[0017] Embodiment 1:

[0018] Please refer to Figure 1 A self-sealing discharging device includes a container body 110, the container body 110 is provided with a self-sealing module 120, the connection mode of the self-sealing module 120 and the container body 110 can be flange connection, can also be interference fit and the like; the self-sealing module 120 includes a fixed seat 122, the fixed seat 122 is arranged at the bottom of the container body 110, the bottom of the container body 110 is provided with the fixed seat 122, the middle part of the fixed seat 122 is provided with a through hole, the through hole is provided with a discharging pipe 121, the discharging pipe 121 extends below the fixed seat 122, one end of the discharging pipe 121 located outside the fixed seat 122 is provided with an elastic component, one end of the elastic component is connected with the fixed seat 122, and the other end is connected with the discharging pipe 121. Through the arrangement of the elastic component, when the discharging pipe 121 is separated from the material receiving component or the discharging pipe 121 is not subjected to other external forces, the discharging pipe 121 will be subjected to the elastic force of the elastic component downwards, so that the self-sealing between the material storage cavity 111 and the feeding port 129 is realized. Under the action of no external force, the bottom outlet of the reaction kettle can realize self-sealing, therefore, the reaction kettle can be freely transferred, the replacement and maintenance of the reaction kettle are more convenient, and offline cleaning of the reaction kettle can be realized.

[0019] The elastic component comprises a spring 123, one end of which is connected with the fixed seat 122 and the other end of which is connected with the discharge pipe 121. When the discharge pipe 121 is separated from the material receiving component or the discharge pipe 121 is not subjected to other external force, the discharge pipe 121 will be subjected to the downward elastic force of the spring 123, so as to realize the self-sealing between the storage cavity 111 and the feeding port 129.

[0020] In the present application, a flow-through cavity is formed in the discharge pipe 121, the feeding port 129 of the flow-through cavity is located in the fixed seat 122, and the discharge port 128 of the flow-through cavity is close to the end of the discharge pipe 121.

[0021] In the present application, the self-sealing module 120 comprises an inner sealing ring 125 and an outer sealing ring 126. The inner sealing ring 125 is arranged between the fixed seat 122 and the discharge pipe 121, and the outer sealing ring 126 is arranged between the fixed seat 122 and the container body 110. The inner sealing ring 125 is used to seal the fitting gap between the fixed seat 122 and the discharge pipe 121, and the outer sealing ring 126 is used to seal the assembly gap between the fixed seat 122 and the container body 110.
