Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically an industrial wastewater treatment device. Background Technology

[0002] There are many types of industrial wastewater treatment equipment, and their design and function depend on the specific industrial process and wastewater type. One example is the activated sludge process, a biological treatment technology widely used in industrial and municipal wastewater treatment. It utilizes the metabolic activity of microorganisms to remove organic matter and nutrients from wastewater. First, pretreatment removes large particles and sediments to prevent damage to subsequent treatment equipment. Then, primary treatment removes suspended solids through sedimentation. Next, biological treatment occurs, where wastewater is fed into a reactor filled with activated sludge. Here, microorganisms consume the organic matter, converting it into harmless substances. Secondary sedimentation separates the activated sludge from the treated water, and some is returned to the biological treatment stage to maintain the microbial concentration in the reactor. Finally, post-treatment may include disinfection, denitrification, and dephosphorization to further improve effluent quality. This is just one common type of industrial wastewater treatment equipment; the actual design may be adjusted based on the specific industrial process and wastewater characteristics.

[0003] Existing wastewater treatment equipment is too expensive and unsuitable for small and medium-sized enterprises. To reduce operating costs, wastewater can be first settled and then filtered. Furthermore, while flocculants are currently used in wastewater treatment, existing equipment cannot ensure thorough mixing between the wastewater and the flocculant, severely impacting the treatment process and its effectiveness. Additionally, filter screens are used during filtration, and prolonged use leads to the accumulation of dirt on their surface, affecting the filtration process and necessitating cleaning and replacement.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1:

[0025] Please refer to Figures 1 to 6 In the embodiments of the present invention:

[0026] An industrial wastewater treatment device includes a base plate 1, on which a sedimentation device is mounted. The sedimentation device includes a sedimentation tank 2, an inlet 3, and a gravel layer 4. The sedimentation tank 2 is located at the top of the base plate 1, and the inlet 3 is located on one side of the top of the sedimentation tank 2. The gravel layer 4 is located inside the sedimentation tank 2. A stirring mechanism is located at one end of the sedimentation tank 2. The stirring mechanism includes a treatment tank 5, a servo motor 6, and a stirring shaft 7. The treatment tank 5 is located at one end of the sedimentation tank 2, and the servo motor 6 is located at the top of the treatment tank 5. The stirring shaft 7 is located at the output end of the servo motor 6. A filtration mechanism is located at the bottom of the treatment tank 5. The filtration mechanism includes filter screens 8, mounting strips 9, and sliding grooves 10. Multiple filter screens 8 are located at the bottom of the treatment tank 5, and the mesh diameter of each filter screen 8 is different. Mounting strips 9 are located on both sides of the filter screens 8, and sliding grooves 10 are located on the sides of the mounting strips 9.

[0027] In this embodiment of the invention: a quartz sand layer 11 is provided at the lower end of the large stone layer 4, a drain pipe 12 is connected to the bottom of one side of the sedimentation tank 2, one end of the drain pipe 12 is connected to the treatment tank 5, a water pump 13 is provided on the drain pipe 12, and a support leg 14 is provided at the bottom of the sedimentation tank 2. Industrial wastewater is fed into the sedimentation tank 2 through the inlet 3, and then filtered through the large stone layer 4 and the quartz sand layer 11, so that large pollutants are filtered out. After filtration, the water flows from the sedimentation tank 2 into the treatment tank 5 through the drain pipe 12 under the action of the water pump 13.

[0028] In this embodiment of the invention: a drive motor 15 is provided at the top of the sedimentation tank 2, and a rotating rod 16 is provided at the output end of the drive motor 15. A scraper 17 is provided at the contact point between the rotating rod 16 and the boulder layer 4 and the quartz sand layer 11. A sewage pipe 18 is provided at multiple points at one end of the sedimentation tank 2. A collection box 19 is connected to one end of the sewage pipe 18. After filtration through the boulder layer 4 and the quartz sand layer 11, the drive motor 15 is started, which drives the rotating rod 16 at the output end to rotate, thereby promoting the scraper 17 to scrape the surface of the boulder layer 4 and the quartz sand layer 11. The scraped-off pollutants are discharged into the collection box 19 along the sewage pipe 18.

[0029] In this embodiment of the invention: a stirring rod 20 is provided on the stirring shaft 7, a reciprocating screw 21 is provided on the stirring shaft 7, a movable tank 22 is provided on the outside of the reciprocating screw 21, and moving blocks 23 are provided at both ends of the movable tank 22. After the wastewater after initial filtration enters the treatment tank 5, the servo motor 6 is started to drive the stirring shaft 7 at the output end to rotate, thereby driving the stirring rod 20 to rotate, further stirring the wastewater inside. During the stirring process, the reciprocating screw 21 drives the movable tank 22 to move up and down using the moving blocks 23.

[0030] In this embodiment of the invention: a through groove 24 is provided at the contact point between the movable block 23 and the treatment tank 5. A pressure plate 25 is provided through the through groove 24. A liquid storage tank 26 is provided at the bottom of the pressure plate 25. A pressure ball 27 and a connecting pipe 28 are provided on the liquid storage tank 26. The connecting pipe 28 is connected to the top of the treatment tank 5. During the up-and-down movement of the movable block 23, the movable block 23 moves within the through groove 24 and drives the pressure plate 25 on one side to move up and down, so that the pressure plate 25 presses the pressure ball 27, increasing its pressure. This causes the flocculant inside the liquid storage tank 26 to flow orderly into the movable tank 22 through the connecting pipe 28, thus completing the wastewater treatment process.

[0031] In this embodiment of the invention: the top of the filter screen 8 is provided with an electric telescopic rod 29, the outer end of the electric telescopic rod 29 is provided with a cleaning door 30, the bottom end of the processing box 5 is provided with an observation window 31, the processed material is discharged to the bottom of the movable tank 22 and filtered by multiple filter screens 8. When it is observed from the external observation window 31 that the internal filter screen 8 needs to be cleaned or replaced, the cleaning door 30 is opened and the electric telescopic rod 29 is activated so that the filter screen 8 slides along the sliding groove 10 using the mounting strips 9 at both ends.

[0032] In this embodiment of the invention: the output end of the electric telescopic rod 29 is provided with an opening 32, and the contact point between the opening 32 and the filter screen 8 is detachably connected with a bolt 33. The filter screen 8 can be removed from the opening 32 for cleaning or replacement by manually turning the bolt 33.

[0033] Example 2:

[0034] refer to Figures 1 to 6 In operation, industrial wastewater is fed into sedimentation tank 2 through inlet 3, where it passes through a layer of large stones 4 and a layer of quartz sand 11 for filtration, removing large pollutants. The filtered water, pumped by pump 13, flows from sedimentation tank 2 into treatment tank 5 through drain pipe 12. After passing through the large stones 4 and quartz sand 11, drive motor 15 is activated, rotating the output rod 16. This causes scraper 17 to scrape the surfaces of the large stones 4 and quartz sand 11, and the scraped pollutants are discharged into collection tank 19 through drain pipe 18. After the initial filtration, the wastewater enters treatment tank 5, where servo motor 6 is activated, rotating the output stirring shaft 7, which in turn rotates the stirring rod 20, further agitating the wastewater. Using the reciprocating screw 21, the movable tank 22 is driven to move up and down using the moving block 23. During the up-and-down movement of the moving block 23, it moves within the through groove 24 and drives the pressure plate 25 on one side to move up and down, causing the pressure plate 25 to press the pressure ball 27, thereby increasing the pressure and causing the flocculant inside the storage tank 26 to flow orderly into the movable tank 22 through the connecting pipe 28, completing the wastewater treatment process. After treatment, the wastewater is discharged to the bottom of the movable tank 22 and filtered through multiple filter screens 8. When it is observed from the external observation window 31 that the internal filter screens 8 need to be cleaned or replaced, the cleaning door 30 is opened, and the electric telescopic rod 29 is activated, causing the filter screens 8 to slide along the sliding groove 10 using the mounting strips 9 at both ends. The filter screens 8 are then removed from the opening 32 by manually turning the bolts 33 for cleaning or replacement.

[0035] In all the solutions mentioned above, for connections between two components, welding, bolt and nut connection, bolt or screw connection, or other known connection methods can be selected according to the actual situation. These will not be elaborated here. For all fixed connections mentioned above, welding is preferred. The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
