Abstract

The invention discloses a device for preparing organic fertilizer, which comprises a crushing unit, a fermentation tank and a biogas residue treatment tank; the biogas residue treatment tank comprisesa tank body; a treatment chamber; a collecting tank, wherein the collecting tank is used for collecting surplus biogas slurry in the treatment chamber and can move up and down relatively to the treatment chamber; a filter screen element, wherein the filter screen element capable of moving up and down is arranged in the treatment chamber; the filter screen element is provided with at least one opening, and the filter screen element is respectively provided with a platform protruding the upper surface of the opening corresponding to two sides of the opening; a driving device, wherein the driving device is used for driving the filter screen element to move downwards while driving the collecting tank to move upwards, and is used for driving the filter screen element to move upwards while driving the collecting tank to move downwards. According to the invention, the filter screen element can be driven to move downwards while the collecting tank is driven to move upwards, the working efficiency is high; the platforms are arranged on the filter screen element, so that the filter screen element is prevented from being completely immersed in the biogas slurry, therefore, the earthworms cannot be killed due to oxygen deficit, and the mortality of the earthworms is reduced.

Description

technical field [0001] The invention belongs to the technical field of rural waste utilization, and in particular relates to an organic fertilizer preparation device. Background technique [0002] For the treatment of rural solid waste, such as straw, the straw is usually crushed first, and then the crushed product is fermented to obtain biogas. After that, the biogas residue is processed through the earthworm bed, and the organic fertilizer is prepared through the earthworm. However, since earthworms will reproduce, the earthworm bed usually has too dense a density of earthworms after repeated use, and it is necessary to separate the excessive earthworms in the earthworm bed. The traditional separation methods usually use feed to lure or irradiate with strong light to make the earthworms crawl out of the biogas residue, and then collect the earthworms with tools to remove some earthworms to reduce the density of earthworms. However, this method takes a long time and has l...
