Description

Technical Field

[0001] The invention relates to the technical field of gaseous medium drying, in particular to a high-purity quartz sand surface-coated spray drying device. Background Art

[0002] High-purity quartz sand refers to quartz sand with extremely high purity. Its main component is silicon dioxide. It has extremely high purity and has the advantages of high heat resistance, low expansion coefficient, good chemical inertness and electrical insulation. It is widely used in high-end industries such as semiconductors, optical communications, and photovoltaics. The operation method is: by uniformly coating a layer of functional material on the surface of quartz sand particles to improve its surface properties, the coating material is made into a liquid or slurry, and dispersed into fine droplets through an atomizer. It comes into contact with a hot gaseous medium, and the solvent in the droplets evaporates rapidly. The coating material is deposited on the surface of the quartz sand in solid form, and the drying process is completed at the same time.

[0003] In the prior art, when high-purity quartz sand is sprayed for surface coating, if the droplet size is too large, the surface solvent evaporates faster than the internal part, which will cause the outside to solidify into a shell first, and the internal solvent will remain or not dry thoroughly, thus agglomerating to form dry balls. The agglomerated dry balls are easily mixed with the quartz sand. However, the current coating device rotates slowly, and it is impossible to break the dry balls in time through mechanical force, which affects the uniformity of the particle size distribution of the quartz sand and makes it difficult for the quartz sand to be fully coated.

[0004] Therefore, we proposed a high-purity quartz sand surface-coated spray drying device to solve the above-mentioned problems. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When in use, the driving motor is started to rotate the drying drum. When the positive magnetic strip fixed on the surface of the first spring plate rotates to the positive magnetic block, the positive magnetic strip fixed on the surface of the second spring plate corresponds to the negative magnetic block. The first spring plate will pop out toward the inside of the drying drum, and the second spring plate will pop out toward the outside of the drying drum. When the drying drum rotates slowly, the pop-up directions of the first spring plate and the second spring plate will change, thereby continuously bouncing up the quartz sand inside it, increasing the contact area between the quartz sand and the coating material, thereby achieving a better coating effect of the quartz sand. At the same time, the dry balls formed by agglomeration in the gas are also continuously bouncing up. The dry balls collide with the frame structure of the shear frame and become small particles, which are sieved out when they reach the screening net.

[0018] 2. When in use, the air pump is started to deliver heated gas into the air injection chamber, thereby drying the spray on the surface of the quartz sand particles. The air injection chamber disperses the heated gas into the interior of the drying drum. The liquid spray contacts the hot air, and the solvent in the droplets evaporates quickly. The coating material is deposited on the surface of the quartz sand in a solid form, and the drying process is completed at the same time.

[0019] 3. When in use, the coating material is made into liquid and stored in the liquid storage tank. By starting the liquid pump, the liquid coating material is transported to the inside of the spray chamber, so that the liquid coating material is sprayed obliquely downward from the higher end of the drying drum in the form of mist. When the drying drum is not started, high-purity quartz sand particles can be injected into the drying drum through the opening area of ​​the feed baffle to perform spray drying coating operation.

A fixing port 309 is provided on the outer surface of one end of the first spring plate 306, and a screen mesh 303 is fixedly connected to the inner wall of the fixing port 309. A discharge port 302 is provided on the outer surface of one end of the drying drum 301. Each first spring plate 306 and each second spring plate 307 are arranged adjacent to each other, and the number and position of the positive magnetic block 204 and the negative magnetic block 205 correspond to the number and position of the multiple positive magnetic strips 308. The position and inner diameter of the screen mesh 303 match the position and inner diameter of the discharge port 302. Component 1 includes two supporting bases 101, a plurality of connecting rods 102 are fixedly connected between the two supporting bases 101, two supporting frames 104 are fixedly connected between the tops of the two supporting bases 101, the two supporting frames 104 have different heights, and the two supporting frames 104 are used to keep the drying drum 301 tilted, the tops of the two supporting frames 104 are fixedly connected with support rings 105, the drying drum 301 rotates on the inner walls of the two supporting rings 105, the inner walls of the two supporting rings 105 are provided with rotation grooves 106, the inner walls of the two rotation grooves 106 are movably connected with a plurality of rollers 108, and the rollers 108 are used to reduce the friction generated when the drying drum 301 rotates Friction, the inner walls of the two rotating grooves 106 are provided with a limiting ring frame 107, and the limiting ring frame 107 is used to limit the roller 108, the outer surface of the drying drum 301 is fixedly connected to the driven rotating ring 206, and the outer surface of one of the support rings 105 is provided with a driving motor 208, and the output shaft of the driving motor 208 is fixedly connected to the driving turntable 207, and the outer surface of the driving turntable 207 is movably connected to the outer surface of the driven rotating ring 206, and a group of reinforcing rods 202 are fixedly connected at both ends of the fixed cylinder 201, and the two groups of reinforcing rods 202 are respectively fixedly connected to the opposite sides of the two support rings 105, and a support plate 103 is fixedly connected between the tops of the two supporting base frames 101.

[0034] In this embodiment, when in use, the driving motor 208 is started to rotate the driving turntable 207. Due to the friction between the driving turntable 207 and the driven rotating ring 206, when the driving turntable 207 rotates, the driven rotating ring 206 and the drying drum 301 rotate simultaneously. At this time, the outer surface of the drying drum 301 is in close contact with the rollers 108 inside the two support rings 105. Therefore, the drying drum 301 can rotate inside the two support rings 105. Under the action of gravity, the quartz sand inside the drying drum 301 will slowly move downward during the rotation. During this process, the positive magnetic block 204 and the negative magnetic block 205 fixedly mounted inside the fixed cylinder 201 do not move, while the positive magnetic strips 308 fixed on the surface of the first spring plate 306 and the second spring plate 307 rotate with the rotation of the drying drum 301. When the positive magnetic strips 308 fixed on the surface of the first spring plate 306 rotate to the positive magnetic block 204, under the principle of magnetic like poles repel, all the first spring plates 306 will pop out to the inside of the drying drum 301, and at the same time, all the positive magnetic strips 308 fixed on the surface of the second spring plate 307 will be The negative magnetic block 205, under the principle of magnetic opposite poles attracting each other, all the second spring plates 307 will pop out toward the outside of the drying drum 301. When the drying drum 301 drives the first spring plate 306 and the second spring plate 307 to rotate slowly, the first spring plate 306 will rotate to the positive magnetic block 204, and the second spring plate 307 will rotate to the negative magnetic block 205. Then the originally attractive magnetic poles are converted into repulsive poles, and the repulsive magnetic poles are converted into attractive poles. The pop-up directions of the first spring plate 306 and the second spring plate 307 are also changed. Therefore, when the drying drum 301 is continuously rotating, the first spring plate 306 and the second spring plate 307 are ejected. During rotation, the first spring plate 306 and the second spring plate 307 continuously bounce up the quartz sand inside, thereby increasing the contact area between the quartz sand and the coating material, thereby enabling a better coating effect of the quartz sand. While the quartz sand is continuously bouncing up, the dry balls formed by agglomeration in the gas are also continuously bounced up. The dry balls collide with the frame structure of the shearing frame 305 and become small particles. When they reach the screening net 303, they are sieved down, and the coated quartz sand is discharged from the lower end of the drying drum 301. Two spaces are provided in the receiving box 6 for receiving quartz sand and dry ball small particles respectively.

The output end of the air pump 406 is fixedly connected to an air delivery pipe 407, and an electric heating coil 405 is provided at one end of the air delivery pipe 407. One end of the electric heating coil 405 is fixedly connected to the air injection cavity 403, and the carrier 404 is used to support the electric heating coil 405. The air injection cavity 403 The outer surface of the drying drum 301 is fixedly connected to a first fixed bearing 402, and the outer surface of the first fixed bearing 402 is fixedly connected to a material unloading baffle 401, which is fixedly installed at one end of the drying drum 301, and the opening area of ​​the material unloading baffle 401 is used for unloading, and a material receiving box 6 is fixedly connected between the tops of the two supporting base frames 101 near the air inlet assembly 4, and the two partitions of the material receiving box 6 are respectively used to receive materials discharged from the discharge port 302 and the material unloading baffle 401, and a discharge plate 7 is movably installed on one side of the material receiving box 6, wherein, when the material unloading baffle 401 rotates with the drying drum 301, the air injection cavity 403 is stable and motionless.

[0036] In this embodiment, when in use, by installing the discharge baffle 401 at the downward end of the drying drum 301, when the drying drum 301 rotates, the opening area of ​​the discharge baffle 401 is used to discharge the quartz sand particles coated by the spray, and by starting the air pump 406 to pressurize the gas, the gas is transported to the gas injection chamber 403 through the gas pipe 407.

[0038] In this embodiment, when in use, a layer of functional material, such as metal oxide, ceramic powder, high molecular polymer, etc., is uniformly coated on the surface of the quartz sand particles to improve their surface properties, such as wear resistance, corrosion resistance, conductivity, interface bonding strength, etc., and the coating material is made into liquid and stored in the liquid storage tank 501. By starting the liquid pump 503 to pressurize it, the liquid coating material stored in the liquid storage tank 501 is pumped out through the liquid infusion pipe 508, and then transported to the inside of the spray chamber 505 through the output pipe 504 and the spray chamber 505. The spray nozzle of the spray chamber 505 adopts an atomizing nozzle, so that the liquid coating material is sprayed obliquely downward from the higher end of the drying drum 301 in the form of mist. When the drying drum 301 is not started, the high-purity quartz sand particles can be injected into the drying drum 301 through the opening area of ​​the feed baffle 507, thereby performing the spray drying coating operation.

[0039] The method of use and working principle of this device: When in use, a layer of functional materials, such as metal oxides, ceramic powders, high molecular polymers, etc., is uniformly coated on the surface of quartz sand particles to improve their surface properties, such as wear resistance, corrosion resistance, conductivity, interface bonding strength, etc. The coating material is made into liquid and stored in the liquid storage tank 501. By starting the liquid pump 503 to pressurize it, the liquid coating material stored in the liquid storage tank 501 is extracted through the liquid infusion pipe 508, and then transported to the inside of the liquid spray chamber 505 through the output pipe 504 and the liquid spray chamber 505. The spray nozzle of the liquid spray chamber 505 adopts an atomizing nozzle, so that the liquid coating material is sprayed obliquely downward in the form of mist from the higher end of the drying drum 301. When the drying drum 301 is When the operation is not started, high-purity quartz sand particles can be injected into the drying drum 301 through the opening area of ​​the feed baffle 507, so as to perform the spray drying coating operation. At the same time, by installing the discharge baffle 401 at the obliquely downward end of the drying drum 301, when the drying drum 301 rotates, the opening area of ​​the discharge baffle 401 is used to discharge the spray-coated quartz sand particles. By starting the air pump 406 to pressurize it, the gas is transported to the gas injection cavity 403 through the gas pipe 407. In this process, it passes through the electric heating coil 405. By turning on the electric heating coil 405, the turned-on electric heating coil 405 will quickly heat the gas transported out of the gas pipe 407, thereby heating the gas to a temperature suitable for drying the quartz sand particles. Temperature, the air injection nozzle of the air injection chamber 403 adopts an atomizing nozzle, which can disperse the heated gas into the interior of the drying drum 301, the liquid spray contacts the hot air, the solvent in the droplets evaporates quickly, and the coating material is deposited on the surface of the quartz sand in a solid form, and the drying process is completed at the same time. When in use, by starting the driving motor 208, the driving turntable 207 can be rotated. Due to the friction between the driving turntable 207 and the driven rotating ring 206, when the driving turntable 207 rotates, the driven rotating ring 206 and the drying drum 301 will rotate at the same time. At this time, the outer surface of the drying drum 301 is in close contact with the rollers 108 inside the two support rings 105, so the drying drum 301 can rotate inside the two support rings 105. Under the action of force, the quartz sand inside the drying drum 301 will slowly move downward during the rotation. During this process, the positive magnetic block 204 and the negative magnetic block 205 fixedly installed inside the fixed cylinder 201 do not move, while the positive magnetic strips 308 fixed on the surfaces of the first spring plate 306 and the second spring plate 307 rotate with the rotation of the drying drum 301. When the positive magnetic strips 308 fixed on the surface of the first spring plate 306 rotate to the positive magnetic block 204, under the principle of like magnetic poles repelling each other, all the first spring plates 306 will pop out to the inside of the drying drum 301. At the same time, all the positive magnetic strips 308 fixed on the surface of the second spring plate 307 correspond to the negative magnetic block 205. Under the principle of opposite magnetic poles attracting each other,All the second spring plates 307 will pop out toward the outside of the drying drum 301. When the drying drum 301 drives the first spring plates 306 and the second spring plates 307 to rotate slowly, the first spring plates 306 will rotate to the positive magnetic block 204, and the second spring plates 307 will rotate to the negative magnetic block 205. Then the magnetic poles that originally attracted each other will be converted into repulsive poles, and the magnetic poles that repelled each other will be converted into attractive poles. The pop-up directions of the first spring plates 306 and the second spring plates 307 will also change. As the drum 301 rotates continuously, the first and second spring plates 306 and 307 continuously bounce the quartz sand inside. As the quartz sand is continuously bounced, the dry balls formed in the gas are also continuously bounced. The dry balls collide with the frame structure of the shear frame 305 and become small particles. When they reach the screening net 303, they are screened out. The coated quartz sand is discharged from the lower end of the drying drum 301. The receiving box 6 is provided with two spaces to receive the quartz sand and dry ball small particles respectively.

The model is selected according to the actual use, so the control method and wiring layout of the drive motor 208, electric heating coil 405, air pump 406 and liquid pump 503 will no longer be explained in detail.
