Description

Technical Field

[0001] The invention relates to the technical field of silicon micropowder production, in particular to a device for cleaning and purifying molten silicon micropowder. Background Art

[0002] Silica powder is a non-toxic, odorless, pollution-free inorganic non-metallic material. Due to its excellent properties such as good temperature resistance, acid and alkali corrosion resistance, high thermal conductivity, high insulation, low expansion, stable chemical properties, and high hardness, it is widely used in chemical industry, electronics, integrated circuits, electrical appliances, plastics, coatings, high-grade paints, rubber, national defense and other fields. With the rapid development of high technology, silica powder will also enter a new historical development period.

[0003] In the prior art, a molten silicon micropowder cleaning and purification device disclosed in Chinese patent publication number CN208327403U includes a main body, a plurality of sleeved filter cylinders are provided in the main body, a hollow rotating shaft is provided in the middle of the filter cylinder for rotation, the top of the hollow rotating shaft extends to the outside of the main body and is connected to a feed hopper, a bevel gear 1 is provided on the side wall of the middle of the hollow rotating shaft, a plurality of horizontal shafts are provided for rotation between the filter cylinders, a bevel gear 2 is provided at one end of the horizontal shaft for meshing with the bevel gear 1, a plurality of blade plates are provided on the horizontal shaft corresponding to each filter cylinder, a reflux pipe connected to the feed hopper is provided on both sides of the bottom of the main body, a reflux channel is provided between the reflux pipe and the side wall of the main body, and a collection box is connected at the lower end of the reflux channel.

[0004] However, the above patents have the following deficiencies:

[0005] Since silicon micropowder has stable chemical properties and multiple resistances, it can be used in many fields. The preparation process of silicon micropowder requires the completion of steps such as crushing, screening and grinding. When multiple steps are completed, the powder obtained is easily mixed with impurities, which affects the preparation of subsequent coatings. Therefore, the powder needs to be cleaned and purified before use to ensure the quality of subsequent products. The equipment involved in the above patent can obtain high-purity silicon micropowder of different particle sizes at the same time by graded powder cleaning and utilizing the different pore sizes of multiple filter plates. However, there are still some shortcomings. The powder particles after grinding are small and of low quality. The equipment has a loose structure and poor coordination of components during operation. When the powder is cleaned and screened, the total amount of powder consumed is high, and a large amount of usable powder is easily screened out, resulting in serious waste of raw materials.

[0006] Therefore, we proposed a molten silicon micropowder cleaning and purification device to solve the above problems. Summary of the Invention

By turning on the first driving motor 212, each fine-pore sieve bucket 208 can be evacuated from the interior of the external protective shell 1, thereby facilitating the cleaning of the interior of the fine-pore sieve bucket 208.

[0040] according to Figure 4 As shown, the outer wall of each linkage rod 203 is fixedly provided with a driven roller 204, a first grafting plate 214 is fixedly installed on one side of the outer wall of the upper support plate 201, a second positioning plate 215 is fixedly installed on the top of the first grafting plate 214, a second driving motor 216 is provided inside the second positioning plate 215, a transmission rod 217 is fixedly installed on the output end of the second driving motor 216, and an outer wall of the transmission rod 217 is fixedly provided with an active roller 218, the active roller 218 and a group of slave rollers are fixedly provided. A belt 219 is movably provided between the inner surface walls of the driven roller 204. By arranging the driven roller 204 and the driving roller 218, when the second drive motor 216 is turned on, the driving roller 218 connected thereto rotates at a uniform speed, and under the pull of the belt 219, each driven roller 204 is gradually rotated synchronously, forcing each fine-pore sieve bucket 208 to rotate in the direction of rotation of the driven roller 204, so that the powder in each fine-pore sieve bucket 208 can be fully disturbed by the hot steam in the later stage.

[0041] according to Figure 7 As shown, a third grafting plate 303 is fixedly installed on the front surface of the external protective shell 1, and a group of locking rings 304 are fixedly installed inside the third grafting plate 303. A booster pump 305 is fixedly inserted into the inner surface wall of the group of locking rings 304. The booster pump 305 is provided to increase the air pressure of the hot steam entering the next stage, ensuring that the steam can be sprayed onto each fine-pore screen bucket 208 at high speed and gradually combined with the outer layer of powder.

[0042] according to Figure 3 、 Figure 7 and Figure 8 As shown, an energy storage box 309 is fixedly installed on the front surface of the external protective shell 1, and an insulation interlayer 310 is installed between the inner liner and the inner surface wall of the energy storage box 309. A group of primary air supply pipes 314 are fixedly connected to the top of the water supply tank 302. The exhaust end of each primary air supply pipe 314 is respectively connected to the input end of the booster pump 305. The output end of a group of booster pumps 305 is fixedly connected to a secondary air supply pipe 315. The exhaust end of a group of secondary air supply pipes 315 passes through the energy storage box 3 09, and is connected to the interior of the energy storage box 309. The rear surface of the energy storage box 309 is fixedly connected with a connecting pipe, and the exhaust end of the connecting pipe passes through the outer wall of the junction box 312 and is connected to the interior of the junction box 312.

When the hot steam enters the energy storage box 309, the heat loss can be effectively prevented, so as to accelerate the rate of combination of water vapor and powder.

[0043] according to Figure 1 and Figure 9 As shown, the pushing mechanism 4 includes a group of fourth grafting plates 401, and the number of a group of fourth grafting plates 401 is equal to the fine-pore screen bucket 208. The outer wall of each fourth grafting plate 401 is fixedly installed on the inner wall side of the external protective shell 1, and a locking frame 402 is fixedly installed on the top of each fourth grafting plate 401. A pneumatic push rod 403 is fixedly installed inside each locking frame 402. A limiting sleeve is fixedly installed on the bottom of each pneumatic push rod 403, and the axial end of each pneumatic push rod 403 is respectively placed inside the limiting sleeve. By setting the limiting sleeve, since the axial end of each pneumatic push rod 403 is independently suspended and equipped with multiple cooperative components, the axial end will shake left and right during the extension and retraction process. The limiting sleeve is used to limit the orientation of the axial end to ensure the stability of the pneumatic push rod 403 during operation.

[0044] according to Figure 5 and Figure 6 As shown, the shaft end of each pneumatic push rod 403 is fixedly sleeved with an extension frame 404, the top of each extension frame 404 is welded with a spacing joint 405, the interior of each spacing joint 405 is provided with a group of arc-shaped sleeves 406, and the inner surface wall of each arc-shaped sleeve 406 is fixedly installed with a rubber pad 407. By setting the arc-shaped sleeves 406, since the material of the fine-pore screen bucket 208 itself has ductility, its size is affected by the amount of fine powder it carries. When each group of arc-shaped sleeves 406 is fully closed, the connected rubber pads 407 are tightly attached to the neck of the fine-pore screen bucket 208, compressing the surface of the fine-pore screen bucket 208 from top to bottom, thereby accelerating the falling of the forming fluid.

[0045] according to Figure 6 As shown, a limit rod 408 is fixedly inserted into the interior of each arc-shaped sleeve 406, and one end of the outer wall of each limit rod 408 is movably inserted into the interior of the spacing joint 405, and a group of metal slide rods 409 are fixedly inserted into the interior of each arc-shaped sleeve 406, and one end of the outer wall of each group of metal slide rods 409 is movably inserted into the interior of the spacing joint 405, and an active spring 410 is movably sleeved on the outer wall of each metal slide rod 409. By arranging the metal slide rods 409 and utilizing the movable connection between the metal slide rods 409 and the spacing joint 405, each group of arc-shaped sleeves 406 has the ability to expand the spacing, so as to adapt to fine-pore sieve buckets 208 of multiple sizes, and the reaction force generated by the compression and stretching of the active spring 410 will reset the arc-shaped sleeve 406, ensuring that the rubber pad 407 can be always attached to the surface of the fine-pore sieve bucket 208.

[0046] according to Figure 1 、 Figure 2 and Figure 3 As shown, the outer wall of the second grafting plate 301 is fixedly mounted on the front surface of the external protective shell 1, an outward-opening window 5 is provided on one side of the outer wall of the external protective shell 1, a flat baffle 6 is placed inside the outward-opening window 5, a recovery box 7 is fixedly mounted on the inner wall of the flat baffle 6, and the recovery box 7 is movably placed inside the external protective shell 1, and a handrail 8 is welded to the outer wall of the flat baffle 6 to determine the connection relationship between the second grafting plate 301 and the external protective shell 1, and the recovery box 7 is provided for recovering the fluid contained in the micropowder in the water.

[0047] The effect achieved by the entire mechanism is as follows: first, the equipment is moved to the designated working area, and the bottom of the external protective shell 1 is fully in contact with the ground, and then the power supply is connected to the equipment to provide energy for the multiple electrical components contained therein. When each mechanism in the equipment is in the initial state, the powder is poured into the fine-pore sieve bucket 208 from the metal sleeve 207 in turn until each fine-pore sieve bucket 208 is filled, and then the high-resistance heating wire 307 in the extended edge 306 is energized. After the current passes through the metal conductor, its own heat will continue to be emitted, and the bottom of the water tank 302 will be baked, heating the clean water inside the water tank 302 and gradually making it boil. The booster pump 305 in each locking ring 304 is further turned on, and the inside The rotation of the impeller will form an adsorption force at the air inlet end of the primary transport pipe 314, extracting the high-temperature steam formed in the upper layer of the water tank 302, and transporting it through the primary transport pipe 314 and the secondary transport pipe 315, first entering the interior of the energy storage tank 309, locking the heat of the steam, and then part of the water vapor continues to enter the intersection box 312 through the transport of the connecting pipe, causing the internal air pressure to gradually increase, and part of the water vapor is squeezed into each spray gun 313, and then compressed at the nozzle of the spray gun 313, and sprayed at high speed to the surface of each fine-pore sieve bucket 208. At the same time, the second drive motor 216 in the second positioning plate 215 is turned on, and acts on the transmission rod 217 to make the active roller 218 rotate at a uniform speed. Subsequently, on the belt The pull of 219 causes each driven roller 204 to rotate synchronously, driving the linkage rod 203 to start rotating. Since each U-shaped joint 205 is connected to the linkage rod 203 respectively, each fine-pore sieve bucket 208 also starts to rotate slowly, and the sprayed water vapor evenly covers the surface of each fine-pore sieve bucket 208, gradually soaking the outer layer of the fine-pore sieve bucket 208. Since the silicon powder is insoluble in water, it can be combined with water and floated into the water molecules. Under the action of gravity, the fluid carrying the powder falls to the bottom of the external protective shell 1 and is recovered to the inside of the recovery box 7. During the process, when the water vapor soaks the powder for a period of time, the second drive motor 216 is turned off to stop the rotation of each fine-pore sieve bucket 208, and the locking frame 4 is opened. The pneumatic push rod 403 in 02 extends its shaft end downward and acts on the extension frame 404 and its connected parts. Since each set of rubber pads 407 is at the neck end of the fine-pore screen bucket 208, the downward movement will squeeze the middle of the fine-pore screen bucket 208, and the fluid integrated into the inside of the fine-pore screen bucket 208 will be squeezed out, thereby achieving the purpose of accelerating the descent of the fluid. After repeating the above steps to fully process the powder in each fine-pore screen bucket 208, the relevant driving components in the equipment are turned off in turn, and then the first drive motor 212 is turned on and acts on the solid base 210, driving the load-bearing frame 213 and its connected parts to start turning, evacuating each fine-pore screen bucket 208 from the interior of the external protective shell 1, and cleaning the residue in each fine-pore screen bucket 208.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
