Description

Technical Field

[0001] The utility model relates to the technical field of liquid accumulators, in particular to a liquid accumulator for a compressor. Background Art

[0002] The compressor is often connected to a liquid accumulator, which is an important component of the compressor. It is connected and installed between the air-conditioning evaporator and the compressor suction pipe. It plays the role of storage, gas-liquid separation, filtering, silencing and refrigerant buffering. It is a protective component that prevents liquid refrigerant from flowing into the compressor and causing liquid hammer.

[0003] Publication number "CN218583494U" provides a welding structure and a liquid reservoir, which include a first connection part and a second connection part, one end of the second connection part is inserted into the inner side of the first connection part, and the second connection part is provided with an annular protrusion protruding along its own radial direction, and the annular protrusion, the side wall of the second connection part and the end of the first connection part close to the annular protrusion are surrounded to form a receiving groove. This patented technology can stop impurities in the fluid medium on the side of the filter screen close to the air inlet pipe through the filtering effect of the filter screen. Thereby reducing the content of impurities in the fluid medium after gas-liquid separation. In addition, after filtering through the filter screen, the flow rate of the fluid medium is greatly reduced, thereby preventing the fluid medium from impacting the liquid inlet end of the outlet pipe.

[0004] However, the above device still has the following problems during implementation:

[0005] For example, although this patent filters impurities in the fluid through a filter, during the long-term use of the filter, the impurities will be adsorbed on the surface of the filter, causing the gaps inside the filter to be blocked, thereby affecting the amount of fluid passing through. At the same time, it is inconvenient to disassemble and clean the filter, which gradually reduces the use effect of the equipment and affects the service life of the equipment. Utility Model Content

[0006] The purpose of the utility model is to provide a liquid accumulator for a compressor to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] For example, see Figure 1-4 The utility model provides a liquid accumulator for a compressor, comprising a shell 1, a rotating groove 2 is opened on the inner wall of the shell 1, and a first filter screen 3 is fixedly connected to the inner wall of the shell 1, a rotating ring 4 is rotatably connected to the top center of the first filter screen 3, a connecting rod 5 is fixedly connected to the top of the rotating ring 4, and a fan blade 6 is fixedly connected to the top of the connecting rod 5, and an air intake pipe 7 is fixedly connected to the top of the shell 1, and the bottom of the air intake pipe 7 corresponds to the top of the fan blade 6;

[0025] Furthermore, the bottom of the rotating ring 4 is attached to the top of the first filter screen 3, and the outer end of the rotating ring 4 is attached to and slides on the inner wall of the rotating groove 2, the inner wall of the rotating groove 2 is provided with a through hole, and the rotating groove 2 is connected to the storage groove 802;

[0026] More specifically, in this embodiment, when the device is used, the fluid enters the interior of the housing 1 from the air inlet pipe 7 and falls on the surface of the fan blade 6 corresponding to the lower side. Since the blades of the fan blade 6 are arranged in an inclined shape, when the fluid falls on the surface of the fan blade 6, the fan blade 6 will rotate counterclockwise, thereby driving the connecting rod 5 to rotate. At this time, the first filter screen 3 will filter the fluid, so that impurities in the fluid will remain on the surface of the first filter screen 3, and the rotating ring 4 will rotate synchronously with the connecting rod 5, so that the impurities will enter the rotating groove 2 along the side wall of the rotating ring 4 due to the centrifugal force generated by the rotation, and as the rotating ring 4 continues to rotate, the impurities will enter the storage tank 802 through the through hole, thereby completing the collection of the impurities remaining on the surface of the first filter screen 3;

[0027] Then the fluid passing through the first filter screen 3 will enter the liquid storage chamber. By setting the surface of the shielding cover 11 to be inclined, it can play a role in downward drainage. The fluid will fall into the bottom of the liquid storage chamber along the inclined surface of the shielding cover 11 to prevent the fluid from directly entering the air outlet pipe 9. The second filter screen 10 will filter the fluid entering the air outlet pipe 9 to achieve gas-liquid separation and prevent liquid from entering the air outlet pipe 9, causing liquid hammer to damage the compressor.

[0028] Embodiment 2:

[0029] On the basis of the above embodiment, a cleaning mechanism 8 is provided on the outer wall of the housing 1;

[0030] Further, the cleaning mechanism 8 includes a storage box 801, a storage slot 802 is provided inside the storage box 801, a push rod 803 is slidably connected to the top of the storage box 801, and a push plate 804 is fixedly connected to the bottom of the push rod 803, a pressure ring 805 is fixedly connected to the top of the push rod 803, and a spring 806 is fixedly connected to the bottom of the pressure ring 805, the bottom of the spring 806 is fixedly connected to the top of the storage box 801, a sealing cover 807 is hinged to the bottom of the storage box 801, and a pull ring 808 is fixedly connected to the bottom of the sealing cover 807;

[0031] More specifically, in this embodiment, when it is necessary to clean the impurities collected in the storage tank 802, the sealing cover 807 hinged on the bottom of the storage box 801 can be opened by pulling the pull ring 808 to allow the impurities to flow out, and then the pressure ring 805 can be pushed to make the push plate 804 slide downward, so that the impurities remaining on the inner wall of the storage tank 802 can be scraped off. After cleaning, the push plate 804 can be restored by the spring 806 after loosening the pressure ring 805, and finally the sealing cover 807 is closed, thereby finally achieving the cleaning of impurities without disassembling the equipment, thereby improving the efficiency and convenience of use.

[0032] Working principle: When the device is in use, the fluid enters the housing 1 from the air inlet pipe 7 and falls on the surface of the corresponding blade 6 below, causing the blade 6 to rotate counterclockwise. At this time, the first filter screen 3 will filter the fluid, and the connecting rod 5 will rotate synchronously with the blade 6, so that the impurities enter the rotating groove 2 due to the centrifugal force generated by the rotation, and as the rotating ring 4 continues to rotate, the impurities will enter the storage groove 802 through the through hole;

[0033] Then the fluid passing through the first filter screen 3 will enter the liquid storage chamber. By setting the surface of the shielding cover 11 to be inclined, it can play a role in downward drainage. The fluid will fall into the bottom of the liquid storage chamber along the inclined surface of the shielding cover 11 to prevent the fluid from directly entering the air outlet pipe 9. The second filter screen 10 will filter the fluid entering the air outlet pipe 9 to achieve gas-liquid separation and prevent liquid from entering the air outlet pipe 9, causing liquid hammer to damage the compressor.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
