A kind of inorganic potassium fertilizer manufacturing device

Abstract

The invention discloses an inorganic potash fertilizer manufacturing device assembly and is aimed at providing the device assembly which can effectively conduct a centralized burning treatment on wheat straw while achieving a stable and high efficiency burning process with guaranteed sufficient burning. Moreover, the device assembly is capable of manufacturing high purity ash fertilizer, conducting an effective treatment on flue gas generated, and avoiding flue dust pollution. The inorganic potash fertilizer manufacturing device assembly comprises a burning kiln, a feeding device and a flue gas purifying device, wherein the burning kiln is provided with a burning cavity; the burning kiln inclines and an angle of 10-60 degree is formed between the burning kiln and a horizontal plane; the inner burning cavity is internally provided with a transmission main shaft driven by a main motor; the transmission main shaft is provided with multiple material scattering objects used for stirring materials; the burning kiln is provided with an air inlet, a flue gas outlet portion, a material feeding port and an opening-closing door for scrap cleaning. The inorganic potash fertilizer manufacturing device assembly has the advantages that the separating effect is excellent; solid particles and dust in the flue gas can be eliminated; raw materials are subjected to drying by the adoption of residual heat of the flue gas so that a subsequent burning effect can be improved; a preheating structure is arranged so that subsequent burning can be guaranteed better and more sufficiently.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to an inorganic potash fertilizer manufacturing device. Background technique [0002] At present, there are often many plants that are difficult to handle and have little use value, such as weeds in the garden, dead wood, broken branches of plants, crop straw, etc. Among them, the generation of wheat straw in our country every year The amount is quite large. If wheat straw or other plants are directly used as fertilizers for landfill, due to their relatively large size, slow decomposition, and poor actual fertilizer supply capacity, it is easy to cause many negative effects. Therefore, it can be selected to be incinerated centrally, so as to be burned into plant ash fertilizer for rational use. Plant ash is the ashes of various plants after burning, so almost all the mineral elements contained in plants are contained in plant ash. Among them, potassium i...

Problems solved by technology

However, at present, in the process of burning fertilizer, there are several main shortcomings: it is easy to produce a large amount of solid particles, thereby forming smoke and dust, which has adverse effects on the surrounding environment; because of centralized burning, it is easy to appear insufficient burning process , the utilization rate of raw materials is limited and the content of impurities will be too high; and because there are many impurities and residual materials in the plant ash fertilizer made, follow-up treatment is required, which increases the process and has a negative impact on production efficiency and cost
