Description

Technical Field

[0001] This utility model relates to the field of cyclone separator technology, and in particular to a cyclone separator with a secondary grading function. Background Technology

[0002] The cyclone separator with secondary grading function is an improvement on the traditional single-stage cyclone separator. It integrates the two-stage separation process into a single unit, typically consisting of a pre-separation main cyclone section at the top and a fine grading secondary separation section at the bottom. During operation, dust-laden gas enters the upper main body tangentially. Coarse particles are rapidly separated under strong centrifugal force and discharged into the dust collection hopper; while finer particles that are not completely captured enter the lower secondary separation section with the internal swirling flow, ultimately ensuring that most of the fine powder is effectively captured, greatly improving the overall separation efficiency. However, directly blowing in the airflow during secondary separation can disrupt the spiral airflow.

[0003] A search revealed a Chinese patent publication number CN219210294U, which discloses a cyclone classifier with a secondary particle classification function. The classifier includes an upper body, a cone connected to the lower end of the upper body, and a secondary air inlet connected to the lower end of the cone. The lower end of the secondary air inlet is connected to a collection bin. The secondary air inlet includes a spiral-shaped outer shell, the spiral of which is a planar spiral, and the spiral-shaped outer shell rotates once. Secondary air inlets are tangentially arranged at the inner and outer ends of the spiral of the spiral-shaped outer shell.

[0004] To address the problem in the aforementioned technologies that different secondary air supply velocities are required when separating different materials, and the guide vane angle cannot be changed accordingly to effectively match the inlet air velocity and reduce interference with the original spiral airflow, a cyclone separator with a secondary classification function is proposed.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-6 As shown, a cyclone separator with secondary grading function includes a cylinder 1. A makeup air zone 4 is fixedly connected to the lower part of the cylinder 1. A top outlet 2 and an air inlet pipe 5 are fixedly connected to the upper part of the cylinder 1. A discharge port 3 and a makeup air pipe 6 are fixedly connected to one side of the makeup air zone 4. Multiple bearings 19 are fixedly connected inside the makeup air zone 4. A rotating top plate 7 and a rotating base 9 are fixedly connected to the movable ends of the bearings 19 on the upper and lower sides, respectively. Multiple guide vanes 8 are rotatably connected to one end of the rotating top plate 7 and the rotating base 9. An adjusting gear 18 is fixedly connected to the lower end of the guide vanes 8. A synchronization component is driven to the other end of the adjusting gear 18. A worm gear 22 is fixedly connected to one end of the synchronization component. A worm 23 is driven to the other end of the worm gear 22. An adjusting motor 24 is fixedly connected to the inner side of the rotating base 9. The worm 23 is fixedly connected to the power output end of the adjusting motor 24.

[0031] During use, the airflow carrying powder enters through the air inlet pipe 5. After the first separation inside the cylinder 1, the large powder particles fall into the make-up air zone 4. At this time, the secondary make-up air enters through the air inlet pipe 5, which is connected to an external fan. The make-up air speed can be intelligently monitored and adjusted. When the secondary make-up airflow comes into contact with the spiral airflow carrying large powder particles, it can accelerate the airflow, allowing these powder particles to be separated again and discharged upward from the top outlet 2, thus improving the screening efficiency. The rotating top plate 7 and the rotating base 9 are also installed.

[0032] The synchronization assembly includes a synchronization gear ring 17, an adjusting gear ring 20, and a drive gear 21. The synchronization gear ring 17 is rotatably connected to the inner wall of the rotating base 9. Multiple adjusting gears 18 mesh with the inner side of the synchronization gear ring 17. The adjusting gear ring 20 is fixedly connected below the synchronization gear ring 17, and the other end of the adjusting gear ring 20 meshes with the drive gear 21. One side of the drive gear 21 is fixedly connected to one end of the worm gear 22. The drive gear 21 and the worm gear 22 are rotatably connected to the inner wall of the rotating base 9.

[0033] When the wind enters the make-up air zone 4, the guide vanes 8 guide the airflow coming from the side to be stably mixed into the spiral airflow, avoiding the airflow from running around and disturbing the spiral airflow and affecting the final separation result. Precise control of the airflow direction can reduce unnecessary energy waste.

[0034] After the wind speed of the secondary air supply is adjusted, the angle of the guide vanes 8 needs to be adjusted synchronously. At this time, the motor 24 can be adjusted to drive the worm gear 23 to rotate, which in turn drives the synchronous gear ring 17 to rotate through the worm wheel 22. This can drive the multiple guide vanes 8 rotating in the rotating top plate 7 and the rotating base 9 to rotate at an angle to match the wind speed of the secondary air supply, so that the secondary air supply can accelerate the spiral airflow and separate it better without disturbing the original spiral airflow.

[0035] Furthermore, the worm gear transmission has self-locking properties, which can prevent the synchronous gear ring 17 and the guide vane 8 from shaking when the rotating base 9 rotates at high speed.

[0036] In this embodiment, a control module 25 is fixedly connected to the inner wall of the rotating base 9. One side of the control module 25 is electrically connected to the regulating motor 24. The rotating base 9 and the air supply area 4 are respectively provided with maintenance slots 12. One end of the maintenance slot 12 is fixedly connected to a maintenance guard plate 13 by bolts.

[0037] The control module 25 is a module that integrates a wireless communication module, a battery compartment and a control circuit board. It can receive external signals to control the forward and reverse rotation of the adjustment motor 24. The adjustment motor 24 is preferably a servo motor, which can adjust the angle more accurately.

[0038] When maintenance is required, the inspection plate 13 under the rotating base 9 and the air supply area 4 can be opened for maintenance and battery replacement. The inside of the inspection plate 13 has a sealing strip to prevent air leakage.

[0039] In this embodiment: During use, the airflow carrying powder enters through the air inlet pipe 5. After the first separation inside the cylinder 1, the large powder particles fall into the make-up air zone 4. At this time, the secondary make-up air enters through the air inlet pipe 5, which is connected to an external fan. The make-up air speed can be intelligently monitored and adjusted. When the secondary make-up airflow comes into contact with the spiral airflow carrying large powder particles, the airflow can be accelerated, allowing these powder particles to be separated again into fine powder particles that are discharged upwards from the top outlet 2, thereby improving the screening efficiency. The rotating top plate 7 and the rotating base 9 are also installed.

[0040] When the wind enters the make-up air zone 4, the guide vanes 8 guide the airflow coming from the side to be stably mixed into the spiral airflow, avoiding the airflow from running around and disturbing the spiral airflow and affecting the final separation result. Precise control of the airflow direction can reduce unnecessary energy waste.

[0041] After the wind speed of the secondary air supply is adjusted, the angle of the guide vanes 8 needs to be adjusted synchronously. At this time, the motor 24 can be adjusted to drive the worm gear 23 to rotate, which in turn drives the synchronous gear ring 17 to rotate through the worm wheel 22. This can drive the multiple guide vanes 8 rotating in the rotating top plate 7 and the rotating base 9 to rotate at an angle to match the wind speed of the secondary air supply, so that the secondary air supply can accelerate the spiral airflow and separate it better without disturbing the original spiral airflow.

[0042] Furthermore, the worm gear transmission has self-locking properties, which can prevent the synchronous gear ring 17 and the guide vane 8 from shaking when the rotating base 9 rotates at high speed;

[0043] The control module 25 is a module that integrates a wireless communication module, a battery compartment and a control circuit board. It can receive external signals to control the forward and reverse rotation of the adjustment motor 24. The adjustment motor 24 is preferably a servo motor, which can adjust the angle more accurately.

[0044] When maintenance is required, the inspection plate 13 under the rotating base 9 and the air supply area 4 can be opened for maintenance and battery replacement. The inside of the inspection plate 13 has a sealing strip to prevent air leakage.

[0045] Example 2:

[0046] A cyclone separator with secondary grading function is described in this embodiment, which is an improvement on embodiment 1, as follows: Figure 1-6 As shown,

[0047] In this embodiment, a protective cover plate 10 is fixedly connected to one side of the air supply area 4, a positioning push rod 11 is fixedly connected to the inner side of the protective cover plate 10, a positioning plate 14 is slidably connected to the upper movable end of the positioning push rod 11, a spring 15 is fixedly connected to the rear side of the positioning plate 14 and the upper movable end of the positioning push rod 11, and a positioning hole 26 is opened at the bottom of the rotating base 9.

[0048] The bottom of the air supply area 4 has an opening. When it is necessary to stop the machine for maintenance, first wait for the rotation speed of the rotating base 9 to decrease. Then, the positioning push rod 11 extends and rises through the positioning plate 14 at its movable end to fit tightly against the bottom of the rotating base 9. Then, when the positioning hole 26 is aligned with the positioning plate 14, the positioning plate 14 is inserted into the positioning hole 26 under the action of the spring 15 to position the rotating base 9, so that the rotating base 9 and the maintenance groove 12 below the air supply area 4 are aligned for maintenance.

[0049] When the positioning push rod 11 retracts, the upper end of the top positioning plate 14 is flush with the bottom inner wall of the air supply area 4 to prevent airflow disturbance, and the protective cover plate 10 can prevent air leakage.

[0050] In this embodiment, a counterweight 16 is fixedly connected to the other side of the rotating base 9. The counterweight 16 is symmetrically installed with the adjusting motor 24 and the control module 25 to make the rotation of the rotating base 9 more balanced.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
