Description

Blowing adjustable liquid accumulation plate and roller coater

Technical Field

The utility model belongs to the technical field of belted steel roller coat equipment, concretely relates to jetting adjustable hydrops dish and roller coat machine.

Background

The horizontal 2-roller roll coater applied to the oriented silicon steel MgO coating generally consists of 1 upper coating roller, 1 lower coating roller, a spraying and liquid supplying device of the upper coating roller, a liquid supplying disc of the lower coating roller and a liquid accumulating disc. The MgO coating liquid is pumped out of the MgO coating liquid circulating tank by a supply pump, is sprayed out through a spray pipe arranged at the inlet of the upper coating roller, is dispersed on the strip steel at the inlet of the upper coating roller, is extruded and uniformly distributed on the strip steel when passing through the upper coating roller, and forms a uniform coating on the upper surface of the strip steel; and excessive coating liquid in the spray pipe partially overflows into a liquid supply disc of the lower coating roller, the lower coating roller is partially immersed in MgO coating liquid in the liquid supply disc, the coating liquid is brought to a contact angle between the strip steel and the coating roller in the rotating process of the lower coating roller, and a locally uniform MgO coating is formed on the lower surface of the strip steel through the rotating extrusion of the lower coating roller. The lower part of the coating machine is provided with a large liquid accumulation disc for collecting excessive coating liquid supplied by spraying, coating liquid supplied by the supply disc and overflowing, and part of splashed coating liquid, and the collected coating liquid overflows from the bottom of the liquid accumulation disc back to the MgO coating liquid circulating tank to form a coating liquid circulating loop.

However, the MgO coating liquid is a suspension of MgO particles dispersed in water, and when the coating liquid is static or has a slow flow rate, the MgO particles may be deposited, and the coating liquid reflowing or splashed to the liquid accumulation plate may continuously deposit MgO around the liquid accumulation plate. A very thick MgO deposition layer is formed in a production period (from the time when a new coating roller is put into production to the time when the coating roller is stopped for replacement), and the MgO deposition layer is very compact due to the small particle size, so that the difficulty in cleaning the deposition layer is huge.

At present, an effective MgO deposition layer cleaning method is manual removal, but the roller coater has a compact structure and compact MgO scaling, so that the labor intensity is high and the labor environment is severe. In addition, the MgO deposition also reduces the utilization efficiency of the MgO coating liquid.
