Abstract

PURPOSE:To simplify the supply mechanism of a filter cloth, to facilitate the exchange of the filter cloth, and to improve the availability factor by arranging a filter plate provided with a freely reciprocating filter cloth on both side surfaces and a filter plate furnished with a filter cloth fixed to the side surface through a diaphragm alternately opposite to each other. CONSTITUTION:A filter cloth 9B capable of being reciprocated in a specified range of length by winding shafts 10A and 10B is provided on both side surfaces of the first filter plate 13, and the second filter plate 14, on whose side surface opposed to the filter plate 13 a diaphragm 15 and a filter cloth 9A covering the diaphragm 15 are fixed, is arranged. A filtration chamber is thus formed between the filter cloth 9A and 9B to constitute a dehydration mechanism 3. Sludge 18 is supplied from a supply port 16, pressurized water is supplied to the second filter plate 14 to expand the diaphragm 15 and to press said sludge 18, and the water generated in dehydration is discharged from a water discharge port 17. A cake 20 is dropped by opening the space between the filter plates 13 and 14 and traveling the filter cloth 9B in the direction as shown by the arrow. Then the filter cloth 9B is returned to the direction as shown by the arrow or exchanged, and the filter plates 13 and 14 are assembled to continue dehydration.

Description

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

As this dehydrator, there is known a type of dehydrator that utilizes squeezing force and is called a filter press.

For example, a first fabric with a diaphragm on both sides and a first fabric covering the surface of the diaphragm, and a second fabric with a second fabric on the side facing the xf) filter fabric mentioned above. A filtration chamber is formed by the first and second f-cloths by alternately arranging the second filter plate and the second f-cloth, and after supplying sludge (non-processing II stock solution) into this f-filtration trap, Compressed air is sent into the first PEA to inflate the diaphragm and the first filter cloth is moved into the second PEA.
The sludge is dehydrated and formed into a cake by narrowing Fmj by bringing it close to the f cloth of X, S
Ru.

Next, the first and second FIEs are opened, one cake is discharged, a new filter is formed, and sludge is supplied, thereby repeating the same dewatering process.

By the way, in such a conventional dehydrator, the first and second cloths forming the filtration chamber are both run on the sides of the first and second P plates, which makes the filter cloth supply mechanism complicated. 1. When fully automated, it is inevitable that the device structure will become complicated. .

Moreover, the work of changing the f cloth again becomes complicated, which causes a decrease in the operating efficiency of the apparatus.

The present invention has been made in response to the above-mentioned problems.
A filter is constructed in which one of a pair of filter cloths forming a filtration chamber is fixed to one filter plate, and only the other filter cloth runs on the side surface of the other Fi plate, thereby eliminating the drawbacks of the conventional filter. The object of the present invention is to provide a fully automatic multi-stage switching mobile dehydrator for cloth.

In order to achieve such an object, the present invention provides a first Pl
fl and a second f-plate provided with a diaphragm on the side facing the first f-plate are mutually arranged, and the second
A No. 1 filter cloth is fixed to cover the diaphragm surface of the P plate, and a second F cloth is provided on both sides of the first F & so that it can freely move back and forth within a predetermined length range. A filter chamber is formed by the first and second filter cloths, and after reciprocating a predetermined number of times, the second filter cloth is moved and the filter cloth is reciprocated with a new filter surface portion. This is a fully automatic dehydrator.

Below, we will explain the process of the present invention with reference to the drawings. @Figure 1 shows the main body of the dehydrator according to the present invention. 4 is a drainage pipe group provided below the dehydration mechanism, 5 is a compressed water supply pipe, 6 is a branch pipe installed above the dehydration mechanism, 7 is a link, 8 is a link drive motor, 9 is r cloth, 10 is a winding shaft, 11 is a roller, and 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 dehydration mechanism 3 is the first F@
13 and a second P plate 14 with a diaphragm 15 provided on the side facing the first F temporary 13 have an S structure arranged in a pomelo shape, and the diaphragm 1 of the second F plate 14
5! ! l! The first f cloth 9A is fixed so as to cover the surface, and a second f cloth 9A is fixed to both sides of the first P plate 13 so as to be able to freely move back and forth between the winding shafts 10A and 108 within a predetermined length range. r
A cloth 9B is provided. In addition, 16 is the sludge supply port,
17 is a drain port leading to the drain pipe group 4. , 1 In the above configuration, first, as shown in FIG.
The sludge 18 is supplied through the supply port 16 into the filtration chamber formed by the second filter cloth A and the second filter cloth 9B and K. Subsequently, by supplying squeezed water into the second Plfl4 through the branched vibro in FIG. 1, the diaphragm 15 is expanded as shown in FIG. 3, and the sludge 18 is squeezed. As the sludge is dehydrated, it is treated as 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 r+51fIi mechanism opens the space between the first and second P plates 13 and 14, and the second filter cloth 9B is run in the direction of the arrow, thereby causing the cake to fall. At this time, the first filter cloth 9A remains fixed and does not travel, but cake does not generally adhere to the filter cloth on the diaphragm side.

The cake on the first filter cloth 9A side can also be easily dropped.

By choosing a filter cloth that is difficult for the mata cake to adhere to, it is possible to further promote the falling of the filter cloth.Next, as shown in FIG. 5, run the second filter cloth 9B again on the side of the first P plate 13. This returns the original value to 11eK and prepares for the next processing cycle as shown in FIG.

No. 2 above. The filter cloth 9B repeats one reciprocating movement within a predetermined length range between the winding shafts 10A and 108 for each processing cycle.

As described above, according to the present invention, since one of the pair of filter cloths forming the filter chamber is set to have the same Pa as the other, sludge can be easily supplied. Processing efficiency can be improved.

Along with this, only the other filter cloth is run along the side of the other P plate, so the F cloth supply mechanism can be simplified, and the filter cloth replacement work can be done easily. The operating efficiency of the device can be improved.

Furthermore, even if the f cloth on the traveling side becomes clogged, the unused portions in the upper and lower positions can be moved manually or automatically thanks to the simplified feeding mechanism. This new filter surface portion can be used because it is easier to sip the tllI.

The filter cloth on the fixed side can be fixed with buttons, etc., so it can be easily replaced.

Furthermore, the filter cloth can be run without contact between the farm and the surface.
