Description

A circulating filter dryer

Technical Field

The utility model relates to the field of drying filters, in particular to a circulating drying filter.

Background Art

The main function of the dry filter is to filter out impurities; generally speaking, the specifications of the dryer are determined according to the refrigeration system of the refrigerator or air conditioner, such as the diameter, inner diameter, outer diameter, and internal components such as the filter bowl, mesh, and molecular sieve.

The patent number CN217584954U in the prior art discloses a sealed circulation filter dryer for refrigeration equipment, including a filter dryer body, both side walls of the filter dryer body are fixedly installed with sealing covers, and the middle of the side walls of the sealing covers are connected with an air inlet pipe. In the above scheme, the filter dryer is provided with a mounting assembly. When the model of the filter dryer body to be replaced is smaller than the model of the connecting pipe, one end of the air inlet pipe is inserted into the interior of the connecting pipe, and then the telescopic rod inside the mounting assembly is started, and then the telescopic rod will drive the support block to move around the mounting ring until the connecting suction cup on the outer surface of the connecting ring fits with one side of the inner wall of the connecting pipe, so that the filter dryer body is connected to the connecting pipe. Because the connecting suction cup has a certain adsorption force, it can adsorb the connecting pipe, thereby preventing the filter dryer body from separating from the connecting pipe and reducing losses.

However, the patents in the prior art have the following disadvantages: the prior art drying filter is an integral structure, and the air conditioning refrigeration drying filter cannot be quickly disassembled to replace or clean the filter screen and desiccant inside when needed, resulting in economic waste of the drying filter.

The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

As shown in Figures 1 to 6, a circulating drying filter includes a shell 1. There are two shells 1. The shell 1 is a semi-cylindrical shell structure. The two shells 1 are combined and installed into a cylindrical shell structure. Connecting plates 2 are installed at both ends of each shell 1. The two groups of connecting plates 2 are connected by mounting bolts 3. A sealing gasket is installed between the two groups of connecting plates 2 to ensure the sealing of the shell 1. A cover body 4 is installed at both ends of the two shells 1 after splicing. The cover body 4 is clamped to the shell 1. A sealing gasket is installed between the shell 1 and the cover body 4 to ensure the sealing between the cover body 4 and the shell 1.

An inlet pipe 5 is installed at one end of the cover body 4 for introducing refrigerant. A sealing structure 6 is installed on one side of the circumferential surface of the shell 1. There are two sealing structures 6 symmetrically about each shell 1. The sealing structure 6 can improve the sealing between the cover body 4 and the shell 1.

The sealing structure 6 includes a fixed block 9, which is fixedly mounted on the outside of the shell 1. A rotatable screw 10 is installed inside the fixed block 9. A turntable 11 is installed at one end of the screw 10 outside the fixed block 9. The turntable 11 facilitates the rotation of the screw 10. A movable plate 12 is installed on the surface of the screw 10. A slide groove 15 is provided at the inner wall of the fixed block 9. One end of the movable plate 12 slides inside the slide groove 15. The other end of the movable plate 12 is threadedly connected to the screw 10. When the screw 10 rotates, the movable plate 12 moves up and down along the direction of the screw 10 under the restriction of the slide groove 15. A slide rod 13 is installed at one end of the movable plate 12. The slide rod 13 is plugged into the fixed block 9. The slide rod 13 can slide inside the fixed block 9. The movement of the movable plate 12 drives the slide rod 13 to move. A pressing plate 14 is installed at the other end of the slide rod 13, thereby driving the pressing plate 14 to move, so that the pressing plate 14 can be tightly attached to or separated from the cover body 4, which is convenient for the installation and disassembly of the cover body 4 and the shell 1.

An arc groove is provided inside the shell 1, and there are two arc grooves symmetrically about the shell 1. A metal mesh 7 is installed in the arc groove. The metal mesh 7 is disc-shaped. A desiccant is placed between the two metal meshes 7. A cleaning structure 8 is installed at the other end of the metal mesh 7. The cleaning structure 8 can clean the dust on the surface of the metal mesh 7 to prevent the metal mesh 7 from being blocked.

The cleaning structure 8 includes a transverse plate 16, and a motor 18 is installed at one end of the transverse plate 16. The output end of the motor 18 is connected to the transverse plate 16. When the motor 18 is started, it can drive the transverse plate 17 to rotate. Cleaning brushes 19 are installed on both sides of the transverse plate 16 near one end of the motor 18. Cleaning brushes 20 are installed near one end of the shell 1. Dust boxes 21 are installed at both ends of the cleaning brush 19. The cleaning brush 19 is close to the surface of the metal mesh 7, and the cleaning brush 20 is close to the inner wall of the shell 1. When the transverse plate 16 rotates, it drives the cleaning brush 19 to rotate. The cleaning brush 19 cleans the mesh of the metal mesh 7 to prevent the metal mesh 7 from being blocked. The cleaning brush 20 cleans the inner wall of the shell 1, and the cleaned dust is collected by the dust box 21. The shell 1 is regularly disassembled for processing to prevent dust from clogging the metal mesh 7 again.

A slot 22 is installed at one end of the metal mesh 7, and the motor 18 is inserted into the slot 22. A positioning pin 23 is installed at the outer end of the slot 22 to fix the motor 18, thereby fixing the cleaning structure 8.

During specific use, when the metal mesh 7 needs to be cleaned of surface dust, the starting motor 18 drives the horizontal plate 16 to rotate. When the horizontal plate 16 rotates, it drives the cleaning brush 19 to rotate. The cleaning brush 19 cleans the mesh of the metal mesh 7 to prevent the metal mesh 7 from being blocked. The cleaning brush 20 cleans the inner wall of the shell 1. The cleaned dust is collected by the dust box 21. The shell 1 is disassembled regularly for processing to prevent dust from clogging the metal mesh 7 again.

When disassembly and maintenance are required, the turntable is rotated, and the turntable 11 drives the screw 10 to rotate. The movable plate 12 moves up and down along the direction of the screw 10 under the restriction of the slide groove 15, thereby driving the slide bar 13 to slide inside the fixed block 9, thereby driving the pressure plate 14 to move, so that the pressure plate 14 can be separated from the cover body 4, which is convenient for the disassembly of the cover body 4 and the shell 1. After removing the bolts 3, the connecting plate 2 is separated, thereby disassembling the two shells 1, and the parts inside the shell 1 can be replaced and repaired. The cleaning structure 8 can be disassembled for maintenance through the positioning pin 23.

The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
