Description

Technical Field

[0001] This utility model relates to the technical field of permanganate index analyzers, and more specifically, to a permanganate index analyzer that facilitates the collection of water vapor. Background Technology

[0002] Permanganate index analyzers generate a large amount of water vapor during water bath digestion. This vapor accelerates the aging of internal components and poses safety hazards. Currently, the common practice is to use an open-shell design to prevent moisture buildup. However, this open-shell structure allows dust and impurities from the air to easily enter the instrument, affecting the accuracy of the internal optical detection modules. Furthermore, the instrument contains a three-axis motion mechanism, and the lack of a protective shell increases the risk of injury to operators. Therefore, installing a protective shell with an exhaust fan at an appropriate location on the shell can effectively remove the large amount of water vapor generated during water bath digestion. However, this exhausted water vapor may adhere to other equipment and instruments in the machine room, potentially affecting their normal operation.

[0003] Therefore, a permanganate index analyzer that facilitates the collection of water vapor is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a permanganate index analyzer that facilitates the collection of water vapor.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A permanganate index analyzer for easy collection of water vapor includes a housing with a digestion station inside, where several sample cups are placed. The housing is equipped with a steam drainage mechanism and a steam collection mechanism. The steam drainage mechanism includes an air inlet on the left side of the housing, a right exhaust outlet on the right side of the housing, and an upper exhaust outlet on the top of the housing. Exhaust fans are installed at both the right exhaust outlet and the upper exhaust outlet. The digestion station is located below the upper exhaust outlet. The steam collection mechanism is connected to both the right exhaust outlet and the upper exhaust outlet.

[0007] Furthermore, in this utility model, the aforementioned water vapor collection mechanism includes a first pipe connected to the right exhaust vent, a second pipe connected to the upper exhaust vent, and a liquid storage tank. The end of the first pipe away from the right exhaust vent and the end of the second pipe away from the upper exhaust vent are both connected to the liquid storage tank. A cooling rod is installed inside both the first pipe and the second pipe. An automatic liquid drainage mechanism is also installed inside the liquid storage tank.

[0008] Furthermore, in this utility model, a partition is provided inside the liquid storage tank, which divides the interior of the liquid storage tank into a left chamber and a right chamber. The end of the first pipe away from the right exhaust port and the end of the second pipe away from the upper exhaust port are both connected to the left chamber. A through hole is provided on the partition near the bottom of the liquid storage tank. The automatic draining mechanism is located in the right chamber.

Detailed Implementation

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Please see Figure 1 and Figure 2 This utility model provides a technical solution:

[0017] A permanganate index analyzer for easy water vapor collection includes a housing 101, within which a digestion station 201 is provided, holding several sample cups. A three-axis motion mechanism is also installed within the housing 101 to facilitate placing the sample cups on the digestion station 201. The housing 101 is equipped with a steam drainage mechanism and a steam collection mechanism. The steam drainage mechanism includes an air inlet 301 on the left side of the housing 101, a right exhaust vent 302 on the right side of the housing 101, and an upper exhaust vent 303 at the top of the housing 101. Exhaust fans are installed at both the right exhaust vent 302 and the upper exhaust vent 303. The digestion station 201 is located below the upper exhaust vent 303. The steam collection mechanism is connected to both the right exhaust vent 302 and the upper exhaust vent 303. The number of exhaust fans can be installed according to actual needs.

[0018] Specifically, in this embodiment, the water vapor collection mechanism includes a first pipe 401 connected to the right exhaust port 302, a second pipe 402 connected to the upper exhaust port 303, and a storage tank 403. The end of the first pipe 401 furthest from the right exhaust port 302 and the end of the second pipe 402 furthest from the upper exhaust port 303 are both connected to the storage tank 403. Cooling rods 404 are installed in both the first pipe 401 and the second pipe 402. An automatic drainage mechanism is also installed in the storage tank 403. Thus, when the instrument is working, the large amount of water vapor generated at the digestion position 201 can enter the first pipe 401 and the second pipe 402 under the action of the exhaust fan. In addition, an exhaust valve (not shown in the figure) is installed on the storage tank 403 to discharge excess air from the storage tank 403.

[0019] like Figure 2 As shown, in this embodiment, a partition 501 is provided inside the liquid storage tank 403, which divides the interior of the liquid storage tank 403 into a left chamber 502 and a right chamber 503. The end of the first pipe 401 away from the right exhaust port 302 and the end of the second pipe 402 away from the upper exhaust port 303 are both connected to the left chamber 502. A through hole is provided on the partition 501 near the bottom of the liquid storage tank 403. An automatic draining mechanism is provided in the right chamber 503.

[0020] In this embodiment, the automatic drainage mechanism includes a floating airbag 601 disposed in the right chamber 503, a moving contact 602 disposed on the top of the floating airbag 601, a stationary contact 603 disposed on the top of the right chamber 503, a drainage pipe 604 communicating with the left chamber 502, and an electrically controlled valve 605 disposed on the drainage pipe 604. Both the moving contact 602 and the stationary contact 603 can be electrically connected to the electrically controlled valve 605 through wires. A first magnetic ring 606 is disposed on the moving contact 602, and a second magnetic ring 607 with the opposite magnetic properties to the first magnetic ring 606 is disposed on the stationary contact 603. When the first magnetic ring 606 and the second magnetic ring 607 are attracted together, the moving contact 602 abuts against the stationary contact 603.

[0021] Working principle:

[0022] When the instrument is working, the water inside digestion station 201 is in a state of slight boiling (or boiling) when it begins to heat up. When the robotic arm inside the instrument places the sample cup into digestion station 201 to begin digestion, a large amount of water vapor is generated. This water vapor enters the first pipe 401 and the second pipe 402 under the action of the exhaust fans at the upper exhaust port 303 and the right exhaust port 302. The flowing water vapor cools down and liquefies as it passes through the cooling rod 404, and the liquid flows into the left chamber 502. As the experiment continues, water vapor is continuously generated, and the amount of water liquefied by the cooling rod 404 continues to increase. (Refer to...) Figure 2 As the liquid level in the left chamber 502 gradually rises, the liquid level in the right chamber 503 rises synchronously, causing the floating airbag 601 to gradually move upward under the buoyancy of the water. When the first magnetic ring 606 and the second magnetic ring 607 are magnetically attracted together, the moving contact 602, the stationary contact 603, and the electrically controlled valve 605 form a series circuit. When the electrically controlled valve 605 operates, the water in the storage tank 403 can be discharged through the drain pipe 604. When the water in the storage tank 403 is drained, the first magnetic ring 606 and the second magnetic ring 607 can separate, and the electrically controlled valve 605 can then block the drain pipe 604.
