Description

TECHNICAL FIELD

[0001] The utility model relates to the field of flange, concretely relates to a mixer sealing flange structure. BACKGROUND

[0002] At present, the tank flange installation method of the existing mixer usually adopts the welding mode to directly fix the flange at the tank mouth. However, the tank body of the mixer is relatively thin, due to the over-thickness and over-weight of the flange, the running phenomenon is prone to occur in the welding process, and the tank body can also be extruded to cause deformation. SUMMARY

[0003] In view of the above, the utility model aims at the problems of the prior art and provides a mixer sealing flange structure.

[0004] The mixer sealing flange structure in the scheme comprises a tank body, a thin flange and a thick flange, the tank body is provided with a tank mouth that is retracted, the thin flange is sleeved on the tank mouth and welded on the tank body, and the thick flange is sleeved on the thin flange and fixed.

[0005] Further, a plurality of holes are arranged on the thin flange and the thick flange, the holes on the thin flange and the thick flange are overlapped, and the thin flange and the thick flange are locked and fixed through rivets passing through the thin flange and the thick flange.

[0006] Further, the thin flange comprises an annular wall and an annular flange arranged on the annular wall, the annular wall is sleeved on the tank mouth of the tank body, and the bottom edge is welded and fixed with the outer wall of the tank mouth.

[0007] Further, the bottom edge of the thick flange is welded and fixed with the outer wall of the annular wall.

[0008] Beneficial effects: the combination design of the thin flange and the thick flange can effectively protect the tank body, and the accuracy of the flange position is ensured. BRIEF DESCRIPTION OF DRAWINGS

[0010] Fig. 2 It is the sectional view of the utility model;

[0011] Fig. 3 It is the structure explosion drawing of the utility model;

[0012] Fig. 1 is a tank body, tank mouth 101, thin flange 2, annular wall 201, annular flange 202, thick flange 3. DETAILED DESCRIPTION

[0013] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0014] Referring to Figs. 1 to 3 The mixer sealing flange structure shown in the drawing comprises a tank body 1, a thin flange 2 and a thick flange 3. The tank body 1 is provided with a retracted tank opening 101. The advantage of this design is that it can ensure the welding effect while avoiding the running phenomenon in the welding process. The thin flange 2 is sleeved on the tank opening 101 and welded on the tank body 1. The thick flange 3 is sleeved outside the thin flange 2 and fixed thereto. This design allows the thin flange 2 to be welded with the tank body 1 first. Because the thin flange 2 is light in weight, it is less likely to run and will not extrude the tank body 1. Moreover, it can ensure the accuracy of the flange and protect the tank body 1.

[0015] Secondly, there are two choices for the installation of the thick flange 3.

[0016] One is to open a plurality of holes on the thin flange 2 and the thick flange 3, and overlap the holes on the thin flange 2 and the thick flange 3. The thin flange 2 and the thick flange 3 are locked and fixed by rivets passing through the thin flange 2 and the thick flange 3. This method not only ensures the accuracy and stability of the flange, but also provides greater flexibility. The number and position of the holes can be selected according to different application scenarios and needs. Here, the number refers to the number of holes that need to be left for connection. In addition, this connection method can further protect the tank body 1, avoiding the thick flange 3 directly extruding the tank body 1 when under stress, thereby ensuring the safety of the entire system when subjected to external forces.

[0017] Secondly, the thin flange 2 can comprise an annular wall 201 and an annular flange 202 arranged on the annular wall 201. The annular wall 201 is sleeved on the tank opening 101 of the tank body 1 and the bottom edge is welded and fixed with the outer wall of the tank opening 101. Then the bottom edge of the thick flange 3 and the outer wall of the annular wall 201 are welded and fixed. This design is equivalent to thickening the tank opening 101 with the thin flange 2 and then welding the thick flange 3. It can also protect the tank body 1.

[0018] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
