Description

(54) BRIQUET PRESS CONPRESSOR

The invention relates to mechanical engineering and can be used for pre-compaction of feed mixtures - before they are fed into the bale chamber of a briquette press, mainly stamped.

A brim press sub-press is known, comprising a housing, with an outlet above the press bladder, housed in the casing, which feeds and seals the working bodies above the briquetting press bale chamber.

The disadvantage of such a press is that the sealing working body is made in the form of a spring-loaded piston, which carries out a pulsed flow only due to compression of the spring, which reduces the productivity of the device.

The purpose of the invention is to increase productivity.

This goal is achieved by the fact that the sub-press of a briquette press comprising a housing with an outlet above the press chamber of the press, housed in the housing, feeds and seals the working bodies, compacts the working body in the form of a drive screw, and a hollow drive gear.

a shaft with a screw groove, a screw shaft with a finger placed in the screw groove, while the screw shaft is mounted in a hollow drive shaft with the possibility of axial movement and is spring-loaded relative to this shaft.

Figure 1 shows the sub-press operator; in fig. 2 is a section aa in FIG. 1.,

The baler consists of feeding and sealing mechanisms. The feeding mechanism consists of two feeding working bodies 1 and 2, respectively, of the right and left directions, ending with blades 3 and synchronized by means of two cylindrical gears 4 fixed on the shafts of these screw working bodies. In turn, the shafts of the feeding screw working bodies rest on the ball bearings 5 mounted in the housing 6 of the sub-press having a feed neck 7. Using the flange 8 and the bearings 9, the feeding and sealing mechanisms are connected.

Claims (1)

The last variety of two sealing screws 10 and 11, respectively, of the right and left directions, the shafts of which are connected by special pillows 12 to the springs 13, which, in turn, are connected to the driveshafts 15 by means of similar pillows 14. Thanks to the telescopic coupling of the shafts drives 15 with shafts of screws 10 and 11, the latter have the possibility of axial movement. In the shafts of the sealing screws ILO and 11, the fingers 16 are pressed in, and the ability to move along the screw grooves 17, which are made in the shafts of the drives 15, in the opposite direction to the rotation of the latter. The shafts of the actuators 15 are mounted on tapered roller bearings 18, which are mounted in pipes 19 having loading windows 20 jHa with hubs of driving pulleys 21, there are belleville springs 22, {which perceive shock load of thrust nuts 23. The gap between the belted springs 22 and the thrust nuts 23, the initial amplitude of the damped oscillations of the compacting screws 10 is set. The sub-press driver is fastened to the stamp briquette press by means of flanges 24 and 25 in such a way that its outlet openings 26 are located above the stamps 27. The sealing mechanism of the sub-press driver is driven from two electric motors 28 by means of V-belt transmission through drive pulleys 21. The feed drive the subpress box mechanism is realized through the pulley 29 by means of a V-belt transmission. Podpressovschik works as follows. The compacted material is fed into the loading neck 7 of the horizontal mechanism and, with the help of feeding screw working bodies 1 and 2, is conveyed to the loading windows 20 of the sealing augers. The blades 3 feed the material into the uplifting screw working bodies and. The flattened material is evenly divided into two equal flows. When the stamp 27 of briquette presses is in the front position, i.e. One of the outlets 26 of the sub-press is closed, the sealing screw 10, sealing the material in the area of the outlet 26, is moved in the axial direction. When this occurs, the spring 13 is compressed and the sealing auger 10 is rotated. At the moment of release by the stamp 27 of the pressing chamber 30, i.e. when the baler outlet 26 is open, the sealing screw 10 under the action of the force of the spring 13 moves downwards and the periodic pulsed supply of the compacted material into the press chamber 30 rotates while simultaneously compressing due to a dynamic impact moving in the axial direction of the sealing screw 10. Fading oscillations of the latter caused by the disturbing force of the dynamic impact, help to clean the turns of the sealing auger working body and reduce the friction force between the compacted material and their turns. Likewise, compacted material is fed into the press chamber by a sealing screw 11. The economic effect of introducing the invention is achieved by increasing productivity. Claims of the invention A briquette press sub-press comprising a housing with an outlet above the press chamber of the press, supplying and sealing working bodies in the housing, characterized in that, in order to increase productivity, the sealing working body is made in the form of a driving screw, a hollow drive shaft with screw p-az, the screw shaft with a finger placed in the screw groove, while the screw shaft is mounted in the hollow drive shaft with the possibility of axial movement and is spring-loaded relative to this shaft.
