[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device with a double-cylinder structure. Background Technology
[0002] The dual-tube filter device is a highly efficient and stable fluid filtration system, mainly used in industrial fields such as hydraulic systems, lubricating oil circulation, chemical processes, and water treatment. Its core feature is the parallel design of the two filter cartridges, enabling online switching, continuous filtration, and maintenance without shutting down the system. It is suitable for high-flow-rate applications or situations requiring high filtration continuity.
[0003] Chinese Patent CN206391709U discloses a filtration device with a dual-cylinder structure, including a filtration unit and a sensing unit. The filtration device includes at least one filter cylinder assembly. The sensing unit includes a differential pressure sensor, which is disposed in the filter cylinder assembly. The differential pressure sensor can monitor the thickness of an impurity layer in the filter cylinder assembly. When the filter cylinder assembly needs to be cleaned according to the monitored value, the filter cylinder assemblies can be switched for use.
[0004] However, the aforementioned publicly available solutions have the following shortcomings: existing filter devices with dual-cylinder structures cannot automatically clean the filter screen, making it easy for the filter screen to be clogged by debris, affecting the filtration effect. At the same time, it is impossible to quickly disassemble the malfunctioning filter cylinder, thus affecting work efficiency. Utility Model Content
[0005] The purpose of this invention is to address the problems in the prior art where the filter screen cannot be automatically cleaned and the malfunctioning filter cartridge cannot be quickly disassembled, and to propose a filtration device with a double-cylinder structure.
[0006] The technical solution of this utility model: A filtration device with a double-cylinder structure, including a base, a support frame disposed on the top of the base, and a filter cylinder disposed inside the support frame; further comprising:
[0007] The installation mechanism is located inside the filter cartridge and is used to assemble and disassemble the internal structure of the cartridge through plug-in connections.
[0008] The cleaning mechanism is located inside the installation mechanism and is used to clean the inside of the installation mechanism by rotating back and forth.
[0009] The rotating ring is mounted on the cleaning assembly. A cleaning brush is mounted on the outer side of the rotating ring. Four cleaning brushes are arranged in a ring around the rotating ring. The rotating ring rotates under the drive of the cleaning mechanism and moves up and down during the rotation, thereby cleaning the device in all directions.
[0010] Preferably, it also includes a conveying assembly, which includes a connecting pipe, an input pipe, and an output pipe;
[0011] The connecting pipe is located at the bottom of the filter cylinder, the input pipe is located on the connecting pipe, the output pipe is located on the side of the filter cylinder, and the top of the filter cylinder is rotatably equipped with an end cap, and the top of the end cap is equipped with a pull ring.
[0012] Preferably, it also includes a flow-draining assembly, which includes a valve, a connecting shaft, and a switch;
[0013] The valve rotation is located inside the connecting pipe, the connecting shaft is located at the top of the valve, the switch is located at the top of the connecting shaft, and the limit block is located inside the connecting pipe.
[0014] Preferably, the installation mechanism includes an installation block, an installation plate, a filter screen, and installation components;
[0015] The mounting plate is located inside the filter cartridge, the mounting block is snapped into the inside of the mounting plate, and the filter screen is located on the side of the mounting block away from the filter cartridge.
[0016] The mounting components are mounted on the mounting block and are used to assemble and disassemble the filter screen and filter cartridge via snap-fit.
[0017] Preferably, the mounting components include a connecting rod, a tie rod, and a movable plate;

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:
[0022] 1. Through the cleaning mechanism, the motor drives the rotating ring to move up and down. During the up and down movement, the rotating ring is driven to rotate through the fixed shaft, so that the cleaning brush can clean the filter screen from all angles. When rotating, the relative movement between the filter screen and the cleaning brush generates friction, which helps to remove stubborn dirt. The up and down movement can change the contact pressure between the cleaning components and the filter screen, further enhancing the cleaning effect.
[0023] 2. By setting up the installation mechanism, pulling the lever causes the insert rod to slide on the installation block, thereby connecting or separating the installation block and the installation plate, thus controlling the installation and disassembly of the filter screen and the filter cartridge. This way, the installation or disassembly of the filter screen can be completed simply by pulling the insert block, which greatly simplifies the operation process and allows the filter screen to be replaced in a shorter time, thereby saving time costs.

Detailed Implementation
[0030] Example 1
[0031] like Figures 1-4As shown, the present invention proposes a filter device with a double-cylinder structure, including a base 1, a support frame 2 disposed on the top of the base 1, a filter cylinder 301 disposed on the inner side of the support frame 2, an installation mechanism, a cleaning mechanism, and a rotating ring 605. The support frame 2 is symmetrically arranged with respect to the top of the base 1 in two parts.
[0032] The mounting mechanism is located inside the filter cartridge 301 and is used to assemble and disassemble the internal structure of the cartridge by means of plugging in.
[0033] The cleaning mechanism is located inside the installation mechanism and is used to clean the inside of the installation mechanism by rotating back and forth.
[0034] A rotating ring 605 is mounted on the cleaning assembly. A cleaning brush 606 is mounted on the outer side of the rotating ring 605. Four cleaning brushes 606 are arranged in a ring around the rotating ring 605. The rotating ring 605 rotates under the drive of the cleaning mechanism and moves up and down during the rotation, thereby cleaning the device in all directions.
[0035] The conveying assembly includes a connecting pipe 302, an input pipe 303, and an output pipe 304. The connecting pipe 302 is located at the bottom of the filter cylinder 301 and has two output ends, each of which is connected to the bottom of the filter cylinder 301. The input pipe 303 is located on the connecting pipe 302 and its bottom is used to connect to the input end of the material. The output pipe 304 is located on the side of the filter cylinder 301 and is used to discharge the filtered material. An end cap 305 is rotatably mounted on the top of the filter cylinder 301, and a pull ring 306 is mounted on the top of the end cap 305. Pulling the pull ring 306 causes the end cap 305 to rotate, thereby opening and closing the filter cylinder 301.
[0036] The flow-guiding assembly includes a valve 401, a connecting shaft 402, and a switch 403. The valve 401 is rotatably disposed inside the connecting pipe 302, the connecting shaft 402 is disposed on top of the valve 401, and the switch 403 is disposed on top of the connecting shaft 402. A limiting block 404 is disposed inside the connecting pipe 302, which is used to limit the valve 401. Rotating the switch 403 drives the connecting shaft 402 to rotate, which in turn drives the valve 401 to rotate, thereby regulating and controlling the material feeding speed of the valve 401. When the valve 401 abuts against the limiting block 404, the valve 401 completely closes the connecting pipe 302, thereby stopping the input of material.
[0037] The mounting mechanism includes a mounting block 502, a mounting plate 503, a filter screen 501, and a mounting assembly. The mounting plate 503 is disposed inside the filter cartridge 301, the mounting block 502 is snapped onto the inside of the mounting plate 503, and the filter screen 501 is disposed on the side of the mounting block 502 away from the filter cartridge 301. The mounting assembly is disposed on the mounting block 502 and is used to assemble and disassemble the filter screen 501 and the filter cartridge 301 by snapping them together. The mounting assembly includes a connecting rod 504, a pull rod 505, and a movable plate 506. The connecting rod 504 is slidably mounted on the mounting block 502. The pull rod 505 is located at the top of the connecting rod 504, and the movable plate 506 is located at the bottom of the connecting rod 504. A spring 509 is located at the top of the movable plate 506, and the top of the spring 509 is connected to the top of the inner side of the mounting block 502. A rotating rod 507 is rotatably mounted at the bottom of the movable plate 506. An insert block 508 is rotatably mounted at the end of the rotating rod 507 away from the movable plate 506. The outer side of the insert block 508 is slidably connected to the side of the mounting block 502. The pull rod 505 pulls the connecting rod 504, causing the movable plate 506 to move. The movable plate 506, through the rotating rod 507, causes the insert block 508 to slide, thereby controlling the insert block 508 to connect or detach the mounting block 502 and the mounting plate 503, thus controlling the installation and removal of the filter screen 501.
[0038] Example 2
[0039] like Figure 5 As shown, this utility model proposes a filter device with a double-cylinder structure. Compared with Embodiment 1, this embodiment details the structure of the cleaning mechanism.
[0040] The cleaning mechanism includes a connecting frame 601, a motor 602, a threaded rod 603, and a movable frame 604. The connecting frame 601 is located inside the filter screen 501, the motor 602 is located inside the connecting frame 601, the threaded rod 603 is located at the output end of the motor 602, and the movable frame 604 is threaded onto the outside of the threaded rod 603. The top of the movable frame 604 is in contact with the bottom of a rotating ring 605. A fixed shaft 608 is located at the top of the rotating ring 605, and a connecting plate 607 is slidably mounted on the top of the fixed shaft 608. The bottom of the connecting plate 607 is in contact with the bottom of the threaded rod 603. The top connection activates the motor 602, which drives the threaded rod 603 to rotate. The threaded rod 603, through the connecting plate 607, drives the fixed shaft 608 to rotate. The fixed shaft 608 drives the rotating ring 605 to rotate around the inner side of the filter screen 501, thereby enabling the cleaning brush 606 to clean the inner side of the filter screen 501. At the same time, the rotation of the threaded rod 603 drives the moving frame 604 to move up and down, thereby supporting the rotating ring 605 to move up and down. During the movement, the fixed shaft 608 slides on the connecting plate 607, allowing the cleaning brush 606 to clean the inner side of the filter screen 501 from all angles.
[0041] In summary, when using this utility model, the bottom of the input pipe 303 is connected to the material box. Then, one of the switches 403 is turned to open the valve 401, allowing the material to enter the filter screen 501 through the connecting pipe 302. After being filtered by the filter screen 501, the material is discharged through the output pipe 304. During the filtration process, the motor 602 is started, which drives the threaded rod 603 to rotate. The threaded rod 603 drives the fixed shaft 608 to rotate through the connecting plate 607. The fixed shaft 608 drives the rotating ring 605 to rotate around the inner side of the filter screen 501, thereby allowing the cleaning brush 606 to clean the inner side of the filter screen 501. At the same time, the rotation of the threaded rod 603 drives the moving frame 604 to move up and down, thereby supporting the rotating ring 605 to move up and down. During operation, the fixed shaft 608 slides on the connecting plate 607, allowing the cleaning brush 606 to clean the inside of the filter screen 501 in all directions. When one of the filter screens 501 or the filter cartridge 301 malfunctions, the valve 401 connected to the malfunctioning filter cartridge 301 is rotated, causing the valve 401 to close the connecting pipe 302 at that location and open the other connecting pipe 302. Then, the pull rod 505 is pulled upwards, and the pull rod 505 pulls the connecting rod 504, causing the moving plate 506 to move upwards. The moving plate 506 drives the two insert blocks 508 to slide inwards through the rotating rod 507, thereby causing the insert blocks 508 to detach from the mounting plate 503. Then, the filter screen 501 is disassembled, and the damaged filter screen 501 or filter cartridge 301 is repaired.
[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
