The undiluted solution supply plate may be fixed, or the undiluted solution supply plywood may be suspended from the furnace cloth using a hanging cord or the like.

Alternatively, the longitudinal direction of the stock solution supply plate may not be the vertical direction, but may be attached to the furnace cloth along a horizontal direction or an oblique direction corresponding to the position of the stock solution hole on the furnace slope. In addition, each stock solution supply device can be applied to a filter press consisting only of a pressing furnace plate or a normal furnace plate, and it can also be applied to a furnace plate of the in-plane stock solution supply type that supplies the stock solution to the furnace filtration surface. good. Also,
The shape of each stock solution supply plate is not limited to that shown in the drawings, but may be any shape as long as it can achieve the same effects.
Further, the manner in which the furnace plate is hung is not limited to the above-mentioned embodiments, and the filter press may be hung over the furnace plate, or may be hung from a so-called pantograph-type hanging device provided on the furnace plate. In addition, with these types of hanging devices, the cleaning device for the suspended furnace cloth can be inserted between the furnace plates from the outside of the furnace plates, or left in standby at the bottom of the furnace plates, When opening the frame, a cleaning pipe may be brought close to the furnace cloth surface to perform the cleaning operation. Effects of the Invention The present invention attaches a stock solution supply plate to each furnace cloth, and when the furnace plates are tightened, the two stock solution supply plates are butted against each other, and the food is removed from the through hole of one stock solution supply plate from the other stock solution supply plate. While the raw solution is supplied into the furnace chamber from the part with the entrance so that it protrudes, both the raw solution supply plates are separated when the furnace plate is opened, so that the furnace bamboo can be shaken off by the vibration of the furnace cloth. The undiluted solution remaining on each undiluted solution supply plate can be easily cleaned, the undiluted solution can be smoothly supplied to the furnace chamber between the pair of furnace cloths, and repairs can be easily performed. .

Moreover, since the stock solution supply plates are each made flat, when the furnace plate is tightened, the abutment area of both stock solution supply plates becomes large, and the butt is ensured and stabilized. Further, each stock solution supply plate is configured to be flat and form one through hole, so the structure is simple and therefore manufacturing can be performed easily. Furthermore, even if the two stock solution supply plates are butted against each other, for example, even if they are slightly deviated in the protruding direction of the through holes, the influence on the suitability of both the through holes and the suitability for filling the furnace chamber can be reduced. Furthermore, since a stock solution supply plate is attached to each furnace cloth, the movement of each furnace cloth can be carried out smoothly without being hindered.
