Description

The invention relates to agriculture and, in particular, to equipment for granulating and dewatering sapropels and mixtures.

The purpose of the invention is to increase productivity in the production of granules of various shapes and sizes.

A device for granulating and dehydrating sapropels and mixtures is illustrated in the drawings, in which Fig. 1 is a perspective view; figure 2 is a section aa in figure 1; in Fig. 3 - the same, but with the plug installed; Figures 4 and 5 show a set of cutting knives; figure 6 - retaining ring.

The device for granulating and dewatering sapropel and mixtures consists of a housing 1, in which a screw 2 is placed, having a hollow perforated shaft 3, bearing perforated blades A. The pitch of the screw 2 of the screw 2 is uniformly reduced to the discharge window 5, made in a movable figured plate 6, moved by a jack 7. The source material enters through the intake pipe 8, and is issued through the discharge pipe 9 or through a removable perforated matrix 10. Outside the matrix 10 mounted on the shaft 3 removable knives 11, which are rigidly fastened They are connected to the shaft 3 by means of a retaining ring 12 having protrusions 13 that extend into recesses 14. made on knives 11. Instead of a removable matrix 10, a plug 15 can be installed. Fastening of the matrices 10 or plug 15 to the housing 1 is carried out using screws provided on the grips 16, and which are placed matrix 10 through the recesses 17 with the subsequent rotation of the matrixes at a certain angle. The circlip 12 is attached to the shaft 3 using bolts or other means.,

A device for granulating and dehydrating sapropel and mixtures works as follows.

Moistened sapropel or mixtures containing 50-60% water enter the device through the inlet 8, from where they are captured by the blade 4 of the rotating screw 2 and transferred to the discharge

window 5. In this case, the material is dehydrated to the desired condition. The water released from the water flows outward inside the shaft 3.

There are three modes of operation of the device.

1. With the plug 15 installed and the unloading window 5 open, dehydrated sapropels or mixtures with a total mass are discharged through the outlet pipe 9.

2. With a closed discharge window 5 and a perforated matrix 10 with knives 11 installed; granules of various shapes and sizes are dispensed. The shape and size are determined by which dies and which knives are installed on the device.

3. If the discharge window 5 is not fully open and the matrix 10 with knives 11 is installed, material is simultaneously discharged, both in the form of granules and as a single mass from the discharge pipe 9. The degree of dehydration of sapropels or mixtures is also regulated by changing the cross section of the discharge window.
