JPS63134045A - Granulator - Google Patents

Abstract

PURPOSE:To enhance the durability and working efficiency of the title granulator by providing a discoid die having many small through holes, horizontally provided on the underside of the granulator and a roller pressing the surface of the die, rotating, and revolving with the center of the die as the axis. CONSTITUTION:The driving members are excluded from the inside of the granulator 4 to the outmost, hence the rotating and revolving of the roller 2 being brought into contact with the materials 9 and 9' are not disturbed, and the granulator functions smoothly. the powdery material 9 sent in from the pretreating stage 8 wherein crushing, heating, warming, etc., are carried out is charged into a granulation chamber 4 from a charging port 31 at the top of a casing 3, compressed by the upper die 1 and roller 2, and then charged into small holes 13. The material 9' extruded from the small holes 13 is cut by the cutter 6 fixed to a forming shaft 5 to an appropriate length in the form of pellets, and the pellets are dropped onto a discharge plate 32 at the bottom of the casing 3 and discharged from a discharge port 33.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an apparatus for granulating and forming a material into a pellet shape. More specifically, the present invention relates to an improvement in a low moisture type (dry type) granulation device that utilizes high pressure.

[Prior Art] Conventionally, as a low moisture type granulation device, for example, the one shown in FIG. 3 is known.

This conventional granulation device consists of a cylindrical die A having a large number of small holes A'' passing through from an inner circumferential surface A' to an outer circumferential surface A'', and a die that rotates on its own axis while being in pressure contact with the inner circumferential surface A' of the die. and a roller B that revolves around the central axis of the die A. In this conventional granulation device, roller B as shown by the arrow
Due to the rotation and revolution of has been done.

Problems to be Solved by the Invention In the conventional granulation device described above, the die 8 has a structure in which a small hole A is formed in a cylindrical shape, so it is troublesome to drill the small hole A''. There was a problem of increased manufacturing cost, and there were also problems with durability, such as die A being deformed by the pressure of roller B.Furthermore, if small hole A/// became clogged, The removal work had to be carried out along the circumferential surface of the cylindrical shape, which caused problems in terms of efficiency in use.

The present invention was made to solve these problems, and its purpose is to simplify the structure around the dice.

[Means for Solving the Problems] The granulation device according to the present invention includes a disk-shaped die having a large number of small holes penetrating from the front surface to the back surface and installed horizontally inside the granulation chamber; We are looking for a means that is equipped with a roller that rotates on its own axis while pressing against the surface of the die and revolves around the center of the die.

[Function] The granulation device according to the present invention has a simple structure in which the die is flat and the roller rotates and revolves on its surface, thereby solving the above-mentioned problems in manufacturing, durability, and usage efficiency. It is something to be solved.

[Example] Hereinafter, an example of the granulation apparatus according to the present invention will be described based on FIGS. 1 and 2.

FIG. 1 shows the main parts of an embodiment of the granulation device according to the present invention. In this embodiment, the die l is disc-shaped, and the surface Il of the die I is shown as an arrow. roller 2
is designed to rotate and revolve. The die 1 is provided with a large number of small holes 13 penetrating from the front surface 11 to the back surface I2, but the drilling range of the small holes 13 depends on the rotation of the roller 2
It is sufficient within the region of revolution. In addition, the drilling work of small hole 13 is as follows:
Since this is carried out on the flat die 1, it can be done precisely and easily by using a drill machine or the like.

Furthermore, if the thickness, material, etc. of the die 1 are modified, it is easy to increase the durability, and deformation etc. can be completely prevented and a high degree of durability can be obtained. Note that the number of rollers 2 is arbitrary, but if a large number are provided, it is preferable to arrange them radially from the center of the die 1 in consideration of the balance of revolution.

FIG. 2 shows the structure of the main parts shown in FIG.
It is fixed to the casing 3 and installed at the lower part of the granulation chamber 4 surrounded by. Rotates on the surface ll of die 1,
The rotating rollers 2 are supported by a vertical shaft 5 that protrudes from below through the center of the die 1, and the rotation of the vertical shaft 5 causes the rollers 2 to revolve around the center of the die 1, and Due to this revolution, the roller 2 rotates on its own axis in relation to the die 1. The vertical shaft 5 is connected at the bottom and is connected to the motor 10 via a speed change mechanism 7.

The structure shown in FIG. 2 eliminates drive system members as much as possible from inside the granulation chamber 4, so there are no factors that hinder the rotation and revolution of the roller 2 that comes into contact with the material 9, 9', etc. Without,
It has the advantage of functioning smoothly.

In the embodiment shown in FIGS. 1 and 2, the powdered material 9 fed from the pretreatment process 8 such as crushing, heating, and humidification is introduced into the granulation chamber 4 from the input port 31 at the top of the casing 3. Enter,
The small hole 13 is compressed by the upper die 1 and the roller 2.
will be injected into. The material 9' pushed out from the small hole 13 is cut into appropriate lengths by a cutter 6 attached to the vertical shaft 5, becomes a pellet, falls onto the discharge plate 32 at the bottom of the casing 3, and flows into the discharge port 33. leak. Under such conditions of use, material 9.9' is inserted into the small hole 13.
If the die 1 becomes clogged, for example, the casing 3 can be disassembled to expose the die 1, thereby easily removing the clog.

[Effects of the Invention] As described above, the granulation device according to the present invention has the effect of reducing manufacturing costs and improving durability and usage efficiency by simplifying the structure around the die.
