Description

[Detailed description of the invention] This invention relates to a stirring device used when mixing two or more kinds of substances.

In recent years, moist pellet baits have been increasingly used in fish farms. This moist pellet feed is made by pulverizing frozen feed of raw foods such as small fish using a pulverizer, then mixing the pulverized product with mixed feed, stirring, kneading, and granulating it using a granulator. It is something.

In the production of moist pellet feed as described above, conventionally a ribbon mixer was used to mix the crushed material and mixed feed, but it took a very long time to mix and the crushing function was extremely low, making it difficult to get a good mixture. Moreover, the long mixing action increases the temperature of the feed and reduces its freshness.

Therefore, this invention solves the above-mentioned drawbacks and provides a stirring device that can efficiently mix, stir, and knead two or more kinds of substances, such as pulverized materials and mixed feed, in a short time. The purpose is to

To achieve this objective, this invention provides a pair of parallel horizontal shafts that are driven to rotate in opposite directions inside a stirring barrel that has a discharge port that can be opened and closed at the bottom. The shaft is arc-shaped, and each of the horizontal shafts has a number of stirring plates having a plurality of radially arranged blades installed at an angle. The mounting device of the horizontal shaft is regulated so that the rotation locus of the tip of the blade due to the stirring plate partially overlaps with each other, and the horizontal shaft is tilted in the opposite direction. A pair of horizontal shafts that rotate are rotated forward and backward alternately, and each stirring blade moves the raw material introduced into the stirring barrel in the axial direction of the horizontal shaft and around the horizontal shaft. In addition, the stirring blade is used to crush the raw material.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The drawing shows an apparatus for producing moist pellet bait. This manufacturing device includes a crushing device 1 for frozen bait,
Stirring device 10 and granulation molding device 30 according to this invention
It consists of a combination of.

The above-mentioned crushing device 1 has two rotating shafts 3, 3 attached inside a casing 2, and each rotating shaft 3 is provided with a large number of plate-shaped rotating blades 4 in a comb-teeth shape. Rotating axis 3
Each of the
It is rotated in the direction of the arrow in the figure. A large number of fixed blades 5 are attached below the pair of rotating shafts 3 in a comb-teeth shape. Reference numeral 6 shown in FIG. 2 indicates a support plate for the fixed blade 5.

Now, when the frozen bait is put into the interior through the upper opening of the casing 2 and the pair of rotating shafts 3 are rotated in the direction of the arrow in FIG. 4, and further crushed by the rotary blade 4 and fixed blade 5. This pulverized material is supplied to the stirring device 10 from the lower end outlet of the casing 2.

The stirring device 10 includes a stirring barrel 11, and the upper part of the stirring barrel 11 is provided with a supply port 12 that communicates with the lower end outlet of the casing 2, and a pair of horizontal shafts 13, 13 are arranged in parallel inside the stirring device 10. It is installed. The bottom of the stirring barrel 11 is formed in an arc shape centered on each horizontal axis 13, and a discharge port 14 is provided at the center of the portion where the pair of arc-shaped bottom surfaces intersect.
An opening/closing bottom cover 15 is slidably supported along a rail 16 attached to the lower surface of the bottom plate of the stirring barrel 11.

A support piece 17 is attached to the lower surface of the bottom cover 15, and a threaded rod 1 is screwed into this support piece 17.
8 is axially immovably but rotatably supported, and the threaded rod 18 and the handle shaft 19 crossing this are interlocked via a bevel gear 20, and the handle shaft 19 is attached to the end of the handle. When rotated by the operation 21, the bottom cover 15 slides to open and close the discharge port 14.

The horizontal shaft 13 is a forward/reverse motor 22 shown in FIG.
The shafts are rotated in opposite directions. A large number of stirring plates 23 are attached to each horizontal shaft 13 in an inclined manner, and each of the stirring plates 23
A plurality of blades 24 are provided radially. As shown in FIG. 3, the stirring plates 23 of each horizontal shaft 13 are inclined in opposite directions with respect to the central part in the longitudinal direction of the horizontal shaft 13 as a boundary, and the stirring plates 23 of the other horizontal shaft 13
It is symmetrical with respect to

When the pulverized material is introduced into the stirring barrel 11 from the pulverizer 1 and the pair of horizontal shafts 13 are rotated in opposite directions, the pulverized material is transferred to one of the horizontal shafts 13 by the rotation of the tilted stirring plate 23. Around the other horizontal axis 13, it moves toward the center of the stirring barrel 11, and around the other horizontal axis 13, it moves toward both ends of the stirring barrel 11.

Due to the counter-flowing macroscopic flows of the crushed material, the crushed material mixes with the other at the boundary between the two flows, while the rotation of the stirring plate 23 causes the crushed material to be cut and crushed by the blades 24 on the periphery of the stirring plate 23, and the crushed material is also cut and crushed by the blades 24 on the periphery of the stirring plate 23.
During this time, the ground material moves from top to bottom or bottom to top, and mixing is performed by the intersection of micro-flows such as stirring of the descending ground material and the ascending ground material.

The pair of horizontal shafts 13 are repeatedly rotated forward and reverse at regular intervals, and as a result, the pulverized material is mixed very effectively and in a short time, and the mixture is then supplied to the granulator 30. be done.

The granulating device 30 is provided with a screw 33 inside a cylindrical casing 32 having a supply port 31 at the top, and the screw 33 is connected to a motor 3 shown in FIG.
4 to rotate in one direction.
Therefore, when a mixture is supplied to the inside of this cylindrical casing 32 and the screw 33 is rotated, the mixture is moved by the screw 33 toward the tip of the casing 32, and the mixture is transferred to the die 35 provided at the tip of the casing 32. pushed out of the hole.

In this device, a stirring plate with a plurality of radially arranged blades is installed at an angle on a pair of horizontal shafts provided inside the stirring barrel, and the stirring plates on each horizontal shaft are reversed with the center of the horizontal shaft as the border. It is characterized by having a tilted direction and a symmetrical shape with respect to the stirring plate of the other horizontal axis, and when the mixture is supplied into the stirring barrel and the pair of horizontal shafts are rotated in opposite directions, A flow of the mixed materials toward the center of the stirring barrel and a flow of the mixed materials toward both ends are generated, and the mixed materials are crushed by the blades on the outer periphery of the stirring plate, and further, the mixed materials are crushed between adjacent stirring plates. Because of the upward and downward movement, the materials to be mixed can be effectively mixed, stirred, and kneaded in a very short time.
