Description

Technical Field

[0001] The utility model relates to the field of mixers, in particular to a shell structure of a mixer. Background Art

[0002] A mixer is a machine that uses mechanical force and gravity to evenly mix two or more materials. The mixing process also increases the contact surface area of ​​the materials, promoting chemical reactions and accelerating physical changes. It is widely used in the fertilizer, chemical, and pharmaceutical industries.

[0003] A search revealed a Chinese patent application with publication number CN208049755U, which discloses a horizontal drum mixer comprising a cylindrical shell with closed ends, a rotating shaft disposed within the cylindrical shell, and a feed port and a discharge port disposed on the cylindrical shell. The rotating shaft is provided with a number of mixing tools distributed along its axial direction. The mixing tools are numbered sequentially, starting from the end closest to the feed port. The angle between two adjacent mixing tools is 102°, and the angle between the tenth mixing tool and the first mixing tool is 180°. The feed port is tangent to the sidewall of one end of the cylindrical shell and faces directly upward, while the discharge port is tangent to the sidewall of the other end of the cylindrical shell and faces directly downward. By rationally arranging the mixing tools, dynamic balance is achieved without the need for additional counterweights. Furthermore, improvements to the feed port and discharge port address the issues of uneven feeding and splashing discharge.

[0004] However, in the actual mixing process, all areas of the inner wall of the shell are in direct contact with the material. The inner wall of the shell is usually a smooth surface, which results in insufficient friction and poor mixing effect. Utility Model Content

[0005] In order to further improve the friction resistance and mixing effect, the present application provides a shell structure of a mixer.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. By arranging spaced friction strips inside the shell, spacer grooves for material storage are formed between adjacent friction strips, which effectively increases the friction resistance in contact with the material, delays the efficiency of material transportation, and allows the material to be stirred and mixed in the shell for a longer time, thereby achieving the purpose of improving the mixing effect;

[0019] 2. The friction strip is made of carbon steel with high strength, hardness and wear resistance, which improves the wear resistance and effectively improves the overall structural strength and compressive performance of the shell;

[0020] 3. The design of the baffle plate can partially block the material from being discharged directly from the discharge port, allowing the material to be stirred and mixed longer in the shell, improving the final mixing uniformity and sufficiency. The friction strip embedded in the baffle plate can further reinforce it.

[0021] 4. The matching design of the discharge port and the blanking port makes the discharge structure more integrated, which improves the mixing time and uniformity of the materials during mixing. After the mixing is completed, the materials in the shell can be completely discharged from the blanking port to avoid some materials remaining inside the shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] A shell structure of a mixer, such as Figure 1 and Figure 2 As shown, it includes a shell 1, a feed port 2 is provided at the top of one end of the shell 1, and a feed hopper 3 is provided at the feed port 2, a discharge port 9 is provided on the bottom wall of the other end of the shell 1, and the bottom inner wall of the shell 1 is an arc surface, and a friction strip 4 is provided on the inner wall of the shell 1, and the friction strip 4 is fixed to the inner wall of the shell 1. In other embodiments, the friction strip 4 can also be detachably connected to the shell 1, and the friction strip 4 extends along the length direction of the shell 1, and the friction strip 4 is evenly distributed around the circumference of the inner wall of the shell 1, and a spacing groove 5 for accommodating part of the material is formed between adjacent friction strips 4. In this embodiment, the friction strip 4 is made of carbon steel strips, which have good high strength, hardness and wear resistance. In this way, the friction resistance of the contact with the material can be improved by setting the friction strip 4, the efficiency of material transportation can be delayed, the material is stirred and mixed in the shell for a longer time, and the mixing effect is effectively improved. At the same time, the overall structural strength and pressure resistance of the shell 1 are also improved to a certain extent.

[0029] like Figure 1 and Figure 2 As shown, both ends of the friction strip 4 extend to the end walls of the shell 1. The friction strips 4 on the end walls are evenly distributed around the circumference, and the length direction of the friction strips 4 on the end walls is toward the center of the circle. The friction strips 4 on the end walls include long strips 6 and short strips 7. The long strips 6 and the short strips 7 are alternately distributed. In this way, more areas on the end wall are provided with friction strips 4 to achieve a better setting effect.

[0030] like Figure 2 and Figure 3As shown, a baffle plate 8 is protruding from the bottom wall of the shell 1 near the discharge port 9. The baffle plate 8 is located on the side of the discharge port 9 close to the feed port 2. The friction strip 4 is embedded in the baffle plate 8 to further limit and reinforce the baffle plate 8. The height of the baffle plate 8 is about one-fourth of the total height of the shell 1. The baffle plate 8 is used to partially block the material. In this way, during the actual use of the mixer, the material will not be discharged directly from the discharge port 9 when it is stirred and transported toward the discharge port 9. It will be discharged from the discharge port 9 after the material height exceeds the baffle plate 8, which effectively prolongs the stirring and mixing time of the material in the shell 1 and achieves better stirring and mixing effect.

[0031] like Figure 2 and Figure 3 As shown, a drop port 10 is further provided at the bottom of the shell 1, and the drop port 10 is located on the side of the baffle plate 8 facing away from the discharge port 9. The diameter of the drop port 10 is much smaller than the diameter of the discharge port 9. The drop port 10 plays the role of auxiliary drop material. When the material is stirred and mixed, only a small amount of material is discharged from the drop port 10, which does not affect the continuous increase of the material in the shell 1 and then passes the baffle plate 8 and is discharged from the discharge port 9. Most of the material is mainly discharged from the discharge port 9, and after the mixer completes the mixing, the remaining material in the shell 1 can be completely discharged through the drop port 10 to avoid accumulation.

[0032] like Figure 2 and Figure 3 As shown, a discharge connector 11 is provided at the bottom of one end of the shell 1 corresponding to the discharge position, and the discharge connector 11 has an outlet 12 for discharging. The discharge port 9 and the drop port 10 are both located inside the outlet 12. The design of the outlet 12 realizes the overall integrated discharge of the shell 1, which is convenient for the unified connection of subsequent discharge components to achieve better discharge effect.

[0033] like Figure 1-Figure 3 As shown, the bottom of the housing 1 is provided with supporting feet 13, and there are multiple supporting feet 13 and they are symmetrically arranged. The supporting feet 13 are used to provide good support for the housing 1, thereby improving the stability of the housing 1.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
