The lower end cover 542 is tightly contacted with the inner wall of the kettle 100, so that the material flow at the bottom of the kettle 100 can be prevented from splashing to the lower end cover 542, and the annular cleaning brush 543 is polluted along the gap between the lower end cover 542 and the inner wall of the kettle 100. The annular cleaning brush 543 tightly abuts against the inner wall of the kettle body 100, and in the process that the cleaning disc 540 is driven by the piston rod 530 to move up and down along the inner wall of the kettle body 100, the annular cleaning brush 543 is in contact friction with the inner wall of the kettle body 100 to clean materials on the inner wall of the kettle body 100, so that the cleaning operation of the inner wall of the kettle body 100 is realized. Through the coating of the upper end cover 541 and the lower end cover 542 on the annular cleaning brush 543, in the chemical reaction process, the annular cleaning brush 543 does not contact with the material, so that the adhesion of the material on the annular cleaning brush 543 is reduced, the annular cleaning brush 543 does not cause secondary pollution to the inner wall of the autoclave body 100, and the cleaning effect of easily cleaning the high pressure reaction autoclave is ensured. In one embodiment, the cleaning disc 540 has a plurality of flow guiding holes 544 penetrating the upper cover 541 and the lower cover 542. Through setting up a plurality of water conservancy diversion holes 544, in the chemical reaction process, the material can be through water conservancy diversion hole 544 free flow in the inner chamber of the cauldron body 100, and at cauldron body 100 inner wall washing operation in-process, the material raffinate that sprinkler bead 620 washed the production to cauldron body 100 inner wall also will get into cauldron body 100 bottom through water conservancy diversion hole 544, and then derive via the discharge gate of cauldron body 100, prevent that the material raffinate silts up in cauldron body 100, cause the washing of cauldron body 100 inner wall not thorough, influence the cleaning efficiency of cauldron body 100.

In order to further improve the sealing performance of the upper end cover 541 and the lower end cover 542 for covering the annular cleaning brush 543, in an embodiment, an annular sealing rubber 541a is provided at an edge of the upper end cover 541, and an annular sealing rubber 541a is provided at an edge of the lower end cover 542. Through the arrangement of the annular sealing rubber strips 541a, gaps at the connection positions of the upper end cover 541 and the kettle body 100 and at the connection positions of the lower end cover 542 and the kettle body 100 can be further reduced, materials are prevented from entering the annular cleaning brushes 543 through the gaps at the connection positions of the upper end cover 541 and the kettle body 100 and at the connection positions of the lower end cover 542 and the kettle body 100, the pollution degree of the annular cleaning brushes 543 is small, and the cleaning effect of easily cleaning the high-pressure reaction kettle is ensured.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
