[0001] The utility model relates to the technical field of storage tanks, in particular to an anti-overflow sulfuric acid storage tank with self-adjusting liquid level. Background Technique

[0002] In many industries such as chemical engineering and metallurgy, sulfuric acid, as an important basic chemical, its storage and management are crucial.

[0003] Traditional sulfuric acid storage tanks often adopt a liquid level control method with a fixed structure. This method is not only cumbersome to operate, but also difficult to achieve precise liquid level adjustment, easily leading to the overflow of sulfuric acid, which not only causes waste of resources, but also may pose a threat to the environment and personnel safety. At the same time, traditional storage tanks also have deficiencies in liquid level monitoring and management. It is difficult for operators to intuitively and accurately understand the liquid level situation in the tank, further increasing the risk of overflow. In view of this, we propose an anti-overflow sulfuric acid storage tank with self-adjusting liquid level. Content of the Utility Model

A drain pipe 16 is installed on one side of the outer wall of the tank body 1 near the bottom, and a second solenoid valve 17 is installed on the drain pipe 16. By arranging a liquid filling pipe 13 and a feeding port at the top of the tank body 1, and arranging a telescopic sealing plug assembly below the feeding port, using the hollow sealing ball 19, the hollow floating ball 114 and the adjusting mechanism between them, the position of the sealing plug assembly is automatically adjusted according to the height of the liquid level, so as to control the addition of sulfuric acid and prevent overflow. At the same time, the drain pipe 16 and the solenoid valve installed on one side of the outer wall of the tank body 1 near the bottom facilitate the discharge and control of sulfuric acid

[0025] It should be added that a flange 14 is installed on the liquid filling pipe 13

[0026] As a preference of this embodiment, an observation window 10 is provided on the outer wall of the tank body 1, and a scale line 11 is provided on the observation window 10. By providing an observation window 10 and a scale line 11 on the outer wall of the tank body 1, operators can directly observe the liquid level height in the tank body 1, which is convenient for monitoring and management

[0027] Preferably, in this embodiment, a stabilizing seat 12 is fixedly installed at the top of the tank body 1, and the liquid filling pipe 13 passes through the stabilizing seat 12 and is fixedly connected thereto. By fixedly installing the stabilizing seat 12 at the top of the tank body 1 and passing the liquid filling pipe 13 through the stabilizing seat 12 and fixedly connecting them, the stability and firmness of the liquid filling pipe 13 are enhanced, and the safety of use is improved.

[0028] Preferably, in this embodiment, a leg 2 is fixedly connected to each of the four corners at the bottom of the tank body 1. A leg 2 is fixedly connected to each of the four corners at the bottom of the tank body 1, enabling the storage tank to be stably placed on the ground and improving the overall stability and load-bearing capacity.

[0029] Preferably, in this embodiment, the adjusting mechanism includes a servo motor 115 fixed inside the hollow sealed ball 19. A lead screw 116 is coaxially fixed to the output shaft of the servo motor 115. A driving plate 117 is threadedly connected to the lead screw 116. Two connecting rods 118 are symmetrically and fixedly connected to the bottom of the driving plate 117, and the bottoms of the connecting rods 118 are fixed to the hollow floating ball 114. The specific structure of the adjusting mechanism is described in detail, including components such as the servo motor 115, lead screw 116, driving plate 117, and connecting rod 118. Through the coordinated action of these components, the precise adjustment of the distance between the hollow sealed ball 19 and the hollow floating ball 114 is achieved, further improving the accuracy and reliability of liquid level control.

[0030] Preferably, in this embodiment, the hollow sealed ball 19 is hemispherical, and a corrugated pipe 113 is fixedly installed between the bottom of the hollow sealed ball 19 and the top of the hollow floating ball 114. The adjusting mechanism is located inside the corrugated pipe 113. The hollow sealed ball 19 is designed to be hemispherical and fixedly installed with the corrugated pipe 113 between its bottom and the top of the hollow floating ball 114. This design not only ensures the sealing performance but also allows the hollow sealed ball 19 to move up and down within a certain range. At the same time, the corrugated pipe 113 protects the adjusting mechanism located inside it and extends the service life.

[0031] Preferably, in this embodiment, two extension plates 112 are symmetrically and integrally formed on the hollow sealed ball 19. Two guide rods 110 are symmetrically and fixedly installed on the inner wall of the top of the tank body 1. The two guide rods 110 respectively pass through the two extension plates 112, and a anti-falling block 111 is fixedly connected to the bottom of each guide rod 110. Two extension plates 112 are symmetrically and integrally formed on the hollow sealed ball 19 and connected to the inner wall of the top of the tank body 1 through the guide rods 110. This design not only limits the movement range of the hollow sealed ball 19 but also ensures its movement stability, preventing deviation and tilt.

[0032] Preferably, in this embodiment, a pressure sensor 190 is embedded and installed at the center of the top of the hollow sealing ball 19. When the pressure sensor 190 embedded and installed at the center of the top of the hollow sealing ball 19 detects that the pressure exceeds a certain threshold, the first solenoid valve 15 is closed to stop adding sulfuric acid into the tank body 1.

[0033] When the sulfuric acid storage tank with self-regulating liquid level and anti-overflow and leakage prevention of the present utility model is in use:

[0034] Liquid adding process: When it is necessary to add sulfuric acid into the storage tank, the operator first opens the first solenoid valve 15 on the liquid adding pipe 13, and the sulfuric acid enters the tank body 1 through the liquid adding pipe 13. When the sulfuric acid enters the tank body 1, it will push the hollow floating ball 114 to move upward. Since the hollow floating ball 114 and the hollow sealing ball 19 are connected through an adjusting mechanism, the hollow sealing ball 19 will also move upward accordingly. During the upward movement of the hollow sealing ball 19, it will gradually close the feeding port, thereby controlling the adding speed of sulfuric acid and preventing overflow and leakage.

[0035] Liquid level adjustment: The servo motor 115 in the adjusting mechanism will automatically adjust the distance between the hollow sealing ball 19 and the hollow floating ball 114 according to the height of the liquid level. When the liquid level rises, it will drive the entire sealing plug assembly to move upward through the hollow floating ball 114 until the feeding port is blocked. However, the longer the length of the sealing plug assembly, the faster the hollow sealing ball 19 will contact the feeding port as the liquid level rises, and then the feeding port will be blocked. At this time, the liquid level in the tank body 1 is lower, and on the contrary, it is higher.

[0036] Liquid level observation and discharge: The operator can directly observe the height of the liquid level in the tank body 1 through the observation window 10 and the scale line 11 on the outer wall of the tank body 1, which is convenient for monitoring and management. When it is necessary to discharge sulfuric acid, the operator can open the second solenoid valve 17 on the liquid discharge pipe 16, and the sulfuric acid is discharged through the liquid discharge pipe 16.

[0037] Safety protection: A pressure sensor 190 is embedded and installed at the center of the top of the hollow sealing ball 19. When the pressure in the tank body 1 exceeds a certain threshold, the pressure sensor 190 will send a signal to close the first solenoid valve 15 to stop adding sulfuric acid into the tank body 1 to prevent overflow or safety accidents caused by excessive pressure.

[0038] In summary, the sulfuric acid storage tank with self-regulating liquid level and anti-overflow and leakage prevention of the present utility model realizes the safe, efficient storage and management of sulfuric acid through precise liquid level control and safety protection measures.
