Description

Technical Field

[0001] The utility model belongs to the technical field of water quality sampling, and in particular relates to a novel automatic water treatment sampler. Background Art

[0002] At present, in water treatment, it is usually necessary to use an automatic sampler to sample the treated water. The existing water treatment automatic sampler includes a sampler shell, on which a pump for driving the flow of water is installed, and a rack for placing sampling bottles is arranged inside the sampler shell. Since the same batch of sampling requires two water samples to be collected, one for inspection and one for storage, this automatic sampler is usually used to sample twice in succession when in use. Therefore, the successive sampling may cause errors in the samples sent for inspection and the samples stored. In addition, when this sampler is in use, there is no cleaning component for cleaning the pump and pipelines, which increases the difficulty of cleaning during use. Utility Model Content

[0017] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 and attached Figure 2 As shown, a novel automatic sampler for water treatment includes a sampler housing 1, a touch-screen single-chip microcomputer controller is installed on the rear side of the sampler housing 1, and the single-chip microcomputer controller is electrically connected to a sampling pump 2 to realize the function of automatic sampling. The sampling pump 2 is detachably installed on the front side of the sampler housing 1, a handle 3 is detachably installed on the upper part of the sampler housing 1, and a sampling bottle rack 4 is detachably installed inside the sampler housing 1, and the sampling bottle rack 4 is used to place sampling bottles.

[0018] In this embodiment, combined with the Figure 3As shown, a water inlet hose 25 is threadedly connected to the water inlet of the sampling pump 2, a water outlet tee 21 is threadedly connected to the water outlet of the sampling pump 2, and connecting elbows 22 are threadedly connected to the left and right ends of the water outlet tee 21. The water outlet tee 21 divides the sampled water into two paths to achieve the function of simultaneous sampling, and the comparison between subsequent test samples and retained samples is more accurate. The lower end of each connecting elbow 22 is threadedly connected to a telescopic tube 23. When sampling, the user extends the lower end of the sampling tube 23 into the sampling bottle to avoid water splashing during sampling. The telescopic tube 23 adopts a PP telescopic tube, and an annular sheet 24 is glued to the outside of the middle and lower ends of the telescopic tube 23, and the annular sheet 24 is made of PP material.

[0019] In this embodiment, specifically, a water inlet tee 26 is provided at one end of the water inlet hose 25 away from the sampling pump 2, a connecting pipe 28 is integrated at the middle and lower part of the left end of the water inlet tee 26, the end of the connecting pipe 28 away from the water inlet tee 26 is threadedly connected to the end of the water inlet hose 25 away from the sampling pump 2, and the upper end and the right end of the water inlet tee 26 are both threadedly connected with a threaded column 27. After the sampling is completed. When cleaning with external clean water, the water inlet tee 26 is blocked with an external pipe cap, the upper threaded column 27 is rotated upward, the right threaded column 27 is removed, and the right end of the water inlet tee 26 is connected to the cleaning water. The cleaning water is used to clean the water inlet tee 26, the water inlet hose 25, the sampling pump 2, the water outlet tee 21, the connecting elbow 22 and the telescopic tube 23, thereby avoiding contamination between the water samples sampled each time.

[0020] In the present embodiment, specifically, the interior of the connecting pipe 28 is connected to the interior of the water inlet tee pipe 26 .

[0021] In this embodiment, specifically, the height of the connecting pipe 28 is lower than the right end of the water inlet tee pipe 26 .

The user puts the lower end of the telescopic tube 23 into the mouth of the sampling bottle to prevent water from splashing out from the upper part of the sampling bottle during sampling, and the annular sheet 24 is stuck on the upper part of the mouth of the sampling bottle to prevent the telescopic tube 23 from entering the bottom of the sampling bottle. When sampling, the lower end of the water inlet tee 26 is connected to the water to be sampled, and the water sample enters the sampling bottle through the water inlet hose 25, the water outlet tee 21, the connecting elbow 22 and the telescopic tube 23 under the drive of the sampling pump 2.
