たフィーダー装置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a feeder device for feeding powder or a mixture of liquid and powder in metered quantities. In more detail, for example, there are adhesive materials such as heated and kneaded mixtures of tar or pitch and carbon powder, or mixtures of ceramic raw material powder and binder, which are also subject to intermittent delivery of fixed amounts under temperature-controlled conditions. The present invention relates to a feeder device suitable for carrying out various operations.

工程に送るようにしている。Structure of conventional examples and their problems Conventionally, in the case of this kind of mixture, for example, a mixture of carbon powder and tar, which are the raw materials for obtaining carbon products through a molding process and a firing process, conventionally, the powders were mixed once using a stirrer. In many cases, the raw materials are processed in batches by adding liquid raw materials and kneading them. In the next process, since it cannot be processed all at once, it is stored in a housing bar and then sent in fixed amounts to the next molding process using a conveyor device or a screw feeder.

より作動しない。Such conventional examples have the following drawbacks, and a solution to these problems has been desired. In other words, in the case of the former combination of a hopper and a conveyor device, (1) it is difficult to send out a fixed amount and lacks quantitative properties; (2) Dust and gas may be generated from the conveyor equipment, contaminating the equipment and the environment. (3)
If a large amount of mixture is placed in the hopper, the conveyor will not operate due to the weight.

全に詰まりやすい、などの問題がある。There are other inconveniences. In the case of the latter combination of a pumper and a screw feeder, (1) it is easy to feed a certain amount, but clogging occurs frequently in the case of raw material mixtures that tend to adhere to the screw. (2) If the hopper and the screw casing are directly connected, the raw material mixture from the hopper will form a bridge or stick together due to its own weight, causing the raw material to clog at the joint. (3) Once the material becomes stuck inside the screw, the stuck object becomes more and more aggressive, and there is a problem that the inside of the screw is easily clogged completely.

1b is installed to rotate in the opposite direction. Casing 6
has an upper opening 7 and is connected to a lower opening of the hopper 8. The hopper 8 is provided with a rotating shaft 9 therein, the rotating shaft 9 has a Z-shaped blade 1O, and is connected to an external drive source 11. As shown in the cross-sectional view of FIG. 2, the screw 1 is a parallel biaxial screw 1a.

る。Further, the screw 1 has a hole in its shaft center, a heater or heat pipe 16 is set therein, and a jacket 16 is provided on the outside of the casing 6, so that a heat medium 17 for heating or cooling can flow through the jacket. There is. Note that the blades of the screw 1 are provided from just below the upper opening 7 of the casing 6 to just before the outlet 14. Further, a jacket 16' is provided around the outer circumference of the hopper 8 to allow the heat medium to pass therethrough.

持される。Next, to explain this operation, first, the raw materials 18 that have been mixed and stirred in advance are charged into the hopper 8 all at once. The raw material mixture 18 falls little by little into the upper opening 7 of the casing 6 by vanes 10 provided on a rotating shaft 9 that is rotated at a low speed by a motor 11. Screw 1
When rotated by the motor 4 which is an external drive source, the raw material mixture 18 flows from the opening 7 to the pitch part 12 of the screw 1.
The liquid enters the liquid 9, passes between the screw groove and the gap 19 between the two screws, and is sent to the outlet 14. At this time, the temperature of the raw material mixture 18 is maintained constant by the heat medium 17 flowing in the jacket 16 provided outside the hopper 8.

まったり、スクリュウ１に固着し難い。Further, since the blade 1o stirs the raw material mixture 18, the bridge of the raw material mixture 18 in the hopper 8 is broken. Inside the casing 6, the raw material mixture 18 placed in the hopper 8
Because the entire weight of the material is not applied to the screw 1 due to the presence of the blades 10, the raw material mixture 20 on the inlet side of the screw is less likely to solidify or stick to the screw 1.

In the intermediate gap 19, the raw material mixture 20 is pushed by the screws 1a and 1b, crushed and swept toward the outlet 14 as the screw shaft rotates. If the dimensions of the screws 1a and 1b are selected such that they overlap each other's blades, the performance of disintegrating the raw material mixture 2o and forcing it toward the outlet 14 will be improved.

. When Pi<Po, the raw material mixture 20 that has entered the inlet side is pushed forward as the screw rotates and moves into a wide space.
Difficult to adhere to. In particular, when the raw material mixture 1B has thermoplasticity, if the heating medium 17 in the jacket 16 and the heater 16 of the screw 1 are kept heated to keep the temperature conditions constant, it may easily adhere to the screw 1 and the casing 6. However, when Pi<Po, the degree of adhesion is significantly lower than when p, -po.

Heating and cooling of the screw 1, the casing 6, the jacket of the hopper 8, etc. may be unnecessary for the raw material mixture 18.

て出口１４に導かれ、定量で送り出される。In the feeder device of the present invention, since the blade 1o is provided in the large hopper 8, there is no solidification of the raw material in the hopper 8 or clogging at the outlet lower of the hopper, and the raw material at the inlet side of the screw 1 is prevented from solidifying. 18 crushing does not occur. Further, the above-mentioned raw material is passed through the screw in its unraveled state and guided to the outlet 14, where it is sent out in a fixed amount.

着した原料が分断され、定量性が長期間維持できる。By having two screws, even if something sticks to the screw inside the casing, it will be separated by the other screw, and as a result, clogging inside the casing will be less likely to occur. By setting the pitch of the screw to Pi<Po, the adhesion is significantly reduced, constant feed 9 is maintained for a long period of time, and maintenance is not required. In addition, the temperature of the hopper, casing, and screw can be maintained using a heat medium, etc., and it is possible to feed the raw material mixture in a fixed quantity while maintaining its quality. Furthermore, when the screw blades are overshipped, the raw material once attached is separated, allowing quantitative performance to be maintained for a long period of time.
