Abstract
The invention discloses a fabricating method of a block net type candle filter element, which comprises the following steps of fabricating a filter element framework, fabricating a filtering net, assembling and forming, and the like. The invention has convenient fabrication, good fabrication effect, reasonable fabricated product and good working property.
Description
Technical field:
The present invention relates to a kind of fabricating method of block net type candle filter element.
Background technology:
Block net type candle filter element is the filtration critical component on the big flow full-automatic back washing oil screen peculiar to vessel.The filter core that existing manufacture method is made, service behaviour is undesirable, makes complicated.
Summary of the invention:
The object of the present invention is to provide a kind of easily manufactured, block net type candle filter element that manufacturing effect is good.
Technical solution of the present invention is:
A kind of fabricating method of block net type candle filter element is characterized in that: comprise the following steps:
(1) makes frame of filter element: the stainless steel wire of six roots of sensation Φ 2 and the circular joint at two ends are welded by even six five equilibriums, laterally the stainless steel wire with Φ 0.8 is centered around on the above-mentioned six roots of sensation steel wire with helical form, and with the horizontal and vertical equal firm welding of each contact point, skeleton diameter after the welding is Φ 27mm, deviation from cylindrical form≤0.8mm;
(2) make screen pack: adopt the mesh grid of 316L stainless steel material, being rolled into diameter is the cylindrical of Φ 27mm, and vertically in lap-joint's firm welding, weld seam is controlled in the scope of 2～2.5mm;
(3) assembling moulding: with frock with frame of filter element along the circumference radial contraction, screen pack is inserted in frame of filter element, load onto big envelope then respectively at the filter core two ends, close up fixing.
Before the assembling, also frame of filter element is adopted freezing processing in the step (3).
The present invention is easily manufactured, manufacturing effect good, and the product structure of manufacturing is reasonable, favorable working performance.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of the block net type candle filter element made of the present invention.
The specific embodiment:
A kind of fabricating method of block net type candle filter element comprises the following steps:
(1) makes frame of filter element: the stainless steel wire 2 of six roots of sensation Φ 2 and the circular joint 6,7 at two ends are welded by even six five equilibriums, laterally the stainless steel wire 4 with Φ 0.8 is centered around on the above-mentioned six roots of sensation steel wire with helical form, and with the horizontal and vertical equal firm welding of each contact point, skeleton diameter after the welding is Φ 27mm, deviation from cylindrical form≤0.8mm;
(2) make screen pack: adopt 316L stainless steel material mesh grid 3, being rolled into diameter is the cylindrical of Φ 27mm, and vertically in lap-joint's firm welding, weld seam is controlled in the scope of 2～2.5mm;
(3) assembling moulding: frame of filter element is adopted freezing shrink process, and with frock with frame of filter element along the circumference radial contraction, screen pack is inserted in frame of filter element, load onto big envelope 1,5 then respectively at the filter core two ends, close up fixing.Get product.
Claims (2)
