Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The present invention provides Figures 1 to 6 The shown device is a multi-stage screening porcelain insulator powder preparation and screening device, comprising a support frame 1, a crushing box 2 fixed to the top of the support frame 1, the bottom end of the crushing box 2 is connected to the conveying box 5, and support legs are fixed to the four corners of the bottom end of the support frame 1, and anti-slip pads are fixed to the bottom ends of the four support legs. The support frame 1 can support and fix the crushing box 2 and the conveying box 5, and the anti-slip pads can prevent the entire device from moving due to vibration after startup, causing tipping.

[0032] Two first motors 6 are disposed outside the crushing box 2. A rotating shaft 7 is connected to one side of each first motor 6. Both rotating shafts 7 extend into the crushing box 2. First crushing teeth 3 and second crushing teeth 4 are fixed to the outer sides of the extending ends of the two rotating shafts 7. The first crushing teeth 3 and second crushing teeth 4 interlock and mesh with each other. The crushing box 2 has an opening for powder to enter.

[0033] In the actual operation of the present invention, the powder to be screened can be poured into the interior of the crushing box 2 from the opening. The two first motors 6 are started, which can respectively drive the first crushing teeth 3 and the second crushing teeth 4 to rotate relative to each other, and the first crushing teeth 3 and the second crushing teeth 4 are staggered and engaged with each other to crush the falling powder, reduce large particles and lumps in the powder, and make screening more convenient.

[0034] A rotating shaft 13 is connected to the inside of the conveying box 5 in a rotatable manner along the length direction, and a spiral blade 14 is fixed to the outside of the rotating shaft 13. The conveying box 5 is fixed to the inside of the support frame 1, and a second motor 20 is fixed to one side of the conveying box 5. One end of the rotating shaft 13 is fixedly connected to the drive shaft of the second motor 20, and the other end of the rotating shaft 13 extends out of the conveying box 5. A vertical plate 16 is fixed on the support frame 1, and the protruding end of the other end of the rotating shaft 13 is rotatably connected to the vertical plate 16. The crushed powder will fall into the interior of the conveying box 5.

[0035] By starting the second motor 20 , the rotating shaft 13 can be rotated, so that the spiral blade 14 can be rotated, thereby driving the falling crushed powder to move and move along the direction of the conveying box 5 .

[0036] In order to solve the problem that ceramic powder of existing porcelain insulators is easily adhered to the filter screen during the screening process, which may reduce the screening efficiency of ceramic powder and reduce the practicality of the device when in use, a first discharge area 10 and a second discharge area 11 are distributed at the bottom end of the conveying box 5. The first discharge area 10 and the second discharge area 11 are distributed along the length direction of the bottom end of the conveying box 5, and a plurality of leakage holes 12 are opened on the first discharge area 10 and the second discharge area 11 along the length direction. The radius of the leakage hole 12 of the first discharge area 10 is smaller than the radius of the leakage hole 12 of the second discharge area 11. A long plate 18 is fixed to the outside of the spiral blade 14, and a plurality of silicone soft columns 17 are fixed on the side of the long plate 18 away from the spiral blade 14. The tips of the plurality of silicone soft columns 17 correspond to the positions of the leakage holes 12, and a discharge port 21 is opened on the side of the conveying box 5 away from the second motor 20.

[0037] It should be noted that, as needed, a third discharge area, a fourth discharge area and other areas may be opened at the bottom of the conveying box 5 to increase the number of classifications.

[0038] In the actual operation of the present invention, when the spiral blade 14 drives the crushed powder to move, it will drive the powder to pass through the first discharge area 10 and the second discharge area 11 in sequence. The powder size from small to large passes through the leakage holes 12 on the first discharge area 10 and the second discharge area 11 respectively, completing multi-stage screening. The powder that does not meet the requirements of the first discharge area 10 and the second discharge area 11 will continue to move and be discharged from the discharge port 21, completing the screening and discharge of substandard particles at the same time.

[0039] The spiral blades 14 are distributed along the length direction of the rotating shaft 13, the conveying box 5 is set to a triangular prism shape with the tip of the triangular prism facing downward, the long plate 18 is distributed along the length direction of the spiral blade 14, and multiple silicone soft columns 17 are distributed at equal distances along the length direction of the long plate 18.

[0040] At the same time, the spiral blade 14 will rotate when conveying powder, and while rotating, it will drive the long plate 18 and the silicone soft column 17 to intermittently correspond to the position of the leakage hole 12. When the silicone soft column 17 rotates to the position corresponding to the leakage hole 12, the tip of the silicone soft column 17 will be inserted into the leakage hole 12 to push out the powder remaining inside the leakage hole 12, thereby reducing the blockage of the leakage hole 12 and incomplete discharge of powder.

[0041] Moreover, the powder is kept in a closed environment during the process from crushing to screening, and will not adhere to fixed dust and impurities in the air, thus improving the purity of the powder.

[0042] A plurality of needles 15 are fixed to the outside of the rotating shaft 13 . The plurality of needles 15 are distributed at equal distances along the length of the rotating shaft 13 , and the length of the needles 15 is shorter than the radius of the spiral blade 14 .

[0043] When the rotating shaft 13 rotates, the plurality of needles 15 penetrate into the powder, thereby reducing the air inside and breaking up the remaining lumps.

[0044] An air hole 19 is provided on the outside of the conveying box 5, and the air hole 19 is connected to the inside of the conveying box 5. The air hole 19 can be connected to a fan so that wind can enter the inside of the conveying box 5, speeding up the discharge and screening speed of the powder and reducing the adhesion of the powder to the inner wall of the conveying box 5.

[0045] The crushing box 2 is located above the first discharge area 10 of the conveying box 5 .

[0046] A collecting box 8 is fixed at the bottom end of the support frame 1, and an isolation plate 9 is fixed in the middle of the collecting box 8. The isolation plate 9 divides the inside of the collecting box 8 into two collecting areas. The first discharge area 10 and the second discharge area 11 correspond vertically to the two collecting areas respectively.

[0047] The powder materials screened and discharged from the first discharge area 10 and the second discharge area 11 can enter the two collecting areas of the collecting box 8 respectively, and are automatically classified and collected, thereby improving production efficiency.

[0048] Working principle: In the actual operation of the present invention, the powder to be screened can be poured into the interior of the crushing box 2 from the opening. The two first motors 6 are started, which can respectively drive the first crushing teeth 3 and the second crushing teeth 4 to rotate relative to each other, and the first crushing teeth 3 and the second crushing teeth 4 are staggered and engaged with each other to crush the falling powder, reduce large particles and lumps in the powder, and make screening more convenient.

[0049] By starting the second motor 20 , the rotating shaft 13 can be rotated, so that the spiral blade 14 can be rotated, thereby driving the falling crushed powder to move and move along the direction of the conveying box 5 .

[0050] When the spiral blade 14 drives the crushed powder to move, it will drive the powder to pass through the first discharge area 10 and the second discharge area 11 in sequence. The powder size from small to large passes through the leakage holes 12 on the first discharge area 10 and the second discharge area 11 respectively, completing multi-stage screening. The powder that does not meet the requirements of the first discharge area 10 and the second discharge area 11 will continue to move and be discharged from the discharge port 21, completing the screening and discharge of substandard particles at the same time.

[0051] At the same time, the spiral blade 14 will rotate when conveying powder, and while rotating, it will drive the long plate 18 and the silicone soft column 17 to intermittently correspond to the position of the leakage hole 12. When the silicone soft column 17 rotates to the position corresponding to the leakage hole 12, the tip of the silicone soft column 17 will be inserted into the leakage hole 12, and the powder remaining inside the leakage hole 12 will be pushed out, reducing the blockage of the leakage hole 12 and incomplete discharge of powder. The powder screened and discharged from the first discharge area 10 and the second discharge area 11 can enter the two collection areas of the collection box 8 respectively, automatically completing classification and collection, and improving production efficiency.
