Abstract
The invention discloses an improvement structure for sealing a filter. The filter comprises a filter core and a frame, wherein the filter core is fixed in the frame; and the filter further comprises an organic silica gel and inorganic ceramic glue. The inorganic ceramic glue is fixedly filled in an interval between the filter core and the frame in a sealing manner, a layer of organic silica gel further covers the outer side surface of the inorganic ceramic glue in a sealing manner, and the organic silica gel is fixedly connected with the frame and the filter core in the sealing manner. The invention utilizes a double-sealing structure of covering the organic silica gel on the outer side of the inorganic ceramic glue in a sealing manner, and utilizes the advantages of the organic silica gel and the inorganic ceramic glue to ensure that the filter does not leak when being used at high temperature; simultaneously, the dust generation of the filter is further avoided, and downstream technical environment is protected from being polluted.
Description
Technical field
The present invention relates to a kind of filter hermetically-sealed construction, especially a kind of structure-improved of filter sealing.
Background technology
The high temperature high efficiency filter is made up of framework, filter core, fluid sealant; Its framework is main with stainless steel, and filter core adopts high temperature resistant filter paper, and the main fluid sealant that leans on of sealing is accomplished; Fluid sealant plays a part fixedly filter core and sealing; Fluid sealant commonly used is main with resistant to elevated temperatures organic silica gel and inorganic ceramic glue, also has some high temperature high efficiency filters not use the fluid sealant sealing, fills in filler between filter core and the framework with sealing but be employed in.
When using organic silica gel to seal, the viscosity of organic silica gel has very big influence to sealing effectiveness, if thickness too then is unfavorable for production operation, is prone to leak, and influences properties of product and production efficiency.
When using the sealing of inorganic ceramic glue; Because self expand with heat and contract with cold, the surface can produce the crack to inorganic ceramic glue, and can break away from stainless steel frame after intensification; Owing to the material behavior of inorganic ceramic glue itself, inorganic ceramic glue surface after intensification can produce some fine dusts simultaneously.The crack can cause product leakage, and dust can cause the pollution of filter air downstream.
When using the packing material sealing, normally clog filter paper, owing to be difficult to the uniformity and the packing of control packing material; The filter of producing is very difficult through test, even pass through test before heating up, after intensification; Because the distortion of encapsulant also is easy to cause leakage.
Summary of the invention
In order to overcome above-mentioned defective, the present invention provides a kind of structure-improved of filter sealing, and the structure-improved of this filter sealing can play the double action that not only prevents to produce dirt but also prevent heads.
The present invention is in order to solve the technical scheme that its technical problem adopts: a kind of structure-improved of filter sealing, and filter comprises filter core and framework, said filter core is fixedly arranged in the framework; Also comprise organic silica gel and inorganic ceramic glue, said inorganic ceramic glue sealing and fixing is filled in the gap between filter core and the framework, and said inorganic ceramic glue outer surface also seals and is coated with one deck organic silica gel; This organic silica gel and framework and filter core sealing are connected, and when assembling sealing for the first time, adopt the sealing of inorganic ceramic glue between framework and filter core; Inorganic ceramic glue has good temperature tolerance; And be easy to production operation, after the inorganic ceramic adhesive curing, seal for the second time with organic silica gel again; The product dirt that so both can stop inorganic ceramic glue effectively; Owing to have very strong caking property between organic silica gel and the stainless steel, can prevent that inorganic ceramic glue and framework break away from the generation crack, play the double action that not only prevents to produce dirt but also prevent heads simultaneously.
As further improvement of the present invention, said organic silica gel is positioned at the inorganic ceramic glue outer surface of filter air intake surface, when guaranteeing sealing like this, saves material.
The invention has the beneficial effects as follows: the present invention is employed in the double sealing structure that the outer side seal of inorganic ceramic glue is coated with machine silica gel, utilizes the advantage separately of organic silica gel and inorganic ceramic glue, when guaranteeing that filter at high temperature uses, does not produce leakage; Also avoided the product dirt of filter simultaneously, protection downstream process environment is not contaminated.

The specific embodiment
Embodiment: a kind of structure-improved of filter sealing, filter comprises filter core 1 and framework 2, said filter core is fixedly arranged in the framework; Also comprise organic silica gel 3 and inorganic ceramic glue 4, said inorganic ceramic glue 4 sealing and fixing are filled in the gap between filter core 1 and the framework 2, and said inorganic ceramic glue 4 outer surfaces also seal and are coated with one deck organic silica gel 3; 1 sealing is connected this organic silica gel 3 with filter core with framework 2, and when assembling sealing for the first time, 1 of framework 2 and filter core adopt 4 sealings of inorganic ceramic glue; Inorganic ceramic glue 4 has good temperature tolerance; And be easy to production operation, after inorganic ceramic glue 4 solidifies, again with organic silica gel 3 sealing for the second time; The product dirt that so both can stop inorganic ceramic glue 4 effectively; While can prevent that inorganic ceramic glue 4 and framework 2 break away from the generation cracks, play the double action that not only prevents to produce dirt but also prevent heads owing to have very strong caking property between organic silica gel 3 and the stainless steel.
Said organic silica gel 3 is positioned at inorganic ceramic glue 4 outer surfaces of filter air intake surface, when guaranteeing sealing like this, saves material.
