Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the mounting structure of a stock solution supply plate to a furnace cloth in a filter press.

Conventionally, filter presses generally have a pair of furnace cloths interposed between adjacent door plates, and a stock solution supply plate made of a pair of plates sandwiching the furnace cloths. Tighten the plate to fix the stock solution supply plate, and supply the stock solution.
1. The stock solution is allowed to flow from the stock solution hole in the furnace plate through the punched opening formed in each furnace cloth to the stock solution supply communication opening of the stock solution supply plate, and further to the stock solution supply passage communicating downward from the communication opening.1. It is designed to be supplied to the furnace chamber formed between the furnace cloths.

By the way, the stock solution supply plate is fixed to the furnace cloth by gluing, sewing, bolting, etc., so that it does not fall off even when the furnace cloth is run during cleaning of the furnace cloth.

However, the mounting work for fixing the stock solution supply plate to the furnace cloth is complicated, and the structure is also complicated, such as requiring bolts and bolt mounting holes. Furthermore, if the stock solution supply plate is fixed to the furnace cloth with bolts or the like as described above, it will be easier to make repairs. 1 (It had a drawback that it was not easy to play.

In addition, since the stock solution supply plate is located between the furnace cloth and the furnace plate,
In a type of filter press that cleans the furnace cloth by running the furnace cloth, when the E cloth runs, the stock solution supply plate comes into contact with the filtration surface of the furnace plate, causing damage to the filtration surface or causing the furnace cloth to hang. There was a malfunction that caused the equipment to malfunction.

The present invention has been made in view of the above-mentioned problems, and the present invention is a filter press that has a simple structure, can be easily attached to and removed from the furnace cloth, and can be reliably fixed in a predetermined position. The purpose is to provide a mounting structure for the supply plate.

The attachment structure of the stock solution supply plate to the furnace cloth in the filter press according to the present invention is such that the insertion leg of the stock solution supply plate is inserted into the insertion portion formed on the inner surface of the opening of each furnace cloth. It is characterized by

The present invention will be specifically described below based on illustrated embodiments.

The stock solution supply plate 1 is shown as a pair of planarly symmetrical plates 1a+1b.

The plate material 1a is vertically long and relatively thin with a semicircular upper part. A circular stock solution supply communication opening 2 punched out in the thickness direction is formed in the upper portion thereof so as to communicate with the stock solution hole in the furnace plate. A concave groove 3a for supplying stock solution is formed downward from the communication opening 2 on each of the opposing surfaces of the plate material 1a. Therefore, a pair of plate materials 1a.

By pressing the opposing surfaces of 1b, the stock solution flowing into the plates 1a and 1b from the communication opening 2 is transferred to the stock solution supply passage 3 formed by the pair of grooves 3a and 3b.
It passes through and enters the T-chamber 14 formed between the pair of cloths 7, 7.

In addition, on both sides of each of the plate materials 1a and 1b,
Grooves 5, 5 are cut upward from the lower surface of the plate, respectively, to form prismatic insertion legs 6, 6.

The opposing surfaces 6a of the leg portions 6 are recessed one step further than the other surfaces of the plates 1a and 1b.

On the other hand, a pair of furnace cloths 7 on which the stock solution supply plate 1 is interposed,
7, as shown in FIG. 4, are each formed with a punched open lower part a that communicates with the communication opening 2 of the stock solution supply plate 1, and a plate material is formed around the punched open lower part a on the inner surface of each of the cloths 7. A reinforcing cloth 9 having approximately the same shape as 1a and lb is provided.

The reinforcing cloth 9 on both sides of the punched-open lower lower a is formed with an insertion tube 8 having a U-shaped cross section and made of the same cloth as the furnace cloth 7. Therefore, each of the plates 1a and 1b is attached to the oven cloth 7 by inserting the legs 6.6 of each of the plates 1a and 1b into the cylindrical portions 8 and 8 of each of the oven cloths 7, respectively.

Opening and tightening of the undiluted solution out-of-plane supply type furnace plates 10, 10 (see FIG. 5) on which the pair of furnace cloths 7, 7 to which the undiluted solution supply plates 1 are attached are interposed are performed as follows.

In the furnace cloth traveling type filter press, as shown in FIG. 6, when the furnace plate 10 is moved from the open frame state to the tightened state,
The stock solution supply plate 1 is fitted into the recess 12 around the stock solution hole 11 made of a packing member of the furnace plate 10, and the area around the communication opening 2 of the stock solution supply plate 1 is in close contact with the packing member of the recess 12, and the stock solution is Prevent it from entering between the furnace cloth 7 and the furnace plate 10.

Then, the stock solution passes through the stock solution hole 11 of the r-plate 10, the punched open lower a of the furnace cloth 7, the communication port 2 of the stock solution supply plate 1, and the stock solution is supplied from the communication opening 2 through a pair of grooves 3a and 3b. It flows reliably and smoothly through the passageway 3 into the opening chamber 14 formed between the pair of furnace cloths 7 and 7.

Usually, the furnace plates 10, 10 are opened after the completion of offshore fishing in order to recover offshore debris. This floating debris collection is performed by winding up the furnace cloth 7 onto a lower take-up roller 16 by the furnace cloth traveling device 15 and at the same time, injecting cleaning water from the cleaning nozzle 17 to wash the furnace cloth 7. . At this time, the pair of plates la and lb that were in close contact are separated together with the opening of the furnace plate 10.10, so the concave groove 3a of each plate la and lb is separated.
.

The undiluted solution etc. staying in 3b can be removed by its own weight. Moreover, since the stock solution supply plate 1 is interposed between the furnace cloth 7 and the furnace cloth 7, no protrusions are projected from the side surface of the furnace cloth 7. Therefore, when the r cloth 7 runs, the stock solution supply plate 1
may come into contact with the filter surface 13 etc. of the furnace cloth 10 and cause damage to the filter surface 13, cause failure of the cloth hanging device 19, or hinder vertical movement of the cloth 7. This allows the furnace cloth 7 to run smoothly.

The above-mentioned stock solution supply plate 1 can be similarly attached to a stock solution supply type furnace plate having stock solution holes in the filtration surface.

Further, as shown in FIG. 7, the stock solution supply plate 1 can be attached not only to a cloth running type filter press but also to a cloth vibrating type filter press. Reference numeral 18 denotes a furnace cloth vibrating device, and after the door plate 10.10 is opened, the furnace cloth vibrating device 1i vibrates the finished cloth 7 in a downward direction on the road, thereby peeling off the debris attached to the finished cloth 7. Perform offshore recovery. Therefore, as the furnace cloth 7 vibrates, the stock solution supply plate 1 also vibrates, and each plate material 1a,
The undiluted solution and the like remaining in the grooves 3a and 3b of 1b can be removed by their own weight. Furthermore, since the stock solution supply plate 1 is interposed between the furnace cloth 7 and the cleaning cloth 7, even if the cleaning cloth 7 is vibrated, the filtration surface 13 of the door plate 10 is not damaged at all.

The present invention is not limited to this example, but can be implemented in various other ways. For example, as shown in FIG. 8, insertion legs 20.degree. 20 protruding diagonally downward are formed at the upper portions of both sides of the plate material 22a of the stock solution supply plate 22, and the r cloth 7
The leg portions 20.20 may be respectively inserted into inclined tube portions 21.21 for insertion which are formed diagonally downward.

When the stock solution supply plate 22 is attached to the finished cloth 7 as described above, it becomes difficult for the stock solution supply plate 22 to be pulled out upwardly, and it is possible to hold the stock solution supply plate 22 to prevent it from coming off.

Further, as shown in FIG. 9, the plate material 23 of the stock solution supply plate 23
a pair of horizontal cylinder parts 25 for insertion formed on the furnace cloth 7, with T-shaped insertion legs 24 extending upward from the center of the upper end surface;
Both side parts 24a, 24a of the leg part 24 may be inserted into the inside of the leg part 25.

When the stock solution supply plate 23 is attached to the finished cloth 7 as described above, it can be easily held to prevent it from coming off.

Further, the reinforcing cloth may be made of cloth or may be a film or sheet made of synthetic resin instead of cloth, and the cylindrical portion may also be made of rubber tape or sheet made of synthetic resin instead of cloth. .

Moreover, although the cylinder part is formed of one cylinder as in the above embodiment, the cylinder part may be formed by combining several cylinders.

In addition, it is preferable to provide a retaining means on the cylindrical portion or the stock solution supply plate as appropriate to prevent the legs of the stock solution supply plate from easily coming off from the cylindrical portion due to running or vibration of the furnace cloth.

As described in detail in the above embodiments, the structure for attaching the stock solution supply plate to the oven cloth in the filter press according to the present invention is such that the stock solution supply plate is inserted into the insertion portion formed on the inner surface of the opening of each cloth. Since the installation is performed by inserting the legs, there is no need for complicated installation work such as tightening bolts, and the installation and removal can be performed extremely easily, and it can be held securely in a predetermined position. In addition, the above-mentioned stock solution supply plate is installed between a pair of furnace cloths, and since no protrusions protrude from the side of the furnace cloth door plate, when the furnace cloth is moved during cleaning or when the cloth vibrates. There is no damage to the door panels, etc., or damage to the hanging cloth hanging device, etc.
