Dual-sealing mechanism for tank cover of aluminum melt degasification tank

Abstract

The invention discloses a dual-sealing mechanism for a tank cover of an aluminum melt degasification tank. The dual-sealing mechanism comprises an inner sealing strip, an outer sealing strip, wrappingcloth and an L-shaped part, wherein the outer sealing strip is away from a furnace chamber of the degasification tank relative to the inner sealing strip; the inner sealing strip and the outer sealing strip are wrapped with the wrapping cloth; the L-shaped part comprises a first flat plate and a second flat plate which are in vertical butted joint, the first flat plate is connected and fixed witha batten, so that the inner sides of the wrapping cloth are attached, the inner sealing strip and the outer sealing strip are separated to constitute a clearance groove, the batten is located at thebottom of the clearance groove, and the second flat plate is connected and fixed with the tank cover; channel steel is fixed on the tank cover and comprises a third flat plate and a fourth flat platewhich are parallel to each other, a fifth flat plate is vertically connected between the third flat plate and the fourth flat plate, a nut is fixed on the fourth flat plate, and a through hole coaxialwith the nut is formed in the fourth flat plate; a cushion block is fixed on the third flat plate. With the adoption of the dual-sealing mechanism, the thermal insulation effect of the tank cover isimproved, and the sealing strips are convenient to dismount and mount and are connected stably after being mounted.

Description

technical field [0001] The invention relates to the field of furnace door sealing, in particular to a double sealing mechanism for the cover of an aluminum melt degassing box. Background technique [0002] The main function of the aluminum melt degassing box is to reduce the hydrogen content in the aluminum melt. It must achieve constant temperature and sealing conditions during work. The sealing between the box body and the furnace cover becomes the key to the operation of the equipment. Failure to do so well will affect the normal operation of the equipment. Contents of the invention [0003] The problem to be solved by the present invention is to provide a double sealing mechanism for the cover of the aluminum melt degassing box, which improves the heat insulation effect of the cover, the sealing strip is easy to disassemble, and the connection is stable after installation. [0004] In order to solve the above problems, the present invention provides a double sealing m...
