Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and more specifically, to an anti-deposition structure for a PBT slurry preparation tank. Background Technology

[0002] PBT (polybutylene terephthalate) is a plastic material widely used in engineering, machinery, and daily life. Many decorative materials also use PBT as their main material. Due to factors such as the solids content, particle characteristics, consistency, and viscosity of the slurry, PBT slurry is prone to varying degrees of sedimentation during mixing, affecting the subsequent use of the preparation tank and the homogeneity of the prepared slurry. Existing methods for addressing slurry sedimentation use a single stirring device with a certain rotation frequency to mix the PBT slurry and reduce sedimentation. However, this method makes it difficult to scrape the inner wall of the preparation tank, which is prone to sedimentation, further impacting the tank's usability. Therefore, this paper proposes an anti-settling structure for PBT slurry preparation tanks. Utility Model Content

[0004] To address at least one of the aforementioned problems, this invention first provides an anti-deposition structure for a PBT slurry preparation tank, which can prevent sediment from forming during slurry mixing and remove sediment adhering to the inner wall of the bottom of the preparation tank, thus avoiding adverse effects on the preparation tank.

[0005] (II) Technical Solution

[0006] To solve the aforementioned technical problem, this utility model provides an anti-settling structure for a PBT slurry preparation tank, including a rotating connecting seat, a first mixing device, and a second mixing device. The rotating connecting seat contains a driven pulley, on which a rotating column is mounted. A sun gear is located at the bottom of the rotating column, and a planetary gear is connected to the sun gear. A limiting gear ring is connected to the outer end of the planetary gear, and the limiting gear ring is fixedly mounted on the inner wall of the cover at the top of the preparation tank. The first mixing device is fixedly mounted at the bottom of the sun gear, and the second mixing device is fixedly mounted at the bottom of the planetary gear. A conveyor belt is mounted on the driven pulley, and a driving pulley is located at the other end of the conveyor belt. The driving pulley is fixedly connected to the output shaft of a rotating motor. During mixing, the rotating motor controls the driving pulley to rotate the driven pulley. The driven pulley, through the rotating column, drives the sun gear and the first mixing device to rotate at the same frequency. The planetary gear drives the second mixing device to rotate at the same amplitude as the sun gear, uniformly agitating the raw materials inside the preparation tank.

[0007] Furthermore, the sun gear meshes with the planetary gear, and the planetary gear meshes with the limiting gear ring.

[0008] Furthermore, the outer wall of the limiting gear ring is uniformly provided with a plurality of connecting screw holes.

[0009] Furthermore, the planetary gear has a first connecting end at the center of its top end, a ball socket at the top of the first connecting end, a steering ball head inside the ball socket, an inclined connecting rod on the steering ball head, and a second connecting end at the other end of the inclined connecting rod, which is disposed on the rotating collar.

[0010] Furthermore, the top of the rotating column is provided with an annular groove, and the rotating collar is movably connected to the annular groove.

[0011] Furthermore, the second mixing device includes a second rotating rod, the bottom of which is provided with a connecting frame, the connecting frame being disposed within a mounting base, and the mounting base having a plurality of stirring columns evenly distributed along its edge.

[0015] (III) Beneficial Effects

[0016] This utility model provides an anti-deposition structure for a PBT slurry preparation tank. It includes a first mixing device and a second mixing device controlled by a linkage of a sun gear and planetary gears within the tank. Driven by a rotating motor, these devices agitate the PBT slurry inside the tank.

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] See Figures 1 to 4 This utility model provides an anti-deposition structure for a PBT slurry preparation tank, including a rotating connecting seat 2, a first mixing device 7, and a second mixing device 8. The rotating connecting seat 2 has a driven pulley, a rotating column 3 on the driven pulley, a sun gear 4 at the bottom of the rotating column 3, a planetary gear 6 connected to the sun gear 4, and a limiting gear ring 5 connected to the outer end of the planetary gear 6. The limiting gear ring 5 is fixedly installed on the inner wall of the cover at the top of the preparation tank. The first mixing device 7 is fixedly installed at the bottom of the sun gear 4, and the second mixing device 8 is fixedly installed at the bottom of the planetary gear 6. A conveyor belt is provided on the driven pulley, and a driving pulley is provided at the other end of the conveyor belt. The driving pulley is fixedly connected to the output shaft of a rotating motor. During mixing, the rotating motor controls the driving pulley to drive the driven pulley to rotate. The driven pulley drives the sun gear 4 and the first mixing device 7 to rotate at the same frequency through the rotating column 3. The planetary gear 6 drives the second mixing device 8 to rotate at the same amplitude as the sun gear 4, uniformly stirring the raw materials inside the preparation tank.

[0025] The anti-deposition mechanism in this scheme is installed on the preparation tank. The first mixing device 7 and the second mixing device 8 are placed inside the preparation tank to stir and mix the PBT slurry inside the preparation tank. After the slurry is fully mixed, control pulses are input to the rotating motor to adjust the rotation speed of the first mixing device 7 and the second mixing device 8. The second mixing device 8 mixes the slurry at the upper end of the inner cavity of the preparation tank, and the first mixing device 7 mixes the slurry at the lower end of the inner cavity of the preparation tank. It also scrapes off the deposits on the bottom wall and the lower inner wall of the preparation tank due to gravity. The scraped slurry can be fully mixed and prepared with the upper slurry to ensure the quality of the PBT slurry preparation.

[0026] The conveyor belt and driven pulley are both housed inside the connecting housing 1, and the connecting housing 1 is fixedly connected to the mounting bracket.

[0027] The mixing tank is equipped with an electric lifting component on the mounting frame of the rotating motor. Control commands can be input to activate the electric lifting component to lift the anti-deposition mechanism along with the cover. The cover is disconnected from the mixing tank assembly, which facilitates the maintenance or replacement of the anti-deposition mechanism and also allows for the cleaning of the inner wall of the mixing tank. The prepared slurry is discharged from the discharge port at the bottom of the mixing tank.

[0028] See Figure 1 The sun gear 4 meshes with the planetary gear 6, and the planetary gear 6 meshes with the limiting gear ring 5. The sun gear 4, the planetary gear 6, and the limiting gear ring 5 together form the rotation and speed regulation device used in this scheme. The rotation of the sun gear 4 drives the planetary gear 6 to move in the same direction as the limiting gear ring 5, so that the planetary gear 6 carries the second mixing device 8 around the first mixing device 7 to stir the slurry.

[0029] The outer wall of the limiting gear ring 5 is evenly provided with several connecting screw holes. When the device is installed, the connecting bolts are screwed into the connecting screw holes from the outer end of the cover body to establish a stable installation between the cover body and the limiting gear ring 5. During the operation of the planetary gear 6, the limiting gear ring 5 does not produce displacement, and works with the sun gear 4 to establish stable control of the operation of the planetary gear 6.

[0030] See Figure 2The planetary gear 6 has a first connecting end 61 at the center of its top end. The top of the first connecting end 61 has a ball socket, and a steering ball head 62 is provided inside the ball socket. An inclined connecting rod 63 is provided on the steering ball head 62. The other end of the inclined connecting rod 63 has a second connecting end 64, which is set on the rotating ring 65. The center of the top end of the planetary gear 6 is fixed to the installation of the steering ball head 62 by the ball socket of the first connecting end 61. The steering ball head 62 is fixedly connected to the inclined connecting rod 63. The top of the inclined connecting rod 63 is fixedly connected to the rotating ring 65 by the second connecting end 64. The planetary gear 6 rotates in the same direction on the limiting gear ring 5 due to the rotational meshing effect of the sun gear 4. The inclined connecting rod 63 changes the specific connection angle with the planetary gear 6 through the steering ball head 62, so that the inclined connecting rod 63 can follow the planetary gear 6 to rotate outside the sun gear 4, ensuring the stability of the planetary gear 6 during installation and use.

[0031] The ball socket limits the connection between the first connecting end 61 and the steering ball head 62. That is, the steering ball head 62 will change its connection angle with the ball socket due to the steering force, but the steering ball head 62 will always be in the ball socket and will not be separated from the ball socket due to the force. This ensures that the first connecting end 61, the second connecting end 64 and the rotating collar 65 always remain connected to achieve the connection of the planetary gear 6.

[0032] The top of the rotating column 3 is provided with an annular groove, and the rotating collar 65 is movably connected to the annular groove. That is, the rotating collar 65 is fitted on the annular groove and movably connected to the annular groove. The rotating collar 65 follows the planetary gear 6 and rotates at the same frequency on the annular groove to ensure that the planetary gear 6 is limited during the rotation of the sun gear 4, and to prevent it from being dislodged from the sun gear 4 and the limiting gear ring 5 due to the gravity of the second mixing device 8 and the material changing resistance.

[0033] The second mixing device 8 includes a second rotating rod 81. A connecting frame 84 is provided at the bottom of the second rotating rod 81. The connecting frame 84 is set in the mounting base 83. A plurality of stirring columns 82 are evenly arranged along the edge of the mounting base 83. The second rotating rod 81 of the second mixing device 8 is fixedly connected to the bottom panel of the planetary gear 6. Multiple sets of stirring columns 82 are evenly distributed on the outside of the second rotating rod 81, and the top of all stirring columns 82 is fixedly connected to the bottom panel of the planetary gear 6. Multiple sets of stirring columns 82 cooperate with the second rotating rod 81 to mix the slurry in the upper cavity of the preparation tank. Its speed is lower than the rotation speed of the first rotating rod 71, and it performs mixing treatment on the slurry in the non-settling state.

[0034] See Figure 3The first mixing device 7 includes a first rotating rod 71, a main mounting base 72 at the lower end of the first rotating rod 71, a propeller 73 on the main mounting base 72, a scraper seat 74 below the main mounting base 72, a first scraper frame 75 and a second scraper frame 76 on the scraper seat 74. The first mixing device 7 establishes a fixed connection with the sun gear 4 through the first rotating rod 71, that is, the first rotating rod 71 rotates in the same frequency as the sun gear 4, driving the main mounting base 72 and the scraper seat 74 to rotate in the same frequency.

[0035] Multiple sets of propellers 73 are evenly arranged on the main mounting base 72. All propellers 73 are designed with a streamlined structure that extends in opposite directions, which can guide and mix the slurry in contact with them. They can all adapt well to the slurry stirring resistance and complete the mixing process.

[0036] The scraper seat 74 fixes the connection between the first scraper frame 75 and the second scraper frame 76 on both sides. The first scraper frame 75 and the second scraper frame 76 rotate in the same frequency as the first rotating rod 71 to perform mixing and scraping treatment on the lower wall plate of the preparation tank. The rotation of multiple sets of stirring, mixing and scraping devices can generate a certain degree of high-frequency vibration, which can have a certain vibration effect on the structure of the preparation tank. This can effectively prevent the slurry from settling and solidifying on the lower wall plate of the preparation tank, and ensure the homogeneity of the slurry preparation.

[0037] See Figure 4 The first scraper frame 75 has a side scraper 751 on its edge. The inner side of the first scraper frame 75 is connected to the scraper seat 74 by an anti-detachment frame 753. A bottom scraper 752 is provided between the first scraper frame 75 and the scraper seat 74. The first scraper frame 75 is an arc-shaped frame with an extended structure. The side scraper 751 on its edge serves as a structure for scraping the side wall of the preparation tank. While the side scraper 751 scrapes the side wall of the preparation tank as the first scraper frame 75 moves, the bottom scraper 752 also scrapes the bottom wall of the preparation tank. This can remove all the sediment in the possible sedimentation areas of the preparation tank, ensuring that the slurry is mixed evenly and discharged stably.

[0038] The second scraper 76 has the same structural design as the first scraper 75. The second scraper 76 and the first scraper 75 are arranged symmetrically about the scraper seat 74. The second scraper 76 and the first scraper 75 are respectively located on both sides of the scraper seat 74. When the first rotating rod 71 rotates, it drives the first scraper 75 and the second scraper 76 to rotate at the same frequency, and repeatedly scrapes the side wall of the preparation tank.

[0039] The bottom of the mixing tank is equipped with a discharge pipe and a discharge valve to control the discharge of the mixed slurry.

[0040] The bottom edge of the mixing tank is equipped with a waste discharge port and a movable material removal cover. After the mixing tank has been used for a long time, if there is any sediment that has been scraped off and has not been mixed with the slurry again, the movable material removal cover can be opened to remove the sediment scraped off by the two sets of scrapers, ensuring that the mixing tank can be put into use again.

[0041] This utility model provides an anti-deposition structure for a PBT slurry preparation tank. The tank has a liftable cover and a rotation control assembly. A rotating motor drives a sun gear 4 to rotate, which in turn drives a planetary gear 6 to rotate synchronously within a limiting gear ring 5. This controls the rotation of a first mixing device 7 and a second mixing device 8 within the tank, mixing the PBT slurry. During the rotation of the first mixing device 7, the high-speed rotation of the propeller 73, the first scraper 75, and the second scraper 76 mixes the slurry in the lower section of the tank cavity. During the operation of the second mixing device 8 in sync with the planetary gear 6, the second rotating rod 81 and multiple sets of stirring columns 82 mix the slurry in the middle section of the tank cavity. Adjusting the rotation speed of the stirring devices during PBT slurry mixing effectively prevents material deposition.

[0042] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
