Description

Technical Field

[0001] This utility model relates to the field of slurry treatment technology, and in particular to a tailings deep cone thickening device. Background Technology

[0002] Tailings deep cone thickener is a high-efficiency thickening and dewatering equipment used for mine tailings treatment. It mainly increases the concentration of tailings slurry by forming flocs under the action of flocculants, and the particles quickly settle to the bottom of the cone, thereby achieving solid-liquid separation and facilitating subsequent comprehensive utilization.

[0003] A search revealed Chinese patent publication number CN119425168A, which discloses a tailings deep cone thickening device and its usage method. This patent connects to external clean water through an inlet pipe, and a water pump draws clean water into the water tank through an outlet pipe. Simultaneously, a drive motor drives a rotating rod and a first transmission gear to rotate, causing a second transmission gear to drive a cleaning ring downwards through a threaded rod. At the same time, a spray pipe sprays clean water onto the inner wall of the device for cleaning. This device has certain problems: the cleaning ring is of a fixed size, and only clean water flows from the water tank to the inner wall of the cylinder, which cannot effectively clean stubborn stains on the conical inner wall.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a tailings deep cone thickening device includes a support 101, a cylinder 102 on the support 101, a rotating shaft 302 coaxially rotatably connected inside the cylinder 102, and a plurality of stirring plates 401 fixed at the lower end of the rotating shaft 302.

[0027] Multiple agitator plates 401 are evenly distributed in a spiral shape around the circumference of the rotating shaft 302. The agitator plates 401 abut against the inner wall of the cylinder 102. Multiple fixing rods 402 are fixedly connected to the rotating shaft 302, and are evenly distributed around the circumference of the rotating shaft 302. A scraper 403 is provided at the end of the fixing rod 402 away from the rotating shaft 302. The scraper 403 is inclined in the same direction as the agitator plates 401. A locking knob 404 is threadedly connected between the scraper 403 and the fixing rod 402. Multiple rake frames 405 are fixedly connected to the rotating shaft 302, and the rake frames 405 are located above the fixing rods 402. In use, the tailings slurry is poured into the cylinder 102, flocculant is added into the cylinder 102, and then... The drive shaft 302 rotates, causing the agitator plate 401 and the rake frame 405 to rotate. The agitator plate 401 stirs the slurry at the bottom of the cylinder 102 upwards, while the scraper plate 403 scrapes off the slurry near the inner wall of the cylinder 102, ensuring that the slurry comes into full contact with the flocculant. Then, the drive shaft 302 stops rotating and the supernatant is extracted. The drive shaft 302 is then reversed, causing the slurry sediment to be discharged from the bottom of the cylinder 102 as the agitator plate 401 rotates. At the same time, the agitator plate 401 and the scraper plate 403 scrape off the residual sediment on the inner wall of the cylinder 102, preventing stubborn stains from adhering to the inner wall of the cylinder 102. After use, the scraper plate 403 can be removed and cleaned by rotating the locking knob 404.

[0028] A fixing frame 103 is fixed at the upper end of the cylinder 102, and a power motor 301 is fixedly installed at the upper end of the fixing frame 103. The output shaft of the power motor 301 is fixedly connected to the rotating shaft 302, and the power motor 301 drives the rotating shaft 302 to rotate.

[0029] A water pumping pipe 501 is fixedly connected to one side of the fixed frame 103. A telescopic water pipe 502 is slidably connected to the lower end of the water pumping pipe 501. A drive mechanism is provided on the telescopic water pipe 502.

[0030] The drive mechanism includes a mounting block 601, which is fixed to the lower end of the telescopic water pipe 502. An electric telescopic rod 602 is fixed between the mounting block 601 and the fixing frame 103. The electric telescopic rod 602 drives the mounting block 601 to move the telescopic water pipe 502 downward to contact the supernatant.

[0031] A door 201 is hinged to the front end of the cylinder 102. A connecting block 202 is fixed to the side of the door 201 away from its hinge axis. A fixing knob 203 is threadedly connected between the connecting block 202 and the cylinder 102. After a period of use, the fixing knob 203 is turned to open the door 201, thereby cleaning the inside of the cylinder 102.

[0032] The fixing frame 103 is U-shaped with the opening facing downwards, and positioning knobs are threadedly connected between the fixing frame 103 and the cylinder 102 on both sides.

[0033] A discharge pipe is fixed at the lower end of the cylinder 102, and a discharge valve 7 is fixedly installed on the discharge pipe. When the discharge valve 7 is opened, the slurry sediment is discharged from the discharge pipe.

[0034] Working principle: During use, tailings slurry is poured into the cylinder 102, flocculant is added, and then the motor 301 drives the rotating shaft 302 to rotate, which in turn drives the agitator 401 and the rake frame 405 to rotate. The agitator 401 stirs the slurry at the bottom of the cylinder 102 upwards, and the rake frame 405 horizontally stirs the slurry that has been turned up. At the same time, the scraper 403 scrapes the slurry near the inner wall of the cylinder 102, ensuring that the slurry and flocculant are in full contact. Then, the rotating shaft 302 stops rotating, and the electric telescopic rod 602 is driven to install... Block 601 drives the telescopic water pipe 502 to move downwards to extract the supernatant. Then, it drives the rotating shaft 302 to reverse and open the discharge valve 7, so that the slurry sediment is discharged from the lower end of the cylinder 102 as the stirring plate 401 rotates. At the same time, the stirring plate 401 and the scraper 403 scrape off the residual sediment on the inner wall of the cylinder 102 to prevent stubborn stains from adhering to the inner wall of the cylinder 102. After a period of use, turn the fixing knob 203 to open the bin door 201 to clean the inside of the cylinder 102. The locking knob 404 can be turned to remove the scraper 403 for cleaning.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
