The cryogenic liquid transport tank with multiple layers of insulation provided by the utility model can fine-tune the temperature inside the transport tank and efficiently keep warm by arranging a middle functional layer capable of heat insulation or fine-tuning the temperature on a traditional structure of this type. In addition, by arranging a buffer portion, the structure can reduce the damage to the overall structure caused by liquid sloshing during transportation.

[0004] In the prior art, chemical liquids are often transported in chemical tanks during ship or road transportation. However, during sea or road transportation, fluctuations are inevitable, which causes the liquid inside the tank to surge. This surge will resonate with the external turbulence, thereby intensifying the vibration. This vibration may eventually cause damage to the tank. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a chemical liquid transportation surge-proof storage tank.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A chemical liquid transportation surge protection storage tank, comprising a tank body, and further comprising:

[0008] The surge protection component includes a guide rod fixedly installed inside the tank body, a grille plate is slidably installed on the surface of the guide rod, a connecting hole is provided at the bottom of the grille plate, a vent hole is provided at the top of the grille plate, a spring is sleeved and installed on the surface of the guide rod between the grille plates, the spring is connected to the grille plates on both sides, and a reinforcement cover is provided on one side of the tank body.

[0009] According to a further technical solution, a sliding hole is provided at the position where the grid plate contacts the guide rod.

[0010] According to a further technical solution, a material trough is provided on one side of the tank body, and a feed box is installed on the surface of the material trough.

[0011] According to a further technical solution, an oil pipe is butt-jointedly installed on the other side of the tank body, and an output tank is butt-jointedly installed on one side of the oil pipe.

[0012] According to a further technical solution, a friction pad is fixedly installed on the bottom of the tank body.

[0013] According to a further technical solution, a rear cover is provided on the back of the tank body.

[0014] Compared with the prior art, the utility model provides a chemical liquid transportation surge protection storage tank, which has the following beneficial effects:

[0015] Through the anti-surge assembly, the internal cavity of the entire tank is divided into different sections, and a number of guide rods are set. Multiple grid plates are slidably installed on the surface of the guide rods. The grid plates divide the chemical liquid into different sections, thereby reducing the amplitude of the surge. In addition, since surges are inevitable, we need to limit them to a controllable range. The connecting holes at the bottom of the grid plates can realize the exchange between liquids, thereby avoiding the isolation of liquids inside the tank. The air holes at the top realize the connection of gas. Once a surge occurs, the liquid pushes the grid plates to move between the guide rods, and the springs connected between the grid plates will realize the buffering of the grid plates, thereby indirectly reducing the degree of surge and bringing it within the range of safe transportation.

[0024] The surge prevention component 2 achieves the surge prevention effect during the transportation of chemical liquids by optimizing the internal structure of the tank body 1. The surge prevention component 2 includes a guide rod 3 fixedly installed inside the tank body 1, and the function of the guide rod 3 is to support and ensure the sliding of the grid plate 4. The surface of the guide rod 3 is slidably installed with a grid plate 4, and the grid plate 4 divides the structure inside the tank body 1 into different spaces, thereby reducing the probability of surges. The bottom of the grid plate 4 is provided with a connecting hole 6, and the connecting hole 6 ensures the intercommunication between the liquids, thereby achieving the integrated surge prevention effect. The top of the grid plate 4 is provided with a vent 7 for achieving the effect of gas intercommunication. The surface of the guide rod 3 between the grid plates 4 is sleeved with a spring 8, and the spring 8 is connected between the adjacent grid plates 4. Once a surge occurs, the grid plate 4 can buffer the force to the surface of the spring 8, thereby indirectly achieving the surge prevention effect. The spring 8 is connected to the grid plates 4 on both sides, and a reinforcement cover 9 is provided on one side of the tank body 1. The function of the reinforcement cover 9 is to increase the space for the gas, thereby avoiding the appearance of a bulging tank.

The feed box 11 is mounted on the surface of the trough 10 in a butt connection.

[0027] A chemical liquid transport surge protection storage tank, the other side of the tank body 1 is butt-jointed with an oil pipe 12, the oil pipe 12 and the output tank 13 are used to output and take the liquid inside the tank body 1.

[0030] Working principle:

[0031] In the actual creation process of the utility model, the following defects existing in the prior art are solved: chemical liquids in the prior art are often transported in chemical tanks during ship transportation or road transportation. However, waves are inevitably formed during sea or road transportation, which causes the liquid inside the tank to surge. This surge will resonate with the external turbulence, thereby intensifying the vibration. This vibration may eventually cause damage to the tank. Therefore, a surge protection component 2 is specifically proposed;

[0032] The surge protection component 2 mainly sets up several guide rods 3 inside the tank body 1; and several grille plates 4 are slidably installed on the surface of the guide rods 3. The grille plate 4 divides the space inside the tank body 1 into several areas, thereby directly reducing the possibility of surge. The connecting holes 6 set at the bottom of the grille plate 4 are used to achieve the connection between chemical liquids, thereby ensuring the integrity of the liquid inside the tank body 1, which is convenient for subsequent use. The vents 7 on the top realize gas exchange, thereby avoiding the problem of unstable pressure inside the tank body 1. In addition to using the grille plate 4 to divide the tank body 1, we also install springs 8 on the surface of the guide rods 3 between the grille plates 4. Once a surge occurs, the liquid will hit the grille plate 4, and the springs 8 between the grille plates 4 will pull the grille plate 4, thereby avoiding the problem of excessive surge. The surge problem is then indirectly solved.

[0033] As auxiliary components of the device, the trough 10 and the feed box 11 are used to input liquids, while the oil pipe 12 and the output tank 13 are used to take out chemical liquids, thereby ensuring the integration of the device. The friction pad 14 at the bottom can effectively prevent slipping and maintain the stability of the entire device.
