10. The use method of the flocculation stirring mud scraping system of the high-density sedimentation tank is characterized by comprising the following steps:
s1: the sludge thickness in the sedimentation tank (100) is detected according to the arranged sludge thickness measuring component (400), during detection, the roller shaft (403) can be kept to be abutted against the sludge in the sedimentation tank (100) through the arranged elastic component (404), when the sludge in the sedimentation tank (100) is thick and the driving motor 102 is not enough to provide corresponding torque, through the arrangement of the first connecting rod (402), when the sludge at the bottom of the sedimentation tank (100) is thick, the roller shaft (403) can drive the first connecting rod (402) to move upwards, and is in key connection with the central vertical shaft (103) through the second connecting turntable (405), so that the second connecting turntable (405) connected with the top of the second connecting rod (407) is driven to move upwards along the central vertical shaft (103), so as to drive the second connecting rod (407) to move upwards, and further drive the first switch contact (408) connected with the top of the second connecting rod (407) to be in contact with the second switch contact (502), thereby driving the driving electric cylinder (301) to retract;
s2: when the driving electric cylinder (301) retracts, the first connecting turntable (305) is driven to move upwards along the central vertical shaft (103) so as to drive the cable (303) connected with the first connecting turntable to move upwards, when one end of the cable (303) moves upwards, the connecting block (302) is driven to move through the arranged guide wheel (304), the scraper (204) connected with the first connecting turntable is driven to rotate along the rotating shaft (203), so that the angle between the scraper (204) and the supporting frame (201) is changed, the included angle between the scraper (204) and the supporting frame (201) is increased at the moment, the resistance of the scraper (204) during mud scraping is correspondingly reduced, and therefore, the situation that the mud is accumulated in the sedimentation tank (100) to cause insufficient mud drainage of the sedimentation tank (100) and excessive mud accumulation at the bottom of the tank to cause the load of the mud scraping component (200) to expand, and the driving motor (102) cannot drive the mud scraping component (200), therefore, the driving motor (102) is subjected to power jumping due to the effect of overtemperature maintenance or torque protection equipment, the scraper (204) still continues to scrape mud at the moment, and the sludge at the bottom of the pond can be well cut and dispersed, so that the scraper (204) can conveniently and quickly scrape the sludge, but the sludge at the bottom of the sedimentation pond (100) is difficult to be completely scraped, but partial scraping can be quickly carried out at the moment so that the depth of the sludge in the pond is effectively reduced, and the condition that the driving motor (102) is subjected to power jumping due to the effect of overtemperature maintenance or torque protection equipment can be avoided;
s3: when the sludge in the sedimentation tank (100) is scraped to a normal depth deeply, under the action of the elastic force of the elastic piece (404), the second connecting rod (407) drives the first switch contact (408) to move downwards and contact with the third switch contact (503), at the moment, the driving electric cylinder (301) is driven to extend out, the first connecting turntable (305) and the cable (303) connected to the bottom of the first connecting turntable are driven to move downwards, and the scraping plates (204) continue to scrape the sludge, so that under the condition of resistance of the scraping plates (204), the angle of the scraping plates (204) changes again, the included angle between the scraping plates and the support frame (201) is reduced, at the moment, the scraping plates (204) adjacent to each other are in an interference staggered state relatively, and at the moment, the sludge at the bottom of the sedimentation tank (100) is conveniently and comprehensively scraped.
