There is a gap between the spiral partition and the inner side of the shell to form a drainage ditch. During the dryer, the condensed moisture and oil particles are thrown to the wall of the drainage ditch due to centrifugal force and flow down. In this way, the moisture and oil in the air can be separated together to obtain clean dry air.

Description

The utility model relates to an air dryer with improved structure.

The structure of a commonly used air dryer is shown in Figure 1, which uses refrigerant 11 to condense the moisture in the humid air, and then separates the air from the condensed water to obtain dry air, wherein the refrigerant 11 is in a closed The refrigerant pipe 12 circulates in the circuit. The refrigerant 11 flows through a condenser 14 and a refrigerant drier 15 after being compressed by the compressor 13, and then flows back into the compressor 13 after passing through a heat exchanger 18. In the process, the cooling fan 17 It dissipates heat and the pressure of the refrigerant 11 is controlled by the pressure control valve 16. When the humid air enters the heat exchanger 18 through the air inlet 181, it is condensed by the action of the refrigerant 11 to produce water, which will be mixed with the air. When the air outlet 182 on the top of the heat exchanger 18, the water is discharged by the automatic drain 19, and part of the air is still mixed with the particulate water molecules and oil, so it is impossible to get completely clean dry air. This is the common air. Dryers are less than ideal.

The purpose of this utility model is to overcome the above-mentioned shortcomings, and propose an improved air dryer to obtain clean dry air.

The air dryer proposed by the utility model makes the refrigerant circulate in a closed refrigerant pipe loop, including: a compressor, a condenser, a refrigerant drier, a pressure control valve and a heat exchanger. After being compressed by the compressor, the refrigerant flows through a condenser and a refrigerant dryer, and is dissipated by a cooling fan and the pressure of the refrigerant is controlled by a pressure control valve. Dryer, the spiral dryer is an air duct with an opening at the lower end in the center of a drum-shaped shell and is connected upwards, and a spiral partition continuous from top to bottom is arranged on the periphery of the air duct to form Spiral air channel, the refrigerant pipe spirals upwards from the bottom to the outside of the air duct along the air channel, there is still a small gap between the spiral partition and the inner side of the shell to form a drainage ditch, and the bottom of the shell is conical It is also provided with a water outlet, the top side of the housing is provided with an air inlet connected with the air channel, the air inlet is also provided with an air compressor, and the top of the housing is provided with an air outlet connected with the air duct.

Below in conjunction with preferred embodiment and accompanying drawing, the utility model is described in detail as follows, wherein:

Fig. 1 is the structural diagram of existing air drier;

Fig. 2 is the structural diagram of the utility model air dryer;

Referring to Fig. 2, the part structure of the present utility model is identical with common people, as refrigerant 11 circulates in closed refrigerant pipe 12 circuits, refrigerant 11 flows through a condenser 14 and a refrigerant drier 15 after being compressed by compressor 13, wherein , the cooling fan 17 dissipates heat and the pressure of the refrigerant 11 is controlled by the pressure control valve 16 . The biggest difference between the utility model and the common air dryer is that the refrigerant 11 is guided by the refrigerant pipe 12 and flows through a spiral dryer 20, and the spiral dryer 20 is provided with a lower end in the center of a cylindrical shell 21. The air conduit 22 that is open and leads upwards. The periphery of the air conduit 22 is provided with a spiral partition 23 that is continuous from top to bottom to form a spiral air passage. Circling upwards, there is still a small gap between the spiral partition 23 and the inner side of the housing 21 to form a drainage ditch 24 for the condensed water to flow downward; the bottom of the housing 21 is conical and is provided with a drain Port 25, drain port 25 is connected with an automatic drainer 19 again, so that drain water automatically, the air inlet 211 that communicates with the air channel is provided on the top side of housing 21, and is provided with air compressor 30 at the air inlet 211 place, In order to pressurize the air entering the spiral dryer 20, the top of the housing 21 is provided with an air outlet 212 communicating with the air duct 22, through which the dried clean air is discharged.

When the humid air enters the spiral dryer 20 from the air inlet 211, the moisture in the humid air is condensed by the refrigerant 11 in the refrigerant pipe 12, and the air and moisture are compressed by the pressure of the air compressor 30, so that the air and moisture are separated by the spiral separator. The air channel formed by 23 circulates in a vortex shape. At this time, the water particles and oil particles are thrown to the ditch wall of the cylindrical drainage ditch 24 due to the centrifugal force, and flow down. In this way, the water and oil particles pass through layers Condensation, separation of layers, and flow down to the bottom of the spiral dryer 20, and then it is discharged by the automatic drain 19, and the clean dry air separated by water and oil enters from the bottom of the air duct 22, and then It is discharged from the air outlet 212 above it.

To sum up, the utility model overcomes the shortcoming that common air dryers cannot separate oil stains from air, and is actually a very novel and practical product.
