Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertical feeder for ceramic raw materials that stores ceramic raw materials to be used for molding tiles, bricks, etc. and sequentially feeds them from the matured raw materials.

Conventionally, as such a feeder, a certain caterpillar type feeder is known, in which a caterpillar that drives in a predetermined direction is arranged at the bottom of the storage part. Because the mechanism to ensure that the old raw materials are fed sequentially is insufficient, new raw materials that are not fully matured may be mixed in and fed, causing various problems in subsequent molding processes, etc., and the amount of raw materials fed may be reduced. This becomes unstable due to changes in the amount of raw materials in the storage section, which has been a hindrance to process control on fully automated production lines.

Furthermore, the moisture content of the raw materials charged into the storage section is not constant, and various troubles tend to occur during the drying process after molding, so it has been desired to adjust the moisture content during the storage stage.

In view of these drawbacks, the present invention aims to eliminate the above-mentioned drawbacks by making it possible to adjust the water content of the raw material while sequentially giving a kneading effect to sufficiently mature fortune-telling raw materials using kneading blades and dispensing blades provided in a rotating drum. An example of carrying out the present invention will be described below based on the drawings. 1 is a main body of a vertical feeder for ceramic raw materials according to the present invention;
A support shaft 3 is vertically fixed to a machine base 2 forming the base thereof, and a canine gear 4 is rotatably fitted into the support shaft 3.

Reference numeral 8 denotes a conical or flat plate-shaped bottom plate, which is placed and fixed on the dog gear 4 by being fitted into the support shaft 3, and the lower end of a rotating drum 9 having a predetermined volume around the outer periphery of the bottom plate 8. The rotation of the bottom plate 8 and the rotary drum 9 can be controlled via the dog gear 4 by the operation of the drive section 5.

In addition, there are feed ports 10, which are opened in a lattice shape at several locations on the lower circumferential surface of the rotating drum 9 to feed the raw material A in the rotating drum 9.
