The invention relates to the technical field of environmental protection equipment, in particular to a livestock and poultry manure treatment machine with high water content.
Background
Livestock manure is an important fertilizer resource for agricultural production, and in order to respond to environmental protection production calls in recent years, the livestock manure tends to be processed in a flow way and environmental protection after collection. At present, the adopted treatment modes mainly comprise: the livestock manure is collected in the manure pit by a farmer through flushing livestock manure with water, after the livestock manure is collected to a certain volume, the collected livestock manure is subjected to extrusion dehydration treatment by adopting solid-liquid separation equipment, the dehydration rate of the dehydrated manure can reach about 50%, the dehydrated manure is abbreviated as dehydrated manure, the dehydrated manure has no odor, the main components are undigested feed fibers and the like, the undigested feed fibers can be used as feed after further fermentation treatment, and the extrusion filtered manure can enter a methane tank for fermentation treatment, so that the fermentation time can be shortened due to fewer impurities, and a better fermentation effect can be achieved.
The application date is 2017.09.18 among the prior art, the authority bulletin number is CN207175750U discloses a fresh livestock manure solid-liquid separation machine, see FIG. 9, including base, casing, motor, support frame, speed reducer, transmission shaft, filter screen, pressure regulating device, the filter screen is located outside the casing, and the transmission shaft is encircleed outward and is had helical blade, and the left end of casing is equipped with the feed inlet, and the right-hand member is equipped with the discharge gate, and pressure regulating device locates discharge gate department for the moisture content of control dehydration manure, and this equipment theory of operation is: the fresh wet livestock manure is pumped to a feed inlet of a solid-liquid separator by a sludge pump, the feed is pushed forward by a screw extrusion mechanism of the solid-liquid separator, the material moves forward along a filter screen, the liquid passes through the filter screen under the pressure action of a screw blade and falls to a bottom liquid outlet of the solid-liquid separator, the liquid is conveyed to a feed liquid storage tank by a pipeline, and the dehydrated solid material is screwed out from the feed outlet; in the material extrusion process, as the screw extrusion mechanism continuously extrudes the material towards the discharge end, in order to reduce the water content of the material, the opening pressure of the pressure regulating device is generally increased, so that the material is continuously extruded on one side of the discharge end, and the water is discharged through the filter mesh screen, thereby achieving the purpose of reducing the water content.
The extrusion filtering discharging principle of the horizontal type screw extrusion mechanism in the prior art is mainly realized by virtue of the extrusion force built in the interior, if livestock and poultry manure with general water content enters the interior, the extrusion effect can be quickly and well achieved, but for water-washed manure with higher water content, the solid components contained in the manure are very small compared with the common manure, when the manure is subjected to solid-liquid treatment through the common horizontal type solid-liquid separator, the solid components are very small, the solid materials are difficult to be quickly gathered and extruded in the screw extrusion mechanism, so that the extrusion force in the screw extrusion mechanism is difficult to build, and when the manure does not reach the required discharging dryness, the discharge hole is opened by the impact of the manure with higher humidity, so that the good solid-liquid separation effect cannot be achieved.
Therefore, the horizontal screw extrusion mechanism in the prior art is mainly applied to livestock manure with general water content, thereby achieving the purpose of reducing the water content, the opening pressure arranged at the discharge end needs to be larger, but the pressure applied to the surface of the filter screen is also very high, the filter screen with 0.8mm-1mm is generally selected to avoid extrusion damage, if the filter screen with 0.4mm-0.5mm is selected, the screen holes are smaller, the particles in the materials are larger, the filtering capacity of the screen holes is limited, the condition that the screen holes are blocked exists, the pressure of the discharge port can be increased rapidly, part of the water in the materials is not discharged through the screen holes, the discharge port is extruded and opened, and if the opening pressure is increased, the extrusion force on the surface of the filter screen is very high, the screen is easy to damage, therefore, the screen with 0.8mm-1mm or larger screen holes is generally adopted in the industry, the manure water after extrusion is sticky, contains a large amount of non-separated solid matters, and the separation effect is not optimal.
