Description

Technical Field

[0001] This utility model relates to the field of sulfuric acid sampling technology, specifically to a sulfuric acid container that facilitates sampling. Background Technology

[0002] Sulfuric acid tanks are primarily made of carbon steel, fiberglass, and plastics (such as polyethylene (PE) and polypropylene (PP). Carbon steel sulfuric acid tanks are the most common in the domestic market and among enterprises, used for storing sulfuric acid with a concentration of over 90%. Carbon steel can form a passivation protective film in concentrated sulfuric acid, thus exhibiting strong corrosion resistance; however, attention must be paid to welding processes and preventing defects such as pinholes to avoid severe corrosion problems. Fiberglass and plastic tanks offer even better corrosion resistance, are suitable for storing sulfuric acid of various concentrations, and have a long service life.

[0003] Chinese patent (authorization announcement number: CN 213022447 U, authorization announcement date: 2021.04.20) proposes a sulfuric acid tank sampling device. This utility model, by setting a cover plate and a sampling steel pipe, makes the sampling process more convenient and simpler than the traditional sampling method. It also eliminates the need to remove the fixing screws, thereby avoiding the problem of foreign matter falling into the finished acid tank and affecting the quality of sulfuric acid, thus making the sampling safer.

[0004] However, during the use of the above equipment, the staff still need to open the tank to take samples of sulfuric acid. If the staff does not take proper protective measures, they may be injured. In addition, the moisture in the air may affect the concentration of sulfuric acid. Therefore, sulfuric acid should not be exposed to the air for a long time. In order to improve the safety of sulfuric acid sampling and to prevent moisture in the air from entering the tank during sampling, we propose a sulfuric acid tank that is easy to sample.

A fixing frame is installed on the sampling tube, with several limiting posts at the bottom of the frame. A rotating disc is mounted on the bottom of one set of limiting posts, allowing the sampling bottle to be placed inside the fixing frame. This prevents workers from coming into contact with sulfuric acid during sampling. Simultaneously, the bamboo fiber layer embedded in the vent tube prevents moisture from the air from entering the storage container during sampling, effectively preventing the influence of air moisture on the sulfuric acid concentration within the storage container and solving the problems mentioned earlier.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

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] Please see Figure 1-6 This utility model provides a technical solution: a sulfuric acid tank for easy sampling, including a storage tank 1, a discharge assembly 2 installed at the bottom of the storage tank 1, the discharge assembly 2 including an L-shaped tube 6, the L-shaped tube 6 being fixedly connected to the inner chamber of the storage tank 1, a diversion tube 7 being fixedly connected to the L-shaped tube 6, a sampling tube 9 being fixedly connected below the diversion tube 7, a first manual valve 12 being installed on the sampling tube 9, a fixing frame 13 being fixedly installed on the diversion tube 7, a plurality of limiting posts 15 being fixedly installed at the bottom of the fixing frame 13, a circular plate 16 being rotatably installed at the bottom of one set of limiting posts 15, a sampling bottle 14 being placed on the circular plate 16, and the bottom of the sampling tube 9 extending into the sampling bottle 14; a vent pipe 5 being fixedly connected to the top of the storage tank 1, a bamboo fiber layer being fixedly embedded in the vent pipe 5, and a second threaded cap being threadedly connected to the top of the vent pipe 5; and graduations being marked on the sampling bottle 14;

[0025] In use, remove the second threaded cap connected to the upper thread of the vent tube 5 and the third threaded cap connected to the lower thread of the sampling tube 9. Then, place the sampling bottle 14 into the fixing frame 13, allowing the sampling tube 9 to extend into the sampling bottle 14. Then, rotate the placement disc 16 to stably position the sampling bottle 14 on the placement disc 16, where the limiting post 15 restricts its position. Then, the operator opens the first manual valve 12. Subsequently, under atmospheric pressure, the sulfuric acid in the storage tank 1 enters the sampling bottle 14 through the L-shaped tube 6, the diversion tube 7, and the sampling tube 9. The sampling bottle 14 is marked with graduations, and the operator can control the timing of closing the first manual valve 12 according to the required amount of sulfuric acid. After sampling, the operator first closes the first manual valve 12. Then, hold the sampling tube 9 containing sulfuric acid firmly, rotate the placement disc 16 to remove it from the bottom of the sampling tube 9, and carefully remove the sampling tube 9 containing sulfuric acid. Then, tighten the third threaded cap to the bottom of the sampling tube 9 to improve the airtightness of the sampling tube 9. At the same time, reset the placement disc 16, and finally seal the vent pipe 5 with the second threaded cap. This effectively improves the airtightness of the storage tank 1. During sampling, the sampling bottle 14 is placed in the fixing frame 13 to avoid contact between the staff and sulfuric acid, which greatly improves the safety of sampling. At the same time, the bamboo fiber layer inside the vent pipe 5 can effectively prevent moisture in the air from entering the storage tank 1 during sampling, thereby avoiding the influence of moisture in the air on the sulfuric acid concentration in the storage tank 1.

[0026] The right side of the diversion pipe 7 is fixedly connected to the discharge pipe 8, and a second manual valve 10 is installed on the discharge pipe 8. The right end of the discharge pipe 8 is threadedly connected to a first threaded cap 11. When it is necessary to remove the sulfuric acid from the storage tank 1, the second manual valve 10 can be opened, and the sulfuric acid in the storage tank 1 can be removed through the discharge pipe 8. The first threaded cap 11 can improve the airtightness of the discharge pipe 8.

[0027] Several support columns 3 are fixedly installed at the bottom of the storage tank 1. Anti-slip pads are fixedly installed at the bottom of the support columns 3. The support columns 3 support the storage tank 1, and the protective pads can improve the stability of the entire tank when it is placed.

[0028] A feed pipe is fixedly connected to the top of the storage tank 1, and a sealing cover 4 is fixedly installed on the feed pipe by several bolts; sulfuric acid enters the storage tank 1 through the feed pipe, and the sealing cover 4 is used to seal the storage tank 1.

[0029] Working principle: Remove the second threaded cap connected to the upper thread of the vent tube 5 and the third threaded cap connected to the lower thread of the sampling tube 9. Then place the sampling bottle 14 into the fixing frame 13, allowing the sampling tube 9 to extend into the sampling bottle 14. Then rotate the placement plate 16 to stably place the sampling bottle 14 on the placement plate 16, where the limiting post 15 restricts the position. Then, the operator opens the first manual valve 12. Subsequently, under atmospheric pressure, the sulfuric acid in the storage tank 1 enters the sampling bottle 14 through the L-shaped tube 6, the diversion tube 7, and the sampling tube 9. The sampling bottle 14 is marked with graduations, and the operator can control the closing time of the first manual valve 12 according to the required amount of sulfuric acid. After sampling, the operator first closes the first manual valve 12, and then holds the sample bottle 14 by hand. The sampling tube 9 containing sulfuric acid is tightly packed. Then, the placement disc 16 is rotated to remove it from the bottom of the sampling tube 9. The sampling tube 9 containing sulfuric acid is then carefully removed. The third threaded cap is then tightened to the bottom of the sampling tube 9 to improve the airtightness of the sampling tube 9. At the same time, the placement disc 16 is reset. Finally, the vent pipe 5 is sealed with the second threaded cap. This effectively improves the airtightness of the storage tank 1. During sampling, the sampling bottle 14 is placed in the fixing frame 13 to avoid contact between the staff and sulfuric acid, which greatly improves the safety of sampling. At the same time, the bamboo fiber layer inside the vent pipe 5 can effectively prevent moisture in the air from entering the storage tank 1 during sampling, thereby preventing the sulfuric acid in the tank 1 from being in contact with moisture in the air for a long time, which would affect its concentration.

[0030] When it is necessary to remove the sulfuric acid from the storage tank 1, the second manual valve 10 can be opened to remove the sulfuric acid from the storage tank 1 through the discharge pipe 8. The first threaded cap 11 can improve the airtightness of the discharge pipe 8. The support column 3 supports the storage tank 1, and the protective pad under the support column 3 can improve the stability of the entire tank when it is placed. The sulfuric acid enters the storage tank 1 through the feed pipe, and the sealing cap 4 is used to seal the storage tank 1.
