Description

Technical Field

[0001] The utility model relates to the technical field of tailings sedimentation, in particular to an efficient tailings sedimentation device. Background Technique

[0002] The tailings sedimentation device is mainly used for treating and storing tailings generated during the ore processing process. The device is usually equipped with filtration and separation equipment for treating solid particles and moisture in the tailings. These equipment include centrifuges, filters, sedimentation tanks, etc., which help to reduce the moisture content in the tailings and improve the stability of solid particles for safer storage and treatment of tailings. At the same time, since tailings usually contain a large amount of moisture and chemical agent residues, facilities such as sedimentation tanks, flocculation tanks, filtration systems, and chemical treatment devices must be used to clean and treat this water to ensure safe release into the environment or reuse. However, at present, after the tailings device uses a flocculant to sediment the ore slurry, the flocs discharged from the tailings device still contain a large amount of moisture, and this moisture will be discharged together with the flocs in the traditional treatment method, and it is very difficult to be recovered and reused. Content of the Utility Model

[0003] The purpose of the utility model is to provide an efficient tailings sedimentation device. A sewage discharge pipe extending obliquely upward is arranged at the bottom end of the sedimentation tank. The auger roller in the sewage discharge pipe is used to convey the flocs in the sedimentation tank obliquely upward. During the conveying process, the filter membrane on the lower surface of the sewage discharge pipe separates the flocs and the slurry. The separated slurry is received and recycled by the water receiving tank to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An efficient tailings sedimentation device, including a foot support column and a sedimentation tank fixed at the top end of the foot support column. A lifting pipe extending obliquely upward is installed at the bottom end of the sedimentation tank, and a sewage discharge pipe extending downward is installed at the end of the lifting pipe away from the sedimentation tank.

A rectangular notch part is arranged on the lower surface of the lifting pipe, and a filter membrane is installed inside the rectangular notch part. A belt drive mechanism for driving the auger roller to rotate is installed on the outer wall of one side of the sedimentation tank.

[0005] Preferably, a liquid inlet pipe is installed on the outer wall of the sedimentation tank away from the lifting pipe.

[0006] Preferably, a multi-blade mixing paddle parallel to the extension direction of the lifting pipe is actively installed on the inner wall of one side of the sedimentation tank.

[0008] Preferably, the multi-blade mixing paddle comprises a main shaft rotatably mounted on an inner wall of one side of the settling box, and six right-angled trapezoidal blades equidistantly mounted on an outer wall of the main shaft.

[0009] Preferably, a cover plate is bolted to the upper surface of the riser.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the tailings efficient sedimentation device is provided with a lifting pipe, a filter membrane and other structures that cooperate with each other. The device uses gravity to enable flocculants and slurry in the tailings to be transported obliquely upward along the lifting pipe, and the inclination angle and length of the lifting pipe are optimized according to the flow characteristics and separation requirements of the tailings, ensuring that the slurry is effectively separated during the transportation process, thereby maximizing the recovery and reuse of water in the tailings.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Please refer to Figures 1-5 As an embodiment provided by the utility model, a highly efficient tailings sedimentation device includes a foot support column 1 and a sedimentation tank 2 fixed at the top of the foot support column 1. A lifting pipe 9 extending obliquely upward is installed at the bottom end of the sedimentation tank 2. A cover plate 904 is bolted to the upper surface of the lifting pipe 9, and a sewage discharge pipe 901 extending downward is installed at one end of the lifting pipe 9 away from the sedimentation tank 2. The cover plate 904 serves to block the upper opening of the lifting pipe 9;

[0019] A water receiving tank 7 is arranged below the lifting pipe 9, and a switch valve 8 is installed on the outer wall of one side of the lifting pipe 9. The staff can open the switch valve 8 to discharge the slurry recovered in the water receiving tank 7 for subsequent use;

[0020] A screw roller 10 is rotatably installed inside the lifting pipe 9. A rectangular notch 902 is provided on the lower surface of the lifting pipe 9, and a filter membrane 903 is installed inside the rectangular notch 902. The filter membrane 903 can effectively block larger solid particles, causing them to deposit at the bottom of the lifting pipe 9, while the slurry can pass through the filter membrane 903 and be received and recycled by the water receiving tank 7, ensuring the maximum separation of solid particles during discharge. A belt drive mechanism 6 for driving the screw roller 10 to rotate is installed on the outer wall of one side of the sedimentation tank 2;

[0021] The belt drive mechanism 6 drives the screw roller 10 to rotate. The screw roller 10 is located inside the lifting pipe 9, and it stirs and pushes the passing tailings to increase the separation efficiency of the slurry and solid particles;

[0022] A liquid inlet pipe 3 is installed on the outer wall of one side of the sedimentation tank 2 away from the lifting pipe 9. The multi - leaf mixing paddle 4 includes a main shaft rotatably installed on the inner wall of one side of the sedimentation tank 2 and six right - angled trapezoidal blades equidistantly installed on the outer wall of the main shaft;

[0023] A multi - leaf mixing paddle 4 parallel to the extension direction of the lifting pipe 9 is actively installed on the inner wall of one side of the sedimentation tank 2. The belt drive mechanism 6 includes a right - angled seat 5 fixed on the outer wall of one side of the sedimentation tank 2 and a stepping motor installed on the outer wall of one side of the right - angled seat 5. The output end of the stepping motor is installed with a crawler drive structure for driving the multi - leaf mixing paddle 4 and the screw roller 10 to rotate;

[0024] The belt drive mechanism 6 adopts a stepping motor and a crawler drive structure, enabling the multi - leaf mixing paddle 4 and the screw roller 10 to operate stably for a long time. When the belt drive mechanism 6 works, a part of its rotating power is transmitted to the multi - leaf mixing paddle 4, enabling the multi - leaf mixing paddle 4 to rotate at an appropriate speed and direction while working in coordination with the screw roller 10, ensuring that every part of the tailings can be evenly mixed and enter the sedimentation process, avoiding overly dense or uneven sedimentation phenomena, thereby optimizing the sedimentation effect.

[0025] When the embodiment of the present application is in use, first, the staff discharges the tailings ore slurry to be sedimented into the inside of the sedimentation tank 2. Subsequently, a flocculant suitable for the properties of the tailings ore slurry is selected and put into the inside of the sedimentation tank 2 to improve the sedimentation rate of solid particles. After waiting for a period of time, the flocculant reacts with the tailings ore slurry to form flocs. During this process, the formed flocs will actively precipitate at the bottom of the foot support column 1, and as the flocs increase, they will enter the riser pipe 9. At this time, the staff starts the belt drive mechanism 6 to work, and the belt drive mechanism 6 drives the multi-blade mixing paddle 4 and the auger roller 10 to rotate slowly. During this process, the multi-blade mixing paddle 4 serves the purpose of further mixing the upper-layer tailings ore slurry and the flocculant, while the auger roller 10 actively rotates and conveys the flocs precipitated inside the riser pipe 9, so that the precipitated flocs are conveyed along the obliquely upward extension direction of the riser pipe 9. Since the filter membrane 903 and the rectangular notch 902 are higher than the liquid level height of the foot support column 1, when the flocs and the tailings ore slurry are conveyed upward, the liquid tailings ore slurry will flow downward under the action of gravity and return to the foot support column 1 again, while the flocs can be actively discharged through the sewage discharge pipe 901. During this process, a part of the tailings ore slurry carried by the flocs will pass through the filter membrane 903 and be discharged into the water receiving tank 7 to achieve the purpose of separating the tailings ore slurry and the flocs, so that a part of the tailings ore slurry in the flocs can be separated. This device utilizes gravity to enable the flocs and the slurry in the tailings to be conveyed obliquely upward along the riser pipe 9, and the inclination angle and length of the riser pipe 9 are optimized according to the flow characteristics and separation requirements of the tailings to ensure that the slurry is effectively separated during the conveying process, so as to maximize the recovery and reuse of the water in the tailings.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
