Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
Example 1
A double-layer smoke dust collecting cover is shown in figures 2-6 and comprises an inner cover body 2, an outer cover body 1, a supporting piece 3, an adjusting plate 4 and an air pipe connecting piece 5;
several inner shells are assembled into an inner layer cover body 2 as shown in figure 3, and a frustum-shaped cavity is formed;
the outer-layer cover body 1 is assembled by a plurality of outer shell bodies and is larger than the inner-layer cover body 2 as shown in figure 4, and a frustum-shaped cavity is formed in the same way;
in detail, as shown in fig. 2, 5 and 6, the outer cover 1 covers the outer part of the inner cover 2 to form a conical annular channel with the inner cover, and is fixed by the supporting member 3;
as shown in figure 3, the inner layer cover body 2 is provided with ring-shaped dense small holes from bottom to top and from outside to inside, the top of the inner layer cover body 2 is provided with a square ventilation channel, and an adjusting plate 4 is additionally arranged to adjust the area of the channel and adjust the ventilation quantity at the top of the inner layer cover body 2.
The design uniformly distributes the ventilation channels at each position of the collecting cover, effectively improves the dust collecting effect of the collecting cover, and can collect the smoke at each smoke point below the collecting cover. When the smoke point is at the edge of the trapping cover, the adjusting plate 4 is adjusted to enable the top channel to be in a completely closed state, so that the wind speed of the annular small-hole channel is increased, and the trapping effect at the edge of the trapping cover is improved. When the smoke point is in the middle of the trapping cover, the top square channel is adjusted to be fully opened, and the trapping effect in the middle of the trapping cover is the best due to the fact that the resistance of the top square channel is the minimum, and smoke dust of the smoke point can be effectively trapped. When the lower edge and the middle position of the trapping cover are provided with smoke points, the adjusting plate 4 is in a half-open state, and the actual adjusting amount is related to the actual state of the working condition.
Example 2
A double-layer smoke dust collecting cover is shown in figure 1 and comprises an inner cover body 2, an outer cover body 1, a supporting piece 3, an adjusting plate 4 and an air pipe connecting piece 5; small holes in a gradient annular layout are formed in the inner layer cover body 2, and a frustum-shaped cavity is formed; the outer cover body 1 covers the inner cover body 2, the outer cover body 1 and the inner cover body 2 form a conical annular channel, and the inner cover body 2 and the outer cover body 1 are connected through a support piece 3; the top of the inner layer cover body 2 is provided with a plurality of square channels and is additionally provided with an adjusting plate 4; and an air pipe connecting piece 5 is arranged outside the outer layer cover body 1.
The inner cover body 2 is internally provided with echelon annular layout small holes which specifically comprise: the inner layer cover body 2 is provided with annular dense small holes from bottom to top in a gradient way.
The supporting piece 3 is arranged between the outer shell 1 and the top of the inner shell 2.
Each square channel of a plurality of square channels all one-to-one be equipped with regulating plate 4.
The double-layer trapping cover is of a completely symmetrical structure and is formed by assembling.
As shown in fig. 7, if the collection area needs to be increased due to a change in the field conditions, the collection area can be increased by simply splicing the collection covers.
The above shows that the double-layer smoke dust collecting cover can effectively collect smoke dust below the collecting cover, and the collecting effect is obviously improved compared with that of a single-layer collecting cover.
