Abstract

PURPOSE:To enable more rapid filtration, by a method wherein a ring shaped idle filter segment are provided to the gap groove formed between ring shaped filter segments forming the filter body of a filtering zone in an idled form and the accumulation of a cake between the filter segments is eliminated to always clean the gap groove of the filter body. CONSTITUTION:A raw liquid is supplied from a supply port 11a to rotate all filter bodies 2, 2'. Water in the raw liquid is at first passed through a gap groove 27' between the filter segments 22' of a filtering zone B and discharged out of a system from a filtrate guide orifice 24' and a filtrate chamber 12. In this case, a cake is accumulated between the filter segments 22' to clog the guide orifice 24' but removed toward the outer periphery by an idle filter segment 26' to carry out filtration more rapidly. On the other hand, the cake filtered in the filtering zone B is sent to a dehydrating zone A by rotating the filter body 2' to remove the liquid component therein in the gap groove 27 between the filter segments of the filter body 2 and guided to a cake take-out port 11b. When the cake is filled between rows of filter bodies and the raw liquid is not issued from the cake take-out port 11 directly, a lid F is opened to discharge the cake successively.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention is a furnace that separates an aerosol/inorganic fine particle S suspension (hereinafter referred to as the stock solution) into water and fine particles, and dehydrates the fine particles to form laminated fine particles (hereinafter referred to as a cake). This relates to a rotating body filtration device.

The basic structure of this device has already been patented. Each body is made up of pieces centered around the axis of rotation, which are arranged in a straight line so that they intersect with each other.Due to its structure, the rotation of the furnace body cannot be made too fast, so The drawback was that it was slow.

The present invention is a fertilizing device that does not have such drawbacks, and will be described below with reference to the drawings.

In the processing chamber 11 of the processing box 1, which consists of a processing chamber 11 having a stock solution supply port 11a and a cake takeout port 11b, and an IT liquid chamber 12 having an f liquid discharge port 12a, two or more of the four bodies 2 described below are placed adjacent to each other. The four bodies 2 are arranged in two rows at appropriate intervals, and the central shafts 21 of the four bodies 2 are rotatably fixed to the side plates 10 and 10' of the processing chamber 11. The furnace row has a dehydration zone A on the side near the cake outlet 11b.
1 - The opposite side is the dehydration zone B, and the body rows of the dehydration zone A are arranged in a straight line, while the r body rows of the dehydration zone B are arranged in a non-linear manner (e.g. staggered or r body rows). The rows are expanded in one direction).

In the dehydration zone A, the 2 pieces 2 are stacked alternately or appropriately with 37 pieces 22 and 37 pieces of different diameters centered around the central axis 21, and in the j piece 22? J, which communicates with the liquid chamber 12, is provided with a six piece 22 and a fixing ring 25 with a gap t23.

In addition, the furnace body 2' of the filtration zone B has the above-mentioned
A ring-shaped looser piece 26' is provided between the t-pieces 22', which are the same as those of 2'. It is fitted with a. Also, two pieces 22 at the outer periphery of the distance t 23 (23")
The space between (22') is defined as a narrow groove 27 (27'). In addition, the symbol P in the figure is a sealing member that connects the door body 2 and the cake outlet 11.
(b) to prevent contact with the undiluted solution and the cake. F is a lid for one cake outlet, which is opened manually or automatically under certain conditions.

Here, the seven bodies 2 in the dehydration zone A shown above may also have a gap on one side, and the two body rows in the IR passing zone B may be arranged in a straight line (that is, the opposing R body rows are parallel). There may be.

In addition, a cleaning water supply port 3 is provided close to the side of each body 2 (2'), and pressure water is continuously or intermittently injected into each of the two pieces 22.
(22') through the filtrate chamber hole 24 (24') 2
The interstitial groove 27 (27') of the body 2 and the r liquid chamber hole 24 (
24') may be provided.

Further, a device S for adding a flocculant to the stock solution supplied to the stock solution supply port 11a may be installed.

Further, a means K for detecting the hardness of the cake may be provided at the cake outlet 11b and connected to the flocculant addition device S to automatically adjust the amount of flocculant added.

Further, the shape of the two pieces 22 (22') of each door body 2 (2') may not be circular but may be oval, square, rectangular, or star-shaped.

Next, the operation of the apparatus of the present invention will be described. First, the stock solution is supplied from the supply port 11a. At that time, the lid F was closed, and all 4
The body 2 (2') is rotated once by a separate drive (not shown). Therefore, first pass through the groove 27'' between the j furnace pieces 22'' of the 2-pass zone B, and connect the holes 9 to the liquid chamber hole U'' and f liquid chamber 12.
is discharged from the system. At that time, cake is stacked between the two pieces 22' and blocks the hole in the liquid chamber, but is it free? The cake is removed toward the outer periphery of the two bodies 2' by the piece 26'', which leads to faster filtration.The cake filtered in the filtration zone B is removed by the rotation of the furnace body 2'. They are sent to the dehydration zone A. There, the 4 bodies 2 r
The liquid is removed by the bran rs 27 between the pieces 22 and guided to the cake outlet 11b. Then, when the R body row is filled with Riko cake and the undiluted solution no longer comes out directly from the cake outlet 11b, the lid F is opened and the cakes are sequentially discharged.

Herein the invention achieves its purpose.

In the device of the present invention, by arranging two bodies with one loose piece, the groove between the two bodies is constantly cleaned with the rim as a through hole, so that faster f-passage is possible.

In addition, by combining the gap with a door body that does not have a piece, it also has the effect of widening the range of application of this device depending on the type of raw solution (that is, the type depending on the size of the fine particles).
