Abstract
The utility model discloses an improved structure for sealing a filter. The filter comprises a filter core and a frame, wherein the filter core is fixedly arranged inside the frame; the filter further comprises organic silica gel and inorganic ceramic gel, wherein the inorganic ceramic gel is fixedly filled inside the gap between the filter core and the frame in a sealing way; the surface of the outer side of the inorganic ceramic gel is sealed and covered with a layer of organic silica gel; and the organic silica gel is connected with the frame and the filter core in a sealing way. By adopting a dual-sealing structure that the outer side of the inorganic ceramic gel is sealed and covered with the organic silica gel and by taking advantages of the organic silica gel and the inorganic ceramic gel, the liquid leakage is avoided when the filter is used at a high temperature; and meanwhile, the dust formation of the filter is avoided and the downstream process is protected from environmental pollution.
Description
Technical field
The utility model 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 based on stainless steel, filter core adopts high temperature resistant filter paper, sealing is mainly finished by fluid sealant, fluid sealant plays a part fixedly filter core and sealing, fluid sealant commonly used also has some high temperature high efficiency filters not use the fluid sealant sealing based on resistant to elevated temperatures organic silica gel and inorganic ceramic glue, fills in filler with sealing between filter core and framework but adopt.
When using organic silica gel to seal, the viscosity of organic silica gel has a significant impact sealing effectiveness, if thickness too then is unfavorable for production operation, easily leaks, 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 can produce some fine dusts in the intensification rear surface 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 by test, even pass through test before heating up, after intensification, because the distortion of encapsulant also is easy to cause leakage.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of structure-improved of filter sealing, and the structure-improved of this filter sealing can play and not only prevent the double action of producing dirt but also preventing to leak.
The utility model is in order to solve the technical scheme that its technical problem adopts: a kind of structure-improved of filter sealing, filter comprises filter core and framework, described filter core is fixedly arranged in the framework, also comprise organic silica gel and inorganic ceramic glue, described inorganic ceramic glue sealing and fixing is filled in the gap between filter core and the framework, described 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, 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, so both can stop the product dirt of inorganic ceramic glue effectively, simultaneously owing to have very strong caking property between organic silica gel and the stainless steel, can prevent that inorganic ceramic glue and framework from break away from producing the crack, play and not only prevent the double action of producing dirt but also preventing to leak.
As further improvement of the utility model, described 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 beneficial effects of the utility model are: the utility model employing side seal outside inorganic ceramic glue is coated with the double sealing structure of 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, described filter core is fixedly arranged in the framework, also comprise organic silica gel 3 and inorganic ceramic glue 4, described inorganic ceramic glue 4 sealing and fixing are filled in the gap between filter core 1 and the framework 2, described inorganic ceramic glue 4 outer surfaces also seal and are coated with one deck organic silica gel 3, this organic silica gel 3 is connected with framework 2 and filter core 1 sealing, 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, with organic silica gel 3 sealing for the second time, so both can stop the product dirt of inorganic ceramic glue 4 effectively, more simultaneously owing to have very strong caking property between organic silica gel 3 and the stainless steel, can prevent that inorganic ceramic glue 4 breaks away from framework 2 produces cracks, plays and not only prevents the double action of producing dirt but also preventing to leak.
Described 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.
