Description

Detailed Description of the Invention

[0001]

[Industrial application] Foods (vegetables, rice, wheat, beans, seaweed, fish and shellfish, dried meat, etc.) and its by-products (rice husks, fruit peels,
Sesame meal, okara, seafood waste, etc.) Chemicals, ceramics, mining, chemicals, building materials, etc.) and the recycling of these by-products or waste materials into powder is becoming more and more important in our daily lives. It is coming. In Japan, where resources are scarce, resource reuse is currently an indispensable element. However, many substances are relatively difficult to generate powder, and even if powdering is possible, the cost is high. In the process of pulverization, there is no merit in pollution problems such as noise and dust or transportation cost, and it is a method of burying it underground or dumping it at the sea, which also causes secondary pollution. In order to solve various problems, the present invention is considered to expand the field of industrial application.

[0002]

2. Description of the Related Art There have been many methods used for powdering, and there are many models from crushers to jet mills from coarse crushing to fine crushing. The methods are from compression, shearing to grinding. There are some that are chemically pulverized, but depending on the raw material, many substances are difficult to pulverize.For example, in foods, konjac materials are pulverized, rice husks are pulverized, and sesame meal containing oiliness, soybeans are pulverized. It is very difficult to do so, and the technology for producing powder such as waste materials of plastics and construction materials by mineral resources and chemicals has not been reached enough, and the development of new technology has been awaited.

[0003]

Although there are cases in which these conventional techniques can be improved by improving them, the equipment cost is high, and there are many parts which are considered to be insufficient by the conventional method. For example, Sufficient deoiling, dehydration in the previous step, difficulty in pulverizing substances containing fibrous materials with many conventional crushers, abrasion of crushed parts, electricity cost etc. The present invention, which has not been obtained, significantly reduces and improves the above-mentioned drawbacks.

[0004]

[Means for Solving the Problems] The stone or wooden mortar used for a long time, and how the grinding mill was useful in human life, from the basics of creating powder particles naturally Focusing on the superiority of dies such as compression, shearing, impact, twisting, grinding, bending, and gloss, activation, which is an idea,
The present invention is intended to obtain a powder of good quality in a relatively simple manner and in a large amount from powder particles which are difficult to be crushed by a conventional crushing machine. Drawing 1 As shown in the front sectional view,
The drive spindle (2) and the outer wall body (3), which have an appropriate rotation transmitted by the electric motor, have a concavo-convex mortar-shaped tapered cone type mortar (4) (5) in which twisted tooth-shaped grooves are formed on the surface in multiple rows. ) Are connected in series, and the discharge port side is placed on the opposite side, and the two convex rotary rotors (6) and (7) fixed coaxially are pressed and rotated to make the pulverized material overflow. The powder is crushed and then ground and crushed to form powder by centrifugal force and discharged.

[0005]

[Function] The raw material, which has been supplied in a fixed amount, is bitten into the raw material supply side of the double mortar-shaped tapered cone type mortars from the direction of the taper cone diameter, and press-contacts, crushes, and grinds the press-contacting spaces of the mortar according to the excess flow Repeatingly, the powder and granules progress in the small diameter direction and are finely crushed, and the passed granular material is further crushed from the small diameter direction of the reverse hand mill in the small diameter direction and crushed by the centrifugal force while rotating. Scatter and continuously obtain finely divided particles. FIG. 5 illustrates this state.

[0006]

EXAMPLES The present invention will be described in accordance with examples.
As shown in FIGS. 1, 2, 3, and 4, the power generated by the reduction motor (1) mounted on the machine base (8) is transmitted from the chain sprocket (9) to the connecting chain (10).
Is transmitted to the chain sprocket (11) via the shaft, and the main shaft (2) is driven, and two rotary taper cone rotors (6) having a multiplicity of twisted tooth-shaped groove blades on the surface fixed coaxially. (7) is rotated by the transmitted horsepower,
It has a structure corresponding to the mortar (4) (5) having a plurality of opposing spiral tooth-shaped groove blades, both of which are fixed to the outer wall body (3). The raw material supply side mortar (4) (6) and the lower discharge side mortar (7) (5) are fixed reversely, and the powder is discharged to the lower part as shown by the arrow at the discharge port (12) by the scraping plate (13). FIG. 3 shows a structure in which fine powder is automatically discharged to the outside through the external discharge port (12) in accordance with the rotation of the main shaft (2), which is a vertical type in FIG. FIG. 4 is a view of the spiral tooth-shaped groove taper cone mortar (4) on the raw material supply side and the rotary taper cone rotor (6) paired with each other as seen from above. 5) and the pair of rotating taper cone rotors (7) are seen from the bottom, therefore they are fixed coaxially, and because they are on the same rotation, the twisting directions of the groove shapes are opposite grooves, respectively, and the spindle. (2) is received by the lower bearing (14) and the upper bearing (15) at two points. The rotation taper cone rotor (6) on the raw material supply side is tightened by the tightening taper (19) at the upper part. The gap between them is adjusted, the raw material supply port (16) is charged from the direction shown by the arrow, and the upper rotating taper cone rotor (6)
On the upper side, a conical raw material supply metal fitting (17) for evenly distributing the supplied raw material and a stirring guide plate (18)
The dotted line of the tooth profile shown in the front sectional view of FIG. 1 indicates the depth of the tooth profile groove. Although the embodiment is made of a rigid type, the same effect can be achieved by a horizontal type.

[0007]

By the practice of the present invention, it is possible to pulverize any raw material in general, but it has been considered very difficult to extract foods containing fibers, light vegetables and rice husks. Such as hard (silica) containing, oily (almost impossible with conventional crushing machine) plastics, glass fibers, etc., which enabled a wide range of crushing to mining chemicals, also a rotating rotor Since it can be operated at a low rotation speed, it also has the advantages of preventing heat generation, few wear products, and no need for dust collectors, etc., and has the advantage of being able to manufacture the machine at low cost, easy to handle, and two mortars. It has the advantage that it can be crushed by compression and dispersed and crushed by grinding and centrifugal force, and the power cost is low and the economic effect is large.
