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 proposes an on-line rheological adjustment device and adjustment process for a non-powered deep cone thickener, including a sand bin and an on-line control system. The sand bin includes a straight barrel section and a cone section. There are several first damping vibrators, and several second damping vibrators are installed on the warehouse wall at the lower end of the cone section. A position adjustment mechanism is arranged between each second damping vibrator and the cone section. There are also several mixing water nozzles installed on the warehouse wall, all the mixing water nozzles are connected to a Fengshui station, the inside of the cone section is equipped with a concentration monitoring mechanism, the online control system includes a controller, and the bottom of the cone section is installed with a row The sand pipe, the first concentration detection sensor and the sand discharge valve are installed on the sand discharge pipe. The invention realizes the high-efficiency vibration activation of the slurry in the cone section of the sand bin, and solves the problem of slurry hanging caused by poor rheology of the slurry. At the same time, it realizes the precise control of the slurry concentration and the automatic steady flow of sand.

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...
