Description

Technical Field

[0001] The utility model relates to the field of planting soil production and processing, in particular to a production device for planting soil using silt as a base material. Background Art

[0002] A large amount of river silt is often generated during river channel construction or reservoir regulation. Faced with such a large amount of silt, traditional treatment methods often use simple stacking and natural drying. On the one hand, it requires a large amount of space for silt stacking, and natural drying usually takes a long time. In the case of limited urban land area, it often causes a large amount of waste of resources. On the other hand, the stacking process may also cause secondary pollution to the stacking area. Therefore, finding a reasonable silt treatment method has always been a difficult problem faced in dredging projects. There are many methods for silt treatment, such as using silt for composting and fermentation to make organic fertilizer, but due to the relatively high production cost, this off-site treatment method is not the first choice for engineering projects. On-site solidification treatment is a widely used method in production. In fact, after years of sedimentation, the organic matter and nutrient content of lake bottom silt is often high. Converting silt into garden planting soil solves the silt treatment problem and achieves the safe disposal and sustainable resource utilization of silt. Utility Model Content

[0005] By adopting the above technical solution, the sludge after preliminary dehydration is injected into the feeding chamber through the feeding port, and at the same time, the crushed agricultural waste (preferably peanut shells, but also fallen leaves or straw, etc.) is injected into the feeding chamber through the feeding port at the other end. The mixing mechanism mixes the sludge with the crushed agricultural waste. The addition of enzymes during mixing helps to reduce the fixed precipitation of soil nutrients, so that the nutrients can be fully absorbed by plants. At the same time, the silver ion solution is one of the types with the lowest minimum inhibitory concentration among all metal ions, and it is non-toxic and colorless. When added to the sludge, it can kill most of the bacteria in the sludge, and the silver ions are almost not consumed or lost during use. , long service life, saving use cost, and before the input pipe enters the feed chamber, adding nano silicon dioxide powder can improve the strength and hardness of the soil, and utilizing the large specific surface area, surface multi-mesoporous structure and super adsorption capacity and unique physical and chemical properties of nano SiO2, functional ions such as silver ions are evenly designed into the mesopores on the surface of nano SiO2, thereby enhancing the antibacterial performance, performing bactericidal effects and removing toxic heavy metals.

[0015] By adopting the above technical solution, the preheating mechanism can adopt common heating methods such as wind heating or electric heating to maintain a certain temperature in the conveying pipe, preheating for the next step of drying, improving the drying efficiency, and at the same time increasing the temperature in steps to improve the quality of the finished soil product.
