Description

Technical Field

[0001] This invention relates to the technical field of dust collectors, specifically a dust removal type bag filter. Background Technology

[0002] Baghouse dust collectors are widely used in various construction sites as a highly efficient air filtration device. The dust collection bags inside are made of woven filter cloth or non-woven felt, and the dust-laden gas is filtered by the filtration effect of the fibrous fabric.

[0003] Existing box-type baghouse dust collectors typically consist of a box body and a filter and collection structure housed within it. The box body has inlet and outlet pipes for air intake and exhaust. The filter structure includes a mounting frame and filter bags mounted on the frame. The collection structure is a dust hopper located below the filter structure. The filter bags filter and trap dust from the air entering the box, collecting the trapped dust and impurities in the dust hopper. While this design is simple and easy to use, the following problems have been observed during operation:

[0004] 1. Air passes through the dust collector bag from one direction, while the dust collector bag remains stationary inside the housing. This results in a low overall utilization rate of the dust collector bag, a single form of contact between the air and the dust collector bag, and poor filtration and blocking effect.

[0005] 2. Dust collector bags tend to accumulate dust on their surface after prolonged use, requiring cleaning. A common method is to spray high-pressure gas into the dust collector bag to cause it to expand and contract, thus shaking off the dust. However, this method can lead to frequent stress on the fiber gaps of the dust collector bag, affecting its service life. Furthermore, cleaning requires pausing the filtration process and can easily generate dust inside the chamber, resulting in poor cleaning effectiveness.

[0006] Therefore, those skilled in the art have proposed a dust-removing bag filter to solve the problems mentioned in the background above. Summary of the Invention

[0007] The purpose of this invention is to provide a dust removal type bag filter to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A dust collector for cleaning type includes a housing, an air inlet pipe installed on the side of the housing, a dust collection hopper installed at the bottom of the housing, a working chamber located at the bottom of the inner cavity of the housing, a first drive motor installed in the center of the top surface of the working chamber, a sleeve rotatably connected to the center of the top of the working chamber via a first fixing frame, the bottom end of the sleeve being connected to the output end of the first drive motor, a dust collector bag fitted on the sleeve, a top plate detachably installed on the top of the housing, an air outlet pipe installed in the center of the top plate, and a second drive motor installed on the side of the top surface of the working chamber, connected to the side of the top of the working chamber via a second fixing frame. A cleaning component is rotatably connected, with its bottom end connected to the output end of the second drive motor. One end of the air inlet pipe extends into the housing and is connected to a diffuser pipe. A guide frame is provided on the side of the housing cavity corresponding to the diffuser pipe. One end of the guide frame is connected to the inner wall of the housing via a connecting component, and the other end of the guide frame is attached to the outer wall of the dust collector bag. The diffuser pipe is interlocked with the middle of the guide frame. One end of the air outlet pipe extends into the housing and is connected to a gathering cover. The bottom end of the gathering cover covers the top of the dust collector bag. The air inlet pipe and the cleaning component are located on different sides of the housing.

[0010] The frame includes a main frame rod, several vertical rods evenly distributed around the main frame rod via crossbars, and two collars. The two collars are respectively connected to the top and bottom of the vertical rods. A clamping assembly is connected to the end of each vertical rod near the main frame rod. The lower part of the main frame rod is rotatably connected to the first fixed frame, and the bottom of the main frame rod is connected to the output end of the first drive motor.

[0011] As a further embodiment of the present invention: the clamping assembly includes a connecting rod connected to the vertical rod, a threaded sleeve connected to the end of the connecting rod, and a threaded rod threadedly connected to the threaded sleeve. A pressure block is connected to one end of the threaded rod near the collar, and a throttle is connected to the other end of the threaded rod.

[0012] As a further embodiment of the present invention: the threaded rod and the threaded sleeve are inclined about the vertical rod, and the inner sidewall of the collar is provided with an adapter groove at the position corresponding to the threaded rod.

[0013] As a further embodiment of the present invention: the top of the guide frame is provided with an arc-shaped groove that matches the shape and size of the collar on the side near the sleeve, the bottom of the guide frame is provided with an opening, and the end of the guide frame away from the sleeve is provided with a circular hole with an inner diameter that matches the outer diameter of the diffuser tube.

[0014] As a further embodiment of the present invention: the connecting assembly includes a straight rod, a connecting sleeve, and a right-angle rod. The straight rod is inserted and connected to the side wall of the housing. One end of the straight rod is connected to the end of the guide frame away from the sleeve. A first elastic element is sleeved on the straight rod. The two ends of the end elastic element are respectively connected to the outer side wall of the guide frame and the inner side wall of the housing. The connecting sleeve is connected to the other end of the straight rod. One end of the right-angle rod is rotatably connected to the connecting sleeve, and the other end of the right-angle rod is connected to a stop plate.

[0015] As a further embodiment of the present invention: the cleaning assembly includes a first rotating rod and a first cleaning roller mounted on the upper part of the first rotating rod, the lower part of the first rotating rod is rotatably connected to a second fixed frame, and the bottom end of the first rotating rod is connected to the output end of a second drive motor.

[0016] As a further embodiment of the present invention, it also includes a tapping assembly disposed next to the cleaning assembly. The tapping assembly includes a second rotating rod, a side rod connected to the side wall of the second rotating rod, and a second cleaning roller mounted on the side rod. A drive gear is connected to the first rotating rod, and the lower part of the second rotating rod is rotatably connected to the second fixed frame. A driven gear is mounted on the second rotating rod, and the drive gear meshes with the driven gear.

[0017] The present invention has the following advantages:

[0018] 1. The air intake pipe, diffuser pipe and guide frame work together to ensure that the air can make good contact with the side of the dust collector bag after entering the box. After being filtered, the air enters the inside of the dust collector bag and is then discharged from the box through the collection hood and the exhaust pipe, so that no dust is generated inside the box.

[0019] 2. The dust collector bag is fitted onto the frame and fixed. The frame is rotated by the first drive motor, which in turn drives the dust collector bag to rotate. This allows the air delivered from the inlet pipe to fully contact all parts of the dust collector bag, resulting in high utilization of the dust collector bag. It also avoids the dust-laden air impacting one side of the dust collector bag for a long time, which can easily damage the dust collector bag and improve its service life.

[0020] 3. The dust collector bag is equipped with a cleaning component on its side to clean the outer wall of the dust collector bag while it is rotating. This effectively prevents dust from adhering to the dust collector bag and will not damage the dust collector bag during cleaning. The cleaning and filtration of the dust collector bag can be carried out simultaneously, which is highly efficient and has a good automation effect. The guide frame and the cleaning component are set on different sides of the dust collector bag so that they do not affect each other.

[0021] 4. In terms of structure, the overall dust collector adopts a box-type structure design. The detachable top plate facilitates the installation and removal of the dust collector bags. The dust collection hopper is easy to install and remove. The box is equipped with multiple air inlet pipes and is easy to move and set up, resulting in better performance.

[0033] The technical solution of the present invention will be further described in detail below with reference to specific embodiments. Example 1

[0034] Please see Figure 1 , 23, 9, A dust removal type bag filter includes a housing 1, with support legs 2 connected to the bottom of the housing 1 for supporting and fixing it. An air inlet pipe 101 is installed on the side of the housing 1. A dust collection hopper 3 is detachably installed at the bottom of the housing 1, and a dust discharge valve 301 is installed at the bottom of the dust collection hopper 3. A working box 4 is installed at the bottom of the inner cavity of the housing 1 via a mounting rod 104. A first drive motor 403 is installed in the middle of the top surface of the working box 4. A sleeve 8 is rotatably connected to the top center of the working box 4 via a first fixing frame 401. The bottom end of the sleeve 8 is connected to the output end of the first drive motor 403. A dust collector bag 9 is fitted onto the frame 8. The size of the frame 8 is adapted to the size of the dust collector bag 9 and has a fixing function. The dust collector bag 9 is fitted around the frame 8 and fixed. When the frame 8 is rotated by the first drive motor 403, the dust collector bag 9 will rotate synchronously. A top plate 5 is detachably installed on the top of the box 1. An air outlet pipe 501 is installed in the middle of the top plate 5. The air entering through the air inlet pipe 101 passes through the side of the dust collector bag 9 and enters the dust collector bag 9. Finally, it is discharged upward through the air outlet pipe 501. A fan pump or similar device can be installed in the air outlet pipe 501 to better promote the airflow inside the box 1. The working box 4 contains... A second drive motor 404 is installed on the top side. A cleaning component 11 is rotatably connected to the top side of the working box 4 via a second fixing bracket 402. The cleaning component 11 is located on the side of the dust collector bag 9 and contacts the outer wall of the dust collector bag 9. The bottom end of the cleaning component 11 is connected to the output end of the second drive motor 404. One end of the air inlet pipe 101 extends into the box 1 and is connected to a diffuser pipe 102. A guide frame 7 is provided on the inner side of the box 1 at a position corresponding to the diffuser pipe 102. One end of the guide frame 7 is connected to the inner side wall of the box 1 via a connecting component 6. The other end of the guide frame 7 is connected to the outer side wall of the dust collector bag 9. The air intake pipe 101 is better connected to the outer wall of the dust collector bag 9 by the guide frame 7. The diffuser pipe 102 is interlocked with the middle of the guide frame 7. One end of the exhaust pipe 501 extends into the box 1 and is connected to the gathering cover 502. The bottom end of the gathering cover 502 covers the top of the dust collector bag 9. The air in the dust collector bag 9 is transported to the exhaust pipe 501 through the gathering cover 502. The intake pipe 101 and the cleaning component 11 are located on different sides of the box 1. In this embodiment, the number of cleaning components 11 is set to one, and the number of intake pipes 101 is set to several.

[0035] Please see Figure 2 , 34, 7, the sleeve 8 includes a main frame rod 801, several vertical rods 803 evenly distributed around the main frame rod 801 via crossbars 802, and two collars 804. The two collars 804 are respectively connected to the top and bottom of the vertical rods 803. The outer diameter of the collars 804 corresponds to the inner diameter of the dust collector bag 9, and the distance between the two collars 804 is slightly less than the length of the dust collector bag 9. When the dust collector bag 9 is sleeved, the end of the dust collector bag 9 is rolled up on the collars 804. A clamping assembly 10 is connected to the end of the vertical rod 803 near the main frame rod 801 to fix the end of the dust collector bag 9. The lower part of the rod 801 is rotatably connected to the first fixed frame 401. The bottom end of the main frame rod 801 is connected to the output end of the first drive motor 403. A fixed plate 806 is fixedly connected to the lower part of the main frame rod 801. A pressure plate 805 is sleeved on the main frame rod 801 and below the fixed plate 806. A second elastic element 807 is sleeved between the main frame rod 801, the fixed plate 806, and the pressure plate 805. The two ends of the second elastic element 807 are connected to the fixed plate 806 and the pressure plate 805, respectively. After the dust collector bag 9 is installed, the bottom end of the dust collector bag 9 is pressed by the pressure plate 805 at the top of the second elastic element 807, so that the air in the dust collector bag 9 will not be discharged downward.

[0036] Please see Figure 2 , 10 The clamping assembly 10 includes a connecting rod 1001 connected to the vertical rod 803, a threaded sleeve 1002 connected to the end of the connecting rod 1001, and a threaded rod 1003 threadedly connected to the threaded sleeve 1002. A pressure block 1004 is connected to one end of the threaded rod 1003 near the collar 804, and a handle 1005 is connected to the other end of the threaded rod 1003. In this embodiment, the threaded rod 1003 and the threaded sleeve 1002 are inclined relative to the vertical rod 803, that is, the end of the threaded rod 1003 connected to the handle 1005 faces towards... The main frame rod 801 is positioned in the middle so that when the dust collector bag 9 is fitted and fixed, the operator can better reach into the housing 1 and turn the handle 1005 on the clamping assembly 10 located below. The inner side wall of the collar 804 is provided with an adapter groove 808 at the position corresponding to the threaded rod 1003. The end of the dust collector bag 9 is rolled onto the collar 804. By rotating the threaded rod 1003 at the bottom end of the handle 1005, the bottom pressure block 1004 moves and squeezes part of the end of the dust collector bag 9 into the adapter groove 808 to further strengthen the fixation. Example 2

[0037] See Figure 1 , 2Based on Embodiment 1, the top of the guide frame 7 near the sleeve 8 has an arc-shaped groove 701 that matches the shape and size of the collar 804. The bottom of the guide frame 7 has an opening 702. The arc-shaped groove 701 fits against the outer wall of the dust collector bag 9. The dust filtered and blocked by the dust collector bag 9 is discharged into the dust collection hopper 3 through the opening 702. The end of the guide frame 7 away from the sleeve 8 has a circular hole 703 with an inner diameter that matches the outer diameter of the diffuser tube 102. Several diversion tubes 103 are arranged in a ring inside the diffuser tube 102 to allow air to diffuse better into the guide frame 7.

[0038] Please see Figure 5 The connecting assembly 6 includes a straight rod 601, a connecting sleeve 604, and a right-angle rod 605. The straight rod 601 is inserted and connected to the side wall of the housing 1. One end of the straight rod 601 is connected to the end of the guide frame 7 away from the sleeve 8. A first elastic element 602 is sleeved on the straight rod 601. The two ends of the end elastic element are respectively connected to the outer side wall of the guide frame 7 and the inner side wall of the housing 1. The connecting sleeve 604 is connected to the other end of the straight rod 601. A limiting plate 603 is fixedly connected to the straight rod 601. One side of the limiting plate 603 can abut against the outer side wall of the housing 1. The limiting plate 603 prevents the guide frame 7 from excessively squeezing the outer wall of the dust collector bag 9, thereby hindering the rotation of the dust collector bag 9. One end of the right-angle rod 605 is connected to the connecting sleeve. 604 is rotatably connected, and the other end of the right-angle rod 605 is connected to the abutment plate 606. When installing the dust collector bag 9, the straight rod 601 is pulled away from the housing 1. The guide frame 7 moves relative to the diffuser tube 102 through the circular hole 703. The right-angle rod 605 is rotated so that the abutment plate 606 abuts against the outer wall of the housing 1. At this time, there is a large gap between the sleeve 8 and the guide frame 7 to facilitate the installation of the dust collector bag 9. After the dust collector bag 9 is installed, the right-angle rod 605 is rotated so that the abutment plate 606 does not abut against the outer wall of the housing 1. Under the action of the first elastic element 602, the guide frame 7 approaches the dust collector bag 9, so that the arc groove 701 fits against the outer wall of the dust collector bag 9, thereby allowing the air in the guide frame 7 to better contact and pass through the dust collector bag 9 when it flows. Example 3

[0039] See Figure 1 , 3 8. Based on Embodiment 1, the cleaning assembly 11 includes a first rotating rod 1101 and a first cleaning roller 1102 installed on the upper part of the first rotating rod 1101. The lower part of the first rotating rod 1101 is rotatably connected to the second fixed frame 402. The bottom end of the first rotating rod 1101 is connected to the output end of the second drive motor 404. The first cleaning roller 1102 has cleaning bristles. The cleaning bristles contact the outer wall of the dust collector bag 9. The first drive motor 403 drives the first rotating rod 1101 to rotate, thereby driving the cleaning bristles to rotate to clean the outer wall of the dust collector bag 9.

[0040] Please see Figure 1 , 3 8. It also includes a tapping assembly 12 disposed beside the cleaning assembly 11. The tapping assembly 12 includes a second rotating rod 1201, a side rod 1202 connected to the side wall of the second rotating rod 1201, and a second cleaning roller 1203 mounted on the side rod 1202. The side rod 1202 is shaped like a right angle with one end longer than the other. A drive gear 1103 is connected to the first rotating rod 1101. The lower part of the second rotating rod 1201 is rotatably connected to the second fixed frame 402. A driven gear 1204 is mounted on the second rotating rod 1201. The drive gear... 1103 meshes with the driven gear 1204. When the first rotating rod 1101 rotates, the second rotating rod 1201 rotates synchronously through the cooperation of the driving gear 1103 and the driven gear 1204, which in turn drives the side rod 1202 to rotate. When the side rod 1202 rotates, it drives the second cleaning roller 1203 to intermittently knock the outer wall of the dust collector bag 9, so that the dust attached to the dust collector bag 9 can be shaken off. In conjunction with the first cleaning roller 1102, it further improves the cleaning effect on the outer wall of the dust collector bag 9. The second cleaning roller 1203 is soft and will not damage the dust collector bag 9 when it is knocked.

[0041] Working principle: First, the dust collector bag 9 is placed on the frame 8, so that both ends of the dust collector bag 9 are respectively placed on the two collars 804 and the ends of the dust collector bag 9 are rolled up to make full contact with the collars 804. Turning the handle 1005 drives the threaded rod 1003 to rotate, which in turn drives the pressure block 1004 to squeeze the ends of the dust collector bag 9 for fixation. The second elastic element 807 makes the pressure plate 805 press against the bottom end of the dust collector bag 9. The first elastic element 602 makes the side end of the guide frame 7 fit against the outer wall of the dust collector bag 9. The top plate 5 is installed so that the bottom end of the gathering cover 502 presses against the top end of the dust collector bag 9. Then, air dust removal is performed. Air is delivered to the guide frame 7 through the air inlet pipe 101. The air passes through the side of the dust collector bag 9 and enters the interior of the dust collector bag 9. Then, it is discharged from the housing 1 through the air outlet pipe 501. The first drive motor 403 and the second drive motor 404 are connected to the power supply and control system set outside the dust collector through wires. The circuits are connected to meet usage requirements. The first drive motor 403 drives the main frame rod 801 to rotate, which in turn indirectly drives the dust collector bag 9 to rotate, so that all parts of the side of the dust collector bag 9 can fully contact the air input from the air inlet pipe 101. At the same time, the second drive motor 404 drives the first rotating rod 1101 to rotate, which in turn drives the first cleaning roller 1102 to clean the outer wall of the dust collector bag 9. Meanwhile, the transmission between the drive gear 1103 and the driven gear 1204 drives the second rotating rod 1201 to rotate, which in turn drives the second cleaning roller 1203 to intermittently knock on the outer wall of the dust collector bag 9 to improve the cleaning effect. The dust and impurities filtered and blocked by the dust collector bag 9 and the dust and impurities cleaned from the outer wall of the dust collector bag 9 are discharged into the dust collection hopper 3 for collection. After a period of time, the dust and impurities in the dust collection hopper 3 are discharged and transferred through the ash discharge valve 301.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
