the multiple pulse air delivery pipes are respectively fixed on multiple arc-shaped plates, and the multiple pulse air delivery pipes are all fixedly connected to the first disc;

[0027] The first disk has multiple openings at equal intervals, and the multiple openings and multiple pulse gas delivery pipes are arranged alternately.

[0028] Furthermore, the pulse gas delivery pipe is a bent hollow structure. The vertical end of the pulse gas delivery pipe is fixedly connected to and passes through the gas supply pipe, so that gas can enter the pulse gas delivery pipe through the gas supply pipe. At the same time, the horizontal end of the pulse gas delivery pipe is arc-shaped so that it can be fixed to the arc plate. Openings or holes are opened on both sides of the horizontal end of the pulse gas delivery pipe. The curvature of the openings or holes is the same as the curvature of the arc plate. Through this design, the high-pressure gas can move inertially along the arc of the openings or holes, so as to reduce the direct impact on the filter tube.

[0029] The opening facilitates gas flow, allowing the gas, after being cleaned by the filter tube, to quickly pass through the sealed partition and enter the extraction chamber.

[0030] Preferably, the impact mechanism includes a fixed frame fixed inside the air supply pipe, one end of the fixed frame is rotatably sleeved with a linkage shaft with turbine blades, and one end of the linkage shaft with turbine blades is fixedly connected to the fixed shaft.

[0031] A reset mechanism is provided between the linkage shaft with turbine blades and the air supply pipe.

[0032] Furthermore, the linkage shaft with turbine blades is installed inside the air supply pipe, and the stability of the installation of the linkage shaft with turbine blades can be ensured by the fixing bracket, thereby ensuring the stability of the fixing shaft. At the same time, in actual operation, the structure of vortex blades on the linkage shaft with turbine blades can be set to ensure that the high-pressure gas entering the air supply pipe can impact the blades, so that the linkage shaft with turbine blades can rotate in a specific direction. The setting scheme is common knowledge in the field and does not need to be disclosed again.

[0033] By using a linkage shaft with turbine blades and high-pressure gas, the backflushing cleaning effect is enhanced during pulse backflushing, and the stable flow of purified gas is ensured by the reset mechanism after backflushing cleaning is completed.

[0034] Preferably, the reset mechanism includes a linkage plate fixed on a linkage shaft with turbine blades. The linkage plate and the inner wall of the air supply pipe are both fixed with a tension spring. When the vortex blades on the linkage shaft with turbine blades rotate under the impact of high-pressure gas, the linkage plate can drive the tension spring to move, causing the tension spring to be stretched. When the high-pressure gas stops impacting, the tension spring can pull the linkage plate and the linkage shaft with turbine blades to reset, so that the linkage shaft with turbine blades can drive the sealing arc plate to reset through the fixed shaft and the second disc. This allows the space inside the filter tube to be unobstructed, facilitating rapid gas flow, so that the purified gas can pass through the filter tube and enter the side of the closed partition away from the suction pipe.

[0035] Preferably, the outer sides of the multiple sealing arc plates abut against the inner sides of the multiple arc plates respectively, the sealing arc plates and the arc plates have the same angle, the inner walls of the multiple arc plates and the outer walls of the multiple sealing arc plates together form a circle, and the center of the circle formed by the inner walls of the multiple arc plates and the outer walls of the multiple sealing arc plates overlaps with the axis of the fixed shaft.

[0036] Furthermore, the sum of the angles of the multiple sealing arc plates is 360° or greater. In this way, it can be ensured that when the multiple sealing arc plates rotate, they can form a circular tube structure, and the sealing of the circular tube is guaranteed, reducing gas leakage. For example, in actual operation, a sealing gasket can be set on one side of the sealing arc plate in the direction of rotation. When the sealing arc plate rotates under the impact of high-pressure gas, the sealing gasket and the arc plate can come into contact to seal.

[0037] The sealing mechanism described above reduces the space occupied by the gas output from the pulse gas delivery pipe;

[0038] Furthermore, in actual operation, the friction between the sealing arc plate and the arc plate is reduced according to existing technology, so as to ensure that the sealing arc plate can rotate under the action of the fixed shaft and the second disc. That is, when the high-pressure gas impacts the linkage shaft with the turbine fan blade, the linkage shaft with the turbine fan blade can pull the tension spring, and at the same time drive the fixed shaft and the second disc to rotate, so that multiple sealing arc plates and multiple arc plates form a circular tube structure.

[0039] Preferably, the outer diameter of the arc-shaped plate is smaller than the diameter of the filter tube.

[0040] Furthermore, by adjusting the diameter of the arc-shaped plate, the second disc, the arc-shaped plate, and the first disc can be fully inserted into the filter tube. Here, the diameter of the first disc should also be smaller than the inner diameter of the filter tube. At the same time, the internal structure of the filter tube is fully considered so that the diameter specification can be set as needed to ensure full insertion. In this way, the space occupied by the gas can be reduced during pulse backflushing. This reduction ensures the impact force of the backflushing gas, so as to effectively clean the dust and impurities attached to the filter tube.

[0041] The beneficial effects of this invention are:

[0042] 1. The pulse gas delivery pipe is a hollow, bent structure. The vertical end of the pulse gas delivery pipe is fixedly connected to and passes through the gas supply pipe so that gas can enter the pulse gas delivery pipe through the gas supply pipe. At the same time, the horizontal end of the pulse gas delivery pipe is arc-shaped so that it can be fixed to the arc plate. Openings or holes are provided on both sides of the horizontal end of the pulse gas delivery pipe. The curvature of the openings or holes is the same as the curvature of the arc plate 23. Through this design, the high-pressure gas can move inertially along the arc of the openings or holes to reduce the direct impact on the filter tube.

[0043] The opening facilitates gas flow, allowing the gas cleaned by the filter tube to quickly pass through the closed partition and enter the extraction chamber.

[0044] 2. The sum of the angles of the multiple sealing arc plates is 360° or greater. This ensures that when the multiple sealing arc plates rotate, they can form a circular tube structure, guaranteeing the sealing of the tube and reducing gas leakage. For example, in actual operation, a sealing gasket can be placed on one side of the sealing arc plate in the direction of rotation. When the sealing arc plate rotates under the impact of high-pressure gas, the sealing gasket and the arc plate will come into contact to seal.

[0045] The sealing mechanism described above reduces the space occupied by the gas output from the pulse gas delivery pipe;

[0046] 3. By adjusting the diameter of the arc-shaped plate, the second disc, the arc-shaped plate, and the first disc can be fully inserted into the filter tube. The diameter of the first disc should also be smaller than the inner diameter of the filter tube. At the same time, the internal structure of the filter tube should be fully considered so that the diameter specification can be set as needed to ensure full insertion. In this way, the space occupied by the gas can be reduced during pulse backflushing. This reduction ensures the impact force of the backflushing gas, so as to effectively clean the dust and impurities attached to the filter tube. Attached Figure Description

[0055] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0056] Reference Figure 1-7An environmentally friendly pulse back-blowing vacuum cleaner for grinding paper core plugs includes a dust removal equipment component 1. An air extraction chamber 7 is fixed to one side of the dust removal equipment component 1. A sealing partition 15 is sealed and fixed between the dust removal equipment component 1 and the air extraction chamber 7. A negative pressure power mechanism is installed at the lower end of the air extraction chamber 7. A power connector 10 is provided on the negative pressure power mechanism. A directional extraction mechanism is installed at one end of the power connector 10. The directional extraction mechanism is installed at the lower end of the dust removal equipment component 1. The dust removal equipment component 1 is a vacuuming device. Unlike conventional vacuuming devices, this invention uses an inclined tube design, which allows for better contact with dust to purify the air. The negative pressure power mechanism provides power for the operation of corresponding components and controls the direction of gas flow, preventing the gas containing dust in the grinding equipment 16 from scattering randomly.

[0057] Impurities can be discharged in a targeted manner through the extraction mechanism;

[0058] Furthermore, a control device is installed on the dust removal equipment component 1, which can be controlled by a PLC. According to the actual situation, the staff can output the corresponding program so that the automated components in this invention can operate according to the program. At the same time, the corresponding power supply connection and supporting equipment are installed to ensure that the automated components in this invention can operate.

[0059] In this embodiment, a diagonal support frame 12 is provided on the side of the dust removal equipment component 1 away from the extraction chamber 7. Multiple filter tubes 11 are installed at equal intervals on the diagonal support frame 12. One end of the filter tube 11 passes through the closed partition 15 and extends into the extraction chamber 7. A high-pressure gas conveying mechanism is installed on both the extraction chamber 7 and the dust removal equipment component 1. Multiple gas supply pipes 21 are provided on the high-pressure gas conveying mechanism. All gas supply pipes 21 pass through the extraction chamber 7 and extend into the multiple filter tubes 11 respectively. The diagonal support frame 12 allows the filter tubes 11 to be tilted so that the filter tubes 11 can fully contact the dust-laden gas. In actual operation, the filter tubes 11 can be staggered so that the multiple filter tubes 11 can fill the space inside the dust removal equipment component 1 when viewed from above, ensuring that the downward-flowing gas can fully contact the filter tubes 11, thereby improving the purification effect.

[0060] In this embodiment, a first disc 19 is fixed to one end of the air supply pipe 21. An aeration mechanism is installed on the first disc 19. An impact mechanism is installed inside the air supply pipe 21. A fixed shaft 24 is provided on the impact mechanism. A second disc 25 is fixed to one end of the fixed shaft 24. Multiple sealing arc plates 26 are fixed on the second disc 25. Multiple arc plates 23 are fixed on the first disc 19. The aeration mechanism and the arc plates 23 are connected. The aeration mechanism can make the gas quickly impact the filter tube 11 under pulse conditions so that the impurities attached to the filter tube 11 can be cleaned. At the same time, the impact mechanism can convert the impact force of the high-pressure gas into the force of component operation so that the space occupied by the gas is reduced during pulse backflushing, so that the gas can fully backflush the filter tube 11. In actual operation, the second disc 25, the fixed shaft 24, the arc plate 23, the sealing arc plate 26, and the pulse air supply pipe 20 all extend into the corresponding filter tube 11.

[0061] In this embodiment, a suction pipe 3 is installed on one side of the upper end of the dust removal equipment component 1, and one end of the suction pipe 3 is connected to a grinding device 16. The grinding device 16 can perform grinding operations on the paper core plug. This operation is a common technical means in the field and does not need to be explained again. During the grinding process, a large amount of dust will be generated inside the grinding device 16. Through the action of the suction pipe 3, the air and dust inside the grinding device 16 can enter the dust removal equipment component 1 so that the dust removal equipment component 1 can purify the gas, collect the dust, and discharge the purified gas.

[0062] In this embodiment, the negative pressure power mechanism includes a discharge pipe 17 fixed at the lower end of the suction chamber 7. A motor assembly 8 is installed on one side of the discharge pipe 17. A suction assembly 9 is fixed at the end of the output shaft of the motor assembly 8. The suction assembly 9 is disposed through the suction chamber 7 and the discharge pipe 17. One end of the power connector 10 is rotatably sleeved on the side of the lower end of the suction chamber 7 away from the discharge pipe 17. The other end of the power connector 10 passes through the suction chamber 7 and is connected to the suction assembly 9. The motor assembly 8 can drive the suction assembly 9 to rotate. A fan blade mechanism is installed on the suction assembly 9. Through the joint rotation of the suction assembly 9 and the motor assembly 8, the fan blade drives the gas to flow from the suction chamber 7 toward the discharge pipe 17. This causes the gas outside the back-blowing to flow along the edge grinding equipment 16 into the suction pipe 3, the dust removal equipment assembly 1, the filter pipe 11 and the suction chamber 7, and finally out through the discharge pipe 17.

[0063] During the above process, the dust-laden gas inside the edge grinding equipment 16 can be fully purified through the filter tube 11;

[0064] Meanwhile, the air extraction assembly 9 and the power connection 10 are set by the staff according to the actual situation, that is, the air extraction assembly 9 and the power connection 10 can rotate relative to the discharge pipe 17 and the air extraction chamber 7, and the motor assembly 8 can drive the air extraction assembly 9 to rotate.

[0065] In this embodiment, the directional extraction mechanism includes a discharge pipe 2 that runs through the lower end of the dust removal equipment assembly 1. An auger output component 13 is installed at the lower end of the discharge pipe 2, and an electrically controlled valve 14 is installed on one side of the lower end of the auger output component 13. The auger output component 13 is connected to the power connector 10. When the power connector 10 drives the auger output component 13 to rotate, the auger component inside the auger output component 13 can rotate. By controlling the rotation direction of the auger component and the setting position of the electrically controlled valve 14, impurities can be discharged through the electrically controlled valve 14.

[0066] In actual operation, the electrically controlled valve 14 can be connected to the supporting equipment to ensure the centralized collection of impurities and prevent impurities from scattering.

[0067] In this embodiment, the high-pressure gas delivery mechanism includes a high-pressure gas supply component 4 installed on the upper end of the dust removal equipment component 1. One end of the high-pressure gas supply component 4 is connected to a high-pressure gas storage tank 5, which is fixed to one side of the extraction chamber 7. Multiple edge grinding devices 16 are installed through both ends of the high-pressure gas storage tank 5, and multiple gas supply pipes 21 are respectively installed through the multiple edge grinding devices 16. An electric control valve 27 is installed on the gas supply pipe 21. A gas pressure detection component 6 is installed on one side of the lower end of the high-pressure gas storage tank 5. The high-pressure gas supply component 4 can extract gas and deliver it into the high-pressure gas storage tank 5, forming a high-pressure state inside the high-pressure gas storage tank 5. At the same time, the high-pressure gas storage tank 5 and the corresponding components connected to it all use high-pressure components to ensure installation.

[0068] The air pressure detection component 6 can detect the gas pressure value in the high-pressure gas storage tank 5 and the edge grinding equipment 16, and can upload the gas pressure value so that the control component on the dust removal equipment component 1 can receive and process it. When the pressure reaches the set pressure value, it can control the electric control valve 27 to realize gas flow so as to perform pulse backflushing.

[0069] In actual operation, the control equipment on the dust removal equipment component 1 can output the corresponding program according to the actual situation, and the dust removal equipment component 1 is equipped with matching components, such as power connection and equipment control components. The components are assembled using existing technology to ensure that each automated component can work according to the program settings and program control. This is a common technical means in this field.

[0070] The pressure inside the high-pressure gas storage tank 5 and the edge grinding equipment 16 is the same. The high-pressure gas supply component 4 pressurizes the gas, causing the gas pressure inside the high-pressure gas storage tank 5 and the edge grinding equipment 16 to rise. The gas pressure is detected by the gas pressure detection component 6. When the set gas pressure is reached, the electric control valve 27 can be controlled to allow the high-pressure gas to enter the pulse gas delivery pipe 20 through the gas supply pipe 21 for backflushing operation.

[0071] In this embodiment, the aeration mechanism includes multiple pulse air delivery pipes 20 that are equally spaced and pass through the air supply pipe 21. The multiple pulse air delivery pipes 20 are respectively fixed on multiple arc plates 23, and the multiple pulse air delivery pipes 20 are all fixedly connected to the first disc 19.

[0072] Multiple openings 22 are evenly spaced on the first disc 19, and the multiple openings 22 and multiple pulse gas delivery pipes 20 are arranged alternately. The pulse gas delivery pipe 20 is hollow and bent. The vertical end of the pulse gas delivery pipe 20 is fixedly connected to and passes through the gas supply pipe 21 so that gas can enter the pulse gas delivery pipe 20 through the gas supply pipe 21. At the same time, the horizontal end of the pulse gas delivery pipe 20 is arc-shaped so that it can be fixed on the arc plate 23. Openings or holes are opened on both sides of the horizontal end of the pulse gas delivery pipe 20. The arc of the openings or holes is the same as the arc of the arc plate 23. Through this arrangement, the high-pressure gas can move inertially along the arc of the openings or holes so as to reduce the direct impact on the filter tube 11.

[0073] The opening 22 facilitates gas flow, allowing the gas cleaned by the filter tube 11 to quickly pass through the closed partition 15 and enter the extraction chamber 7.

[0074] In this embodiment, the impact mechanism includes a fixed frame 29 fixed inside the air supply pipe 21. One end of the fixed frame 29 is rotatably sleeved with a linkage shaft 28 with turbine blades. One end of the linkage shaft 28 with turbine blades is fixedly connected to the fixed shaft 24. A reset mechanism is provided between the linkage shaft 28 with turbine blades and the air supply pipe 21. The linkage shaft 28 with turbine blades is installed inside the air supply pipe 21, and the fixed frame 29 can ensure the stability of the installation of the linkage shaft 28 with turbine blades, thereby ensuring the stability of the fixed shaft 24. At the same time, in actual operation, the linkage shaft 28 with turbine blades can be configured with vortex blades to ensure that the high-pressure gas entering the air supply pipe 21 can impact the blades, so that the linkage shaft 28 with turbine blades can rotate in a specific direction. The configuration scheme is common knowledge in the art and does not need to be disclosed again.

[0075] The linkage shaft 28 with turbine fan blades and the action of high-pressure gas enhance the backflushing cleaning effect during pulse backflushing, and ensure the stable flow of purified gas after backflushing cleaning is completed under the action of the reset mechanism.

[0076] In this embodiment, the reset mechanism includes a linkage plate 18 fixed on a linkage shaft 28 with turbine blades. A tension spring 30 is fixed to the inner wall of the linkage plate 18 and the air supply pipe 21. When the vortex blades on the linkage shaft 28 with turbine blades rotate under the impact of high-pressure gas, the linkage plate 18 can drive the tension spring 30 to move, causing the tension spring 30 to be stretched. When the high-pressure gas stops impacting, the tension spring 30 can pull the linkage plate 18 and the linkage shaft 28 with turbine blades to reset, so that the linkage shaft 28 with turbine blades can drive the sealing arc plate 26 to reset through the fixed shaft 24 and the second disc 25. This allows the space inside the filter tube 11 to be unobstructed, facilitating rapid gas flow, so that the purified gas can enter the side of the closed partition 15 away from the suction pipe 3 through the filter tube 11.

[0077] In this embodiment, the outer sides of multiple sealing arc plates 26 respectively abut against the inner sides of multiple arc plates 23. The sealing arc plates 26 and arc plates 23 have the same angle. The inner walls of multiple arc plates 23 and the outer walls of multiple sealing arc plates 26 together form a circle. The center of the circle formed by the inner walls of multiple arc plates 23 and the outer walls of multiple sealing arc plates 26 overlaps with the axis of the fixed shaft 24. The sum of the angles of multiple sealing arc plates 26 and multiple arc plates 23 is 360° or greater than 360°, ensuring that when multiple sealing arc plates 26 rotate, multiple sealing arc plates 26 and multiple arc plates 23 can form a circular tube structure, and ensuring the sealing performance of the circular tube and reducing gas leakage. For example, in actual operation, a sealing gasket can be set on one side of the rotation direction of the sealing arc plate 26. When the sealing arc plate 26 rotates under the impact of high pressure gas, the sealing gasket and the arc plate 23 can abut against each other to seal.

[0078] The sealing mechanism described above reduces the space occupied by the gas output from the pulse gas delivery pipe 20.

[0079] Furthermore, in actual operation, the friction between the sealing arc plate 26 and the arc plate 23 is reduced according to existing technology, so as to ensure that the sealing arc plate 26 can rotate under the action of the fixed shaft 24 and the second disc 25. That is, when the high-pressure gas impacts the linkage shaft 28 with turbine blades, the linkage shaft 28 with turbine blades can pull the tension spring 30, and at the same time drive the fixed shaft 24 and the second disc 25 to rotate, so that multiple sealing arc plates 26 and multiple arc plates 23 form a circular tube structure.

[0080] In this embodiment, the outer diameter of the arc plate 23 is smaller than the diameter of the filter tube 11. The diameter of the arc plate 23 is set so that the second disk 25, the arc plate 23 and the first disk 19 can be fully inserted into the filter tube 11. Here, the diameter of the first disk 19 is also smaller than the inner diameter of the filter tube 11. At the same time, the internal structure of the filter tube 11 is fully considered so that the diameter specification can be set as needed to ensure that it can be fully inserted. In this way, the space occupied by the gas can be reduced during pulse backflushing. This reduction ensures the impact force of the backflushing gas so as to fully clean the dust and impurities attached to the filter tube 11.

[0081] In this invention, the second disc 25, the fixed shaft 24, the arc plate 23, the sealing arc plate 26, and the pulse gas delivery pipe 20 all extend into the corresponding filter pipe 11;

[0082] The air pressure detection component 6 detects and understands the air pressure. When the set air pressure is reached, it controls the electronic control valve 27 to allow high-pressure gas to enter the pulse gas delivery pipe 20 through the air supply pipe 21. The high-pressure gas entering the air supply pipe 21 impacts the blades, causing the linkage shaft 28 with turbine blades to rotate in a specific direction. As the linkage shaft 28 with turbine blades rotates, it drives the fixed shaft 24 to rotate. The fixed shaft 24 drives the sealing arc plate 26 to rotate. The inner wall of the sealing arc plate 26 and the fixed shaft 24 are both fixed with a bracket to ensure synchronous rotation. Multiple sealing arc plates 26 and multiple arc plates 23 can form a closed tube, reducing the space occupied by the backflushing gas, allowing the gas to backflush and clean the filter tube 11. The cleaned dust is discharged through the auger output component 13 and the electronic control valve 14.

[0083] The purified gas can be discharged through the extraction chamber 7 and the discharge pipe 17, preventing the dust-laden air inside the edge grinding equipment 16 from drifting away randomly and improving the environmental protection effect.

[0084] 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.
