[0002] Nano zinc oxide is an important functional material widely used in rubber, coatings, pharmaceuticals and other fields. In its production process, precipitation method (such as direct precipitation method and uniform precipitation method) is the mainstream process. The final product needs to be washed with water multiple times to remove residual impurity ions to meet the purity requirements. The water washing work is mainly carried out by adding deionized water into the reaction vessel, stirring and letting it stand to separate into layers, and then draining the supernatant. This process is repeated many times. Traditional equipment requires a long standing time for solid-liquid separation, resulting in low work efficiency. Utility Model Content

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4This utility model provides a nano zinc oxide water washing device, including a reaction vessel 1 and four support legs 2. The lower end of the reaction vessel 1 is uniformly fixed with four support legs 2. The upper end of the reaction vessel 1 is connected to a top cover 3 through a flange. A motor 4 is fixedly mounted on the upper end of the top cover 3. The lower end of the motor shaft of the motor 4 passes through the top cover 3 and is fixedly connected to a hollow rotating shaft 5. A water washing structure 6 is fixedly mounted on the bottom surface of the inner cavity of the reaction vessel 1. The upper end of the water washing structure 6 is inserted into the hollow rotating shaft 5. A water baffle 7 is sleeved on the outer wall of the water washing structure 6, and the outer wall of the water baffle 7 is fixedly connected to the inner wall of the reaction vessel 1. A water suction pipe 8 is passed through and connected to the inner wall of the water baffle 7. The outer end of the water suction pipe 8 passes through the reaction vessel 1 and is fixedly connected to one end of a negative pressure pump 9. The other end of the negative pressure pump 9 is fixedly connected to a drain pipe 10.

[0015] The reactor 1 provides space for washing the nano-zinc oxide raw material. The top cover 3 ensures airtightness, guaranteeing the washing effect and preventing impurities from entering. The support legs 2 ensure the overall stability of the equipment. The motor 4 drives the hollow shaft 5, which in turn drives the stirring components inside the washing structure 6 to rotate, fully agitating the raw material during the washing process. After one washing cycle is completed, the position holding the raw material can be raised to remove it from the washing liquid. The water baffle 7 protects the components in the washing structure 6. The washing liquid after one washing cycle is extracted by the negative pressure pump 9 and the water suction pipe 8 and discharged to a suitable location through the drain pipe 10. It can quickly separate solids and liquids without long-term settling and stratification, and can proceed to the next washing cycle. It is convenient to use and highly practical.

[0016] The water washing structure 6 includes a hydraulic cylinder 67. The lower end of the hydraulic cylinder 67 is fixedly mounted on the bottom surface of the inner cavity of the reactor 1. The upper end of the piston rod of the hydraulic cylinder 67 is fixedly mounted on a base 64. The outer wall of the base 64 is connected to an outer frame 66 through a microporous ceramic membrane 65. A water baffle 7 is sleeved on the outer wall of the piston rod of the hydraulic cylinder 67. A rotating rod 61 is rotatably mounted on the surface of the base 64. Two retaining strips 62 are symmetrically fixed to the outer wall of the rotating rod 61. The rotating rod 61 and the two retaining strips 62 are all inserted into the inner wall of the hollow rotating shaft 5. The hollow rotating shaft 5 is clearance-fitted with the rotating rod 61 and the two retaining strips 62. Two stirring blades 63 are symmetrically fixed to the lower end of the outer wall of the rotating rod 61.

[0017] During the washing process, motor 4 is turned on. Motor 4 drives the rotating rod 61 to rotate synchronously through the clamping strip 62, and drives the two stirring blades 63 at the lower end to rotate. Low-speed stirring and shearing avoid secondary agglomeration caused by high-speed stirring. After the first washing is completed, hydraulic cylinder 67 is turned on to control the piston rod to move upward and drive the base 64 to move upward. At this time, the base 64 drives the microporous ceramic membrane and the outer frame 66 to move upward at the same time, and drives the raw materials inside to move upward and get away from the washing liquid. At this time, the rotating rod 61 and the clamping strip 62 also enter the hollow rotating shaft 5 without obstruction. After washing, the material is filtered through the microporous ceramic membrane 65 and solid-liquid separation is achieved with the help of negative pressure suction (the membrane pore size is 0.1-0.5μm, which can retain nanoparticles but allows water molecules and small ions to pass through). Negative pressure suction reduces the filtration resistance and avoids the high pressure damage of traditional pressure filtration. It can efficiently complete solid-liquid separation and improve the efficiency of the washing process.

[0018] The outer wall of the hydraulic cylinder 67 is fitted with a protective sleeve 11, and the lower end of the protective sleeve 11 is fixedly connected to the bottom surface of the inner cavity of the reactor 1.

[0019] The protective sleeve 11 serves to protect the hydraulic cylinder 67.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
