[0018] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.
[0019] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.
[0020] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0022] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0023] Please refer to the attached Figure 2-4 An overflow device for removing floating foreign matter includes a pool body and an overflow trough connected to the pool body. An overflow pipe is connected to the overflow trough at the bottom of the pool body. The other end of the overflow pipe is connected to the pool body. A filter 4 and a pump body 5 are connected to the overflow pipe in sequence. The overflow trough is an H-shaped overflow trough 3 in a top view.
[0024] An overflow port 2 is provided on the inner wall of the H-shaped overflow tank 3, and the height of the overflow port 2 is lower than the liquid level in the tank body.
[0025] like Figure 4 As shown, in one embodiment, the middle cross beam of the H-shaped overflow trough 3 is provided with multiple groups for use in producing multiple groups of roll-to-roll production products.
[0026] The H-type overflow device provided by the utility model has a height of the H inner side of the tank body lower than the liquid level of the solution treatment tank, and the height of the H-type tank body at other positions is higher than the liquid level of the solution treatment tank. Therefore, floating foreign matter on the surface of the treatment tank overflows into the H-type overflow tank with the solution. The bottom of the H-type overflow tank is connected to an overflow pipe, a filter device and a pump. The floating foreign matter in the solution is transported to the filter device through the overflow pipe. The filter device will filter out various foreign matter such as floating and granular foreign matter, and the purified solution is transported back to the solution treatment tank through the pump. By continuously circulating this operation, the cleanliness of the solution in the treatment tank can be guaranteed. Floating foreign matter in the solution treatment tank is truly eliminated, solving the adverse effects on the product caused by the adhesion and carrying out of floating foreign matter.
[0027] Furthermore, all floating foreign matter on the surface of the solution in the solution treatment tank is discharged from the inside of the H-shaped overflow tank. When the product is produced in roll-to-roll mode, the floating foreign matter on the surface of the product is dispersed and discharged to both sides when the product passes through the inside of the H-shaped overflow tank via roller conveyor, further ensuring that the product surface will not be attached with floating foreign matter, solving the problem of product short circuit and contamination of other tank solutions caused by the adhesion and carry-out of floating foreign matter, thereby improving product yield.
[0028] The utility model is not limited to processing 2 columns of roll-to-roll production at the same time, and can process multiple columns of roll-to-roll product production at the same time by increasing the number of H rows of overflow slots.
