Abstract

PURPOSE:To improve the operability of a titled device and to reduce the size of the device without decreasing the dispersion efficiency of a material to be treated by arranging 3 pieces of main rolls and auxiliary rolls provided in a rotary vessel of a cylindrical shape so as to rotate around the revolving shaft of the vessel. CONSTITUTION:The inside surface of a vessel 1 is formed to a cylindrical shape, and a revolving shaft 2 for driving is provided at the symmetrical axial center of the cylindrical shape. >=3 pieces of main rolls 6 in the same direction as the direction of the shaft 2 are disposed between the shaft 2 and the inside surface of the vessel, and both end prts of the rolls 6 are supported on the supporting members 7, 8 attached to the shaft 2, freely rotatably, and freely movably from the positions in contact with the inside surface of the vessel further to the inner side. Each piece of auxiliary roll 10 is held between the adjacent two rolls 6, and the rolls 10 are so disposed that the positions on the outermost sides are limited by the two rolls 6. In other words, the dispersion of the material to be treated is controlled only by controlling the number of revolutions of the shaft 2; therefore, the device is easy to operate.

Description

[Detailed Description of the Invention] * (Hereinafter referred to as "Nlupace" - IIXh) Regarding a rounding O dispersion device that makes a colloid A typical example is the roll mill. A roll mill performs molecular & by passing a roll base T-4 between driven rotating rolls that are placed one after the other, but this method has the following drawbacks: .

(1) By fixing multiple rolls in parallel, the 6-row nine-piece O-arashi model becomes large.

(2) For rounding to control dispersion, the gap between each roll must be cleared of mold, which is a rather troublesome task.

(3) If the q-ru threshold changes during operation, it will be a fault, and in that case, the predetermined dispersion will not be performed.

An object of the present invention is to provide a class IIr type dispersion apparatus which does not have the disadvantages of the conventional dispersion apparatuses as described above and has significantly improved operability. The purpose of the present invention is to provide a container with a cylindrical shape, a rotary rotation axis being provided in the container at the center of symmetry of the cylinder, and a threshold between the rotation axis and the inner surface of the container having a ra. Three or more main rolls are arranged in the same direction as the rotation axis, and the main rolls are attached to the rotation axis and are rotatable to the support member and can be moved further inward from the position in contact with the inside of the container. One subordinate roll is held between two adjacent main rolls, and the outermost position of the subordinate rolls is limited by the two main rolls. It is constructed by a dispersion device having certain characteristics.

Hereinafter, the present invention will be explained in detail based on FIG. i1.

FIG. 1 is a vertical cross-sectional view of the 1111 device of the present invention (however, some parts are not shown as will be described later).

The inner surface of the container 1 of the present device is cylindrical.

In the case of the figure, 8zaki is #IJIiI, but it is not necessarily vertical.
There is no need to make it wrinkled, and horizontal wrinkles may appear. The ratio of the inner diameter to the length of vllll is, for example, 1/4 degrees. There is a rotating shaft inside container 1! is provided, and this rotation axis 2Fi is rotatable around the axis of symmetry of the wO circle shape inside the container 1. Axis of rotation!
For example, 1/341 degree of the inner diameter of the case III is 6
The rotating shaft 2 is driven by a driver R8 (variable speed motor). L+ and 5 are bearings (bearings) for the rotating shaft 2. These bearings 4 and 6 are attached to the cylindrical shape of the container 1.

Three or more main rolls 6, preferably five main rolls 6, are arranged in the container 10 in the same direction as the rotating shaft 2. The length of the main roll is nine, which is the same as, for example, 20 rotating wheels. This main roll 6 is supported at both ends thereof by a support member 7 and a spout. Support members 7 and 8 are attached to both ends of the interior portion of the rotating shaft 2. This number of support holes S is provided, and the support hole portions 9 are substantially arranged on the same circumference.
The base rolls, which are preferably arranged in the K-position, are supported in the support holes 11 of the two support members 7 and - so as to be freely rotatable. For example, the support hole may be formed in the radial direction (i.e., in the rotation direction 2).
By forming the main roll 6 into an elongated shape in a direction perpendicular to the rotational circumferential direction of the main roll 6, Make sure that it is possible to change the direction inside the container.

-Kj? Although the main roll 6#i is directly connected to the support hole 9, a subordinate roll 1o is provided between the main roll and the main roll so that the main roll rotates smoothly 60 times. The slave roll 1o has a smaller diameter than the king roll 6 (preferably Fi3/lo lengthwise) and is located more inward than the main roll. That lk! I11 is as shown in Fig. 3 (this Fig. 3 is based on the cross-sectional view of line 2 in Fig. movement in the p-rotation circumferential direction is prevented by the housing*, the rotating shaft 2, and the main roll 6.

There are two supporting rolls 7 and 80 as shown in the figure.
Although it may be freely positioned in the center, it may be supported by the support members 1 and 8 in the same manner as the king roll 6 described above. In this case, when the main roll 6 is located at the outermost position (that is, when it is in contact with the inner surface of the container 1), the subordinate roll 10 is connected to the two main rolls.
Make sure that you can access it from the inside.

In this way, the relationship between the rotating shaft 2 and the two fI4 shift main rolls 6 is always maintained regardless of the rotating shaft 2 (one secondary μm roll 1
It can be positioned at 0.

It is preferable that the container 1 of the apparatus of the present invention is interleaved as shown in the figure, and it is possible to provide a milbeme inlet 11 and a milbase outlet 121 at both ends thereof. In addition, in order to prevent the equipment from overheating due to the heat generated during j1 transfer,
and - cooling water passages 13 and 14 can be provided during wheel rolling. 15 and 16 are the inlet and outlet of the cooling water to the volume Ill, respectively.

1 to Ilbase [Driving and rotating the rotating shaft 2 while feeding. As a result, the main roll 6 attached to the mounting member 7 and the main roll 6 is rotated in rotation 2, and the resulting centering force forces the main roll 6 against the inner surface of the container 61, causing its rotation. The main roll 6 rotates based on the movement. As the main roll 6 rotates around the rotation axis, the slave roll 1o
The rotation is controlled for 4 hours, and the resulting concentric force forces the slave roll 10 against the two main rolls, and at the end of the day, the slave roll 10 rotates on its own axis based on its friction. The direction of rotation of the slave roll 10 is opposite to the direction of rotation of the main roll 6.
Rotation and rotation axis! (includes a complete turn)
P is indicated by an arrow. In this way, due to the OKA rotation of the housing structure part 1, a pressing force acts on the threshold between the inside of the container 10 and the main roll 6 and between the main roll 6 and the slave roll 10 according to the rotation speed of the rotating shaft 20, and these The p-order IIK dispersion progresses as the O2K oil base passes through, and the desired dispersion finishing liquid is obtained.

The above-described device has the following advantages.

(1) a - le @ and 10 turns -2 igl*t
The device can be made unusable without reducing the dispersion efficiency due to the multi-rotation format.

(2) Dispersion control is based on rotation! Since this can be done only by controlling the number of oafEs, it is easy to repeat.

(3) Even if the dimensions of each component change due to temperature changes, wear, etc., there is little effect on dispersion.

(4) - Axis rotation! By rotating the IT roll 1 time), 1 base oil is applied, and the uniformity of the dispersion is reduced.

(5) When the volume is 111 tons, there is no volatile residue of solvent, etc., and therefore there is no change in the composition of the turbid liquid and no border pollution.
Furthermore, dispersion processing will continue to be implemented.
