One-way heart pump centrifuge internal flow channel

Abstract

The invention discloses a one-way heart pump centrifuge internal flow channel, which is characterized in that a liquid inlet and outlet diverter valve is hermetically assembled and connected with a heavy liquid centripetal pump, and mixed liquid passes through a liquid inlet pipe in the middle of the heavy liquid centripetal pump and then enters a liquid inlet cavity between a specific gravity ring and a disc fixing disc, wherein the disc fixing disc is arranged at the top end of a disc sedimentation area, and the specific gravity ring is arranged on the disc fixing disc; the mixed liquid enters a drum through the cavity; a heavy liquid flow channel is arranged between the specific gravity ring and the centrifuge drum; the heavy liquid enters a heavy liquid jet pipe through the flow channel, then, the heavy liquid is extracted to the liquid inlet and outlet diverter valve through the heavy liquid centripetal pump and discharged through a heavy liquid outlet flow channel; a light liquidoutlet flow channel is located at the lowermost portion of the disc sedimentation area near the rotation center of the centrifuge drum; and a fixed installation hole is formed in a disc of the disc sedimentation area. The disc in the sedimentation disc area is not provided with a blanking hole, a blanking baffle, a flow guide plate and other devices, so that blockage of the blanking hole, the blanking baffle and the flow guide plate caused by fiber substances frequently mixed in the mixed liquid can be avoided.

Description

technical field [0001] The invention belongs to the technical field of centrifuges with rotating drums, and is mainly used for separating mixtures with different densities of phases and the density of the solid phase must be greater than that of any liquid phase. road. Background technique [0002] The settling disc centrifuge can quickly and continuously separate solids and liquids, liquids and liquids, solids and two mixed liquids with different specific gravity. The specific gravity of the solid must be greater than the specific gravity of the liquid to be separated. , food, and industrial industries have a wide range of applications. At present, there are mainly two types of decanter centrifuges in the domestic and foreign markets: one-way heart pump centrifuges and two-way heart pump centrifuges. [0003] At present, the common problems of unidirectional heart pump centrifuges and bidirectional heart pump centrifuges include complex flow channel structure, fibrous mat...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the problems caused by the complex structure of the flow channels in the above-mentioned one-way heart pump centrifuge and the two-way heart pump centrifuge, the blockage of the blanking hole by fibrous materials, and the connection between the light liquid outlet hole and the disc chassis and the drum. Improve the internal channel structure of the centrifuge due to problems such as blockage, heavy equipment, large volume, and unsuitability for mobile work scenarios
