[0013] Preferably, there are 36 to 48 tank-type wet fermentation devices for animal protein organic fertilizer working in parallel.

[0014] Preferably, there are 8 to 10 dry-wet separators working in parallel.

[0015] The processing flow of the animal protein organic fertilizer supporting system is as follows:

[0016] First high-temperature drying: animal slaughter residues, feces from animal farms, fish, shrimp, crabs, eggshells and other processing residues collected from slaughterhouses or other places are first classified, and high-purity animal protein is extracted after pre-classification. The remaining residues are then transported to the first set of high-temperature drying furnaces (31) through a fully enclosed conveyor belt, and the organic fertilizers are sterilized and disinfected at high temperature in the equipment in a short time to prevent plague, bacterial diseases, odor, exhaust gas, etc.;

[0017] First removal of flue gas and nitrogen, phosphorus and potassium separation: Since flue gas is generated by high-temperature treatment in the first set of high-temperature drying furnaces 31, the present invention equips the first set of high-temperature drying furnaces 31 with a first set of flue gas adsorption and odor separation nitrogen, phosphorus and potassium purification devices 39 to purify the flue gas discharged by the high-temperature dryer and capture the flue gas odor, nitrogen, phosphorus and potassium in the flue gas;

[0018] Crushing: The organic fertilizer discharged after drying is then transported to the crusher 32 for crushing to facilitate subsequent uniform fermentation;

[0019] Dry powder mixing: The semi-finished fertilizer discharged after crushing is transported to the dry powder mixing device 33. According to the needs of organic fertilizer, nitrogen, phosphorus, potassium, organic matter, organic acid, calcium, calcium sulfate, fat, polysaccharide, vitamin B, fiber, potassium chloride and other elements are added and mixed; the animal protein organic fertilizer can be released in batches for 6 times and slowly absorbed by crops and soil.

[0020] Wet mixing: The mixed organic fertilizer from the previous mixing device enters the wet fermentation organic fertilizer mixing device 11, and is diluted and mixed evenly with appropriate amount of water;

[0021] Tank animal protein organic fertilizer wet fermentation: wet fermentation is carried out in 36 to 48 groups of vertical wet fermentation tanks 1;

[0022] Dry-wet separation: After wet fermentation, the organic fertilizer enters the dry-wet separator 34 for dehydration;

[0023] Second high-temperature drying: The dehydrated fertilizer enters the second set of high-temperature drying furnaces 35 for further drying;

[0024] Secondary removal of dust and waste gas, nitrogen, phosphorus and potassium separation: Since the fertilizer after wet fermentation will produce methane, odor, waste gas and other odors, it is purified and separated and recovered by the second set of high-temperature drying furnace 35 high temperature treatment, and is also one of the materials used to repair the decomposition of pesticide residues in the soil;

[0025] Cooling and thawing: The high-temperature fertilizer enters the cooling and thawing device 36 to cool down in order to facilitate subsequent continuous production operations.

[0026] Quantitative preparation of multiple raw materials: The thawed fertilizer from the previous station is connected to the quantitative preparation of multiple raw materials mixing device, and then animal protein and 20 to 48 elements are added according to the purpose and needs of the fertilizer for mixing;

[0027] Granulation: The fertilizer enters the granulator for granulation and shaping. After the granules are shaped, they are transported to the packaging workshop for packaging.

[0028] The present invention has at least the following beneficial effects:

[0029] This program uses tank-type animal protein organic fertilizer with wet fermentation. Through 36 to 48 groups of independent vertical wet fermentation tanks, filling one tank every day is conducive to uniform mixing and ensuring fermentation penetration, etc. The number of tanks will be determined according to the needs. According to the needs of fertilizers, more than a dozen animal raw materials mixed in the previous station and more than a dozen elements are added, mixed evenly into one, and evenly penetrated by wet fermentation, which is conducive to repairing the thinness and compaction of the soil, and the decomposition and repair of pesticide residue pollution in the soil for decades, changing the structure of the soil into fertile as follows: it will loosen, absorb, decompose, transform, change color, exhaust, cultivate beneficial microorganisms, cultivate a variety of trace elements for crops and soil absorption, and cultivate a variety of nutrients that are released in multiple times to be slowly absorbed by crops and soil.

[0030] By pre-extracting useful protein at room temperature, first extract high-purity animal protein from the collected raw materials, and then treat the remaining raw materials at high temperature, avoiding the high-temperature furnace. Once entering the high-temperature furnace, all animal proteins will naturally turn into mature materials, and all the animal protein effects will be lost, becoming a single-element organic fertilizer. There is no way to cultivate microorganisms and beneficial bacteria in the soil. Therefore, after the animal protein is extracted at the first stop, the remaining residue is sterilized at high temperature to prevent plague, fungal diseases, odor, exhaust gas, etc., and then undergo high-temperature incineration and drying of organic fertilizer. The quality of the fertilizer is not greatly affected; then wet fermentation is carried out; high temperature is used again to remove odors and separate useful substances; nitrogen, phosphorus, potassium and other elements in the smoke and exhaust odor are captured in the flue gas, and then added in appropriate procedures, which greatly improves the effect of organic fertilizer. In this device, dozens of elements are adsorbed, condensed, captured and separated. It is mainly used to solve the problem of 50-60% of pesticide residues that have fallen into the soil when pesticide sprays have been used for decades. The dust-free, odorless, colorless and harmless airflow discharged after purification by this device meets international, EU and Chinese environmental emission standards.

[0031] The entire system adopts fully enclosed collection of dust, smoke and odor for centralized treatment, which completely solves the problem of odor emission to the outside world in the current fertilizer production line, which is not environmentally friendly. The fermentation supporting system of the present invention complies with international, EU, Chinese and other environmental protection emission standards, thereby ensuring that the entire system can achieve dust-free, smoke-free, odorless and harmless emission standards for the entire production line.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Please refer to Figures 1 to 5. The tank-type wet fermentation device for animal protein organic fertilizer includes a vertical wet fermentation tank 1. The upper portion of the wet fermentation tank 1 is provided with a plurality of clean water outlets 13. The top two sides of the wet fermentation tank 1 are provided with air inlet 19 and mixed gas outlets 20 for biogas, waste gas, odor, and other peculiar smells. The biogas, odor, waste gas, and other peculiar smells are discharged through pipes connected to the exhaust pipes and pumped to the combustion chamber of a high-temperature drying furnace for high-temperature incineration and treatment, while reducing energy consumption and lowering operating costs. The left side of the top cover of the wet fermentation tank is provided with a pipe for an air compressor to input compressed air to keep biogas, odor, and waste gas in and out. Intake balance; the inner wall of the wet fermentation tank 1 is installed with a timing and quantitative switch valve 17 for controlling the liquid level in the fermentation tank. Two groups of high-pressure pumping pumps 12 and two groups of high-pressure circulating pumping pumps 14 are provided at the bottom of the wet fermentation tank 1. The output ends of the two groups of high-pressure pumping pumps 12 are fixedly installed on the top of the wet fermentation tank 1 through pipes. The output ends of the two high-pressure circulating pumping pumps 14 extend into the lower part of the wet fermentation tank 1 through pipes, and are provided with multiple groups of water nozzles 16 at the end. The input ends of the two high-pressure circulating pumping pumps 14 are connected to the clean water outlet 13, and the two outer side walls of the bottom of the wet fermentation tank 1 are each provided with an arched inlet and outlet 23.

[0041] When the tank-type animal protein organic fertilizer wet fermentation device is working, the slurry raw materials from the wet fermentation organic fertilizer mixing device 11 are pumped into the tank body of the wet fermentation tank 1 through two groups of high-pressure pumps 12.

[0042] Each set of wet fermentation tanks is provided with two clear water outlets 13 near the top. Since the residue will naturally settle downward approximately 12 hours after the fermentation tank is filled, the solution at the top of the fermentation tank is relatively dilute, clear water. Two sets of high-pressure circulating pumps 14 pump the relatively dilute solution at the upper clear water outlet 13 to the lower part of the tank body. Multiple sets of water nozzles 16 are provided at the end to form a high-pressure conveying system. Under the action of pressure spraying, the slurry fertilizer at the bottom is sprayed from top to bottom for uniform mixing, which is equivalent to stirring and is conducive to fertilizer fermentation. The arrangement of the water nozzles is shown in FIG3 . Preferably, there are 12 to 30 water nozzles 16, which are arranged in a planar manner. Each water nozzle 16 sprays water in a clockwise or counterclockwise tangential direction, advancing forward to form a rotating shape to mix uniformly and prevent the fertilizer from condensing and settling at the bottom. The high-pressure pump is started regularly every day to connect to the clear water discharged from the top. The high-pressure pump is connected and pumped for 10 to 20 minutes to spray uniformly and loosen the fertilizer.

[0043] A fully automatic timed and quantitative electric switching valve is installed near the top of the tank body to control the height of the tank content.

[0044] In an optional embodiment, the inner bottom of the wet fermentation tank 1 is a funnel-shaped concave slanted bottom 22, which facilitates the discharge of fertilizer in the middle; two sets of discharge pumps 25 are provided at the bottom of the wet fermentation tank 1, and the input end of the discharge pump 25 is connected to the bottom of the funnel-shaped concave slanted bottom 22 in the wet fermentation tank 1 through a pipeline; an enlarged tee is provided on the outside in the middle of the concave slanted bottom of the bottom cover of the wet fermentation tank, which is connected to discharge the fertilizer after the wet fermentation is completed, and all of it is pumped to the next station wet-dry separator through a closed pipeline.

[0045] In an optional embodiment, the side wall of the wet fermentation tank 1 is provided with an enlarged oblong flange opening 18 to facilitate maintenance, installation and cleaning; an enlarged flange opening 21 is provided in the middle of the top of the wet fermentation tank 1 to facilitate maintenance, installation and cleaning; valves are installed on the pipes where the air inlet 19 and the mixed gas outlet 20 are located.

[0046] A supporting system for animal protein organic fertilizer includes a first set of high-temperature drying furnaces 31 → a crusher 32 → a dry powder mixing device 33 → a wet fermentation organic fertilizer mixing device 11 → a vertical wet fermentation tank 1 → a dry-wet separator 34 → a second set of high-temperature drying furnaces 35 → a cooling and thawing device 36 → a device for quantitatively mixing multiple raw materials 37 → a granular forming machine 38, which are connected in sequence; the above-mentioned process equipment is connected in sequence by a fully enclosed conveyor belt or enclosed pumping to transport the processed animal protein organic fertilizer.

[0047] Furthermore, the first set of high-temperature drying furnaces 31 is connected to a first set of smoke removal, waste gas adsorption, odor separation, nitrogen, phosphorus and potassium purification devices 39; the second set of high-temperature drying furnaces 35 is connected to a second set of smoke removal, waste gas adsorption, odor separation, nitrogen, phosphorus and potassium purification devices 40.

[0048] In an optional embodiment, there are 36 to 48 tank-type wet fermentation devices for animal protein organic fertilizer working in parallel.

[0049] In an optional embodiment, there are 8 to 10 dry-wet separators 34 working in parallel.

[0050] The processing flow of the animal protein organic fertilizer supporting system is as follows.

[0051] 1) First high-temperature drying: Animal slaughter residues, feces from animal farms, fish, shrimp, crabs, eggshells and other processing residues collected from slaughterhouses or other places are first classified, and high-purity animal protein is extracted after pre-classification. The remaining residues are then transported to the first set of high-temperature drying furnaces (31) through a fully enclosed conveyor belt, and the organic fertilizers are sterilized and disinfected at high temperature in the equipment for a short time to prevent plague, bacterial diseases, odor, exhaust gas, etc. The purpose of pre-classifying and refining the high-purity animal protein is to avoid high-temperature furnaces. Once entering the high-temperature furnaces, all the animal protein will naturally turn into clinker, and the animal protein effect will be completely lost, becoming a single-element organic fertilizer. There is no way to cultivate microorganisms and beneficial bacteria in the soil. Therefore, after the animal protein is refined at the first station, the remaining residue is transported to the first set of high-temperature drying furnaces 31. The first time it enters the high-temperature furnace, it is connected to the drum for rotary flow dispersion, and the organic fertilizer is sterilized and disinfected at high temperature in the equipment for a short time to prevent plague, fungal diseases, and odor, waste gas, etc. The high-temperature incineration and drying of the organic fertilizer has little effect on the quality of the fertilizer.

[0052] The first removal of flue gas and nitrogen, phosphorus and potassium separation: Since flue gas will be generated by high-temperature treatment in the first set of high-temperature drying furnaces 31, the present invention equips the first set of high-temperature drying furnaces 31 with a first set of flue gas adsorption and odor separation nitrogen, phosphorus and potassium purification devices 39 to purify the flue gas discharged by the high-temperature dryer and capture the flue gas odor, odor, nitrogen, phosphorus and potassium in the flue gas. After the various elements are converted by incineration in the previous station in the high-temperature furnace, dozens of elements are adsorbed, condensed and separated in this device, which is mainly used to solve the problem of decomposing pesticide residues in the soil geology for decades. Among them, the separated useful substances are added and mixed in the quantitative preparation of multiple raw materials. The dust-free, odorless, colorless and harmless airflow discharged after purification by this device meets the international and EU environmental emission standards and China's environmental emission standards.

[0053] 2) Crushing: The organic fertilizer discharged after drying is then transported to the crusher 32 for crushing to facilitate subsequent uniform fermentation. The semi-finished fertilizer discharged from the high-temperature dryer is transported to the crushing room in a fully enclosed manner for crushing to prevent dust and odor from leaking out. All of it is collected and purified.

[0054] 3) Dry powder mixing: The semi-finished fertilizer discharged after crushing is transported to the dry powder mixing device 33, and various elements such as nitrogen, phosphorus, potassium, organic matter, organic acid, calcium, calcium sulfate, fat, polysaccharide, vitamin B, fiber, potassium chloride, etc. are added according to the needs of organic fertilizer and mixed;

[0055] 4) Wet mixing device: The mixed organic fertilizer from the mixing device of the previous station enters the wet fermentation organic fertilizer mixing device 11, is diluted and mixed evenly with an appropriate amount of water, and then transported to the next station for wet fermentation supporting system to prevent the high temperature generated during dry fermentation from burning the nutritional components and effects of the organic fertilizer, resulting in poor growth effects on the roots, stems, leaves, buds, fruits, etc. of crops.

[0056] 5) Tank-type animal protein organic fertilizer wet fermentation: Wet fermentation is carried out in 36 to 48 groups of vertical wet fermentation tanks 1.

[0057] 6) Dry-wet separation: After the wet fermentation, the organic fertilizer enters the dry-wet separator 34 for dehydration;

[0058] Dehydration is carried out using an inclined screen dry-wet separator. 8 to 10 inclined screen dry-wet separators are installed to control the odorous waste gas and odor in the room, where they are extracted by high-pressure exhaust fans and sent to a high-temperature incinerator for combustion.

[0059] 7) Second high-temperature drying: The dehydrated fertilizer enters the second set of high-temperature drying furnaces 35 for further drying.

[0060] Secondary dust removal and nitrogen, phosphorus, and potassium separation: Since wet fermentation fertilizer produces methane, odor, and waste gas, it undergoes purification and separation at 35°C in a second set of high-temperature drying furnaces to recover useful substances such as nitrogen, phosphorus, and potassium. A high-temperature incinerator processes the methane, odor, waste gas, odor, nitrogen, phosphorus, and potassium for another thorough adsorption, separation, and purification. The remaining airflow is dust-free, odorless, colorless, and harmless, meeting international, EU, and Chinese environmental emission standards.

[0061] 8) Cooling and thawing: The high-temperature fertilizer enters the cooling and thawing device 36 to cool down in order to facilitate subsequent continuous production operations.

[0062] 9) Quantitative preparation of multiple raw materials: The thawed fertilizer from the previous station is connected to the quantitative preparation of multiple raw materials mixing device 37, and then animal protein and 20 to 48 elements are added to mix according to the purpose and needs of the fertilizer. Therefore, it is most appropriate to choose to add protein and dozens of elements at this station, mainly avoiding two sets of high-temperature furnaces. At the same time, the design of this system also avoids the self-heating high temperature destruction of fertilizer organic matter in the traditional dry composting fermentation process. Therefore, this system can produce high-content animal protein organic fertilizer.

[0063] 10) Granulation: The fertilizer enters the granulator for granulation and shaping. After the granulation is finalized, it is transported to the packaging workshop for packaging.
