Description

Technical Field

[0001] The utility model relates to the field of oily acrylic resin, in particular to an emergency reaction termination device for safe production of oily acrylic resin. Background Art

[0002] In the synthetic resin industry, the Redox (oxidation-reduction) reaction process needs to be terminated frequently. The conventional practice is to add terminators to avoid runaway reactions during the process.

[0003] The specific method is generally to push the terminator into the reactor by the pressure of nitrogen, but pushing it into the reactor only drops it into a certain point in the reactor, so the terminator is unevenly dispersed, the termination efficiency is low, and the termination effect is not ideal. Moreover, as the terminator decreases, the nitrogen pressure gradually decreases, resulting in insufficient pressure for subsequent use, thereby affecting the subsequent termination work. If the pressure is to be kept constant, nitrogen needs to be punched for each termination, which is time-consuming and labor-intensive, affecting efficiency.

[0004] Therefore, it is necessary to propose an emergency reaction termination device for safe production of oily acrylic resin to solve the above problems. Utility Model Content

[0030] In order to facilitate the resetting of the rotating tube 7 , a fixing block 25 is provided at the position corresponding to the inner cavity of the top shell 3 and the protruding piece 26 , and a resetting spring 18 for resetting the protruding piece 26 is provided between the fixing block 25 and the protruding piece 26 .

[0031] As another embodiment, a pressurizing mechanism is further provided on the basis of the above, and the pressurizing mechanism includes a plug plate 10 movably and sealably provided on the inner side of the nitrogen pressurizing tank 2, a lifting frame 5 is provided above the nitrogen pressurizing tank 2, a push-pull column 11 extending to the inner side of the nitrogen pressurizing tank 2 and used to drive the plug plate 10 to rise and fall is provided at the bottom of one end of the lifting frame 5, a screw rod 20 driven to rotate by a motor 23 is rotatably connected to the inner side of the fixed frame 6, in this embodiment, a rotating shaft 22 is fixedly connected to the bottom of the screw rod 20, and the outer side of the screw rod 20 is threadedly matched with a lifting block 21, and the end of the lifting frame 5 away from the push-pull column 11 is fixedly connected to the side wall of the lifting block 21;
