Abstract

The utility model discloses a water quality monitoring and sampling device which comprises a water extracting device, a main pipeline communicated with the water extracting device, a branch pipeline communicated with the main pipeline, and a water taking device connected with the branch pipeline, wherein a return pipeline is communicated between the branch pipeline and the main pipeline; the return pipeline comprises a water inlet pipeline and a water return pipeline; and the two ends of the water inlet pipeline and the water return pipeline are respectively communicated with the main pipeline and the branch pipeline. The water quality monitoring and sampling device leads a filter screen to be used for a long time and not to be blocked, and ensures the impact of water flow for the filter screen and a sampler to be smaller, thus being beneficial to prolonging the replacement and service life of the filter screen and ensuring the sampled water to have better instantaneity and representativeness.

Description

The water quality monitoring sampler
Technical field
The utility model relates to environmental protection tests equipment, relates in particular to a kind of water quality monitoring sampler.
Background technology
When water quality is carried out on-line monitoring, at first need detected water sample is collected in the on-line monitoring system, the water sampling device generally comprises submersible pump, trunk line, sampling pump and branch pipe(tube) etc.For impurity blocking pipe in the anti-sealing, the following dual mode of general employing solves: first kind, detected water sample is extracted in a header tank or the pond, and carry out post precipitation sampling Detection again; Second kind is to install screen pack additional before branch pipe(tube), the impurity in the filtering water.But in use, all there is weak point in above dual mode: first kind of mode, adopt special water box or pond, and promptly increased volume, be not easy to again clean, the water sample of getting simultaneously is not representative, can not truly reflect instantaneous water quality; The second way, as the filter screen of selecting for use is improper, causes sampling line to stop up or the filter screen latch up phenomenon easily.Application number a kind of sampler that has been 01262694.5 patent disclosure, the current suction direction of the branch pipe(tube) of this sampler is opposite with the water (flow) direction of trunk line, and install screen pack additional in sampler the place ahead, effectively like this avoided bigger solid particle to be inhaled into branch pipe(tube), but also there is defective in this sampler, be exactly because the branch pipe(tube) water (flow) direction is opposite with the trunk line water (flow) direction, therefore, water sample suction manifold road is just needed bigger power, not only bring burden to sampling pump, also, big to the impact of filter screen and sampler because current suction is big, damage easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of water quality monitoring sampler, a kind of be not easy blocked, and the sampling more representative water quality detection sampler.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The water quality monitoring sampler comprises picotan, the trunk line that is communicated with picotan, and the branch pipe(tube) that is communicated with trunk line, the water fetching device that is connected with branch pipe(tube) is communicated with return line between described branch pipe(tube) and the described trunk line.
Described return line comprises inlet pipeline and water return pipeline, and described inlet pipeline and water return pipeline two ends are communicated with described trunk line and branch pipe(tube) respectively.
Described water fetching device comprises the sampling pump that is communicated with described branch pipe(tube), the pipe sampler that is communicated with described sampling pump.
Be provided with filter screen before the pipe sampler on described branch pipe(tube).
The connected mode of described pipe sampler and branch pipe(tube) is for flexibly connecting.
The angle of described water return pipeline and trunk line is an acute angle.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
1, branch pipe(tube) of the present utility model is connected by a return line with trunk line, enter the inlet pipeline of return line by deadweight and current inertia from the water elder generation that trunk line flows through, with the intersection of water return pipeline, the impurity that particle and weight are bigger in the water flows back to trunk line by the effect of gravity from water return pipeline, therefore the water that enters branch pipe(tube) does not only have bigger impurity, and the power that sampling needs is little, impulsive force to filter screen and sampler is little, has effectively prolonged the serviceable life of filter screen and sampler.
2, sampler of the present utility model and branch pipe(tube) are convenient to the maintenance and the cleaning of sampler for flexibly connecting.
Description of drawings
Accompanying drawing is a structural representation of the present utility model;
Among the figure, 1. picotan; 2. trunk line; 3. branch pipe(tube); 4. pipe sampler; 5. sampling pump; 6. return line; 61. inlet pipeline; 62. water return pipeline; 7. filter screen; 8. on-line monitoring instrument.
Embodiment
As shown in drawings, the water quality monitoring sampler comprises picotan 1, the trunk line 2 that is communicated with picotan 1, and the branch pipe(tube) 3 that is communicated with trunk line 2 with the water fetching device that branch pipe(tube) 3 is connected, is communicated with return line 6 between described branch pipe(tube) 3 and the described trunk line 2.
Described return line comprises inlet pipeline 61 and water return pipeline 62, and described inlet pipeline 61 and water return pipeline 62 two ends are communicated with described trunk line 2 and branch pipe(tube) 3 respectively.
Described water fetching device comprises the sampling pump 5 that is communicated with described branch pipe(tube) 3, the pipe sampler 4 that is communicated with described sampling pump 5.
Be provided with filter screen 7 before the pipe sampler 4 on described branch pipe(tube) 3.
Described pipe sampler 4 is flexible connection with the connected mode of branch pipe(tube) 3.
Described water return pipeline 62 is an acute angle with the angle of trunk line 2.
During the utility model work, by picotan 1 with water suction trunk line 2, the current of trunk line 2 are when return line 6, inertia by current enters inlet pipeline 61, and in the intersection of inlet pipeline 61 with water return pipeline 62, the impurity that particle and weight are bigger in the water by the effect of gravity from water return pipeline 62 trunk line 2 that refluxes back, relatively than the filtration of clean water through filter screen 7, further filter the impurity of removing in the water, then through pipe sampler 4, enter branch pipe(tube) 3, by sampling pump 5 water sample is sent to on-line monitoring instrument 8 and detect.
