Description

Technical Field

[0001] The present invention relates to the technical field of beryllium oxide processing, and particularly to a processing device for energy-saving beryllium oxide. Background Art

[0002] Beryllium oxide is a high-quality refractory material with a high melting point (above 2500 °C) and good chemical stability. This enables the refractory ceramic materials made therefrom to have high thermal shock resistance and be widely used in the manufacture of high-temperature components such as crucibles for smelting special metals, special thermocouple protection sleeves, and rocket combustion chamber nozzles. Secondly, its thermal conductivity is not only superior to most non-metallic materials, but even exceeds some metallic materials, while maintaining an extremely low coefficient of thermal expansion. Therefore, even under high-temperature conditions close to the melting point, beryllium oxide can still maintain stable electrical insulation properties. Thus, beryllium oxide is widely used in the electronics industry, mainly for manufacturing insulating heat dissipation plates in electron tubes and transistors. Using such heat dissipation plates can improve the output power and achieve miniaturization.

[0003] In the production process of beryllium oxide, first, the crystal structure of beryllium ore is destroyed by high-temperature roasting, and then the destroyed beryllium ore is acidified with sulfuric acid solution to generate beryllium sulfate. After that, beryllium hydroxide precipitate is obtained through a neutralization reaction, and then the beryllium hydroxide precipitate is dried to obtain beryllium hydroxide. The beryllium hydroxide is decomposed by high-temperature calcination to generate beryllium oxide. The drying of the above beryllium hydroxide is usually processed by a centrifugal spray dryer. The beryllium hydroxide precipitate slurry is centrifugally ejected under pressure through an atomizer, and the ejected atomized particles are dried by hot air to obtain beryllium hydroxide, and then the beryllium hydroxide is sent into a calcination furnace for calcination to generate beryllium oxide. During the drying process of beryllium hydroxide, the water content in the beryllium hydroxide slurry will change, affecting the humidity inside the spray drying device. Insufficient water evaporation leads to incomplete drying and the phenomenon of wet powder sticking to the wall. If the hot air is always at the maximum power for drying, over-drying will occur, resulting in excessive energy consumption.

[0004] In view of this, the present invention provides a processing device for energy-saving beryllium oxide to solve the technical problems existing in the above-mentioned prior art. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a processing device for energy-saving beryllium oxide, having the following beneficial effects: In the present invention, the slurry enters the drying cylinder from the feeding mechanism and the injection mechanism. High-temperature air is introduced into the drying cylinder through the spiral air intake mechanism and the air jet mechanism. The slurry is sprayed out in a spiral shape from the injection mechanism and diffuses in a mist shape in the two layers of high-temperature air. The high-temperature air is used to quickly evaporate the water in the slurry, and the mist-shaped slurry is mixed under the wrapping of the two layers of hot air. When the slurry concentration is stable, the contact between the material and the inner wall of the drying cylinder is reduced, and the risk of wall sticking is lowered. A plurality of buffer tanks are arranged around the drying cylinder in a stepped manner, and a cleaning mechanism is arranged between each pair of buffer tanks. When the water content in the slurry increases, the evaporation amount increases after contacting with the hot air, causing the pressure inside the drying cylinder to rise, squeezing the piston components inside the buffer tank, and then driving the cleaning mechanism to move upward. By using the cleaning mechanism to move on the inner wall surface of the drying cylinder, it is possible to prevent the incompletely dried material from adhering to the inner wall of the drying cylinder and causing wall sticking. When the water content of the slurry is stable, the cleaning mechanism moves downward to reset, forming a scraping and cleaning action on the inner wall of the drying cylinder, so that the peeled wet material contacts the hot air and is dried again. This not only avoids the occurrence of unstable drying caused by changes in the water content of the slurry, but also reduces heat loss and lowers the operating cost of the equipment.

Detailed implementation manners

[0019] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0020] Reference Figures 1-11 , an energy-saving beryllium oxide processing device, including a support frame 1. A feeding hopper 10 is installed in the middle of the support frame 1, and a drying cylinder 9 is installed at the top of the feeding hopper 10. A head 7 is installed at the top of the drying cylinder 9. A spraying mechanism 12 is rotatably installed at the top of the head 7, and a driving motor 6 for driving the spraying mechanism 12 to rotate is installed at the top of the support frame 1. A feeding mechanism 5 is installed at the top of the support frame 1, and the bottom end of the feeding mechanism 5 is rotatably connected to the spraying mechanism 12. An air jetting mechanism 3 is installed in the middle of the drying cylinder 9, and the air jetting mechanism 3 is arranged below the spraying mechanism 12. A sealing cover 4 is installed on the outer side of the top of the head 7, and an air inlet pipe is installed on the side of the sealing cover 4. A three-way solenoid valve and a hot air pipe 2 are installed between the air inlet pipe and the pipe orifice of the air jetting mechanism 3. A spiral air inlet mechanism 15 is installed at the bottom of the head 7, and the top of the spiral air inlet mechanism 15 is communicated with the sealing cover 4. A plurality of groups of symmetrically distributed buffer tanks 8 are arranged on the outer side surface of the drying cylinder 9, and a limiting groove 14 is arranged between the buffer tanks 8 and the drying cylinder 9. A cleaning mechanism 13 is arranged between each group of buffer tanks 8, and the cleaning mechanism 13 is slidably connected with the limiting groove 14.

[0021] In the present invention, the slurry enters the drying cylinder 9 from the feeding mechanism 5 and the spraying mechanism 12. High-temperature air is introduced into the drying cylinder 9 through the spiral air inlet mechanism 15 and the air jetting mechanism 3. The slurry is sprayed out in a spiral shape from the spraying mechanism 12 and diffuses in a mist shape in the two layers of high-temperature air. The high-temperature air is used to quickly evaporate the water in the slurry, and the mist-shaped slurry is mixed under the wrapping of the two layers of hot air. When the slurry concentration is stable, the contact between the material and the inner wall of the drying cylinder 9 is reduced, and the risk of wall sticking is lowered. A plurality of groups of buffer tanks 8 are arranged around the drying cylinder 9 in a stepped distribution, and a cleaning mechanism 13 is arranged between each pair of buffer tanks 8. When the water content in the slurry increases, the evaporation amount increases after contacting with the hot air, causing the pressure inside the drying cylinder 9 to rise, squeezing the piston component inside the buffer tank 8, and then driving the cleaning mechanism 13 to move upward. By using the cleaning mechanism 13 to move on the inner wall surface of the drying cylinder 9, it is possible to prevent the incompletely dried material from adhering to the inner wall of the drying cylinder 9 and causing wall sticking. When the water content of the slurry is stable, the cleaning mechanism 13 moves downward to reset, forming a scraping and cleaning action on the inner wall of the drying cylinder 9, so that the peeled wet material contacts the hot air to achieve re-drying. This not only avoids the occurrence of unstable drying caused by changes in the water content of the slurry, but also reduces heat loss and lowers the equipment operation cost.

[0022] As a further solution in the present invention, the feeding mechanism 5 includes a main feeding pipe 51, and a feeding branch pipe 52 extending into the internal part of the spraying mechanism 12 is arranged at the bottom of the main feeding pipe 51. A boosting motor 53 is installed at the end of the main feeding pipe 51, and a stirring shaft 54 is installed at the end of the output shaft of the boosting motor 53. A plurality of propeller blades 55 are installed on the outer side of the stirring shaft 54. In the present invention, the slurry enters the main feeding pipe 51, and the boosting motor 53 drives the stirring shaft 54 to rotate rapidly, thereby driving the propeller blades 55 to rotate inside the main feeding pipe 51, boosting and stirring the slurry inside the main feeding pipe 51, and enhancing the atomization effect at the outlet of the spraying mechanism 12.

[0023] As a further solution in the present invention, the spraying mechanism 12 includes a vertical conveying pipe 121, and a plurality of helically distributed guide plates 122 are installed at the bottom of the vertical conveying pipe 121. Spray holes 123 are arranged between the guide plates 122. In the present invention, the high-pressure slurry enters the area of the guide plates 122 through the vertical conveying pipe 121, and the driving motor 6 also drives the spraying mechanism 12 to rotate rapidly, forming a centrifugal force outside the spray holes 123, quickly rotating and diffusing the sprayed atomized material, increasing the contact range between the material particles and the hot air, and accelerating the material drying efficiency.

[0024] As a further solution in the present invention, the air jetting mechanism 3 includes an L-shaped jet pipe 31, and a dispersion nozzle 33 is rotatably connected to the top of the jet pipe 31. A triangular support 32 connected to the inner wall of the drying cylinder 9 is arranged on the outer side of the vertical section of the jet pipe 31. In the present invention, a part of the high-temperature air passes through the jet pipe 31 and the dispersion nozzle 33, and diffuses in an umbrella shape below the spraying mechanism 12, cooperating with the spiral air curtain formed by the upper spiral air intake mechanism 15 to wrap the sprayed mist-like material. When the dispersion nozzle 33 rotates under the impact of the air flow, it drives the mist-like material to flow spirally downward, accelerating the material movement speed, improving the material drying efficiency, and preventing the material from staying on the inner wall of the drying cylinder 9 to form wall hanging.

[0025] As a further solution in the present invention, a helically diffused shear blade 34 is arranged on the outer side of the dispersion nozzle 33, and a horizontally distributed shear rod 35 is arranged at the tail end of the shear blade 34. A plurality of air spray holes 36 are arranged on the side surface of the shear blade 34. In the present invention, the high-temperature air sprays out from the air spray holes 36, pushing the dispersion nozzle 33 to rotate and increasing the diffusion range of the hot air. At the same time, by using the rotational movement of the shear blade 34 and the shear rod 35, the passing air flow and material particles are sheared and stirred, further increasing the heat exchange efficiency between the material and the hot air and accelerating the evaporation speed of the moisture in the material.

[0026] As a further solution in the present invention, an annular flow disturbing mechanism 11 is installed inside the blanking hopper 10, and a solenoid valve and a pipeline connected to the hot air pipe 2 are arranged at the bottom of the annular flow disturbing mechanism 11. In the present invention, the annular flow disturbing mechanism 11 is arranged in the blanking hopper 10. During continuous drying operation, part of the high-temperature air is introduced into the annular flow disturbing mechanism 11. By using the instantaneous airflow blowing from the bottom to the top, the air pressure inside the drying cylinder 9 is changed, and the cleaning mechanism 13 inside the drying cylinder 9 is impacted to drive the cleaning mechanism 13 to move up and down, achieving the effect of regularly cleaning the inner wall of the drying cylinder 9.

[0027] As a further solution in the present invention, the annular flow disturbing mechanism 11 includes an annular flow disturbing seat 111 and a flow disturbing air inlet pipe 112 installed on the side surface of the annular flow disturbing seat 111. An activity ring 113 is rotatably installed inside the annular flow disturbing seat 111, and spiral upwardly distributed flow disturbing holes 114 and conically downwardly distributed pressure increasing holes 115 are arranged on the surface of the activity ring 113. In the present invention, when the high-temperature air enters the inside of the annular flow disturbing seat 111, part of the air is ejected from the upper flow disturbing holes 114, contacts and mixes with the materials and air inside the drying cylinder 9, impacts the internal environment of the drying cylinder 9, and drives the activity ring 113 to rotate. Another part of the hot air is concentrated at the outlet pipe position of the blanking hopper 10, accelerating the conveying efficiency of the materials, and thus improving the drying efficiency of the materials.

[0028] As a further solution in the present invention, the spiral air intake mechanism 15 includes an annular air intake cover 152 installed at the bottom of the head 7, and a sector pipe 151 connected to the sealing cover 4 is arranged at the top of the annular air intake cover 152. A plurality of strip-shaped holes 153 are arranged at the bottom of the annular air intake cover 152, and the strip-shaped holes 153 are spirally distributed around the spraying mechanism 12. In the present invention, part of the high-temperature air is sprayed from top to bottom through the annular air intake cover 152. Guided by the spirally distributed strip-shaped holes 153, a columnar air curtain surrounding the spraying mechanism 12 is formed, which collides with the lower-layer hot air diffused in an umbrella shape at the bottom, quickly disperses and heat-exchanges the fog-like materials located between the two layers of hot air, further improving the efficiency of drying and dehydrating the materials.

[0029] As a further solution in the present invention, a linkage ring 156 is rotatably installed inside the annular air inlet hood 152, a driving ring 154 is rotatably installed inside the sealing hood 4, and a linkage rod is installed between the driving ring 154 and the linkage ring 156. A plurality of blocking blocks 157 that are slidably matched with the inner wall of the annular air inlet hood 152 are arranged at the bottom of the linkage ring 156. A stepping motor 155 for driving the driving ring 154 to rotate is installed inside the sealing hood 4. In the present invention, the stepping motor 155 drives the driving ring 154 and the linkage ring 156 to perform a reciprocating rotational motion of ±30° inside the annular air inlet hood 152. The blocking blocks 157 slide along the inner wall of the annular air inlet hood 152, thereby orderly blocking some of the strip-shaped holes 153 through the blocking blocks 157, changing the impact direction of the upper-layer hot air, and further forming a violent impact on the upper layer of the drying cylinder 9, further accelerating the movement speed between the material and the hot air, and accelerating the heat exchange efficiency between the material and the hot air.

[0030] As a further solution in the present invention, the cleaning mechanism 13 includes a cleaning ring 134 and two cylinders 131 installed inside the buffer tank 8. A spring 132 is installed inside the cylinder 131, and a sealing piston 133 is installed at the bottom of the spring 132. The sealing piston 133 is fixedly connected to both ends of the cleaning ring 134. In the present invention, when the pressure inside the drying cylinder 9 is stable, the sealing piston 133 is at a fixed height inside the cylinder 131. When the air pressure inside the drying cylinder 9 changes due to the influence of the moisture content of the material or the pressure of the high-temperature air, the bottom pressure borne by the sealing piston 133 changes accordingly, driving the cleaning ring 134 to move up and down. The cleaning ring 134 fits the inner wall of the drying cylinder 9 and cleans the material on the inner wall surface of the drying cylinder 9 during the movement. The peeled-off material is scattered and dried by the impact of the high-temperature air, avoiding the phenomenon of material wall hanging.

[0031] During use, the slurry enters the drying cylinder 9 from the feeding mechanism 5 and the spraying mechanism 12. High-temperature air is introduced into the drying cylinder 9 through the spiral air intake mechanism 15 and the air jet mechanism 3. The slurry is sprayed out in a spiral shape from the spraying mechanism 12 and diffuses in a mist shape in the two layers of high-temperature air. The high-temperature air is used to quickly evaporate the moisture in the slurry, reducing the contact between the material and the inner wall of the drying cylinder 9 and lowering the risk of wall sticking. Multiple sets of buffer tanks 8 are arranged around the drying cylinder 9 in a stepped distribution, and a cleaning mechanism 13 is arranged between each pair of buffer tanks 8. During the drying process of the slurry, the sealing piston 133 is affected by the internal pressure of the drying cylinder 9 and squeezes the spring 132, thereby driving the cleaning ring 134 to move upward and be in a floating state. When the water content in the slurry increases, the evaporation amount increases after contacting with the hot air, causing the internal pressure of the drying cylinder 9 to rise, squeezing the piston component inside the buffer tank 8, and then driving the cleaning mechanism 13 to move upward. The cleaning mechanism 13 is used to move on the inner wall surface of the drying cylinder 9 to prevent incompletely dried materials from adhering to the inner wall of the drying cylinder 9 and causing wall sticking. When the water content of the slurry is stable, the cleaning mechanism 13 moves downward to reset and forms a scraping and cleaning action on the inner wall of the drying cylinder 9.

[0032] The above is only a preferred specific embodiment 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, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
