Embodiment 1

[0039] Embodiment 1: as shown in Figure 6, the concrete steps of the present invention are as follows:

[0040] (1), first select the SPCE cold-rolled steel strip, thickness 0.5mm, C<0.08%, Mn<0.4%, P<0.03%, S<0.03%, Si<0.03%, the width is the same as the circumference of the dry filter cylinder Steel strips of equal length are welded by high frequency into steel pipes;

[0041] As shown in Figure 1:

[0042] (2), then the steel pipe manufactured in step (1) is cut to length according to the model of the dry filter, and the burrs are removed at the cut steel pipe two ends;

[0043] (3), then step (2) handles blank 11 and does inner and outer surface treatment:

[0044] a. Put the billet into the alkali tank for 20 minutes at a temperature of 80°C,

[0045] b. Shake and wash in tap water for 20 seconds,

[0046] c. Put the billet into the acid tank and shake it six times, and leave it for 60 minutes.

[0047] d. Then shake and wash in the tap water tank for 20 seconds,

Abstract

The invention relates to a method for producing iron drying filter of refrigerator and air conditioner or the like. The invention uses steel band via high-frequency welding to obtain steel tube, to be cut into steel tubes, then treats the inner and outer faces of the steel tube, stuffs a filter screen, a molecule screen, and a copper cap, plates paint on the face of the blank, and vacuums and packs. The invention can effectively reduce the cost of filter.

Description

technical field [0001] The invention relates to a method for manufacturing an iron dry filter used in refrigeration equipment such as air conditioners and refrigerators, and relates to the technical field of refrigeration equipment manufacture. Background technique [0002] The function of the dry filter is: in order to prevent the refrigerant from containing water or water from entering the system due to irreducible elements, when the high-temperature liquid from the condenser enters the expansion valve, the temperature of the liquid will be greatly reduced. The drop is generally below zero. If there is water in the system at this time, the cross-section through which the expansion valve passes is very small, and ice blockage will easily occur, which will affect the normal operation of the system. [0003] At present, most of the drying filters in refrigerator refrigeration accessories are made of copper or aluminum. This will gradually increase the manufacturing cost of re...
