NOVELTY - A multi-functional efficient livestock and poultry excrement treatment device comprises an excrement fermenting box and an outer circumference heat insulating and light-passing board set on the fermenting box; where a hollow annular heater is mounted in the excrement fermenting box; the exterior of the heater is excrement; the heater is connected with a solar heat collector through pipes; the fermenting box is equipped with an excrement feet port; and the bottom of the fermenting box is equipped with a spiral extruding, dehydrating and crushing discharge device.    USE - The multi-functional efficient livestock and poultry excrement treatment device is useful for industrial and commercial applications.    ADVANTAGE - The multi-functional efficient livestock and poultry excrement treatment device makes full use of solar energy as heat source, with rapid heat increasing, good heat insulating, and automatic feeding; where it can be used for a long time. Moreover, it can fully erode excrement, kill harmful materials, and generate useful bacterium and methane. Additionally, the methane dregs and liquid can be transported immediately, which meets the national requirements pollutant emission.    DETAILED DESCRIPTION - A multi-functional efficient livestock and poultry excrement treatment device comprises an excrement fermenting box and an outer circumference heat insulating and light-passing board set on the fermenting box; where a hollow annular heater is mounted in the excrement fermenting box; the exterior of the heater is excrement; the heater is connected with a solar heat collector through pipes; the fermenting box is equipped with an excrement feet port, connected to an excrement conveying pump through a conveying pipe, which is equipped with an electromagnetic valve; the bottom of the fermenting box is equipped with a spiral extruding, dehydrating and crushing discharge device; and the tail end of the spiral extruding device is the discharge port of the fermenting box.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the multi-functional efficient livestock and poultry excrement treatment device.
