[0056] The application will be further described below with reference to the drawings and specific embodiments. It is to be noted that the technical features involved in the various embodiments of the application described below can be combined with each other as long as there is no conflict. The embodiments described below with reference to the drawings are exemplary and are intended to explain the application, but cannot be understood as limiting the application.

[0057] As shown in the drawings, Figures 1-2 The present disclosure provides a backflushing dust removal device 1, which comprises a support 11, a filter element 12, and at least one air knife 13.

[0058] In some embodiments, the filter element 12 can comprise a filter body 121 in the shape of a cylinder and a bottom plate 122. The filter body 121 has a hollow accommodating cavity formed inside, and the filter body 121 is sleeved outside the support 11 and has a space between the support 11. That is, the support 11 is arranged in the accommodating cavity and is spaced apart from the inner side wall of the filter body 121. The bottom plate 122 is arranged at the bottom of the filter body 121 and is connected to the bottom surface of the filter body 121, and the support rod is connected to the bottom plate 122.

[0059] The end of the accommodating cavity away from the bottom plate 122 forms an outlet, and the filter element 12 is used for allowing external gas to enter the accommodating cavity after being filtered by the filter body 121, and the filtered gas exits the accommodating cavity through the outlet.

[0060] Specifically, the filter body 121 in the filter element 12 is used for filtering external gas to remove particulate matters such as dust in the gas, thereby purifying the gas.

[0061] In some embodiments, the central axis of the support 11 can coincide with the central axis of the filter element 12.

[0062] In some embodiments, the bottom plate 122 can be rotatably connected to the support 11.

[0063] For example, the backflushing dust removal device 1 in the embodiments of the present disclosure can comprise an end face bearing seat 14, which is located in the accommodating cavity and is fixed to the bottom plate 122. The bottom end of the support 11 is connected to the end face bearing seat 14, and the support 11 can rotate relative to the end face bearing seat 14.

[0064] In some embodiments, the reverse-flushing dust collector 1 may further include a bearing mounting base 15, which is located outside the receiving cavity and fixed to the top of the filter element 12. A support member 11 may protrude upwards from the filter element 12 so that its top is connected to the bearing mounting base 15. The support member 11 is rotatable relative to the bearing mounting base 15.

[0065] In some embodiments, the air knife 13 is disposed within the receiving cavity and extends along the axial direction of the filter element 12. The air knife 13 is connected to the support member 11. Figure 3 As shown, the air knife 13 in this embodiment may include a housing 131, within which a high-pressure chamber is formed. An air inlet 132 and a nozzle 133 are formed on the housing 131. Both the nozzle 133 and the air inlet 132 are connected to the high-pressure chamber. The air inlet 132 is used to receive compressed gas, and the nozzle 133 extends along the length of the housing 131. After compressed gas is introduced into the air knife 13 through the air inlet 132, the gas leaves the high-pressure chamber through the nozzle 133 and forms a thin airflow sheet that blows towards the inner wall of the filter element 12. The air knife 13 can rotate around the inner wall of the filter element 12 under the action of the airflow sheet.

[0066] It should be noted that the air knife 13 in this embodiment is an airflow processing device. When compressed gas enters the high-pressure chamber, the gas leaves the high-pressure chamber through the thin nozzle 133, thereby forming a uniform airflow sheet in the length direction of the air knife 13.

[0067] For example, the high-pressure chamber can compress the gas at a ratio of 40:1, minimizing airflow velocity loss while maximizing pressure, thereby generating a thin sheet of airflow with strong impact and low shear force, which can quickly remove dust and other particles from the surface of the filter element 12 at high wind speed and multiple frequencies.

[0068] For example, the air knife 13 can be placed entirely within the receiving cavity. The air knife 13 can be spaced apart from the inner wall of the filter body 121. The length of the air knife 13 can be slightly less than the height of the filter body 121. The bottom of the air knife 13 near the bottom plate 122 is spaced apart from the bottom plate 122. This maximizes the contact area between the airflow sheet formed by the air knife 13 and the inner wall of the filter body 121, while also reducing the risk of friction between the air knife 13 and the filter element 12, thereby extending the service life of the air knife 13 and the filter element 12.

[0069] The air inlet 132 on the air knife 13 can be located at at least one end of the air knife 13 along its length, that is, the air inlet 132 is located on the end of the air knife 13 near the base plate 122 and / or on the end of the air knife 13 away from the base plate 122.

[0070] In some embodiments, the line between the intersection of the airflow sheet and the inner side wall of the filter body 121 and the center of the filter body 121 is not parallel to the airflow sheet.

[0071] It should be noted that the intersection of the airflow sheet and the inner side wall of the filter body 121 refers to the intersection between the airflow blown by the nozzle 133 and the inner side wall of the filter body 121 when the air knife 13 is at a certain position. The line between the intersection and the center of the filter body 121 is the radius of the filter body 121 at the intersection.

[0072] That is, when the air knife 13 is at a certain position, the filter body 121 has an intersection between the airflow blown by the nozzle 133 and the inner side wall of the filter body 121, and the intersection is located at a certain radius of the filter core 12, and the radius is not parallel to the airflow sheet. At this time, the airflow blown by the nozzle 133 can act on the inner side wall of the filter body 121, and the reaction force generated by the airflow can also drive the air knife 13 to rotate around the inner side wall of the filter body 121 for a full cycle, so as to use the high-speed wind pressure formed by the air knife 13 to blow off the particles adhering to the surface of the filter body 121, reduce the risk of plugging of the filter core 12, ensure the sustainable and stable operation of the filter core 12, prolong the service life of the filter core 12, and reduce the maintenance cost. In addition, the disclosed embodiment utilizes the reaction force generated by the airflow sheet in the accommodating cavity to drive the air knife 13 to rotate, which also reduces the support of external power, thereby reducing the energy consumption of the back-blowing dust removal equipment 1.

[0073] As shown in Figure 4 In some embodiments, the back-blowing dust removal equipment 1 can include a connecting piece 111, both ends of which are connected with the support 11 and the air knife 13 respectively, so as to fix the air knife 13 on the support 11.

[0074] For example, the connecting piece 111 in the present disclosure can have a bending shape as a whole, and the connecting piece 111 can include a first bending part, a second bending part and a third bending part which are sequentially connected between the air knife 13 and the support 11. The first bending part is connected with the air knife 13, and the first bending part is not parallel to the second bending part. The third bending part is connected with the support 11, and the second bending part is not parallel to the third bending part. That is, the connecting piece 111 as a whole is not parallel to the radius of the filter core 12.

[0075] The present disclosure can adjust the bending angle of any one of the first bending part, the second bending part and the third bending part to adjust the installation angle of the air knife 13, so that the airflow sheet formed by the air knife 13 can blow off the particles adhering to the surface of the filter core 12, and at the same time, the reaction force generated by the airflow sheet can drive the air knife 13 to rotate around the inner side wall of the filter core 12.

[0076] In some embodiments, the present disclosure may also provide one or more ventilation holes on the connector 111, the ventilation holes being disposed through the connector 111 to reduce the resistance when the connector 111 rotates.

[0077] For example, this disclosure may provide a ventilation hole on the third bend.

[0078] In some embodiments, the reverse-flushing dust collector 1 may include two air knives 13, located on opposite sides of the support member 11, with one air knife 13 rotated 180° to coincide with the position of the other air knife 13. This embodiment of the present disclosure enhances the impact of the reverse-flushing dust collector 1 on the inner wall of the filter body 121 by providing two air knives 13 within the filter element 12, thereby increasing the rate at which particulate matter detaches from the surface of the filter element 12 and improving the cleaning efficiency of the filter element 12.

[0079] like Figure 2 As shown in this embodiment, the pulse backflush device may be provided with two connectors 111 to fix the two air knives 13 onto the support member 11 respectively.

[0080] like Figure 4 As shown, in some embodiments, a collar 112 can be provided on the outer periphery of the support member 11. The collar 112 is disposed on the support member 11, and the connector 111 can be connected to the support member 11 through the collar 112, thereby reducing the damage to the connector 111 caused by the force during the rotation of the connector 111. In addition, the collar 112 in this disclosure can be detachably connected to the support member 11, which not only realizes the modular installation of the reverse-flushing dust collector 1, but also facilitates the maintenance and replacement of the connector 111 through disassembly, thereby improving the maintenance efficiency and convenience of the reverse-flushing dust collector 1.

[0081] In some embodiments, a retaining ring may be provided at the top of the filter body 121, the retaining ring being disposed around the outer periphery of the filter body 121 and connected to the filter body 121. The outer periphery of the retaining ring is provided with a plurality of protrusions arranged in an array at intervals.

[0082] like Figures 1-2 As shown, in some embodiments, the top sleeve of the filter body 121 may also be provided with a retaining sleeve 16, which may include a cover plate and multiple retaining claw structures. The cover plate is located on the side of the filter body 121 opposite to the bottom plate 122, and the cover plate is arranged around the outer side wall of the filter element 12, forming a through hole communicating with the receiving cavity.

[0083] For example, the cover plate can be an annular structure, with the circular hole formed by the annular structure being a through hole. Multiple claw structures are arranged in an array at intervals on the outer periphery of the cover plate and connected to the side of the cover plate near the base plate 122. The bearing mounting seat 15 is connected to the top surface of the cover plate, and the support member 11 can be connected to the bearing mounting seat 15 through the through hole.

[0084] It should be noted that the gap between the two adjacent protruding structures is not less than the claw structure, so that the claw structure can be sleeved on the clasp through the gap between the protruding structures, and then the clamping sleeve 16 can be rotated to make the claw structure correspondingly clamped with the protruding structure, thereby realizing the fixed connection of the clamping sleeve 16 and the clasp.

[0085] The clasp and the clamping sleeve 16 corresponding to the clasp are arranged on the top of the filter body 121, so as to provide support for the bearing mounting seat 15, thereby facilitating the installation of the bearing mounting seat 15. Meanwhile, the bearing mounting seat 15 is installed on the filter element 12 through the clasp and the clamping sleeve 16, so as to improve the stability of the connection between the bearing mounting seat 15 and the filter element 12. In addition, the bearing mounting seat 15 is installed on the clamping sleeve 16, so that the damage of the filter element 12 caused by the force generated when the air knife 13 and the support 11 rotate can be reduced by the clamping sleeve 16, thereby prolonging the service life of the filter element 12.

[0086] In some embodiments, the clasp and the clamping sleeve 16 are detachably connected. When the clamping sleeve 16 is damaged, the clamping sleeve 16 can be separated from the clasp, so as to repair or replace a new clamping sleeve 16, thereby facilitating the repair and reducing the repair and replacement cost of the reverse blow dust removal equipment 1.

[0087] As shown in Figure 5 In some embodiments, the support 11 is hollow inside, and the reverse blow dust removal equipment 1 can further include a compressed gas inlet pipeline 17 and a plurality of internal air pipes. The compressed gas inlet pipeline 17 is arranged outside the filter element 12 and connected with the top of the support 11, so as to deliver compressed gas into the support 11. The plurality of internal air pipes are uniformly arranged on the support 11, one end of each internal air pipe is in communication with the support 11, and the other end is in communication with the air inlet 132 on the air knife 13. The compressed gas inside the support 11 can enter the high-pressure cavity in the air knife 13 through the internal air pipes, and then form a gas flow sheet at the nozzle 133.

[0088] As shown in Figure 5 In some embodiments, the reverse blow dust removal equipment 1 can further include a pulse electromagnetic valve switch 18 arranged on the compressed gas inlet pipeline 17. When the pulse electromagnetic valve switch 18 is opened, the compressed gas in the compressed gas inlet pipeline 17 can be delivered to the support 11, so as to realize the gas supply to the air knife 13. When the pulse electromagnetic valve switch 18 is closed, the compressed gas inlet pipeline 17 can stop supplying gas to the support 11. That is, the pulse electromagnetic valve switch 18 is arranged on the compressed gas inlet pipeline 17, so as to control the delivery of the compressed gas into the support 11 through the pulse electromagnetic valve switch 18.

[0089] It should be noted that the present disclosure can time the pulse electromagnetic valve switch 18 to enable the back-blowing dust removal device 1 to automatically remove the accumulated particles on the surface of the filter element 12 at a regular time, thereby prolonging the service life of the filter element 12 and reducing the maintenance cost of the filter element 12.

[0090] As shown in Figure 1 and Figure 2 In some embodiments, the back-blowing dust removal device 1 can further include a rotary joint 19, one end of which is sleeved on the top of the support 11, and the other end is in communication with the compressed gas inlet pipeline 17. The rotary joint 19 and the compressed gas inlet pipeline 17 are relatively fixed, and the support 11 can rotate relative to the rotary joint 19. By providing the rotary joint 19, the connection between the support 11 and the compressed gas inlet pipeline 17 can be achieved, and the sealing of the connection between the support 11 and the compressed gas inlet pipeline 17 can be improved, so that the compressed gas inlet pipeline 17 can effectively deliver gas to the support 11, and energy loss can be reduced.

[0091] As shown in Figure 5 and Figure 6 The present disclosure further provides a back-blowing dust removal system device 2, which can include a box 21 and at least one back-blowing dust removal device 1 as described above, and the back-blowing dust removal device 1 is arranged in the box 21. Wherein, the box 21 can form a fan chamber, a negative pressure chamber and an air purification chamber arranged in sequence from top to bottom. The gas containing dust and other particles is filled into the box 21, and after the particles in the gas are removed by the back-blowing dust removal device 1, the gas is discharged out of the box 21, which can purify the gas and collect the particles in the box 21.

[0092] Specifically, the fan chamber, the negative pressure chamber and the air purification chamber in the present disclosure are in communication with each other, and the box 21 is provided with at least one air inlet on the region corresponding to the air purification chamber, so that the external gas can enter the box 21. The air purification chamber can be used to place the back-blowing dust removal device 1 to purify the gas entering the box 21. A fan is arranged in the fan chamber to generate suction. The negative pressure chamber forms a negative pressure area under the action of the suction generated by the fan, so that the gas in the air purification chamber below can be extracted, and the purified gas can be delivered to the fan chamber. The box 21 is provided with at least one air outlet on the region corresponding to the fan chamber, so that the gas purified in the air purification chamber can be discharged to the outside of the box 21 through the negative pressure chamber and the air outlet in sequence. The external gas can be circulated into the box 21 for purification to reduce the content of particles in the external gas.

[0093] It should be noted that the back-blowing dust removal system device 2 in the present disclosure can be used to purify waste gas such as welding fume.

[0094] For example, the back-blowing dust removal system device 2 can be used in the production process of the container to purify the large amount of welding fume and waste gas generated in the process of combining the welding material with the base material, reduce the concentration of the welding fume and waste gas in the air, and thus optimize the welding working environment and maintain the health of the welder.

[0095] As shown in Figure 5 some embodiments, the back-blowing dust removal system device 2 can further include a dust collecting device located at the bottom of the back-blowing dust removal device 1. The dust collecting device includes a plurality of louvers 221 located in the box 21. The plurality of louvers 221 are laid parallel to the bottom surface of the box 21 away from the fan chamber, and the opposite ends of the length direction of the louver 221 are connected with the side circumferential surface of the box 21.

[0096] For example, the bottom of the box 21 can be provided with a louver outer frame 222, which is arranged around the side circumference of the box 21 and is fixedly connected with the box 21. The opposite ends of the length direction of the plurality of louvers 221 are movably connected with the louver outer frame 222.

[0097] It should be noted that the louver 221 has a closed state and an open state. In the closed state, the plurality of louvers 221 are seamlessly connected with each other and with the side circumferential surface of the box 21. That is, the plurality of louvers 221 can seal the bottom of the box 21, so that the particulate matter separated from the gas can be collected in the box 21, and the problem of secondary pollution of the external gas caused by the escape of the particulate matter from the box 21 can be improved. When the louvers 221 are driven to open, the plurality of louvers 221 rotate to separate from each other.

[0098] Specifically, when the louver 221 is switched from the closed state to the open state, the louver 221 can be switched from the flat state to the side-up state, and the louver 221 is rotated by 90°, so that a gap is formed between the adjacent two louvers 221 and between the louver 221 and the side circumferential surface of the box 21, so as to uniformly discharge the particulate matter from the box 21 to maintain the cleanliness of the inside of the box 21. However, the louver 221 can be rotated by an angle other than 90° when it is switched from the closed state to the open state, which can also facilitate the discharge of the particulate matter from the box 21, and this angle is also included in the embodiments of the present disclosure, which is not specifically exemplified here.

[0099] For example, when the back-blowing dust removal system device 2 is used in the welding working environment, the louvers 221 can be in the closed state during the welding process, and the louvers 221 can be opened when the welder finishes the welding work to uniformly discharge the collected particulate matter. When the back-blowing dust removal system device 2 is started again, the louvers 221 are switched to the closed state again to prevent the particulate matter in the dust collecting element 23 from being carried by the airflow to the filter element 12 and causing the filter element 12 to be blocked.

[0100] As shown in Figure 5 and Figure 6 In some embodiments, a driving source 223 can be arranged on the box 21 to drive the louvers 221 to switch between the closed state and the open state.

[0101] Specifically, the driving source 223 can be arranged outside the box 21 for easy maintenance. The driving source 223 can be a linear motion driving element such as a pneumatic cylinder or an electric cylinder.

[0102] As shown in Figure 5 In some embodiments, the dust collection device can further include a dust collection member 23 formed with a dust collection groove with an opening facing upward, and the dust collection member 23 is arranged outside the box 21 and detachably connected to the bottom of the box 21.

[0103] Specifically, the opening of the dust collection groove can be flush with the bottom surface of the box 21 away from the fan chamber, and the orthographic projection of the box 21 on the dust collection member 23 can coincide with the dust collection groove. After the louvers 221 are opened, dust and other particulate matter can fall into the dust collection groove, which can facilitate the collection of particulate matter while the dust collection member 23 can achieve secondary sealing of the bottom of the box 21, thereby improving the problem of particulate matter escaping from the box 21 due to poor sealing between the louvers 221 and causing secondary pollution to external air.

[0104] It should be noted that the dust collection member 23 can be a drawer type structure, and the dust collection member 23 is slidingly connected to the box 21, and the dust collection member is pulled out from the bottom of the box 21 by horizontal pulling, so that the particulate matter in the dust collection member 23 can be easily removed.

[0105] In some embodiments, the box 21 can be provided with a plurality of air inlets on the region corresponding to the air purification chamber, so that when the back-flushing dust removal system device 2 is installed in any orientation, at least one air inlet on the box 21 can facilitate the delivery of external air into the box 21.

[0106] For example, as shown in Figure 6 When the box 21 is a rectangular cuboid, one air inlet can be arranged on each of the four sides of the box 21.

[0107] As shown in Figure 6 In the embodiments of the present disclosure, an air inlet flange 24 can also be arranged on the box 21, the air inlet flange 24 is detachably connected to the box 21, and the orthographic projection of the air inlet flange 24 on the box 21 can cover at least the corresponding air inlet. The air inlet flange 24 is provided with a flange interface for introducing dust-containing air into the box 21. The present disclosure provides the air inlet flange 24 on the air inlet 132 to ensure that no leakage occurs during the delivery of external air into the box 21, thereby ensuring the safety and stability of air transmission.

[0108] It should be noted that when the box 21 is provided with multiple air inlets, multiple air inlet flanges 24 can be provided on the box 21, and the air inlet flanges 24 are provided one by one corresponding to the air inlets.

[0109] In addition, the box 21 can also be provided with an air inlet sealing plate for sealing the air inlet, the air inlet sealing plate is detachably connected with the box 21, and the orthographic projection of the air inlet sealing plate on the box 21 can cover at least the corresponding air inlet. When the backflushing dust removal system device 2 ends work, the air inlet can be sealed by using the air inlet sealing plate to reduce the external dust into the box 21, and reduce the risk of pollution in the box 21.

[0110] It should be noted that the air inlet sealing plate on the air inlet can be removed before using the backflushing dust removal system device 2, and the air inlet flange 24 is installed on the air inlet. When the dust removal ends, the air inlet flange 24 on the air inlet is removed, and the air inlet sealing plate is installed on the air inlet to enhance the sealing of the box 21.

[0111] When the box 21 is provided with multiple air inlets, multiple air inlet sealing plates can be provided on the box 21, and the air inlet sealing plates are provided one by one corresponding to the air inlets.

[0112] In some embodiments, the box 21 can include a lotus leaf door 25 and a support beam, one side of the lotus leaf door 25 is movably connected with the support beam. The worker can enter the box 21 by opening the lotus leaf door 25 to check the inside of the box 21, or to maintain the internal structure of the box 21.

[0113] For example, the box 21 can be set as a cuboid, and the box 21 includes four support beams extending along the vertical direction Y. At this time, the lotus leaf door 25 can be arranged on one side of the box 21, and the lotus leaf door 25 is movably connected with one of the support beams on the corresponding side.

[0114] The box 21 can be provided with one lotus leaf door 25, but is not limited thereto, and can also be provided with multiple lotus leaf doors 25.

[0115] For example, as shown in Figure 6 For example, as shown in

[0116] In some embodiments, the box door can be further provided with a display screen 26 and a switch button, the switch button can control the switch of the display screen 26, and the display screen 26 can be used to display the running state, parameter setting and fault information of each structure inside the back-blowing dust removal system device 2, so as to help the operator understand the real-time state of the equipment and perform corresponding operation.

[0117] In some embodiments, the back-blowing dust removal system device 2 can include a control cabinet 27, and the control cabinet 27 can include a power module for providing stable power supply to ensure the normal operation of the control cabinet 27. The control cabinet 27 in the present disclosure can be installed on the outer circumferential side of the box body 21 to facilitate the maintenance of the control cabinet 27.

[0118] In some embodiments, the back-blowing dust removal system device 2 can further include a plurality of moving wheels 28, and the plurality of moving wheels 28 are uniformly arranged on the bottom surface of the box body 21 away from the fan chamber. By arranging the moving wheels 28, the frictional force on the bottom surface of the box body 21 during movement can be reduced, so as to reduce the risk of damage to the box body 21. At the same time, the displacement of the box body 21 can be realized by using the moving wheels 28, so as to reduce the difficulty of transferring the back-blowing dust removal system device 2.
