Description

The invention relates to the equipment of the sugar beet industry and is intended to dispense liquid reagents into juice, such as lime slurry.

A device for dispensing a lime suspension is known, comprising a container for receiving a dosed suspension, a branch pipe for supplying a suspension, a conical valve installed at the outlet of the branch pipe to regulate the quantity of lime suspension supplied, equipped with two coupled rods for returning it. translational movement, arranged vertically along one axis. and rod drives However, the device does not allow dosing and mixing of the suspension with juice at the same time.

A pipeline consisting of horizontal and vertical sections for supplying lime suspension, a container for receiving a dosed suspension, installed in a vertical section of the pipeline with the possibility of reciprocating movement of a rod to a conical valve fixed at its lower end to regulate the hearth and lime suspension, juice supply and valve control mechanism. However, in the known device there is no possibility of simultaneously mixing with the juice suspension with dosing and thus improving the process of distributing the suspension in the juice.

The purpose of the invention is to carry out simultaneously with the dosing of mixing with the juice suspension and thus improving the process of distributing the suspension in the juice.

Figure 1 shows the device, a longitudinal section; figure 2 - section aa in figure 1.

The device includes horizontal 1 and vertical 2 pipeline sections for supplying lime suspension, a tank 3 for receiving a dosed suspension, mounted in a vertical pipeline section 2 with reciprocating movement of a rod 4 with a conical valve 5 fixed on its lower end to regulate the flow of lime suspension, Juice supply means and movement control mechanism b by valve 5. Juice supply means contains a similarly designed pipeline 7 for juice supply, vert Calne portion 8 which is mounted coaxially with the vertical portion of the pipeline 2 for supplying limestone slurry to form therebetween an annular space 9 for the passage of juice, and mounted on a groove at the lower end of the vertical pipe portion 2 for supplying limestone slurry conical valve 10 for controlling the supply of juice. The stem 4 with a conical valve 5 for regulating the supply of lime slurry is mounted rotatably around its axis simultaneously with its reciprocating movement and provided with guide rods 11, and the conical valve 10 for regulating the flow of juice has channels 12 for accommodating the guide rods. The control mechanism b is connected with the stem 4 through the hinged joints 13 and 14, as well as through the coupling 15. In the section of the rod 16 there is a gear 17, which is included in

the engagement with the toothed rack 18 connected to the actuator 19. The mechanism 6 and the actuator 19 can be, for example, pneumatic. There is a gear on the rod 4 on the splines

the wheel 20. engages with the gear 21. The latter is connected with the reversing electric motor 22 to rotate the rod 4. The coupling 15 includes a guide bushing 23 freely mounted in the housing 24, and

0 valve 10 is provided with a sealing ring 25.

The device works as follows.

When changing the flow rate of diffusion

5, the signal from the flow sensor (not shown) is fed to a reversible electric motor 22, which rotates the lower stem 4, and with it the valve 5, as a result of which the vertical rods 11 rotate around the circumference. The direction of rotation of the rods 11 around the circumference depends on the phase of change in the flow rate of the juice. Since the vertical rods 11 are passed through the through channels 12, when they rotate

5, together with the valve 5, the valve 10 also rotates, which simultaneously moves progressively due to the threaded connection of this valve with the pipe 2.

The supply and correction of the supply of the fine suspension is carried out as follows.

Depending on the deviation of the ratio of the cost of juice and lime suspension from the value handed over to mechanism 6

5, a signal is received, as a result of which the stem moves valve 5, which changes the flow of lime slurry to the cleaning of the juice. If the density of the lime slurry changes, then the slurry density meter (not

0 shown) receives a signal to the side drive 19.

The side drive 19 moves the rail 18, which rotates the gear 17, and with it the upper rod 16.

5 Depending on the direction of movement of the rail 18, the end of the upper rod 16 will twist (unwind) into the sleeve 23 of the coupling 15, shortening (lengthening) the total length of the rod in proportion to the change in density of the lime slurry, which leads to an additional decrease (increase) in the supply of the suspension for cleaning. At the exit of the diffusion juice from section 8 and lime

5 suspension from section 2 they are mixed. Since the mixing of the juice streams and the suspension is carried out in the form of undissolved jets, the process of distributing the suspension in the juice is thus improved.
