Device for converting sludge into fertilizer

Abstract

A device for converting sludge into a fertilizer comprises a main shell; a drying and dewatering chamber is formed in the main shell, and a rotary drying device is arranged in the drying and dewatering chamber, so that the sludge can be further dewatered and dried to be converted into granules from a fluid state; and a rotary feeding device is arranged on the upper side of the drying and dewatering chamber in a communicating manner, so that the rotary drying device is correspondingly filled with sludge. Through a primary filtering device in the sludge treatment device, the quality of sludge can be effectively and preliminarily improved, the water content can be effectively and preliminarily reduced, and the effect of fertilizer for subsequent processing treatment is improved. The rotary feeding device can effectively and reasonably transport the sludge, so that the processing automation performance is guaranteed. The rotary drying device can prevent dehydrated sludge from caking and shape the dehydrated sludge into granules, so that subsequent fertilizer production is facilitated; in addition, the switching device can perform function switching selection through different states, so that the intelligent automation performance of the whole device is improved.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a device for converting sludge into fertilizer. Background technique [0002] Sludge treatment is the process of treating, solidifying, dehydrating, stabilizing, drying or incinerating sludge, and sludge fertilizer is a kind of fertilizer made from untreated primary sedimentation sludge, which is dehydrated, dried and mixed with chemical fertilizers. , it is necessary to remove most of the water content from the sludge through infiltration or evaporation, and then add chemical fertilizers. However, the structure of the traditional sludge-to-fertilizer device is too simple and requires a lot of manpower to operate, and the automation performance needs to be improved. To meet the comfort of personnel, there is the problem of low efficiency and effect of sludge treatment. Reasonable cost control and no recovery function will cause a certain waste. It cannot be equipped with...

[0002] Sludge treatment is the process of treating, solidifying, dehydrating, stabilizing, drying or incinerating sludge, and sludge fertilizer is a kind of fertilizer made from untreated primary sedimentation sludge, which is dehydrated, dried and mixed with chemical fertilizers. , it is necessary to remove most of the water content from the sludge through infiltration or evaporation, and then add chemical fertilizers. However, the structure of the traditional sludge-to-fertilizer device is too simple and requires a lot of manpower to operate, and the automation performance needs to be improved. To meet the comfort of personnel, there is the problem of low efficiency and effect of sludge treatment. Reasonable cost control and no recovery function will cause a certain waste. It cannot be equipped with a cleaning function to facilitate the next use without the previous device. Therefore, it is necessary to design a safe and efficient device for using sludge to fertilize
