Description

[Detailed description of the invention] The present invention relates to a device for dehydrating a processed material by stacking endless belt-shaped rotating filter cloths one above the other. The purpose is to make it possible to increase the width to a large extent and to improve its dewatering performance.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

Drive section 2A, 2B with drive roll 1 and tension roll 3
A pair of tension sections 4A and 4B each having a The pair of drive parts and tension parts 2A, 4A, and 2B, respectively, are placed in such a state that the upper and lower parts are opposed to each other, and at the opposite locations.
, 4B are made to correspond to each other, one endless belt-shaped second rotary filter cloth 6, 7 is wound around the driven row/shield 8 and the tension part roll 9 degrees, and then the opposite pairs of rotary filter cloths are Cloth 5
．． With respect to 6.5.7, each tension roll 9 side is set as the upper side, and the supply part 10 of the material to be treated is provided on the upper side of each of the locations where the filter cloths face each other, and the dehydrated cake take-out part 11 is provided on the lower side. At the same time, a squeezing dewatering roll group A and a shearing dehydrating roll group B are provided, which act on the opposed filter cloths 5.6.5.7, respectively, and the water is collected on the back side of the filter cloth in the dewatering section of these rolls. A tank 13 connected to the water pit 12 is installed, a meandering correction roll 14 and a cleaning shower 15 are installed, and one first
While sharing the rotating filter cloth 5, a series of dehydration processes is carried out separately in the upper and lower three systems, and the drive parts and tension parts 2A, 4A, 2B, 4 are individually adapted to each system.
By setting the filter cloth tension according to B, a dewatering apparatus is constructed in which the dewatering performance in each system can be uniformly adjusted.

FIG. 2 shows a modified structure of the dehydration device, in which tension parts 4A and 4B are provided near the material supply part 100 in each dehydration treatment system for the first rotary filter cloth 5, and a drive part 2A , 2B are installed in the dehydration section of each dehydration treatment system.

In addition, in the dewatering device with this deformed structure, the tension part 4A
, 4B in the dewatering section and the drive sections 2A, 2B near the object supplying section 100. The arrangement of the drive sections and tension sections 2A, 4A, 2B, and 4B can be modified in various ways.

In summary, the dewatering device according to the present invention has one endless strip-shaped first rotary filter cloth opposed to a plurality of endless strip-shaped second rotary filter cloths, and filters at each location where the filter cloths face each other. A dehydrated cake take-out part is provided on the lower side in the right rotation direction, and each of the driving part and tension part for the first rotation filter cloth is connected to the filter cloth. It is characterized by the fact that there are a plurality of them, each corresponding to the opposite location.

In other words, as a means to increase the dewatering capacity, for example, ink can be used to dehydrate the filter cloth while it is being dehydrated, but there is a limit due to wrinkles in the filter cloth and the strength of the roll, and It requires a large installation space, and if multiple dewatering devices are placed side by side in the lateral force direction or stacked one on top of the other in the vertical direction, the equipment itself becomes large and requires a large installation space both in terms of plane and space. In this regard, by configuring multiple dehydration treatment systems using a single endless belt-shaped rotating filter cloth, the entire device can be made compact both in terms of plane and vertical space, while dewatering. It became possible to increase the processing capacity of.

It is conceivable to provide a pair of drive section and tension section for the first rotary filter cloth to simplify the drive device, but in multiple processing systems, the drive and tension of the filter cloth There is a risk that the dewatering performance may become uneven due to an imbalance between the Overall, this is an extremely simple improvement, and it has become possible to perform high-capacity dehydration treatment with good performance even though it is a small device.
