Abstract
The utility model relates to a deep-filtration stainless steel powder sintering filter element which consists of a stainless steel powder sintering filter element, a joint, a transition joint and a metal powder coating. In sintering, the stainless steel powder sintering filter element and the transition joint are fused into an integrated structure, and the joint is welded on the transition joint; due to high strength, the integrated structure is not easily broken when in use, and the broken impurities are effectively prevented from falling into the filtered material; the metal powder coating is sprayed onto the surface of the stainless steel powder sintering filter element, and the coating structure is an effective filtering layer with wall thickness of 0.2mm, which is sprayed onto a porous metal sintering filter element with large pore diameter and wall thickness of 2mm; since the coating technology adopts large-pore diameter particles as a support body, the real thickness of the filtering layer is only 0.2mm, the filtering pressure drop is effectively reduced, the flux of the filter element is increased, the back-flushing regeneration effect is optimized, and the absolute filtering precision is improved; the deep-filtration stainless steel powder sintering filter element provided by the utility model has the advantages of long service life, high filtering efficiency and the like.
Description
Technical field:
The utility model relates to a kind of filter core, relates in particular to a kind of in-depth filtration powder of stainless steel sintered filter core.
Background technology:
The powder of stainless steel sintered filter core has advantages such as mechanical strength height, high temperature resistant, corrosion-resistant, good permeability and is widely used in liquid or the pneumatic filter because of it, be used for removing gas or liquid type granule foreign.But under the more operating mode of impurity, existing powder of stainless steel filter core, it is low to recycle rate, blocks easily under the more situation of impurity; Structure as shown in Figure 1, after joint (10) and transit joint (20) welding, be welded on again on the filter core (30), influenced by temperature and welding procedure, this structure in use causes transit joint (20) to fracture easily, material after causing filtering is defective, and the service life of filter core (30) is not long yet.
Summary of the invention:
The utility model provides the in-depth filtration powder of stainless steel sintered filter core of a kind of filter efficiency height, long service life.
For realizing the above object, the technical solution adopted in the utility model is:
In-depth filtration powder of stainless steel sintered filter core is made up of powder of stainless steel sintered filter core, joint, transit joint, metal dust coating; It is characterized in that: the metal dust coating spraying is on the surface of powder of stainless steel sintered filter core, transit joint and the powder of stainless steel filter core formula structure that is sintered into one, and joint is welded on the transit joint.
The technical problem that the utility model patent solves is:
1. in the surperficial spray metal of powder of stainless steel sintered filter core powder coating, this coating structure is to be that porous metals sintered filter core spraying one deck wall thickness of the larger aperture of 2mm is effective filter course of 0.2mm at wall thickness, coating technology is owing to adopt gross porosity footpath particle as supporter, real filter course thickness only is 0.2mm, the filtration pressure drop effectively reduces, strengthen the flux of filter core, optimized the pulse cleaning effect, improved absolute filtering accuracy.
2. when the sintered stainless steel powder filter element, powder of stainless steel sintered filter core and transit joint are merged in one, compare with traditional welding procedure, this integral structure is because of its higher intensity, frangibility not in use, impurity after effectively having avoided fractureing dissolves in the material after the filtration, has prolonged the service life of filter core simultaneously.
Description of drawings:
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is the decomposing schematic representation of prior art;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is decomposing schematic representation of the present utility model
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment; As shown in the figure, in-depth filtration powder of stainless steel sintered filter core is made up of powder of stainless steel sintered filter core 3, joint 1, transit joint 2, metal dust coating 4.
During sintering, powder of stainless steel sintered filter core 3 and transit joint 2 are merged in one, make its formula structure that is integrated, again that the client is required joint 1 is welded on the transit joint 2, compare with traditional welding procedure, this integral structure is because of its higher intensity, in use frangibility not, impurity after avoiding fractureing dissolves in the material after the filtration, reaches the purpose that increases the service life equally; In the surperficial spray metal of powder of stainless steel sintered filter core 3 powder coating 4, this coating structure is to be that porous metals sintered filter core spraying one deck wall thickness of the larger aperture of 2mm is effective filter course of 0.2mm at wall thickness, coating technology is owing to adopt gross porosity footpath particle as supporter, real filter course thickness only is 0.2mm, the filtration pressure drop effectively reduces, strengthen the flux of filter core, optimized the pulse cleaning effect, improved absolute filtering accuracy.
The utility model patent has advantages such as filter efficiency height, long service life, has market popularization value.
