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, because the water body of rivers, lake and reservoir wetland is subjected to the influence of rainwater or flood tide, 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 sand basin that designs.
Background technology
In the surface water on-line monitoring is used, desilting is handled 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 about 100L, water sample pumps into sand basin by adopting water pump, be that 30min leaves standstill desilting then, by two stage pump supernatant pumped in the sampling overflow device of each analyser again.Be draining at last, tap water cleans sand basin, finishes 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 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, guarantee the normal operation of system and the just necessary frequent artificial cleaning sand basin of reliability of data, consume a large amount of tap water and algicide, cause the significantly increase of the operating cost and the maintenance cost of system.
Summary of the invention
For solving in the prior art surface water on-line monitoring water quality testing data in the processing of water sample desilting is lost pin, operating cost and the high difficult problem of maintenance cost.The invention provides the self-cleaning sand basin that a kind of water sample detection is accurate, processing cost is low, maintenance cost significantly reduces.
At above essential technique problem, the corresponding technical solution scheme of the present invention is:
A kind of self-cleaning sand basin, comprise the sand basin main body, the sand basin main body is provided with and imports the water sample water inlet that detects water sample, discharge the freeing port of water sample, the Overflow drainage mouth, the tap water water inlet of external wash-down water and the thief hatch that is used to gather water sample, it is characterized in that the sand basin main body is cylindrical pvc pipe, the water sample water inlet is positioned at sidewall near bottom position, freeing port is positioned at the bottom of sand basin main body, the external electrical ball valve of water sample water inlet and freeing port, thief hatch is positioned at the above position, middle part of sand basin main body, the Overflow drainage mouth is higher than thief hatch, the tap water water inlet is positioned at sand basin main body top, thief hatch and tap water water inlet all are connected with solenoid valve, the run-down pipe water delivering orifice is equipped with the level switch of the liquid level sensor that detects the sand basin water level and control water level and by making ball valve, be provided with piston type self-cleaning floating drum in the sand basin main body, have the fixing cleaning brush of cylindrical floating drum cylindrical shell and cylindrical shell bottom of circulation water channel in the middle of described piston type self-cleaning floating drum comprises, the caliber of cylindrical floating drum is 0.8～0.9 times of husky tank main body caliber.The present invention adopts cylindrical pvc pipe as the sand basin main body, make sand basin volume-diminished nearly 1/10, the height of water of utilizing cylindrical height to form, in last water process, rising along with water level in the sand basin, silt only rests on lower floor under action of gravity, make the upper strata water sample can obtain clarification fast, improve desilting efficient greatly, shorten the desilting time, dwindled the possibility that water sample changes as far as possible, guaranteed the authenticity of water sample, utilize sand basin thief hatch height, supernatant is imported in each analytical instrument sampling overflow device, do not need two stage pump to promote supernatant; The present invention is at the liquid level sensor of sand basin Overflow drainage mouth installing, whether can detect sand basin is full of, can control the consumption of adopting the water time and cleaning tap water effectively, the operating cost and the maintenance cost of system are reduced greatly, because cylindrical sand basin is built-in with piston type self-cleaning floating drum, utilizes buoyancy of water to drive cleaning brush the sand basin inwall is cleaned.All can clean with the rising of water level or the cleaning brush of decline floating drum bottom inwall at every turn, guarantee that the sand basin inwall keeps clean for a long time, do not have incrustation scale or microorganism and generate, system can steady in a long-term be moved, do not need manual maintenance and cleaning continually, the spending of having saved algicide.
Consider the convenience of processing and manufacturing, the invention provides a kind of easy piston type self-cleaning floating drum, the mozzle of the cylindrical shell that cylindrical floating drum is made by PVC, upper-lower seal cover plate and middle part conducting is welded, cleaning brush is a silicone rubber plate, and silicone rubber plate is fixed on cylindrical floating drum cylindrical shell bottom by sheet rubber installing plate, pressing plate.
The rectangular parallelepiped sand basin of the stainless steel welding of generally adopting compared to existing technology, the present invention has following technique effect;
(1). the present invention adopts cylindrical sand basin, utilize sand basin and natural gravity height silt, but the silt rapid subsidence is in lower floor in the water level uphill process, and desilting efficient and speed significantly improve;
(2). the present invention has significantly dwindled the volume of sand basin, saves the consumption of cleaning tap water greatly, utilizes drop that supernatant is directly imported in the analytical sampling overflow device, does not need two stage pump to promote supernatant to analytical instrument;
(3). sand basin main body of the present invention adopts standard PVC tubing to make, and the self-cleaning floating drum adopts pipe fitting and board making, and cost significantly reduces, and also is convenient to more install, and the more used stainless steel sand basin of cost has bigger reduction, installs also convenient.
