[0002] Currently, when unloading concentrated sulfuric acid, it is unloaded directly into a large storage tank in the workshop through a pipeline. At the end of unloading, some of the concentrated sulfuric acid in the pipeline will flow onto the ground, causing smoke. To address this problem, the current improvement measure is to install a buffer tank before the large storage tank. The concentrated sulfuric acid from the truck is first unloaded into the buffer tank, and then flows from the buffer tank to the large storage tank. In this way, the excess concentrated sulfuric acid in the pipeline is stored in the buffer tank. However, the existing buffer tank has the following disadvantages when in use: First, when pouring concentrated sulfuric acid, the liquid fluctuates greatly, causing the liquid level meter installed inside to fluctuate greatly, resulting in inaccurate measurement; Second, during storage, the gas inside the tank cannot be automatically discharged.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Buffer tanks for concentrated sulfuric acid loading and unloading are specialized equipment used for temporary storage and buffering during the loading and unloading process. They reduce the risk of volatilization and leakage of concentrated sulfuric acid during loading and unloading, minimizing hazards to the environment and operators. During the transfer of concentrated sulfuric acid, buffer tanks can regulate the flow rate, ensuring a smoother loading and unloading process and avoiding large pressure fluctuations. Buffer tanks are typically equipped with safety valves to prevent overpressure caused by temperature fluctuations or other factors. Buffer tanks provide a temporary storage area, making the dumping and transfer of concentrated sulfuric acid more convenient and reducing the risk of direct contact with hazardous chemicals.
[0024] Based on the technical defects of the existing technology such as inaccurate liquid level measurement and inability to automatically discharge gas, please refer to Figure 1-Figure 5 The utility model provides a buffer tank for safe concentrated sulfuric acid loading and unloading. Since the top of the slow flow cover 3 is conical, the liquid can flow around along the top of the slow flow cover 3, and then flow downward close to the outer wall of the slow flow cover 3, which can reduce the fluctuation amplitude of the liquid inside the tank body 1, thereby improving the measurement accuracy of the liquid level meter 6 and realizing automatic exhaust. The buffer tank includes a tank body 1, a slow flow cover 3 is fixedly arranged in the tank body 1, the top of the slow flow cover 3 is a convex cone, a liquid inlet pipe 2 is arranged above the slow flow cover 3, one end of the liquid inlet pipe 2 extends to the outside of the tank body 1, and a skirt is provided at the bottom of the slow flow cover 3. There are multiple lower connecting holes 301 on it, multiple supporting blocks 4 are fixed to the bottom of the skirt, upper connecting holes 302 are provided on the outer wall of the slow flow cover 3 near the top, a liquid level gauge 6 is also installed on the tank body 1, an exhaust assembly 9 is fixed on the top of the tank body 1, and a liquid outlet pipe 8 is fixed on the bottom of the tank body 1; concentrated sulfuric acid enters the tank body 1 through the liquid inlet pipe 2, and under the action of the slow flow cover 3, the liquid can flow around along the top of the slow flow cover 3, and then flow downward close to the outer wall of the slow flow cover 3, and finally, under the action of the lower connecting holes 301 and the upper connecting holes 302, the balance of the liquid inside and outside the slow flow cover 3 is achieved.
[0025] To solve the problem of internal exhaust in the buffer tank when pouring concentrated sulfuric acid, please refer to Figure 5The exhaust assembly 9 includes an exhaust pipe 901 fixed to the top of the tank body 1, and a piston 902 is movably arranged in the exhaust pipe 901. The piston 902 is fixed to the bottom of the piston rod 903, and the piston rod 903 is movably connected to the fixed cover 904. The fixed cover 904 is threadedly connected to the top of the exhaust pipe 901. A spring 905 connected between the piston 902 and the fixed cover 904 is sleeved on the outer wall of the piston rod 903; as the liquid in the tank body 1 increases, the gas can push the piston 902 and make it move upward. After the exhaust hole 9021 inside the piston 902 is aligned with the through hole on the exhaust pipe 901, the gas inside the tank body 1 can be automatically discharged to the outside of the tank body 1.
[0026] To ensure the discharge of gas, an exhaust hole 9021 is provided in the piston 902, and the exhaust hole 9021 is adapted to the through hole opened on the outer wall of the exhaust pipe 901; when the piston 902 moves upward, the exhaust hole 9021 also moves upward. When one end of the exhaust hole 9021 is aligned with the through hole, the inside and outside of the tank body 1 can be connected, thereby facilitating exhaust.
[0027] When the liquid flows out from one end of the liquid inlet pipe 2, it is easy to splash around, which will affect the liquid fluctuation. To solve this problem, a baffle 11 is installed on the outer wall of the liquid inlet pipe 2 near the slow flow cover 3; the baffle 11 blocks the excess splashing liquid, thereby ensuring that the liquid can flow down along the slow flow cover 3.
[0028] In order to measure the liquid in the tank body 1, the liquid level meter 6 passes through the installation hole opened on the slow flow cover 3 and extends to the inside of the slow flow cover 3, and a blocking bar 7 is provided on the outside of the installation hole; in this way, the liquid level meter 6 can realize the liquid level detection function inside the tank body 1.
[0029] In order to improve the installation strength of the slow flow cover 3, a pad 5 is fixed between the tank body 1 and the slow flow cover 3; the pad 5 supports the bottom of the slow flow cover 3, so that the slow flow cover 3 is installed more firmly in the tank body 1 and also facilitates the complete discharge of the liquid.
[0030] In order to facilitate observation of the interior of the tank body 1 , a viewing window 10 is embedded on the outer wall of the tank body 1 .
[0031] It can be seen from the above embodiment that concentrated sulfuric acid enters the tank body 1 through the liquid inlet pipe 2. Under the action of the slow flow cover 3, the liquid can flow around along the top of the slow flow cover 3, and then flow downward close to the outer wall of the slow flow cover 3. Finally, under the action of the lower connecting hole 301 and the upper connecting hole 302, the balance of the liquid inside and outside the slow flow cover 3 is achieved. As the liquid in the tank body 1 increases, the gas can push the piston 902 and move it upward. After the exhaust hole 9021 inside the piston 902 is aligned with the through hole on the exhaust pipe 901, the gas inside the tank body 1 can be automatically discharged to the outside of the tank body 1. When the liquid is poured in, the spring 905 pushes the piston 902 to reset, thereby blocking the through hole on the exhaust pipe 901.
