Equipment for preparation of organic fertilizers from solid waste

Abstract

The invention discloses equipment for preparation of organic fertilizers from solid waste. The equipment includes: a pool body; a treatment chamber; a liquid collection chamber, which is used for collecting redundant biogas liquid in the treatment chamber, is disposed below the treatment chamber, and can move up and down relative to the treatment chamber; a transfusion component, which is used forcommunicating the treatment chamber and the liquid collection chamber, and includes first liquid channels and a plurality of second liquid channels disposed under the first liquid channels; and a filter device, which includes first filter pieces matching the first liquid channels and second filter parts and flexible liquid flow parts that match the second liquid channels. According to the invention, biogas residue is filtered by the filter pieces and filter parts, outflow of biogas residue from the treatment chamber along with the biogas residue can be avoided, and the circumstance of material loss can be avoided; secondly, the equipment is also equipped with the flexible liquid flow parts, the flexible liquid flow parts can be opened only under the action of an external force, and then can cooperate with an opening-closing device to realize better cut-off of the second liquid channels, thus avoiding leakage.

Description

technical field [0001] The invention belongs to the technical field of solid waste reuse, in particular to a device for preparing organic fertilizer from solid waste. Background technique [0002] In rural areas, a large amount of solid waste is often produced, such as agricultural straw; the traditional treatment method is usually to produce biogas by crushing and fermenting, and then use earthworms to process the biogas residue to prepare organic fertilizer. Due to the extremely fast reproduction speed of earthworms, it is easy to have an excessively high density of earthworms in this way, so the earthworms need to be separated regularly. [0003] The traditional separation methods are feed induction or strong light irradiation, which consume a lot of resources and take a long time. In order to solve the above problems, it appears that the biogas slurry collected during the treatment process is returned to the treatment chamber, so that the earthworms drill out to the wat...

Problems solved by technology

[0004] However, in this method, the waste liquid is usually pumped into the treatment chamber through pipelines and power pumps, and after the earthworms are separated, the waste liquid is pumped out of the treatment chamber, which consumes a lot of energy, takes a long time, and is inefficient.
