Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the invention shown in the drawings and described with reference to the drawings are merely exemplary, and the invention is not limited to these embodiments.

Here, it should also be noted that, in order to avoid obscuring the present utility model due to unnecessary details, only the structures and/or processing steps closely related to the solution according to the present utility model are shown in the drawings, while omitting Other details that have little relationship with the utility model are described.

Referring to shown in Fig. 1, a kind of paint vacuum degassing device comprises: controller 1, vacuum pump 2, paint input pipeline 3, paint output pipeline 4, support 5 and the vacuum storage tank 6 that is installed on the support 5, described vacuum The top of the storage barrel 6 is provided with a main motor 7, and the bottom of the vacuum storage barrel 6 is provided with a weighing device 8. The vacuum storage barrel 6 includes a cylindrical barrel body 9, a conical barrel bottom 10, and a barrel body 9.
