Vacuum sealing assembly structure of calcining kiln

Abstract

The vacuum sealing assembly structure comprises a furnace body conical barrel, the furnace body conical barrel is rotationally sleeved with a sealing barrel, the end, away from the furnace body conical barrel, of the sealing barrel is covered with a sealing cover, and the end face of the sealing barrel and the sealing cover are jointly annularly provided with sealing bolts at equal intervals; a first sealing ring is fixedly installed on the outer side wall of the end, close to the sealing barrel, of the furnace body conical barrel, the end, close to the furnace body conical barrel, of the sealing barrel is fixedly sleeved with a second sealing ring, and the first sealing ring and the second sealing ring are in sliding contact with each other. By means of negative pressure generated by vacuumizing in the furnace body, sealed rotating connection between the furnace body taper pipe and the sealing cylinder is achieved, the pressure of the furnace body is restored to normal pressure during disassembly, disassembly and assembly operation is more convenient, furnace ash is prevented from entering a rotating gap in a screw-in sealing mode, the sealing performance of rotating connection is improved, and the vacuum degree in the furnace is not affected.

Description

technical field [0001] The invention relates to the technical field of vacuum sealing of calcining kiln, in particular to the vacuum sealing component structure of calcining kiln. Background technique [0002] The existing kiln vacuum sealing components are usually sealed by means of connecting and fixing the rotating connector, that is, the two ends of the rotating connector are respectively connected with the kiln head, kiln tail and furnace body, so that during the rotation of the furnace body, the kiln head and kiln The tail does not rotate, which is convenient for the connection and assembly of the inlet and outlet components. However, the connection between the rotating connector and the furnace body and the kiln head and kiln tail is fixed by bolts. During cleaning and maintenance, disassembly and assembly are more troublesome, and during use, the furnace body The dust generated by the calcination of raw materials is likely to pollute the rotating parts of the rotatin...

AI Technical Summary

Problems solved by technology

[0003]The purpose of the present invention is to solve the problems in the prior art that the fixed connection is not easy to disassemble and the furnace ash is easy to pollute the rotating parts, resulting in the decrease of sealing and rotating performance, which affects the vacuum in the furnace Degree of shortcomings, while the proposed structure of the vacuum-sealed components of the calciner kiln
