Embodiment 1

[0034] Such as Figure 1-Figure 3 Commonly shown, the non-powered deep cone thickener rheological on-line adjustment device includes a sand bin 1, and the sand bin 1 includes a straight barrel section 2 and a cone barrel section 3 arranged up and down, and the lower end of the straight barrel section 2 and the upper end of the cone barrel section 3 Several first damping vibrators 4 are installed on the warehouse wall, and several second damping vibrators 5 are installed on the warehouse wall at the lower end of the cone section 3, and each second damping vibrator 5 and the warehouse of the cone section 3 A position adjustment mechanism is arranged between the walls, and a number of mixing water nozzles 6 are installed on the warehouse wall of the cone section 3, and the position of each mixing water nozzle 6 is consistent with the first damping vibrator 4 and the second damping vibrator. The position of the vibrator 5 is corresponding, and all the mixing water nozzles 6 are co...

Embodiment 2

[0048] The rheological on-line adjustment process of the unpowered deep cone thickener includes the following steps:

[0049] S1. The settled mortar enters the lower end of the straight barrel section 2 and the cone section 3 of the sand bin 1, and the controller 8 controls the first damping vibrator 4 and the second damping vibrator 5 to start to drive the mortar to vibrate to avoid the mortar hanging wall.

[0050]S2. After the first concentration detection sensor 10 detects that the concentration of the mortar reaches a predetermined value, the controller 8 controls the sand discharge valve 11 to open, and the mortar in the cone section 3 is discharged from the sand bin 1 through the sand discharge pipe 9 .

[0051] S3. The second concentration detection sensor 28 monitors the concentration of the mortar in the cone section 3 in real time, and controls the opening and closing of the mixing water nozzle 6 and the position adjustment mechanism according to the monitored conce...

Abstract

The invention provides an unpowered deep-cone thickener rheological property on-line adjusting device and an adjusting process. The adjusting device comprises a sand silo and an on-line control system; the sand silo comprises a straight cylinder section and a cone cylinder section; a plurality of first damping vibrators are installed at the lower end of the straight cylinder section and the upper end of the cone cylinder section, and a plurality of second damping vibrators are installed on the silo wall of the lower end of the cone cylinder section; a position adjusting mechanism is arranged between each second damping vibrator and the conical barrel section, a plurality of size mixing water spray heads are further installed on the bin wall of the conical barrel section, all the size mixing water spray heads are jointly connected with a wind and water station, a concentration monitoring mechanism is installed in the conical barrel section, the online control system comprises a controller, a sand discharging pipe is installed at the bottom of the conical barrel section, and a first concentration detection sensor and a sand discharging valve are mounted on the sand discharging pipe. Efficient vibration activation of the slurry in the conical barrel section of the sand silo is achieved, the problem that the slurry is hung on the wall due to the poor rheological property of the slurry is solved, and meanwhile precise control over the slurry concentration and automatic steady-flow sand discharging are achieved.

Description

technical field [0001] The invention relates to the technical field of mine environmental protection equipment, in particular to an on-line rheological adjustment device and an adjustment process for a non-powered deep cone thickener. Background technique [0002] The non-powered deep cone thickener is a kind of equipment used in the mine filling system. It is mainly used for thickening and dehydrating the low-concentration tailings produced in the mining industry. Its shape is similar to a settling funnel. After entering the sand bin of the thickener, the ore particles suspended in the pulp settle down due to their own gravity, and the pulp is divided into clarified liquid and high-concentration sediment. [0003] At the bottom of the sand bin, when the concentration of tailings reaches a certain value, the following problems are likely to occur: first, the rheology of the slurry becomes poor and the viscosity will be relatively large, and a large amount of slurry is likely...
