Detailed description of the invention

Below in conjunction with accompanying drawing 1 to Figure 11, and detailed description of the invention is described further the present invention.

Embodiment 1: see Fig. 1 to Fig. 4.

A kind of cyclone separator, as shown in Figure 1 and Figure 2; Comprise and be separated cavity 1, described separation cavity 1 comprise cavity cylindrical first be separated cavity 11 and cavity tapered second be separated cavity 12, first is separated the top that cavity 11 is positioned at the second separation cavity 12, described first side being separated cavity 11 is provided with charging aperture 16, charging aperture 16 is connected with feed pipe 3, first upper end being separated cavity 11 is connected with exhaust tube 4 and one end of exhaust tube 4 is stretched in the first separation cavity 11, described first side being separated cavity 11 is provided with multiple sorting hole 13, is arranged with and accepts cavity 2 outside described separation cavity 1.

This cyclone separator both may be used for particle less in separating plastic waste material and dust; Also more short grained plastics and dust can further be isolated; This separation is conducive to the classification process of rubbish, avoids a large amount of granule plastics to topple over, contaminated environment.

When being separated for granular size, according to the needs of plastics recovery, if needs particle is more than 0.1mm at diameter, then the aperture of sorting hole 13 be set to 0.1mm or be slightly less than 0.1mm, after plastic waste enters separation cavity 1 by feed pipe 3, plastic waste can rotate along the first surface being separated cavity 11 being separated cavity 1, and the material being less than 0.1mm when the external diameter in waste material can directly be entered into by sorting hole 13 in undertaking cavity 2, thus completes separation circuit.In order to improve separating effect further, can be separated on cavity 12 second and sorting hole 13 is also set, because plastics motion in separation cavity 1, the radius of its movement locus reduces gradually, progress into second and be separated motion in cavity 12, the waste material entered in the second separation cavity 12 is separated through sorting hole 13 again, and material external diameter being less than 0.1mm is further separated, and improves separation rate.

When carrying out the less plastics of particle and dust separation, plastic grain and dust enter into simultaneously and are separated in cavity 1, because the density of plastic grain is large compared with dust, and the cross-sectional area of plastic grain in motion process is much smaller than the cross-sectional area of dust, therefore the velocity attenuation of dust is very fast, and its moving radius reduces rapidly; And plastic grain can move along the medial surface being separated cavity 1, speed decays gradually; In order to better separation, the sorting hole 13 that first is separated cavity 11 can be arranged on lower end, because dust is separated the upper end first time collision rift of cavity 11 with first, the operating radius rapid attenuation of large absolutely number drops in the second separation cavity 12.Plastic grain then can be entered into by sorting hole 13 and accept cavity 2, and plastic grain and dust separation, can contribute to refuse classification process, be conducive to environmental protection.

As shown in Figure 3, Figure 4, further, the lower end of described undertaking cavity 2 is provided with separated and collected device 6, described separated and collected device 6 comprises the container 61 be connected with undertaking cavity 2, container 61 is stretched in second lower end being separated cavity 12, be provided with the dividing plate 62 of inclination in described container 61, the middle part of dividing plate 62 is provided with the through hole matched with the second lower end being separated cavity 12, and the side of described container 61 is connected with the collection conduit communicated with the cavity of container 61.Being separated the lower end of cavity 12 for ease of second stretches in container 61, can be provided with extend pipeline 17 in the second lower end being separated cavity 12, and extending pipeline 17 can, with second to be separated cavity 12 one-body molded, also can divide body formed, by connected mode connections such as welding.

By arranging separated and collected device 6, make separator enter in different collection containers 61, it is convenient to collect.

For ease of charging, reduce material and the impact severity be separated between cavity 1, it is tangent that described feed pipe 3 and first is separated cavity 11; Feed pipe 3 is in downward-sloping setting.

For convenience of manufacturing, first is separated cavity and the second disengagement chamber body by integral forming.

Embodiment 2: see Fig. 6, Fig. 8, Fig. 9, a kind of cyclone separator, its structure difference from Example 1 is: the upper end of described sorting hole 13 is provided with and guides cap 14, and one end of described guiding cap 14 is separated cavity 11 with first and connects, and guides the other end of cap 14 to stretch into and accepts in cavity 2.

Arrange and guide cap 14 separator can be imported in undertaking chamber, as when carrying out granular size and being separated, the particle of small volume is when through sorting hole 13, enter into by guiding cap 14 and accept in cavity 2, avoid the particle of small volume when by sorting hole 13, with the sideways collisions of sorting hole 13, after long-time use, sorting hole 13 is out of shape, and reduces separation rate, inferior separating effect.When carrying out plastic grain and dust separation, also can avoid the sideways collisions of plastic grain and sorting hole 13, deformation occurs.

Further, as shown in Figure 7, Figure 8, described charging aperture 16 is arranged with flexible steel in flat section tubing 5, and feed pipe 3 is connected with charging aperture 16 by flexible steel in flat section tubing 5.

Flexible steel in flat section tubing 5 is set, makes air-flow enter the direction be separated in cavity 1 adjustable, mainly regulate angle obliquely.Air-flow enters the speed being separated cavity 1 and may change, and the design being separated cavity 1 is the internal diameter setting cavity according to a certain air-flow radial velocity, thus separator is well separated, when the radial velocity of air-flow changes, the change of dust movement track can be caused; As dust and plastic grain mixture enter, to be separated radial velocity in cavity 11 comparatively large, by regulating the setting position of flexible steel in flat section tubing 5, can make plastic grain as far as possible by sorting hole 13 region, and entered by sorting hole 13 and accept in cavity 2.Regulate air-flow to enter the radial velocity being separated cavity 1 by arranging flexible steel in flat section tubing 5, thus reach good separation rate.

Further, as shown in Figure 9, Figure 10, one end that described exhaust tube 4 stretches in the first separation cavity 11 is hook-shaped, and bleeding point is arranged upward.

When bleeding process to the air be separated in cavity 1, if bleeding point directly down, object lighter in air-flow will certainly being driven and move upward, for reducing to bleed on the impact of dust, bleeding point being arranged upwards.During in order to make to bleed, air-flow is relatively more even, and the multiple hook-shaped air inlet section 42 that exhaust tube 4 is provided with main tracheae section 41 and distributes ringwise, the outlet side of hook-shaped air inlet section 42 is connected with main tracheae section 41.The bleeding point of air inlet section 42 is arranged upward, see Fig. 9, Figure 10.

Embodiment 3: a kind of cyclone separator, see Figure 11, its structure difference from Example 1 is: described sorting hole 13 is in the setting that distributes clockwise or counterclockwise.

Separator is when through sorting hole 13, separator advances with tangential velocity, advance along guiding cap 14 for the ease of separator, and the collision reduced between sorting hole 13 and separator, sorting hole 13 can be set to distribute clockwise or counterclockwise, the length direction of sorting hole 13 is much the same or identical with the velocity attitude of separator.

Certainly, the structure in embodiment 2 also can be applied in embodiment 3.

Below be only the preferred embodiment of the application, equivalent technical solutions on this basis still falls into application protection domain.
