Problems solved by technology

However, the inventor found that although the existing two-stage cyclone separation can effectively improve the separation effect of dust and air, the cyclone separation cylinder of the downstream cyclone separation assembly accumulates a large amount of dust, and there is also dust accumulation outside the overflow cylinder, mainly due to the separation The final dust is difficult to be discharged to the dust outlet only by its own gravity, resulting in a large amount of accumulation in the outer cylinder of the cyclone separation, and there is also the possibility of back-mixing and diffusion and escape to the overflow cylinder. Therefore, how to discharge and separate in a timely manner It is a technical problem in the prior art that the particles after the dust discharge to the dust outlet

Embodiment 1

[0043] For the technical problems existing in the existing technology, please refer to Figure 1-11 , the present invention provides a cyclone separator 100, which includes:

[0044] Cyclone separation cylinder 110, its upper side communicates with tangential air passage 120; Said tangential air passage 120 has an airflow guide path, and is tangent to the side of said cyclone separation cylinder 110 to guide the air with particles After forming an airflow consistent with the direction of the tangential air duct 120, it enters the cyclone separator 110 tangentially to form a rotating airflow, that is, a cyclone airflow;

[0045] The centripetal force redirection channel is arranged in the upper part of the cyclone separation drum 110 and communicates with the tangential air channel 120, so that the centripetal force direction of the rotary airflow after the rotary airflow enters the centripetal force redirection channel occurs. Change to the upper side of the wall support forc...

Embodiment 2

[0068] The present invention also provides a method for cyclone separation and dust removal, which includes the following steps: guiding the air with particles into an airflow consistent with the tangential direction of the cyclone separation cylinder, and then entering the cyclone separation cylinder tangentially to form a rotating airflow; Changing the direction of the centripetal force of the rotating airflow to the upper side of the direction of the supporting force of the wall of the cyclone separation cylinder, so that the particles are subjected to a downward component force directed towards the dust outlet of the cyclone separation cylinder, so as to pull the separated particles discharge.

[0069] After the existing downstream cyclone separation components in the industry have been used for a period of time, a large amount of dust has accumulated in the cyclone separation cylinder, and there is also dust accumulation outside the overflow cylinder. However, the industry...

Embodiment 3

[0074] Please refer to Figure 12-19 , the present invention also provides a cyclone separation device, which includes an upstream cyclone separation assembly 210 and a downstream cyclone separation assembly 220, and the upstream cyclone separation assembly 210 and the downstream cyclone separation assembly 220 are communicated through a guide path; The assembly 220 includes at least one cyclone ring 221 , and each of the cyclone rings 221 includes a plurality of cyclone separators 100 as described in the first embodiment.

[0075] Please refer to Figure 13 , 14, as an embodiment of the arrangement of the cyclone separators 100, the plurality of cyclone separators 100 may be arranged in a ring to form a set of cyclone rings 221 . The cyclone separators 100 in the cyclone ring 221 are arranged circumferentially along the ring wall 2221 of the cyclone bracket 222 of the cyclone separation device. In some embodiments, the tangential air channel 120 of the cyclone separator 10...

Abstract

The invention discloses a cyclone separator and cleaning equipment. The cyclone separator comprises: a cyclone separation cylinder, the upper side of which is connected with a tangential air channel; It communicates with the air duct, so that the direction of the centripetal force of the revolving air flow after entering the centripetal force redirecting channel changes to the upper side of the direction of the supporting force of the cyclone separation cylinder wall. The cyclone separator of the present invention can effectively discharge the separated particles out of the dust outlet in time and quickly through the combination of the tangential air channel and the redirection channel, which not only solves the technical problems described in the above-mentioned background technology , and avoid the possibility of back-mixing and diffusion caused by the accumulated particles, and at the same time ensure that the cyclone separation cylinder is in a clean state without particle accumulation, which helps to improve the separation and purification effect and service life.

Description

technical field [0001] The invention relates to the technical field of cyclone separation, in particular to a cyclone separator and cleaning equipment. Background technique [0002] Cleaning appliances such as vacuum cleaners with cyclones are known prior art. Generally, in a cyclone vacuum cleaner, the air carrying dirt and dust enters the first cyclone separator through a tangential inlet, and the dirt is separated by centrifugal force into the collection chamber, and the cleaner air passes through the collection chamber. The chamber enters the second cyclone, which separates finer particles such as dirt and dust than the first cyclone. The existing second cyclone separator mainly includes a cyclone separation cylinder and an overflow cylinder, and an appropriate space is left between them, so that the dust-laden gas forms a swirling airflow belt between the two, and the particles with large mass are thrown towards the cyclone under the action of centrifugal force. The g...
