The pressure gauge 8 is used to detect the pressure value inside the reactor feeding and deoxidizing equipment, and the pressure gauge 8 is respectively connected to the cut-off valve 9, the vacuum valve 10, the vacuum pump 12, and the discharging butterfly valve 4.

[0034] In the embodiment, by setting the pressure gauge, it is convenient for the staff to timely check the pressure inside the reactor feeding and deoxidizing equipment housing.

[0035] Specifically, in this embodiment, four pipelines are externally connected to the reactor feeding and deoxidizing equipment housing, including a material pipeline 3 connected to the material 1, an air input pipeline connected to the air compressor, a vacuum pipeline 11 connected to the vacuum pump 12, and a discharging pipeline connected to the feed port of the reactor 13; a feed valve 6 is provided on the material pipeline 3, a cut-off valve 9 is provided on the air input pipeline, a vacuum valve 10 is provided on the vacuum pipeline 11, and a discharging butterfly valve 4 is provided on the discharging pipeline.

[0038] In the embodiment, after the deoxidation process, compressed air is input. Since the pressure difference between the positive pressure of the compressed air and the inside of the vacuum hopper 5 can perform backwashing on the filter element 7 to improve the service life of the filter element.

[0039] Specifically, in this embodiment, a feeding timer is provided on the reactor feeding and deoxidizing equipment. The feeding timer measures the feeding time of the reactor feeding and deoxidizing equipment, and the feeding timer is respectively connected to the feed valve 6 and the vacuum pump 12.

[0040] In the embodiment, the feeding timer is connected to the feed port valve and the key equipment of negative pressure conveying, namely the vacuum pump, so as to control the material situation of negative pressure conveying and facilitate the adjustment of the material conveying amount. The feeding and deoxidizing equipment for the reaction kettle deoxidizes through a vacuum pump with a high vacuum degree, reducing the oxygen content in the vacuum hopper and greatly improving the safety of the equipment.

[0041] When the feeding and deoxidizing equipment for the reaction kettle works, the vacuum pump 12 starts, the on-off valve 9 closes, the discharging butterfly valve 4 closes, the vacuum valve 10 opens, and the feed port valve 6 opens.

When the set feeding time arrives, the feed port valve 6 closes, and the deoxidation treatment of the material entering the vacuum hopper starts.

[0042] The vacuum pump 12 continues to operate to evacuate the feeding and deoxidizing equipment for the reaction kettle. The pressure gauge 8 is used to detect the pressure value inside the feeding and deoxidizing equipment for the reaction kettle. The detected pressure value gradually increases. After reaching the predetermined pressure value, the vacuum valve 10 closes and the vacuum pump 12 closes. The state of the material in the vacuum hopper is as shown in the appendix. Figure 5 Then, the discharging process of the vacuum hopper starts.

[0043] The on-off valve 9 opens, and the compressor fills compressed air into the feeding and deoxidizing equipment for the reaction kettle. The positive pressure of the compressed air and the pressure difference in the vacuum hopper 5 are used to backflush and clean the filter element 7. The on-off valve 9 closes, and the discharging butterfly valve 4 opens. Under the push of a slightly positive pressure, the material 1 is pressed from the vacuum hopper 5 into the reaction kettle 13. Since the material 1 has undergone vacuum deoxidation in the vacuum hopper 5, the oxygen content in the vacuum hopper is sufficiently reduced, which can effectively prevent the material 1, the organic solvent in the reaction kettle 13, and the oxygen in the air from coming into contact, thereby reducing the probability of explosion and fire.
