Description

The invention relates to devices for the rotor of hydromechanical processes for the separation of high viscosity suspensions and can be used in the chemical, petrochemical, coal, energy industries and a number of other industries.

The purpose of the invention is to increase the efficiency of the separation.

FIG. 1 shows a device for the separation of highly viscous suspensions, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 - node I nd FIG. one; in fig. 5 shows section B - B in FIG. one.

A device for separating high viscosity suspensions includes a cylindrical body 1 with a tangential inlet nozzle 2, a drain nozzle 3 and a sand nozzle 4 installed in the apex of the conical part of the body 1, a shirt 5 with a nozzle 6 supplying heat transfer fluid installed coaxially with the drain nozzle 3. V The housing is concentric with the drain nozzle 3; a cup 7 is installed, on the side surface of which tangential windows 8 are made, while the lower part of the drain nozzle 3 is fixed in the bottom 9 of the cup 7. 5 with a gap of 10 with its bottom 11, a vertical partition 12 is installed, dividing the cavity of the jacket 5 onto the descending channel 13 and ascending channel 14, while the cavity of the jacket 5 is connected to the cavity of the cup 7.

A tangential inlet nozzle 2 has an inlet nozzle 15 for feeding a highly viscous slurry, a nozzle 16 for supplying the reagent, and a mixer 17 with a screw thread 18 on its inner surface. The inner surface 19 of the cylindrical part of housing I can be made ribbed.

A device for the separation of high viscosity suspensions is as follows.

The initial high viscosity suspension under high pressure through the pipe 15

steps into the mixer 17, where a reagent having a low temperature is also supplied (under low pressure m.) through the pipe 16. In the mixer 17, due to the presence in it of a screw thread 18 of the initial high viscosity suspension and the reagent is displaced and twisted, this enriches the initial suspension with the necessary components and increases its fluidity.

Then, through the tangential nozzle 2, the mixture enters the cylindrical housing 1. Simultaneously, through the nozzle 6 into the cavity of the present channel 13 of the jacket 5, a heat carrier is supplied, which is also a reagent. Pass through the gap 10 between the bottom 11

scab 5 and a vertical partition 12; the coolant rises along the ascending channel 14, enters the cavity of the glass 7 and then through the tangential windows 8 enters the housing 1. The tangential windows 8 are made in the direction of rotation of the flow of the separable mixture, which ensures the introduction of the heat carrier into the flow with rotation directed to side, as the suspension flow, and simultaneously interferes with its penetration into the cavity of the glass 7. Thus

Thus, the coolant is heated not only by the wall layer of the suspension, but also by its central layers adjacent to the outer surface of the glass 7. At the same time, the rotation speed of the suspension does not decrease. In the cavity of the housing 1, under the action of centrifugal forces, mechanical impurities are released from the heated suspension, which are discharged from the apparatus through the nozzle 4. The cleaned suspension, enriched with reagent, is withdrawn by an upward flow through the drain nozzle 3 for further processing. The suspension coming out of the drain pipe 3 does not lose its flow properties due to the heating of the drain pipe by the heat carrier supplied to the pipe 6.

Thus, due to the tangential introduction of the heat transfer medium into the device cavity, the hydrodynamics of the separable suspension flow improves due to its all-round heating, which reduces the viscosity

suspension, which increases the efficiency of its separation.
