Embodiment 1

[0026] In this example, see Figure 1~3 , an automatic filtration and backwashing device for seawater samples, mainly including two parts: an automatic seawater filtration system and a pipeline backwashing system, which are respectively controlled by the main control system, as follows:

[0027] The automatic seawater filtration system mainly includes a water collection device 2, a diaphragm pump 4, a graded filtration device composed of different filter elements with a porosity range of 0.45-100 μ in series, a nutrient salt detector 15, a waste liquid pool 19 and a series of solenoid valves. The water outlet of the water collection device 2 is communicated with the suction port of the diaphragm pump 4, and the sea water sample can be sucked and transported by the water collection device 2 by the diaphragm pump 4, at least between the water outlet of the diaphragm pump 4 and the waste liquid pool 19 The water sample filtration and detection pipeline is set up, and the water sa...

Embodiment 2

[0045] This embodiment is basically the same as Embodiment 1, especially in that:

[0046] In this example, if Figure 4 As shown, in the automatic seawater filtration system, there is also an auxiliary diaphragm pump connected with the signal of the main control system. The auxiliary diaphragm pump is used as the second water pump, and its pipeline connection mode is exactly the same as that of the diaphragm pump 4, so that The water outlet of the water sampling device 2 communicates with the suction port of the auxiliary diaphragm pump, and the auxiliary diaphragm pump can also absorb and transport seawater samples through the water sampling device 2 . Two water pumps are installed in the water distribution pipeline in this implementation. When the water supply of the first water pump is insufficient, the second water pump is turned on, which provides guarantee for the stable operation of each detection system of water samples, forms an effective redundancy mechanism, and pr...

Embodiment 3

[0048] This embodiment is basically the same as the previous embodiment, and the special features are:

[0049]In this embodiment, in the pipeline backwashing system, the nutrient salt detection pipeline composed of the second solenoid valve 14, the nutrient salt detector 15 and the third solenoid valve 16 in series can also be cleaned, that is, by controlling the corresponding The solenoid valve of the ozone generator 1 is used to flush the nutrient analyzer 24 with the cleansing water provided by the outlet pipe of the ozone generator 1, and to wash away the attachments on the inner wall of the nutrient salt detection pipeline and the inner wall of the water passage chamber of the nutrient salt detector 15. To waste liquid pool 19. When cleaning the nutrient salt detection pipeline, open the ozone generator 1, the solenoid valve 3 of the washing water main pipe, the sixth solenoid valve 12, the second solenoid valve 14 and the third solenoid valve 16, and the water flow dire...

Abstract

The invention discloses an automatic seawater sample filtration and back-purge device which mainly comprises two parts, namely an automatic seawater filtration system and a pipeline back-purge system, wherein the automatic seawater filtration system and the pipeline back-purge system are controlled by a master control system respectively. The automatic seawater filtration system mainly comprises a water sampling device, a membrane pump, a graded filtration device, a nutritive salt detector, a waste liquid tank, an ozone generator and a series of electromagnetic valves.The device can perform on-line water sample analysis on a water sample conveyed to the nutritive salt detector; analysis datais fed back to a ground control console by a master controller; automatic filtration, detection and analysis of the seawater sample can be achieved; distribution pipelines and detection instruments can be subjected to back surge after filtration; the device is simple in structure and simple to operate; a testing and analysis result is accurate and reliable; operating risks of marine water quality sampling workers can be reduced; the working strength of the workers can be reduced; and the device has an important application value for gradually raising an automatic monitoring level of a sea area around a sea island.

Description

technical field [0001] The invention relates to a surface water quality detection device, in particular to a marine water sample automatic detection device, which is applied in the technical field of marine environment monitoring equipment. Background technique [0002] Marine environment monitoring is an important part of the development of marine strategy. The country's current marine monitoring tasks are carried out by my country's marine management agencies, aiming at monitoring and maintaining the safety of my country's marine environment. Due to the harsh conditions of working at sea, large ships are currently equipped with professional monitoring equipment to go to sea to perform operational tasks. The cost of a single trip is high, and the corresponding supporting resources and facilities required are as high as hundreds of thousands. Even so, the detection task still requires a large number of professionals to classify and process the collected water samples. Due t...
