Description

(54) CONSTRUCTING FOR CRUSHING OF RUBBER-TEMPLATED MATERIALS and other waste. The present invention may be used in the chemical food, wood processing industry, in agriculture for the grinding of cereals. The device is known to grind various materials. 1. The device contains Kojpnyc, a booker fixed on it, a working body made in the form of a carriage with knives, working reciprocatingly. The carriage is made with transverse slits for the knives, and is also equipped with a hinge-hanging plate and scrapers with their turn restrictions. The hopper is adapted to move in a direction perpendicular to the movement of the carriage, by means of an individual drive. A disadvantage of this device is that it does not allow fine grinding of the rubber-fabric material. Rotating knives in carriage-. They cannot give the necessary crumbs and its standard. The closest of the known technical essence and the achieved effect is a device for grinding rubber-fabric materials, comprising a housing with a hopper and a mouth for loading, a working body located under the bunker in the housing, including a punched table and a cutting unit 2 interacting with its lower surface. In the known device, the hopper is rigidly fixed on the table. The disadvantage of this design is the high vibration of the entire device, which makes it difficult to maintain. The need to increase the area of the perforated table due to the achievement of high performance leads to a significant increase in overall installation size and noise, which reduces the effectiveness of the known device. The purpose of the invention is to increase the efficiency of the device.

This goal is achieved by the fact that a device for grinding rubber-fabric materials, comprising a housing with a hopper and loading neck, an operating member comprising a perforated table and a cutting unit interacting with its lower surface, located under the bunker in the housing, is provided with a ramming tool located above the table type, while the table is rigidly fixed in the housing, and the cutting unit is made in the form of a floating disk with knives, rotatable from the drive.

In this case, the knives of the disk are located at an angle of 20 to the plane of the cut. In addition, the disk is spring-loaded to the table.

Figure 1 shows a General view of the device; FIG. 2 shows a disk with knives, a cut in the side of the spokes with a knife.

The device has a housing 1, a hopper 2 on which a drive (electric motor) 3 is mounted, a receiving neck 4. The drive is connected by means of a coupling 5 to an axis 6 of the device. The perforated table 7 with a hole for the bearing of the axis 6 is aligned with the housing 1. On the axis 6, there is mounted a sleeve with a V-belt pulley 8 and a rotator 9. Piston type, driven by the V-belt transmission 10 from the motor 11. Under the perforated table 7 on a sliding hinge fit the spring 12 is pressed against the lower surface of the table 7 by the foot disc 13, which can move in a vertical plane. Disk knives are located at an angle of 20 to the plane of the cut.

The housing 1 is equipped with a second grinding stage, which consists of a perforated table 14 having an opening for an axle bearing 6, on which is mounted a sleeve with a V-belt pulley 15 and a plunger-type agitator 16, driven by a V-belt transmission 17 from the motor 18.

Under the table 14 on the sliding articulated landing, the spring 19 is pressed against the lower surface of the table 14 knife disc 20, which can move in a vertical plane. Under the second stage on the housing 1, the receiving bunker 21 is strengthened.

The device for grinding "rubber fabric materials works as follows.

The coarse graded component, HanpilMep vulcanized rubber, after grinding in a crushing belt conveyor (not shown), is poured into the hopper 2 through the receiving neck 4 and enters the opening of the table 7. To remove the hang, the coarse crumb on the table 7 slowly rotates and moves crumb agitator 9 plunger type.

The crumb rubber crumb, entering the apertures of the table 7, at the exit of them is cut by the blade discs 13, rotated at high speed, about 3000 rpm. The cut crumb enters the second stage of grinding, where it is also over one hundred. scrap 14 mounted plunger type agitator 16, eliminating sticking, sticking of crumbs. The crumb passage through the holes of the table 14 is cut by a blade disc 20, rotating at the same speed as the blade disc 13.

Finely crushed crumb after the second stage of crushing enters the receiving bin 21, from where it is sent to the consumer,.

The described device is a high-performance continuous device.

 The device allows you to get Kpotyxy of the required size with the same amount of grinding, because The cut is carried out with a whole circular knife at a high speed, approximately 3000 rpm at constant power, through holes of a certain size.
