Cooling device for fertilizer production

Abstract

The invention discloses a cooling device for fertilizer production. The cooling device for fertilizer production comprises a shell, wherein a cooling groove and a zigzag pipe groove are formed in theshell; a cooling pipe is fixedly arranged in the middle of the groove bottom of the cooling groove; multiple airflow through grooves distributed in an annular array mode are formed in the outer side of the cooling pipe; multiple airflow through holes distributed in an annular array mode with the cooling pipe as the circle center are further formed in the groove bottom of the cooling groove; a zigzag pipe is fixedly arranged in the middle of the groove bottom of the zigzag pipe groove; and branch air pipes matched with the airflow through holes are fixedly connected to the top face of the zigzag pipe. According to the cooling device for fertilizer production provided by the invention, the cooling pipe is fixedly arranged in the middle of the groove bottom of the cooling groove, the multipleairflow through grooves distributed in the annular array mode are formed in the outer side of the cooling pipe, the multiple airflow through holes distributed in the annular array mode with the cooling pipe as the circle center are further formed in the groove bottom of the cooling groove, the airflow through holes are distributed in different positions of the groove bottom, and the airflow through grooves are matched with the airflow through holes, so that the cooling efficiency of the device on a fertilizer pile can be improved, and the device can accelerate the cooling of the fertilizer pile.

Description

technical field [0001] The invention relates to the technical field of waste production cooling, in particular to a cooling device for fertilizer production. Background technique [0002] The budding period of the fertilizer and fertilizer industry From the 1840s to the First World War was the budding period of the fertilizer and fertilizer industry. At that time, humans attempted to use artificial methods to produce fertilizers to supplement or replace natural fertilizers, and the production of phosphate and potash fertilizers began. It is earlier than nitrogen fertilizer because of the long-term implementation of green manure crops and food crop rotation system and the extensive use of organic fertilizers in agricultural farming; [0003] In the fertilizer production process, in order to improve the packaging efficiency of fertilizers, fertilizers are often cooled. At present, when cooling chemical fertilizers in the prior art, they are generally piled up for cooling, and ...

AI Technical Summary

Problems solved by technology

[0003] In the fertilizer production process, in order to improve the packaging efficiency of fertilizers, fertilizers are often cooled. At present, when cooling chemical fertilizers in the prior art, they are generally piled up for cooling, the cooling efficiency is relatively low, and the internal heat of the accumulated fertilizers is difficult There are problems of poor cooling quality, low work efficiency, high labor intensity of operators, and inconvenient bagging operation. Therefore, it is necessary to invent a cooling device for fertilizer production to solve the above problems
