Description

Technical Field

[0001] The utility model relates to the technical field of liquid ammonia storage tanks, in particular to a safe liquid ammonia storage tank. Background Art

[0002] Liquid ammonia, also known as anhydrous ammonia, is a colorless liquid with a strong pungent odor. It is a raw material widely used in industry and is mostly stored in pressure-resistant steel tanks or steel tanks during transportation.

[0003] Since liquid ammonia is obtained by pressurizing or cooling ammonia gas, the molecules in the liquid ammonia are very easy to volatilize when the temperature rises. As a result, when transporting liquid ammonia, the transport tank is not cooled down in time, causing the ammonia gas inside to volatilize, making the pressure inside the transport tank increase, which may cause an explosion, increasing the safety hazard. In view of this, we propose a safe liquid ammonia storage tank. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art, meet practical needs, and provide a safe liquid ammonia storage tank to solve the technical problem that the molecules in the current liquid ammonia are very easy to volatilize when the temperature rises, resulting in the volatilization of the internal ammonia gas due to the failure to cool down the transport tank in time during the transportation of liquid ammonia, which increases the pressure in the transport tank and may cause an explosion, thereby increasing the potential safety hazard.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a safe liquid ammonia storage tank, including a storage tank body, a feed port is provided on the top of the storage tank body, a cooling structure is provided on the side of the storage tank body, and two sets of legs are provided at the bottom of the storage tank body;

[0006] The cooling structure includes an interlayer, which is arranged inside the storage tank body. A support frame is arranged inside the interlayer. The support frame is connected to the storage tank body through a connecting rod. A transmission pipe is arranged inside the support frame. The upper opening of the transmission pipe is connected to a liquid outlet pipe. The bottom of the liquid outlet pipe is connected to a water pump. The lower end of the water pump is connected to a cooling box. The bottom of the cooling box is provided with a solenoid valve, and the lower end of the solenoid valve is connected to a liquid inlet pipe.

[0007] Preferably, the support frame and the transmission tube are both spiral-shaped, and the transmission tube is matched and engaged inside the support frame.

[0008] Preferably, the support frame is fixedly connected to the storage tank body via a connecting rod, and the interlayer and the storage tank body are integrally formed.

[0009] Preferably, the liquid inlet pipe is connected to the liquid outlet pipe through a transmission pipe, and the transmission pipe is evenly surrounded inside the storage tank body.

[0010] Preferably, the supporting leg comprises a limiting rod, the limiting rod is fixed to the bottom of the storage tank body, the bottom of the limiting rod is connected to a damper, and the bottom of the damper is connected to a bottom rod.

[0011] Preferably, the limiting rods form a buffer structure with the bottom rod through a damper, and the limiting rods are evenly distributed at the bottom of the storage tank body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model opens the solenoid valve to effectively allow the cold water inside the cooling box to flow to the liquid inlet pipe, and then flows into the transmission pipe through the liquid inlet pipe. Since the transmission pipe is evenly surrounded by the storage tank body, the storage tank body can be evenly cooled, effectively preventing the volatilization of liquid ammonia inside the storage tank body, thereby preventing the pressure inside the storage tank body from increasing and improving safety.

The support frame 302 is connected to the storage tank body 1 through a connecting rod 303. The support frame 302 is fixedly connected to the storage tank body 1 through the connecting rod 303. The interlayer 301 and the storage tank body 1 are integrally formed. A transmission pipe 304 is arranged inside the support frame 302. The support frame 302 and the transmission pipe 304 are both spiral-shaped. The tube 304 is matched and snapped into the inside of the support frame 302, and the upper opening of the transmission tube 304 is connected to a liquid outlet pipe 305, the bottom of the liquid outlet pipe 305 is connected to a water pump 306, the lower end of the water pump 306 is connected to a cooling box 307, and a solenoid valve 308 is provided at the bottom of the cooling box 307, and the lower end of the solenoid valve 308 is connected to a liquid inlet pipe 309. It is worth mentioning that the liquid inlet pipe 309 is connected to the liquid outlet pipe 305 through the transmission tube 304, and the transmission tube 304 is evenly surrounded by the inside of the storage tank body 1. The utility model opens the solenoid valve 308 to effectively allow the cold water in the cooling box 307 to flow to the liquid inlet pipe 309, and flows into the transmission pipe 304 through the liquid inlet pipe 309. Since the transmission pipe 304 evenly surrounds the storage tank body 1, the storage tank body 1 can be evenly cooled, and the volatilization of liquid ammonia in the storage tank body 1 is effectively avoided, thereby avoiding the increase of the internal pressure of the storage tank body 1 and improving the safety. The water passing through the transmission pipe 304 flows back to the cooling box 307 through the liquid outlet pipe 305 and is re-cooled in the cooling box 307, realizing the recycling of water resources.

[0025] In the present invention, the support frame 302 effectively limits the position of the transmission tube 304, reduces the shaking and deviation of the transmission tube 304 during transportation, and improves the placement stability of the transmission tube 304. At the same time, the effective support of the support frame 302 can reduce the stress deformation at the end of the transmission tube 304.

In the utility model, the placement stability of the storage tank body 1 is effectively increased by the damper 402, and the vibration of the storage tank body 1 during transportation is reduced, thereby increasing the storage safety of the liquid ammonia inside the storage tank body 1.

[0027] Working principle: The placement stability of the storage tank body 1 is increased by the damper 402, and the vibration of the storage tank body 1 during transportation is reduced. Then, the solenoid valve 308 is opened to allow the cold water in the cooling box 307 to flow to the liquid inlet pipe 309, and flow into the transmission pipe 304 through the liquid inlet pipe 309. Since the transmission pipe 304 is evenly surrounded by the storage tank body 1, the storage tank body 1 can be evenly cooled to avoid the volatilization of liquid ammonia in the storage tank body 1, thereby avoiding the increase of the internal pressure of the storage tank body 1, improving safety, and supporting The support frame 302 provides limited support for the transmission pipe 304 to reduce the shaking and deviation of the transmission pipe 304 during transportation. At the same time, the support of the support frame 302 can reduce the stress deformation at the end of the transmission pipe 304. The water passing through the transmission pipe 304 flows back to the cooling box 307 through the liquid outlet pipe 305 and is re-cooled inside the cooling box 307, realizing the recycling of water resources.
