Embodiment 1

[0022] Embodiment 1: as figure 2 As shown, it includes a cylinder body, a left end cap and a right end cap. The left end cap and the right end cap are respectively arranged on both sides of the cylinder body. The diameters of the left end cap and the right end cap are slightly larger than the outer diameter of the cylinder body, so The center of the left end cover is provided with an air intake hole, and the edge of the air intake hole is provided with a first connecting portion, the first connecting portion is a first protruding ring stamped from the edge of the air intake hole, the first protruding ring The outer surface is welded with an air inlet pipe, and the air inlet pipe is coaxial with the air inlet hole, and the center of the right end cover is provided with an air outlet hole, and the edge of the air outlet hole is provided with a second connecting part, and the second connecting part is the edge of the air outlet hole The second protruding ring is punched, the out...

Embodiment 2

[0031] Example 2, such as image 3 As shown, it includes a cylinder body, a left end cap and a right end cap. The left end cap and the right end cap are respectively arranged on both sides of the cylinder body. The diameters of the left end cap and the right end cap are slightly larger than the outer diameter of the cylinder body, so The center of the left end cover is provided with an air intake hole, and the edge of the air intake hole is provided with a first connecting portion, the first connecting portion is a first flanging formed by flanging outward at 90° from the edge of the air intake hole, and the The first flanging is welded with an air inlet pipe, and the air inlet pipe is coaxial with the air inlet hole, and the center of the right end cover is provided with an air outlet hole, and the edge of the air outlet hole is provided with a second connection part, which is the outlet The second flanging formed by the 90° outward flanging of the air hole edge, the second f...

Abstract

The invention discloses a novel drying filter and a preparation method thereof and belongs to the technical field of refrigerating accessories. The filter comprises a barrel body, a left end cover anda right end cover; the left end cover is provided with a gas inflow hole, and a gas inflow pipe is welded to the edge of the gas inflow hole through a first connection portion; and the right end cover is provided with a gas outflow hole, and a gas outflow pipe is welded to the edge of the gas outflow hole through a second connection portion. According to the novel drying filter and the preparation method thereof, due to the fact that to-be-welded faces of various parts are machined, oil dirt and impurities are removed due to cleaning of an ultrasonic cleaning machine; then the left end coverand the gas inflow pipe are subjected to friction welding to be made into a left end cover assembly; the right end cover and the gas outflow pipe are subjected to friction welding to be made into a right end cover assembly; finally, the two ends of the barrel body are subjected to friction welding with the left end cover assembly and the right end cover assembly correspondingly, and a finished filter is made; and flame brazing and carbon dioxide protecting welding are changed into friction welding, the energy consumption can be greatly lowered, the leaking rate of the welded portion is lowered, and the phenomenon that due to flame brazing, the welded portion is dirty in surface and has residues is improved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration accessories, and in particular relates to a novel dry filter and a preparation method thereof. Background technique [0002] With the further improvement of people's living standards and quality of life, the application of air conditioners has become more and more popular. However, the components of the refrigeration system generally have different amounts of moisture before assembly, and will carry a large amount of moisture during operation. Impurities. Therefore, as a device often installed in the refrigeration system pipeline, the dry filter plays a vital role in the refrigeration system. It can dry and filter the original moisture in the refrigeration system and the impurities generated during operation. , improve the cooling effect and the service life of the compressor. [0003] Such as figure 1 As shown, the existing dry filter includes a cylindrical body, an air inlet pipe, a lef...
