Waste refrigerant recycling and adjusting device based on weight change

Abstract

The invention provides a waste refrigerant recycling and adjusting device based on weight change. The waste refrigerant recycling and adjusting device comprises a main seat and two recycling tanks, two air holes which respectively communicate with an air pipe are formed in the side wall of an adjusting seat, a driving plate is movably connected to the front surface of a driven plate, a rotating pawl is movably inserted in the inner part of the driven plate, a second gear is fixedly connected to the front face of the rotating pawl, a tooth section is arranged at the top of the driving plate, areset assembly is installed on one side, close to the driven plate, of the driving plate, and electromagnets corresponding to two strong magnets respectively are fixedly installed in the inner part ofthe main base. According to the waste refrigerant recycling and adjusting device based on weight change, when the weight of one recycling tank is increased to a certain degree, the recycling tank moves downwards to touch a switch, the electromagnets are powered on temporarily, the driving plate is pushed, then the driven plate is driven by the driving plate, the adjusting base rotates, an air inlet pipe is adjusted to be opened and closed, refrigerants enter the other recycling tank, and the situations that too many refrigerants are recycled in the recycling tanks, and potential safety hazards exist are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of refrigerant recovery, and in particular relates to a waste refrigerant recovery regulating device based on weight change. Background technique [0002] With the improvement of people's living standards and the rapid development of technology, the development of electrical products is also changing with each passing day. The problem that comes with it is the generation of a large amount of electrical and electronic waste. Discarded refrigerators and air conditioners are the two main categories of electrical and electronic waste. , Refrigerants in discarded refrigerators and air conditioners are not dangerous, but they contain freon, and if they are directly discarded or discharged into the air, they will cause damage to the environment, especially the ozone layer, and there are environmental risks. Attention should be paid to the recovery and harmless treatment of the refrigerant in it. [0003] At presen...

[0002] With the improvement of people's living standards and the rapid development of technology, the development of electrical products is also changing with each passing day. The problem that comes with it is the generation of a large amount of electrical and electronic waste. Discarded refrigerators and air conditioners are the two main categories of electrical and electronic waste. , Refrigerants in discarded refrigerators and air conditioners are not dangerous, but they contain freon, and if they are directly discarded or discharged into the air, they will cause damage to the environment, especially the ozone layer, and there are environmental risks. Attention should be paid to the recovery and harmless treatment of the refrigerant in it

[0003] At present, in the process of recovering refrigerant by the compression condensation method, the suction connection pipe of the recovery machine is connected to the process pipe of the compressor. After the connection is completed, the recovery machine is started. The recovery machine uses the suction capacity of the compressor to pass the refrigerant through a The larger dry filter is pumped into the compressor, compressed and discharged into the condenser for exothermic condensation, and finally discharged into the recovery gas tank. While discharging refrigerant into the recovery gas tank, attention should be paid to the recovery of the gas tank. Weight, because it is very dangerous to overcharge the refrigerant, in order to avoid the recovery gas tank from being overweight, it is generally adopted to stop working before the refrigerant is overcharged, or to install a pressure and weight detection device and a reversing diversion adjustment device , introduce the refrigerant into another recovery gas tank, the former has a great influence on the recovery efficiency of the refrigerant, and the latter requires the installation of many electrical equipment, which not only cost a lot, but also need to work all the time, consuming more power , which increases the cost of production
