Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically to a water quality monitoring instrument with a water sample and reagent bubbling and mixing device. Background Technology

[0002] Water quality monitoring reagent digestion refers to the process of converting complex substances such as organic matter and suspended solids in water samples into simpler, more easily measurable forms. During digestion, the reagent reacts chemically with the target substances in the water sample. Stirring ensures thorough mixing of the reagent and water sample, allowing for more uniform contact between reactants and increasing their chances of collision, thereby accelerating the reaction rate and making the digestion process more efficient.

[0003] Traditional reagent digestion and stirring methods include two approaches: magnetic stirring and mechanical stirring. Magnetic stirring, however, can weaken over time under high temperatures. The latter, described in CN221156399U, is a pharmaceutical reagent stirring device. This device includes a reagent stirring housing with a top cover. A drive motor is mounted on the top cover, and the motor's output passes through the top cover and is fixedly connected to a stirring rod inside the housing. Stirring blades are symmetrically mounted on the outer surface of the stirring rod, and a scraping mechanism is fixed at the ends of the two blades to remove residues from the inner wall of the mixing housing. This application, by incorporating a drive motor, stirring rod, scraping mechanism, lower receiving plate, and upper receiving plate, enables large-volume stirring of the mixed drugs within the device. Simultaneously, it scrapes away residues adhering to the inner wall, which are then collected by the lower and upper receiving plates, thus removing the residues and facilitating the cleaning and scraping of the inner wall by pharmaceutical laboratory technicians. Mechanical stirring shafts require relative rotation with the cavity, which can lead to leaks at the seals or necessitates the use of complex mechanical seals. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water sample reagent bubbling and mixing device for a water quality monitoring instrument, which solves the problem of easy leakage at gaps in the mechanical stirring of the reagent digestion device mentioned in the background technology.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The water sample reagent bubbling and mixing device of this water quality monitor is equipped with a bubble generating mechanism.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1-5 A water quality monitoring instrument reagent bubbling mixing device includes a reagent digestion chamber 1, a bubble generating mechanism 2 disposed at the lower part of the reagent digestion chamber 1, an exhaust port 3 disposed at the upper part of the reagent digestion chamber 1, and an air inlet pipe 4 supplying the reagent digestion chamber 1 to the bubble generating mechanism 2. The bubble generating mechanism 2 includes a nozzle 201, an air inlet 208 communicating with the air inlet pipe 4, and a liquid inlet 202 communicating with the air inlet 208. A nozzle hole 203 communicating with the air inlet 208 and the liquid inlet 202 is disposed on the bottom side wall of the nozzle 201. With this configuration, gas and liquid are mixed and discharged from the nozzle hole 203 to generate bubbles. As the bubbles rise, they drive the liquid to mix. This configuration can fully mix the reagents in the reagent digestion chamber 1, while the reagent digestion chamber 1 is a closed space to prevent leakage.

[0023] The liquid inlet section 202 is connected to and has a liquid inlet pipe 204. A pump 205 is provided between the liquid inlet pipe 204 and the liquid inlet section 202. The liquid inlet end of the liquid inlet pipe 204 is parallel to the axis of the reagent digestion chamber 1. The surface of the liquid inlet pipe 204 is provided with a liquid inlet hole 206. With this arrangement, liquid can be drawn from different heights.

[0024] The inlet pipe 204 has an inverted "U" shaped cross-section. The pump 205 is located in the middle of the inlet pipe 204. A tee 207 is provided in the inlet pipe 204 between the inlet section 202 and the pump 205. The other inlet of the tee 207 is connected to and through the air inlet pipe 4. With this arrangement, after the pump 205 stops working, the liquid falls back under the action of gravitational potential energy. By switching the tee 207 to connect the air inlet pipe 4 and the inlet section 202, the residual liquid can be discharged by airflow.

[0025] A liquid supply pipe 5 is provided above the reagent digestion chamber 1. The reagent to be digested can be supplied into the interior of the reagent digestion chamber 1 through the liquid supply pipe 5. A drain pipe 6 is connected and passes through the lower side wall of the reagent digestion chamber 1. The liquid can be completely discharged by limiting the position of the drain pipe 6.

[0026] A one-way valve 7 is provided at the end of the vent 3 away from the reagent digestion chamber 1. An absorption mechanism 8 for absorbing reagents is provided at the end of the one-way valve 7 away from the vent 3. The absorption mechanism 8 is adjusted according to the reaction reagents. The reagents inside the absorption mechanism 8 react with the reaction reagents to generate non-polluting products. The one-way valve 7 can prevent gas backflow. By setting up the absorption mechanism 8, the reagents carried out by the gas can be absorbed, thereby avoiding emission pollution.

[0027] The end of the air inlet pipe 4 away from the reagent digestion chamber 1 is connected to and passes through an air supply unit 9. The air supply unit 9 is determined according to the digestion reagent, such as carbon dioxide gas, nitrogen gas, etc., which do not react with the digestion reagent. Generally, the gas is placed in a pressure bottle and connected to the air inlet pipe 4 through a threaded connection. A filter unit 10 is set between the reagent digestion chamber 1 and the air supply unit 9 in the air inlet pipe 4. The filter unit 10 filters the gas to prevent impurities in the gas from entering the reagent digestion chamber 1.

[0028] In use, first turn on the gas supply unit 9 to continuously inject airflow into the reagent digestion chamber 1. At this time, the digestion reagent is injected into the reagent digestion chamber 1 through the liquid inlet pipe 204. The reagent is extracted by the pump 205 and mixed with the gas through the liquid inlet 202 and sprayed out from the nozzle 203, generating bubbles to carry the reagent to mix. After the mixing is completed, the drain pipe 6 is opened and the reagent is discharged from the drain pipe 6. Turn off the pump 205 and switch the three-way valve 207 to allow the gas to pass through the liquid inlet 202, thereby discharging the reagent remaining in the liquid inlet pipe 204. After the reagent is discharged, turn off the gas supply unit 9.

[0029] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
