Abstract

PURPOSE:To easily discharge the whole quantity in a storing chamber by forming an annular measure-like space from the back surface of a rotary table, partitioning wall, bottom plate of a storing chamber, and the side wall of a cylinder part and installing a scraper onto the back surface of the rotary table and opening a part of the advance side partitioning wall and allowing said opened port to communicate to a discharge port. CONSTITUTION:An opened port as a discharge port 4 is formed at the center part on the bottom wall of the lower part cylindrical part 2 of a storing chamber 1, and a drop port is formed onto a rotary table 5, and an annular side wall 6, opened port, and a scraper 9 suspending into an annular measure-like space 7 are installed onto the back surface of the rotary table 5, and the rotary table 5 is driven by a motor 13 built in a cone 12. Then, the powder material in the storing chamber 1 is introduced into the lower part cylindrical part 2, guided by the cone 12, and then dropped into the annular measure-like space 7 from the drop port, and discharged from a chute 25 through the opened port and the discharge port 4. Therefore, cutting-out from the annular measure-like space 7 of a constant quantity feeding storing chamber is permitted with the simple structure without transferring said powder material, and discharge of the whole quantity in the space 7 can be easily carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a powder feeder for supplying and discharging various powder and granular materials in fixed amounts from storage chambers, containers, etc.

(Prior art) A conventional powder feeder is equipped with a rotary disk at the bottom of the storage chamber so that a part of the rotary disk is exposed to the outside from the storage chamber, and an annular groove is provided in the rotary disk. The granular material is stored therein, rotated, and scraped out with a scraper on the outside to be discharged.

(Problems to be Solved by the Invention) This conventional powder feeder requires a stirring blade to fill the concave grooves of the rotary disk with the powder, and has the problem that it is difficult to discharge the entire amount.

(Means for Solving the Problems) The present invention aims to provide a powder feeder of a new concept that solves these problems with a simple structure, and its gist is that the lower cylindrical portion of the storage chamber is The center of the bottom wall or the outer peripheral side wall of the cylindrical part is opened to serve as the powder discharge port, and the outer peripheral wall is located above the bottom wall. A rotary table is provided with a powder droplet and an annular partition extending down to the bottom wall of the cylindrical portion on the back surface, and an annular cell is formed by the back surface of the rotary table, the partition wall, the bottom wall of the storage chamber, and the side wall of the cylindrical portion. A space is formed, and a scraper that hangs down between the folding intermediates is attached to the back surface of the rotary table, and a partition wall on the advancing side of the scraper is partially opened to communicate with the powder or granular material discharge port. It's in the feeder.

In addition, the number of openings for the powder/grain material falling port, scraper, and annular partition is 1.
Of course, there may be one or more locations.

(Function) In this invention, the powder and granules stored in the lower cylindrical part of the storage chamber fall from the powder drop opening of the rotary table and are filled in the annular cell space below, and as the rotary table rotates, F is the powder. The particle falling port moves and fills the entire fixed annular cell space.

- When the rotary table rotates, the powder and granular material filled in the annular cell space is scraped off by the scraper provided on the back of the rotary table and discharged from the opening in the partition wall, and is discharged from the powder and granular material discharge port provided in the cylindrical part. It is something that is discharged. In this way, the granular material falls without rotating and moving, and is scraped off at that position by the rotating scraper. The powder contained in the cylindrical part is stirred by the shearing force generated by the rotation of the rotary table and the impact of the powder falling from the droplet.

(Example) The embodiments shown in the drawings will be described in detail below.

First embodiment (see Figures 1 to 3) The first embodiment shown in Figures 1 to 3 has a powder discharge port in the center of the bottom wall (3) of the lower cylindrical portion (2) of the storage chamber (1). (4) is provided, and the annular partition wall (6) provided on the back surface of the rotary table (5) is provided on the inside. In the figure (the force is the annular cell space, (8) is the powder falling port of the rotary table (5), (
9) is a scraper, (IQ is an opening in the annular partition (6), (
12 is a cone, (13 is a motor built in the cone and removes the rotary table (5). (14 is a support stay of the cone (1), (1 is a unit).

In this embodiment, the powder and granules in the storage chamber (1) are guided by the cone (1) and are all introduced into the lower cylindrical part (2),
The powder falls into the annular cell space (7) from the powder drop opening (8) and is discharged from the opening (IQ1) through the powder discharge port (4).

Second Embodiment (See Figure 4.5) The second embodiment shown in Figure 4.5 includes an annular bulkhead (6) of a rotary table (5) and an opening (101 on the outside, and a storage space on the inside). An original cell space (7) is formed by the fixed vertical wall (l [i) on the chamber side, and the powder in the annular cell space (7) is discharged to the outside by a scraper (9).

The pond is similar to the @1 embodiment.

(Effects of the Invention) As described above, according to the present invention, not only can the powder and granules be cut out from the fixed quantity supply storage chamber without much movement with a simple 11°4 construction, but also the entire amount in the storage chamber can be easily discharged. .
