Embodiment 1

[0041] like figure 1 A kind of coal slime water pre-magnetization shown, flocculation settling test device comprises settling column, magnetic field shielding cover 6, agitator, electromagnetic coil 5, the agitator control system that is used to control described agitator work and is used to control electromagnetic coil 5 working magnetic field adjustment system, the settling column includes a base 9, a settling column body 1 and a sealing cover 4, the settling column body 1 is a hollow cylindrical structure with openings at both ends, the settling column body 1 The lower end is sealed and fixed at the top center of the base 9, the settling column body 1 is perpendicular to the base 9, the sealing cover 4 is arranged on the top of the settling column body 1 and matches with the top of the settling column body 1, The electromagnetic coil 5 is sleeved on the outside of the settling column body 1, the magnetic field shield 6 is sleeved on the outside of the electromagnetic coil 5...

Embodiment 2

[0058] like Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the stirring impeller 3 is a radial flow impeller, the number of blades of the stirring impeller 3 is four and the upper outer edges of the four blades are linear structures.

[0059] In this embodiment, the structures, connections and working principles of other parts are the same as those in Embodiment 1.

Abstract

The invention discloses a slime water pre-magnetization and flocculation settlement test device which comprises a settlement column, a magnetic field shielding cover, a stirrer, an electromagnetic coil, a stirrer control system and a magnetic field adjusting system. The settlement column comprises a base, a settlement column cylinder and a sealing cover. A lower end of a column body of the settlement column is sealed and fixed to a top center of the base, the sealing cover is set at a top of the column body of the settlement column, the electromagnetic coil sleeves the outer side of the columnbody of the settlement column, the magnetic field shielding cover sleeves the outer side of the electromagnetic coil, and the magnetic field shielding cover is set at the top of the base. The stirrercomprises a driving motor and a stirring impeller, an output shaft of the driving motor is fixedly connected to a driving end of the stirring impeller, the driving motor is installed in the base, andthe stirring impeller is arranged at an inner bottom end of the column body of the settlement column. The device can realize the laboratory exploration of the magnetic field strength and magnetization time required for the settlement of different properties of slime water, and therefore, the preliminary basic data is provided for promoting the industrialization process of the pre-magnetization and flocculation settlement technology of the slime water.

Description

technical field [0001] The invention relates to a coal slime water treatment test device, in particular to a coal slime water premagnetization, flocculation and settlement test device. Background technique [0002] Coal washing usually uses water or a mixture of water as the washing medium, and a large amount of slime water (a mixed dispersion system composed of water and solid fine mud particles) will be produced during the production process. If the slime water is not properly treated and recycled, it will cause serious environmental pollution and waste of water resources. On the basis of comprehensive consideration of the coal washing process, it is very important for green coal preparation to control the circulating water system through the comprehensive treatment of slime water to realize the closed cycle of washing water, and the clarification of slime water is a key part of comprehensive treatment of slime water. [0003] The traditional coal slime water clarificatio...
