Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1, 2 and 3, the anti-explosion device of the synthetic reaction kettle of the antioxidant 3114 of the embodiment comprises a communication pipe 1 and an anti-explosion barrel 2, wherein one end of the communication pipe 1 is communicated with the reaction kettle, the other end of the communication pipe is communicated with the anti-explosion barrel 2, the anti-explosion barrel 2 is of a conical structure, the anti-explosion barrel 2 is provided with an air outlet 21, an elastic anti-explosion plate 3 and a connecting rod 4 are arranged inside the anti-explosion barrel 2, one end of the connecting rod 4 is connected with the anti-explosion plate 3, the other end of the connecting rod is movably connected with the anti-explosion barrel 2, an extension spring 5 is arranged outside the connecting rod 4, the inner wall of the anti-explosion barrel 2 is provided with a plurality of bulges 6, the plurality of bulges 6 are positioned on the same circle, the plane where the circle is positioned is perpendicular to the axis of the anti-explosion barrel 2, when the anti-explosion plate 3 is positioned below the bulges 6, the anti-explosion plate 3 is in contact with the inner wall of the anti-explosion barrel 2, during pressure relief, the explosion-proof sheet 3 is positioned above the bulge 6, and the diameter of the explosion-proof cylinder 2 and one end connected with the communication pipe 1 is smaller than that of the free end of the explosion-proof cylinder 2.
Under normal conditions (namely when the pressure in the reaction kettle does not reach a certain value), the explosion-proof sheet 3 is positioned below the bulge 6, and the explosion-proof sheet 2 is contacted with the inner wall of the explosion-proof cylinder 2, so that the reaction kettle is in a closed state; when the air pressure in the reaction kettle reaches a certain value and the air in the reaction kettle needs to be discharged for pressure relief, the explosion-proof sheet 3 moves to the other side of the bulge 6 (namely above the bulge 6) under the action of the internal pressure of the reaction kettle, and because the explosion-proof cylinder 2 is of a conical structure, a gap is formed between the explosion-proof sheet 3 and the inner wall of the explosion-proof cylinder 2, and the bulge 6 can support the explosion-proof sheet 3 and discharge all or most of the air in the reaction kettle, so that the internal pressure of the reaction kettle is normal or the pressure is small; after pressure relief, the explosion-proof sheet 3 is pushed to the lower part of the bulge under the action of the elastic force of the expansion spring 5, so that the reaction kettle is restored to a sealing state.
