Description

Technical Field

[0001] This utility model relates to the field of chemical wastewater treatment technology, specifically to an internal circulation micro-electrolysis anaerobic reactor chemical wastewater treatment device. Background Technology

[0002] Iron-carbon micro-electrolysis technology is widely used in wastewater treatment in industries such as printing and dyeing, chemical industry, and pharmaceutical industry. When the wastewater to be treated passes through the micro-electrolysis packing, the active iron will form the anode and the inert carbon will form the cathode. This will form countless micro-galvanic cells in the wastewater, and a series of electrochemical oxidation-reduction reactions will occur at the two poles of the micro-galvanic cells, thereby achieving the purpose of degrading pollutants in the wastewater.

[0003] Most wastewater treatment methods involve adding flocculants to purify the wastewater, causing suspended solids and colloidal particles to form flocs that settle. However, if these flocs accumulate on the filter plates or adhere to the surface of the micro-electrolysis packing material, they can clog the filter plates and packing material, thus reducing the treatment efficiency. Therefore, there is an urgent need to design an internal circulation micro-electrolysis anaerobic reactor for chemical wastewater treatment to address these issues. Utility Model Content

[0029] In this embodiment, a processing box 1 is included, and two frames 2 and a filter layer 3 are sequentially installed inside the processing box 1.

[0030] Specifically, a second screw 18 is rotatably fitted at the lower front end of the processing box 1. The second screw 18 is threadedly fitted to one end of multiple baffles 17. Two motors 19 are installed on one side of the processing box 1. The second screw 18 is threadedly fitted to multiple baffles 17, thereby driving multiple baffles 17 to move horizontally in sync, which can open multiple discharge ports 16.

[0031] Specifically, the output end of one motor 19 is fixed to one end of the second screw 18, the output end of the other motor 19 is fixed to one end of the rotating rod 13, and the lower end of the processing box 1 is equipped with a collection box 20 corresponding to multiple baffles 17. Through the collection box 20, the cleaned flocs can be guided into the collection box 20 for collection and storage.

[0032] In this embodiment, multiple first filter holes 4 and multiple second filter holes 5 are provided on the opposite sides of the two frames 2. Filter packing and micro-electrolysis packing are installed inside the two frames 2. Multiple water pipes 6 corresponding to the filter packing and micro-electrolysis packing are installed inside the two frames 2. Openings 7 are provided on the periphery of the multiple water pipes 6.

[0033] Specifically, two inlets 21 and an outlet 22 are respectively opened on opposite sides of the treatment box 1. A water guide is opened on the rear side of the treatment box 1. Valves are installed in the two inlets 21, the outlet 22, and the water guide. Wastewater and flocculant can be introduced into the treatment box 1 through the two inlets 21 to prepare for the next step of purifying the wastewater.

[0034] Specifically, pipes 23 are provided at both inlets 21 and outlets 22. One end of the transmission pipe 11 is located inside the water inlet, and a water pump is installed at one end of the transmission pipe 11. The water inlet is located at the bottom of the rear side of the treatment tank 1 and corresponds to the filter layer 3. The purified wastewater can be introduced into the two frames 2 through the water pump to rinse the filter media and micro-electrolysis media, and can be recycled and reused.

[0035] In this embodiment, two grooves 8 are provided on the inner side of the treatment box 1. A first screw 9 is rotatably fitted in each of the two grooves 8. A U-shaped cleaning brush 10 corresponding to the frame 2 is threaded on the periphery of each of the two first screws 9. A transmission pipe 11 is connected between the other end of the treatment box 1 and multiple water pipes 6. A drive assembly that is connected to the two first screws 9 is installed at the lower end of the treatment box 1.

[0036] Specifically, the drive assembly includes a first bevel gear 12 respectively mounted on the lower end of the two first screws 9, a rotating rod 13 rotatably engaged with the lower rear end of the processing box 1, and two second bevel gears 14 mounted on the periphery of the rotating rod 13 and meshing with the two first bevel gears 12. The diameter of the first filter hole 4 is larger than the diameter of the second filter hole 5. The rotating rod 13 can drive the two second bevel gears 14 to rotate, so that the two second bevel gears 14 mesh with the two first bevel gears 12 and rotate, thereby driving the two first screws 9 to rotate synchronously, in preparation for the next step of cleaning the two frames 2.

[0037] Specifically, the U-shaped cleaning brush 10 is slidably fitted on the opposite sides of the frame 2 and corresponds to multiple first filter holes 4 and multiple second filter holes 5. The opposite inner sides of the two grooves 8 are elastically fitted with rubber blocks 15. Through the multiple rubber blocks 15, multiple adjacent rubber blocks 15 are always in contact with one end of the U-shaped cleaning brush 10, thereby sealing the two grooves 8.

[0038] Specifically, two adjacent rubber blocks 15 are attached to one end of the U-shaped cleaning brush 10. Multiple discharge ports 16 are provided inside the lower end of the treatment box 1. Each discharge port 16 is slidably fitted with a baffle 17. The cleaned lint can be discharged out of the treatment box 1 through the multiple discharge ports 16.

[0039] Working steps: 1. When wastewater needs to be purified, first open the valves at the two inlets 21 and put the wastewater and flocculant into the treatment tank 1. At this time, the wastewater and flocculant mix and react, which can form flocs and precipitate the suspended solids and colloidal particles in the wastewater, thus achieving solid-liquid separation. At the same time, the separated wastewater is intercepted and filtered through multiple first filter holes 4, filter packing, and multiple second filter holes 5. Then, the filtered wastewater enters a frame 2 through multiple first filter holes 4. At this time, the micro-electrolysis packing purifies and degrades the pollutants in the filtered wastewater. At the same time, the purified wastewater is filtered again through multiple second filter holes 5 and filter layer 3 to achieve wastewater purification. Biogas is generated during the wastewater purification process. At this time, open the valve at the gas outlet 22, and the biogas is discharged outside the treatment tank 1 through the pipe 23.

[0040] 2. When it is necessary to rinse the filter media and micro-electrolysis media, open the valve at the water inlet and start the water pump. The purified wastewater can be introduced into multiple water pipes 6 through the transmission pipe 11 and flow out through multiple openings 7, thereby rinsing the flocs adhering to the surface of the filter media and micro-electrolysis media. At the same time, the outflowing water is filtered and purified through multiple first filter holes 4, multiple second filter holes 5, and filter layer 3, thereby realizing the reuse of water circulation.

[0041] 3. When cleaning multiple first filter holes 4 and multiple second filter holes 5 is required, another motor 19 is started. The output end of the other motor 19 drives the rotating rod 13 to rotate, causing the rotating rod 13 to drive the two second bevel gears 14 to rotate. Thus, the two second bevel gears 14 mesh with the two first bevel gears 12 and rotate, which can drive the two first screws 9 to rotate synchronously. This allows the two first screws 9 to engage with the two U-shaped cleaning brushes 10, thereby driving the two U-shaped cleaning brushes 10 to move up and down on opposite sides of the two frames 2, which can clean the lint adhering to the multiple first filter holes 4 and multiple second filter holes 5. At this time, multiple adjacent rubber blocks 15 are always in contact with one end of the two U-shaped cleaning brushes 10. At the same time, one of its motors 19 is turned on, and the output end of the motor 19 drives the second screw 18 to rotate, causing the second screw 18 to engage with multiple baffles 17, thereby driving the multiple baffles 17 to move horizontally synchronously, which can open multiple discharge ports 16. At this time, the lint swept down falls into the collection box 20 for collection and storage.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
