Abstract

The invention discloses a flow measuring device for sewage containing solid garbage, and relates to sewage flow measurement. The flow measuring device comprises an ultrasonic wave emitting circuit, an ultrasonic wave emitter, two ultrasonic wave receiving sensors, an ultrasonic wave receiving circuit, an analog-digital conversion circuit and a flow calculation module, wherein the output end of the ultrasonic wave emitting circuit is connected with the input end of the ultrasonic wave emitter; the ultrasonic wave emitter is mounted at the bottom of a sewage discharge pipeline; the two ultrasonic wave receiving sensors are mounted at the top of the sewage discharge pipeline; the input end of the ultrasonic wave receiving circuit is connected with the output ends of the two ultrasonic wave receiving sensors; the ultrasonic wave receiving circuit is used for amplifying, filtering and performing envelope detection treatment on a received ultrasonic wave signal; the output end of the ultrasonic wave receiving circuit is connected with the input end of the analog-digital conversion circuit; the output end of the analog-digital conversion circuit is connected with the input end of the flow calculation module; the flow calculation module is used for acquiring envelop of two received signals, used for subsequently performing relevant calculation so as to acquire the relevant peak positions, and used for calculating the flow velocity and the flow of sewage according to the distance between the two ultrasonic wave receiving sensors.

Description

technical field [0001] The invention relates to sewage flow measurement, in particular to a sewage flow measurement device containing solid waste. Background technique [0002] Waterlogging caused by insufficient urban drainage systems in emergencies such as extreme weather has become a concern in my country. Many new water diversion, drainage pumping station projects and sewage treatment plants have been built in various places for sewage treatment. In the process of sewage discharge, the measurement of various types of sewage with large diameter and large flow is bound to be involved. [0003] With the rapid development of ultrasonic technology, electronic technology, computer and other technologies, ultrasonic flowmeters have been widely used in large-diameter and large-flow liquid flow measurement, and the technology has become more mature and perfect. The good performance-price ratio of ultrasonic flowmeter itself makes its application more and more widely. There are ...
