Anti-blockage hydraulic classifier

Abstract

The invention relates to an anti-blockage hydraulic classifier which comprises a classifying cavity. A feeding pipe and an overflow pipe are mounted on the upper portion of the classifying cavity. Water inlets and a discharge outlet are formed in the bottom of the classifying cavity. A screen plate is fixedly arranged in the classifying cavity. A discharge barrel is mounted between the screen plate and the discharge outlet, and the upper end of the discharge barrel penetrates through the screen plate. The discharge barrel can freely rotate around the own axis. Spiral flow-guiding lines are formed on the inner wall of the discharge barrel, and transmission stripes are formed on the outer wall of the discharge barrel. Hydraulic turbines are further mounted in the classifying cavity and located below the screen plate, and a rotating shaft of each hydraulic turbine coincides with the axis of the corresponding water inlet. The outer walls of the hydraulic turbines are engaged with the outer wall of the discharge barrel. According to the classifier, the discharge outlet can be effectively prevented from being blocked, material discharge is promoted, and long-term stable work of the classifier is effectively guaranteed.

Description

technical field [0001] The invention relates to an industrial grading device, in particular to a hydraulic classifier. Background technique [0002] At present, the principles of the industrial hydraulic classifiers used in the market are all based on the principles of fluid mechanics. According to the different particle sizes and specific gravity of solid particles, under the action of external forces, their sedimentation speeds in the liquid are different, so as to realize the material Separated according to particle size and specific gravity, fine-grained or small specific-gravity solid particles are suspended in the liquid and become overflow, coarse-grained or large-specific solid particles settle at the bottom of the tank, and are discharged along the sand discharge device to realize continuous separation of materials A kind of grading equipment; in many beneficiation operations, hydraulic classification plays an important role; but the current hydraulic classifier c...
