Description

Technical Field

[0001] The utility model relates to the technical field of cold dryers, in particular to an energy-saving cold dryer with a drying tank. Background Technique

[0002] A cold dryer, namely the abbreviation of a refrigerated dryer, uses a refrigerant to exchange heat with compressed air, reduces the temperature of the compressed air to the dew point temperature range of 2-10°C, thereby removing moisture and impurities in the compressed air.

[0003] Existing cold dryers are all equipped with a heat dissipation mechanism. Under long-term operation, the external filter screen will be attached with dust or impurities, resulting in poor subsequent internal air circulation and poor heat dissipation effect. This is likely to cause the internal instruments of the cold dryer to overheat and malfunction. At the same time, the existing cold dryers do not have a filtering structure inside, resulting in impurities or dust in the air entering the instrument interior, leading to malfunctions. Therefore, an energy-saving cold dryer with a drying tank is proposed. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , an energy-saving cold dryer with a drying tank, including a housing 1, characterized in that: a heat dissipation and cleaning device 2 is arranged outside the housing 1, and a cold drying component 3 is arranged inside the housing 1;

[0022] The heat dissipation and cleaning device 2 includes a fan 201. The fan 201 is fixedly installed on the front surface of the housing 1. A filter net 202 is arranged outside the fan 201. A U-shaped block 203 is fixedly installed on the front surface of the housing 1. A first motor 204 is fixedly installed on the right side of the U-shaped block 203. A bevel gear rod 205 is rotatably connected inside the U-shaped block 203. A threaded bevel rod 206 is rotatably connected inside the U-shaped block 203. A moving plate 207 is threadedly connected to the outside of the threaded bevel rod 206. A collection box 208 is fixedly installed on the front surface of the housing 1.

[0023] Further, the cold drying assembly 3 includes a tank body 301. The tank body 301 is fixedly installed on the inner bottom wall of the housing 1. A second motor 302 is fixedly installed on the top of the tank body 301. A filter plate 303 is movably connected inside the tank body 301. A cold drying system 304 is arranged outside the tank body 301. A drying tank body 305 is fixedly installed on the inner bottom wall of the housing 1. A hydraulic cylinder 306 is fixedly installed on the inner bottom wall of the drying tank body 305. A drying plate 307 is fixedly installed on the top of the hydraulic cylinder 306.

[0024] Specifically, as Figure 3 shown, the cold drying system 304 is mainly composed of components such as a refrigeration compressor, a condenser, an evaporator, and an expansion valve. The refrigeration compressor compresses the refrigerant into a high-temperature and high-pressure gas, and then it is cooled into a liquid refrigerant through the condenser. After the liquid refrigerant is throttled and depressurized by the expansion valve, it enters the evaporator to perform a heat exchange with the compressed air, reducing the temperature of the compressed air, and the water vapor therein condenses into liquid water and is discharged, thereby achieving the purpose of drying.

[0025] Specifically, as Figure 3 shown, after using for a period of time, opening the first box door and the second box door can expose the filter plate 303 inside the tank body 301 and the drying plate 307 inside the drying tank body 305, so as to perform maintenance on the drying plate 307 and the filter plate 303, achieving the purpose of being reusable without replacing the filter plate 303 and the drying plate 307, and thus achieving the purpose of energy saving.

[0026] Specifically, as Figure 2 shown, the first motor 204 is a forward and reverse motor. A forward and reverse motor refers to a motor that can achieve forward and reverse rotation. The working principle of a forward and reverse motor is based on changing the phase sequence of the motor power supply to achieve the change of the rotation direction. In a three-phase asynchronous motor, by swapping any two phases, the rotation direction of the motor can be changed. This operation is called phase change, which allows the motor to run in different directions according to needs.

[0027] During implementation, the following steps are carried out for operation:

[0028] 1) First, dissipate heat through the fan 201 and prevent dust through the filter net 202, and then turn on the first motor 204 to drive the bevel gear rod 205 to rotate;

[0029] 2) Then drive the threaded taper rod 206 to rotate through the bevel gear rod 205, so as to control the moving plate 207 to drive the cleaning plate to clean the filter net 202;

[0030] 3) Then turn on the second motor 302 to drive the filter plate 303 to rotate, and send the gas into the tank body 301 through the connecting inlet pipe;

[0031] 4) Finally, perform cooling and drying treatment through the cold drying system 304, and then send it into the drying tank body 305 for secondary drying and storage.

[0032] In summary, for the energy-saving cold dryer with a drying tank, the heat inside the housing 1 is extracted by the fan 201 to dissipate heat from the inside of the housing 1, and then the filter net 202 is used to prevent external dust from entering the inside of the housing 1. Then turn on the first motor 204 to drive the bevel gear rod 205 to rotate, and the threaded taper rod 206 can be driven by the bevel gear rod 205 to control the up and down movement of the moving plate 207, so as to cooperate with the cleaning plate to clean the surface of the filter net 202. After long-term use, the cleaning plate and the filter net 202 can also be replaced or maintained separately, so as to achieve the purpose of facilitating the cleaning and maintenance of the filter net 202. The gas is sent into the tank body 301 inside the housing 1 through the connecting inlet pipe, and then turn on the second motor 302 to drive the rotating shaft to rotate, so as to drive the filter plate 303 to rotate, so as to filter the impurities in the gas. Then the filtered gas will enter the cold drying system 304 for cooling treatment, and after cooling, it will enter the drying tank body 305 for temporary storage. Then turn on the hydraulic cylinder 306 to drive the drying plate 307 to move up and down, so as to finally dry the gas inside the drying tank body 305, so as to ensure that the gas inside the drying tank body 305 is in a dry state, so as to achieve the purpose of facilitating the filtration of the internal gas.
