Products FAQ

Nowadays, the social pollution is becoming more and more serious, and there are more and more kinds of pollutants, such as agricultural waste, livestock manure, industrial waste, domestic garbage, and urban sludge. How to make rational use of organic fertilizer aerobic fermentation tank to innocuously treat these pollutants into organic fertilizer and return them to the soil, improve the land fertility, and ensure the quality of life and ecological breeding is a huge problem currently facing. However, long-term unreasonable use of chemical fertilizer in farmland is likely to cause imbalance in the proportion of nutrients in land and farmland, damage the farmland ecology, and affect the quality and safety of agricultural products.Livestock and poultry dung: such as chicken dung, cattle, sheep, horse dung, rabbit dung;Industrial wastes: such as distiller's grains, vinegar grains, cassava residues, sugar residues, furfural residues, etc;Domestic waste: such as kitchen waste;Urban sludge: such as river sludge, sewage sludge, etc. Classification of organic fertilizer raw material production and supply bases: silkworm excrement, mushroom residue, kelp residue, phosphocitric acid residue, cassava residue, protein mud, sugar formaldehyde residue, amino acid humic acid, oil residue, plant ash, shell powder, etc., and peanut shell powder.Agricultural wastes: such as straw, soybean meal, cotton meal, etc.Organic fertilizer, commonly known as farmyard manure, refers to slow acting fertilizer containing a lot of biological substances, animal and plant residues, excreta, biological waste and other substances. The organic fertilizer not only contains the necessary macroelements and microelements for plants, but also contains rich organic nutrients. The organic fertilizer is the most comprehensive fertilizer.Organic fertilizer is organic solid waste decomposed by aerobic microorganisms in the organic fertilizer aerobic fermentation tank, which generates a large amount of heat with a temperature of more than 70 degrees, effectively killing bacteria and grass seeds in the waste, and produces organic fertilizer after complete decomposition. The organic fertilizer can be directly used for economic crops such as orchard, agricultural and vegetable bases, and can also be added with a certain proportion of chemical fertilizer, A compound fertilizer containing a certain proportion of organic matter that is fully mixed and granulated by technology.

In order to promote aerobic fermentation, the following conditions shall be met:Moisture content; air Temperature; PH value; Carbon nitrogen ratio; It shall not contain chemicals that hinder the colonization of high-temperature bacteria; In order to speed up the drying process of products and enhance the uniformity of products, the air supply system needs to continuously supply appropriate air volume. The above items are necessary conditions.This type of fermenter is a system for feeding organic fertilizer from the top and unloading organic fertilizer from the bottom of the equipment. The fermentation composting cycle is generally 6-10 days (depending on the composition, water content and treatment cycle of raw materials).moisture contentIn order to effectively ferment, the fermenting layer in the tank must maintain a moisture content of 50% - 60%.This equipment is a device with a deep fermentation tank. Due to the residual fermentation substance (bacterial bed) in the tank at ordinary times, it is necessary to input high moisture raw materials with appropriate water and mixed by stirring.airThe reproduction degree of aerobic microorganisms in the fermentation process will change slightly under the influence of the surrounding environment. The principle of this equipment is aerobic biological fermentation. The high-pressure air supply system of the equipment supplies air continuously through the mixing shaft at the bottom of the equipment and the vent of the mixing blade. The air supply volume is adjusted according to the fermentation state to create a suitable purple environment for aerobic microorganisms to reproduce vigorously, so that the decomposed materials can be decomposed completely and quickly, and the eggs and grass seeds can be killed.temperatureThe temperature between 50 ℃ and 70 ℃ is the ideal temperature for aerobic microorganism propagation. The operating temperature of this equipment will vary according to the content of organic matter in the material. The operating temperature is usually about 60 ℃.PH value, carbon nitrogen ratioIn order to effectively ferment, the fermenting layer in the tank must maintain a moisture content of 50% - 60%. This equipment is a device with a deep fermentation tank. Since there are usually fermented substances (bacterial beds) left in the tank, it is necessary to input water free raw materials with appropriate water and mixed by stirring.

Type of screw conveyorThere are many kinds of screw conveyors, including U-shaped screw conveyor, pipe screw conveyor, auger conveyor, cement conveyor, pipe fly ash feeder, shaft screw conveyor and double shaft screw conveyor.Advantages of screw conveyorScrew conveyor is a kind of machinery that uses the motor to drive the screw to rotate and move materials to achieve the purpose of conveying. Compared with other auger conveyors, it can be transported horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, convenient closed transportation, etc. Screw conveyor can be divided into axial screw conveyor and shaftless screw conveyor in terms of conveying form, and can be divided into U-shaped screw conveyor and tubular screw conveyor in terms of appearance. The shaftless screw conveyor is suitable for non viscous dry powder materials and small particle materials (such as cement, fly ash, lime, grain, etc.), while the shaftless screw conveyor is suitable for the conveyor to be made of viscous and easily entangled materials. (For example: sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the rotating screw blades move the materials and carry out the screw conveyor conveying. The force that makes the materials not rotate with the screw conveyor blades is the weight of the materials themselves and the friction resistance of the screw conveyor housing to the materials. The spiral blades welded on the rotating shaft of the screw conveyor have solid surface, belt surface, blade surface, etc. according to the different materials conveyed.
