Fault monitoring and early warning system of mud scraping machine in sedimentation tank and calculation method of system

Abstract

The invention provides a fault monitoring and early warning system of a mud scraping machine in a sedimentation tank. The system adopts two laser distance measuring instruments as measurement equipment of the monitoring system, and the system also comprises a datum acquisition unit, a datum analysis unit and an early warning alarm unit; the two laser distance measuring instruments are installed onthe upper parts of the left and right ends of the sewage sedimentation tank, and the datum acquisition unit, the datum analysis unit and the early warning alarm unit are application software installed in an embedded system. The performance calculation method of the fault monitoring and early warning system of the mud scraping machine in the sedimentation tank adopts the datum analysis unit of a performance monitoring system of mud scraping plates to calculate height change of the mud scraping plates and wear-resistant boot-like fittings and spacing between two adjacent mud scraping plates. The system provided by the invention performs real-time height and position monitoring on the wear-resistant boot-like fittings on two sides and the upper part of each mud scraping plate, when height data, position data and the like exceed preset values of the system, the system automatically generates an alarm information to give a prompt to management workers, and the management workers can replace damaged mud scraping plates and wear-resistant boot-like fittings in time to ensure normal operation of the whole equipment.

Description

technical field [0001] The invention relates to the field of a monitoring, early warning and alarm system and a performance calculation method used in the sewage treatment process, in particular to a fault monitoring and early warning system and a calculation method of a mud scraper in a sedimentation tank. Background technique [0002] When the mud scraper used in the sedimentation tank is working, its supporting driving device (usually sprocket and chain drive) drives the mud scraper of the mud scraper and the wear-resistant boots at the lower end of the mud scraper to rotate, and the raw water entering the sedimentation tank is settled After the pool settles, the supernatant is discharged from the overflow weir plate of the sewage sedimentation tank, and the sludge settled at the bottom of the pool is slowly flowed along the bottom of the pool to the sewage sedimentation under the push of the mud scraper and the wear-resistant boots at the lower end of the mud scraper.

Problems solved by technology

[0004] In order to overcome the disadvantages of the mud scraper used in the existing sewage sedimentation tank due to the absence of an effective monitoring device and application method, the present invention provides a method that adopts two laser rangefinders installed at the left and right ends of the sewage sedimentation tank respectively. In the upper part, the real-time height and position monitoring of the wear-resistant shoes on both sides of the multi-row mud scraper and the upper part driven by the driving device of the mud scraper is carried out. The laser rangefinder has mature technology, high precision, fast response, and non-contact measurement , no wear, easy maintenance, and the height and position data of each passing mud scraper and wear-resistant boots are transmitted to the background through wireless or wired methods. After the background application software performs calculation and analysis, the height data of the mud scraper When the location data, etc. exceed the system preset value, the system will automatically generate an alarm message, thus giving the management personnel a reminder that the mud scraper is faulty or the wear-resistant boots are too worn, and then the management personnel can promptly repair the damaged mud scraper, The wear-resistant boots are replaced to ensure the normal operation of the overall equipment and prevent the fault from expanding. The fault monitoring and early warning system and calculation method of the sedimentation tank mud scraper
