Flow smoothing device for spraying glaze on immersion bell and immersion bell glaze sprayer

Abstract

The invention relates to a flow smoothing device for spraying glaze on an immersion bell, which is characterized by comprising a flow smoothing arc-shaped plate (1), wherein two hems bent outwards are arranged on one arc-shaped edge of the flow smoothing arc-shaped plate (1), two hems are flow smoothing lug arms (2), and a flow smoothing notch (3) which is lower than the highest end surface of the two flow smoothing lug arms is formed between the two flow smoothing lug arms (2). In the flow smoothing device provided by the invention, as the flow smoothing lug arms on two edges are higher thanthe flow smoothing notch, the glaze flow rate is smaller, but the flow rate of the glaze flowing through the flow smoothing notch is bigger so as to form a thicker sector glaze curtain; after the glaze flowing out of the flow smoothing notch and the glaze flowing through the flow smoothing lug arms simultaneously flow downwards and are mixed, the glaze flowing out of the flow smoothing notch is thinned, and the uniform glaze curtain is further formed on the immersion bell.

Description

Technical field [0001] The invention relates to an advection device for glazing a bell jar, in particular to a glazing device for realizing a uniform and stable glazing curtain for a bell jar, and an advection device for making the glaze material on the surface of a brick after glazing uniform; The bell jar glazer of the above-mentioned advection device. Background technique [0002] In the ceramic industry, most manufacturers use the bell jar glazing process to glaze the bricks. Since the bell jar glazer is arc-shaped, the glaze can apply pressure to each point of the bricks evenly through the arc-shaped cover, and the difference in glaze weight is small. , the quality of the glazed surface finally obtained is high; in actual production, the part of the bell jar parallel to the glaze line is generally used for glaze production, that is, two wet cloth strips are used to form a fan on the surface of the bell jar glaze applicator, and the glaze is drawn from the bell jar. The...

AI Technical Summary

Problems solved by technology

When glazing, the glaze in the middle part of the brick is relatively thin, and the water is collected quickly. The glaze flows to the four sides and accumulates under the action of gravity, resulting in a thicker glaze layer on the four sides of the brick, and slow water collection, especially in the direction parallel to the glaze line. The glaze layer on the edge of the brick is thicker and the water is collected more slowly, so that more glaze is poured on both sides of the brick than in the middle, resulting in uneven glaze, prone to "heavy glaze" defects, and it is easy to cause the brick when using roller printing. "Color streaks" appear on both sides of the surface; when producing colored glaze, the glaze on both sides is thicker than the middle, resulting in the color of the edge being darker than the middle, forming a "color edge"

When producing special-shaped adobes with thin edges and thick middle, there will be too much glaze on both sides, resulting in flowing glaze, which not only causes waste of glaze, but also easily causes edge collapse due to glaze droplets absorbed by the edges of the adobe , peeling glaze defects, seriously affecting the quality of the product
