Description

  In the present invention, the granular material stored in the hopper is smoothly discharged to the discharge port through the annular passage provided in the outer peripheral portion of the supply disk while supplying the powder on the supply disk that is rotationally driven. In the configuration, by setting the space area that forms the angle of repose of the granular material with respect to the annular passage on the supply disc, it is possible to handle the granular material having various physical properties or property changes, respectively. The present invention relates to a granular material supply apparatus having excellent versatility.

  Conventionally, as an invention according to the present applicant, for example, in various powder supply devices such as a table feeder, a vibratory feeder, a screw feeder, and a rotary feeder, depending on the type of powder to be sent, it is impossible or impossible to send. It can be very difficult, or the amount of powder in the delivery container can vary greatly, resulting in a significant difference in the amount of powder delivered per hour due to the difference in the bottom pressure based on its weight. From the viewpoint that it is difficult to quantitatively supply fine powder particles, it is generally difficult to supply a relatively small amount of fine powder, wetting material amount, dehydrated cake, pigments, dyes, other adhesive powder particles, etc. On the other hand, we have proposed a powder quantitative delivery device that can smoothly and appropriately supply a reliable quantitative powder, and obtained a patent and achieved its practical application (Patent Document) Reference).

  That is, as shown in FIG. 9 and FIG. 10, the powder and substance quantitative delivery device described in Patent Document 1 is composed of an upper container 1 and a lower container 3 to which a required powder is supplied, The upper container 1 and the lower container 3 are partitioned by a medium interval plate 2, and an appropriate number of pressure adjusting ports 4 are provided in the intermediate interval plate 2. The bottom of the lower container 3 is composed of a fixed ring body 5 forming a peripheral wall and a horizontal base 6 forming the bottom surface thereof, and a part of the fixed ring body 5 is cut out so as to communicate with the upper part of the discharge cylinder 7. Part 8 is formed.

  A vertical rotating shaft 10 reaching the upper container 1 is provided at the center of the machine base 9 that supports each of the fixed portions. The stirring blade 11 that rotates in the upper container 1 and the lower container 3 The agitator 12 and the rotating disk 13 that are rotated by the above are fixed. A flange bottom portion 13a is integrally provided in the turntable 13 in the vicinity of the horizontal base 6 so that an annular passage 14 forming an annular space by the turntable 13, the flange bottom portion 13a and the fixed ring body 5 is formed. It is formed.

  Further, an appropriate number of fixed blade pieces 15 project horizontally from the upper portion of the fixed ring body 5, and the fixed blade pieces 15 are stirred by a relative action with the stirring body 12 and the annular passage 14. Gives a smoothing action to the powder particles filled inside. Further, a partition plate 16 is horizontally provided above the cut portion 8 of the fixed ring body 5 so as to cover a part of the annular passage 14, and the granular material is externally attached to the fixed ring body 5 through the cut portion 8. A gate 17 is provided which leads to Then, a scraper 18 that scrapes powder particles is provided on the rotating disk 13 with respect to the lower surface of the partition plate 16 and the fixed ring body 5 of the annular passage 14.

  Therefore, the powder and powder quantitative delivery device configured in this way supplies powder and powder for quantitative discharge to the upper container 1, and the stirring blade 11 is moved in the upper container 1 by the rotary shaft 10. When the stirring body 12 and the rotating disk 13 are simultaneously rotated in the lower container 3, the powder particles in the upper container 1 continuously pass through the pressure adjusting port 4 and enter the lower container 3 at a constant pressure. It is sent down. In the lower container 3, the annular passage 14 is continuously filled while being uniformly dispersed by the appropriate number of fixed blade pieces 15 and the stirring body 12 fixed to the upper part of the fixed ring body 5. Accordingly, the granular material in the annular passage 14 rotates at a substantially constant speed on the flange bottom portion 13a of the rotating turntable 13, and from the cut portion 8 of the fixed ring body 5 to the outside along the outer surface of the gate 17. In this way, a continuous quantitative discharge of a desired amount can be precisely performed.

  Conventionally, table feeders and disk feeders having various configurations have been proposed as powder body supply apparatuses that continuously and quantitatively supply powder bodies using a rotary table or disk.

  For example, it is possible to reliably prevent the growth of powder from adhering to the storage tank wall without using a stirring blade, and to ensure good quantitative performance and to easily perform inspection and maintenance of the quantitative introduction and discharge means. A configured table feeder has been proposed (see Patent Document 2).

In other words, the table feeder configured in this way can reliably prevent the growth of powder adhesion to the storage tank wall without using a stirring blade, and excellent quantitative performance is ensured. Has the effect that the inspection and maintenance of the quantitative introduction and discharge means can be easily performed.

  In addition, the supplied granular material descends uniformly without rotating around the central part, is discharged with a repose angle formed in the circular powder passage, is discharged at a constant speed without being affected by the powder pressure, In addition, there has been proposed a disk feeder configured to perform first-in first-out of the supplied granular material (see Patent Document 3).

Not only can the powder that has advanced into the passage without being affected by the load (powder pressure) in the inner cylinder be supplied continuously to the next process at a constant speed by the rotary table, but also first-in first-out in the inner cylinder. It is performed, and there is an effect that quantitative supply is performed without stagnation.

  Furthermore, a disk feeder for a granular material has been proposed as a quantitative feeder that can stably discharge even a powder or powder that contains sticky powder or a large lump or easily slips ( (See Patent Document 4).

The granular material disk feeder described in Patent Document 4 is provided with a base on the machine frame, an upright rotation shaft at the center of the base, and a horizontal rotary table at the upper end of the rotation shaft, An upright cylinder is erected on the outer periphery of the platform, the outer periphery of a donut-shaped horizontal disk is connected to the upper end of the upright cylinder, an inner cylinder is provided on the inner periphery of the horizontal disk, and the lower end of the inner cylinder and the rotary table A material discharge interval is provided between the upper surface of the cylinder, an outer cylinder is provided inside the upright cylinder, and a lower end of the outer cylinder is slidably contacted with the upper surface of the rotary table to form a powder passage between the inner and outer cylinders. In addition, a guide scraper that is in sliding contact with the upper surface of the rotary table and that has both end portions fixed to the inner surface of the inner cylinder is provided, a discharge port that faces the passage is provided, and a discharge scraper is provided in the passage. .
