Description

Technical Field

[0001] This utility model relates to the field of emulsion explosives technology, and in particular to a leak-proof component for feeding aqueous storage tanks. Background Technology

[0002] There is a serious nitrate leakage at the feed inlet of the aqueous phase storage tank in the pharmaceutical workshop. During the production process, severe crystallization occurs around the cover, which is not conducive to on-site cleaning and poses certain safety hazards. The apparent cause of this nitrate leakage is that the cover of the aqueous phase storage tank feed inlet is not tightly positioned with the tank body during the feeding and purging process, resulting in the leakage of some pharmaceutical material. The root cause is that the steel cover is corroded and deformed over a long period of time, and the assembly gap widens, leading to material leakage. To solve this problem, a leak-proof component for the aqueous phase storage tank feed inlet was designed. Utility Model Content

[0013] The beneficial effects of this utility model are as follows: using a quartz glass kit as the main sealing structure, and then squeezing from the upper and lower sides of the feed inlet through the deformation pressure of the sealing gasket and sealing ring, respectively, to achieve the positioning of the leak-proof component and the sealing of the feed inlet.

[0023] Reference Figure 1-8 The water phase storage tank feed leak prevention component includes a top cover 1, a quartz glass kit 2 and a protective sleeve 3. A sealing gasket 4 is fixed on the lower surface of the protective sleeve 3. The quartz glass kit 2 is fitted with the feed inlet of the water phase storage tank. The part of the quartz glass kit 2 outside the feed inlet is protected by adding the protective sleeve 3.

[0024] The quartz glass kit 2 includes an assembly end 201 and a fitting end 202. The surface of the fitting end 202 is provided with a fitting ring groove 203 and a sealing ring groove 204. A sealing ring 205 is fitted inside the sealing ring groove 204.

[0025] The protective sleeve 3 has a fitting groove 301 inside, and a sealing sleeve 302 is fitted inside the fitting groove 301. The quartz glass kit 2 is fitted inside the sealing sleeve 302, and the fitting ring groove 203 on the surface of the sealing sleeve 302 fits and connects with the sealing sleeve 302.

[0026] The surface of the sealing gasket 4 is provided with multiple mounting protrusions 401, and multiple mounting holes are opened inside the mounting protrusions 401. A sealing post 402 is interference-fitted into the mounting hole.

[0027] The sealing gasket 4, sealing ring 205, and sealing sleeve 302 are all made of polytetrafluoroethylene, which has a certain elasticity and corrosion resistance. After the entire leak-proof assembly is assembled with the inlet, the sealing gasket 4 and sealing ring 205 are deformed and squeezed from the upper and lower sides of the inlet to position the leak-proof assembly. The specific squeezing pressure can be achieved by replacing the sealing gasket 4 with one of different thickness and the sealing ring 205 with one of different diameter.

[0028] Multiple first screws 5 are threadedly installed between the top cover 1 and the quartz glass kit 2. Multiple threaded holes are opened on the surface of the top cover 1 and the surface of the quartz glass kit 2.

[0029] Multiple second screws 6 are threadedly installed between the top cover 1 and the protective sleeve 3. Multiple threaded holes are opened on the side wall of the top cover 1 and the side wall of the protective sleeve 3.

[0030] Multiple third screws 7 are threadedly installed between the sealing gasket 4 and the protective sleeve 3. The third screws 7 are assembled in the assembly hole, and the top of the assembly hole has a through hole. The lower surface of the protective sleeve 3 has a fitting hole, and the top of the fitting hole has a threaded hole.

[0031] The sealing gasket 4 is fitted around the bottom of the sealing ring 205.

[0032] Both the top cover 1 and the quartz glass kit 2 have through-holes 8 for pipe assembly.

[0033] When using this device, first, the feed pipe is passed through the pipe assembly hole 8 of the top cover 1 and the quartz glass kit 2, and the feed pipe is fixed in the pipe assembly hole 8. Then, the entire structure is fitted into the feed inlet of the aqueous phase storage tank. After fitting, the sealing gasket 4 is pressed against the area around the feed inlet and deformed to achieve a seal and prevent leakage. The sealing ring 205 is fitted against the bottom of the feed inlet and presses upward against the area of ​​the inner wall of the aqueous phase storage tank near the feed inlet. The sealing gasket 4 and the sealing ring 205 work together to press the two plates of the feed inlet to achieve sealing and positioning.
