Abstract

Usage: instrumentation. SUMMARY OF THE INVENTION: In the supply container 1, a float 2 is placed, with which the inlet end 5 of the flexible outlet pipe 3 is connected. Above the float there is an elastic tube 8. A flexible cable 7 is passed through it, connecting the inlet end 5 of the flexible outlet pipe with an adjustable backward mechanism 6 -receive flax moving. The elastic tube 8 is connected at one end to an abutment on the float 2, and at the other end to a fixed support located outside the consumable container, on which the mechanism 6. 1 is mounted.

Description

FIELD OF THE INVENTION This invention relates to techniques for the use of a fluid-chemical medium used in the chemical, mining and processing and other fields of industry. In particular, it relates to devices for subsidizing liquid by gravity from tanks of a variable level.

A metering device is known in which the tank is provided with a flexible flow tube with a selective tank mounted on a float. In this device, the receiving cup is provided with (with the possibility of vertical movement) a nozzle with grooves for supplying liquid. Moreover, in the process, this pipe is in a fixed position,

The disadvantage of such a device is the unregulated dosage during operation, which causes intervention at all times to readjust the system, due to the need to change the dosage, the complexity of the device,.

Another metering device comprises a consumable container with a float disposed therein and a flexible outlet pipe, the inlet end of which is connected to the float and a controlled reciprocating movement mechanism.

In the use of known solutions: it is impossible to change in the process of continuous dosing of a liquid its quantity per unit time;

during continuous dosing, it is not possible to switch to any new capacity when used in automatic control systems, which does not allow you to quickly mix into the dosing process for any randomly varying capacity.

In addition, structurally sampling elements (selection of the length of the connection between the float and the receiving chamber or disk, the selection of the cross section of the bore by opening the diaphragm of the receiving chamber, the use of a metal pipe with a hinge, etc.) are complex and require accuracy when manufacturing, installation, calibration, operation, all this complicates the whole device.

When used in technological processes leading to overgrowth and clogging of the inlet section, it violates one or another established dosage regimen.

The purpose of the invention is to increase efficiency by enabling dose adjustment during operation.

The goal is achieved by the fact that in the liquid dispenser containing a flow rate

a flexible container with a float and a flexible outlet located in it, the inlet end of which is connected to the float and an adjustable reciprocating mechanism, an elastic tube located above the float and a flexible cable passed through it, through which the inlet end of the flexible outlet is connected a mechanism of adjustable reciprocating movement mounted outside the supply tank on a fixed support, and with which one of the ends of the elastic tube is fastened to the other end connected fired with an emphasis made on the float.

The drawing shows a liquid dispenser,

It contains a supply tank 1 with a float 2 located in it and a flexible outlet pipe 3, which is attached to the float 2 by means of a suspension 4, the input end 5 of the flexible outlet pipe 3 sv - with a float 2 and a mechanism b, adjustable reciprocating which is mounted outside the supply container on a fixed support, for example, on the outside of the supply container housing 1 (this is not a necessary condition, if necessary, it can also be located on some other stationary support; it can also be controlled both on-site and remotely).

The inlet end of the flexible outlet pipe 3 through a flexible cable 7, passed through an elastic tube 8 located above the float 2, is connected to the adjustable movement mechanism 6, installed outside the supply tank, and representing, for example, a lead screw 9, located in the support sleeve 10. The movement mechanism is fastened to one of the ends of the elastic tube, the other end of which is connected to a stop made on the float,

The liquid dispenser works as follows

In the initial state, when the tank 1 is filled with liquid, the lower boundary of the inlet 5 of the flow tube 3 coincides with the boundary of the liquid level, there is no drain ..

In order to perform dosing by means of the adjustable movement mechanism 6, they act through the elastic 5 tube against the stop on the float, thereby weakening the initial tension of the flexible cable 7, which corresponds to the value of the set dosage dose, due to which it is exposed to a suspended load (input end 5 of tube 3 ) together with

it will move until a new equilibrium state is reached by the set dose of HCJBKH. In this way, the inlet of the nozzle partially immerses, into the overlapping part of which the liquid flows by gravity in proportion to immersion, or the installation size1.

The dose setting value by mechanism 6 can be carried out both manually and automatically according to a predetermined program.

This design of the dispenser eliminates external energy consumption and can be used for dispensing any type of liquid.
