Description

Technical Field

[0001] The utility model relates to the technical field of zinc oxide production, in particular to a batching device for zinc oxide processing. Background Art

[0002] Zinc oxide is an oxide of zinc, which is insoluble in water but soluble in acid and strong alkali. Zinc oxide is a commonly used chemical additive and is widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints and coatings, batteries, flame retardants and other products. At present, it is inconvenient to adjust the discharge port of zinc oxide during production, resulting in users being able to only batch at the same place during use, affecting the batching rate.

[0003] A Chinese patent discloses an automatic batching device for zinc oxide production (authorization announcement number CN215540208U). The patented technology is provided with pressure sensors at both ends of the bottom of the storage tank and between the batching box, so that when the ingredients are put into the storage tank, as the ingredients continue to increase, the weight of the storage tank continues to increase. When the ingredients inside reach the preset value of the pressure sensor, the pressure sensor sends a signal to the controller, and the controller controls the solenoid valve to open, thereby automatically introducing the raw materials inside the storage tank into the batching chamber, avoiding the need for staff to manually weigh the ingredients. However, it is impossible to pre-mix the ingredients, so that stirring and mixing can only be started after all the ingredients are put into the mixing drum, thereby reducing the production efficiency of zinc oxide.

[0021] Working principle: When the utility model is in use, first, start the drive motor 11 to work through an external power supply. The drive motor 11 drives the transmission shaft 12 to rotate. The rotation of the transmission shaft 12 drives the worm 36 to rotate through the meshing of the driving bevel gear 38 and the driven bevel gear 37. The rotation of the worm 36 drives the worm wheel 35 to rotate. The rotation of the worm wheel 35 drives the stirring shaft 33 to rotate. The rotation of the stirring shaft 33 drives a plurality of stirring paddles 34 to rotate. Thus, when the staff inputs the zinc oxide production ingredients into the inner cavity of the feeding box 24 from the feeding port 25, the ingredients can be pre-stirred by the rotation of the plurality of stirring paddles 34. The weight of the feeding box 24 can be detected through the setting of the pressure sensor 22. Thus, when the input ingredient amount reaches the set value, the drive motor 11 can drive the mixing drum 5 to reset. When the push toggle plate 31 moves leftward overcoming the resistance of the return spring 32, the discharge pipe 26 can be dropped vertically downward and inserted into the inner cavity of the communicating pipe 6. By opening the third solenoid valve 28 and the second solenoid valve 7, the pre-stirred ingredients in the inner cavity of the feeding box 24 can be input into the inner cavity of the mixing drum 5 through the discharge pipe 26 and the communicating pipe 6. After the ingredient conduction is completed, push the convex plate 29 again to drive the discharge pipe 26 to move upward and reset. Thus, when the toggle plate 31 is released, the baffle 30 can be reset to the right under the action of the return force of the return spring 32 to limit the discharge pipe 26. When the drive motor 11 is restarted to drive the transmission shaft 12 to rotate, the mixing drum 5 can be driven to rotate synchronously. At the same time, start the drive motor 13 through an external power supply to drive the square rod 20. The rotation of the square rod 20 drives the square hole round pipe 14 to rotate. The rotation of the square hole round pipe 14 drives a plurality of stirring blades 15 to rotate. By the reverse rotation of the stirring blades 15 compared with the mixing drum 5, the centrifugal force can be avoided from reducing the mixing efficiency of the ingredients. In addition, by starting two electro-hydraulic push rods 17 to drive the movable plate 18 to move left and right reciprocally, the square hole round pipe 14 can be slid left and right on the outer wall of the square rod 20, and a plurality of stirring blades 15 can be driven to deeply stir the ingredients in different areas of the inner cavity of the mixing drum 5 to improve the mixing uniformity. When the ingredient mixing is completed, the first solenoid valve 9 can be opened, and the proportioned ingredients can be discharged from the discharge pipe 8.
