[0002] A large horizontal ammonium nitrate solution storage tank is a special equipment for storing ammonium nitrate solution. It has a large capacity and a specific design to meet the needs of storing and transporting ammonium nitrate solution. Ammonium nitrate solution has certain corrosiveness, so the storage tank is usually made of corrosion-resistant materials such as stainless steel, fiberglass reinforced plastic, polyethylene (PE), etc. The structure of the storage tank is horizontal, which is convenient for installation, transportation and maintenance. A stirring device is usually arranged inside the storage tank to ensure that the solution remains uniform during storage;

[0003] The selection of the ammonium nitrate solution storage container is also very important. Materials with good corrosion resistance such as stainless steel containers or special plastic containers should be selected, and the airtightness of the container should be ensured to prevent moisture intrusion or solution overflow. If it is found that the ammonium nitrate solution deteriorates, such as abnormal conditions such as precipitation, odor or color change, use should be stopped immediately, and the container should be treated. Moreover, it is difficult to judge whether the ammonium nitrate solution stored inside the container has deteriorated and it needs to be taken out of the container. In this process, the airtightness of the container may be affected. Therefore, the utility model proposes a large horizontal ammonium nitrate solution storage tank to solve the above problems. Summary of the Invention

Specific embodiments

[0019] To deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0020] According to Figures 1-5 As shown, this embodiment proposes a large horizontal ammonium nitrate solution storage tank, including a liquid storage tank 1, a feed pipe 2, and a discharge pipe 3. The top of the left end of the liquid storage tank 1 is connected to the feed pipe 2, the bottom of the right end of the liquid storage tank 1 is connected to the discharge pipe 3, the top of the right end of the liquid storage tank 1 is connected to a first ventilation pipe 4, a vacuum pumping mechanism is provided on the first ventilation pipe 4, the right end of the liquid storage tank 1 is connected to a sampling pipe 5, and a sampling mechanism is provided on the sampling pipe 5. By opening the valve on the feed pipe 2, the ammonium nitrate solution is transported into the interior of the liquid storage tank 1, and then the valve on the feed pipe 2 is closed to re-seal the interior of the liquid storage tank 1. The air inside the liquid storage tank 1 is discharged through the vacuum pumping mechanism to ensure the airtightness inside the liquid storage tank 1. When it is necessary to check whether the ammonium nitrate solution inside the liquid storage tank 1 has deteriorated, the ammonium nitrate solution can be detected through the sampling mechanism, and the airtightness can also be ensured. When discharging, the valve of the discharge pipe 3 is opened.

[0021] A clamping mechanism is provided at the top of the first ventilation pipe 4. The clamping mechanism includes a clamping cylinder 6 and a fixed sleeve 10. The top of the first ventilation pipe 4 is fixedly connected to the clamping cylinder 6, the outside of the clamping cylinder 6 is threadedly connected to the fixed sleeve 10, and the inside of the fixed sleeve 10 is of a structure that is narrow at the top and wide at the bottom. The demisting net 8 is inserted into the interior of the first ventilation pipe 4 from top to bottom. First, the demisting net 8 is clamped inside the first ventilation pipe 4 through the retaining ring 9, and then the fixed sleeve 10 is tightened on the clamping cylinder 6. The fixed sleeve 10 squeezes the clamping cylinder 6 to contract and squeeze the top of the demisting net 8 to completely fix the demisting net 8 inside the first ventilation pipe 4.

[0022] The vacuum pumping mechanism includes a vacuum pump 12 and a second ventilation pipe 13. The vacuum pump 12 is fixedly installed on the outer side of the liquid storage tank 1. The input end of the vacuum pump 12 is communicated with the second ventilation pipe 13. The top end of the first ventilation pipe 4 is communicated with one end of the second ventilation pipe 13. An anti-foam net 8 is arranged inside the first ventilation pipe 4. The outer side of the anti-foam net 8 is snap-connected with the bottom end of the first ventilation pipe 4 through a retaining ring 9. The top end of the anti-foam net 8 is fixedly connected with a threaded pipe 7. One end of the second ventilation pipe 13 is communicated with a connector 11. The inner wall of the connector 11 is threadedly connected with the outer wall of the threaded pipe 7. Tighten the connector 11 at one end of the second ventilation pipe 13 on the threaded pipe 7 at the top end of the anti-foam net 8. At this time, the anti-foam net 8 and the vacuum pump 12 are mutually communicated through the second ventilation pipe 13. The vacuum pump 12 can extract the air inside the liquid storage tank 1 to empty the air and ensure the airtightness of the liquid storage tank 1.

[0023] A plurality of baffles 20 are arranged inside the liquid storage tank 1. The adjacent baffles 20 are staggered up and down. The shape of the baffle 20 is set as a semi-circular structure. During the process of extracting air, ammonium nitrate solution will be carried. The ammonium nitrate solution will collide with the staggered baffles 20 up and down and will gradually become more dispersed and smaller. When it passes through the first ventilation pipe 4, it will be intercepted and condensed into liquid droplets on the first ventilation pipe 4 and fall into the liquid storage tank 1 to automatically separate the air and the ammonium nitrate solution.

[0024] The sampling mechanism includes a push-pull rod 14, a piston 15, a spring 16 and a plunger 17. The push-pull rod 14 is slidably connected inside the sampling tube 5. One end of the push-pull rod 14 is fixedly connected with the piston 15. The spring 16 is arranged outside the push-pull rod 14. The plunger 17 is arranged at the bottom end of the sampling tube 5. If the ammonium nitrate solution deteriorates and impurities precipitate at the bottom, by pulling the push-pull rod 14 to move outward, the piston 15 is driven to move deeper into the sampling tube 5 to extract the ammonium nitrate solution at the bottom of the liquid storage tank 1 into the sampling tube 5, so that the ammonium nitrate solution enters the plunger 17. At this time, the spring 16 is in a compressed state. When the hand is released, the elastic force of the spring 16 is used to drive the push-pull rod 14 and the piston 15 to reset and re-close the sampling tube 5 and the liquid storage tank 1.

[0025] The outer wall of the piston 15 is in fit connection with the inner wall of the sampling tube 5. A sponge 19 is arranged inside the plunger 17. A threaded surface 18 is arranged at the top end of the plunger 17. The top end of the plunger 17 is threadedly connected with the bottom end of the discharge pipe 3 through the threaded surface 18. When the ammonium nitrate solution enters the plunger 17, the ammonium nitrate solution will be absorbed by the sponge 19 therein, and its impurities will be intercepted at the top of the sponge 19. After unscrewing the plunger 17 from the bottom of the sampling tube 5, people can clearly judge whether there are impurities in the ammonium nitrate solution by observing the sponge 19. Then, a new sponge 19 is stuffed into the plunger 17 and the plunger 17 is screwed back to the bottom of the sampling tube 5.

[0026] For this large horizontal ammonium nitrate solution storage tank, if the ammonium nitrate solution deteriorates and impurities precipitate at the bottom, pulling the push rod 14 to move outward drives the piston 15 to move deeper into the sampling tube 5 to extract the ammonium nitrate solution at the bottom of the storage tank 1 into the interior of the sampling tube 5, so that the ammonium nitrate solution enters the interior of the plunger 17. At this time, the spring 16 is in a compressed state. When the hand is released, the elastic force of the spring 16 drives the push rod 14 and the piston 15 to reset, and closes the sampling tube 5 and the storage tank 1 again. When the ammonium nitrate solution enters the interior of the plunger 17, the ammonium nitrate solution will be absorbed by the sponge 19 therein, and its impurities will be intercepted at the top of the sponge 19. After unscrewing the plunger 17 from the bottom of the sampling tube 5, people can clearly judge whether there are impurities in the ammonium nitrate solution by observing the sponge 19. Then, a new sponge 19 is inserted into the plunger 17, and the plunger 17 is screwed back to the bottom of the sampling tube 5.
