Description

Technical Field

[0001] The utility model belongs to the technical field of dust collection equipment, and particularly relates to a cyclone dust collection equipment for impact mills. Background Technique

[0002] Cyclone dust collection equipment is an efficient dust collection system, which is widely used in industrial production to solve the problem of dust pollution. Its working principle is based on the principle of centrifugal force. When the gas containing dust enters the interior of the equipment, high-speed rotation generates centrifugal force, causing the larger particulate matter in the gas to be thrown towards the inner wall of the equipment and settle, thus achieving separation from the gas. This equipment has a simple structure, does not require a complex control system during operation, and has a low maintenance cost. Therefore, it has a high cost performance in industrial applications. With the progress of technology, continuous improvements have been made in aspects such as material selection, structural optimization, and automatic control of cyclone dust collection equipment, further improving its dust removal efficiency and adaptability, enabling it to meet the requirements of different industrial environments and dust characteristics.

[0003] Chinese Utility Model CN212914834U discloses a cyclone dust collection device, which includes a cyclone dust collector and a centrifugal fan. The centrifugal fan includes a first exhaust duct, a second exhaust duct, and a third exhaust duct. The first exhaust duct and the third exhaust duct are connected to the side of the centrifugal fan, the second exhaust duct is connected to the bottom of the centrifugal fan, and the second exhaust duct is located inside the cyclone dust collector. The airflow containing dust rises from the middle after separating most of the dust in the cyclone dust collector and enters the centrifugal fan. Under the action of the centrifugal fan, a part enters the first exhaust duct and then enters the backend dust removal equipment for recovery, a part of the lower airflow with a higher dust content enters the second exhaust duct and re-enters the cyclone dust collector through the air path at the lower end for secondary dust collection, and another part enters the third exhaust duct and then enters the front-end system for recycling, reducing the load on the backend dust removal equipment and reducing the dust content in the discharged air.

[0004] However, a part enters the first exhaust duct and then enters the backend dust removal equipment for recovery, a part of the lower airflow with a higher dust content enters the second exhaust duct and re-enters the cyclone dust collector through the air path at the lower end for secondary dust collection, and another part enters the third exhaust duct and then enters the front-end system for recycling. This equipment does not perform fine sorting and recovery of dust, and for those who need to classify dust, it cannot achieve the effect of fine sorting and recovery. Content of the Utility Model

[0071] Embodiment 2:

[0072] From Figure 3 - Figure 4 As shown, this embodiment provides a cyclone dust collector for an impact mill. In addition to including the technical solutions of the above embodiment, it also has the following technical features. A guiding structure is symmetrically arranged in the centrifugal cylinder 2. The guiding structure includes: a second motor 14, which is arranged at the top of the centrifugal cylinder 2, and a guiding rod 15 is arranged through the end face of the output shaft of the second motor 14 at the top of the centrifugal cylinder 2. There are two guiding rods 15; a guiding plate 16, which is circumferentially arranged on the guiding rod 15.

[0073] The rotation speed of the second motor 14 is less than that of the first motor 4. The second motor 14 drives the guiding rod 15 to rotate. The guiding plate 16 cooperates with the guiding rod 15 to guide the dust remaining in the sorting chamber 8 again, so that the dust is sorted repeatedly, which is beneficial to improving the utilization rate of the dust. A vibration motor 17 is arranged in the middle of the top of the centrifugal cylinder 2, and a vibration damping structure is arranged at the bottom of the support frame 1.

[0074] The vibration motor 17 vibrates to shake off the dust adhering to the inner wall, and the diversion structure diverts the dust, which is beneficial to improving the utilization rate of the dust. The vibration damping structure includes: a vibration damping frame 18, the vibration damping frame 18 is arranged below the first discharge pipe 10; an outer cylinder 25, the outer cylinder 25 is connected and arranged at the bottom of the vibration damping frame 18, and a piston rod 30 is sleeved in the outer cylinder 25; an oil needle rod 29, the oil needle rod 29 is sleeved inside the piston, and oil limiting valves 24 are symmetrically arranged on both sides of the upper end of the oil needle rod 29; oil return holes 26, the oil return holes 26 are symmetrically arranged on both sides of the oil limiting valves 24, and an oil return cavity 28 is arranged below the oil return holes 26, the oil return cavity 28 is arranged between the piston rod 30 and the outer cylinder 25; a floating piston 23, the floating pistons 23 are symmetrically arranged above the oil return holes 26, and a first low-pressure cavity 22 is arranged between the floating piston 23 and the oil return holes 26; a low-pressure filling nozzle 20, the low-pressure filling nozzle 20 is arranged on the left side of the top of the outer cylinder 25, and a second low-pressure cavity 33 is arranged between the low-pressure filling nozzle 20 and the oil needle rod 29; a third low-pressure cavity 34, the third low-pressure cavity 34 is arranged between the piston rod 30 and the oil needle rod 29; a high-pressure filling nozzle 19, the high-pressure filling nozzle 19 is arranged on the right side of the top of the outer cylinder 25, and a first high-pressure cavity 21 is arranged between the high-pressure filling nozzle 19 and the floating piston 23, and a second high-pressure cavity 35 is arranged below the anti-braking valve 27; wherein, the floating piston 23 is slidably connected with the outer cylinder 25, and the oil needle rod 29 is slidably connected with the piston rod 30.

[0075] After the vibration motor 17 vibrates, the device starts to vibrate, and the vibration causes the piston to move. During the up and down pushing of the piston, the volumes of the first low-pressure cavity 22 and the third low-pressure cavity 34 become smaller, and the oil in the third low-pressure cavity 34 will enter the second low-pressure cavity 33 through the relevant device system. A part of the oil in the first low-pressure cavity 22 will enter the second high-pressure cavity 35 through the relevant device, and the other part will flow into the second low-pressure cavity 33 through the relevant device.

Due to the generation of pressure energy, the vibration force will be reduced. Moreover, a series of frictional forces are generated during the flow of the oil, and these frictional forces will reduce the generation of some forces.

[0076] Working principle: Dust enters the centrifugal cylinder 2 from the feed inlet. The first motor 4 drives the centrifugal fan 5 to rotate. The centrifugal fan 5 generates centrifugal force. Coarse-particle dust cannot pass through the filter column 6 and falls to the bottom of the conical cylinder 3. The holes 7 are designed to be 2 - 74 μm to prevent coarse-particle dust from entering the filter column 6. Due to the centrifugal effect, the coarse-particle dust falls to the bottom of the sorting chamber 8. Since the bottom of the sorting chamber 8 is V-shaped, the coarse-particle dust slides into the channel 32 and enters the first dust storage chamber 9, and is conveyed out through the first discharge pipe 10. Fine-particle dust enters the filter column 6 through the holes 7. Since the connecting cylinder 13 is V-shaped, the fine-particle dust slides from the connecting cylinder 13 into the second dust storage chamber 11. The second discharge pipe 12 is arranged at the lowest point of the second dust storage chamber 11, so that the fine-particle dust slides from the second dust storage chamber 11 to the second discharge pipe 12 and is finally conveyed out. The vibration motor 17 vibrates to shake off the dust adhering to the inner wall. The rotation speed of the second motor 14 is less than that of the first motor 4. The second motor 14 drives the guide rod 15 to rotate. The guide plate 16 cooperates with the guide rod 15 to re-guide the dust remaining in the sorting chamber 8, so that the dust is sorted repeatedly. After the vibration motor 17 vibrates, the shock-absorbing structure unloads the transmitted vibration.
