Working principle: it is to be noted that the inside of the water inlet end of the water treatment shell 1 is simultaneously provided with a flocculation area, an air floatation area and a scum separation area, the areas are separated by a partition board, wherein a micro-nano bubble generator is installed in the air floatation group and is mainly used for generating micro bubbles, the above is the prior art, the technical scheme is not repeated in excess, when in use, sewage to be treated is firstly put into the flocculation area of the water treatment shell 1 for flocculation reaction, the sewage after the reaction enters the air floatation area, at the moment, the micro bubbles in the air floatation area are attached to flocculates, so that the flocculates and the bubbles rise to the surface of a liquid level together and enter the scum separation area, the driving component 3 comprises a pair of chains, a chain wheel is installed in the pair of chains, a driving shaft is installed in the chain wheel, the driving shaft is connected with the output end of the motor, which is not described in more detail in the technical scheme, when flocs and bubbles enter the scum separation area, the motor is started to drive the driving shaft to rotate and further drive the chain to rotate, the chain simultaneously drives the mounting frame 4 to move in the rotating process, the mounting frame 4 moves to drive the scraping plate 5 to move so as to scrape scum, when the scraping plate 5 moves to the upper part of the separation plate 2, the scum is pushed into the scum collection area between the water treatment shell 1 and the separation plate 2, thereby achieving the effect of scum and water separation, and the scraping plate 5 slides in the direction of sewage under gravity after being overturned along with the movement of the chain by arranging the mounting frame 4 and the scraping plate 5, thereby enabling the scraping plate 5 to move downwards for a certain stroke, thereby prevent that the liquid level in the water treatment shell 1 from appearing changing and leading to scraping board 5 unable to carry out effectual striking off, and set up a plurality of mounting grooves 6 through scraping board 5 inside, can effectually increase the buoyancy of scraping board 5, and then the clean effect of dross at every turn when can guaranteeing that the liquid level is normal is unanimous, simultaneously through setting up the dead weight that mounting groove 6 can effectually reduce scraping board 5, and then reduce the burden of mounting bracket 4 and scraping board 5 to the chain, improve the stability and the life of equipment, simultaneously through setting up mounting bracket 4 and scraping board 5 sliding connection can avoid setting up too high scraping board 5 in order to adapt to different liquid level surfaces, further reduced the burden to the chain;
during the movement of the scraping plate 5, when the scum is scraped, the balance weight ball 801 pushes the supporting rod 802 to compress the reset spring 803 under the action of gravity so as to enable the reset spring 803 to deform and then shrink, in the process, the supporting rod 802 drives the steering pushing block 804 to move at the same time, the contact surface of the steering pushing block 804 and the extrusion block 805 is an inclined surface, the movement direction can be changed, the steering pushing block 804 can push the extrusion block 805 to move towards the inner wall of the water treatment shell 1 at the moment, the wall scraping plate 7 is pushed to be attached to the inner wall of the water treatment shell 1, the scraping effect on the scum on the inner wall of the water treatment shell 1 is effectively improved, the sewage treatment effect is further improved, when the scraping plate 5 rotates above the water treatment shell 1 along with a chain, the position of the scraping plate 5 can be reversed, the balance weight magnetic ball 9 can drop inside the scraping plate 5 so as to generate vibration, the scum on the surface of the scraping plate 5 can be further improved, meanwhile, the balance weight magnetic ball 9 and the ball 801 is separated from the ball, and the reset spring 803 can not influence the scraping plate 7 inside the water treatment shell, and the scraping effect on the scum can not be reduced;
through the design of the rubber scraper 10, an obtuse angle is formed between the scraper 5 and the rubber scraper 10, and the direction of the obtuse angle is consistent with the movement direction of the scraper 5, so that the cleaning effect on scum can be effectively improved, meanwhile, as the rubber scraper 10 has a certain deformability, after being contacted with the partition plate 2, the rubber scraper 10 can deform and then be attached to the partition plate 2, thus scum leakage can not be caused, and the rubber scraper 10 can push scum into a scum collecting area between the water treatment shell 1 and the partition plate 2 in the subsequent movement process, and the scum separating effect is further improved;
in the process of moving the counterweight ball 801, the counterweight ball 9 is driven to move simultaneously, when the scum is separated, the counterweight ball 9 moves downwards at the moment, so that the following magnet 12 can compress the buffer spring 13 under the action of magnetic force to deform the buffer spring 13, and then the elastic rod 14 and the cleaning block 15 are driven to move in the direction away from the rubber scraper 10, so that the scum separation cannot be influenced, when the scraping plate 5 turns over after the scum is separated, the counterweight ball 801 falls inside the scraping plate 5 under the action of gravity, so that the distance between the counterweight ball 9 and the following magnet 12 is increased, the magnetic force applied by the counterweight ball 9 to the following magnet 12 is reduced, and the magnetic force applied by the counterweight ball 9 to the following magnet 12 is smaller than the elastic potential energy of the buffer spring 13 at the moment, so that the buffer spring 13 can reset and push the elastic rod 14 and the cleaning block 15 to move, and the cleaning block 15 can move along the direction of the rubber scraper 10, so that the elastic rod 14 can be pulled to bend and deform, and the cleaning block 15 can scrape the surface of the rubber scraper 10, so that the residual scum is scraped by the surface of the rubber scraper 10, and the rust and the scum on the surface of the rubber scraper 10 can be prevented from being corroded by the equipment is prolonged; in the initial state, the compression spring 16 is compressed by applying pressure, so that the compression spring 16 can continuously apply elastic force to the attaching plate 17 to enable the attaching plate 17 and the rubber scraper 10 to keep an attaching state, and further the cleaning effect of residual scum on the surface of the rubber scraper 10 is ensured; in the deformation movement process of the elastic rod 14, the elastic ring 20 outside the elastic rod is deformed, and the scum can be effectively shielded by the elastic ring 20 so as to prevent a large amount of scum from entering the protective shell 11 to cause influence; in the process of the movement of the follow-up magnet 12, the follow-up magnet also pushes the striking ball 18 to squeeze the limiting elastic sheet 19 to deform, and after the follow-up magnet 12 resets, the limiting elastic sheet 19 drives the striking ball 18 to reset to strike the inner wall of the protective shell 11 to generate vibration, so that external scum is shaken off, and the scum cleaning effect is improved;
after the scum is discharged into the scum collecting area between the water treatment shell 1 and the partition plate 2, a large amount of micro bubbles in the scum are not easy to burst, so that the scum in the scum collecting area is gradually increased, and further the situation that the scum overflows excessively occurs; the titanium alloy material of the impact block 23 can prolong the service life of equipment and has good anti-corrosion effect; in the process of moving the magnetic impact ball 22, the inertial ball 25 in the liquid storage bag 24 can pull the connecting rope reciprocally under the action of the inertial force, and the inertial force generated by the inertial ball 25 should be enough to pull the liquid storage bag 24 to deform at this moment, so that the pressure in the liquid storage bag 24 is increased after deformation, and then the defoaming liquid stored in the liquid storage bag is sprayed into the scum collecting area through the liquid discharge pipe, so that the capacity of the scum collecting area is further improved, and the defoaming liquid can be a defoaming agent, water or other solvents capable of eliminating bubbles.
