Problems solved by technology

[0003] At present, the online monitoring of water quality is usually directly connected to the monitoring instrument from the water source, and the water pressure of the water source is generally difficult to control, and the water quality is very poor (especially containing some hard debris), which will cause great damage to the instrument and its pipeline. At the same time, some complex water quality pre-treatment devices will bring extremely high cost and resource consumption in application, and they have no self-cleaning effect, requiring frequent cleaning by personnel

Embodiment

[0024] An automatic flushing, overflowing, and filtering device provided in this embodiment is characterized by a box (11) structure, and the box is divided into an automatic flushing area by an overflow partition (1) and a filter plate (5) (2), the automatic overflow area (6) and the automatic filter area (7), and the water flowing into the automatic flushing area (2) through the water inlet (3) is distributed to the automatic overflow area (6) and the automatic filter area at the same time (7);

[0025] Further, the automatic flushing area (2) is directly connected to the adjustable turning elbow (4) at the end of the water inlet (3), so that the pressurized water flow can wash up the sediment in the automatic flushing area (2) and Suspension, so as to realize the effect of automatic cleaning of sediment;

[0026] Further, an overflow partition (1) with a specific top height is set between the automatic overflow area (6) and the automatic flushing area (2); when the water p...

Abstract

The invention discloses an automatic flushing, overflowing and filtering device. The automatic flushing, overflow and filtering device is of a box structure and internally comprises an automatic flushing area, an automatic overflow area, an automatic filtering area and the like, wherein the automatic flushing area is provided with an elbow directly connected with a water inlet and capable of being adjusted to turn so as to directly flush sediments in a water inlet area by pressurized inlet water, the automatic overflow area is adjacent to the water inlet area, the automatic overflow area and the water inlet area are separated by a height-adjustable overflow plate, the height of the overflow plate is adjusted according to the water inlet amount so as to discharge sediments flushed by the water inlet area along with overflow water, the automatic filtering area is also adjacent to the water inlet area, the automatic filtering area and the water inlet area are separated by a replaceable-mesh filter screen, and the mesh number of the filter screen is reasonably selected according to the national standard of environmental protection, so that water flowing into the filtering area from the water inlet area is filtered. The device of the invention is applied to a pretreatment end of an on-line water quality monitoring instrument, and can well realize automatic cleaning and overflowing of the device and filtration of monitoring water.

Description

technical field [0001] The invention relates to a pretreatment for on-line water quality monitoring, in particular to an automatic flushing, overflow and filtering device for on-line water quality monitoring, belonging to the technical field of on-line instrument monitoring. Background technique [0002] With the rapid development of economy and society, people pay more and more attention to the field of environmental protection; and the online monitoring of water quality has attracted more and more attention because of its advantages of timeliness, accuracy and automation. In the online monitoring of water quality, it is generally necessary to carry out pretreatment on the influent water sample, including decompression overflow and preliminary filtration, etc., to prevent excessive water pressure and hard debris from damaging the instrument and its meter pipeline. [0003] At present, the online monitoring of water quality is usually directly connected to the monitoring ins...
