Abstract
The utility model discloses a dry filter, which is composed of a main body of which one end is sealed and the other end is provided with a combined in-out pipe port, desiccant which is arranged in the main body, a filter screen which is lined by a poriferous metal plate, a spring, a spring seat, etc. The utility model has the advantages that refrigerant flows through the drying desiccant for multiple time, so the refrigerant can be dried thoroughly. The filtering screen has high strength and can bear a large impact force. The desiccant can not flow to a compressor together with the refrigerant becaused of the breakage of the filtering screen even when the desiccant obsorbs water and expands, so a compressor system is ensured to run normally. In addition, the utility model also has the advantages of small overall size, material saving, low manufacture cost, etc.
Description
The utility model relates to the device for drying and filtering in the air conditioner cooling cycle system.
In air conditioner cooling cycle system, as being mixed with moisture content and impurity in the cold-producing medium, comprise the residual chip of process pipeline, oxide skin and other foreign matter, the capital produces " ice is stifled " or " dirty stifled " at capillary and expansion valve, cause the cold-producing medium can not circulation cycle, not only so can not play the effect of refrigeration or heating, even can cause the air compressor motor insulating properties to reduce or make phenomenon such as the rotten deterioration of refrigerator oil, the effect of device for drying and filtering is exactly moisture and the foul that is used for removing in the cold-producing medium.Existing device for drying and filtering generally is made up of dress screen pack of detailed catalogue or porous copper strap plate and drier in the main body of both ends open.Cold-producing medium flows into from arrival end, and flow through drier and screen cloth flow out from the port of export again, thus the purpose that reaches dry moisture content and filter foreign matter.Its defective has: (1) screen pack is generally thinner, easily causes stressed excessive the breaking of screen pack owing to drier impact filtration net when cold-producing medium flows through, and break back drier and foreign matter flow to compressor together in company with cold-producing medium, and compressor assembly is destroyed; (2) cold-producing medium is too short drying time, only flows through drier once, under the drier condition of limited, can not guarantee that cold-producing medium obtains abundant drying, and the cold-producing medium that contains moisture content can make compressor assembly unusual; (3) the drier segment length is fixed, and when the drier imbibition, can produce big pressure to screen pack and the other end, also can cause screen pack to break and compressor assembly is destroyed; (4) global design heaviness is not suitable for the small and exquisite various development trend of modern air conditioning.
The purpose of this utility model all provides the device for drying and filtering that a kind of structure is small and exquisite, save material, reduce cost in the defective that overcomes prior art, and structurally improve port organization, increase screen pack intensity, improve force-bearing situation, preventing to break makes cold-producing medium obtain fully dry and guarantees that the compressor assembly operation is normal.
For achieving the above object, the utility model is realized by following technical proposal: this device for drying and filtering, include main body, be provided with drier and screen pack in the main body, it is characterized in that: described main body one end of a. is shut, only have the mouth of pipe into and out of unification, drier is being shut between end and the screen pack; B. described screen pack back side lining is equipped with expanded metal.
Described main body is provided with spring being provided with into and out of nose end and its fixing spring base between spring base and the expanded metal.
The utility model is improved to a port to the structure of former device for drying and filtering by two ports, strengthened screen pack intensity, technical measures such as drier segment length have been increased, so have following advantage: (1) cold-producing medium circulates repeatedly in drier, guaranteed that cold-producing medium obtains bone dry, increase dryer section length, made that the space between the desiccant particle increases, reduced the resistance when cold-producing medium passes through drier; (2) screen pack integral body has enough big intensity, can bear greater impact power, and screen pack can move around between the device for drying and filtering main body, after the drier imbibition, the stressed spring that passes to of screen pack, improved the force-bearing situation of screen pack, avoided the destruction of screen pack and cause drier to flow to compressor in company with cold-producing medium, guaranteed that the unimpeded and compressor assembly of cold-producing medium circulation cycle normally moves with foreign matter; (3) owing to adopted technique scheme, can reduce the dry filter overall dimension, save material, reduce manufacturing cost.
Accompanying drawing 1 has provided the utility model structural representation.
To be described in detail again the utility model by above-mentioned accompanying drawing below.
As shown in Figure 1, device for drying and filtering has a copper body (6), main body one end is the reducing mouth of pipe (1) into and out of unification, the other end is for shutting end, main body is shut and is provided with drier (7) in the end, stop and built-in by the screen pack (5) of metallic sieve system, and the back side of screen pack lining is equipped with expanded metal (4) and uses and improve screen pack intensity.Earlier that screen pack and expanded metal riveted is fastening good before the assembling.
Main body is provided with by the fixing spring base (2) of necking down process near nose end, be provided with spring (3) between spring base and the expanded metal, the setting of this spring can make screen pack be operated in also can have flexible possibility in main body under the situation that improves intensity, improve the screen pack force-bearing situation, prevent to break and cause compressor to destroy.
The utility model is put into the main body inner chamber successively with drier, the screen pack that is lined with expanded metal, spring, spring base, and then carries out the fixing and mouth of pipe necking down process to the reducing of spring base.
Claims (2)
1. a device for drying and filtering includes main body (6), is provided with drier (7) and screen pack (5) in the main body, it is characterized in that:
A. described main body one end is shut, and only has the mouth of pipe (1) into and out of unification, and drier is being shut between end and the screen pack;
B. described screen pack (5) back side lining is equipped with expanded metal (4).
2. device for drying and filtering as claimed in claim 1 is characterized in that described main body (6) being provided with into and out of nose end and its fixing spring base (2), is provided with spring (3) between spring base and the expanded metal.
