Description

Technical Field

[0001] This utility model belongs to the field of stirring technology, and in particular relates to an assembled stirring head. Background Technology

[0002] With the rapid development of industrial automation, precision manufacturing, and intelligent manufacturing technologies, mixing equipment is increasingly widely used in chemical, food, pharmaceutical, new energy, building materials, and daily chemical industries, leading to ever-increasing demands for mixing efficiency, uniformity, and cleanliness. As the core component of a mixing device, the mixing head's structural design directly determines the material dispersion effect, energy consumption level, and the continuity and hygiene standards of the production process.

[0003] However, most mixing heads on the market today have a simple structure and limited functions, making them difficult to adapt to complex working conditions. When processing high-viscosity, easily agglomerated, or highly adhesive materials, the materials easily adhere to the inner wall of the mixing tank, resulting in material waste and affecting product uniformity. To clean the material adhering to the inner wall, frequent shutdowns are required to arrange for personnel to clean, increasing labor costs. Furthermore, although some mixing heads have a wall scraping structure, the scraper position is fixed and cannot be adapted to mixing tanks of different radii, resulting in gaps between the scraper and the tank wall, poor fit, poor cleaning effect, and many dead corners, making it difficult to completely solve the adhesion problem.

[0004] Therefore, there is a particular need for an assembled stirring head to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing stirring heads, such as simple structure, non-adjustable wall scraping, easy material adhesion, incomplete cleaning, and poor adaptability, this utility model provides an assembled stirring head.

[0006] This utility model is achieved through the following technical means: an assembled stirring head, including a connecting shaft, a connecting flange, a connecting block, and a stirring paddle. A connecting flange is installed at one end of the connecting shaft, and two connecting blocks arranged side by side are fixed to both ends of the connecting shaft. A stirring paddle is fixed between the two staggered connecting blocks. The stirring paddle is shaped like a spiral blade. It also includes a sliding block, a scraper, a bidirectional lead screw, a dual-axis motor, a connecting rod, a first bevel gear, and a second bevel gear. A sliding block is slidably arranged inside each connecting block. A scraper is installed between two vertically aligned sliding blocks. The two scrapers are in a opposing state with their scraping surfaces facing outwards. A bidirectional lead screw is rotatably arranged at both ends of the connecting shaft. The bidirectional lead screw passes through the corresponding sliding block and is threadedly engaged with it. A dual-axis motor is installed in the hollow cavity inside the connecting shaft. The two output shafts of the dual-axis motor extend upwards and downwards respectively, and a connecting rod is fixed to each output shaft. A first bevel gear is fixed to the end of each of the two connecting rods. A second bevel gear is fixed to the outside of each bidirectional lead screw. The second bevel gear meshes with the corresponding first bevel gear.

[0007] In one embodiment, the device further includes a connecting cylinder and a stirring plate. Multiple connecting cylinders are equidistantly distributed along the height direction on the outside of the connecting shaft, and two symmetrically arranged stirring plates are rotatably mounted on each connecting cylinder.

[0008] In one embodiment, a rotating plate is also included, with the other end of the connecting shaft mounted on the rotating plate.

[0009] In one embodiment, the scraper also includes a rotating shaft and a flap, with a rotating shaft rotatably mounted on each scraper and a flap fixed to the outside of each rotating shaft.

[0010] In one embodiment, the two stirring blades are intertwined in space, forming a double helix structure.

[0011] In one embodiment, the edges of the stirring plate, rotating plate, and flip plate are all designed with a cutting edge structure.

[0012] Beneficial effects: 1. Through the cooperation of sliding block, scraper, bidirectional lead screw, dual-shaft motor, connecting rod, first bevel gear and second bevel gear, the position of scraper can be electrically adjusted and adaptively extended and retracted, which can be adapted to mixing tanks with different inner diameters, ensuring that the scraper is in close contact with the inner wall of the mixing tank, significantly improving the wall cleaning effect, reducing material residue, and reducing the frequency of manual cleaning.

[0013] 2. By setting up the connecting cylinder and stirring plate, the disturbance ability of materials in the upper, middle and lower layers of the mixing tank is enhanced, the mixing coverage is expanded, and the mixing efficiency and uniformity are improved.

[0014] 3. The rotating plate helps to agitate the material at the bottom of the mixing tank, effectively preventing high-viscosity or heavy materials from settling at the bottom and further improving the overall mixing uniformity.

[0015] 4. By using the rotating shaft and the flap, the material can be agitated during the rotation of the scraper, which enhances the local mixing effect and improves the overall fluidity of the material. Attached Figure Description

Detailed Implementation

[0021] Example: An assembled stirring head, such as Figures 1-4 As shown, it includes a connecting shaft 1, a connecting flange 2, a connecting block 3, and a stirring paddle 4. The connecting flange 2 is bolted to the upper end of the connecting shaft 1 to connect to the drive end of the stirring device. Two connecting blocks 3 are fixedly connected to both the upper and lower ends of the connecting shaft 1, arranged side by side. A stirring paddle 4 is fixedly connected between the two staggered connecting blocks 3 (i.e., upper left and lower right, or upper right and lower left). The stirring paddle 4 is shaped like a spiral blade and generates a strong shearing force on the material when it rotates with the connecting shaft 1, achieving efficient stirring. The two stirring paddles 4 are distributed in a cross-shaped manner in space, intertwining to form a double spiral structure. This structure can maximize the use of the stirring space in a limited space, enhance shearing and circulation capabilities, and is suitable for efficient dispersion and homogenization of high-viscosity materials. It also includes a sliding block 8, a scraper 9, a bidirectional lead screw 12, a dual-shaft motor 13, a connecting rod 131, a first bevel gear 14, and a second bevel gear 15. Inside each connecting block 3, a sliding block 8 is slidably arranged. A scraper 9 is bolted between two vertically aligned sliding blocks 8. The two scrapers 9 are in a opposing state, with their scraping surfaces facing outwards, and can respectively face the inner walls of the left and right sides of the mixing tank. A bidirectional lead screw 12 is rotatably arranged at both the upper and lower ends of the connecting shaft 1. The bidirectional lead screw 12 passes through the corresponding sliding block 8 and is threaded with it to realize the synchronous extension and retraction of the sliding block 8. A dual-axis motor 13 is bolted to the hollow cavity inside the connecting shaft 1. The two output shafts of the dual-axis motor 13 extend upwards and downwards respectively, and each output shaft is fixedly connected to a connecting rod 131 through a coupling. A first bevel gear 14 is fixedly connected to the end of each of the two connecting rods 131. A second bevel gear 15 is fixedly connected to the outside of each bidirectional lead screw 12. The second bevel gear 15 meshes with the corresponding first bevel gear 14 to form a power transmission system.

[0022] like Figures 1-4As shown, the connecting cylinder 5, stirring plate 6, rotating plate 7, rotating shaft 10, and flap 11 are connected to the outside of the connecting shaft 1 by bolts. Three connecting cylinders 5 are equidistantly distributed along the height direction. Two symmetrically arranged stirring plates 6 are rotatably mounted on each connecting cylinder 5. The rotating plate 7 is bolted to the lower end of the connecting shaft 1. A rotating shaft 10 is rotatably mounted on each scraper 9. A flap 11 is fixedly connected to the outside of each rotating shaft 10. The flap 11 can be passively rotated under the resistance of the material to achieve the stirring of the material. The edges of the stirring plate 6, rotating plate 7, and flap 11 are all designed with a cutting edge structure to enhance the cutting, stirring, and scraping capabilities, and work together with the stirring paddle 4 to achieve multi-level and compound stirring.

[0023] In use, the operator first installs the connecting shaft 1 on the drive end of the stirring device (such as the motor reducer assembly) through the connecting flange 2 to complete the assembly and fixation of the stirring head. Then, the power cord of the dual-shaft motor 13 is connected to the control system of the stirring device to achieve independent power supply and control. Then, the stirring device is installed on the mouth of the mixing tank (the installation method is mostly threaded connection or quick-release clamp connection), so that the stirring head enters the interior of the mixing tank vertically. At this time, the scraper 9 is in the initial retracted state, and its scraping surface is aligned with the inner wall of the mixing tank.

[0024] Next, the dual-shaft motor 13 is started by the control button on the stirring device, which controls its two output shafts to drive the two connecting rods 131 to rotate clockwise. The two connecting rods 131 drive the two first bevel gears 14 to rotate clockwise, and then mesh with the two second bevel gears 15 for transmission. At this time, the two second bevel gears 15 drive the two bidirectional lead screws 12 to rotate counterclockwise, driving the corresponding sliding block 8 to slide outward along the connecting block 3. The sliding block 8 then drives the corresponding scraper 9 to extend outward, so that the scraper 9 gradually approaches the inner wall of the mixing tank. When the scraper 9 slides to contact the inner wall of the mixing tank, the dual-shaft motor 13 is immediately turned off, so as to precisely adjust the radial position of the scraper 9 according to the actual radius of the mixing tank, and realize flexible adaptation to mixing tanks of different radii.

[0025] After adjustment, remove the stirring device, briefly remove the stirring head from the mixing tank, add the material to be stirred into the mixing tank, and then reinstall the stirring device to reset the stirring head into the mixing tank. Then start the drive end of the stirring device to drive the connecting shaft 1 to rotate at high speed. During the rotation, the connecting block 3 drives the stirring paddle 4 and scraper 9 to rotate synchronously. The stirring paddle 4 shears, disperses and propels the high-viscosity material during rotation. The scraper 9 continuously scrapes off the material adhering to the inner wall of the mixing tank to prevent wall sludge and dead corners. At the same time, the connecting shaft 1 drives the stirring plate 6 on the connecting cylinder 5 to disturb and mix the materials in the upper, middle and lower layers of the mixing tank, and drives the rotating plate 7 to stir the bottom material of the mixing tank to prevent sedimentation. When the scraper 9 rotates, it drives the rotating shaft 10 to rotate together, so that the flip plate 11 rotates passively under the resistance of the material to achieve the stirring of the material.

[0026] After mixing is complete, turn off the drive and power, remove the mixing device, lift the mixing head out of the mixing plate 6, and pour out the evenly mixed material inside the mixing tank for subsequent cleaning operations.
