Technical Field

[0001] The utility model relates to the technical field of gas storage tanks, in particular to a leakage-proof chemical gas storage tank. Background Art

[0002] Gas storage tanks are steel sealed containers used to store liquids or gases. Storage tank engineering is an indispensable and important infrastructure for industries such as petroleum, chemical, grain and oil, food, fire protection, transportation, metallurgy, and national defense. With the continuous development of the storage tank industry, more and more industries and companies have used storage tanks, and more and more companies have entered the storage tank industry. Storage tanks are special equipment for storing various liquids, gas raw materials and finished products. In particular, the chemical manufacturing industry is inseparable from storage tanks of various capacities and types.

[0003] Existing chemical gas storage tanks often use valves to seal the gas storage tanks. The sealing process is time-consuming and labor-intensive, and the sealing structure is relatively simple. During use, due to improper operation by the staff, the valve turntable is not turned to the appropriate position, which will cause the tank to leak and cause a safety accident. In addition, the existing gas storage tanks cannot alarm after a leak occurs, resulting in certain limitations in the safety protection of the gas storage tanks.

[0004] To this end, we designed a leak-proof chemical gas storage tank. Utility Model Content

[0023] Reference Figure 1-Figure 5 A leak-proof chemical gas storage tank includes a gas storage tank 1, a mounting flange 2 is fixedly mounted on the gas storage tank 1, a protective pad is fixedly arranged at the bottom of the gas storage tank 1, the leak-proof device is fixedly mounted on the gas storage tank 1 through the mounting flange 2, and the protective pad at the bottom of the gas storage tank 1 keeps the gas storage tank 1 stable.

[0024] The mounting flange 2 is connected to a guide bin 3, a cavity is opened in the guide bin 3, and a plurality of airflow channels are opened in the guide bin 3 at the same time. The airflow channels are interconnected through the cavity, one side of the airflow channel is connected to the gas storage tank 1, and the other side of the airflow channel is connected to the return pipe 11.

[0025] A fixing ring 4 is fixedly installed on the guide chamber 3, and a limiting block 5 is coaxially arranged on the fixing ring 4. The limiting block 5 is provided with a protruding end, and holes are provided on the protruding end and the fixing ring 4. The limiting block 5 is rotatably connected to the fixing ring 4. The limiting block 5 is moved to an appropriate position by rotating the limiting block 5. At this time, the hole on the limiting block 5 and the hole on the fixing ring 4 are in the same axial position.

[0026] A fixing nail is inserted into the hole, circular holes are opened on both sides of the limit block 5, and insertion rods are set on both sides of the sleeve 9. The insertion rods cooperate with the circular holes. The fixing nail passes through the hole on the limit block 5 and rests against the hole on the fixing ring 4. At this time, the fixing nail fixes the fixing ring 4 and the limit block 5. The fixation of the limit block 5 performs preliminary leakage prevention treatment on the gas storage tank 1.

[0027] A sleeve 9 is sleeved on the push rod, and a rubber block 8 is connected to the push rod. A rotating valve 10 is fixedly connected to the sleeve 9. By pushing the rotating valve 10, the inner wall of the sleeve 9 squeezes the rubber block 8. The rubber block 8 is deformed by the squeezing, so that the rubber block 8 and the sleeve 9 fit closely. The rotating valve 10 is rotated to drive the sleeve 9 to rotate synchronously, thereby further increasing the friction between the rubber block 8 and the sleeve 9, and the gas storage tank 1 is again leak-proof.

[0028] The limit block 5 is coaxially mounted with a push rod, on which a plurality of flip blades 6 and a driving blade 7 are mounted. The flip blades 6 and the driving blades 7 are both located in the cavity of the guide bin 3. The airflow enters the cavity through an airflow channel on one side, driving the driving blade 7 to rotate. During the rotation process, the driving blade 7 drives the flip blade 6 to rotate synchronously.

[0029] The driving blade 7 is arranged to be inclined, and the shape design of the driving blade 7 makes it easier for the airflow to drive the driving blade 7 to rotate.

[0030] The flip blade 6 and the drive blade 7 are arranged in a circular array with the push rod as the axis. The gas storage tank 1 is equipped with a return pipe 11, which is connected to the internal cavity of the guide chamber 3. The airflow is changed in direction by the flip blade 6 and enters the return pipe 11 through the airflow channel on the other side, thereby returning to the inside of the gas storage tank 1 through the return pipe 11.

[0031] A test tube 12 is installed on the top of the gas storage tank 1, and a gas leakage alarm 13 is fixedly installed on the test tube 12. A buzzer 15 and a reset button 16 are fixedly set on the gas leakage alarm 13. A button battery for providing power, a sensitive pressure sensor and a logic circuit for generating electrical signals are installed inside the gas leakage alarm 13.

[0032] A pressure gauge 14 is fixedly provided on the air leakage alarm 13 , a buzzer 15 and a reset button 16 are located on one side of the air leakage alarm 13 , and the pressure gauge 14 is located on the other side of the air leakage alarm 13 .

[0033] The input end of the pressure gauge 14 is electrically connected to the signal end of the sensitive pressure sensor, the power input end of the buzzer 15 is electrically connected to the power end of the button battery, the electrical signal reset end of the logic circuit is electrically connected to the output end of the reset button 16, the output end of the sensitive pressure sensor is electrically connected to the input end of the logic circuit, and the control end of the buzzer 15 is electrically connected to the electrical signal output end of the logic circuit.

[0034] Furthermore, when the logic circuit receives a continuous pressure reduction signal from the pressure sensor within half an hour, an action electrical signal can be triggered at the output end, and the action electrical signal is transmitted to the buzzer 15. The buzzer 15 is activated to emit an alarm sound, and the staff can receive the alarm and know that there is a problem with the airtightness of the tank body, thereby avoiding serious consequences caused by excessive leakage of gas.

[0035] The working principle of the utility model is as follows: the sleeve 9 is pushed, the sleeve 9 squeezes the rubber block 8 and is clamped with the inner wall of the sleeve 9, and at the same time the rod is inserted into the circular hole, the fixing ring 4 and the limit block 5 are fixedly connected by the fixing nails, and the airflow enters the guide chamber 3, driving the flip blade 6 and the driving blade 7 to rotate, so that the airflow returns to the gas storage tank through the return pipe 11, thereby improving the anti-leakage effect of the gas storage tank, and the test tube 12 will detect the air pressure in the gas storage tank. When the air pressure is unstable, an alarm will be issued through the buzzer 15.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
