Ore pulp centrifugal concentration and separation device for laboratory

Abstract

The invention relates to the field of coal preparation plant coal slime water ore pulp concentration sedimentation and separation control, and discloses an ore pulp centrifugal concentration and separation device for a laboratory. The device is composed of an ore pulp feeding pipe, a feeding port, a feeding conical flow guide plate, an upper conical cover, a bottom plane, a collecting ring grooveouter wall, a collecting ring groove inner wall and the like. The ore pulp feeding pipe extends into the feeding port; the feeding port and the upper conical cover are integrated, the feeding conicalflow guide plate is fixed below the upper conical cover, and the upper conical surface is connected to the bottom plane through an adjusting screw rod; a drainage pipe is located in the center of thebottom plane, and the drainage pipe fixes a gear set, and the other end of the gear set is connected with a shaft of a motor; the motor drives the device to rotate at a high speed to generate a centrifugal field inside the device. The density of fine particles in ore pulp is larger than that of clear water in the ore pulp, so the centrifugal forces borne by the fine particles and the clear water in a centrifugal field are different, the fine particles slide into a collecting ring groove along the inner wall of the upper conical cover, the clear water is gathered to the center along the bottomplane, and finally the particles and the clear water are separated.

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...

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
