Embodiment Construction

[0025] In order to deepen the understanding and recognition of the present invention, the present invention will be further described and introduced below in conjunction with the accompanying drawings.

[0026] Such as figure 1 — Figure 8 As shown, a filter element includes an outer cover 1, an inner cover 5, a stainless steel sealing plate 3 and a stainless steel filter screen 2, and the surface roughness of the removed processing surface of the outer cover 1, the inner cover 5 and the stainless steel sealing plate 2 must not exceed the maximum More than 6.3 microns, with the inner sleeve 5 as the skeleton of the stainless steel filter screen 2, the length of the stainless steel filter screen 2 is consistent with the inner sleeve 5, but the inner diameter of the stainless steel filter screen 2 is slightly larger than the outer diameter of the inner sleeve, so the stainless steel filter screen 2 Put it on the inner sleeve 5, and then use the outer sleeve 1 to cover the stain...

Abstract

The invention relates to a filter element which comprises an outer sleeve, an inner sleeve, a stainless steel sealing plate and a filter screen, wherein the inner sleeve is used as a support frame of the filter screen, the filter screen is connected onto the inner sleeve in a sleeving manner, the outer sleeve is connected onto the filter screen in a sleeving manner for tightly pressing the filter screen, the outer sleeve is connected with the inner sleeve through welding, the stainless steel sealing plate is welded at one side of the outer sleeve, welding grooves are formed in the outer sleeve, inner sleeve and the stainless steel sealing plate, so as to facilitate welding and splicing, and the filter screen adopts a 50-mesh double-layer stainless steel filter screen. The filter element provided by the invention is wholly made of a stainless steel material, the filter screen is fixed through the outer sleeve and the inner sleeve, the stainless steel sealing plate is adopted at the bottom of the filter element for blocking and welding is applied, so that the whole pressure resistance of the filter element is improved, and the filter element has the advantages that the structure is simple and reliable, the processing is simple, the manufacturing cost is low, the use and replacement are convenient, the service life is long, the storage is convenient and the like, and is easy to popularize.

Description

[0001] technical field [0002] The invention relates to a filter element, in particular to a Y-shaped filter element used in a steel continuous casting cooling water system. Background technique [0003] The quality of the filter element of the Y-type filter used in the steel continuous casting cooling water system directly affects the filtering effect of the cooling water. The structural form of the filter element used in the existing Y-type filter is not perfect. Due to the influence of the water pressure in the cooling water system, the existing filter element often shrinks and deforms. In order to ensure the filtering effect of the cooling water, frequent Replacing the filter element results in high production costs and greatly reduces production efficiency. When the deformed filter element is not found and replaced in time, it will lead to blockage of cooling nozzles in the active section of steel continuous casting, resulting in uneven cooling of the billet, which wi...
