One end of water conveying pipe for linking the water tank is a vertical segment, from which a sampling branch-tube is led out. The drainage pump of water tank is linked to trunk of water pump and has an one-way drainage valve. The solid particles are dropped in water tank under the action of dead weight and impact force, so to attain the aim that smaller suspended substance is retained in water sample.
Description
The present invention relates to a kind of water sampling system, be used for the water sampling in automatic water quality monitoring field.
In the modern society, develop rapidly along with science and technology, people are the problem of concern for the environment and water pollution more and more also, no matter is domestic water or process water, and the testing of water quality has been become important key link in various confessions, the disintegrating system in waste pipe.Be used for chemico-analytic water sample requirement and keep less suspension contained in the water except that anhydrating solid particle.At present, the collection of water sample generally is to draw water with the water pump pressurization, directly takes after water-supply-pipe output, or feeds water tank by water-supply-pipe, makes water sample from the water tank water intaking subsequently.The import and the water-supply-pipe of water pump are respectively equipped with filter screen, and the filter screen of water pump is used for the thicker solid impurity of filtering, and the filter screen of water-supply-pipe is used for the more tiny granule foreign of filtering.Termination of pumping after once sampling finishes, and with the water tank emptying, turn on pump repeats aforesaid operations when sampling once more.The shortcoming of this water sampling system is, though the water sample through twice filtration can be removed most of granule foreign, but because the filter screen of water-supply-pipe is thinner, make in the water less suspension also together by filtering, can not reach the sampling requirement to water sample, the filter screen of the filter screen of water pump and water-supply-pipe is all easily stopped up by impurity in addition, uses repeatedly and must cause current not smooth, thereby need often unpick and wash filter screen, maintenance workload is big.
The purpose of this invention is to provide a kind of new water sampling system, it can overcome the shortcoming of existing water sampling system, can remove the solia particle in the water sample easily, can keep less suspension in the water again, and avoid unpicking and washing filter screen, and keep system's current unimpeded, reduce maintenance workload.
Water sampling system of the present invention comprises water pump and water tank, water pump is provided with filter screen, the bottom of water tank is provided with drainpipe 10, this drainpipe is equipped with draining valve, water pump house steward 2 links to each other with the water inlet of water tank by water-supply-pipe 1, this water-supply-pipe is equipped with water regulating valve, the invention is characterized in, the end that said hydraulic pipeline 1 is connected with water tank is one section vertical pipeline section, guarantee that current direction is dirty and go into water tank, upwards draw a sampling arm 5 from this vertical pipeline section, this sampling arm extracts water sample by aspirating mechanism; Said drainpipe 10 links to each other with the water pump house steward, and draining valve is a retaining valve, contains the check valve that oriented discharge direction is opened, and a side of valve is subjected to the static pressure of water in the water tank, and opposite side is subjected to the dynamic pressure of the water of water pump generation.Under the situation that water pump is opened, dynamic pressure is greater than static pressure, and valve is closed; When water pump quit work, dynamic pressure disappeared, and valve is opened to drainage direction under the effect of water tank static pressure, the water that water tank is discharged is reversely to flow back in the water source by water pump, and meanwhile, the filter screen of water pump is because of being subjected to the flushing of reverse current, online attachment comes off automatically, has guaranteed the unimpeded of filter screen.Among the present invention, the aspirating mechanism of sampling arm can be conventional pumps such as common gear-type pump, peristaltic pump or siphon mechanism etc., also can adopt ejector, this ejector links to each other with water pump house steward 2 by a pipeline 12, and the end and the jet pump intake of sampling arm 5 join.In this scheme, insert the water sample analysis system in the pipeline of sampling arm 5, directly feed the analyzing and testing program that the water sample analysis system is scheduled to by the water sample of sampling arm collection.
Water sampling system of the present invention is upwards drawn water sample in being in the current of the state of flowing downward, utilize the momentum effect from gravity and current of solid particle, a thing is sunk rapidly, and water sample pumping direction and particles settling are anti-phase each other, have quickened the separation of the two.Therefore need not to be provided with filter screen in the water-supply-pipe, guaranteed that pipeline is unimpeded.Because impulsive force is much larger than the suction force of sampling arm, particle can not be sampled arm and draw, and less suspension is then drawn with water sample, thereby the water sample of collection of the present invention more meets the requirement of water sample detection.The present invention utilizes the contrary inflow pump of the draining of water tank, and the scheme of recoil water pump filter screen makes the every start-stop of water pump once, all cleans primary filter screen automatically, has overcome the easy stifled tired brain that brings of filter screen.As seen water sampling system of the present invention is reasonable in design, reliable operation, and maintenance workload is little.
