Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mineral processing measurement and inspection equipment, and in particular relates to a large-scale flotation machine sampling device. Background Art
[0002] Flotation is a mineral processing technology that utilizes the physical and chemical properties of the surface of mineral particles to make the target mineral particles hydrophobically adhere to bubbles and float up with the bubbles to form foam products, thereby separating the target mineral from other minerals. The main production equipment of the flotation process is the flotation machine. With the increase of the processing scale of the ore dressing plant, the volume of a single tank is greater than 100m 3 Flotation equipment has been widely used in industry. At present, the world's largest flotation machine has a capacity of 320m 3 Large-scale flotation machines can significantly improve ore recovery and efficiency during the mineral processing process, thereby achieving the goal of saving resources and reducing costs. However, as the equipment gradually becomes larger, the difficulty of flotation slurry sampling increases. Conventional sampling tools are difficult to operate, and foam products on the surface of the slurry are often collected during the sampling process, resulting in a high grade of the collected samples and a weak representativeness of the samples, which in turn affects the accuracy of the flotation indicators.

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.
[0016] like Figure 1 As shown, a large-scale flotation machine sampling device comprises an air conveying pipe 1, a slurry diversion main pipe 2, an air flow baffle 4, a slurry diversion branch pipe 5, and a sampling storage tank 6; wherein the air conveying pipe 1 penetrates into the slurry diversion main pipe 2, the air flow baffle 4 is fixed to the bottom of the air conveying pipe 1 located in the slurry diversion pipe 2 through a connecting rod 3, a slurry diversion branch pipe 5 connected to the interior of the slurry diversion main pipe 2 is welded to the top side thereof, and a sampling storage tank 6 is placed below the slurry diversion branch pipe 5.
[0017] The slurry diversion main pipe 2 is sealed at the top and open at the bottom.
[0018] The junction between the air conveying pipe 1 and the slurry diversion main pipe 2 is sealed, and the junction between the top side of the slurry diversion main pipe 2 and the slurry diversion branch pipe 5 is also sealed.
[0019] The air delivery pipe 1 is a DN20-DN50 steel pipe or iron pipe.
[0020] The slurry diversion main pipe 2 is a DN50-DN100 steel pipe or iron pipe.
[0021] The slurry diversion branch pipe 5 is a DN20-DN50 steel pipe or iron pipe.
[0022] The connecting rod 3 is a common steel bar with a diameter of 10-20 mm; the air flow baffle 4 is a steel plate with a thickness of 5-10 mm; and the sampling tank 6 is a plastic or iron barrel.
[0023] The longitudinal height of the device of the present invention can be achieved by changing the length of the slurry guide pipe 2 according to the specifications of the flotation machine; the sampling storage tank 6 can be set to different volumes according to the amount of samples to be collected.
[0024] When sampling, the sampling tank 6 is placed outside the flotation machine, and the slurry diversion main pipe 2 is extended into the liquid inside the flotation machine. A blower or an air compressor is used to provide compressed air. After the compressed air enters the air delivery pipe 1, it collides with the air flow baffle 4 and enters the slurry diversion main pipe 2, so that a negative pressure environment is formed in the slurry diversion main pipe 2, thereby driving the slurry into the slurry diversion main pipe 2, and the slurry enters the sampling storage tank 6 through the diversion pipe 5. At this time, the slurry sampling is realized, and the sampling amount can be achieved by controlling the ventilation time.
[0025] The slurry diversion branch pipe 5 belongs to the slurry conveying pipeline, and its length can be adjusted according to the on-site conditions to ensure that the slurry coming out of the slurry diversion branch pipe 5 can enter the sampling storage tank 6.
