Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial waste gas treatment technology, and more specifically, to a replaceable purification filter element for industrial use. Background Technology
[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These substances enter the human body through the respiratory tract via different pathways; some cause direct harm, while others accumulate and can further endanger human health, thus requiring appropriate filters for treatment.
[0003] Because industrial waste gas contains high concentrations of particulate matter and viscous substances, the filter elements in the filter will quickly become clogged, damaged, or fail. Therefore, the filter elements need to be replaced frequently to maintain the purification effect. However, when replacing the filter elements of existing filters, since the filter elements are installed deep inside the equipment, it is necessary to remove the outer shell parts first to access the filter elements, which increases the time required for filter element replacement and may also cause damage to other parts of the equipment during the disassembly process. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an industrial replaceable purification filter element. The technical problem to be solved by the present invention is that when replacing the filter element of the existing filter, it is necessary to remove the outer shell and other parts before contacting the filter element, which increases the time required for replacing the filter element and may also cause damage to other parts of the equipment during the disassembly process.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An industrial replaceable purification filter element includes a filter cartridge. An inlet pipe and an outlet pipe are fixedly connected to both sides of the filter cartridge. A turntable is rotatably connected inside the filter cartridge. Multiple filter elements are symmetrically installed inside the turntable via bolts. An opening is provided on the filter cartridge. Multiple positioning holes are symmetrically provided on the outer side of the turntable. The rotation of the turntable is restricted by a positioning mechanism on the outer side of the filter cartridge. A connecting seat is fixedly installed on both sides of the turntable. Multiple sealing airbags are connected to the outer side of each connecting seat, and each sealing airbag is fitted onto the outer side of a filter element. Extrusion cylinders are fixedly installed on both outer sides of the filter cartridge. Each extrusion cylinder contains an air injection mechanism, and each air injection mechanism is connected to a corresponding connecting seat.
[0007] like Figure 1-3As shown, the specific implementation method is as follows: By setting up a turntable and a filter element, the filter element can be rotated by rotating the turntable, thereby aligning the air inlet pipe and the air outlet pipe. At the same time, the filter element can be assembled and disassembled in an open space without disassembling the outer shell and other parts, reducing the replacement time of the filter element. Meanwhile, the positioning mechanism and positioning holes can restrict the rotation of the turntable to prevent the turntable from shaking. At the same time, the extrusion cylinder, air injection mechanism, and sealing airbag can be used to inject air into the sealing airbag, thereby expanding the sealing airbag and filling the gap between the side wall of the filter cylinder and the side of the turntable, thereby preventing exhaust gas leakage.
[0008] In a preferred embodiment, each of the gas injection mechanisms includes a threaded rod, and each threaded rod is threadedly connected to the top surface of the corresponding extrusion cylinder. One end of each threaded rod extends into the extrusion cylinder and is rotatably connected to a pressure plate. An injection airbag is fixedly installed on the bottom wall of each extrusion cylinder, and the bottom surface of each pressure plate abuts against the top surface of the corresponding injection airbag. One end of each injection airbag is connected to a corresponding connecting seat via a rotary joint.
[0009] In a preferred embodiment, the positioning mechanism includes a U-shaped seat, which is fixedly installed on the outside of the filter cylinder. A positioning rod is elastically slidably connected to the top surface of the U-shaped seat, and one end of the positioning rod extends into a positioning hole corresponding to the position. A top plate is fixedly installed on the top of the U-shaped seat, and a spring is installed between the bottom surface of the top plate and the top surface of the U-shaped seat.
[0010] In a preferred embodiment, each of the connecting seats has a plurality of connecting pipes fixed to and connected to its outer side, and each connecting pipe is connected to a sealing airbag at a corresponding position.
[0011] In a preferred embodiment, a handle is fixedly installed at the end of the threaded rod away from the pressure plate, and a ball is rotatably connected at the end of the positioning rod away from the top plate.
[0012] In a preferred embodiment, a plurality of annular sliders are symmetrically mounted on the outer side of the turntable, and each annular slider is slidably connected to the side wall of the filter cartridge.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by setting up a turntable, filter element, opening, positioning rod, positioning hole, spring and other devices, realizes that the new filter element can be quickly replaced with the old filter element by rotating the turntable, and under the action of the spring, it is firmly locked in the positioning by the positioning rod to realize the positioning of the turntable. Thus, the old filter element can be assembled and disassembled in an open space without disassembling the outer shell and other parts, thereby reducing the filter element replacement time.
[0015] 2. This utility model, by setting up a threaded rod, an air-injection bladder, a sealing bladder, a pressure plate, and other devices, realizes that turning the handle drives the threaded rod to move downward, and drives the pressure plate to squeeze the air-injection bladder, thereby injecting the gas in the air-injection bladder into the sealing bladder, causing the sealing bladder to expand and fill the gap between the filter cartridge and the turntable, thus preventing the leakage of waste gas.
[0016] In summary, this utility model is simple to operate and can quickly replace the old filter element with the new one. It can also be assembled and disassembled in an open space without disassembling the outer shell or other parts, reducing the filter element replacement time. At the same time, the sealing airbag expands and fills the gap between the filter cylinder and the turntable to prevent exhaust gas leakage. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Reference Figure 1-3An industrial replaceable purification filter element includes a filter cylinder 1. An air inlet pipe 2 and an air outlet pipe 3 are fixed and connected to both sides of the filter cylinder 1. A turntable 5 is rotatably connected inside the filter cylinder 1. Multiple filter elements 7 are symmetrically installed inside the turntable 5 by bolts. An opening 8 is opened on the filter cylinder 1. Multiple positioning holes 13 are symmetrically opened on the outer side of the turntable 5. The rotation of the turntable 5 is restricted on the outer side of the filter cylinder 1 by a positioning mechanism. A connecting seat 14 is fixedly installed on both sides of the turntable 5. Multiple sealing air bags 16 are connected to the outer side of each connecting seat 14. Each sealing air bag 16 is sleeved on the outer side of the filter element 7. An extrusion cylinder 4 is fixedly installed on both outer sides of the filter cylinder 1. Each extrusion cylinder 4 is provided with an air injection mechanism. Each air injection mechanism is connected to the corresponding connecting seat 14.
[0023] like Figure 1-3 As shown, the specific implementation method is as follows: By setting up a turntable 5 and a filter element 7, the filter element 7 can be rotated by rotating the turntable 5, thereby aligning the air inlet pipe 2 and the air outlet pipe 3. At the same time, the filter element 7 can be assembled and disassembled in an open space without disassembling the outer shell and other parts, reducing the replacement time of the filter element 7. Meanwhile, the rotation of the turntable 5 can be restricted by the positioning mechanism and the positioning hole 13 to prevent the turntable 5 from shaking. At the same time, the compression cylinder 4, the air injection mechanism, and the sealing airbag 16 can be used to inject air into the sealing airbag 16, thereby inflating the sealing airbag 16 and filling the gap between the side wall of the filter cylinder 1 and the side of the turntable 5, thereby preventing exhaust gas leakage.
[0024] Each injection mechanism includes a threaded rod 19, and each threaded rod 19 is threadedly connected to the top surface of the corresponding extrusion cylinder 4. One end of each threaded rod 19 extends into the extrusion cylinder 4 and is rotatably connected to a pressure plate 20. An injection airbag 21 is fixedly installed on the bottom wall of each extrusion cylinder 4, and the bottom surface of each pressure plate 20 abuts against the top surface of the corresponding injection airbag 21. One end of each injection airbag 21 is connected to the corresponding connecting seat 14 through a rotary joint 15. It is worth noting that the thread has self-locking properties. When the threaded rod 19 is rotated and threadedly connected to the extrusion cylinder 4, the threaded rod 19 moves downward and causes the pressure plate 20 to squeeze the injection airbag 21. As a result, the gas in the injection airbag 21 is squeezed into the connecting seat 14 through the rotary joint 15, thereby causing the sealing airbag 16 to expand.
[0025] The positioning mechanism includes a U-shaped seat 9, which is fixedly installed on the outside of the filter cylinder 1. A positioning rod 10 is elastically slidably connected to the top surface of the U-shaped seat 9, and one end of the positioning rod 10 extends into the positioning hole 13 corresponding to the position. A top plate 11 is fixedly installed on the top of the U-shaped seat 9. A spring 12 is installed between the bottom surface of the top plate 11 and the top surface of the U-shaped seat 9. The positioning rod 10 can be firmly locked in the positioning hole 13 by the spring 12, thereby fixing the turntable 5.
[0026] Each connecting seat 14 has multiple connecting pipes 17 fixed to and connected to its outer side, and each connecting pipe 17 is connected to a corresponding sealing airbag 16.
[0027] A handle 18 is fixedly installed at the end of the threaded rod 19 away from the pressure plate 20. A rotating ball is rotatably connected at the end of the positioning rod 10 away from the top plate 11. When the turntable 5 rotates, the rotating ball rotates along the outside of the turntable 5 and automatically locks into the positioning hole 13.
[0028] Multiple annular sliders 6 are symmetrically installed on the outer side of the turntable 5, and each annular slider 6 is slidably connected to the side wall of the filter cylinder 1.
[0029] When using this utility model, firstly, the threaded rod 19 can be rotated by turning the handle 18, causing the threaded rod 19 to slide outward, so that the pressure plate 20 no longer squeezes the air-filled bladder 21, thereby the air-filled bladder 21 deforms and resets itself, and the gas in the sealed bladder 16 is extracted through the connecting seat 14. Then, the positioning rod 10 can be pulled outward through the top plate 11. Next, the turntable 5 is rotated. When the turntable 5 rotates, the rotating ball connected to the bottom end of the positioning rod 10 slides along the outer wall of the turntable 5. When the turntable 5 rotates a certain angle, the rotating ball is locked into the positioning hole 13 under the action of the spring 12, thereby realizing the positioning of the turntable 5. At this time, the new filter element 7 is positioned between the air inlet pipe 2 and the air outlet pipe 3, and the turntable 5 is limited by the positioning rod 10, so that it cannot rotate.
[0030] Next, turn the handle 18 in the opposite direction to move the threaded rod 19 down, thereby squeezing the air injection bladder 21 through the pressure plate 20 and injecting the gas in the air injection bladder 21 into the sealing bladder 16. This fills the gap between the filter cartridge 1 and the turntable 5 through the sealing bladder 16, preventing exhaust gas leakage. At this time, the old filter element 7 is at the opening 8, so the filter element 7 can be quickly replaced and disassembled with bolts.
[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
