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 include a pair of furnace cloths interposed between adjacent furnace plates, and a stock solution supply plate made of a pair of plates sandwiching the furnace cloths. The stock solution supply plate is fixed by tightening the plate, and the stock solution is supplied from the stock solution hole in the furnace plate through the punched opening formed in each furnace cloth.
The undiluted solution is allowed to flow through the undiluted solution supply communication opening of the undiluted solution supply plate, and further to the undiluted solution supply passage that communicates downward from the communication opening, and is supplied to the F 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 etc. as described above, when performing repair work or replacing the furnace cloth,
The drawback was that it was only easy to remove.

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 furnace cloth is running, the stock solution supply plate comes into contact with the P-filter surface of the furnace plate, causing damage to the P-filter surface. There were problems such as causing the fabric machine to malfunction.

The present invention has been made in view of the above problems, and has a simple structure and can be easily attached and detached from the furnace cloth.
Moreover, it is an object of the present invention to provide a structure for attaching a stock solution supply plate to a furnace cloth in a filter press that can be securely fixed in a predetermined position.

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 circumferential surface of the opening of each furnace cloth. It is characterized by what it did.

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

The stock solution supply plate is composed of a pair of planarly symmetrical plates 1a and 1b, one of which is shown in FIGS. 1-4.

The plate material 1a is vertically long and relatively thin with a semicircular upper part.

A circular stock solution supply opening 2 punched out in the thickness direction is formed in the upper part thereof, so that it can communicate with the stock solution hole in the door plate.

A concave groove 3a for supplying the stock solution is formed downward from the husband and wife communication opening 2 on opposing surfaces of the plate 1a.

Therefore, by pressing the opposing surfaces of the pair of plate materials Ia and 1b, the plate materials 1a and 1b can be opened from the communication opening 2.
The undiluted solution that has flowed into the undiluted solution passes through the undiluted solution supply passage 3 formed by the pair of grooves 3a and 3b, and passes through the pair of furnace cloths 7,
Enter the furnace chamber 14 formed between 7 and 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,
As shown in FIG. 4, each of the furnace cloths 7 is 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 furnace cloth 7. A reinforcing cloth 9 having approximately the same shape as 1a and Ib 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, 1b is attached to the oven cloth 7 by inserting the leg portions 6.degree. 6 of each of the plates 1a, Ib into the cylindrical portions 8, 8 of each oven cloth 7, respectively.

Opening and tightening of the undiluted solution filtration in-plane supply type door plates 10, 10 (see FIG. 5), which interpose the pair of furnace cloths 7, 7 to which the undiluted solution supply plate 1 is attached, are performed as follows.

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

The undiluted solution passes through the undiluted solution hole 11 of the door plate 10, through the punched open lower a1 of the furnace cloth 7, and the communication opening 2 of the undiluted solution supply plate 1, and from the communication opening 2, the undiluted solution supply passage formed by a pair of grooves 3a and 3b. 3, it reliably and smoothly flows into the furnace chamber 14 formed between the pair of furnace cloths 7.7.

Usually, the door panels io and io are opened to collect p-liquid after filtration.

This filtrate recovery is performed by winding up the furnace cloth 7 onto the lower winding 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 panels 1a and lb that were in close contact with each other were removed from the door panel 1.
Since they are separated together with the open frames 0 and 10, the grooves 3a of each plate material 1a and Ib.

The undiluted solution etc. staying in 3b can be removed by its own weight.

In addition, since the stock solution supply plate 1 is interposed between the furnace cloth 7 and the furnace cloth 7, no protrusions protrude from the side surface of the P plate of the furnace cloth 7.

Therefore, when the furnace cloth 7 is traveling, the stock solution supply plate 1 is connected to the furnace cloth 10.
It does not come into contact with the filtration surface 13 or the like, causing damage to the filtration surface 13, causing failure of the furnace cloth hanging device 19, or preventing the vertical movement of the furnace cloth 7. The furnace cloth 7 can be run smoothly.

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

Furthermore, as shown in FIG. 7, the stock solution supply plate 1 can be attached not only to the cloth traveling type filter press but also to the cloth vibrating type filter press.

18 is a furnace cloth vibrating device, and after opening the furnace plates 10, 10,
The furnace cloth vibrating device 18 vibrates the furnace cloth 7 in a downward direction on the road to separate the filtrate adhering to the furnace cloth 7 and recover the p liquid.

Therefore, the undiluted solution supply plate 1 also vibrates with the vibration of the furnace cloth 7, and the undiluted solution etc. that have remained in the grooves 3a and 3b of each of the plate members 1a and 1'b can be removed by their own weight.

Further, since the stock solution supply plate 1 is interposed between the furnace cloth 7 and the furnace cloth 1, even if the furnace 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.
Legs 20.20 for insertion that protrude diagonally downward are formed on the upper sides of both sides of 2a. may be inserted into the stock solution supply plate 22 as described above.
When attached to the furnace cloth 7, the stock solution supply plate 22 becomes difficult to pull out upward, and can be held to prevent it from coming out.

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 difference side leg parts 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 furnace cloth 7 as described above, it can be easily held to prevent it from slipping out.

Further, although the reinforcing cloth is made of cloth, it may be made of 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. good.

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 furnace 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 peripheral surface of the opening of each furnace cloth. Since it is installed by inserting the legs, there is no need for complicated installation work such as tightening bolts, and it is extremely easy to install and remove, and it can be held securely in a predetermined position.

Furthermore, since the stock solution supply plate is installed between the pair of furnace cloths and no protrusions protrude from the side of the door plate of the furnace cloth,
When the furnace cloth is moved or vibrates when cleaning the furnace cloth, it will not damage the sliding surface of the door plate or cause the furnace cloth measuring device to malfunction.
