Description

The invention relates to equipment for the food industry, namely, devices for washing tubers. The known beet washer containing successively spaced and separated by the chamber wall, inside which are installed devices for mixing and moving the beets, coming out of the Horizontal Shaft and the fists planted on it, lobed throwers of beets, a device for trapping light impurities, placed on the second chamber And The disadvantages of this beet washer are the additional water consumption during the periodic cleaning of the stone trap as well as the complexity of the design of beet washer, which requires constant maintenance. A device is known for washing the crust of the tubers, which contains successively arranged chambers of the pre-cast and final washing with perforated drums and discharge vanes and a stone trap 2. However, in this machine, there is an additional consumption of oxen and loss of root crops associated with the periodic cleaning of the stone trap. The purpose of the invention is to reduce water consumption, loss of root crops and simplify the design of the device. This goal is achieved by the fact that, in a washing device, a non-fruit rootcage club containing successively located preliminary and final washing chambers with perforated drums and discharge vanes and stone trap placed in them, the stone trap is located between the preliminary and final washing chambers and consists of a funnel with a spout and located under it a compartment with an inclined conveyor installed in it, the tape of which is provided with ribs placed in pairs at an angle to one another, symmetrically About the longitudinal axis of the belt and with a gap between them for the passage of my fluid, the stone trap is connected to the final washing chamber by means of a circulation pump, the ribs on the conveyor belt are set at an angle of 90-160 and the clearance is made in the form of a tration, the greater basis of which facing the conveyor belt, Ya FIG, 1 schematically shows an npejEinaraeMoe device, a general view of i in FIG. 2 is the same longitudinal section in FIG. 3; a section A-L in FIG. one; in fig. 4 is a view B in FIG. 3 in FIG. 5, Breeze B-B in FIG. 4, the proposed device comprises successively located chambers 4 and 5 of the prewash chamber 4 and 5 sequentially separated by walls 1-3 and respectively, between which the stone trap 6 i is located. raw materials consisting of coaxial shafts 7 and 8 of bar drums 9 and 10 mounted on them. Shafts 7 and 8 are installed in slide 11, are interconnected by clutch 12 and receive a torque from drive 13 through clutch 14. Each drum is supplied with steam blades 15 and 16. Before the drum 9 there is a collector with. nozzles 17 for supplying directed water jets to the drum 9. The final washing chamber 5 is equipped with a washing tub 18. The stone trap 6 consists of a funnel 19 ending with a nozzle 20, disposed of. placed under the funnel of compartment 21 and installed in this compartment inclined conveyor 22. Compartment 21 is bounded by side walls 23 and 24 of the device, walls 1 and 2, funnel 19 and bottom 25. Tape 26 inclined conveyor 22 is equipped with ribs 27 arranged in pairs and symmetrically relative to of the center of the belt 26 and the angle between them forming an angle of between 90 and 1BO®. Between each pair of ribs 27 on the belt 26 of the conveyor 22 there is a gap 28 for the flow of water. The gap 28 is formed by bevels 29 on the ribs 27 and has the shape of a trapezoid, the larger base of which is facing the belt 26 (the size L is larger than the size E). A branch pipe 30 is installed in the compartment 21 to supply water to the stone trap 6. The device is equipped with a pump installation 31 to create an upward flow of water in the funnel 19 of the brick room 6 and a valve 32 for adjusting the water flow rate. A filter 33 is installed on the suction line to prevent the pump unit 31 from clogging. The device is equipped with trays 34 and 35 for loading and unloading raw materials. In chamber 3, an overflow pipe 36 is installed to maintain a constant water level in the wash tub 18 and the stone trap 6. The device is provided with hatches 37 for sanitizing and draining the waste water. . The device works as follows. In the stone trap 6 and the camera ends-. A washing machine 5, which communicates through a rectangular window in the wall 2, is poured iodine to the level of an overflow pipe 36. Potatoes are fed into the drum 9 through the loading tray 34. Simultaneously, the drum 9 is pumped out of the washing unit 18 by a collector with nozzles 17 into the drum 9 jets of water.

When the drum 9 is rotated, the potato tubers rub between themselves and about the rod of the drum 9, as a result of sticking to the tubers, the earth is separated from them and together with sand and small stones under the action of directed water jets from the collector with nozzles 17 is washed into the collection (not shown ), equipped under the device.

Due to the small inclination of the device in the direction of discharge, the potatoes are moved along the drum 9 and a pair of blades 15 are reloaded into the stone trap b through a rectangular window in the wall 1.

In compartment 21 of stone catcher 6, water is pumped through pipe 30 by pumping unit 31, the gap of which is from washing tub 18. In the stone bath funnel 19, an upward flow of water is created which keeps the tubers in suspension.

Due to the large specific gravity of the stones located in the potato, they are lowered into the lower part of the funnel. 19 With the help of a valve 32 this water flow rate is established, at which the stones are completely separated from the potatoes. The operation of the pumping unit 31 continues while there are potatoes in the machine. This eliminates the possibility of potato tubers getting into the compartment 21 of the stone trap 6 and removing them from the device along with the stones.

The stones get into the pipe 20, which ends up the funnel 19, and from it - to the belt 26 of the inclined conveyor 22. Through the ribs 27, located on the belt 26 pairwise, symmetrically relative to its center, at an angle to each other 90-160 °, the stones reliably held on the belt 26 of the inclined conveyor 22, which is transported from the device.

The bevels 29 on the ribs 27, forming gaps 28 in the form of a trapezoid, the larger base of which is facing the belt 26, provide a complete and rapid flow of water along the belt 26 into the stone trap b.

Potato tubers carried along by the flow of water through the rectangular window in the wall 2 fall into the drum 10. As the stone-catcher 6 is located in front of the final washing chamber 5,

5 do not fall into the drum 10. During the rotation of the drum 10, the potatoes in it 10 are washed from the remnants of contaminants and a pair of blades 16 are unloaded on the tray 35 to be removed from the device. Waste water enters the collection equipped under the device (not shown) and transports for filtration.

The proposed design of a device for washing root crops using an inclined conveyor for the continuous removal of stones reduces water consumption, reduces maintenance costs, simplifies the design of the device as a whole, and also eliminates the loss of raw materials with stones when they are removed.

In addition, the placement of the stone trap in front of the final washing chamber prevents stones from entering into it more, which reduces the burden on the working organ and reduces the consumption. power and also excludes the possibility of mechanical damage to the raw materials in the final washing chamber
