The speed of rotation of the turntable 30, the number of leaching tanks 32, the position of the discharge stations and the discharge pattern can be adjusted by the person skilled in the art according to the actual requirements.
The operation of the barium sulfide black ash leaching device 1 according to an embodiment of the present invention is described below with reference to fig. 1.
Taking barium sulfide black ash as an example, the calcining kiln tail cover 40 is installed at the tail of the rotary kiln, and the barium sulfide black ash generated by calcining is collected and settled into the cooling ash collecting device 10 by gravity for cooling. The discharge valve 20 is opened and the black ash is settled by gravity into the leaching ash collecting barrel 50 previously placed on the rotating disc 30. The upper brine inlet begins to discharge water, and after the water level of the leaching tank 32 reaches a certain height, the turntable 30 rotates by a preset angle, so that the upper leaching ash-collecting barrel 50 and the lower leaching ash-collecting barrel 50 in the rotating direction are aligned with the discharge valve 20.
During the rotation of the rotating disc 30, the barium sulfide black ash is naturally leached as the rotating disc 30 rotates nearly one circle. The leaching ash collection barrel 50 leaches the black ash to take away small barium sulfide particles in the barrel, and large barium residues are blocked in the barrel.
After the rotary table 30 rotates for nearly one circle, the leached leaching ash collecting barrel 50 is moved out at the unloading station, the leached leaching ash collecting barrel is placed back to the leaching groove 32 after slag discharging, and the rotary table 30 continues to rotate to move the leached leaching ash collecting barrel 50 which is emptied after unloading to the position below the unloading valve 20 to wait for material receiving.
According to the barium sulfide black ash leaching device 1 provided by the embodiment of the invention, the turntable 30 is arranged, the plurality of leaching grooves 32 are arranged on the turntable 30, and the leaching ash collecting barrel 50 is arranged in each leaching groove 32, so that the material receiving and leaching processes can be automatically completed along with the rotation circulation of the turntable 30.
In addition, by arranging the cooling ash collecting device 10, the black ash can be directly cooled after the black ash is collected by the tail cover 40 of the calcining kiln, the time for waiting for the cooling of the black ash is shortened, and the black ash leaching efficiency is improved.
Therefore, the barium sulfide black ash leaching device 1 has the advantages of high automation degree, compact structure and the like.
A barium sulfide black ash leaching apparatus 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
In some embodiments of the invention, as shown in FIG. 1, a barium sulfide black ash leaching device 1 according to embodiments of the invention includes a calcining kiln tail hood 40, a cooling ash collector 10, a rotating disk 30, a dilute brine inlet 90, and a plurality of leaching ash collection barrels 50.
Specifically, as shown in fig. 1, the barium sulfide black ash leaching device 1 further comprises a transfer mechanical arm 60, wherein the transfer mechanical arm 60 is used for removing the leaching ash collecting barrel 50 from the leaching tank 32. Therefore, the transferring mechanical arm 60 can be used for transferring the leaching ash collecting barrel 50, the automation degree is further improved, and the manual labor amount is reduced.
Specifically, the transfer robot 60 may be positioned above the leach tank 32 adjacent to the leach tank 32 below the discharge valve 20. Thus, the rotary table 30 rotates in the direction from the transferring mechanical arm 60 to the discharging valve 20, the material is loaded at the discharging valve 20 and is discharged at the transferring mechanical arm 60, and the natural leaching is performed for nearly one circle during the rotation of the rotary table 30.
Advantageously, as shown in fig. 1, the barium sulfide black ash leaching plant 1 further comprises a slag washing vat 70, and the transfer robot 60 is used to move the leaching ash collection vat 50 from the leaching tank 32 to the slag washing vat 70. Thus, the leaching ash collecting barrel 50 can be cleaned again by using the slag washing barrel 70 to remove a small amount of barium sulfide solution attached to the undissolved barium slag and the inner wall surface of the barrel.
Specifically, the slag washing bucket 70 may be plural. The transferring mechanical arm 60 can sequentially put the leaching ash collecting barrel 50 into a plurality of slag washing barrels 70 for cleaning for a plurality of times so as to improve the cleaning effect.
More specifically, as shown in fig. 1, the barium sulfide black ash leaching device 1 further comprises a slag discharge collecting barrel 80, and the transfer mechanical arm 60 is used for moving the leaching ash collecting barrel 50 from the slag washing barrel 70 to the slag discharge collecting barrel 80. This allows the washed leach ash collection bucket 50 to be moved to the slag discharge collection bucket 80 for slag discharge.
Advantageously, the bottom wall of the leaching dust-collecting vat 50 is provided with a plurality of flaps that are reversible between an open position, in which the bottom wall of the leaching dust-collecting vat 50 is open for the discharge of the black ash leached slag, and a closed position, in which the bottom wall of the leaching dust-collecting vat 50 is closed, said flaps being configured to rotate into said open position when the leaching dust-collecting vat 50 is placed in the unloading collecting vat 80. Therefore, the slag can be automatically discharged when the transferring mechanical arm 60 puts the leaching ash collecting barrel 50 into the slag discharging collecting barrel 80, the manual slag discharging process is omitted, and the automation degree of the barium sulfide black ash leaching device 1 is further improved.
Further, a slag discharge plate is provided in the slag discharge collection bucket 80, the slag discharge plate being configured to abut against the flap when the leaching ash collection bucket 50 is placed in the slag discharge collection bucket 80 to rotate the flap to the open position. Therefore, the control on the position of the turning plate can be realized, and the automatic slag unloading is realized.
More specifically, as shown in FIG. 1, the peripheral wall and the bottom wall of the leaching dust collecting barrel 50 are provided with filtering holes. Specifically, the turning plate is provided with the filtering hole which is configured to allow water and small barium sulfide particles to pass through and block large barium residues. Thus, water flows into the barrel from the filtering holes, small-particle barium sulfide in the barrel is dissolved and taken away, and large-particle barium slag is blocked in the barrel. This allows leaching of black ash.
FIG. 1 shows a barium sulfide black ash leaching apparatus 1 according to one specific example of the invention. As shown in figure 1, a plurality of concentrated brine outlet ports 33 are arranged on the rotating disc 30, the concentrated brine outlet ports 33 are arranged at intervals along the circumferential direction of the rotating disc 30, and each leaching tank 32 is communicated with at least two concentrated brine outlet ports 33. Specifically, the concentrated brine outlet 33 includes an upper concentrated brine outlet for discharging a relatively clear solution and a lower concentrated brine outlet for discharging a relatively turbid solution. This may facilitate the discharge of the barium sulfide solution.
Advantageously, the leaching ash collection bucket 50 is adapted to be placed at the center of gravity of the leaching tank 32. This facilitates smooth rotation of the turntable 30 and improves leaching.
Specifically, as shown in fig. 1, the partition plate 31 is oriented in the radial direction of the rotating disk 30, and a plurality of partition plates 31 are arranged at equal intervals in the circumferential direction of the rotating disk 30. This facilitates the formation of the leach tank 32 and facilitates control of the rotational speed of the rotor plate 30.
The cooling ash collecting device 10 is cooled by circulating cooling water, and a cooling water inlet and a cooling water outlet are arranged on the cooling ash collecting device 10. Therefore, the cooling of the black ash can be accelerated, the cooling efficiency is improved, the waiting time for cooling is further reduced, and the leaching efficiency is improved.
The cooling ash collecting device 10 is fixedly connected below the calcining kiln tail cover 40 through a flange.
The operation of a barium sulfide black ash leaching unit 1 according to an embodiment of the invention is described below with reference to fig. 1.
The discharge valve 20 is located above one of the leaching tanks 32, here considered as the loading station, and the discharge station is located at the other leaching tank 32 adjacent to this leaching tank 32 for discharging, the leaching tank 32 between the loading station and the discharge station being considered as a plurality of leaching sites in the direction of rotation. Taking 8 leaching tanks 32 as an example, there are 6 leaching stations between the loading station and the unloading station.
The calcining kiln tail cover 40 is arranged at the tail of the rotary kiln, and is used for collecting the barium sulfide black ash generated by calcining, and the collected barium sulfide black ash is settled into the cooling ash collecting device 10 through gravity for cooling by circulating water. The discharge valve 20 is opened, and the black ash is settled into the leaching ash collecting barrel 50 which is arranged at the gravity center of the material loading position on the rotary disc 30 in advance through gravity. After the dilute brine inlet above the feed level begins to drain to a certain height, the turntable 30 rotates 45 degrees anticlockwise, and the barium sulfide black ash begins to be naturally leached in water for six leaching station times. The side and the bottom of the leaching ash collecting barrel 50 are provided with holes, water can flow into the barrel through the holes on the side and the bottom to dissolve and take away small barium sulfide particles in the barrel, and large barium residues are blocked in the barrel.
After the barium sulfide black ash is naturally leached at six leaching stations, at a discharging station, a transferring mechanical arm 60 lifts a leaching ash collecting barrel 50 to two slag washing barrels 70 in sequence for washing twice so as to remove a small amount of barium sulfide solution attached to the undissolved barium slag and the inner wall surface of the barrel. Meanwhile, valves of the upper concentrated brine outlet and the concentrated brine outlet 33 are sequentially opened, the upper concentrated brine outlet at the higher point discharges relatively clear barium sulfide solution, and the concentrated brine outlet 33 at the lower point discharges relatively turbid barium sulfide solution which is respectively discharged into the two clarification tanks. After the slag is washed, when the transferring mechanical arm 60 extracts and leaches the ash collecting barrel 50 and puts the ash collecting barrel into the slag discharging collecting barrel 80, a slag discharging plate arranged in the barrel can jack up a turning plate at the bottom of the ash collecting barrel 50 to rotate, so that automatic slag discharging can be realized; finally, the ash-collecting barrel 50 is put back into the original leaching tank 32 and rotates along with the rotary disc 30 to carry out the next cycle of leaching process.
The cooling and dust collecting device 10 cools the barium sulfide black dust in a circulating water cooling mode, so that the preparation time of the barium sulfide solution is shortened. The rotary table 30 is provided with eight independent leaching tanks 32, and the leaching rate of barium sulfide is greatly improved, barium ions adhered to barium slag are reduced, and the concentration of barium sulfide in a leaching solution is effectively improved by adopting an intermittent feeding and continuous leaching mode.
