Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a washing tank used for washing juice raw materials with water or disinfecting them with a chemical solution in, for example, a juice manufacturing process, and particularly relates to It is characterized by simplifying the structure of the belt conveyor installed inside to further improve the efficiency of internal cleaning.

Conventionally, as shown in FIG. 4, solid materials such as juice raw materials supplied into a tank are conveyed into a liquid by a belt conveyor 21, and the materials that have been washed there are further conveyed by a belt conveyor 21. There is a liquid washing tank 22 that is automatically carried out of the tank, and water 23 or chemical liquid 24 is filled in the tank depending on the purpose. In this case, as shown in the figure, washing tanks 22 may be arranged in series and the solid material may be sequentially conveyed by a belt conveyor 21.

The interior of the washing tank 22 is frequently cleaned, but it is difficult to clean it if there are many fixed devices such as guide plates inside.
The interior is made as hollow as possible by simply disassembling the belt converter 21, which is an essential device, and a structure without a fixing device as much as possible is preferable.

For this purpose, the belt conveyor 21 shown in FIG. 4 is designed to be able to carry out most of the conveying operations from receiving solid materials to carrying them out without relying on a fixing device such as a guide plate.

By the way, if the solid material supplied into the tank settles to the bottom of the tank through the gaps between the various parts, the solid material cannot be carried out of the tank, and the solid material also impairs the agitation of the liquid in the tank. As a result, the liquid washing tank 22 cannot fully perform its functions.

Therefore, it is necessary to prevent solid materials from settling to the bottom of the tank as much as possible.
1, there is a problem that solid materials may accumulate at the conveyance start end located in the liquid or a gap may be formed leading to the bottom of the tank. By bending and exposing both ends from the liquid, a liquid leakage area 26 is formed which is covered by the container belt. In this way,
Since the supplied solid material is washed in the liquid leakage area 26, there are no discontinuities in the conveyance path of the belt conveyor 21 within the tank, and settling of the solid material to the bottom of the tank is suitably prevented.

In addition, the side plate 27 of the liquid washing tank 22 is provided with a window 28 that can be opened and closed in order to facilitate internal cleaning. It is designed so that it can be disassembled and reassembled.

Problems to be Solved by the Invention However, in the liquid washing tank 22 as described above, the belt conveyor 21 is bent by the belt guide wheels 25 and 25, and both ends thereof are exposed from the liquid. The structure is complicated, the manufacturing cost is high, and the work of disassembling and reassembling the belt controller 721 for cleaning etc. is also time-consuming.

Therefore, in view of the above-mentioned problems, the present invention is equipped with a belt conveyor that can suitably transport the solid material supplied into the tank to the outside of the tank without causing the solid material to settle to the bottom of the tank without bending the belt conveyor. The structure of a washing tank equipped with a belt conveyor according to the present invention is as shown in FIG. After washing the solid material supplied to the tank, the belt conveyor 7 sequentially transports the solid material out of the tank. The belt pulley 8 is disposed inside the recess 12 formed on the wall surface of the tank in the liquid, and one edge of the recess 12 and the upper con hair belt are set as close as possible, and the transport In order to maintain the conveying function of the belt conveyor 7 even if solid material is caught between the start end side belt sheave 8 and the conveyor belt, the conveyance start end side belt sheave 8 is pushed into the recessed portion 12 by a predetermined distance or more. It is characterized by:

The supplied solid material falls directly into the liquid and is properly washed, and the washed solid material in the first part is sequentially caught on the conveyor belt of the belt conveyor 7 and transported out of the tank in a placed state. be done.

On the other hand, some of the solid materials sink in the liquid and reach the upper edge of the recess 12 formed on the tank wall, but the upper edge of the recess 12 and the upper conveyor belt are as close as possible. , it is almost impossible for the solid material to settle to the bottom of the tank via the recess 12.

In addition, solid material may enter the biting position of the conveyance start end side belt sheave 8 from the drainage gap or side gap of the conveyor belt, and the solid material may be caught between the conveyance start end side belt sheave 8 and the conveyor belt. However, since the belt pulley 8 on the conveyance start end side is pushed into the recessed part 12 by a predetermined distance, the solid material is transferred to the conveyor belt on the conveyance start end side, as shown by the two-dot chain line in FIG. 3(a). Belt wheel 8 and recessed part 12
It is ejected toward the front side of the rotation by moving the position appropriately between the upper edge of the Therefore, the belt conveyor 7 suitably maintains its function without causing problems such as rotation of the belt sheave 8 on the general feed start end side being blocked by the solid material.

Since the conveyance start end of the belt conveyor 7 can be provided in the liquid in a state that can prevent the solid material from settling to the bottom of the tank, the overall shape of the belt conveyor 7 can be configured to be approximately straight. This makes it possible to eliminate the need for belt guide cars.

Effects of the Invention As described above, according to the present invention, the overall shape of the belt conveyor can be made substantially straight without impairing the function of the belt conveyor to carry out the solid material out of the tank, thereby improving the belt guide of the belt conveyor. The structure of the belt conveyor is simplified by eliminating the need for wheels, etc., and as a result, the manufacturing cost of the liquid washing tank can be reduced.Furthermore, disassembly and assembly of the belt guide car is no longer necessary, so it is easier to clean the inside of the tank. This has advantages such as making maintenance management easier.

Embodiments Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a liquid leakage device used in a juice manufacturing apparatus embodying the present invention, and shows a structure in which liquid washing tanks are arranged in a continuous manner.
It is complete.

Each washing tank is filled with liquid 1, the liquid is sucked in by a pump 2 through a suction port 3 through a filter 4, and the pressurized liquid is ejected from an upper outlet 5 and a lower outlet 6 to stir the liquid 1. I have to.

In addition, a substantially straight belt conveyor 7 is installed obliquely in the tank.
The conveyance starting end side is submerged in the liquid 1, and the other end side is exposed from the liquid 1 and faces the next conveyance point. 8.8 is a belt pulley for rotating a net-like conveyor belt, and as shown in FIG. An openable/closeable window 10 for assembly is provided, and the belt pulley 8 is attached to a side plate 9 facing a support ring fixed to the back side of the openable/closeable window 10.
It is supported by a hole drilled in a screw body fitted with a nut fixed to [1]. Although FIG. 2 shows the belt pulley 8 on the driven side, the belt pulley 8 in the driven example has the screw body replaced with a drive shaft so that the rotation can be transmitted between the drive shaft and the belt pulley 8. It can be configured as appropriate.

Reference numeral 12 denotes a recess formed in the wall of the tank located in the liquid 1, and the belt pulley 8 on the conveyance starting end side is disposed inside the recess. It is important to fix this belt pulley 8 at a position that is pushed in a certain distance or more from the tank wall surface, and the edge of the recessed part 12 and the upper con hair belt are set as close as possible to each other. First, the pushing distance from the tank wall surface is too small. The solid material that has entered is caught between the belt pulley 8 and the conhair heald, and as shown in Fig. 3(b), the solid material is not released forward in the direction of rotation, so it gradually accumulates and eventually This will prevent the belt pulley 8 from rotating. Therefore, if the distance is increased, the distance between the belt pulley 8 and the upper edge of the recessed part 12 increases, and the conveyor belt can freely move up and down between them. As shown in Figure (a), the belt pulley 8 is appropriately ejected forward in the rotational direction, and the belt pulley 8 is not prevented from rotating. Next is the mutual distance M between the upper edge of the recessed part 12 and the upper conveyor belt, which is determined by the distance M between the upper edge of the recessed part 12 and the upper conveyor belt. The upper limit should be set so that it does not pass through, and the lower limit should be set so close that it does not damage the conveyor belt.

A gap 13 is provided between the inner surface of the recessed portion 12 and the belt pulley 8, so that even if solid material enters this portion, it will fall downward.

With the above configuration, when cleaning the interior of the washing tank, first open the openable window 10.10, pull out the belt pulley 8.8 to the side, and then pull out the other parts to the top. Then, since there are no obstacles such as guide plates inside, the interior becomes almost hollow and can be easily cleaned.
