The invention discloses a novel oil filter dryer assembly, which includes a compression spring, a shell, an inner cylinder cover, an inner cylinder, a molecular sieve, a flange, an end cover, a sealing ring and an O-ring, and the top of the inner cylinder An inner cylinder cover is installed at the opening, and both the inner cylinder and the inner cylinder cover are placed in the shell, wherein a compression spring is arranged between the inner cylinder cover and the top of the shell, and the bottom of the inner cylinder is placed on the flange, and through the flange The center and the eccentric part of the disc are respectively provided with a central hole and an eccentric hole. The beneficial effect of the present invention is that the structure replaces the vacuum cotton gasket in the original drying cylinder with a stainless steel wire filter, while increasing the strength of the filter. It can still ensure its good ventilation, which not only protects the molecular sieve, but also can effectively take away the oil on the filter, effectively enhance the oil filtering effect, and improve the service life of the drying cylinder; the quality of the filter is improved, and it will not be over It is damaged early so that it is blown out to produce impurities.
