Description

Technical Field

[0001] This utility model relates to the field of mechanical mixing technology, and in particular to a mixer with bidirectional mixing function. Background Technology

[0002] In many industries such as chemical, food, and pharmaceutical, mixing machines are key equipment for mixing materials, and their mixing effect directly determines the uniformity and quality of the final product.

[0003] Most existing mixers use a unidirectional stirring method. For viscous materials or materials with large density differences, unidirectional stirring can easily create mixing dead zones, and material residue is easily left at the bottom of the cylinder. Traditional support structures are prone to uneven wear and vibration during operation.

[0004] Therefore, this utility model proposes a mixer with bidirectional stirring function. Utility Model Content

[0005] Therefore, in order to overcome common problems such as uneven mixing, dead corners, easy material accumulation at the bottom, and unstable cylinder support.

[0006] The technical solution of this utility model is as follows: a mixer with bidirectional mixing function, including a mixing cylinder, a support frame, a mixing component and a rotating component. The support frame is installed on the outside of the mixing cylinder, the mixing component is installed on the upper end of the support frame, and the rotating component is installed between the support frame and the mixing cylinder. The upper wall of the mixing cylinder is provided with a feed port with a threaded sealing cap, and the lower end of the mixing cylinder is provided with a discharge port with a discharge valve.

[0007] Preferably, the mixing assembly includes a first drive motor, a drive shaft, a large spiral ribbon, a stirring blade, a small spiral ribbon, and a spiral blade. A mounting bracket is fixedly installed on the support frame. The first drive motor is fixedly installed on the upper end of the mounting bracket and coaxially connected to the drive shaft. Two sets of the large spiral ribbons are symmetrically fixedly installed on the outer part of the drive shaft. Four sets of stirring blades are evenly distributed along the axial direction of the drive shaft. The small spiral ribbon is located between the stirring blades and the large spiral ribbons and is fixed to the outer wall of the drive shaft. The spiral directions of the large and small spiral ribbons are opposite. A spiral blade is installed at the end of the drive shaft.

[0008] Preferably, a flexible scraper is fixedly provided at the bottom end of the spiral blade, and the shape of the flexible scraper is adapted to the inner wall contour of the mixing cylinder.

[0009] Preferably, a rotating component is fixedly provided at the upper end of the mixing cylinder, and a rotating block is fixedly provided at the lower end of the mounting frame. The rotating component is sleeved on the outer wall of the rotating block, and a self-aligning bearing is installed between the rotating block and the rotating component.

[0010] Preferably, the rotating assembly includes a second drive motor, a main rotating gear, and a driven rotating gear. The second drive motor is fixedly installed on the outer wall of the support frame. The output shaft of the second drive motor is coaxially connected to the main rotating gear. Two sets of driven rotating gears are rotatably installed on the inner wall of the support frame. The outer wall of the mixing cylinder is provided with a gear ring that meshes with the main rotating gear and the driven rotating gear.

[0011] Preferably, the inner wall of the middle part of the support frame is fixedly provided with a shaft slide groove, and a plurality of grooves are opened in the shaft slide groove.

[0012] The beneficial effects of this utility model are: 1. When the mixer is in use, by setting large and small spiral ribbons with opposite spiral directions, strong reverse material convection is formed in the mixing cylinder. At the same time, the rotating component drives the mixing cylinder to rotate, which generates relative motion with the internal agitator, greatly improving the mixing efficiency and uniformity and effectively eliminating mixing dead zones. 2. When in use, the mixer uses a flexible scraper to adaptively scrape off residual material adhering to the inner wall, ensuring the output rate and batch-to-batch cleanliness. The self-aligning bearing limits the swing, and the shaft slide groove and sliding ball keep it aligned and bear the weight, ensuring smooth and stable operation and extending the service life of the equipment.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a mixer with bidirectional mixing function, including a mixing cylinder 1, a support frame 2, a mixing component 3 and a rotating component 4. The support frame 2 is installed on the outside of the mixing cylinder 1, the mixing component 3 is installed on the upper end of the support frame 2, and the rotating component 4 is installed between the support frame 2 and the mixing cylinder 1. The upper wall of the mixing cylinder 1 is provided with a feed port with a threaded sealing cover 101, and the lower end of the mixing cylinder 1 is provided with a discharge port with a discharge valve 102.

[0020] The mixing assembly 3 includes a first drive motor 301, a drive shaft 302, a large spiral ribbon 303, a stirring blade 304, a small spiral ribbon 305, and a spiral blade 306. A mounting frame 201 is fixedly installed on the support frame 2. The first drive motor 301 is fixedly installed on the upper end of the mounting frame 201. The first drive motor 301 is coaxially connected to the drive shaft 302. Two sets of large spiral ribbons 303 are symmetrically fixedly installed on the outer part of the drive shaft 302. Four sets of stirring blades 304 are evenly distributed along the axial direction of the drive shaft 302. The small spiral ribbon 305 is located between the stirring blades 304 and the large spiral ribbons 303 and is fixed to the outer wall of the drive shaft 302. The spiral directions of the large spiral ribbons 303 and the small spiral ribbons 305 are opposite. A spiral blade 306 is installed at the end of the drive shaft 302. The large spiral ribbon 303 and the small spiral ribbon 305 have opposite spiral directions, forming a strong countercurrent material flow inside the cylinder. The stirring plate 304 further shears and diffuses the material, thereby achieving efficient bidirectional stirring.

[0021] A flexible scraper 307 is fixedly provided at the bottom end of the spiral blade 306. The shape of the flexible scraper 307 is adapted to the inner wall contour of the mixing cylinder 1. The flexible scraper 307 here is made of wear-resistant rubber or polyurethane to scrape off the material adhering to the inner wall and prevent material accumulation.

[0022] A rotating component 103 is fixedly installed at the upper end of the mixing cylinder 1, and a rotating block is fixedly installed at the lower end of the mounting frame 201. The rotating component 103 is sleeved on the outer wall of the rotating block, and a self-aligning bearing is installed between the rotating block and the rotating component 103. The self-aligning bearing here can automatically adapt to slight axial misalignment that may be caused by the weight of the cylinder and the load, thereby avoiding additional stress.

[0023] The rotating assembly 4 includes a second drive motor 401, a main rotating gear 402 and a driven rotating gear 403. The second drive motor 401 is fixedly installed on the outer wall of the support frame 2. The output shaft of the second drive motor 401 is coaxially connected to the main rotating gear 402. Two sets of driven rotating gears 403 are rotatably installed on the inner wall of the support frame 2. The outer wall of the mixing cylinder 1 is provided with a gear ring 104 that meshes with the main rotating gear 402 and the driven rotating gear 403. The two sets of rotating gears 403 here ensure the stability of the transmission.

[0024] A shaft slide groove 202 is fixedly provided on the inner wall of the middle part of the support frame 2. Several grooves are opened in the shaft slide groove 202, and several shaft sliding balls 203 are provided in the grooves. The shaft sliding balls 203 roll in contact with the outer wall of the mixing cylinder 1. The several axial sliding balls 203 in the groove here form rolling contact with the outer wall of the mixing cylinder 1, which not only bear most of the weight of the cylinder, but also greatly reduce the frictional resistance, ensuring the flexibility and stability of the rotation of the mixing cylinder 1.

[0025] Working principle: See Figures 1-5 As shown, the operator opens the threaded sealing cover 101 and puts the material to be mixed into the mixing cylinder 1. Then, the first drive motor 301 is started. The first drive motor 301 drives the entire mixing assembly 3 to rotate at high speed through the drive shaft 302. The large spiral ribbon 303 fixed on the outside of the drive shaft 302 and the small spiral ribbon 305 located on the inside have opposite spiral directions. When rotating, they generate opposite thrusts on the material. The large spiral ribbon 303 pushes the material along the cylinder wall in one direction, while the small spiral ribbon 305 pushes the material in the central area back in the opposite direction, forming strong convection shear. At the same time, multiple sets of stirring blades 304 evenly distributed on the drive shaft 302 further impact, disperse and diffuse the passing material.

[0026] See Figures 2-4 As shown, while the internal mixing is underway, the second drive motor 401 starts and drives the gear ring 104 on the outer wall of the mixing cylinder 1 through the main rotating gear 402 on its output shaft, thereby causing the entire mixing cylinder 1 to rotate slowly around its axis. The rotation of the mixing cylinder 1 and the forced flow generated by the internal agitator form a superimposed effect, resulting in uniform mixing.

[0027] See Figures 3-5 As shown, the upper end of the mixing cylinder 1 achieves adaptive positioning through the self-aligning bearing between the rotating part 103 and the rotating block, while the lower end is supported by the shaft slide groove 202 on the support frame 2. The shaft slide ball 203 in the shaft slide groove 202 changes the sliding friction between the mixing cylinder 1 and the support frame 2 into rolling friction, making the rotation of the mixing cylinder 1 easy and smooth, and significantly reducing running wear.

[0028] At the end of the mixing process and during the discharge stage, the spiral blade 306 installed at the end of the drive shaft 302 continuously pushes the material settled at the bottom of the mixing cylinder 1 toward the discharge valve 102 in the center. The flexible scraper 307 fixed at the bottom of the spiral blade 306 is adapted to the inner wall of the bottom of the mixing cylinder 1 to scrape off the residual material adhering to the inner wall, ensuring that the material is discharged completely and without residue.

[0029] It should be noted that the first drive motor 301 and the second drive motor 401 can be powered by existing operating techniques, whether by using a power supply device or by an external wire. These are all conventional operating techniques and will not be described in detail here.

[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
