Description

Technical Field

[0001] This utility model relates to the field of silica sol technology, specifically an intermediate storage tank for preparing silica sol. Background Technology

[0002] Silica sol is a colloidal solution that is odorless and non-toxic. Silica sol is a dispersion of nano-sized silica particles in water or a solvent; while the intermediates of silica sol are intermediate products in the production of silica sol. Silica sol polishing slurry is mainly used for polishing large-scale integrated circuits, sapphire substrates for light-emitting diodes (LEDs), and sapphire cover plates for mobile phones, watches, etc.

[0003] Currently, during the storage of silica sol intermediates in storage tanks, large-particle silica sol intermediates tend to settle due to gravity, resulting in uneven particle size distribution of silica sol intermediates throughout the storage tank. This affects the storage effect and quality of the silica sol intermediates. Utility Model Content

A guide groove is provided at the corresponding position of the lifting plate relative to the support guide rod, and the lifting plate is slidably sleeved on the outside of the support guide rod through the guide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application sets up a sleeve roller and a stirring mechanism. By using the rotation of the sleeve roller to stir the material, the mixing effect of large and small particles in the material is increased, so as to avoid the problem of stratification during the material storage process. Therefore, it effectively improves the storage effect of the silica sol intermediate.

[0015] 2. This application improves the mixing effect of the stirring mechanism by setting a self-rotating stirring mechanism that can rotate around the axis of the roller while also rotating on its own axis. This prevents the stirred material from forming a regular vortex state, thereby further improving the mixing efficiency and storage effect of the silica sol intermediate.

[0023] 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.

[0024] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution for an intermediate storage tank for preparing silica sol, including a tank body 1, a fixed rod 2 fixedly connected inside the tank body 1, a sleeve roller 3 sleeved on the outside of the fixed rod 2, and two sets of stirring mechanisms 4 arranged on the outside of the sleeve roller 3. The two sets of stirring mechanisms 4 are arranged in a linear array above and below. The stirring mechanism 4 includes a first bevel gear 401 and three stirring blades 402 rotating on the outside of the sleeve roller 3. The ends of the stirring blades 402 are fixedly connected to a second bevel gear 403 that meshes with the first bevel gear 401. The first bevel gear 401 and the second bevel gear 403 are arranged perpendicular to each other. The first bevel gear 401 and the second bevel gear 403 are both rotatably connected inside the sleeve roller 3, and the first bevel gear 401 is slidably sleeved on the outside of the fixed rod 2. A rotating mechanism for driving the sleeve roller 3 to rotate is provided on the tank body 1, and the bottom end of the fixed rod 2 is fixedly connected to the bottom wall inside the tank body 1.

[0025] By rotating the sleeve roller 3, the sleeve roller 3 drives the stirring mechanism 4 to revolve around the axis of the fixed rod 2, thereby using the stirring mechanism 4 to stir the material. While the stirring mechanism 4 revolves, the sleeve roller 3, through the cooperation of the second bevel gear 403 and the first bevel gear 401, causes the stirring blade 402 in the stirring mechanism 4 to rotate, thus increasing the stirring effect of the stirring mechanism 4.

[0026] like Figure 1 - Figure 4 As shown, the rotating mechanism includes a servo motor 5 and a turntable 6. The turntable 6 is slidably sleeved on the outside of the sleeve roller 3, and the turntable 6 rotates in a sealed cavity in the rotating hole at the top of the tank body 1. The servo motor 5 is installed on the upper part of the tank body 1, and pulleys are fixedly sleeved on the outside of both the servo motor 5 and the turntable 6. A conveyor belt 7 is connected between the two pulleys. A lifting mechanism that drives the sleeve roller 3 to rise and fall is provided on the tank body 1. The servo motor 5 is electrically connected to the power supply.

[0027] The servo motor 5 drives the turntable 6 to rotate via the conveyor belt 7, and the turntable 6 in turn drives the roller 3 to rotate.

[0028] like Figure 1 - Figure 3 As shown, the lifting mechanism includes a lifting plate 8 and a hydraulic cylinder 9. The hydraulic cylinder 9 is installed on the upper part of the tank body 1, and the output end of the hydraulic cylinder 9 is fixedly connected to the bottom of the lifting plate 8. The lifting plate 8 is rotatably sleeved on the top of the sleeve roller 3.

[0029] The hydraulic cylinder 9 drives the lifting plate 8 to rise and fall, and the lifting plate 8 will move axially along the support guide rod 11. The lifting plate 8 drives the sleeve roller 3 to rise and fall, and the sleeve roller 3 can rotate at the bottom of the lifting plate 8.

[0030] like Figure 1 - Figure 3As shown, a crossbeam 10 is fixedly connected to the top of the fixed rod 2. The crossbeam 10 is located above the tank body 1, and a support guide rod 11 is fixedly connected between the crossbeam 10 and the tank body 1. A guide groove is provided at the corresponding position of the lifting plate 8 relative to the support guide rod 11, and the lifting plate 8 is slidably sleeved on the outside of the support guide rod 11 through the guide groove.

[0031] The crossbeam 10 and the support guide rod 11 are used to increase the stability of the installation of the fixed rod 2.

[0032] like Figure 4 and Figure 5 As shown, a first groove 12 with a circumferential array is provided on the outer side of the sleeve roller 3, and a first rod 13 is slidably arranged in the first groove 12. The first rod 13 is fixedly connected to the inner wall of the turntable 6.

[0033] The cooperation between the first groove 12 and the first rod 13 ensures that the sleeve roller 3 can only slide within the turntable 6 and cannot rotate on its own.

[0034] like Figure 1 - Figure 3 As shown, a feed pipe 14 is fixedly connected to one side of the tank body 1, and a first cover plate 15 is provided at the end of the feed pipe 14. A discharge pipe 16 is fixedly connected to the bottom of the tank body 1, and a solenoid valve is provided on the discharge pipe 16. The discharge pipe 16 is located on one side of the fixed rod 2.

[0035] The material is fed into the tank 1 through the feed pipe 14 for storage and discharged through the discharge pipe 16.

[0036] like Figure 1 - Figure 3 As shown, a maintenance pipe 18 is fixedly connected to the upper part of the tank body 1, and a second cover plate 17 is provided at the end of the maintenance pipe 18.

[0037] like Figure 5 As shown, a second groove 21 is provided on one side of the fixed rod 2, and a second rod 19 is slidably connected in the second groove 21. The second rod 19 is fixedly connected to the inner wall of the first bevel gear 401. A slider 20 is provided on the outside of the fixed rod 2. The slider 20 is rotated in a sealed manner at the bottom end inside the sleeve roller 3. A third rod is fixedly connected to the inner wall of the slider 20. The third rod slides in the cavity of the second groove 21.

[0038] The second groove 21 and the second rod 19 cooperate to make the first bevel gear 401 slide axially along the fixed rod 2, but cannot rotate relative to the fixed rod 2. The first bevel gear 401 includes an inner tube and a bevel plate. The bevel plate is fixedly sleeved on the outside of the inner tube, while the second rod 19 is fixedly connected to the inner wall of the inner tube. The inner tube is slidably sleeved on the outside of the fixed rod 2.
