A centrifugal concentration and separation device for ore pulp used in the laboratory

Abstract

The invention relates to the field of thickening, sedimentation and separation control of coal slurry, water ore slurry in a coal preparation plant, and discloses a centrifugal concentration and separation device for ore pulp used in a laboratory. , the upper cone cover, the bottom plane, the outer wall of the collecting ring groove, the inner wall of the collecting ring groove, etc., the slurry feeding pipe extends into the feeding port, the feeding port is integrated with the upper cone cover, and the feeding conical deflector It is fixed under the upper cone cover, the upper cone surface is connected to the bottom plane through the adjusting screw rod, the drain pipe is located in the center of the bottom plane, the drain pipe is fixed to the gear set, and the other end of the gear set is connected to the shaft of the motor, and the motor drives the device to rotate at high speed, and in the A centrifugal field is generated inside the device; the density of the fine particles in the pulp is greater than that of the clean water in the pulp, and the centrifugal force received by the fine particles and clean water in the centrifugal field is different, so that the fine particles slide down to the collection ring groove along the inner wall of the upper cone cover, and the clean water Gather along the bottom plane to the center, and finally realize the separation of particles and clear water.

Description

technical field [0001] The invention relates to the field of thickening, sedimentation and separation control of coal slime water ore slurry in a coal preparation plant, in particular to a centrifugal concentration and separation device for ore pulp used in a laboratory. Background technique [0002] The professional laboratory of mineral processing engineering often involves the experiment of solid-liquid separation of slurry containing mineral particles, and studies the mechanism and influencing factors of the sedimentation and separation of fine mineral particles in the slurry under various conditions. Generally, an ordinary graduated cylinder is used as the container, and the capacity of the graduated cylinder is determined according to the needs of the test. In order to be able to observe the sedimentation velocity intuitively, a scale is usually attached to the outer wall of the graduated cylinder, so as to facilitate the observation of the sedimentation distance and th...

AI Technical Summary

Problems solved by technology

Flocculation and sedimentation, that is, add some polymer flocculants and other drugs to the pulp, form long-chain molecules in the pulp and network the fine mineral particles in the pulp together to form larger flocs, and its sedimentation speed is slower than natural sedimentation Good, but the flocs in the settlement area are also loose, not dense, and the clarified liquid is turbid; at the same time, the agent has certain corrosion and damage to the human body, and also has many shortcomings and drawbacks; in order to solve the above shortcomings and drawbacks, a This kind of centrifugal concentration and separation device for ore pulp used in the laboratory does not require chemicals, and realizes the efficient and rapid concentration and separation of fine mineral particles under the action of centrifugal force
