Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning systems, in particular to a circulation filter applied to an air-conditioning pipeline system. Background Art

[0002] At present, large air conditioners are equipped with a lot of piping after leaving the factory. The piping is particularly complex and requires on-site welding during installation. Because there are so many pipes and many parts that need to be welded, a lot of metal impurities will be generated during welding. These impurities will flow into the system with the refrigerant and be carried into the heat exchanger or compressor, which will reduce the life of the compressor, reduce the heat exchange efficiency of the heat exchanger, reduce the efficiency of the entire air conditioner, increase power consumption, and reduce the life of the air conditioner.

[0003] A conventional filter is a straight cylinder with a filter installed inside. When the refrigerant flow rate is high, some impurities may break through the filter and flow into the system, participating in the system circulation. Utility Model Content

[0012] The utility model provides a circulating filter for use in an air-conditioning piping system, in which a filter element is fixedly arranged in a settling pipe, and impurities are effectively filtered out through the filter element. In addition, compared with a single-layer filter screen, a filter element is arranged to fill the settling section and the straight section, so that the adequacy and reliability of impurity filtering can be improved, and the risk of impurities rushing out of the filter and flowing into the system due to a large refrigerant flow rate can be reduced. The settling section is recessed downward relative to the straight section, and a settling tank is provided at the bottom of the settling section, so that impurities can be concentrated and precipitated in the settling tank, effectively preventing impurities from adhering to the filter element, and preventing impurities in the settling tank from flowing as the system pressure changes.

[0017] 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.

[0018] The purpose of the utility model is to provide a circulation filter applied to an air conditioning pipeline system to solve the problems existing in the above-mentioned prior art and to effectively improve the filtering ability of impurities.

[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-Figure 2As shown, the utility model provides a circulating filter used in an air-conditioning pipeline system, including a sedimentation pipe and a filter element 3. The middle part of the sedimentation pipe is a sedimentation section 5. The bottom of the sedimentation section 5 has a sedimentation tank 2. Both ends of the sedimentation pipe are straight sections 4. The sedimentation section 5 is recessed downward relative to the straight section 4. The filter element 3 is fixed in the sedimentation pipe, and the filter element 3 is filled into the sedimentation section 5 and the straight section 4.

[0021] The circulating filter provided by the utility model for use in an air-conditioning piping system has a filter element 3 fixedly arranged in a sedimentation tube, and impurities are effectively filtered out through the filter element 3. Compared with a single-layer filter screen, the filter element 3 is arranged to be filled in the sedimentation section 5 and the straight section 4, which can improve the adequacy and reliability of impurity filtering, and reduce the risk of impurities rushing out of the filter and flowing into the system due to a large refrigerant flow rate. The sedimentation section 5 is recessed downward relative to the straight section 4, and a sedimentation tank 2 is provided at the bottom of the sedimentation section 5, which can concentrate and precipitate impurities in the sedimentation tank 2, effectively preventing impurities from adhering to the filter element 3, and preventing impurities in the sedimentation tank 2 from flowing as the system pressure changes. Therefore, the circulating filter provided by the utility model for use in an air-conditioning piping system can effectively improve the filtering ability for impurities.

[0022] As a more preferred implementation of this embodiment, a cleaning port is opened on the sedimentation tank 2, and a blocking cover is detachably fixed at the cleaning port, and the blocking cover can block the cleaning port to facilitate disassembly, cleaning and maintenance.

[0023] As a more preferred implementation of this embodiment, the filter element 3 is a wavy filter mesh, and a plurality of folding lines are arranged on the wavy filter mesh. The plurality of folding lines are arranged at intervals along the sedimentation tube. The wavy filter mesh is folded back and forth in opposite directions along the folding lines in turn to form a wavy filter mesh with a cross-section of multiple "W" connected in turn. On the basis of not changing the size of the sedimentation tube, the filtration area is increased, and at the same time, the contact time between the refrigerant and impurities and the filter element 3 is increased, thereby improving the filtration effect. When the refrigerant passes through the folded wavy filter mesh, the impurities in the refrigerant are more likely to accumulate at the folding lines, thereby reducing the resistance to the circulation of the refrigerant caused by the accumulation of impurities after long-term use.

[0024] As a more preferred implementation mode of this embodiment, quick-connect structures are provided at both ends of the settling tube, and the quick-connect structures are used to be detachably fixedly connected to the refrigerant pipeline, which is convenient for installation, and is easy to disassemble, clean and repair.

[0025] As a more preferred implementation of this embodiment, the quick-connect structure is a nut 1, which has a simple structure and is easy to manufacture and use.

[0026] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
