This device can effectively filter impurities in the refrigerant and promptly clean impurities adhering to the inner wall of the filter cartridge, ensuring filtration efficiency. Furthermore, this device has strong structural stability and the filter cartridge is very easy to replace, thereby significantly improving the maintenance efficiency of this device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A filtration mechanism for a gas-liquid separator includes a housing, a cover, and a filter cylinder. The cover is detachably installed at an opening on the top of the housing. An inlet pipe is connected above an inlet in the middle of the cover, and an outlet pipe is connected at an outlet at the bottom of the housing. A first frame is fixedly mounted on the cover below the inlet, and a cleaning assembly is mounted on the frame. The filter cylinder has a mesh structure with an upward-facing opening and is located inside the housing. The top of the filter cylinder abuts against the bottom surface of the cover. The cleaning assembly is located inside the filter cylinder and includes a worm gear and a scraper. The worm gear is horizontally rotatably mounted on the first frame, and a rotating shaft is coaxially fixed below the worm gear. A rotating rod is horizontally fixed on the rotating shaft, and the scraper vertically abuts against the inner wall of the filter cylinder and is fixedly connected to the end of the rotating rod. A second frame is fixedly mounted at the bottom of the housing, and a positioning groove is provided at the top of the second frame. Two positioning plates are fixedly connected to the bottom of the filter cylinder from left to right, and the positioning plates are supported and locked in the positioning groove. A locking assembly is provided in the positioning groove, and the locking assembly is connected to the positioning plates on both sides.

[0006] Preferably, the locking assembly includes a sleeve, a slide rod, a spring, and two transverse blocks. The sleeve is vertically slidably mounted above the slide rod, and the bottom of the slide rod is fixedly connected to the middle of the positioning groove. The spring is mounted outside the slide rod, and its two ends are fixedly connected to the sleeve and the bottom of the positioning groove. The upper end of the sleeve abuts against the bottom of the filter cylinder. The two transverse blocks are slidably mounted on the bottom surface of the positioning groove. The positioning plate has a locking hole, and the outer side of the transverse block is fixedly provided with a locking tongue that cooperates with the locking hole on the corresponding positioning plate. Corresponding connecting rods are provided between the two transverse blocks and the sleeve. One end of the connecting rod is rotatably connected to the side wall of the sleeve, and the other end is inclined downward and rotatably connected to the transverse block.

[0007] Preferably, the lower end of the filter cylinder is provided with a central plate, and the sleeve abuts against the bottom of the central plate.

[0008] Preferably, a rotating block is horizontally rotatably mounted on the upper end of the center plate, and an insertion port is provided on the rotating block, into which the lower end of the rotating shaft is inserted.

[0009] Preferably, the bottom surface of the positioning groove is provided with horizontal sliding grooves on the left and right sides, and the lower part of the transverse plate is slidably engaged in the sliding grooves.

[0010] Preferably, a sealing ring is fixed at the upper opening of the filter cartridge, and the sealing ring abuts against the bottom of the shell cover.

[0011] Preferably, the bottom surface of the shell cover is provided with an annular groove, and the sealing ring is inserted into the annular groove.

[0012] Preferably, the upper opening of the housing and the cover are provided with outwardly protruding flanges, and fixing bolts are provided in the corresponding through holes on the two flanges.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, liquid substances are fed into the housing through the top inlet pipe, and the impurities in the liquid substances are effectively filtered by the filter cylinder before being discharged from the bottom outlet. During this process, when the liquid substances enter from the inlet, they will wash the worm gear and rotate, thereby driving the cleaning component to rotate. The scraper effectively scrapes off the impurities adhering to the inner wall of the filter cylinder, thereby significantly improving the filtration efficiency of this device.

[0015] 2. This application utilizes the through holes in the folded edge with fixing bolts to achieve a quick connection between the cover and the housing, thereby greatly facilitating the maintenance and repair work of this application.

[0016] 3. This application has a rotatable rotating block installed on the center plate at the bottom of the filter cylinder. The lower end of the rotating shaft is inserted into the slot inside the rotating block. When the rotating shaft rotates, the rotating block can rotate synchronously, thereby providing stable support for the lower end of the rotating shaft and significantly improving the operational stability of the cleaning component of this device.

[0017] 4. When the filter cartridge is installed downwards by pressing the cover, the center plate of the filter cartridge will press down on the sleeve and compress the spring. As the sleeve moves downwards, it will push the transverse block outwards via the connecting rods on both sides, causing the locking tongue on the transverse block to engage with the locking holes on the positioning plates on both sides, thus achieving quick fixation of the filter cartridge. When maintenance or replacement of the filter cartridge is required, after opening the cover, the filter cartridge loses downward pressure. Under the action of the spring force, the sleeve and filter cartridge will be pushed upwards, which will then drive the transverse block to move towards the center via the connecting rods, causing the locking tongue to disengage from the locking holes on the positioning plates, achieving quick disassembly of the filter cartridge, which is very convenient to use.

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0021] like Figure 1-2 As shown, this utility model proposes a filtration mechanism for a gas-liquid separator, including a housing 1, a cover 12, and a filter cylinder 2. The cover 12 is detachably installed at the opening at the top of the housing 1. An inlet pipe 13 is connected above the liquid inlet 130 in the middle of the cover 12, and an outlet pipe 11 is connected at the liquid outlet 110 at the bottom of the housing 1. Both the upper opening of the housing 1 and the cover 12 have horizontally protruding flanges 14, and fixing bolts 15 are installed in corresponding through holes on the two flanges 14. This application utilizes the fixing bolts 15 passing through the through holes on the flanges 14 to achieve a quick connection between the cover 12 and the housing 1, thereby greatly facilitating the maintenance and repair work of this application.

[0022] A first frame 122 is fixedly mounted on the cover 12 below the liquid inlet 130. A cleaning component is installed on the first frame 122 and is located inside the filter cartridge 2. The filter cartridge 2 has a mesh structure and an upward-facing opening. The filter cartridge 2 is located inside the housing 1. The top of the filter cartridge 2 abuts against the bottom surface of the cover 12. A sealing ring 21 is fixedly mounted at the upper opening of the filter cartridge 2. An annular groove 121 is provided on the bottom surface of the cover 12, and the sealing ring 21 is inserted into the annular groove 121.

[0023] The sealing ring 21 provided at the upper opening of the filter cartridge 2 of this application cooperates with the annular groove 121 below the cover 12, thereby improving the tightness of the connection between the filter cartridge 2 and the cover 12.

[0024] The cleaning assembly includes a worm gear 31 and a scraper 34. The worm gear is horizontally mounted on the first frame 122. A rotating shaft 32 is coaxially fixed below the worm gear, and a rotating rod 33 is horizontally fixed to the rotating shaft 32. The scraper 34 vertically abuts against the inner wall of the filter cartridge 2 and is fixed to the end of the rotating rod 33. Furthermore, a center plate 22 is provided in the middle of the closed lower end of the filter cartridge 2. A rotating block 221 is horizontally rotatably mounted on the upper end of the center plate 22. A socket 2210 is provided on the rotating block 221, and the lower end of the rotating shaft 32 is inserted into the socket 2210. In specific implementations, the lowermost end of the rotating shaft 32 can be designed as a square or triangular connector, and the socket 2210 can be designed to match it to ensure connection stability.

[0025] The liquid material fed into the housing 1 through the upper inlet 130 impacts the worm gear 31 downwards, causing it to rotate horizontally. This, in turn, drives the rotating shaft 32, rotating rod 33, and scraper 34 to rotate, allowing the scraper 34 to effectively scrape off impurities adhering to the inner wall of the filter cartridge 2, thereby improving the filtration efficiency of the filter cartridge 2. Furthermore, a rotatable rotating block 221 is installed on the central plate 22 at the bottom of the filter cartridge 2. The lower end of the rotating shaft 32 is inserted into the insertion port 2210 of the rotating block 221. When the rotating shaft 32 rotates, the rotating block 221 rotates synchronously, providing stable support for the lower end of the rotating shaft 32 and significantly improving the operational stability of the cleaning components of this device.

[0026] A second frame 16 is fixedly mounted on the bottom of the housing 1. A positioning groove 161 is provided on the top of the second frame 16. Two positioning plates 23 are fixedly connected to the bottom of the filter cylinder 2, one on each side. The positioning plates 23 support and are engaged on the left and right sides of the positioning groove 161, thus effectively restricting and positioning the bottom of the filter cylinder 2. A locking assembly is provided in the positioning groove 161, connected to the positioning plates 23 on both sides. The locking assembly includes a sleeve 41, a sliding rod 43, a spring 42, and two transverse blocks 45. The sleeve 41 is vertically slidably mounted above the sliding rod 43. The bottom of the sliding rod 43 is fixedly connected to the middle of the positioning groove 161. The spring 42 is mounted outside the sliding rod 43, and its two ends are fixedly connected to the sleeve 41 and the bottom of the positioning groove 161. The upper end of the sleeve 41 abuts against the bottom of the center plate 22. A horizontal sliding groove 162 is provided on the bottom surface of the positioning groove 161. The lower part of the transverse blocks is slidably engaged in the sliding groove 162, thereby improving the stability of the two transverse blocks when moving left and right.

[0027] The positioning plate 23 has a lock hole 230. The outer side of the transverse block 45 is fixed with a lock tongue 451 that cooperates with the lock hole 230 on the corresponding positioning plate 23. The two transverse blocks 45 and the sleeve 41 are respectively provided with corresponding connecting rods 44. One end of the connecting rod 44 is rotatably connected to the side wall of the sleeve 41, and the other end is inclined downward and rotatably connected to the transverse block 45.

[0028] When the cover 12 of this application presses the filter cylinder 2 downwards for installation, the center plate 22 of the filter cylinder 2 will press down on the sleeve 41 and compress the spring 42. As the sleeve 41 moves downwards, it will push the transverse block 45 outwards through the connecting rods 44 on both sides, so that the locking tongue 451 on the transverse block 45 will engage in the locking hole 230 on the positioning plates 23 on both sides, thereby achieving quick fixation of the filter cylinder 2. When the filter cylinder 2 needs to be maintained or replaced, after opening the cover 12, the filter cylinder 2 loses the downward pressure. Under the elastic force of the spring 42, the sleeve 41 and the filter cylinder 2 will be pushed upwards, and then the connecting rod 44 will drive the transverse block 45 to move towards the center, so that the locking tongue 451 disengages from the locking hole 230 on the positioning plate 23, achieving quick disassembly of the filter cylinder 2, which is very convenient to use.

[0029] When using this invention, the refrigerant liquid phase substance is sent into the housing 1 through the liquid inlet pipe 13 at the top. The impurities in the liquid phase substance are effectively filtered by the filter cylinder 2 and then discharged from the liquid outlet 110 at the bottom. During this process, when the liquid phase substance enters from the liquid inlet 130, it will wash the worm gear 31 to rotate, thereby driving the cleaning component to rotate. The scraper 34 is used to effectively scrape off the impurities adhering to the inner wall of the filter cylinder 2, thereby significantly improving the filtration efficiency of this device.
