Description

Agitating device to avoid sludge and foam of mold release solution

The present invention relates to a stirring device for preventing the formation of sludge and foam of the release solution.

In the refining process of the tire rubber, as shown in FIG. 1, the rubber material blended from the rubber compounding device (not shown) passes through the head 17 portion of the extruder 2, thereby sheeting or pelletizing. ) Process. At this time, the pellets or sheet pieces that passed through the extruder head 17 were kept in a high temperature state, so that defects such as sticking and damage to each other frequently occurred.

In order to solve such a problem, it is usually made to extrude, supplying a mold release solution to the extruder head 17 part (strictly pelletizer part). Specifically, as shown in FIG. 1, the release solution stored in the release solution reservoir 13 is supplied to the pelletizer of the extruder head 17 using the pump 11, and the solution thus supplied is The filter is filtered through a vibration screener 5 installed at the rear end of the extruder, and is then recovered to the release solution reservoir 13 via the solution recovery pipe 10.

However, when the release solution is recovered via the conventional vibration mesh 5, there is a problem that bubbles and sludge of the solution are generated. That is, the solution falling through the solution recovery tube 10 naturally bubbles not only because of the drop, but also because the main component of the release solution is an inorganic filler, there is a property that sludge is easily generated without flow.

Such foams and sludges fall out during the drying process of the rubber and become various harmful dusts, which are very harmful to the human body. In addition, the sludge component is contained in the rubber semi-finished product, which causes a defect.

The present invention has been made to solve the above problems, an object of the present invention is to suppress the generation of bubbles and sludge of the solution in the release solution reservoir, to provide a stirring device that can improve the working environment and improve the quality It is.

Means of the present invention for achieving the above object are as follows.

First, the stirring device for preventing the formation of sludge and foam of the release solution according to the present invention, the axis of rotation extending from the top of the release solution reservoir to the bottom, and is rotated by a motor; It is characterized in that it is composed of a propeller type stirring blade for removing bubbles and a propeller type stirring blade for removing sludge, which is continuously fixed from the upper side of the rotary shaft.

At this time, it is preferable that a lattice connecting net for removing bubbles is additionally installed on the rotating shaft between the defoaming blade for propeller type and the propeller type blade for removing sludge.

Moreover, it is preferable to configure the stirring device according to the present invention as an apparatus capable of automatic adjustment. That is, the flow meter for measuring the amount of the recovered solution flowing into the release solution reservoir; A controller for adjusting the rotational speed of the motor in accordance with the flow rate measured from the flow meter; It is desirable to additionally include a converter that converts the electrical signal from the controller into mechanical operation.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

2, the overall configuration of the stirring device for preventing the formation of sludge and foam of the release solution according to the present invention is shown.

The rotating shaft 30 driven by the motor 9 extends downward from the upper surface of the release solution reservoir 13. The rotation shaft 30 is preferably provided in a substantially vertical direction.

The propeller type stirring blade 20 for removing bubbles and the propeller type stirring blade 22 for removing sludge are successively fixed to the rotary shaft 30 from above. In addition, between the defoaming propeller type stirring blade 20 and the sludge removal propeller type stirring blade 22, a lattice type connecting net 21 for removing bubbles is additionally installed.

As shown in FIG. 3, the propeller type stirring blade 20 for removing bubbles is to remove bubbles contained in the solution flowing from the release solution recovery pipe 10, and similarly to the bicycle wheel 20-1. And the central shaft mounting portion is configured to be connected by the propeller 20-2.

The sludge removal propeller type stirring blade 22 is preferably made large enough so that sludge is not formed in the stored release solution, and the structure may be similar to that of the bubble removing propeller type stirring blade 20.

In addition, the lattice connecting net 21 for removing bubbles between the defoaming propeller type stirring blade 20 and the sludge removal propeller type stirring blade 22 is formed by itself from the release solution accumulated in the reservoir 13. It is a component for removing bubbles. In the present embodiment, the grid-shaped rod connecting structure is formed on the same plane, but may be formed of a grid-like structure formed on a curved surface. In addition, the structure may be connected by a rod, but may be formed into a lattice structure by forming a hole in a flat or curved plate. However, in order to effectively remove the internal and external bubbles, the lattice shape needs to be maintained.

On the other hand, the rotation of the rotary shaft 30 is preferably automatically adjusted according to the amount of the recovery solution flowing into the release solution reservoir (13). To this end, in the present invention, the flow controller 23 is installed in the release solution recovery pipe 10, and the controller 24 for proportionally adjusting the rotational speed of the motor 9 according to the flow rate measured from the flow meter 23. And a converter 25 for converting the electrical signal from the controller 24 into mechanical operation. That is, when there is much flow rate measured by the flowmeter 23, the automatic adjustment device which speeds up the speed of the rotating shaft 30, and slows it proportionally slow may be provided.

According to the present invention having the above-described configuration, by effectively suppressing the generation of bubbles and sludge in the reservoir of the release solution supplied to the extruder of the tire refining process, not only can the work environment be improved but also the quality can be improved. It can be effective in terms of safety and cost.
