Abstract
Description
Technical Field
[0001] This utility model relates to the field of metering storage tank technology, and more specifically, to a safety storage device for a heightened nitric acid solution metering tank. Background Technology
[0002] Metering storage tanks play a vital role in various fields such as daily life and chemical enterprises. With the continuous increase in demand in life and the continuous expansion and development of production enterprises, there may be situations where the initial engineering design can no longer meet the production and storage needs.
[0003] Replacing the entire metering storage system would not only be a large investment and too expensive, but would also result in waste due to the equipment not reaching its service life. Therefore, it is advisable to consider improving the existing metering storage system to meet the company's development needs and achieve the goal of safe production. Utility Model Content
[0004] In view of this, the present invention proposes a safety storage device for a heightened nitric acid solution metering tank, the specific technical solution of which is as follows:
[0005] A heightened nitric acid solution metering tank safety storage device includes a main body of the original solution metering tank, a heightened section of the metering tank, and a top cover of the metering tank. The heightened section of the metering tank has the same cross-sectional shape as the main body of the original solution metering tank and is fixedly connected to the upper part of the main body of the original solution metering tank. The top cover of the metering tank is installed at the upper port of the heightened section of the metering tank. An inlet for connecting to a feed pipeline is provided on the side wall of the heightened section of the metering tank, and an inlet valve is provided on the feed pipeline. The outlet pipeline and the heating pipeline remain connected to the side wall of the main body of the original solution metering tank, and each of the outlet pipeline and the heating pipeline is provided with a corresponding pipeline opening and closing valve.
[0006] Preferably, the height of the metering tank elevation section is 1 to 2 meters.
[0007] Preferably, the metering tank top cover is fitted with a sealing buckle at the upper port of the metering tank elevation section.
[0008] Preferably, the top vent pipe is connected to the upper part of the metering tank top cover.
[0009] This invention adds a metering tank elevation section above the original solution metering tank body, thereby increasing the height of the metering tank itself. This enables the nitric acid metering tank to meet current and future production needs, which is beneficial for continuous and stable production operation.
[0010] Furthermore, since the device of this invention requires heating after metering, raising its height eliminates concerns about overflow caused by boiling of the solution in the metering tank during heating. At the same time, the device of this invention will not cause instantaneous overflow of the solution due to metering instrument malfunction or human error during use, thereby reducing the probability of potential safety hazards in production.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0017] Example:
[0018] like Figure 1 As shown, the present invention provides a heightened nitric acid solution metering tank safety storage device, comprising the original solution metering tank body 1, the metering tank heightening section 2, and the metering tank top cover 3.
[0019] The cross-sectional shape of the metering tank extension section 2 is consistent with that of the original solution metering tank body 1. The metering tank extension section 2 is generally adapted and fixed to the upper part of the original solution metering tank body 1 by welding. The metering tank top cover 3 is installed at the upper port of the metering tank extension section 2. That is, the metering tank top cover 3, which was originally adapted and installed at the upper port of the original solution metering tank body, is removed and reinstalled at the upper port of the metering tank extension section 2.
[0020] The side wall of the heightened section 2 of the metering tank is provided with an inlet port connected to the feed line 4, and the feed line 4 is provided with a feed valve 5; the discharge line 6 and the heating line remain connected to the side wall of the original solution metering tank body 1, and the discharge line 6 and the heating line are respectively provided with pipeline opening and closing valves.
[0021] In a further specific embodiment, the height of the metering tank extension section 2 is 1 to 2 meters, preferably 1 meter. Furthermore, the metering tank top cover 3 is fitted with a sealing buckle at the upper port of the metering tank extension section 2. The top vent pipe 7 is connected to the upper part of the metering tank top cover 3.
[0022] In actual operation, the workers removed the metering tank top cover 3 from the original metering tank body 1, then directly welded the metering tank elevation section 2, increasing the height of the original metering tank body 1 by 1 meter. Afterwards, the top cover was replaced, and the vent pipe 7 was simultaneously increased by 1 meter and reconnected to the metering tank top cover 3. The feed pipeline and corresponding valves were raised (i.e., the feed port on the original metering tank body was sealed), while the discharge pipeline and corresponding valves, and the heating pipeline and corresponding valves remained unchanged. The modification of the existing metering tank was achieved by increasing its own height. Once the nitric acid solution enters the metering tank and reaches the set value, steam heating begins. Only after the temperature reaches the set temperature can the next step of the operation be performed.
[0023] Introducing this utility model device can greatly improve the on-site working environment at a relatively low cost, thereby increasing production efficiency and providing necessary guarantees for safe production in enterprises.
[0024] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments.
