Ultrahigh-pressure refrigeration dryer

Abstract

The invention relates to the technical field of freeze drying equipment, and discloses an ultrahigh-pressure refrigeration dryer, which comprises a base, a shell and supporting legs, wherein the shellis fixedly arranged on the upper surface of the base, a bottom seat is fixedly arranged on the left side of the bottom in the shell, an air compressor is arranged above the bottom seat, and a heat exchanger shell is arranged on the right side of the air compressor. According to the invention, a sound absorption cotton layer, a porous plastic layer and a sound absorption rubber layer are sequentially arranged on the outer shell of the air compressor from inside to outside, so that the noise pollution generated in the working process of the refrigeration dryer is effectively reduced; by arranging a rubber pad, a telescopic rod, a spring, a rubber block and a supporting column, potential safety hazards caused by vibration of the air compressor are reduced while the situation that abnormal sound is generated due to vibration of the air compressor is relieved; and self-locking universal wheels are arranged in the supporting legs, and can be conveniently folded when not used, so that the practicability is improved, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of freeze-drying equipment, in particular to an ultra-high pressure freeze-dryer. Background technique [0002] The cold dryer is the abbreviation of the refrigerated dryer. The cold dryer is a new technology and belongs to the air source processing element in the pneumatic system. The compressed air first enters the pre-cooler for air-cooled or water-cooled heat exchange to remove part of the heat. Then it enters the pre-cooler, and exchanges heat with the cold air that has been cooled to the pressure dew point from the evaporator, so that the temperature of the compressed air is further reduced, and then the compressed air enters the evaporator, exchanges heat with the refrigerant, and the temperature of the compressed air When the temperature drops to 0-8°C, the low-temperature air enters the hot and cold air exchanger for heat exchange, and after the temperature rises, it is output through the exhaust pi...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the air compressor of the cold dryer often produces abnormal sound due to vibration during operation, which causes a certain amount of noise pollution in the working environment, which not only endangers the health of the staff, but also the wheels of the cold dryer directly Exposure to the outside, if the brakes are not stepped on in time or the brakes fail for a long time, the equipment will be in a state of moving at any time, resulting in instability, and unsafe factors will occur
