[0002] For the purification treatment of phosphorus-containing wastewater, it is usually necessary to pass through steps such as grid filtration, sedimentation in a sedimentation tank, PH adjustment, and oxidation, so that the wastewater can achieve the purpose of recycling and reuse after multi-stage purification treatment. When sedimentation is performed, dregs are generated on the surface of the wastewater, and at this time, a dreg scraping mechanism needs to be used to clean the dregs accumulated on the surface of the wastewater to a dreg discharge groove, so as to avoid the influence of the continuous accumulation of the dregs on the purification treatment of the wastewater in the sedimentation tank.

[0003] In the prior art, after the dregs on the surface of the wastewater are cleaned and scraped to the dreg discharge groove by the dreg scraping plate during the purification treatment of the wastewater, the surface of the dreg scraping plate is attached with residual dregs due to the lack of a surface self-cleaning function. When the dreg scraping plate returns to the sedimentation tank again, the dregs will return to the sedimentation tank again and be re-dissolved and dispersed, which not only causes the rebound of the pollutant concentration in the sedimentation tank and reduces the water quality of the effluent, but also the oil droplets or colloidal particles that are not broken in the dregs will interfere with the combination of the flocculant and the pollutants, form a more stable emulsion system, and increase the treatment difficulty.

[0030] An operation method of the wastewater high-efficiency purification device based on phosphorus processing, which is suitable for the wastewater high-efficiency purification device based on phosphorus processing, and includes the following steps: S1: first, the wastewater is delivered to the grid tank 2 for preliminary filtration, so that the suspended solids and large impurities therein are intercepted, and then the wastewater is sequentially delivered to the primary sedimentation tank 3 and the secondary sedimentation tank 4 for sedimentation purification treatment; S2: when the wastewater in the primary sedimentation tank 3 and secondary sedimentation tank 4 purification treatment, start the slagging mechanism, through the slagging mechanism slowly moving to the surface of the wastewater in the sedimentation tank scum clean scraping to the slagging groove; S3: when the slagging mechanism moves to the slagging groove, start the air cylinder 28, through the air cylinder 28 drive fixed frame 29 extension, so that the sponge block 33 and the slagging mechanism, when the slagging mechanism reset, through the sponge block 33 can be on the surface of the slagging mechanism cleaning.

[0031] The working principle is that when the wastewater is purified, first, the wastewater is delivered to the grid pool 2 for preliminary filtration, so that the suspended solids and large impurities are intercepted, then the wastewater is delivered to the primary sedimentation tank 3 and the secondary sedimentation tank 4 in turn for sedimentation purification treatment, when the wastewater is purified in the primary sedimentation tank 3 and the secondary sedimentation tank 4, a large amount of scum will float to the surface of the wastewater, at this time, the scum scraping mechanism is started, the scum on the surface of the wastewater in the sedimentation tank is scraped to the scum discharge groove by the slow movement of the scum scraping mechanism, when the scum scraping mechanism moves to the scum discharge groove, the air cylinder 28 is started, the fixed frame 29 is driven to extend by the air cylinder 28, so that the sponge block 33 on the bottom mounting plate 32 of the fixed frame 29 is attached to the scum scraping mechanism, when the scum scraping mechanism resets, the surface of the scum scraping mechanism can be cleaned by the sponge block 33, so that the scum attached to the surface of the scum scraping mechanism is not carried into the sedimentation tank again, after the wastewater enters the primary sedimentation tank 3 and the secondary sedimentation tank 4, the motor one 6 is started, the screw rod 7 is rotated by the motor one 6, the screw sleeve 8 slides along the screw rod 7 under the limiting action of the limiting piece 10, the connecting piece 9 drives the lifting sleeve 11 to slide, so that the U-shaped plate 14 and the scraper plate 16 slide slowly to the scum discharge groove side, when the scraper plate 16 moves to the partition plate 42, because the top of the partition plate 42 is inclined, and the water surface height of the wastewater is lower than the height of the inclined surface of the partition plate 42, the scraper plate 16 can clean the scum generated in the purification process to the inclined surface of the partition plate 42, and move along the inclined surface of the partition plate 42 until it is pushed into the scum discharge groove, in this process, the scraper plate 16 continuously moves up and compresses the spring one 12 until the scraper plate 16 is separated from the partition plate 42, and then under the elastic force of the spring one 12, the scraper plate 16 quickly slides down and resets, when the scraper plate 16 cleans the scum in the scum discharge groove, the motor one 6 is reversed, the screw rod 7 is reversed, and the screw sleeve 8 drives the scraper plate 16 to return to the sedimentation tank again, in order to prepare for the next scum discharge, when the scraper plate 16 slides to the scum discharge groove side, the guide block 27 is in direct contact with the outer wall of the guide plate 20 and is pressed, and the guide block 27 does not contact with the guide groove, at the same time, the spring three 26 is in a compressed state, until the scraper plate 16 enters the scum discharge groove and separates from the inclined surface of the partition plate 42, the guide block 27 corresponds to the bottom end of the inclined groove 21, at this time, under the elastic force of the spring three 26, the guide block 27 directly slides into the inclined groove 21, at the same time, the sponge block 33 below the fixed frame 29 moves and is attached to the surface of the scraper plate 16 under the action of the air cylinder 28, thereafter, under the reverse action of the motor one 6, the scraper plate 16 starts to move away from the scum discharge groove and resets, the guide block 27 slides along the inclined groove 21, so that the U-shaped plate 14 and the T-shaped plate 13 tilt and slide and compress the spring one 12, in this process, the sponge block 33 will always be attached to the surface of the scraper plate 16, until the guide block 27 slides into the horizontal groove 22, the scraper plate 16 separates from the sponge block 33 and is no longer cleaned, thereafter, the guide block 27 slides along the horizontal groove 22, in this process, the bottom end of the scraper plate 16 is always higher than the surface of the wastewater,When the guide block 27 slides out at the inclined part 23, the guide block 27 compresses the spring three 26 again, and under the elastic force of the compressed spring one 12, the scraper 16 enters the wastewater again, facilitating the cleaning of the scum generated on the surface of the wastewater again. Through this structure, the scraper 16 can not contact the surface of the wastewater when it returns to the reset position, avoiding that the scraper 16 will clean the newly generated scum to the side far away from the residue groove when it returns. Through the setting of the scraper 16 into a vertical plate and an inclined plate, only the inclined plate contacts the scum when it cleans the scum, and because the inclination angle of the inclined plate is the same as the inclination angle of the inclined groove 21, when the guide block 27 slides along the inclined groove 21, the sponge block 33 can ensure the state of being closely attached to the surface of the inclined plate, completing the cleaning of the scum attached to the surface of the inclined plate. When the scraper 16 moves to the residue groove, the cam 36 on the fixing frame 29 approaches the vertical plate under the action of the air cylinder 28. At this time, the motor three 35 is started, the rotating shaft two 41 is driven to rotate through the motor three 35, the cam 36 rotates and continuously presses the vertical plate to separate, when the cam 36 presses the vertical plate, the vertical plate slides along the supporting rod 15 and compresses the spring two 17, when the cam 36 separates from the vertical plate, the vertical plate quickly resets and hits the top plate 18 under the elastic force of the spring two 17. Through the impact of the vertical plate on the top plate 18, vibration is generated, the residual scum attached to the inclined plate is separated from the scraper 16 under the action of the vibration, and the cleaning difficulty of the sponge block 33 is reduced. When the scraper 16 separates from the sponge block 33, the motor two 30 is started, the rotating shaft one 31 is driven to rotate through the motor two 30, the mounting plate 32 rotates, and then the sponge block 33 rotates to the side of the pressing plate one 37. The sponge block 33 will pass through the pressing plate one 37 and the pressing plate two 38 in turn, because the thickness of the pressing plate one 37 is greater than that of the pressing plate two 38, the water absorbed by the sponge block 33 when it cleans the scraper 16 is squeezed out. Then, the motor two 30 is reversed, the sponge block 33 is reversed and reset. When the motor one 6 is forward rotated, the sponge block 33 passes through the pressing plate two 38, because the inclined surface of the protruding part 39 is adapted to the rotating direction of the sponge block 33, the protruding part 39 will not affect the sponge block 33. When the motor two 30 is reversed, the sponge block 33 will pass through the pressing plate two 38 again. At this time, because the rotating direction of the sponge block 33 is opposite to the inclination direction of the protruding part 39, the protruding part 39 will continuously scrape the surface of the sponge block 33, reducing the pollution degree of the sponge block 33. When the scraper 16 moves to the side of the residue groove and slides to the highest point of the inclined surface of the partition plate 42, because the inclined plate of the scraper 16 separates from the partition plate 42 by a part, the inclined plate will be lowered by a part under the action of the spring one 12 until the inclined plate completely separates from the partition plate 42. In this process, the hemispherical protrusions on the mounting strip 19 at the bottom of the inclined plate will continuously contact the highest point of the inclined surface of the partition plate 42, so that the inclined plate is continuously lifted and lowered under the action of the spring one 12. Through the impact of the inclined plate with the highest point of the inclined surface of the partition plate 42 when it is lowered each time, vibration is generated, the scum attached to the inclined plate is shaken off through the vibration.To facilitate the subsequent sponge block 33 cleaning operation.
