Detailed Description
In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will be further described with reference to the drawings attached to the specification.
As shown in fig. 1 to 4, the dust removal chute of the color sorter comprises an upper chute 1 and a lower chute 2 which are parallel and overlapped in an up-down position, wherein the bottom end of the upper chute 1 is arranged on the surface of the top end of the lower chute 2, so that the upper chute 1 and the lower chute 2 are overlapped, materials to be color sorted enter the surface of the lower chute 2 from the upper chute 1, and the problems of material leakage and the like cannot occur. A gap 10 is reserved between the bottom surface of the upper chute 1 and the surface of the lower chute 2, the gap 10 is arranged to provide an air port for a dust removing air blowing device, and at the position, a down-blowing and up-sucking mode is realized to remove the materials to be subjected to color sorting and dust in the chute. Clearance 10 sets up in chute bottom 20 ~ 40cm position under the distance, and clearance 10 sets up in chute length direction and leans on lower position more, realizes more getting rid of the dust that the material produced in the chute friction promptly, avoids the roughly dust of chute surplus overlength to produce once more, reduces the influence of dust to the look selection case as far as possible and improves the quality of look selection back material. The lower part of the gap 10 is provided with a blowing device, the materials and dust in the materials are blown up, the force of wind force is blown out through adjustment, the dust is separated from the materials, the upper part of the gap 10 is provided with a dust collection device, and the dust which is blown up and separated from the materials is sucked away through adsorption. The dust suction device comprises a cover plate 3 covering the upper part of the gap 10, and a dust suction negative pressure component is communicated with the cover plate 3. The setting of apron 3 provides a comparatively sealed environment relatively on clearance 10 upper portion for dust and material can separate in this region, also avoids the problem that the material on the chute splashes simultaneously.
In this technical scheme, lower chute 2 width is greater than upper chute 1 width and all is fixed with the look selection machine frame, is convenient for go up chute 1 and lower chute 2's overlap joint. The clearance 10 highly is 2 ~ 4mm, and the reasonable setting of clearance height can evenly get into the wind-force size on the chute on the one hand, and on the other hand avoids going up the chute and having a too big distance down between the chute, and the material appears splashing when getting into down the chute by last chute and beats the scheduling problem, ensures that the commodity circulation slides steadily. Go up chute 1 and 2 overlap joint lengths of lower chute not less than 3cm, the rational design of overlap joint length is convenient for evenly the air inlet on the one hand, and on the other hand avoids the material to leak down by clearance position problem.
Among this technical scheme, 3 width of apron is greater than down chute 2 width, and apron 3 is the U type of invering, and 3 both sides of apron are fixed through locking screw 7 and lower chute 2 side, and the loading and unloading of the apron of being convenient for, and do not influence the structure of chute in fixing. The length of the cover plate 3 is not less than 30cm, a relatively sealed environment is provided for dust removal through reasonable design of the length of the cover plate 3, dust and material separation is facilitated, the material continues to slide downwards under the action of self gravity, the dust is sucked away, and the dust removal rate is high.
In the technical scheme, the dust absorption negative pressure component comprises a plurality of dust absorption holes 4 uniformly distributed on the cover plate 3, the dust absorption holes 4 are connected with air guide pipes, and the other ends of the air guide pipes are connected with a negative pressure pump. The negative pressure pump is utilized to suck the air in the area of the cover plate 3, and the dust floating in the air is sucked away along with the air, so that the dust removal is realized.
Among this technical scheme, blast apparatus include with 2 bottom surfaces of lower chute and the fixed aviation baffle 5 in 1 bottom surface of upper chute, the equipartition is provided with a plurality of gas pockets 6 on the aviation baffle 5, is connected with the fan on the gas pocket 6. The fan blows a certain air flow to the chute through the air holes and the gap 10, the air flow impacts the materials, the materials continuously slide downwards under the action of the self weight, and dust in the materials is raised and then is sucked by the dust collection negative pressure component.
In the technical scheme, the air deflector 5 is L-shaped and is fixedly connected with the side surface of the cover plate 3 through a fastening screw 8, a rubber pad is arranged on one side surface of the air deflector 5 and is tightly attached to the bottom surface of the lower chute 2, and a rubber pad is arranged on the outer end surface of the other side surface of the air deflector 5 and is tightly attached to the bottom surface of the upper chute 1. The air deflector 5 provides a relatively sealed space for air inlet, so that the air speed entering the chute is uniform, and the problem of overlarge local wind power or undersize local wind power is avoided.
Technical solution of the invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive method concept and technical solution, or to apply the inventive concept and technical solution to other occasions without modification.
