Description

Technical Field

[0001] The utility model relates to the technical field of barrel covers, in particular to a breathable barrel cover. Background Art

[0002] Chemical barrels are containers for various chemical raw materials. They are usually used to store and transport chemical raw materials because of their stable performance, not easy to react with chemical raw materials, and excellent corrosion resistance. Most of the existing chemical barrel covers are integrated and connected to the chemical barrel cover through threaded sealing. The air permeability is poor. Some chemical raw materials will produce gas expansion during transportation. If the air permeability is not good, it cannot be discharged from the barrel in time, which will cause a certain degree of damage to the chemical barrel and affect the overall transportation of chemical raw materials.

The threaded grooves 17 formed around the inner wall of the barrel cover body 1 are used to rotatably install the barrel cover body 1 on the chemical barrel. The through hole 11 formed at the center of the barrel cover body 1 can realize ventilation between the inside and outside of the chemical barrel, so that part of the gas generated during the transportation of chemical raw materials in the barrel can be discharged. The second air permeable portion allows the remaining gas generated in the barrel to be discharged. The card groove 16 is used to clamp and fix the card block 22. The convex ring 15 is used to press and position the barrel cover body 1 when connected and installed on the chemical barrel. A number of connecting blocks arranged in a circle are provided between the stop ring 13 and the barrel cover body 1. The inclination direction of the stop teeth 14 is consistent. The stop teeth 14 are used to cooperate with the anti-theft teeth on the barrel body. When rotated in a certain direction, it can exceed the ultimate tensile strength of the connecting block, thereby realizing the rotation and opening of the barrel cover body 1 and allowing the stop ring 13 to remain on the barrel body.

[0026] The first ventilating portion includes a circular pad 21, a plurality of connection posts 23 in a uniform array are fixedly arranged on the upper surface of the circular pad 21, a clamping block 22 is fixedly arranged above the connection posts 23, and a mesh grille 2 is fixedly arranged on the inner wall of the clamping block 22.

The main return pipe 36 is used to return the liquid flowing to the second turning point to the lower end of the connecting channel 31. When there is liquid at the upper end of the main return pipe 36, the side flow pipe 391 is used to allow the liquid to flow back to the lower end of the connecting channel 31. When there is no liquid at the upper end of the main return pipe 36, the liquid is prevented from flowing from the side flow pipe 391 to the upper end of the main return pipe 36.
