Description

Technical Field

[0001] This application relates to the field of dust collector technology, and more specifically, to an adjustable air inlet structure for a dust collector. Background Technology

[0002] Cyclone dust collectors are a type of dust removal device. Their dust removal mechanism involves rotating the dust-laden airflow, using centrifugal force to separate dust particles from the airflow and collect them on the collector wall. Gravity then causes the dust particles to fall into the ash hopper. Each component of a cyclone dust collector has specific dimensional proportions, and changes in any of these proportions can affect the efficiency and pressure loss of the cyclone dust collector. The diameter of the dust collector, the size of the inlet, and the diameter of the exhaust pipe are the main influencing factors. During use, it should be noted that when certain limits are exceeded, even beneficial factors can turn into detrimental ones. In addition, some factors that are beneficial to improving dust removal efficiency may increase pressure loss. Therefore, adjustments to all factors must be made in a balanced manner.

[0003] Existing cyclone dust collectors have fixed air inlets, making it impossible to adjust them according to different operating conditions and dust characteristics. This significantly impacts dust removal efficiency when handling different types of dust or when facing changing operating conditions, failing to meet the demands of actual production for high-efficiency dust removal.

[0004] To address the aforementioned issues, this application provides an adjustable air inlet structure for a dust collector. Utility Model Content

[0005] The adjustable air inlet structure of the dust collector provided in this application adopts the following technical solution:

[0006] The dust collector has an adjustable air inlet structure, including a cyclone dust collector and an air inlet. The air inlet is connected to the air inlet end of the cyclone dust collector, and an electric actuator is fixedly installed on the outer wall of the air inlet by a mounting bracket. The electric actuator is connected to a first rotating shaft via a coupling. The first rotating shaft extends into the air inlet, and a first door plate is fixedly installed on the surface of the first rotating shaft. A second rotating shaft is rotatably connected to the air inlet on one side of the first door plate, and a second door plate is fixedly installed on the surface of the second rotating shaft. The other end of the second door plate is rotatably connected to a connecting rod via a rotating pin. The other end of the connecting rod is also rotatably connected to the other end of the first door plate via a rotating pin.

[0007] The above technical solution uses an electric actuator to drive the first rotating shaft to rotate, which in turn drives the first door panel to rotate. The rotating pin at the other end of the door panel drives the connecting rod and the second door panel to rotate, changing the angle between the first and second door panels and thus changing the air intake angle. By using different airflow directions, the opening and closing size of the first and second door panels can be controlled by rotating the first rotating shaft, thereby adjusting the size of the air intake, accurately controlling the air intake volume, and improving work efficiency.

[0008] Furthermore, the first door panel and the second door panel have the same structure, and the dimensions of the first door panel and the second door panel are adapted to the internal dimensions of the air intake.

[0009] With the above technical solution, the dimensions of the first door panel and the second door panel are arranged according to the size of the air inlet, and the size of the air inlet is set according to the size of the air inlet end of the cyclone dust collector.

[0010] Furthermore, an air volume detector is installed upstream of the air inlet, and the air volume detector is electrically connected to the electric actuator via a controller.

[0011] Through the above technical solution, the air volume detector detects the air volume in the pipeline and sends a signal back. The controller controls the electric actuator to adjust the rotation of the first rotating shaft, thereby automatically adjusting the opening and closing size of the first and second door panels and accurately controlling the air intake.

[0012] Furthermore, both the first and second rotating shafts are rotatably connected to the air inlet surface via sealed bearings.

[0013] Through the above technical solution, the sealed bearing plays a role in stabilizing rotation and preventing gas leakage.

[0014] Furthermore, one end of the first rotating shaft is fixedly connected to the output end of the coupling, and the input end of the coupling is fixedly connected to the output end of the electric actuator.

[0015] Through the above technical solution, the coupling facilitates the connection between the electric actuator and the first rotating shaft, which is a common type of drive connection.

[0016] Furthermore, one end of the air inlet is sealed to the air inlet end of the cyclone dust collector.

[0017] The above technical solution avoids air leakage.

[0018] Furthermore, both the first and second door panels are polished.

[0019] The above technical solutions prevent powder residue from adhering.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] The electric actuator drives the first rotating shaft to rotate, which in turn drives the first door panel to rotate. The rotating pin at the other end of the door panel drives the connecting rod and the second door panel to rotate, changing the angle between the first and second door panels, thereby changing the air intake angle. By using different airflow directions, the opening and closing size of the first and second door panels is controlled by rotating the first rotating shaft, thereby adjusting the size of the air intake, precisely controlling the air intake volume, and improving work efficiency.

The pivot pin 11 is rotatably connected to the connecting rod 10. The other end of the connecting rod 10 is also rotatably connected to the other end of the first door panel 7 via the pivot pin 11. The electric actuator 4 drives the first rotating shaft 6 to rotate, which in turn drives the first door panel 7 to rotate. Then, the pivot pin 11 at the other end of the door panel drives the connecting rod 10 and the second door panel 9 to rotate, changing the angle of the first door panel 7 and the second door panel 9, thereby changing the air intake angle. By using different airflow directions, the opening and closing size of the first door panel 7 and the second door panel 9 is controlled by rotating the first rotating shaft, thereby adjusting the size of the air intake 2, accurately controlling the air intake volume, and improving work efficiency.

[0035] Please see Figure 5 and Figure 6 The first door panel 7 and the second door panel 9 have the same structure, and the dimensions of the first door panel 7 and the second door panel 9 are adapted to the internal dimensions of the air inlet 2.

The controller controls the electric actuator 4 to adjust the rotation of the first rotating shaft 6, thereby automatically adjusting the opening and closing size of the first door panel 7 and the second door panel 9 to precisely control the air intake.

[0037] Please see Figure 4 The first rotating shaft 6 and the second rotating shaft 8 are both rotatably connected to the surface of the air inlet 2 through sealed bearings. The sealed bearings play a role in stabilizing the rotation and preventing gas leakage.

[0041] The implementation principle of this embodiment is as follows: In use, the electric actuator 4 drives the first rotating shaft 6 to rotate, which in turn drives the first door panel 7 to rotate. Then, the rotating pin 11 at the other end of the door panel drives the connecting rod 10 and the second door panel 9 to rotate, changing the angle of the first door panel 7 and the second door panel 9, thereby changing the air intake angle. By using different airflow directions, the opening and closing size of the first door panel 7 and the second door panel 9 is controlled by rotating the first rotating shaft, thereby adjusting the size of the air intake 2, accurately controlling the air intake volume, and improving work efficiency.
