Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves tightening adjacent front and rear plates with a pair of cloth in between, forming a chamber surrounded by cloth between the plates, supplying the stock solution to be passed into the chamber,
This invention relates to a single filter press that separates a stock solution into a residue and a liquid.

Conventionally, various types of single filter presses of this type, especially concentrate supply devices for supplying the concentrate indoors, have been known, but the conventional concentrate supply devices are plate-shaped or funnel-shaped small objects that form the concentrate supply passage. It is formed as a part and is attached to a plate or to a cloth such that the small part can be positioned between a pair of cloths with the plates fastened together.

However, in particular, in the fabric traveling type single filter press, since the fabric is made to run, various difficulties arise in supporting and positioning the stock solution supply tool attached to the fabric side.

That is, when supporting the stock solution supply tool on cloth,
The support strength of the cloth is essentially insufficient, and the cloth tends to stretch, wear out, and even tear. In such a case, there is a problem that the positioning of the stock solution supply tool becomes unstable.

The present invention has been made in view of such conventional problems, and the stock solution supply tool is made essentially independent of the plate and the cloth, and is interposed between the cloths as an independent entity, and when the cloths are tightened together. The object of the present invention is to provide a single filter press that can stably supply a stock solution to a chamber between a pair of cloths.

In the present invention, a stock solution supply tool 3 having the same outer peripheral shape as the plates 1 and 2 is interposed between the front and rear plates 1 and 2 which are adjacent to each other, and a chamber 4 is formed between the front and rear plates 1 and 2 which are adjacent to each other. This is a single filter press for supplying a stock solution to
A main body 5 consisting of a frame corresponding to the outer peripheral shape of the main body 5 and having fastening surfaces 5a, 5a on both sides thereof
It is constructed by integrally forming an annular convex part 7 on one side of an annular part 6 formed above the center part of the upper side,
One plate 2 is formed so that its periphery is thinner than the filter surface 2a by an amount approximately equal to the thickness of the main body 5 of the stock solution supply tool 3, and the stock solution supply tool 3 is placed from the front and back of the plate 2 with the cloth 8 in between. Fitting parts 9, 9 that can be fitted are formed, and the filter surface 2a of the plate 2 is formed.
and the tightening surface 5a of the main body 5 of the stock solution supply tool 3 are configured so that they are substantially flush with each other, and the other plate 1 forming a chamber between the plate 2 and the tightening surface 5a of the main body 5 of the stock solution supply tool 3 is configured to The filter surface 1a is a concave surface that is one step lower than the outer frame, leaving the outer frame portion in contact with the surface 5a, and the convex portion 7 of the stock solution supply tool 3 is provided in the semicircular portion 1b at the center of the upper side of the plate 1. A recessed portion 10 to be fitted is formed continuously on the filter surface 1a so as to be substantially flush with the filter surface 1a, and the semicircular portion 1b has the stock solution hole 11 penetrated therethrough. In the opening,

Then, when plates 1 and 2 are tightened in the front and back direction,
The stock solution supply tool 3 is also held fluid-tightly by the clamping surfaces of the front and rear plates 1 and 2 with the cloth 8 in between, and when the stock solution is forced into the stock solution passageway 15 that communicates with the series,
The stock solution is smoothly supplied to the chamber 4 formed between the plates 1 and 2 through the downward stock solution supply hole 14 formed in the convex portion 7 of the stock solution supply tool 3.

The stock solution supplied into the chamber 4 is separated into residue and liquid by a pair of cloths 8, 8 that cover the chamber 4, and the liquid that has passed through the cloth 8 is separated from the residue and liquid by a pair of cloths 8, 8 that cover the chamber 4. The liquid is collected in the liquid recovery passage through the liquid drain hole.

The above-mentioned stock solution supply tool can therefore be supported in a freely openable and closable manner on the supporting body of the filter press in the same way as the plate, and can be mutually opened and closed with the plate. A single filter press is constructed between the
