Device for preparing fertilizer from wheat straws

Abstract

The invention discloses a device for preparing a fertilizer from wheat straws and aims at providing a device for preparing a fertilizer, wherein the device has the advantages that wheat straws can be effectively and centrally incinerated, the incineration process is stable and efficient, sufficient incineration can be ensured, the prepared ash fertilizer is high in purity, the generated smoke can be effectively treated, and smoke pollution can be avoided. The device comprises an incineration kiln, a feeding device and a smoke purifying device, wherein the incineration kiln is provided with an inner incineration chamber; the incineration kiln is inclined and forms a 10-60-degree angle with the horizontal plane; the inner incineration chamber is internally provided with a main transmission shaft driven by a main motor; the main transmission shaft is provided with a plurality of material dispersing bodies for stirring materials; and an air inlet, a smoke discharging part, a feeding hole and an opening / closing door for clearing materials are arranged in the incineration kiln. The device has the beneficial effects that the separation effect is good; solid particles and dust in the smoke can be removed; raw materials are dried by virtue of smoke waste heat, so that the subsequent incineration effect is improved; and the device is provided with a preheating structure, so that the subsequent incineration can be better and more sufficiently ensured.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, in particular to a device for making fertilizer from wheat straw. 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 is the most abund...

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
