Described rotary screen cylindrical shell has 5 °～7 ° angle with horizontal plane.
Described rotary screen cylindrical shell feed zone, its length is 1/4～1/2 of cylindrical shell length L.
Described feed zone and discharging section are provided with the raising material unit that becomes 10 °～15 ° of angles with axis along inner barrel.
Described raising material unit is made up of the waveform batten of the different design of 20～30 Gents, waveform batten and cylinder inboard wall welding.
Described sieve aperture section, its length are 1/3～1/2 of cylindrical shell length L, and the expanded view diameter of sieve aperture is the hole, garden of Φ 60～80mm.
Described discharging section, its length are 1/4～1/2 of cylindrical shell length L.
What particularly point out is the raising material unit of above-mentioned setting.With the rotation of cylindrical shell, waterfall fell after raising material unit took rubbish to certain altitude, was taken up by the raising material unit in road, back again.Rubbish in the process of advancing constantly waterfall fall, stir, pass.Because capacity, particle diameter and the shape of each component of rubbish are different, its speed at the aggregate motion state is also different, be adsorbed on surplus separated the screening out in kitchen on plastics paper and combustible surface, the less non-combustible of particle diameter is screened out simultaneously, the non-combustible of separated non-greater particle size is pushed discharging opening to along raising material unit, improves as far as possible to enter the plastics paper of cyclone separator and the Lower heat value of combustible.
Aspiration channel, stretch into the discharging section position from the rotary screen barrel discharge hole outside, the outlet of aspiration channel is connected with cyclone separator, there is an aspiration channel stent support at the aspiration channel middle part, the diameter of aspiration channel is according to output, rubbish unit weight and moisture calibration, air draught mouth of pipe projected area is 2 times of aspiration channel area, and the air draught mouth of pipe and rotary screen cylinder inboard wall have 150～200mm spacing; Correct position is adjusted in position in inlet scoop and the drum screen cylindrical shell, the necessary deburring polishing of all weldments, and the aspiration channel wind speed is 15～20m/s.
Described transmission mechanism, comprise buncher, power transmission shaft, cardan-shaft suspension, rotary screen cylindrical shell support roller, wherein, buncher and cardan-shaft suspension are loaded on the rotary screen support, buncher output shaft sprocket wheel and power transmission shaft upper sprocket wheel are by chain drive, power transmission shaft passes support roller, and cardan-shaft suspension is connected with the rotary screen support, and support roller rolls with the cylindrical shell of rotary screen and is connected.
Superior effect of the present utility model is:
Rotary screen cylindrical shell and horizontal plane have one 5 °～7 ° angle, be provided with feed zone, sieve aperture section and discharging section in the cylindrical shell, be provided with the raising material unit that becomes 10 °～15 ° of angles with axis at inwall, under rotary screen rotates, make rubbish in cylindrical shell, be in the motion state that waterfall falls, stirs, passes always; The air draught mouth of pipe and cylindrical shell have certain distance, thereby screening and selection by winnowing efficient are reached more than 94%.
