The scooping parts 4, . . . are ring plates 4b, 4 with holes 4a arranged in parallel on the inner peripheral surface of the drum 1.
It is constructed by disposing mesh plates 4c, . . . between b. Further, on the outer periphery of the drum 1, welded protrusions 5, . Reference numeral M designates a motor which is fixed to the main body frame 2 and rotates the drum 1 by driving a chain 7 that engages and disengages from the projecting piece 5.
The R group includes a deceleration motor, a pulley, and a guide roller. Reference numeral 9 denotes a chute arranged in the cleaning chambers Sb, Sc and the first separation chamber Sa, and the upper part 9a thereof is widened, and the upper end is connected to the chamber S, respectively.
Open □ at the top of a, Sb, Sc and the chute 9
, . . . are inclined so that the lower end discharge port 9b of the chute 9 faces from the center hole 3a of the wall plate 3 to the lower part of the adjacent cleaning chamber Sb.

However, the chute 9 of the outer cleaning chamber Sc is its outlet 9b.
' is connected to the outside of drum 1. Also, the first separation chamber S
A supply pipe 18 for supplying slurry raw material is introduced into a. Reference numeral 11 denotes an inclined plate fixed downward from the upper part 9a of the chute 9 in the form of a slant.

Reference numeral 12 denotes a vibrating conveyor placed in the second separation chamber Ka and the particulate cleaning chamber Kb, which is provided with guide plates 12a on both sides and whose discharge end faces the lower part of the adjacent particulate cleaning chamber Kb through the central hole 3a. I'm letting you do it.

However, the discharge row 2 of the conveyor blade 2' of the outermost cleaning chamber Kb
b is placed outside the drum 1. Reference numeral 13 denotes an inclined plate that is inclined downward from the guide plate 12a of the conveyor turtle 2.

14 is a water pipe, and cleaning chambers Sc on both sides of the drum 1,
Piping is provided so that water can be sprayed onto the upper ends of the chutes 9 and conveyors 12 other than the chute 9 and conveyor 12 placed in Kb.

Note that the chute 9, conveyor 12, and water pipe 14 are fixed to the frame 2 and do not rotate together with the drum. Further, 15a, 15b, 16 are coarse particle cleaning chambers Sc, Sb, respectively.
``This is a collection pipe that collects the overflowing slurry from the particulate cleaning chamber Kb, and is used as water for turning raw materials into slurry.17 is a discharge pipe for the slurry from which particulates have been removed.

Next, when using this example device, first the first separation chamber S
A slurry raw material obtained by turning ceramic raw materials into slurry is supplied to a from the supply pipe 10 until a certain water level T is reached, and the mallet grains are settled and classified.

Note that a baffle plate 18 is inserted to promote the settling effect of the hammer particles. When the motor M is driven in this state, the chain 7 is decelerated and engages the protruding piece 5 of the drum 1 to rotate the drum 1. As a result, all chambers Sa, Sb, Sc, K
Since the scooping parts 47 of a and Kb also rotate together,
First, the coarse particles (hereinafter referred to as silica sand in this example) that have settled in the first separation chamber Sa are scooped up by the scooping section 4 and lifted up. At this time, the muddy water flows out from the mesh of the scooping part 4 and the holes 4a, so that the silica sand can be drained. As the drum rotates, the scooping part 4 rises and becomes inverted, and the scooped silica sand naturally falls into the chute 9 as shown in FIG. Furthermore, shoot 9
The silica sand that falls outside falls onto the forehead swash plate blade 1 and falls again onto one of the scooping parts 4, and does not fall directly downward. The silica sand that has fallen into the chute 9 is washed by fresh water sprayed from the water pipe 14 in the form of a shower, and falls into the next washing chamber Sb. The operation of cleaning the cleaning chamber Sb' is also carried out by the same machine, in which the scooping section 4, . However, in the cleaning chamber Sc, since no cleaning water is discharged into the chute 9, only the cleaned silica sand is discharged from the discharge port gb' of the chute 9. Note that cleaning water accumulates in the cleaning chambers Sb and Sc, so when it exceeds a certain amount, it overflows and is guided out of the drum 1 through the respective collection pipes 15a, . . . and used as water for turning the ceramic raw materials into mud. are doing. On the other hand, in the first separation chamber Sa, only the silica sand, which is a granular material, settles, and the fine granular material, silica sand, is present in the slurry containing the silica. Therefore, from the central hole 3a' of the wall plate 3 to the second separation chamber K.
The only thing that overflows into a is mud and Kira.
In the second separation chamber Ka, the clay settles due to specific gravity separation, and the china clay water (which is dehydrated with clay slurry and becomes product clay) from which the clay is removed overflows from the discharge pipe 17 to the outside of the drum 1. and will be led to a tank (not shown). Note that the baffle plate 19 attached to the frame 2 improves the settling effect of Kira. Further, the sedimented debris falls onto the vibrating conveyor 2 by the scooping section 4, and is sent to the outermost cleaning chamber Kb while washing off the adhering clay with the cleaning water from the water pipe 14. be. In the washing chamber Kb, the waste separated from the washing water is dropped onto the conveyor 12' by the scooping section 4, and is discharged to the outside of the drum 1 from the discharge end 12b.
The overflowing mud from the cleaning chamber Kb is collected in the collection pipe 16.
The water is led out of the drum 1 and used as water for turning ceramic raw materials into slurry in the same manner as described above. As described above, according to this example, an epoch-making effect can be obtained in that silica sand, silica, and china clay water can be obtained from muddy ceramic raw materials simply by rotating the drum. In addition, the silica sand and dirt can be washed several times with one rotation of the drum, and there is no need to wash the obtained silica sand and dirt again. Although this example is configured as described above, the present invention is not limited to this. For example, the means for rotating the drum is not limited, and the number of coarse particle cleaning chambers and fine particle cleaning chambers divided into the drum is also limited. Not done.

Furthermore, regardless of the configuration of the scooping section, an appropriate delivery body such as a conveyor or chute for sending out the Kira can be adopted. In short, the present invention vertically divides the interior of the rotating drum into a classroom coarse particle cleaning chamber, a first separation chamber, a second separation chamber, and an appropriate number of fine particle cleaning chambers in this order, and the peripheral wall of each chamber. A number of scooping parts are installed around the inner peripheral wall of the drum, a means for supplying slurry raw material to the first separation chamber is provided, and a chute is provided with an entrance at the upper end of the drum to the first separation chamber and the coarse particle cleaning chamber. The outlet of the chute faces the adjacent coarse particle washing chamber, and the outlet of the chute of the outer coarse particle washing chamber is located outside the drum, and the coarse particles settled in the first separation chamber are A means is provided for guiding the slurry from which particulate matter has been removed to a second separation chamber, and a delivery body such as a conveyor having a closed upper end is provided in the second separation chamber and the particulate matter cleaning chamber, and the discharge portions of the delivery bodies are adjacent to each other. In addition to facing the particulate matter washing chamber, the delivery body of the outermost particulate matter washing chamber is placed outside the drum, and water is supplied to other chutes or delivery bodies other than the chutes or delivery bodies placed in the washing chambers on both sides of the drum. This is a sorting and separation apparatus for ceramic raw materials, which is equipped with a water supply means that can rotate the drum, a means for rotating the drum, and a discharge pipe that leads the slurry from which fine particles have been removed from the second separation chamber to the outside of the drum. Therefore, the classification of coarse particles such as silica sand, which was previously done in a separate process,
The process of classifying fine grains such as clay and separating muddy liquids such as china clay water in one step is highly effective, which reduces equipment costs, and is hygienic because it uses a closed rotating drum system. In addition, it is a revolutionary invention that has the advantage of being able to wash coarse particles and fine particles several times at the same time with one rotation of the drum, and is particularly suitable for sorting and separating ceramic raw materials.
