Problems solved by technology
However, the current polymerization kettle needs to move the transmission device (motor, reducer, etc.) and the kettle body when repairing or replacing vulnerable parts. This operation is extremely inconvenient, increases the difficulty of operation, and prolongs the maintenance time
[0003] In addition, in the horizontal polymerization kettle, the deflection caused by the self-weight of the shaft will affect the normal operation of the sealing member, so that the sealing performance in the kettle will be affected to a certain extent, and it must be ensured that the sealing performance is good during production, so as to ensure the inside of the kettle. High vacuum meets the requirements, so this defect needs to be solved urgently

The invention provides a transmission end for a polymerization kettle, which is characterized in that the transmission end comprises a shaft body which has a first end part and a second end part, a cylinder body which is arranged at the periphery of the middle part of the shaft body, an end cover which is correspondingly arranged at the first end part of the shaft body and is connected with the cylinder body, a connecting flange which is correspondingly arranged at the second end part of the shaft body and is provided with a first end surface connected with the cylinder body and a second end surface connected with a kettle body, a packing sealing assembly which is arranged at the periphery of the second end part of the shaft body and is connected with the second end surface of the connecting flange, a mechanical sealing assembly which is arranged at the periphery of the shaft body, is positioned in the cylinder body and is adjacent to the packing sealing assembly, and a sealing ring assembly which comprises a plurality of sealing rings. The transmission end for a polymerization kettle can play a good sealing role and guarantee a high vacuum degree in a polymerization kettle when used in the polymerization kettle; and the replacement work of vulnerable parts becomes convenient.
Description
technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a transmission end for a polymerization kettle. Background technique [0002] The polymerization kettle is usually composed of a kettle body, a kettle cover, a jacket, an agitator, a transmission device, a shaft seal device, etc. The shaft sealing device acts as a seal on the polymerization kettle. The shaft seal device is usually provided with wearing parts such as rubber sealing components, and the polymerization kettle needs to be inspected regularly, and these wearing parts need to be replaced during the inspection process to ensure the normal operation of the polymerization kettle. However, when the current polymerization kettle is overhauled or replaced with wearing parts, it is necessary to move the transmission device (motor, reducer, etc.) and the kettle body. This operation is extremely inconvenient, increases the difficulty of operation, and prolongs the ma...
