Embodiment 1

[0035] In Panzhihua Iron and Steel Midi concentrator, the average volume flow rate of non-magnetic products of each roughing magnetic separator is 180 meters 3 / hour with a minimum volumetric flow rate of 150 meters 3 / hour (equivalent to 0.042 meters 3 / Second). The concentration of this non-magnetic product is 20%, the fineness is 45%-200 mesh, the maximum particle size is 0.35 mm, and the particle density is 2700 kg / m 3 According to table 8.9-26 of "Mineral Processing Design Manual" (2007 Edition), the suspension velocity of the largest particle is 1.4 m / s. In order to ensure that the non-magnetic product does not settle when passing through the pipeline, the maximum cross-sectional area of ​​the pipeline is (0.042 / 1.4=) 0.03 meters 2 . When a circular pipe is used to discharge the non-magnetic product, the calculated maximum diameter of the pipe is ( =0.195m=195mm, the maximum diameter of the standard size circular pipe available is 180mm (take the standard pipe). ...

Embodiment 2

[0042] In the Luoci concentrator of Kunming Iron and Steel Co., Ltd., the average volume flow rate of non-magnetic products of each weak magnetic field magnetic separator is 40 meters 3 / hour with a minimum volumetric flow rate of 30 meters 3 / hour (equivalent to 0.0084 meters 3 / Second). The concentration of this non-magnetic product is 30%, the fineness is 75%-200 mesh, the maximum particle size is 0.15 mm, and the particle density is 2600 kg / m 3 According to table 8.9-26 of "Mineral Processing Design Manual" (2007 Edition), the suspension velocity of the largest particle is 1.4 m / s. In order to ensure that the non-magnetic product does not settle when passing through the pipeline, the maximum cross-sectional area of ​​the pipeline is (0.0084 / 1.4=) 0.006 meters 2 . When a circular pipe is used to discharge this non-magnetic product, the calculated maximum diameter of the pipe is =0.087m=87mm, the maximum diameter of the standard size circular pipe available is 83mm (t...

Embodiment 3

[0050] In a newly designed concentrator, the average volume flow rate of non-magnetic products of each magnetic separator is 30 meters 3 / hour, the pulp volume fluctuation coefficient is 1.2, and the minimum volume flow rate is (30 / 1.2=) 25 meters 3 / hour (equivalent to 0.0069 meters 3 / Second). The concentration of this non-magnetic product is 25%, the fineness is 50%-200 mesh, the maximum particle size is 0.3 mm, and the particle density is 2650 kg / m 3 According to table 8.9-26 of "Mineral Processing Design Manual" (2007 Edition), the suspension velocity of the largest particle is 1.4 m / s. In order to ensure that the non-magnetic product does not settle when passing through the pipeline, the maximum cross-sectional area of ​​the pipeline is (0.0069 / 1.4=) 0.0049 meters 2 . When a circular pipe is used to discharge the non-magnetic product, the calculated maximum diameter of the pipe is ( = 0.079m = 79mm, the maximum diameter available for standard size circular pipes ...

Abstract

The invention relates to a small-section communicating pipe device and method for keeping a pulp surface in a wet magnetic separator tank body horizontal, belonging to the technical field of mineral process engineering. The small-section communicating pipe device for keeping the pulp surface in the wet magnetic separator tank body horizontal comprises a non-magnetic product discharging pipe, a pulp tank body, a magnetic product discharging pipe, a magnetic product sucking and conveying device, a feeding hole, an overflow hole and a rack, and further comprises a small-section communicating pipe device, wherein the small-section communicating pipe device is connected to an outlet of the non-magnetic product discharging pipe, and a discharging hole of the small-section communicating pipe device is equal to the highest pulp surface in the pulp tank body. According to the method, by determining that after a raising part of the small-section communicating pipe device reaches the maximum area, the small-section communicating pipe device is connected to an outlet position of the discharging pipe of the non-magnetic product of the wet magnetic separator, and the discharging hole of the small-section communicating pipe device is equal to the highest pulp surface in the pulp tank body, thus a subsequent magnetic separation process is performed. According to the small-section communicating pipe device and method, the pulp surface of the wet magnetic separator can be kept horizontal by using a simple and reliable communicating pipe method.

Description

technical field [0001] The invention relates to a small-section communication pipe device and method for maintaining the level of the pulp surface in a tank body of a wet-type magnetic separator, and belongs to the technical field of mineral processing engineering. Background technique [0002] Wet magnetic separators include wet magnetic separators with pulp tanks and wet magnetic separators without pulp tanks. Since the separation effect of wet magnetic separators with pulp tanks is better than that of wet magnetic separators without pulp tanks, wet magnetic separators without pulp tanks are used less and less. Commonly used wet magnetic separators The machines are all wet magnetic separators with slurry tanks. [0003] The main components of the wet magnetic separator with pulp tank body include: pulp tank body, magnetic mineral particle adsorption device (magnet or magnetic gathering medium), raw ore feeding device, magnetic mineral particle transport device, magnetic p...
