(54) DEVICE FOR MEASURING THE VELOCITY OF DEPOSITION BY A SOLID COMPONENT OF A GROUND MASS

one

The invention relates to a measurement and control technique, is intended to investigate sedimentation processes, and can be found in all areas of the industry where suspensions are used.

A device for measuring the solids content in a pulp is known, which contains a vessel for pulp and three and three carefully insulated electrodes, which are picoBo by height of the vessel and connected to a bridge circuit. The principle of operation of the device is based on measuring the electrical resistance of the pulp during the deposition process.

A disadvantage of this device is the low accuracy of measurements when studying the processes of sedimentation in the mudflow mass, which is caused by the nonlinear dependence of the magnitude of the electro-electrochemical effect on the pulp concentration.

A photovoltaic device for studying iq) oeccoB of solid phase deposition in a liquid is known, containing

optical system with illuminator in photographic receiver, placed on the sides of the cuvette with the liquid under study, into a recorder connected to the output of the ph | reference number G 2 T.

The disadvantage of this device is the low sensitivity of the measurement, scientific research institutes, due to the high density of the mudflow.

20 the change in time, of the head of the center of the mass of the mixture in the cylinder, i.e., continuously measure the speed; sedimentation rate. 396 The purpose of the invention is to improve the measurement accuracy by continuously measuring the wrist; coordinates of the center of gravity of the mixture volume. The goal is achieved by the fact that a device for measuring cKqpocTH deposition of a solid component of mudflow, containing a cylinder for loading the mixture under study, measuring and recording units, additionally contains two mutually perpendicular tactile systems equipped with blocks that maintain the amplitude of their own oscillations The cylinder of which is the cylinder. To simplify the measurement process, the cylinder is connected to the counterweight. The drawing shows the proposed device, the General view,. The device consists of a cylinder 1, a mudslide mass is loaded into it, equipped with semi-axes 2 and 2, their bearing is fixed on frame 3, which has two semi-axes 4 and 4, rotating in bearing parts 5 and 5. Half-axle 2 is connected with a block for maintaining own oscillations (to extracting the first swing system 6, and half-4) with a block for supporting natural oscillations of the second swing system 7. when it oscillates relative to axis 2-2, the period of oscillation of such a model (with small amplitudes of oscillations) can be found from the expression where O is the distance from the axis of oscillations to the center of gravity; yn is the mass of the monitor; signtle axis axis l is the acceleration of gravity, then the equation for determining a can be written in the form.The moment of inertia e to find a must have the value of the moment of inertia of the mudflow mass, therefore 3z-D + and For the moment of inertia of the second system itself (with an empty cylinder) Ul (is the moment of inertia of the first system itself. 6 DQ is determined using the second system, about the cylinder 1, frame 3, semi-axes 4, representing an elastic rod One end of which is rigidly fixed and the other connected to the frame 3; axis 4, connected to block 7, supporting the natural oscillations of the second pendulum system CT. where C is a constant rod 4. To simplify the process, a measured cylinder is connected with a counterweight 8. The device operates as follows. The cylinder with the mudflow mass under the action of the excitation unit oscillates simultaneously in two mutually perpendicular partial systems. According to the values of the oscillation period of the second tiling system from the above extrusion, a continuous series of Ea values is determined. - the moment of inertia of this system. According to the values of T (the period of oscillations of the first pendulum system) O is determined - the distance from the axes of oscillations to the center of gravity of the mudflow volume. As a result, we obtain a continuous series of values of the vertical coordinate of the center of gravity of the mudflow volume in BpeMGHijt, i.e. deposition rate. Claim 1.
