(54) DEVICE FOR AUTOMATIC DISTRIBUTION OF BULK MATERIALS BY APPARATUS

I

The invention relates to devices that distribute bulk material supplied by belt conveyors to apparatuses, and can be used in the chemical, construction and other industrial fields.

A device for automatically distributing bulk materials into apparatuses is known, comprising an accumulator of the number of operating apparatuses connected to one of the inputs of the multiplication unit, to another input of which conveyor performance sensors are connected, and the transducer is connected to the regulating units of the apparatus automatic feeding unit. In addition, the device comprises an intermediate hopper with a metering device connected to a belt conveyor, a material level sensor in the intermediate hopper 1.

However, in this device, the uniform distribution of material across the apparatuses depends on the accuracy of determining the level of the material in the latter, the last bunker, and therefore the apparatuses are not loaded stably.

The purpose of the invention is to increase the stabilization of the loading apparatus.

The goal is achieved by the fact that, in a device for the automatic distribution of bulk materials into apparatuses, comprising a correction regulator, the output of which is associated with power supply settings of apparatuses, each of which has plows, a bunker with level sensors and a dispenser, an actuator associated with plows and ratio block, intermediate hopper with dosing unit connected to the belt conveyor, sensor output

The material level in the intermediate bunker is connected to a correction regulator and a return conveyor belt is inserted from the conveyors loading the power settings into the intermediate bunker.

FIG. 1 shows a functional diagram of the device; in fig. 2 is a diagram of the installation of power devices.

Claims (1)

The device contains belt conveyors 1 associated with units 2 for supplying apparatuses, an intermediate hopper 3 with a dispenser 4 connected to a belt conveyor 5, a material level sensor 6 in the intermediate bunker 3, the output of which is connected to the input of the correction regulator 7, and the output The latter is connected to installations 2 of the power supply of the apparatus. Under the ends of the belt conveyors 1 there is an initial section of the return conveyor 8 into the intermediate hopper 3. Each unit 2 power supply apparatus has plows 9, which discharge material from the conveyors 1 into the bunker 10, equipped with a level sensor 11, the output of which, as well as the output of the master unit 12 connected to the input of the regulator 13 level. The output of the regulator 13 through the actuator 14 is connected to the plows 9. A hopper 10 is connected to a dispenser 15, which is connected via a weight sensor 16 to one of the inputs of the capacity regulator 17, to the output of which the output of the ratio unit 18 is connected, the input of which is connected with the output of the correction regulator 7. The device operates as follows. The material is conveyed by belt conveyors 1 into the hoppers 10 of the power supply units 2 of the devices. In the section of the tape before the installations 2 of the power supply of the apparatuses, the dispenser 4 and the belt conveyor 5 feed the material from the intermediate hopper 3 in an amount which is known to be greater than the difference between the average and minimum input of the material, i.e. in the area of the belt conveyors 1 from the point of entry of the material to the intermediate hopper 3 there is a quantity of material which is known to be greater than the average value. The level regulator 13 controls the plows 9 through the actuator 14 by signals from the level sensor 11 and the driver unit 12 so that the level of the material in the bunker 10 of the power supply 2 is within the specified limits. Excess material enters the next installation of the power unit 2. After the last installation of the power supply of the device, the return conveyor belt 8 is fed into the intermediate hopper 3. The capacity controller 17 according to the signals from the ratio block 18 and the weight sensor 16 controls the capacity of the hopper 15 dispenser 10. If the average capacity of the machines power supply 2 is not long will be equal to the average value of the material intake, this will lead to a change in the level of the material in the intermediate bunker 3. In this case, the sensor 6 of the level of the intermediate bunker 3 generates a signal to a correction regulator 7, which, through ratio block 18 and regulator 17, changes the performance of the power settings 2. The use of the proposed device allows ensuring stable loading of devices. Apparatus of the Invention A device for the automatic distribution of bulk materials into apparatuses, comprising a correction regulator, the output of which is associated with power supply settings of apparatuses, each of which has plows, a bunner with a level sensor and a dispenser, an actuator associated with the plows, and a ratio block, An intermediate hopper with a metering device associated with the TpaHcnoptepOM tape is distinguished by the fact that, in order to increase the stabilization of the loading of the apparatus, the output of the material level sensor in the intermediate bunker is connected to a corrector to the adjusting controller, and a material return conveyor belt was introduced from the conveyors loading the power settings into the intermediate hopper.
