Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
Changing food waste sorting pulping device provided by the invention, adopts the method for physical sepn, and its theoretical foundation is: in rubbish, organic matter is different with whether non-organic matter can be made into slurry ability after pulverizing under high speed impact and pulverizing. Under normal circumstances, most organic matter all can be pulverized under high speed impact, by means of self or the appropriate water yield added, it is possible to form slurry, thus discharged by slurry delivery pipe; And the non-organic matter not easily pulverized such as plastics, metal etc., even if part is pulverized, also can not form slurry, therefore still not by liquid outlet opening, and can only be discharged by the discharge port at top. Therefore, through changing food waste sorting pulping device, the organic matter in rubbish and non-organic matter can be discharged by different discharge ports, reach the effect of the organic matter of separation and non-organic matter.
Concrete, composition graphs 1 and Fig. 2, the present invention provides a kind of changing food waste sorting pulping device, comprises housing 3, and the inside of housing 3 is provided with screen drum, and the barrel at screen drum arranges multiple sieve aperture, and the aperture of sieve aperture is preferably 10-30mm. The axle center of the inside of screen drum is provided with rotating shaft, and linking with the drive unit 5 being positioned at housing 3 outside through the top of screen drum near the diapire of screen drum, the top of this rotating shaft in the bottom of this rotating shaft, drive unit 5 can adopt motor. Under the effect of drive unit 5, rotating shaft is driven to rotate; Rotating shaft from top to bottom Spiral distribution have multiple parallel blade, each blade is inclined upwardly, and concrete angle of inclination adjusts according to the feature of actual process and processed changing food waste, under normal circumstances, can be set to 5-12 °.
Sidewall at housing 3 is provided with opening for feed 4; The slurry receiving tank 7 being connected with screen drum it is provided with in the lower section of housing 3; Slurry receiving tank 7 is configured with slurry delivery pipe 1; In addition, also comprising mashing pump 8, the opening for feed of this mashing pump 8 is connected with slurry receiving tank 7, and the discharge port of this mashing pump 8 is connected with slurry delivery pipe 1; The discharge port 2 being connected with screen drum it is provided with on the top of housing 3.
In addition, slurry receiving tank 7 is also provided with water-in 9. Housing 3 is also provided with and observes clean-up port 6. According to technique water ratio needs, by water-in 9, meal kitchen slurry is added water, and there is the effect of equipment washing simultaneously. There are blocking or other unforeseen circumstancess when equipment under, carry out maintenance of clean-up by opening observation clean-up port 6.
The principle of work of said apparatus can roughly be described as:
Entering the changing food waste of screen drum inside, be separated by following process implementation: arrange the screen drum that circumference is covered with sieve aperture in closed housing, screen drum inside arranges the main shaft of band blade, and blade has cutting and forms the dual function of air-flow. Treated object is cut by blade and screen drum comprehensive action in screen drum, can be cut material, and namely organic matter is flowed into slurry receiving tank by slurry by sieve aperture; And the free of non-organic species that can not be cut, such as the thing such as plastics and metal, then discharge by the discharge port on screen drum top.
Above-mentioned changing food waste sorting pulping device has following innovative design:
(1) arrange the screen drum being covered with sieve aperture in closed enclosure interior, screen drum inside arranges the rotating shaft of band blade; Blade has cutting and forms air-flow dual function, thus the effect that organic matter is separated by realization with non-organic matter;
(2) mashing pump passes through liquid level switch, it is possible to realize the chain control with feeding unit.
(3) housing has inner cleaning function, can realize by water pipe is connected to water-in.
The present invention also provides a kind of changing food waste sorting pulping process, comprises the following steps:
S1, starts drive unit 5, and then drives the rotating shaft being positioned at screen drum inside to rotate, thus drives the blade rotary being fixed on rotating shaft;
S2, when processed changing food waste enters into screen drum inside by opening for feed 4, the blade of screen drum internal rotating and the barrel of screen drum comprehensively cut processed changing food waste, for the organic matter in changing food waste, by the cutting action of blade and screen drum and slurry, the slurry obtained is flowed into the slurry receiving tank 7 being arranged in below screen drum by the sieve aperture of screen drum; And non-organic matter dihedral vane hit beat and air-flow dual function under, rise along inboard wall of riddle drum and discharged by discharge port 2, and then realize the sorting pulping process of organic matter and non-organic matter in changing food waste.
Further, non-organic matter is by the material of blade and screen drum cutting, cannot can divide into two class non-organic matter, be respectively: first kind non-organic matter and the 2nd class non-organic matter; First kind non-organic matter refers to that density is greater than 1.0g/cm3Material; 2nd class non-organic matter refers to that density is less than 1.0g/cm3Material;
First kind non-organic matter blade continuously upwards hit the effect of beating under, discharge by the discharge port 2 on screen drum top; Under the airflow function that 2nd class non-organic matter produces at rotating paddle, discharge by the discharge port 2 on screen drum top.
Also comprise:
S3, the slurry being flowed in slurry receiving tank 7 is discharged to the outside by mashing pump 8 by slurry delivery pipe 1.
Changing food waste slurry water ratio about 90%, complicated component, wherein containing plastics, the bone even material such as metal. And changing food waste sorting pulping equipment provided by the invention, it is specially changing food waste is developed, changing food waste can be carried out efficient sorting and slurrying, the efficiency of separation is up to more than 95%, thus by organic matter and the non-organic matter high efficiency separation such as plastics, metal, the slurry made can directly carry out fermentative processing, it is achieved recycling; And the non-organic matter recoverables such as the plastics sub-elected, metal. Therefore, be conducive to the classification of rubbish to process, it is achieved that the recycling of rubbish.
The above is only the preferred embodiment of the present invention; it is noted that for those skilled in the art, under the premise without departing from the principles of the invention; can also making some improvements and modifications, these improvements and modifications also should look protection scope of the present invention.
