Preferably, the top of the dust collecting pipe is a dust discharging pipe butt joint, and the end face of the dust discharging pipe butt joint is an inclined plane.

Preferably, the dust collecting pipe is a circular pipe.

Preferably, the angle between the side of the conical cover and the dust falling direction is 40-60 °.

Preferably, the air outlet holes are positioned at the top of each layer of the conical cover.

Preferably, the conical cover is made of stainless steel.

Preferably, along the dust descending direction, the plurality of dustproof spacing rings comprise a first dustproof spacing ring, a second dustproof spacing ring and a third dustproof spacing ring, and projections of the first dustproof spacing ring, the second dustproof spacing ring and the third dustproof spacing ring along the dust descending direction are concentrically arranged.

In the above technical solution, the working principle of the stacked directional dust cover provided by the present invention is as follows: utilize the characteristics of dust dead weight, the dust gets into and connects the dirt pipe after, through a plurality of conical cover in proper order under the effect of gravity, because the lateral wall of conical cover is the toper, thereby can accelerate the effect of subsiding of dust, thereby under the guide effect of dustproof spacer ring, conical cover, also can prevent spilling over of dust effectively, thereby guaranteed that the operation room has good operational environment, simultaneously, also can realize regularly exhausting through the venthole, prevent that the dust cover internal gas pressure from too big causing the damage to the dust cover. The dust cover completely adopts a mechanical mode to deposit dust without other electrified machines, thereby achieving the effects of energy conservation and environmental protection.

Additional features and advantages of the utility model will be set forth in the detailed description which follows.

Detailed Description

The following detailed description of embodiments of the utility model refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, unless otherwise specified, the directional words "upper, lower, inner, outer" and the like included in the terms merely represent the orientation of the terms in a conventional use state or are colloquially understood by those skilled in the art, and should not be construed as limiting the terms.

The utility model provides a stacked directional dust cover, which comprises a dust receiving pipe 2 and a plurality of dust isolating rings in sequence along the dust falling direction as shown in figure 1; moreover, along the dust descending direction, the size of the dustproof spacing ring is gradually increased; the adjacent dustproof spacer rings are connected through a conical cover 6, and an air outlet 7 is formed in the conical cover 6.

The working principle of the stacked directional dust cover is as follows: utilize the characteristics of dust dead weight, the dust gets into and connects dirt pipe 2 back, through a plurality of conical cover 6 under the effect of gravity in proper order, because the lateral wall of conical cover 6 is the toper, thereby can accelerate the effect of subsiding of dust, thereby at dustproof spacer ring, under conical cover 6's guide effect, also can prevent spilling over of dust effectively, thereby guaranteed to have good operational environment between the operation, and simultaneously, also can realize regularly exhausting through venthole 7, prevent that the dust cover internal gas pressure from leading to the fact the damage to the dust cover greatly. The dust cover completely adopts a mechanical mode to deposit dust without other electrified machines, thereby achieving the effects of energy conservation and environmental protection.

In the present invention, the shape of the top of the dust collecting pipe 2 can be selected in a wide range, but in order to improve the effect of abutting the dust collecting pipe 2 and the dust exhaust pipe, it is preferable that the top of the dust collecting pipe 2 is a dust exhaust pipe abutting opening 1, and the end surface of the dust exhaust pipe abutting opening 1 is an inclined surface. The arrangement of the inclined surface is convenient for the installation and the disassembly of the dust collecting pipe 2 and the dust discharging pipe.
