Secondly, the first channel 142, the second channel 144 and the third channel 146 arranged on the second chamber 140 enable the first chamber 130, the second chamber 140, the interior of the spherical shell 120, the interior of the shell 110 and other spaces to be communicated, and the gas with dust can be conveniently separated from the dust under the action of centrifugal force.

Thirdly, the first chamber 130, the second chamber 140 and the spherical shell 120 are sequentially connected through the first channel 142 and the second channel 144 arranged on the second chamber 140, and when the spherical shell 120 rotates along the rotation axis, the first chamber 130 and the second chamber 140 rotate synchronously along with the spherical shell 120, so as to achieve the purpose of centrifugal dust removal.

In the centrifugal dust collector 100 provided by the embodiment of the invention, under the action that the air exhaust port is connected with the air extractor, negative pressure is formed in the equipment. Through the air inlet channel 112 arranged at the top end of the shell 110 and the spherical shell 120 arranged in the shell 110 and communicated with the air inlet channel 112, the gas with dust is discharged into the spherical shell 120, the spherical shell 120 rotates to drive the gas to rotate to generate centrifugal force, and part of dust is separated from the dust-containing gas and is settled along the inner wall of the spherical shell 120 under the action of the centrifugal force and is discharged along the second dust channel 122. The separated gas enters the second chamber 140 through the third passage 146, the gas with dust is again subjected to rotational centrifugal separation in the second chamber 140, and simultaneously, due to the centrifugal force generated by the rotation of the spherical shell 120, the dust particles separated from the dust-containing gas enter the housing 110 from the second passage 144 of the second chamber 140 and are finally discharged from the first dust passage 114. The separated gas in the second chamber 140 can enter the first chamber 130 through the first passage 142, and rotate again in the first chamber 130, so that the dust is further separated by centrifugal force and settles along the inner wall of the first chamber 130, the separated gas is discharged from the exhaust passage 132, and the dust is discharged from the third dust passage 134. Through the organic combination of the first chamber 130, the second chamber 140, the spherical shell 120 and the shell 110, under the action of a multiple centrifugal force field, multi-stage separation can be achieved, and meanwhile, the dust back-mixing probability is reduced, and further, the separation efficiency is improved.

As shown in fig. 1, the outer casing 110 includes a cylindrical casing 116 and a truncated cone shaped casing 118 connected to one end of the cylindrical casing 116, a lower bottom of the truncated cone shaped casing 118 is connected to the cylindrical casing 116, the air intake passage 112 is provided on an end surface of the cylindrical casing 116 remote from the truncated cone shaped casing 118, and the first dust passage 114 is provided on an upper bottom of the truncated cone shaped casing 118. Therefore, the required space for the rotation of the spherical shell 120 can be effectively ensured, and the gas with dust can smoothly slide down along the inner wall of the shell 110 under the centrifugal action, so that the dust can be discharged in time.

as shown in fig. 1 and fig. 2, the centrifugal dust collector 100 further includes a frame (not shown), the air inlet channel 112 is provided with a first bearing 1122, the first bearing 1122 is connected to the frame through a bearing seat, the outer wall of the second dust channel 122 is provided with a second bearing 1222, the inner wall of the circular truncated cone-shaped housing 118 is provided with a holder 1182, and the second dust channel 122 is rotatably connected to the holder 1182 through the second bearing 1222.

By adopting the above structure, when the spherical shell 120 rotates, the first bearing 1122 and the second bearing 1222 can rotate, so that the rotation of the spherical shell 120 is more stable, the rotation friction force is reduced, the abrasion of the rotation part of the air inlet channel 112 and the second dust channel 122 on the spherical shell 120 is reduced, and the service life is prolonged.

Optionally, as shown in FIG. 1, the centrifugal dust collector 100 further comprises an electric motor (not shown in FIG. 1) which is in belt-driven connection with the air inlet passage 112.

Thus, the centrifugal dust collector 100 can work continuously and stably, the transmission between the first bearing 1122 and the motor is more stable, and the start and stop of the centrifugal dust collector 100 can be controlled conveniently through the motor.

As shown in fig. 2, the first chamber 130 and the second chamber 140 are both rotating bodies, and a second preset included angle is formed between the central axis of the first chamber 130 and the central axis of the second chamber 140.

Specifically, the second preset included angle between the central axis of the first chamber 130 and the central axis of the second chamber 140 may be set to 20 °, 25 °, 30 °, and the like, so that the mutual structure may be more compact, and it is also beneficial to provide a required centrifugal force to separate dust efficiently. Meanwhile, the gas is discharged through the first chamber 130, the dust-laden gas is promoted to be separated into dust, and the separated gas is discharged continuously.

Optionally, a sealing bearing is further disposed on the air inlet passage 112, and the air inlet passage 112 and the housing 110 are connected through the sealing bearing.

thus, not only the air inlet passage 112 and the housing 110 are sealed, but also the dust-laden gas is prevented from leaking out from the gap between the air inlet passage 112 and the housing 110, and the sealing performance of the centrifugal dust collector 100 is prevented from being affected. The air inlet passage 112 and the outer shell 110 can be connected in a smooth rotating mode, rotation of the spherical shell 120 connected with the air inlet passage 112 is facilitated, and stability in use is improved.

As shown in fig. 2, the shape of the radial section of the third passage 146 includes any one of a circle and a polygon. For example, the third channel 146 may be configured as a circle, a boss, a regular hexagon, or the like, and may be flexibly configured according to the gas flow rate of the actual requirement, so that the gas flow is more stable, and the dust separation effect is better.

Alternatively, the shape of the spherical shell 120 includes any one of an ellipsoid and a sphere. When the spherical shell 120 is in the shape of an ellipsoid, the main axis of the ellipsoid is consistent with the axes of the air inlet channel 112 and the second dust channel 122 on the spherical shell 120, so that the spherical shell 120 is stressed in a balanced manner when rotating, and the stability of dust separation is improved.

Optionally, as shown in fig. 2, the centrifugal dust collector 100 further includes a dust collecting device (not shown in fig. 2), the dust collecting device is disposed at the first dust channel 114, and the aperture of the access port of the dust collecting device is greater than or equal to the aperture of the first dust channel 114.

For example, the dust collecting device may use a water seal to make the first dust channel 114, the second dust channel 122, and the third dust channel 134 reach deep below the liquid surface of the dust collecting device. The collection of the dust bag can also be achieved by connecting the first dust channel 114, the second dust channel 122 and the third dust channel 134 with the inlet of the bag.

The working principle of the centrifugal dust collector 100 is as follows: the dust-laden gas enters the interior of the spherical housing 120 from the gas inlet passage 112, and due to the rotation of the spherical housing 120, the dust-laden gas entering the spherical housing 120 is rotated by the rotation of the spherical housing 120, and a part of dust particles collide with the spherical housing 120 to be settled and are discharged from the second dust passage 122. In addition, the gas enters the second chamber 140 from the third passage 146 of the second chamber 140 and is rotated and centrifuged in the second chamber 140, and the dust particles enter the housing 110 from the second passage 144 of the second chamber 140 and are finally discharged from the first dust passage 114. The gas in the second chamber 140 is discharged from the first passage 142 into the first chamber 130, the rotation separation occurs in the first chamber 130, the separated dust particles are discharged from the third dust passage 134, and the separated gas is discharged from the exhaust passage 132.

The dust removal system incorporates the same structure and benefits as the centrifugal dust remover 100 in the previous embodiment. The structure and advantages of the centrifugal dust collector 100 have been described in detail in the foregoing embodiments, and will not be described in detail herein.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
