Description

A kind of refuse breaking, broken bag, screening integral machine

The utility model relates to a kind of refuse breaking, broken bag, screening integral machine.

In the series of processes technology of rubbish, screening is a link the most basic, and the conventional screen subset that at present domestic destructor plant adopts is vibratory sieve and rotary screen, all is by the gravity screening; When domestic waste unit weight ratio hour, screening efficiency is very poor, and sieve aperture easily stops up; Especially when the more need of coal ash in the rubbish sift out, the easier obstruction of little sieve aperture (φ 10～13); Southern area is because of the moistening rubbish of weather when moist, and rubbish can harden and can't sieve, and the some places rubbish of will marching into the arena leaves standstill and stacks dryly, just sieves after a couple of days, and the rubbish pre-process need increase warehousing and sanitary condition extreme difference like this.In addition, all adopted bagged garbage, before the screening operation, must be provided with the broken bag device because most of municipal refuse is thrown in; The destructor plant that has disposes powerful bag-breaking machine, can make sorting difficulty behind the rubbish overcrushing, and twines easily; The drum-type garbage bag breaking machine of the destructor plant introduction of foreign technology that has, but arrange loaded down with trivial details, take up an area of many, involve great expense.

The purpose of the utility model pin provide a kind of can be to bagged garbage, moist rubbish, coal ash rubbish are well on the refuse breaking, broken bag, screening integral machine of screening to remedy the deficiency of prior art

The purpose of this utility model is achieved in that a kind of refuse breaking, broken bag, screening integral machine, it is characterized in that: the rotary screen rotary body that is supported by support roller is set, in rotary screen rotary body upper front end feed hopper is arranged, on the rotary screen rotary body circumference sieve aperture is arranged, vertically be furnished with blade in the rotary screen rotary body circumference, the rotary screen rotary body is by motor, and reductor and chain drive, off-centre is provided with the rotating screw rotating shaft in the rotary screen rotary body, and axle is provided with 2～4 road spirals.The pitch of spiral progressively reduces, by motor by decelerator and the transmission of belt pulley double reduction.

Owing to the utlity model has said structure, make the utlity model has and force the screening function, especially be fit to moist rubbish and sieve its screen rate 〉=95%; Has the broken bag function, broken bag rate 〉=90%; Have the soft broken function of selectivity, can be with garbage, melon and fruit class refuse breaking also sifts out, and can not cause masonry, the overcrushing of glass, battery class and can't sort the fertilizer system that enters; Can have the function of screening dirt according to the configuration of rubbish component needs; Multi-functional machine, minimizing equipment takes up an area of and conveying equipment, has saved investment greatly; Have anti-jamming, do not stop up, do not twine function, treating capacity 30 * 100m ³/ hour.

Below by embodiment, and in conjunction with the accompanying drawings the utility model is further described:

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is that the A of Fig. 1 is to view.

Embodiment:

A kind of refuse breaking, broken bag, screening integral machine, the rotary screen rotary body 2 that setting is supported by support roller 1, internal diameter 1400mm, effectively sieving length is 2500～3000mm (being 3500mm when screening coal ash), in rotary screen rotary body 2 upper front end feed hopper 3 is arranged, on rotary screen rotary body 2 circumference sieve aperture 4 is arranged, vertically be furnished with antifriction alloy blade 5 in rotary screen rotary body 2 circumference, equipment length overall 7578mm, configuration 18.5kw motor, back by slowing down by chain 6 transmissions, 28 rev/mins of drum rotation speeds.Arranged off-centre rotating screw rotating shaft 7 in rotary screen rotary body 2 is arranged 2～4 road spirals on the axle 7.Screw shaft is made by abrasion-proof manganese steel, and pitch progressively reduces; Pass through decelerator 8 and belt pulley 9 double reduction transmissions by the 22.5kw motor, 40 rev/mins of rotating speeds, the direction of rotation of its rotation direction and rotary screen rotary body 2, the rotating screw two ends are supported by thrust bearing 10.

After waste logistics enters rotary screen rotary body 2 by feed hopper 3, under the promotion of gravity effect and spiral, constantly be extruded screening and lifting, when being extruded, all the being forced to property screenings of material less than sieve aperture 4 drop out from sieve aperture 4.Meanwhile, the blade 5 on the rotary screen rotary body 2 cooperates shearing with spiral, refuse bag is scratched, squeezes broken, reaches the broken bag effect, but and will be greater than the broken material of sieve diameter, as melon and fruit, the surplus class in kitchen etc., brokenly also sift out.Increase spiral in screw shaft 7 screening section, reduce pitch and guaranteed above-mentioned functions.For preventing the stuck of two rotary bodies, screw shaft 7 centers are eccentric downwards with respect to rotary screen rotary body 2 centers, so when material below, when just the stenosis of logistics corridor is stuck, two rotary bodies block because of the gap increases to free fast after turning over an angle, and this has just prevented the generation of overcrushing phenomenon.Whole rotating screw can not form winding because of smooth excessiveness, but may twine axle journal and tail end at spiral rear end rubbish, so increased the backpitch device in screw shaft 7 rear ends in design, it can not twined.
