Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically a treatment device that uses pyrite in conjunction with a magnetic field to remove chromium from wastewater. Background Technology

[0002] Chromium is an indispensable and important metallic element in my country's industrialization process. It is widely used in electroplating, leather making, and steel and chemical industries, generating a large amount of chromium-containing wastewater during the production process. Chromium exists in various valence states in nature, while trivalent and hexavalent chromium are relatively stable. Other oxidation states are often unstable intermediate products. Cr(VI) is highly mobile and often exists in aqueous solution as an oxygen-containing anion. Moreover, its toxicity is much higher than that of Cr(III). Research on converting Cr(VI) to Cr(III) in groundwater environments is a difficult problem in the remediation of Cr(VI) pollution.

[0003] Porous iron, as a highly efficient remediation material, has shown potential in removing Cr(VI) from polluted water when treating chromium in wastewater. The synergistic effect of pyrite and a weak magnetic field provides an effective way to further enhance its remediation capabilities. During treatment, porous iron and pyrite are used as filter materials to filter wastewater. However, when replacing the filter materials, the entire device needs to be disassembled and the filter materials removed for replacement, which is relatively complicated and inefficient. In order to facilitate the replacement of filter materials in the treatment device, a treatment device that uses pyrite in conjunction with a magnetic field to remove chromium from wastewater is provided.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1.

The fixed block is displaced into the fixed groove by the elastic force of the first spring, fixing the connecting plate, which facilitates the replacement of filter material. Moreover, when one storage seat is in use, material can be added to another storage seat, improving the efficiency of filter material replacement.

[0018] 2. By setting up a fixing mechanism, the magnet is placed between two clamping plates. Then, the gear ring is rotated, which drives the second spur gear to rotate. The rotation of the second spur gear causes the two clamping plates to move closer together. The displacement of the clamping plates clamps and fixes the magnet. Then, the locking block is rotated, and the locking block rotates into the locking groove to fix the gear ring. When installing the clamping plates, the horizontal plate moves into the horizontal groove and contacts the pressing block, pushing the pressing block to move. The positioning frame moves and engages with the positioning block, reinforcing the position of the clamping plates. This facilitates the installation and removal of the magnet and prevents the magnet from loosening during use. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0030] Please see Figures 1 to 8 In this embodiment of the invention, a treatment device for removing chromium from wastewater using pyrite and a magnetic field includes a treatment box 1. A feed pipe 2 is fixedly connected to the top of the treatment box 1, and a discharge pipe 3 is fixedly connected to the bottom of the treatment box 1. Magnets 4 are arranged on both sides of the treatment box 1. The filter material inside the treatment box 1 is replaced by a replacement mechanism 5. The magnets 4 are installed by a fixing mechanism 6. The replacement mechanism 5 includes a support frame 501, which is fixedly connected to the inner cavity of the treatment box 1. A storage seat 502 is slidably connected to the inner wall of the treatment box 1. A connecting groove 503 is formed on the outer wall of the treatment box 1. A connecting plate 504 is slidably connected to the inner wall of the connecting groove 503. Fixing grooves 505 are formed at the top and bottom of the connecting groove 503. The internal sliding connection includes a fixing block 506 extending from the connecting plate 504. A first spring 507 connects the fixing block 506 and the connecting plate 504. A first spur gear 508 is rotatably connected to the inner wall of the fixing block 506 inside the connecting plate 504. A rotating block 509 is rotatably connected to the outer wall of the connecting plate 504. The first spur gear 508 is fixedly connected to the rotating block 509. The replacement mechanism 5 also includes an installation groove 510. The installation groove 510 is opened at the bottom end of the storage base 502. A filter plate 511 is slidably connected to the inner wall of the installation groove 510. A slot 512 extending into the inner wall of the installation groove 510 is opened on the outer wall of the storage base 502. An insert block 513 is fixedly connected to the outer wall of the connecting plate 504 and inserted into the inner wall of the slot 512.

[0031] In this embodiment: the filter material is stored in the storage seat 502, the sewage enters the treatment box 1 through the feed pipe 2, the filter material removes chromium from the sewage, and the treated sewage is discharged through the discharge pipe 3.

[0032] When replacing the filter material, rotating block 509 is rotated, which drives the first spur gear 508 to rotate. The rotation of the first spur gear 508 causes the fixed block 506 to shift, compressing the first spring 507. The fixed block 506 shifts out of the fixed groove 505, releasing the fixation of the connecting plate 504. The connecting plate 504 can then be removed through the connecting groove 503, allowing the storage seat 502 to be taken out and the filter material inside the storage seat 502 to be replaced. After replacement, the storage seat 502 is placed into the processing box 1, and the support frame 501 positions the storage seat 502. Then, the connecting plate 504 is connected into the connecting groove 503 to fix the storage seat 502. After that, the rotating block 509 is released, and the fixed block 506 is displaced into the fixed groove 505 by the elastic force of the first spring 507, fixing the connecting plate 504. This facilitates the replacement of the filter material and allows the addition of material to the other storage seat 502 while one storage seat 502 is in use, improving the efficiency of filter material replacement.

[0033] When replacing the material in the storage seat 502, the filter plate 511 can be removed from the mounting groove 510 by thread, the material in the storage seat 502 can be taken out, and then the filter plate 511 can be installed into the mounting groove 510. The material is poured into the storage seat 502 and falls onto the filter plate 511 for storage. When installing the connecting plate 504, the insert 513 enters and exits the slot 512. The insert 513 contacts the bottom end of the filter plate 511 to prevent the filter plate 511 from becoming loose during use.

[0034] Please refer to this carefully. Figures 5 to 8The fixing mechanism 6 includes a horizontal plate 601, which is fixedly connected to both sides of the connecting plate 504. Horizontal grooves 602 are provided on both sides of the connecting groove 503. Movable grooves 603 are symmetrically provided on both sides of the outer wall of the processing box 1. A clamping plate 604 is provided inside the movable groove 603. A limiting rod 605, penetrating the clamping plate 604, is fixedly connected to the inner wall of the movable groove 603. A threaded rod 606, penetrating the clamping plate 604, is rotatably connected inside the processing box 1. A second spur gear 607 is fixedly connected to the top of the threaded rod 606 at the top of the processing box 1. The top of the processing box 1 is rotatably connected to the outer wall of the second spur gear 607. The fixing mechanism 6 includes a toothed ring 608 and a fixing seat 609. The fixing seat 609 is fixedly connected to the top of the processing box 1 and located inside the toothed ring 608. A locking block 611 is rotatably connected to the outer wall of the fixing seat 609. A locking groove 610 is opened on the inner wall of the toothed ring 608.

[0035] In this embodiment: when installing the magnet 4, the magnet 4 is placed between two clamping plates 604, and then the gear ring 608 is rotated. The rotation of the gear ring 608 drives the second spur gear 607 to rotate. The rotation of the second spur gear 607 drives the two clamping plates 604 to move closer to each other. The displacement of the clamping plates 604 clamps and fixes the magnet 4. Then the locking block 611 is rotated and enters the locking groove 610 to fix the gear ring 608.

[0036] When the clamping plate 604 is installed, the horizontal plate 601 moves into the horizontal groove 602, and the horizontal plate 601 contacts the pressing block 615, pushing the pressing block 615 to move. The displacement of the pressing block 615 causes the positioning frame 613 to move. The positioning frame 613 engages with the positioning block 612, thereby positioning the positioning block 612 and reinforcing the position of the clamping plate 604 to prevent the magnet 4 from loosening during use, and to facilitate the installation and removal of the magnet 4.

The fixed block 506 moves out of the fixed groove 505, thus canceling the fixation of the connecting plate 504.
