Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments based on the embodiments of the present invention, which can be realized by a person skilled in the art without any inventive step, are within the scope of the present invention.
Examples
As shown in fig. 1, the present invention provides a dust head ventilation and dust collection device, comprising: a cylinder 100 having a narrowed first outlet 110 at one end thereof; an induced draft cover 200 covering the first air outlet 110; the induced draft cover 200 is adapted to be externally connected to a dust collecting device to suck the powder ejected from the first air outlet 110. In the present embodiment, the narrowed first air outlet 110 refers to: the diameter of the first air outlet 110 is smaller than that of the cylinder 100.
This powder head raise dust collection device that takes a breath installs behind the gas outlet of powder head, and induced air cover 200 forms the negative pressure in the top of first gas outlet 110, and the powder leaves can follow barrel 100 after the gas outlet and removes, gets into induced air cover 200 from the first gas outlet 110 of narrowing, can greatly reduce the raise dust.
As shown in fig. 1, in order to further reduce the dust emission, a cloth cover may be provided on first air outlet 110, and for this purpose, a convex rib 111 for catching a cloth binding member is provided on an outer wall of first air outlet 110. For example, after the cloth cover is sleeved on the first air outlet 110, the cloth cover can be tightened by a rubber band, and the rubber band can be clamped by the convex ribs 111 to prevent the cloth cover from falling off.
In order to improve the dust collection effect, the air inlet end of the induced draft housing 200 is in a horn shape, and the diameter of the air inlet end of the induced draft housing 200 is larger than that of the first air outlet 110.
As shown in fig. 2 and 3, in order to further reduce the dust, the dust head ventilation dust collecting device may further include: an overflow preventing cover 300 covering the first air outlet 110; a second air outlet 310 is formed in the cover surface of the anti-overflow cover 300; the sidewall of the overflow preventing cover 300 is connected to the barrel 100 to form a dust buffer chamber 320 between the overflow preventing cover 300 and the first air outlet 110; the induced draft housing 200 covers the overflow preventing cover 300, and the diameter of the air inlet end of the induced draft housing 200 is greater than that of the second air outlet 310. After the anti-overflow cover 300 is arranged, when the powder is entrained by the airflow and flushed out of the first air outlet 110, the scattered powder can be blocked back by the anti-overflow cover 300, and floats in the dust buffer cavity 320 and is sucked by the air draft cover 200.
