Description

Technical Field

[0001] This utility model relates to a stirring inner tank structure. Background Technology

[0002] Currently available mixing liners on the market have a recessed shell formed on the bottom wall by stamping. A motor is mounted on the outside of the shell, and the motor's shaft passes through the shell into the interior of the liner, connecting to a mixer for mixing. However, in actual production, because the inner liner and shell need to be molded separately, both processes require annealing during molding and stamping. This makes the manufacturing process overly complex and prone to problems such as inner liner or shell breakage during stamping, resulting in a high scrap rate.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to propose a stirring inner liner structure. Using this structure to produce stirring inner liners can reduce the number of annealing cycles and significantly improve the product qualification rate.

[0005] To achieve the above objectives, this utility model provides a stirring inner liner structure, which includes an inner liner body and a shell. The bottom wall of the inner liner body has an assembly hole in the middle. The shell is open at the top, and the bottom wall of the shell is lower than the bottom wall of the inner liner body. The bottom wall of the shell is parallel to the bottom wall of the inner liner body. The shell has a shaft hole at the central axis of the inner liner body, and the outer edge of the shell is welded to the edge of the assembly hole.

[0006] In one or more embodiments, the bottom wall of the housing has a plurality of mounting holes distributed circumferentially around the shaft hole.

[0007] In one or more embodiments, the bottom wall of the housing has a recessed annular groove around the shaft hole.

[0008] In one or more embodiments, the shell is bent outward at the upper opening to form an annular plane, the outer side wall of the annular plane forms the outer edge, and the upper and lower end faces of the annular plane are flush with the upper and lower end faces of the bottom wall of the inner liner body.

[0009] In one or more embodiments, both the inner liner body and the outer shell are made of aluminum alloy or stainless steel.

[0010] Compared with the prior art, the advantages of this utility model are: by setting the shell, which originally required annealing and stamping, into a split structure, that is, the inner liner forming process and the shell forming process are separated and formed by independent material processing, and then fixed by welding in the later stage, the annealing process is reduced and the product qualification rate is improved.

[0012] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0013] See appendix Figure 1-2 This application provides a stirring liner structure, which includes an inner liner body 1 and a shell 2. The bottom wall of the inner liner body 1 has an assembly hole 3 in the middle. The shell 2 is open at the top, and the bottom wall of the shell 2 is lower than the bottom wall of the inner liner body 1. The bottom wall of the shell 2 is parallel to the bottom wall of the inner liner body 1. The shell 2 has a shaft hole 4 at the central axis of the inner liner body 1. The shaft hole is used for the motor shaft or bearing to pass through. The outer edge of the shell 2 is welded to the edge of the assembly hole 3. After the inner liner body and the shell are produced separately, they can be welded together by automated welding equipment to form an integral structure. The stirring liner produced using this structure can reduce the number of annealing processes, reduce production difficulty, and improve the product qualification rate.

[0014] The bottom wall of the housing 2 has a plurality of mounting holes 5 distributed around the shaft hole 4 in a circumferential direction. The mounting holes are used for mounting the motor bracket to facilitate fixing the motor.

[0015] The bottom wall of the housing 2 is provided with a recessed annular groove 6 around the shaft hole 4. The annular groove is matched with a sealing ring for installation and use to improve the sealing performance of the shaft hole.

[0016] The shell 2 is bent outward at the upper opening to form an annular plane 7. The outer side wall of the annular plane forms the outer edge. The upper and lower end faces of the annular plane 7 are flush with the upper and lower end faces of the bottom wall of the inner liner body 1 to ensure that the bottom wall of the inner liner body will not be uneven after the shell is welded.

[0017] Both the inner liner body 1 and the shell 2 are made of aluminum alloy or stainless steel. The specific materials can be selected according to actual production and are not limited here.

[0018] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
