Description

Technical Field

[0001] This utility model relates to the field of mixing technology, and in particular to a mixing device. Background Technology

[0002] A mixing device is a piece of equipment used to mix different materials. It typically consists of a stirrer, a container, and a drive system. Mixing devices are widely used in chemical, pharmaceutical, food processing, and agricultural fields to uniformly mix different granular, powdered, or liquid materials to achieve a thorough mixing effect. In pharmaceutical production, mixers are frequently used, for example, to mix raw materials for pharmaceuticals.

[0003] Most existing mixers are cylindrical, and are combined with agitators to mix materials. For example, Chinese patent CN201922239082.6 discloses a mixing device for chemical and pharmaceutical production. It is equipped with a stirring component. The stirring motor drives the first and second scrapers through the stirring shaft to clean the inner wall of the shell, which is convenient for cleaning. Compared with manual cleaning, the operation is more time-saving and labor-saving, reducing the labor intensity of workers. In addition, the setting of a fixed frame component improves the stability of the mixing equipment, enhances the safety of the mixing process, and is easy to install, bringing great convenience to users.

[0004] However, in the aforementioned patent, the shell is in a static state, and the position of the stirring component is relatively fixed. It can only uniformly mix the raw materials that are at the same level as the stirring rod. The raw materials at the bottom and the raw materials at the top are difficult to come into contact and mix, resulting in poor uniformity of mixing of the raw materials and poor stirring quality. Utility Model Content

[0005] One object of this invention is to solve at least the aforementioned problems and / or defects, and to provide at least the advantages described below.

[0006] To address the shortcomings of existing technologies, this utility model provides a mixing device, comprising:

[0007] The main body is horizontally arranged on an inclined base and parallel to the inclined surface of the base; the main body includes a cylindrical body and a pair of sealing plates fixed on the base, the cylindrical body is rotatably arranged between the sealing plates, and the cylindrical body has a feed inlet and a discharge outlet.

[0008] A central cylinder is coaxially disposed inside the cylinder body; one end of the central cylinder is fixed to a sealing plate, and the other end of the central cylinder has a material discharge gap with the sealing plate, and the surface of the central cylinder has a through hole; a conveying auger is coaxially disposed inside the central cylinder, and one end of the conveying auger is connected to a rotating shaft driven by a drive assembly.

[0009] The stirring assembly includes a vertical plate and a plurality of stirring rods surrounding the central cylinder; the vertical plate is fixed on the rotating shaft and rotatably connected to the sealing plate, and a transmission cavity is formed between the vertical plate and the sealing plate; the stirring rods are rotatably mounted on the vertical plate and extend into the transmission cavity and are connected to the transmission mechanism, driving the stirring rods to rotate around the central cylinder while rotating on their own axis.

[0010] The sealing plate has an annular groove facing the side of the cylinder, and the rotating parts at both ends of the cylinder are located in the annular groove.

[0011] The drive assembly includes a first motor, which is fixed on the base and the output shaft of the first motor is connected to the rotating shaft.

[0012] A toothed ring is fixed to the outer surface of the cylinder, a second motor is fixed to the base, and a first gear is fixed to the output shaft of the second motor. The first gear meshes with the toothed ring.

[0013] A support frame is fixed on the base, and the top surface of the support frame has a support groove that slides in contact with the cylinder.

[0014] The through hole is located on the upper surface of one end of the central cylinder.

[0015] A scraper is fixed on the sealing plate, and the scraper is in contact with the inner wall of the cylinder.

[0016] The transmission mechanism includes a gear ring fixed on the sealing plate, and a second gear is fixed at one end of the stirring rod located in the transmission cavity. The second gear meshes with the gear ring.

[0017] The stirring rod is equipped with an arc-shaped lifting plate.

[0018] This utility model has at least the following beneficial effects: The main body of this utility model provides a mixing environment, and the sealing plate serves to enclose the cylinder while also supporting its movement; the horizontal arrangement of the main body and the rotatable arrangement of the cylinder allow the material to move with the rotation of the cylinder, thereby allowing the material at the bottom to move to the top, enhancing the material's movement and dispersion effect, and promoting the contact and mixing between materials; the central cylinder, in conjunction with the rotating conveyor auger, transports the raw materials falling into the central cylinder to the other end of the central cylinder, allowing materials at different positions in the cylinder to move and fully contact and mix with materials at other positions, effectively enhancing the uniformity of mixing; simultaneously, the vertical plate is fixed on the rotating shaft, and the rotation of the shaft drives the vertical plate to rotate, thereby driving the stirring rod to rotate and mix the material. Under the action of the transmission mechanism, the stirring rod can rotate on its own axis while rotating with the vertical plate, further promoting the material movement and improving the mixing effect; the vertical plate, on the one hand, drives the stirring rod to rotate, and on the other hand, prevents material from entering the transmission cavity.

[0019] Using this invention, the material tumbles continuously inside the cylinder as the cylinder rotates. During the material feeding process from the bottom to the top, it falls into the central cylinder. Under the action of the conveying auger, the material moves from one end of the central cylinder to the other, thereby realizing the mutual mixing movement of the material between the two ends of the cylinder. This allows the material inside the cylinder to move around, further improving the mixing efficiency. At the same time, the stirring rod rotates around the central cylinder while also rotating on its own axis, thus fully and comprehensively mixing the materials, enhancing the mixing effect, and making the materials evenly and thoroughly mixed.

[0026] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0027] See Figures 1 to 4 A mixing device, comprising:

[0028] The body 100 provides a mixing environment and is horizontally mounted on an inclined base 200, parallel to the inclined surface of the base 200. The axis of the body 100 is parallel to the inclined surface of the upper surface of the base 200. The body 100 includes a cylindrical body 110 and a pair of sealing plates 120 fixed to the base 200. The cylindrical body 110 is rotatably disposed between the sealing plates 120, which serve to seal the cylindrical body 110 and support its movement. Specifically, the sealing plates 120 have annular grooves 122 on their sides facing the cylindrical body 110, and rotating parts 1 at both ends of the cylindrical body... 12 is located within the annular groove 122. The annular groove 122 cooperates with the rotating part 112 to allow the cylinder 110 to rotate relative to the sealing plate 120. A sealing bearing can be provided between the annular groove 122 and the rotating part 112. The sealing bearing is a prior art product. The cylinder 110 has an inlet 113 and an outlet 114. Both the inlet 113 and the outlet 114 are normally closed. After mixing is completed, the outlet 114 can be opened to discharge the material inside the cylinder 110. It is worth noting that the outlet 114 is located at the lower end of the inclined direction of the cylinder 110 to facilitate the smooth discharge of the material.

[0029] A central cylinder 300 is coaxially disposed within the cylinder body 110 and is fixed in place. One end of the central cylinder 300 is fixed to a sealing plate 120, and the other end has a material discharge gap 320 with the sealing plate 120. The surface of the central cylinder 300 has a through hole 310 for material to enter into the central cylinder 300, and the material discharge gap 320 for material to fall out of the central cylinder 300. A conveying auger 330 is coaxially disposed inside the central cylinder 300. The conveying auger 330 is a prior art product, and one end of the conveying auger 330 is connected to a rotating shaft 400 driven by a drive assembly 410.

[0030] The stirring assembly 500 includes a vertical plate 510 and a plurality of stirring rods 520 surrounding the central cylinder 300. The vertical plate 510 is fixed on the rotating shaft 400 and rotatably connected to the sealing plate 120. A transmission cavity 121 is formed between the vertical plate 510 and the sealing plate 120. The stirring rods 520 are rotatably mounted on the vertical plate 510 and extend into the transmission cavity 121 and are connected to the transmission mechanism 600. The stirring rods 520 are driven to rotate around the central cylinder 300 while rotating on their own axis. The vertical plate 510 serves to drive the stirring rods 520 to rotate while preventing material from entering the transmission cavity 121.

[0031] Specifically, the rotatable design of the cylinder 110 allows the material inside the cylinder 110 to move with the rotation of the cylinder 110, thereby allowing the material at the bottom to move to the top, enhancing the material's movement and dispersion effect, and promoting the contact and mixing between materials. The central cylinder 300, in conjunction with the rotating conveying auger 330, transports the raw materials falling into the central cylinder 300 to the other end of the central cylinder 300, so that materials at different positions in the cylinder 110 can move and fully contact and mix with materials at other positions, effectively enhancing the mixing uniformity. At the same time, the vertical plate 510 is fixed on the rotating shaft 400. The rotation of the rotating shaft 400 drives the vertical plate 510 to rotate, thereby driving the stirring rod 520 to rotate and mix the material. Under the action of the transmission mechanism 600, the stirring rod 520 can rotate on its own axis while rotating with the vertical plate 510, further promoting the movement of materials and improving the mixing effect.

[0032] Based on the above, in some embodiments, the drive assembly 410 includes a first motor 411, which is fixed on the base 200, and the output shaft of the first motor 411 is connected to the rotating shaft 400. The first motor 411 is a prior art product. In specific use, the first motor 411 drives the rotating shaft 400 to rotate, and the rotating shaft 400 drives the conveying auger 330 and the vertical plate 510 to rotate.

[0033] Based on the above, in some embodiments, a gear ring 710 is fixed to the outer surface of the cylinder 110, a second motor 700 is fixed to the base 200, and a first gear 720 is fixed to the output shaft of the second motor 700. The first gear 720 meshes with the gear ring 710. With this design, the second motor 700 drives the first gear 720 to rotate, and the engagement of the first gear 720 with the gear ring 710 causes the gear ring 710 to rotate. Furthermore, a support frame 210 is fixed to the base 200. The top surface of the support frame 210 has a support groove 211 that slides in contact with the cylinder 110. The support frame 210 further enhances the supporting force, thereby improving the stability of the cylinder 110 and ensuring smooth and safe rotation of the cylinder 110.

[0034] Based on the above, in some embodiments, the through hole 310 is located on the upper surface of one end of the central cylinder 300. During the falling process, the material can enter the central cylinder 300 through the through hole 310, and then move to the other end under the conveying auger 330 and fall back into the cylinder 110 through the material drop gap 320. Then, under the guidance of the inclined cylinder 110 and the action of the stirring rod 520, it can be fully mixed with the material in other positions. By adopting this scheme, excessive accumulation of material at one end of the cylinder 110 can be avoided.

[0035] Based on the above, in some embodiments, to avoid excessive material adhering to the inner wall of the cylinder 110, causing waste and affecting the mixing effect of the next batch, a scraper 800 is fixed on the sealing plate 120, and the scraper 800 contacts the inner wall of the cylinder 110. With this solution, the scraper 800 remains stationary, and when the cylinder 110 rotates, it contacts the scraper 800, thus scraping off the material adhering to the inner wall of the cylinder 110.

[0036] Based on the above, in some embodiments, the transmission mechanism 600 includes a gear ring 610 fixed on the sealing plate 120, and a second gear 521 is fixed at one end of the stirring rod 520 located in the transmission cavity 121, the second gear 521 meshing with the gear ring 610. With this design, the second gear 521, in cooperation with the gear ring 610, causes the stirring rod 520 to rotate simultaneously with the vertical plate 510, further improving mixing efficiency.

[0037] Based on the above, in some embodiments, the stirring rod 520 is provided with an arc-shaped lifting plate 540. The lifting plate 540 further turns the material, so that the material is carried upward and then part of it can enter the central cylinder 300 during the falling process.

[0038] Using this invention, the material inside the cylinder 110 continuously tumbles as the cylinder 110 rotates. The stirring rod 520 stirs and agitates the material. During the material feeding process from the bottom to the top, it falls into the central cylinder 300 through the through hole 310. Under the action of the conveying auger 330, the material moves from one end of the central cylinder 300 to the other end and finally falls back into the cylinder 110 through the material drop gap 320. This achieves mutual mixing of the material between one end and the other end of the cylinder 110, allowing the material inside the cylinder 110 to move around, further improving the mixing efficiency. At the same time, the stirring rod 520 rotates around the central cylinder 300 while also rotating on its own axis, thus fully and comprehensively stirring the mixed materials, enhancing the mixing effect, and making the materials mixed evenly and thoroughly.

[0039] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and illustrations shown and described herein. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from the spirit and scope of this utility model.
