However, the valve's sealing of the drain port has the following drawbacks: if the valve is damaged or accidentally not closed tightly, there is a risk of accidental sulfuric acid leakage. Therefore, the drain port of the sulfuric acid storage tank needs to be improved. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] This utility model provides a dispensing and storage tank for sulfuric acid solution production. Please refer to [link / reference]. Figure 1-3 The tank includes a storage tank body 1, the top of which has a liquid inlet 5, a sealing plug 6 plugged in the liquid inlet 5, and a liquid outlet on the storage tank body 1. The liquid outlet includes an interface 2 integrally formed with the storage tank body 1, and a sealing mechanism is provided in the interface 2.

[0028] Under the influence of gravity, the sealing mechanism seals the interface 2 of the sulfuric acid inside the storage tank 1.

[0029] The sealing mechanism includes a support ring 10 integrally formed with the inner wall of the interface 2, a first sealing ring 8 is bonded to the support ring 10, and a sealing disc 9 is located above the first sealing ring 8.

[0030] It also includes a liquid discharge mechanism; the liquid discharge mechanism can open the sealing mechanism and discharge the sulfuric acid in the storage tank body 1.

[0031] The liquid dispensing mechanism includes a sleeve 4, a valve is installed at the bottom of the sleeve 4, and a second sealing ring 17 is bonded inside the sleeve 4. The second sealing ring 17 is fitted onto the interface 2 and clamps the interface 2.

[0032] A support rod 16 is fixedly installed on the inner wall of the sleeve 4. A first vertical support rod 15 is fixedly installed at the top of the support rod 16. A support beam 12 is fixedly installed at the top of the first vertical support rod 15. The support beam 12 is slidably connected to the interface 2. Specifically, a groove 13 is provided on the inner wall of the interface 2. Slider 14 is fixedly installed at both ends of the support beam 12. The slider 14 is slidably connected to the inner wall of the groove 13. A second vertical support rod 11 is fixedly installed at the top of the support beam 12. A hollow tube 21 is sleeved at the top of the second vertical support rod 11. A sealing disc 9 is fixedly connected to the top of the hollow tube 21. Both the support rod 16 and the support beam 12 are rod-shaped, while the sealing disc 9 is disc-shaped.

[0033] like Figure 3 As shown, at this time, under the gravity of sulfuric acid, sealing disc 9 and hollow tube 21 inside the storage tank body 1, sealing disc 9 is pressed against the first sealing ring 8, thereby achieving the sealing of interface 2.

[0034] A lifting mechanism is installed between interface 2 and sleeve 4, which can drive sleeve 4 to move up and down. The lifting mechanism includes a first support block 22 integrally formed on the outer wall of interface 2 and a second support block 41 integrally formed on the outer wall of sleeve 4. A threaded pin 7 is threadedly connected to the first support block 22. The threaded pin 7 passes through a through hole on the second support block 41, and a limit plate is welded to the bottom of the threaded pin 7.

[0035] In practical use:

[0036] Not only does the valve seal the drain outlet, but under the gravity of the sulfuric acid, the sealing disc 9, and the hollow tube 21 inside the tank body 1, the sealing disc 9 is pressed against the first sealing ring 8, thereby achieving the sealing of the interface 2.

[0037] When sulfuric acid needs to be discharged, the threaded pin 7 is turned to drive the sleeve 4 to rise. The support rod 16, the first vertical support rod 15, the support beam 12 and the second vertical support rod 11 move upward to drive the sealing disc 9 to rise. Thus, the sealing disc 9 enters the cavity at the top of the interface 2, and then the valve on the sleeve 4 is opened to discharge the sulfuric acid.

[0038] Example 2:

[0039] See attached document Figure 4 Unlike Embodiment 1, the outer wall of the interface 2 has an integral first support block 22, and the outer wall of the sleeve 4 has an integral second support block 41.

[0040] An electric push rod 18 is installed between the first support block 22 and the second support block 41. Specifically, a first support connecting seat 19 is welded to the first support block 22, and the electric push rod 18 is inserted into the inner wall of the first support connecting seat 19. The electric push rod 18 and the first support connecting seat 19 are fixed together by bolts. A second support connecting seat 20 is welded to the second support block 41, and the electric push rod 18 is inserted into the inner wall of the second support connecting seat 20. The electric push rod 18 and the second support connecting seat 20 are fixed together by bolts.

[0041] In practical use:

[0042] Not only does the valve seal the drain outlet, but under the gravity of the sulfuric acid, the sealing disc 9, and the hollow tube 21 inside the tank body 1, the sealing disc 9 is pressed against the first sealing ring 8, thereby achieving the sealing of the interface 2.

[0043] When sulfuric acid needs to be discharged, the electric push rod 18 retracts, driving the sleeve 4 to rise. The support rod 16, the first vertical support rod 15, the support beam 12, and the second vertical support rod 11 move upward, driving the sealing disc 9 to rise. Thus, the sealing disc 9 enters the cavity at the top of the interface 2, and the valve on the sleeve 4 is opened, thereby discharging the sulfuric acid. Not only does the valve seal the discharge port, but under the gravity of the sulfuric acid, the sealing disc 9, and the hollow tube 21 inside the storage tank body 1, the sealing disc 9 is pressed against the first sealing ring 8, thereby achieving the seal of the interface 2.

[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
