Abstract

The invention relates to equipment for the washing of root crops and the separation of impurities from them. The aim of the invention is to improve the quality of washing tanks. After loading the tub 2 of the root crops, the latter are exposed to a directional flow of fluid created by rotating the blade drum 8 and the bent plates 9 and 19 and the curved wall A of the body of the bath 2. In the movement area of the roots under the guide plate 20 they are exposed to air bubbles released under pressure from system 10 fluid flow turbulence. 2 Il. from $ sl with / WO8a soo i4 CO OO SP

The invention relates to equipment for treating root and tuber crops, namely, plants for washing and separating root crops and vegetables, and can be used not only in equipment for washing and subsequent processing or preparing for sale, but also for washing and subsequent processing for long-term storage using an antiseptic.

The purpose of the invention is to improve the quality of washing.

The introduction of the elements, their constructive implementation and the connection provide the creation of such conditions for directing the flow of liquid, which seeks to damage the surface of the root-and-vegetable crops and makes it possible to eliminate the cost of manual labor for the separation of stones from the root-and-vegetable crops.

FIG. 1 shows a plant for washing of root crops, side view, section; in fig. 2 is a view A of FIG. 1. The plant for washing of root crops has a frame 1c installed on it by a drive and a bathtub 2, which has a tray 3 of load, a curved wall 4, a sump 5 and a node 6 for throwing liquid. In the bathtub 2, a roller conveyor 7 is partially submerged in liquid, the rollers of which are covered with an elastic material. Under the roller conveyor 7, a rotary drum 8 is mounted for rotation, the blades of which are rigidly attached perpendicular to the tangent of the shaft. Under the drum 8 s behind: a curved plate 9 is fixed on it to the bath 2, which serves to create a directed flow of liquid. Above the drum 8 in the bath 2 a system of air turbulization of the fluid is fixed.

The air turbulence system 10 of fluid consists of a tank with ducts bred above the liquid level in bath 2, with one wall of this tank, curved and positioned with a gap from the drum 8, having a slit-like outlet 11 located at the beginning of the -: drum rotation 8, i.e. in the suction zones. Other walls of the tank are made with a slope that prevents the accumulation of impurities on them. To separate the liquid flow from the main mass of the liquid in the bath. 2 urtanavli

The partition 12, on which the valve 13 is fixed, is adjustable for the width of the opening 14. At the same time, the installation is equipped with a perfuming device 15, coming into effect from the pump 16, rinsing device 17, a plug 18 that closes the window for discharge of impurities, and fixed to the bath 2 above the conveyor 7, the curved visor 19 and the guide to the slit 20, the bottom surfaces of which are equipped with soft bristles or elastic material, and the guide 20 is fixed with the possibility of adjusting the clearance of the conveyor 7, depending on ida root crops to be washed.

The installation works as follows.

Bath 2 is filled with fluid from the water supply system to the required level. As the drum 8 rotates, a vacuum is formed between the plate 9, the paddle and the shaft of the drum. A fluid flow rushes into this volume, which is closed by the next blade and moves along the curved plate 9, then is ejected into the space between the partition 12 and the curved wall 4 of the bath. The curved wall 4 directs the flow to the opening 14. As the blades move one after the other, a continuous flow of liquid is formed, the force of which is determined by the speed of rotation of the drum 8. The rotation speed is selected so that when the root and tuber crops are fed through tray 3, the load in the bath 2 the root crops are dropped on the curved visor 19 and then turned on the conveyor 7, and the stones overwhelmed the flow.

they fall into the hole 14 and then into the sump 5 of the bath 2. The same vacuum is created between the paddle, the shaft of the drum 8 and the system 10 of turbulization. liquids. At the same time, along with the liquid coming from the bath into the indicated space, air is sucked through the slit-like outlet port 11, and liquid is sucked out of the air turbulence system 10, which, prior to switching on the drum 8, fills the tank and air ducts of the system 10 to liquid network in the bath 2, the air mixed with the water moves the blades along the Vd1-bent wall, is thrown into the bath 2 and floats under the rail 20. As it rushes towards the exit, the air passes along the rail 20 and agitates Roots, located on a roller conveyor 7, improving the quality of their washing. By moving the roller conveyor 7, the root crops fall under the shower device 15. At the same time, the conveyor rollers move lio to the guides and rotate around their axis due to friction about them, thereby rotating the root crops that are washed from the Bcek sides. The impurities washed out on the roller conveyor 7 fall between the rollers and precipitate into the settling basin 5, from which they periodically remove the opening of the plug 18. And the roots and tubers before unloading from the plant are rinsed with clean water from the aqueduct rinsing device 17. impurities that float up in the tray 3 area of the load and 11 move to the space above the curved visor 19 and the flow guide 20 j directed into the slit 21 and caused by the ejection of the stream passing under the curved trump com 19. vsheukazannom space HA kaplyvayut.s and they are removed periodically.
