2. Description of the Related Art In order to form a granular raw material kneaded with an inorganic binder as described above, first the kneading machine is used to knead the granular raw material and the inorganic binder, and then this is lifted to the upper end of the hopper by a conveyor or the like. It is usual that the material is charged into the molding machine, further charged from the lower end of the hopper into the hopper of the molding machine by a chute or a vibration feeder, and then supplied into the molding die to mold into a block body or the like. However, in such a conventional molding machine, an adhesive kneaded material adheres to the inside of a conveyor, a hopper or the like to hinder the smooth supply of the kneaded material, and the adhering kneaded material dries again due to vibration or the like. There is a problem in that it is mixed in the kneaded product, resulting in deterioration of quality. Further, there is a problem that it takes a long time to discharge the remaining raw material and clean the inside at the end of the work for one day.

[0003]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and enables a granular granular material having tackiness to be smoothly supplied to the inside of a molding die, and dried deposits. The purpose of the present invention is to provide a molding machine for granular raw materials, which can prevent deterioration of quality due to mixing and can easily discharge and clean granular raw materials attached to the inside of a hopper or the like.

[0004]

SUMMARY OF THE INVENTION The present invention, which has been made to solve the above-mentioned problems, slides between a molding die installed below the table surface and a fixed hopper provided above the table surface. While the slide hopper that supplies the granular raw material to the forming die is provided on the table surface, and the kneading machine for the granular raw material is installed at the upper end of this fixed hopper, the granular raw material can be directly fed into the fixed hopper. It is a feature.

[0005]

The present invention will be described below in more detail with reference to the illustrated embodiments. In the embodiment of FIG. 1, 1 is a table surface, and 2 is a molding die installed below the table surface 1. Reference numeral 3 denotes a slide hopper provided so as to be slidable by the cylinder 4 along the upper surface of the table surface 1, and reference numeral 5 denotes a fixed hopper provided above the table surface 1. The slide hopper 3 is a frame-shaped bottomless one, and can receive the granular raw material from the lower end of the fixed hopper 5 and slide it along the table surface 1 onto the forming die 2 to supply the granular raw material therein. it can. In the embodiment, the slide hopper 3 and the fixed hopper 5 are installed on both sides of the molding die 2, and two kinds of granular raw materials, for example, a colored raw material for the surface layer and a non-colored raw material for the inner layer can be alternately supplied. You can do it.

At the upper ends of these fixed hoppers 5, kneaders 6 for granular raw materials are installed. Generally, such a kneading machine 6 is usually installed on the floor surface, but in the present invention, the kneading machine 6 is installed on the upper end of the fixed hopper 5. The kneader 6 is for kneading a granular raw material such as sewage sludge molten slag and an inorganic binder,
It can be tilted to both sides around the horizontal axis 7. As shown in FIG. 2, if the kneading machine 6 is tilted toward the fixed hopper 5, the granular raw material can be directly fed into the fixed hopper 5. Further, a washing water draining portion 8 is provided on the opposite side of the fixed hopper 5, and if tilted in this direction, the washing water inside the kneading machine 6 can be easily discharged. Although the type of the kneading machine 6 is not particularly limited, the formation of a dead zone can be prevented by selecting a kneading type in which the bottom portion is formed of an elastic material and the bottom portion itself is moved. It is possible and preferable.

[0007]

In order to carry out molding by the molding machine for the granular raw material of the present invention thus constructed, first, the kneading machine 6 installed at the upper end of the fixed hopper 5 and the granular raw material such as sewage sludge molten slag and the inorganic material are used. Kneading machine 6 after kneading with binder
As shown in FIG. 2, the kneaded granular raw material is charged into the fixed hopper 5 by inclining it toward the fixed hopper 5. Next, when the slide hopper 3 is moved to the lower end of the fixed hopper 5 as shown in FIG. 1, the granular raw material in the fixed hopper 5 enters the slide hopper 3. Therefore, when the slide hopper 3 is slid by the cylinder 4 along the table surface 1 to a position above the molding die 2, the granular raw material falls from the bottomless slide hopper 3 and is filled in the molding die 2. . Then, pressure is applied by the upper die 9 and the molding die 2
Is vibrated to form a block body or the like.

As described above, in the present invention, the kneading machine 6 is provided at the upper end of the fixed hopper 5 so that the kneaded granular raw material is directly supplied to the fixed hopper 5, and the granular raw material from the fixed hopper 5 to the molding die 2 is fed. Since the supply is performed by the slide hopper 3, adhesion to the surroundings can be reduced as compared with the conventional one. Moreover, during the molding operation, the kneading machine 6
If the inside of the machine is contaminated with the residual raw material, water is easily discharged by pouring water into the kneading machine 6 and stirring and tilting the kneading machine 6 toward the cleaning water drainage section 8. The work can be performed very easily and automatically without interruption of the molding operation.

[0009]

As described above in detail, in the granular raw material molding machine of the present invention, the granular raw material kneader is installed at the upper end of the fixed hopper so that the granular raw material can be directly charged into the fixed hopper. In addition, since the raw material is put into the forming die by using the slide hopper, the sticky granular raw material can be smoothly supplied into the forming die. Further, the kneading machine can be automatically washed even during the molding operation. For this reason, it is possible to prevent the deterioration of quality due to the mixing of the dried raw material adhering to the inside of the hopper or the like. Therefore, the present invention has an extremely great contribution to the industrial development as a molding machine for granular raw materials that solves the conventional problems.
