Background technique

In industrial production, the separation and filtration of dust in the air has always been a difficult problem. Cyclone separation is the most commonly used dust separation technology.

Example 1

As shown in FIG. 1 , an embodiment of the present application provides a particle dust separation and collection device, including: a cylinder body 10 , a centrifugal fan blade 20 and a dust collection port 30 ;

The cylinder body 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 20 is disposed inside the cylinder 10 and close to the top 101 of the cylinder 10; wherein the centrifugal fan 20 can be self-driven or externally driven; when the centrifugal fan 20 is self-driven, The centrifugal fan 20 has its own driving device, and the driving device can be powered by itself or an external power supply;

The dust collecting port 30 is located at the junction of the bottom end 102 of the cylinder body 10 and the side wall 103;

The top end 101 of the cylinder body 10 is provided with an air outlet 40;

The bottom end 102 or the side wall 103 of the cylindrical body 10 is provided with an air inlet 50 .

As shown in FIG. 2 , the centrifugal fan 20 rotates under the action of its own driving force or external driving force to form an outer spiral airflow 011 , and the outer spiral airflow 011 rotates along the side wall 103 of the cylinder 10 and moves to the bottom end 102 After reaching the bottom 102 end of the cylinder 10, the rotation radius of the outer spiral airflow 011 becomes smaller, and moves to the center to form the inner spiral airflow 012. After the fan blade 20, it is accelerated again, the rotation radius is increased, and it moves outward to form an outer spiral airflow, and the cycle is repeated. The rotation directions of the two airflows are the same as the rotation directions of the centrifugal fan blades, but the translational directions of the two spiral airflows are opposite.

When in use, the exhaust port 40 can be connected to an external exhaust device. Under the action of the exhaust device, the air in the inner cavity of the cylinder body 10 will move to the top 101 and flow out of the cylinder body 10 through the exhaust port 40, so that the cylinder body The inner cavity of 10 forms a certain negative pressure, and the dust-laden airflow flows into the inner cavity of the cylinder body 10 through the air inlet 50 under the action of the negative pressure, and merges into the circulating air flow of the inner cavity of the cylinder body 10 . The dust in the inner spiral airflow 012 moves outward under the action of centrifugal force, and merges into the outer spiral air flow 011, and the dust in the outer spiral air flow 011 moves to the side wall 103 of the cylinder 10 under the action of centrifugal force, and It is pushed to the bottom end 102 of the cylinder body 10 by the airflow, and flows to the dust collection port 30 under the combined action of centrifugal force and gravity, thereby realizing the function of dust separation and collection.

In addition, the cylinder body 10 of the present application has different characteristics in different placement modes, and different placement modes can be selected according to process requirements.

The cylinder can be placed horizontally or vertically or inclined. When the cylinder is placed vertically or inclined, the top of the cylinder is upward. When the cylinder is placed horizontally or obliquely, the opening direction of the dust collecting port 30 is downward.

Method 1: The cylinder body 10 is placed vertically, that is, the central axis of the cylinder body 10 is vertical to the ground. The advantage is that when the cylinder body 10 is placed vertically, the downward gravity on the dust will help it move to the bottom of the cylinder body, which can reduce hanging on the wall. It is beneficial to clean the residual dust on the wall of the cylinder after shutdown; the cylinder body 10 can be directly connected with the dust-generating equipment to simplify the structure; it can reduce the area occupied by the equipment. The disadvantage is that the overall equipment is relatively high, which is not conducive to maintenance.

Method 2: The cylinder 10 is placed horizontally. The advantages are: the overall height of the equipment is low, easy to maintain, and the height of the workshop is not high; Local accumulation in the cylinder body 10 will not be caused. The disadvantage is that it occupies a large area.

Method 3: The cylinder is placed obliquely, taking into account the characteristics of vertical placement and horizontal placement.

Optionally, the outer part of the cylinder body 10 of the present application is configured with a placement bracket adapted to the cylinder body. When the cylinder body 10 is placed on the placement bracket, the cylinder body 10 presents a predetermined inclination angle. The inclination angle is between 30 degrees and 75 degrees, preferably 45 degrees.

As an optional embodiment, the particle dust separation and collection device further includes: a drive shaft 60;

In the present application, centrifugal fan blades are used to output power to drive the airflow to rotate and form a circulating rotating airflow, and the dust separation effect is less affected by the inlet wind speed. On the other hand, the dust collecting port of the present application is located at the junction of the side wall and the bottom end. The wind pressure at the dust collecting port is large, and the dust flows to the dust collecting port under the dual action of gravity and centrifugal force, so the dust collection effect is better.

With this opening method, the dust-laden gas can travel the longest distance in the cylinder, so the dust separation effect is the best. Preferably, the side wall air inlet is tangent to the side wall of the cylinder, and the direction of the air inlet is consistent with the rotation direction of the fan blade, which can further improve the rotation speed of the airflow in the cylinder. The disadvantage of this opening method is that the dust has a large wind pressure loss on the inner wall of the cylinder. Based on the above factors, the side wall opening is suitable for the low dust content and fine dust process occasions.

Opening method two:

As an optional embodiment, the air inlet 50 includes: a second air inlet 502 is also called a manifold air inlet; the second air inlet 502 is opened on the pipe connected to the dust collection port 30, and passes through the The dust collection port 30 is communicated with the cylinder body 10; this opening method can make a large amount of dust flow directly into the dust collection container connected to the dust collection port under the action of gravity, and only a small amount of dust enters the cylinder body, thereby reducing dust The contact with the cylinder is suitable for process occasions with large dust content.

Opening method three:

As an optional embodiment, the air inlet 50 includes: a third air inlet 503 is also called a bottom air inlet; the third air inlet 503 is opened at the bottom end 102 of the cylinder 10; the The outer edge of the third air inlet 503 is spaced from the side wall 103 of the cylindrical body 10 by a predetermined distance, and the predetermined distance is greater than 10% of the length of the radius of the cylindrical body 10 . With this opening method, the air pressure at the air inlet is at a lower point, which is lower than the air pressure at the dust collection port. When the air inlet and the dust collection port are connected to the same working chamber, the dust collection port can realize automatic backflow, which is especially suitable for For process occasions where dust reflow is required.

The solution of this application can select at least one of the above-mentioned opening methods.
