Description

 The invention relates to equipment for thickening hydraulic mixtures and can be used in technological lines for the hydroclassification of granular materials in the mining, chemical industry and in the production of building materials.

 Known thickener slurry, including a hopper with a supply pipe placed with the possibility of vertical movement relative to the hopper thickening chamber, the locking device of the thickening chamber with a stopper and the drive locking device [1].

 A disadvantage of the known technical solution is the design complexity of the slurry thickener and the insufficient efficiency of the device due to the design flaws of the locking device. When opening a conical plug mounted on a conical lever, an uneven release of the dehydrated product occurs and, as a result, water breakthrough often occurs along with the condensed material.

 The aim of the invention is to increase the efficiency of the thickener slurry while simplifying its design.

 This goal is achieved due to the fact that in the thickener slurry, including a hopper with an inlet pipe, a thickening chamber placed with the possibility of vertical movement relative to the hopper, a locking device of the thickening chamber with a stopper and a drive of the locking device, the drive of the locking device is made in the form of a removable and adjustable load and tackle, the ends of the flexible connection of which are connected respectively to the thickening chamber and a removable-adjustable load, and its block is mounted on the hopper, and the hopper is connected by electric a diaphragm with a thickening chamber, the inlet pipe is made with a conical end cover, side windows and fastened to the stopper of the locking device by means of a rigid rod. The removable and adjustable load is made in the form of a tank communicated through locking devices, respectively, with a water main and a drain pipe.

 In Fig.1 shows a General view of the thickener in longitudinal section, in Fig. 2 is a section AA of FIG. 1.

 The slurry thickener includes a hopper 1 with a supply pipe 2 arranged to vertically move a thickening chamber 3 relative to the hopper 1, a locking device of the thickening chamber 3 with a stopper 4, and a locking device actuator. The drive of the locking device is made in the form of a removable-adjustable load 5 and a chain hoist 6, the flexible connection ends 7,8 of which are connected respectively to the condensation chamber 3 and the removable-adjustable load 5, and its block 9 is mounted on the hopper 1. The hopper 1 is connected by means of an elastic diaphragm 10 with a thickening chamber 3, the inlet pipe 2 is made with a conical end cover 11, side windows 12 and, by means of a rigid rod 13, is fastened to the stopper 4 of the locking device. Removable adjustable cargo is made in the form of a container 14, communicated through locking devices 15, 16, respectively, with a water line 17 and a drain pipe 18.

 The device operates as follows.

 Before starting work, the locking device 15 is opened and the container 14 is communicated with the water line 17. The container 14 is filled with water and by means of the chain block 6 is moved to its highest position relative to the hopper 1, and the outer surface of the membrane 10 is concave. The locking device 15 is closed. When the slurry is fed into the hopper 1, particles of solid material under the action of gravity move down through the windows 12 of the inlet pipe, slide along the conical end cover 11 and accumulate in the lower part of the chamber 3 on the bottom 19 and the conical plug 4.

 As the solid condensed product accumulates in the chamber 3, the water is forced up into the hopper 1, and the upper surface of the elastic diaphragm 10 turns out to be horizontal or convex depending on the accumulated product. At this time, the locking device 16 is opened and water is drained from the chamber 14. The mass of the chamber 14 becomes smaller than the chamber 3 with the condensed product, as a result of which the chamber 3 is lowered down, raising a detachable load by means of a chain hoist. At the same time, an annular gap is formed between the bottom 19 and the conical plug 4 and the condensed product expires. The size of this gap, that is, the thickener capacity, is controlled by the amount of water in the chamber 14 by means of locking devices 15 and 16. In case of water breakthrough through the annular gap, close the locking device 16 and open the locking device 15, fill the chamber 14 to the limit, observe the change in the elastic position the diaphragm 10, determine the critical volume of the condensed product with a view to its subsequent release.

 This technical solution will simplify the design by eliminating the drive cylinder and increase the efficiency of the device due to the fact that the deposition of solid particles of material from the hydraulic mixture begins in the hopper 1 and ends directly in the chamber 3. At the same time, the particles of the material flow down under the action of gravity through the windows 12 of the inlet pipe 2, slide along its conical surface and accumulate on the bottom 19 of the chamber 3 and above the conical plug. During this deposition of particles, water is displaced upward due to the difference in their densities, as a result of which water rises to the upper part of the chamber 3 and to the hopper 1. And only when a certain critical volume of solid material is reached in the chamber, it can be displaced downward to form an annular gap between bottom and conical plug, providing a stable release of condensed product. The adjustment of the slit of the release of material and the performance of the thickener as a whole is carried out due to the amount of water in the chamber 14 by means of locking devices 15 and 16.

Thus, this technical solution will allow:
increase the efficiency of the thickener slurry;
simplify its design
