Description

Garbage winnowing device

Technical Field

The utility model belongs to the technical field of refuse treatment's technique and specifically relates to a rubbish wind selector is related to.

Background

With the development of the technology, the treatment of the domestic garbage is changed from the original landfill treatment to the comprehensive utilization of resources, and among various treatment methods, the incineration treatment process increasingly shows the superiority and occupies the leading position at present. At present, domestic garbage in China is mostly collected in bags, the garbage contains a large number of plastic bags, and if the garbage is directly incinerated without pretreatment, the possibility of generating toxic and harmful substances such as dioxin is increased, so that before the domestic garbage is treated, light substances such as the plastic bags, foamed plastics and the like must be sorted out to be beneficial to recycling of resources and normal operation of subsequent recycling treatment processes.

The existing separation mode is that garbage is poured into a treatment box firstly, so that the garbage falls vertically due to self gravity, then a plastic bag in the garbage is punctured by two groups of licker-in rollers, and light substances such as the plastic bag, foamed plastic and the like are blown out into a collection box communicated with the treatment box by a fan, so that the separation of the light substances is realized.

However, since the falling speed of the garbage mixed with the light materials is high, the effect of the treatment method of blowing off the light materials by the fan is not good, and sometimes, the separation is performed for many times, and the efficiency is low, so that improvement is needed.

SUMMERY OF THE UTILITY MODEL

After the garbage enters the collection box 52, the motor 313 is driven to drive the two sets of licker-in rollers 311 to rotate reversely, and because the two sets of licker-in rollers 311 rotate at different speeds, the licker-in rollers 311 exert tearing force on the plastic bag, so that the garbage in the plastic bag is spilled out.

As shown in fig. 2, the upper part of the treatment tank 3 is flared to facilitate the entry of the waste; and two groups of guide plates 32 which are positioned above the puncturing assembly 31 and are symmetrically arranged are fixed on the inner wall of the collecting box 52, and the opposite ends of the two groups of guide plates 32 are downwards inclined so that garbage can pass through between the two groups of puncturing rollers 311.

As shown in fig. 1 and 2, a rotating rod 33 rotatably connected to the inner wall of the treatment chamber 3, a driving member fixed to the outer wall of the treatment chamber 3, and a plurality of dispersing blades 331 sequentially arranged on the rotating rod 33 along the extending direction of the rotating rod 33 are provided below the puncturing member 31, the driving member is a driving motor 34, and an output shaft of the driving motor 34 is fixedly connected to the rotating rod 33. When the plastic bag is punctured, the driving motor 34 will drive the rotating rod 33 to rotate and cause the dispersing blades 331 to disperse the garbage, so that the residual garbage in the plastic bag is thrown out.

As shown in fig. 2, a first fan 35 and a discharge barrel 36 are arranged below the rotating rod 33, a through groove 38 for fixing and embedding the first fan 35 is formed in the outer wall of the treatment box 3, one end of the discharge barrel 36 is communicated with the treatment box 3 and is opposite to the first fan 35, and a collection bag 39 is mounted at the other end of the discharge barrel 36 through a clamp 37. When the scattering blades throw the garbage in the plastic bags out, the garbage mixed with light matters continuously falls to the first fan 35, and the first fan 35 blows the light matters mixed in the garbage to the collecting bag 39.

As shown in fig. 1 and 3, the output end of the conveyor belt 2 is provided with a touch panel 6, the touch panel 6 is rotatably connected to the frame 1 and abutted against the lower surface of the conveyor belt 2, the touch panel 6 is fixed with a mounting plate 61, the mounting plate 61 is provided with an arc-shaped groove 611, the frame 1 is provided with a bolt 62 threaded out of the arc-shaped groove 611, and the bolt 62 is provided with a nut 63 in a threaded fit manner. The touch panel 6 can rotate and contradict in conveyer belt 2 lower surface for the rubbish sweeps of adhesion are scraped off on the conveyer belt 2, and the cooperation of bolt 62 and nut 63 makes touch panel 6 fixed by locking in frame 1, thereby has guaranteed the stability of touch panel 6.

The implementation principle of the embodiment is as follows: when the garbage is dumped into the treatment tank 3, the two sets of guide plates 32 guide the garbage to between the two sets of licker-in rollers 311; the driving motor 313 drives the two groups of licker-in rollers 311 to rotate reversely, and because the rotating speeds of the two groups of licker-in rollers 311 are different, the licker-in rollers 311 can generate tearing force on the plastic bag, so that the garbage in the plastic bag is spilled; then the driving motor 34 will drive the rotating rod 33 to rotate and make the dispersing blade 331 break up the garbage, and throw out the residual garbage in the plastic bag; the first fan 35 will then blow off the light matter mixed in the waste into the collecting bag 39 and the remaining waste will fall in piles onto the conveyor 2.

In the process of conveying the garbage by the conveyor belt 2, the servo motor 44 drives the screw rod 42 to rotate and drives the scraper 41 to slide along the extending direction of the penetrating rod 43, and the scraper 41 flattens the piled garbage on the conveyor belt 2 in the moving process; when the scraper 41 abuts against the travel switch 45, the travel switch 45 controls the servo motor 44 to rotate reversely, and the servo motor 44 drives the screw rod 42 to rotate reversely and drives the scraper 41 to slide reversely, so that the scraper 41 can make a circulating motion to flatten all the garbage on the conveyor belt 2.

Then the second fan 51 blows the light objects into the transition cylinder 53, and the light objects in the transition cylinder 53 slide into the collection box 52 along the inner wall of the transition cylinder 53, so that the cleaning effect and the cleaning efficiency of the light objects are improved; the garbage and waste chips blown by the second fan 51 on the conveyor belt 2 are blocked by the baffle 54, so that the garbage and waste chips are not easy to blow into the collection box 52; after the garbage is conveyed by the conveyor belt 2, the collision plate 6 scrapes off the garbage scraps adhered to the conveyor belt 2, so as to prevent the garbage scraps from being adhered to the conveyor belt 2 and causing the subsequent garbage to skid when conveyed on the conveyor belt 2.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
