Specific implementation mode
[0019] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will be described in detail with reference to the accompanying drawings and preferred embodiments regarding the specific implementation mode, structure, features and effects of the present utility model.
[0020] Please refer to Figures 1 - 3 As shown, the present utility model provides a stirring device for producing bio-based polyester polyol compounds, including a tank body 1. The top of the tank body 1 is detachably connected with an upper cover 4, and a discharge port 17 is provided in the middle of the bottom surface of the tank body 1. A rotating shaft 10 driven by a stirring motor is installed in the middle of the bottom surface of the upper cover 4. A stirring assembly for stirring the compound is limited and movable on the outer part of the rotating shaft 10. The stirring assembly includes a plurality of sliding sleeves 13. A connecting rod 14 is arranged between two adjacent sliding sleeves 13. Stirring blades 7 are fixed on the outer surfaces of both sides of the sliding sleeve 13. After the compound material enters the tank body 1, the rotating shaft 10 is driven by the stirring motor to rotate, so that the stirring blades 7 in the stirring assembly stir the compound material. Then, a plurality of sliding sleeves 13 slide vertically along the rotating shaft 10, changing the vertical height of the stirring blades 7, stirring the compound material at different depths in the tank body 1, making the stirring more uniform and sufficient, and improving the purity of the compound.
[0021] Refer to Figures 2 - 3 As shown, protruding slide bars 11 are installed on the outer surfaces of both sides of the rotating shaft 10. Limit stop blocks 12 are arranged at both ends of the protruding slide bars 11. A guide groove 16 for the protruding slide bars 11 to slide through is provided on the inner wall surface of the sliding sleeve 13. The length of the limit stop block 12 is greater than the length of the guide groove 16. The sliding sleeve 13 in the stirring assembly slides vertically along the rotating shaft 10. Due to the arrangement of the guide groove 16 and the protruding slide bars 11, the sliding sleeve 13 makes a directional slide. The maximum sliding distance of the sliding sleeve 13 is blocked by the limit stop block 12, that is, the sliding sleeve 13 does not exceed the vertical height of the limit stop block 12. When the rotating shaft 10 rotates, the sliding sleeve 13 can rotate synchronously, thus ensuring the normal progress of stirring.
[0022] Refer to Figure 2As shown in the figure, on one side of the lower surface of the upper cover 4 close to the rotating shaft 10, there is an electric push rod two 15 for pushing the sliding sleeve 13 to slide up and down. The upper surface of the sliding sleeve 13 is provided with an annular groove, and the pushing end of the electric push rod two 15 is slidably arranged in the annular groove. By pushing the sliding sleeve 13 at the top downward by the electric push rod two 15, through the connection of the connecting rod 14, a plurality of sliding sleeves 13 are driven to move together. When the rotating shaft 10 rotates, the sliding sleeve 13 moves synchronously, and the pushing end of the electric push rod two 15 is limited and slides in the annular groove on the top sliding sleeve 13, ensuring the normal progress of stirring and avoiding movement interference.
[0023] Refer to Figure 1 and Figure 2 As shown in the figure, on both sides of the upper surface of the upper cover 4 located on both sides of the stirring motor, there are respectively a second feed inlet 6 and a first feed inlet 5. The structures of the first feed inlet 5 and the second feed inlet 6 are the same; on the lower surface of the upper cover 4, a feed guide plate 9 is arranged below the second feed inlet 6, and a feed baffle 8 is arranged above the second feed inlet 6 on the lower surface of the upper cover 4. Both the feed baffle 8 and the feed guide plate 9 are inclined. The stirring blade 7 is located below the feed baffle 8 and the feed guide plate 9. Feeding is carried out through the first feed inlet 5 and the second feed inlet 6, that is, feeding from both sides, dispersing the feeding, avoiding over-concentrated feeding. The compound material slides down along the feed guide plate 9 and falls into the tank body 1 through the stirring blade 7. Due to the setting of the feed baffle 8, it is avoided that the material contaminates the surface of the electric push rod two 15 during the feeding process.
[0024] Refer to Figure 1 As shown in the figure, in the middle of the outer surface of the tank body 1, a reinforcing ring seat 2 is installed. On both sides of the upper surface of the reinforcing ring seat 2, electric push rods one 3 are symmetrically installed. The pushing end of each electric push rod one 3 is fixed to the surface of the protruding end of the upper cover 4. By the pushing of the electric push rod one 3, the upper cover 4 is separated from the tank body 1. During the process of the upper cover 4 being lifted upward, the stirring assembly is exposed, facilitating the cleaning of the stirring assembly.
[0025] When the utility model is in use, the rotating shaft 10 is driven to rotate by the stirring motor, and then the stirring blade 7 in the stirring assembly stirs the compound material. Then, several sliding sleeves 13 slide vertically along the rotating shaft 10. The maximum sliding distance of the sliding sleeve 13 is blocked by the limit stop block 12, changing the vertical height of the stirring blade 7. When the rotating shaft 10 rotates, the sliding sleeve 13 moves synchronously, and the pushing end of the electric push rod two 15 is limited and slides in the annular groove on the top sliding sleeve 13, ensuring the normal progress of stirring, stirring the compound material at different depths in the tank body 1, making the stirring more uniform and sufficient, and improving the purity of the compound;
[0026] Feeding is carried out through the first feeding port 5 and the second feeding port 6, that is, feeding from both sides, dispersing the feeding. The compound material slides down along the feeding guide plate 9 and falls into the tank body 1 through the stirring blade 7. Due to the setting of the feeding baffle 8, it is avoided that the material contaminates the surface of the second electric push rod 15 during the feeding process.
