Problems solved by technology

[0002] During the production process of the resin, materials must be added in a vacuum state, but because the inside of the reactor is under negative pressure, it is easy to inhale the outside gas due to improper handling during the process of adding materials, which will cause the resin to oxidize and darken the color, affecting Product quality, so it is necessary to design new technology to solve the above problems

Embodiment Construction

[0010] Reference figure 1 . A vacuum feeding funnel applied to resin production, comprising a closed storage tank 1, the closed storage tank 1 is provided with a feeding pipe 2 extending into the closed storage tank 1, and a lower ball valve 3 is sequentially connected to the feeding pipe 2 through a pipeline , The middle sealing device 4, the upper ball valve 5, and the feeding funnel 6. The upper ball valve 5 and the lower ball valve 3 can protect the middle sealing device 4 by vacuum. The intermediate sealing device 4 is also provided with an air inlet pipe 7, and the air inlet pipe 7 is provided with a nitrogen valve 8, wherein the air inlet pipe 7 is fed with nitrogen, and materials are added through the feeding funnel 6.

[0011] In order to facilitate monitoring of the internal pressure of the intermediate sealing device 4, a pressure gauge 9 is provided on the intermediate sealing device 4.

[0012] In actual work, the steps are as follows:

[0013] 1) First open the nitro...

Abstract

The invention discloses a vacuum charging hopper applied to resin production. The vacuum charging hopper includes a sealed storage tank equipped with a charging pipe stretching into the sealed storage tank. A lower ball valve, a middle sealed device, an upper ball valve, and a charging hopper are connected to the charging pipe in order through pipelines, wherein the middle sealed device is also provided with an air inlet pipeline, in which a nitrogen valve is arranged. Through a reasonable design, the vacuum charging hopper utilizes nitrogen as a protective gas to drain away air in the funnel, and exempts a charging process from the influence of external air through control of the upper and lower valves, thus realizing vacuum charging. Therefore, the resin inside can be effectively protected so as to guarantee the resin quality.

Description

Technical field [0001] The invention relates to an industrial feeding funnel, in particular to a vacuum feeding funnel applied to resin production. Background technique [0002] In the resin production process, it is necessary to add materials in a vacuum state, but because the inside of the reactor is negative pressure, it is easy to inhale external air due to improper handling during the process of adding materials, which will cause the resin to oxidize and darken the color. Product quality, so it is necessary to design new technologies to solve the above problems. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a vacuum feeding funnel applied to resin production. [0004] The technical solutions adopted by the present invention to solve its technical problems are: [0005] A vacuum feeding funnel applied to resin production includes a closed storage tank provided with a feeding pipe extending into the close...
