Description

[0001] The present application relates to the technical field of cattle manure treatment equipment, in particular to the technical field of a horizontal cattle manure solid-liquid separator.

[0002] With the rapid development of cattle industry, manure pollution has become a big problem. Due to insufficient attention to the treatment of cattle manure in some areas, cattle manure is randomly stacked and placed in some places where cattle are raised, and in summer, the stench is overwhelming, which not only affects the normal life of the surrounding residents, but also is the source of the breeding of a variety of bacterial pathogens, which has a serious impact on the breeding group. Large-scale cattle farms produce a lot of cattle manure, which will affect the environment and the health of livestock if not properly treated in time. Cattle manure can be used as fuel or to produce organic fertilizer, but these all need to be dehydrated first to facilitate the storage and transportation of cattle manure. If it is naturally dried, it not only needs a long time and a large space, but also causes air pollution and affects the environment around the farm. Most of the existing cattle manure treatment devices use a spiral extrusion method for solid-liquid separation. Since the solid content of cattle manure is only about 15%, the spiral extrusion method cannot well solve the problem of the water content of the solid after separation. The water content of the solid after spiral extrusion is 65%-75%, which increases the energy consumption of the later cattle manure drying operation.

[0003] The purpose of the present application is to solve the problems in the prior art and provide a horizontal cattle manure solid-liquid separator, which can drive the pressing plate to press the cattle manure into the cylinder body of the press through the oil cylinder of the horizontal press to separate the solid and liquid, and can also discharge the cattle manure solid through the head end cover. The water content of the cattle manure solid can be as low as 45%, which is beneficial to reduce the energy consumption of the later cattle manure drying operation.
