A dipping bath according to the present disclosure includes a body to hold a slurry for dip coating, an inlet installed to flow the slurry from an outside of the body to an inside, and an outlet installed to discharge the slurry from the inside of the body to the outside, and one end of the inlet placed inside the body may be disposed facing a side surface of the body at a distance and may be tilted to a predetermined angle in a direction toward a bottom surface of the body. According to the present disclosure, adjustment of an incidence angle of the slurry flowing into the bath through the inlet may increase a flow rate of the slurry toward the bottom surface, as well as allowing a uniform distribution of solids contained in the slurry circulating through the bath.
1. A dipping bath comprising:
a body to hold a slurry for dip coating;
an inlet installed to flow the slurry from an outside of the body to an inside; and
an outlet installed to discharge the slurry from the inside of the body to the outside,
wherein one end of the inlet placed inside the body is disposed facing a side surface of the body at a distance and is tilted to a predetermined tilting angle in a direction toward a bottom surface of the body so that the slurry moves down along the side surface of the body and then flows from and edge of the bottom surface of the body to a center thereof,
wherein the inlet is installed rotatably to enable adjustment of the predetermined tilting angle,
wherein the bottom surface comprises two inclined planes slanting downwards and meeting at a point at a center of the body such that the body is deeper toward the center, and
wherein the outlet is located at a lowest part of the body where the two inclined planes intersect.
2. The dipping bath according to claim 1 , wherein the inlet penetrates the body.
3. The dipping bath according to claim 2 , wherein the inlet is connected to the side surface of the body.
4. The dipping bath according to claim 1 , wherein the inlet comprises a plurality of inlets, and among the plurality of inlets, at least any one pair is installed such that one end of each of the inlets of the at least any one pair faces opposite directions.
5. The dipping bath according to claim 1 , wherein at least a part on the side surface of the body is inclined such that an inner space becomes narrow in a direction from top to bottom.
6. The dipping bath according to claim 1 , wherein the inlet is located at an upper part of the side surface of the body.
7. The dipping bath according to claim 1 , further comprising a guide roll.
