2. The welding position adopts seamless welding.

3. The paint is black asphalt paint.

4. The excrement leaking plate is completely spliced, and the part which is tightly contacted with the box body is only left about 3 mm.

5. The length and width of the high elastic cotton are about 1 to 2 centimeters larger than that of the box body, so that vacuum can be formed quickly and effectively. High loft cotton requires a custom made monolith to ensure efficient formation of the vacuum.

6. The bricks used in the water storage layer are preferably fired red bricks which are not afraid of the erosion of turbid water.

7. In order to prevent explosion, a water outlet valve is opened in the process of separating wet and dilute water by gravity.

8. In order to prevent the possibility of the explosion gas causing excessive killing power, a square steel is preferably welded in the center of the upper opening of the box body.

The utility model discloses a theory of operation does:

generally, the pigsty is cleaned once a day, and during cleaning, thin manure is collected in a pipeline and flows into a pig manure separator. And (3) opening a water outlet valve (if the water outlet valve is not opened, turbid water is fermented in the water storage layer, gas is released, and when the pressure is overlarge to a certain degree, a certain side of the peripheral side gap is instantly flushed, so that the excrement leaking layer can be lifted and turned over to form explosion). And after the separation of the dilute wet water by gravity is finished, closing the water outlet valve, opening the vacuum valve and starting the separation of the wet dry water by negative pressure. After separation, the vacuum valve is closed, the water outlet valve is opened, and the water storage layer is emptied. In a large pig farm, when the amount of dilute liquid dung exceeds 5 tons every day, two pig manure separators are arranged and used in turn to ensure that fresh dilute manure is changed into dry manure and turbid water in time.

The pig manure separator is used for separating pig manure from water, the pig manure is firstly flowed into the pig manure separator, the pig manure is flowed onto the high-layer manure-leaking plate, under the action of gravity the water content in the pig manure is filtered by the high-layer manure-leaking plate, high-elastic cotton and bottom manure-leaking plate, and is reached to water storage layer, and then is flowed into first-stage sedimentation tank by means of water outlet valve. Negative pressure wet-dry water separation: after a period of time, the thin manure becomes wet manure, and the gravity can not make the moisture in the wet manure flow out quickly. At this point, the vacuum valve assembly is opened and the outlet valve is closed. Under the powerful action of vacuum negative pressure, moisture in the wet manure is quickly separated to a water storage layer, and the moisture flows to a primary sedimentation tank after vacuumizing is finished. The wet manure becomes dry manure. The dry manure is shoveled away by a shovel and is returned to the field for use. The separated water was not clear water, but the turbidity was very low. And fermenting and precipitating the turbid water in the primary sedimentation tank for a period of time, pumping the turbid water into the secondary sedimentation tank, adding bleaching powder or caustic soda into the secondary sedimentation tank to obtain clear water, pumping the clear water into the tertiary sedimentation tank, and storing the clear water for cleaning the pig farm or spraying vegetation around the pig farm.
