Description

This invention relates to the mechanization of permeative processes in. Chemical industry and intended for the dosing of the components of the charge at sinter plants.

A device is known for the eEtomatic dosing of components of an aggregation charge, including weight sensors, a performance regulator-1 torus, registrars, and a multichannel unit for calculating expenditure coefficients of components, to which the weight controllers of components and the charge composition regulator are connected in parallel.

However, in a known device, a signal that continuously goes from the metering device changes its values over time, and this, in turn, necessitates continuous non-recalculation in the multichannel unit for calculating the charge charge coefficients and continuous changes to setting the flow controllers. As a result, the device is under constant disturbance. In ne.m, transients arise, the nature of which is different for different materials and the level of disturbances is different. In this connection, the prescribed weight ratio of the com monity of the disinfectant is violated and the dosing is lost.

The purpose of the invention; It is a novelty of sustainability mode.

Dt of this. Between the weight sensor of the dispenser I by the unit for calculating the coefficients of the flow of the flow of the system a.chadogo-discrete flow integrator KONiHoneuTOB LIJIJXTH.

The drawing shows a block diagram of a device for the automatic dosing of sinter charge components.

The device consists of a dispenser /, ana.-yyudiskr.e1yogo integrator 2, unit 3 load} wc-n, chemical analyzer 4, block 5 calculation of flow rates, setpoint 6 quality indicators of the finished sinter, regulator 7 with unit 8, analog-dns and integrated 9 and block 10 calculation of the coefficient of discharge.

The structure works as follows.

The weighed bulk material is continuous) iBHO is fed to a conveyor belt of weighing dispenser at constant speed and with a constant speed. The weight of the material is converted into an electrical signal by a weight sensor and fed to the input of an analog-discrete integrator 2 (for example, a main or a leading component), which 1 integrates a continuous component peso. The output of the analog-dispatcher integrator 2 is connected to block 5. The calculation of the charge consumption coefficients, the information to which is transmitted through this channel. To the input of block 5 of the calculation is connected. Xhmichesky analyzer 4, unit

Loading and setting 6 quality indicators towmfQ agglomerate. According to the obtained miformacine, block 5 calculates the flow rate of the flow rate of the combiChem shichts. After this, point 5 is connected to the remote control. The integral of the integration is captured at the moment when the output signal reaches the level of the selected reference voltage, i.e. the duration of the integration interval is a variable inversely proportional to the value of the input signal.

In case of a signal mismatch, the control action through regulator 7 goes to metering unit /, and block 5, issuing a command to setter 6f, disconnects from the latter and the system switches to a closed loop: metering unit –– setpoint 5 regulator 7 until the next connection of device 5.

The analog-discrete integrator 9 and UiOK tO for calculating flow coefficients function similarly to elements 2 and 5, with the only difference that elements 9 and 10 do not belong to the main component, but to the other components included in the composition.
