Example one
As shown in fig. 1, an embodiment of the present application provides a particulate dust separating and collecting apparatus, including: a cylinder 10, a centrifugal fan blade 20 and a dust collecting opening 30;
the cylinder 10 is a cylindrical closed container structure composed of a top end 101, a bottom end 102 and a side wall 103;
the centrifugal fan blade 20 is arranged inside the cylinder 10 and close to the top end 101 of the cylinder 10; wherein, the centrifugal fan blade 20 can be self-driven or externally driven; when the centrifugal fan blade 20 is self-driven, the centrifugal fan blade 20 is provided with a driving device, and the driving device can be self-powered or externally connected with a power supply for supplying power;
the dust collecting opening 30 is positioned at the joint of the bottom end 102 and the side wall 103 of the cylinder body 10;
an air outlet 40 is formed in the top end 101 of the cylinder 10;
the bottom end 102 or the side wall 103 of the cylinder 10 is provided with an air inlet 50.
As shown in fig. 2, the centrifugal fan blade 20 rotates under the action of its own driving force or external driving force to form an outer-ring spiral airflow 011, the outer-ring spiral airflow 011 rotates along the side wall 103 of the cylinder 10 and moves to the bottom end 102, when reaching the bottom end 102 of the cylinder 10, the rotation radius of the outer-ring spiral airflow 011 decreases and moves to the center to form an inner-ring spiral airflow 012, the inner-ring spiral airflow 012 moves toward the centrifugal fan blade 20 while rotating, and when reaching the centrifugal fan blade 20, the inner-ring spiral airflow is accelerated again, the rotation radius increases and moves outward to form an outer-ring spiral airflow, and the above-mentioned steps are repeated. The rotation directions of the two air flows are consistent with the rotation direction of the centrifugal fan blade, but the translation directions of the two spiral air flows are opposite.
When the dust-containing air circulation air purifier is used, the air outlet 40 can be externally connected with an air exhaust device, under the action of the air exhaust device, part of air in the inner cavity of the cylinder 10 can move towards the top end 101 and flows out of the cylinder 10 through the air outlet 40, so that a certain negative pressure is formed in the inner cavity of the cylinder 10, and dust-containing air flows into the inner cavity of the cylinder 10 through the air inlet 50 and is merged into the circulation air flow in the inner cavity of the cylinder 10 under the action of the negative pressure. The dust in the inner spiral airflow 012 moves outwards under the action of the centrifugal force and merges into the outer spiral airflow 011, and the dust in the outer spiral airflow 011 moves towards the sidewall 103 of the barrel 10 under the action of the centrifugal force and is pushed towards the bottom end 102 of the barrel 10 by the airflow and flows towards the dust collection port 30 under the combined action of the centrifugal force and the gravity, so that the dust is separated and collected.
In addition, the barrel 10 of the present application has different characteristics due to different placement modes, and different placement modes can be selected according to process requirements.
The barrel can be horizontally placed or vertically placed or obliquely placed, and when the barrel is vertically or obliquely placed, the top end of the barrel faces upwards. When the drum is placed horizontally or obliquely, the dust collection port 30 is opened downward.
The first method is as follows: the cylinder 10 is vertically placed, that is, the central axis of the cylinder 10 is vertical to the ground, which has the following advantages: when the dust collecting device is vertically placed, downward gravity borne by dust is beneficial to the dust to move to the bottom end of the cylinder body, so that wall hanging can be reduced, and residual dust can be cleaned from the cylinder wall after the machine is stopped; the cylinder 10 can be directly connected with dust production equipment, so that the structure is simplified; the area occupied by the equipment can be reduced. The disadvantages are that: the equipment is overall higher and is not beneficial to maintenance.
The second method comprises the following steps: the barrel 10 is horizontally arranged, and has the advantages that: the overall height of the equipment is low, the maintenance is easy, and the requirement on the height of a workshop is not high; the dust collecting effect is good, and the dust is easy to move to the dust collecting opening under the dual action of gravity and centrifugal force, so that the local accumulation in the barrel body 10 can not be caused. The disadvantages are that: the occupied area is large.
The third method comprises the following steps: the barrel is obliquely arranged, and the characteristics of vertical arrangement and horizontal arrangement are considered.
Optionally, the barrel 10 of the present application is externally provided with a placing support adapted to the barrel, and when the barrel 10 is placed on the placing support, the barrel 10 has a predetermined inclination angle, optionally, the predetermined inclination angle is between 30 degrees and 75 degrees, and preferably 45 degrees.
As an optional embodiment, the particulate dust separating and collecting apparatus further comprises: a drive shaft 60;
the driving shaft 60 extends through the top end of the cylinder 10 to the inside of the cylinder 10; and, the driving shaft 60 is located on the central axis of the cylinder 10; the centrifugal fan blade 20 is arranged on the driving shaft 60; the centrifugal fan blade 20 is driven by the driving shaft 60 to rotate.
This application adopts centrifugal fan blade output power, and the drive air current is rotatory to form the rotatory air current of circulation, the dust separation effect receives the influence of air inlet wind speed less. On the other hand, the combination department of lateral wall and bottom is located to this application dust collection mouth, and dust collection mouth department wind pressure is big, and the dust receives the dual-action flow direction dust collection mouth of gravity and centrifugal force, therefore the effect of collecting the dust is better.

The opening mode is selected, so that the travel distance of the dust-containing gas in the cylinder body is longest, and the dust separation effect is best. Preferably, the side wall air inlet is tangent to the side wall of the cylinder, the air inlet direction is consistent with the rotation direction of the fan blades, and the air flow rotation speed in the cylinder can be further improved. The disadvantages of this opening method are: the dust has large abrasion to the inner wall of the cylinder body and large wind pressure loss. Combining the above factors, the side wall opening is suitable for the technological occasions with lower dust content and finer dust.
The second opening mode:
as an alternative embodiment, the intake vent 50 includes: the second intake vent 502 is also referred to as a manifold vent; the second air inlet 502 is arranged on a pipeline connected with the dust collecting port 30 and communicated with the cylinder 10 through the dust collecting port 30; by adopting the opening mode, a large amount of dust can directly flow into the dust collecting container connected with the dust collecting opening under the action of gravity, and only a small amount of dust enters the barrel body, so that the contact between the dust and the barrel body is reduced, and the dust collecting device is suitable for technical occasions with large dust content.

By adopting the opening mode, the air pressure at the air inlet is at a lower point and is lower than the air pressure of the dust collecting opening, when the air inlet and the dust collecting opening are connected with the same working chamber, the dust collecting opening can realize automatic backflow, and the dust collecting device is particularly suitable for process occasions needing dust backflow.
In the scheme of the present application, at least one opening manner may be selected, and for convenience of understanding and illustration, three opening manners are shown in fig. 1 of the present application at the same time, but it should be understood that one opening manner, or any two opening manners or three opening manners at the same time may be adopted in the present application.
