Abstract

The invention relates to a sealing structure for enamel reaction kettles.The sealing structure comprises a bearing box with a first through hole formed in the bottom, a first shaft sleeve is rotatably arranged on the inner side of the first through hole and made of ceramic or silicon carbide, and a plurality of bushing rings arranged at intervals are fixed in the first through hole in a matched mode; an elastic sealing lip piece is arranged between every two adjacent bushing rings, each sealing lip piece comprises an annular body, a lip opening part is arranged on the inner side of each annular body, the annular bodies are fixed between the inner side end faces of the adjacent bushing rings in a matched mode, and the lip opening parts are attached to the outer side of the first shaft sleeve and bent in an arc shape. The novel sealing structure is good in sealing performance, a gas supply or liquid sealing system does not need to be used, the part in contact with materials is made of corrosion-resistant non-metal materials, and the novel sealing structure can tolerate more chemical media.

Description

technical field [0001] The invention relates to the technical field of reaction kettles, in particular to a sealing structure for an enamel reaction kettle. Background technique [0002] The enamel reaction kettle includes a stirring shaft. The sealing sleeve on the stirring shaft is provided with a shaft sleeve. The shaft sleeve is rotatably arranged in the bearing box. To ensure the tightness between them, it is usually necessary to use an air supply or sealing liquid system, which has a complicated sealing structure and high cost. Contents of the invention [0003] The technical problem to be solved by the present invention is a sealing structure for an enamel reaction kettle. Accept more chemical media. [0004] In order to solve the above-mentioned technical problems, the present invention provides a sealing structure for an enamel reaction kettle, which includes a bearing housing with a first through hole at the bottom, a first shaft sleeve is arranged on the inner...
