Description

I

The invention relates to the determination of the physicomechanical properties of dispersed materials.

 A device for determining the flowability of dispersed materials is known, which contains containers with openings and internal 1.

The disadvantage of this device is VL-with the inability to determine the flowability in complex power noise and a small range of studies.

It is also known a device for determining the flowability of materials, containing containers with combined holes, a device for their rotation and a recorder C.

However, the device cannot determine the material flowability in complex force fields, which actually occur in production, where both gravitational and centrifugal forces affect the material.

The purpose of the invention is to provide express determination.

The goal is achieved by the fact that the device is made in the form of two containers interconnected by a tube and placed on a rotating disk with the possibility of changing the direction of the axis of rotation in space. In addition, the containers are configured to move across the disk in the radial direction.

The drawing shows the device, General view, cut.

The device consists of a housing 1 installed in the frame 2 by means of the axles 3, an electric motor 4, a shaft 5 installed in sub-supports 6 in the frame.

A disk 7, on which two vessels 8 and 9 with holes are installed, an electromagnet 10 with a damper 11 located in the tube 12, is mounted on shaft 5 and connects both vessels.

The tubes connecting the vessels are interchangeable with different diameters of the outlet. A light bulb 13 and a photodiode 14 are mounted on the tube 12.

On the diametrically opposite side of the disk, the counterweight 15 is fixed. On the shaft, there are mounted current-earth rings 16, on the case 1 - current collectors 17.

The device works as follows:

at once.

Dispersed material of a strictly defined mass is poured into the vessel 8 and the vessel is fixed on the disk 7. The device body i is set to the required position relative to the horizon by turning it in the axis x 3 relative to the bed 2. Then the engine 4 is turned on and the disk 7 rotates. 8 n 9 vessels on it. When a specified number of esters is reached, through the current collectors 17, a signal is sent to the electromagnet 1O, which opens the outward opening of the vessel 8 with a valve 11. The material is under the influence of centrifugal and gravitational forces ionic attraction peresypaets into the vessel 9. The flow of material overlaps the light flux from the light bulb 13 to the photodiode 14 through the n last relay includes elektrosekundomer (not shown).

After the material has elapsed, the electric second stops and the drive motor shuts off.

Vessel 8 is removed and the remainder of the material is weighed. By the difference of the buried material and its remainder, the amount of material elapsed during the time recorded on the electrosecond meter is judged. According to these two values, the flowability of dispersed material is judged under a certain effect on it of centrifugal forces and their combination with gravitational forces.
