Description

Technical Field

[0001] The utility model relates to the technical field of pressure tanks, in particular to a pressure tank for filling with triple-proof paint without opening the cover. Background Art

[0002] Conformal coating has good high and low temperature resistance; after curing, it forms a transparent protective film with excellent insulation, moisture-proof, leakage-proof, shock-proof, dust-proof, corrosion-proof, anti-aging, and corona-resistant properties. In the production and processing of conformal coating, a pressure tank is required. However, when adding the conformal coating concentrate to the pressure tank, the tank cover at the top of the pressure tank must be opened to add the conformal coating concentrate to the inside of the pressure tank. This wastes time and affects the production efficiency of the conformal coating. It is also complicated to operate and labor-intensive. Utility Model Content

When the conformal coating concentrate is injected into the pressure tank, the conformal coating concentrate is injected into the liquid adding filter box 5 through the liquid adding pipe 7, and the filter assembly 6 inside the filling filter mechanism 4 can filter the conformal coating concentrate, thereby preventing impurities from being injected into the pressure tank body 1. The conformal coating concentrate can be injected into the pressure tank body 1 without opening the tank cover 2, thereby improving the production efficiency of the conformal coating and reducing the labor intensity of the staff. The setting of the pressure limiting valve 3 can discharge gas to the outside when the internal pressure of the pressure tank body 1 exceeds the set value, thereby ensuring the pressure inside the pressure tank body 1.

[0023] Among them, a funnel-shaped material guide funnel 8 is provided at the lower end of the liquid adding filter box 5, and the outer wall of the pressure tank body 1 is provided with a liquid adding port 9 connected to the bottom end of the material guide funnel 8.

[0027] During operation, the three-proof paint can be filled into the pressure tank without opening the cover. When the three-proof paint concentrate is injected into the pressure tank, the three-proof paint concentrate is injected into the liquid filling filter box 5 through the liquid filling pipe 7.
