Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of slurry sampling equipment, and in particular to a simple tailings slurry sampling device. Background Technology
[0002] Tailings sampling is a crucial step in the mineral processing flow for checking and adjusting the process. By sampling, data such as tailings grade, concentration, and fineness can be obtained. This data is essential for analyzing the overall effectiveness of the processing plant, adjusting process parameters, and evaluating the utilization efficiency of mineral resources. Simultaneously, tailings sampling serves as a direct basis for monitoring and evaluating mineral processing production. With the gradual depletion of mineral resources, tailings reprocessing has become an important means of improving mineral resource utilization efficiency, and tailings sampling provides fundamental data support for tailings reprocessing, contributing to efficient resource recovery and sustainable environmental development. Currently, most mineral processing plants suffer from uneven sampling of tailings slurry due to unreasonable selection of sampling points and tools. This results in significant errors in the measured data indicators of the tailings slurry, particularly affecting important indicators such as slurry fineness, concentration, and grade. This fails to provide effective data support for various process flows, leading to unstable production, difficulty in controlling indicators, and low tailings utilization efficiency, further hindering the recycling of tailings resources. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a simple tailings slurry sampling device.
[0004] This utility model is achieved through the following technical solution: a simple tailings slurry sampling device, comprising a first slurry pipe, a second slurry pipe, a third slurry pipe, an electric valve, a slurry pump, a sampler, and a concentration vessel; one end of the first slurry pipe is connected to the tailings pond outlet, and the other end is connected to the slurry pump; the electric valve is installed on the first slurry pipe near the tailings pond; several second slurry pipes are provided, the inlets of several second slurry pipes are connected to the first slurry pipe, the connection is located on the pipeline between the electric valve and the slurry pump, and the outlets of several second slurry pipes are connected in parallel to the third slurry pipe; the sampler is located below the outlet of the third slurry pipe, the concentration vessel is located below one outlet of the sampler, and the other outlet of the sampler leads to a buffer tank.
[0005] All three types of slurry pipes are equipped with valves. When it is necessary to measure various data indicators of tailings slurry, the slurry pump is started and the electric valve is opened. Simultaneously, when the valve of the first slurry pipe is opened, the slurry will flow to the second and third slurry pipes, and finally flow to the sampler for reduction. The sampler has two outlets: the slurry from one outlet flows to the concentration vessel for slurry sampling and measurement of various indicators, and the slurry from the other outlet flows to the buffer tank for recycling. The evenly distributed second slurry pipes can solve problems such as uneven sampling, unrepresentative samples, and inaccurate data indicators caused by improper selection of sampling points and sampling tools.
[0006] The second slurry pipe has three sections, which are evenly installed on the pipe through which the central cross-section of the first slurry pipe passes. Two of the sections are located at the two ends of the horizontal diameter of the first slurry pipe, and the other section is located at the lower end of the vertical diameter of the first slurry pipe.
[0007] The first slurry pipe is divided into three equal sections, which are connected by flanges. The second slurry pipe is connected to the middle section of the first slurry pipe by a flange. The slurry pump is connected to the first slurry pipe by a flange, and the first slurry pipe is connected to the tailings pond outlet by a flange.
[0008] The first slurry pipe is made of PE material and has a nominal diameter of 355 mm.
[0009] The second slurry pipe is made of PE material and has a nominal diameter of 20mm.
[0010] The third slurry pipe is made of PE material and has a nominal diameter of 50mm.
[0011] The sample divider is a two-part sample divider made of stainless steel, with a diameter of 200 mm and a height of 300 mm.
[0012] The concentration pot is made of 304 stainless steel and has a volume of 0.75L.
[0013] The slurry pump is a slurry pump made of stainless steel, with an outlet diameter of 200 mm.
[0014] The electric valve is made of ceramic material.
[0015] Compared with existing technologies, the advantages of this invention are as follows: When it is necessary to measure various data indicators of tailings slurry, the device starts the slurry pump and opens the electric valve. Simultaneously, when the valve of the first slurry pipe is opened, the slurry flows to the second slurry pipe. After passing through three second slurry pipes, the slurry converges into the third slurry pipe and finally flows to the sampler for reduction. The sampler has two outlets: the slurry from one outlet flows to the concentration vessel for slurry sampling and measurement of various indicators, and the slurry from the other outlet flows to the buffer tank for recycling. This device can solve problems such as uneven sampling, unrepresentative samples, and inaccurate data indicators caused by improper selection of sampling points and sampling tools. The device has a simple structure, is easy to manufacture, highly practical, and easy to maintain; it also has low economic cost and low investment. Attached Figure Description

[0022] See Figures 1 to 3 This is a simple tailings slurry sampling device, comprising a first slurry pipe 2, a second slurry pipe 3, a third slurry pipe 6, an electric valve 4, a slurry pump 1, a sampler 7, and a concentration vessel 8. One end of the first slurry pipe 2 is connected to the outlet of the tailings pond 5, and the other end is connected to the slurry pump 1. The electric valve 4 is installed on the first slurry pipe 2 near the side of the tailings pond 5. Several second slurry pipes 3 are provided, and the inlets of several second slurry pipes 3 are connected to the first slurry pipe 2. The connection is located on the pipeline between the electric valve 4 and the slurry pump 1. The outlets of several second slurry pipes 3 are connected in parallel and then connected to the third slurry pipe 6. The sampler 7 is located below the outlet of the third slurry pipe 6, and the concentration vessel 8 is located below one outlet of the sampler 7. The other outlet of the sampler 7 leads to a buffer tank 9.
[0023] All three types of slurry pipes are equipped with valves. When it is necessary to measure various data indicators of tailings slurry, the slurry pump 1 is started and the electric valve 4 is opened. At the same time, when the valve of the first slurry pipe 2 is opened, the slurry will flow to the second slurry pipe 3 and the third slurry pipe 6, and finally flow to the sampler 7 for reduction. The sampler 7 has two outlets. The slurry from one outlet flows to the concentration vessel 8 for slurry sampling and measurement of various indicators, and the slurry from the other outlet flows to the buffer tank 9 for recycling. The evenly distributed second slurry pipe 3 can solve the problems of uneven sampling, unrepresentative ore samples, and inaccurate data indicators caused by improper selection of sampling points and sampling tools.
[0024] There are three second slurry pipes 3. The three second slurry pipes 3 are evenly installed on the pipe through which the central cross-section of the first slurry pipe 2 passes. Two of the interfaces are located at the two ends of the horizontal diameter of the first slurry pipe 2, and the other interface is located at the lower end of the vertical diameter of the first slurry pipe 2.
[0025] The first slurry pipe 2 is divided into three equal sections, which are connected by flanges. The second slurry pipe 3 is connected to the middle section of the first slurry pipe 2 by flanges. The slurry pump 1 is connected to the first slurry pipe 2 by flanges, and the first slurry pipe 2 is connected to the outlet of the tailings pond 5 by flanges.
[0026] The first slurry pipe 2 is a slurry pipe made of PE material with a nominal diameter of 355mm.
[0027] The second slurry pipe 3 is a slurry pipe made of PE material with a nominal diameter of 20mm.
[0028] The third slurry pipe 6 is a slurry pipe made of PE material with a nominal diameter of 50mm.
[0029] The sampler 7 is a two-part sampler made of stainless steel, with a diameter of 200 mm and a height of 300 mm. The sampler 7 has two slurry outlets inside, which helps to uniformly divide the slurry.
[0030] Concentrate pitcher 8 is made of 304 stainless steel and has a volume of 0.75L. This concentrate pitcher 8 has excellent corrosion resistance, high temperature resistance and low temperature resistance.
[0031] Slurry pump 1 is made of stainless steel and has an outlet diameter of 200mm. The selected slurry pump model is 200ZGB-120, which is a commercially available product and will not be analyzed in detail. The stainless steel slurry pump 1 has advantages such as low energy consumption, high wear resistance, high impact resistance, low noise, and long service life.
[0032] Electric valve 4 is made of ceramic material. It is installed on the first slurry pipe 2, 300mm from the outlet of tailings pond 5. The ceramic material electric valve 4 has excellent wear resistance, corrosion resistance, and good chemical stability; it is a commercially available product and will not be analyzed in detail.
[0033] In this embodiment, the first slurry pipe 2 is a DN355 slurry pipe, the second slurry pipe 3 is a DN20 slurry pipe (also known as a 6-point slurry pipe), and the third slurry pipe 6 is a DN50 slurry pipe (also known as a 2-inch slurry pipe). The sampler 7 is fixedly installed below the outlet of the third slurry pipe 6 via a bracket. There are three second slurry pipes 3: two installed on the side wall of the first slurry pipe 2, each including a horizontal section, a vertical section connected to the horizontal section, and an inclined section connected to the vertical section. The free end of the horizontal section is connected to the first slurry pipe 2, and the lower outlet of the inclined section is connected in parallel with the other second slurry pipes 3. The horizontal section is 500mm long, and the vertical section is 250mm long. All three types of slurry pipes are made of PE material, which has excellent corrosion resistance and stress crack resistance, and is not easily affected by the site environment during use. Three pipes with different nominal diameters were selected to meet the slurry volume requirements.
[0034] In this embodiment, the first slurry pipe 2 is connected to the outlet of the tailings pond 5 via a flange. This design not only facilitates installation and maintenance but also ensures the smoothness and safety of the mineral sample during transportation.
[0035] During operation, firstly, the slurry pump 1 and electric valve 4 are turned on, and the valves on the second slurry pipe 3 and the third slurry pipe 6 are opened. The slurry from the tailings pond 5 flows into the second slurry pipe 3 after passing through the first slurry pipe 2, and then merges and enters the third slurry pipe 6. The slurry then enters the sampler 7 for reduction. The reduced slurry then enters the concentration tank 8 and the buffer tank 9 respectively. When the slurry volume in the concentration tank 8 reaches the required standard, the operator closes the valves on the third slurry pipe 6 and the second slurry pipe 3. With simple operation by the operator, uniform sampling of the slurry can be achieved, ensuring the accuracy and representativeness of the sampled minerals. This solves the problems of uneven sampling, unrepresentative mineral samples, and inaccurate data indicators caused by improper selection of sampling points and sampling tools.
