2. Description of the Related Art As a prior art of this kind, Japanese Utility Model Publication No.
As shown in JP-A-31291, a tip nozzle of a link mechanism which expands and contracts in a pantograph manner is introduced between cloths obtained by opening a filter board of a filter press and spraying washing water to remove the cloth. Devices for cleaning are known.

[0003]

In this prior art, a predetermined cleaning effect can be achieved as a device for cleaning cloth. However, since the link mechanism of the cleaning device that expands and contracts is a pantograph type, It is necessary to widen the interval between the plates, and when folded, the link mechanism extends laterally, making the structure complicated and expensive. The present invention has been made in view of the above-mentioned problems of the prior art and has solved the problem. The present invention can reliably wash the cloth between narrow plates and can form a compact filter press as a whole. The purpose of the present invention is to obtain a simple and inexpensive cleaning device.

[0004]

According to the present invention, as a means for achieving the above object, a movable gantry capable of moving in a direction in which the 板 plate is opened is installed at a lower portion of the 第 plate. One cylinder is erected and the piston rod portions of both first cylinders are connected to each other by a connecting member.
A second cylinder is erected on the connecting member, and an injection pipe is attached to a piston rod of the second cylinder.
An injection tube is introduced between the filter plates, and the surface of the filter plate and / or the cloth is washed with the washing water discharged from the injection tube.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; Reference numeral 1 denotes a movable base, and a plate 1
7 is extended over the two guide rails 2 provided side by side at a distance along the direction in which the guide rollers 3 are separated.
3, the plate can be freely moved in the direction in which the plate is opened. Reference numeral 4 denotes a first cylinder,
At the same time, two bolts are provided and fixed by the U bolts 12 respectively, and the tip of the piston rod 5 of the first cylinder 4 is connected and fixed by the connecting member 6. Reference numeral 7 denotes a second cylinder, which is fixed to a central portion of the connecting member 6,
An injection pipe 9 is provided at the tip of the piston rod 8 of the second cylinder 7.
Is fixed so as to protrude left and right in the width direction of the plate 17. A large number of spray nozzles 10 are provided in the injection pipe 9 in the longitudinal direction at intervals on the front and back sides of the injection pipe 9. Further, a washing hose 11 is connected to the injection pipe 9, and washing water is supplied from a supply source (not shown). Proximity switches 13 and 14 are provided at the lower and upper limits of the first cylinder 4, respectively, and proximity switches 15 and 16 are provided at the lower and upper limits of the second cylinder 7, respectively. Reference numeral 18 denotes a cloth.

[0006] In order to wash the cloth by using the above-mentioned structure, the first room is set in a predetermined separated state, and the first cloth is placed at a lower position between the cloths. The movable gantry 1 is moved and stopped by driving means (not shown) such as a chain. At that time, the proximity switches 13 and 15
To check whether the first cylinder 4 and the second cylinder 7 are at the lower limit, respectively, and move. When the movable gantry 1 stops at a predetermined position, the first cylinder 4 and the second cylinder 7
Is supplied to the cylinder chamber on the side opposite to the piston rod 5 and the piston rod 8 side. As a result, the respective piston rods 5 of the two first cylinders 4 are fixed by the connecting member 6, so that they rise in synchronization with each other, and the injection pipe 9 starts to rise. At the same time, the cleaning hose 11
, The washing water is supplied from above, and the cloth 18 is washed from below by the spray nozzles 10 attached to the front side and the back side of the injection pipe 9. Further, when the piston rod 5 of the first cylinder 4 reaches the upper limit, the piston rod 8 of the second cylinder 7 starts to rise, so that the injection pipe 9 continues to rise, and the cloth 18 is reliably washed to the upper end. When the piston rod 5 of the first cylinder 4 and the piston rod 8 of the second cylinder 7 reach the upper limits, respectively,
The upper limit is detected by the proximity switches 14 and 16. After a certain period of time, the compressed air or oil supplied to the first cylinder 4 and the second cylinder 7 is switched, and the piston rod 5 of the first cylinder 4 and the second cylinder 7
And the piston rod 5 and the piston rod 8 move in the downward direction, respectively, and when both reach the lower limit, the supply of the washing water from the washing hose 11 is stopped, and the first cloth Washing is completed. One ▲ ▼ board to wash the ▲ ▼ cloth in the next ▲ ▼ room continuously ▲ ▼
The platen is moved by the plate moving device, and at the same time, the movable base 1 is moved by one drive unit by the driving means, automatically detected and stopped, and the above operation is repeated. In this way, the cloth 18 is moved one after another to completely wash the cloth 18.

In the above embodiment, the cloth 18
However, the present invention is not limited thereto, and the plate 17 may be washed, or both the plate 17 and the cloth 18 may be washed.

[0008]

[Effect of the Invention] As described above, the embodiment is described in detail.
In the present invention, the stroke of the injection pipe moving up and down is combined in two stages with three cylinders, so that the stroke can be reduced to about half as compared with a structure in which the entire stroke is operated with only one cylinder. In addition, the height dimension of the entire filter press can be reduced. Also, since the size of the plate in the opening direction does not become large as in the pantograph type, the space between the plates is narrow and the cleaning effect of the cloth is improved. The present invention has an excellent effect of providing a simple cleaning device.
