Description

Technical Field

[0001] The utility model relates to the technical field of vacuum material suction devices, in particular to a vacuum material suction device for neopentyl glycol distillation processing. Background Art

[0002] In the preparation process of neopentyl glycol, a distillation process is required. Before distillation, the concentrated liquid in the concentration kettle needs to be pumped into the distillation kettle through a vacuum suction device for distillation processing. The positive vacuum suction device can quickly and conveniently perform the loading work. However, since the bottom of a general hopper is flat, the suction pipe head of the vacuum suction device is needle-shaped, which makes it easy for residue to remain at the bottom during loading. Moreover, since the concentrated liquid is in liquid form, the general suction pipe head is easy to float up and easily float on the liquid surface to inhale air, affecting the vacuum loading effect. Generally, there is no filtering structure for the liquid material, which easily inhales impurities during loading. Therefore, the suction pipe head part of the vacuum loading device needs to be provided with some structures that can reduce the residual material in the hopper, avoid inhaling air, and provide filtering effect. For this reason, the utility model proposes a vacuum suction device for neopentyl glycol distillation processing to solve the above problems. Utility Model Content
