Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a furnace cloth device for a so-called furnace cloth fixed type filter press in which the upper end of the furnace cloth is suspended above the furnace plate and a part of the furnace cloth is fixed to the furnace plate side. .

Conventionally, various furnace cloth fixing structures have been known in this type of furnace futon type filter press.

For example, in Japanese Utility Model Publication No. 38-21094, furnace cloths hung on both sides of a furnace plate are connected in the raw solution hole of the furnace plate to form a raw solution supply hole of the furnace cloth, and A structure is disclosed in which a furnace cloth is fixed at the raw solution hole.

Furthermore, Japanese Patent Publication No. 39-20697 discloses a structure in which a mounting bracket having a solution hole is used to tighten and fix the solution hole of the furnace cloth to the solution hole of the furnace plate.
-20384 publication and 45-13027 publication,
A structure is disclosed in which the mounting fittings of the furnace cloth are brought into contact with each other when the furnace plate is tightened, and a groove for distributing the stock solution is provided between the fittings.

As mentioned above, in the conventional furnace cloth fixing structure, the furnace cloth is fixed to the raw solution hole of the furnace plate, so the upper end of the furnace cloth is supported elastically using the furnace cloth hanging rod. Even if the furnace cloth is vibrated by applying vibration to the furnace cloth hanging rod when the filter press is opened (separate frame), the vibration of the furnace cloth is not transmitted to the portion below the stock solution hole.

For this reason, with a highly sticky furnace cake, the upper half can be separated from the furnace cloth and collected by falling due to the vibration of the furnace cloth, but some of the lower half can be recovered because there is no vibration of the furnace cloth. Even if the cloth falls under its own weight, the furnace cloth remains attached to the surface of the furnace cloth and cannot be peeled off, resulting in a problem of deterioration of lacquer performance. The present invention has been made in view of this problem, and includes a support structure for a furnace cloth that can provide chicks with good furnace clearness over the entire surface of the furnace cloth when the furnace plate is opened. The basic objective is to provide a furnace cloth device for a fixed sea cloth filter press.

Furthermore, the present invention provides for supplying the undiluted solution between the furnace cloth and the furnace plate so that the furnace cloth can be easily attached to the furnace plate and the vibration of the furnace cloth is not restricted in any way by anything other than the furnace cloth. Another objective is to improve the stock solution supply structure.

For this reason, in the present invention, a furnace cloth hanger is supported vibrably above the furnace plate via a spring member, and the upper end of the furnace cloth is supported by the furnace cloth hanger rod, while a furnace cloth hanger is supported at the bottom of the furnace plate. The lower end of the furnace cloth is attached using the cloth lower end attachment member, and the raw solution supply plate is attached to the furnace cloth so as to match the raw solution supply hole of the furnace plate.With the furnace plates mutually tightened, a pair of opposing furnaces At least one of the cloth stock solution supply plates was provided with a protrusion that formed a gap between both stock solution supply plates, and the stock solution was supplied between the pair of furnace cloths through the gap.

The furnace cloth lower end attachment member includes a furnace cloth locking rod that locks the lower end of the furnace cloth, and a support fitting that supports the end of the furnace cloth locking rod while allowing vibration in the vertical direction. The supporting metal fittings are fixed to the lower end of the furnace plate, and the protruding portion of the stock solution supply plate is made of the head of a bolt that attaches the stock solution supply plate to the furnace cloth or a nut that is fixed to the bolt. The purpose of the present invention is to provide a furnace cloth bag pupil of a furnace cloth fixed type filter press in which the furnace cloth can vibrate together with the stock solution supply plate in a state in which the furnace cloths are opened to each other. The above-mentioned gap is formed by butting bolt heads against each other, or nuts against each other, or by butting together bolt heads and a stock solution supply plate. The above bolts include countersunk head bolts, blood screws, hexagonal head bolts,
means pin etc. As described above, in the furnace cloth device according to the present invention, by applying vibration to the upper end support member of the furnace cloth in a state where the furnace plates are opened from each other, it is possible to completely vibrate the furnace cloth with the lower end fixed. The stock solution supply plate vibrates together with the furnace cloth and does not restrict the vibration of the furnace cloth.

Therefore, the cake next to the furnace is completely separated from the furnace cloth by the full-scale vibration of the furnace cloth, and the furnace bamboo cake can be recovered satisfactorily. In addition, in the present invention, the term "roban" means:
In addition to ordinary furnace plates, the present invention can also be applied to filter presses that include so-called pressing furnace plates, in which ordinary furnace cloths and pressing furnace plates are arranged alternately, and filter presses that are composed only of pressing furnace plates.

Furthermore, the term "fixed furnace cloth type" is used in contrast to the term "furnace cloth traveling type", and the effective working surface of the furnace cloth is not moved vertically relative to the furnace plate, and vibrations are prevented. However, it means a type that is substantially fixed to the furnace plate.

The peeling of the cake can be promoted, and this type of filter press has the advantage of stably maintaining its filtration performance.

In addition, since the furnace cloth locking rod is supported on the supporting metal fitting at the lower end of the furnace plate in a manner that allows vibration in the vertical direction, no overload is applied to the furnace cloth even when the furnace cloth is vibrated together with the raw solution supply plate. Moreover, there is no way to restrict the vibration of the furnace cloth. Also, when the furnace cloth vibrates,
Since the stock solution supply plate also vibrates together with the furnace cloth, the stock solution supply plate can promote the vibration of the furnace cloth by its own weight.
Also, since the furnace cloth is equipped with a stock solution supply plate, there are no vertical wrinkles on the furnace cloth surface. It is possible to uniformly vibrate the entire surface of the furnace cloth, which is held flat, without causing diagonal wrinkles. In addition, since the furnace cloth is not fixed to the furnace plate, it is easy to attach and remove the furnace cloth, and the vertical attachment of the furnace cloth by the raw solution supply plate and the furnace plate is released for each furnace plate connection frame. Tightening of the furnace cloth, fatigue,
Damage etc. can be effectively prevented. Furthermore, since the bolt head of the protruding part of the stock solution supply plate is constructed with a nut, a gap is formed between the pair of stock solution supply plates in all directions such as top, bottom, left and right, and the stock solution is distributed between the pair of furnace cloths as a whole. Can be supplied.
