Problems solved by technology

[0003] In the preparation of organic fertilizer, it is usually necessary to turn the organic fertilizer to provide the oxygen needed for microbial fermentation. The oxygen content in plateau areas is low, and even if the pile is turned several times, it still cannot provide sufficient oxygen for the microorganisms, which reduces the efficiency of fermentation; Repeated turning over of the compost is likely to cause the loss of heat in the compost heap, thereby causing the failure of the preparation of the organic fertilizer. Accordingly, the present invention proposes a method for preparing the organic fertilizer

preparation example Construction

[0027] Such as Figure 1 to Figure 6 Shown, the preparation method of a kind of organic fertilizer of the present invention comprises the following steps:

[0028] S1: Crushing the raw materials of organic fertilizers, adjusting the particle size of the raw materials, so that the particle size range is 12-60mm, and then mixing different raw materials to make a mixed pile. Crushing and screening can increase the surface area of ​​the raw materials, which is convenient Microbial reproduction, increase fermentation speed;

[0029] S2: Pour the stacking material mixed in S1 into the stacking device, and use the stacking device to turn the stacking material, so that the stacking material can be fermented stably; after stacking, it can be turned once every 4-7 days, After 1 month, you can stop turning the pile and let it mature naturally; blowing air into the pile increases the amount of oxygen required by the pile and improves the fermentation efficiency;

[0030]S3: After the st...

Embodiment approach

[0033] As a specific embodiment of the present invention, the air duct 19 is located on the side wall at the end of the fermentation tank 1, the angle between the air duct 19 and the bottom surface of the fermentation tank 1 is an acute angle, and the air duct 19 is located at Below the temperature-insulating cloth 13, during use, the air duct 19 is arranged at the end of the fermentation tank 1 so that the gas blown out from the air duct 19 flows from one end of the fermentation tank 1 to the other end of the fermentation tank 1, and the gas moves during the gas movement. It is gradually heated, so that the gas temperature gradually rises; the gas temperature is kept consistent with the temperature in the fermentation tank 1, so that the influence of the gas on the fermentation is reduced, and the temperature change of the microbial production environment is avoided; the gas flows from one end of the fermentation tank 1 to the fermentation tank 1 The other end overflows the fe...

Abstract

The invention belongs to the technical field of fertilizer production, and specifically relates to a preparation method of an organic fertilizer. A turning device used in the preparation method comprises a fermentation tank, two driving motors are fixed at the top end of the fermentation tank through a mounting plate; a screw rod is fixed to the output shaft end of each driving motor, sliding blocks are in threaded connection with the surface of the screw rods, a connecting rod is fixedly connected between the sliding blocks, a rotating wheel is rotatably connected to the surface of the connecting rod, two guide grooves are formed in the top end of the fermentation tank, the rotating wheel is movably installed in the guide grooves, and a rectangular plate is fixedly installed in the middleof the connecting rod. Fresh air is blown into the fermentation tank through an air duct, so that the oxygen content in the fermentation tank is kept in a reasonable range, thereby ensuring the normal fermentation; and a piled material is cut by an improved shifting block, so that the particle size of the piled material is reduced, and the oxygen-containing capacity of the piled material is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, in particular to a preparation method of organic fertilizer. Background technique [0002] Organic fertilizers are mainly derived from plants and (or) animals, and are applied to the soil to provide plant nutrition as carbon-containing materials whose main function is. It is processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances, and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. nutritional elements. It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for green food production. [0003] During the...
