Description

Technical Field

[0001] The invention belongs to the technical field of rice husk ash utilization, in particular to a device for purifying high-quality silicon dioxide from rice husk ash. Background Art

[0002] Rice husk ash is an industrial waste residue produced by the combustion or gasification process of biomass power plants using rice husks as fuel. Rice husk ash is mainly composed of silicon dioxide and unburned carbon, of which the content of silicon dioxide is generally more than 80%. Rice husk ash has many important functions and uses, including water purification, soil improvement, corrosion prevention and building materials.

[0003] Silica extracted from rice husk ash can be further purified to obtain high-quality products; purification methods include combustion, alkali extraction, and other commonly used high-purity silica preparation methods such as quartz heat treatment, chemical vapor deposition, sol-gel, and wet chemical methods;

[0004] However, during the purification process, acid needs to be added to decompose the sodium ions and silica, and the silica is precipitated. The silica is then extracted. However, in this step, when the whole is directly poured out or sucked out, the silica at the bottom will be driven upward and re-contacted with the sodium ions, affecting the purification effect.

[0005] In view of this, a device for purifying high-quality silicon dioxide from rice husk ash is proposed. Summary of the invention

[0006] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

[0007] In view of the following technical problems in the prior art: acid needs to be added during the purification process to decompose sodium ions and silica, precipitate silica, and then extract the silica. However, in this step, when the whole is directly poured out or sucked up, the silica at the bottom will be driven upward and re-contact with the sodium ions, affecting its purification effect.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions: a device for purifying high-quality silica from rice husk ash, comprising a recovery cylinder, a rotating rod and a motor; the rotating rod passes through the recovery cylinder, and the bottom end of the rotating rod is rotatably connected to the inner edge of the bottom end of the recovery cylinder, the motor is installed on the top surface of the recovery cylinder, and a feeding port is provided at the top of the recovery cylinder, wherein the feeding port is used to add raw materials to the inside of the recovery cylinder, and an extraction tube is docked at the side of the recovery cylinder; a baffle is hinged on the outer side of the rotating rod, a rotating groove is provided on the surface of the baffle, and a rotating shaft is rotatably connected to the inner edge of the rotating groove, and the rotating shaft passes through the rotating rod, and through the setting of the rotating shaft, the baffle can rotate around the rotating shaft as the center of a circle.

[0009] As an optimal technical solution for purifying high-quality silica from rice husk ash, a storage groove is opened on the inner edge of the rotating groove, and a blocking pad is arranged in the storage groove, wherein the blocking pad is made of a flexible material. When the rotating rod rotates, the blocking pad can be squeezed into the storage groove. Since the blocking pad is flexible, the blocking pad can be restored when not squeezed by the rotating rod.

[0010] As an optimal technical solution for purifying high-quality silicon dioxide from rice husk ash, a plurality of stirring rods are arranged on the outside of the rotating rod, and the plurality of stirring rods are staggered. When the rotating rod rotates, the stirring rods can be linked to fully stir the rice husk powder, sodium hydroxide and deionized water in the recovery cylinder.

[0012] As an optimal technical solution for purifying high-quality silica from rice husk ash, a guide channel is opened on the upper inner edge of the rotating rod near the linkage cavity, and a displacement rod is telescopically moved in the guide channel.

[0014] As an optimal technical solution for purifying high-quality silica from rice husk ash, a gear three is installed at the output end of the motor, and the gear three is meshed with the gear two for transmission. When the motor is running, the rotating rod can rotate by relying on the meshing transmission relationship between the gear three and the gear two.

[0015] The beneficial effects of the present invention are as follows: after the silicon dioxide is precipitated, the spiral pattern is rotated, and under the action of the threaded transmission, the displacement rod can rotate and extend, and under the action of the hinge connection between the displacement rod and the U-frame, the U-frame can extend and retract, and under the action of the meshing transmission, the gear 1 rotates and the baffle flips, so that the recovery cylinder is roughly divided into two layers, and the blocking effect can be further improved by the blocking pad, and the liquid in the extraction tube is absorbed through the extraction tube.

[0030] Example 1

[0031] Reference Figure 1 , 2, 3 and 6 are the first embodiment of the present invention, which provides a device for purifying high-quality silica from rice husk ash, comprising a recovery cylinder 100, a rotating rod 200 and a motor 400; the rotating rod 200 runs through the recovery cylinder 100, and the bottom end of the rotating rod 200 is rotatably connected to the inner edge of the bottom end of the recovery cylinder 100, the motor 400 is installed on the top surface of the recovery cylinder 100, a feeding port 101 is provided at the top of the recovery cylinder 100, wherein the feeding port 101 is used to add raw materials to the inside of the recovery cylinder 100, and an extraction pipe 102 is docked on the side of the recovery cylinder 100; a baffle 300 is hinged on the outer side of the rotating rod 200, a rotating groove 301 is provided on the surface of the baffle 300, and a rotating shaft 203 is rotatably connected to the inner edge of the rotating groove 301, the rotating shaft 203 runs through the rotating rod 200, and the baffle 300 can rotate around the rotating shaft 203 as the center of a circle through the setting of the rotating shaft 203.

[0032] Specifically, a plurality of stirring rods 201 are arranged on the outer side of the rotating rod 200, and the plurality of stirring rods 201 are staggered. When the rotating rod 200 rotates, the stirring rod 201 can be linked to fully stir the rice husk powder, sodium hydroxide and deionized water in the recovery drum 100; a linkage cavity 202 is provided in the middle of the rotating rod 200, and one end of the rotating shaft 203 extending into the linkage cavity 202 is connected to a gear 204, and a U-shaped frame 205 is provided in the linkage cavity 202 for telescopic movement, wherein the inner edge of the U-shaped frame 205 is a smooth surface, and a rack 206 is fixedly installed at the open end of the U-shaped frame 205, wherein the teeth of the rack 206 face the U-shaped frame 205, and the rack 206 is meshed with the gear 204 for transmission. When the U-shaped frame 205 is extended or retracted, the rack 206 can control the gear 204 to move. 4 rotates in positive and negative directions; a guide channel 208 is provided at the upper inner edge of the rotating rod 200 near the linkage chamber 202, and a displacement rod 207 is telescopically moved in the guide channel 208. The bottom end of the displacement rod 207 is hinged to the top surface of the U-shaped frame 205. When the displacement rod 207 telescopes, it can link the U-shaped frame 205 to telescope; a section of the top end of the displacement rod 207 extending out of the guide channel 208 is provided with a spiral pattern 209, and the outer side of the top end of the rotating rod 200 is connected to a carrier frame 210 and a second gear 212, and a threaded hole 211 is provided in the middle of the second gear 212. The spiral pattern 209 and the threaded hole 211 are threadedly driven. When the top end of the displacement rod 207 is rotated, the displacement rod 207 moves in a rotating and telescopic manner under the action of the threaded transmission.

[0033] Specifically, a gear 3 401 is installed at the output end of the motor 400 , and the gear 3 401 is meshed with the gear 2 212 for transmission. When the motor 400 is running, the rotating rod 200 can rotate by virtue of the meshing transmission relationship between the gear 3 401 and the gear 2 212 .

[0034] Example 2

[0035] Reference Figure 2 , 4 , 5 and 6 are the second embodiment of the present invention, which is different from the previous embodiment in that a receiving groove 302 is provided at the inner edge of the rotating groove 301, and a blocking pad 303 is provided in the receiving groove 302, wherein the blocking pad 303 is made of a flexible material, and when the rotating rod 200 rotates, the blocking pad 303 can be squeezed into the receiving groove 302. Since the blocking pad 303 is flexible, the blocking pad 303 can be restored when it is not squeezed by the rotating rod 200.

[0036] This can be achieved through two implementations: adding the ground and impurity-removed rice husk powder to the recovery drum 100 through the feed port 101, adding an appropriate amount of sodium hydroxide and deionized water to the feed port 101, and heating the recovery drum 100 through an external heating component, and then the motor 400 drives the gear three 401, and the gear three 401 is meshed with the gear two 212, so that the rotating rod 200 and the stirring rod 201 rotate to stir the inside of the recovery drum 100, so that it is kept in a weakly alkaline environment, and reacts for a period of time, so that the silicon dioxide in the rice husk powder reacts with the sodium hydroxide to generate sodium silicate, and then acid is added to the feed port 101 to acidify it. The unstable characteristics of sodium silicate will cause it to decompose into silicon dioxide and sodium ions, and the silicon dioxide will precipitate, while the sodium ions are in the liquid, and the motor 400 stops. Operation, at this time, the spiral pattern 209 is rotated, and under the action of the thread transmission, the displacement rod 207 can rotate and extend, and under the action of the hinge between the displacement rod 207 and the U-frame 205, the U-frame 205 can extend and retract, and under the action of the meshing transmission, the gear 1 204 is rotated, and the baffle 300 is flipped, so that the recovery cylinder 100 is roughly divided into two layers, and the blocking effect can be further improved by the blocking pad 303, and the liquid in the extraction tube 102 is absorbed through the extraction tube 102. At this time, the silicon dioxide at the bottom layer is not easily affected by the extraction tube 102. At this time, the liquid and a large amount of sodium ions are sucked away, thereby improving the purification quality of silicon dioxide. When the baffle 300 is rotated and stored, it will not affect the precipitation of silicon dioxide and the production reaction of sodium silicate.

[0037] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
