Description

[Detailed description of the invention] The present invention relates to a deposition device in a clay raw material aging facility, which is used to deposit clay raw materials used as raw materials for various ceramic products in circular shapes in arbitrary blocks.

Generally, clay raw materials used for various ceramic products are aged for a certain period of time to equalize the moisture content in the raw materials, and at the same time, the bacteria present in the raw materials are propagated, and their excreta are used to improve plasticity. The oldest raw materials are used sequentially, starting with those that have matured sufficiently.

However, as shown in Figure 4, clay raw materials have traditionally been stored in inexpensive natural piles in storage facilities, so in such storage facilities, old raw materials remain at the bottom of the piled raw materials, resulting in This is extremely inconvenient in terms of the basic usage cycle, in which raw materials are used sequentially starting from those with good ripeness, and it is not always possible to supply raw materials with stable properties, and there are various management problems such as being limited to natural aged grains. It had a point.

Therefore, as shown in Fig. 5, we set up piles in the building that are divided into multiple blocks by dividing walls, and by sequentially feeding clay raw materials into these piles and performing the aging operation, it is possible to store clay for a long time. There are also facilities for aging clay raw materials that allow the use of clay raw materials from old clay blocks that have been aged, but such built-up facilities require the construction of multiple storage areas, which makes the facilities more expensive than open storage facilities. It had the following drawbacks.

In view of these drawbacks, the present invention has a pole erected in the central part of the clay raw material accumulation area, and the base of the rotating conveyor placed above the accumulation area is connected to the pole through a frame. The frame is equipped with a drive motor that controls the rotation of the rotating conveyor to any rotational position around the pole, and above the base of the rotating conveyor, the frame has a hopper with an opening at the upper end. A pole is arranged as the center, a conveyor for feeding clay raw materials is placed oppositely above the feeding part of the hopper, and a trolley equipped with a guide plate for dropping clay raw materials is moved on a frame along the turning conveyor. In order to solve the above-mentioned drawbacks, an embodiment of the present invention is described below by providing a deposition device in a clay material aging facility in which the guide plate is freely installed and the guiding plate is placed on the upper surface of the conveyor belt of the revolving conveyor. 1 is a deposition device installed outdoors in a deposition section 2 for clay raw material M, and a pole 3 is erected in the center of the deposition section 2. A base 5 of a turning conveyor 4, which is disposed above and circulated toward the tip, is rotatably supported via a frame 6, and a center gear 7 fixed to the center of the pole 3 is attached to the frame 6. A drive motor 9 having meshing gears 8 is installed,
The turning conveyor 4 is rotated by the operation of the drive motor 9.
The rotation is controlled to any desired rotational position around the pole 3.

A balance weight 10 is fixed to the other end of the frame 6, and supported between a ring 11 rotatably fitted above the pole 3 at the tip of the frame 6 on the turning conveyor 4 side. wire 1
2 is set up.

13 is a hopper for charging clay raw material M;
The hopper 13 has legs attached to the frame 6 such that the input portion 14 at the upper end is placed in an open position with the pole 3 as the center, and the discharge port 15 at the lower end is placed at a position facing above the base 5 of the turning conveyor 4. The rods 16, 16a, . . . are arranged integrally, and rotated together with the frame 6 around the pole 3.

17 sequentially transfers the clay raw materials M brought into the hopper 1
This is a feeding conveyor 17 for feeding into the hopper 13, and a transfer end of the feeding conveyor 17 is positioned above and facing the feeding portion 14 of the hopper 13.

Also, on the frame 6 is a cart 1 which is movable along the turning conveyor 4 by a drive device 18.
9 is installed, and the clay raw material M is placed on the upper surface of the conveyor belt 20 of the turning conveyor 4 on the trolley 19.
A guide plate 21 arranged obliquely with respect to the transport direction of the
is attached so that the clay raw material M transferred by the rotating conveyor 4 is distributed to the left and right by the guide plate 21 and allowed to fall.

Note that the inclined state of the guide plate 21 is not limited to the dogleg shape for the purpose of falling to both sides, but may be configured by a single inclined plate that guides the fall to only one side.

In addition, when covering the deposition area 2, support wires 22, 22a are stretched from the base of the pole 3 at equal circumferentially divided positions to the upper end of the pole 3.
... may be used as a skeleton to cover the tent 23.

Next, to explain the operation of the deposition device in the clay raw material aging facility according to the present invention, a plurality of fan-shaped blocks 24, 24a... When the turning conveyor 4 is rotated and positioned above any block 24 and the clay raw materials M brought in by the feeding conveyor 17 are sequentially transferred from this state, the clay raw materials M are transferred to the feeding conveyor 17. The clay raw material M is sent to the deposition device 1 side by the transfer action of 17, and is sequentially dropped from the transfer end into the hopper 13 arranged around the pole 3. are sequentially sent onto the base 5 of the turning conveyor 4 through the discharge port 15 of the turning conveyor 4, and are sequentially transferred to the leading end by the transfer action caused by the operation of the turning conveyor 4.

Then, the clay raw material M sent sequentially on the conveyor belt 20 collides with the guide plate 21 of the trolley 19 that is stopped at an arbitrary position on the conveyor belt 20, and is supplied falling to the left and right by the guiding action of the guide plate 21. By adjusting the movement of the guide plate 21 back and forth along the turning conveyor 4 by the running action of the cart 19, a predetermined block 2 of the depositing section 2 is moved.
The clay raw material M is deposited to a predetermined height in the block 24, and the drive motor 9 installed on the frame 6 is operated according to the divided area of the block 24 to move the turning conveyor 4 at an angle corresponding to the block 24. By rotating the block 24, a predetermined amount of the clay raw material M is deposited in the fan-shaped block 24.

After the deposition operation on one block 24 is completed, each time a new clay raw material M is brought in, the turning conveyor 4 is intermittently rotated for the adjacent blocks 24a, 24b, etc., and at the same time, each block is By moving the guide plate 21 back and forth at a position above the blocks 24a, 24b, . . ., the clay raw material M is sequentially deposited on each block 24a, 24b, .

When using the clay raw material M, the clay raw material M is selectively taken out by a shovel loader 25 or the like from the blocks 24, 24a... in which the aged clay raw material M is deposited after a predetermined aging period and used. It is.

In short, the present invention has a pole 3 erected in the center of the clay raw material M depositing section 2, and the pole 3 has a base 5 of the turning conveyor 4 disposed above the depositing section 2.
is rotatably supported via a frame 6, and a drive motor 9 is attached to the frame 6 to control rotation of the rotating conveyor 4 to an arbitrary rotational position around the pole 3. Blocks 24, 24a, which are set in a fan shape in an arbitrary range, are deposited in a circular shape around the pole 3 by depositing clay raw materials M sequentially supplied by the transfer action of the conveyor 4 and the rotation action of the turning conveyor 4. In addition, above the base 5 of the revolving conveyor 4, a hopper 13 with an input part 14 at the upper end opened is arranged around the pole 3, and the hopper Since the feeding conveyor 17 for clay raw material M is placed oppositely above the feeding section 14 of 13, the clay raw material M sent from the outside is transferred to the base 5 of the turning conveyor 4 by the turning conveyor 4.
can be continuously supplied at any rotational position, and a cart 19 equipped with a guide plate 21 for dropping clay raw material M is movably installed on the frame 6 along the rotating conveyor 4. However, since the guide plate is placed on the upper surface of the conveyor belt 20 of the rotating conveyor 4, the clay raw material M falling and supplied by the rotating conveyor 4 is adjusted to a constant stacking height within each block 24, 24a... Therefore, according to the present invention, even if the clay raw materials M are stored in an open pile state, the piled clay raw materials M can be divided planarly into fan-shaped blocks 24, 24a... When used, it is possible to selectively use raw materials that have been sufficiently matured, and it is possible to easily manage the aging and properties of the clay raw material M used for molding various ceramic products, and the storage facility for the clay raw material M can be stored in an open area. It can be constructed with low equipment cost like the facility, and it can also be used in the same way as a building by covering the accumulation part 2 with a tent 23 as appropriate with the pole 3 as the center. The effect is enormous.
