Giving pipe 1, mounted, at its outlet an adjusting cone-shaped valve 2 mounted on a rod consisting of two rods 3 and 4 located along the length, mechanism 5 controlling valve 2 movement depending on juice flow, including pneumatic actuator 6, the membrane 7 of which with the upper rod 3 for c; the reciprocating movement to it, and the 8-time etching mechanism

The invention relates to equipment used in the sugar beet industry for metering liquid reagents, such as lime slurry.

The purpose of the invention is to improve metering accuracy.

The drawing shows a device for dispensing a lime slurry.

The device for dosing the lime suspension contains a feed pipe, an adjustment cone-shaped valve 2 mounted on its outlet, mounted on a brush consisting of two rods 3 and 4 arranged along the length, a mechanism 5 controlling the movement of the valve 2 depending on the flow rate of the juice. 6, the membrane 7 of which is associated with the upper rod 3 for communication, to it a reciprocating movement, and the movement control mechanism 8 1 of the valve 2, depending on the density of the lime slurry, yuchayuschy gear mechanism 9. The apparatus 10 is provided with a pulse atsii conical valve comprising a cam 11 and placed in the box 12, is rigidly associated with the upper core rod 3, the. the lower rod 4 of the rod is provided with a pusher 13 interacting with the cam 11 of the pulsation mechanism 10 and is connected by a threaded connection with the valve 2.

valve 2, depending on the density of the lime slurry, including gear 9. The device is equipped with a pulsation mechanism 10 of a cone-shaped valve 2 containing a cam 11 and placed in a box 12 rigidly connected to the upper rod 3, while the lower rod 4 of the rod is equipped with a pusher 13 that interacts with the cam 11 of the pulsation mechanism 10 and is connected by a threaded connection with the valve 2. 1 sludge.

and is driven in rotation by the actuator 14. The cam 11 is driven in rotation by the actuator 15 through the bevel gear 16 and the shaft 17. The outlet 18 of the feed pipe 1 is installed in a tank 19 having a plug in 20. The valve 2 is fitted with E guides 21. To maintain this valve in the closed position, a spring 22 is installed on the lower rod 4 of the stem, and a spring 23 serves to return to the initial position of the box 12. The driven gear 9 is mounted on supports 24.

The device works as follows.

When changing the flow rate of the diffusion juice, the signal from the flow sensor (not shown) is fed to the pneumatic actuator 6 of the valve control mechanism 5

2 depending on the consumption of juice, which moves down the upper rod

3 together with the box 12 by a certain amount. Together with the box 12, the shaft 17 of the cam 11 moves, together with the drive 15.

The cam. 11, pressing the pusher 13, moves the lower rod 4 to open the cone valve 2. This changes the flow of the lime slurry entering the container 19. From the suspension container it is discharged through the nozzle 20.

The signal from the lime lime density sensor (not shown) is fed to the actuator 14 of the mechanism 8 controlling the movement of the valve 2 in

depending on the density of the lime slurry, which rotates the lower rod 4 through the gear train 9. When the rod rotates, the rod additionally raises or lowers the valve 2 by. the expense of their threaded connection, thus changing the cross section of the outlet of the pipe 18, and changes accordingly the flow of lime suspension to the cleaning of the juice. Thus, the valve 2 continuously pulsates. Regardless of the operation of the pneumatic actuator 6 and the actuator 14, providing a more accurate dosing of the suspension.

Continuous pulsation of the valve 2 is provided by rotating the cam 11 and reciprocating movement of the lower rod 4, which interacts with the cam 11 through the thrusters 13 and with the pneumatic actuator 6 through the box 12.

The frequency of rotation of the cam 11 and the amplitude of the pulsation of the valve 2 can. be changed by changing the rotational speed of the actuator 15, as well as the profile and size of the cam 11.

Since the spring stiffness 23 is much greater than the spring stiffness. 22, the rotation of the cam 11 does not affect the position of the upper shaft 3 and the box 12.

The proposed device ensures the prescribed accuracy of the dosing of the suspension during the entire period of operation of all the mechanisms, since not 5
