Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically to a PTFE dust collector filter bag with an anti-detachment interface mechanism. Background Technology

[0002] Dust collector filter bags are a type of high-efficiency dust collection filter material. They are made from raw materials such as polyester staple fiber, PPS fiber, PP polypropylene, aramid fiber, and nylon fiber. Their service life is generally 2-4 years. They have good air permeability, high dust collection rate, and are easy to clean. The dust removal efficiency can reach 98.99%. PTFE, or polytetrafluoroethylene, also known as Teflon, is one of the highest-end varieties of bag filter materials.

[0003] Currently, most dust collector filter bags are installed in the tube sheet holes using elastic expansion rings at the bag opening. However, these expansion rings are installed by rebounding and fitting against the inner wall of the tube sheet hole. If errors occur during manual hole cutting, the cut tube sheet hole and the elastic expansion ring may not be the same size, preventing the expansion ring from fitting properly against the inner wall of the tube sheet hole. This can easily lead to the filter bag falling off. Furthermore, if the elastic expansion ring develops quality problems after prolonged use, it may also affect the stability of the filter bag installation, causing it to fall off and affecting dust collection, significantly reducing the practicality of the device. Therefore, we provide a PTFE dust collector filter bag with an anti-detachment interface mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a PTFE dust collector filter bag with an anti-detachment interface mechanism, which solves the problem in the prior art where errors such as manual hole cutting lead to misalignment between the cut perforated plate hole and the elastic expansion ring, resulting in the elastic expansion ring not fitting well against the inner wall of the perforated plate hole, thus easily causing the filter bag to fall off. Moreover, when the elastic expansion ring develops quality problems after long-term use, it may also affect the stability of the filter bag installation, leading to the filter bag falling off and thus affecting the dust collection problem.

[0005] This utility model provides the following technical solution: a PTFE dust collector filter bag with an anti-detachment interface mechanism, including a connecting port, a filter bag body and a tube sheet hole. The filter bag body is inserted into the tube sheet hole. A connecting ring is fixedly connected to the bottom end of the connecting port. The filter bag body is sleeved on the outside of the connecting ring. A limit ring is fixedly sleeved on the upper side of the outer wall of the connecting port. Movable grooves are provided on both sides of the outer wall of the connecting port. An anti-detachment mechanism for preventing the filter bag body from falling off is provided in each set of movable grooves. A disassembly and assembly component for installing the filter bag body is provided on the outer surface of the filter bag body near the connecting ring.

[0006] Through the above technical solution, the limiting ring can work in conjunction with the anti-detachment mechanism to play a limiting role and is used for installing the filter bag body.

[0007] As a preferred embodiment of the above technical solution, each set of anti-detachment mechanisms includes a movable block and an adjustment component. Each set of movable blocks is slidably installed in a movable groove via the adjustment component. Each set of movable blocks has a sliding groove at its outer end. A spring is installed on the inner side of each set of sliding grooves. A limit block is slidably installed at the opening of each set of sliding grooves, and the inner end of the limit block is connected to the spring. A pull rod is connected to the inner end of the limit block, and the end of the pull rod away from the limit block passes through the movable block and the connection port and extends into the interior of the connection port. A guide opening is provided on the inner wall of the movable groove, and the pull rod slides within the guide opening.

[0008] The above technical solution allows the tube sheet to be clamped between the limiting ring and the limiting block, thus completing the installation of the filter bag body. This makes the filter bag body installation more stable and better prevents the filter bag body from falling off.

[0009] As a preferred embodiment of the above technical solution, a rubber pad is glued to the top of each set of limiting blocks.

[0010] The above technical solution increases the friction between the limiting block and the perforated plate, thus making the clamping more stable.

[0011] As a preferred embodiment of the above technical solution, each set of adjustment components includes a mounting groove, each set of mounting grooves is opened on one side of the inner wall of the movable groove, each set of mounting grooves has a screw rotatably installed inside, each set of screws has a threaded sleeve on its surface, each set of screw sleeves is fixedly connected to the movable block, and each set of screws has a connecting rod connected to its top end.

[0012] The above technical solution allows the spacing between the limiting ring and the limiting block to be adjusted according to the thickness of the perforated plate, enabling the limiting ring and the limiting block to clamp the perforated plate more tightly, thus greatly increasing the stability of the device.

[0013] As a preferred embodiment of the above technical solution, the top end of each set of connecting rods extends to the top end of the connection port, and a knob is installed at the top end of each set of connecting rods.

[0014] The above technical solution makes it more convenient to rotate the connecting rod by turning the knob.

[0015] As a preferred embodiment of the above technical solution, the disassembly and assembly assembly includes a first limiting sleeve and a second limiting sleeve. Both the first limiting sleeve and the second limiting sleeve are fitted onto the outer surface of the filter bag body. Connecting blocks are connected to both sides of the outer wall of the first limiting sleeve and the second limiting sleeve. A through hole is opened at one end of each set of connecting blocks. A bolt is inserted into every two sets of through holes. A nut is threaded onto one side of the bolt.

[0016] The above technical solution allows the filter bag body to be installed and fixed on the outer end of the connecting ring, and the filter bag body to be disassembled from the outer end of the connecting ring, thereby separating the connection port from the filter bag body and making it easier to clean or replace the filter bag body.

[0017] As a preferred embodiment of the above technical solution, the upper outer wall of the filter bag body and the outer wall of the connecting ring are provided with insertion holes and slots at equal intervals, and the inner walls of the first limiting sleeve and the second limiting sleeve are connected with insertion rods at equal intervals, and each set of insertion rods passes through the insertion hole and is inserted into the slot.

[0018] The above technical solutions make the installation of the filter bag body by the limiting sleeve one and the limiting sleeve two more stable and less likely to fall off.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention, by incorporating a disassembly and assembly component, allows the connection port to be fixedly installed to the filter bag body, making the installation of the filter bag body easier. Furthermore, by combining an anti-detachment mechanism and an adjustment component, the tube sheet can be clamped between the limiting ring and the limiting block. This ensures the filter bag body is more securely installed within the tube sheet holes, better preventing it from falling off and thus minimizing disruption to the dust removal operation of the filter bag body, significantly increasing the practicality of the device.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution: a PTFE dust collector filter bag with an anti-detachment interface mechanism, including a connection port 1, a filter bag body 5, and a perforated plate 7. The filter bag body 5 is inserted into the perforated plate 7. A connecting ring 4 is fixedly connected to the bottom end of the connection port 1. The filter bag body 5 is sleeved on the outside of the connecting ring 4. A limit ring 11 is fixedly sleeved on the upper side of the outer wall of the connection port 1. Movable grooves 12 are provided on both sides of the outer wall of the connection port 1. Each set of movable grooves 12 is provided with an anti-detachment mechanism 2 to prevent the filter bag body 5 from falling off. Each set of anti-detachment mechanisms 2 includes... The movable block 21 and the adjusting component 3 are configured such that each movable block 21 is slidably installed in the movable groove 12 via the adjusting component 3. Each movable block 21 has a sliding groove 22 at its outer end, and a spring 23 is installed on the inner side of each sliding groove 22. A limiting block 24 is slidably installed at the opening of each sliding groove 22, and the inner end of the limiting block 24 is connected to the spring 23. This structure allows the filter bag body 5 and the connecting port 1 to be inserted into the perforated plate hole 7, causing the edge of the perforated plate hole 7 to press and push the limiting block 24, pushing it into the sliding groove 22 and compressing the spring 23. When the connecting port 1 drives the limiting ring 11 to fit against the top of the tube sheet, the connecting port 1 drives the limiting block 24 to move through the tube sheet hole 7 to the bottom of the tube sheet. The limiting block 24 is then pushed out partly by the spring force of the spring 23, thus clamping the tube sheet between the limiting ring 11 and the limiting block 24, completing the installation of the filter bag body 5. This makes the filter bag body 5 more securely installed, better preventing the filter bag body 5 from falling off, and thus less likely to affect the dust removal work of the filter bag body 5, greatly increasing the practicality of the device. The inner end of the limiting block 24 is connected to... There is a pull rod 26, and the end of the pull rod 26 away from the limiting block 24 passes through the movable block 21 and the connecting port 1 and extends into the interior of the connecting port 1. The inner wall of the movable groove 12 is provided with a guide opening 13. The pull rod 26 slides in the guide opening 13. The pull rod 26 makes it easier to pull the limiting block 24 into the sliding groove 22, thereby releasing the clamping of the tube sheet and removing the filter bag body 5 from the tube sheet hole 7. The top of each set of limiting blocks 24 is glued with a rubber pad 25, which increases the friction between the limiting block 24 and the tube sheet, thereby making the clamping more stable.

[0030] It should be noted that the hole 7 in the tube sheet is made on the tube sheet and is used to install the dust collector filter bag, while the tube sheet is the steel partition plate at the top of the dust collector.

[0031] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, each set of adjustment components 3 includes a mounting groove 31, which is formed on one side of the inner wall of the movable groove 12. A screw 32 is rotatably mounted inside each mounting groove 31. A threaded sleeve 33 is threaded onto the surface of each screw 32, and each threaded sleeve 33 is fixedly connected to the movable block 21. A connecting rod 34 is connected to the top of each screw 32, and the top of each connecting rod 34 extends to the top of the connection port 1. A knob 35 is mounted on the top of each connecting rod 34. This structure allows rotating the knob 35 to rotate the connecting rod 34. 34 drives the screw 32 to rotate. Through the rotation of the thread, the screw 32 drives the screw sleeve 33 to move longitudinally in the mounting groove 31. The screw 32 can then drive the movable block 21 to move longitudinally in the movable groove 12, thereby causing the movable block 21 to drive the limiting block 24 to move longitudinally. At the same time, the limiting block 24 will also drive the pull rod 26 to slide in the guide opening 13. In this way, the distance between the limiting ring 11 and the limiting block 24 can be adjusted according to the thickness of the tube sheet, so that the limiting ring 11 and the limiting block 24 can clamp the tube sheet more tightly, greatly increasing the stability of the device.

[0032] As one implementation method in this embodiment, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a disassembly and assembly assembly 6 for installing the filter bag body 5 is provided on the outer surface of the filter bag body 5 near the connecting ring 4. The disassembly and assembly assembly 6 includes a first limiting sleeve 61 and a second limiting sleeve 62, both of which are fitted onto the outer surface of the filter bag body 5. Connecting blocks 64 are connected to both sides of the outer wall of the first limiting sleeve 61 and the second limiting sleeve 62. A through hole 65 is opened through one end of each set of connecting blocks 64. A bolt 66 is inserted into each pair of through holes 65. A nut 67 is threaded onto one side of the bolt 66. Insertion holes 51 and slots 41 are equally spaced on the upper side of the outer wall of the filter bag body 5 and the outer wall of the connecting ring 4. The inner walls of sleeve 61 and limiting sleeve 62 are equidistantly connected with insert rods 63. Each set of insert rods 63 passes through the insertion hole 51 and is inserted into the slot 41. This structure allows the locking of limiting sleeve 61 and limiting sleeve 62 to be released by using tools to unscrew the nut 67 from the bolt 66 and then remove the bolt 66 from the through hole 65. This opens the limiting sleeve 61 and limiting sleeve 62 until the limiting sleeve 61 and limiting sleeve 62 pull the insert rods 63 out of the slot 41 and insertion hole 51. This allows the filter bag body 5 to be removed from the connecting ring 4, completing the disassembly and making it easier to clean or replace the filter bag body 5.

[0033] It should be noted that although the connecting block 64 is the outer wall of the connecting limit sleeve 1 61 and the limit sleeve 2 62 and is protruding, the connecting block 64 is relatively small and does not exceed the outer diameter range of the connecting port 1, so it will not easily affect the installation of the filter bag body 5.

[0034] Working principle: To install the filter bag body 5, simply align the filter bag body 5 and the connecting port 1 with the tube sheet hole 7 and insert them into the tube sheet hole 7. At this time, the edge of the tube sheet hole 7 will squeeze and push the limiting block 24, pushing the limiting block 24 into the slide groove 22 to compress the spring 23, until the connecting port 1 drives the limiting ring 11 to fit against the top of the tube sheet. This allows the connecting port 1 to drive the limiting block 24 through the tube sheet hole 7 and move to the bottom of the tube sheet. The limiting block 24 will then be pushed out partly by the spring force of the spring 23, thus clamping the tube sheet in the limiting ring. The filter bag body 5 is installed between the 11 and the limiting block 24, making the filter bag body 5 more secure and better preventing the filter bag body 5 from falling off. This makes it less likely to affect the dust removal work of the filter bag body 5 and greatly increases the practicality of the device. If the filter bag body 5 needs to be removed from the tube sheet hole 7, simply pull the pull rod 26 to move the limiting block 24 into the slide groove 22. At this time, the clamp on the tube sheet can be released, and then the connecting port 1 can be pulled to remove the filter bag body 5 from the tube sheet hole 7 to complete the disassembly.

[0035] If the distance between the limiting ring 11 and the limiting block 24 needs to be adjusted according to the thickness of the tube sheet, simply turn the knob 35 to drive the connecting rod 34 to rotate. The connecting rod 34 drives the screw 32 to rotate. Through the screw rotation, the screw 32 drives the screw sleeve 33 to move longitudinally in the mounting groove 31. The screw 32 can then drive the movable block 21 to move longitudinally in the movable groove 12, thereby causing the movable block 21 to drive the limiting block 24 to move longitudinally. At the same time, the limiting block 24 will also drive the pull rod 26 to slide in the guide opening 13. In this way, the distance between the limiting ring 11 and the limiting block 24 can be adjusted according to the thickness of the tube sheet, so that the limiting ring 11 and the limiting block 24 can clamp the tube sheet more tightly.

[0036] Finally, if it is necessary to separate the filter bag body 5 from the connecting port 1, simply use a tool to unscrew the nut 67 from the bolt 66 in sequence, and then remove the bolt 66 from the through hole 65. This will unlock the locking of the first limiting sleeve 61 and the second limiting sleeve 62, thereby opening the first limiting sleeve 61 and the second limiting sleeve 62 until the first limiting sleeve 61 and the second limiting sleeve 62 drive the insertion rod 63 to be pulled out of the slot 41 and the insertion hole 51. In this way, the filter bag body 5 can be removed from the connecting ring 4, completing the disassembly and making it easier to clean or replace the filter bag body 5.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
