Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings. As shown in the figure, a special alloy pre-reactor plate spring transmission shaft structure includes a transmission shaft 7. The end of the transmission shaft is provided with a shoulder 71, which abuts against the shaft shoulder. The threaded section of the thread retaining ring 1 is screwed with the adjusting nut 2, and the inner side of the end of the adjusting nut is provided with a spring seat 4, and the spring seat is provided with a boss 41, and the shape of the boss and the end of the adjusting nut are complementary and Fastened together, the disc spring group 3 set on the transmission shaft is set between the threaded retaining ring 1 and the spring seat 4, and the two ends of the disc spring group respectively abut against the threaded retaining ring and the spring seat; The foundation seat 8 connected on the transmission shaft also abuts against the other s...

Abstract

The invention discloses a special alloy pre-reactor plate spring transmission shaft structure. The special alloy pre-reactor plate spring transmission shaft structure comprises a transmission shaft, wherein the transmission shaft is provided with a shaft shoulder; a thread baffle ring is in threaded connection with an adjusting nut; a spring seat is arranged below the adjusting nut; the spring seat is buckled with the adjusting nut; a disc spring group is arranged between the thread baffle ring and the spring seat; the disc spring group abuts against the thread baffle ring and the spring seat; a foundation seat further abuts against the spring seat; the foundation seat is connected with an oil cylinder with an oil injection hole; the oil cylinder is internally provided with an oil piston; the oil piston abuts against the spring seat; the foundation seat abuts against sectional shaft sleeves; a sealing ring is arranged between the sectional shaft sleeves; the transmission shaft is provided with a thread section; and a sealing ring is arranged between a locking nut and the sectional shaft sleeves. The special alloy pre-reactor plate spring transmission shaft structure has the advantages that the sectional shaft sleeves guarantee the convenience of replacement; after the disc spring group is pressed, guarantees can be continuously provided for the sealing performance of the shaft sleeves through deformation, and the working performance of the transmission shaft is prolonged; and the size of the deformation amount is adjusted through the disc spring group so that the size of an acting force between the sectional shaft sleeves is changed.

Description

technical field [0001] The invention relates to the field of fluorine chemical industry, in particular to a sealed transmission structure of a pre-reactor. Background technique [0002] The transmission shaft is the core component of the pre-reactor. Driven by the motor, the shaft and the blades on the shaft rotate continuously while making axial reciprocating motions to stir, mix and transport the materials to the end. [0003] The reaction section of the pre-reactor reacts with strong acid and materials, and the corrosion degree is large, so the shaft contacting the corrosive medium is made of nickel-based alloy. Due to the requirements of production indicators and transmission torque, the shaft diameter of the pre-reactor is generally above φ200mm, and the length is related to the material conveying position and reaction time, and is generally above 5 meters. In general, considering the manufacturing and investment costs, the inside of the transmission shaft Made of carb...
