Description

Technical Field

[0001] The utility model relates to the technical field of hydrochloric acid storage tanks, in particular to an automatic exhaust device for hydrochloric acid storage tanks. Background Art

[0002] A hydrochloric acid storage tank is a container used to store hydrochloric acid (hydrogen chloride solution). Hydrochloric acid is a strong acid, a colorless liquid with a pungent odor, widely used in the chemical, pharmaceutical, metal processing and other industries; the tank is usually made of corrosion-resistant materials to ensure safety and prevent leakage.

[0003] In real life, during the storage of hydrochloric acid solution, temperature changes or the filling and discharge of liquid may cause the gas pressure in the hydrochloric acid storage tank to increase. When the gas pressure in the hydrochloric acid storage tank exceeds the set value, if the hydrochloric acid storage tank is not depressurized in time, the hydrochloric acid storage tank will deform, rupture or explode. Excessive gas pressure can easily cause the seal of the hydrochloric acid storage tank to fail, increasing the risk of hydrochloric acid gas leakage. The leaked hydrochloric acid gas is highly irritating and can cause symptoms such as coughing, sore throat, and difficulty breathing after inhalation, which endangers people's health. Therefore, we propose an automatic exhaust device for hydrochloric acid storage tanks to solve the above problems. Utility Model Content

[0009] Preferably, the sealing ring on the outer side wall of the connecting rod is sealed against the inner wall of the barrel cavity; the sealing ring on the outer side wall of the connecting rod can prevent the hydrochloric acid gas from entering the upper position in the barrel cavity and then leaking out.

[0010] Preferably, the elastic connection mechanism includes a lifting block and a spring, and the lifting block is movably installed in the cylindrical cavity and multiple side grooves. The bottom side of the lifting block is fixedly connected to the top end of the connecting rod, and one end of the spring is fixedly installed on the top side of the lifting block, and the other end of the spring is fixedly installed on the top inner wall of the cylindrical cavity; when the hydrochloric acid gas pressure in the hydrochloric acid storage tank body reaches a certain amount, the air pressure in the hydrochloric acid storage tank body pushes the connecting rod and the lifting block upward, and at this time the spring is subjected to force to produce deformation and compression.

[0011] Preferably, one end of a push rod is fixedly installed on the top side of the lifting block, and the top end of the push rod extends to the outside of the exhaust pipe and is fixedly provided with a red marked protrusion; during the exhaust process of hydrochloric acid gas, the red marked protrusion on the top end of the push rod is pushed out of the exhaust pipe, which is convenient for personnel to observe that the hydrochloric acid storage tank body is undergoing automatic exhaust operation at this time.

The automatic exhaust device for hydrochloric acid storage tanks, when the hydrochloric acid gas pressure in the hydrochloric acid storage tank body reaches a certain amount, the gas pressure in the hydrochloric acid storage tank body pushes the connecting rod and the lifting block to move upward, and the spring is deformed and compressed under force. When the flow channel in the connecting rod is connected to the acid-resistant gas pipeline, the hydrochloric acid storage tank body is automatically exhausted and pressure relieved, avoiding deformation, rupture or explosion of the hydrochloric acid storage tank body due to untimely pressure relief, and reducing the risk of hydrochloric acid gas leakage in the hydrochloric acid storage tank body.

[0014] 2. The automatic exhaust device for the hydrochloric acid storage tank, the hydrochloric acid gas automatically exhausted and depressurized in the hydrochloric acid storage tank body is transported to the alkaline solution stored in the alkaline solution neutralization tank through the flow channel and the acid-resistant gas pipeline. The alkaline solution in the alkaline solution neutralization tank neutralizes the hydrochloric acid gas transported to the alkaline solution neutralization tank to generate harmless salt and water, thereby preventing the automatically exhausted hydrochloric acid gas from being directly inhaled by people and causing symptoms such as coughing, sore throat, and difficulty breathing, thereby ensuring the health of people.

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.

[0021] Example: Refer to Figure 1-4 , an automatic exhaust device for a hydrochloric acid storage tank, comprising a base 1, a hydrochloric acid storage tank body 2 and an alkaline solution neutralization tank 3 are respectively provided on the top side of the base 1, a storage chamber 4 is provided in the hydrochloric acid storage tank body 2, an exhaust pipe 5 is fixedly provided on the top of the hydrochloric acid storage tank body 2, a cylinder cavity 6 is provided in the exhaust pipe 5, a bottom opening 7 is provided at the bottom end of the exhaust pipe 5, a connecting rod 8 is movably installed in the cylinder cavity 6 in the exhaust pipe 5, a flow channel 9 is provided in the connecting rod 8, a sealing ring 10 is provided on the outer wall of the connecting rod 8, a plurality of side grooves 11 are provided on the inner wall of the cylinder cavity 6, an elastic connection mechanism for the connecting rod 8 is provided in the cylinder cavity 6 and the plurality of side grooves 11, and an acid-resistant gas pipeline 14 is provided between the exhaust pipe 5 and the alkaline solution neutralization tank 3.

[0022] Furthermore, the cylinder cavity 6 in the exhaust cylinder 5 is connected to the storage cavity 4 in the hydrochloric acid storage tank body 2 through the bottom opening 7.

[0023] Furthermore, the cross-section of the flow channel 9 in the connecting rod 8 is set in an L-shaped structure, and the flow channel 9 is adapted to the acid-resistant gas pipeline 14; when the flow channel 9 in the connecting rod 8 is connected to the acid-resistant gas pipeline 14, automatic exhaust and pressure relief are achieved in the hydrochloric acid storage tank body 2.

[0024] Specifically, the sealing ring 10 on the outer wall of the connecting rod 8 is sealed against the inner wall of the barrel cavity 6 ; the sealing ring 10 on the outer wall of the connecting rod 8 can prevent the hydrochloric acid gas from entering the upper position of the barrel cavity 6 and then leaking out.

[0025] Specifically, the elastic connection mechanism includes a lifting block 12 and a spring 13. The lifting block 12 is movably installed in the cylindrical cavity 6 and multiple side grooves 11. The bottom side of the lifting block 12 is fixedly connected to the top of the connecting rod 8. One end of the spring 13 is fixedly installed on the top side of the lifting block 12, and the other end of the spring 13 is fixedly installed on the inner wall of the top side of the cylindrical cavity 6; when the hydrochloric acid gas pressure in the hydrochloric acid storage tank body 2 reaches a certain amount, the air pressure in the hydrochloric acid storage tank body 2 pushes the connecting rod 8 and the lifting block 12 to move upward, and at this time the spring 13 is subjected to force to produce deformation and compression.

[0026] Specifically, one end of a push rod 15 is fixedly installed on the top side of the lifting block 12, and the top end of the push rod 15 passes through the outside of the exhaust pipe 5 and is fixedly provided with a red marked protrusion 16; during the exhaust process of the hydrochloric acid gas, the red marked protrusion 16 on the top end of the push rod 15 is pushed out of the exhaust pipe 5, which makes it easy for personnel to observe that the hydrochloric acid storage tank body 2 is undergoing automatic exhaust operation at this time.

[0027] During use: hydrochloric acid is sealed and stored through the hydrochloric acid storage tank body 2. When the temperature in the storage chamber 4 in the hydrochloric acid storage tank body 2 changes or the hydrochloric acid solution in the hydrochloric acid storage tank body 2 is filled or discharged, the hydrochloric acid gas pressure in the hydrochloric acid storage tank body 2 will increase. When the hydrochloric acid gas pressure in the hydrochloric acid storage tank body 2 reaches a certain amount, the air pressure in the hydrochloric acid storage tank body 2 pushes the connecting rod 8 and the lifting block 12 to move upward. The sealing ring 10 on the outer wall of the connecting rod 8 can prevent the hydrochloric acid gas from entering the upper position in the cylinder cavity 6 and leaking out. At this time, the spring 13 is deformed and compressed by the force, and the red marked protrusion 16 on the top of the push rod 15 is pushed out of the exhaust pipe 5, so that personnel can observe that the hydrochloric acid storage tank body 2 is undergoing automatic exhaust operation at this time. Until the flow channel 9 in the connecting rod 8 is connected with the acid-resistant gas pipeline 14, the hydrochloric acid storage tank body 2 is automatically exhausted and depressurized, thereby avoiding deformation, rupture or explosion of the hydrochloric acid storage tank body 2 due to untimely pressure relief, and reducing the risk of hydrochloric acid gas leakage in the hydrochloric acid storage tank body 2; the hydrochloric acid gas automatically exhausted and depressurized in the hydrochloric acid storage tank body 2 is transported to the alkaline solution stored in the alkaline solution neutralization tank 3 through the flow channel 9 and the acid-resistant gas pipeline 14, and the alkaline solution in the alkaline solution neutralization tank 3 is used to neutralize the hydrochloric acid gas transported to the alkaline solution neutralization tank 3 to generate harmless salt and water, thereby avoiding the automatically exhausted hydrochloric acid gas from being directly inhaled by people and causing symptoms such as coughing, sore throat, and difficulty breathing, thereby ensuring the health of people.
