Abstract

A refrigerant recovering apparatus for refrigerating system features that it has a cavity with opening and a cutting mechanism in the cavity for cutting the pipe wall of refrigerating system. The opening is nested on the repair tube of compressor in sealing manner and operating the cutting mechanism cuts the repair tube to allow refrigerant to flow into the cavity and then to be recovered fully by pipeline connected to cavity. The apparatus can be optionally equipped with repair valve, meter, valves and joint for higher capability. It can also be used to collect the fluid in a full-enclosed system.

Description

Refrigerant recoverer for refrigerating system and uses thereof

The invention relates to the technical scheme of the refrigeration working medium (mainly being the fluorine Lyons refrigerant that atmospheric ozone layer is had the heavy damage effect at present) that reclaims in the present widely used refrigeration plant.The present invention also is applicable to the collection of other totally-enclosed system inner fluid.

The overwhelming majority such as present widely used refrigerating plant such as refrigerator, air conditioner, refrigerator all are to use mobile refrigeration working medium.Under normal circumstances, cold-producing medium is sealed in the refrigeration system, can not leak into and cause environmental pollution in the atmosphere.But when refrigeration system take place to be leaked or refrigeration system inside is out of order when needing place under repair, perhaps refrigerating plant is ended when scrapping service life, present processing method all be the cold-producing medium in the refrigeration system is discharged in the atmosphere (non-enclosed refrigeration plant can reclaim cold-producing medium, but this kind equipment because of leak and pollute use greatly less).Because a large amount of uses of refrigeration plant, the ozone layer that the cold-producing medium of so a large amount of dischargings just particularly plays an important role to the environment of preserving our planet to environment has caused serious destruction.

The purpose of this invention is to provide a kind of simple in structure, not high easy and simple to handle again being used to of cost and reclaim the recover of refrigeration working medium in the above-mentioned refrigerating plant, the present invention also can be used to reclaim the fluid in the similar whole closing appliance.

The present invention is achieved in that the cavity that has opening with, and being equipped with in the cavity can be from a kind of like this utensil of the cutting mechanism of cavity external control, opening part is installed in the suitable position (as the repairing pipe joint of fully closed compressor) of the refrigeration system that needs refrigerant emission, and the junction sealed, handle the interior cutting mechanism of cavity then and cut the pipeline or the outer wall of refrigeration system, cold-producing medium in the refrigeration system will be discharged in the cavity, by being connected container with pipe connecting structure that cavity communicates, the cold-producing medium that is discharged in the cavity will enter container and not be discharged in the atmosphere, if the adjunction vavuum pump is bled on this pipe connecting structure, just can reclaim the cold-producing medium in the refrigeration system fully.

Use the present invention that the cold-producing medium in the refrigeration system is reclaimed completely, this mainly contains the benefit of three aspects: one, user of the present invention can utilize by the recovery cold-producing medium again and save the money spending, increase income, using the present invention is very worthwhile concerning the user; Two, well-known; the cold-producing medium that is used in a large number is chlorine fluorine hydrocarbon material (being commonly referred to as fluorine Lyons) at present; because these materials are discharged in the atmosphere in a large number; made the atmospheric ozone layer of protection environment for human survival " cavity " occur; threaten human existence; this has caused the great attention of international community, the United Nations in 1987 passed through " the Montreal Agreement book), decision is completely forbidden in the near future and is used chlorine fluorine hydrocarbon material.This proves absolutely that fluorine Lyons is polluted and has arrived flagrant stage.If the present invention is extensively promoted the use of, then can significantly reduce the discharging and the pollution of chlorofluoromethane refrigerant, (estimating can reduce in general the discharge capacity of 70-90%), this obviously has very significant meaning to the environmental protection of the whole earth.Three, after forbidding the chloro-fluoro-carbon kind cold-producing medium comprehensively, though will use the novel refrigerant that atmospheric ozone layer is not had destruction, but because novel refrigerant price is rather stiff (the present latter's domestic city field boundary price is about the former ten times), so user of the present invention will obtain appreciable income because of the recovery cold-producing medium utilizes again, still can greatly reduce the new pollution of novel refrigerant to environment simultaneously.

In addition; if promote the use of words of the present invention; most of cold-producing medium all can be recovered because of the environmental protection supervision with because of the consideration of economic interests; this may make to the requirement reduction of new refrigerant and lower the expense of developing, producing and use new refrigerant that this also will be the good thing with considerable economic and social benefit.User of the present invention can also avoid sucking the harm in fluorine Lyons.

Specify the CONSTRUCTED SPECIFICATION and the working condition of the concrete device that proposes according to the present invention below in conjunction with accompanying drawing:

This device is made up of housing (1), cutter (2) and (3) and (6), pipe joint (4), joint sealing shroud (5).Cutter is made up of the screw rod (6) of stationary knife (2) and moving knife (3) and promotion moving knife, and wherein stationary knife (2) and moving knife (3) are formed the cutting knife type cutter, and handle (7) is used for turn screw rod (6) to promote the usefulness of moving knife (3) feed cutting or withdrawing; Engage sealing shroud (5) and made by the flexible material in rubber school and so on, an end engages with shell nozzle (8) firm and air tightly; Pipe joint (4) communicates with cavity (9); Take suitable seal approach to make except opening (8) and pipe joint (4), cavity (9) each several part and hull outside all are isolated gastight.

When using this utensil to reclaim cold-producing medium, with openend (8) with engage repairing pipe (or claiming gas tube) (10) on the compressor that sealing shroud (5) is inserted in the refrigeration plant (refrigerator or air conditioner) that needs refrigerant emission, and repairing pipe (10) terminal (11) is between cutter stationary knife (2) and the moving knife (3), use pipe clamp (12) then or tighten joint sealing shroud openend (13), make the joint that engages sealing shroud and refrigeration system repairing pipe (10) be sealed to air tight state with the method that iron wire is tied up; Locate to connect in pipe joint (4) then and repair valve and (repair valve and use and debug as refrigeration plant, the maintenance personal is familiar with, therefore do not give among the figure and drawing), and connect vavuum pump and cold-producing medium storage tank by repairing valve, adjust earlier and repair valve connection vavuum pump, start to close after vavuum pump pumps the air in the cavity (9) and repair valve (this is for no air is sneaked into), turn handle (7) makes screw rod (6) promote moving knife (3) feed and cuts repairing pipe terminal (11) again, cold-producing medium in the refrigeration system will be cut discharge from repairing pipe terminal (11), adjust again and repair valve connection cold-producing medium storage tank, at this moment making cool intrasystem cold-producing medium will be through repairing the mouth of cutting of pipe terminal (11), cavity (9), pipe joint (4) is recovered with being entered by the control of the repairing valve that is connected with pipe joint (4) in the cold-producing medium storage tank, if between the repairing valve that is connected with pipe joint (4) and cold-producing medium storage tank, be connected in series vavuum pump again, then the cold-producing medium in the refrigeration system can be drained fully clean filling in the system cryogen jar.After having reclaimed cold-producing medium, this recover can not taken off, and to repair valve be next step debugging, REPSH repair shop utilization of refrigeration system and can be used to connect.
