Production equipment and production method of activated carbon-based soil remediation fertilizer

Abstract

The invention discloses production equipment of an activated carbon-based soil remediation fertilizer. The equipment comprises a mixing tank, wherein the outer side of the mixing tank is fixedly connected with a jacket; the bottom of the mixing tank is fixedly communicated with a discharge pipe; a refrigerating mechanism comprises a refrigerating machine, and one side of the refrigerating machinecommunicates with a first air pump and a first reversing valve through an air outlet pipe; an extrusion granulation mechanism comprises an extrusion cylinder; a heat insulation shell is further arranged on the outer side of the extrusion cylinder, an extrusion head is fixedly connected to the other end of the extrusion cylinder, an annular hollow plate is fixedly connected to the interior of the extrusion head, and one side of the annular hollow plate fixedly communicates with an air outlet needle head; one side of an air storage tank is communicated with the interior of the annular hollow plate through a pressurizing air pump and an air pipe. Through the equipment, biological activated carbon is in a relatively low-temperature state, so that the situation that the survival rate of biological activated carbon florae is reduced due to high temperature generated by mixing and extruding is avoided; an oxygen-enriched, low-oxygen or oxygen-free environment can be created in the fertilizerat will, and the flora survival number of the biological activated carbon is increased.

Description

Technical field [0001] The invention belongs to the technical field of soil remediation fertilizers, and specifically relates to a production equipment of activated carbon-based soil remediation fertilizers; in particular, it also relates to a production method of activated carbon-based soil remediation fertilizers. Background technique [0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to convert toxic and harmful pollutants into harmless substances. Fundamentally speaking, the technical principles of contaminated soil remediation can include: (1) Change the form of pollutants in the soil or the way they combine with the soil to reduce their mobility and bioavailability in the environment; 2) Reduce the concentration of harmful substances in the soil. [0003] Fixing microorganisms on activated carbon improves the adsorpt...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of production equipment and production method of activated carbon-based soil restoration fertilizer, to solve the problem of mixing and extruding fertilizers in the prior art that are collocated with biological activated carbon during granulation production in the above-mentioned background technology. Under the high temperature environment, the survival rate of the bacteria on the living activated carbon is reduced, and the shelf life of the fertilizer is relatively short, and because the nature of the bacteria is different from the living environment, when it is used with fertilizers, the effect after use cannot reach the ideal standard.
