Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a cloth washing device in a filter press of a type in which cloths provided between respective plates are simultaneously moved up and down.

[Conventional technology]

Examples of this type of cloth cleaning device include, for example, Japanese Patent Publication No. 52-6.
As shown in Fig. 8 and Fig. 9 of No. 903, S. 57-27
There is one such as that shown in FIGS. 1 to 3 of No. 532. The Japanese Examined Patent Publication No. 52-6903 has a cloth washing pipe attached to the bottom of each plate, and the Japanese Examined Japanese Patent Publication No. 57-27532 has a washing pipe corresponding to the cloth provided between the plates. This is made to stand by and is moved to a predetermined position at the time of washing.

[Problems to be solved by the invention]

However, in the one attached to the plate as shown in FIGS. 8 and 9 (reference numerals 35 to 37) of Japanese Patent Publication No. 52-6903,
When the plate is moved (opened and closed), the water supply pipe is dragged, which not only hinders the opening and closing of the plate, but also because it is high-pressure water, and piping is also troublesome. Also, the actual public Sho 57-275
The structure of No. 32 is also complicated, and the high-pressure hose for washing water is dragged in the same way as Japanese Patent Publication No. 52-6903.

[Means for solving problems]

Therefore, the present invention solves the above-mentioned conventional problems, and the gist of the present invention is to arrange a large number of plates movably on a guide rail provided horizontally and In discharging the slag generated between the plates, the plates are opened at the same time, and the cloth provided between the plates is moved up and down.
A plate receiving plate movable in a direction orthogonal to the plate row is arranged below the plate, and a cleaning pipe having an injection nozzle is provided in this liquid receiving plate, and when the liquid receiving plate is moved to close the lower part of the plate, The injection nozzle faces the cloth.

[Action]

The device according to the present invention is configured as described above, and in order to wash the cloth using the device, the plate is opened, the cloth is moved downward, the slag is discharged, and then the liquid receiving plate is closed. ,
After moving the cloth upward, the washing water may be sprayed from the washing nozzle provided on the liquid receiving plate. By doing so, the cloth that moves upward can be uniformly washed. At this time, since the liquid receiving plate is closed, the cleaning drainage can be discharged by the liquid receiving plate without wetting the slag. . And since the cleaning nozzle is attached to the liquid receiving plate, there is no need to drag the water supply pipe unlike the conventional one described above.
It can be operated smoothly. Hereinafter, the invention will be specifically described with reference to the drawings.

〔Example〕

In FIG. 1, reference numeral 1 is a frame, 2 is a guide rail bridged to the frame 1, 3 is a plate movably juxtaposed with the guide rail 2, 4 is a link chain connecting these plates 3 loosely, and 5 is the above plate. The figure shows a state in which the plate 3 is opened by a hydraulic cylinder for opening and closing and tightening the plate 3.

Next, reference numeral 6 is a cloth provided between the plates, and as shown in FIG. 2, the upper ends of a pair of cloths 6 provided so as to cover the overbed 3a of the left and right plates 3 are joined by an upper support bar 7. The lower ends of the pair of cloths are wound around a return roll 8 provided at the lower part of the plate 3 and then joined with the lower end of the cloth 6 between the adjacent plates. The support bar 9 and the above-mentioned upper support bar 7 are connected by a chain 12 wound around a sprocket 11 of a drive roll provided on the upper part of the plate 3, and when the lower support bar 9 is pulled up, a pair of cloths 6 are pulled down. The return roll 8 makes a U-turn. Reference numeral 13 is a cleaning pipe provided so as to face the portion where the cloth 6 makes a U-turn, and 13a is an injection nozzle.

Next, the cleaning pipe 13 will be described in detail with reference to FIG. 3. The cleaning pipe 13 is fixed to a pair of liquid receiving plates 14 that can be opened and closed below the plate row. 15 is a supply pipe for washing water. The left and right liquid receiving plates 14 are provided with wheels 16 as shown in the figure so that they can be moved left and right on rails 17 to close and open the lower part of the plate row. Reference numeral 18 is a trough for discharging the washing water, reference numeral 19 is a guide plate for discharging the cake performed with the liquid receiving plate 14 opened, and reference numeral 20 is a discharging roll used for transferring the cake. The liquid receiving plate 14 is used to receive the liquid when it is discharged without using it separately.
In order to wash the cloth 6 with the apparatus configured as described above, after discharging the cake, the lower side of the plate row is closed by the left and right liquid receiving plates 14, and then the cloth 6 is moved upward while the washing pipe 13 is moved. The washing water may be jetted from the jet nozzle 13a to the cloth 6 moving upward by making a U-turn. At this time, since the cloth 6 makes a U-turn, its eyes are open, and even the cake clogged with eyes can be completely removed.

[Effect of device]

In this way, in this invention, since the cleaning pipe is attached to the liquid receiving plate, when cleaning the cloth, it only needs to move slightly below the plate row, and it can be moved by dragging the hose or moving to the plate one by one. It is also convenient to operate compared to the one with a cleaning pipe attached.

[Brief description of drawings]

FIG. 1 is a schematic side view of a filter press according to the present invention, FIG. 2 is a longitudinal side view showing a part of the cloth press for explaining a traveling mechanism of the cloth, and FIG. It is a front view of a part. 2 guide rails, 3 liquids, 6 cloths, 13 cleaning pipes, 13a injection nozzles, 14 liquid receiving plates

Claims (1)

[Scope of utility model registration request] 1. A large number of plates 3 are movably arranged on a horizontally arranged guide rail 2, and the plates are opened all at once in order to discharge the slag generated between the plates, and these plates are simultaneously opened.
