SU113688A1 - Dispenser for supplying reagents to the "pachuka" vats during hydrometallurgical processes - Google Patents

Description

For the dosage of reagents, the packs of the pack are applied; volumetric containers with a certain volume, which are filled with the necessary reagent. Then it is displaced from the measuring tank by compressed air into the packuch bag.

The proposed dispenser operates at a constant flow rate per unit of time at a constant pressure and a constant outflow hole, which automates the operation of dispensing liquid reagents into pachuca tanks.

The liquid reagent dispenser consists of:

a) a pipe, in which it is kept constant by means of a pressure regulator;

b) a stop valve controlled by time with noMonin electrical time sensor, the scale of which is calibrated directly in units of flow. The valve is made of anti-corrosion material (vinyl plastic);

c) system of connecting pipelines.

In the dispenser there are no measured containers and an instrument, measuring the number of reagents. Accounting is carried out according to the opening time of the chamber.

A schematic diagram of the dosage of reagents in vats of a “pack by means of the dispenser described is shown in the drawing.

According to this scheme, from the collection and a 1 of the reagent by the pump 2, the liquid is transported via the ring pipe 3 and is returned back to the collection.

In order to maintain a constant backpressure of the fluid in the annular pipe, a pressure regulator 4 is installed at its end (drain), working up to itself. From the ring piping there is a wiring through the tanks of “Iachuka 5.” With a constant pressure and a constant outflow hole 6, the flow rate of the liquid depends on the flow time of the pipeline. In this case, the dosage of the fluid is controlled by a time-controlled valve 7.

The opening and zykryi klpaip is regulated by the e / 1 CRII .M; uiT4HKo B) e. 8. The dachchika time scale is shown directly in units of (.) And liquid.

In case of a need to make a change in the flow rates, it suffices to change the outflow hole and make an amendment to the time sensor.

In cyclical technological processes, this installation can be included in the system of software control by technological process,

PREDIMST AND N ABOUT THIS

A dispenser for supplying reagents to the packs of a pack in hydraulic metallurgical processes, characterized in that, in order to automate the process of controlling reagent consumption, tanks with a constant level for maintaining pressure were replaced by an unchanged pipe with a pump and pressure regulator, lead with an electric time sensor.
