[0002] In the existing production process of silicon materials, silicon dioxide is usually used as a raw material for processing. Among them, after the silicon dioxide powder is washed, the wet silicon dioxide powder needs to be placed in a dryer for drying.

[0022] Furthermore, in order to prevent the silica powder in the drum 3 from entering the ventilation rod 7, a rubber valve 209 is fixedly connected to each air blowing hole 7002.

[0023] Furthermore, in order to remove the iron filings impurities contained in the silica raw material, the first filter screen 6 is made of a magnetic elastic body, specifically a composite material obtained by dispersing iron powder in silicone rubber; an electromagnet is installed inside the fixing rod 5, and the electromagnet is connected to the first filter screen 6.

[0024] Furthermore, in order to ensure the air pressure balance inside the drum 3, an exhaust passage 4003 is opened on the left sealing cover 4; the exhaust passage 4003 is communicated with an external air extraction device.

[0025] It further includes a second filter screen 301; the second filter screen 301 is fixedly connected to the exhaust passage 4003.

[0026] The following is a detailed description of the drying process of the wet silica powder: First, control the electric control rotating plate 4002 on the left sealing cover 4 to start working. Taking the view from front to back as a reference, drive the rotating plate to rotate clockwise through the motor, so that the material feeding port 4001 is communicated with the inside of the drum 3. Then pour the wet silica powder into the material feeding port 4001 of the left sealing cover 4, so that the silica powder enters the left side inside the drum 3. At the same time, control the electric rotating roller 2 to start working. Taking the view from left to right as a reference, drive the rotating roller to rotate counterclockwise through the motor. In this way, through the gear meshing transmission between the electric rotating roller 2 and the drum 3, the drum 3 and the lifting plate 3001 inside rotate clockwise. Since the lifting plate 3001 is arranged obliquely along the length direction with the axial direction of the drum 3, the silica powder on the left side inside the drum 3 is transmitted to the right side through the continuous rotation of the lifting plate 3001 until all the wet silica powder enters the inside of the drum 3. Then control the electric control rotating plate 4002 in the left sealing cover 4 to close, so as to complete the feeding of the silica powder. Subsequently, through the work of the electric control heating wire inside the drum 3, the temperature inside the drum 3 gradually rises, and the wet silica powder inside the drum 3 is dried by high temperature. At the same time, the silica powder is continuously lifted by the lifting plate 3001 to increase the contact area between the silica powder and the air inside the drum 3. As the lifting plate 3001 continuously transmits the silica powder to the right, the silica powder accumulated on the right side inside the drum 3 is more than that accumulated on the left side, which is not conducive to the drying of the silica powder. Therefore, taking the view from left to right as a reference, when the drum 3 continuously rotates clockwise for a preset time, then control the drum 3 and the lifting plate 3001 to rotate counterclockwise for a preset time. In this way, the silica powder can be guided to the left side through the lifting plate 3001, so as to avoid serious accumulation of the silica powder on the right side. Then control the drum 3 to continue to rotate clockwise. In this way, the silica powder can be evenly distributed inside the drum 3 to improve the drying effect. During this process, the wet silica powder is prone to caking during the drying process, and the moisture inside the caking is difficult to disperse, so more time is required to dry the caked silica, thus reducing the drying efficiency of the silica and the drying energy efficiency ratio. At this time, the first filter screen 6 is in a concave arc shape. When the lifting plate 3001 lifts the silica powder, the caking in the silica powder is screened through the first filter screen 6. The silica powder in a dispersed state passes through the mesh holes of the first filter screen 6 and falls back to the bottom of the drum 3, while the caked silica powder is intercepted on the upper surface of the first filter screen 6, and the caked silica powder is converged in the middle of the first filter screen 6 through the concave arc. And at this time, the ventilation rod 7 is located above the caked silica powder, and control the external blowing device to transport high-pressure gas into the ventilation rod 7, so that the high-pressure gas sequentially passes through the air blowing holes 7002 and the rubber valve 209, and the high-pressure gas blows downward to the caked silica powder, and the caked silica powder is dispersed by the high-pressure gas to facilitate the dispersion of the moisture inside the caking, thereby improving the drying efficiency of the silica powder.On this basis, the peripheral blowing device can be controlled to convey high-temperature high-pressure gas into the ventilation rod 7. In this way, while the gas disperses the silicon dioxide powder, the agglomerated silicon dioxide powder is additionally dried by the high temperature, accelerating the drying speed of the agglomerated silicon dioxide powder. On this basis, the peripheral air extraction device is used to extract air from the exhaust passage 4003, so that the air in the drum 3 is discharged outward, thus ensuring the air pressure balance in the drum 3. At the same time, the second filter screen 301 intercepts the silicon dioxide powder in the air to prevent the silicon dioxide powder from being discharged through the exhaust passage 4003. It should be noted here that the rubber valve 209 only allows the gas inside the ventilation rod 7 to blow outward, and blocks the silicon dioxide powder in the drum 3 from entering the inside of the ventilation rod 7, thus preventing the silicon dioxide powder from blocking the inside of the ventilation rod 7.,

[0027] During the continuous drying of the silicon dioxide powder by the drum 3, the driving parts 201 at both ends of the same fixed rod 5 are controlled to move back and forth reciprocally, so that the fixed rod 5 moves back and forth reciprocally, and then the first filter screen 6 shakes continuously, accelerating the speed at which the dispersed silicon dioxide powder falls off the first filter screen 6, thereby improving the efficiency of the first filter screen 6 in screening the agglomerated silicon dioxide powder. It should be noted here that when the first slide plate 5001, the second slide plate 7001 and the third slide plate 206 slide on the sealing cover 4, the connected folding film 208 is stretched and folded adaptively, thus ensuring the sealing performance of the sealing cover 4 and preventing the silicon dioxide powder and air in the drum 3 from overflowing to the outside.,

[0028] When the initial moisture content of the silicon dioxide powder to be dried is relatively high, the silicon dioxide powder is in a paste state, and the paste-like silicon dioxide powder usually has difficulty passing through the first filter screen 6, causing a large amount of silicon dioxide powder to accumulate on the surface of the first filter screen 6, resulting in a low drying efficiency. Thus, when the initial moisture content of the silicon dioxide powder is relatively high, the first electric slider 203 and the second electric slider 204 are controlled to move upward on the slide rail 202, so as to synchronously drive the ventilation rod 7, the baffle 205 and their connecting parts to move upward. Based on the view from left to right, the electric motor 207 is controlled to drive the sleeve shaft 20601 to rotate. Since the rotating shaft 20501 is inserted into the sleeve shaft 20601, the rotating shaft 20501 and the baffle 205 are driven to rotate clockwise, making the convex arc of the baffle 205 face upward. As the baffle 205 moves upward, the middle of the first filter screen 6 is lifted, making the first filter screen 6 in a convex arc shape with the middle high and both sides low. In this way, the convex arc guides the silicon dioxide powder to slide down to the front and rear sides of the first filter screen 6, thus preventing the silicon dioxide powder from accumulating on the surface of the first filter screen 6 and ensuring the drying efficiency of the silicon dioxide powder.,

[0029] On this basis, since the silica raw material usually contains iron filings impurities when broken, the silica powder needs to be additionally de-ironed after drying. For this purpose, the electromagnet inside the fixed rod 5 is controlled to be energized. Since the first filter screen 6 is made of a magnetic elastomer, the magnetic field generated by the electromagnet can magnetize the first filter screen 6. In this way, when the silica powder passes through the first filter screen 6, the iron filings doped in the silica powder are adsorbed by the first filter screen 6. Thus, while the silica powder is being dried, the separation between the silica powder and the iron filings is achieved, eliminating the need for an additional de-ironing operation process, reducing the processing cost of the silica powder. When the silica powder is dried, at this time, more iron filings are adsorbed on the first filter screen 6. Control the first electric slider 203 to drive the ventilation rod 7 to move upward above the fixed rod 5. Subsequently, control the driving member 201 to drive the two fixed rods 5 to move towards each other until they fit together, making the first filter screen 6 in a folded state. At the same time, control the second electric slider 204 to drive the baffle 205 and the third sliding plate 206 to move downward, so that the third sliding plate 206 is located below the middle of the first filter screen 6. Then control the electric motor 207 to drive the sleeve shaft 20601 to rotate, thereby driving the rotating shaft 20501 and the baffle 205 to rotate until the convex arc side of the baffle 205 faces downward. Subsequently, control the electromagnet inside the fixed rod 5 to be de-energized, so that the first filter screen 6 loses its magnetism, and control the driving member 201 to drive the fixed rod 5 to move back and forth continuously, causing the first filter screen 6 to vibrate. In this way, the iron filings adsorbed on the first filter screen 6 fall downward onto the upper surface of the baffle 205. The separated iron filings impurities are collected through the baffle 205. Subsequently, after the drum 3 stops working, the fixed block 20502 and the baffle 205 can be manually pulled out to the right from the third sliding plate 206 on the right sealing cover 4, and at the same time, the rotating shaft 20501 is separated from the sleeve shaft 20601 until the baffle 205 is completely pulled out of the drum 3, and the iron filings collected on the baffle 205 can be cleaned up. Subsequently, the baffle 205 is reinserted into the drum 3 and restored to the initial position for collecting subsequent iron filings.

[0030] As the drum 3 continuously tumbles and dries the silica powder, when the silica powder is dried, control the electric control rotating plate 4002 on the right sealing cover 4 to rotate. Taking the front-to-back view as a reference, make the right electric control rotating plate 4002 rotate counterclockwise, so that the inside of the drum 3 is communicated with the feeding port 4001 of the right sealing cover 4. Taking the left-to-right view as a reference, and control the drum 3 and the lifting plate 3001 to continue rotating clockwise, so that the lifting plate 3001 continuously transports the silica powder to the right to the right feeding port 4001, thus completing the discharging. Embodiment 2

[0031] On the basis of Embodiment 1, as Figure 2 and Figure 4As shown, it further includes a scraper 302; the scraper 302 is fixedly connected to the second left slide plate 7001.

[0032] Furthermore, the scraper 302 is arranged to be inclined downward, and the scraper 302 is arranged to be located above the first filter screen 6.

[0033] During the drying process of the silica powder, the moisture in the silica powder gradually turns into water vapor, which causes the humidity in the drum 3 to be too high. To avoid the high humidity affecting the drying efficiency of the silica powder, an external air extraction device is used to extract air from the exhaust passage 4003, so that the air in the drum 3 carrying water vapor is discharged from the exhaust passage 4003. In this way, the air humidity in the drum 3 can be reduced, thereby improving the drying efficiency of the silica powder. During this process, silica powder is likely to adhere to the second filter screen 301, and since water vapor continuously passes through the second filter screen 301, the silica powder on the second filter screen 301 is likely to agglomerate and harden, which may cause the second filter screen 301 to be blocked. For this reason, the first electric slider 203 can be controlled to drive the second slide plate 7001 to move upward, thereby driving the scraper 302 on the front second slide plate 7001 to scrape the surface of the second filter screen 301 upward. In this way, the agglomerated silica powder on the surface of the second filter screen 301 can be scraped off, thus avoiding the blockage of the second filter screen 301. At the same time, since the scraper 302 is arranged to be inclined downward, the scraped silica powder slides down along the inclined surface of the scraper 302, thereby guiding the agglomerated and hardened silica powder to fall on the first filter screen 6. In this way, the agglomerated and hardened silica powder can be dispersed through the ventilation rod 7, and then the silica powder on the second filter screen 301 can be recycled and dried, reducing the loss rate of the silica powder.

[0034] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
