Example 1

Referring to fig. 1, the present embodiment provides a wet waste preliminary processor, which includes a housing 1, a screw shaft and a driving member 11 for driving the screw shaft to rotate; the screw shaft is arranged in the shell 1 and comprises a crushing section 2 and an extrusion section 3; the shell 1 is provided with a feed inlet 101 at the crushing section 2 and a discharge outlet 102 at the extrusion section 3.

Wet garbage enters the shell 1 from the feeding hole 101, is firstly crushed in the crushing section 2 to reduce the volume, then enters the extrusion section 3 to be extruded to further reduce the volume, and finally comes out from the discharging hole 102.

The structure of the present embodiment will now be explained.

The shell 1 is a cylinder coaxial with the screw shaft, and the screw blade on the screw shaft is divided into a crushing section 2 and an extrusion section 3; and the distance between the outside of the helical blade and the housing 1 is extremely small. The shell 1 has two ends, a first end corresponding to the crushing section 2 and a second end corresponding to the squeezing section 3. The inlet 101 is arranged at the upper side of the first end of the housing 1 and the outlet 102 is arranged at the lower side of the second end of the housing 1. Wet garbage to be treated enters the shell 1 from the feeding hole 101, passes through the crushing section 2 and the extrusion section 3 and then is discharged from the discharging hole 102. The crushing section 2 adopts a first helical blade which is arranged discontinuously, and can be a disconnected wear-resistant steel sheet, so that large wet garbage is crushed, and the volume of the wet garbage is reduced. Extrusion section 3 adopts the second helical blade of displacement step by step, specifically can adopt the continuous steel sheet of displacement step by step, is pushing the in-process that wet rubbish impels step by step, receives the extrusion volume to diminish, simultaneously because the feed volume reduces gradually, can extrude the waste liquid in the wet rubbish.

The shell 1 is obliquely arranged, the vertical height of a first end of the shell 1 is lower than that of a second end, and a water outlet 103 is formed in the lower side surface of the first end. The waste liquid squeezed from the wet waste flows back to the first end of the housing 1 and out of the outlet 103. And a filter screen is arranged at the water outlet 103 to prevent the solid in the wet garbage from flowing out from the water blowing port. A waste liquid collecting box 7 is arranged below the water outlet 103, and a first opening corresponding to the water outlet 103 is arranged on the waste liquid collecting box 7. The first opening is communicated with the water outlet 103, and waste liquid enters the waste liquid collecting box 7 from the water outlet 103.

Further, set up the third opening on the lateral wall of waste liquid collecting box 7, set up waste oil collecting box 8 by waste liquid collecting box 7, set up the fourth opening on waste oil collecting box 8, fourth opening and third opening intercommunication, and the lower extreme of fourth opening is less than the lower extreme of third opening. The waste water outlet 9 is arranged at the bottom of the waste liquid collecting box 7, and the waste oil outlet 10 is arranged at the bottom of the waste liquid collecting box 8. The waste water outlet 9 is closed, waste liquid generated by wet garbage is slowly accumulated in the waste liquid collecting box 7, the liquid level is gradually increased, and the waste oil can float above the waste water due to the specific gravity characteristic of oil and water in the waste liquid; the liquid level of the waste liquid is increased and reaches the third opening, and the waste oil above the waste liquid enters the waste oil collecting box 8 through the third opening and the fourth opening. When the waste water in the waste liquid is high to reach the third opening, the waste water outlet 9 is opened, a part of the waste water is discharged, and then the waste water outlet 9 is closed. When the liquid level of the waste oil in the waste oil collecting box 8 is about to reach the fourth opening, the waste oil outlet 10 is opened, part or all of the waste oil is discharged, and then the waste oil outlet 10 is closed; or the waste oil outlet 10 is always opened. A screen may be provided at the third opening and/or the fourth opening. The waste oil collecting box 8 and the related arrangement thereof can utilize the specific gravity characteristic of oil and water in the waste liquid, and can primarily separate and then collect the waste water and the waste oil in the waste liquid.

In this embodiment, a feeding hopper 5 is arranged above the feeding port 101, and the feeding hopper 5 is communicated with the feeding port 101 for conveniently dumping wet garbage into the casing 1. The dry material collecting box 6 is arranged below the discharge port 102, a second opening corresponding to the discharge port 102 is arranged on the dry material collecting box 6, and the second opening is positioned under the discharge port 102. The dry material collection box 6 is used for collecting the wet garbage after primary treatment.

Further, a discharge end baffle 4 is arranged on the spiral shaft. One end of the extrusion section 3 is connected with the crushing section 2, and the other end is connected with the discharge end baffle 4; in other embodiments, there may be no direct connection between the crushing section 2 and the pressing section 3, but the distance between the two must not be too great, which would make the wet waste lack sufficient power to enter the pressing section 3. Discharge end baffle 4 is located discharge gate 102 directly over, can ensure that moisturizing rubbish can go out from discharge gate 102 smoothly after final extrusion.

Specifically, in the present embodiment, a first end of the screw shaft is connected to the head shaft 12 through the head bearing 13, and a second end of the screw shaft is connected to the tail shaft 15 through the tail bearing 14. The driving member 11 is connected to the head shaft 12 for driving the head shaft 12 to rotate, thereby rotating the screw shaft. The drive 11 may in particular be an electric motor.
