SU1211187A1 - Method of automatic control for cargo flows and loading mechanism of sintering mixture components - Google Patents

Description

The invention relates to the automation of industrial processes, namely the process of feeding and loading bins of the dosing section of sinter plants.

The aim of the invention is to ensure the stability of filling the bins.

The method is carried out as follows.

In the dosing section of the sintering plants there are 2 or more processing lines for preparation with bins for each component. The number of components is 4-6, and the number of bins for each component is 1-6.

The components are fed into the hoppers by means of a loading mechanism that has the ability to move certain (or all) of the components above the hoppers.

The method involves controlling the loading mechanism in the presence of two (or more) paths for preparing.

The components are fed into the dosing compartment by means of a component supply path (a sequence of conveyors and technological mechanisms). Therefore, to feed the component into the bunker, you must do the following:

select the direction of movement of the loading mechanism (forward or backward);

if necessary, switch the material supply path from the first to the other technological line of the current preparation and vice versa;

send the loading mechanism to the desired bunker;

enable component supply path;

submit the desired component by the path;

All of these operations are performed depending on the need to load any bunker of any component.

The need for loading is determined by the pre-selected main priority signs (conditions).

The first main priority attribute ensures that, in the first place, the bins of the component that does not have a load are loaded

material in reserve bunkers, and in workers - the material level is located below the upper working position. This prevents an emergency situation in which both the working and reserve bins of one or another component will be empty.

The second main priority feature ensures the loading of the component, in the reserve bunkers of which there is no material, and the working bins are filled.

The third main priority feature provides the loading of the bins of the component that has one full reserve bunker and the maximum specified

consumption, since the time of emptying the hopper of such a component is the shortest.

In the event that all downloadable components are equal in the three main features, then the sequence of the loaded components is determined by two additional features (conditions).

The first of the additional features gives preference to the loading of the component that arrives at a given point in time along the path of the feed stream, since restructuring the path requires a certain amount

of time.

In the absence of the first additional feature, the loading order is determined by the second additional feature. In which, first of all, the bins of the component from which the signal is received that it is necessary to load from two or more technological lines of preparatory equipment are loaded.

Using the automatic method

controlling the traffic flows and the loading mechanism of the sintering components ensures that the material in the bins of those components that do not have a reserve material is delivered in the first place, the maximum reduction of the loading path idle time in the presence of no material signals in the bins, which contributes to the continuity of the batch compartment.

METHOD OF AUTOMATIC MANAGEMENT OF LOAD FLOWS AND LOADING MECHANISM OF AGROMERATION BATCH COMPONENTS, which consists in controlling the material levels in the bins and the material consumption from them, moving the component supply path from one batch feed line to another and moving the loading mechanism to ensure that stability of filling the bins, first load the working hopper of the component whose backup hopper is empty, and the material in the working hopper is located below top level, then load the material into the backup hopper of the component whose working hopper is full, then load the component whose backup hopper is full and the flow rate from the working hopper is maximum, moreover, if the provisions of the material in the working and reserve hoppers coincide and the material consumption from them for several components, load the g component that is currently flowing along the path, and if there is no material on the path, load the component whose bins are not full for several few charge lines.
