Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a dryer filter assembly and refrigeration equipment. Background Technology

[0002] Patent publication number CN218993751U discloses a dryer filter assembly and a refrigeration device. The weld joint connecting the connecting pipe and the dryer filter is located within a receiving cavity, as is the weld joint connecting the capillary tube and the dryer filter. When the connecting pipe, capillary tube, or dryer filter vibrates, the outer shell causes the weld joints and other components to vibrate at the same frequency, making the weld joints less prone to breakage due to stress. The dryer filter assembly provided in this application has a stable structure, which to some extent extends the service life of the dryer filter assembly.

[0003] During use, excessive moisture in the refrigeration system can lead to excessively high humidity inside the dryer filter assembly. As a result, the desiccant inside the dryer filter will absorb too much moisture and clump together, which will reduce its moisture absorption performance.

[0004] Furthermore, the clumping of the desiccant reduces its contact area with the refrigerant, making it unable to effectively remove moisture from the refrigerant. As the system operating temperature gradually decreases, when the temperature drops below the freezing point, this moisture will condense into ice, clogging the pipes or filters in the system, forming ice blockage, and affecting the normal operation of the refrigeration system. Utility Model Content

[0005] In view of the problem that the excessive humidity inside the above-mentioned dryer filter causes the desiccant to clump, reduces its moisture absorption performance, and causes pipe blockage, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a drying filter assembly, including a body, the body being composed of an upper shell and a lower shell, and a filter chamber disposed within the body;

[0007] An inlet pipe is provided at the end of the upper housing away from the lower housing, and the inlet pipe is connected to the inside of the filter chamber. A water absorption component is provided at the end of the filter chamber near the lower housing for water removal. A drive component is provided at the end of the filter chamber near the upper housing for improving the water absorption performance of the water absorption component.

[0008] The drive assembly includes a main shaft, a flow guide portion disposed at one end of the main shaft near the upper housing, a drive wheel disposed at one end of the main shaft near the flow guide portion, and an agitator wheel disposed at one end of the main shaft away from the flow guide portion.

[0009] In a preferred embodiment of the dryer filter assembly of this utility model, the water absorption assembly includes a storage shell and a baffle plate disposed at the opening of the storage shell. The storage shell and the baffle plate form a water removal chamber, in which a desiccant is disposed. A rotating groove is disposed in the middle region of the bottom of the storage shell, and the end of the main shaft away from the guide portion is rotatably mounted in the rotating groove.

[0010] In a preferred embodiment of the dryer filter assembly of this utility model, the liquid inlet pipe includes a pressure pipe, one end of which is connected to the upper housing, a connecting pipe located at the end of the pressure pipe away from the upper housing, and an acceleration section located at the connection between the pressure pipe and the connecting pipe. The liquid flow area inside the pressure pipe is smaller than the liquid flow area inside the connecting pipe.

[0011] As a preferred embodiment of the dryer filter assembly of this utility model, the flow guide is disposed inside the end of the pressure pipe away from the connecting pipe, a plurality of flow guide grooves are disposed outside the flow guide, a plurality of blades are disposed outside the drive wheel, and the plurality of blades have a wavy structure, with gaps between adjacent blades, and the flow guide grooves and the gaps are positioned corresponding to each other.

[0012] In a preferred embodiment of the dryer filter assembly of this utility model, the stirring wheel is disposed in the dewatering chamber, and stirring rods are arranged in an array on the outer side of the stirring wheel. The stirring rods have a V-shaped structure, and discharge grooves are provided on both sides of the stirring rods.

[0013] In a preferred embodiment of the dryer filter assembly of this utility model, a first filter screen is disposed on the main shaft, the first filter screen being located between the drive wheel and the water absorption assembly; and a second filter screen is disposed on the main shaft, the second filter screen being located between the first filter screen and the water absorption assembly.

[0014] As a preferred embodiment of the refrigeration equipment of the dryer filter assembly of the present invention, it includes a refrigeration equipment body, and the dryer filter assembly is disposed within the refrigeration equipment body.

[0015] The beneficial effects of this utility model are:

[0016] 1. The refrigerant circulates within the refrigeration system, driving the drive components to operate. This causes the main shaft to drive the stirring wheel, which, in conjunction with the stirring rod and the discharge trough, stirs the desiccant inside the water absorption assembly. This prevents excessive humidity from causing the desiccant to clump, ensuring its moisture absorption performance. At the same time, the stirring rod agitates the desiccant, increasing the contact area and contact time between the desiccant and the refrigerant, improving the moisture filtration effect of the dryer filter. This prevents moisture from condensing into ice and clogging the pipes or filters in the system, ensuring the normal operation of the refrigeration system.

[0017] 2. The refrigerant circulation drives the drive wheel to rotate, and the wave-like structure of the blades agitates the refrigerant inside the dryer filter, increasing the refrigerant flow rate in the dryer filter and thus improving the refrigerant circulation speed in the refrigeration system, thereby enhancing the refrigeration effect of the refrigeration equipment.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] Reference Figure 2-7 This is the first embodiment of the present invention, which provides a drying filter assembly. The drying filter assembly includes a body, which is composed of an upper shell 1 and a lower shell 11. A water outlet pipe is connected to the end of the lower shell 1 away from the upper shell 1. A connecting flange is provided at the opening of both the upper shell 1 and the lower shell 11. A filter chamber 12 is provided inside the body. The upper shell 1 and the lower shell 11 are connected by bolts. When the moisture absorption performance of the desiccant fails, the drying filter assembly can be quickly disassembled and replaced with a new desiccant by rotating the bolts.

[0035] The liquid inlet pipe 2 is located at the end of the upper housing 1 away from the lower housing 11 and is connected to the inside of the filter chamber 12. The water absorption component 3 is located at the end of the filter chamber 12 near the lower housing 11 for removing water. The driving component 4 is located at the end of the filter chamber 12 near the upper housing 1 for improving the water absorption performance of the water absorption component 3.

[0036] The drive assembly 4 includes a main shaft 41. A guide section 42 is provided at one end of the main shaft 41 near the upper housing 1. A drive wheel 43 is fixedly installed at one end of the main shaft 41 near the guide section 42. An agitator wheel 44 is fixedly installed at one end of the main shaft 41 away from the guide section 42.

[0037] The water absorption assembly 3 includes a storage shell 31 and a baffle plate 32 disposed at the opening of the storage shell 31. The storage shell 31 and the baffle plate 32 form a water removal chamber. A desiccant is disposed in the water removal chamber. The desiccant is preferably a molecular sieve desiccant. A rotating groove is disposed in the middle area of ​​the bottom of the storage shell 31. The end of the main shaft 41 away from the guide part 42 is rotatably installed in the rotating groove. Both the bottom of the storage shell 31 and the baffle plate 32 are provided with through holes. The diameter of the through holes is smaller than the diameter of the molecular sieve particles to prevent the molecular sieve particles from rolling out through the through holes.

[0038] The liquid inlet pipe 2 includes a pressure pipe 21, one end of which is connected to the upper housing 1. A connecting pipe 22 is located at the end of the pressure pipe 21 away from the upper housing 1. An acceleration part 23 is located at the connection between the pressure pipe 21 and the connecting pipe 22. The liquid flow area inside the pressure pipe 21 is smaller than the liquid flow area inside the connecting pipe 22. By reducing the flow area of ​​the refrigerant in the liquid inlet pipe 2, the flow velocity of the refrigerant in the liquid inlet pipe 2 is increased, thereby energizing and rotating the drive wheel 43.

[0039] The flow guide 42 is located inside the pressure pipe 21 at the end away from the connecting pipe 22. Several flow guide grooves 421 are located on the outside of the flow guide 42, and several blades 431 are located on the outside of the drive wheel 43. The blades 431 have a wave-like structure and there are gaps between adjacent blades 431. The flow guide grooves 421 correspond to the gaps. The refrigerant enters the gaps between adjacent blades 431 through the flow guide grooves 421, causing the drive wheel 43 to rotate under the gravity of the refrigerant. At the same time, the wave-like blades 431 also drive the drive wheel 43 to rotate, thereby achieving the purpose of energizing the drive component 4.

[0040] The stirring wheel 44 is located inside the dewatering chamber. Stirring rods 441 are arranged in an array on the outer side of the stirring wheel 44. The stirring rods 441 have a V-shaped structure and discharge troughs 442 are opened on both sides of the stirring rods 441.

[0041] Filter screen 45, made of metal, is mounted on the main shaft 41. It filters out larger solid particles in the refrigerant. Filter screen 45 is located between the drive wheel 43 and the water suction assembly 3. Filter screen 46, made of polyester, is mounted on the main shaft 41. It filters out smaller particles in the refrigerant. Filter screen 46 is located between filter screen 45 and the water suction assembly 3. The cooperation between filter screens 45 and 46 ensures the normal operation of the refrigeration system. At the same time, filter screens 45 and 46 support the main shaft 41, ensuring the normal operation of the drive assembly 4.

[0042] During use, when the refrigerant enters through the connecting pipe 22, it passes through the acceleration section 23, which gradually reduces the flow area of ​​the refrigerant, thereby increasing the flow rate of the refrigerant in the liquid inlet pipe 2. Finally, the refrigerant is guided into the pressure pipe 21, and then the refrigerant comes into contact with the guide section 42. The refrigerant is guided by the guide groove 421, so that the refrigerant flows through the gap between adjacent blades 431. The refrigerant's own weight causes the drive wheel 43 to rotate. At the same time, the flow rate accelerates the refrigerant's impact on the wave-shaped blades 431, which energizes the drive wheel 43 and causes it to rotate. Then the refrigerant passes through the filter screen 1 45, which removes larger solid particles in the refrigerant. Then the refrigerant passes through the filter screen 2 46, which removes smaller solid particles in the refrigerant. Finally, the refrigerant passes through the through hole of the baffle plate 32 and enters the dewatering chamber.

[0043] Meanwhile, as the refrigerant continues to circulate, the drive wheel 43 drives the main shaft 41 to rotate, which in turn energizes the stirring wheel 44. This causes several stirring rods 441 to agitate the molecular sieve in the dehydration chamber, preventing excessive moisture in the refrigerant from causing the molecular sieve particles to clump together. The discharge trough 442 is used to avoid clogging the molecular sieve particles, preventing the desiccant from becoming blocked during the stirring process. This increases the contact area and contact time between the molecular sieve particles and the refrigerant, allowing moisture and particulate impurities in the refrigerant to be filtered out, ensuring the stable operation of the refrigeration equipment. Finally, the refrigerant flows out through the water outlet pipe and enters the next stage.
