    This goal is achieved in that a plant for dewatering granulated slag, containing a bath with waste, 5 wheels in it with perforated buckets and gutters, as well as a receiving conveyor, is equipped with a thickener connected to the drain chutes.
    The thickener is embodied as concentric containers; an outer one, with a circumferential drainage chute located in its upper part, and a funnel in the lower part, and an inner one connected to the inlet pipe, the latter being tangentially connected to the inner tank. In addition, the thickener is provided with radial drain chutes located between the inner tank and the circumferential drain chute, and the installation is equipped with a pressure pump and adjacent to the perforated buckets of the wheel with a loading device, the latter is connected to the drainer funnel through the pressure pump. branch pipe with condensate funnel outlet. 4g, 1 shows a diagram of a plant for the dewatering of granulated slag; in fig. 2 - thickener, Kid over the top. The plant for dewatering granulated slag contains a wheel 1 with an axis 2 and a thickener 3. The wheel is located in the bath 4, over which pitaccty 5 is installed for a mixture of granulate and water. The wheel 4 is made with perforated buckets 6. The installation is also equipped with a funnel 7 and a receiving conveyor 8 installed under it 8. On both longitudinal sides of the bath 4 are located drains with a KnoHHbnvi bottom io connected to the pressure pump 11 and a collector 12 through the bottom bottom point 10 of the mouthpiece 13 and the drain pipe 14, and the discharge pump 11 is connected by a pipe 15 to the thickener 3. Instead of the discharge pump 11, you can use a sloping connecting pipe. water 15 .. The thickener 3 is made in the form of concentric tanks: a shirk shirkuyu outer 16 with a circumferential drain chute 17 and a funnel 18, which through. The drain and discharge pipe 19 is connected to the injection pump 2O and the internal 21 with a tangential inlet pipe 22 and an outlet at its lower end 23 for a bath 4 of the mixture of water and solids pumped from the drain chute 9. Metsdu internal capacity of 21 and a circumferential drain chute 17 thick thickness 3 located radial drain gutters 24 - 26, which are connected with a sash gland 17. Gutters have drain edges 27 and 28. Circumferent drain chute 17 out; chen with drain edge 29, outflow funnel ZO and a discharge pipe 31. A pressure pump 20 via a connecting pipe 32 communicates with a charging device formed by the nozzle 33, which is located above the perforated buckets 6 for the slag 34 of wheel 1. A bypass valve 35 is connected to the pump 20 An alternate pipe 36, the outlet of which is located above the internal tank 21 of the thickener 3. The pipeline 32 also has a shut-off valve 37. In another embodiment of the installation, there is no need to remove the pipe 19 of the funnel 18 of the thickener 3, the injection pump 2O and the connecting pipe 32 with the nozzle 33 through the wheel 1, as well as in the branch pipe 2 from the connecting pipe 2 into the internal tank 21 of the thickener 3 bypass line 36, while the outflow of the funnel 18 of the thickener 3 is connected to the settling tank 39 via the discharge pipe 38. On an 18, two caps 4O and 41 are arranged coaxially one above the other in the form of inverted cones with traction devices 42 and 43. Pipeline 44 is connected to chamber 45 under a smaller cap 4O, and pipe 46 to chamber 47 between caps 40 and 41. Pipelines 44 and 46 are equipped with valves 48 and 49, respectively, and are connected by means of a pump 5O and a common pipe 51 to the upper part of the outer tank 16 of the thickener 3. The installation works as follows. Rotating wheel 1 by means of perforated buckets 6 selects from the bath 4 a mixture of slag and water and approximately a half-turn feeds the pork into BqpOHKy 7, and water flows out of the perforated buckets 6 into the bath 4, From BqpoHKH 7 the slag is fed to the receiving conveyor 8. B installed on both The longitudinal sides of the bath 4 gutters 9 with a sloping bottom 10 flow down water contaminated with solids. The injection pump 11 transports the mixture of water and solids through the mouthpiece 13, located at the bottom of the bottom 1O of the groove, the mouthpiece 13, the waste pipe 14 and the connecting pipe 5, the wire 15 to the thickener 3. The mixture of water and solids from the groove 9 of the wheel 1 to the thickener 3 can also be transported through an inclined connecting pipe. A mixture of water and solid matter is pumped out of the drain chutes 9 of scaffold 1 by means of an injection pump 11 through a pipe 22 of the internal capacity 21 to the pipeline. The contaminated water flows through the upper part of the internal container 21 of the spiral flow, which before reaching the lower end of the water 23 inner tank is calmed down. At the lower end 23 of the inner tank 21, the water rises upward into the outer sviKoerb 16 and through the radial troughs 25, which, with their drain edges 27 and 28, cover the entire surface of the thickener 3, as well as along the circumferential trough chute 17 with the drain edge 23 through the outlet funnel 30 through the discharge pipe 31 flows into a collector (not shown in the drawings) for reuse. The water velocity in the outer tank 16 of the thickener 3 can be adjusted in accordance with the sedimentation rate of solids so that there is only a minimal amount of fine particles in the water that flows from the condensate bodies 3. The amount of solid particles in the exposed water drawn from thickener 3 can be determined by measuring the free cross section between the outer tank 16 and the inner tank 21. The injection pump 20 overmines the concentrated mixture of water and solids through connecting pipe 32, for example formed by the nozzle 33 boot device. Transported in the perforated wheel covers 6, 1 slut 34 forms a filter for a concentrated mixture of water and solids injected through the co 33 to separate the solids. When the wheel 1 is stopped, the middle pipe 32 is closed by means of the shut-off member 37 and the pump 20 transports the concentrated water and solid water deposited in the thickener 18 of the thickener 3 through the bypass pipe 36, which is closed by means of the valve 35, during operation of the wheel 1, thickener. Thus, in the funnel 18, only small amounts of solids are precipitated and the mixture remains passable. The performance of pump 2O forms part of the mixture quantity supplied to the thickener 3, by feeding the amount of the concentrated mixture of water and solids fed to the loading nozzle 33 through the wheel 1, can be adjusted by changing the number of revolutions of the pump 20. When executing the installation without the outlet pipe 19 of the thickener funnel 18. 3 water flows through. discharge pipe 38 and sump 39. In order to prevent solid particles from settling down at the lower end of the funnel 18 and not blocking the pipeline 19 when they are put into operation, two hoods 40 and 41 are arranged coaxially above the core in the funnel 18 The cones, which are separately lowered and raised above the traction devices 42 and 43, When the unit is started up, which only works when necessary, the upper, larger cap 41 is raised. In this position, it is maintained by introducing water through the valve 49 and the pipe 46 into the chamber 47 between the two caps 40 and 41 under pressure, which is hydrostatic in the thickener 3, The solid (and the lacquer) located above the cap 41 enters the intermediate chamber 47 In this case, the lower smaller cap 40 is vented through a small slit, the valve 49 is closed, and the slide 48 of the pipeline 44 entering under the smaller cap 4O of the pipeline 44 is unlocked. The mixture of water and solid matter is transported by the funnel 18. The top cap 41 is closed again and remains closed during the whole subsequent working station. The installation described provides good dehydration of the granular bulk material while achieving good water quality for later use. The dp dehydration installation of granulated slag is characterized by its simplicity of construction and low cost of its manufacture, high reliability in operation, as well as small dimensions.
