Embodiment 1

[0038] The present invention provides Figure 1-6 The shown production equipment of activated carbon-based soil remediation fertilizer includes: a mixing tank 1, the outer side of the mixing tank 1 is fixedly connected with a jacket 2, and the bottom of the mixing tank 1 is fixedly connected with a discharge pipe 6, and The discharge pipe 6 is equipped with a discharge valve 7; a refrigeration mechanism, the refrigeration mechanism includes a refrigerator 10, one side of the refrigerator 10 is connected with a first air pump 12 and a first reversing valve through an air outlet pipe 11 13, and one side of the refrigerator 10 is connected with the second reversing valve 15 through the air inlet pipe 14; an extrusion granulation mechanism, the extrusion granulation mechanism includes an extrusion cylinder 21, the outside of the extrusion cylinder 21 A heat-insulating housing 17 is also provided. One end of the extrusion cylinder 21 is fixedly installed with an extrusion motor 16 f...

Embodiment 2

[0047] Different from the attachment of anaerobic flora on biological activated carbon in Example 1, this example attaches aerobic microbial flora on biological activated carbon; therefore, the carbon dioxide gas storage tank is replaced with an oxygen gas storage tank, and the oxygen gas storage tank It contains a mixed gas of oxygen and nitrogen. The oxygen content is 30-45%, and the oxygen content is higher than that of the air, but it should not be too high. Too high can easily lead to accelerated aging of microorganisms, thereby reducing the survival rate of microorganisms , Resulting in a reduction in the shelf life of fertilizers.

Embodiment 3

[0049] Different from the attachment of anaerobic flora on biological activated carbon in Example 1, this example attaches anaerobic microbial flora on biological activated carbon; therefore, the carbon dioxide gas storage tank is replaced with a nitrogen gas storage tank, and the nitrogen gas storage tank It contains a mixed gas of oxygen, nitrogen and carbon dioxide, wherein the oxygen content is 5-10%, the nitrogen content is 90-95%, and the carbon dioxide content is less than 1%.

[0050] In summary: the above three groups of embodiments can reasonably adjust the gas composition according to the type of bacteria, so as to create a suitable environment during granulation. The present invention realizes the jacketing of the mixing tank and the extrusion cylinder through a set of refrigerators. Switching refrigeration during use makes the biological activated carbon at a relatively low temperature during the mixing and extrusion granulation process, avoiding the high temperature ...

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...
