Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a chemical wastewater treatment device based on electrocoagulation. Background Technology

[0002] Chemical wastewater refers to industrial wastewater, cooling water, exhaust gas scrubbing water, equipment and site washing water, etc. discharged during chemical production. In order to prevent chemical wastewater from being directly discharged into the environment and causing water bodies to be polluted to varying degrees, thereby endangering human health and affecting industrial and agricultural production, chemical wastewater needs to be treated accordingly. Electrocoagulation is used to replace the traditional chemical coagulation process. By electrolyzing the wastewater in an electrolytic cell, the treatment cost can be reduced and the efficiency can be improved.

[0003] The patent with authorization announcement number CN221344275U discloses a chemical wastewater treatment device based on electrocoagulation, which includes a treatment tank, electrodes fixedly installed inside the treatment tank, an extraction pump fixedly installed at the upper end of the treatment tank, and a discharge pump located on the left side of the treatment tank. This chemical wastewater treatment device based on electrocoagulation can electrolyze and flocculate wastewater through electrodes, thereby enabling the coagulation and sedimentation of impurities in the wastewater.

[0004] However, the above patents still have the following problems: due to the large amount of waste precipitation during the electrocoagulation reaction, the waste will adhere to the surface of the electrode rod during the precipitation process. If the electrode rod set in the reaction tank is not cleaned in time after long-term use, the waste on the surface of the electrode rod will become thicker and thicker, which will directly affect the reaction efficiency of the electrode rod. Therefore, in order to solve the above problems, a chemical wastewater treatment device based on electrocoagulation is proposed. Utility Model Content

[0023] Example

[0024] like Figure 1-4As shown, a chemical wastewater treatment device based on electrocoagulation includes a support leg 1 and a housing 2. The housing 2 is fixedly connected to the top of the support leg 1. A discharge valve 4 is connected to one end of the housing 2. A pump 3 is fixedly connected to one end of the housing 2, and one end of the pump 3 is connected to the housing 2. A stirring rod 5 is rotatably connected to the inside of the housing 2. An end cap 6 is spirally connected to the top of the housing 2. A connecting column 7 is fixedly connected to the bottom of the end cap 6. An electrode rod 8 is fixedly connected to the bottom of the connecting column 7. A cleaning mechanism is provided on the outside of the electrode rod 8.

[0025] As a further improvement to this utility model, such as Figure 2 and Figure 4 As shown, the cleaning mechanism includes a scraper ring 14 slidably connected to the electrode rod 8. A connecting plate 13 is provided on the outer side of the scraper ring 14. A locking component is provided between the connecting plate 13 and the scraper ring 14. A pushing component is provided at the top of the connecting plate 13, and one end of the pushing component is fixedly connected to the end cover 6. When it is necessary to clean the waste on the surface of the electrode rod 8, the scraper ring 14 moves vertically along the electrode rod 8 to scrape off the waste on the surface of the electrode rod 8, preventing the waste from accumulating on the surface of the electrode rod 8. At the same time, manual cleaning is not required, which is convenient for workers to use. The number of scraper rings 14 is the same as the number of electrode rods 8, ensuring that each electrode rod 8 can be cleaned.

[0026] As a further improvement to this utility model, such as Figure 2 As shown, the pushing assembly includes a support cylinder 9 fixedly connected to the end cover 6. A motor 10 is fixedly connected to the inner side of the top end of the support cylinder 9. A screw 11 is fixedly connected to the end of the main shaft of the motor 10. A threaded cylinder 12 is helically connected to the outer side of the screw 11. The threaded cylinder 12 is fixedly connected to the connecting plate 13, so that the motor 10 drives the screw 11 to rotate helically inside the threaded cylinder 12, and the threaded cylinder 12 drives the connecting plate 13 to reciprocate in the vertical direction.

[0027] As a further improvement to this utility model, such as Figure 3 As shown, the engaging assembly includes a limiting rod 17 that engages with the scraper ring 14. The limiting rod 17 is slidably connected to the connecting plate 13. A push button 15 is fixedly connected to the top of the limiting rod 17, and the push button 15 is slidably connected to the connecting plate 13. This allows the limiting rod 17 to engage with the scraper ring 14, thereby limiting and fixing the scraper ring 14, and also facilitating the disassembly and cleaning of the scraper ring 14 later.

[0028] As a further improvement to this utility model, such as Figure 3As shown, one end of the limiting rod 17 is fixedly connected to a spring 16, and the other end of the spring 16 is fixedly connected to the connecting plate 13. The spring 16 provides a spring force to the limiting rod 17, so that the limiting rod 17 can be stably engaged with the scraper ring 14.

[0029] Workflow: When it is necessary to clean the waste on the surface of the electrode rod 8, the motor 10 drives the screw 11 to rotate spirally inside the threaded cylinder 12, causing the threaded cylinder 12 to move back and forth vertically with the connecting plate 13. At the same time, the connecting plate 13 also moves the scraper ring 14 vertically along the electrode rod 8, so that the scraper ring 14 scrapes off the waste on the surface of the electrode rod 8, preventing the waste from accumulating on the surface of the electrode rod 8. At the same time, no manual cleaning is required, which is convenient for the staff to use. The number of scraper rings 14 is the same as the number of electrode rods 8, ensuring that each electrode rod 8 can be cleaned.
