Abstract:?
The utility model relates to an automatic pretreatment device for water samples, which is characterized by comprising a small grit chamber body, a grit chamber sprayer, a water sample cup sprayer, a filter element, a plunger pump, a pneumatic three-way valve, a lubricator, an air filter, a pressure gauge, a water sample cup and a water sample homogenizer. The utility model has the advantages that the volume is reduced to less than one tenth of the original equipment, it can be integrated in a cabinet, and even a pretreatment board can be hung behind the instrument, so the layout is quite compact. The piston pump only needs to use the system air source, so the energy consumption is very low; Because the grit chamber adopts high-pressure gas back-blowing spray, the cleaning effect is remarkable and there is no blockage in continuous operation; Can run continuously for 4-6 months without maintenance; It has complete functions and can realize automatic emptying and automatic cleaning. ?
Sovereignty:
1. An automatic pretreatment device for water samples, which is characterized by comprising:
The small grit chamber main body (1) is provided with a grit chamber ejector (2) at the upper end side of the small grit chamber main body (1).
And is connected with a spray valve (20) of a grit chamber installed on a second installation plate (26) through a pipeline to grit.
The pool spray valve (20) is connected with the sample cup spray valve (2 1) through a pipeline, and is connected with pressurized tap water (28).
The inlet is connected, and the spray valve (2 1) of the sample cup is connected with the sample mounted on the third mounting plate (27) through a pipeline.
Connect the water cup nozzle (17) at the upper end of the water cup body (15), and connect the liquid level switch (3) and the sedimentation tank.
The liquid level switch (4) below the sand basin is arranged at one side of the small sand basin body (1), and the sand basin discharge valve (5) is arranged at
The low end of that small grit chamber body (1) is provide with a filter element (9) on the other side of the upper end of the small grit chamber body (1),
The filter element (9) is connected with the compressed air inlet (29) through the pipeline and the back blowing valve (22) of the grit chamber; the same
When in use, the pneumatic three-way valve (6) and the upright post mounted on the second mounting plate (26) are respectively connected with the pneumatic three-way valve (6) through the pipeline and the tee joint.
The lower end of the plug pump (10) is connected with the water sample nozzle (14) at the lower end of the water sample cup (15), and a pneumatic three-way valve is used.
(6) The through hole at the lower end is connected with the second electromagnetic valve (8), the pipeline, the third electromagnetic valve (1 1) and the plunger pump.
The upper end of (10) is connected with an air filter and a pressure gauge (23) through an oiler (24).
The upper end of the pneumatic three-way valve (6) passes through the first electromagnetic valve (7), the second electromagnetic valve (8) and the third electromagnetic valve.
The solenoid valve (1 1) is connected through a pipeline, and the middle end of the plunger pump (10) passes through the slow release valve (13) and the fourth one.
The solenoid valve (12) is connected to the pipeline between the second solenoid valve (8) and the third solenoid valve (1 1); water sample
The cup (15) is internally equipped with a water sample homogenizer (18), and the top is equipped with a water sample cup level switch (16).
The sample cup discharge valve (19) installed at the upper end of the water cup (15) and the lower end of the sample cup (15) passes through three channels.
Connect to the discharge pipe.
