Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment mechanism for high-voltage anode electrode foil production. Background Technology

[0002] Wastewater from high-voltage anode electrode foil production is a complex industrial wastewater with high pollutant concentrations and high toxicity, generated during metal surface treatment (especially aluminum, magnesium, and titanium alloys). It primarily originates from wastewater and rinsing water from pretreatment processes (degreasing, alkaline etching, acid pickling), oxidation, dyeing, and sealing. A chemical precipitation method is employed, using alkali to neutralize and form heavy metal hydroxide precipitates, supplemented by coagulation and flocculation (PAC / PAM) to enhance precipitation separation. After pretreatment, filtration continues. Wastewater filtration technology is an indispensable physical separation method in water treatment, primarily using filter media with specific pore structures to trap suspended solids, colloids, particulate matter, and some microorganisms and even large organic molecules in the water. When wastewater flows through the media, pollutants larger than the pore size are directly blocked on the media surface or within the pores, achieving solid-liquid separation and laying the foundation for subsequent advanced treatment (such as disinfection and reverse osmosis) or achieving compliant discharge / reuse. Wastewater treatment equipment is a key component in the water treatment process for improving water quality. It effectively removes suspended solids, colloids, some microorganisms, and even dissolved pollutants from wastewater through mechanisms such as physical interception and adsorption.

[0003] Existing wastewater treatment facilities for high-voltage anode electrode foil production inject wastewater through an inlet. The wastewater undergoes filtration through multiple filters from high to low pressure before being discharged through an outlet. For highly polluted wastewater, only one filtration process is performed. If the wastewater does not meet national emission standards, multiple filtration cycles are required, necessitating manual intervention to re-inject the wastewater into the inlet.

[0004] It wastes manpower, and the wastewater can also affect the health of the staff. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wastewater treatment mechanism for high-voltage anode electrode foil production, which aims to improve the problem that wastewater with a high degree of pollution may not meet the discharge standards after passing through a primary filtration device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment mechanism for high-voltage anode electrode foil production, comprising a body, a base fixedly connected to the bottom of the body, a top cover fixedly connected to the top of the body, and a wastewater circulation mechanism disposed on the other side of the base. The wastewater circulation mechanism includes a water pump disposed on one side of the base, a return valve fixedly connected to the input end of the water pump, a first return pipe fixedly connected to one end of the return valve, one end of the first return pipe fixedly connected to the other side of the base, a second return pipe fixedly connected to the output end of the water pump, one end of the second return pipe fixedly connected to the top of the top cover, a filter cleaning assembly disposed inside the base, and a filter assembly disposed inside the body.

[0007] Furthermore, the filter cleaning assembly includes a cleaning base plate, the bottom of which is fixedly connected to the inside of the base, a cleaning pipe is fixedly connected to one side of the cleaning base plate, the middle of which is fixedly connected to the inside of the outer wall of the base, and a cleaning valve is fixedly connected to one end of the cleaning pipe.

[0008] Furthermore, the filter assembly includes a first filter screen, which is fixedly connected to the upper side of the inner wall of the machine body, and a second filter screen is fixedly connected to the lower side of the inner wall of the machine body.

[0009] Furthermore, a drain pipe is fixedly connected to the lower side of the outer wall of the machine body, and a drain valve is fixedly connected to one end of the drain pipe.

[0010] Furthermore, a water inlet pipe is fixedly connected to one side of the top cover, and a water inlet valve is fixedly connected to one end of the water inlet pipe. A water outlet pipe is fixedly connected to one side of the base, and a water outlet valve is fixedly connected to one end of the water outlet pipe.

[0011] Furthermore, the four corners of the outer wall of the base are fixedly connected with anti-slip feet.

[0012] Furthermore, multiple cleaning nozzles are fixedly connected to the upper surface of the cleaning base plate.

[0013] Furthermore, a buffer baffle is fixedly connected to the middle side of the inner wall of the fuselage.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this invention, highly polluted wastewater, after being filtered by the first and second filters inside the machine body, has its outlet valve closed. Driven by the water pump, the wastewater flows through the open return valve, through the first return pipe, into the pump, then into the second return pipe, returning to the top cover, and re-entering the machine body for filtration. This circulation system ensures that wastewater of varying pollution levels undergoes multiple cycles of treatment, ultimately meeting the wastewater treatment standards.

[0016] 2. In this utility model, when the second filter screen becomes clogged after multiple filtrations, the cleaning valve and the drain valve are opened, and clean water flows into the cleaning pipe and then into the cleaning base plate. The cleaning nozzle cleans the second filter screen, and the wastewater after cleaning is discharged from the drain pipe, thus completing the cleaning of the second filter screen. It is not necessary to disassemble the equipment to clean the second filter screen, saving time and improving work efficiency. Attached Figure Description

[0024] 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.

[0025] Reference Figures 1-2This utility model provides an embodiment of a high-voltage anode electrode foil production wastewater treatment mechanism, including a body 1, a base 11 fixedly connected to the bottom of the body 1, and a top cover 2 fixedly connected to the top of the body 1. The upper and lower sides of the body 1, the top of the base 11, and the bottom of the top cover 2 form the main body of the wastewater treatment mechanism. A water inlet pipe 3 is fixedly connected to one side of the top cover 2, through which wastewater enters. A water inlet valve 4 is fixedly connected to one end of the water inlet pipe 3, which controls whether wastewater enters the water inlet pipe 3. A water outlet pipe 5 is fixedly connected to one side of the base 11, through which filtered wastewater that meets the standards can be discharged. A water outlet valve 6 is fixedly connected to one end of the water outlet pipe 5, which controls whether wastewater is discharged from the water outlet pipe 5. Anti-slip feet 12 are fixedly connected to the four corners of the outer wall of the base 11, which provide support and anti-slip function. A wastewater circulation mechanism is provided on the other side of the base 11. The wastewater circulation mechanism includes a water pump 9, which is externally powered and located on one side of the base 11. A return valve 8 is fixedly connected to the input end of the water pump 9, and a first return pipe 7 is fixedly connected to one end of the return valve 8. The return valve 8 controls whether wastewater enters the first return pipe 7. One end of the first return pipe 7 is fixedly connected to the other side of the base 11. A second return pipe 10 is fixedly connected to the output end of the water pump 9, and one end of the second return pipe 10 is fixedly connected to the top of the top cover 2. If multiple circulation processes are required, the outlet valve 6 is closed and the return valve 8 is opened. Under the action of the water pump 9, wastewater enters the water pump 9 from the first return pipe 7, then enters the second return pipe 10 from the water pump 9, and returns upwards to the top cover 2 along the second return pipe 10. A filter cleaning assembly is installed inside the base 11, and a filter assembly is installed inside the body 1.

[0026] Reference Figures 1-3 The filter cleaning assembly includes a cleaning base plate 17, which is the main body of the filter cleaning assembly. The bottom of the cleaning base plate 17 is fixedly connected to the inside of the base 11. A cleaning pipe 15 is fixedly connected to one side of the cleaning base plate 17. Clean water is introduced from the outside through the cleaning pipe 15. The middle part of the cleaning pipe 15 is fixedly connected to the inside of the outer wall of the base 11. A cleaning valve 16 is fixedly connected to one end of the cleaning pipe 15. Multiple cleaning nozzles 18 are fixedly connected to the upper surface of the cleaning base plate 17. A drain pipe 13 is fixedly connected to the lower side of the outer wall of the body 1. A drain valve 14 is fixedly connected to one end of the drain pipe 13. When the second filter screen 21 is clogged, the valves except for the cleaning valve 16 and the drain valve 14 are closed. Clean water flows from the cleaning valve 16 into the cleaning pipe 15, and then into the cleaning base plate 17. The second filter screen 21 is cleaned through the cleaning nozzles 18. The wastewater after cleaning is discharged from the drain pipe 13 through the drain valve 14.

[0027] Reference Figures 4-5The filter assembly includes a first filter screen 19, through which wastewater undergoes a first filtration. The first filter screen 19 is fixedly connected to the upper side of the inner wall of the body 1. A second filter screen 21 is fixedly connected to the lower side of the inner wall of the body 1, through which wastewater undergoes a second filtration. A buffer baffle 20 is fixedly connected to the middle side of the inner wall of the body 1. After the first filtration, the wastewater slowly flows downward inside the body 1 under the buffering effect of the buffer baffle 20. After the second filtration, it enters the base 11.

[0028] Working principle: When a high-voltage anode electrode foil production wastewater treatment mechanism is needed for wastewater treatment, the outer wall of the base 11 has four anti-slip feet 12. The upper side of the base 11 is connected to the lower side of the body 1, and the upper side of the body 1 is connected to the lower side of the top cover 2. The upper and lower sides of the body 1, together with the upper part of the base 11 and the lower part of the top cover 2, form the main body of the wastewater treatment mechanism. Wastewater enters the top cover 2 through the inlet pipe 3 after passing through the open inlet valve 4, and then enters the body 1. The wastewater undergoes the first filtration through the first filter screen 19, and under the buffering effect of the buffer baffle 20, it slowly flows downward inside the body 1. After a second filtration through the second filter screen 21, the treated wastewater enters the base 11. To discharge the treated wastewater directly, open the outlet valve 6, and the wastewater will drain from the outlet pipe 5. If multiple cycles are required, close the outlet valve 6 and open the return valve 8. Under the action of the water pump 9, the wastewater enters the water pump 9 from the first return pipe 7, then enters the second return pipe 10, and returns upwards along the second return pipe 10 to the top cover 2. The filtration process continues again. After multiple filtrations to achieve the desired effect, the outlet valve 6 can be opened, and the wastewater will drain from the outlet pipe 5. When the second filter screen 21 becomes clogged, close the inlet valve 4, outlet valve 6, and return valve 8, and open the cleaning valve 16 and drain valve 14. Clean water flows from the cleaning valve 16 into the cleaning pipe 15, then into the cleaning base plate 17, and cleans the second filter screen 21 through the cleaning nozzle 18. The cleaned wastewater is then discharged from the drain pipe 13 through the drain valve 14, completing the cleaning of the second filter screen 21. During the filtration process, cleaning valve 16 and drain valve 14 are in the closed state.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
