Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a filter with corrosion resistance. Background Technology

[0002] Filters primarily function to remove impurities. Generally, the specifications of the filter, such as its diameter, inner diameter, outer diameter, and internal components like the filter bowl, mesh, and molecular sieve, are determined by the refrigeration system of the refrigerator or air conditioner. When the working environment is humid, the filter surface can corrode, affecting its lifespan. Therefore, a corrosion-resistant filter is required.

[0003] A corrosion-resistant dryer filter disclosed in publication number CN220818150U includes a copper shell. A mounting frame is welded to the top surface of the copper shell, and a cover plate is threadedly connected to the top surface of the mounting frame. A drying component is fixedly connected to the center of the top surface of the cover plate. Observation windows are provided on both sides of the top surface of the cover plate. A molecular sieve filter element is fixedly connected to the bottom surface of the cover plate. A coarse metal mesh is fixedly connected to one side of the molecular sieve filter element, and a fine metal mesh is fixedly connected to the other side. This corrosion-resistant dryer filter, through the inclusion of an acid-alkali resistant coating and a drying component, enhances the corrosion resistance of the copper shell. By opening the breathable cloth and placing a desiccant pack inside the breathable mesh, and then covering it with the breathable cloth, the desiccant pack absorbs moisture from the surrounding area of ​​the dryer filter, thus drying the surrounding environment and slowing down the oxidation and corrosion process.

[0004] However, this type of corrosion-resistant filter has the following disadvantages: When internal parts of the filter are damaged, the filter needs to be disassembled. Most existing filters are fixed with bolts, which makes disassembly and cleaning inconvenient. During the use of the filter, excessively large foreign objects can easily clog it, making subsequent cleaning inconvenient. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a highly practical, simple, and corrosion-resistant filter that can be operated easily. This solves the problems mentioned in the background art, such as the need to disassemble the filter when internal parts are damaged, the inconvenience of disassembly and cleaning caused by bolt fixing, and the inconvenience of cleaning the filter due to large foreign objects clogging it during use.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a corrosion-resistant filter, comprising a filter, a sealing cover fixedly installed on the top of the filter, a guide tube fixedly installed in the middle of the surface of the sealing cover, positioning components fixedly installed at the four corners of the surface of the filter, guide plates fixedly installed on both sides inside the filter, and filter components slidably connected to the surface of the guide plates.

[0007] Optionally, the positioning assembly includes positioning plates fixedly installed at the four corners of the filter surface, a rotating rod rotatably connected between the positioning plates, a rotating plate fixedly installed on the surface of the rotating rod, a threaded groove on the surface of the rotating plate, a threaded rod threadedly connected inside the threaded groove, and a clamping plate rotatably connected to one end of the threaded rod.

[0008] Optionally, the positioning plates are provided with rotating grooves on their inner sides, the size of which is adapted to the size of the rotating rod, and the rotating rod rotates inside the rotating groove.

[0009] Optionally, the filter assembly includes a filter plate slidably connected to the surface of the guide plate, with support rods fixedly installed on both sides of the filter plate surface, springs fixedly installed on the surface of the support rods, and an installation cover fixedly installed on the top of the springs, with absorbent cotton provided inside the installation cover.

[0010] Optionally, the surface of the absorbent cotton is provided with several through grooves, and the absorbent cotton is in contact with the interior of the spring.

[0011] Optionally, guide grooves are provided on both sides of the surface of the filter plate, and the size of the guide grooves is adapted to the size of the guide plate, so that the filter plate can slide up and down on the surface of the guide plate.

[0012] This utility model provides a corrosion-resistant filter with the following beneficial effects: 1. This corrosion-resistant filter, through the arrangement of the filter, sealing cap, and positioning component, allows for easy installation. During use, the operator snaps the sealing cap onto the top of the filter and then installs it using the positioning component. After installation, the operator guides the air to be filtered into the interior of the guide tube, thus improving the efficiency of the sealing cap installation.

[0013] 2. This corrosion-resistant filter, through the setting of the guide plate and filter assembly, allows personnel to install the filter assembly via the guide plate during use. After installation, the filter assembly will filter the air, improving the efficiency of air filtration. Attached Figure Description
