Abstract

The invention relates to the field of mechanical engineering and can be used for the briquetting of grass meal, peat and other dispersed materials. The purpose of the invention is to improve the quality of briquettes by increasing their strength. The briquette press contains a loading chamber 1, a punch 2, an ejector 3, a die 4, consisting of a sleeve 5 with capillary slit-like channels 6, a band 7 and a band 8 with a drive. The matrix is installed in the brackets 9, mounted on the frame 10. The sleeve is rigidly connected to the tires 7 and 8. The drive can be performed, for example, toothed, chain, etc. It provides rotational movement of the matrix relative to the axis of the punch. The loading chamber 1 is mounted on the bracket 9, coaxially with the matrix and has an opening 11 equal to the internal diameter of the matrix in which the punch is installed, and an opening for unloading 12. The punch and ejector are connected to a drive providing a reciprocating motion. The working surfaces of the punch and ejector are curved, for example, sinusoidal, the punch and ejector are set opposite each other so that their working surfaces are equidistant. Capillary slit-like channels 6, located tangentially to its inner surface, are made in the sleeve of the matrix 4. 2 Il.

Description

The invention relates to mechanical engineering and can be used in the briquetting of grass meal, peat and other dispersed materials.

The aim of the invention is to improve the quality of briquettes by increasing their strength.

FIG. 1 shows a press, cross section; in fig. 2 shows section A-A in FIG. one.

The briquette press contains a loading chamber 1, a punch 2, an ejector 3, a die 4 consisting of a sleeve 5 with capillary slit channels 6, a band 7 and a bandage

8c driven. The matrix 4 is installed in the brackets 9 mounted on the frame 10. The sleeve 5 is rigidly connected to the band 7 and the band 8. The drive can be performed, for example, toothed, chain or other, providing rotational movement of the matrix 4 relative to the axis of the punch. Boot chamber mounted on bracket

9 is coaxial to the die 4 and has an opening 11 equal to the inner diameter of the die in which the punch 2 is installed and the opening 12 for unloading. The punch 2 and the ejector 3 are connected to a drive that provides reciprocating motion. The working surface of the punch 2 and the ejector 3 is made of a curved shape, and the punch 2 and the ejector 3 are set against each other so that their working surfaces are equidistant.

With the exit direction of the capillary slit-like channels 6 from the matrix 4. As the punch moves as the compressible material compresses, the gaseous phase is squeezed through the channels 6. In the final pressing phase, the liquid phase of the compressible material is partially squeezed through the capillary channels. After pressing is completed, the drive of the punch 2 is turned off and the drive of the ejector 3 is turned on, which moves the briquette and the punch

2 to 12 openings for unloading, the length of which is significantly longer than the maximum height of the briquette. Ejector

3 is returned to its original position. The briquette released by the ejector 3 drops out through the opening 12 for unloading. The punch 2 is set by the actuator to its original position and the process is repeated. The control of the drive of the punch, ejector, dies can be carried out using limit switches or any other devices providing a predetermined position to the punch and ejector.

The economic effect of the invention is provided by increasing the quality of the briquettes.

Claims (1)

Invention Formula A briquette press containing a loading chamber connected to the die, a gas outlet unit of the latter, a punch and an ejector, tangential to its internal 40, characterized in that, in order to improve the quality of the briquettes, the gas discharge unit is made in the form of capillary slit-like channels located tangentially to the internal surface of the matrix, the latter is mounted for rotation about the axis of the punch in a direction coinciding with the direction of exit of the capillary slit-like channels from the matrix, while the punch and ejector are placed coaxially with the matrix. 45 surface. Briquetting press works as follows. The extruded material is fed into the loading chamber 1, from where it spills into the matrix 4. The drive of the punch 2 and the matrix 4 is turned off. The punch moves towards the ejector 3, which is fixed at this time, and the matrix rotates in the direction coinciding with J- / I FIG. 2
