Abstract
A non-blocking and non-filtering liquid sampling device comprises a sampling pump, a liquid storage tank, a micro-tube pump and a connecting pipeline, and is characterized in that a back flushing tank and a one-way valve are arranged between the liquid storage tank and the sampling pump, the inlet and the outlet of the one-way valve are respectively communicated with the bottom of the back flushing tank and the water outlet of the sampling pump, the water outlet of the back flushing tank is obviously higher than the suction inlet of the sampling pump, and the suction inlet of the micro-tube pump is connected with the liquid storage tank and faces to the flowing direction of liquid in the liquid storage tank. The utility model is used for water environment on-line monitoring or other liquid sampling monitoring, liquid need not filter, and the microtube pump can not block up, and debris such as pasture and water in time are clear away to the sample pump sunction inlet under the effect of backwash water, need not artifical clearance, and sample good reliability, the running cost is low.
Description
Technical field
The utility model relates to a kind of fluid sampling device, especially for the water quality sampling device in the water environment on-line monitoring system.
Background technology
Strengthening monitoring water environment is to carry out environmental protection, maintaining ecological balance, and the importance of the enforcement strategy of sustainable development, and how the timely water sample that extracts the monitoring point easily is the primary link that carries out monitoring water environment.At present, sampling pump is adopted in the water quality sampling, and its suction inlet stretches in the water, draws up the water that comes and flows into water storing tank, is pumped into analytical instrument by microcapillary again.The sampling pump suction inlet is provided with guard, sucks to stop foreign material such as pasture and water, leaf.But after a while, foreign material are often attached on the guard, cause the sampling pump suction inlet to stop up, and have to be pulled the plug by the people and remove, very trouble.In addition, when water storing tank is taken a sample,, need filter and regular cleaning is safeguarded, influence the reliability of sampler, increase operating cost also often because of the larger particles impurity in the water stops up the microcapillary Pump Suction Nozzle.
Summary of the invention
The purpose of this utility model is to overcome weak point of the prior art, provide a kind of microcapillary Pump Suction Nozzle not need to filter, microcapillary Pump Suction Nozzle and sampling pump suction inlet are avoided stopping up, and can improve reliability, and that reduces operating cost exempts to filter, exempt to stop up fluid sampling device.
The technical solution of the utility model is: exempt to filter, exempt to stop up fluid sampling device and comprise sampling pump, receiver, microcapillary pump and connecting tube, improvements are to set up back flushing tank and retaining valve between receiver and sampling pump, the import and export of retaining valve is connected with back flushing tank bottom, sampling pump water delivering orifice respectively, described microcapillary pump intake links to each other with receiver, and the direction of suction inlet liquid flow in receiver.
The water delivering orifice of above-mentioned back flushing tank is apparently higher than the sampling pump intake, and the angle in microcapillary Pump Suction Nozzle center line and the receiver between the liquid flow path direction is 0 °～45 °.
During the work of this device, extract water sample by sampling pump from tested point, be sent to receiver through variable valve, flow into back flushing tank again, the microcapillary pump that links to each other with receiver is delivered to analytical instrument with water sample.Because the consistent or basically identical of liquid flow path direction in microcapillary pump intake direction and the receiver, larger particles will be pulled away along with washing away of liquid stream in the liquid, can not stop up the microcapillary Pump Suction Nozzle, thereby not need filtration.Exempt to filter and to collect tiny solid particle, thereby guarantee the timeliness and the reliability of sample.When sampling pump quits work, its water delivering orifice pressure reduces, one-way valve opens, the water of back flushing tank flows out from sampling pump, make sampling pump finish the action of " inhale---tell ", to being adsorbed on the removing that recoils of fibrous foreign material on the sampling pump suction inlet guard, not needing the labor cleaning and avoid sampling pump to stop up.This device reliability is good, and operating cost is low.
Description of drawings
Accompanying drawing is that the utility model constitutes and the connection relation synoptic diagram.
Embodiment
As figure, sampling pump 5 extracts water sample and is sent to receiver 1 through variable valve 3, flows into back flushing tank 7 again.Angle in the suction inlet center line of microcapillary pump 2 and the receiver between the liquid flow path direction is α=15 °.The microcapillary pump is delivered to analytical instrument 4 with water sample.The import and export of retaining valve 6 is connected with the water delivering orifice of back flushing tank bottom and sampling pump respectively.The back flushing tank top is provided with spout hole 8.
Claims (3)
1, a kind ofly exempts to stop up, exempt from the filter liquide sampler, comprise sampling pump, receiver, microcapillary pump and connecting tube, it is characterized in that between receiver and sampling pump, setting up back flushing tank and retaining valve, the import and export of retaining valve is connected with back flushing tank bottom, sampling pump water delivering orifice respectively, described microcapillary pump intake links to each other with receiver, and the direction of suction inlet liquid flow in receiver.
2, stop up, exempt from the filter liquide sampler by described the exempting from of claim 1, the water delivering orifice that it is characterized in that back flushing tank is apparently higher than the sampling pump intake.
3, stop up, exempt from the filter liquide sampler by described the exempting from of claim 1, it is characterized in that the angle between the liquid flow path direction is 0 °～45 ° in described microcapillary Pump Suction Nozzle center line and the receiver.
