Dairy cow dung dehydration extruder

Abstract

The invention discloses a dairy cow dung dehydration extruder which comprises a rack, a feeding port, a discharging port, an extruding device, a pressure device and a first driving device. The extruding device is used for conveying dung from the feeding port to the discharging port and extruding and drying the dung. The extruding device comprises an extruding bin, a transmission roller and mincingblades. A plurality of filtering devices are arranged at the bottom of the extruding bin, the pressure device is installed at the rear end of the rack in a sliding mode, and the first driving deviceis used for driving the transmission roller to rotate. The extruding device and the pressure device are arranged on the rack, the dung is transported through the extruding device and pressure appliedto the position of the discharging port is applied; meanwhile, the extruding bin is sealed through the pressure device, thrust opposite to the extruding device is applied to the dung located at the position of the discharging port, the dung is dried through extrusion; meanwhile, the dung can be fluffy through stirring of the twisted blades, and the dehydration effect is further improved. The dungis extruded and stirred so that the dung is more convenient to use and store.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a milk cow dung dehydration extrusion machine. Background technique [0002] One-quarter of feces is water, and the rest is mostly protein, inorganic matter, fat, undigested dietary fiber, dehydrated digestive juice residue, cells and dead bacteria shed from the intestinal tract, and vitamin K , Vitamin B. Dairy farm manure is backfilled in bed after dehydration treatment, which can realize the reuse of waste and replace the original use of rice husk and other materials as bedding, saving farm expenses. [0003] The existing feces treatment process is generally as follows: 1. Solid-liquid separation: preliminary dehydration of the feces. At this time, the water content of the feces is about 15%, and the solid shape is basically realized; 2. Drying: through a heating dryer or a solid-liquid separator for feces Further dehydration treatment, the water content is about 10...
