Description
Technical field
Patent of the present invention relates to a kind of processing solid waste and separates sorting unit and method, is specifically related to a kind of device and method for sorting consumer waste.
Background technology
The annual production of China's domestic waste is near 1.5 hundred million tons at present, China has 2/3 city to be absorbed in the predicament in house refuse besieged city approximately, not only affect urban look, and have a strong impact on people's health, house refuse has become the thorny problem of urban development.
Be the living environment of to protect mankind, the processing of house refuse is more and more important, and at present the processing mode of domestic waste comprises that the modes such as burning, landfill and compost process.And because the domestic waste particle size differences is large, the characteristics such as complicated component, moisture height adopt burning, landfill and compost treatment all must carry out sorting before, to satisfy the needs of subsequent treatment.And wherein rotary screen is to use more a kind of particle diameter screening sorting unit, adopts rotary screen to sieve processing, and the small particle diameter house refuse is sifted out, and enters operation of lower step and carries out advanced treating.
The sieve aperture of conventional rollers sieve mostly is square hole, and percent opening is lower, generally is lower than 70%; Therefore require the humidity of screening materials carrying generally to be not more than 10%, because humidity is excessive, can increase the viscosity that is sized material in addition, stop up sieve aperture or stick on the cylinder.The conventional rollers sieve often the phenomenons such as obstruction, bridging can occur after using a period of time, cause screening efficiency to descend, and has a strong impact on the normal operation of equipment.Traditional rotary screen can require certain gradient when installing, because house refuse enters in the cylinder from a high end, under Action of Gravity Field, move to the front lower place, but the inclination installation difficulty is higher, and because unbalance stress easily causes mechanical unstability, the problem such as motor damage and noise are larger.
Summary of the invention
The present invention is directed to sieve aperture shape, the percent opening mentioned in traditional separating cylinder screen device low, process that the high house refuse efficient of humidity and adhesiveness is low, noise is large and the problem such as the motor damage is serious, provide a kind of simple in structure, easy to maintenance, the domestic waste sorting device that screening efficiency is high and method.
Domestic waste sorting device involved in the present invention mainly is comprised of telescopic roller brush (1), cylinder (2), reductor (3), motor (4), scalable scraper plate (5), base (6), sieve aperture (7), deflector (8), screenings hopper (9), oversize outlet (10) etc.
Wherein telescopic roller brush (1) is installed on the support of cylinder one side, can free horizontal extension, and length is consistent with drum length; Cylinder (2) is the main body of rotary screen, rotates around central shaft under driven by motor, and the length of cylinder is 5-12m, and diameter is 2m; Reductor (3) links to each other with motor, can regulate the rotating speed of control centre's axle; Motor (4) provides power for package unit; Scraper plate (5) is installed in the opposite side of telescopic roller brush, and length is consistent with drum length, is used for removing the part bur that round brush can not be cleared up; Base (6) mainly plays a supportive role to whole system; Sieve aperture (7) is opened on cylinder (2), is the circular hole of diameter 80mm, and the percent opening of whole cylinder is at 75%-85%; Deflector (8) is installed in the cylinder, is screw type, and the width of deflector is 40mm; Screenings hopper (9) is installed in the cylinder bottom, is back taper, and its lower end outlet is connected on the feed conveyor belt of back-end processing; Oversize outlet (10) is installed in the other end of rotary screen charging aperture.
The method for sorting consumer waste that the present invention relates to is mainly realized by following steps:
At first a whole set of cylinder screen device level is installed, then starter motor and reductor, the velocity of rotation of index drum is 10-12r/min, beginning adds the house refuse that needs sorting in charging aperture.House refuse in cylinder along the deflector forward travel of spinning, granularity is passed sieve aperture less than the house refuse of 80mm under the effect of gravity and centrifugal force, enter the screenings hopper, enter down treatment process one, and granularity is advanced along drum turning greater than the house refuse continuation of 80mm, until enter the oversize outlet.After whole rotary screen smooth operation a period of time, some house refuses that humidity and viscosity are larger can be blocked the part sieve aperture or stick on the cylinder, the telescopic roller brush of cylinder one side moves to cylinder and contacts at this moment, telescopic roller brush can put in sieve aperture, the material of sieve aperture is stopped up in cleaning, when occurring sticking to the bur of cylinder outer wall, scraper plate is scalable to and cylinder surface, and bur is struck off.By the obstruction on the cooperation removing sieve aperture of above telescopic roller brush and scraper plate and the house refuse of adhesion, guarantee that sieve aperture is unimpeded.
Domestic waste sorting device provided by the invention and method have following obvious superiority:
(1) sieve aperture of apparatus of the present invention is circular hole, and the aperture is 80mm, and percent opening is 75%-85%, than the low percent opening cylinder screen device of traditional square, but the Effective Raise screen rate.
(2) apparatus of the present invention are loaded onto respectively telescopic roller brush and scraper plate and can be removed quickly and easily tamper in the sieve aperture and the bur on the cylinder in the rotary screen both sides, need labor cleaning's tamper and bur than the conventional rollers sieve, plenty of time and cost have been saved, effectively the even running of assurance device.
(3) the rotary screen level that provides of apparatus of the present invention is installed, in cylinder inside deflector is housed, allow the house refuse in the cylinder advance along the deflector upset, avoided the conventional rollers sieve to tilt the unbalance stress that causes is installed, cause noise large and to problems such as the damage of motor are serious.
(4) method for sorting consumer waste provided by the invention is simpler, stable, quick than the method for traditional life refuse classification.By each parts cooperation of cylinder screen device, can guarantee the energy-efficient running of whole rotary screen, screening efficiency is apparently higher than conventional method simultaneously.
Description of drawings
Fig. 1 is the schematic diagram of domestic waste sorting device rotary screen.
Among the figure, formed by telescopic roller brush (1), cylinder (2), reductor (3), motor (4), scalable scraper plate (5), base (6), sieve aperture (7), deflector (8), screenings hopper (9), oversize outlet (10) etc.
The specific embodiment
Application example with reference to this device and method of elaboration shown in Figure 1.
Send in the cylinder by charging aperture through the domestic waste of collecting, under deflector rotarily drives, make house refuse in the forward travel of cylinder inside spin.Particle diameter is lower than the house refuse of 80mm under the effect of gravity and centrifugal force, pass sieve aperture and enter the screenings hopper, and particle diameter can not pass sieve aperture greater than the house refuse of 80mm and continues to overturn in cylinder and advance, until enter the oversize outlet, until granularity is lower than 80mm, can pass through sieve aperture, enter the screenings hopper and be for further processing.When the clogging sieve aperture of part house refuse or when sticking to cylinder body outer wall, telescopic roller brush moves to cylinder with scraper plate and contacts, and just can effectively remove tamper in the sieve aperture and the bur of cylinder outside.The rotating speed of index drum sieve is 12r/min, and house refuse is after sorting, and granularity is lower than the efficiency of separation of 80mm house refuse up to 93%.
