Description

Technical Field

[0001] This application relates to the technical field of filtration equipment, and in particular to a cartridge filter. Background Technology

[0002] The core components of a cartridge filter include the filter media, the support structure, and the housing. The support structure is integrated with the filter media to provide support and prevent local collapse. The housing provides external support and protection for the filter media. After the mixed fluid enters the housing, it is filtered by the filter media to produce a purer fluid.

[0003] The related technology proposes a dust collector filter cartridge that is easy to replace. By setting up a fixing mechanism, a filter cartridge mechanism is set up inside the fixing mechanism. The upper support plate and the limiting ring cooperate to clamp the filter cartridge, and the upper fixing ring and the reinforcing threaded pin clamp the threaded ring. After clamping, the filter cartridge mechanism is fixed by the connecting threaded pin and the reinforcing threaded pin. After fixing, the dust hopper is connected by the threaded connection between the connecting ring and the threaded ring. When the filter cartridge needs to be replaced, the connecting ring can be rotated by grasping the handle, and the dust hopper can be removed separately to realize the individual disassembly and assembly of the filter cartridge mechanism.

[0004] The problem with the related technology is that when the filter cartridge surface is heavily dusty, although the method of quickly disassembling and assembling the dust removal filter cartridge can facilitate cleaning, the process of disassembling or replacing the filter cartridge wastes a lot of time, affecting the normal operation of the equipment and failing to meet actual production needs. Utility Model Content

[0005] To facilitate dust cleaning, minimize the impact on equipment operation, and meet actual production needs, this application provides a cartridge filter.

[0006] The cartridge filter provided in this application adopts the following technical solution:

[0007] A cartridge filter includes a housing and a filter assembly, which are sealed together. A dust removal component is disposed between the housing and the filter assembly. The dust removal component includes a driver, a rotating part, and a conductive part. The conductive part cooperates with the filter assembly. The rotating part is coaxially arranged with the conductive part and located outside the conductive part. The driver is connected to the rotating part to drive the rotating part to rotate. Cooperating elastic vibrating blocks and protrusions are respectively provided on the rotating part and the conductive part. The dust removal component is disposed at one end of the filter assembly, and a collection box is disposed at the other end of the filter assembly.

[0008] Optionally, the outer surface of the rotating part is formed with a plurality of equally spaced racks, the driver includes a motor and a gear mounted on the output end of the motor, the gear is disposed on one side of the rotating part and meshes with it, and the rotating part is rotatably connected to the housing.

[0009] Optionally, the elastic vibrating block includes a block body and an elastic element. One end of the elastic element is fixed to the inner wall of the rotating part, and the other end is connected to the block body. The elastic element can be stretched or compressed radially along the rotating part. The length of the elastic element in its natural state is greater than the difference between the radius of the rotating part and the conducting part.

[0010] Optionally, the protrusion is integrally formed on the side of the conductive part facing the rotating part. The protrusion extends radially toward the rotating part and has a mating surface and a back surface. The mating surface and the back surface are distributed sequentially in the rotation direction of the rotating part, and the mating surface smoothly transitions to the back surface in an arc shape.

[0011] Optionally, the housing has openings at both ends, and the filter assembly is inserted into the housing. A mixed fluid inlet is formed at one end of the filter assembly, which communicates with its interior. A clean fluid outlet is formed on the surface of the housing. The mixed fluid inlet and the clean fluid outlet are separated by the filter medium of the filter assembly.

[0012] Optionally, the filter assembly includes a filter element, a first sealing cover, and a second sealing cover, with the first and second sealing covers respectively disposed at both ends of the filter element, and the mixed fluid inlet formed on the first sealing cover.

[0013] Optionally, the second sealing cover has a through hole in the middle that connects to the inside of the filter element, and a connecting part that extends outward in an annular shape is formed at the through hole. The dust removal component is located at one end of the filter component near the inlet of the mixed fluid, and the collection box is located at the other end of the filter component. The collection box and the connecting part are detachably connected.

[0014] Optionally, the filter assembly further includes a support frame, which includes an annular support member and a support rod. The support rod is fixedly connected to the annular support member, and the filter element is sleeved on the outside of the support frame.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. By installing a dust removal component between the housing and the filter assembly, when dust accumulates on the filter assembly and clogs the filter pores to a certain extent, the rotating part can be started by activating the driver to rotate. The rotating part drives the elastic vibrating block to rotate synchronously. The elastic vibrating block is compressed when it passes the protrusion and resets after passing the protrusion. Through the action of elastic force, the elastic vibrating block applies vibration force to the transmission part when it resets. This vibration force is transmitted to the filter assembly, and dust is cleaned when the filter assembly vibrates. This can reduce the frequency of filter assembly replacement and maintenance, thereby reducing the impact on equipment operation and adapting to the needs of actual production.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a cartridge filter. (Refer to...) Figure 1 and Figure 2 The cartridge filter includes a housing 1 and a filter assembly 2, both of which are cylindrical in shape and are coaxially arranged and distributed internally and externally. A filter chamber is formed inside the filter assembly 2, and a discharge chamber is formed between the housing 1 and the filter assembly 2. A clean fluid outlet 6 is formed on the surface of the housing 1, and the clean fluid outlet 6 communicates with the discharge chamber. A mixed fluid inlet 5 is formed on the filter assembly 2, and the mixed fluid inlet 5 communicates with the filter chamber. Fluid enters the filter chamber through the mixed fluid inlet 5. As the fluid flows from the filter chamber to the discharge chamber, the filter assembly 2 intercepts target impurities, and the filtered pure fluid enters the discharge chamber and is discharged through the clean fluid outlet 6.

[0025] Reference Figure 1The filter assembly 2 includes a filter element 21, a first sealing cover 22, and a second sealing cover 23. The filter element 21 has a cylindrical structure with openings at both ends. The first sealing cover 22 and the second sealing cover 23 are respectively installed at the two ends of the filter element 21. The filter assembly 2 can be sealed to the outer shell 1 through the first sealing cover 22 and the second sealing cover 23. The aforementioned mixed fluid inlet 5 is provided on the first sealing cover 22. The sealing connection method between the first sealing cover 22, the second sealing cover 23 and the outer shell 1, as well as the specific composition of the filter element 21, adopt existing technology and are not specifically limited here.

[0026] The filter assembly 2 also includes a support frame 24 that provides support for the filter element 21. The support frame 24 includes an annular support member 241 adapted to the cylindrical shape of the filter assembly 2, and support rods 242 extending axially along the filter assembly 2. The support rods 242 are connected to the annular support member 241, and multiple annular support members 241 and multiple support rods 242 cooperate with each other to form a cage-like internal support. The filter element 21 is sleeved on the outside of the support frame 24.

[0027] Reference Figure 1 , Figure 3 and Figure 5 A dust removal component 3 is disposed between the outer casing 1 and the filter component 2. The dust removal component 3 can apply a regular vibration force to the filter component 2, causing the filter element 21 to vibrate and shake off the dust accumulated on the filter element 21. Corresponding to the dust removal component 3, a through hole communicating with the filter chamber is opened in the middle of the second sealing cover 23. An annular outwardly extending connecting part 231 is formed at the through hole, and a collection box 4 is detachably connected to the connecting part 231. Preferably, the collection box 4 adopts a U-shaped box structure, and it can be threadedly connected to the connecting part 231. When the collection box 4 is connected to the connecting part 231, it can communicate with the filter chamber through the through hole. When the dust removal component 3 is working, the dust shaken off from the filter element 21 is collected in the collection box 4.

[0028] Reference Figure 4 and Figure 5 The dust removal assembly 3 includes a driver 31, a rotating part 32, and a conducting part 33. The rotating part 32 and the conducting part 33 are both configured as annular plate structures. The rotating part 32, the conducting part 33, and the filter assembly 2 are coaxially arranged. The conducting part 33 is located on the outside of the filter assembly 2 and is in contact with the filter element 21. The rotating part 32 is located on the outside of the conducting part 33 and can rotate relative to the conducting part 33. An annular groove is reserved between the rotating part 32 and the conducting part 33. The dust removal assembly 3 also includes an elastic vibrating block 34 and a protrusion 35 disposed in the annular groove. The elastic vibrating block 34 is connected to the rotating part 32, and the protrusion 35 is disposed on the conducting part 33.

[0029] Furthermore, the aforementioned driver 31 is connected to the rotating part 32 to drive the rotating part 32 to rotate around its central axis. When the rotating part 32 rotates, the elastic vibrating block 34 rotates accordingly. The elastic vibrating block 34 includes a block body 341 and an elastic element 342. The elastic element 342 is linearly expandable and contractable in the radial direction of the rotating part 32. One end of the elastic element 342 is fixed to the inner wall of the rotating part 32, and the block body 341 is mounted on the other end of the elastic element 342. The aforementioned protrusion 35 is provided in the structure extending towards the rotating part 32. The difference between the radii of the rotating part 32 and the conducting part 33 is less than the length of the elastic element 342 in its natural state, so as to ensure that the elastic element 342 in the annular groove is always in a compressed state.

[0030] With the above structure, when the elastic vibrating block 34 rotates with the rotating part 32 and passes the protrusion 35, the block 341 and the protrusion 35 remain in contact, and the originally compressed elastic element 342 is further compressed; after passing the protrusion 35, the elastic element 342 recovers its deformation, causing the block 341 to extend quickly and contact the transmission part 33, thereby applying a vibrating force to the transmission part 33. The vibrating force is transmitted to the filter element 21 through the transmission part 33, causing the filter element 21 to vibrate to shake off the dust attached to it.

[0031] Preferably, the protrusion 35 is integrally connected to the conductive part 33. The protrusion 35 has a mating surface 351 and a back surface 352. The junction of the mating surface 351 and the back surface 352 is the farthest end of the protrusion 35. The mating surface 351 smoothly transitions to the back surface 352 in an arc shape. The back surface 352 extends radially along the conductive part 33. When the elastic vibrating block 34 rotates with the rotating part 32, it first further compresses the elastic element 342 through the mating surface 351 of the protrusion 35. The arc-shaped mating surface 351 makes the further compression of the elastic element 342 more stable. After passing through the mating surface 351, the elastic element 342 is not blocked by the back surface 352 and can quickly recover its deformation. This recovery deformation force is transmitted to the conductive part 33 through the block 341 to achieve vibration.

[0032] Understandably, in order to make the rapping force on the filter assembly 2 more uniform, the protrusions 35 and the elastic rapping blocks 34 should each be provided in several and evenly distributed in the annular groove.

[0033] Preferably, the connection between the driver 31 and the rotating part 32 can be specifically adopted as follows: a rack 321 with spaced intervals is formed on the outer peripheral surface of the rotating part 32, the driver 31 includes a motor 311 and a gear 312, wherein the gear 312 cooperates with the rack 321, and the driving end of the motor 311 is connected to the gear 312. When the motor 311 is started, the rotating part 32 can be driven to rotate through the meshing between the gear 312 and the rack 321.

[0034] This application provides a cartridge filter. By setting a dust removal component 3 between the outer shell 1 and the filter component 2, when dust accumulates on the filter component 2 and blocks the filter holes to a certain extent, the rotating part 32 can be rotated by starting the driver 31. The rotating part 32 drives the elastic vibrating block 34 to rotate synchronously. The elastic vibrating block 34 is compressed when it passes the protrusion 35 and resets after passing the protrusion 35. Through the action of elastic force, the elastic vibrating block 34 applies a vibration force to the transmission part 33 when it resets. This vibration force is transmitted to the filter component 2. The dust is cleaned when the filter component 2 vibrates, which can reduce the frequency of replacement and maintenance of the filter component 2, thereby reducing the impact on equipment operation and adapting to the needs of actual production.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
