Description

Technical Field

[0001] The present invention relates to the technical field of chemical co-precipitation, and particularly to a co-precipitation preparation device for nano-level yttrium-stabilized zirconia powder. Background Art

[0002] Among the preparation methods of zirconia, the co-precipitation method is a commonly used and effective method. In this method, zirconium salts and other ions (usually metal salts) are co-precipitated in a solution to form a composite precipitate. After the reaction, the precipitate needs to be separated by filtration or centrifugation; then the precipitate is washed multiple times to remove residual impurities in the solution; and then through appropriate post-treatment (such as calcination), zirconia is obtained. The co-precipitation method has the advantages of simple operation, low cost, and the ability to obtain high-purity materials, and is widely used in the preparation of zirconia and its composites.

[0003] After retrieval, in the prior art during co-precipitation, by controlling the speed, temperature, and stirring rate of adding the precipitant, the particle size and uniformity of the precipitate can be controlled; however, in order to stir evenly, it is inevitable to set up a complicated stirring device inside the device, which is not only not conducive to subsequent filtration, but also after long-term use, the surface of the stirring impeller or the stirring frame adheres more, making it inconvenient to clean, and it must be cleaned when changing batches, which greatly increases the cost. Therefore, we propose a new co-precipitation device without a stirring mechanism to improve production efficiency. Summary of the Invention

[0004] Aiming at the technical problem that the built-in stirring mechanism in the prior art is prone to cause difficulties in rapid cleaning in the later stage, the present invention adopts the following technical solutions:

After the bone-shaped core rod continues to move, both the rubber balloon and the water inlet pipe release water, increasing the water output and improving the flushing effect.

With the setting of the energy storage pump 18, the coprecipitant with different flow rates can be pumped out intermittently, changing the wave crest of the vortex and playing a mixing role.

[0031] Refer to Figure 7 , the two piston plates are respectively in a basin-shaped structure with opposite opening directions, and two piston rings are sleeved on the circumferential outer wall of each piston plate; it is ensured that the piston plate does not skew during the propulsion, and it is ensured that its plate surface is always perpendicular to the axis line of the pump housing.

On both sides of one end of the cantilever beam 7 close to the winding motor 8, symmetric L-shaped support plates 10 are respectively fixed, and fixed pulleys are fixed at the ends of the L-shaped support plates 10 away from the cantilever beam 7; the fixed pulleys are located above the corresponding anti-slip-off chutes 2001; the two pulling ropes 11 bypass the corresponding fixed pulleys and are fixed at the top edge of the potato chip-shaped screen 15 below; by controlling the counterclockwise rotation of the winding motor 8, the two pulling ropes 11 can be wound simultaneously to slowly lift the potato chip-shaped screen 15 containing the precipitate.

[0035] Referring to Figure 1 、 Figure 3-4 and Figure 8 ,on the side of the top end of the outer barrel 20 away from the support frame 1, i.e., the front end, there is a discharge notch 2002. An arc-shaped support plate 16 with an upward-opening tile-shaped structure is fixed at the lower opening of the outer circumference of the outer barrel 20 near the discharge notch 2002; on one side of the outer barrel 20 near the top end and away from the discharge notch 2002, there is a push plate insertion hole 2003, and a discharge push plate 2 is slidably inserted into the push plate insertion hole 2003.

The radian of the lower surface of the discharge push plate 2 is adapted to the radian of the potato chip-shaped screen 15 and the arc-shaped support plate 16. By setting the discharge push plate 2 and the electric push rod 3, when separating the filtered sediment, only need to control the extension rod of the electric push rod 3 to extend, and at this time, the discharge push plate 2 attached to the surface of the potato chip-shaped screen 15 can slowly scrape the sediment on the surface.

[0036] Referring to Figure 1 、 Figure 4-6 ,a U-shaped bracket 101 is fixed above the barrel opening of the outer barrel 20 on the front side of the support frame 1, and a flushing mechanism is arranged above the U-shaped bracket 101. The flushing mechanism includes a reversing energy storage valve 5 horizontally fixed on the U-shaped bracket 101. The reversing energy storage valve 5 includes a cylindrical barrel-shaped valve body, and a water inlet pipe 6 is inserted into the outer circumference of the valve body near the middle. Symmetrically arranged water delivery pipes 12 are inserted into the outer circumference of the valve body near both ends respectively; on the outer circumference of the outer barrel 20 near the top end, symmetrically distributed side guard plates 21 are respectively fixed, and symmetrically arranged L-shaped clamping plates 14 are respectively fixed at the top ends of the two side guard plates 21. Adjustable spray heads 13 with symmetrically arranged pipe orifices facing the bottom of the groove of the potato chip-shaped screen 15 are respectively clamped in the two L-shaped clamping plates 14; the water inlet end of the adjustable spray head 13 is communicated with the water delivery pipe 12 on the corresponding side; three coaxially arranged water storage chambers 503 are opened on the inner circumference of the valve body; and a bone-shaped core rod 501 is slidably connected in the valve body. The diameter of the middle rod of the bone-shaped core rod 501 is smaller than the inner diameter of the valve body; an extension frame is fixed on one side of the support frame 1 near the opening of the valve body, and a second reduction motor 25 is fixed on the extension frame. The top end of the output shaft of the second reduction motor 25 is fixed with a runner 22. A connecting rod 2201 is rotatably connected near the outer circumference of the surface of the runner 22, and the other end of the connecting rod 2201 is hinged to the end of the bone-shaped core rod 501; by setting like this, through the alternating propulsion of the runner 22 and the connecting rod 2201, the water from the middle can be alternately discharged from the two side water delivery pipes 12, and then wash down from different sides of the potato chip-shaped screen 15 to wash the sediment above it.

After the bone-shaped core rod 501 continues to move, both the rubber balloon 504 and the water inlet pipe 6 release water, increasing the water output and improving the flushing effect.

[0038] Refer to Figure 1 and Figure 5 , a protective barrel 4 is embedded near the end of the energy storage pipe 502 in the middle of the support frame 1. By providing the protective barrel 4, it can ensure that the expanded rubber balloon 504 can return to its original state when the water pressure decreases, increasing its service life.

[0039] When the device is in use, first control the winding motor 8 to reverse to ensure that the potato chip-shaped screen 15 is lowered to fit the surface of the concave bottom plate 26 at the bottom. Then close the solenoid valve 23, and raw materials can be added and waiting for the reaction. During the reaction, first turn on the reduction motor 186 in the energy storage pump 18, and then pass the coprecipitant into it through the coprecipitant supply pipe 17. Finally, it is obliquely injected into the outer barrel 20 through the non-centripetal insertion pipe 24 obliquely inserted into the outer barrel 20. That is, when adding the coprecipitant, a vortex is formed inside, which then drives the substances inside to move, facilitating the acceleration of the mixing reaction and the formation of precipitates. With the setting of the energy storage pump 18, it can intermittently pump out coprecipitants with different flow rates, changing the wave crest of the vortex and playing a mixing role; after the reaction ends, lift the substances deposited on the potato chip-shaped screen 15 together with the potato chip-shaped screen 15 until the bottom of its groove is flush with the bottom of the arc-shaped support plate 16. Then control the extension rod of the electric push rod 3 to extend, and at this time, the discharge push plate 2 that fits the surface of the potato chip-shaped screen 15 can slowly scrape the precipitates on the surface.
