Abstract
The utility model relates to a freon recovery device composed of a low-voltage sucking fluorine inlet three-way valve, a drying filter, a gas-liquid separator, a rotary compressor, a condensator, a liquid reservoir, a high-pressure outlet liquid recovery three-way valve; the components are successively communicated by pipelines. Another two branches of the low-voltage sucking fluorine inlet three-way valve are respectively provided with a low-pressure gauge and a sucking fluorine rubber tube, and another two branches of the high-pressure outlet liquid recovery three-way valve are respectively provided with a high pressure gage and a liquid outlet tube. The system is provided with a conventional power circuit. The utility model has simple operation and is convenient in recovering the freon when refrigeration devices are repaired; thus, the utility model avoids of waste and environmental pollution of the freon.
Description
The utility model relates to a kind of freon recovering device.
The refrigeration agent that uses on chiller plant at present mainly contains F-12, F-22.When equipment breaks down when keeping in repair, generally all be earlier with the freon drainage.Both wasted freon, again befouling environment.
The purpose of this utility model provides a kind of device that reclaims freon when chiller plant keeps in repair.Thereby avoid the waste of freon and to the pollution of environment.
The purpose of this utility model is achieved in that this device has a rotary compressor, and the inlet tube of rotary compressor is communicated with the outer pipe of gas-liquid separator, and the inlet tube of gas-liquid separator is communicated with the outer pipe of device for drying and filtering; The inlet tube of device for drying and filtering is inhaled fluorine air inlet three-way valve with low pressure and is communicated with, low pressure is inhaled two branch roads in addition of fluorine air inlet three-way valve, one the tunnel connects low-pressure meter, another road dress is inhaled fluorine rubber-pipe, and the outer pipe of rotary compressor is communicated with the condenser inlet pipe, and the outer pipe of condenser is communicated with the inlet tube of cistern, the outer pipe of cistern reclaims three-way valve with high press juice and is communicated with, high press juice reclaims two branch roads in addition of three-way valve, and one the tunnel connects high pressure gauge, the drain pipe that another road dress can be connected with the recovery steel cylinder.This system is furnished with conventional power circuit.
Fig. 1 is the utility model system schematic;
Fig. 2 is the utility model power circuit diagram.
Describe in detail below in conjunction with accompanying drawing:
Newly show according to Fig. 1, this device has a rotary compressor 7, the inlet tube of rotary compressor 7 is communicated with the outer pipe of gas-liquid separator 5, the inlet tube of gas-liquid separator 5 is communicated with the outer pipe of device for drying and filtering 3, the inlet tube of device for drying and filtering 3 is inhaled fluorine air inlet three-way valve 2 with low pressure and is communicated with, low pressure is inhaled two branch roads in addition of fluorine air inlet three-way valve 2, and one the tunnel connects low-pressure meter 6, and another road dress is inhaled fluorine rubber-pipe 1; The outer pipe of rotary compressor 7 is communicated with condenser 12 inlet tubes, the outer pipe of condenser 12 is communicated with the inlet tube of cistern 13, the outer pipe of cistern 13 reclaims three-way valve 11 with high press juice and is communicated with, high press juice reclaims two branch roads in addition of three-way valve 11, one the tunnel connects the drain pipe 10 that high pressure gauge 9 another road dresses can be connected with the recovery steel cylinder, this system is furnished with conventional power circuit, as shown in the figure.
During use, earlier freon is reclaimed steel cylinder and puts into cold water and cool off, again with drain pipe 10 with reclaim steel cylinder and connect, and open high press juice and reclaim three-way valve 11, and then the effective micro-knife of the region between the heart and the diaphragm that chiller plant is repaired mouthful cut off, insert rapidly to inhale in the fluorine rubber-pipe 1 and be communicated with, tight with the personality card subcard.Connect power supply, tutorial light Z is bright, press button TA, contactor J inhales platform, rotary compressor 7 and condenser 12 work, open low pressure subsequently and inhale fluorine air inlet three-way valve 2, freon is then inhaled fluorine air inlet three-way valve 2 through low pressure and is entered device for drying and filtering 3, after filtering dirt and moisture content, enter rotary compressor 7 through gas-liquid separator 5, be compressed into pressurized gas, after condenser 12 coolings, become highly pressurised liquid, enter the recovery steel cylinder through cistern 13 high press juices recovery three-way valve 11 and drain pipe 10, realize that freon reclaims.After treating that low-pressure meter 6 is negative pressure, close low pressure and inhale fluorine air inlet three-way valve 2, press button OA, cut off the electricity supply, close high press juice at last and reclaim three-way valve 11.
For preventing when changing device for drying and filtering 3, to let out fluorine or in system, advance air, can be provided with a solenoid valve 4 on the connecting pipeline between said gas-liquid separator 5 and the device for drying and filtering 3.
For avoiding system's internal pressure too high, cause system failure, the outer pipe of said rotary compressor 7 can have a branch road in addition, installs a pressure relay 8.When overpressure, this actuating of relay with circuitry cuts, thereby plays a protective role.
The utlity model has simple to operate, refrigeration plant when maintenance freon recovery side Just advantage has been avoided the waste of freon and to the pollution of environment, has been comparatively a kind of Desirable freon recovery device.
