Известен гидротурбоциклон, включающий цилиндроконический корпус с тангенциальным входным патрубком, патруб ками отвода сгущенной фракции и очищенной жидкости, вал, установленный соосно внутри корпуса с укрепленным: на нем с возможностью вращени цилиндрическим фильтрующим элементом l . A hydroturbine cyclone is known, including a cylindrical body with a tangential inlet, branch pipes for discharging the thickened fraction and purified liquid, a shaft mounted coaxially inside the body with a fixed: rotatably cylindrical filter element l.

Недостатком такого гидротурбоциклона вл етс мала эффективность разделени , обусловленна тем, что в нем не достигаетс качественный отбор осг ветленной фракции.The disadvantage of such a hydro-turbo cyclone is the low separation efficiency, due to the fact that it does not achieve a high-quality selection of osg vegetative fraction.

Это устройство вл етс наиболее близким по технической сущности и достигаемому результату.This device is the closest to the technical essence and the achieved result.

Однако такой гидротурбоциклон отличаетс малой эффективностью разделени .However, such a hydro-turbo cyclone is distinguished by a low separation efficiency.

Целью насто щего изобретени вл етс повышение эффективности разделени .The purpose of the present invention is to increase the separation efficiency.

Поставленна цель достигаетс тем, что полый цилиндрический фильтрующий элемент в нижнем торце снабжен герметичной крышкой, а в верхнем открытом его торце неподвижно укреплены радиальные ст жки, выполненные в виде лопастей гребного винта.The goal is achieved by the fact that the hollow cylindrical filtering element in the lower end is provided with a hermetic cover, and in the upper open end of it its radial stubs are fixed, made in the form of propeller blades.

Claims

The hydro-turbo-cyclone consists of a cylindrical body 1 with a lid 2 in which the outlet pipe of the purified liquid 3 is strengthened, and an electric motor 4 is placed on it. The cylindro-conical case 1 is equipped with a tangential inlet 5 and a branch pipe of the thickened fraction 6. The branch pipe of the purified liquid is welded a plug 7, in which the upper bearing 8 of the shaft 9 is mounted. The second shaft support 9 is made as separate radially mounted stationary sliding bars 10. At the lower end of the shaft 9, the reinforcement plates 11 are fastened, and A closed bottom frame 12 is installed on a ribbed frame 13, which serves as the basis for the filter element 14. A sealing ring 15 is fastened on the frame 13 and inserted into the end of the nozzle for cleaning the cleaned liquid 3. At the upper end of the shaft 9, the driven pulley 16 is kinematically connected with a belt to the driver a pulley 17 mounted on the shaft of the electric motor 4. A discharge pipe 18 is connected to the nozzle for discharging the purified liquid. The hydroturbine cyclone operates as follows. The drilling fluid to be cleaned from the wells through the tangential inlet 5 enters the internal cavity of the cylindrical body 1 and fills it. The motor 4 is turned on and the shaft 9 begins to rotate. Together with the shaft 9, the blades 11 and the filter element 14 rotate. The blades 11 twist the drilling solution, as a result of which heavy mechanical impurities are thrown by centrifugal forces against the wall of the barrel-conical body 1 and they begin to fall down through the calibrated branch pipe of the thickened fraction h are removed from the hydr orturbocyclone. The filtered particles of mechanical impurities remaining on the outer wall of the filtering element 14 are also thrown by centrifugal forces to the inner wall of the cylindrical body 1 and removed from the hydroturbocyclone. The cleaned drilling fluid from the inner cavity of the filter element 14 passes through the gaps between the radial liners 10 and enters the branch pipe of the cleaned liquid 3 / a from it through the discharge pipe 18 for its intended purpose. By making the radial strut 10 in the form of blades of the rowing screw in the cavity of the rotating filter element 14, conditions are created that facilitate the spinning flow of the purified liquid into the discharge nozzle 3. This is how the hydroturboclone works at the inlet to it cannot or effectively create pressure that would provide the necessary speed of rotation of the fluid. If the inlet pressure is large enough and. provides the necessary speed of rotation of the fluid in the housing 1 hydroturbation, the latter operates without forcing the filter element 14. In this case, the kinematic connection between the shaft of the electric motor 4 and the shaft 9 of the filter element 14 is absent. The shaft 9 of the filter element 14 is rotated by a fluid flow using blades 11, which operate in the mode of a turbine wheel. Thus, by supplying the hollow cylindrical filter element with a hermetically sealed lower end, stationary reinforcement in the open end of the radial strut made in the form of propeller blades, as well as by supplying the hydroturbocyclone with an additional drive of forced rotation, the shaft of which is kinematically connected to the filter shaft element, high separation efficiency is achieved. Claim 1. Hydro-turbo cyclone comprising a cylindrical body with a tangential inlet nozzle, branch pipes for discharging a condensed fraction and a purified liquid, a shaft mounted coaxially inside the body on the supports and radial straps with blades fixed to it with rotation and a hollow cylindrical filter element characterized by that, in order to increase the separation efficiency, the hollow cylindrical filtering element is provided with a hermetic lid in the lower end, and still in its upper open end radial strut reinforced in the form of propeller blades. 2. A hydroturbine cyclone according to claim 1, characterized in that it is provided with an additional forced rotation drive, the shaft of which is kinematically connected to the shaft of the filter element.
