Abstract
A self-cleaning sand basin belongs to the technical field of environment detection. The self-cleaning sand basin comprises a sand basin main body provided with a water sample water inlet, a water outlet, an overflowing water outlet, a running water inlet and a sampling opening; the sand basin main body is a cylindrical PVC tube; a piston self-cleaning float bowl is arranged in the sand basin main body and comprises a cylindrical float bowl body with a circulating water channel in the middle and a cleaning brush fixed at the bottom end of the bowl body; and the pipe diameter of the cylindrical float bowl is 0.8-0.9 times of that of the sand basin main body. The piston float bowl is utilized, thereby solving the self-cleaning difficult problem of scales on the inner wall of the sand basin; the cylindrical sand basin utilizes the natural gravity of the sand basin and the height sediment, and the sediment can be quickly settled to the lower layer in the process of water level rise, thereby greatly improving the sand-setting efficiency and speed, reducing the volume of the sand basin, and saving the consumption of the washing running water. The parts are manufactured by using standard PVC tubular products; therefore, the cost is greatly reduced and the installation is convenient.
Description
Technical field
The invention belongs to environmental protection monitoring water quality on line preconditioning technique field, be particularly related to the surface water on-line monitoring, be subjected to the impact of rainwater or flood tide due to the water body of rivers, lake and reservoir wetland, often be rich in silt, remove the silt of water body when the present invention is used for monitoring water quality on line and the self-cleaning desilting basin that designs.
Background technology
In the surface water on-line monitoring is used, desilting is processed the pre-service link that is absolutely necessary, what generally adopt at present is the rectangular parallelepiped sand basin that welds with stainless steel, volume is generally in the 100L left and right, water sample pumps into sand basin by adopting water pump, then be the standing desilting of 30min, then by two stage pump, supernatant pumped in the sampling overflow device of each analyser.Be draining at last, tap water cleans sand basin, completes and once adopts the water process.The sand basin of this structure is easy to form incrustation scale because automatic cleaning can't reach good effect on pool wall, produce the microorganisms such as bacterium, algae, and the generation of these microorganisms can have a strong impact on the authenticity of water quality measurement data.Therefore, the reliability that guarantee the normal operation of system and data is manual cleaning sand basin frequently just, consumes a large amount of tap water and algicide, causes the significantly increase of operating cost and the maintenance cost of system.
