Description

Technical Field

[0001] This utility model relates to the field of mixers, and in particular to a mixer and its combined discharge structure. Background Technology

[0002] A mixer is a mechanical device that uses mechanical force and gravity to uniformly mix two or more materials. During the mixing process, the contact surface area of ​​the materials can be increased to promote chemical reactions and accelerate physical changes. It is widely used in fertilizers, chemicals, and pharmaceuticals.

[0003] A search revealed that Chinese patent CN209714822U discloses a high-efficiency synchronous slow-release wheat fertilizer production mixer. The simply mixed materials enter the equalization box and flow into the upper surface of the distribution plate. The materials are evenly distributed through the stepped distribution ports, and then the materials are collected back into the shell through the collection hopper. In this process, the materials from different parts are aggregated, thereby completing the initial uniform mixing of materials and improving the mixing quality of the mixer.

[0004] However, in actual use, the material is stirred and mixed by the rotating blades inside the shell and continuously conveyed towards the discharge direction, and finally discharged directly through the discharge port. The material is stirred and mixed in the shell for a short time, which can easily lead to uneven and insufficient mixing. Utility Model Content

[0005] To further improve the uniformity and thoroughness of mixing, this application provides a combined discharge structure.

[0006] This application provides a combined discharge structure, which adopts the following technical solution:

[0007] A combined discharge structure includes a housing and a main discharge port disposed on the housing. A baffle plate is disposed on one side of the housing corresponding to the main discharge port to prevent material from entering the main discharge port. A secondary discharge port is also disposed on the housing, and the secondary discharge port is located on the side of the baffle plate facing away from the main discharge port.

[0008] Optionally, the diameter of the secondary discharge port is smaller than the diameter of the main discharge port.

[0009] Optionally, the housing has a protruding discharge connector at the discharge point, and the discharge connector has a reserved mounting hole.

[0010] Optionally, the discharge connector has an outlet that communicates with the main discharge port and the secondary discharge port, both of which are located within the outlet.

[0011] This application also provides a mixer, which has the advantage of improving mixing uniformity, and specifically adopts the following technical solution:

[0012] A mixer includes the above-mentioned combined discharge structure, and further includes a drive assembly and a stirring roller. The stirring roller is rotatably connected inside the housing. The drive assembly drives the stirring roller to rotate. A feed inlet is provided at one end of the top of the housing, and the feed inlet is located at the end of the housing away from the main discharge outlet.

[0013] Optionally, a feed hopper is provided at the feed inlet, and the diameter of the feed hopper gradually decreases from top to bottom.

[0014] Optionally, the stirring roller is provided with stirring blades, which are spaced apart along the axial direction of the stirring roller, and each stirring blade has a different orientation angle.

[0015] Optionally, the bottom of the housing has supporting feet, which are symmetrically arranged, and the outer walls at both ends of the housing have reinforcing ribs.

[0016] Optionally, the outer side wall of the housing has a reinforcing strip, and the top of the support foot is fixed to the bottom wall of the reinforcing strip.

[0017] Optionally, the top of the housing is provided with a through groove, and a cover plate is provided on the housing corresponding to the through groove to close it. The cover plate covers the through groove, and multiple cover plates are provided at intervals along the axial direction of the housing.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The baffle plate on the shell can partially block the material from being discharged directly from the main discharge port. The material being blocked by the baffle plate can prolong the stirring and mixing time in the shell, improve the uniformity and fullness of mixing, and only discharge from the main discharge port in large quantities after the material height is higher than the baffle plate.

[0020] 2. The secondary discharge port can assist in the discharge process. During mixing, some of the mixture can be discharged from the secondary discharge port. After mixing is complete, the material inside the shell can be completely discharged through the secondary discharge port to avoid material residue inside the shell. 3. The secondary discharge port and the main discharge port are both located inside the outlet to improve the integration of the discharge and achieve discharge in the same area. This facilitates external discharge. In addition, the diameter of the secondary discharge port is smaller than that of the main discharge port, so that only a small amount of material is discharged from the secondary discharge port during mixing. This avoids the situation where a large amount of material is discharged from the secondary discharge port and the material inside the shell cannot exceed the baffle plate. The large amount of material is discharged from the main discharge port after the baffle plate has been fully mixed. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] A mixer, such as Figures 1-3 As shown, the device includes a housing 1, a drive assembly, and a stirring roller 2. The stirring roller 2 is equipped with stirring blades 3 and is rotatably connected inside the housing 1. The drive assembly drives the stirring roller 2 to rotate, thereby mixing and stirring the materials inside the housing 1. A feed inlet 4 is provided at the top of one end of the housing 1, and a combined discharge structure is provided at the bottom of the other end. A feed hopper 5 is provided at the feed inlet 4 of the housing 1. The diameter of the feed hopper 5 gradually decreases from top to bottom. The material is fed into the housing 1 from the feed hopper 5, and then mixed under the stirring of the stirring blades 3 and continuously conveyed towards the combined discharge structure, and finally discharged to achieve material discharge.

[0028] like Figure 2 and Figure 3 As shown, the combined discharge structure includes a main discharge port 6 and a secondary discharge port 7. A baffle plate 8 is provided on the bottom wall of the shell 1 near the main discharge port 6. The baffle plate 8 is used to prevent materials from being discharged directly from the main discharge port 6. The height of the baffle plate 8 is about one-quarter of the total height of the shell 1. The secondary discharge port 7 is opened on the bottom wall of the shell 1 and is close to the baffle plate 8. The secondary discharge port 7 is located on the side of the baffle plate 8 facing away from the main discharge port 6. The diameter of the secondary discharge port 7 is much smaller than the diameter of the main discharge port 6. In actual use, the baffle plate 8 on the shell 1 can partially prevent materials from being discharged directly from the main discharge port 6. The material being blocked by the baffle plate 8 can prolong its stirring and mixing time in the shell 1, improve the uniformity and thoroughness of mixing. Only when the height of the material is higher than the baffle plate 8 will it be discharged from the main discharge port in large quantities. During the stirring, some of the mixed material can be discharged from the secondary discharge port 7. After the mixing is completed, the material in the shell 1 can be completely discharged with the help of the secondary discharge port 7 to avoid the situation where material remains in the shell 1.

[0029] like Figure 2 and Figure 3 As shown, a protruding discharge connector 9 is provided at the bottom of the housing 1 corresponding to the discharge point. The discharge connector 9 has an outlet 10 for discharging material. At the same time, a reserved mounting hole 11 is provided on the periphery of the discharge connector 9. The discharge connector 9 facilitates subsequent connection and installation with other discharge mechanisms. The main discharge port 6 and the secondary discharge port 7 are both located inside the outlet 10. In this way, the external discharge structure only needs to be connected to the outlet 10 during use, which improves the integration of the discharge structure and facilitates unified external discharge.

[0030] like Figures 1-3 As shown, the stirring blades 3 and the stirring roller 2 are detachably connected, specifically by screws. Multiple stirring blades 3 are distributed at intervals along the circumference of the stirring roller 2, and the angles of each stirring blade 3 are different. At the same time, the angles of adjacent stirring blades 3 in the circumferential direction are also different, which can effectively improve the uniformity and thoroughness of the mixing of materials.

[0031] like Figures 1-2 As shown, the drive assembly includes a drive motor 12 and a reducer 13. The output end of the drive motor 12 is connected to the input end of the reducer 13, and the output end of the reducer 13 is connected to the stirring roller 2, thereby driving the stirring roller 2 to rotate to achieve stirring and mixing. In addition, a mounting base for mounting and fixing the drive assembly is fixedly provided on one side of the housing 1.

[0032] like Figure 1 As shown, a vertical through-slot 14 is opened on the top of the housing 1. The through-slots 14 are spaced apart along the length of the housing 1, and each through-slot 14 is covered by a cover plate 15. The cover plate 15 is used to close the through-slot 14. The cover plate 15 has a handle 16. The cover plate 15 is connected to the housing 1 by screws to make it detachable. With the design of the through-slot 14, it is easy to observe the internal condition of the inner housing 1 or to carry out corresponding inspection and maintenance after opening the cover plate 15.

[0033] like Figures 1-3 As shown, symmetrical support feet 17 are provided at the bottom of the housing 1. The outer side wall of the housing 1 has a reinforcing strip 18 extending along the axial direction. The top of the support foot 17 is fixed to the bottom of the reinforcing strip 18. In addition, reinforcing ribs 19 are provided on the end walls of both ends of the housing 1. This effectively improves the overall structural strength of the housing 1, and the support feet 17 can provide stable and good support.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
