DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The utility model provides a technical solution: a dewatering device for tailings, including a device body 1, a driving shaft 3 is rotatably connected inside the device body 1, and a filter disc 4 is evenly fixedly installed on the side wall of the driving shaft 3, and a driving motor 5 that is transmission-connected to one end of the driving shaft 3 is fixedly installed on one side wall of the device body 1, and an auxiliary support block 2 is welded and fixed on the side wall of the device body 1, and the driving motor 5 is supported and fixed by the auxiliary support block 2, and the other end of the driving shaft 3 is connected to an external vacuum device, so that the filter disc 4 is connected to the external vacuum device, and the driving motor 5 is electrically connected to an external power supply. The driving motor 5 provides power output for the driving shaft 3, so that the driving shaft 3 can drive the filter disc 4 to rotate in the inner cavity of the device body 1, and the slurry located in the device body 1 is vacuum filtered.

[0019] like Figure 3 As shown in the figure, the device body 1 is integrally formed with a feeding trough 6, a filter trough 7 and a collecting bin 8 from back to front. The feeding trough 6 is connected with the filter trough 7. The tailings slurry to be filtered is fed into the filter trough 7 through the feeding trough 6, and the slurry in the filter trough 7 is filtered through the filter disc 4 through the filter trough 7. When the filter disc 4 circulates and rotates to the collecting bin 8, the impurities attached to the side wall of the filter disc 4 are scraped off through the side wall of the collecting bin 8, thereby improving the cleanliness of the filter disc 4 during use and allowing the impurity materials to slide into the collecting bin 8 for subsequent centralized treatment.

[0020] An anti-sedimentation mechanism 9 is provided at the bottom of the filter tank 7 to prevent the slurry in the filter tank 7 from being precipitated due to poor activity, thereby affecting the filtering effect of the filter disc 4.

[0021] like Figure 3 and Figure 5 As shown in , the anti-sedimentation mechanism 9 includes a fixed pipe 91, which is embedded in the side wall of the filter tank 7. The fixed pipe 91 is connected to the assembly cavity 93 through a connecting pipe 92. The assembly cavity 93 is opened on the side wall of the inner cavity of the filter tank 7. The assembly cavity 93 is equipped with an auxiliary stirring assembly 10. The bottom of the assembly cavity 93 is fixedly connected to an L-shaped air outlet pipe 94 connected to its inner cavity, and the side wall of the air outlet pipe 94 is evenly fixedly equipped with an air outlet nozzle 95 connected to its inner cavity. Figure 2As shown in the figure, the rear side wall of the device body 1 is fixedly equipped with an air inlet pipe joint 96 connected to the fixed pipe 91, and the air inlet pipe joint 96 is connected to an external air pump. The external air pump fills the external air into the fixed pipe 91 from the air inlet pipe joint 96, and then enters the assembly cavity 93 and the air outlet pipe 94 through the connecting pipe 92, and then is ejected from the air outlet nozzle 95, so as to prevent the slurry from precipitating at the bottom of the filter tank 7, thereby affecting the filtration of the filter disc 4. Figure 5 As shown in the figure, the positions of the connecting pipe 93 and the air outlet pipe 94 are staggered with each other. When the external air passes through the assembly cavity 93 from the connecting pipe 92, the auxiliary stirring component 10 can be driven to rotate, and the auxiliary stirring component 10 is used to further stir the slurry in the filter tank 7 to prevent the slurry from precipitating in the filter tank 7.

[0022] like Figure 4 As shown in the figure, the auxiliary stirring assembly 10 includes a rotating shaft 101, which is rotatably connected to the side wall of the assembly chamber 93. The end of the rotating shaft 101 is located in the assembly chamber 93 and is welded and fixed with an impeller 102. The outer side wall of the rotating shaft 101 is evenly and fixedly connected with a stirring rod 103. When the external high-pressure gas passes through the assembly chamber 93, the cooperation between the gas and the impeller 102 drives the rotating shaft 101 to drive the stirring rod 103 to rotate, thereby auxiliary stirring of the slurry in the filter tank 7 to prevent the slurry from precipitating in the filter tank 7.

[0023] like Figure 1 and Figure 3 As shown in the figure, a discharge port 11 for discharging impurities in the collecting bin 8 to the outside is provided on the side wall of the collecting bin 8, and a closing component 12 for closing the discharge port 11 is fixedly mounted on the side wall of the device body 1, and the closing component 12 includes a hydraulic telescopic cylinder 121, and the hydraulic telescopic cylinder 121 is fixedly mounted on the left and right side walls of the device body 1, and the ends of the hydraulic telescopic cylinder 121 are fixedly connected to a closing plate 123 through a connecting frame 122, and the closing plate 123 is used to seal the discharge port 11, and the hydraulic telescopic cylinder 121 is electrically connected to an external power supply and an external controller, and the action of the output end of the hydraulic telescopic cylinder 121 is controlled by the external controller, so that the hydraulic telescopic cylinder 121 drives the closing plate 123 to move, and when the closing plate 123 is opened, the impurities in the collecting bin 8 can be discharged from the discharge port 11 to the outside.

[0024] Working principle: During the use of the device, the ore pulp to be treated is fed into the filter tank 7 from the feeding trough 6, and the filter disc 5 is driven to rotate by the driving shaft 3, so that the filter disc 5 treats the ore pulp in the filter tank 7. In the process of treating the ore pulp, the activity of the ore pulp in the filter tank 7 is enhanced by the anti-precipitation mechanism 9 located at the bottom of the filter tank 7, so as to avoid the ore pulp from precipitating in the filter tank 7, thereby affecting the treatment effect of the filter disc 5 on the ore pulp. First, the external high-pressure air is introduced into the fixed pipe 91 through the air inlet pipe joint 96, and the high-pressure air in the fixed pipe 91 enters the assembly chamber 93 through the connecting pipe 92. When the air passes through the assembly chamber 93, it drives the impeller 102 to rotate, so that the rotating shaft 101 drives the stirring rod 103 to mix and stir the ore pulp in the filter tank 7. The air after passing through the assembly chamber 93 enters the air outlet pipe 94 and is ejected into the ore pulp through the air outlet pipe nozzle 95, thereby generating bubbles, enhancing the activity of the ore pulp, and avoiding precipitation in the filter tank 7.
