Description

Technical Field

[0001] The utility model relates to the technical field of unloading devices, in particular to a device for improving the unloading efficiency of dimethyl carbonate. Background Art

[0002] Dimethyl carbonate is an organic compound with the chemical formula C3H6O3. It is a low-toxic, environmentally friendly, and widely used chemical raw material. It is an important organic synthesis intermediate. Its molecular structure contains functional groups such as carbonyl, methyl, and methoxy. It has a variety of reaction properties and is safe, convenient, less polluting, and easy to transport in production. Dimethyl carbonate is flammable, and its vapor can form an explosive mixture when mixed with air. It needs to be stored in a cool, dry, well-ventilated non-combustible warehouse.

[0003] Therefore, when unloading dimethyl carbonate, the stability of the dimethyl carbonate container should be maintained to prevent the dimethyl carbonate container from falling and causing damage to the container, causing dimethyl carbonate to leak and ignite, endangering the health of personnel and preventing property losses; when unloading, the existing truck unloading device usually overlaps one end of the unloading device on the rear of the truck and the other end is a belt conveyor, and the items are slid onto the belt conveyor for transportation. In the process of sliding of the item transportation storage box, it is very easy to fall due to friction, external factors such as incorrect sliding position, etc., which poses a great safety hazard. Since different trucks have different heights, the existing unloading device cannot adapt to trucks of different heights, and it is not easy to improve the unloading efficiency.

[0004] Therefore, it is necessary to design a device to improve the unloading efficiency of dimethyl carbonate. Utility Model Content
