後者の遠心脱水式は、遠心分離機に海砂等を入れ脱水し

法は、所要動力が非常に大きく、大量且つ連続処理用と
しては不向きとされている。One is the water sprinkling method, in which water is sprinkled directly from above onto the sea sand deposited on a sand transport ship or on land, and salt removal is carried out through natural dehydration (Al). However, in this water sprinkling method, 1 ton of sand is It requires approximately 0.4 rrr or more of water to remove salt, so it is difficult to apply it unless you are in an area with an abundant water supply in order to remove salt sufficiently. It has been pointed out that it takes a long time, up to 7 hours or more, and that it is difficult to maintain a constant salt removal efficiency in the upper, middle, and lower layers of the deposited sand. The first is a mechanical treatment method, which can be further subdivided into classification methods, centrifugal dehydration, etc. The former involves mixing a large amount of water with sand in a container and separating the sand by sedimentation. This method uses 1.3 to 1 ton of sand.
Since it requires more than 300 ml of water, it can only be carried out in areas with abundant water and drainage treatment facilities. or,
The latter centrifugal dehydration method involves putting sea sand or the like into a centrifugal separator, dehydrating it, adding water, and dehydrating and cleaning it again. However, this method requires a very large amount of power and is not suitable for large-scale, continuous processing.

（作用）
先ず、第１〜第２図において本発明の洗浄脱水装置の主
要な構成要件となる装置の説明をする。(Function) First, referring to FIGS. 1 and 2, the main components of the washing and dehydrating apparatus of the present invention will be explained.
１）濾過装置本体１：

。1) Filtration device main body 1: This is an endless belt, and continuous frames 2 are formed at both ends of the belt in the width direction to prevent particulate matter from scattering outside the conveyor. On the surface of the belt, there is a drainage hole 3 that penetrates the belt vertically at approximately the center in the width direction.
are provided in large numbers at predetermined intervals. Washing water from left and right water collection grooves 4 flows into this drainage hole 3. A filter cloth 5 is placed over the entire surface of the belt including the drainage hole 3 and the water collection groove 4 to prevent particulate matter from being sucked into the liquid receiving chamber 8 by air intake from the lower part.
２）層厚調整装置６： 図面では両端を軸受７で支えた填圧ローラの例を示す。2) Layer thickness adjustment device 6: The drawing shows an example of a pressure roller whose both ends are supported by bearings 7.

げることができる。This is to adjust the thickness of the powder and granular material layer on the belt to be approximately uniform after the powder and granular material carried in from outside the system is carried into the above-mentioned filtration device main body l via the carry-in conveyor 11 and the chute 12. It is a device that can also be used with water sprinkling if necessary. In addition, as a layer thickness adjustment device, there is also a screw type; a screw shaft perpendicular to the belt traveling direction is set at a predetermined height on the belt surface, and the pitch of the blades provided perpendicular to the shaft is adjusted. The center part is rough and both sides are dense, and the center part is used as a reverse winding blade to rotate and smooth the surface. ■Adjustment plate: An A-shaped metal fitting when viewed from above is adjusted to a specified height of the belt. There is a device that is fixed at approximately the center of the belt width and distributes the powder and granules on the belt to the left and right to the same thickness. If these are used individually or in combination, a uniform cleaning effect can be achieved over substantially the entire belt surface.
３）受液室８：

力で大きな風量が得られるようにした。3) Liquid receiving chamber 8: The liquid receiving chamber 8 is located below the filtration device main body 1 (upper belt conveyor), and is located at a position that matches the running position of the drain hole 3 of the belt. The pipe 9 is connected to a blower via a gas-liquid separator 10. Therefore, during operation, this chamber is in a reduced pressure state due to the intake air from the blower, and the outside air and moisture are strongly sucked downward through the powder and granular material and the filter cloth, allowing cleaning and dehydration to be carried out in a short period of time. It will be. In the case of a general filter, a vacuum pump is used, but in the case of the present invention, since it is necessary to pass a fast airflow through the layer of granular material, a blower is used to generate a large airflow with low power. I made it possible to obtain.

る。The idea of the present invention is not only to remove salt from sea sand, but also to neutralize it with water to which an acidic liquid has been added, for example, when the attached water contains basic components (the reverse may also be the case). Alternatively, it can be used for dehydration such as pulverization of blast furnace slag, so it can be used for washing and dehydration of all kinds of powdery substances.

Sea sand brought in from outside the system via the input conveyor 11 and the chute 12 becomes semi-fluid due to water sprinkling from the top, and a filter cloth 5 is placed on the surface and frames 2 are placed at both ends.
It is continuously supplied onto the belt of the filtration device main body 1 which has been formed. The belt is rotated and moved to the right in the drawing by a drive mechanism (not shown) via a pulley 18. The slightly uneven surface of the sea sand layer is made substantially flat by a layer thickness adjusting device 6 (a roll is used in the embodiment).

。Next, the washing is performed by spraying water (fresh water) from above, and the washing water is collected through multiple water collection grooves 4 carved in the width direction on the filter cloth and belt.
The liquid is sucked into the liquid receiving chamber 8 through a drainage hole 3 provided approximately at the center of the belt. This liquid receiving chamber 8 is appropriately partitioned in the length direction and is connected to a blower 13 via a gas-liquid separator 10 provided at the bottom of the chamber 8, so that it is in a reduced pressure state during operation. The moisture in the sea sand is strongly sucked downward along with the atmosphere. Sea sand that has been dehydrated is transferred to discharge conveyor 1.
4, they are sequentially transported out of the system. 15 is a circulation pump, 1
6 indicates a seal tank, and 17 indicates a water sprinkling mechanism. Naturally, fresh water is used for final cleaning, and the water used several times in the first half of the process is disposed of outside the system.

There is no variation in quality because the treatment is done with approximately the same layer thickness, and the amount of water used is about 1/2 compared to the water spray type.Also, by using a blower as a suction device, it is easier to use than conventional suction. The power cost was significantly reduced compared to the centrifugal type, and was less than 173 yen compared to the centrifugal type. Moreover, it requires almost no manpower to operate, consumes little water, and can continuously process a large amount of water, so it is a great invention that will benefit the industry.
