Description

Technical Field

[0001] The utility model relates to the technical field of refrigerant recovery devices, in particular to an environmentally friendly refrigerant recovery device. Background Art

[0002] Refrigerant, also known as refrigerant, is commonly known as snow in some southern regions. It is a working substance that continuously circulates in the refrigeration system and achieves refrigeration through its own state changes. The refrigerant absorbs the heat of the cooled medium in the evaporator and vaporizes, and transfers the heat to the surrounding air or water in the condenser to condense; the working fluid that completes the thermodynamic cycle in the refrigerator, it absorbs the heat of the cooled object at low temperature, and then transfers it to the cooling water or air at a higher temperature. In vapor compression refrigerators, the working fluid that can be liquefied at room temperature or lower temperatures is used as the refrigerant, such as Freon, hydrocarbons, ammonia, etc.; in gas compression refrigerators, gas refrigerants are used, such as air, hydrogen, helium, etc., and these gases are always in a gaseous state during the refrigeration cycle.

[0003] For example, a refrigerant recovery device with a publication number of CN116007246A includes an air-cooled heat exchanger, a control box, a compressor having an input port and an output port, a recovery structure, a first pipeline connected to an external device and the air-cooled heat exchanger, a second pipeline connected to the air-cooled heat exchanger and the input port of the compressor, a third pipeline connected to the output port of the compressor and the air-cooled heat exchanger, a fourth pipeline connected to the air-cooled heat exchanger and the recovery structure, and a detection device for collecting the superheat of the refrigerant output by the external device.

[0004] The above-mentioned device is connected to the control box through a detection device and a first control valve connected to the control box is arranged on the first pipeline. During the process of recovering the refrigerant, the first control box adjusts the opening of the first control valve according to the superheat of the refrigerant collected by the detection device, thereby ensuring that refrigerants in different forms can be recovered normally, so there is no need to manually switch the switch, thereby achieving automatic recovery function, reducing tedious human intervention or operation, and facilitating automation implementation. However, relatively speaking, this device is mainly used for recycling, and the recovery of the coolant is completely independent of manual labor. However, generally speaking, the automatic recovery function is mainly for the periodic cycle of the device, but this device does not fully achieve the effect of full circulation. Long-term cyclic use will lead to the formation of scale in the coolant, and the cooling effect of the cooling device will be reduced. Utility Model Content

[0005] The purpose of the utility model is to provide an environmentally friendly refrigerant recovery device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an environmentally friendly refrigerant recovery device, including a recovery box body, an electric motor is arranged on the front surface of the recovery box body, and a transmission line is arranged at the lower end of the motor, and an electric plug board is arranged at the lower end of the transmission line, a surface cover is arranged at the upper end of the recovery box body, and a connecting pipe is arranged in the center of the surface cover, and a compression box is arranged at the lower end of the connecting pipe, fixed brackets are arranged on both sides of the compression box and connected to the inner surface of the recovery box body, and a cylinder is arranged on the other side of the compression box, and a piston is arranged on the surface of the cylinder and connected to the motor on the outer surface.

[0007] Preferably, an air-cooled ventilation device is arranged on the back surface of the recovery box, and a layer of line pipe is arranged on the inner surface of the recovery box to connect the air-cooled ventilation device, and a plurality of exhaust ports are arranged at the bottom end of the air-cooled ventilation device.

[0008] Preferably, a gathering end surface is arranged at the bottom end of the recovery box, and a recovery pipe is arranged in the middle of the gathering end surface.

[0009] Preferably, a filter box is placed at the upper end of the gathered end surface, and a filter plate is placed at the lower end of the bottom of the filter box, and a plurality of filter ports are arranged at the middle section of the filter plate.

[0010] Preferably, a middle section pipe is arranged at one end of the filter box and connected to the air-cooled ventilation device, and a plurality of lower connecting pipes are arranged at the upper end of the filter box and connected to the lower surface of the compression box.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] Compared with other environmentally friendly refrigerant recovery devices, this device allows the refrigerant to enter the device directly after the cooling operation is completed by placing the upper connection port, and then uses the air compressor placed inside the device. The air compressor is directly driven by the electric motor to make the crankshaft rotate, drive the connecting rod to make the piston reciprocate, cause the cylinder volume to change, and compress the inside. The placement of this device facilitates the use of circulating coolant and reduces the compression of subsequent coolant. In addition, during the use of circulating coolant, long-term use may cause a series of impurities such as scale in the coolant. The generation of impurities will not only cause the circulation pipes between the components to be blocked, but also cause the cooling effect of the coolant to drop rapidly, resulting in poor cooling of the required cooling device, leading to mechanical overheating and other conditions. The filter plate placed inside the device can filter out the scale as much as possible. BRIEF DESCRIPTION OF THE DRAWINGS
