[0002] Rapid sedimentation of coal slime particles refers to a technology that accelerates the sedimentation process of coal slime particles in water through a series of physical, chemical or electrochemical methods, thereby improving the efficiency of coal slime water treatment. This technology aims to solve the problems of slow sedimentation rate, long treatment time and low resource utilization in traditional sedimentation methods.

[0003] The existing method of settling coal slime particles is usually to introduce specific ions into the coal slime water to compress the double electrical layer on the surface of the coal slime particles, making the coal slime particles easy to agglomerate, and then to allow the coal slime particles to settle naturally under the action of gravity. However, the natural sedimentation method is too slow and cannot achieve rapid sedimentation, resulting in low sedimentation efficiency of coal slime particles and is relatively inconvenient.

[0004] Therefore, it is necessary to design a coal slime particle rapid sedimentation device for coal slime water recovery that can pressurize and sediment the coal slime water while stirring it, accelerate the chemical reaction in the ion regulation process, facilitate the rapid sedimentation of the coal slime particles, and improve the sedimentation efficiency.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] A coal slime particle rapid sedimentation device for coal slime water recovery, such as Figure 1-Figure 3 As shown, it includes a base 1, a support frame 2, a sedimentation mechanism 3 and a stirring mechanism 4. The support frame 2 is connected to the upper side of the base 1. The upper part of the base 1 is provided with a sedimentation mechanism 3 capable of pressurizing and sedimenting the coal slurry water. The sedimentation mechanism 3 is provided with a stirring mechanism 4 capable of stirring the coal slurry water.

[0028] like Figure 1 , Figure 2 and Figure 4As shown, the sedimentation mechanism 3 includes a sedimentation tank 31, an upper end cover 32, a sedimentation plate 33, a feeding pipe 34, a valve switch 35, a cylinder 36 and a piston 37. The upper part of the support frame 2 is connected to the sedimentation tank 31, the upper part of the sedimentation tank 31 is clamped with the upper end cover 32, the right part of the upper end cover 32 is provided with a buckle for easy clamping, and the inner side of the lower part of the upper end cover 32 is provided with a sealing gasket for enhancing the sealing performance. The lower part of the sedimentation tank 31 is clamped with the sedimentation plate 33, the right side of the middle part of the sedimentation tank 31 is connected to the feeding pipe 34, the right side of the feeding pipe 34 is provided with a flange for easy docking, the feeding pipe 34 is connected with a valve switch 35, the upper side of the upper end cover 32 is connected to the cylinder 36, the telescopic end of the cylinder 36 is connected to the piston 37, and the piston 37 is in contact with the inside of the sedimentation tank 31.

[0029] like Figure 2 and Figure 5 As shown, it also includes a stirring mechanism 4, which includes a top frame 41, a screw rod 42 and a rotating frame 43. The top frame 41 is connected to the lower middle side of the piston 37, the screw rod 42 is connected to the upper middle side of the sedimentation plate 33, the rotating frame 43 is threadedly connected to the screw rod 42, and the rotating frame 43 is rotatably connected to the top frame 41.

[0030] When using the device, firstly, the base 1 is placed in the area where the coal slime particles are rapidly settling, and then the coal slime water is poured into the settling tank 31, and then specific ions are introduced into the coal slime water to change the charge state on the surface of the coal slime particles, and then the upper end cover 32 is clamped on the settling tank 31 through a buckle, and then the external recovery and processing device is connected through a flange, and then the cylinder 36 is started to drive the piston 37 to move downward, so that the pressure in the settling tank 31 is increased, and the settling of the coal slime particles is accelerated. When the piston 37 moves downward, it drives the top frame 41 to move downward, so that the rotating frame 43 moves downward and rotates under the action of the thread, and the coal slime water is stirred by the rotation of the rotating frame 43. Stirring helps to evenly disperse the added ions in the entire coal slime water, so that the coal slime water can be pressurized and precipitated while being stirred, accelerating the chemical reaction in the ion regulation process, facilitating the rapid sedimentation of the coal slime particles, and improving the sedimentation efficiency. Then, the valve switch 35 is opened, and the piston 37 is moved downward by controlling the cylinder 36, so that the water is discharged to the recovery and processing device through the feeding pipe 34, so that the coal slime particles are settled on the sedimentation plate 33, and then the upper end cover 32 is opened from the sedimentation tank 31, so that the piston 37, the top frame 41, the screw rod 42, the rotating frame 43 and the sedimentation plate 33 are taken out, and then the coal slime particles on the sedimentation plate 33 are recovered.

[0031] like Figure 2 and Figure 6As shown, a reinforcing mechanism 5 is also included, which includes a fixed block 51, a telescopic rod 52, a lower pressure ring 53 and a spring 54.

[0032] When the enhancement mechanism 5 of the device is used, the coal slurry water can be assisted in stirring. When the piston 37 moves downward, the piston 37 contacts and squeezes the lower pressure ring 53, driving the lower pressure ring 53 to move downward, causing the telescopic end of the telescopic rod 52 to contract, and the spring 54 is squeezed and contracted. When the piston 37 moves upward, the spring 54 recovers, driving the lower pressure ring 53 to move upward, and the telescopic end of the telescopic rod 52 extends. The coal slurry water is assisted in stirring by the up and down movement of the lower pressure ring 53. At the same time, the material stuck in the sedimentation tank 31 is scraped off by the lower pressure ring 53, so that the coal slurry water can be assisted in stirring while the material stuck in the sedimentation tank 31 can be scraped off, thereby improving the stirring effect and efficiency.

[0033] like Figure 2 and Figure 6 As shown, a cleaning mechanism 6 is also included, which includes a connecting member 61, a scraper 62 and a connecting rod 63. The middle part of the upper end cover 32 is rotatably connected to the connecting member 61, the right side of the connecting member 61 is connected to the scraper 62, and the upper middle side of the scraper 62 is connected to the connecting rod 63. A gripping ball is provided on the connecting rod 63 for easy gripping.

[0034] When the cleaning mechanism 6 of the device is used, the coal slime particles on the sedimentation tray 33 can be conveniently scraped off. After the sedimentation tray 33 is taken out of the sedimentation tank 31, the gripping ball on the connecting rod 63 can be held and rotated to drive the connecting member 61 to rotate, so that the scraper 62 rotates, and the coal slime particles on the sedimentation tray 33 are scraped off by the scraper 62, so that the coal slime particles on the sedimentation tray 33 can be conveniently scraped off, the operation is simple, and the coal slime particles are easy to recover.
