Description

Technical Field

[0030] A number of slot holes are provided on the powder suction pipe 22.

[0031] The anti-blocking component further includes a group of second brush shafts 23;

[0032] A group of second brush shafts 23 are fixedly installed on the inner wall of the main pipeline 2. A group of second brush shafts 23 are respectively located on both sides of the filter screen cylinder 13. A group of second brush shafts 23 are all in contact with the outer wall of the filter screen cylinder 13.

[0033] The anti-blocking component further includes a secondary pipeline 3 and a first pump body 5;

[0034] Both ends of the secondary pipeline 3 are fixedly connected to one side of the main pipeline 2. The first pump body 5 is installed on the secondary pipeline 3.

[0035] The sealing component includes a first box 7, a second electric telescopic rod 12, and a second push plate 10;

[0036] The first box body 7 is fixedly installed on the main pipeline 2. The first box body 7 is located between the two ports of the auxiliary pipeline 3 where it is connected to the main pipeline 2. One end of the second electric telescopic rod 12 is fixedly connected to the upper wall inside the first box body 7, and the other end of the second electric telescopic rod 12 is fixedly connected above the second push plate 10. Both sides of the second push plate 10 are slidably connected to the inner wall of the first box body 7, and the lower part of the second push plate 10 slides through and penetrates the upper wall of the main pipeline 2.

[0037] The sealing assembly further includes a first electric telescopic rod 11 and a first push plate 9;

[0038] There is a ventilation opening above one end of the main pipeline 2 connected to the second box body 8.

[0039] Working principle: An air inlet is provided on one side of the grinding chamber 1. The second pump body 6 pumps the fine powder ground inside the grinding chamber 1 into the powder outlet pipe 4 through the main pipeline 2, and the fine powder is discharged through the powder outlet pipe 4. During this process, the fine powder passes through the filter mesh cylinder 13. The fine powder with smaller particles enters the inside of the filter mesh cylinder 13 through the mesh holes on the filter mesh cylinder 13 and enters the powder outlet pipe 4 through the slots on the powder suction pipe 22. The size of the mesh holes on the filter mesh cylinder 13 can be assembled according to the fineness of the required powder. The filter mesh cylinder 13 screens the fine powder with unqualified particle sizes outside the filter mesh cylinder 13. After the second pump body 6 stops operating, the large-particle powder loses suction and slides back into the grinding chamber 1 through the main pipeline 2 again, so that the grinding chamber 1 grinds it again. However, during the long-term operation of the second pump body 6, some fine powder adheres to the filter mesh cylinder 13, continuously blocking the filter mesh cylinder 13, reducing the gas and fine powder inhaled by the second pump body 6, and lowering the air pressure value inside the filter mesh cylinder 13. The air pressure sensor 19 installed on the first disc 14 sets the low-pressure value of the air pressure sensor 19 before installing it into the separator. The air pressure sensor 19 operates simultaneously with the second pump body 6. When the air pressure inside the filter mesh cylinder 13 is lower than the low-pressure value set by the air pressure sensor 19, the air pressure sensor 19 sends a signal to the signal processor, and the signal processor sends a signal to turn on a number of third electric telescopic rods 16, so that each group of third electric telescopic rods 16 pushes out the corresponding first brush shaft 17. At this time, the brush surfaces of the a number of pushed-out first brush shafts 17 contact the inner wall of the filter mesh cylinder 13. At the same time, the signal processor sends a signal to turn on the motor 18, the output end of the motor 18 drives the second gear 21 to rotate, the rotation of the second gear 21 drives the first gear 20 to rotate, and the rotation of the first gear 20 drives the second disc 15 to rotate. When the second disc 15 rotates, the second disc 15 drives the filter mesh cylinder 13 to rotate. The rotation of the filter mesh cylinder 13 causes the first brush shaft 17 in contact with the inner wall of the filter mesh cylinder 13 to sweep off the fine powder on the wall of the filter mesh cylinder 13. At this time, the still-operating second pump body 6 sucks the swept-off fine powder into the powder outlet pipe 4, achieving the effect of cleaning the filter mesh cylinder 13 and preventing the reduction of the working efficiency of the separator caused by the blockage of the filter mesh cylinder 13.

[0040] When the motor 18 drives the filter screen cylinder 13 to rotate, a group of second brush shafts 23 continuously brush the outer wall of the filter screen cylinder 13 as the filter screen cylinder 13 rotates, brushing off the fine powder adhering to the outer wall of the filter screen cylinder 13. The smaller fine powder particles outside the filter screen cylinder 13 are pumped into the powder outlet pipe 4 by the second pump body 6 again, while the larger fine powder particles are isolated outside the filter screen cylinder 13, reducing the effect of fine powder clogging the outer wall of the filter screen cylinder 13.

[0041] The signal processor is set with the specific time values for delaying the start of the first pump body 5, the second electric telescopic rod 12, and the first electric telescopic rod 11, and the specific time value for delaying the shutdown of the second pump body 6. When the air pressure sensor 19 sends a signal to the signal processor, after the signal processor sends a signal to turn on the motor 18 for a certain time value, it sends a signal to turn off the second pump body 6, and at the same time sends signals to turn on the second electric telescopic rod 12, the first electric telescopic rod 11, and the first pump body 5. The opened second electric telescopic rod 12 pushes the second push plate 10 downward, and the pushed second push plate 10 passes through the upper wall of the main pipe 2 downward, realizing the closing of the main pipe 2 and increasing the force for the first pump body 5 to pump the powdery particles at the filter screen cylinder 13 into the auxiliary pipe 3 during subsequent operation.

[0042] The opened first electric telescopic rod 11 pushes the first push plate 9 away from its original position. The first push plate 9 functions to seal the ventilation opening in its original position, preventing air leakage from the ventilation opening when the second pump body 6 is working, which may cause insufficient pumping force when the second pump body 6 pumps out the fine powder inside the grinding chamber 1. The opened first electric telescopic rod 11 pushes the first push plate 9 away from its original position, opening the ventilation opening to facilitate the inflow of gas when the first pump body 5 is working. The ventilation opening is arranged above the filter screen cylinder 13, and the inlet of the auxiliary pipe 3 is arranged below the filter screen cylinder 13. The ventilation opening and the inlet of the auxiliary pipe 3 form a diagonal position, enabling a large amount of the air flow pumped in through the ventilation opening by the first pump body 5 during operation to pass through the filter screen cylinder 13.

[0043] The first pump body 5 opened by the signal processor pumps the powdery particles around the filter screen cylinder 13 into the interior of the auxiliary pipe 3, and through the auxiliary pipe 3, the powdery particles are conveyed to the lower end of the main pipe 2 again and flow into the interior of the grinding chamber 1 for re-grinding. When the specific time for turning on the first pump body 5, the second electric telescopic rod 12, and the first electric telescopic rod 11, and the specific time for turning off the second pump body 6 are reached, the first pump body 5 stops operating, and the second electric telescopic rod 12 and the first electric telescopic rod 11 pull the second push plate 10 and the first push plate 9 back to their initial positions, and the second pump body 6 continues to work, cycling in this way until the required particle diameter is achieved.

[0044] Check valves are installed on both the first pump body 5 and the second pump body 6. The first pump body 5, the second pump body 6, the first electric telescopic rod 11, the second electric telescopic rod 12, the motor 18, the signal processor, the air pressure sensor 19, and the third electric telescopic rod 16 are all externally connected to a power source.
