Chemical liquid raw material small packing barrel

Abstract

The invention discloses a chemical liquid raw material small packing barrel, and relates to a small packing barrel. An upper cover (35) is arranged on a bottle opening (17); an inner projection ring (19) is arranged at the lower part of the inner wall of the bottle opening; the lower part of a base plate (12) of the inner cover is pressed at the upper part of the inner projection ring; a lower projection pipe (26) is arranged on the lower surface of the base plate; the lower part of a lifting cylinder (13) is inserted in the lower projection pipe; a sealing ring (27) is arranged on the lower end edge of the lifting cylinder; a lock ring (33) is arranged on the upper end edge of the lifting cylinder; two ends of a spring (32) are ejected to the lock ring and the base plate; a projection baris arranged on the upper surface of a lower plate (25) in the lifting cylinder; at least one filling hole (14) is formed near the base plate; an outer orifice of the filling hole is as high as or higher than the sealing ring; a pouring hole (8) is formed in the base plate; and the pouring hole is closed by a sealing piece (5). By use of an automatic closing structure of the lifting cylinder and closing of the pouring hole by the sealing piece, the air contact in filling is reduced.

Description

【Technical field】 [0001] The invention relates to a small packaging barrel, in particular to a small packing barrel for chemical liquid raw materials. 【Background technique】 [0002] It is known that various chemical reagents obtained during crude oil refining, among which chemical products such as butane, pentane, n-hexane, heptane, octane, petroleum ether, solvent oil and aromatic hydrocarbons need to be sold after production and acquisition, these products either have Volatile, flammable, explosive, or highly toxic; in view of this, it is necessary to use explosion-proof lighting and ventilation facilities in storage. It is even more forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials, and when filling, there will be leakage and splashing when the filling tube is inserted into the bottle mouth, so a large amount of volatile gas accumulat...

AI Technical Summary

Problems solved by technology

The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials. When filling, there will be leakage and splashing when the filling tube is inserted into the bottle mouth, so a large amount of volatile gas accumulates in the air in the workshop, and more importantly, , for some high-purity products, once exposed to air for too long, the quality will decline
