SU392965A1 - DISPENSER OF THE SYSTEM MIKHAILOV-L ISAI - Google Patents

Description

one.

A dispenser of liquid, viscous and pasty materials is known, containing a constant-level supply tank with a stirrer and a DRAIN pipe, under which a variable-section nozzle is placed.

However, the known dispenser does not provide sufficient metering accuracy.

In order to eliminate the indicated deficiency in the proposed dispenser, the nozzle is made in the form of a truncated cone facing a large base towards the intake of the material being metered, and is provided with a drive of rotational motion.

In order to increase the return pressure on the inner wall of the nozzle, the blades are strengthened.

The drawing shows the proposed dispenser.

The dispenser contains a supply tank / with a pipe 2 for supplying the dosing material and the mixing device 3 to it.

The supply tank / is equipped with an overflow pipe 4 to maintain a constant level of the material to be dosed and a drain pipe 5 with a locking device 6. Under the locking device 6 there is a nozzle 7, made in the form of a truncated cone, with a large base facing the inlet side of the material being metered. Nozzle 7

2

connected to the drive 8 rotational motion.

In order to increase the return pressure on the inner wall of the nozzle, the blades are strengthened (not shown in the drawing).

The dispenser works as follows.

The dosing liquid is loaded into the container 1 through the nozzle 2 and in the presence of suspended solid particles in it, the contents of the container are mixed using the device i. The liquid level in the tank I is kept constant by draining excess liquid through the pipe 4. The dosing material from the tank 1 through the drain pipe 5 and the locking device 6 enters the nozzle 7, which is rotated by the drive S. When rotating the nozzle 7, the liquid is metered parts of the hole to the lining, thereby creating a pressure opposite in the direction of the pressure of the metered flow.

The presence of blades on the inner surface of the nozzle 7 increases the speed., The rotation of the dosed flow and lbm self increase the back pressure and reduce & D < > g & d of the dosed material;

The change in the consumption of the material being metered is achieved — by way of - 1 change of nt — the speed of rotation of the nozzle.

Claims (2)

1. A batcher of liquid, viscous and pasty materials, containing a constant level feed tank with a stirrer and a drain pipe, under which a variable cross section nozzle is located, characterized in that, in order to improve metering accuracy, the nozzle is made in the form of a truncated cone facing more base in the direction of entry of the dosing material, and is provided with a drive of rotational motion. 2. A dispenser according to claim 1, characterized in that, in order to increase the return pressure, the blades are fixed on the inner wall of the nozzle.
