Такая установка не может обеспечить откачку загрязненной воды на большую высоту, из-за быстрого износа высоконапорных насосов, хорошо работающих лишь на чистой воде.Such an installation cannot ensure the pumping of contaminated water to a high height, due to the rapid wear of high-pressure pumps that work well only in clean water.

Наиболее близкой к изобретению из известных является шахтная водоотливная установка, включающая насос с всасывающим и напорным трубопроводами, по крайней мере, одну камеру для шлама с подводящим и сливным трубопроводами, задвижки, водосточную канаву и. водосборник [2].Closest to the invention known is a mine drainage plant comprising a pump with suction and pressure pipelines, at least one sludge chamber with supply and drain pipelines, valves, gutter and. catchment basin [2].

Недостатком указанной установки является сложность ее технологической схемы из-за наличия двух насосных at— регатов-шламового и высоконапорного, а также наличия трущихся пар в каме⁵ рах для шлама, что увеличивает износ, установки и уменьшает надежность ее работы.The disadvantage of this installation is the complexity of its technological scheme due to the presence of two pumping at-regattas-slurry and high-pressure, as well as the presence of rubbing pairs in the chamber ⁵ for sludge, which increases wear, installation and reduces the reliability of its operation.

На чертеже изображена установка, '.общий ВИД. ;The drawing shows the installation, '. General view. ;

Шахтная водоотливная установка 15 включает насос 1 с всасывающим 2 и напорным 3 трубопроводами, камеру для шлама, выполненную в виде герметичной емкости 4, установленную ниже днища водосточной канавы 5, ответвления 6 20 и 7 напорного трубопровода 3, концы которых в зоне 8 нижней части емкости 4 направлены навстречу друг другу. В верхней части емкости 4 установлена перегородка 9. которая де~- 25 лит эту часть на приемный 10 и сливной 11 отсеки. В сливном отсеке 11 ' размещены успокоители потока 12, выполненные в виде параллельно установленных пластин, делящих все попереч- ₃₀ное сечение сливного отсека 11 на узкие каналы.Mine drainage plant 15 includes a pump 1 with a suction 2 and pressure 3 pipelines, a sludge chamber made in the form of a sealed container 4, installed below the bottom of the drainage ditch 5, branches 6 20 and 7 of the pressure pipe 3, the ends of which are in the zone 8 of the lower part of the tank 4 are directed towards each other. In the upper part of the tank 4, a partition 9 is installed. Which de ~ - 25 lit. this part to the receiving 10 and drain 11 compartments. The drain compartment 11 'has a flow dampers 12 formed in a parallel set of plates ₃₀ divide all transverse cross sections are a drain compartment 11 into narrow channels.

Чриемный отсек 10 посредством подводящего трубопровода 13 соединен с водосточной канавкой 5 у ее дна, а ₃₅сливной отсек 11 посредством сливного трубопровода 14 гидравлически соединен с водосборником 15· Герметичная емкость 4 имеет люк 16 для ввода коагулянтов. Трубопроводы снабжены ₄θ задвижками 17“21.The suction compartment 10 is connected via a supply pipe 13 to a drain groove 5 at its bottom, and the ₃₅ drain compartment 11 is hydraulically connected to a water collector 15 via a drain pipe 14. The sealed container 4 has a hatch 16 for introducing coagulants. The pipelines are equipped with ₄ θ gate valves 17 “21.

Водоотливная установка работает следующим образом.Drainage installation operates as follows.

Поступающая по канавке 5 загрязнен· Пая вода через подводящий трубопро- ⁴⁵вод 13 подается самотеком в приемный отсек 10. Через люк 16 в емкость 4 вводят коагулянты, например, 2%-ный раствор полиакриламида. Благодаря снижению скорости движения потока ⁵⁰ воды в емкости 4 и вводу коагулянта, из воды выпадают в осадок твердые частицы. Более эффективному осветлению загрязненной воды способствуют также успокоители потока 12, в кото- ⁵⁵рых поток переходит в ламинарный режим движения, что создает хорошие условия, для укрупнения твердых частиц .Entering the groove 5 is contaminated · Soldering water through the inlet pipe ⁴⁵ is fed by gravity to the receiving compartment 10. Through the hatch 16, coagulants, for example, a 2% solution of polyacrylamide, are introduced into the container 4. Due to the decrease in the speed of movement of the flow of water ⁵⁰ in the tank 4 and the introduction of the coagulant, solid particles precipitate from the water. More efficient clarification of contaminated water also contribute to flow dampers 12, ⁵⁵ in koto- ryh flow advances to laminar motion mode, which creates good conditions for the consolidation of solid particles.

и выпадания их в осадок. Осветленная вода по трубопроводу 14 самотеком поступает в водосборник 15· При поступлении в водосборник осветленной воды насос 1 может быть включен на откачку на поверхность осветленной воды, при этом задвижки 18 и 19 должны быть закрыты. В случае выключения насоса 1 закрывается задвижка 17. После того, как в емкости 4 накопится достаточное количество шлама, перекрывают задвижки 20 и 21, герметично закрывают люк 1б, открывают задвижки 18 и 19 (задвижка 17 закрыта) и включают насос 1. В этом случае происходит разгрузка емкости 4 от шлама восходящим потоком воды, которая поступает от насоса 1 по ответвлению 7 в нижнюю часть емкости 4, увлекает с собой шлам и по ответвлению 6, подает его в напорный трубопровод з, при этом для лучшей разгрузки шлама трубопровод 7 имеет в емкости 4 дополнительное ответвление 22 для подачи части воды в верхнюю часть емкости 4. После выгрузки шлама задвижки 18 и 19 перекрывают, открывают задвижки 20 и 21 и люк 16, и возобновляют процесс накопления шлама в емкости 4. При большом количестве поступающего по канаве 5 шлама может быть установлено две или три емкости .and their precipitation. The clarified water through a pipe 14 by gravity enters the catchment 15. When clarified water enters the catchment, pump 1 can be switched on to pump clarified water to the surface, while the valves 18 and 19 must be closed. In the case of turning off the pump 1, the valve 17 closes. After a sufficient amount of sludge has accumulated in the tank 4, the valves 20 and 21 are closed, the hatch 1b is sealed, the valves 18 and 19 are opened (the valve 17 is closed) and pump 1 is turned on. In this case there is an unloading of the tank 4 from the sludge with an upward flow of water, which flows from the pump 1 through the branch 7 to the lower part of the tank 4, carries the sludge with it and along the branch 6, feeds it into the pressure pipe 3, while for better discharge of the sludge, the pipe 7 has capacity 4 optional a branch 22 for supplying part of the water to the upper part of the tank 4. After unloading the sludge, the valves 18 and 19 are closed, the valves 20 and 21 and the hatch 16 are opened, and the process of accumulating sludge in the tank 4 is resumed. With a large amount of sludge coming through the ditch 5, it can be installed two or three containers.

с возможностью их попеременной работы. В этом случае один сосуд может работать по накоплению шлама, другой в это время разгружаться, а третий может находиться в резерве.with the possibility of alternating work. In this case, one vessel can work on the accumulation of sludge, the other is unloaded at this time, and the third can be in reserve.

Данная водоотливная установка позволяет упростить конструкцию оборудования для водоотлива, исключить откачку высоконапорным насосом загрязненной воды, сократить заиливание и чистоту водосборников, уменьшить объем горных работ по сооружению водосборников, повысить ресурс и надежность работы насоса.This drainage installation allows to simplify the design of equipment for drainage, to eliminate the pumping of contaminated water by a high-pressure pump, to reduce siltation and cleanliness of water collectors, to reduce the amount of mining work on the construction of water collectors, and to increase the service life and reliability of the pump.
