Description

Technical Field

[0001] This utility model relates to the field of dyeing and printing wastewater treatment technology, specifically to a device for removing heavy metal ions from dyeing and printing wastewater. Background Technology

[0002] As is well known, existing treatment devices for heavy metal ion treatment in dyeing and printing wastewater have many limitations in practical applications. On the one hand, the installation and disassembly of adsorption components are cumbersome, often requiring complex tools and numerous steps, consuming significant manpower and time, and potentially affecting subsequent treatment results due to improper assembly. On the other hand, traditional devices typically only have a single adsorption component for filtration. When this component needs to be disassembled and cleaned after long-term use, the entire wastewater treatment process must be stopped, leading to interruption of treatment and hindering continuous and stable wastewater treatment, thus affecting treatment efficiency. Furthermore, in some devices, the mixing of reagents and wastewater, as well as their coordination with the adsorption components, is not sufficiently optimized, making it difficult to fully convert heavy metal ions into easily captured forms and effectively remove them through the adsorption components. This results in poor heavy metal ion removal efficiency, failing to meet the actual needs of dyeing and printing wastewater treatment. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a device for removing heavy metal ions from dyeing and printing wastewater, which has the following beneficial effects: This heavy metal ion removal device for dyeing and printing wastewater facilitates rapid assembly and disassembly of the adsorption components. Through the fitting and positioning of the splicing groove and fastening plate, combined with the synergistic action of the adjusting shaft, gears, bidirectional lead screw, fastening blocks, and fastening columns, rotating the adjusting shaft allows the fastening columns to engage or disengage from the fastening holes, thus completing the installation or disassembly of the adsorption components. No complex tools are required, making operation simple and quick, saving labor and time costs. Multiple adsorption mechanisms arranged in a ring array enable alternating filtration operations. While one adsorption component is filtering in the treatment chamber, operators can prepare to assemble other adsorption components. When the currently operating adsorption component needs cleaning, the drive motor rotates the rotating shaft, allowing other adsorption components to be rotated into the treatment chamber for vertical placement and continued filtration. At this time, the adsorption component requiring cleaning can be disassembled and cleaned without stopping the overall treatment process, ensuring the continuity of dyeing and printing wastewater treatment and improving treatment efficiency.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4This utility model relates to a device for removing heavy metal ions from dyeing and printing wastewater, comprising a treatment tank 1, a treatment cavity 2 at the top of the treatment tank 1, an external connection mechanism, a chemical supply mechanism, and an adsorption mechanism on the treatment tank 1, the adsorption mechanism comprising a rotating shaft 3 and an adsorption assembly 4, bearing seats 5 between the two ends of the rotating shaft 3 and the treatment tank 1, a drive motor 6 between one of the bearing seats 5 and the rotating shaft 3, a splicing groove at the top of the adsorption assembly 4, a fastening hole 8 at one end of the splicing groove, two splicing grooves symmetrically arranged, a splicing plate 7 on the outer side of the rotating shaft 3, and fastening plates 9 on both sides of the bottom end of the splicing plate 7. An adjustment box 10 is provided on one side of the splicing plate 7. The interior of the adjustment box 10 is connected to the interior of the splicing plate 7. An adjustment shaft 11 is provided between the interior of the adjustment box 10 and one side. A bidirectional lead screw 12 is provided inside the splicing plate 7. Fastening blocks 13 are provided at both ends of the bidirectional lead screw 12. Threaded holes are opened on the fastening blocks 13, through which the bidirectional lead screw 12 passes. A fastening post 18 is provided at the bottom end of the fastening blocks 13, extending to the outside of the fastening plate 9. Gears 14 are provided on both the bidirectional lead screw 12 and the adjustment shaft 11. Two gears 14 mesh and abut against each other. Multiple adsorption mechanisms are provided and arranged in a circular array. In the example, depending on the type of heavy metal in the dyeing and printing wastewater to be treated, such as copper-containing wastewater, modified zeolite adsorption component 4 is selected, and chitosan adsorption component 4 is selected for chromium-containing wastewater. The splicing groove of the adsorption component 4 is aligned with the fastening plate 9 at the bottom of the splicing plate 7, and pushed axially until the splicing groove and the fastening plate 9 are fully engaged. The adjusting shaft 11 on the outside of the adjusting box 10 is rotated. The adjusting shaft 11 drives the bidirectional lead screw 12 to rotate through the meshing gear 14. The bidirectional lead screw 12 passes through the threaded holes of the two fastening blocks 13. The forward rotation of the bidirectional lead screw 12 causes the fastening blocks 13 with threaded holes at both ends to move along the lead screw to both ends. This causes the fastening post 18 at the bottom of the fastening block 13 to extend out of the outside of the fastening plate 9 and insert into the fastening hole at the splicing groove end of the adsorption component 4. In step 8, the tightness can be confirmed by touch or torque wrench until the fastening column 18 and the fastening hole 8 are completely fitted, thereby achieving rapid assembly of the adsorption component 4. Then, the output end of the drive motor 6 is controlled to rotate the rotating shaft 3. The rotating shaft 3 drives the filter group to select the angle through two bearing seats 5. The filter component can be placed vertically in the treatment chamber 2 of the treatment box 1. The filter component can be adapted to the size of the treatment chamber 2, which can divide the air inside the treatment chamber 2 into two, thereby achieving stable and efficient filtration of heavy metal substances in the dyeing and printing wastewater. Since there are multiple adsorption mechanisms arranged in a ring array, when one adsorption component 4 is performing filtration, the staff can prepare to assemble other adsorption components 4.After prolonged use, the adsorption component 4 will accumulate impurities and foreign objects, requiring disassembly and cleaning. To address this, the output of the drive motor 6 rotates the rotating shaft 3, causing other filter components to be placed vertically in the treatment chamber 2, enabling alternating filtration. The filter component that previously filtered accumulated impurities can then be disassembled and cleaned. Reverse rotation of the adjusting shaft 11 moves the bidirectional lead screw 12 linearly towards the center position, disengaging the fastening column 18 from the fastening hole 8 and removing the fastening plate 9 from the splicing groove, allowing for quick removal of the filter component. The chemical supply mechanism is then activated, delivering chemicals such as sodium sulfide and PAM to the treatment chamber 2. The chemicals mix with the wastewater, and through a chemical reaction, heavy metal ions are converted into easily captured forms. Combined with the physical adsorption of the adsorption component 4, this achieves highly efficient adsorption of heavy metal impurity particles.

[0016] To facilitate the connection of external pipes 15, in this solution, the external connection mechanism includes external pipes 15, which are installed at both ends of the treatment tank 1. The external pipes 15 are used to connect the treatment tank 1 to the external wastewater conveying pipeline. One external pipe 15 is used for water inlet, and the other external pipe 15 is used for water outlet.

[0017] To facilitate the supply of the chemical solution, the chemical supply mechanism in this design includes a chemical supply pipe 16. The chemical supply pipe 16 is installed on the outside of the treatment tank 1 and extends into the treatment chamber 2. External chemical containers, such as sodium sulfide and PAM, are connected to the treatment chamber 2 via the chemical supply pipe 16, preventing oxidation of the chemicals upon contact with air during transport and ensuring their activity. Simultaneously, it allows for precise control of the chemical delivery position, improving reaction efficiency. Two chemical supply pipes 16 are provided and symmetrically arranged. This symmetrical layout ensures uniform distribution of the chemicals within the treatment chamber 2, resolving the issue of excessively high or low local chemical concentrations caused by a single chemical supply pipe 16, and improving the uniformity of the mixing between the chemicals and wastewater.

[0018] To facilitate the connection of external pipelines, in this design, both the external pipe 15 and the drug supply pipe 16 are equipped with flanges 17, and the pipeline and the treatment box 1 are sealed and fastened by bolt connection of the flanges 17.

[0019] In order to adjust the rotation speed of the rotating shaft 3 with high precision, the drive motor 6 in this solution is a servo motor. The servo motor can precisely adjust the rotation speed and has an overload protection function. It can adjust the rotation angle of the adsorption component 4 according to the heavy metal concentration of the wastewater.

[0020] In order to facilitate the stabilization of the fastening plate 9 in the splicing groove, in this solution, both the fastening plate 9 and the splicing groove are T-shaped structures. The T-shaped structure forms a limiting fit in the upper, lower, left and right directions to prevent the adsorption component 4 from moving along the axial or radial direction.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
