Problems solved by technology
Cracks can cause product leakage and dust can cause air pollution downstream of the filter
[0005] When sealing with filling material, filter paper is usually stuffed. Because it is difficult to control the uniformity and compactness of the filling material, it is difficult for the produced filter to pass the test. Even if it passes the test before heating up, after heating up, due to the deformation of the sealing material, It is also easy to cause leakage

Embodiment
[0014] Embodiment: An improved structure for filter sealing, the filter includes a filter core 1 and a frame 2, the filter core is fixed in the frame, and also includes organic silica gel 3 and inorganic ceramic glue 4, and the inorganic ceramic glue 4 is sealed and fixed for filling In the gap between the filter element 1 and the frame 2, the outer surface of the inorganic ceramic glue 4 is sealed and covered with a layer of organic silica gel 3, and the organic silica gel 3 is sealed and fixed with the frame 2 and the filter element 1. , the frame 2 and the filter element 1 are sealed with inorganic ceramic glue 4, which has good temperature resistance and is easy to produce and operate. After the inorganic ceramic glue 4 is solidified, it is sealed with organic silica gel 3 for the second time, so that It can effectively prevent the dust production of the inorganic ceramic glue 4, and at the same time, due to the strong adhesion between the organic silica gel 3 and the stain...

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 [0001] The invention relates to a filter sealing structure, in particular to an improved filter sealing structure. Background technique [0002] The high-temperature-resistant high-efficiency filter is composed of a frame, a filter element and a sealant. The frame is mainly made of stainless steel. The filter element is made of high-temperature-resistant filter paper. The sealing is mainly completed by the sealant. High temperature resistant organic silica gel and inorganic ceramic glue are the main ones, and some high temperature resistant high efficiency filters do not use sealant to seal, but use fillers between the filter element and the frame to seal. [0003] When using silicone for sealing, the viscosity of the silicone has a great impact on the sealing effect. If it is too thick, it is not conducive to production operations, easy to leak, and affects product performance and production efficiency. [0004] When the inorganic ceramic glue is used for s...
