Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fully automatic multi-stage switching mobile dehydrator for cloth used in the final step of various chemical treatment processes.

As this type of dewatering machine, one having a configuration called a filter press that utilizes squeezing force is known.

For example, a first cloth is provided with a diaphragm on both sides and a first cloth covering the surface of the diaphragm.
plate, and a second cloth on the side opposite to the first cloth.
A second plate provided with cloth is arranged alternately to form a chamber by the first and second cloths, and after supplying sludge (untreated stock solution) into the chamber, The sludge is dehydrated to form a cake across the chamber by blowing compressed air into the plates to inflate a diaphragm and bring the first fabric closer to the second fabric.
The same dewatering process is then repeated by opening the first and second plates, discharging the cake, forming a new overchamber, and supplying sludge.

By the way, in such a conventional dehydrator, the first and second cloths that form the overchamber are both run on the sides of the first and second plates, which makes the cloth feeding mechanism complicated, and it is not possible to fully automate it. In this case, it is inevitable that the device structure becomes complicated.

Furthermore, the task of replacing the cloth becomes complicated, which causes a decrease in the operating efficiency of the apparatus.

The present invention was made in response to the above-mentioned problems. One of the pair of cloths forming the overchamber is fixed to one plate, and only the other cloth runs along the side of the other plate. The object of the present invention is to provide a multi-stage switching movable fully automatic dehydrator for cloth which is configured to eliminate the drawbacks of the conventional cloth.

In order to achieve such an object, the present invention provides a first plate and a second plate provided with a diaphragm on the side opposite to the first plate, which are arranged alternately, and the second plate is arranged alternately. A first cloth is fixed so as to cover the surface of the diaphragm, and the first cloth is fixed to cover the surface of the diaphragm.
A second cloth is provided on both sides of the plate so as to be able to move back and forth within a predetermined length range, and an over-chamber is formed by the first and second cloths, and after running back and forth a predetermined number of times, the To provide a fully automatic multi-stage switching movable cloth dehydrator configured to move two cloths and make them reciprocate with a new surface portion.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a dehydrator main body according to an embodiment of the present invention, in which 1 is a vertical frame, 2 is a horizontal frame, 3 is a dehydrating mechanism supported by the horizontal frame 2, and 4 is a dehydrating mechanism provided below the dehydrating mechanism. Drainage pipe group, 5 is a compressed water supply pipe, 6 is a branch pipe provided above the dewatering mechanism, 7 is a link, 8 is a motor for driving the link, 9 is cloth, 10 is a winding shaft, 11 is a roller,
12 is a drainage tank.

FIGS. 2 to 5 are cross-sectional views showing the specific structure and operation of the dewatering mechanism 3. The dewatering mechanism 3 includes a first plate 13 and a second plate 13 provided with a diaphragm 15 on the side facing the first plate 13.
The first cloth 9A is fixed to cover the surface of the diaphragm 15 of the second plate 14, and the first cloth 9A is fixed to both sides of the first plate 13. A second cloth 9B is provided so as to be able to freely move back and forth between the winding shafts 10A and 10B within a predetermined length range. Note that 16 is a sludge supply port, and 17 is a drain port leading to the drain pipe group 4.

In the above configuration, first, the first
The sludge 1 is fed through the supply port 16 into the chamber formed by the second cloth 9A and the second cloth 9B.
Supply 8. Subsequently, by supplying compressed water into the second plate 14 through the branch pipe 6 shown in FIG. 1, the diaphragm 15 is expanded as shown in FIG. 3, and the sludge 18 is compressed. As a result, the sludge is dehydrated and filtered to form a cake, and the dehydrated water is drained from the drain port 17. 19 is a space formed by expansion of the diaphragm 15.

Next, as shown in FIG. 4, the first and second plates 13 and 14 are opened by the plate-opening mechanism, and the second cloth 9B is caused to run in the direction of the arrow, thereby causing the cake 20 to fall. At this time, the first cloth 9A remains fixed and does not run, but since the cloth on the diaphragm side generally has a property that cakes are difficult to adhere to, the cake on the first cloth 9A side can also be easily dropped. .

In addition, by choosing a cloth that is difficult for cake to adhere to, it is possible to further promote the falling of the cake.

Subsequently, as shown in FIG. 5, the second cloth 9B is returned to its original position by running along the side surface of the first plate 13 again, and as shown in FIG. 2, it is prepared for the next processing cycle.

The second cloth 9B repeats one reciprocating movement within a predetermined length range between the winding shafts 10A and 10B for each processing cycle.

As described above, according to the present invention, since one of the pair of cloths forming the overchamber is fixed to one of the plates, the sludge can be easily supplied and the processing efficiency can be improved. I can do it.

Along with this, only the other cloth is run along the side of the other plate, which simplifies the cloth supply mechanism, and also makes it easier to replace the cloth, improving the operating efficiency of the device. can be done.

Furthermore, even if the cloth on the traveling side becomes clogged, the simplified feeding mechanism makes it easy to move the unused portions in the upper and lower positions manually or automatically, making it possible to use this new surface portion. can.

Even on the fixed side, the cloth can be fixed with buttons or the like, so it can be easily replaced.

Furthermore, the fabric can be run without contact between the back and front sides.
