Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a metal filter cartridge structure. Background Technology

[0002] In industrial production processes, metal filter cartridges are widely used in various gas and liquid filtration scenarios. Existing metal filter cartridge structures typically consist of a filter cartridge body with a filter layer on it to intercept impurities. During installation, the top and bottom ends of the filter cartridge body are plugged into interfaces of external equipment. However, existing metal filter cartridges have several problems during use. For example, when cleaning or replacing the filter cartridge, the disassembly and installation process is cumbersome, time-consuming, and labor-intensive. Furthermore, after prolonged use, a significant amount of impurities accumulates on the filter layer, affecting the filtration efficiency, and existing filter cartridge structures are not convenient or efficient enough for cleaning dust or removing impurities.

[0003] To address the aforementioned problems, some improvements have been proposed in the prior art, such as setting a detachable connection structure for easy disassembly and installation, or setting a dust removal device to clean impurities on the filter layer. However, in these solutions, the various functional structures often operate independently, lacking effective mechanical linkage, resulting in an inconvenient operation process and requiring improvement in the overall structural coordination and practicality. Therefore, this application proposes an improved metal filter cartridge structure based on the prior art to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a metal filter cartridge structure that can solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal filter cartridge structure, comprising connecting sleeves coaxially rotatably connected to the upper and lower ends of the filter cartridge body, a filter screen coaxially fixedly connected inside the filter cartridge body, an internal thread formed inside the connecting sleeve, and a telescopic sleeve with an external thread coaxially disposed inside the connecting sleeve, the outer wall of the telescopic sleeve being threadedly connected to the inner wall of the connecting sleeve, the upper and lower telescopic sleeves being symmetrically arranged, and sliding components being provided at the front and rear ends of the telescopic sleeves respectively, which are slidably connected to the outer side wall of the filter cartridge body, a driving mechanism being fixedly installed on the left side wall of the filter cartridge body, the driving mechanism being connected to the connecting sleeves through transmission components, a connecting rod being fixedly connected to the inner wall of the connecting sleeve, a vertical rod being fixedly connected to the middle of the connecting rod, and a scraper being fixedly connected to the end of the vertical rod, the scraper abutting against the surface of the filter screen.

[0006] Preferably, the drive mechanism includes a dual-axis motor fixedly installed on the left side wall of the filter cartridge body, and the upper and lower drive shafts of the dual-axis motor are respectively connected to the transmission assembly.

[0007] Preferably, the transmission assembly includes two rotating shafts arranged symmetrically at the top and bottom. The two rotating shafts are coaxially and fixedly connected to the upper and lower drive shafts of the drive motor, respectively. Transmission gears are coaxially and fixedly mounted on the rotating shafts. External gear rings are coaxially and fixedly connected to the opposite ends of the two connecting sleeves, respectively. The transmission gears mesh with the external gear rings for transmission.

[0008] Preferably, the sliding assembly includes sliding rods fixedly connected to the front and rear ends of the telescopic sleeve, vertical sliding grooves are respectively opened on the front and rear side walls of the filter cartridge body, and a slider is fixedly connected to the end of the sliding rod, and the slider is slidably connected in the vertical sliding groove.

[0009] Preferably, the outer ends of both telescopic sleeves are coaxially fixedly fitted with tapered sealing sleeves, and the two tapered sealing sleeves are arranged symmetrically above and below.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] After the drive mechanism is started, it drives the two connecting sleeves to rotate through the transmission component. Since the telescopic sleeves are slidably connected to the filter cartridge body through the sliding component, the two telescopic sleeves move away from each other or closer together. When the drive mechanism drives the two telescopic sleeves to move away from each other, the interface between the telescopic sleeves and the external equipment is tightly inserted and fitted to achieve a sealed connection. When the drive mechanism drives the two telescopic sleeves to move closer together, the interface between the telescopic sleeves and the external equipment is disengaged. When the drive mechanism drives the connecting sleeves to rotate, the connecting sleeves drive the connecting rod to rotate, the connecting rod drives the vertical rod to rotate, and the vertical rod drives the scraper to rotate. The scraper scrapes away impurities on the surface of the filter screen to prevent impurities from adhering to and clogging the holes on the filter screen. This utility model facilitates the disassembly and assembly of the filter cartridge body and the external equipment, and also enables the cleaning of impurities on the outer surface of the filter screen during the disassembly and assembly of the filter cartridge body.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a metal filter cartridge structure, including connecting sleeves 2 that are coaxially rotatably connected to the upper and lower ends of the filter cartridge body 1, a filter screen 3 that is coaxially fixedly connected inside the filter cartridge body 1, an internal thread formed inside the connecting sleeve 2, a telescopic sleeve 4 with an external thread that is coaxially provided inside the connecting sleeve 2, the outer wall of the telescopic sleeve 4 being threadedly connected to the inner wall of the connecting sleeve 2, the upper and lower telescopic sleeves 4 being symmetrically arranged, sliding components being provided at the front and rear ends of the telescopic sleeve 4, the sliding components being slidably connected to the outer wall of the filter cartridge body 1, a driving mechanism being fixedly installed on the left side wall of the filter cartridge body 1, the driving mechanism being connected to the connecting sleeve 2 through a transmission component, a connecting rod 5 being fixedly connected to the inner wall of the connecting sleeve 2, a vertical rod 6 being fixedly connected to the middle of the connecting rod 5, a scraper 7 being fixedly connected to the end of the vertical rod 6, and the scraper 7 abutting against the surface of the filter screen 3;

[0019] The working principle of this utility model is as follows: After the drive mechanism is started, it drives the two connecting sleeves 2 to rotate through the transmission component. Since the telescopic sleeve 4 is slidably connected to the filter body 1 through the sliding component, it drives the two telescopic sleeves 4 to move away from each other or closer to each other. When the drive mechanism drives the two telescopic sleeves 4 to move away from each other, the telescopic sleeve 4 is tightly inserted and fitted with the interface of the external equipment to achieve a sealed connection. When the drive mechanism drives the two telescopic sleeves 4 to move closer to each other, the telescopic sleeve 4 is disengaged from the interface of the external equipment. When the drive mechanism drives the connecting sleeve 2 to rotate, the connecting sleeve 2 drives the connecting rod 5 to rotate, the connecting rod 5 drives the vertical rod 6 to rotate, and the vertical rod 6 drives the scraper 7 to rotate. The scraper 7 scrapes away the impurities on the surface of the filter screen 3 to prevent the impurities from adhering and clogging the holes on the filter screen 3. This utility model facilitates the disassembly and assembly of the filter body 1 and the external equipment, and cleans the impurities on the outer surface of the filter screen 3 when disassembling and assembling the filter body 1.

[0020] The driving mechanism of this utility model includes a dual-axis motor 8 fixedly installed on the left side wall of the filter cartridge body 1. The upper and lower drive shafts of the dual-axis motor 8 are respectively connected to a transmission assembly. The transmission assembly includes two rotating shafts 9 symmetrically arranged vertically. The two rotating shafts 9 are coaxially fixedly connected to the upper and lower drive shafts of the drive motor 8. A transmission gear 10 is coaxially fixedly mounted on the rotating shaft 9. External gear rings 11 are coaxially fixedly connected to the opposite ends of the two connecting sleeves 2. The transmission gear 10 meshes with the external gear rings 11 for transmission. The sliding assembly includes sliding rods 12 fixedly connected to the front and rear ends of the telescopic sleeve 4, and the front and rear side walls of the filter cartridge body 1. Vertical grooves 13 are provided on each of the two sleeves. A slider 14 is fixedly connected to the end of the sliding rod 12. The slider 14 is slidably connected in the vertical groove 13. This utility model starts the dual-axis motor 8, which drives the two rotating shafts 9 to rotate. The rotating shafts 9 drive the transmission gear 10 to rotate, and the transmission gear 10 drives the external gear ring 11 to rotate, thereby driving the connecting sleeve 2 to rotate. The connecting sleeve 2 is threadedly connected to the telescopic sleeve 4, and the slider 14 on the sliding rod 12 of the telescopic sleeve 4 is slidably connected to the vertical groove 13. Therefore, the rotating connecting sleeve 2 drives the telescopic sleeve 4 to move along its axial direction, thereby realizing the two telescopic sleeves 4 moving closer or further apart.

[0021] Specifically, the outer ends of the two telescopic sleeves 4 are coaxially fixedly fitted with tapered sealing sleeves 15. The two tapered sealing sleeves 15 are arranged symmetrically above and below. By setting tapered sealing sleeves 15, this utility model can be inserted and sealed with the interface of external equipment of different sizes.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
