Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a compost tea production equipment, specifically the utility model relates to an improved equipment for producing compost tea, which can continuously wash compost materials by circulating water until the desired compost tea concentration is reached, and then directly spray the produced compost tea on the ground to enhance soil fertility. BACKGROUND
[0002] Compost tea is a compost liquid obtained by fully soaking compost in water and adding oxygen. Compared with compost mixed into the soil, compost tea has better effects on plants.
[0003] Compost tea can be directly applied to the soil or sprayed on the leaves. When applied to the soil, compost tea can penetrate the soil and directly enter the root zone, affecting the plant's rhizosphere. The nutrients in compost tea are utilized by plants and microorganisms. The microorganisms in compost tea enter the soil and compete with soil microorganisms, eventually becoming part of the soil and rhizosphere ecology. Compost tea applied directly to the soil does not need to be filtered before application, thus retaining more microorganisms and providing greater microbial quantity and diversity than leaf spraying.
[0004] Current compost tea equipment designed by many families has the problems of uncontrollable microbial concentration of produced compost tea and inconvenience of use. The equipment described in this paper is improved based on existing equipment. The equipment can wash the compost to make nutrients and microorganisms dissolve in the washing water, and the washing water is recycled until the desired compost concentration is reached. SUMMARY
[0005] The utility model relates to a kind of compost tea production equipment of circular washing, including the hopper of compost material into equipment in it. The bottom of hopper is inclined, first screw conveyor is installed at the bottom of hopper, the first screw conveyor is sent compost material towards its lower end and enters discharge pipe. Anti-clogging screw conveyor is located in the compost hopper above first screw conveyor, to prevent compost material from being blocked in hopper. Compost material is discharged downward from the lower end of hopper to the lower end of upwardly inclined separator housing by discharge pipe, second screw conveyor is rotatably installed in the separator housing, for compost material is sent from the lower end of separator housing to the upper end of separator housing. Second screw conveyor includes hollow screw shaft, and a plurality of drainage nozzles are installed on the screw shaft. Separator housing has cylindrical screen around second screw conveyor, to prevent compost material from entering separator. Separator tank is located below separator housing and is in fluid communication therewith, for containing washing water containing microorganisms in compost.
[0006] The apparatus also includes a water tank having a first water conduit extending from a water tank drain to an inlet side of the pump. A second water conduit extends from a discharge side of the pump to an inlet side of the filter. A third water conduit extends from a first filter outlet to a screw shaft of the second screw conveyor to supply water to the discharge nozzle. A fourth water conduit extends from the second water conduit to a compost tea jar for receiving finished compost tea. A stop valve is installed in the fourth water conduit for controlling discharge of the finished compost tea. A fifth water conduit extends from a lower end of the separator jar to the first water conduit.
[0007] Water is supplied through the third water conduit to the screw shaft in the separator housing to spray water from the discharge nozzle on the screw shaft onto the compost material passing through the separator housing to cause the microorganisms on the compost material to be flushed into the wash water. The washed wash water is collected in the separator jar and recirculated to the first water conduit. The spent compost material is discharged from the separator housing to a spent compost material pile. The compost tea is recirculated through the apparatus until the compost tea reaches a desired concentration. When the concentration of the compost tea in the separator jar reaches the desired concentration, the stop valve is opened to discharge the compost tea through the fourth water conduit to a designated compost tea jar.
[0008] Accordingly, it is a primary object of the present invention to provide an improved apparatus for producing compost tea that flushes microorganisms from the compost with water and recirculates the compost tea through the apparatus until a proper concentration of microorganisms is achieved in the compost tea.
