Description

Technical Field

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

[0002] With the development of refrigeration technology, and as modern refrigeration technology continues to move towards higher efficiency, energy saving, and environmental protection, the requirements for various components of the refrigeration system are also becoming increasingly stringent. For example, there are trends such as the use of new refrigerants and the miniaturization of refrigeration systems. This side-connected dryer filter is used in the pretreatment of the refrigerant.

[0003] However, in actual use, there are still many defects in similar dryer filters. For example, when the internal filter components of the existing dryer need to be maintained (such as replacing the filter element), the entire dryer may need to be disassembled, which is complicated and time-consuming. At the same time, the existing dryer filters may have poor sealing performance, which may lead to refrigerant leakage or fluid short circuit during the filtration process. Therefore, it is necessary to design a dryer filter with a side-connection. Utility Model Content

[0004] To at least partially solve the above-mentioned technical problems, this utility model provides a side-connected drying filter.

[0005] This utility model is achieved using the following technical solution: a side-connected drying filter, comprising a mounting platform assembly, the mounting platform assembly including a filter bottle, a connecting pipe fixedly mounted on the outer surface of the filter bottle, a side-connected pipe threaded to the outer surface of the connecting pipe, and anti-slip blocks evenly distributed around the filter bottle on the outer surface of the filter bottle, further comprising:

[0006] A separation assembly, the separation assembly including a protective cover rotatably mounted on the outer surface of a filter bottle, and a rotating rod fixedly mounted on the bottom of the protective cover;

[0007] A filter assembly includes a mounting sleeve threaded to the outer surface of a rotating rod, a filter seat inserted into the outer surface of the mounting sleeve, and a filter plate fixedly installed inside the filter seat.

[0008] As a further improvement to the above solution, the protective cover is rotatably mounted on the top of the outer surface of the filter bottle, and a vent is provided inside the protective cover.

[0009] Through the above technical solution, the rotating installation method of the protective cover at the top can effectively protect the components inside the filter bottle from the intrusion of external dust, impurities, etc. during normal operation, and the presence of vent holes ensures the normal flow path of fluid inside the filter.

[0010] As a further improvement to the above solution, a base plate is fixedly installed at the bottom of the mounting sleeve, and the interior of the base plate has ventilation holes corresponding to the ventilation holes.

[0011] Through the above technical solution, the corresponding setting of the vent hole ensures the smooth transition of fluid from the protective cover to the filter component, which helps to maintain the continuity of fluid flow in the entire dryer filter, and ensures that the refrigerant and other fluids in the refrigeration system can pass through each component in sequence according to the predetermined path for filtration and drying, thereby improving the working efficiency of the entire refrigeration system and reducing energy loss caused by obstructed fluid flow.

[0012] As a further improvement to the above solution, the outer surface of the base plate is provided with a threaded groove, and the bottom of the inner wall of the filter bottle is provided with a threaded groove that engages with the base plate, and the base plate is threadedly connected to the inside of the filter bottle.

[0013] With the above technical solution, even when faced with fluid flow impacts or system vibrations during the operation of the refrigeration system, the filter components will not easily shift or loosen. This helps to ensure the stability and reliability of the filtration process, ensuring that the filter components can continuously and effectively filter and dry the fluid, and extending the service life of the filter components and the entire dryer filter.

[0014] As a further improvement to the above solution, a fixing seat is fixedly installed on the outer surface of the mounting sleeve, and symmetrical filter seats are inserted into the interior of the fixing seat.

[0015] With the above technical solution, when maintenance of the filter housing is required (such as replacing the filter plate or cleaning the inside of the filter housing), the filter housing can be easily pulled out or inserted from the mounting base. The operation is simple and does not require complicated tools. This greatly reduces maintenance costs and difficulty, improves the maintainability of the dryer filter, and helps maintain the filtration performance of the dryer filter.

[0016] As a further improvement to the above solution, an embedding groove is provided on one side of the outer surface of the filter seat, and an embedding seat is fixedly installed on the other side of the filter seat away from the embedding groove.

[0017] As a further improvement to the above solution, an air inlet is provided at the top of the filter housing, a filter plate is fixedly installed inside the filter housing at the bottom of the air inlet, and an exhaust port is provided at the bottom of the filter plate at the bottom of the filter housing.

[0018] Through the above technical solution, the air inlet can accurately guide the fluid into the filter seat. After being filtered by the filter plate, impurities (such as metal shavings, dust, etc.) are removed, and the clean fluid is discharged from the exhaust port. The filter plate effectively filters impurities, protecting other key components in the refrigeration system (such as the compressor, expansion valve, etc.) from damage by impurities and preventing blockage.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] During normal operation, the protective cover protects the internal structure, preventing external impurities and dust from entering the filter, thus protecting the filter components and other internal parts from contamination and extending their service life. The vent ensures normal fluid flow and the normal operation of the refrigeration system. When maintenance or inspection is required, the protective cover can be easily opened by rotating it, facilitating subsequent replacement and cleaning of the filter base. This design makes operation simple and convenient, without the need for complicated disassembly tools or procedures.

[0021] This invention facilitates the installation and removal of the filter base through the plug-in connection between the fixed base and the filter base. When it is necessary to replace or clean the filter base, the user can easily pull the filter base out of the fixed base or insert it. The operation is simple and quick. The connection between the embedding groove and the embedding base between the filter bases ensures the sealing and integrity between the filter bases. The sealing ensures that the fluid can only flow along the predetermined path, that is, enter from the air inlet, pass through the filter plate and exit from the exhaust port, preventing fluid leakage or short circuit. The integrity ensures the overall structural stability of the filter assembly, which helps to improve the filtration effect and service life. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

[0032] Please combine Figure 1-6 A side-connected drying filter according to this embodiment includes a mounting platform assembly 1, which includes a filter bottle 101. A connecting pipe 102 is fixedly mounted on the outer surface of the filter bottle 101. A side-connecting pipe 103 is threaded onto the outer surface of the connecting pipe 102. Anti-slip blocks 104 are evenly distributed on the outer surface of the filter bottle 101 with the filter bottle 101 as the center. The filter also includes:

[0033] Separation assembly 2 includes a protective cover 201 rotatably mounted on the outer surface of filter bottle 101, and a rotating rod 203 fixedly mounted on the bottom of the protective cover 201;

[0034] The filter assembly 3 includes a mounting sleeve 301 threaded to the outer surface of the rotating rod 203, a filter seat 304 inserted into the outer surface of the mounting sleeve 301, and a filter plate 308 fixedly installed inside the filter seat 304.

[0035] The protective cover 201 is rotatably mounted on the top of the outer surface of the filter bottle 101, and the protective cover 201 has a vent hole 202 inside.

[0036] The bottom of the mounting sleeve 301 is fixedly mounted with a base plate 302, and the interior of the base plate 302 has a vent hole 202 corresponding to the vent hole 202.

[0037] The vent 202 on the base plate 302 corresponds to the vent 202 on the protective cover 201, ensuring that the fluid can pass smoothly through the protective cover 201 into the filter assembly 3.

[0038] The outer surface of the base plate 302 is provided with a threaded groove, and the bottom of the inner wall of the filter bottle 101 is provided with a threaded groove that engages with the base plate 302. The base plate 302 is threadedly connected to the inside of the filter bottle 101.

[0039] A mounting base 303 is fixedly mounted on the outer surface of the mounting sleeve 301, and symmetrical filter seats 304 are inserted into the inside of the mounting base 303.

[0040] An embedding groove 305 is provided on one side of the outer surface of the filter seat 304, and an embedding seat 306 is fixedly installed on the other side of the filter seat 304 away from the embedding groove 305.

[0041] When maintenance or inspection is required, the protective cover 201 can be rotated, and the rotating rod 203 will rotate accordingly. Since the mounting sleeve 301 is threadedly connected to the outer surface of the rotating rod 203, the mounting sleeve 301 will descend when the rotating rod 203 is rotated. As the mounting sleeve 301 descends, the filter assembly 3 can be lowered, making it convenient to replace or clean the filter seat 304 later.

[0042] An air inlet 307 is provided at the top of the filter base 304, and a filter plate 308 is fixedly installed inside the filter base 304 at the bottom of the air inlet 307. An exhaust port 309 is provided at the bottom of the filter plate 308 at the bottom of the filter base 304.

[0043] The filter holder 304 has an air inlet 307 at the top. After the fluid enters the filter holder 304 through the air inlet 307, it first passes through the filter plate 308 fixedly installed inside. The filter plate 308 can filter out impurities in the fluid, such as metal shavings and dust. The fluid filtered by the filter plate 308 is discharged from the exhaust port 309 at the bottom, thereby realizing the function of filtering and purifying the fluid.

[0044] The implementation principle of a side-connected dryer filter in this application embodiment is as follows: Since the connecting pipe 102 and the side-connected pipe 103 are connected by threads, it is convenient for users to install and disassemble, while ensuring the sealing of the connection. In the refrigeration system, the connecting pipe 102 can be used to connect with the main pipe in the system, and the side-connected pipe 103 can be used for some auxiliary connections or connections in special cases such as testing and maintenance. The anti-slip block 104 is evenly distributed on the outer surface of the filter bottle 101, which makes it convenient for users to hold the filter bottle 101 when the protective cover 201 is rotated.

[0045] The protective cover 201 is rotatably mounted on the top of the outer surface of the filter bottle 101. The vent 202 inside is the channel for fluid to enter and exit the separation component 2. During normal operation, the protective cover 201 protects the internal structure, while the vent 202 ensures the normal flow of fluid. When maintenance or inspection is required, the protective cover 201 can be rotated, and the rotating rod 203 will rotate accordingly. Since the mounting sleeve 301 is threadedly connected to the outer surface of the rotating rod 203, the mounting sleeve 301 will descend when the rotating rod 203 rotates. As the mounting sleeve 301 descends, the filter component 3 can be lowered, which facilitates the subsequent replacement or cleaning of the filter seat 304.

[0046] The bottom plate 302 of the mounting sleeve 301 is threadedly connected to the bottom of the inner wall of the filter bottle 101 through a threaded groove. This connection method allows the filter assembly 3 to be securely installed inside the filter bottle 101. At the same time, the vent hole 202 on the bottom plate 302 corresponds to the vent hole 202 on the protective cover 201, ensuring that the fluid can smoothly pass through the protective cover 201 and enter the filter assembly 3. The fixing seat 303 on the outer surface of the mounting sleeve 301 is used to insert the symmetrical filter seats 304. This insertion method facilitates the installation and disassembly of the filter seats 304, making it easy to replace or clean them. The filter seats 304 are connected to each other through the embedding groove 305 on one side and the embedding seat 306 on the other side, ensuring the sealing and integrity between the filter seats 304.

[0047] The filter holder 304 has an air inlet 307 at the top. After the fluid enters the filter holder 304 through the air inlet 307, it first passes through the filter plate 308 fixedly installed inside. The filter plate 308 can filter out impurities in the fluid, such as metal shavings and dust. The fluid filtered by the filter plate 308 is discharged from the exhaust port 309 at the bottom, thereby realizing the function of filtering and purifying the fluid.

[0048] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
