Problems solved by technology

[0002] The switching of the bypass flue gas under the heat preservation condition of the existing Austrian furnace and electric furnace is realized through the bell valve. Due to the high temperature of the Austrian furnace and the electric furnace, the switching process needs to be realized through an automatic control system. The practical patent No. 97228308.0 The new patent discloses a starting bell valve, the bell valve realizes the automatic opening and closing of the bell through the pneumatic valve stem, but the degree of opening and closing of the bell cannot be precisely controlled, which may easily cause leakage of the bell valve, etc.

Abstract

The invention discloses a bell valve self-lifting system and a working method thereof. The bell valve self-lifting system comprises a triangular support; a hydraulic oil cylinder is fixed to the triangular support; the hydraulic oil cylinder is connected with a high pressure cylinder intelligent controller; the high pressure cylinder intelligent controller is connected with a PLC control system; avertically distributed suspension rod is connected and fixed to the power output end of the hydraulic oil cylinder; a plurality of first fixing blocks are uniformly distributed at the bottom end of the triangular support at equal angles; a top cover is fixedly arranged at the bottom ends of the first fixing blocks by screws; a packing sealing box is fixedly arranged at the middle part of the topend of the top cover; one end, of the suspension rod penetrates through the packing sealing box and the top cover, and is sleeved with and is fixedly provided with a connecting seat; and the outer surface of the side wall of the connecting seat is connected with a bell through a plurality of suspension chains distributed equidistantly. The extension and contraction of the hydraulic oil cylinder isprecisely controlled through the PLC control system, so that accurate control on the opening-closing degree of a bell valve is realized, the opening of the bell valve can be displayed on a computer during remote control, the sealing effect between the bell and a bell seat is good, and thus smoke can be effectively prevented from entering the bell valve.

Description

technical field [0001] The invention belongs to the field of dust collection, and relates to a bell valve automatic lifting system and a working method thereof. Background technique [0002] The switching of the bypass flue gas under the heat preservation condition of the existing Austrian furnace and electric furnace is realized through the bell valve. Due to the high temperature of the Austrian furnace and the electric furnace, the switching process needs to be realized through an automatic control system. The practical patent No. 97228308.0 The new patent discloses an actuating bell valve. The bell valve realizes the automatic opening and closing of the bell through the pneumatic valve stem, but the degree of opening and closing of the bell cannot be precisely controlled, which may easily cause leakage of the bell valve. Contents of the invention [0003] The object of the present invention is to provide a bell jar valve automatic lifting system and its working method. ...
