(54) GUIDE TO MOTHER RBO11 AND CLON

The invention relates to the field of cleaning liquids from mechanical impurities, namely for separating solid particles (sludge) from drilling mud. . Known hydraulic turbines, inclusive housing with connections for supplying the cleaned fluid and removal of sludge and hollow filter element. The purified liquid is discharged through the upper end (} of the connecting element l. The drawback of the device is low (the efficiency of the solid phase deposition process and the absence of its further compaction. As a result, the entire hydroturboclone cavity gradually fills the sludge. This worsens the conditions of the work filter. element, which adversely affects the quality of cleaning. Also known hydroturbine cyclone, consisting of 1SD11y of the body with the inlet pipe and nozzles drainage of purified liquid and mechanical A key, (}) of an eluting element with blades 1.2. j. The design of this hydro-turbo cyclone also does not provide an element that provides for the forced transfer of the solid phase to the lower part of the body. In addition, this hydro-turbo cyclone is not adapted to seal the spam. The closest in technical essence and the achieved result to the invention is a gndroturbashaslon, comprising a housing with an inlet branch pipe and branch pipes for discharging purified liquid and a thickened solid phase, a drive and concentrically mounted inside the core baleen filter element and screw W j. A disadvantage of the known apparatus is the possibility of driving the filter element shaded by the screw surface, since the wave excited by the vibrator is absorbed by the screw blade of the screw over the length of one winding step. The purpose of the invention is to increase the efficiency of separation and dehydration of the phase by the phase due to ensuring the forced displacement of the liquid phase through the Green filter element and its self-cleaning. The goal is achieved by the fact that in a hydro-turbine cyclone containing a housing with an inlet nozzle and nozzles for discharging purified liquid and a thickened solid phase, the filter element and cheeks are concentrically mounted inside the body and installed on the outside of the filter element and reduced to to the branch pipe of removal of the condensed solid phase with a step of turns, and the branch pipe of the removal of the condensed solid phase is provided with a rotary cap. FIG. 1 shows a hydro turbujlon, general view; in fig. 2 is a view A of FIG. 1. A hydroturbine cyclone consists of a body representing a cone tapering from the bottom, in the upper part of which it finds from the inlet 2, and in the lower part - the nozzle 3 for removing mechanical impurities. The nozzle 3 has an ellipse cross section. Inside the housing 1 there is a filtering element 4, the internal cavity of which is in communication with a hollow shaft representing the nozzle for discharging the purified liquid 5. Concentric to the filtering element 4 in the housing 1 is rotatably mounted. auger 6. The hydroturbine drive includes an electric motor 7, is kinematically coupled to the shaft 8 of the filter element 4, and a planetary gear 9, the carrier 1O of which is connected by a CQ screw 6. The inlet section of the nozzle 3 is adjusted by turning the crankshaft And around the central axis and its fixation in any position. The filter element rotates at a speed exceeding the speed of rotation of the screw. During operation of the hydroturbine cyclone, the cleaned fluid enters the housing 1 through the inlet nozzle 2. Rotating by the electric motor 7, the filtering element 4 separates the liquid phase of the cleaned fluid, which is withdrawn through the nozzle 5. The perforated cheek 6 during its rotation moves the solid phase to the bottom of the housing 1 and seal it. The degree of dehydration of the solid phase is regulated by means of loosening and fixing the lid. 1L. The different magnitudes of the velocities to the filter element and the auger are caused by the need to ensure the operation of these elements in technologically sound modes. ; The first one (filtering element) needs a speed greater than the second (auger), intended only for sedimentation and compaction (dehydration) of the solid phase, in order to provide a self-cleaning effect that prevents clogging of the mesh. The design of the filtering element allows one to achieve a self-cleaning effect, which consists in throwing sludge particles into the field of centrifugal forces arising during the rotation of the rotor of the installation. As for the screw, the latter is mounted concentric with the rotor on its outer side and rotates in the direction coinciding with the direction of rotation of the filter element. In addition, the screw is made of pressure, i.e., with the volume of the interturn space decreasing as it goes down. This allows the solid phase to be moved to the lower part of the housing and to dehydrate it by forcibly pushing the liquid phase through the filter element. I Such auger is especially necessary when separating solid and liquid phases with a slight difference in their specific weights, for example, when separating sludge from highly viscous drilling mud. Forced sedimentation of the solid phase also contributes to the improvement of the working conditions of the filter element and thereby the quality of separation. The proposed hydroturbine cyclone will improve the quality and increase the effect of cleaning the drilling mud due to forced precipitation and further y compaction of the solid phase and regulation of the degree of its dehydration. Formula and acquisition Hydroturboclone, comprising a case p with an inlet branch pipe and branch pipes for discharging purified liquid and a condensed solid phase. a drive element and filtering elements mounted concentrically inside the housing, and cheeks, characterized in that, in order to increase the efficiency of separation and dehydration of the solid phase by ensuring the forced displacement of the liquid phase through the filtering element and its self-cleaning, the auger is installed on the outside of the filtering element and is made with decreasing the direction to the branch pipe of withdrawal of the condensed solid phase in turns, and the branch pipe of the discharge of the condensed solid phase is provided with a rotary cover.
