NOVELTY - Liquid fertilizer manufacturing device comprises a water collecting tank for collecting water and manure transported from multiple transportation units, a solid-liquid separator for separating solid and liquid type manure accommodated in the water collecting tank, a liquefied fertilizer producing module for converting the separated liquid type manure into liquefied fertilizer by accommodating processed water and is coupled to the solid-liquid separator, and a liquefied fertilizer storing module for accommodating the liquefied fertilizer produced by the liquefied fertilizer producing module.    USE - Used as a liquid fertilizer manufacturing device.    ADVANTAGE - The device produces liquefied fertilizer in a short period of time by forcibly increasing the fermentation rate of the processed water, simultaneously supplies oxygen or air and circulates the processed water accommodated in the reaction tank, increases the amount of oxygen dissolved in the processed water and retention time of the bubbles, and removes sludge deposited at the bottom surface by injecting washing water.    DETAILED DESCRIPTION - Liquid fertilizer manufacturing device comprises a water collecting tank for collecting water and manure transported from multiple transportation units, a solid-liquid separator for separating solid and liquid type manure accommodated in the water collecting tank, a liquefied fertilizer producing module (300) for converting the separated liquid type manure into liquefied fertilizer by accommodating processed water and is coupled to the solid-liquid separator, and a liquefied fertilizer storing module for accommodating the liquefied fertilizer produced by the liquefied fertilizer producing module. The liquefied fertilizer producing module comprises a reaction tank (310) formed with an accommodating space (312) for accommodating the processed water inside and is provided with an inlet port (314) for flowing the processed water and a discharge port (316) at the lower part for discharging the processed water, a suction chamber arranged along the vertical direction from the upper portion of the reaction tank for inhaling the processed water accommodated in the reaction tank by uniform pressure and is equipped with multiple communicating ports, a processed water circulating unit for circulating the processed water accommodated in the reaction tank and is provided with a venturi for expanding, a processed water circulating pipe placed at the upper portion of the reaction tank for circulating the processed water towards the lower part of the reaction tank by inhaling the processed water and communicating with one side of the suction chamber, a pressure shaft for circulating the processed water and decreasing and increasing the diameter of a circulating path of the processed water circulating pipe, an air circulating unit sucking air generated within the reaction tank and is connected to the upper portion of the reaction tank, oxygen supplying unit connected to separate source of oxygen for moving oxygen, an air chamber for supplying oxygen or air to the processed water and circulating oxygen or air to the processed water circulating pipe and communicating with the venturi, the oxygen supplying unit and the air circulating unit, an air supplying unit for supplying oxygen or air for performing fermentation of the processed water and circulating the processed water by the processed water circulating unit, multiple unit members elongatedly formed with a plate-shaped first side and a second side having slopes in different directions, a fixing unit for fixing the unit members and maintaining the mutual coupling state and intersecting with the multiple unit members along the longitudinal direction, a mixed flow unit for dissolving the processed water by increasing the retention time through interfering with the rising of the air or oxygen particles and is inclinedly arranged along the vertical direction of the reaction tank, a suction pipe for sucking the processed water from inside the reaction tank, a processed water injecting unit for injecting the processed water sucked through the suction pipe and is placed spaced apart from form multiple injection hole and communicating with the other side of the suction pipe, and a bubble removing unit for removing bubbles generated from the processed water and spraying the processed water from top to bottom by sucking the processed water accommodated in the reaction tank. The liquefied fertilizer storing module comprises a storage tank equipped with a bottom surface having predetermined inclined angle for accommodating the liquefied fertilizer produced from the liquefied fertilizer producing module, a rotary screw formed with a screw thread on the outer surface and is arranged adjacent to the uppermost portion of the bottom surface and is rotatably coupled along the vertical direction of the storage tank, an elevating member for adjusting the position of the storage tank along the vertical direction according to the rotation state of the rotary screw, and a cleaning unit provided with a high-pressure injection portion for injecting high-pressure washing water at the bottom surface and supplying separate washing water from outside and is coupled to the elevating member.
