Abstract

A drying filter relates to the technical field of refrigerant filtration and dehydration applied in air conditioning refrigeration cycle system, which includes a body, the two ends of which are open, filter screens arranged at two ends of the body and desiccant arranged among the filter screens. The desiccant is a solid filter element, which is opposite to the inlet end of the body and is provided with a groove. The back surface of the filter screens are provided with an expanded metal. As the filter screens are provided with the expanded metal, the utility model can bear larger refrigerant impulsive force and has the advantages of simple structure and easy machining; simultaneously the solid filter element can baffle the impact of the desiccant to the filter screens and can ensure the refrigerant to be fully dried. Besides, after absorbing water the desiccant can extrude an elastic element and can lead most force to be transferred to the elastic element, thus reducing the stress of the filter screens, so as to ensure the normal running of compressor system; besides, by adopting the structure, the utility model also has the advantages of small integrated dimension, material saving and low manufacture cost, etc.

Description

Device for drying and filtering

Technical field

The utility model relates to the device for drying and filtering of a kind of separation or decontaminating liquid, especially refers to a kind of air conditioner cooling cycle system that is used for, the filtration of cold-producing medium and the technical field that dehydrates.

Background technology

Along with the further raising of people's living standard and the improvement of quality of life, the application of air-conditioner is more and more universal, device for drying and filtering then is a vitals in the air-conditioner cooling cycle system, it can remove the moisture or the dirt of the cold-producing medium in the cooling cycle system, chip and other foreign matter as pipeline residual in the processing, in case these fouls produce " ice is stifled " or " dirty stifled " phenomenon in capillary and expansion valve, prevent that with this compressor, motor insulating properties from degenerating or the rotten deterioration of refrigerator oil.And existing general device for drying and filtering adopts the main body of both ends open mostly, detailed catalogue wire netting and granular drier are installed in the main body, cold-producing medium flows into from arrival end, pass through drier and screen pack successively, flow out from the port of export again, thereby the purpose that reaches dry moisture and filter foreign matter, but still have following defective: (1) is because screen pack is generally thinner, when cold-producing medium is flowed through device for drying and filtering, drier impact filtration net, screen pack is stressed to break more greatly and easily, and this makes drier and foreign matter to flow into compressor assembly with cold-producing medium, causes the destruction of compressor assembly; (2) because drier mostly is the granulin molecule sieve greatly, the slit is big, under limited drier situation, cold-producing medium is too short drying time, thereby can not guarantee that cold-producing medium obtains bone dry, this result will cause compressor assembly unusual, and foreign matter is flowed out with cold-producing medium; (3) because drier is comparatively at random, and be granule, thereby intensity is less, stress-bearing capability is also less, and when screen pack is installed, and is easy to make molecular sieve to be vibrated and cracked, thereby flow out with cold-producing medium, increased the dirt in the cold-producing medium on the contrary, and caused refrigeration system to degenerate; (4) global design is heavy, is not suitable for the small and exquisite development trend flexibly of modern air conditioning.

Summary of the invention

Technical problem to be solved in the utility model is to overcome above-mentioned shortcoming, provides that a kind of screen pack intensity is big, dry fully, the device for drying and filtering of compact conformation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this device for drying and filtering comprises the main body of both ends open, the screen pack that places two ends in the main body and the drier between screen pack, it is characterized in that: described drier is the solid filter core that relative main body entrance point has groove, and the described screen pack back side is lined with expanded metal.

Can be provided with the cushion block of adsorption capacity between the screen pack of described main body entrance point and the solid filter core.

Also can be provided with elastic component between the screen pack of the described main body port of export and the solid filter core.

Described elastic component is made up of packing ring and the spring leaf between packing ring and solid filter core.

The peristome of described solid filter core inner groovy roughly is horn-like, and the integral body of groove is funnel-shaped structure.

Compared with prior art, advantage of the present utility model is: (1) makes it can bear bigger cold-producing medium impulse force because the screen pack back side is lined with metallic plate with holes, and simple in structure, easy to process; (2) drier adopts the solid filter core that has groove, not only can slow down the impact of drier to screen pack, and can guarantee that cold-producing medium obtains abundant drying; (3) owing between the screen pack of the main body port of export and solid filter core, be provided with elastic component, after the drier imbibition, push elastic component like this, make most of power pass to elastic component, reduced the stressed of screen pack; (4) owing between the screen pack of main body entrance point and solid filter core, be provided with the cushion block of adsorption capacity, strengthened the drying capacity of drier; (5) owing to adopted technique scheme, can reduce the overall dimension of device for drying and filtering, save material, shorten the process time, improve productivity effect, reduce production cost.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

See Fig. 1 to Fig. 4, present embodiment comprises the copper body 1 of both ends open, the screen pack 2 that places two ends in the main body 1 and the solid filter core 4 between screen pack 2, the face of solid filter core 4 relative main body 1 entrance points is provided with groove 3, it is horn-like that the peristome of this groove 3 roughly is, the integral body of groove 3 is funnel-shaped structure, makes cold-producing medium be easy to flow in the groove 3; Described screen pack 2 back sides are lined with expanded metal 8, are used for improving the intensity of screen pack 2; In main body 1, also be provided with the good polyester cushion block 7 of adsorption capacity, the adsorption capacity of increase drier that can be covert between the screen pack 2 of entrance point and the solid filter core 4; Between the screen pack 2 of main body 1 port of export and solid filter core 4, be provided with elastic component, this elastic component is made up of stainless steel packing ring 6 and the stainless steel spring sheet 5 between stainless steel packing ring 6 and solid filter core 4, make after the drier imbibition, the extruding elastic component, can make most power pass to elastic component, reduce the stressed of screen pack 2, reduced the possibility that screen pack 2 breaks.

The utility model is before assembling, earlier firm good screen pack 2 and porous metals 8 plate riveteds, then the screen pack 2 that is lined with expanded metal 8, stainless steel packing ring 6, stainless steel spring sheet 5, solid filter core 4 and polyester cushion block 7 are put into main body 1 inner chamber made of copper successively, carry out mouth of pipe necking down process again.
