Detailed Description

The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings.

When the embodiment is used, organic wastes such as livestock and poultry manure, kitchen waste and the like which need to be treated are conveyed into the tank body 1 through the liquid inlet pipe 2, the liquid position in the tank body 1 can be continuously raised until the liquid to be treated is discharged or the liquid level is detected by the liquid level sensor at the overflow discharge port 3 at the upper end of the tank body 1, at the moment, the liquid level in the tank body 1 is full, the organic wastes cannot be conveyed into the tank body 1 any more, in order to prevent larger particles from blocking the liquid inlet pipe 2 in the liquid discharging process, and meanwhile, the fermentation is incomplete due to the larger particles, so that the organic wastes can be connected to the tank body 1 after preliminary treatment.

After the tank 1 is filled with the liquid to be fermented, the tank is kept stand for a period of time, generally between twenty hours and thirty hours, at this time, the substances in the tank 1 are primarily separated, heavier impurities are deposited in the conical area at the bottom of the tank 1, and the water therein remains on the upper layer of the tank 1, meanwhile, as the tank 1 contains various substances, the substances are separated into the upper layer after deposition, wherein the middle layer is liquid, the upper layer of the liquid floats with the floating substances, the lower layer of the liquid precipitates with the settling substances, and only the liquid in the middle layer needs to be discharged during output to avoid discharging the settling substances at the bottom and the floating substances at the upper layer, so that during discharging, the liquid discharge pipe 4 extends into the tank 1, the hose 7 is connected to the inner part of the tank, the end of the hose 7 is connected with the air bag 8, the air bag 8 always floats on the upper layer of the liquid level under the buoyancy effect, and the connecting part between the hose 7 and the air bag 8 is positioned at the lower end of the air bag 8, and the air bag 8 can be arranged flat, thus the air bag 8 is prevented from turning over under the traction action of the hose 7, and the water of the heavy object 8 should be provided with the lower end of the air bag 8 to be prevented from flowing to the upper layer through the opening of the hose.

The water in the upper layer of the tank body 1 is discharged firstly, the liquid discharge pipe 4 is opened, the water in the tank body 1 is pumped out through the liquid discharge pipe 4, the water level in the tank body 1 continuously descends, the floating object at the upper end of the tank body 1 gradually descends, the sediment at the lower end of the tank body 1 is always positioned at a position with the downward liquid level top end at a certain position, the sediment at the bottom is not disturbed, the air bag 8 gradually descends in the liquid level descending process, the end part of the hose 7 is changed along with the height of the air bag 8, in order to prevent the hose 7 from descending in the descending process, thereby disturbing the sediment, the middle part of the hose 7 is connected to the tank body 1 through the buckle 10, in the downward movement process of the end part of the hose 7, the maximum downward movement stroke of the end part of the hose 7 does not affect the sediment, namely the sediment is not discharged, the lower water outlet position can well utilize the atmospheric pressure to discharge the liquid, the liquid discharge pipe 4 is closed until the middle layer liquid in the tank body 1 is discharged, the sediment and the floating matters are remained in the tank body 1 and a certain amount of liquid which is not discharged at the moment, the discharge port 5 positioned at the lower end of the tank body 1 is opened to discharge the residual material, the material can be pumped out by the discharge port 5 through a certain pumping force and then conveyed to the solid-liquid separator 11, the solid-liquid separator 11 is in the prior art, the solid-liquid separation is carried out on the material through the solid-liquid separator 11, at the moment, the total amount and the water content of the solid-liquid separation are reduced, so that a great amount of energy loss can be reduced, and simultaneously, the efficiency is improved.

In the process of discharging the residual materials, a small amount of liquid can be conveyed into the tank body 1 through the liquid inlet pipe 2 to flush the residual materials on the inner side wall of the tank body 1.

The middle pipe vertically arranged in the tank body 1 is positioned at the middle part inside the tank body 1, the dispersing pieces 9 are arranged at the lower end of the middle pipe, the material is blocked by the dispersing pieces 9 to be divergent in the downward conveying process through the middle pipe, and then the inner side surface of the tank body 1 is flushed, so that the residual material flows downwards instead of being adhered to the tank body 1.

And the overflow discharge port 3 positioned on the side surface of the upper end of the tank body 1 plays the roles of detecting the height of the liquid level in the tank body 1 and preventing the liquid level from overflowing, and the hose and the middle pipe are staggered to prevent blocking.
