Abstract

The invention relates to a device for shredding waste of enterprises of the construction industry and agricultural products and allows for an increase in the efficiency of grinding. The grinding device consists of a vertical casing formed by cylindrical drums: the upper 1 of larger diameter and the lower 2 of smaller diameter and conical shell 3 connecting them, and the shaft 4 with chopping elements knives 5, 6 and 7. Due to the fact that the crushing elements knives 5, 6 and 7 are located in the lower drum 2, are three-bladed, the blades of the upper knives 5 are bent up, the middle 6 are horizontal, the lower 7 are bent down and all of them are offset from each other in the horizontal plane, and With the drum 1 and the conical shell 3, plate knives 8 and 9, obliquely fixed on the drum 1 and the shell 3, are obliquely fixed in the housing during the grinding process intensive liquid flows are created (liquid is supplied from the dosing tank 11 or separated from the raw material - juice, squeezed out of agricultural products), providing high grinding efficiency. 1 hp ff, 4 ill.

Description

The invention relates to the field of grinding and can be used in the construction industry and agriculture.

The purpose of the invention is to increase the efficiency of the grinding process.

Fig. 1 shows a grinding device, a general view, aligned with a cut along the main assemblies; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. one; in fig. 4 shows the configuration and arrangement of the knives.

The grinding device comprises a vertical housing formed by cylindrical drums of a larger — upper 1 and smaller — lower 2 diameters interconnected by a conical obmeyka 3, and shaft 4 installed in the lower drum with grinding elements in the form of three-blade knives 5-7. The blades of the upper knives 5 are bent up, the middle knives 6 are made horizontal, and the lower knives 7 are bent down, all blades being displaced one relative to the other in a horizontal plane at an angle of 60 °.

The upper drum 1 and the conical shell 3 are provided with plastic knives fixed on their inner surfaces, respectively, 8 and 9, and these knives 8 and 9 are installed obliquely in opposite directions on the drum 1 and the shell 3K to the upper drum 1 by means of pipe 10 connected to the dosing tank 11c , while in the drum 1, in the upper part a restrictive ring 12 is fixed and a drain hole 13 is made, there is a hatch 1,

The lower drum 2 has an inclined bottom 15 and an opening 17 with a tray 18 blocked by a valve 16. A trolley 19 is installed under the tray 18. The shaft 1 is connected to the drive 20. The grinding device operates as follows.

- The required amount of liquid is poured into the casing of the dosed tank 11, the drive shaft 20 is turned on with the knives and the chopped raw material is loaded through the hatch 14 — waste of cardboard and ruberoid production (cardboard, waste paper, roofing felt, etc.).

The shaft L rotates at a slow speed when the raw material is loaded, after the end of the loading (the hatch 1A closes) from high to 2500-3000 rpm.

Inside the casing, a circular flow is created by the knives and the raw material particles are intensively crushed by these knives as well as by the blade knives 8 and 9 on the walls of the drum 1 and the shell 3.

After completion of the process of grinding the raw material, the resulting suspension is discharged by opening the valve 16, through the opening 17 at the bottom of the drum 2 through the tray 18 to the trolley 19.

When grinding agricultural products: potatoes, beetroot, carrots, etc., they are loaded into the body, then they supply liquid in advance. The required amount of liquid can be supplied from the dosing tank 11 already in the grinding process.

The grinding of various raw materials in this device is highly efficient and does not require the use of thermal energy.

Claims (2)

1. A grinding device comprising a vertical body formed by cylindrical drums of larger — upper and smaller — lower diameter, connected by a conical shell, and a shaft mounted in the housing with grinding elements, so as to increase the efficiency of the grinding process The grinding elements are located in the lower drum and are made in the form 51551WO three-blade knives, the upper blades of which are bent upwards, the middle ones are made horizontal, and the lower ones are bent downward, and the blades of the knives have an angular displacement one relative to the other in the horizontal plane. 2. A device according to claim 2, characterized in that the upper drum and the conical shell of the housing are provided with plate-like knives fixed obliquely on their inner surfaces in opposite directions on the drum and the shell. 13 fig 2 Fi & 3 Phia.4
