Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separator technology, specifically to a filter element anti-loosening device for a gas-liquid separator. Background Technology

[0002] The gas-liquid separator uses the principles of centrifugal separation and filter cartridge filtration to remove some of the moisture from the air, thereby reducing the workload of the drying device.

[0003] In the prior art, when installing filter elements, some filter element top covers have a flat structure with a single fixing design, resulting in a single fixing force for the filter element. At the same time, under vibration or liquid impact environment, the filter element lacks support and vibration buffer, which can easily cause the fixing device (such as buckle, clamp) of the filter element to loosen, leading to the displacement or falling off of the filter element, thereby affecting the filtration effect on the media.

[0004] Therefore, there is an urgent need for a filter element anti-loosening device for gas-liquid separators to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a filter cartridge anti-loosening device for a gas-liquid separator, comprising a tank and a filter cartridge disposed in the tank, and further comprising an installation assembly disposed in the tank for installing the filter cartridge;

The circular plate and the mounting ring are located on both sides of the filter cartridge and are connected to the inner wall of the tank body through multiple first strip plates and second strip plates, respectively. The circular plate has threaded holes, and threaded rods are threadedly connected to the threaded holes. One end of the threaded rods is connected to the bottom wall of the filter cartridge. The mounting ring has two staggered longitudinal pressure strips and transverse pressure strips on the side away from the circular plate. The longitudinal pressure strips and transverse pressure strips have pressure holes. A sleeve rod is fixedly connected to the end of the filter cartridge away from the circular plate. The sleeve rod is matched with the two pressure holes. A support assembly for supporting the filter cartridge is provided between the circular plate and the mounting ring.

[0007] Each of the second strip plates is fixedly connected to a screw rod on the side near the longitudinal and transverse pressure strips. A nut is threaded onto the side wall of the screw rod. A washer is provided on the side of each nut near the mounting ring. A fixing sleeve is fixedly connected to the side of the longitudinal and transverse pressure strips near the mounting ring. The fixing sleeve is concentrically arranged with the screw rod.

[0008] The support assembly includes multiple connecting plates disposed between the circular plate and the mounting ring. Each connecting plate has its two ends connected to the circular plate and the mounting ring, respectively. Each connecting plate has a support plate connected to its side near the filter cartridge via a shock-absorbing assembly.

[0009] Each of the aforementioned support plates has an inclined plate fixedly connected to both ends near the circular plate and the mounting ring.

[0010] The damping assembly includes a damping tube fixedly connected to the side of the connecting plate near the support plate, a damping plate slidably connected inside the damping tube, a damping rod fixedly connected to the side of the damping plate away from the connecting plate, the end of the damping rod away from the damping plate being connected to the support plate, a spring fixedly connected to the side of the damping plate away from the damping rod, and the end of the spring away from the damping plate being connected to the bottom wall of the damping tube.

Detailed Implementation

[0020] 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.

[0021] Example 1

[0022] Please see Figures 1-5 The illustrated gas-liquid separator filter element anti-loosening device includes a tank 101 and a filter cartridge 102 disposed in the tank 101, and also includes an installation assembly disposed in the tank 101 for installing the filter cartridge 102.

[0023] The mounting assembly includes a circular plate 201 and a mounting ring 202 fixedly connected to the tank body 101. The circular plate 201 and the mounting ring 202 are located on both sides of the filter cartridge 102, and are respectively connected to the inner wall of the tank body 101 through multiple first strip plates 203 and second strip plates 204. The circular plate 201 has a threaded hole 205, and a threaded rod 206 is threadedly connected to the threaded hole 205. One end of the threaded rod 206 is connected to the bottom wall of the filter cartridge 102. On the side of the mounting ring 202 away from the circular plate 201, there are two staggered longitudinal pressure strips 207 and transverse pressure strips 208. The longitudinal pressure strips 207 and transverse pressure strips 208 have pressure holes. A sleeve rod 209 is fixedly connected to the end of the filter cartridge 102 away from the circular plate 201. The sleeve rod 209 is matched with the two pressure holes. A support assembly for supporting the filter cartridge 102 is provided between the circular plate 201 and the mounting ring 202.

[0024] It should be noted that: by setting up the installation components, the filter cartridge 102 is fixed and bidirectionally limited, while the support components provide support and protection for the filter cartridge 102, thereby improving the multidirectional connection force for fixing the filter cartridge 102. At the same time, the shock-absorbing components provide two layers of shock-absorbing protection for the filter cartridge 102, thereby reducing the vibration of the filter cartridge 102 under liquid impact. Thus, under the multidirectional connection limiting and shock-absorbing protection, the risk of the filter cartridge 102 loosening is reduced, thereby improving the stability of the filter cartridge 102 during installation and use.

[0025] It is worth noting that the specific structure and working principle of the gas-liquid separator are already known to those skilled in the art, and will not be elaborated on here. For reference, please refer to the existing public technologies CN219272515U3, a combined gas-liquid separator, or CN221230187U, a filter element structure for a gas-liquid separator.

[0026] Please see Figures 1-3 In the figure, each of the second strip plates 204 is fixedly connected to a screw 211 on the side near the longitudinal pressure strip 207 and the transverse pressure strip 208. The screw 211 is threaded with a nut on the side wall. Each nut is provided with a washer on the side near the mounting ring 202. The longitudinal pressure strip 207 and the transverse pressure strip 208 are fixedly connected to a fixing sleeve 210 on the side near the mounting ring 202. The fixing sleeve 210 is concentrically arranged with the screw 211.

[0027] It should be noted here that the screw 211 and nut are used to connect and fix the longitudinal pressure strip 207 and the transverse pressure strip 208 to the second strip plate 204.

[0028] Please see Figures 1-3 The support assembly shown in the figure includes multiple connecting plates 301 disposed between the circular plate 201 and the mounting ring 202. The two ends of each connecting plate 301 are connected to the circular plate 201 and the mounting ring 202 respectively. The side of each connecting plate 301 near the filter cartridge 102 is connected to the support plate 302 through a shock-absorbing assembly.

[0029] It should be noted that the support components provide support and protection for the filter cartridge 102.

[0030] Please see Figure 4 and Figure 5 In the figure, each support plate 302 is fixedly connected to an inclined plate 303 at both ends near the circular plate 201 and the mounting ring 202.

[0031] It should be noted here that the inclined plate 303 is used to guide and limit the installation of the filter cartridge 102.

[0032] Working principle: When installing the filter cartridge 102, firstly, the threaded rod 206 at one end of the filter cartridge 102 is threaded onto the threaded hole 205 of the circular plate 201. Then, the longitudinal pressure strip 207 and the transverse pressure strip 208 are alternately sleeved onto the sleeve rod 209 at one end of the filter cartridge 102. The longitudinal pressure strip 207 and the transverse pressure strip 208 are connected and fixed by the threaded connection between the screw 211 and the nut. Then, through the pressing of the longitudinal pressure strip 207 and the transverse pressure strip 208 and the threaded connection between the threaded rod 206 and the threaded hole 205, a bidirectional limiting effect is formed on the filter cartridge 102, thereby reliably and effectively limiting the displacement of the filter cartridge 102.

[0033] Furthermore, during the installation of the filter cartridge 102, when the filter cartridge 102 is connected to the circular plate 201, the filter cartridge 102 will push each support plate 302 under the pushing force and the guiding action of the inclined plate 303. Under the elastic action of the shock absorption component, each support plate 302 abuts against the surface of the filter cartridge 102, thereby forming a support and protection for the filter cartridge 102.

[0034] Therefore, by setting up the installation components, the filter cartridge 102 is fixed and bidirectionally limited, while the support components provide support and protection for the filter cartridge 102, thereby improving the multidirectional connection force for fixing the filter cartridge 102. At the same time, the shock-absorbing components provide two layers of shock-absorbing protection for the filter cartridge 102, thereby reducing the vibration of the filter cartridge 102 under liquid impact. Thus, under the multidirectional connection limiting and shock-absorbing protection, the risk of the filter cartridge 102 loosening is reduced, thereby improving the stability of the filter cartridge 102 during installation and use.

[0035] Example 2

[0036] Please see Figure 5 This embodiment further illustrates Example 1. The damping assembly shown in the figure includes a damping tube 401 fixedly connected to the side of the connecting plate 301 near the support plate 302. A damping plate 402 is slidably connected inside the damping tube 401. A damping rod 403 is fixedly connected to the side of the damping plate 402 away from the connecting plate 301. One end of the damping rod 403 away from the damping plate 402 is connected to the support plate 302. A spring 404 is fixedly connected to the side of the damping plate 402 away from the damping rod 403. One end of the spring 404 away from the damping plate 402 is connected to the bottom wall of the damping tube 401. The damping plate 402 has multiple through holes 405 arranged in a ring array. The damping tube 401 is filled with damping fluid, which flows through the through holes 405 when compressed.

[0037] It should be noted that when the filter cartridge 102 is subjected to liquid impact vibration, the vibration force will push the support plate 302 to move, and then the damping rod 403 will push the damping plate 402 to slide inside the damping tube 401. When the damping plate 402 slides, it will compress the spring 404, causing the spring 404 to undergo elastic deformation. The elastic force of the spring 404 will then provide the first layer of shock absorption protection for the filter cartridge 102. At the same time, during the sliding process of the damping plate 402, the damping fluid in the damping tube 401 will be compressed, so that the damping fluid can only pass through the through hole 405, thus forming a damping buffer mechanism, thereby providing the second layer of shock absorption protection for the filter cartridge 102. Therefore, by setting up the shock absorption component, two layers of shock absorption protection are provided for the filter cartridge 102, thereby reducing the vibration of the filter cartridge 102 under liquid impact.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
