Description

The invention relates to devices for automatically controlling the density of liquid media, for example, solutions and suspensions of potash production.

Measuring vessels are known, in the form of a funnel or vessel with overflow, in which the primary transducers of density meters of liquid media are placed. ..

The controlled medium is supplied to the lower part of the vessel, moves to the top, is poured over the edge and returns to the process. The primary transducer (float, piezometric tubes, etc.) is introduced into the measuring vessel from above and immersed in the controlled medium to a certain depth.

The known measuring vessels do not allow to select and set the required speed of the upward flow in the vessel, depending on the properties of the controlled medium.

In addition, the vessels can clog with a solid phase of the medium under study at the termination of its flow.

The purpose of the invention is to develop a simple and reliable vessel with a stabilized flow controlled environment and the ability to control the flow rate.

The goal is achieved due to the fact that the outlet nozzle is mounted concentric with the receiving and measuring (serving to accommodate the primary transducer of the densitometer) cameras between them. This ensures double stabilization of the flow rate: it maintains a constant level in the receiving chamber, which

determines the upstream flow rate gz of the measuring chamber.

The drawing shows the proposed measuring vessel, a longitudinal section.

The vessel consists of an inlet nozzle 1, a receiving chamber 2, an outlet nozzle 3 with a nozzle 4 being moved along its height, a measuring chamber 5 and a drainage hole &

A measuring chamber 5 connected in the lower part with a receiving chamber is located inside the outlet nozzle.

The measuring chamber (or discharge nozzle) is height-adjustable; thus, the difference in two levels can be changed depending on the properties of the medium and the size of the solid phase from zero to the limiting value,

A drain hole, which can be made adjustable in diameter to facilitate adjustment, prevents clogging of the vessel in the event a fluid supply is cut off. I Source medium (slurry, liquid phase) is directed through the inlet 1 to the receiving chamber 2, from which it is discharged to the discharge nozzle 3 through the annular nozzle 4 being moved in height. Under the action of the liquid column created in the receiving chamber, the medium is poured from the measuring chamber 5 also into the discharge port 3. The required flow rate is provided by moving the annular nozzle 4. Hole b, through which chambers 2, 3 and 5 communicate, is used to descend on to the medium in the vessel after stopping its supply through the inlet discharge pipe 1.
