Description

Dry dust removal device

Technical field

The utility model relates to the field of waste recycling and treatment, and more particularly to a dry dust removing device.

Background technique

In the recycling of waste, effective measures are needed to remove impurities such as dust and particles in the waste. Taking waste paper recycling as an example, the recycled waste paper includes office waste paper, used packaging boxes, and waste cement bags. In order to realize the reuse of waste paper, it is necessary to remove impurities in the waste paper as much as possible, so that the ash content of the subsequently obtained pulp is close to the ash content (less than 5%) of the base paper.

Current waste paper processing systems include conveyors (eg, belt or chain machines), bulk machines, and D-type hydraulic pulpers. In the waste paper processing process, the waste paper first enters the bulk wrapping machine through the conveyor, and the bundled waste paper is turned over with the drum in the bulk wrapping machine, and is scattered with the top column on the inner wall of the drum, and the centrifugal force of some impurities in the drum is dispersed. Exhausted through the sieve hole. The scattered waste paper is output through a spiral plate in the drum and sent to a D-type hydraulic pulper through a conveyor. The D-type hydraulic pulper disintegrates the waste paper into pulp.

In the above-mentioned waste paper processing system, the bulk wrapping machine can only remove the impurities entrained between the surface of the waste paper and the waste paper, and it is difficult to remove the impurities wrapped in the corners of the waste paper bag. If the waste paper bag is pulped in this case, the hydroxyl groups having strong adsorption in the waste paper fragments and the fine foreign particles are adsorbed to each other, which is more difficult to remove in the subsequent screening purification system.

When at least two adjacent dust removing members of the plurality of dust removing members 20' are interlaced with each other, the fragments can be further torn.

2 shows a partial cross-sectional view of a dry dust removing device in accordance with a second embodiment of the present invention. As shown in FIG. 2, the dry dust removing device 1 includes a dust removing device body 10 and a plurality of dust removing members 20 (only two are shown in FIG. 2), and the dust removing device body 10 includes a feed port 11 and a discharge port 12. The debris requiring removal of impurities enters the dust removing device body 10 from the feed port 11, is tumbling in the dust removing device body 10 by agitation by the plurality of dust removing members 20, and is further shredded when the adjacent dust removing members 20 are staggered with each other. The impurities attached to the debris are separated from the debris during the tumbling of the debris, and The debris after the impurities are removed leaves the dust removing device body 10 from the discharge port 12.

In the embodiment shown in Fig. 2, the dust removing member 20 is traversed and hinged on the body of the dust removing device body 10 in the width direction of the dust removing device body 10. The dust removing member 20 can smash the debris in the dust removing device body 10 when rotated, so that the debris rolls in the dust removing device body 10. And the adjacent dust removing members 20 may be interlaced on the sides facing each other to further tear the fragments apart. The structure of the dust removing device 20 hinged on the body of the dust removing device body 10 makes the structure of the dry dust removing device relatively compact.
