Problems solved by technology

[0003] The technical problem of this method of pig manure treatment is: the manure tank is connected to the outside world, and there is more water in the manure tank, because the manure tank is likely to receive rainwater or seepage from the outside, and the effective solid manure will disperse when it enters the manure tank , use the feces delivery pump to beat continuously, the transported mixture has high water content, and the livestock manure

Embodiment 1

[0025] Such as figure 1 As shown, the environment-friendly pig raising method described in this embodiment adopts a pig house 1 and a biogas digester 3 in a pig farm. The feature is that the pig manure produced during the breeding process is first collected in the manure tank 106, from The excrement discharged from the manure tank 106 enters the centrifugal pre-separation device 2. In the centrifugal pre-separation device 2, part of the manure water is separated and discharged into the biogas tank 3, and the excrement discharged from the centrifugal pre-separation device 2 enters The livestock manure solid-liquid separator 4 performs separation, and the manure water discharged from the overflow port 42 and the liquid outlet 43 of the livestock manure solid-liquid separator 4 is discharged into the biogas digester 3, and from the solid outlet of the livestock manure solid-liquid separator 4 44 The solid feces discharged are used for sale.

[0026] Specifically: such as Figure 4 w...

Embodiment 2

[0039] The environment-friendly pig raising method described in this embodiment differs from embodiment 1 in that a liquid level switch is provided on the overflow port 42 of the livestock manure solid-liquid separator 4, and when the liquid level switch detects When it overflows, stop the extrusion motor 113 and the centrifugal separation motor 212,

[0040] Or instead of stopping the motor, the extrusion motor 113 and the centrifugal separation motor 212 are decelerated to operate.

[0041] When the squeezing motor 113 stops or decelerates, the excrement tank 106 is discharged into the centrifugal pre-separation device 2 to stop or slow down

[0042] When the centrifugal separation motor 212 stops or decelerates, the centrifugal pre-separation device 2 will stop or decelerate.

[0043] In this way, when the livestock manure solid-liquid separator 4 cannot handle the overflow, the two devices above the manure tank 106 and the centrifugal separation motor 212 are stopped or decelerate...

Abstract

The invention discloses an environment-friendly pig raising method. A pig house and a biogas digester are arranged in a pig farm; the pig raising method is characterized in that pig manure generated in the breeding process is collected in a manure tank first, manure pumped out of the manure tank enters a centrifugal pre-separating device, part of liquid manure is separated from the centrifugal pre-separating device and drained into the biogas digester, liquid manure drained from an overflow opening and a liquid outlet of a livestock manure solid-liquid separator is drained into the biogas digester, and solid manure discharged from a solid outlet of the livestock manure solid-liquid separator is used for sale. According to the pig manure processing method, a traditional liquid manure pond is not arranged, the liquid manure out of the pig house is directly separated through the centrifugal pre-separating device and the livestock manure solid-liquid separator, and the solid pig manure can be separated more efficiently and fast; income can be created for the pig farm, the environment is protected, and therefore double purposes are achieved through one effort.

Description

Technical field [0001] The invention relates to a pig raising method, in particular to an environmentally friendly pig raising method. Background technique [0002] Pig manure treatment is an important part of pig farms. The existing pig manure treatment methods of pig farms are as follows: manure is manually discharged into the manure tank, and the manure water in the manure tank is pumped into the animal manure solid by the manure transfer pump. The liquid separator performs solid-liquid separation. The existing livestock manure solid-liquid separator has a feed port, an overflow port, a liquid outlet and a solid outlet. The manure water is separated from the solid manure through the feed port. It is discharged from the solid outlet and can be collected and sold. The treated manure water is discharged from the liquid outlet into the biogas tank for fermentation to produce biogas. The biogas can also be sold; the manure water that is too late for treatment is discharged from th...
