Description

Technical Field

[0001] The utility model relates to the technical field of triacetin processing, in particular to a packaging can for triacetin. Background Art

[0002] Glyceryl triacetate, also known as triacetin (GTA), is a colorless, odorless, transparent, viscous oily liquid and is an intermediate for the preparation of many fine chemical products. Its boiling point is 258-260°C, density is 1.16g / mL, and refractive index is 1.429-1.431 at room temperature and pressure. Glyceryl triacetate is miscible with most organic solvents such as ethanol, ether, benzene, and chloroform, but is insoluble in mineral oil and slightly soluble in water. Its solubility in water at 25°C is only 5.9g / 100mL. It can be used as a soil hardener, a fungicide for vegetables and fruits, a fixative for spices, a cleaning disinfectant, and a food additive. In view of its good elasticity, air permeability, and suitable hardness, it is mainly used as a plasticizer for cigarette filters. At present, the annual production and demand of glyceryl triacetate in my country is more than 10,000 tons, making it a very popular chemical product and daily necessities. After production, glyceryl triacetate needs to be filled into packaging cans for storage.

The upper connecting piece 5 on the top seat 2 and the lower connecting piece 6 on the base 3 can connect and fix two adjacent tank bodies 1, so that multiple tank bodies 1 can be stably connected during transportation to avoid displacement between the tank bodies 1 during transportation, thereby ensuring the safety of triacetin during transportation. Considering that the overall weight of the tank body 1 is heavy after being filled with triacetin, the universal wheel 4 provided at the lower end of the base 3 can assist the tank body 1 in moving.

[0028] In a further preferred embodiment of the utility model, the top seat 2 and the base 3 are both square;

[0029] The square top seat 2 and the base 3 can make the overall structure more stable when multiple tank bodies 1 are arranged and connected.

[0030] In a further preferred embodiment of the utility model, the upper connecting member 5 and the lower connecting member 6 each include four connecting columns 51 arranged on the top seat 2 and the base 3, and the upper connecting member 5 and the lower connecting member 6 also include connecting holes 52 arranged on the top seat 2 and the base 3 and adapted to the connecting columns 51, and the connecting columns 51 and the connecting holes 52 are distributed in an interval and surrounding manner, and each of the connecting columns 51 is provided with a first threaded pin hole 53, and the lower end of the top seat 2 and the upper end of the base 3 are respectively provided with a second threaded pin hole 54 connected to the corresponding connecting hole 52, and a threaded pin 55 is provided in the inner thread of the first threaded pin hole 53 and the second threaded pin hole 54.

[0031] When connecting multiple tank bodies 1 filled with triacetin, first, turn each knob 42 in turn to make the threaded rod 41 at the lower end of the knob 42 move downward along the base 3, and the threaded rod 41 can push the universal wheel 4 to move downward until all the universal wheels 4 are pushed out of the storage groove. Then the production personnel can grasp the notch 21 on the top seat 2 to move the tank body 1 more easily. After the tank body 1 is moved to the side end of another tank body 1, the connecting column 51 on the top seat 2 and the base 3 of the tank body 1 is then connected to the connecting hole 52 on the top seat 2 and the base 3 of the adjacent tank body 1. After the connection, the first threaded pin hole 53 on each connecting column 51 on the connecting surface is concentric with the corresponding second threaded pin hole 54.
