Description

The invention relates to the compilation of multicomponent mixtures of a given composition and can be used in metallurgical, chemical, construction and other industries.

According to the main author. St. No. 548503 known path supply and compilation of the charge, including a hopper with a feeder. ₀ for each component of the charge, raspolo- ^υ adjoint underneath component feed conveyor Vesoizmeritel load on it, material flow divider at the end of feed conveyor, each conveyor circulars insulating component 15 is the beginning of which is located below one _g IEs flow divider outputs, and the end is above the feed conveyor of the component in front of the load meter, under the other output of the material flow divider 20 is a component meter, while the meter ovleny before loading the common node at the same distance from it [1].

In the known device, due to the fact that the load capacity meters of the components (charges have certain and considerable dimensions, it is structurally difficult to place these load meters 3 over the common overload unit when compiling multicomponent batch materials. transport lag in the dosage of the components of the mixture, worsening the quality of the mixture during its preparation. ”In addition, the preparation of a multicomponent mixture is required radial location of components dosing paths relative to the total charge node overload, which entails constructive complication paths supplying charge components from the warehouse to the total raw bridle overload.

The purpose of the invention is to improve the quality of the charge and simplify the design., The goal is achieved in that the device is additionally equipped with a conveyor for supplying each component with a certain speed to the common conveyor, the beginning of which is located under the load cell of the component’s productivity, and the end of the nat is a common conveyor.

The speeds of these conveyors are set so that the transport time for the delay from the weight meter of the productivity of each component to the common point of their meeting on the common conveyor is the same. Different speeds of conveyors for feeding the charge components to a common conveyor eliminate the time of transport delay at. dosing of the components of the mixture, which improves the quality and stabilizes the composition of the latter. The proposed supply and preparation path of the charge allows jq to constructively simply arrange the dosage paths of the charge components relative to the general conveyor, • “One hundred provides the most rational technological scheme for supplying components from the raw materials warehouse.

The drawing shows a functional block diagram of the path of supply and compilation of the charge.

The feed and charge preparation paths comprises a hopper 1 with a feeder for each 20 component, under which a conveyor 2 for feeding the component with a load meter 3 is located. At the end of the component delivery path, a material flow divider 4 is installed (for example, a funnel with a gate), one outlet of which is located under the start of the circulation conveyor 5, and the other above the component weight meter 6. The end of the circulation- -jq of which conveyor is located above the component supply path in front of the load meter 3. Conveyors 7 are supplied under the weight measuring instruments for the performance of the components, components for a common conveyor 8 having different speeds.

The device operates as follows.

Each component of the charge by the hopper feeder is fed to the feed conveyor 2, 40, at the end of which the component is divided into two parts by the divider 4! one part of the circulation conveyor is returned to the feed conveyor 2 in front of the load meter 3 nag. 45 rueki, and the other, through a productivity meter 6 and conveyor 7, enters the general conveyor 8, which feeds the charge into the sintering department of the sinter plant. The predetermined productivity of each component is controlled by a weight meter 6, and is supported by the control of a material flow divider 4. The load on the load meter 3 is maintained constant and greater, for example, by 10% of the maximum required, controlling the hopper feeder 1.

At a constant speed (V) of movement of the common conveyor 8, the time of transport delay of each component to the common point · (point N) of their meeting on the common conveyor 8 is determined from the expressions: - for the first component, + t _x - for the second component, etc. where 't' - b- | . 2- 4- L 1 y ^?

In order for the transport delay time from the weight meter of the productivity of each component to the common point of their meeting (point N) to be the same, it is necessary that the relations between the conveyor speeds are determined by the expression at V = const; V-i = const taking into account (1) = const

(54) THE TRACT OF FEEDING AND MAKING A DEPTH DYNAMENT from the weighing instruments for the performance of each component to the common point of their meeting on the common conveyor was the same. Different speeds of conveyors for supplying charge components to a common conveyor eliminate transport lag time when dispensing charge components, which improves the quality and stabilizes the composition of the latter. The proposed path for supplying and compiling the charge makes it possible to simply position the paths for dosing the charge components relative to a common conveyor. This provides the most rational flow chart for the supply of components from the raw material warehouse. The drawing shows a functional block diagram of the supply path and the composition of the charge. The supply and charge path for the charge contains a hopper 1 with a feeder of each component / under which the conveyor 2 of the component is supplied with a weight gauge 3 loads. At the end of the component's delivery path, a material flow divider 4 is installed (for example, a funnel with a gate), one outlet of which is located under the start of the circulation conveyor 5 and the other over the weight measuring device 6 of the component's performance. The end of the circulation conveyor is located above the component supply path in front of the load balancer 3. Under the weighing instruments of the component performance, the conveyors 7 supply the components to the Common conveyor 8, which have different speeds, are installed. The device works as follows. Each component of the charge is fed by the feeder of the hopper to the conveyor 2 at the dacha, at the end of which the component divider 4 is divided into two parts; It enters the common conveyor 8, which supplies the charge to the sintering department of the sinter plant. The target performance of each component is monitored by the weighing device b, and it is maintained by controlling the flow of material 4. The load on the weight meter 3 is supported at this and the most, for example, by 10% of the maximum required load at the hopper 1. At a constant speed (V) of movement of the common conveyor 8, the transport lag time of each component to the common POINT (point N) they meet on a common pipeline 8 is determined from the expressions: -f + - (- for the first component, f + t - for the second component, etc., where tS-t l, 5i 4.
