Description

Technical Field

[0002] Titanium dioxide is an important inorganic chemical pigment whose main component is titanium dioxide. Titanium dioxide is mainly used in industries such as coatings, inks, papermaking, plastics and rubber, chemical fibers, and ceramics. The wastewater produced by titanium dioxide production contains metal particles and impurities. In the process of treating titanium dioxide industrial wastewater, it is usually necessary to recover the metal particles.

[0003] In the process of implementing this solution, the inventor found that the following problems in the prior art have not been well solved: 1. Since the metal particles will be recycled during the use of titanium dioxide wastewater treatment equipment, and the recovered metal requires subsequent classification treatment, it is difficult to grade and recycle the metal particles during the recycling process, and the convenience of use is poor; 2. Since there are suspended impurities in the titanium dioxide wastewater, the impurities are easy to adhere to the surface of the metal particle filter and easily enter the recycling box at the same time as the metal particles, which affects the quality of metal particle recovery. Some existing titanium dioxide wastewater treatment devices are difficult to reduce the suspended impurities adhered to the surface of the metal particle filter during use, which affects the wastewater filtration effect.

[0038] Also includes:

[0039] Support ring 4 is fixedly connected to the upper portion of the inner wall of filter cartridge 2. The bottom of wastewater delivery pipe 3 extends into support ring 4. A storage cone 5 is rotatably connected to the bottom of support ring 4. A secondary filtration mechanism 6 is movably connected between the upper portion of storage cone 5 and support ring 4. It should be noted that secondary filtration mechanism 6 is used for secondary filtration of the circulating wastewater. A sealed bearing is fixedly connected between the top of storage cone 5 and the bottom of support ring 4 to ensure stable rotation of storage cone 5 at the bottom of support ring 4.

The secondary filtering mechanism 6 drives the filtering recovery mechanism 7 to recover the filtered metal particles.

[0041] In this embodiment, Figures 1 to 8 As shown, the secondary filtration mechanism 6 includes a metal particle filter plate 601, the outer ring of which is fixedly connected to the middle portion of the inner wall of the filter cartridge 2.

It should be noted that the drive motor 602 is disposed below the metal particle filter plate 601. A protective bracket is fixedly mounted on the outer wall of the drive motor 602, and the drive motor 602 is fixedly connected to the inner wall of the filter cartridge 2 via the protective bracket.

The top of the adjustment ring 604 is provided with eight equidistantly spaced angular slots 607. It should be noted that when the storage cone 5 rotates, the secondary positioning blocks 606 cooperate with the primary positioning block 605 to cause the adjustment ring 604 to rotate synchronously.

[0043] The outer portion of the adjustment ring 604 is movably connected to a transmission ring 608. Four T-shaped connecting rods 609 are fixedly connected to the top of the transmission ring 608 at equal intervals 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. Four locating pins 611 are fixedly connected to the inner ring of the transmission ring 608 at equal intervals along the circumference. The locating pins 611 slide inside adjacent skewed slots 607. Four adjustment boxes 612 are fixedly connected to the outer wall of the transmission ring 608 at equal intervals along the circumference. The surfaces of the adjustment boxes 612 are symmetrically provided with L-shaped adjustment slots 613. It should be noted that when the storage cone 5 rotates with the adjustment ring 604, and during the sliding movement of the skewed slots 607 and the locating pins 611, the transmission ring 608 moves upward with the adjustment boxes 612 inside the filter barrel 2.

[0044] A bearing ring 619 is fixedly connected between the bottoms of the four T-shaped connecting rods 609, and the inner ring of the bearing ring 619 is fixedly connected to the upper part of the filter recovery mechanism 7. It should be noted that when the T-shaped connecting rod 609 moves upward with the transmission ring 608, it will pull the upper part of the filter recovery mechanism 7 to move synchronously.

[0045] In this embodiment, Figures 1 to 8 As shown, an annular groove 614 is provided inside the support ring 4, and four grooves 615 are provided on the inner wall of the annular groove 614 at equal intervals along the circumference. The four grooves 615 correspond one-to-one to the four adjustment boxes 612. A secondary filter plate 616 is slidably connected inside the groove 615. One end of the secondary filter plate 616 extends to the inside of the annular groove 614. A rectangular groove 617 is provided 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.

It should be noted that: when the transmission ring 608 moves upward, the L-shaped adjustment groove 613 on the side wall of the adjustment box 612 slides in conjunction with the T-shaped adjustment rod 618, so that the T-shaped adjustment rod 618 moves the secondary filter plate 616 to 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 the upper part of the inner wall of the support ring 4 is vertically slidably connected to a cleaning ring, and an extrusion spring is fixedly connected between the top of the cleaning ring and the inner wall of the support ring 4, and 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 back to back, the cleaning ring can scrape and clean the top of the secondary filter plate 616.

[0046] In this embodiment, Figures 1 to 8 As shown, the top of the adjustment ring 604 is configured as an inclined surface that cooperates with the chute 607, and a mounting bearing is fixedly connected between the inner ring of the lower portion of the adjustment ring 604 and the outer wall of the storage cone 5. It should be noted that when the transmission ring 608 moves downward and resets, the positioning pin 611 on the transmission ring 608 cooperates and slides with the inclined surface at the top of the adjustment ring 604, allowing the positioning pin 611 to re-enter the corresponding chute 607 stably.

[0047] In this embodiment, Figures 1 to 8 As shown, the metal particle filter plate 601 is configured in a conical shape, with the lower portion of the outer wall of the metal particle filter plate 601 abutting against the lower portion of the inner wall of the storage cone 5. It should be noted that the taper of the outer wall of the metal particle filter plate 601 is different from the taper of the inner wall of the storage cone 5, so that the filtered metal particles are located in the conical gap between the metal particle filter plate 601 and the storage cone 5, thereby achieving separation of metals of different particle sizes.

[0048] In this embodiment, Figures 1 to 8 As shown, the filtering and recovering mechanism 7 includes a grading cone sleeve 701 , which is rotatably connected to the lower portion of the outer wall of the storage cone 5 , and discharge holes 702 are provided on the lower portion of the outer wall of the storage cone 5 and the surface of the grading cone sleeve 701 .

[0049] The top of the grading cone sleeve 701 is slidably connected with four vertical rods 703 at equal intervals along the circumference, and an adjusting ring 704 is fixedly connected between the tops of the four vertical rods 703. The outer ring of the upper part of the adjusting ring 704 is fixedly connected to the inner ring of the bearing ring sleeve 619, and the inner ring of the adjusting ring 704 is fixedly connected with four adjusting blocks 705 at equal intervals along the circumference. The outer wall of the storage cone 5 is fixedly connected with four pushing blocks 706 at equal intervals along the circumference, and the four pushing blocks 706 correspond one-to-one to the four adjusting blocks 705. The outer wall of the storage cone 5 is fixedly connected with four arc-shaped adjusting strips 707 at equal intervals along the circumference, and the four arc-shaped adjusting strips 707 correspond one-to-one to the four adjusting blocks 705. It should be noted that: when the adjusting ring 704 moves down to the limit position with the adjusting block 705, the bottom of the adjusting block 705 slides in cooperation with the surface of the corresponding arc-shaped adjusting bar 707, so that the adjusting ring 704 rotates with the grading cone sleeve 701 through the vertical rod 703, and the discharge hole 702 on the surface of the grading cone sleeve 701 is staggered with the discharge hole 702 on the surface of the storage cone 5; when the adjusting ring 704 moves up to the limit position with the adjusting block 705, the storage cone 5 contacts the pushing block 706 with the adjusting block 705 during the rotation process. At this time, the storage cone 5 can rotate synchronously with the adjusting ring 704 and the grading cone sleeve 701, and at this time the discharge hole 702 on the surface of the grading cone sleeve 701 coincides with the discharge hole 702 on the surface of the storage cone 5.

[0050] A guide ring 708 that matches 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 wastewater recovery tank 1. The tops of the three metal recovery boxes 709 are all fixedly connected to a delivery pipe 710 that matches the discharge hole 702. It should be noted that when the metal particles discharged from the discharge holes 702 at different positions on the grading cone sleeve 701 enter the cavity between the corresponding guide ring 708 and the inner wall of the filter cartridge 2, and the guide ring 708 is tilted toward the corresponding delivery pipe 710, the filtered metal particles are guided and transported by the guide ring 708 to the delivery pipe 710, and finally enter the interior of the corresponding metal recovery box 709.

[0051] A suspended solids filter 711 is movably mounted on the lower portion of the inner wall of the filter cartridge 2. A drain pipe 712 is fixedly connected between the lower portion of the outer wall of the filter cartridge 2 and the top of the wastewater recovery tank 1. A circulating pump water pipe 713 is fixedly connected between the top of the wastewater recovery tank 1 and the upper portion of the wastewater delivery pipe 3. It should be noted that the suspended solids filter 711 can be removed from the bottom of the filter cartridge 2 for easy cleaning or replacement. When the wastewater delivery pipe 3 stops delivering wastewater, the circulating pump water pipe 713 can pump the filtered sewage into the interior of the filter cartridge 2 and, under the action of the secondary filter plate 616, perform a secondary flushing of the metal particles after the initial filtration, thereby reducing the amount of suspended solids adhering to the surface of the recovered metal particles. The suspended solids filter 711 and the circulating pump water pipe 713 are both prior art and will not be described in detail here.

[0052] In this embodiment, Figures 1 to 8 As shown, the diameters of the discharge holes 702 decrease from top to bottom, and there are three different diameters of the discharge holes 702, each corresponding to one of the three feed pipes 710. It should be noted that the lowest discharge hole 702 is flush with the bottom of the grading cone sleeve 701 to prevent metal particles from remaining inside the grading cone sleeve 701.

[0053] The two guide rings 708 divide the area between the surface of the grading cone sleeve 701 and the inner wall of the filter cartridge 2 into three chambers, and the three chambers correspond to the three conveying pipes 710 one by one.

[0054] In this embodiment, Figures 1 to 8 As shown, push block 706 is disposed above adjustment block 705, and arc-shaped adjustment bar 707 is disposed below adjustment block 705. The top of adjustment block 705 is conical, and the bottom of adjustment block 705 is arc-shaped. It should be noted that this arrangement facilitates the coordinated operation of adjustment block 705 with push block 706 when the adjustment block 705 is raised, and facilitates the sliding of adjustment block 705 on the top surface of arc-shaped adjustment bar 707 when the adjustment block 705 is lowered.

[0055] The use method and advantages of the present invention: The industrial acid wastewater treatment and recovery equipment of titanium dioxide has the following working process:

[0056] like Figures 1 to 8 As shown, when in use, the industrial acidic wastewater containing titanium dioxide is first quantitatively transported to the interior of the filter cylinder 2 through the wastewater delivery pipe 3, and the wastewater enters the interior of the storage cone 5 through the support ring 4. The titanium metal particles are filtered out by the metal particle filter plate 601 at the bottom of the storage cone 5, and the wastewater flows from the metal particle filter plate 601 to the suspended solids filter 711. After being filtered by the suspended solids filter 711, it flows into the interior of the wastewater recovery tank 1;

[0057] After the wastewater transportation stops, the driving motor 602 is started to rotate the transmission rod 603 and the storage cone 5, so that the storage cone 5 and the fixedly connected slave positioning block 606 are fitted with the main positioning block 605 of the inner ring of the adjusting ring 604, so that the adjusting ring 604 starts to rotate with the storage cone 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, so that the transmission ring 608 moves toward the support ring 4. At this time, the adjustment 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 adjustment groove 613, so that the four T-shaped connecting rods 609 carry the corresponding secondary filter plates 616 to move toward the axial direction of the support ring 4. After fitting, the four secondary filter plates 616 are disc-shaped and are located in the center position of the support ring 4;

[0058] Then, the water pump inside the circulation pump water pipe 713 is started to pump the filtered wastewater inside the wastewater recovery tank 1 into the wastewater delivery pipe 3, and the wastewater delivery pipe 3 delivers the filtered wastewater to the inside of the storage cone 5 again. During this process, the secondary filter plate 616 performs a secondary filtration on the filtered wastewater, and after the filtered wastewater enters the metal particle filter plate 601, it flushes the filtered metal particles and flushes the suspended matter remaining on the surface of the metal particles into the suspended matter filter 711.

[0059] During the rotation of the storage cone 5, the metal particles are automatically stratified according to their sizes inside the conical chamber between the storage cone 5 and the metal particle filter plate 601, so that metal particles of different sizes can all 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, the metal particles will come into contact with the surface of the metal particle filter plate 601. The friction generated at this time can crush the surface of the metal particles and the suspended matter remaining on the surface of the metal particle filter plate 601, so that the suspended matter is broken and flushed to the position of the suspended matter filter 711 along with the water after the secondary filtration, thereby self-cleaning the metal particle filter plate 601 and further improving the wastewater filtration effect.

[0060] At the same time, during the rising process, the adjusting ring 604 moves up synchronously with the adjusting ring 704 through the T-shaped connecting rod 609 and the bearing ring sleeve 619, so that the adjusting block 705 on the adjusting ring 704 moves up to the position of the pushing block 706. At this time, the rotating storage cone 5 rotates synchronously with the adjusting block 705 and the adjusting ring 704 through the pushing block 706. At the same time, in the process of the adjusting block 705 and the pushing block 706 on the adjusting ring 704 being fitted together, the adjusting ring 704 rotates synchronously with the grading cone sleeve 701 through the vertical rod 703, so that the discharge hole 702 on the grading cone sleeve 701 coincides with the discharge hole 702 on the storage cone 5, so that the metal particles of different sizes after cleaning are discharged from the corresponding discharge hole 702 position, and are automatically graded and recovered.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
