An organic fertilizer heavy metal passivation removal equipment

Abstract

The invention relates to the field of passivation of heavy metals in organic fertilizers, in particular to the heavy metal passivation removal equipment for organic fertilizers, including a main body, a sedimentation mechanism, an adsorption mechanism, a feeding mechanism, a driving mechanism, a guiding mechanism, a wiring mechanism and a feeding mechanism. tube; put the adsorption material into the interior of the sedimentation mechanism, open the drive mechanism to make the adsorption mechanism descend to compress the adsorption material, press the adsorption material into the side wall of the adsorption mechanism, make the adsorption material distributed on the side wall of the adsorption material, and add organic Fertilizer paddle body, open the drive mechanism, so that the drive mechanism drives the adsorption mechanism to slowly move up and down and rotate inside the organic fertilizer paddle body, driving the organic fertilizer paddle body to evenly contact the adsorption material on the side wall of the adsorption mechanism, so that the adsorption material quickly absorbs organic fertilizer The heavy metal ions inside, at the same time, quickly realize the separation of organic fertilizer and adsorption material after the adsorption is completed.

Description

technical field [0001] The invention relates to the field of passivation of heavy metals in organic fertilizers, in particular to the passivation and removal equipment for heavy metals in organic fertilizers. Background technique [0002] In the process of raising pigs, feed is often added to pig food. Since the added pig feed contains a large amount of trace elements such as copper, iron, zinc, manganese, cobalt, selenium and iodine, many unabsorbed trace elements accumulate in the In livestock and poultry manure, the content of trace elements in livestock and poultry manure exceeds the standard. Pig manure is one of the important organic fertilizers. When using pig manure for fertilization for a long time, on the one hand, it is easy to cause heavy metal pollution to the soil. On the one hand, the content of heavy metals such as vegetables and fruits exceeds the standard, posing a threat to the safety of green food. [0003] The current method of processing heavy metals i...

Problems solved by technology

[0005] However, there are certain defects in the above-mentioned application. The adsorption particles made of soybean meal and bone meal as protein materials are dispersed in the inside of the organic fertilizer slurry. The internal filtration of the fertilizer increases the construction process; when the particle size of the adsorbed particles is too large, it is easy to cause the contact area between the adsorbed particles and the organic fertilizer to be small; when the particle size of the adsorbed particles is small, it is difficult to screen out the adsorbed particles from the inside of the organic fertilizer , and the adsorption particles tend to settle at the bottom of the fermenter during the fermentation process, resulting in uneven contact between the adsorption particles and the organic fertilizer, and the heavy metal ions inside the organic fertilizer cannot be quickly removed
