[0001] This utility model belongs to the field of refrigerated air dryer technology, and in particular relates to an air filtration structure for a refrigerated air dryer. Background Technology
[0002] A refrigerated air dryer, also known as a freeze dryer, mainly consists of a refrigeration system, an air heat exchange system, a gas-liquid separation system, and an electrical control system. Its working principle is to use the refrigeration system to cool the high-temperature and high-humidity compressed air to below the dew point temperature, causing the water vapor in the air to condense into liquid water. The liquid water is then separated out by the gas-liquid separation system, thereby achieving the purpose of drying the compressed air.
[0003] The problem with existing technology is that the traditional filter structure used in refrigerated dryers is inconvenient to clean. Over time, the filter structure will accumulate a lot of impurities, resulting in low efficiency. Therefore, the traditional device can no longer meet people's daily work needs. So we propose an air filtration structure for refrigerated dryers. Utility Model Content

The installation assembly is used for installing and fixing the filter assembly, and the filter assembly is used for filtering impurities in the air.
[0006] As a preferred embodiment of the present invention, the mounting assembly includes a fixing ring, which is fixedly connected to the surface of the air intake pipe, and mounting blocks are fixedly connected to three sides of the surface of the fixing ring.
[0007] As a preferred embodiment of this utility model, each of the three sets of mounting blocks is fixedly connected with a rotating rod, and each of the three sets of rotating rods is fitted with a torsion spring.
[0008] As a preferred embodiment of this utility model, each of the three sets of torsion springs has an arc-shaped plate fixedly connected to its surface, and each of the three sets of arc-shaped plates has a positioning block fixedly connected to one side of its surface.
[0009] As a preferred embodiment of this utility model, each of the three sets of positioning blocks has a positioning plate detachably connected to its surface, and each of the three sets of positioning plates has a connecting plate fixedly connected to one end of its surface.
[0010] As a preferred embodiment of the present invention, the filter assembly includes a central shell, which is fixedly connected to one side of the connecting plate surface. The central shell is disposed inside the air inlet pipe, and four sets of sliding rods are fixedly connected to the inner wall of the central shell.
[0011] As a preferred embodiment of this utility model, all four sets of sliding rods are movably connected to a sliding shell, and a filter plate is fixedly connected to one end of the inner wall of the sliding shell. The filter plate is used to filter dust and impurities in the air, and a pull rod is fixedly connected to the middle of one side of the surface of the filter plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, through the design of the main body of the refrigerated dryer, the air inlet pipe, the mounting component, the filter component and the support legs, allows the filter component to be installed and fixed inside the air inlet pipe using the mounting component during use.

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] like Figures 1 to 3 As shown in the figure, the air filtration structure of a refrigerated dryer provided in this embodiment of the utility model includes a refrigerated dryer body 1, with support legs 5 fixedly connected to the four corners of the lower surface of the refrigerated dryer body 1, an air inlet pipe 2 fixedly connected to one side of the surface of the refrigerated dryer body 1, an installation component 3 provided on the surface of the air inlet pipe 2, and a filter component 4 provided inside the installation component 3. The installation component 3 is used for installing and fixing the filter component 4, and the filter component 4 is used for filtering impurities in the air.
[0023] The above solution is adopted: through the design of the main body 1 of the refrigerated dryer, the air inlet pipe 2, the mounting component 3, the filter component 4 and the support leg 5, the filter component 4 is installed and fixed inside the air inlet pipe 2 by the mounting component 3 during use. At the same time, the filter component 4 can filter impurities in the air and also facilitate the cleaning of the surface of the filter component 4, thereby improving the practicality of the filter component 4.
[0024] refer to Figure 2 The mounting component 3 includes a retaining ring 301, which is fixedly connected to the surface of the intake pipe 2. Mounting blocks 302 are fixedly connected to three sides of the surface of the retaining ring 301. Rotating rods 303 are fixedly connected inside the three sets of mounting blocks 302. Torsion springs 304 are sleeved on the surface of the three sets of rotating rods 303. Arc plates 305 are fixedly connected to the surface of the three sets of torsion springs 304. Positioning blocks 308 are fixedly connected to one side of the surface of the three sets of arc plates 305. Positioning plates 306 are detachably connected to the surface of the three sets of positioning blocks 308. A connecting plate 307 is fixedly connected to one end of the surface of the three sets of positioning plates 306.
[0025] The above solution, through the design of the fixing ring 301, mounting block 302, rotating rod 303, torsion spring 304, arc plate 305, positioning plate 306, connecting plate 307 and positioning block 308, allows the three sets of positioning plates 306 to be attached to the surface of the fixing ring 301 and rotated during use. During the rotation, the positioning plate 306 will push the positioning block 308 to rotate on the surface of the torsion spring 304. When the positioning plate 306 moves to the appropriate position, the torsion spring 304 will drive the arc plate 305 and the positioning block 308 to reset and lock into the inside of the positioning plate 306, thereby completing the installation and fixing of the filter assembly 4 and achieving the effect of facilitating quick assembly and disassembly of the filter assembly 4.
[0026] refer to Figure 3 The filter assembly 4 includes a central shell 401, which is fixedly connected to one side of the connecting plate 307. The central shell 401 is located inside the air intake pipe 2. Four sets of sliding rods 402 are fixedly connected to the inner wall of the central shell 401. A sliding shell 403 is movably connected to each of the four sets of sliding rods 402. A filter plate 404 is fixedly connected to one end of the inner wall of the sliding shell 403. The filter plate 404 is used to filter dust and impurities in the air. A pull rod 405 is fixedly connected to the middle of one side of the surface of the filter plate 404.
[0027] The above solution, through the design of the central shell 401, sliding rod 402, sliding shell 403, filter plate 404 and pull rod 405, when the filter plate 404 has a lot of dust and impurities adhering to its surface during use, pulling the pull rod 405 will pull the sliding shell 403 to move outward using the sliding rod 402, thereby moving the filter plate 404 out, and finally cleaning the filter plate 404, thus achieving the effect of preventing excessive dust and impurities from clogging the filter plate 404.
[0028] The working principle of this utility model:
[0029] In use, the three sets of positioning plates 306 are attached to the surface of the fixing ring 301 and then rotated. During the rotation, the positioning plates 306 will push the positioning blocks 308 to rotate on the surface of the torsion spring 304. When the positioning plates 306 move to the appropriate position, the torsion spring 304 will drive the arc plate 305 and the positioning blocks 308 to reset and lock into the inside of the positioning plates 306, thereby completing the installation and fixing of the filter assembly 4, which facilitates quick assembly and disassembly of the filter assembly 4. When the filter plate 404 has a lot of dust and impurities on its surface during use, pull the pull rod 405. The pull rod 405 will pull the sliding shell 403 and move it outward using the sliding rod 402, thereby moving the filter plate 404 out. Finally, the filter plate 404 is cleaned to prevent excessive dust and impurities from clogging the filter plate 404.
[0030] In summary, this air filtration structure for a refrigerated dryer, through the structure of a central shell 401, a sliding rod 402, a sliding housing 403, a filter plate 404, and a pull rod 405, solves the problem that traditional filtration structures used in refrigerated dryers are inconvenient to clean, and over time, the filter structure accumulates a lot of impurities, resulting in low efficiency. Therefore, traditional devices can no longer meet people's daily work needs.
