Description

Technical Field

[0001] This utility model relates to the field of mine tailings backfilling technology, and in particular to a whole tailings dewatering device. Background Technology

[0002] Mine backfill materials typically use tailings cemented backfill materials, which are prepared by dewatering all tailings and then adding activators. Dewatering the tailings is a crucial step; only effective dewatering can increase the slurry concentration and enhance its fluidity and stability.

[0003] Existing dewatering devices, such as the non-powered tailings thickening and dewatering device disclosed in patent publication number CN106039783A, are equipped with an upper chamber. After the tailings enter the upper chamber, they settle and are dewatered under their own gravity. Another example is a two-stage continuous, rapid, and deep dewatering system for tailings slurry disclosed in existing patent publication number CN113024080A, which is equipped with a central mixing well. After the tailings enter the central mixing well, they are dewatered through settling. Both of these methods use static dewatering. Before dewatering, the tailings are in the state of slurry. If only static dewatering is used, the dewatering time will be long and the dewatering effect will be poor. Utility Model Content

[0004] The purpose of this invention is to provide a tailings dewatering device that improves the dewatering effect and shortens the dewatering time.

[0005] The technical solution of this utility model is: a whole tailings dewatering device, including a shell with an A end and a B end. The A end of the shell is provided with a feeding end, and the B end of the shell is provided with a discharging end. The shell is provided with a conveying mechanism connected to the feeding end and the discharging end. The conveying mechanism includes a first pulley rotatably disposed at the A end of the shell, a second pulley rotatably disposed at the B end of the shell, a drive mechanism mounted on the shell, a drive wheel mounted on the power output end of the drive mechanism, and an ultrasonic broadband liquid-solid separation strip wound around the first pulley, the second pulley and the drive wheel; a guide plate is provided below the conveying mechanism.

[0006] In the above scheme, a conveying mechanism with a drive mechanism, pulleys, and an ultrasonic broadband liquid-solid separation belt is set up. The operation of the ultrasonic broadband liquid-solid separation belt dynamically dewaters the tailings placed on it, facilitating rapid dewatering of the tailings in slurry form. It also prevents the tailings from accumulating in one place, thus avoiding delays in dewatering, effectively shortening the dewatering time and improving the dewatering effect. The ultrasonic broadband liquid-solid separation belt is a custom-made component with screen holes.

[0007] Preferably, the ultrasonic broadband liquid-solid separation strip has a slope on the side facing the feed end, and the slope forms an angle α with the horizontal plane, where the angle α is an acute angle; the acute angle is 5°~45°. This extends the residence time of the tailings on the ultrasonic broadband liquid-solid separation strip during the upward process, further improving the dewatering effect.

[0008] Preferably, the drive wheel is a cam. The cam design ensures that the ultrasonic broadband liquid-solid separation strip vibrates during operation, further improving the dehydration effect.

[0009] Preferably, the driving mechanism includes a first motor disposed on top and a second motor disposed on the bottom. The driving wheel is disposed on the motor shafts of both the first motor and the second motor. The ultrasonic broadband liquid-solid separation strip between the first motor and the first pulley is disposed towards the feed end, and the ultrasonic broadband liquid-solid separation strip between the second motor and the second pulley is disposed near the discharge end.

[0010] Preferably, the housing contains at least one high-frequency ultrasonic generator adapted to the ultrasonic broadband liquid-solid separation strip. When the high-frequency ultrasonic generator is working, it ensures that the ultrasonic broadband liquid-solid separation strip produces a shaking effect during operation, further improving the dehydration effect.

[0011] Preferably, the discharge end of the shell is provided with a guide plate, which is connected to the shell and the guide bottom plate.

[0012] Preferably, a discharge pipe is connected to the guide plate, the discharge pipe is located near end A, and the guide plate is an inclined plate that slopes towards the discharge pipe. In this way, the screened material (mainly water) can be quickly discharged from the discharge pipe along the inclined plate.

[0013] Preferably, the guide plate is provided with a baffle, which is located on the side of the discharge pipe and close to end A.

[0014] Preferably, the cross-section of the guide plate is V-shaped.

[0015] Preferably, the housing is mounted on the frame via a support frame.

[0016] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0017] I. This utility model is equipped with a conveying mechanism consisting of a drive mechanism, a pulley, and an ultrasonic broadband liquid-solid separation belt. Through the operation of the ultrasonic broadband liquid-solid separation belt, the tailings placed on it are dynamically dewatered, which is conducive to the rapid dewatering of the tailings in the mud state. At the same time, it also avoids the tailings from accumulating in one place, which would delay dewatering, effectively shortening the dewatering time and improving the dewatering effect.

[0018] II. This utility model designs the drive wheel as a cam structure, so that the ultrasonic broadband liquid-solid separation strip contacts the large-diameter surface and the small-diameter surface on the cam respectively, thereby changing its position and generating vibration, thus improving the dehydration effect through another dynamic dehydration method.

[0019] Third, the ultrasonic broadband liquid-solid separation strip has an upward slope on one side, which can slow down the movement speed of the tailings in the mud state. This not only achieves sufficient dewatering time but also meets the production cycle and facilitates seamless connection to the next process.

[0020] IV. This utility model is equipped with a high-frequency ultrasonic generator adapted to the ultrasonic broadband liquid-solid separation strip. The high-frequency ultrasonic generator is used to assist in the dewatering of the tailings, which effectively increases the concentration of the tailings (e.g., the concentration is 26-75% when feeding and can reach 73-85% after dewatering).

The ultrasonic broadband liquid-solid separation strip 44 has multiple sieve holes.

[0030] The drive mechanism 41 includes a first motor 411 mounted on top and a second motor 412 mounted on the bottom. A mounting base 10 is fixed between the two side plates 101, and the first motor 411 and the second motor 412 are mounted on the mounting base 10. The drive wheel 45 is mounted on the motor shafts of both the first motor 411 and the second motor 412. The ultrasonic broadband liquid-solid separation strip 44 between the first motor 411 and the first pulley 42 forms a first section, which faces the feed end 103. The first section of the ultrasonic broadband liquid-solid separation strip 44 has an upward slope. The slope forms an angle α with the horizontal plane, and the angle α is an acute angle, such as 6-15°. The tailings from the feed end 103 first fall onto this section of the ultrasonic broadband liquid-solid separation strip 44. At least one high-frequency ultrasonic generator 5 can be correspondingly mounted on the first section of the ultrasonic broadband liquid-solid separation strip 44. The high-frequency ultrasonic generator 5 can be mounted on the housing 1 or on one of the connecting columns 102. The high-frequency ultrasonic generator 5 emits high-frequency ultrasound to the ultrasonic broadband liquid-solid separation strip 44, which facilitates water removal. Its ultrasonic frequency is 2000-100000Hz, with an enhanced broadband frequency of 10-500 r / s, enabling ultrasound-assisted dehydration. The high-frequency ultrasonic generator 5 can be custom-designed and outsourced based on the high-frequency ultrasonic working principle. The number of high-frequency ultrasonic generators 5 can be selected according to actual needs.

[0031] The ultrasonic broadband liquid-solid separation strip 44 between the second motor 412 and the second pulley 43 forms a second section, which is located near the discharge end 104. The second section of the ultrasonic broadband liquid-solid separation strip 44 is inclined downwards, with its extension pointing towards the discharge end 104. A guide plate 7 is provided on the discharge end 104 of the housing 1, and the guide plate 7 is connected to the housing 1 and the guide bottom plate 6.
