Abstract
The invention discloses a technology for processing a stainless steel filtering net. The technology comprises the following steps: (1) knitting stainless steel wire mesh raw materials into a stainless steel mesh by virtue of a high-precision knitting machine; (2) cutting the stainless steel mesh into rectangular mesh pieces of the needed filtering net size; (3) finishing the four sides of the mesh pieces, and removing the burrs; (4) putting the finished mesh pieces onto a fixed mold, and welding the mesh pieces into a mesh cylinder by utilizing a manual arc welding method; (5) performing heat treatment on the weld joint on the mesh cylinder; and (6) putting the mesh cylinder subjected to heat treatment into an ultrasonic cleaning pool for cleaning, thereby obtaining the stainless steel filtering net. According to the technology for processing the stainless steel filtering net disclosed by the invention, molybdenum-containing 316L stainless steel is adopted, and the stainless steel filtering net has the advantages of excellent corrosion resistance, atmosphere corrosion resistance and high temperature resistance and can be used under severe conditions, for example, the stainless characteristic is maintained in saline water, sulfur water or halide salt. Moreover, the stainless steel filtering net prepared by using the processing technology has the characteristics of high strength, high filtering precision, simplicity in cleaning and convenience in installation.
Description
Technical field
The present invention relates to a kind of processing technology of stainless steel filtering net.
Background technology
Fore filter is generally arranged on the front end of pipeline, thus with " preposition " two word name; And " filtration ", then refer to the general principle of this kind equipment.Be generally T-shape structure.The two ends, left and right, position of " one is horizontal " are above respectively intake-outlet." one erects " position is below fuselage and inner cylindrical filter sieve, is then sewage draining exit bottom, controls to open and close by a valve.After fore filter is arranged on inlet channel water meter usually, to guarantee that a large amount of precipitated impurities produced in pipe network can not damage human body, and positive protective effect is played to concealed pipe, tap, electrical equipment etc.Fore filter is the jinx of secondary pollution, is a kind of device for filtering impurities reliably.Domestic type fore filter is the first coarse filtration equipment to full room water, can silt in Filtered tap water, iron rust, large particulate matter.
The accuracy rating of fore filter filter screen is not according to different brands and model from 5-300 micron etc., the granule foreign that the precipitated impurities that main removal pipeline produces and bacterium, microorganism remains, iron rust, husky mud etc. are greater than more than 5 microns, avoids human body and skin to come to harm; And positive protective effect is played to downstream line, water purifier, water heater, washing machine, high-grade tap, flower Samburu.
Existing filter screen is generally stainless steel, because long moist environment makes stainless steel not corrosion-resistant.
Summary of the invention
For solving the problems of the technologies described above, the invention provides that a kind of intensity is high, filtering accuracy is more accurate and being easy to the processing technology of the stainless steel filtering net cleaning and install.
The processing technology of a kind of stainless steel filtering net of the present invention, step is:
1) choosing stainless wire mesh is raw material, by high-accuracy braider, material knitting is become stainless (steel) wire;
2) by step 1) stainless (steel) wire after establishment is cut into the rectangle mesh sheet of required filter screen size;
3) by step 2) mesh sheet four limit after cutting carries out finish trimming, removes burr;
4) by step 3) mesh sheet after finish trimming is put on fixed mould, utilizes the method for manual electric arc welding that mesh sheet is welded into net cylinder;
5) by step 4) weld seam on the net cylinder that welds heat-treats;
6) by step 5) net cylinder after heat treatment puts into Ultrasonic Cleaning pond and cleans, and obtains stainless steel filtering net.
Further, described raw material is for containing molybdenum stainless steel.
Further, described raw material is 316L stainless wire mesh.
Further, described stainless (steel) wire is double-deck plain weave stainless (steel) wire.
Further, described step 5) heat-treat condition for be warming up to more than 950 DEG C in 30s, and be incubated 30s; Then to quench 120s with quenching liquid; Tempering; Be down to room temperature.
The processing technology of a kind of stainless steel filtering net of the present invention adopts containing molybdenum 316L stainless steel, owing to the addition of molybdenum element in this stainless steel, make it have good corrosion resistance, atmospheric corrosion resistance and resistance to elevated temperatures, can use under severe cruel condition, as kept its stainless property in salt solution, sulphur water or halogen; The stainless steel filtering net using this processing technology to prepare has that intensity is high, filtering accuracy is more accurate, is easy to clean and feature easy for installation.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
A processing technology for stainless steel filtering net, step is:
