A flow path pitch adjustable hydrocyclone

Abstract

The utility model relates to an adjustable flow channel pitch hydrocyclone. The main purpose is to solve the problem that a single type of cyclone has poor separation effect in different working conditions. It is characterized in that: a variable-pitch spiral flow channel module and an adjustable inverted cone module are built in the variable-diameter separation tube; there are 4 rows of annular gap grooves at the bottom of the variable-diameter separation tube, and there are 3 gap grooves in each row with mutual angles Distributed on the inner surface in a 120° circle; the variable-pitch spiral flow channel module includes an inner drive screw column, an outer cylinder, a limit slider, a slider nail, a trapezoidal belt, a coding knob, a square seal ring, and a sealing cover. The slider and the slider nail link the inner drive screw column and the outer cylinder together, and the limit slider and the slider nail slide left and right in the groove of the outer cylinder by rotating the inner drive screw column, and the limit slider drives the trapezoidal belt to move; The adjustable inverted cone module includes a variable-diameter inverted cone, a ring knob, a connecting rod, a telescopic clamping column and a connecting pin, and the telescopic clamping column is adjusted by rotating the circular ring 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. .

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
