Embodiment Construction

[0029] The method for distributing material on the roof of a nitriding furnace for the production of lime nitrogen multifunctional fertilizer comprises the following steps:

[0030] Step 1: Grind calcium carbide and other additives to below 60 mesh, said other additives include returned lime, nitrogen, etc., and mix them evenly;

[0031] Step 2: Stack the mixed material in the silo, push the material through the rake plate, so that the material is evenly dispersed in the silo;

[0032] The above-mentioned silo is a circular silo, and the center of the bottom surface of the silo is provided with a drop hole, and the rake plate is a square plate, one side of which is close to the bottom surface of the silo, and the rake plate rotates around the drop hole to push the material;

[0033] Step 3: After the material rotates and disperses with the rake plate, it continues to be agitated by the rake plate, and falls from the drop hole when it moves to the center of the silo;

Abstract

A method for distributing material on the top of a nitriding furnace for the production of lime nitrogen multifunctional fertilizer, which relates to the technical field of lime nitrogen multifunctional fertilizer production, including crushing and mixing, pre-distributing, rake plate pushing and dropping material at a uniform speed, material falling to a spreading table, blowing pipe Blowing reactive nitrogen gas to the spreading table, so that the materials falling to the spreading table are impacted and dispersed by the reactive nitrogen gas, and evenly settled in the nitriding furnace and other process steps; Gas chamber, blowpipe, rake plate, blowpipe shaft and spreading platform; the present invention uses reactive nitrogen gas as the medium gas to realize uniform distribution of materials with reactive nitrogen gas flow, and at the same time realizes heat exchange and cooling of the distributor, reducing the corresponding equipment maintenance and use costs.

Description

Technical field: [0001] The invention relates to the technical field of lime nitrogen multifunctional fertilizer production, in particular to a method for distributing material on the top of a nitriding furnace and equipment thereof for the production of lime nitrogen multifunctional fertilizer. Background technique: [0002] Lime nitrogen is a mixture composed of calcium cyanamide, calcium oxide, etc. It is an alkaline fertilizer and can also be used as a herbicide, fungicide, insecticide, etc. Currently, crushed calcium carbide is used to heat it to 1100 degrees Celsius and pass it into the Produced by way of nitrogen reaction. [0003] In the process of using calcium carbide to produce lime nitrogen through nitriding furnace reaction, the calcium carbide material needs to be evenly spread in the nitriding furnace, so it is necessary to install a distributor on the top of the nitriding furnace. [0004] In the existing technology, the distributor adopts a sliding distribu...
