the second flange is of an annular hollow structure, the second threaded holes with the number identical to that of the first threaded holes are formed in the periphery of the inner portion of the second flange, annular bosses with the diameter identical to that of the annular grooves are machined in the inner circle of the second flange, 2 x 45-degree oblique chamfers are machined in the periphery of the outer wall of one side, away from the second flange, of each annular boss, the roughness of the plane of each annular boss is 6.3, and the roughness of the outer wall of each annular boss is 12.5.

The utility model is further provided with: the number of the first threaded holes and the second threaded holes is 24, the first threaded holes are uniformly distributed around the inner part of the first flange by taking the axis of the first flange as the center, and the second threaded holes are uniformly distributed around the inner part of the second flange by taking the axis of the second flange as the center.

The utility model is further provided with: the diameter of the first flange is equal to that of the second flange, and the diameter of the inner circle of the first flange is equal to that of the inner circle of the second flange.

The beneficial technical effects of the utility model are as follows: through the oblique chamfer of annular boss, can play the effect of guide alignment when first flange docks with the second flange, saved and carried out the effect that the axiality was aimed at through large-scale mounting tool, the operation flow has been simplified, the installation time has been shortened, through the roughness that increases annular boss outer wall, make first flange and second flange butt joint after fix in advance, make things convenient for the operation that the bolt hole construction bolt was aimed at in later stage, thereby two links that need dock barrel installation alignment have been accomplished, be favorable to going on of welding process, increase the axiality of barrel.

Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

The utility model provides a mixer barrel butting flange, wherein two barrels to be butted are respectively inserted into the inner circles of a first flange and a second flange, an annular boss is inserted into an annular groove during butting, the annular boss can play a role of guiding alignment due to the fact that the annular boss is provided with an inclined chamfer, the butting work is convenient to carry out, the outer wall roughness of the annular boss is too large and has the effect of increasing friction force, after the annular boss is butted with the annular groove, the first flange and the second flange can be kept combined together to be pre-fixed without external force, the operation of aligning bolt holes at the later stage is convenient, the first flange and the second flange are connected and fixed through bolts, the links of installing and aligning the two barrels to be butted are finished, the welding processing is facilitated, and the coaxiality of the barrels is increased, and then welding the cylinder body and the butting flange.

While the utility model has been described with reference to a preferred embodiment, various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the utility model, and particularly, features shown in the various embodiments may be combined in any suitable manner without departing from the scope of the utility model.
