RU218865U1 - COMBINED DEVICE FOR WASHING AND GRINDING ROOTS - Google Patents

Abstract

The utility model relates to the field of processing agricultural products and can be used for washing and grinding root crops. The combined device for washing and grinding root crops contains a hollow body with a feed funnel. Rotary nozzles are located on the horizontal axis of symmetry of the body at an angle α to the vertical axis of symmetry of the body. Slots are made in the lower part of the body. The feed auger is installed in the housing cavity, knives are staggered on the front part of the helicoid of the auger, a replaceable grinding body is made in the form of a knife and fixed on the shank of the shaft installed coaxially inside the feed auger, with the possibility of joint or independent rotation relative to the latter, an unloading window, overlapped by a deck made in the form of a replaceable separating plate. The device is mounted on a frame consisting of four supports, between which a tray is fixed, the bottom of which is made with slopes towards the drain pipe. The device includes a closed cycle water purification system. The screw helicoid in the area under the rotary nozzles is made perforated. The presence of perforation on the helicoid of the auger will improve the quality of root crops washing.

Description

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

A combined installation for washing and grinding root crops is known (Patent No. 2755164, pub. 09/13/2021, Bull. No. 26), including a hollow body with a hopper, on the horizontal axis of symmetry of the body at an angle α to the vertical axis of symmetry of the body, rotary nozzles are located, in slots are made in the lower part of the body, a feed auger is installed in the cavity of the body on the front of the helicoid of the auger, knives are installed in a checkerboard pattern, a replaceable grinding body is made in the form of a knife and fixed on the shank of the shaft installed coaxially inside the feed auger, with the possibility of joint or independent rotation relative to the latter, the unloading window, covered by a deck made in the form of a replaceable separating plate, the device is mounted on a frame consisting of four supports, between which a tray is fixed, the bottom of which is made with slopes to the drain pipe, the device includes a closed-cycle water purification system.

The disadvantage of this installation is not enough high quality washing of root crops.

The technical result of the utility model is to improve the quality of washing root crops.

The specified technical result is achieved by the fact that the screw helicoid in the area under the rotary nozzles is made perforated.

In FIG. 1 is a front view of a combined device for washing and grinding root crops.

In FIG. 2 is a left side view of a combined device for washing and chopping root crops.

In FIG. 3 shows a bottom view of the hollow body in the washing area.

A combined device for washing and grinding root crops, contains a hollow body 1 with a loading funnel 2, on the horizontal axis of symmetry of the body at an angle α to the vertical axis of symmetry of the body there are rotary nozzles 3, in the lower part of the body 1 slots 4 are made. a screw 5 having a perforation on the helical surface in the area under the rotary nozzles 3. On the front part of the helicoid of the screw 5 knives 6 are installed in a checkerboard pattern. with the possibility of joint or independent rotation relative to the latter. Unloading window 9, covered by a deck 10, made in the form of a replaceable separating plate. The device is mounted on a frame 11, consisting of four supports, between which a tray 12 is fixed, the bottom of which is made with slopes to the drain pipe 13. Through the drain pipe 13, the waste water enters the sump 14, from which the deep pump 15 is first supplied to the slotted filter 16, then to the final (fine) filter 17 and subsequently to the storage tank 18. From the storage tank 18, under pressure created by the pressure booster module 19, purified water is supplied to the rotary nozzles 3.

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

Combined device for washing and grinding root crops works as follows.

The root crops loaded into the funnel 2 are fed forward by the auger 5 into the washing zone, pre-chopped by knives 6, located in a checkerboard pattern on the front of the helicoid of the auger 5, where they are intensively treated with water supplied under pressure of 6 ... 8 bar by rotary nozzles 3 connected with a closed cycle water purification system. Approaching the unloading window 9, the main grinding of root crops occurs with a knife 7 rotating at the end of the shaft 8. Then the material exits the device, being additionally crushed by the counter-cutting knives of the deck 10.

The presence of perforation on the helicoid of the auger will improve the quality of washing root crops.
