Description

Technical Field

[0001] This invention relates to the field of baghouse dust collection technology, and in particular to a baghouse dust collection and cleaning system. Background Technology

[0002] Baghouse dust collectors are a common type of equipment in the current dust removal field. They filter dust-laden gas using filter bags (or other filter materials), trapping dust particles on the surface of the bags to achieve air purification.

[0003] Regarding the aforementioned technologies, in traditional bag cleaning processes, air is typically injected into the bag and the bag is shaken, with the dust then being removed by gravity. However, due to the negative pressure at the bag opening, dust is drawn back in and adheres to the outer surface of the bag, reducing the cleaning quality and impacting the efficiency of bag dust removal. Summary of the Invention

[0004] The purpose of this application is to provide a bag filter dust removal system to solve the problem that when the bag filter is restarted after cleaning, the dust that has been shaken off will be re-adsorbed onto the bag filter.

[0005] The dust collection and cleaning system provided in this application adopts the following technical solution: it includes four bottom boxes, a dust collection component, a locking component, and four air outlets. The dust collection component includes a dust collection box body that is fixedly connected to the top of the four bottom boxes. Two support blocks are fixedly connected to both sides of the inner wall of the dust collection box body. A support plate is attached to the top of the four support blocks. Screws are threadedly connected to the support blocks and the support plates. Several dust collection bags are arranged inside the support plates. One end of each of the four air outlets is fixedly connected to a bend pipe. A tapered pipe is fixedly connected to the bottom end of the bend pipe. Each of the four dust collection boxes has a top box fixedly connected to its top. Each of the four top boxes has an air outlet on its side. The leftmost air outlet has an air outlet pipe A fixedly installed at one end via a flange. The rightmost air outlet has an air outlet pipe D fixedly installed at one end via a flange. The middle left air outlet has an air outlet pipe B fixedly installed at one end via a flange. The middle right air outlet has an air outlet pipe C fixedly installed at one end via a flange. The bottom surfaces of air outlet pipes A, B, C, and D are provided with upper pipes. A vacuum pump is fixedly installed on the side of one of the dust collection boxes. The vacuum pump has a conveying pipe and an exhaust pipe fixedly connected inside. One end of the conveying pipe is connected to one end of the upper pipe via a flange. Each of the four base boxes has an air inlet on its side. The leftmost air inlet is fixedly fitted with an air inlet pipe A via a flange, the rightmost air inlet is fixedly fitted with an air inlet pipe D via a flange, the middle left air inlet is fixedly fitted with an air inlet pipe B via a flange, and the middle right air inlet is fixedly fitted with an air inlet pipe C via a flange. The top surfaces of air inlet pipes A, B, C, and D are provided with lower pipes. One end of the lower pipe is connected to a conical cover. The inner wall surface of the lower pipe has several recessed holes. Several stainless steel elastic sheets are fixedly connected to the side of the conical cover. The surface of the stainless steel elastic sheets is fixedly connected with convex balls, which are engaged inside the recessed holes. Three solenoid valves are fixedly installed on the surface of the upper pipe. The three solenoid valves are used to control the opening and closing of air outlet pipe A, air outlet pipe B and air outlet pipe C respectively. By adopting the above technical solution, and by setting up multiple independent dust collection chambers, multiple solenoid valves, upper pipes, outlet pipes A, B, C, and D, lower pipes, inlet pipes A, B, C, and D, and a vacuum pump, the vacuum pump can start during normal dust collection. At this time, all solenoid valves in the upper pipe are in the open state, and then negative pressure is generated at the outlets of the four dust collection chambers. Subsequently, the dust-laden gas will enter the lower pipe from the conical hood, and then enter the corresponding inlet and bottom through inlet pipes A, B, C, and D. Inside the chamber, dust is trapped by the filter bags. The purified gas then flows through conical pipes, bends, and outlets into outlet pipes A, B, C, and D. It then merges into the upper duct and is finally discharged through the exhaust pipe. When cleaning the filter bags in outlet pipe A, the solenoid valve corresponding to outlet pipe A is closed, cutting off the negative pressure source for that dust collector chamber. At this point, there is no negative pressure difference inside or outside the filter bags. Meanwhile, the solenoid valves in outlet pipes B and C remain open, and outlet pipe D is also unobstructed. In the open state, the corresponding dust collector chamber remains under negative pressure. All the inlet pipes A, B, C, and D of the bottom chambers are interconnected via a lower pipe, forming a cross-zone flow channel. Subsequently, dust in the bottom chamber of the dust collector at outlet pipe A is drawn into the lower pipe through outlet pipe A under the negative pressure of outlet pipes B, C, and D, and then sucked into the dust collector chambers corresponding to the still-operating outlet pipes B, C, and D. The dust is then further filtered by the filter bags within these dust collector chambers. Afterwards, the dust from outlet pipe A... After the corresponding dust collector bags are cleaned, the solenoid valves corresponding to the outlet pipes C and D are closed in sequence. The above cleaning and diversion steps are repeated. Finally, when all the dust is absorbed into the dust collector box at the outlet pipe D, the dust in the bottom box is cleaned in a unified manner. This achieves the goal of cutting off the negative pressure of the target dust collector box during cleaning, thus preventing the shaken dust from being re-absorbed by the negative pressure at the dust collector bag opening. At the same time, the negative pressure of other dust collector boxes can be used for cross-zone diversion, realizing the effect of immediate transfer and collection of cleaning dust, and preventing dust from accumulating in the bottom box. By setting up support blocks, support plates, and screws, the screws can be turned and the support plate removed, allowing for external maintenance of the dust collector bag. This facilitates the maintenance and replacement of the dust collector bag. By setting up recessed holes, stainless steel elastic sheets, and convex balls, workers can press the stainless steel elastic sheets, and then the convex balls and stainless steel elastic sheets will enter the lower pipe. When moved to the recessed holes, the convex balls can easily lock into the recessed holes, thereby locking the conical cover and achieving the purpose of convenient disassembly and assembly of the conical cover.

[0006] Preferably, a plurality of support legs are fixedly connected to the bottom of the four base boxes, and a base plate is fixedly connected to the bottom of the support legs; By adopting the above technical solution and setting up support legs and a base plate, the stability of the entire bag filter dust removal system can be enhanced, making it less prone to shaking or tipping over due to external forces during operation.

[0007] Preferably, sealing plates are fixedly installed on the sides of all four dust collection boxes using studs; By adopting the above technical solution and setting a sealing plate, when it is necessary to inspect the inside of the dust collector, the sealing plate can be easily removed, thereby allowing access to the inside of the dust collector for operation.

[0008] Preferably, each of the four bottom boxes has a door movably connected to its side via a hinge, and a handle is fixedly connected to the side of each door. By adopting the above technical solution and setting up a box door and handle, staff can easily open the box door and then clean the small amount of dust or the collected dust inside the bottom box.

[0009] Preferably, a viewing window is provided on the side of the cabinet door; By adopting the above technical solution and setting up a viewing window, staff can directly observe the accumulation of dust inside the box without opening the box door, thus arranging cleaning work in a timely manner.

[0010] Preferably, the locking assembly includes a horizontal block fixedly connected to the side of the box door, three support rods fixedly connected to the side of the horizontal block, a vertical block fixedly connected to the side of the bottom box, a limiting groove, a sliding groove and two recesses opened inside the vertical block, the support rods being located inside the limiting groove, a locking plate being inserted into the sliding groove, a spring fixedly connected to the top of the recess, the bottom surface of the spring being fixedly connected to the top of the locking plate, a through groove opened on the side of the vertical block, and a lifting block fixedly connected to the side of the locking plate, the lifting block being movable inside the through groove; By adopting the above technical solution and setting a locking component, when the cabinet door needs to be closed, the operator can pull the lifting block, which will compress the spring. Then the lifting block can move in the through groove and drive the locking plate to move in the slide groove. At this time, the support rod can be pushed into the limiting groove. When the cabinet door is closed in place, the lifting block is released, and the locking plate is reset under the elastic force of the spring, thereby restricting the support rod in the limiting groove and achieving the purpose of locking the cabinet door.

[0011] Preferably, the bottom of the tapered tube and the top of the support plate are both fixedly connected with sealing rings, and the two sealing rings are interlocked. By adopting the above technical solution and setting a sealing ring, when the tapered tube is connected to the support plate, the two sealing rings can be interlocked, which can enhance the sealing performance of the connection between the tapered tube and the support plate and prevent dust or other impurities from leaking out from the connection.

[0012] Preferably, the surface of the lifting block is provided with anti-slip texture; By adopting the above technical solution and setting anti-slip texture, the friction between the worker's fingers and the lifting block can be increased, preventing the hand from slipping when pulling the lifting block. Beneficial effects

[0013] In summary, this application includes at least one of the following beneficial technical effects: This invention provides a baghouse dust collector cleaning system. By configuring multiple independent dust collector housings, multiple solenoid valves, an upper pipe, outlet pipes A, B, C, and D, a lower pipe, inlet pipes A, B, C, and D, and a vacuum pump, the system can operate normally. When the vacuum pump starts, all solenoid valves in the upper pipe are open, creating negative pressure at the outlets of all four dust collector housings. The dust-laden gas then enters the lower pipe through the conical hood, and subsequently flows through inlet pipes A, B, C, and D into the corresponding outlets. Inside the air inlet and bottom chamber, dust is trapped by the filter bags. The purified gas then passes through the conical pipe, bend, and outlet into outlet pipes A, B, C, and D, before converging into the upper duct and finally being discharged through the exhaust pipe. When cleaning the filter bags in outlet pipe A, the solenoid valve corresponding to outlet pipe A is closed, cutting off the negative pressure source for that dust collector chamber. At this point, there is no negative pressure difference inside or outside the filter bags in the dust collector chamber. Meanwhile, the solenoid valves of outlet pipes B and C remain open, and the air inside outlet pipe D... This is also a smooth flow condition, meaning the corresponding dust collector chamber remains under negative pressure. All the inlet pipes A, B, C, and D of the bottom chambers are interconnected via a lower pipe, forming a cross-zone flow channel. Subsequently, dust in the bottom chamber of the dust collector at outlet pipe A will be drawn into the lower pipe via outlet pipe A under the negative pressure of outlet pipes B, C, and D, and then sucked into the dust collector chambers corresponding to the still-operating outlet pipes B, C, and D. The dust will then be further filtered by the filter bags within these dust collector chambers. Afterwards, the dust will be discharged from the outlet pipe... After the dust collector bag corresponding to A is cleaned, the solenoid valves corresponding to the outlet pipes C and D are closed in sequence. The above cleaning and diversion steps are repeated. Finally, when all the dust is absorbed into the dust collector box at the outlet pipe D, the dust in the bottom box is cleaned in a unified manner. This achieves the goal of cutting off the negative pressure of the target dust collector box during cleaning, thus preventing the shaken dust from being re-absorbed by the negative pressure at the dust collector bag opening. At the same time, the negative pressure of the other dust collector boxes can be used for cross-zone diversion, realizing the effect of immediate transfer and collection of cleaning dust, and preventing dust from accumulating in the bottom box.

[0014] This invention provides a bag filter dust removal system. By setting up a support block, a support plate, and screws, the support plate can be removed by turning the screws, allowing for external maintenance of the dust collector bag. This facilitates the maintenance and replacement of the dust collector bag. By setting up a concave hole, a stainless steel elastic sheet, and a convex ball, the operator can press the stainless steel elastic sheet, and then the convex ball and stainless steel elastic sheet will enter the lower pipe. When it moves to the concave hole, the convex ball can easily lock into the concave hole, thereby locking the conical cover, achieving the purpose of convenient disassembly and assembly of the conical cover.

Detailed Implementation

[0017] The following is in conjunction with the appendix Figure 1-Appendix Figure 7 This application will be described in further detail below.

[0018] Example 1: A bag filter dust removal system, referring to Figure 1 , Figure 3 , Figure 4 and Figure 7 It includes four base boxes 1, a dust removal assembly 2, a locking assembly 20, and four air outlets 27. The dust removal assembly 2 includes a dust removal box body 201 that is fixedly connected to the top of the four base boxes 1. Two support blocks 202 are fixedly connected to both sides of the inner wall of the dust removal box body 201. A support plate 203 is attached to the top of the four support blocks 202. Screws 204 are threadedly connected to the support blocks 202 and the support plate 203. Several dust removal bags 205 are provided inside the support plate 203. One end of each of the four air outlets 27 is fixedly connected to a bend pipe 206. A tapered pipe 207 is fixedly connected to the bottom end of the bend pipe 206. The top of each of the four dust collection boxes 201 is fixedly connected to a top box 3. Each of the four top boxes 3 is provided with an air outlet 27 on its side. One end of the leftmost air outlet 27 is fixedly installed with an air outlet pipe A10 via a flange. One end of the rightmost air outlet 27 is fixedly installed with an air outlet pipe D13 via a flange. One end of the middle left air outlet 27 is fixedly installed with an air outlet pipe B11 via a flange. One end of the middle right air outlet 27 is fixedly installed with an air outlet pipe C12 via a flange. The bottom surfaces of the air outlet pipes A10, B11, C12 and D13 are provided with an upper pipe 14. A vacuum pump 15 is fixedly installed on the side of one of the dust collection boxes 201. The vacuum pump 15 is fixedly connected to a conveying pipe 16 and an exhaust pipe 17. One end of the conveying pipe 16 is connected to one end of the upper pipe 14 via a flange. Each of the four base boxes 1 has an air inlet 26 on its side. The leftmost air inlet 26 has an air inlet pipe A4 fixedly installed at one end via a flange. The rightmost air inlet 26 has an air inlet pipe D7 fixedly installed at one end via a flange. The middle left air inlet 26 has an air inlet pipe B5 fixedly installed at one end via a flange. The middle right air inlet 26 has an air inlet pipe C6 fixedly installed at one end via a flange. The top surfaces of the air inlets A4, B5, C6 and D7 are provided with a lower pipe 8. One end of the lower pipe 8 is connected to a conical cover 24. The inner wall surface of the lower pipe 8 is provided with several recesses 30. Several stainless steel elastic sheets 31 are fixedly connected to the side of the conical cover 24. The surface of the stainless steel elastic sheets 31 is fixedly connected with a convex ball 32, which is engaged inside the recesses 30. Three solenoid valves 9 are fixedly installed on the surface of the upper pipe 14. These three solenoid valves 9 are used to control the opening and closing of the outlet pipes A10, B11, and C12, respectively. By setting up multiple independent dust collection chambers 201, multiple solenoid valves 9, the upper pipe 14, outlet pipes A10, B11, C12, and D13, the lower pipe 8, inlet pipes A4, B5, C6, and D7, and a vacuum pump 15, the system can operate normally during dust collection. When the vacuum pump 15 starts, all the solenoid valves 9 in the upper pipe 14 are open. Then, negative pressure is generated at the outlets 27 of the four dust collection chambers 201. Subsequently, the dust-laden gas enters the lower pipe 8 from the conical hood 24, and then... Inlet pipes A4, B5, C6, and D7 enter their respective inlets 26 and the bottom chamber 1. Dust is subsequently trapped by the filter bags 205. The purified gas then passes through the conical pipe 207, the bend 206, and the outlet 27 into the corresponding outlet pipes A10, B11, C12, and D13, and then flows into the upper pipe 14, finally being discharged through the exhaust pipe 17. When cleaning the filter bags 205 corresponding to outlet pipe A10, the solenoid valve 9 corresponding to outlet pipe A10 is closed, thus cutting off the negative pressure source of the dust collector 201. At this time, there is no negative pressure difference inside and outside the filter bags 205 of the dust collector 201. Then, due to the remaining outlet pipes... Solenoid valves 9 of B11 and C12 remain open, and the interior of D13 is also unobstructed. Consequently, the corresponding dust collector 201 remains under negative pressure. All inlet pipes A4, B5, C6, and D7 of the bottom chamber 1 are interconnected via the lower pipe 8, forming a cross-zone flow channel. Subsequently, dust within the bottom chamber 1 of the dust collector 201 at outlet pipe A10 is drawn by the negative pressure of outlet pipes B11, C12, and D13 into the lower pipe 8 via inlet pipe A4, and then sucked into the still-operating dust collectors 201 corresponding to outlet pipes B11, C12, and D13. This dust is then further drawn into these dust collectors 201. The dust collector bag 205 inside completes secondary interception. After the dust collector bag 205 corresponding to the air outlet duct A10 is cleaned, the solenoid valves 9 corresponding to the air outlet duct C12 and air outlet duct D13 are closed in sequence. The above dust cleaning and diversion steps are repeated. Finally, when all the dust is absorbed into the dust collector box 201 at the air outlet duct D13, the dust in the bottom box 1 is cleaned in a unified manner. This achieves the goal of cutting off the negative pressure of the target dust collector box 201 during dust cleaning, and avoids the purpose of re-absorbing the shaken dust by the negative pressure at the dust collector bag 205 opening from the root. At the same time, the negative pressure of the other dust collector boxes 201 can be used for cross-zone diversion, realizing the effect of immediate transfer and collection of dust during dust cleaning, and avoiding the accumulation of dust in the bottom box 1. By setting up support block 202, support plate 203 and screw 204, the screw 204 can be turned and the support plate 203 can be removed, and the dust collector bag 205 can be maintained externally. This achieves the purpose of facilitating the maintenance and replacement of the dust collector bag 205. By setting up concave hole 30, stainless steel elastic sheet 31 and convex ball 32, the operator can press the stainless steel elastic sheet 31, and then the convex ball 32 and stainless steel elastic sheet 31 will enter the lower pipe 8. When it moves to the concave hole 30, the convex ball 32 can be easily inserted into the concave hole 30, thereby locking the conical cover 24, achieving the purpose of convenient disassembly and assembly of the conical cover 24.

[0019] Please see Figure 1 and Figure 2 Several support legs 18 are fixedly connected to the bottom of the four base boxes 1, and a base plate 19 is fixedly connected to the bottom of the support legs 18. By setting the support legs 18 and the base plate 19, the stability of the entire bag filter dust removal system can be enhanced, making it less likely to shake or tip over due to external forces during operation. The sides of the four dust collector boxes 201 are all fixedly installed with sealing plates 25 by studs. By setting the sealing plates 25, when it is necessary to inspect the inside of the dust collector box 201, the sealing plates 25 can be easily removed to enter the dust collector box 201 for operation.

[0020] Please see Figure 2 Each of the four bottom boxes 1 has a door 21 connected to its side by hinges. A handle 22 is fixedly connected to the side of each door 21. By setting the door 21 and the handle 22, the staff can easily open the door 21 to clean the small amount of dust or the concentrated dust inside the bottom box 1. The side of the door 21 is provided with a viewing window 23. By setting the viewing window 23, the staff can directly observe the dust accumulation inside the bottom box 1 without opening the door 21, so as to arrange the cleaning work in a timely manner.

[0021] Please see Figure 4 , Figure 5 and Figure 6The locking assembly 20 includes a horizontal block 2001 fixedly connected to the side of the door 21. Three support rods 2002 are fixedly connected to the side of the horizontal block 2001. A vertical block 2003 is fixedly connected to the side of the bottom box 1. The vertical block 2003 has a limiting groove 2004, a sliding groove 2005, and two recesses 2009 inside. The support rods 2002 are located inside the limiting groove 2004. A locking plate 2006 is inserted into the sliding groove 2005. A spring is fixedly connected to the top of the recess 2009. Spring 2010 is fixedly connected to the top of lock plate 2006 at its bottom surface. A through groove 2008 is provided on the side of vertical block 2003. A lifting block 2007 is fixedly connected to the side of lock plate 2006. The lifting block 2007 is movable inside the through groove 2008. By setting the locking component 20, when the door 21 needs to be closed, the operator can pull the lifting block 2007, thereby compressing spring 2010. Then, the lifting block 2007 can move within the through groove 2008. The locking plate 2006 moves within the slide groove 2005, allowing the support rod 2002 to be pushed into the limiting groove 2004. Once the door 21 is closed, the lifting block 2007 is released, and the locking plate 2006 resets under the force of the spring 2010, thus confining the support rod 2002 within the limiting groove 2004, achieving the purpose of locking the door 21. Both the bottom of the tapered tube 207 and the top of the support plate 203 are fixedly connected to sealing rings 28, with the two sealing rings 28 interlocking. The tapered tube 207 is connected to the support plate 203 by a snap-fit ​​mechanism. The two sealing rings 28 snap together to enhance the sealing of the connection between the tapered tube 207 and the support plate 203, preventing dust or other impurities from leaking out. The surface of the lifting block 2007 is provided with anti-slip texture 29. By providing anti-slip texture 29, the friction between the operator's fingers and the lifting block 2007 can be increased, preventing the hand from slipping when pulling the lifting block 2007.

[0022] The implementation principle of this application embodiment is as follows: First, when it is necessary to clean the dust in the gas, the vacuum pump 15 is started. Then, the vacuum pump 15 generates negative pressure on the upper pipe 14 through the delivery pipe 16. At this time, the three solenoid valves 9 on the upper pipe 14 that control the air outlet pipe A10, air outlet pipe B11, and air outlet pipe C12 are all in the open state, and the air outlet pipe D13 remains open. Subsequently, the four dust collection boxes 201 all form a negative pressure environment. Then, the dust-laden gas enters the lower pipe 8 through the conical hood 24, and then flows into the air inlets of the four bottom boxes 1 through the air inlet pipes A4, B5, C6, and D7 respectively. 26. The dust then enters the corresponding dust collection box 201. Under negative pressure, the dust is trapped by the dust collection bag 205 on the support plate 203. During the trapping process, the sealing ring 28 at the connection between the conical tube 207 and the support plate 203 prevents the dust from leaking out of the gap. Then, the purified gas passes through the dust collection bag 205 and enters the air outlet 27 of the top box 3 of each dust collection box 201 through the conical tube 207 and the bent tube 206. Then, it flows into the upper pipe 14 through the air outlet pipe A10, air outlet pipe B11, air outlet pipe C12 and air outlet pipe D13, and is finally discharged through the exhaust pipe 17 of the vacuum pump 15. Subsequently, if it is necessary to clean the dust collector bag 205 corresponding to the outlet duct A10, the solenoid valve 9 corresponding to the outlet duct A10 can be closed, thereby cutting off the negative pressure source of the dust collector box 201. Then, there is no negative pressure difference inside and outside the dust collector bag 205, and the shaken dust falls into the corresponding bottom box 1. At this time, the solenoid valves 9 corresponding to the outlet ducts B11 and C12 remain open, while the outlet duct D13 remains open. At this time, the other three dust collector boxes 201 continuously generate negative pressure. Because each inlet duct is interconnected through the lower pipe 8 to form a cross-zone guiding channel, the dust in the bottom box 1 corresponding to the outlet duct A10 will be drawn into the lower pipe 8 through the inlet duct A4 under the negative pressure, and then sucked into the three dust collector boxes 201 that are still working, where it will be intercepted again by other dust collector bags 205. After the filter bags corresponding to exhaust duct A10 are cleaned, the solenoid valves 9 corresponding to exhaust ducts B11 and C12 are closed in sequence. The above-mentioned cleaning steps of cutting off negative pressure, cross-zone diversion, and secondary interception are repeated. After all the dust collector bags 205 are cleaned, the dust will be concentrated in the bottom box 1 corresponding to exhaust duct D13. Then, the staff can observe the dust accumulation through the viewing window 23. When there is too much dust, pull the lifting block 2007, which will compress the spring 2010. Then the lifting block 2007 can move in the through groove 2008 and drive the locking plate 2006 to move in the slide groove 2005. After the support rod 2002 is freed from the restraint of the locking plate 2006, the staff can hold the handle 22 to open the box door 21. Then, the dust in the bottom box 1 can be cleaned uniformly.
