a cover

Abstract

The invention discloses a sealing cover. The sealing cover is a shell structure combined by an outer cover plate, an inner cover plate, a left cover plate, a right cover plate, an upper cover plate and a lower cover plate; notches with symmetric center lines are formed in the outer cover plate; the notches upwards extend above the center of the outer cover plate from the lower end of the outer cover plate; the inner cover plate is divided into a first inner plate and a second inner plate arranged left and right; the first inner plate is as wide as the second inner plate, and the widths of the first inner plate and the second inner plate are equal to the width of one sides of the notches of the outer cover plate; two arc grooves outwards recessed are respectively formed in the opposite inner sides of the first inner plate and the second inner plate; two opposite arc grooves form a circular area; and the circular area is larger than the circle area at the end of a wiping roller shaft. The sealing cover is used for sealing a mounting groove in an acid washing tank, so that the cleaning effect of the acid washing tank on steel strips is improved, and the acid washing cost is saved; and the sealing cover has the advantages of low mass and easiness in disassembly.

Description

technical field [0001] The invention relates to the technical field of pickling equipment for steel strip pickling lines, in particular to a cover. Background technique [0002] On the steel strip pickling production line, after the steel strip enters the pickling tank for cleaning, it passes out from the pickling tank. In order to prevent the surface of the steel strip passing out of the pickling tank from having a large amount of pickling liquid, the steel strip is squeezed once by means of a squeeze roller arranged on the pickling tank before the steel strip passes out of the pickling tank. dry operation. [0003] The squeeze roller consists of a pair of upper shaft rollers and lower shaft rollers arranged in parallel. The steel strip passes between the upper shaft rollers and the lower shaft rollers and is squeezed to a certain extent, so as to remove the pickling solution attached to the surface of the steel strip. Dry. With the increase of the use time, the wear of ...

AI Technical Summary

Problems solved by technology

[0004] At present, on the existing pickling tank equipment, by setting up an installation groove on both sides of the pickling tank, the squeezing roller is installed in the installation groove after being matched with the bearing seat, and the installation groove is connected with the pickling tank and It is not closed, so that part of the pickling liquid will flow out of the pickling tank along the axial direction of the squeeze roller, resulting in waste of pickling liquid; especially when the steam scrubbing function is added to the pickling tank of some pickling production lines , the steam is particularly easy to overflow from the installation tank, affecting the cleaning temperature in the pickling tank and affecting the cleaning effect

[0005] In short, in the existing pickling tank equipment, the installation tanks on the pickling tanks at both ends of the squeeze roller are open, which affects the cleaning effect of the pickling tank on the steel strip or increases the pickling cost on the pickling tank
