Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coal slime water treatment, in particular to coal slime water concentrator equipment. Background Art
[0002] Coal slime water treatment mainly refers to the treatment technology of medium water generated during the coal sorting and processing. Coal slime water treatment has become the most extensive, largest investment, most complex and most difficult to manage process link in the entire coal preparation process.
[0003] In the treatment of coal slime water, circulating water is used as sorting and auxiliary water, and its quality is mainly reflected in the solid content, solid particle size and ash content of the circulating water. When the circulating water contains too many coal slime particles, especially high-ash and fine particles, it will seriously affect the sorting, recovery, dehydration and other operations. Using such circulating water will deteriorate the selectivity of flotation operations, and affect the air permeability of filtration during filtration and dehydration. When they adhere to the sorted products, the ash and moisture content of the products will be greatly increased. It can be seen that in order to ensure good sorting and dehydration effects, the circulating water quality must be kept clean. Clean circulating water is achieved through the clarification of coal slime water, and the clarification of coal slime water requires the use of a concentrator.
[0004] The unstable feeding of the existing concentrator can easily lead to difficulties in flocculation and sedimentation. The rising water flow rate in the concentrator is relatively fast, and the coal slime particles react with the flocculant to form flocs that cannot settle in time, resulting in a serious excess of solid content in the circulating water, affecting the balance and stability of the entire system, and thus resulting in poor clarification effect.

[0024] The utility model embodiment provides a coal slurry water concentrator device, such as Figure 1-4 As shown, it includes a concentrator body 1, an overflow weir 2 is integrally formed on the inner side wall of the concentrator body 1, and an overflow pipe 3 is fixedly connected to a side position of the outer wall of one side of the concentrator body 1 near the overflow weir 2 by bolts, a mud discharge pipe 4 is embedded in the lower position of the outer side wall of the concentrator body 1 near the side, a fixing frame 5 is fixedly connected to the lower position of the inner wall of one side of the concentrator body 1 near the overflow weir 2 by bolts, and a feed buffer barrel 6 is fixedly connected to the outer wall of the fixing frame 5 away from the concentrator body 1 by bolts, the top of the feed buffer barrel 6 is 10 cm higher than the overflow weir 2 in the concentrator body 1, a feed pipe 8 is embedded in the center of the top of the feed buffer barrel 6, and a flocculant feeding pipe 7 is embedded in the top of the feed buffer barrel 6 near the feed pipe 8. A buffer retention cover 9 is welded on the outer wall of one side of the feed buffer barrel 6, and the top of the buffer retention cover 9 is opened There is a through hole for the feeding buffer barrel 6 to pass through, and the bottom of the feeding buffer barrel 6 and the buffer retention cover 9 are both hollow cylindrical structures with bottom openings. The cross-sections of the feeding buffer barrel 6 and the buffer retention cover 9 are both circular, and the centers of the feeding buffer barrel 6, the buffer retention cover 9 and the feeding pipe 8 are on a coaxial vertical line. A first buffer disc 10, a second buffer disc 11 and a third buffer disc 12 are welded on the inner wall of one side of the feeding buffer barrel 6, and the second buffer disc 11 is located between the first buffer disc 10 and the third buffer disc 12. A drop hole 13 is opened on the outer wall of one side of the first buffer disc 10, the second buffer disc 11 and the third buffer disc 12, and a flow equalizing disc 14 is fixedly connected by bolts on the inner wall of one side of the feeding buffer barrel 6 near the position below the third buffer disc 12, and a lower hopper 15 is welded to the bottom of the flow equalizing disc 14, and the cross-section of the lower hopper 15 is an isosceles trapezoidal structure.
[0025] It should be noted that, since the existing concentrator feed is unstable and easily leads to flocculation and sedimentation difficulties, the rising water flow velocity in the concentrator is relatively fast, and the coal slime particles react with the flocculant to form flocs that cannot be settled in time, resulting in a serious excess of solid content in the circulating water, affecting the balance and stability of the entire system, and thus resulting in poor clarification effect. In this embodiment, the coal slime water and the flocculant are fully mixed during the flow process through the feed buffer barrel 6 to ensure the effect of full mixing, thereby ensuring stable feed and avoiding the problem of flocculation and sedimentation difficulties caused by uneven mixing of the coal slime water and the flocculant. The buffer retention cover 9 can control the part of the fast rising flow velocity in the concentrator body 1 inside the buffer retention cover 9 to ensure that the coal slime sedimentation outside the buffer retention cover 9 is maintained at a normal level, thereby obtaining clarified overflow water, which can be modified or promoted on old concentrators or deep cone concentrators without power devices.
[0026] Specifically, in this embodiment, this scheme mainly includes a feed buffer barrel 6 and a buffer retention cover 9. When in use, the coal slurry water enters the feed buffer barrel 6 through the feed pipe 8, and the flocculant enters the feed buffer barrel 6 through the flocculant feeding pipe 7. The coal slurry water and the flocculant fall to the first buffer disc 10 together. Under the inclined guidance of the first buffer disc 10, the coal slurry water and the flocculant are mixed together during the flow process and fall to the second buffer disc 11 through the drop hole 13. Under the inclined guidance of the second buffer disc 11, the coal slurry water and the flocculant are flipped and mixed and then fall to the third buffer through the drop hole 13. The coal slurry and flocculant are divided into four groups and discharged through the lower hopper 15. The mixture of coal slurry and flocculant enters the interior of the concentrator body 1. The mixture impacts the liquid in the concentrator body 1. The liquid is impacted to accelerate the flow rate. The buffer retention cover 9 controls the part of the rising flow rate in the concentrator body 1 within the buffer retention cover 9, ensuring that the coal slurry sedimentation outside the buffer retention cover 9 is maintained at a normal level, thereby obtaining clarified overflow water. The clarified water overflows to the overflow weir 2 and is discharged through the overflow pipe 3.

[0028] In this embodiment, the first buffer disc 10, the second buffer disc 11 and the third buffer disc 12 can achieve full mixing of the coal slurry and the flocculant during the flow process, thereby ensuring a full mixing effect.
[0029] In a further preferred embodiment of the present invention, Figure 2 As shown, a through hole communicating with the lower hopper 15 is provided at the top of the flow balancing plate 14 . There are four lower hoppers 15 in total, and the four lower hoppers 15 are symmetrically arranged at the bottom of the flow balancing plate 14 .
[0030] In this embodiment, by providing four lower hoppers 15 , the falling coal slurry water and flocculant mixture can be divided into four parts, thereby reducing the impact during the falling process and further reducing the liquid flow rate in the concentrator body 1 .
