Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and more specifically, to a conical spiral mixer. Background Technology

[0002] As an important type of industrial equipment, a mixer is used to uniformly mix two or more materials using mechanical force and gravity. During the mixing process, it can not only increase the contact surface area of ​​the materials and promote chemical reactions, but also accelerate physical changes. Currently, there are many types of mixers on the market. Among them, the conical spiral mixer has been widely used in the chemical, pharmaceutical, and food industries due to its unique structure and good mixing effect.

[0003] However, existing mechanisms generally use a combination of long and short screws to achieve material convection. In actual use, it has been found that material in the middle is still difficult to enter the convection, resulting in uneven mixing of materials.

[0004] A search revealed that Chinese patent CN221182474U discloses a double-helix conical mixer. In this structure, the mixing conical drum has a cone-shaped design, wider at the top and narrower at the bottom. After the drug is added, it contracts and gathers downwards due to the drum's confinement. Then, it is stirred by long and short mixing screws, which are tilted and adapted to the drum's cone angle, achieving convective mixing. The axis of the turbulence screw at the bottom of the long mixing screw forms an angle with the axis of the long mixing screw. One end of the turbulence screw is attached to a magnet via a magnetic ball head, and the other end is rotatably connected to the long mixing screw. During rotation, the impact of the material causes the angle of the turbulence screw to change, making the mixing more complex and directly affecting the intermediate material, enhancing convection and turbulence effects. The top of the mixing conical drum has an inlet and an outlet for easy material input and output, improving processing efficiency.

[0005] However, in actual use, although the turbulence screw can enhance the turbulence through angle changes, it mainly targets the middle material and has limited effect on the material at the edge or attached to the barrel wall, resulting in low mixing uniformity and long mixing time. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a conical spiral mixer to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A conical spiral mixer includes a conical shell, with two feed frames extending through the top of the conical shell, a discharge pipe extending through the bottom of the conical shell, and a mixing mechanism disposed inside the conical shell;

[0009] The mixing mechanism includes a stepper motor fixedly installed on the top of the conical housing. A rotating shaft is fixedly provided at the output end of the stepper motor. Multiple U-shaped stirring rods are fixedly provided on the surface of the rotating shaft. Multiple connecting rods are fixedly provided between the U-shaped stirring rods and the rotating shaft. Multiple stirring bars are fixedly provided on the surface of the connecting rods.

[0010] A connecting long plate is fixedly installed at one end of the U-shaped stirring rod, a fixing strip is fixedly installed on one side of the connecting long plate, a connecting short plate is fixedly installed on the surface of the rotating shaft, and a scraper strip is fixedly installed between the fixing strip and the connecting short plate.

[0011] By adopting the above technical solution, multi-angle stirring is achieved, greatly improving mixing efficiency. Moreover, the scraper strips are closely attached to the inner wall of the conical shell, which promptly removes the attached material and avoids residue affecting the mixing quality. Secondly, it prevents the discharge pipe from getting blocked, while also helping the material to be discharged smoothly, ensuring uniform and efficient mixing, and meeting the mixing needs of diverse materials.

[0012] As a further description of the above technical solution: a support plate is rotatably provided on the surface of the rotating shaft, both ends of the support plate are connected to the inner wall of the conical shell, and one end of the rotating shaft extends into the discharge pipe;

[0013] A spiral plate is fixedly provided on the surface of the rotating shaft, and multiple L-shaped stirring columns are fixedly provided on the surface of the U-shaped stirring rod;

[0014] The scraper strip is fitted to the inner wall of the conical shell, and a valve is fixedly installed on one side of the discharge pipe.

[0015] By adopting the above technical solutions: ensuring stable operation of the mixing process, the spiral plate combined with the L-shaped mixing column enhances material circulation and mixing intensity, improves mixing uniformity, the scraper strips are closely attached to the inner wall to prevent material residue, and the discharge pipe valve precisely controls the discharge.

[0016] As a further description of the above technical solution: the inside of the feeding frame is provided with a feeding mechanism, the feeding mechanism includes a small motor fixedly installed on one side of the feeding frame, the output end of the small motor is fixedly provided with a rotating rod, and the surface of the rotating rod is fixedly provided with multiple stirring blades;

[0017] The top of the feeding frame is provided with a feeding hopper, and the top of the feeding hopper is hinged with a sealing cover. A handle is fixedly provided on one side of the sealing cover.

[0018] By adopting the above technical solutions, it is not only convenient to quickly feed materials, but also to prevent dust from overflowing during equipment operation, ensuring a clean production environment. The handle on the sealing cover is easy to open and close flexibly, and the feeding mechanism can adjust the speed according to the characteristics of the materials, adapting to different types of materials and enhancing the practicality and versatility of the equipment.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1. By setting up a mixing mechanism, compared with the existing technology, the spiral plate on the surface of the rotating shaft not only pushes the material up and down in the discharge pipe to achieve circulation mixing when it rotates, but also effectively prevents the discharge pipe from being blocked, ensuring that the mixing process is smooth. Moreover, the connecting rod between the U-shaped stirring rod and the rotating shaft, the stirring rod, and the L-shaped stirring column on the U-shaped stirring rod enhance the stirring force from multiple angles and directions, greatly improving the uniformity of material mixing and increasing the mixing efficiency. Secondly, the scraper strip is in close contact with the inner wall of the conical shell, which can scrape off the attached material in time to avoid residues that affect the mixing quality. The support plate provides stable support for the rotating shaft, ensuring the stability of equipment operation. In addition, after mixing, the spiral plate, in conjunction with the gravity of the material, helps the material to be discharged smoothly through the discharge pipe. The entire mixing process is efficient, stable, and practical.

[0021] 2. By setting up a feeding mechanism, compared with the existing technology, after connecting the small motor and stepper motor to an external power source, the material can be easily poured in by operating the handle of the sealing cover to open the feeding hopper. The small motor on one side of the feeding frame drives the rotating rod to rotate, which drives the stirring blade to perform preliminary stirring of the material. This allows the material to reach a pre-mixed state before entering the conical shell, effectively reducing the subsequent mixing time and improving the overall mixing efficiency. This pre-mixing allows the material to be more evenly distributed when entering the mixing mechanism, maximizing the stirring effect of the U-shaped stirring rod, stirring bar and other components, and providing a stable and efficient pre-mixing guarantee for the mixing work.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The embodiments disclosed in this application are as follows: Figure 1-5 A conical spiral mixer includes a conical shell 1, two feed frames 2 are provided through the top of the conical shell 1, a discharge pipe 3 is provided through the bottom of the conical shell 1, and a mixing mechanism is provided inside the conical shell 1.

[0030] The mixing mechanism includes a stepper motor 4 fixedly installed on the top of the conical housing 1. A rotating shaft 5 is fixedly installed at the output end of the stepper motor 4. Multiple U-shaped stirring rods 6 are fixedly installed on the surface of the rotating shaft 5. Multiple connecting rods 7 are fixedly installed between the U-shaped stirring rods 6 and the rotating shaft 5. Multiple stirring rods 8 are fixedly installed on the surface of the connecting rods 7.

[0031] A connecting long plate 9 is fixedly installed at one end of the U-shaped stirring rod 6, a fixing strip 10 is fixedly installed on one side of the connecting long plate 9, a connecting short plate 11 is fixedly installed on the surface of the rotating shaft 5, and a scraper strip 12 is fixedly installed between the fixing strip 10 and the connecting short plate 11.

[0032] Next, the stepper motor 4, which is fixedly installed on the top of the conical shell 1, is started. The stepper motor 4 drives the rotating shaft 5 at the output end to rotate. When the rotating shaft 5 rotates, the multiple U-shaped stirring rods 6 fixed on its surface move accordingly. The multiple connecting rods 7 between the U-shaped stirring rods 6 and the rotating shaft 5, as well as the stirring rods 8 on the surface of the connecting rods 7, work together to stir the material from multiple angles and directions, thereby enhancing the mixing effect.

[0033] Meanwhile, the spiral plate 14 fixed on the surface of the rotating shaft 5 pushes the material up and down inside the discharge pipe 3 during rotation, realizing the circulation and mixing of the material and effectively preventing the discharge pipe 3 from being blocked. The multiple L-shaped stirring columns 15 on the surface of the U-shaped stirring rod 6 further increase the stirring force on the material, making the material mix more evenly.

[0034] Reference Figure 2-3 As shown, a support plate 13 is rotatably mounted on the surface of the rotating shaft 5. Both ends of the support plate 13 are connected to the inner wall of the conical shell 1, and one end of the rotating shaft 5 extends into the discharge pipe 3.

[0035] A spiral plate 14 is fixedly installed on the surface of the rotating shaft 5, and multiple L-shaped stirring columns 15 are fixedly installed on the surface of the U-shaped stirring rod 6;

[0036] The scraper strip 12 is attached to the inner wall of the conical shell 1, and a valve 22 is fixedly installed on one side of the discharge pipe 3;

[0037] As the rotating shaft 5 rotates, the connecting long plate 9 at one end of the U-shaped stirring rod 6 drives the fixed strip 10 to move. The scraper strip 12 between the fixed strip 10 and the connecting short plate 11 on the surface of the rotating shaft 5 fits against the inner wall of the conical shell 1, scraping off the material adhering to the inner wall of the conical shell 1 so that it can re-participate in the mixing and avoid material residue affecting the mixing effect. The support plate 13 rotatably set on the surface of the rotating shaft 5 is connected to the inner wall of the conical shell 1 at both ends, providing stable support for the rotating shaft 5 and ensuring that the mixing process is stable. One end of the rotating shaft 5 extends into the discharge pipe 3, which helps to push the mixed material into the discharge pipe 3. When the material is mixed, the valve 22 on one side of the discharge pipe 3 is opened. Under the push of the spiral plate 14 and the action of the material's own gravity, the uniformly mixed material is discharged from the conical spiral mixer through the discharge pipe 3, completing the entire mixing process.

[0038] Reference Figure 4-5 As shown, the inside of the feed frame 2 is provided with a feeding mechanism, which includes a small motor 16 fixedly installed on one side of the feed frame 2. A rotating rod 17 is fixedly installed at the output end of the small motor 16, and multiple stirring blades 18 are fixedly installed on the surface of the rotating rod 17.

[0039] A feeding hopper 19 is provided through the top of the feeding frame 2, and a sealing cover 20 is hinged to the top of the feeding hopper 19. A handle 21 is fixedly provided on one side of the sealing cover 20.

[0040] Connect the small motor 16 and the stepper motor 4 to an external power source, then open the sealing cover 20 on the top of the feed hopper 19. It is more convenient to operate through the handle 21. Pour the mixture into the feed hopper 19, and the material enters the conical shell 1 through the feed frame 2.

[0041] At the same time, the small motor 16 on one side of the feed frame 2 is started. The small motor 16 drives the rotating rod 17 at the output end to rotate. The multiple stirring blades 18 on the surface of the rotating rod 17 rotate accordingly, and the material is initially stirred before entering the conical shell 1, so that the material has a certain pre-mixing effect before entering the mixing stage.

[0042] Working principle of this utility model:

[0043] This utility model is a conical spiral mixer. When using the device, the small motor 16 and the stepper motor 4 are connected to an external power source. Then, the sealing cover 20 on the top of the feed hopper 19 is opened. The operation is convenient through the handle 21. The materials to be mixed are poured into the feed hopper 19, and the materials enter the conical shell 1 through the feed frame 2.

[0044] At the same time, the small motor 16 on one side of the feed box 2 is started. The small motor 16 drives the rotating rod 17 at the output end to rotate. The multiple stirring blades 18 on the surface of the rotating rod 17 rotate accordingly, and the material is initially stirred before entering the conical shell 1, so that the material has a certain pre-mixing effect before entering the mixing stage.

[0045] Next, the stepper motor 4, which is fixedly installed on the top of the conical shell 1, is started. The stepper motor 4 drives the rotating shaft 5 at the output end to rotate. When the rotating shaft 5 rotates, the multiple U-shaped stirring rods 6 fixed on its surface move accordingly. The multiple connecting rods 7 between the U-shaped stirring rods 6 and the rotating shaft 5, as well as the stirring rods 8 on the surface of the connecting rods 7, work together to stir the material from multiple angles and directions, thereby enhancing the mixing effect.

[0046] Meanwhile, the spiral plate 14 fixed on the surface of the rotating shaft 5 pushes the material up and down inside the discharge pipe 3 during rotation, realizing the circulation and mixing of the material, and effectively preventing the discharge pipe 3 from being blocked. The multiple L-shaped stirring columns 15 on the surface of the U-shaped stirring rod 6 further increase the stirring force on the material, making the material mix more evenly.

[0047] Furthermore, as the rotating shaft 5 rotates, the connecting long plate 9 at one end of the U-shaped stirring rod 6 drives the fixed strip 10 to move. The scraper strip 12 between the fixed strip 10 and the connecting short plate 11 on the surface of the rotating shaft 5 fits against the inner wall of the conical shell 1, scraping off the material adhering to the inner wall of the conical shell 1 so that it can re-participate in the mixing, avoiding material residue from affecting the mixing effect. The support plate 13 rotatably set on the surface of the rotating shaft 5 is connected to the inner wall of the conical shell 1 at both ends, providing stable support for the rotating shaft 5 and ensuring that the mixing process proceeds stably. Moreover, one end of the rotating shaft 5 extends into the discharge pipe 3, which helps to push the mixed material into the discharge pipe 3.

[0048] Once the materials are mixed, open valve 22 on one side of discharge pipe 3. Under the push of spiral plate 14 and the force of the material's own gravity, the uniformly mixed material is discharged from the conical spiral mixer through discharge pipe 3, completing the entire mixing process.

[0049] 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.
