Technical Field

[0001] The invention relates to the technical field of impurity removal and purification of non-metallic mineral materials, and in particular to an ultrasonic micro-acid scrubbing method and device. Background Art

[0002] The cleaning of non-metallic mineral materials is mainly to remove impurities on the surface of the minerals and improve their purity and quality. There are many types of cleaning equipment for non-metallic mineral materials, including scrubbers, rod mills, magnetic separators, flotation machines, acid leaching equipment, gravity separation equipment, ultrasonic cleaning equipment and microbial culture equipment.

[0003] Among them, ultrasonic micro-acid scrubbing uses the cavitation effect, acceleration effect and straight-through flow effect generated by ultrasound in liquid to clean minerals. During cleaning, the minerals are placed in ultrasonic cleaning equipment and the surface impurities are removed by the action of ultrasound. It is mainly used to remove impurities such as secondary iron film on the surface of particles that are difficult to remove.

DETAILED DESCRIPTION

[0033] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0034] In the description of the present invention, it should be understood that “plurality” means two or more than two, unless otherwise clearly defined.

[0035] See also Figure 6 The present invention provides an ultrasonic micro-acid scrubbing method, comprising the following steps:

[0036] S1: Inject pure water, hydrofluoric acid and hydrochloric acid into the acid preparation tank to form a mixed acid hot liquid of specified concentration;

[0037] Specifically, in this embodiment, eight tons of quartz sand with a particle size range of 60 to 160 meshes is used as the experimental material. First, 10.8 cubic meters of hot pure water at about 50 degrees Celsius, 360 liters of 40% hydrofluoric acid, and 840 liters of 30% hydrochloric acid are injected into an acid preparation tank with a capacity of 15 cubic meters to form 12 cubic meters of a mixed acid hot liquid of 0.12% hydrofluoric acid and 0.21% hydrochloric acid.

[0038] S2: injecting the generated mixed acid hot liquid into the mixing barrel, and at the same time conveying the quartz sand to be pickled into the mixing barrel;

[0039] S3: The added quartz sand and the mixed acid hot liquid are mixed into ore slurry through the internal stirring mechanism of the stirring barrel;

[0040] Specifically, the mixed acid hot liquid is continuously injected into the 10 cubic meter mixing barrel at a flow rate of 12 cubic meters per hour, and the quartz sand to be acid-washed is continuously transported into the mixing barrel at a flow rate of 8 tons per hour. Under the action of the stirring paddle 52, a slurry with a concentration of about 40% is formed.

[0041] S4: continuously injecting the generated slurry into the ultrasonic micro-acid scrubbing device for ultrasonic cleaning;

[0042] S5: The pickled pulp is deacidified by a vacuum belt deacidifier, and then fed into the mixing tank again by a vibrating feeder;

[0043] S6: The secondary input slurry is mixed with the added warm secondary reverse osmosis purified water in the mixing barrel, and then ultrasonically cleaned by the ultrasonic micro-acid scrubbing device. After cleaning, it is deacidified again by the vacuum belt deacidifier and transported to the mixing barrel by the vibrating feeder. The cleaning cycle is repeated four to five times;

[0044] S7: After repeated cleaning, when the pH value of the wastewater reaches neutral, the warm secondary reverse osmosis pure water used for cleaning is switched to normal temperature EDI ultrapure water. After switching to normal temperature EDI ultrapure water, it is necessary to clean twice more;

[0045] S8: The cleaned ore pulp can be dehydrated by a vacuum belt dehydrator, dried by a box-type double quartz tube, and subjected to strong magnetic separation by an electromagnetic magnetic separator to form the final high-purity quartz sand product.

[0046] Specifically, the slurry is continuously injected into the ultrasonic hot liquid immersion washing machine unit from the discharge port of the mixing barrel, and then according to the liquid level of the slurry flowing into each "ultrasonic hot liquid immersion washing machine" equipment, the stirring paddle motor and ultrasonic generator of the equipment are started after the liquid level exceeds the upper edge of the ultrasonic vibration plate;

[0047] In order to solve the problem that some materials cannot be fully stirred and ultrasonically pickled during startup and shutdown, considering that the slurry stays in each device for about five minutes, after the test material is discharged from the last device, all the slurry discharged in the first half hour is returned to the mixing barrel for secondary processing using an acid-resistant mortar pump.

[0048] After all the slurry in the mixing barrel has flowed out, according to the liquid level of the slurry flowing out of each "ultrasonic hot liquid immersion machine" equipment, turn off the ultrasonic generator of the equipment when the liquid level is lower than the upper edge of the ultrasonic vibration plate, and turn off the stirring paddle motor after the slurry has basically flowed out;

[0049] The pickled slurry is deacidified by a vacuum belt deacidifier and then fed into a mixing barrel at a flow rate of eight tons of dry sand per hour using a vibrating feeder. At the same time, warm secondary reverse osmosis pure water at a temperature of fifty to sixty degrees Celsius is injected into the mixing barrel at a flow rate of twelve cubic meters per hour. The quartz sand is continuously ultrasonically cleaned in the ultrasonic pickling equipment according to the same process as ultrasonic pickling. The slurry flowing out of the last equipment is then passed through a vacuum belt deacidifier to remove the acid. This cycle of cleaning is repeated four to five times. After the wastewater reaches a neutral pH value, the warm secondary reverse osmosis pure water at fifty to sixty degrees Celsius used for cleaning is switched to room temperature EDI ultrapure water, and then washed twice more. The high-purity quartz sand product of the experimental group is obtained by dehydration using a vacuum belt dehydrator, drying using a box-type double quartz tube, and strong magnetic separation using an electromagnetic magnetic separator.

[0050] Among them, two tons of the same quartz sand sample were selected and put into the currently commonly used two-cubic-meter reactor. According to the current standard process, two tons of quartz sand, six hundred liters of pure water, two hundred liters of 40% hydrofluoric acid, and four hundred liters of 30% hydrochloric acid were added. The hot water bath temperature was set to ninety-five degrees Celsius. After heating and rotating for twenty hours, the reaction was carried out, followed by acid removal, cleaning, dehydration, drying, and strong magnetic separation to obtain a high-purity quartz sand product for the comparison group.

[0051] By comparing the two methods, it can be concluded that under the same production conditions, the amount of acid used in continuous ultrasonic micro-acid scrubbing is less than 40% of the acid used in the reactor, and the pickling time is only 40 minutes. At the same time, the product quality is better. A set of continuous ultrasonic pickling equipment can process eight tons of products per hour, realizing continuous production with automated control, with an annual processing capacity of more than 50,000 tons, which is more environmentally friendly and safe, and the product quality is more stable and consistent.

[0052] See also Figures 1 to 5 Preferably, the ultrasonic micro-acid scrubbing device used in the above ultrasonic micro-acid scrubbing method includes a chassis body 1, a supporting chassis 2, a matching top cover 3, an inner partition 4, a working component 5 and an auxiliary component 6;

Each chassis body 1 is provided with an inner partition 4 to form a double-slot structure. The inner partition 4 begins to have square holes to ensure that the slurry inside the chassis body 1 can flow normally. The chassis body 1 is an octagonal columnar structure with a volume of one cubic meter. At the same time, the chassis body 1 is also provided with corresponding feed channels and discharge channels. In order to facilitate the flow of the slurry inside the chassis body 1, the bottom wall inside the chassis body 1 is inclined. The chassis body 1 discharge channel located above in the chassis body 1 unit is connected to the chassis body 1 feed channel adjacent to the bottom to ensure that the slurry can continue to flow in the chassis body 1 unit;

[0055] The chassis body 1 unit is spliced ​​by overlapping, and the support base 2 at the bottom of the upper chassis body 1 is replaced with the matching top of the adjacent chassis body 1 below to complete the matching of the two adjacent chassis bodies 1. The overlapping method can effectively reduce the site occupation area. In actual use, the height of the chassis body 1 can be reduced by expanding the surface area of ​​the chassis body 1 according to actual needs, thereby avoiding the problem of the entire chassis body 1 unit being too high after overlapping.

[0056] The supporting side frame 61 is provided on the side of the chassis body 1 unit, and the supporting side frame 61 is provided with a corresponding expenditure boss. The expenditure boss of the supporting side frame 61 is provided with a card slot, and the card-in platform 62 provided at the bottom of the chassis body 1 matches the card slot on the expenditure boss of the supporting side frame 61. The expenditure boss provided on the supporting side frame 61 can support the chassis body 1 separated by two boxes on the chassis body 1 unit to ensure the stability of the operation of the entire chassis body 1 unit after overlapping.

[0057] Preferably, the working assembly 5 includes an ultrasonic vibrator device 51 , a stirring paddle 52 and a stirring member 53 , and the stirring member 53 includes a connecting bevel gear 531 , a driving shaft 532 , a driving bevel gear 533 and a driving motor 534 .

[0060] When this embodiment is in use, two pairs of four groups of fifteen ultrasonic vibrators 51 with an oscillation frequency of 28 kHz and a single power of 100 watts are installed on the middle and lower part of the side of each chassis body 1. The total ultrasonic power of each double-slot scrubbing machine device is: 2*4*15*0.1=12 kilowatts;

[0061] At the same time, since the chassis body 1 forms a double-groove structure through the inner partition 4, each chassis body 1 is provided with two stirring paddles 52, and the paddle ends of the two stirring paddles 52 are fixed with the connecting bevel gears 531, and the two connecting bevel gears 531 are correspondingly engaged with the two driving bevel gears 533 provided on the driving shaft 532. The driving shaft 532 is driven by the driving motor 534. When the driving shaft 532 rotates, the two driving bevel gears 533 on the driving shaft 532 can simultaneously drive the connecting bevel gears 531 provided on the two stirring paddles 52, thereby completing the synchronous driving of the two stirring paddles 52. It should be noted that in this scheme, since the bottom wall inside the chassis body is inclined, the two stirring paddles 52 are also inclined, so that the slurry flowing inside the chassis body can be mixed and stirred more efficiently.

[0062] Preferably, the auxiliary component 6 includes a supporting side frame 61, a card-in platform 62, a mounting frame 63 and a placing and removing component 64, and the placing and removing component 64 includes a sleeve bracket 641, a lifting platform 642, a lifting mechanism 643, a plug-in bracket 644 and a connecting component 645, and the connecting component 645 includes a driving bracket 6451, a driving screw 6452, a linkage gear 6453, a gear chain 6454 and a driving motor 6455.

[0065] Furthermore, the connecting component 645 includes a driving bracket 6451, a driving screw 6452, a linkage gear 6453, a tooth chain 6454 and a driving motor 6455. The two driving brackets 6451 are fixedly connected to the plug-in bracket 644 and are slidably installed on the lifting platform 642; the two driving screws 6452 are respectively threadedly connected to the two driving brackets 6451, and the two driving screws 6452 are rotatably installed on the lifting platform 642; the two linkage gears 6453 are respectively fixedly installed on the two driving screws 6452; the two sides of the tooth chain 6454 are respectively sleeved on the two linkage gears 6453; the output shaft of the driving motor 6455 is connected to one of the driving screws 6452, and the driving motor 6455 is installed on the lifting platform 642.

[0066] When the present embodiment is in use, the sleeve brackets 641 are fixedly installed on both sides of each chassis body. By cooperating with the plug-in bosses at the ends of the sleeve brackets 641 and the plug-in bosses 644, the corresponding chassis body can be clamped. The plug-in bosses of the plug-in brackets 644 are provided with card slots to ensure that when the chassis body 1 is driven to move, the sleeve brackets 641 on both sides of the chassis body 1 can be stably matched with the plug-in brackets 644.

The two linkage gears 6453 are connected by the tooth chain 6454. One of the driving screws 6452 is fixed to the output shaft of the driving motor 6455, so that when the driving motor 6455 drives the corresponding driving screw 6452 to rotate, the linkage gear 6453 can drive the other driving screw 6452 and the linkage gear 6453 to rotate through the tooth chain 6454, so as to synchronously drive the two driving screws 6452, thereby completing the corresponding drive of the driving bracket 6451;

[0068] During actual operation, the user can first raise the lifting platform 642 to the corresponding height through the lifting mechanism 643 according to actual conditions, and then drive the two driving screws 6452 through the driving motor 6455 in coordination with the linkage gear 6453 and the tooth chain 6454, and then drive the driving bracket 6451 to move through the two driving screws 6452, so that the plug-in bracket 644 can be driven by the driving bracket 6451 to cooperate with the sleeve bracket 641 on both sides of the chassis body 1 at the specified position. After the plug-in bracket 644 is plugged in with the corresponding sleeve bracket 641, the lifting platform 642 can lift the corresponding chassis body 1, and then retract and descend. In order to complete the automatic disassembly of the chassis body 1, it is more convenient for users to maintain and replace the chassis body 1 and corresponding components at a high place, and it is also convenient for the installation of the chassis body 1 unit. It should be noted that this structure can only disassemble the chassis body 1 from the highest point. Before disassembly, it is also necessary to cut off the connection between the corresponding chassis body 1 and the chassis body 1 below. As for how to cut off the connection between the two chassis bodies 1, it can be manually dismantled by using the hand climbing frame set on the supporting side frame 61. As for the disassembly of the entire chassis body 1 due to its own weight and height, manual operation is difficult and risky, so it can be automatically disassembled through the above structure.

A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.

5. An ultrasonic micro-acid scrubbing method, applied to the ultrasonic micro-acid scrubbing device according to claim 1, characterized in that: The following steps are involved: Inject pure water, hydrofluoric acid and hydrochloric acid into the acid preparation tank to form a mixed acid hot liquid of specified concentration; The generated mixed acid hot liquid is injected into the mixing barrel, and the quartz sand to be pickled is transported into the mixing barrel at the same time; The added quartz sand and the mixed acid hot liquid are mixed into ore slurry through the stirring mechanism inside the mixing barrel; The generated slurry is continuously injected into the ultrasonic micro-acid scrubbing device for ultrasonic cleaning; The pulp after pickling is deacidified by a vacuum belt deacidifier, and then the pulp is fed into the mixing tank again by a vibrating feeder; The secondary input slurry is mixed with the warm secondary reverse osmosis purified water in the mixing barrel, and then ultrasonically cleaned by the ultrasonic micro-acid scrubbing device. After cleaning, it is deacidified again by the vacuum belt deacidifier and transported to the mixing barrel by the vibrating feeder. The cleaning cycle is repeated four to five times. After repeated cleaning, when the wastewater reaches a neutral pH value, the warm secondary reverse osmosis pure water used for cleaning is switched to normal temperature EDI ultrapure water. After switching to normal temperature EDI ultrapure water, it is necessary to clean twice more. The cleaned slurry can be dehydrated by a vacuum belt dehydrator, dried by a box-type double quartz tube, and subjected to strong magnetic separation by an electromagnetic separator to form the final high-purity quartz sand product.
