The utility model not only can realize reliable connection of shafts, but also can be used in corrosive environment in glass-lined reactors.

Description

A kind of axle coupling arrangement of glass-lined kettle

Technical field

The utility model relates to a kind of chemical industry operation unit, relates in particular to a kind of axle coupling arrangement of glass-lined kettle.

Background technique

Glass-lined kettle is the chemical industry operation unit of using always, especially for the stirring reaction of strong corrosive media.In recent years, environmental protection and safety in production came into one's own day by day, and the sealing of increasing use magnetic agitation replaces traditional mechanical seal on glass-lined kettle.Different with traditional mechanical seal is that the output shaft of magnetic agitation sealing is positioned at the inside of reactor with being connected of stirring shaft, even is in the medium of deep-etching.The axle coupling arrangement of existing glass-lined kettle is made up of parts such as the shaft extension part of output shaft, stirring shaft spindle noses, the output shaft shaft extension is partly inserted the inner formation of stirring shaft spindle nose thread taper and is connected, this connection part generally is positioned at beyond the still mouth sealing surface of reactor, the corrosion protection sealing configuration is not set, therefore can not in corrosive media environment, uses.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, provides a kind of being applicable under the still internal corrosion environment to use, and axle connects the axle coupling arrangement of more reliable glass-lined kettle.

For achieving the above object, the utility model adopts a kind of axle coupling arrangement of glass-lined kettle, comprise the output shaft shaft extension, the stirring shaft spindle nose, the anti-reverse turn nut of making by resistant material, divide half snap ring, form on the output shaft shaft extension cylindrical and the suitable circular groove of branch half snap ring, divide half snap ring to be set in this circular groove, anti-reverse turn nut is set in the axial end of stirring shaft spindle nose, on the inwall of the upper end part of anti-reverse turn nut, be provided with and divide half snap ring cylindrical suitable shoulder rank, both constitute the shoulder rank and cooperate, the end portion of anti-reverse turn nut is threaded with stirring shaft spindle nose formation, the thread rotary orientation direction of anti-reverse turn nut is opposite with the connection thread rotary orientation direction of following spindle nose, on the upper end part of anti-reverse turn nut and end portion inwall, all be provided with the O RunddichtringO, two O RunddichtringOs respectively with the output shaft shaft extension, the cylindrical formation of stirring shaft spindle nose is sealed and matched.

The utility model further is set to output shaft shaft extension end and forms outside thread, constitutes with the internal thread of stirring shaft spindle nose to be threaded, and the output shaft shaft extension is conical shaft extension, and the stirring shaft spindle nose forms suitable conical bore, and both constitute tapering and connect cooperation.

The utility model is compared with prior art, by two O of place RunddichtringOs on the anti-reverse turn nut carbon steel part of enamel stirring shaft is kept apart fully with Korrosionsmedium, prevent that it from being corroded, and anti-reverse turn nut, branch half snap ring, output shaft shaft extension and stirring shaft spindle nose are all made by resistant material, both realized the positive connection of axle, and be applicable to again under the still internal corrosion environment and use.

Description of drawings

Fig. 1 is the utility model example structure schematic representation.

Embodiment

As shown in Figure 1, the utility model specific embodiment is a kind of axle coupling arrangement of glass-lined kettle, the carbon steel, shafts part 2, stirring shaft spindle nose 3, anti-reverse turn nut 4, branch half snap ring 5 that comprise output shaft shaft extension 1, stirring shaft, wherein the end of output shaft shaft extension 1 forms outside thread, be threaded with the internal thread formation of stirring shaft spindle nose 3, form circular groove 11 on output shaft spindle nose 1 cylindrical, output shaft shaft extension 1 is conical, stirring shaft spindle nose 3 forms suitable conical bore, and both constitute tapering and connect cooperation.The carbon steel, shafts part 2 of stirring shaft constitutes welding with the bottom of stirring shaft spindle nose 3, enamel 6 is wrapped in the joint of carbon steel, shafts part 2 and stirring shaft spindle nose 3, divide half snap ring 5 to be set in the circular groove 11 of output shaft spindle nose 1, anti-reverse turn nut 4 is set in both joints of output shaft spindle nose 1 and stirring shaft spindle nose 3, on the inwall of the upper end part of anti-reverse turn nut 4, be provided with and divide half snap ring, 5 cylindricals suitable shoulder rank 41, both constitute the shoulder rank and cooperate, the end portion of anti-reverse turn nut 4 is threaded with stirring shaft spindle nose 3 formations, the thread rotary orientation direction of anti-reverse turn nut 4 is opposite with the connection thread rotary orientation direction of stirring shaft spindle nose 3, all being provided with 7, two O RunddichtringOs 7 of O RunddichtringO on the upper end part of anti-reverse turn nut 4 and end portion inwall constitutes with the cylindrical of output shaft shaft extension 1 and stirring shaft spindle nose 3 respectively and is sealed and matched.

The utility model is compared with prior art, by two O of place RunddichtringOs 7 on the anti-reverse turn nut 4 inwall and the Korrosionsmedium of the carbon steel part 2 of stirring shaft are kept apart fully, prevent that it from being corroded, and anti-reverse turn nut 4, branch half snap ring 5, output shaft shaft extension 1 and stirring shaft spindle nose 3 are all made by resistant material, both realized the positive connection of axle, and be applicable to again under the still internal corrosion environment and use.
