Abstract

PURPOSE:To enable a structure strengthened in machine frame and roll by constituting in a body separate from a main body a machine frame and filter cloths of a squeeser provided at the terminal end part of pressing means in a belt press for performing a pressure dehydration of sludge between a pair of filter cloths. CONSTITUTION:In a belt press for performing a pressure dehydration of a sewer sludge between a pair of vertical filter cloths wound freely among numerous paralleled rolls, the frame of a squeeser A provided at the terminal end part of a pressure means and a filter cloths 1, 1 are constituted in a bode separate from a main body B. The squeeser A is constructed to squeese a sludge in two steps with a mesh belt 2 brought into contact with squeesing rolls 3, 3' and is driven by a belt 4 from the side of main body B. A belt press robustly constituting the frame of a squeeser and rolls on which a powerful force is applied is thus obtd.

Conventionally, between a large number of parallel rolls, a double-A1 θ1 IJ was routed along the running line, and the sewage water supplied between these b1 cloths was dewatered by drooping force.・Start with pressure with the above rolls, and then apply pressure with the seventh final stage of pressure V, and then press with the pressing belt 7.

On top of that, there are 9 points that will make the production cost more profitable.

るように構成している。This invention was developed in view of the above-mentioned difficulties in this type of press.This invention will be described in detail below with reference to FIG. 1 in Attachment 1. First, to explain its structure, as shown in the figure, a pair of upper and lower P fabrics are freely runnable between a large number of parallel rolls, and these pairs of '/
In a belt press configured to supply sewage sludge to J and perform pressurized dewatering, the machine frame and furnace cloth 1, 1' of the squeezing device A provided at the end of the pressurizing means for sludge are installed. It is a separate body from the main body B.The compression belt 2 used in the compression device A
is a wide rlJ menshube /l/ as shown in Figure 2.
) is used, and in the illustrated example, this mesh belt is brought into contact with two pressing rows/L'3.3, and is configured to be compressed in two stages.

It falls onto the lower cloth 1 of the pressing device A, and as the lower cloth 1 moves, it is sandwiched between the upper cloth 1 and sent to the pressing section.
Around the squeeze row/l'3.3, the water is further compressed and dehydrated by the squeeze belt 2 and discharged from the left end of the machine body.

A huge pressure is applied to , 3, and this squeezing row/
The 'IP4Ji1゜1 wrapped around the l'3.3 also has a huge surface pressure, and a huge tension is generated in order to make it run, but in this development, each part In addition, since the pressing device A, which generates such a powerful force for 71 seconds, is constructed separately from the main body B, it is possible to construct the machine frame and rolls sturdily. l, 1'
Even if you choose, it is best to choose km with an emphasis on strength. In other words, the cake sent to the presser A section is softened and dehydrated compared to the sludge supplied to the pressurized dewatering section, and its amount has been reduced to approximately r1], which is approximately equal to the width of the machine frame (- 77E cloth) may also be narrower than the pressurized dehydration section, and even if it is 1, 1', the pressing device A
This is because Li4j should be selected with a focus on strength that can withstand strong pressure rather than filtration.

このような従来の難点を悉く解消したものである。The conventional ridge belt plain has a gravity dehydration zone, a pressure dehydration zone, and a pressure dehydration zone. The dehydration zone is constructed in one machine frame, and the P cloth used is rarely the same, so there are unreasonable points in terms of equipment construction and excessive dehydration. There have been many, but this invention is
All of these conventional difficulties have been solved.
