Description

Technical Field

[0001] This utility model relates to the field of silicon micropowder, specifically to a production device for surface modification of silicon micropowder. Background Technology

[0002] Surface modification of silica powder involves introducing specific functional groups or coating a layer of modifier onto the surface of silica powder particles using physical or chemical methods. This alters the surface properties of the silica powder, significantly improving its dispersibility, compatibility, and bonding strength with other materials in organic matrices. It has broad application prospects in numerous fields such as rubber, plastics, and coatings, greatly expanding the application range of silica powder and increasing its added value.

[0003] During the surface modification of silicon micropowder, when the titanate coupling agent reacts with the hydroxyl groups on the surface of silicon micropowder, some alcohol gases are generated. If these gases are directly released into the outside air, they will undergo photochemical reactions with pollutants such as nitrogen oxides in the atmosphere, forming photochemical smog. Therefore, in order to achieve environmentally friendly production, the industry usually adopts collection devices to collect and treat the gases generated by the reaction.

[0004] However, some silicon powder particles will float inside the reactor. When collecting reaction gas, in order to prevent silicon powder from entering the collection pipe along with the gas, a filter plate is usually installed at the end of the pipe. However, silicon powder is very easy to adhere to the filter plate. Over time, it will cause local or even large-area blockage of the filter plate, making it difficult to collect the reactant gas inside the reactor. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a production device for surface modification of silicon micropowder, so as to solve the technical problem that silicon micropowder is very easy to adhere to the filter plate, causing local or even large-area blockage of the filter plate, which makes it difficult to collect the gas inside the reactor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a production device for surface modification of silicon micropowder, comprising a reactor, a motor mounted on the top of the reactor, a rotating rod connected to the end of the motor, a connecting plate fixed to the outer wall of the rotating rod, a protrusion provided at the end of the connecting plate, the protrusion being arc-shaped, a vent hole opened on the inner wall of the reactor, a filter plate mounted on one side of the vent hole, a fixing block fixed inside the reactor, a driving assembly disposed inside the fixing block, a cleaning strip connected to one side of the driving assembly, a pulley mounted at the bottom of the driving assembly, a feed pipe mounted on the top of the reactor, and a discharge pipe disposed at the bottom of the reactor.

[0034] Please see Figure 1 — Figure 5The reactor includes a reactor 1, a motor 3 mounted on top of the reactor 1, a rotating rod 301 connected to the end of the motor 3, a connecting plate 5 fixed to the outer wall of the rotating rod 301, a protrusion 501 with an arc shape at the end of the connecting plate 5, a vent hole 404 on the inner wall of the reactor 1, a filter plate 8 mounted on one side of the vent hole 404, a fixing block 6 fixed inside the reactor 1, a drive assembly inside the fixing block 6, a cleaning strip 7 connected to one side of the drive assembly, a pulley 603 mounted at the bottom of the drive assembly, a feed pipe 102 mounted on the top of the reactor 1, and a discharge pipe 101 mounted on the bottom of the reactor 1. This design solves the problem of silicon micropowder easily adhering to the filter plate. This can cause localized or even large-scale blockage of the filter plate, making it difficult to collect the gas inside the reactor. During the rotation of the connecting plate 5 inside the reactor 1, the arc-shaped protrusion 501 will push the rack 601 connected to one side of the pulley 603 upward. The upward movement of the rack 601 drives the gear 706 to rotate. The gear 706 drives the rotating disk 703 to rotate through the drive column 705. The drive rod 702 drives the cleaning bar 7 to rotate and swing around the limit rod 704.

Then, the gas is conveyed by the blower 402 to the absorption tank 4 through the connecting pipe 401. The absorption plate inside the absorption tank 4 absorbs the pollutants contained in the gas.

[0040] For details regarding the above embodiments, please refer to [link / reference].

[0042] In practical operation: The motor 3 is turned on, driving the rotating rod 301 to rotate. Multiple sets of stirring plates 302 on the outer wall of the rotating rod 301 rotate and stir inside the reactor 1. Then, silicon micropowder and modifier are added sequentially from the feed pipe 102 and liquid inlet pipe 2, respectively. The exhaust fan 402 extracts the gas generated inside the reactor 1 through the vent pipe 403. The gas passes through the filter 8 and enters the vent pipe 403. Then, the gas is conveyed by the exhaust fan 402 through the connecting pipe 401 to the absorption tank 4. The absorption plates inside the absorption tank 4 absorb the pollutants contained in the gas. During the rotation of the rotating rod 301, the connecting plate 5 rotates around the rotating rod 301 inside the reactor 1. When the arc-shaped protrusion 50 at the end of the connecting plate 5... When the fixed block 6 is rotated to the bottom, the upper surface of the protrusion 501 will contact the pulley 603. As the connecting plate 5 rotates, the arc-shaped protrusion 501 will push the rack 601 connected to the pulley upward. The upward movement of the rack 601 will drive the gear 706 to rotate. The gear 706 will drive the rotating disk 703 to rotate through the drive column 705. During the rotation, the drive rod 702 on one side of the rotating disk 703 will slide back and forth in the groove 701 at the bottom of the cleaning strip 7, so that the cleaning strip 7 will rotate and swing around the limit rod 704. During the rotation and swing of the cleaning strip 7, the cleaning plate 7 will knock on the elastic filter 8, and the filter 8 will vibrate, causing the silicon powder attached to the filter 8 to fall off due to the vibration of the filter 8.
