[0002] Titanium dioxide is an important inorganic chemical pigment, mainly composed of titanium dioxide. Titanium dioxide is mainly used in industries such as coatings, inks, papermaking, plastic rubber, chemical fibers, and ceramics.

During the treatment of titanium dioxide industrial wastewater, it is usually necessary to recover the metal particles.

[0003] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: 1.

[0020] In this embodiment, as Figures 1 to 8 shown, the secondary filtration mechanism 6 includes a metal particle filter plate 601. The outer ring of the metal particle filter plate 601 is fixedly connected to the middle part of the inner wall of the filter cylinder 2. The upper part of the metal particle filter plate 601 extends to the bottom of the storage cone 5. A driving motor 602 is fixedly connected to the middle part of the inner wall of the filter cylinder 2. The rotating end of the driving motor 602 is fixedly connected to a transmission rod 603. The top of the transmission rod 603 penetrates through the metal particle filter plate 601 and is fixedly connected to the inner wall of the storage cone 5.

[0022] The outside of the adjusting ring 604 is movably sleeved with a transmission ring 608. The top of the transmission ring 608 is fixedly connected with four T-shaped connecting rods 609 equidistantly along the circumference. A compression spring 610 is fixedly connected between the top of the T-shaped connecting rod 609 and the bottom of the support ring 4. The inner ring of the transmission ring 608 is fixedly connected with four positioning pins 611 equidistantly along the circumference. The positioning pins 611 are slidably connected inside the adjacent inclined grooves 607. The outer wall of the transmission ring 608 is fixedly connected with four adjusting boxes 612 equidistantly along the circumference. The surface of the adjusting box 612 is symmetrically provided with L-shaped adjusting grooves 613. It should be noted that: when the material storage conical cylinder 5 drives the adjusting ring 604 to rotate, during the sliding process of the inclined grooves 607 and the positioning pins 611, the transmission ring 608 drives the adjusting box 612 to move upward inside the filter cylinder 2.

[0023] A bearing ring sleeve 619 is fixedly connected between the bottoms of the four T-shaped connecting rods 609. The inner ring of the bearing ring sleeve 619 is fixedly connected with the upper part of the filter recycling mechanism 7. It should be noted that: when the T-shaped connecting rod 609 moves upward along with the transmission ring 608, it will pull the upper part of the filter recycling mechanism 7 to move synchronously.

[0024] In this embodiment, as Figures 1 to 8As shown in the figure, a ring groove 614 is formed inside the support ring 4. Four grooves 615 are equidistantly arranged along the circumference on the inner wall of the ring groove 614. The four grooves 615 correspond to the four adjustment boxes 612 one by one. A secondary filter plate 616 is slidably connected inside the groove 615. One end of the secondary filter plate 616 extends into the ring groove 614. A rectangular groove 617 is formed on the inner bottom surface of the groove 615. A T-shaped adjustment rod 618 is fixedly connected to the bottom of the secondary filter plate 616. The T-shaped adjustment rod 618 is slidably connected between the corresponding rectangular groove 617 and the adjustment box 612. The lower end of the T-shaped adjustment rod 618 is slidably connected inside the corresponding L-shaped adjustment groove 613. It should be noted that: when the drive ring 608 moves upward, the L-shaped adjustment groove 613 on the side wall of the adjustment box 612 cooperates with the T-shaped adjustment rod 618 to slide, so that the T-shaped adjustment rod 618 drives the secondary filter plate 616 to move towards the center position of the ring groove 614, and the four secondary filter plates 616 move synchronously to form a disc shape for secondary filtration; and a cleaning ring is slidably connected vertically to the upper part of the inner wall of the support ring 4. A compression spring is fixedly connected between the top of the cleaning ring and the inner wall of the support ring 4. The bottom of the cleaning ring is arranged between the tops of the four secondary filter plates 616. When the four secondary filter plates 616 move away from each other, the cleaning ring can scrape and clean the tops of the secondary filter plates 616.

[0025] In this embodiment, as Figures 1 to 8 shown, the top of the adjustment ring 604 is provided with an inclined surface that cooperates with the inclined groove 607. An installation bearing is fixedly connected between the inner ring of the lower part of the adjustment ring 604 and the outer wall of the filter cylinder 2. It should be noted that: when the drive ring 608 moves downward and resets, the positioning pin 611 on the drive ring 608 cooperates with the inclined surface at the top of the adjustment ring 604 to slide, so that the positioning pin 611 stably enters the corresponding inclined groove 607 again.

[0026] In this embodiment, as Figures 1 to 8 shown, the metal particle filter plate 601 is conical. The lower part of the outer wall of the metal particle filter plate 601 is attached to the lower part of the inner wall of the storage cone 5. It should be noted that: the conical amplitude of the outer wall of the metal particle filter plate 601 is different from that of the inner wall of the storage cone 5, so that the filtered metal particles are at the conical gap position between the metal particle filter plate 601 and the storage cone 5, thereby realizing the distinction of metals with different particle sizes.

[0027] In this embodiment, as Figures 1 to 8 shown, the filtration and recovery mechanism 7 includes a grading cone sleeve 701. The grading cone sleeve 701 is rotatably connected to the lower part of the outer wall of the storage cone 5. Discharge holes 702 are formed on the lower part of the outer wall of the storage cone 5 and the surface of the grading cone sleeve 701.

[0028] Four vertical rods 703 are slidably connected to the top of the grading cone sleeve 701 at equal intervals along the circumference. A regulating ring 704 is fixedly connected between the tops of the four vertical rods 703. The outer ring of the upper part of the regulating ring 704 is fixedly connected to the inner ring of the bearing ring sleeve 619. Four regulating blocks 705 are fixedly connected to the inner ring of the regulating ring 704 at equal intervals along the circumference. Four pushing blocks 706 are fixedly connected to the outer wall of the material storage cone 5 at equal intervals along the circumference. The four pushing blocks 706 correspond to the four regulating blocks 705 one by one. Four arc-shaped adjusting bars 707 are fixedly connected to the outer wall of the material storage cone 5 at equal intervals along the circumference. The four arc-shaped adjusting bars 707 correspond to the four regulating blocks 705 one by one. It should be noted that when the regulating ring 704 drives the regulating blocks 705 to move down to the limit position, the bottom of the regulating block 705 cooperates with the surface of the corresponding arc-shaped adjusting bar 707 to slide, so that the regulating ring 704 drives the grading cone sleeve 701 to rotate through the vertical rods 703, and the discharge holes 702 on the surface of the grading cone sleeve 701 are staggered from the discharge holes 702 on the surface of the material storage cone 5. When the regulating ring 704 drives the regulating blocks 705 to move up to the limit position, during the rotation of the material storage cone 5, the pushing blocks 706 come into contact with the regulating blocks 705. At this time, the material storage cone 5 can drive the regulating ring 704 and the grading cone sleeve 701 to rotate synchronously, and at this time, the discharge holes 702 on the surface of the grading cone sleeve 701 coincide with the discharge holes 702 on the surface of the material storage cone 5.

[0029] A material guiding ring 708 that cooperates with the discharge hole 702 is fixedly connected to the outer wall of the grading cone sleeve 701. Three metal recovery boxes 709 are fixedly connected to the top of the waste water recovery tank 1. Feeding pipes 710 that cooperate with the discharge hole 702 are fixedly connected to the tops of the three metal recovery boxes 709. It should be noted that the metal particles discharged from different positions of the discharge holes 702 on the grading cone sleeve 701 will enter the cavity position between the corresponding material guiding ring 708 and the inner wall of the filter cylinder 2, and the material guiding ring 708 is inclined towards the position of the corresponding feeding pipe 710, so that the filtered metal particles are guided and conveyed from the material guiding ring 708 to the position of the feeding pipe 710, and finally enter the interior of the corresponding metal recovery box 709.

[0030] A suspended matter filter 711 is movably installed at the lower part of the inner wall of the filter cylinder 2. A drain pipe 712 is fixedly connected between the lower part of the outer wall of the filter cylinder 2 and the top of the waste water recovery tank 1. A circulating pump water pipe 713 is fixedly connected between the top of the waste water recovery tank 1 and the upper part of the waste water delivery pipe 3. It should be noted that the suspended matter filter 711 can be disassembled from the bottom of the filter cylinder 2 for easy cleaning or replacement. When the waste water delivery pipe 3 stops delivering waste water, the circulating pump water pipe 713 can pump the filtered sewage into the interior of the filter cylinder 2, and under the action of the secondary filter plate 616, the metal particles after primary filtration are flushed for the second time, reducing the situation of suspended matter adhering to the surface of the recovered metal particles. Here, both the suspended matter filter 711 and the circulating pump water pipe 713 are prior arts and will not be described in detail here.

[0031] In this embodiment, as Figures 1 to 8 shown, the diameters of the discharge holes 702 decrease successively from top to bottom. There are three types of diameters for the discharge holes 702, and the three discharge holes 702 correspond to the three material conveying pipes 710 one by one. It should be noted that the discharge hole 702 at the lowermost position is flush with the bottom of the grading cone sleeve 701 to prevent metal particles from remaining inside the grading cone sleeve 701.

[0032] Two guide rings 708 divide the space between the surface of the grading cone sleeve 701 and the inner wall of the filter cylinder 2 into three chambers, and the three chambers correspond to the three material conveying pipes 710 one by one.

[0033] In this embodiment, as Figures 1 to 8 shown, the pushing block 706 is arranged above the adjusting block 705, the arc-shaped adjusting strip 707 is arranged below the adjusting block 705, the top of the adjusting block 705 is conical, and the bottom of the adjusting block 705 is an arc surface. It should be noted that with the above settings, it is convenient for the adjusting block 705 to cooperate with the pushing block 706 when rising, and it is convenient for the adjusting block 705 to slide on the top surface of the arc-shaped adjusting strip 707 when descending.

[0034] The usage method and advantages of the present invention: The industrial acidic wastewater treatment and recovery equipment for titanium dioxide works as follows: As Figures 1 to 8 shown, when in use, first, the industrial acidic wastewater of titanium dioxide is quantitatively conveyed into the interior of the filter cylinder 2 through the wastewater conveying pipe 3. The wastewater enters the interior of the storage cone cylinder 5 through the support ring 4. The titanium metal particles are filtered by the metal particle filter plate 601 at the bottom of the storage cone cylinder 5, and the wastewater flows into the position of the suspended matter filter 711 from the metal particle filter plate 601 and then flows into the interior of the wastewater recovery tank 1 after being filtered by the suspended matter filter 711; After the wastewater conveying stops, the driving motor 602 is started to drive the transmission rod 603 and the storage cone cylinder 5 to rotate, so that the storage cone cylinder 5 makes the secondary positioning block 606 fixedly connected thereto fit with the main positioning block 605 on the inner ring of the adjusting ring 604, causing the adjusting ring 604 to start rotating with the storage cone cylinder 5. During this process, the inclined groove 607 on the surface of the adjusting ring 604 cooperates with the positioning pin 611 on the transmission ring 608 to slide, causing the transmission ring 608 to move towards the support ring 4. At this time, the adjusting box 612 on the surface of the transmission ring 608 cooperates with the T-shaped connecting rod 609 sliding inside the support ring 4 through the L-shaped adjusting groove 613, causing the four T-shaped connecting rods 609 to drive the corresponding secondary filter plates 616 to move towards the axis direction of the support ring 4. After the four secondary filter plates 616 are fitted, they are in a disc shape at the center of the support ring 4; Then, start the water pump inside the circulating pump water pipe 713 to pump the filtered wastewater in the wastewater recycling tank 1 into the interior of the wastewater delivery pipe 3. The wastewater delivery pipe 3 then conveys the filtered wastewater back into the interior of the storage cone 5. During this process, the secondary filter plate 616 performs a secondary filtration on the filtered wastewater. After the filtered wastewater enters the position of the metal particle filter plate 601, it flushes the filtered metal particles, washing the suspended matter remaining on the surface of the metal particles into the position of the suspended matter filter 711. During the rotation of the storage cone 5, the metal particles automatically stratify within the conical chamber between the storage cone 5 and the metal particle filter plate 601 according to different sizes, enabling metal particles of different sizes to come into contact with the surfaces of the storage cone 5 and the metal particle filter plate 601. During the rotation of the storage cone 5, it will bring the metal particles into contact with the surface of the metal particle filter plate 601. At this time, the friction generated can crush the suspended matter remaining on the surfaces of the metal particles and the metal particle filter plate 601, causing the suspended matter to break and be washed to the position of the suspended matter filter 711 along with the water after secondary filtration, self-cleaning the metal particle filter plate 601 while further improving the wastewater filtration effect. Meanwhile, during the upward movement, the adjusting ring 604 drives the adjusting ring 704 to move upward synchronously through the cooperation of the T-shaped connecting rod 609 and the bearing ring sleeve 619, causing the adjusting block 705 on the adjusting ring 704 to move up to the position of the pushing block 706. At this time, the rotating storage cone 5 drives the adjusting block 705 and the adjusting ring 704 to rotate synchronously through the pushing block 706. Meanwhile, during the fitting process of the adjusting block 705 on the adjusting ring 704 and the pushing block 706, the adjusting ring 704 drives the grading cone sleeve 701 to rotate synchronously through the vertical rod 703, aligning the discharge holes 702 on the grading cone sleeve 701 with the discharge holes 702 on the storage cone 5, enabling the metal particles of different sizes after being cleaned again to be discharged from the corresponding discharge hole 702 positions for automatic classification and recycling.
