Description

Technical Field

[0001] The utility model relates to the technical field of drying filter devices, in particular to a refrigerant drying filter. Background Art

[0002] Refrigerant, also known as refrigerant, is commonly known as snow in some southern regions. It is a working substance that continuously circulates in the refrigeration system and achieves refrigeration through its own state changes. The refrigerant absorbs the heat of the cooled medium in the evaporator and vaporizes, and transfers the heat to the surrounding air or water in the condenser to condense; the working fluid that completes the thermodynamic cycle in the refrigerator, it absorbs the heat of the cooled object at low temperature, and then transfers it to the cooling water or air at a higher temperature. In a vapor compression refrigerator, a working fluid that can be liquefied at room temperature or lower temperature is used as a refrigerant, such as Freon, hydrocarbons, ammonia, etc.; in a gas compression refrigerator, a gas refrigerant is used, such as air, hydrogen, helium, etc., and these gases are always in a gaseous state during the refrigeration cycle.

[0003] For example, a drying filter with the announcement number CN211876438U that saves disassembly during refrigerant filling includes a drying filter body, the left end of the drying filter body is provided with an outlet pipe for connecting to the high-pressure side, the right end of the drying filter body is provided with an inlet pipe for connecting to the low-pressure side, one end of the refrigerant filling pipe is sealedly installed on the side wall of the drying filter body and is connected to the interior of the drying filter body, one end of the refrigerant filling pipe is arranged close to the inlet pipe, the other end of the refrigerant filling pipe is provided with a one-way valve, the outer wall of the inlet pipe is provided with a dent protruding toward the interior of the inlet pipe, and the dent is used for axial limiting when connected to the high-pressure side pipeline.

[0004] The above-mentioned device allows the refrigerant to enter the drying filter through the refrigerant charging pipe, and enter the refrigeration system after being dried by the molecular sieve inside the drying filter and filtered by the filter. It not only effectively prevents and alleviates the blockage problem and extends the operation cycle of the refrigeration system, but also avoids the refrigerant backflow by setting a one-way valve. After charging and filling, it is directly connected or disconnected with the charging system without clamping to open the process pipe or welding to close the process pipe, thereby saving unnecessary trouble. However, generally speaking, the design of the above-mentioned device for drying and filtering the refrigerant requires that the refrigeration process be prolonged and the cycle be increased, which is equivalent to adding an extra step, greatly increasing the complexity of the refrigeration device. Utility Model Content

[0005] The purpose of the utility model is to provide a refrigerant drying filter to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a refrigerant drying filter, comprising a filter housing, an insertion end is arranged at the upper end of the filter housing, and a compression docking port is arranged at the bottom of the insertion end, and an inlay end is arranged in the middle of the compression docking port, an input port is arranged at the outer end of the compression docking port, and a diffusion end is arranged at the lower end of the input port, and abutment ends are arranged at the upper and lower ends of the output port, slide grooves are arranged at the left and right support ends, and active fixed ends are arranged at the slide grooves.

[0007] Preferably, a calcium chloride drying block is arranged inside the diffusion end, and a filter plate is arranged at the lower end of the calcium chloride drying block, and a plurality of filter holes are arranged on the surface of the filter plate.

[0008] Preferably, the lower end of the filter plate is connected to the output end, and the device connection end is arranged at the lower end of the output end.

[0009] Preferably, an external outlet is arranged at one side of the filter plate corresponding to the filter housing, and an open end is arranged at the external outlet, and a protruding end is arranged on the surface of the open end.

[0010] Preferably, an attachment plate is provided on the inner side surface of the opening end, and an elastic zipper is arranged at the lower end of the attachment plate, and a fixing pile is arranged at the lower end of the elastic zipper.

[0011] Preferably, the fixing pile is embedded in the inner side of the external outlet.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Compared with other refrigerant drying and filtering devices, this device is connected to the coolant delivery point through its simple design, so that the device can directly perform drying and filtering operations before use. In contrast, only a short step is needed to filter the coolant, saving the manufacturing cost of the device. It is also simple to manufacture, and only needs to add this drying filter to be placed at the front end of the coolant compressor. In addition, the device is internally provided with a filter plate that can be easily replaced. Long-term use of the drying filter will cause the filter plate to absorb too many impurities and various types of particulate matter, making the filtering effect of the filter plate worse. Therefore, timely replacement plays an important role in the efficiency of the device, and the open end of the filter plate provided by the device can make replacement convenient and simple.
