The fixing ring 2 is installed on the outer surface of the settling shell 1, providing a fixing point for the support rod 3 installed at its bottom. Four groups of support rods 3 are installed at the bottom of the fixing ring 2. The support rod 3 is installed at the bottom of the fixing ring 2, providing a fixing point for the flange 4 installed at its bottom. The support force conducted to its interior through the external plane provides support for the whole device. The flange 4 is installed at the bottom of the support rod 3. When it is necessary to fix the settling structure, the external bolt can be inserted into the interior of the flange 4 through the external control component and the external bolt can be inserted into the interior of the external fixing plane to complete the fixation of the whole device. The output pipe 10 is installed through the bottom of the settling shell 1. The output pipe 10 is installed at the bottom of the settling shell 1. When the interior of the output pipe 10 is connected, under the action of gravity, the settled pulp is output to the external environment, and at the same time provides a fixing point for the second electric throttle valve 11 installed through its outer surface. The second electric throttle valve 11 is installed through the outer surface of the output pipe 10. When it is necessary to output the settled pulp, the electric energy can be delivered to the interior of the second electric throttle valve 11 through the external control component to drive the second electric throttle valve 11 to open and drive the interior of the output pipe 10 to be connected. The intercepting net 12 is installed on the inner side of the settling shell 1 through a connecting ring. The intercepting net 12 is installed on the inner side of the settling shell 1 to prevent large-particle gravel and residues in the pulp from entering the settled pulp. The first connecting bolts 13 are installed on both sides of the settling shell 1. The first connecting bolt 13 is installed at the bottom of the settling shell 1, providing a fixing point for the lifting rod 14 installed at its top. The lifting rod 14 is installed at the top of the first connecting bolt 13. The lifting rod 14 is installed at the top of the first connecting bolt 13, providing a fixing point for the gear reducer 15 installed at its tail end. The gear reducer 15 is installed at the tail ends of the two lifting rods 14. When the rotational force is delivered to the interior of the gear reducer 15 through the motor 16, the gear reducer 15 delivers the rotational force to the interior of the transmission rod 17. The motor 16 is installed at the top of the gear reducer 15. When it is necessary to fully mix the pulp and additives in the settling shell 1, the electric energy can be delivered to the interior of the motor 16 through the external control component. At this time, the motor 16 delivers the rotational force to the interior of the gear reducer 15 through electromagnetic effect. The output end of the gear reducer 15 is installed with a transmission rod 17, and the tail end of the transmission rod 17 extends below the intercepting net 12. When the rotational force is delivered to the interior of the transmission rod 17 through the gear reducer 15, the transmission rod 17 drives the stirring head 18 installed at its tail end to rotate. The stirring head 18 is installed at the tail end of the transmission rod 17. The stirring head 18 is installed at the tail end of the transmission rod 17 and rotates under the drive of the transmission rod 17.Stir the pulp and additives to drive the full mixing of the pulp and additives. A second connecting bolt 19 is installed inside the settling shell 1. The installation of the second connecting bolt 19 inside the settling shell 1 provides a fixed point for the electric telescopic rod 20 whose top penetrates the settling shell 1. The electric telescopic rod 20 is installed through the top of the second connecting bolt 19. When it is necessary to extract the settled clear water, electric energy can be transmitted to the inside of the electric telescopic rod 20 via an external control component. At this time, the electric telescopic rod 20 drives the extraction pipe 22 connected to its tail end to move downward, driving the tail end of the extraction pipe 22 to contact the pulp clear water. A delivery pump 21 is installed on the back of the settling shell 1. When it is necessary to extract the clear water in the pulp, electric energy can be transmitted to the inside of the delivery pump 21 via an external control component. At this time, the delivery pump 21 generates suction inside the extraction pipe 22 and conveys the extracted clear water to the inside of the drain pipe 23. The output end of the delivery pump 21 is installed with the extraction pipe 22, and the tail end of the extraction pipe 22 passes through the second connecting bolt 19 and is connected to the electric telescopic rod 20. The extraction pipe 22 contacts the clear water at the top of the pulp under the drive of the electric telescopic rod 20, and under the suction of the delivery pump 21, the clear water is conveyed into the delivery pump 21. The output end of the delivery pump 21 is installed with the drain pipe 23. When the clear water is conveyed into the inside of the drain pipe 23 under the action of the delivery pump 21, the drain pipe 23 conveys the clear water to the external environment, thereby completing the output of the clear water.,

[0022] Working principle: First, inject the pulp into the inside of the settling shell 1, and then inject the additives into the inside of the settling shell 1 via the weighing hopper 7 and the delivery pipe 8. At this time, via an external control component, electric energy is transmitted to the inside of the motor 16. At this time, the motor 16 transmits the rotational force to the inside of the gear reducer 15 via the electromagnetic effect. The gear reducer 15 transmits the rotational force to the inside of the transmission rod 17. The transmission rod 17 drives the stirring head 18 installed at its tail end to rotate. The stirring head 18 stirs the pulp and additives to drive the full mixing of the pulp and additives. Then, let it stand still for a long time to separate the pulp sediment and the water body. Then, via an external control component, electric energy is transmitted to the inside of the electric telescopic rod 20. At this time, the electric telescopic rod 20 drives the extraction pipe 22 connected to its tail end to move downward, driving the tail end of the extraction pipe 22 to contact the pulp clear water. The delivery pump 21 generates suction inside the extraction pipe 22. Under the suction of the delivery pump 21, the extraction pipe 22 conveys the clear water into the delivery pump 21. The delivery pump 21 conveys the extracted clear water to the inside of the drain pipe 23. The drain pipe 23 conveys the clear water to the external environment, thereby completing the output of the clear water. Then, via an external control component, electric energy is transmitted to the inside of the second electric throttle valve 11 to drive the second electric throttle valve 11 to open and connect the inside of the output pipe 10. Under the action of gravity, the output pipe 10 outputs the settled pulp to the external environment, completing the sedimentation separation of the bauxite pulp.

The fixing frame 5 is installed on the front of the sedimentation shell 1. The fixing frame 5 is installed on the front of the sedimentation shell 1 to provide a fixing point for the pressure weighing sensor 6 installed on its top. Four groups of pressure weighing sensors 6 are installed on the top of the fixing frame 5. The pressure weighing sensors 6 are installed on the top of the fixing frame 5 to detect the weight data inside the weighing hopper 7 and transmit the detected data to the inside of an external control component. A weighing hopper 7 is installed on the top of the four groups of pressure weighing sensors 6. Before using the device, additives are injected into the inside of the weighing hopper 7. At this time, the weighing hopper 7 provides a temporary storage space for the additives. A delivery pipe 8 is installed through the bottom of the weighing hopper 7, and the tail end of the delivery pipe 8 extends below the fixing frame 5. The delivery pipe 8 is installed at the bottom of the weighing hopper 7. After the inside of the delivery pipe 8 is connected, under the action of gravity, the delivery pipe 8 continuously delivers the additives to the inside of the sedimentation shell 1. A first electric throttle valve 9 is installed through the outer surface of the delivery pipe 8. When the additives inside the weighing hopper 7 reach the specified weight, electric energy can be transmitted to the inside of the first electric throttle valve 9 via an external control component to open and drive the inside of the delivery pipe 8 to be connected.
