Detailed Description of the Invention Technical Field The present invention relates to a cloth traveling type filter press in which a pair of furnace cloths are run vertically between adjacent furnace plates, and more specifically, to This invention relates to the structure of a stock solution supply device that guides stock solution between a pair of furnace cloths from a stock solution hole in a door plate in a state where the door plate is tightened.

BACKGROUND ART Conventionally, a filter press has a pair of furnace cloths interposed between adjacent door plates, and a stock solution supply plate interposed between the pair of furnace cloths. This stock solution supply plate is provided with a through hole communicating with the stock solution supply port of the furnace cloth, and is provided with a liquid supply path extending downward from the through hole and having an open lower end. Then, tighten the adjacent furnace plates to fix the stock solution supply plate, and pass the stock solution through the stock solution hole in the furnace plate, the stock solution supply port on the furnace cloth, and the solution supply path from the through hole of the stock solution supply plate to the space between the furnace cloths. It is supplied to the furnace chamber formed in the following manner.

By the way, when the stock solution supply plate is removed, since a liquid supply path is provided inside the stock solution supply plate, even if the stock solution remains in the liquid supply path, it can be completely cleaned. There was a problem that the liquid path was blocked. In addition, since the stock solution supply plate is composed of a single plate, there is a problem in that it is difficult to repair a blocked solution supply path.

OBJECTS OF THE INVENTION The object of the present invention is to solve the above-mentioned problems, and to provide a method for easily cleaning the remaining undiluted solution and for smoothly supplying the undiluted solution into the furnace chamber formed between a pair of furnace cloths. It is an object of the present invention to provide a stock solution supply device for a filter press that can be easily repaired.

The uninvented structure and operation is such that a pair of furnace cloths sandwiched between adjacent furnace plates have surfaces facing each other around each stock solution supply port.
Washer members having through holes are brought into contact with each other, and the washer members are attached to the furnace cloth with an attachment member, and the washer members are provided on opposing surfaces of at least one of the opposing washer members when tightening the furnace plate. A gap is provided between the opposing washer members by abutting the protruding portion against the opposing surface of the other washer member, and the undiluted solution is passed through the undiluted solution hole of the furnace plate, the undiluted solution supply port of the furnace cloth, and the washer member. It is characterized in that it is supplied between the pair of furnace cloths through the opening and further through the gap between the washer members.

Effects of the Invention According to the present invention, with the above structure, the opposing washer members can be separated when the furnace plate is opened, and the undiluted solution remaining between both the washer members can be easily cleaned. It is possible to reliably prevent the gap between the two seat members from clogging, and the raw solution can be smoothly supplied into the furnace chamber formed between the pair of furnace cloths, and it is easy to repair. It can also be made simple and easy to assemble. In addition, since the protruding part of at least one washer member is butted against the opposing surface of the other washer part, the protruding parts can be matched stably and reliably, and a gap can be reliably provided between both washer members. be able to. Further, according to the present invention, since the washer member is attached around the raw solution supply port of the furnace cloth, the raw solution hole of the furnace plate and the through hole of the washer member are reliably communicated, and the washer member is securely attached to the furnace plate. [Can be done. In addition, in the conventional stock solution supply plate, the thickness of the plate is thick because the liquid supply path is provided inside the plate, and therefore the plate itself is heavy and puts an excessive load on the furnace cloth.However, according to the present invention, the double washer member Since the protrusion provided on at least one of the washer parts abuts against the opposing surface of the other washer member to form a gap, the washer member attached to the furnace cloth can be made thinner and thinner than the above-mentioned conventional stock solution supply plate. The weight can be reduced, and overload can be prevented from being applied to the furnace cloth. Further, according to the present invention, there is no restriction on the liquid supply path for supplying the stock solution into the furnace chamber, and the stock solution can be supplied from the through hole of the washer member in any direction such as up, down, left, or right around the washer member, so that r1 Production efficiency can be improved by increasing the rate of supplying the raw solution into the room. In addition, the conventional stock solution supply plate had a liquid supply path inside it, so it was necessary to improve the accuracy of the entire plate.
According to the present invention, since the protrusion of one washer member is brought into contact with the opposing surface of the other washer member to form a gap,
It is only necessary to increase the accuracy of the protrusion and the abutting portion of the protrusion, and manufacturing costs can be reduced.

Further, according to the present invention, since a washer member is attached to each furnace cloth, the movement of each furnace cloth can be made smooth without being obstructed.
