Description

Upright Polymer Grinder {A High Molecule Material Pulverizer}

The present invention relates to an upright polymer material pulverizer, and more specifically, to be vertically erect from the ground, the polymer material to be injected is crushed downward and moved, thereby significantly reducing power consumption and improving the grinding speed. It relates to an upright polymer material mill.

In general, regeneration of thermoplastic polymers and elastomers is a field that has been studied for a long time in the environmental field, and thermoplastic polymers have been recycled by extruding them by crushing them into small pieces and melting them at high temperatures. Due to the bonding, it cannot melt and regenerate at high temperatures, so it goes through a desulfurization process that reduces its size. This desulfurization process is performed at room temperature or low temperature.

At this time, the desulfurization process at room temperature uses a method of reducing the size of the rubber scrap at room temperature in order to produce small particles of 0.5 to 1.5 mm diameter by grinding the wheel with grooves. It is easy to freeze at low temperature and grind it. In other words, the polymer material is crushed by a high deformation ratio.

However, in order to proceed with the desulfurization at a low temperature, an expensive low-temperature facility must be used, and methods for producing good rubber pulverized particles at room temperature are being researched and developed. Such a device for desulfurizing a conventional polymer material is as follows.

1 is a cross-sectional view showing a conventional grinder.

As shown in the drawing, the conventional grinder 100 has a cylindrical shape having an injection hole 111 for injecting a polymer material to be crushed on one side thereof, and an outlet 112 for discharging the pulverized polymer material on the other side thereof. Compression screw unit 120 having a cylindrical case 110, and a compression unit 121 made of a screw-shaped projection for rotating and receiving the rotational force of the motor and compressing and transporting the injected polymer material toward the discharge port 112 direction. And, it is combined with the compression screw unit 120 is composed of a grinding screw unit 130 is provided with a crushing unit 131 made of a screw-shaped projection on the outer periphery to pulverize and compress the compressed polymer material.

However, the conventional pulverizer pulverizes the polymer material with the pulverization unit provided in the pulverizing screw unit, but it is impossible to control the particle size of the pulverized polymer material. There was a problem in that a new mill suitable for the particle size to be produced.

In order to solve the above problems, the "polymeric material grinder" filed in 2006 by the present applicant and registered in 2007 registration number 0824583 is connected to the motor M and the motor M as shown in FIG. A first case having a crusher 140 installed and compressing, conveying, and crushing the injected polymer material and surrounding the crusher 140, and having a hopper H for supplying the polymer material; The second case 152 and the first case 151 and the second case 152 installed in close proximity to the first case 151 and the first case 151 are installed by the moving cylinder 160. The case 150 is guided along the outer surfaces of the first case 151 and the second case 152, and includes a case 150 including a moving crushing member 153 having an inclined surface 153a formed therein. To support the support member 170 and the motor (M) and the support member 170, Which consists of a receiving portion 180. The

At this time, the moving crushing member 153 is formed in a circular ring shape, the end is provided with a tube to guide the case. The movable crushing member 153 is connected to the lower portion of the moving cylinder 160, and moved back and forth by the driving of the moving cylinder 160, as shown in Figure 2 formed on the inclined surface (153a) on the inner surface Thus, the polymer material is crushed into particles of a desired size. That is, the movable crushing member 153 is driven by driving the movable cylinder 160 to adjust the distance between the inclined surface 153a of the movable crushing member 153 and the crushing unit 141 of the crushing device 140. If it is advanced, the space between the inclined surface 153a and the crushing unit 141 is widened, and the particles are greatly pulverized. If the particles are moved, the space is narrowed and the particles are pulverized. You can adjust the size.

However, since the polymer material pulverizer is installed in a horizontal form on the ground, the polymer material injected from the hopper must be crushed while moving in the horizontal direction, and thus there is a problem that the pulverization rate is lowered and excessive power is consumed.

In addition, there is a problem that a small number of particles of the polymer material crushed into the gap between the mobile crushing member and the second case is discharged.

The present invention is a shredding device for compressing, conveying and pulverizing a polymer material is rotated by a motor, the case consisting of a first shredding member and a second case and a moving shredding member moved by the moving cylinder is installed while wrapping the shredding device In the mill, the motor is provided with a flange portion on the outer surface, the transmission is integrally provided on the lower portion, the lower portion of the transmission is provided with a fixed portion, the flange portion and the fixed portion are interconnected by a plurality of supports, The first case has a coupling portion formed on the outer surface and bolted to the fixing portion, a plurality of fixing legs are provided on the bottom of the coupling portion so that the grinder is upright, and a connection portion is provided on the outer surface of the second case. Is connected to the bridge, the upper portion of the connecting portion is characterized in that the moving cylinder is supported, fixed.

In addition, the fixing portion is characterized in that the support portion further comprises a plurality of buffer seats and the support for supporting the hopper installed in the first case.

In addition, the second case and the mobile crushing member is characterized in that the interconnection via a connecting tube of bellows structure.

The polymer material pulverizer of the present invention is configured to stand vertically on the ground, and the polymer material to be injected is crushed downward and moved, thereby significantly reducing power consumption and improving the grinding speed.

In addition, by connecting the end of the mobile crushing member and the second case with a connecting tube, there is an effect that prevents the particles of the crushed polymer material to be discharged to the outside.
