Description

Technical Field

[0001] This invention relates to the technical field of aluminum hydroxide flame retardant processing, and in particular to a slurry grinding device and grinding process for processing aluminum hydroxide flame retardant. Background Technology

[0002] Aluminum hydroxide flame retardant is an additive flame retardant whose main component is aluminum hydroxide. Through an endothermic dehydration reaction, aluminum hydroxide releases water vapor, thereby lowering the temperature of the combustion zone and inhibiting the spread of flame. Furthermore, the alumina layer formed at high temperatures effectively isolates oxygen, further enhancing the flame retardant effect. In industries such as plastics, rubber products, coatings, and building materials, aluminum hydroxide flame retardant is widely used as an additive, significantly improving not only the flame retardant properties of products but also the mechanical strength and heat resistance of materials.

[0003] When processing aluminum hydroxide flame retardants, the slurry particles need to be ground to achieve the desired fineness. This grinding process requires a grinding device. However, existing grinding devices often result in the slurry particles remaining on the grinding table after grinding, leading to poor discharge and difficulty in grinding subsequent slurry particles. This affects grinding efficiency and reduces practicality. Summary of the Invention

The drive includes a motor and a reducer, both centrally mounted on the top left side of the processing drum. The motor is located to the left of the reducer, and the input is on the right side of the motor. The output end is fixedly connected to the input end of the reducer, and the output end of the reducer is fixedly connected to a drive shaft. The drive shaft is rotatably mounted on the top of the processing barrel, and a transmission gear is fixedly connected to the bottom end of the drive shaft.

[0007] Preferably, a protective cover is detachably installed between the left outer wall of the processing barrel and the left support plate, and the protective cover is fastened to the timing pulley and timing belt.

[0008] Preferably, an observation port is provided on the outer wall of the front of the processing barrel, and an observation window is fixedly installed inside the observation port.

[0009] Preferably, a reinforcing rod is fixedly connected between the inner side of both sets of support plates and the bottom end of the processing barrel.

[0010] This invention also provides the following technical solution: a slurry grinding process for processing aluminum hydroxide flame retardants, the process specifically including the following steps: 1. Start-up: Start the above-mentioned slurry grinding device for processing aluminum hydroxide flame retardant; 2. Feeding: Add slurry particles into the feeding pipe through the feeding hopper, so that the slurry particles fall onto the conical surface of the grinding table through the feeding pipe and the inlet; 3. Grinding: The slurry particles are ground by rotating a turntable and grinding rollers; 4. Discharge: The turntable drives the scraper to scrape the slurry falling to the bottom of the processing tank, scraping the slurry to the discharge port, so that the slurry is discharged through the discharge port and falls onto the receiving hopper, and is discharged through the guide of the receiving hopper.

[0011] Compared with the prior art, the beneficial effects of this invention are as follows: In use, starting the motor not only causes the turntable to rotate, but also allows the striking head to continuously strike the grinding platform. This causes the turntable to drive multiple sets of grinding rollers to rotate around the top conical surface of the grinding platform. Under the action of friction, the grinding rollers rotate on their own axis. Slurry particles are added to the feeding pipe through the feeding hopper, and the slurry particles fall onto the conical surface of the grinding platform through the feeding pipe and inlet. The grinding rollers continuously grind the slurry particles through their own rotation and rotation around the grinding platform, and the striking head... Continuous hammering causes vibration on the outside of the grinding table. This vibration shakes off the slurry particles that remain on the conical surface of the grinding table after grinding. The shaken-off slurry falls through the gaps to the bottom of the processing bucket. After the ground slurry particles fall off the conical surface of the grinding table, the slurry particles added later will fall smoothly onto the conical surface of the grinding table for grinding. This avoids the ground slurry particles remaining on the grinding table, ensuring smooth discharge and facilitating continuous grinding of subsequent slurry. This effectively improves grinding efficiency and enhances practicality. Attached Figure Description

The outer wall of the feeding pipe 5 is fixedly fitted with a transmission gear ring 14, and the transmission gear ring 14 meshes with the transmission gear 13. Support plates 15 are symmetrically fixedly connected to the left and right sides of the bottom of the processing barrel 1. A transmission crankshaft 16 is rotatably mounted on the lower part of the two sets of support plates 15. The left end of the transmission crankshaft 16 passes through the support plate 15 and is aligned with the left output end of the motor 10. Synchronous pulleys 17 are fixedly connected to the left output end of the motor 10 and the left end of the transmission crankshaft 16. Transmission sleeves are mounted on the two sets of synchronous pulleys 17. Equipped with a synchronous belt 18, a transmission rod 19 is rotatably mounted in the middle of the transmission crankshaft 16, and a movable rod 8 is slidably mounted on the bottom of the grinding table 3 and the processing barrel 1.

The dislodged slurry then falls through the gaps to the bottom of the processing bucket 1. After the ground slurry particles have fallen from the conical surface of the grinding table 3, the subsequently added slurry particles will smoothly fall onto the conical surface of the grinding table 3 for further grinding. This prevents the ground slurry particles from remaining on the grinding table, ensuring smooth discharge and facilitating continuous grinding of subsequent slurry. This effectively improves grinding efficiency and enhances practicality.

[0020] Both sets of support plates 15 are fixedly connected to the bottom of the processing barrel 1 with reinforcing rods 27; by setting reinforcing rods 27, the connection between the support plates 15 and the processing barrel 1 can be made more firm and stable.

[0021] The present invention provides a slurry milling process for processing aluminum hydroxide flame retardants, which specifically includes the following steps: 1. Start-up: Start the above-mentioned slurry grinding device for processing aluminum hydroxide flame retardant; 2. Feeding: Add slurry particles to the feeding pipe 5 through the feeding hopper 25, so that the slurry particles fall onto the conical surface of the grinding table 3 through the feeding pipe 5 and the inlet. 3. Grinding: The slurry particles are ground by rotating the turntable 4 and grinding roller 7; 4. Discharge: The turntable 4 drives the scraper 21 to scrape the slurry falling to the bottom of the processing barrel 1, scraping the slurry to the discharge port 22, so that the slurry is discharged through the discharge port 22 and falls onto the receiving hopper 23, and is discharged by the guidance of the receiving hopper 23.

[0022] The working principle of the slurry grinding device for processing aluminum hydroxide flame retardant of the present invention is as follows: When grinding slurry particles, the motor 10 is started first. The motor 10 transmits the output power to the reducer 11, which drives the drive shaft 12 to rotate. The reducer 11 reduces the speed and increases the torque. In turn, the drive shaft 12 drives the feeding pipe 5 to rotate through the meshing of the transmission gear 13 and the transmission gear ring 14. The feeding pipe 5 drives the turntable 4 to rotate, which in turn drives multiple sets of grinding rollers 7 to rotate around the top conical surface of the grinding platform 3. Under the action of friction, the grinding rollers 7 rotate on their own. Then, slurry particles are added to the feeding pipe 5 through the feeding hopper 25. The slurry particles fall onto the conical surface of the grinding platform 3 through the feeding pipe 5 and the inlet. At this time, the unground slurry particles are too large to pass through the gap between the cylindrical surface of the conical groove and the outer circumference of the grinding platform 3. Therefore, they remain on the conical surface of the grinding platform 3. Through the rotation of the grinding rollers 7 and their rotation around the grinding platform, the slurry particles are ground. Three rotations are performed to continuously grind the slurry particles. Simultaneously, the motor 10 drives the transmission crankshaft 16 to rotate via the synchronous pulley 17 and synchronous belt 18. This causes the transmission crankshaft 16 to drive the movable rod 8 to slide up and down repeatedly via the transmission rod 19 and U-shaped connecting seat 20. This, in turn, causes the movable rod 8 to drive the striking head 9 to continuously strike the top of the cavity of the grinding table 3. The striking causes vibration on the outside of the grinding table 3. This vibration, in turn, causes the conical surface of the grinding table 3 to... After grinding, the remaining slurry particles are shaken off, allowing the slurry to fall through the gaps to the bottom of the processing tank 1. The rotation of the turntable 4 causes the scraper 21 to scrape the falling slurry, which is then scraped to the discharge port 22. The slurry is discharged through the discharge port 22 and falls onto the receiving hopper 23. The slurry is then discharged through the receiving hopper 23. The workers can place a box for collecting slurry under the receiving hopper 23 in advance to collect the slurry discharged from the receiving hopper 23.

[0023] The grinding device and grinding process for processing aluminum hydroxide flame retardant of the present invention are common mechanical methods in terms of installation, connection or setting. As long as they can achieve their beneficial effects, they can be implemented. The motor 10 and reducer 11 of the grinding device and grinding process for processing aluminum hydroxide flame retardant of the present invention are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual.

[0024] The above description is only a preferred embodiment of the present invention.
