The disadvantages are as follows: the capacity is small, the continuous operation is difficult, the large-scale industrial applicability is poor, the later maintenance cost of the device is extremely high, the recovery of very small particle solid matters is difficult, and the equipment investment is high.
(2) Inclined screen type solid-liquid separator: the pig manure water is gradually pushed to the front of the machine by the auger, and meanwhile, the pressure of the front edge of the machine is continuously increased, so that the moisture in the material is forced to extrude out of the mesh screen under the action of the side pressing and filtering, and flows out of the drain pipe. The inclined screen type solid-liquid separator works continuously, pig manure water is lifted into the pig manure dewatering machine body continuously, the pressure of the front edge is increased continuously, and when the pressure is high to a certain degree, the discharge hole is pushed open and is extruded out of the extrusion hole, so that the purpose of extruding and discharging is achieved.
The disadvantages are as follows: the full open type structural design easily causes secondary pollution, does not accord with the requirement of specific production, and the vibration separation is noisy, the easy loss.
(3) A vertical solid-liquid separator: according to the principle of gravimetry, liquid flows downwards under the action of gravity from the upper part, solid-liquid separation is realized by utilizing a multi-layer filter screen, but because the filter screen is horizontally placed according to the flow direction of water, solid waste attached to the surface is not easy to remove, and generally the device also needs to be matched with other devices to be efficiently and continuously used.
