The invention relates to the precipitation of solid particles from a liquid, namely, the settling and purification of industrial and wastewater, and can be used in the technique of mineral processing and other forms of processing suspensions.

The aim of the invention is to increase the productivity and the degree of clarification of the suspension by eliminating the roiling of the flowing sediment in a counter-flow of liquid.

 FIG. 1 shows a liquid clarification device, longitudinal section; FIG. 2 - node I. in FIG. one; in fig. 3 is a view of L in FIG. one.

The device includes a housing 1, a drainage chute 2 provided with a nozzle 3 for removing clarified water from the apparatus, a distribution manifold 4 with a nozzle 5 for supplying the initial liquid, a sludge hopper 6, in the lower part of which there is an unloading nozzle 7 with a valve 8, and the upper part contains an inclined a baffle 9 formed with rectangular nozzles 10 for discharging sediment and containing slit-like holes 11. I

A package of parallel plates 12 and a grid 13 fixed above them are installed in the housing 1, made in the form of horizontal, movably fixed flaps forming the drainage channels 14 adjacent to the upper parts of the rectangular nozzles 10.

The device works as follows.

The source fluid through the pipe 5 is fed into the distribution manifold 4 and, spreading in all directions, rushes into the space between the rectangular pipes Yu above the inclined partition 9, and then enters the package parallel to the plates 12. Lift up from the bottom upwards through the interplate space 15, the fluid is gradually cleared of suspension and then, reaching the upper edges of the plates 12, overflows into the chute 2 and is removed from the apparatus through the discharge nozzle 3. The movement of the fluid along the interfacial space 15 is accompanied by otsessami its breaking. Hard

the suspended particles penetrate through the grate 13 and fall onto the plates 12. The seeding material, under the action of gravity forces, slides along the dislocation

channels 14 through rectangular nozzles 10 into the sludge hopper 6, from which periodically the hydrostatic pressure of the liquid column is removed through the discharge

nozzle 8. Depending on the desired mode of operation of the apparatus, due to the composition of the pulp, and the required flow rate of the clarified liquid in the inter-plate space 15, the angle of inclination of the plate flaps of the grate 13 is controlled relative to the working surface of the plate 12. This makes it possible to provide

a significant influence on the kinetics of the process of sedimentation of solid particles and, thus, to change the device performance and the degree of water purification within fairly wide limits. Can

To achieve such an arrangement of the lattice flaps 13 in the interplate space 15, in which most of the sediment falls out directly onto the lattice plates.

The precipitation due to more

the steep arrangement of the valves, as compared with the plates 12, is rapidly compacted and rolls down through the gaps between the doors into the drain valve 14.

At the same time, due to the shortening of the path of the settled particles, the deposition time is reduced. In addition, the location of the lattice at the interface allows one to exclude mutual

the influence of the flow of liquid and sediment sliding down from the plates 12, which makes it possible to prevent vzmuchivanie and liquefaction settled sludge. The leaves of the grille 13 can also be directly

influence on the processes of deposition, played the role of mechanical particles chippers, perelyusimymi adjacent to the valves of the micro-flows of the liquid. During repair and maintenance work, when it is necessary to flush the apparatus, you can turn the flushing water flows by turning the lattice flaps at a certain angle.

directly onto the plates 12 and clean them of sediment. Openings of the collectors of the RL 4 serve as holes 11.
