Description

Technical Field

[0001] This utility model relates to the technical field of devices for separating or purifying gases or liquids, specifically a detachable dryer filter. Background Technology

[0002] A dryer filter is an important auxiliary component of a refrigeration system. Installed in the piping of an air conditioning refrigeration system, typically between the condenser and the expansion valve, it effectively prevents contaminants from accumulating in one flow direction while absorbing moisture from the refrigerant. The dryer filter employs a combined drying and filtration design, effectively preventing filter media and soluble substances from entering critical components of the refrigeration system, thus ensuring the air conditioning system operates at its optimal condition. Dryer filters play a crucial role in the use of air conditioning refrigeration systems.

[0003] The existing utility model of a dryer filter with publication number CN206399053U has a simple structure, compact design, and is easy to use. The front and rear covers are detachably connected to the cylinder body, which makes it easy to replace the desiccant. The sealing stepped grooves set on the front and rear covers allow the cylinder body to be connected by plugging and unplugging instead of welding during installation, so that the dryer filter can be used repeatedly.

[0004] When the desiccant in the aforementioned utility model fails and needs to be replaced, the operator must first disassemble the entire desiccant filter from the equipment before it can be opened to replace the desiccant. Although this type of desiccant filter saves costs, it adds an extra step of disassembling and reassembling the desiccant filter. Compared to directly replacing the desiccant filter, this method of replacing the desiccant takes longer and thus reduces the efficiency of desiccant replacement. Utility Model Content

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1 to 7This utility model provides a new technical solution: a detachable drying filter, including a fixed outer shell 1, with connecting blocks 2 fixedly connected to the front and rear sides of the fixed outer shell 1, and connecting pipes 3 fixedly connected to the sides of the two connecting blocks 2 that are far apart from each other. A movable outer shell 4 is provided on the upper side of the fixed outer shell 1. Both the fixed outer shell 1 and the movable outer shell 4 are semi-cylindrical, and a connecting shaft 5 is rotatably connected between the fixed outer shell 1 and the movable outer shell 4. The fixed outer shell 1 and the movable outer shell 4 are rotatably connected through the connecting shaft 5. Each of the two connecting blocks 2 has a first connecting port 6 inside, and the two first connecting ports 6 extend out from the front and rear sides of the two connecting blocks 2, respectively. The front side of the 4 is provided with a second connection port 7. The two second connection ports 7 form a circular groove. The second connection port 7 is adapted to the first connection port 6. The rear walls of the two second connection ports 7 extend to the rear sides of the fixed shell 1 and the movable shell 4, respectively. The fixed shell 1 and the movable shell 4 are provided with a disassembly and assembly mechanism. The disassembly and assembly mechanism can connect and disconnect the fixed shell 1 and the movable shell 4. The disassembly and assembly mechanism includes two first fixing blocks 8, two second fixing blocks 9, two fixing bolts 10, two limiting ring grooves 11, two filter screens 12, baffle 13, sealing gasket 14, push plate 15, two sealing ring grooves 16, two connecting rings 17 and two sealing rings 18.

[0041] Furthermore, two first fixing blocks 8 are fixedly connected to the left side of the fixed housing 1, and the two first fixing blocks 8 are arranged front to back. Two second fixing blocks 9 are fixedly connected to the left side of the movable housing 4, and the two second fixing blocks 9 are also arranged front to back. The first fixing blocks 8 and the second fixing blocks 9 are adapted to each other. Two fixing bolts 10 are respectively set on the upper side of the two second fixing blocks 9, and the lower end of the fixing bolts 10 passes through the first fixing blocks 8 and the second fixing blocks 9. The first fixing blocks 8 and the second fixing blocks 9 are fixedly connected together by the fixing bolts 10. Two limiting ring grooves 11 are respectively opened on the inner surface of the fixed housing 1 and the movable housing 4. The two limiting ring grooves 11 are arranged front to back. Half of the limiting ring grooves 11 are opened on the fixed housing 1 and the movable housing 4 respectively. Two filter screens 12 are respectively set Inside the two limiting ring grooves 11, a baffle 13 is disposed between the two filter screens 12. The front and rear sides of the baffle 13 are fixedly connected to the opposite surfaces of the two filter screens 12, respectively. The baffle 13 is a semi-circular arc plate. A sealing gasket 14 is fixedly connected to the lower side of the movable housing 4. The sealing gasket 14 can contact the upper side of the fixed housing 1. A push plate 15 is fixedly connected to the inner surface of the baffle 13. Two sealing ring grooves 16 are respectively opened on the inner surfaces of the two second connection ports 7. Two connecting rings 17 are respectively fixedly connected to the opposite surfaces of the two first connection ports 6. The two connecting rings 17 extend into the interior of the two second connection ports 7. Two sealing rings 18 are respectively fixedly sleeved on the inner surfaces of the two connecting rings 17. The two sealing rings 18 are respectively rotatably connected to the interior of the two sealing ring grooves 16.

[0042] When starting work, if the internal structure of the dryer filter needs to be replaced, the operator removes the two fixing bolts 10, thereby releasing the fixed connection between the first fixing block 8 and the second fixing block 9. This allows the movable outer shell 4 to be opened, releasing the two limiting ring grooves 11 on the upper side from limiting the two filter screens 12. Rotating the filter screen 12 causes the baffle 13 to rotate synchronously, which in turn causes the push plate 15 to rotate synchronously. This pushes the desiccant at the bottom, which is difficult to remove, making it easier to remove. Simultaneously, moving it upwards allows the two filter screens 12 and the baffle 13 to be removed and replaced. During installation, first, the two filter screens 12 are placed inside the two limiting ring grooves 11 on the fixed outer shell 1. Then, rotating the filter screen 12 causes the baffle 13 to move, thus moving the baffle 13... A portion of the filter moves to the upper side, at which point desiccant is added between the two filter screens 12. The baffle 13 then blocks the added desiccant, preventing it from falling off when it exceeds the upper side of the fixed housing 1. This allows for the addition of more desiccant, ensuring the drying performance of the filter. At the same time, the sealing gasket 14 improves the sealing between the fixed housing 1 and the movable housing 4, preventing leakage of the filter. The sealing ring 18 is rotatably connected inside the sealing ring groove 16, ensuring that there is no leakage between the two movable housings 4 and the two first connection ports 6, further improving the sealing performance of the filter. In this way, the desiccant can be replaced without removing the filter from the equipment, thus saving replacement costs and improving replacement efficiency, thereby enhancing the practicality of the filter.

[0043] Working principle: When starting work, if the internal structure of the dryer filter needs to be replaced, the operator removes the two fixing bolts 10, thereby releasing the fixed connection between the first fixing block 8 and the second fixing block 9. This allows the movable outer shell 4 to be opened, releasing the two limiting annular grooves 11 on the upper side from limiting the two filter screens 12. Rotating the filter screen 12 causes the baffle 13 to rotate synchronously, which in turn causes the push plate 15 to rotate synchronously. This pushes the desiccant at the bottom, which is difficult to remove, to move, making it easier to remove. Simultaneously, moving it upwards allows the two filter screens 12 and the baffle 13 to be removed and replaced. During installation, first place the two filter screens 12 onto the fixed outer shell 1. The filter screen 12 is rotated inside the two limiting ring grooves 11, causing the filter screen 12 to move and drive the baffle 13 to move. A part of the baffle 13 moves to the upper side, at which time desiccant is added between the two filter screens 12. The baffle 13 then blocks the added desiccant, preventing it from falling off when it exceeds the upper side of the fixed housing 1, thus allowing more desiccant to be added and ensuring the drying performance of the dryer filter. At the same time, the sealing gasket 14 improves the connection sealing between the fixed housing 1 and the movable housing 4, preventing leakage of the dryer filter. The sealing ring 18 is rotatably connected inside the sealing ring groove 16, thus ensuring that there is no leakage between the two movable housings 4 and the two first connection ports 6, further improving the sealing performance of the dryer filter.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
