Description

Technical Field

[0001] The invention relates to the field of sewage treatment, and in particular to a high-efficiency electrolysis device for sewage treatment. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people.

[0003] In sewage treatment, it is a common method to use an electrolysis device to electrolyze metal ions and organic matter in sewage. However, in conventional sewage treatment, sewage is often stored in a flowing sewage pool, resulting in insufficient time for electrolysis of sewage, inability to fully electrolyze organic matter, and different concentrations of organic matter in different underwater areas of sewage. Electrolysis equipment is often used for static treatment, which means that the sewage cannot be fully electrolyzed. Summary of the invention

[0008] Furthermore, the power mechanism also includes a transmission belt 2 mounted on the outer wall of each of the rotating shafts 1, and one end of the transmission belt 2 away from the rotating shaft 1 is mounted on the outer wall of the rotating shaft 2. The outer wall of the output end of the motor is fixedly connected with a plurality of shifting plates.

[0009] Furthermore, a self-cleaning mechanism is provided at the end of one end of the connecting rod away from the motor, and the self-cleaning mechanism includes a scraper fixedly connected to the side wall of each connecting rod, and the side wall of the scraper is fixedly connected with a plurality of soft bristles. The bottom lower wall of each fixed frame is fixedly connected with an outer frame, each outer frame is arranged on the outside of the electrode, and the inner wall of the outer frame is fixedly connected with a plurality of soft bristles.

[0010] Further, a dust filter mechanism is provided below the fixed frame, and the dust filter mechanism includes an eccentric wheel fixedly connected to the lower wall of the bottom of each fixed frame, each of the rotating shafts 1 respectively penetrates the upper wall of the eccentric wheel and extends to the outside, and each of the extending parts of the rotating shafts 1 is respectively fixedly connected to a filter cartridge, and each of the extending parts of the rotating shafts 1 is respectively fixedly connected to the top upper wall of the filter cartridge;

[0011] Wherein, each of the rotating shafts is rotatably connected to the central axis of the eccentric wheel.

[0012] Furthermore, the dust filtering mechanism also includes a top rod respectively arranged on the top side wall of each filter cartridge, each of the top rods respectively penetrates the top side wall of the filter cartridge and extends to the interior, each extension portion of the top rod is respectively fixedly connected to a compression plate, each of the compression plates is respectively slidably connected to the inner wall of the filter cartridge, and each of the upper walls of the compression plates is respectively fixedly connected to a plurality of springs, and one end of each spring away from the compression plate is fixedly connected to the top lower wall of the filter cartridge.

[0015] An electrolysis method of a high-efficiency electrolysis device for sewage treatment comprises the following steps:

[0016] S1: When treating sewage, the sewage is injected into the electrolytic cell through the water inlet, and then the motor is started. After the motor rotates, it drives the secondary gear to rotate. Under the action of the main gear, the secondary gear starts to rotate and drives the rotating shaft 1 to rotate. The rotating shaft 1 drives the two electrodes to rotate through the transmission belt 1. At the same time, the rotating shaft 1 also drives the rotating shaft 2 to rotate through the transmission belt 2;

[0017] S2: When each electrode rotates, its outer surface is cleaned due to contact with the soft bristles. After the motor rotates, the scraper on the side wall of the connecting rod starts to rotate, and the soft bristles on the outer side slide relative to the inner wall of the electrolytic cell to clean the sludge attached to the inner wall of the electrolytic cell;

[0018] S3: After each rotating shaft rotates, it drives the filter cartridge to rotate. When the filter cartridge rotates, the push rod slides on the lower wall of the eccentric wheel and squeezes the compression plate. After the air in the filter cartridge is squeezed by the compression plate, the sewage outside the filter cartridge enters the filter cartridge through the conduit;

[0019] S4: After entering the filter cartridge, the sewage is filtered by the activated carbon when passing through the double-layer filter screen, and then reaches the bottom of the filter cartridge through the sieve holes, and is finally discharged from the filter cartridge by compression of the compression plate. After a certain period of electrolysis, the sewage can be pumped out through the water inlet.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) When the motor rotates, the electrodes of the present invention simultaneously stir the sewage. The large number of electrodes and the wide coverage area can make the impurities in the sewage more evenly distributed, thereby improving the electrolysis efficiency of the electrodes. The electrodes themselves rotate, and the centrifugal force generated during the rotation can reduce the bubbles generated on the electrode surface due to the redox reaction, thereby ensuring that the conductivity of the electrode is not affected.

[0022] (2) When each electrode rotates, its outer surface is cleaned due to contact with the soft bristles. After the motor rotates, the scraper on the side wall of the connecting rod starts to rotate, and the soft bristles on the outside slide relative to the inner wall of the electrolytic cell to clean the sludge attached to the inner wall of the electrolytic cell. The motor is very easy to be corroded and covered during use, which leads to a decrease in the conductivity of the electrode, especially in a sewage environment. By using the soft bristles and the rotation of the electrode, most of the covering can be cleaned, thereby slowing down the corrosion rate of the electrode and extending the service life of the electrode.

[0023] (3) When the rotating shaft of the present invention rotates, it drives the filter cartridge to rotate. When the filter cartridge rotates, the push rod slides on the lower wall of the eccentric wheel and compresses the compression plate. After the air in the filter cartridge is squeezed by the compression plate, the sewage outside the filter cartridge enters the filter cartridge through the conduit. After entering the filter cartridge, the sewage is filtered by the activated carbon when passing through the double-layer filter screen, and then reaches the bottom of the filter cartridge through the sieve hole. The metal ions and some impurities in the sewage have a great influence on the conductivity of the electrode, and may even corrode the electrode, resulting in the electrode being unable to be used for a long time. The activated carbon can absorb the metal ions in the sewage, and the sieve hole can filter out some large particles of impurities. The water treated by the filter cartridge is relatively clean, which can reduce interference factors when the electrode is working, thereby extending the service life.

[0024] (4) In the present invention, after the motor rotates, a number of paddles on the outer wall of the motor output end rotate together. When the paddle rod rotates, the sewage on the outside thereof can be moved. Since there are a large number of mechanisms on the outside of the motor output end, they will generate a vortex when they rotate. Some impurities will gather at the center of the vortex along with the sewage. The paddle plate is located at the center of the vortex. The impact force brought by the rotation of the paddle plate can disperse the impurities gathered at the center to the surrounding areas, thereby ensuring more thorough electrolysis.
