CN-117070928-B - Surface treatment device

Abstract

The invention provides a surface treatment device, which reduces the scattering amount of a treatment liquid (Q) of a casting type surface treatment device. A honeycomb member (60) is provided under the conveyance hook (16). The honeycomb member (60) is formed by connecting a plurality of tubular members having hexagonal holes. When the treatment liquid (Q) falls in the vertical direction (arrow (alpha)) the treatment liquid (Q) passes through the through-holes of the honeycomb member. Then, when the liquid collides with the liquid surface (H), a part of the treatment liquid (Q) is rebounded. A part of the processing liquid (Q) rebounded bounces in an oblique direction, and thus collides with the inner walls of the through holes of the honeycomb member (60). Thereby, the amount of the treatment liquid (Q) appearing again on the upper surface of the through hole is reduced. Thus, the honeycomb member (60) realizes the function of preventing scattering.

Description

Surface treatment device The application is based on the division of the patent application of the application with the name of surface treatment device, the application date of which is 2019, 12, 25 and the application number of 201911357841.7. Technical Field The present invention relates to a surface treatment apparatus for a liquid bath, and more particularly, to a surface treatment apparatus for preventing liquid from splashing into an adjacent treatment chamber. Background Fig. 10 of patent document 1 discloses a casting surface treatment apparatus in which a scatter prevention material is provided at a lower portion of a workpiece. Patent document 1 Japanese patent application laid-open No. 2014-88600 As the scattering prevention material of patent document 1, there is disclosed a sponge, a filter, a fibrous material (chemical fiber lock (trademark) manufactured by TOYO cushiony corporation) (paragraph 0085 of patent document 1), but such a sufficient scattering prevention effect cannot be achieved. This is because, among these materials, the liquid droplets that collide with the surface of the scattering prevention material are directly rebounded. In creating this bounce, the liquid may mix into the adjacent process chamber. In order to solve this problem, it is considered to increase the distance between the process chambers or to make the lower surface of the spacer provided between the process chambers sufficiently higher than the rebound surface of the droplet, but as a result, the entire apparatus becomes large. Disclosure of Invention The present invention has been made to solve the above-described problems, and an object thereof is to provide a flow-through type surface treatment apparatus which can be miniaturized without mixing liquid into an adjacent treatment chamber. 1) The surface treatment apparatus includes a1 st treatment chamber in which a treatment object is carried in while being held in a vertical direction, a1 st treatment liquid pouring mechanism provided in the 1 st treatment chamber to pour the 1 st treatment liquid from an upper portion of the carried-in treatment object to a surface region of the treatment object held in the vertical direction, a2 nd treatment chamber adjacent to the 1 st treatment chamber in which the treatment object is carried in while being held in the vertical direction, a2 nd treatment liquid pouring mechanism provided in the 2 nd treatment chamber to pour the 2 nd treatment liquid from an upper portion of the carried-in treatment object to a surface region of the treatment object held in the vertical direction, a partition wall provided between the 1 st treatment chamber and the 2 nd treatment chamber, having a carrying-in opening in which the treatment object can be carried in while being held in the vertical direction, and a mixing-in reduction mechanism provided in the 1 st treatment chamber or in a cylindrical shape in which the mixing-in treatment liquid is prevented from flowing back from the upper portion of the 2 nd treatment chamber toward the surface region of the treatment object held in the vertical direction, and a mixing-in reduction mechanism provided in the vicinity of the vertical direction from the lower portion of the treatment chamber. When the treatment liquid passing through the opening is rebounded by the landing surface, the treatment liquid collides with the inner wall of the elongated single tubular member and falls down toward the landing surface. Thus, a liquid-flow surface treatment apparatus which is small in size and in which liquid is not mixed into an adjacent treatment chamber can be provided. 2) In the surface treatment apparatus according to the present invention, the shape of the surface treatment apparatus formed by disposing the plurality of elongated individual cylindrical members is a substantially honeycomb shape. Therefore, the treatment liquid collides with the inner wall of the elongated single tubular member having a substantially honeycomb shape and falls down toward the landing surface. 3) In the surface treatment apparatus of the present invention, the approximate honeycomb shape is a honeycomb shape. Therefore, the treatment liquid collides with the inner wall of the elongated single tubular member having a honeycomb shape, and falls down toward the landing surface. 4) In the surface treatment apparatus of the present invention, the surface treatment apparatus further comprises a1 st treatment liquid recovery means for recovering a1 st treatment liquid falling from a lower portion of the object to be treated and supplying the 1 st treatment liquid to the 1 st treatment liquid pouring means, The surface treatment apparatus further includes a2 nd treatment liquid recovery means for recovering the 2 nd treatment liquid falling from the lower portion of the object to be treated and supplying the 2 nd treatment liquid to the 2 nd treatment liquid pouring means. Therefore, it is possible to reduce the mixin
