By distinguish using first joint 85 and second joint 91, can select three kinds of exhaust modes, promptly by discharge port 41 exhausts, directly be discharged into the outside of process chamber 7, by above-mentioned two common exhausts of path.Can answer demand and decide.

Process chamber 7 is integrated design with straining chamber 4 in implementing structure.

Below, the food-trash treatment that device for processing food refuse carried out of structure is as mentioned above described:

The food refuse of Chan Shenging with water, throws in input port 11 by cleaning vat 1 within the family.After the food refuse that drops into will be pulverized by comminutor 2, it is imported in this drainage guard by the introducing port 31 of passage 22 with moisture by drainage guard 3, again by the positive rotation of conveyor screw device 5, the spiral upper surface by this conveyor screw device will grind up the refuse and up carry.

In the course of conveying of this whorl 52, pulverize food refuse after moisture is by treatment hole 32 dehydrations, deliver to discharge orifice 33 from the upper end of drainage guard 3.

At this moment, the protuberance 53b of the front-end edge 53a of outstanding insertion plate 53 and the inwall Zhe of drainage guard 3 connect on the front-end edge of whorl 52, so this protuberance 53b can take off grabbing attached to the pulverizing food refuse on drainage guard 3 inwalls, thus, can prevent to pulverize on the inwall of food refuse attached to drainage guard 3, to carry rubbish the obstruction that may cause.So, make to carry respond well, and the obstruction of preventing to grind up the refuse to treatment hole 32.In force, inserting the external end edge concave-convex surface of plate 53, but be not limited in concavo-convexly, for example can also be from the outstanding curve shape of the full edge of external end edge of whorl 52.Whorl 52 external end edges with insert plate 53 and separate, but also whorl 52 front ends and axial region 51 can be made and inserted the parts of the resistance to abrasion stainless steel material of plate 53 one.Under this situation, the whorl inside part just can adopt suitable mode to be connected with the outer end.In addition, also can will insert 53 plates directly are installed in the conveyor screw device in the spiral fashion mode axial region, insert plate 53 by this and form whorl 52.

Grinding up the refuse from the upper end discharge orifice 33 of drainage guard 3 after the dehydration drains into process chamber 7 by chute 71.

Moisture from above-mentioned dewatering hole 32 ejects is discharged into outside the straining chamber 4 by drain hose 42 by discharge port 41.

In drainage guard 3, when pulverizing food refuse and water-recovery, pulverize food refuse in course of conveying, because the factors such as interlock between the front end of the whorl 52 of conveyor screw device and the inwall of drainage guard, make when delivery speed is lower than preset value, can detect the rotation number reduction of the S. A. of carrying motor 58 by inductor 54, thereby indirect detection goes out this state.

Thus,, the conveyor screw device is carried out contrarotation by not shown control setup according to testing result, rotation behind the fixed revolution (for example three change), be rotated in the forward again.If after being rotated in the forward, inductor 54 detects the revolution of carrying motor 58 again to be reduced, and then repeats above-mentioned reverse action again.That is, carry the revolution of motor 58 to recover less than default revolution will carry out the forward retrograde rotation repeatedly when above.Aspect enforcement, carry the revolution of the rotating shaft of motor 58 by inductor 54 detections, this mode detects the delivery speed of the pulverizing food refuse of conveyor screw device 5 indirectly.In fact the detection means of delivery speed more than that.For example, also can detect the load of carrying motor 58 to be born, thereby measure the delivery speed of the pulverizing food refuse that conveyor screw device 5 implemented.In addition, also can directly detect the rotation of conveyor screw device 5.

Thus, rely on the driving of control conveyor screw device, the conveyor screw device is only nibbled between the inwall of pulverizing food refuse and whorl 52 and drainage guard 3 when occurring, and nibbles and reverses for discharging this.Thus, will up carry pulverizing food refuse effectively, and dehydration.

Aforementioned discharge orifice 33 places, grab out of the rotation of the front end 62 of device 6 with conveyor screw device 5, connect by side face Zhe, grab out device 6 and shake in the horizontal direction repeatedly, and grab out the pulverizing food refuse by force to the direction of discharge orifice 33 from the axis part of output screw with cam material 54.Make thus and grind up the refuse to the slick and sly discharge of the foreign side of discharge orifice 33.

At this moment, pulverize food refuse in the process of up carrying, jut 55 that forms by the upper end of conveyor screw device 5 and the setting of the opening fabric width L of discharge orifice 33, fully dehydration, this moisture is separated to the outside of drainage guard 3 from treatment hole 32, and is expelled to process chamber 7 by chute 71 swimmingly from discharge orifice 33.

Thus, can be discharged into process chamber 7 rapidly and swimmingly from discharge orifice 33 with pulverizing food refuse, and rely on first exhaust means 8 described later or second exhaust means 9, again or two sides shared, with the discharges such as foul smell in the process chamber 7, so just do not have the foul smell of pulverizing food refuse around stretch, guarantee comfortable environment.

At this moment, the exterior water that drains into above-mentioned drainage guard 3 can be clarified because of the effect of second partition 45, and covers the upper end of second partition 45, flows to first dividing plate, 44 1 sides.Simultaneously, the foreign material bottom being deposited in flow to first dividing plate, 44 1 sides by the through hole 45a of second partition 45, and the water that overflows with discharge port 41 by the below of this first dividing plate 44 is discharged again.

So, can adjust flowing of ponding in the straining chamber 4, accretion can be flowed into swimmingly discharge port 41 1 sides by second partition 45, simultaneously, on the oil content that floats also can cover second partition, flow into discharge port 41 swimmingly.The inwall that can as far as possible suppress straining chamber 4 thus adheres to and piles up oil content, eliminates and piles up the foul smell that produces and the negative effect of health aspect adhering to of this oil content.

If comminutor 2 is sent to a large amount of pulverizing food refuses and water in the drainage guard 3 together quickly, and so operation continuously, the drainage ability of discharge port does not catch up with, and the water level straight line in the straining chamber 4 rises, and may reach flood stage.

Reach this flood stage, floating 61b can rise with water level and move up.The 61c of flexion portion of pole 61a touching limit switch 62, switch ON then, comminutor stops action.Comminutor stops action, then no longer includes to pulverize in the food refuse importing drainage guard 3, can not increase water level.Thereby, there is water to flow in the drainage guard 3 from comminutor 2, the amount that also can exceed inflow because of the drainage ability of discharge port 41, and pulverizing food refuse also discharges from the discharge orifice of drainage guard 3,4 li water that accumulate of straining chamber also are discharged into the outside gradually by discharge port 41, and the water level in the straining chamber 4 just can drop to normal water level.So the water level abnormality in the straining chamber 4 rises and also can prevent to leak.In addition, oil content sticks on the buoy 61b, does not also influence buoy and moves with fluctuation of water table, can positively detect flood stage, can be strictly on guard against the generation of leaking, and uses the reliability height within the family.

Water level descends, and then limit switch 62 recovers OFF, and comminutor is just got back to the state that can work, can import to drainage guard 3 and pulverize food refuse.

In aforementioned processing chamber 7, anh food grinds up the refuse in treatment trough 72, by mixing device itself and moisture adjustment agent is mixed thoroughly, is adjusted agent at moisture by moisture and absorbs, and adjust moisture.Then, heated by temperature booster 76, air-supply means 8 are toward process chamber 7 interior air supplies again, thereby resolution process is corroded in the promotion fermentation rapidly.Thus, finish the minimizing process of food refuse in the treatment trough 72 of process chamber 7 of pulverizing.

In above-mentioned resolution process process, the foul smell and the moisture that produce in the process chamber 7, in the time of can adopting first joint 85, import the spatial portion 43 of straining chamber 4, be discharged into outside by drain hose 42 with water by discharge port 41 again by exhausr port 81, freeing pipe 82, first joint 85.When adopting second joint 91 of lower ending opening obturation, directly be discharged into the outside of device body.When adopting open second joint 91 of lower ending opening, when being vented to drain hose 42, also directly be discharged into the device body outside by second exhaust pipe 92 from discharge port 41.

At this moment, moisture is adjusted agent and also is dried, and its moisture is discharged into the outside simultaneously, can absorb the moisture that grinds up the refuse that drops into again once more.That is to say that the moisture adjustment agent that storage is stayed in the treatment trough 72 can prolonged and repeatedly be used, and does not need frequent replenishing, thereby significantly reduces operating cost.

After above-mentioned process chamber 7 will be pulverized the food refuse resolution process, handled thing was stayed in the treatment trough 72, and increased gradually, after filling, detect, and stop work of treatment by inspection amount inductor, can open the shutter door that illustrates, the handled thing in the treatment trough 72 is taken out in process chamber 7.Then, emit the broken end of quantitative decomposition, then can carry out the foregoing resolution process that grinds up the refuse.
