Description

Technical Field

[0001] The invention belongs to the technical field of mineral detection and relates to a device for measuring a slurry sedimentation curve. Background Art

[0002] The wet beneficiation process of all ores cannot be separated from the concentration process. Concentration is often used to adjust the concentration of middlings and concentrates and tailings before filtration. The most commonly used concentration method is sedimentation concentration. Mineral type, particle size, concentration, added reagents, etc. will cause changes in sedimentation rate. Therefore, each mineral must be subjected to a sedimentation test according to actual conditions before sedimentation concentration. Traditional sedimentation tests are conducted in the laboratory, using a 1000-2000ml glass measuring cylinder, with grid paper pasted on the outer surface of the measuring cylinder to indicate the height. When measuring, it is necessary to use a stopwatch to time under sufficient light conditions, and observe the height position of the settlement line with the naked eye, usually measuring once every 20-30 seconds. However, this method is prone to large errors in human eye readings, so the measurement accuracy is not high and some slurry settlement lines are not obvious. The position of the settlement line cannot be determined by the naked eye, which can easily lead to an inability to measure. In addition, since the settlement process requires strong light to see the settlement line, and it is necessary to stare at the stopwatch and the settlement line position and the corresponding grid line readings throughout the process, the eyes must be highly concentrated, usually for 10-30 minutes or even 1 hour. The eye intensity is too high, and after the settlement process, the operator usually has eye discomfort or even stinging. Summary of the invention

[0003] The purpose of the present invention is to solve the problems in the prior art of large measurement error of slurry sedimentation curve, time-consuming and labor-intensive measurement, and to provide a slurry sedimentation curve measuring device.

[0015] The present invention is described in detail below in conjunction with the accompanying drawings:

[0016] like Figure 1-3As shown, a device for measuring slurry sedimentation curve includes a bracket 1, on which a transparent measuring tank 2 with a rectangular structure is provided, and on the rear side of the transparent measuring tank 2, an LED lamp 3 is provided, which is fixed on the bracket 1, and the length of the LED lamp 3 is consistent with the height of the transparent measuring tank 2. The LED lamp 3 can provide a light source and detect the slurry sedimentation of the transparent measuring tank 2. A plurality of photosensitive signal receivers 4 are provided on the front side of the transparent measuring tank 2. Specifically, a vertically arranged support rod 5 is provided on the bracket 1, and the support rod 5 is located on the front side of the transparent measuring tank 2. The photosensitive signal receivers 4 are fixed on the support rod 5 and arranged in a vertical direction. When the light emitted by the LED lamp 3 passes through the transparent measuring tank 2, it can be received by the corresponding photosensitive signal receiver 4. A computer 6 is provided on one side of the bracket 1, and the photosensitive signal receiver 4 is connected to the computer 6. The light signal received by the photosensitive signal receiver 4 can be transmitted to the computer 6, and the time when the light signal of the LED lamp 3 is received by the corresponding photosensitive signal receiver 4 is recorded by the computer 6, thereby facilitating the measurement and drawing of the sedimentation curve.

[0017] A stirring barrel 7 for stirring the slurry is provided above the transparent measuring tank 2. The stirring barrel 7 is fixed on the bracket 1. Specifically, a feeding port 8 is provided on the top of the stirring barrel 7, and a discharge pipe 9 for discharging material into the transparent measuring tank is connected to the bottom. A discharge valve 10 is provided on the discharge pipe 9. A vertically arranged rotating shaft 11 is provided in the stirring barrel 7. The bottom end of the rotating shaft 11 passes through the top of the stirring barrel 7. A plurality of blades 12 are provided on the rotating shaft 11. The blades 12 are located in the stirring barrel 7. The rotating shaft 11 can drive the blades 12 to rotate. A motor 13 for driving the rotating shaft 11 to rotate is connected to the top of the rotating shaft 11. The motor 13 is installed on the top of the stirring barrel 7. After the slurry is added to the stirring barrel 7, the slurry in the stirring barrel 7 can be stirred evenly by the blades 12, and then discharged into the transparent measuring tank 2 for facilitating the determination of the sedimentation curve.

[0018] The usage of the utility model is as follows:

[0019] First, add the slurry into the mixing barrel 7 through the feeding port 8, then start the motor 13, and drive the rotating shaft 11 and the blade 12 to rotate through the motor 13 to mix the slurry in the mixing barrel 7 evenly, then open the discharge valve 10 to discharge the slurry in the mixing barrel 7 into the transparent measuring tank 2 through the discharge pipe 9, and then turn on the LED light 3 to measure the slurry sedimentation curve. Since the evenly stirred slurry enters the transparent measuring tank 2, it can block the light of the LED light 3 from penetrating the transparent measuring tank 2, so that the photosensitive signal receiver 4 on the front of the transparent measuring tank 2 cannot receive the light signal. When the slurry starts to sink to the bottom, the liquid on the upper part of the transparent measuring tank 2 gradually becomes clear, making L The light of the ED lamp 3 can pass through the upper part of the transparent measuring tank 2 and be received by the corresponding photosensitive signal receiver 4, and then the photosensitive signal receiver 4 transmits the signal to the computer 6 and records the time. As the sedimentation proceeds, the light of the LED lamp 3 passing through the transparent measuring tank 2 gradually increases from top to bottom, and the remaining photosensitive signal receivers 4 receive the light signal from top to bottom in turn, and send signals to the computer 6, and the time is recorded through the computer 6. When the sedimentation is completed, the received signals and the recorded time information can be summarized by the computer to draw a sedimentation curve. Compared with the traditional manual method, the use of this device is convenient and fast, and greatly saves manpower.
