Description

[Detailed Description of the Invention] This invention relates to an improvement of a dewatered cake peeling device for a belt press that improves the peelability of sludge from the furnace cloth and prevents the peeled sludge from falling to the outside on both sides of the furnace cloth.

Conventionally, in a belt press dewatering cake peeling device, as shown in FIG. It ran along the rolls 4 and 5 while gradually separating the distance between the furnace cloths, and the dehydrated cake 7 adhering to the furnace cloth was scraped off by a scraper 6 that was in contact with each of the peeling rolls 4 and 5.

However, since the distance between the two distribution cloths 4 and 5 gradually increases, the dehydrated cake 7 tends to adhere to the upper furnace cloth 4, making it difficult to peel it off smoothly. 7 is scraped off by the scraper 6, and when removed, the peeled sludge falls down on both sides of the lower furnace cloth 5, which is a drawback.

The object of this invention is to provide a belt press dewatered cake peeling device which eliminates the above-mentioned drawbacks, improves sludge peeling properties, and prevents peeled sludge from falling to the outside on both sides of the furnace cloth.

An embodiment of this invention will be described below with reference to the drawings.

As shown in the schematic vertical sectional view of the stripping device in FIG. After dewatering the sludge and passing through the compression roll 13 located at the final position of the dewatering process, the sludge is passed through the stripping rolls 14 and 1.
The direction of travel is changed by 5.

The peeling rolls 14 and 15 are pivotally supported by a frame 16 for supporting the belt press, as shown in the cross-sectional views of the peeling rolls in FIGS. As shown in FIG. 2, the upper furnace cloth 11 is provided at a downwardly sloped portion, and the running surface of the lower furnace cloth 12 is provided so that the upper furnace cloth 11 and the lower furnace cloth 12 run almost parallel to each other. Proximally supported.

Further, the peeling roller 15 for the lower oven cloth is provided at a portion where the lower oven cloth 12 runs straight.

A scraper 17 having a blade for removing sludge is installed in contact with each of the peeling rolls 14 and 15, and the scraper 17 is formed to scrape off the dewatered cake 18 adhering to the furnace cloth surface.

Further, as shown in FIGS. 2 and 3, on the inner wall of the frame 16 for supporting the belt press and at a position below the peeling roll 14 for the upper furnace cloth 11, there is a pocket portion 19 for capturing fallen peeled sludge. A window 20 for cleaning is formed.

Next, the operation of this invention will be explained.

After the upper oven cloth 11 and the lower oven cloth 12 pass through a compression roll 13, their running directions are changed by peeling rolls 14o and 15, respectively.

At this time, both peeling rolls 14 and 15 remove the dehydrated cake 1 that has adhered to the surface of the furnace cloth by changing the running direction of the furnace cloth.
Perform step 8 peeling.

Here, in particular, the peeling roll 14 for the upper furnace cloth 11 is attached to the lower furnace cloth 1 so that both the distribution cloths 11 and 12 run parallel to each other.
The upper furnace fabric peeling roll 1
Since the lower furnace cloth moves as it is at the position 4, the rapid reversal of the upper furnace cloth 11, the force to maintain the sludge form, and gravity are organically combined, and the dewatered cake 18 is peeled off. The effect is greatly improved, and the dehydrated cake 18 hardly adheres to the upper furnace cloth 11, so that the peeling operation can be carried out smoothly.

Moreover, since the peeling roller 14 is pivotally supported in close proximity to the lower furnace cloth 12, almost no peeled sludge 21 falls down on both sides of the lower furnace cloth 12.

Furthermore, even if it falls to the outside of both sides of the lower furnace cloth 12, it will be surely captured by the pocket portion 19, and for example, at the end of the operation, cleaning water can be supplied and the fallen peeled sludge 21 can be discharged to the outside. .

For this reason, it is preferable to provide a washing water injection supply means at the top of the pocket portion 19 and a washing water discharge means at the bottom end.

Further, it is preferable to provide a cleaning window 20 throughout the frame so that a brush or the like can be inserted therein.

FIG. 4 shows another embodiment of the pocket section 19, which has an inclined shape with respect to the frame 16 and has a structure in which the captured exfoliated sludge 21 can be automatically discharged to the outside.

The structure and installation location of the pocket section 19 are not limited as long as it can capture the peeled sludge 19 scattered to the outside of both sides of the lower furnace cloth 12.

As described above, the dewatered cake stripping device of this invention has extremely excellent practical effects such as significantly improving the sludge stripping effect from the furnace cloth and preventing the peeled sludge from falling downward on both sides of the furnace cloth. is obtained.
