Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filter device, and more particularly to a filter device installed in a dewatering trunk recessed in the inner wall of a slurry cargo carrier.

Regarding dehydration filters used in coal slurry carriers, the specific gravity of coal is approximately 1, which is much smaller than 3.7 for iron sand slurry, so it is desirable to use a dehydration filter that is suitable for coal.

The purpose of the present invention is to provide a filter device for, for example, coal slurry, which has a low specific gravity, and also to provide a filter device that is easy to handle and inexpensive to manufacture.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

1 is a slurry carrier vessel. In the lower portions of the left and right side walls 2, 2 of the vessel 1, side dewatering trunks 3 are provided in a concave shape with a gentle downward slope toward the rear, and in the lower part of the rear wall 4, a mountain-shaped, i.e. A rear dehydration trunk 5 with a gentle downward slope from the center to the left and right is provided in a concave shape, and a plurality of vertical dehydration trunks 6 (three in this embodiment) communicating with the rear dehydration trunk 5 are recessed. It is set up in a shape.

Reference numeral 7 denotes a filter device provided at the openings 3a, 5a, 6a of each of the dewatering trunks 3.5.6 communicating with the inside of the ship 1.

The filter device 7 will be explained in detail with reference to FIGS. 3 and 4.

Although FIGS. 3 and 4 show the vertical dehydration trunk 6, the side and rear dehydration trunks 3 and 5 are also the same, so their drawings are omitted.

8 is the opening 3a, 5a, 6a of the dehydration trunk 3, 5, 6
A bolt 11 is attached to a mounting seat 10 fixed to both adjacent wall surfaces 9, 9.
It is made of, for example, a vinyl chloride synthetic resin plate attached through a hole, and has a porous shape with many through holes 8a drilled over substantially the entire surface.

Further, reference numeral 12 denotes a wire mesh supported on the front surface of the opening side of the synthetic resin plate 8, and the synthetic resin plate 8 is attached with bolts 11.

Note that 13 is a rubber gasket interposed between the mounting seat 10 and the synthetic resin plate 8.

14 is an opening 3a located in front of the wire mesh 12 on the opening side;
The pressure receiving plates 5a and 6a have a double plate structure made of steel plates, and are porous with a large number of through holes 14a drilled on substantially the entire surface thereof.

Further, the pressure receiving plate 14 is connected to the dewatering trunk 3. 5. It is removably guided and supported by a pair of groove-shaped guides 15 provided on both wall surfaces 9, 9 of 6.

The mounting wall surfaces of the guides 15 are provided, for example, on the upper and lower surfaces of the side and rear dewatering trunks 3 and 5, and on the left and right surfaces of the vertical dewatering trunk 6.

In order to allow the pressure receiving plate 14 to be attached to and removed from the guide 15 of the dehydration trunks 3, 5, and 6, the guide 15 is provided with a notch as shown in FIG. I'm trying to push it inside.

Reference numeral 16 denotes a step for lifting and lowering provided inside the vertical dewatering trunk 6.

According to the above configuration, when slurry-like pulverized coal is put into the ship 1, it is classified in a wide ship hold due to the difference in particle size of the pulverized coal, and coal with larger particle sizes accumulates at the bottom of the ship and on the inside wall of the ship. However, the opening 3a of the dehydration trunk 3, 5, 6,
The pressure receiving plates 14 provided at 5a and 6a substantially prevent pulverized coal from entering the dewatering trunk 3°5.6.

When deicing the slurry water, first operate the drainage pump (not shown), and the slurry water will be removed from the pressure receiving plate 14.
through the dehydration trunks 3, 5, and 6, but the pressure receiving plate
The slurry water that has passed through Step 4 contains some powdered coal.

However, this pulverized coal is effectively removed by the subsequent wire mesh 12, and only the slurry water is drained overboard from the dewatering trunks 3, 5.6.

Note that the pressure receiving plate 14 may be a pressure receiving plate 17 having a structure in which a plurality of ribs 17b are attached at an angle to the rear surface of a test plate 17a, as shown in FIGS. 5 and 6.

As described above, according to the filter device of the present invention, since the pressure receiving plate is separate from the wire mesh and is pushed in, the pressure receiving plate can be easily attached and removed, and therefore the wire mesh can be easily cleaned, maintained and inspected. can.

In addition, since a synthetic resin plate is used to support the wire mesh, the filter device is lightweight, easy to install and remove, eliminates the problem of rust on the wire mesh, and furthermore reduces the manufacturing cost. becomes significantly cheaper.

Furthermore, since the filter device is installed in the dewatering trunk, there is no need for a separate protective plate, and there are no protrusions into the ship's hold, making it easier to work inside the ship's hold.
