Description

The invention relates to the field of processing agricultural products and can be used for washing and grinding root crops.

A universal auger feed grinder is known (Patent RU No. 142728, publ. 06/27/2014), including a hollow body with a loading funnel, a feed auger installed in the body cavity, each turn of the helicoid of the feed auger is formed by two sickle-shaped knives, which are metal plates with cutting edges , made on the end arcuate working face and along the outer periphery, a grinding body made in the form of a knife, an unloading window covered by a deck

The disadvantage of this installation is the inability to wash root crops.

The purpose of the invention is to expand the technological capabilities of the installation by combining the processes of washing and grinding root crops.

This goal is achieved by the fact that the installation includes a washing zone, in which rotary nozzles are located diametrically on the horizontal axis of symmetry of the housing at an angle α to the vertical axis of symmetry of the housing, slots are made in the lower part of the housing of the washing zone, the installation is mounted on a frame consisting of four supports between which the tray is fixed, the bottom of which is made with slopes to the drain pipe, the installation includes a closed-cycle water purification system.

In FIG. 1 is a front view of a combined root washer and grinder with a closed circuit water treatment system.

In FIG. 2 shows section A-A in FIG. one.

In FIG. 3 shows a right side view of a combined plant for washing and chopping root crops.

In FIG. 4 shows a bottom view of the hollow body in the washing area.

Combined installation for washing and grinding root crops, contains a hollow body 1 with a loading funnel 2, a feed screw 3 installed in the cavity of the body 1, each turn of the helicoid of the feed screw 3 is formed by two sickle-shaped knives 4, which are metal plates with cutting edges 5, made on end arcuate working face and along the outer periphery, a grinding body 6 made in the form of a knife, an unloading window covered by a deck 7. The deck 7 is made in the form of a round separating plate with through holes of various sizes. The drive of the feed screw 3 and the grinding body, made in the form of a knife 6, is carried out by means of a gearbox 8. The installation includes a washing zone, in which rotary nozzles 9 are located diametrically on the horizontal axis of symmetry of the housing at an angle α to the vertical axis of symmetry of the housing, in the lower part of the zone housing 10 are made. into the slotted filter 16, then into the final (fine) filter 17 and subsequently into the storage tank 18. From the storage tank 18 under pressure created by the pressure increase module 19, purified water is supplied to the rotary nozzles 9.

Settling tank 14, deep pump 15, slotted filter 16, final (fine) filter 17, storage tank 18 and pressure booster module 19 constitute a closed-loop water treatment system.

The combined plant for washing and grinding root crops works as follows:

Root crops, coming from the hopper 2 into the hollow body 1, moving by the feed screw 3, are subjected to intensive treatment with water supplied under pressure of 6 ... 8 bar by rotary nozzles 9 connected to a closed-cycle water purification system.

Simultaneously with the washing, the root crops come under the action of two sickle-shaped knives 4 located on the 3 feed screw.

The process of destruction can be represented as the work of a wedge for crushing and breaking off.

In general, the process of separating the first part of the root crop from the main one can be represented as follows:

- at the first moment, the tip of both knives 4 "enter" the body of the root crop to a certain depth and experience the action of forces, while each tip of the sickle-shaped knife 6 is different:

- one of the sickle-shaped knives 4 will act as a whole as an instant center of rotation (support point), and the other will squeeze the smaller part of the root crop from the large one, while simultaneously rotating the root crop around the said center; at the next moment, the same sickle-shaped knife 4 will move into the partially turned root crop and go even deeper until the end of the destruction process;

- as a result of the separation of a part of the root crop from the main mass, the remaining part will change its position relative to the sickle-shaped knife 4 (due to rotation) and fall under the action of the following knives 4 after half a turn, and so on until the dimensions are comparable to those of the screw channel.

Further, the material goes out through the unloading window and, if necessary, can be additionally crushed with a knife 4, while the degree of grinding is regulated by a deck 7 with a corresponding through sector or the number of blades of a knife 6.

The presence in the installation of a washing zone with a closed-cycle water purification system will reduce labor intensity, increase productivity and save water consumed when preparing feed from root crops.

The use of rotary nozzles will ensure the supply of a flat powerful jet to the surface of root crops, due to which a scraper effect will be provided, as a result of which the efficiency of washing root crops will increase with economical use of the consumed liquid.
