Novel bidirectional liquid pipe drying and filtering device for heat pump and manufacturing method of novel bidirectional liquid pipe drying and filtering device

Abstract

The invention discloses a novel bidirectional liquid pipe drying and filtering device for a heat pump and a manufacturing method of the novel bidirectional liquid pipe drying and filtering device. The liquid pipe drying and filtering device comprises a copper pipe and end covers; a rotary filter element body comprising a drying cylinder and locating plates is arranged in the copper pipe; the locating plates are located at two sides of the drying cylinder; a drying pipe is arranged inside the drying cylinder; negative-pressure plates are uniformly arranged at the outer side of the drying pipe; two ends of the rotary filter element body are connected with limited posts through sealing covers; and the limited posts are fixedly connected with the copper pipe through cross beams. The manufacturing method comprises the steps of 1) manufacturing the copper pipe and the end covers; 2) manufacturing and assembling the rotary filter element body; 3) assembling the rotary filter element body and the copper pipe; 4) sealing the end covers; and 5) testing the liquid pipe drying and filtering device. The manufacturing method disclosed by the invention is simple in step and convenient to mount and dismount; and not only are the sealing, drying and filtering effects of the drying and filtering device improved, but also the working stability of the whole drying and filtering device is improved, and the manufacturing process is shortened.

Description

technical field [0001] The invention relates to a novel bidirectional heat pump liquid pipe drying filter and a manufacturing method thereof. Background technique [0002] A heat pump is a device that transfers heat energy from a low-level heat source to a high-level heat source. Usually, it first obtains low-level heat energy from natural air, water or soil, performs work through electricity, and then provides usable high-level heat energy to people. The liquid pipe drier filter is an important part in the heat pump system, mainly used to absorb moisture in the refrigeration system and remove impurities in the refrigerant. [0003] The dry filter for liquid pipes announced by the State Intellectual Property Office of China (application number: 201420622866.1, announcement number: CN204254943, announcement date: 2015.04.08), which includes a tank body, is characterized in that the tank body includes a cylindrical body part , the constriction part integrally extended from bo...
