Hydro-cyclone with flow channel screw pitch adjustable

Abstract

The invention provides a hydro-cyclone with the flow channel screw pitch adjustable. By means of the hydro-cyclone with the flow channel screw pitch adjustable, the problem that when different workingconditions are coped with by a single-type hydro-cyclone, the separating effect is poor is solved. The hydro-cyclone with the flow channel screw pitch adjustable is characterized in that a screw pitch-variable spiral flow channel module and an adjustable and regulatable inverted-cone module are arranged in a diameter-variable separating pipe; four columns of annular gap grooves are formed in thebottom of the diameter-variable separating pipe, each column of annular gap grooves comprise three annular gap grooves, and the annular gap grooves are distributed in a circumferential manner on the inner surface with the mutual included angle being 120 degrees; the screw pitch-variable spiral flow channel module comprises an inner-driven spiral column, an outer cylinder, limiting sliding blocks,sliding block nails, a trapezoid belt, a marking rotary knob, a square sealing ring and a sealing cover; the inner-driven spiral column and the outer cylinder are connected by the limiting sliding blocks and the sliding block nails; the limiting sliding blocks and the sliding block nails slide left and right in an outer cylinder groove through rotating the inner-driven spiral column, and the trapezoid belt is driven to move by the limiting sliding blocks; and the adjustable and regulatable inverted-cone module comprises a diameter-variable inverted cone, a circular ring-shape rotary knob, connecting rods, extending-and-contracting clamping columns and connecting pins, and the extending-and-contracting clamping columns are adjusted through rotating the circular ring-shape rotary knob.

Description

technical field [0001] The invention relates to a multiphase cyclone separation device. Background technique [0002] Hydrocyclones have been continuously researched and developed since they entered my country in the 1980s. With their simple operation, high efficiency, reliability, and economical practicability, hydrocyclones have been widely used in mining selection, oilfield oil-water separation in the same injection well, and chemical sewage treatment. . According to the different functions of cyclones, they can usually be divided into liquid-liquid cyclones and liquid-gas cyclones. Different types of cyclones are applied to different occasions. At present, most of the cyclone market is still dominated by liquid-liquid cyclones.

Problems solved by technology

According to the different functions of cyclones, they can usually be divided into liquid-liquid cyclones and liquid-gas cyclones. Different types of cyclones are applied to different occasions. At present, most of the cyclone market is still dominated by liquid-liquid cyclones. Compared with the swirl flow formed by the inlet at both ends, the spiral channel swirler can make the swirling liquid generate a relatively large centrifugal force, but a series of problems have also been encountered in the actual application process. One is that different working conditions make the multiphase flow liquid enter the spiral channel with different water pressure and speed, which greatly reduces the separation performance, and the actual working conditions cannot be changed. It is necessary to find a spiral channel cyclone suitable for this occasion , in the face of a variety of complex working conditions, it is necessary to develop a multi-occasion applicability cyclone separator
