Technical Field

[0001] This utility model relates to the field of perchloric acid ventilation technology, and in particular to an automatic dosing and water supply system for perchloric acid fume hoods. Background Technology

[0002] A perchloric acid fume hood is a fume hood specifically designed for handling perchloric acid. It is used in laboratories and other similar locations, primarily for the safe conduct of experiments involving perchloric acid. A dedicated ventilation system effectively removes the harmful gases produced by the volatilization of perchloric acid, preventing their accumulation indoors.

[0003] Perchloric acid is highly corrosive and oxidizing, and manual addition poses safety hazards; even slight carelessness can cause serious harm to the human body. Furthermore, manual water addition cannot monitor the tank level and liquid status in real time, easily leading to situations such as the tank drying out and damaging equipment, or liquid overflow and polluting the environment.

[0004] Therefore, this utility model provides an automatic dosing and water supply system for perchloric acid fume hoods. Utility Model Content

[0023] 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.

[0024] like Figure 1 - Figure 2As shown, this embodiment provides a technical solution: an automatic dosing and water supply system for a perchloric acid fume hood, including an installation frame 1 and a drainage component 2. The drainage component 2 includes a water tank 21 fixedly connected inside the installation frame 1, a drain pipe 22 fixedly connected to the outside of the water tank 21, a drain switch 4 installed on the outside of the drain pipe 22, a pumping pipe 23 fixedly connected to the outside of the water tank 21, an overflow pipe 24 fixedly connected to the outside of the water tank 21, a water pump 25 fixedly connected to the inner wall of the installation frame 1, a water supply pipe 26 fixedly connected to the output end of the water pump 25, and a water inlet pipe 25 fixedly connected to the input end of the water pump 25 on the pumping pipe 23.

[0025] The mounting frame 1 serves as the foundation for all components of the system, providing stable support and fixed positions for other parts, ensuring relative stability during operation, and facilitating installation, maintenance, and repair. The water tank 21 stores and temporarily holds liquids such as perchloric acid, providing a liquid source for the system's dosing and water supply operations. The drain pipe 22 drains the liquid from the water tank 21, facilitating maintenance and cleaning, and preventing problems such as impurity sedimentation and bacterial growth caused by prolonged liquid accumulation. The drain switch 4 controls the opening and closing of the drain pipe 22, achieving precise control of the drainage process, avoiding disorderly liquid discharge, and allowing the drain to be turned on or off at any time according to actual needs. This convenient operation reduces liquid waste. The suction pipe 23 connects to the water pump 25 and... The water tank 21 enables the water pump 25 to draw liquid from the water tank 21, providing a liquid source for the water pump 25, realizing the transportation and recycling of the liquid, and ensuring the normal water supply function of the system. The overflow pipe 24 discharges excess liquid when the liquid level in the water tank 21 is too high, preventing liquid overflow, protecting the water tank 21 and the surrounding environment, and avoiding equipment damage, safety hazards and environmental pollution caused by liquid overflow. The water pump 25 draws liquid from the water tank 21 through the water suction pipe 23 and transports the liquid to the required parts through the water supply pipe 26, providing the power for liquid transportation, realizing automatic water supply and circulation of the liquid. The water supply pipe 26 transports the liquid transported by the water pump 25 to the designated location in the fume hood for the treatment or dilution of perchloric acid.

[0026] like Figure 1 and Figure 3 As shown, the detection component 3 includes a detection device 31 fixedly connected to the top of the water tank 21, an alkali tank 34 fixedly connected inside the mounting frame 1, an alkali pump 33 fixedly connected to the top of the alkali tank 34, the output end of the alkali pump 33 fixedly connected to the water tank 21, the detection device 31 is provided at the top of the water tank 21, and a water outlet 32 ​​is provided at the top of the water tank 21.

[0027] The detection device 31 monitors the liquid status in the water tank 21 in real time, providing accurate data support for the dosing system, ensuring that the liquid quality meets the process requirements, and promptly detecting and handling abnormal liquid conditions. The inlet 32 ​​serves as the inlet for liquids such as perchloric acid to enter the water tank 21, facilitating timely replenishment of the water tank 21, ensuring sufficient liquid supply to the system, simplifying operation, and improving work efficiency. The alkali tank 34 stores alkali solution, used to adjust or neutralize the concentration of perchloric acid to achieve a suitable usage state. The alkali pump 33 transports the alkali solution from the alkali tank 34 to the water tank 21, where it mixes or reacts with the perchloric acid, realizing automatic addition and precise control of the alkali solution.

[0028] Working principle:

[0029] like Figure 1 - Figure 3 As shown:

[0030] In operation: First, perchloric acid liquid is introduced into water tank 21 through inlet 32. Water tank 21 is used to store and temporarily store liquids such as perchloric acid, providing a liquid source for the system's dosing and water supply operations. The detection device 31 in water tank 21 monitors the liquid in real time, providing accurate data support for the dosing system, promptly detecting and handling liquid anomalies, and ensuring that the liquid quality meets process requirements. When water supply to the fume hood is required, water pump 25 starts. The input end of water pump 25 draws liquid from water tank 21 through water pipe 23, which then drives the output end of water pump 25 to deliver the liquid to water supply pipe 26. Water supply pipe 26 delivers the liquid to a designated location within the fume hood for the treatment or dilution of perchloric acid. This achieves automatic water supply and recycling of the liquid, ensuring the system's water supply efficiency. During normal water supply, if the liquid level in water tank 21 is too high during liquid transportation, the overflow pipe 24 will discharge the excess liquid to prevent overflow and protect water tank 21 and the surrounding environment. This avoids equipment damage, safety hazards, and environmental pollution caused by liquid overflow. When water tank 21 needs maintenance and cleaning, the drain switch 4 will be opened, and the drain pipe 22 will drain the liquid from water tank 21, preventing problems such as impurity precipitation and bacterial growth caused by long-term liquid accumulation. At the same time, the drain can be turned on or off at any time according to actual needs, which is convenient to operate and reduces liquid waste. If it is necessary to adjust or neutralize the concentration of perchloric acid, the alkali pump 33 will be started to transport the alkali solution in alkali tank 34 to water tank 21 to mix or react with perchloric acid, realizing automatic addition and precise control of alkali solution.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
