Description

Technical Field

[0001] This utility model relates to the field of silicon-containing wastewater treatment technology, specifically to a flocculation sedimentation tank for silicon-containing wastewater. Background Technology

[0002] Silicon-containing wastewater refers to wastewater containing silicon compounds, which can include dissolved silicates, colloidal silicon, and other forms of silicon. Silicon wastewater is typically generated in semiconductor manufacturing, glass production, and other industrial processes. Because silicon compounds can have an impact on the environment and water treatment systems, it is crucial to treat and manage them. Commonly used methods include chemical precipitation, adsorption, and membrane separation technologies to remove or recover silicon compounds, thereby achieving the goals of environmental protection and resource utilization.

[0003] In current silicon-containing wastewater treatment processes, most still rely on a single flocculation and sedimentation process. This not only fails to effectively pre-filter impurities in the wastewater, but also fails to allow for multiple flocculation and sedimentation processes for silicon-containing wastewater. This results in the wastewater not being fully treated, thereby reducing the efficiency of flocculation and sedimentation of silicon-containing wastewater and the overall treatment quality. To solve the above problems, we propose a flocculation sedimentation tank for silicon-containing wastewater. Utility Model Content

[0004] The purpose of this invention is to provide a flocculation sedimentation tank for silicon-containing wastewater to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flocculation sedimentation tank for silicon-containing wastewater, comprising a treatment tank, a filter box fixedly connected to one side of the treatment tank, a water inlet on the top of the filter box, a feed inlet on one side of the treatment tank, stirring blades rotatably connected between the inner walls of the treatment tank, a stirring assembly on the top of the treatment tank for driving the stirring blades to rotate, a storage tank fixedly connected to the bottom of the treatment tank, a through groove on the bottom inner side of the treatment tank communicating with the interior of the storage tank, baffles slidably connected between the inner walls of the treatment tank, a connecting pipe fixedly connected between the treatment tank and the storage tank, the connecting pipe communicating with the interior of the treatment tank, the bottom end of the connecting pipe extending into the interior of the storage tank, and a waste discharge port on one side of the storage tank.

[0013] This utility model provides a flocculation sedimentation tank for silicon-containing wastewater, which has the following beneficial effects:

[0014] (1) The present invention uses a first filter frame set inside the first chute to facilitate the pre-filtration and collection of impurities in wastewater. At the same time, the second filter frame inside the second chute is used to filter and collect the sediment again. The wastewater after one treatment is pumped back to the treatment tank through the connecting pipe, thereby realizing multiple flocculation and sedimentation treatments, ensuring that the silicon-containing wastewater is fully flocculated and precipitated, thereby effectively improving the efficiency of flocculation and sedimentation and the overall treatment quality.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a flocculation sedimentation tank for silicon-containing wastewater includes a treatment tank 1. A filter box 2 is fixedly connected to one side of the treatment tank 1, and a water inlet 4 is provided on the top of the filter box 2. A feed inlet 6 is provided on one side of the treatment tank 1. A stirring blade 15 is rotatably connected between the inner walls of the treatment tank 1. A stirring assembly is provided on the top of the treatment tank 1 to drive the stirring blade 15 to rotate. A storage tank 3 is fixedly connected to the bottom of the treatment tank 1. A through groove 16 is provided at the bottom of the inner side of the treatment tank 1, and the through groove 16 communicates with the interior of the storage tank 3. A baffle 17 is slidably connected between the inner walls of the treatment tank 1. A connecting pipe 19 is fixedly connected between the treatment tank 1 and the storage tank 3. The connecting pipe 19 is connected to the interior of the treatment tank 1. The bottom end of the connecting pipe 19 extends into the interior of the storage tank 3. A waste outlet 7 is provided on one side of the storage tank 3. A first chute 21 is provided on one side of the filter box 2. A first filter frame 5 is slidably connected between the inner walls of the first chute 21. A second chute 22 is provided on one side of the storage tank 3. A second filter frame 8 is slidably connected between the inner walls of the second chute 22. A connecting rod 18 is fixedly connected to one side of the baffle 17. One end of the connecting rod 18 extends to the outside of the treatment tank 1 and is fixedly connected to a handle 23. A water pump 20 is fixedly installed between the inner walls of the storage tank 3. The output end of the water pump 20 is fixedly connected to the extension end of the connecting pipe 19.

[0023] When treating silicon-containing wastewater, the wastewater is first injected into the filter tank 2 through the water inlet 4. After passing through the first filter frame 5 (a filter plate made of stainless steel is installed on one side of the first filter frame 5 to pre-filter impurities), the wastewater flows into the treatment tank 1. Then, flocculant (specifically, iron salt flocculant, which can react with the silicon components in the wastewater to form iron silicate precipitate) is injected into the treatment tank 1 through the feed inlet 6. Immediately afterwards, the stirring assembly drives the stirring blades 15 to rotate between the inner walls of the treatment tank 1 to promote the reaction of the flocculant with the silicon components in the wastewater to form precipitate. Then, the handle is pulled. 23. Drive the connecting rod 18 to move the baffle 17, thereby opening the through channel 16. The wastewater and sediment after primary treatment flow into the storage tank 3, and the sediment is filtered and collected by the second filter frame 8 (a filter plate is provided on one side of the second filter frame 8, and the filter plate is made of stainless steel). At the same time, push the handle 23 again to drive the connecting rod 18 to move the baffle 17 to close the through channel 16. Then, the wastewater after primary treatment is transported back to the treatment tank 1 by the water pump 20 along the connecting pipe 19 to achieve multiple flocculation and sedimentation of the silicon-containing wastewater. Finally, it is safely discharged through the waste outlet 7.

[0024] After the wastewater has completed flocculation and sedimentation, the first filter frame 5 and the second filter frame 8 are respectively removed from the first chute 21 and the second chute 22 for easy cleaning and maintenance, so as to improve the efficiency of the flocculation sedimentation tank.

[0025] like Figures 1-4 As shown, the stirring assembly includes a stirring rod 14, which is rotatably connected to the top of the inner side of the treatment tank 1. The outer side of the stirring rod 14 is fixedly connected to the stirring blade 15. The bottom end of the stirring rod 14 extends to the top of the treatment tank 1 and is fixedly connected to a worm gear 12. The top of the treatment tank 1 is fixedly connected to a mounting plate 9 and an auxiliary plate 10. A worm gear 11 is rotatably connected between the mounting plate 9 and the auxiliary plate 10. The worm gear 11 meshes with the worm gear 12. A stirring motor 13 is fixedly installed on one side of the mounting plate 9. The output end of the stirring motor 13 passes through the mounting plate 9 and is fixedly connected to the worm gear 11.

[0026] The stirring motor 13 drives the worm gear 11 to rotate between the mounting plate 9 and the auxiliary plate 10. Then, through the meshing between the worm gear 11 and the worm wheel 12, the stirring rod 14 drives the stirring blade 15 to rotate between the inner walls of the treatment tank 1, thereby improving the efficiency of flocculation and sedimentation of silicon-containing wastewater.

[0027] This utility model provides a flocculation sedimentation tank for silicon-containing wastewater. The specific working principle is as follows: When treating silicon-containing wastewater, wastewater is first injected into the filter box 2 through the water inlet 4. After impurities are pre-filtered by the first filter frame 5, the wastewater flows into the treatment tank 1. Subsequently, flocculant is injected into the treatment tank 1 through the feed inlet 6. Next, the stirring motor 13 drives the worm gear 11 to rotate between the mounting plate 9 and the auxiliary plate 10. Then, through the meshing of the worm gear 11 and the worm wheel 12, the stirring rod 14 drives the stirring blades 15 to rotate within the inner wall of the treatment tank 1, thereby promoting the flocculation sedimentation. The flocculant reacts with the silicon components in the wastewater to form precipitates. Then, pulling the handle 23 drives the connecting rod 18 to move the baffle 17, thereby opening the channel 16. The wastewater and precipitates after the first treatment flow into the storage tank 3, and the precipitates are filtered and collected through the second filter frame 8. At the same time, pushing the handle 23 again drives the connecting rod 18 to move the baffle 17 to close the channel 16. Subsequently, the wastewater after the first treatment is transported back to the treatment tank 1 through the water pump 20 along the connecting pipe 19 to achieve multiple flocculation and sedimentation of the silicon-containing wastewater. Finally, it is safely discharged through the waste outlet 7.

[0028] After the wastewater has completed flocculation and sedimentation, the first filter frame 5 and the second filter frame 8 are respectively removed from the first chute 21 and the second chute 22 for easy cleaning and maintenance, so that they can be used later. This completes the use of the flocculation sedimentation tank.

[0029] 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.
