Description

one

This invention relates to the dosing of bulk materials and can be used in powder metallurgy, cement, food and other industries.

A device for dosing is known. neither bulk materials containing a bunker connected by pipelines with receiving tanks. The disadvantage of this device is that it is impossible to form arbitrary doses.

The closest in technical essence and the achieved result to the proposed is a device containing a feeder with a movable discharge funnel for directional feeding of bulk material, measuring tanks and receiving tank 2.

A disadvantage of the known device lies in the lack of accuracy in dosing and inability to form an arbitrary dose.

The purpose of the invention is to improve the accuracy of dosing.

The goal is achieved by the fact that the proposed device is equipped with a measure of the amount of material, a decisive device and a control device, and the cross-sectional area

2

The entrance hatches of the merchants are selected in the form of an increasing row, the merchants have unloading trays equipped with throw-over gates connected with a decisive device connected to the measuring device of the amount of material by the control unit, and the receiving capacitance is associated with each measuring stick.

The drawing shows schematically

10 a device for dispensing bulk materials.

The device contains a funnel 1, the second bulky material 2 enters

15 of the feeder (not shown). From the funnel 1, the bulk material 2 alternately enters the measuring tanks 3, through the hatches 4. The measuring tanks 3 have discharge chutes 5, equipped with throw-over gates 6,

20 The cross-sections of the hatches of the 4 mernik 3 are selected in the form of an increasing row. The measuring tanks 3 through one of the hatches 4 are connected with the receiving tank 7. The cross over gate 6 is electrically connected with

25 by a decisive device 8, which is connected to a material quantity meter 9 and to a control device 10.

Claims (2)

The device works as follows. The amount of material 2 in the funnel l coming from the feeder is measured by the meter 9 of the amount of material, for example, by the radioisotope method, then the funnel 1 is moved uniformly over the measuring tanks 3 and unloading the material 2 into the measuring tanks, 3. In view of the fact that entrance hatches 4 of the meter 3 have cross-sectional areas in the form of an increasing row, the amount of material trapped in them is distributed proportionally to the cross-sectional areas of the entrance hatches. 4. As a result, by appropriately selecting the position of the gates, it is possible to form the dose amount received in the receiving tank 7. The dose value is formed using the resolver 8, based on the data of the material quantity meter 9 and the combo of the control device 10. Thus, high accuracy is ensured. dosing with an arbitrary pre-selected dose. An apparatus for dispensing bulk materials, comprising a feeder with a movable discharge funnel for direct feeding of bulk material, measuring tanks and a receiving container, characterized in that, in order to improve the accuracy of dispensing, a material amount meter, a decision device and a control device are inserted into the device, moreover the cross-sectional areas of the access hatches of the gauges are selected as an increasing row, the gauges have unloading, equipped with throw-over gate valves associated with the resolver, connected to a material amount meter and a control device, the receiving tank being associated with each measuring device.
