DESCRIPTION

Technical field of invention:

[001] Present invention in general relates to the field of agriculture and more particularly to a cow dung slurry filtration apparatus used in the preparation of organic liquid manures.

Background of the invention:

[002] Cow dung slurry or jeevamrut/ amrutjal are important liquid manures applied in farming especially in organic farming and natural farming. It requires preparation of these mixtures by putting ingredients such as cow dung, cow urine, soil, cereal floor, jaggery, etc. in different combination in water as per the need. The prepared slurry is required to be filtered so that it can be sprayed on the crops and can also be supplied to the soil through drip irrigation. The slurry usually has floating particles of cow dung, soil etc. Fine filtered slurry is required so as to prevent the clogging of holes of the spray pump and the drip lines. The contents of the ingredients are required to be mixed twice a day with bamboo stick. Also it is required that no movement of the solution should happen at least for eight hours before the usage so that the floating particles settle down at the bottom of the tank. Although various attempts are made before, for providing various means for the filtration of slurry and few of them are discussed below.

[005] US7975850B2 discloses apparatus and method for separating sand from manure slurry. A separation apparatus (A) separates particulates such as sand from slurry of water/sand/manure. Particularly, passage receives the slurry and injectors assist the slurry over ramp and aid in separating the sand and organic material from the slurry. The sand proceeds through a discharge and preferably a counter flow of sanitizer from sterilizing passage proceeds through the sand. Cleaned and sanitized sand is temporarily stored in a collector.

[006] CA2877582A1 discloses high-efficiency dynamic slurry-liquid-separating filtration apparatus and filtration method there for. The filtration apparatus comprises a filter cylinder body, a filter pipe and a filter core on the filter pipe arranged within the filter cylinder body, a material inlet on the filter cylinder body, a solid residue outlet provided at the bottom part of the filter cylinder body, and a filtrate outlet provided at the mid-bottom part of the filter cylinder body, where the filter core is multiple filter plates connected with the filter pipe, where the filter plates are perpendicular to the longitudinal axis of the filter cylinder body, and where the upper end of the filter pipe is connected to a rotary shaft of an inverter motor. The filtration method comprises: preheating the filtration apparatus; after filtering for a period of time, adjusting the rotational speed of the inverter motor, thus removing a thin layer of filter residue cake on the filter plates.

[007] US5741419A discloses filter press for filtering liquid slurries. An apparatus for filtering liquid slurry is described. The apparatus uses a pair of filter chambers formed by a pair of fixed plates, and a pair of opposed moveable plates. The moveable plates are moved into engagement with the fixed plates by the downward movement of a wedge member disposed between the plates and, the plates are bias so that when the wedge member is withdrawn, the plates will be drawn together opening the filter chambers. The chambers are sealed by opposed actuate gaskets so that the sealing action is achieved by internal pressure rather than the pressure driving the plates together. A filter media is provided on a continuous roll which extends between the gaskets and is intended to carry the filter cake out of the chamber when the plates are separated whereupon the cake will be dropped from the filter media into a collection area so that the filter media can be reused.
