Description

Technical Field

[0001] This utility model relates to the field of parallel water sample dispensing, and in particular to a water sample parallel dispensing device. Background Technology

[0002] In environmental monitoring sampling, the collection of parallel samples from river, lake, reservoir surface water, and industrial wastewater is a crucial step in ensuring quality control for both sampling and analysis. Poorly collected parallel samples directly impact analytical results and hinder environmental management assessments. Currently, parallel sampling of river, lake, reservoir surface water, and industrial wastewater typically involves filling two separate bottles with the samples individually. While these bottles are filled with the same scoop of water, the water's properties and operator error can lead to uneven mixing, resulting in significant discrepancies between the two samples and failing to meet quality control requirements for parallel sample collection.

[0003] Chinese utility model patent CN208297229U discloses a parallel water sample dispenser that employs a variable-diameter flow channel composed of alternating funnel-cylindrical cavity-spherical cavity. It utilizes the turbulence generated at the diameter changes to mix the fluid before dispensing it through a three-way pipe. While this design achieves a combination of mixing and dispensing, its mixing method is passive, resulting in limited mixing intensity. Furthermore, the dispensing principle of the aforementioned prior art is based on isochronous flow splitting rather than isovolute flow splitting, leading to homogeneity errors. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the aforementioned problems in the prior art, this utility model provides a parallel water sample dispensing device.

[0006] (II) Technical Solution

[0008] A parallel water sample dispensing device includes a water sample mixing mechanism, which includes a mixing tube and a water wheel. The mixing tube has a mixing chamber inside, and the top and bottom of the mixing chamber have an inlet and an outlet, respectively. The water wheel is installed inside the mixing chamber, and a rotating shaft is provided at the center of each side of the water wheel. The inner wall of the mixing chamber has a rotating groove corresponding to the rotating shaft.

[0010] The base has two drainage outlets arranged symmetrically on the left and right sides at its bottom;

[0011] The sample distribution tube is connected to the drain outlet;

[0012] The arc-shaped water guide plate is vertically arranged on the upper surface of the base, corresponding to the drain outlet, and the opening of the arc-shaped water guide plate faces the drain outlet;

[0013] The bracket is fixedly mounted on the base and positioned between the two drain outlets;

[0014] The tipping bucket is equipped with a tilting shaft on both the front and rear sides, and the tipping bucket is rotatably connected to the bracket through the tilting shaft.

[0015] The top cover is mounted on the base, and the top of the top cover is connected to the mixing tube;

[0016] The limiting plate is provided on the inner wall of the arc-shaped water guide plate;

[0020] Preferably, a liquid collecting funnel is connected to the liquid inlet at the top of the mixing tube.

[0021] (III) Beneficial Effects

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. The water sample enters the mixing chamber through the inlet and falls onto the water wheel, driving the water wheel to rotate. The mechanical action of the water wheel rotation directly shears the fluid, generating strong turbulence to achieve mixing. The mechanical stirring force provided by the water wheel is much greater than that of passive turbulence, which can effectively break up clumps and prevent sedimentation, greatly improving the mixing intensity of the water sample, thereby meeting the needs of different water samples for dispensing.

[0024] 2. The water sample, after being mixed by the water sample mixing mechanism, enters the base and falls into one of the tipping buckets. When the accumulated water reaches a certain weight, the tipping bucket loses its balance and tipes downward, pouring the water in the tipping bucket into the arc-shaped water guide plate and out through the drain outlet. This delivers a quantitative amount of water sample to the sample distribution tube. The tipping bucket collects the mixed water sample that has flowed in over a period of time and sends it out as a complete sample. The two sub-samples come from the same homogeneous parent sample, ensuring the homogeneity and comparability of the data. Attached Figure Description

[0034] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Please refer to Figures 1 to 3 This utility model provides a water sample parallel dispensing device, including a water sample mixing mechanism 1. The water sample mixing mechanism 1 includes a mixing tube 11 and a water wheel 13. A mixing chamber is opened inside the mixing tube 11. An inlet 12 and an outlet 14 are opened at the top and bottom of the mixing chamber, respectively. The water wheel 13 is installed in the mixing chamber. A rotating shaft is provided at the center of both sides of the water wheel 13. A rotating groove corresponding to the rotating shaft is opened on the inner wall of the mixing chamber.

[0036] In use, the water sample enters the mixing chamber through the inlet 12 and falls onto the water wheel 13, driving the water wheel 13 to rotate. The mechanical action of the rotating water wheel 13 directly shears the fluid, generating strong turbulence to achieve mixing. The mechanical stirring force provided by the water wheel 13 is much greater than that of passive turbulence, which can effectively break up clumps and prevent sedimentation, greatly improving the mixing intensity of the water sample, thereby meeting the dispensing requirements of different water samples.

[0037] refer to Figure 2 and Figure 3 In this embodiment, an automatic quantitative dispensing mechanism 2 is also included. The automatic quantitative dispensing mechanism 2 includes a base 21, a top cover 22, a bracket 23, a tipping bucket 25, a limiting plate 24, a sample dispensing tube 28, and an arc-shaped water guide plate 26.

[0038] The bottom of the base 21 has two drainage outlets 27 arranged symmetrically on the left and right sides;

[0039] The sample tube 28 is connected to the drain outlet 27;

[0040] The arc-shaped water guide plate 26 is vertically installed on the upper surface of the base 21, corresponding to the drain outlet 27, and the opening of the arc-shaped water guide plate 26 faces the drain outlet 27.

[0041] The bracket 23 is fixedly mounted on the base 21 and positioned between the two drain outlets 27;

[0042] The tipping bucket 25 is equipped with tilting shafts on both the front and rear sides, and the tipping bucket 25 is rotatably connected to the bracket 23 through the tilting shafts;

[0043] The top cover 22 is placed on the base 21, and the top of the top cover 22 is connected to the mixing pipe 11;

[0044] A limiting plate 24 is provided on the inner wall of the arc-shaped water guide plate 26;

[0045] When the tipping bucket 25 reaches its highest tilt position, it is restricted by the limiting plate 24, and the limiting plate 24 blocks one side opening of the tipping bucket 25, so that the remaining opening of the tipping bucket 25 is aligned with the liquid outlet 14 of the mixing tube 11.

[0046] In use, the water sample mixed by the water sample mixing mechanism 1 enters the base 21 and falls into one of the tipping buckets 25. When the accumulated water reaches a certain weight, the tipping bucket 25 loses its balance and tipes downward, pouring the water in the tipping bucket 25 into the arc-shaped water guide plate 26 and out through the drain outlet 27, thereby delivering a quantitative water sample to the sample tube 28. The tipping bucket 25 collects the mixed water sample that flows in over a period of time and sends it out as a complete sample at the same time. The two sub-samples come from the same homogeneous parent sample, ensuring the homogeneity and comparability of the data.

[0047] In this embodiment, the sample tube 28 is a three-way tube.

[0048] In this embodiment, the base 21 is provided with a plurality of support rods 3, and the bottom of the support rods 3 is provided with feet.
