A self-tightening device for cleaning atmospheric pressure storage tanks

Abstract

A self-tightening device used for normal-pressure storage tank sweeping aims at solving the problems that potential safety hazards exist in existing normal-pressure storage tank sweeping holes, the normal-pressure storage tank sweeping holes are not suitable for refitting or extension, devices are too heavy, a large number of resources are occupied, and cost is high. The self-tightening device comprises a top plate, a baffle, a sealing base plate and side plates, wherein the top plate covers the upper ends of the two side plates, the joints of the top plate and the side plates are sealed, and an insertion groove is sealed in and fixedly connected with each side plate. The two insertion grooves are formed in the vertical direction. The notches of the two insertion grooves are oppositely formed and parallel to each other. One side of the sealing base plate and the side face of the top plate are sealed and fixedly connected. The lower end of the sealing base plate is sealed together with and fixedly connected with the baffle and the upper ends of the insertion grooves. A baffle hole is formed in the sealing base plate. The baffle penetrates through the baffle hole. The two sides of the baffle penetrate through the two insertion grooves respectively. The baffle, the sealing base plate and the two insertion grooves are sealed. The self-tightening device is used for storage tank sweeping.

Description

technical field [0001] The invention relates to a self-tightening device, in particular to a self-tightening device for an atmospheric storage tank. Background technique [0002] In industrial production, such as the production of alumina, there are many processes in which there is a suspension of solid particles and solutions. These suspensions need to be equipped with a large number of atmospheric storage tanks with cleaning holes for storage. The conventional cleaning holes used in the current project are composed of cleaning hole bottom plate, reinforcing plate, column, reinforcement plate, beam, nut, hexagon head screw with hole nut, washer, cotter pin, adjusting bolt, lifting lug, bolt, seamless steel pipe , steel plate, flange, gasket, flange cover and other seventeen parts. Among them, there are as many as 60 nuts and bolts, three ribs, and one piece for the rest. The conventional cleaning hole is welded to the bottom and wall of the tank, and bolts, nuts and gaske...
