Description

Technical Field

[0001] The invention relates to the technical field of silicon carbide micropowder drying, and in particular to a silicon carbide micropowder drying device and process. Background Art

[0002] The drying process of silicon carbide powder is to remove moisture from the water-containing silicon carbide powder by heating or other means to achieve the required degree of dryness. Silicon carbide is a ceramic material widely used in high temperature, wear resistance, thermal conductivity and other fields. Its powder is usually used in the manufacture of composite materials, coatings, electronic components and other high-performance materials.

[0003] The patent number CN211601445U discloses a recovery and drying device for water used in the production of silicon carbide micropowder, which belongs to the technical field of silicon carbide micropowder devices, and includes a device body, a baffle plate connected to the lower part of the device body. The recovery and drying device for water used in the production of silicon carbide micropowder is provided with a motor, a rotating rod, a connecting rod, a scraper and a placement plate. When a user uses this device to heat and dry the silicon carbide micropowder, the user can add the silicon carbide micropowder into the interior of the device body through a feeding pipe. When the silicon carbide micropowder enters the placement plate inside the device body, the user can start the motor, and after the motor is started, the rotating rod can be driven to rotate, and the rotating rod rotates and then drives the placement plate to rotate, while the connecting rod does not rotate when the placement plate rotates. Therefore, when the placement plate rotates, the connecting rod can flatten the silicon carbide micropowder accumulated in the placement plate through the scraper, thereby avoiding the accumulation of silicon carbide micropowder inside the placement plate, thereby greatly improving the drying efficiency of the device.

[0004] However, the current drying device for silicon carbide micropowder has the following problems: when the recovery and drying device for silicon carbide micropowder production water is in use, the wet silicon carbide micropowder will fall downward in a muddy state, and the muddy silicon carbide micropowder in the middle is not easy to dry, resulting in the problem that the equipment does not thoroughly dry the inside of the silicon carbide micropowder.

[0016] (2) The present invention sets a wire pressing device, an annular cross block, a concave cylinder, a coil rod, a spring, a metal ball, a thin rod and a square block in cooperation with a tamping column. Under the reciprocating extrusion of the metal ball, the alloy wire mesh will produce reciprocating shaking, so that the alloy wire mesh shakes off the silicon carbide micropowder in the mesh seam, thereby preventing the silicon carbide micropowder from being blocked in the mesh seam of the alloy wire mesh and causing the problem of poor separation effect of the alloy wire mesh.

[0017] (3) The present invention sets a corner cleaning device, wherein the U-shaped frame, the shaft plate, the arc-shaped spring piece 1, the inclined plate, the inner groove plate and the round block cooperate with the arc-shaped spring piece 2. The inclined plate shovels out the silicon carbide micropowder at the angle of the alloy wire mesh to prevent the silicon carbide micropowder from accumulating at the angle of the alloy wire mesh and causing damage to the angle of the alloy wire mesh. Moreover, under the elastic force of the arc-shaped spring piece 2, the round block limits the inner groove plate, so that the U-shaped frame on the inner groove plate can move up and down stably, preventing the U-shaped frame from shaking violently and causing the equipment to run unsmoothly.

Ring blocks 214 are fixed on both sides of the outer wall of the round rod 213, and four hole fan plates 215 are embedded in the outer walls of the two ring blocks 214. The outer walls of the four hole fan plates 215 are respectively provided with a plurality of leakage holes , four perforated fan plates 215 are located below the feed port of the furnace body 2. During the reversal of the perforated fan plates 215, the muddy silicon carbide powder falls downward from the feed port on the furnace body 2. The perforated fan plates 215 reverse and slap the muddy silicon carbide powder. The multiple leakage holes of the perforated fan plates 215 slap the muddy silicon carbide powder into small pieces. At the same time, the heating module 3 transfers heat to the alloy wire mesh 212. The small pieces of silicon carbide powder fall downward onto the alloy wire mesh 212. The mesh seams of the alloy wire mesh 212 separate and heat the small pieces of silicon carbide powder, so that the muddy silicon carbide powder is decomposed into small pieces for drying, so as to avoid the situation that when the drying device is drying the muddy silicon carbide powder, the inside of the muddy silicon carbide powder is not easy to dry, resulting in incomplete drying of the inside of the silicon carbide powder by the equipment.

The short columns 222 transmit the vibration to the hole fan plate 215, so that the hole fan plate 215 vibrates and throws off the muddy silicon carbide micropowder, thereby preventing the muddy silicon carbide micropowder from adhering to the hole fan plate 215 when the drying device is drying the muddy silicon carbide micropowder, resulting in poor effect of the equipment in dispersing the muddy silicon carbide micropowder.

At the same time, the resistance heating rod in the heating module 3 starts to heat up, and the resistance heating rod transfers heat to the heat conducting plate, and the heat conducting plate transfers heat to the furnace body 2. The heat in the furnace body 2 transfers the wet silicon carbide micropowder, and the wet silicon carbide micropowder is dried in the furnace body 2. During the drying process of the silicon carbide micropowder, the silicon carbide micropowder When the powder is heated, the hot air will enter the cylinder 4, and the hot air in the cylinder 4 will enter the conduit 5.

The mesh seams of the alloy wire mesh 212 separate and heat the small pieces of silicon carbide powder, so that the muddy silicon carbide powder is decomposed into small pieces for drying, thereby preventing the muddy silicon carbide powder from being difficult to dry when the equipment is in use, thereby avoiding the problem of incomplete drying of the inside of the silicon carbide powder by the drying device due to the difficulty in drying the muddy silicon carbide powder.

[0023] When the round rod 213 is reversed in the furnace body 2, the round rod 213 drives the coil 221 to reverse, and the coil 221 drives the short column 222 to reverse.

Under the elastic force of the arc-shaped spring pieces 97, the round blocks 96 limit the inner groove plate 95, so that the U-shaped frame 91 on the inner groove plate 95 can move up and down stably, so as to avoid the U-shaped frame 91 from vigorous shaking when the drying device is drying the muddy silicon carbide micropowder, causing the equipment to run unsmoothly.

[0028] A drying process of a drying device for silicon carbide micropowder comprises the following steps: S1. The staff starts the heating module 3 on the furnace body 2, opens the furnace cover on the furnace body 2, and pours the wet silicon carbide powder into the furnace body 2 from the feed port on the furnace body 2; S2, the perforated fan plate 215 reverses and hits the muddy silicon carbide powder, and the multiple leakage holes of the perforated fan plate 215 hit the muddy silicon carbide powder into small pieces; S3, the short column 222 transmits vibration to the hole fan plate 215, so that the hole fan plate 215 vibrates and throws off the muddy silicon carbide powder, and the mesh slits of the alloy wire mesh 212 separate and heat the small pieces of silicon carbide powder, so that the muddy silicon carbide powder is decomposed into small pieces for drying; S4. Under the reciprocating extrusion of the metal ball 85, the alloy wire mesh 212 will vibrate back and forth, so that the alloy wire mesh 212 can shake off the silicon carbide powder in the mesh gap; S5, the tamping column 88 hits the edge of the alloy wire mesh 212, and the silicon carbide powder is shaken off the mesh edge of the alloy wire mesh 212; S6, the inclined plate 94 shovels out the silicon carbide powder at the angle of the alloy wire mesh 212; S7, the round block 96 limits the inner groove plate 95, so that the U-shaped frame 91 on the inner groove plate 95 can move up and down stably; S8. When the temperature of silicon carbide powder rises, the hot air will enter the cylinder 4, and the hot air in the cylinder 4 will enter the conduit 5. The conduit 5 will transport the hot air into the triangular shell 6. The hot air in the triangular shell 6 will form water droplets when cooling. The water droplets in the triangular shell 6 will enter the water outlet pipe 7, and the water outlet pipe 7 will discharge the water for recovery.

[0029] When the round rod 213 drives the coil 221 to reverse, the coil 221 drives the annular cross block 81 to reverse. At the same time, the furnace body 2 supports the concave cylinder 82, the concave cylinder 82 supports the spring 84, and the spring 84 supports the coil rod 83. During the reversal of the annular cross block 81, the raised part of the annular cross block 81 will enter the concave cylinder 82. Under the action of the extrusion force, the raised part of the annular cross block 81 will move downward against the coil rod 83, and the spring 84 on the coil rod 83 will begin to shrink. When the raised part of the annular cross block 81 leaves the coil rod 83, the spring 84 is reset under the action of the elastic force, and the coil rod 83 is The concave cylinder 82 reciprocates up and down, and the disc rod 83 drives the metal ball 85 to reciprocate up and down. The metal ball 85 contacts the alloy wire mesh 212 during the reciprocating movement. Under the reciprocating squeezing of the metal ball 85, the alloy wire mesh 212 will produce reciprocating shaking, allowing the alloy wire mesh 212 to shake off the silicon carbide micropowder in the mesh gap, thereby preventing the silicon carbide micropowder from being blocked in the mesh of the alloy wire mesh 212 when the equipment is in use, thereby avoiding the problem of silicon carbide micropowder being blocked in the mesh gap of the alloy wire mesh 212 when the drying device is drying the muddy silicon carbide micropowder, resulting in poor separation effect of the alloy wire mesh 212.

[0030] When the disk rod 83 moves back and forth up and down in the concave cylinder 82, the disk rod 83 drives the thin rod 86 to move back and forth up and down, the thin rod 86 drives the block 87 to move back and forth up and down, and the block 87 drives the tamping column 88 to move back and forth up and down. In the process of the tamping column 88 moving back and forth up and down, the tamping column 88 will knock on the edge of the alloy wire mesh 212, and the mesh edge of the alloy wire mesh 212 will shake off the silicon carbide micropowder, preventing the silicon carbide micropowder from being blocked at the mesh edge of the alloy wire mesh 212 when the equipment is in use, thereby avoiding the problem that the silicon carbide micropowder is blocked at the mesh edge of the alloy wire mesh 212 when the drying device is drying the muddy silicon carbide micropowder, causing a large amount of silicon carbide micropowder to accumulate at the mesh edge.

[0031] When the disc rod 83 drives the thin rod 86 to move up and down, the thin rod 86 drives the U-shaped frame 91 to move up and down, the U-shaped frame 91 drives the shaft plate 92 to move up and down, the shaft plate 92 drives the arc spring piece 93 to move up and down, and at the same time, the shaft plate 92 drives the inclined plate 94 to move up and down. When the inclined plate 94 moves downward, the inclined plate 94 contacts the alloy wire mesh 212. Under the action of the extrusion force, the shaft plate 92 rotates in the U-shaped frame 91, and the arc spring piece 93 on the shaft plate 92 is deformed. The shaft plate 92 drives the inclined plate 94 to rotate, and the inclined plate 94 shovels out the silicon carbide micropowder at the angle of the alloy wire mesh 212 to prevent the silicon carbide micropowder from accumulating at the angle of the alloy wire mesh 212 when the equipment is in use, thereby avoiding the problem that the silicon carbide micropowder accumulates at the angle of the alloy wire mesh 212 when the drying device is drying the muddy silicon carbide micropowder, causing the angle of the alloy wire mesh 212 to be damaged.

[0032] While the thin rod 86 drives the U-shaped frame 91 to move back and forth up and down, the U-shaped frame 91 drives the inner groove plate 95 to move back and forth up and down, and the inner groove plate 95 moves back and forth up and down on the round block 96. The inner groove plate 95 drives the arc-shaped spring piece 2 97 to move back and forth up and down, and the arc-shaped spring piece 2 97 produces reciprocating deformation. Under the elastic force of the arc-shaped spring piece 2 97, the round block 96 limits the inner groove plate 95, so that the U-shaped frame 91 on the inner groove plate 95 can move up and down stably, preventing the U-shaped frame 91 from shaking violently when the equipment is in use, thereby avoiding the problem of the drying device running unsmoothly due to the violent shaking of the U-shaped frame 91 when the drying device is drying the muddy silicon carbide micropowder.
