Description

Technical Field

[0001] The present application relates to the technical field of thickening tank sedimentation, and in particular to a dosing device for a thickening tank. Background Art

[0002] A thickener is a solid-liquid separation device based on gravity settling. It's typically constructed of concrete, wood, or welded metal plates in the form of a shallow cylindrical trough with a conical bottom. Its operating principle is to concentrate a slurry containing solid particles through gravity settling, causing the solid particles to settle to the bottom of the tank, forming a dense bed. During this process, heavier solid particles settle by gravity, while lighter liquid rises to the top of the tank, forming a clarified liquid. As tailings liquid is continuously injected into the thickener, the clarified liquid overflows through the overflow plate and is recycled.

[0003] During the production process, flocculants are usually added to the thickening tank to improve the sedimentation effect of solid particles. At present, the agent is usually added directly to the thickening tank. Due to the large thickness of the thickening tank, this method can easily lead to uneven distribution of the flocculant, affecting the flocculation effect. There is also a method of adding flocculants to the tailings liquid pipeline. The advantage of this method is that the flocculant and tailings liquid can be fully mixed in advance to ensure uniform distribution of the flocculant. However, this method requires more accurate control of the amount of flocculant added, the flow rate of the tailings liquid in the pipeline, and the solid particle content of the tailings liquid. Otherwise, it is easy to cause the tailings liquid to settle prematurely in the pipeline, causing pipeline blockage. Utility Model Content

[0004] In order to solve or partially solve the problems existing in the related art, the present application provides a dosing device for a thickening tank, which can mix the tailings liquid and flocculant in advance to ensure the uniformity of the flocculant in the mixed liquid, and there is no need to add the flocculant to the tailings liquid pipeline to ensure the smooth flow of the pipeline.

[0005] The present application provides a dosing device for a thickening tank, comprising a mixing tank, a water inlet pipe, a dosing mechanism, and an operating platform.

[0024] See also Figure 1-3A dosing device for a thickening tank includes a mixing tank 1, a water inlet pipe 2, a dosing mechanism 3, and an operating platform 7. The mixing tank 1 is fixedly installed on the top of the thickening tank 6 through a bracket 15, and the mixing tank 1 is divided into a mixing section 11 and a diversion section 12. The mixing section 11 has a semicircular structure to increase the length of the mixing section 11 within a limited space, thereby ensuring that the flocculant and the tailings liquid are fully mixed. One end of the mixing section 11 is a water inlet end 13, which is connected to a water inlet pipe 2 and is connected to a water pump at the tailings pool through the water inlet pipe 2. By starting the water pump, the tailings liquid in the tailings pool can be pumped into the mixing tank 1. The other end of the mixing section 11 is connected to the diversion section 12. The diversion section 12 is vertically arranged at the center of the thickening tank 6, and a water outlet 14 is opened at the bottom of the diversion section 12. During use, the tailings liquid and the flocculant are fully mixed in the mixing section 11 and then discharged from the diversion section 12 into the thickening tank 6, wherein the heavier solid particles settle by gravity, while the lighter liquid rises to the upper part of the tank body to form a clarified liquid. As the tailings liquid is continuously injected into the thickening tank 6, the clarified liquid overflows and is discharged from the overflow plate 61; furthermore, the height of the water outlet 14 is 3-5m lower than the top surface of the overflow plate 61, so that the diversion section 12 is inserted into the liquid in the thickening tank 6, so that the mixed liquid is discharged into the thickening tank 6 from below the clarified liquid layer, reducing the disturbance to the clarified liquid layer and ensuring the effect of solid-liquid separation.

[0025] An operating platform 7 is also installed on the top of the thickening tank 6. The operating platform 7 is connected to the ground by stairs, making it convenient for workers to go up and down. A dosing mechanism 3 for adding reagents to the mixing tank 1 is installed on the operating platform 7, including a dosing box 31, a valve 33, and a liquid medicine pipe 34. The dosing box 31 is fixed to the operating platform 7 by a support leg, and a valve 33 is provided at the bottom of the dosing box 31. The outlet of the valve 33 is connected to the water inlet 13 of the mixing tank 1 through the liquid medicine pipe 34. The liquid medicine pipe 34 is tilted, with the side near the valve 33 higher and the side near the mixing tank 1 lower. When in use, the flocculant and clean water are first mixed according to the demand to form a flocculation solution. By opening the valve 33, the flocculation solution flows into the mixing tank 1 through the liquid medicine pipe 34 under the dual action of water pressure and gravity to mix with the tailings liquid. The amount of flocculation solution added can be controlled by controlling the opening and opening time of the valve 33. The valve 33 can be a manual valve or an electronically controlled valve.

[0026] Furthermore, in order to facilitate monitoring of the remaining amount of flocculation solution in the dispensing box 31 , an observation window 32 is provided on the dispensing box 31 , and a scale line is marked on the observation window 32 , so that workers can intuitively understand the amount of flocculation solution added.

[0027] After the tailings liquid is processed, some of it will remain in the mixing tank 1. If it is not processed, when the tailings liquid dries up, the solid particles therein will easily form lumps in the mixing tank 1, affecting subsequent use. Therefore, a cleaning pipe 5 is provided at the water inlet 13 of the mixing tank 1. The end of the cleaning pipe 5 is connected to a cleaning pump. When production is completed, the cleaning pump is turned on to flush the mixing tank 1 with clean water to avoid residual tailings liquid.

[0028] A control console 4 is installed on the operating platform 7, through which the start and stop of the water pump and the cleaning pump can be controlled.

[0029] Specific working process:

[0030] Prepare the flocculation solution in the dispensing box 31, start the pump to pump the tailings liquid in the tailings pond into the mixing tank 1, and open the valve 33 to add the flocculation solution into the mixing tank 1. After the tailings liquid and the flocculation solution are fully mixed in the mixing tank 1, they are discharged from the outlet 14 to the thickening tank 6 for solid-liquid separation.
