Description

Technical Field

[0001] This application relates to the field of environmental air purification technology, and in particular to an integrated dust collector. Background Technology

[0002] In the field of new energy battery production, as the industry continues to develop, the requirements for the production environment are becoming increasingly stringent. Waste and dust are generated during the production process of new energy batteries, thus requiring dust collectors to provide a clean and hygienic environment for the manufacturing workshop.

[0003] In some explosion-proof dust collectors, the air inlet is connected to the air pipe. The fan draws the dust-laden gas into the dust-containing chamber, where it is then simply filtered by the filter paper on the outer surface of the filter cartridge. This allows the dust to adhere and the gas to flow. However, if the dust adheres to the filter cartridge for a long time, it will affect the filtration efficiency and effect. This will cause the fan to need to increase its power to transport the gas through the dust-accumulated filter cartridge. This will also cause the fan to generate a lot of noise, which will not only affect the working environment of the operators, but may also cause noise pollution to the surrounding environment. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an integrated dust collector.

[0005] The integrated dust collector provided in this application adopts the following technical solution: An integrated dust collector includes a primary dust collection chamber, a reverse-flushing chamber, and a fan chamber arranged sequentially in a horizontal direction. The primary dust collection chamber has a dust collection chamber at its bottom. A noise reduction chamber is located above the fan chamber, and a secondary dust collection chamber is located above the noise reduction chamber. An air inlet duct is located at the top of the primary dust collection chamber, and several filter cartridges are located below the air inlet duct, with the filter cartridges connected to the reverse-flushing chamber. A negative pressure fan is located in the fan chamber, with a first air duct at one end leading to the reverse-flushing chamber and a second air duct at the other end connecting to the noise reduction chamber. A pulse cleaning device is located in the reverse-flushing chamber, providing compressed air to backflush the filter cartridges, causing dust on the surface of the filter cartridges to fall into the dust collection chamber for cleaning. The noise reduction chamber reduces the noise of the negative pressure fan and transports the airflow to the secondary dust collection chamber, where the gas undergoes secondary dust removal before being discharged.

[0006] By adopting the above technical solution, the airflow is delivered to the primary dust removal chamber through the air inlet pipe, where it is filtered by the filter cartridge, causing dust to adhere to the filter cartridge. The pulse cleaning device in the back-blowing chamber removes the dust that has been attached to the filter cartridge for a long time, and the dust is then collected and cleaned in the dust collection chamber, thereby ensuring the long-term use of the filter cartridge. At the same time, it ensures the stable output power of the negative pressure fan and reduces the noise generated. Excess noise is reduced by the noise reduction chamber, and the secondary dust removal ensures the cleanliness of the gas.

[0007] Optionally, an interceptor plate is installed inside the air inlet duct, which divides the air inlet duct into a first air inlet area and a second air inlet area. The first air inlet area is connected to the second air inlet area, and the second air inlet area is connected to the filter chamber.

[0008] By adopting the above technical solution, the function of the interceptor plate is to divide the air inlet pipe into two areas, so that the sparks in the gas that follow into the first air inlet area can be intercepted by the interceptor plate and the bottom surface of the first air inlet area, thereby preventing the high-temperature sparks from entering the primary dust removal chamber and avoiding the sparks from affecting the normal use of the filter cartridge.

[0009] Optionally, the side of the air inlet duct is also provided with an inclined surface, the end of which is a primary dust removal chamber.

[0010] By adopting the above technical solution, the function of the inclined surface is that the sparks, after being intercepted, are in the form of granular spark debris, which can fall along the inclined surface with the airflow to the ash collection chamber for collection, thus avoiding accumulation in the air inlet pipe.

[0011] Optionally, the dust collection chamber includes a dust collection hopper, a suction pipe, an interception and opening / closing structure, and an air supply valve; the dust collection hopper is divided into two sections in the vertical direction, namely the first dust collection section and the second dust collection section, and the first dust collection section and the second dust collection section are separated by an interception and opening / closing structure; the suction pipe is located in the second dust collection section, and one end is connected to a suction device, and the other end is equipped with an air supply valve.

[0012] By adopting the above technical solution, the first dust collection section and the second dust collection section are separated by an intercepting opening and closing structure. When the dust or ash accumulated in the first dust collection section reaches a certain amount, the intercepting opening and closing structure is opened, allowing the dust or ash to fall uniformly into the second dust collection section. At this time, the intercepting opening and closing structure separates the first dust collection section and the second dust collection section, allowing the filter cartridge above the first dust collection section to continue filtering, while the dust or ash in the second dust collection section can be discharged through the suction pipe by using an external dust collection device and opening the air supply valve. At the same time, through the separating effect of the intercepting opening and closing structure, the dust discharge of the second dust collection section and the dust collection of the first dust collection section can be carried out simultaneously.

[0013] Optionally, the interception opening and closing structure includes a first opening and closing fan, a second opening and closing fan, an opening and closing bearing, a linkage shaft, a first linkage frame, a second linkage frame, and an opening and closing handle; four sets of opening and closing bearings are provided, and are installed in pairs opposite to each other on the inner wall of the first dust collection section; both the first and second opening and closing fans are provided with linkage shafts, and are pivotally connected to the opening and closing bearings through the linkage shafts; two sets of linkage shafts on one side of the first dust collection section extend outward through the corresponding bearing seats; a first linkage frame is installed on the two sets of linkage shafts located outside the first dust collection section, and a second linkage frame is hinged between the two first linkage frames; an opening and closing handle is provided on any linkage shaft with a first linkage frame.

[0014] By adopting the above technical solution, rotating the opening and closing handle causes the corresponding linkage shaft to rotate along the opening and closing bearing. Through the hinge action of the first linkage frame and the second linkage frame, the other linkage shaft is pushed to rotate, so that the first opening and closing fan and the second opening and closing fan rotate synchronously to realize the synchronous opening or closing of the first dust collection section, allowing dust or powder to fall into the second dust collection section. When the dust or powder in the second dust collection section begins to be discharged, the first opening and closing fan and the second opening and closing fan close, so that the first dust collection section can continue to collect dust or powder, and the second dust collection section discharges dust synchronously. The two can operate synchronously without interfering with each other.

[0015] Optionally, a flameless venting device is also provided on the top of the primary dust removal chamber.

[0016] By adopting the above technical solutions, the flameless venting device increases the safety factor in the primary dust removal chamber and improves the overall safety of use.

[0017] Optionally, a differential pressure sensor is installed in the backflush chamber.

[0018] By adopting the above technical solution, the differential pressure sensor constantly monitors the pressure difference changes in the backflushing chamber. When the pressure difference is lower than the standard value, an electrical signal is sent to activate the pulse cleaning device, thereby achieving the function of automatically cleaning the dust or powder accumulated on the filter cartridge.

[0019] Optionally, the inner wall of the fan room is also lined with sound-absorbing cotton.

[0020] By adopting the above technical solutions, the sound-absorbing cotton can be used to block the transmission of noise, making the environment quieter and improving comfort.

[0021] Optionally, several noise reduction panels are arranged vertically in the noise reduction chamber, and staggered air vents are provided between adjacent noise reduction panels to make the airflow flow in a Z-shaped path.

[0022] By adopting the above technical solution, when the gas carries the noise to the noise reduction plate, it directly contacts the noise reduction plate to provide noise reduction. After that, the gas continues to flow and enters another noise reduction plate from the vent for further noise reduction. Finally, the gas flows from the vent on the other side, forming a Z-shaped path, thereby further reducing the noise and improving the comfort of the environment.

[0023] Optionally, a high-efficiency filter element is installed in the secondary dust removal chamber.

[0024] By adopting the above technical solution, the high-efficiency filter element can intercept the gas transported by the noise reduction chamber in the secondary dust removal chamber, so that dust or dust particles such as dust particles in the gas can be further intercepted more finely.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Airflow is delivered to the primary dust removal chamber through the air inlet pipe, where it is filtered by the filter cartridges, causing dust to adhere to the filter cartridges. The pulse cleaning device in the back-blowing chamber removes the dust that has been attached to the filter cartridges for a long time, and the dust is collected and cleaned in the dust collection chamber, thus ensuring the long-term use of the filter cartridges. At the same time, it ensures the stable output power of the negative pressure fan and reduces the noise generated. Excess noise is reduced by the noise reduction chamber, and the secondary dust removal ensures the cleanliness of the gas. 2. The function of the interceptor plate is to divide the air inlet pipe into two areas, so that the sparks in the gas that follow the first air inlet area can be intercepted by the interceptor plate and the bottom surface of the first air inlet area, thereby preventing the high temperature sparks from entering the primary dust removal chamber and avoiding the sparks from affecting the normal use of the filter cartridge. 3. The purpose of the inclined surface is to allow the sparks to fall into the ash collection chamber along the inclined surface after being intercepted, so as to avoid them accumulating in the air inlet pipe. 4. The first and second dust collection sections are separated by an intercepting and opening structure. When the dust or powder accumulated in the first dust collection section reaches a certain amount, the intercepting and opening structure is opened, allowing the dust or powder to fall uniformly into the second dust collection section. At this time, the intercepting and opening structure separates the first and second dust collection sections, allowing the filter cartridge above the first dust collection section to continue filtering, while the dust or powder in the second dust collection section can be discharged through the suction pipe by using an external dust collection device and opening the air supply valve. At the same time, the separation effect of the intercepting and opening structure allows the dust discharge of the second dust collection section and the dust collection of the first dust collection section to be synchronized.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail below.

[0033] This application discloses an integrated dust collector.

[0034] An integrated dust collector, reference Figure 1 and Figure 2 As shown, it includes a primary dust removal chamber 1, a back-blowing chamber 2, and a fan chamber 3 arranged sequentially in a horizontal direction; the bottom of the primary dust removal chamber 1 is provided with a dust receiving chamber 4. The primary dust removal chamber 1 can perform the first dust removal on the gas. The gas first enters the primary dust removal chamber 1. After dust removal, the dust can fall to the dust receiving chamber 4 due to gravity and is stored in the dust receiving chamber 4. The back-blowing chamber 2 provides the back-blowing effect. A controller can be set outside the back-blowing chamber 2 to provide CNC operation of the entire dust removal chamber equipment.

[0035] A noise reduction chamber 5 is installed above the fan room 3, and a secondary dust removal chamber 6 is installed above the noise reduction chamber 5. The fan room 3 is driven by negative pressure, and the noise reduction chamber 5 provides noise reduction when the fan room 3 exhausts air to avoid excessive noise affecting the working environment. The secondary dust removal chamber 6 performs secondary filtration and dust removal on the airflow to improve the dust removal effect and cleanliness.

[0036] The primary dust removal chamber 1 is equipped with an air inlet pipe 11 at the top. Several filter cartridges 12 are installed in the primary dust removal chamber 1 below the air inlet pipe 11, and the filter cartridges 12 are connected to the back-flushing chamber 2. The air inlet pipe 11 is the initial conveying end of the gas conveying. After the gas enters the primary dust removal chamber 1 through the air inlet pipe 11, it is filtered by the filter cartridges 12. After the gas passes through the filter cartridges 12, it enters the back-flushing chamber 2. Then, the back-flushing chamber 2 conveys the gas collected by the several filter cartridges 12 to the fan room 3.

[0037] refer to Figure 3As shown, a negative pressure fan 31 is installed in the fan room 3. One end of the negative pressure fan 31 is provided with a first air duct 32 leading to the back-blowing chamber 2, and the other end is provided with a second air duct 33 connecting to the noise reduction chamber 5. The negative pressure fan 31 generates negative pressure in the back-blowing chamber 2 and the primary dust removal chamber 1, so that the gas can flow in the suction direction of the negative pressure fan 31, that is, from the air inlet duct 11 to the primary dust removal chamber 1, then enter the filter cartridge 12 and then enter the back-blowing chamber 2, and finally flow to the negative pressure fan 31 through the first air duct 32.

[0038] The back-blowing chamber 2 is equipped with a pulse cleaning device 21, which provides compressed air to back-blow the filter cartridge 12. As dust or grime is blocked on the surface of the filter cartridge 12 after the gas flows, the filtration effect is achieved. However, if dust or grime accumulates for a long time, it can easily cover the filter cartridge 12, reducing the filtration effect of the filter cartridge 12 and decreasing the gas flow. Therefore, the pulse cleaning device 21 uses compressed air to back-blow the filter cartridge 12, thereby removing the dust from the surface of the filter cartridge 12 and restoring the filter cartridge 12 to its initial state. The dust or grime on the surface of the filter cartridge 12 falls to the dust collection chamber 4 under the influence of gravity, where the dust collection chamber 4 provides for the accumulation and cleaning of dust.

[0039] The negative pressure fan 31 provides positive pressure to the noise reduction chamber 5 and the secondary dust removal chamber 6 through the second air duct 33, that is, the gas in the back-blowing chamber 2 is transported to the noise reduction chamber 5. After the gas is supplied to the second air duct 33, it enters the noise reduction chamber 5. The function of the noise reduction chamber 5 is to provide noise reduction for the negative pressure fan 31, and after noise reduction, the airflow is transported to the secondary dust removal chamber 6. The secondary dust removal chamber 6 removes dust from the gas a second time, making the gas clean and then discharging the gas.

[0040] Specifically, the airflow is delivered to the primary dust removal chamber 1 through the air inlet pipe 11, where it is filtered by the filter cartridge 12, causing dust to adhere to the filter cartridge 12. The pulse cleaning device 21 in the back-blowing chamber 2 removes the dust that has been attached to the filter cartridge 12 for a long time, and the dust is accumulated and cleaned by the dust receiving chamber 4, thereby ensuring the long-term use of the filter cartridge 12. At the same time, it ensures the stable output power of the negative pressure fan 31 and reduces the noise generated. Excess noise is reduced by the noise reduction chamber 5, and the cleanliness of the gas is ensured by the secondary dust removal.

[0041] Further reference Figure 4 As shown, the air inlet pipe 11 is equipped with an interceptor plate 111. The air inlet pipe 11 is a rectangular pipe with an inclined surface at the bottom. The interceptor plate 111 divides the air inlet pipe 11 into a first air inlet area 112 and a second air inlet area 113 in the vertical direction. The first air inlet area 112 is equipped with an air inlet, that is, the airflow enters the air inlet pipe 11 from the first air inlet area 112.

[0042] The first air intake area 112 is connected to the second air intake area 113, and the second air intake area 113 is connected to the filter chamber. Therefore, after the gas enters the first air intake area 112, it is transported to the second air intake area 113. The function of the interceptor plate 111 is to divide the air intake pipe 11 into two areas, so that the sparks that follow the gas into the first air intake area 112 can be intercepted by the interceptor plate 111 and the bottom surface of the first air intake area 112, thereby preventing the high-temperature sparks from entering the primary dust removal chamber 1 and avoiding the sparks from affecting the normal use of the filter cartridge 12.

[0043] Furthermore, refer to Figure 4 As shown, the side of the air inlet duct 11 is also provided with an inclined surface, and the end of the inclined surface is the primary dust removal chamber 1. The function of the inclined surface is that after the sparks are intercepted, they are in the form of granular spark debris, which can fall along the airflow along the inclined surface to the dust collection chamber 4 for collection, so as to avoid accumulating in the air inlet duct 11.

[0044] In some embodiments, reference Figure 4 and Figure 5 As shown, the dust collection chamber 4 includes a dust collection hopper 41, a suction pipe 42, an interception opening and closing structure 43, and an air supply valve 44. The dust collection hopper 41 is divided into two sections in the vertical direction, namely the first dust collection section 411 and the second dust collection section 412. The first dust collection section 411 and the second dust collection section 412 are separated by the interception opening and closing structure 43. The first dust collection section 411 provides a place for the accumulation of dust or ash. When the accumulation reaches a certain level, the interception opening and closing structure 43 is opened, so that the accumulated dust or ash falls into the second dust collection section 412.

[0045] The suction pipe 42 is located in the second dust collection section 412, and one end is connected to a suction device, such as an exhaust fan, which can draw dust out of the second dust collection section 412 along the suction pipe 42. The other end is equipped with an air supply valve 44. The function of the air supply valve 44 is that when the interception opening and closing structure 43 is closed, the air supply valve 44 can be opened to allow air to enter the suction pipe 42 from the other end, forming a negative pressure to ensure the stable discharge of dust or powder.

[0046] Specifically, the first dust collection section 411 and the second dust collection section 412 are separated by the interception and opening structure 43. When the dust or dust accumulated in the first dust collection section 411 reaches a certain amount, the interception and opening structure 43 is opened, allowing the dust or dust to fall uniformly into the second dust collection section 412. At this time, the interception and opening structure 43 separates the first dust collection section 411 and the second dust collection section 412, allowing the filter cartridge 12 above the first dust collection section 411 to continue filtering, while the dust or dust in the second dust collection section 412 can be discharged through the suction pipe 42 by using an external dust collection device and opening the air supply valve 44. At the same time, through the separation effect of the interception and opening structure 43, the dust discharge of the second dust collection section 412 and the dust collection of the first dust collection section 411 can be carried out simultaneously.

[0047] Further reference Figure 5 As shown, the interception opening and closing structure 43 includes a first opening and closing fan 431, a second opening and closing fan 432, an opening and closing bearing 433, a linkage shaft 434, a first linkage frame 435, a second linkage frame 436, and an opening and closing handle 437. There are four sets of opening and closing bearings 433, which are installed in pairs opposite to each other on the inner wall of the first dust collection section 411, that is, on both sides of the first dust collection section 411. Two sets of opening and closing bearings 433 are provided on each side, and the positions of the opening and closing bearings 433 on both sides are opposite to each other.

[0048] Both the first and second opening / closing fans 431 and 432 are equipped with a linkage shaft 434, which is pivotally connected to the opening / closing bearing 433. The first and second opening / closing fans 431 and 432 can rotate along the opening / closing bearing 433 following the linkage shaft 434. When the first and second opening / closing fans 431 and 432 rotate and are parallel to each other at the same height, they form a straight line, thus blocking dust and preventing it from falling into the second dust collection section 412. Conversely, when the first and second opening / closing fans 431 and 432 are misaligned by the rotation of the linkage shaft 434, the dust or dirt on the first and second opening / closing fans 431 and 432 can fall into the second dust collection section 412.

[0049] Two sets of linkage shafts 434 on one side of the first dust collection section 411 extend outward from the corresponding bearing seats. A first linkage frame 435 is installed at one end of the two sets of linkage shafts 434 outside the first dust collection section 411. The first linkage frame 435 can rotate with the linkage shaft 434 and can also drive the linkage shaft 434 to rotate. A second linkage frame 436 is hinged between the two first linkage frames 435. An opening and closing handle 437 is provided on any linkage shaft 434 with a first linkage frame 435. When the user or worker turns the opening and closing handle 437, the corresponding linkage shaft 434 can be driven to rotate. At the same time, the second linkage frame 436 can drive the first linkage frame 435 of the other linkage shaft 434 to rotate, thereby synchronously driving the two sets of linkage shafts 434 to achieve the synchronous opening and closing effect of the first opening and closing fan 431 and the second opening and closing fan 432.

[0050] The rotation angle of the first opening fan 431 and the second opening fan 432 does not need to be too large. It only needs to rotate at any suitable angle between 30° and 90° so that the dust can fall along the inclined surface at that angle. Therefore, the first linkage frame 435 and the second linkage frame 436 do not need to drive the linkage shaft 434 to rotate too much.

[0051] Specifically, by rotating the opening and closing handle 437, the opening and closing handle 437 drives the corresponding linkage shaft 434 to rotate along the opening and closing bearing 433. Through the hinge action of the first linkage frame 435 and the second linkage frame 436, the other linkage shaft 434 is pushed to rotate, so that the first opening and closing fan 431 and the second opening and closing fan 432 rotate synchronously to realize the synchronous opening or closing of the first dust collection section 411, so that dust or dust can fall into the second dust collection section 412. When the dust or dust in the second dust collection section 412 begins to be discharged, the first opening and closing fan 431 and the second opening and closing fan 432 close, so that the first dust collection section 411 can continue to collect dust or dust, and the second dust collection section 412 discharges dust synchronously. The two can operate synchronously without interfering with each other.

[0052] The opening and closing handle 437 can be replaced with an opening and closing motor, which drives the linkage shaft 434 to rotate, providing a more automated opening and closing effect compared to using the opening and closing handle 437.

[0053] In some embodiments, reference Figure 1 As shown, the top of the primary dust removal chamber 1 is also equipped with a flameless venting device 13. The flameless venting device 13 is a safety device specially designed for indoor dust explosion protection. It mainly consists of an explosion-proof plate and a fire extinguishing module. The working principle is that the explosion-proof plate quickly responds to the explosion pressure and opens to release pressure. At the same time, the fire extinguishing module uses flame-arresting elements to cool the flame and retain the dust, eliminate deflagration flames and high-pressure gases, and prevent secondary explosions. This increases the safety factor in the primary dust removal chamber 1 and improves the overall safety of use.

[0054] Furthermore, a differential pressure sensor (not shown in the figure) is installed in the backflush chamber 2. The differential pressure sensor is used to detect the differential pressure in the backflush chamber 2. When the negative pressure fan 31 is at the same power, if the differential pressure in the backflush chamber 2 is much lower than the standard differential pressure, it indicates that the filter cartridge 12 is covered by dust or dirt and cannot achieve normal gas flow. At this time, the differential pressure sensor can transmit to the external controller, and the controller can issue a control command to open the pulse cleaning device 21. If the pulse cleaning device 21 is equipped with a control switch, it can also be directly opened according to the electrical signal sent by the differential pressure sensor to the control switch. The specific opening method depends on the requirements.

[0055] The differential pressure sensor constantly monitors the pressure difference changes in the backflush chamber 2. When the pressure difference is lower than the standard value, an electrical signal is sent to activate the pulse cleaning device 21, thereby automatically cleaning the dust or powder accumulated on the filter cartridge 12.

[0056] Furthermore, the inner wall of the fan room 3 is also lined with sound-absorbing cotton (not shown in the figure, covering the inner wall of the fan room 3). The sound-absorbing cotton can absorb the noise generated by the negative pressure fan 31 on the inner wall of the fan room 3, reducing the noise transmitted from the fan room 3. Although the fan room 3 itself has heat dissipation windows or ventilation windows, the use of sound-absorbing cotton to reduce the transmission of noise can still make the environment quieter and improve the comfort of the working environment.

[0057] Further, refer to Figure 2 As shown, several noise reduction panels 51 are arranged vertically inside the noise reduction chamber 5. At least two noise reduction panels 51 are provided, and rock wool baffles can be used. Staggered air vents 52 are provided between adjacent noise reduction panels 51, that is, the air vents 52 are staggered, so that the airflow flows in a Z-shaped path. In this way, when the gas carries the noise to the noise reduction panel 51, it directly contacts the noise reduction panel 51 to provide noise reduction. After the gas continues to flow, it enters another noise reduction panel 51 through the air vent 52 for further noise reduction. Finally, the gas flows from the air vent 52 on the other side, forming a Z-shaped path, thereby further reducing the noise and improving the comfort of the environment.

[0058] Furthermore, refer to Figure 2 As shown, the secondary dust removal chamber 6 is equipped with a high-efficiency filter element 61, also known as a high-efficiency filter, which can intercept the gas transported by the noise reduction chamber 5, so that dust or dust particles such as dust particles in the gas can be further intercepted more finely. It can effectively collect 0.1-0.3 micron particles. The overall structure can be made of materials such as glass fiber, chemical fiber or aluminum alloy frame.

[0059] In some embodiments, reference Figure 6 As shown, the backflushing chamber 2 is also equipped with a switching structure 7, a switching pipe group 8 and an air inlet pipe group 9. The switching pipe group 8 is connected to the pulse cleaning device 21, and the switching component is connected to the switching pipe group 8.

[0060] The air inlet duct group 9 consists of several air inlet ducts. One end of the air inlet duct group 9 is connected to the switching duct group 8, and the other end passes through the back-blowing chamber 2 to enter the secondary dust removal chamber 6 and is connected to the high-efficiency filter element 61.

[0061] The function of the switching structure 7 is to switch the back-blowing direction. That is, the pulse cleaning device 21 originally performs pulse cleaning on the filter cartridge 12 in the primary dust removal chamber 1. After switching, the object of the pulse cleaning device 21 is changed to the high-efficiency filter element 61.

[0062] By using the switching assembly to connect the air inlet pipe group 9 to the switching pipe group 8, when the pulse cleaning device 21 sends out compressed air, it enters the air inlet pipe group 9 through the switching pipe group 8, so that the compressed air enters the high-efficiency filter element 61 through the air inlet pipe group 9 to back-blow the high-efficiency filter element 61. The high-efficiency filter element 61 is also connected to the external environment to back-blow and clean the dust on the high-efficiency filter element 61.

[0063] When the switching pipe assembly 8 is not connected to the air inlet pipe assembly 9, the switching pipe assembly 8 is directly connected to the back-blowing chamber 2, so that the back-blowing effect directly affects the filter cartridge 12 in the primary dust removal chamber 1, that is, it provides back-blowing to the filter cartridge 12. Through the switching action of the switching component, the back-blowing direction can be switched according to the needs.

[0064] Further reference Figure 7 and Figure 8 As shown, the switching structure 7 includes a switching box 71, a drive cylinder 72, a switching seat 73, a push cylinder 74, an inclined rail 75, a docking block 76, a first wedge block 77, and a second wedge block 78. The switching box 71 is fixed to the bottom surface of the backflush chamber 2. The switching pipe assembly 8 is connected to the top surface of the switching box 71. A backflush port 711 communicating with the backflush chamber 2 is opened on one side of the switching box 71. The air inlet pipe assembly 9 is connected to the wall of the switching box 71 on the other side of the backflush port 711 and communicates with the switching box 71. The switching seat 73 is installed inside the switching box 71. The switching seat 73 moves along the inner wall of the switching box 71. The switching seat 73 is L-shaped. When the switching seat 73 moves, it can block the back-blowing port 711. The switching seat 73 is provided with a baffle plate 731 on the side near the air inlet pipe group 9. The baffle plate 731 is offset from the switching seat 73. When the switching seat 73 moves along the switching box 71 to block the back-blowing port 711, the air inlet pipe group 9 is connected to the switching box 71. When the switching seat 73 moves along the switching box 71 to open the back-blowing port 711, the baffle plate 731 blocks the air inlet pipe group 9, so that the pipe opening of the air inlet pipe group 9 is blocked and closed.

[0065] The drive cylinder 72 is installed inside the switching box 71, and the drive end is connected to the switching seat 73 to drive the switching seat 73 to move along the inner wall of the switching box 71, thereby realizing the opening and closing of the back-blowing port 711 and the air inlet pipe group 9.

[0066] The drive cylinder 72 can be a regular cylinder or a magnetically coupled rodless cylinder, preferably a magnetically coupled rodless cylinder, which can reduce the required installation length of the switching box 71. Located inside the switching box 71, it can provide a certain degree of protection.

[0067] A push cylinder 74 is installed on a switching seat 73, and a first wedge block 77 is provided at the drive end. An inclined rail 75 is installed on the switching seat 73. A docking block 76 is slidably connected to the inclined rail 75. The inclined rail 75 serves as the load-bearing structure of the docking block 76. A second wedge block 78 is provided at the bottom of the docking block 76. The first wedge block 77 and the second wedge block 78 abut against each other. When the push cylinder 74 drives the first wedge block 77 to move, it pushes the second wedge block 78 to move along the inclined direction, so that the docking block 76 can move along the inclined rail 75.

[0068] The docking block 76 has an L-shaped air delivery channel 761. When the docking block 76 is pushed by the push cylinder 74 and moves along the inclined rail 75, one end of the air delivery channel 761 abuts against the switching pipe group 8 and the other end abuts against the air receiving pipe group 9, thereby docking the switching pipe group 8 and the air receiving pipe group 9 to realize the switching of the compressed air delivery direction.

[0069] Specifically, when the pulse cleaning device 21 needs to backflush the primary dust collection chamber 1, the drive cylinder 72 drives the switching seat 73 to move along the switching box 71 and opens the backflushing port 711. At the same time, the baffle plate 731 blocks the air inlet duct assembly 9, allowing the compressed air emitted by the pulse cleaning device 21 to enter the primary dust collection chamber 1 through the backflushing port 711. When the high-efficiency filter element 61 needs to be backflushed for dust removal, the drive cylinder 72 drives the switching seat 73 to move, blocking the backflushing port 711, and the baffle plate... 731 Open the air inlet pipe assembly 9, and then push the cylinder 74 to drive the first wedge block 77 to move towards the inclined rail 75. The first wedge block 77 pushes the second wedge block 78 to move the docking block 76 along the inclined rail 75 until the two air supply channels 761 are respectively connected to the switching pipe assembly 8 and the air inlet pipe assembly 9. The compressed air generated by the pulse dust removal device 21 can be delivered to the air inlet pipe assembly 9 through the air supply channel 761 to back-flush the high-efficiency filter element 61 in the secondary dust removal chamber 6 for dust removal.

[0070] Furthermore, to enhance sealing, a sealing ring is provided at one end of the switching pipe assembly 8 and the air inlet pipe assembly 9 located inside the switching box 71. A sealing ring is also provided at the air supply channel 761 opening of the connecting block 76. When the air supply channel 761 connects with the switching pipe assembly 8 and the air inlet pipe assembly 9, the sealing rings of the two are fitted together to improve the sealing effect and reduce the loss of compressed air.

[0071] Furthermore, refer to Figure 3 and Figure 6 As shown, a recycling drawer 53 is provided at the air vent 52 near the secondary dust removal chamber 6 in the noise reduction chamber 5. The recycling drawer 53 is embedded in the wall of the noise reduction chamber 5. When compressed air is delivered to the high-efficiency filter element through the air duct, the dust attached to the high-efficiency filter element 61 in the secondary dust removal chamber 6 will also fall off due to the impact of the compressed air. Therefore, part of the compressed air is discharged from the secondary dust removal chamber 6, and part of the compressed air is discharged from the air vent 52 and falls into the recycling drawer 53. Workers or users can take out the recycling drawer 53 from outside the dust collector to collect the fallen dust.

[0072] The recycling drawer 53 does not block the vent 52; it is simply located below the vent 52.

[0073] If the recycling drawer 53 is not installed, dust or particulate matter will flow in the opposite direction into the primary dust removal chamber 1 and may also fall into the dust collection chamber 4. However, installing the recycling drawer 53 can improve the dust recycling effect.

[0074] Noise-reducing panels can also be installed inside the recycling drawer 53.

[0075] An electrostatic plate (not shown in the figure, located below the noise reduction plate) can be installed inside the recycling drawer 53. When energized, it generates static electricity, causing dust or particulate matter detached from the high-efficiency filter element 61 in the secondary dust removal chamber 6 to flow with the gas to the recycling drawer 53, where it is attracted by the electrostatic force. The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
