Problems solved by technology

[0002] At present, most known organic compound fertilizers are produced by adding poultry, livestock and human manure to stalks for accumulation and fermentation, and then adding various chemical fertilizers to produce powdery organic compound fertilizers. It can reach 35%, and the particle strength is small, the absorption rate is low, it cannot achieve slow release and long-term effect, and it is easy to lose when watering
In addition, urban sludge is added to livestock, human manure, straw, etc. for fermentation to produce organic compound fertilizer, and its organic matter content can only reach below 35%.
And the products made by the above-mentioned prior art are all used for field crops, and all have unpleasant peculiar smell
[0003] Some of the currently disclosed organic compound fertilizer manufacturing methods are to ferment the material and then stir it evenly into the screw extruder for granulation. Since the granulated material is not dehydrated in this method, the product is easy to ferment, so it cannot be used for long-term storage and long-distance transportation. Need; in some methods, the materials are directly dried or air-dried to make products without extrusion. The strength of the products produced by this method is very low, so the utilization rate of fertilizers after application is low, and the fertilizer effect is not long-lasting

Embodiment 1

[0017] Add 100kg of domestic sludge with 70% water content, 30kg of fermented rice husk powder, 30kg of fermented sheep dung powder, 2kg of superphosphate, and monoammonium phosphate into a two-wheel electric roller with a diameter of 1100mm and a power of 4kW. 1kg, urea 2kg, potassium sulfate 1kg, activated carbon 1kg, mixed and kneaded for 8 minutes, the material then enters a single-screw extruder (φ120mm, power 7.5kW, template hole diameter 5.0mm) and extrudes the material into smooth strips under a pressure of 8MPa Then the material is sent into the internal heat dryer (φ1200mm, length 26000m, speed 3 rpm) from the low temperature end, and the material entering the furnace is heated While rotating, the material is shaped, dehydrated, and the harmless treatment of the sludge is completed, and finally the temperature is raised to 100°C to produce granular organic compound fertilizer. Its organic matter content is 45%, and the product has no peculiar smell.

Embodiment 2

[0019] Add 100kg of domestic sludge with 80% water content, 40kg of fermented rice husk powder, 20kg of fermented straw powder, 5kg of monoammonium phosphate, 5kg of urea, and Potassium chloride 10kg, activated carbon 1.5kg, mixing and kneading for 10 minutes, the material then enters a single-screw extruder (φ120mm, power 7.5kW, template aperture 2.0mm) and extrudes the material into smooth strips under a pressure of 1MPa and immediately Cut into columnar particles, the ratio of length to diameter is 1:1, and then the material is sent from the low temperature end to the internal heating dryer (φ1200mm, length 26000m, speed 3 rpm), the material entering the furnace is heated while rotating, and the material Shaping, dehydration, and completing the harmless treatment of sludge, and finally raising the temperature to 150°C, and keeping the material in the furnace for 20 minutes to produce granular organic compound fertilizer. Its organic matter content is 50%, and the product ha...

Embodiment 3

[0021] Add 100kg of domestic sludge with 90% water content, 30kg of fermented rice husk powder, 6kg of fermented straw powder, and 4kg of fermented sheep dung powder into a two-wheel electric roller with a diameter of 1100mm and a power of 4kW. Calcium phosphate 4kg, diammonium phosphate 8kg, activated carbon 0.5kg, mixing and kneading for 10 minutes, the material then enters a single-screw extruder (φ120mm, power 7.5kW, template aperture 2.0mm) and extrudes the material into a smooth surface under a pressure of 1MPa. The strips are immediately cut into columnar particles with a length-to-diameter ratio of 1:1, and then the material is sent from the low-temperature end to the internal heat dryer (φ1200mm, length 26000m, speed 3 rpm), and the material side of the furnace Rotating while being heated, the material is shaped, dehydrated, and the harmless treatment of the sludge is completed, and finally the temperature is raised to 120°C to produce granular organic compound fertili...

Abstract

The organic composite fertilizer for flowers and plants is composed of components of A, B, C and D, in which the component A is at least one of fermented fowl and livestock manure fertilizer powder, husk powder and straw powder, B is domestic sludge, C is active carbon and D includes at least two inorganic chemical fertilizers. Its preparation method includes the steps of mixing materials, kneading, extruding, granulating and drying so as to obtain the invented fertilizer.

Description

technical field [0001] The invention relates to an organic compound fertilizer, more specifically, the invention relates to an organic compound fertilizer for flowers and a manufacturing method thereof. Background technique [0002] At present, most known organic compound fertilizers are produced by adding poultry, livestock and human manure to stalks for accumulation and fermentation, and then adding various chemical fertilizers to produce powdery organic compound fertilizers. It can reach 35%, and the particle strength is small, the absorption rate is low, the sustained release and long-term effect cannot be achieved, and it is easy to lose when watering. In addition, urban sludge is added to livestock, human manure, straw, etc. to ferment and produce organic compound fertilizer, and its organic matter content can only reach below 35%. And the products made by the above-mentioned prior art are all used for field crops, and all have unpleasant...
