Description

Technical Field

[0001] The utility model relates to the technical field of zinc oxide production, in particular to a zinc oxide powder precipitation and impurity removal device. Background Art

[0002] Zinc oxide is an oxide of zinc that is insoluble in water but soluble in acids and strong bases. Zinc oxide is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints and coatings, ointments, adhesives, flame retardants and other products. During the production of zinc oxide, it needs to be treated by a precipitation and impurity removal device. The main process is to filter and remove impurities by dissolving zinc oxide powder in a certain solution while impurities are insoluble in the solution, so as to improve the purity of the zinc oxide powder. However, during the use of the current zinc oxide precipitation and impurity removal device, the zinc oxide powder is generally directly mixed with the reaction solution, and then stirred and mixed by a stirring paddle. This method makes it impossible for the zinc oxide powder to be quickly and fully mixed with the solution, affecting its impurity removal efficiency. Therefore, we propose a zinc oxide powder precipitation and impurity removal device to solve the above problem. Utility Model Content

When using this precipitation and impurity removal device, open the sealing cover of the liquid inlet pipe 15, and then The reaction solution can be first sent to the interior of the tank body 2 through the liquid inlet pipe 15, and the motor is started to drive one of the stirring paddles 3 to rotate. With the cooperation of the two gears 4, the two stirring paddles 3 can be rotated synchronously in opposite directions. Then, after the zinc oxide powder is poured into the interior of the box body 5, the reciprocating mechanism 7 is driven to vibrate the mesh plate 6. After the mesh plate 6 vibrates, the zinc oxide powder can be evenly dropped into the interior of the tank body 2, and the dropped powder will be fully mixed with the rotating reaction solution, thereby improving the mixing efficiency of the two. After the mixing is completed, the solenoid valve 10 on the discharge pipe 9 is opened, and then the mixed solution will be filtered through the filter component 11 and discharged, and the impurities in the solution will be precipitated inside the filter component 11.

The surfaces of the rotating rods 702 are fixed with transmission wheels 706, and the two transmission wheels 706 are connected by belts 707, so that the two rotating rods 702 can be driven to rotate at the same time under the action of one motor, thereby saving production costs. A cam 703 is fixed at one end of the rotating rod 702, and the top of the box body 5 slides through two T-shaped rods 704. The T-shaped rods The top of 704 is respectively fitted with the corresponding surface of cam 703, and a spring 705 is fixed on the T-shaped rod 704.
