Description

Technical Field

[0001] The utility model belongs to the technical field of fermentation equipment, and specifically relates to an organic fertilizer fermentation equipment, and in particular to an organic solid waste and carbon-based material co-fermentation equipment. Background Art

[0002] The resource utilization of agricultural waste can transform "waste" into "resources," effectively reducing its negative impact on the ecological environment and playing a vital role in achieving sustainable agricultural development. Therefore, the resource utilization of agricultural waste is undoubtedly a necessary step in promoting sustainable agricultural development. This process is crucial for reducing the impact of agricultural production on the environment and achieving sustainable agricultural development.

[0003] Composting utilizes microorganisms to biodegrade and transform livestock and poultry manure. Through this controlled aerobic fermentation process, a loose material rich in humus is produced, which can be used as soil improvement or organic fertilizer. Composting is a viable, economical, and environmentally friendly option for treating livestock and poultry manure. It has been widely used to treat decomposable urban garbage, crop straw, and other organic solid waste, reducing waste and achieving resource utilization and harmlessness.

[0004] When aerobic composting livestock and poultry manure, organic additives such as straw, sawdust, and mushroom residue are often added to reduce gas loss during composting while retaining nutrients. These additives can regulate the compost substrate's moisture content, pH, temperature, aeration, and nutrient content, thereby achieving nutrient retention while reducing harmful gas emissions. Additives are widely used in composting to reduce emissions and promote composting. Additives can be divided into three categories based on their properties and the mechanism of action during the composting process: physical additives, chemical additives, and microbial additives. Common physical additives are mainly carbon-based materials, including biochar and activated carbon. These additives improve the physical properties of the compost, such as increasing water retention, aeration, and adsorption capacity, thereby optimizing the overall composting environment and promoting the decomposition and conversion of organic matter. The appropriate application of these carbon-based additives can significantly improve the quality of the compost product and enhance the efficiency of the composting process.

[0005] At present, people mainly return feces directly to the fields and discard organic solid waste such as garden pruning branches and leaves, wood chips, and mushroom residues as garbage. There are no literature reports on mixing these organic solid wastes with carbon-based materials for co-fermentation to prepare fertilizers, and there is no equipment on the market that uses mixed organic solid wastes and carbon-based materials for co-fermentation.

The rising rate of the heap temperature and the regulation and maintenance time length of the heap temperature are important indexes for evaluating the composting quality. The regulation of the heap temperature is inseparable from the mixing of the materials. Compared with the prior art, the organic solid waste and carbon-based material co-fermentation equipment has the following beneficial effects:

The transmission pipe 6 corresponding to the spreading mechanism 9 and the tank body 1 are provided with a stirring mechanism 10. The lower surface of the transmission pipe 6 is connected to the rotating pipe 12 through a transmission mechanism 11, and the rotating pipe 12 is installed on the lower inner wall of the tank body 1 through a first bearing assembly 13. The rotating pipe 12 is provided with a distribution mechanism 14 near the upper and lower positions, and the rotating pipe 12 corresponding to the stirring mechanism 10 is provided with a sealing mechanism 15.

[0026] Specifically, mechanical seals 16 are provided on the upper sidewall of the tank 1 and the upper and lower sidewalls of the box 4 corresponding to the transmission pipe 6. In this embodiment, the mechanical seals 16 provide a better sealing effect between the transmission pipe 6 and the upper sidewall of the tank 1 and the upper and lower sidewalls of the box 4.

[0027] Specifically, the spreading mechanism 9 includes a diversion hopper 901 and a spreading tray 902. The diversion hopper 901 is fixedly mounted on the lower surface of the sealing cover 2, and the spreading tray 902 is fixedly mounted on the transmission pipe 6 below the diversion hopper 901. In this embodiment, the diversion hopper 901 directs the material to flow toward the spreading tray 902, which rotates with the transmission pipe 6 and spreads the material within the tank body 1.

[0028] Specifically, the stirring mechanism 10 includes stirring blades 101, an electric telescopic rod 102, and a conical bucket 103. The stirring blades 101 are fixedly mounted on the left and right sides of the transmission tube 6. The electric telescopic rod 102 is evenly mounted along the circumference of the inner wall of the tank body 1. The conical bucket 103 is fixedly mounted between the upper surfaces of the output shafts of the electric telescopic rod 102. In this embodiment, the stirring blades 101 rotate with the transmission tube 6, stirring the material on the upper surface of the conical bucket 103. At the same time, the electric telescopic rod 102 drives the material on the upper surface of the conical bucket 103 to move up and down within a small range, so that the material is fully stirred by the stirring blades 101. When the conical bucket 103 is far away from the sealing mechanism 15, the material on the conical bucket 103 falls into the lower side of the tank body 1, which can better promote composting and fermentation.

[0029] Specifically, the transmission mechanism 11 includes a rectangular tube 111, a slot 112, and a sealing ring 113. The rectangular tube 111 is fixedly mounted on the lower surface of the transmission tube 6. The rotating tube 12 corresponding to the rectangular tube 111 has a slot 112 formed therein, and the rectangular tube 111 is inserted into the slot 112. The sealing ring 113 is fixedly mounted on the outer surface of the rectangular tube 111. In this embodiment, the rectangular tube 111 is inserted into the slot 112 in the rotating tube 12, so that the transmission tube 6 drives the rotating tube 12 to rotate through the rectangular tube 111. The sealing ring 113 provides a better sealing effect between the transmission tube 6 and the rotating tube 12.

[0030] Specifically, the distribution mechanism 14 includes a distribution tube 141 and a discharge hole 142. The distribution tube 141 is fixedly mounted on the outer surface of the rotating tube 12, and the discharge holes 142 are formed on the front and rear sides of the distribution tube 141. In this embodiment, the microbial agent or air flows into the distribution tube 141 and then flows out through the discharge hole 142, ensuring that the agent or air flows evenly into the material.

[0031] Specifically, the sealing mechanism 15 includes a second bearing assembly 151 and a sealing cylinder 152. The second bearing assembly 151 is fixedly mounted on the rotating tube 12. The sealing cylinder 152 is fixedly mounted on the upper surface of the second bearing assembly 151. The upper surface of the sealing cylinder 152 contacts the lower surface of the conical bucket 103. In this embodiment, the second bearing assembly 151 satisfies the rotation requirements of the sealing cylinder 152, allowing the sealing cylinder 152 to better seal the lower surface of the conical bucket 103. A through hole is formed in the sealing cylinder 152 at a position corresponding to the rotating tube 12.

[0032] During use, the staff opens the upper cover of the feeding pipe 3 of the equipment of the utility model, and pours organic solid waste, straw and other auxiliary materials and carbon-based materials (biochar) into the tank body 1 through the three feeding pipes 3. At this time, the output shaft of the motor 5 drives the transmission pipe 6 to rotate, and the material falls on the spreading plate 902 through the guide bucket 901 in the spreading mechanism 9. The spreading plate 902 rotates with the transmission pipe 6, and the spreading plate 902 spreads the material in the tank body 1, so that the multiple materials are evenly dispersed in the tank body 1. At the same time, the transmission pipe 6 drives the stirring blade 101 in the stirring mechanism 10 to rotate to stir the material. At the same time, the output shaft of the electric telescopic rod 102 drives the conical bucket 103 to move back and forth up and down. At this time, the conical bucket 103 will not separate from the sealing cylinder 152, and the material will not fall down, so that the conical bucket 103 drives the material to move up and down, and the stirring blade 101 can fully stir the material, which is beneficial to subsequent stirring and mixing. After the stirring is completed, the electric telescopic rod 102 drives the conical bucket 103 to move to the uppermost side. At this time, the conical bucket 103 is separated from the sealing cylinder 152 in the sealing mechanism 15, and the material will fall on the lower side of the tank body 1. The transmission tube 6 drives the rotating tube 12 to rotate in the first bearing assembly 13 through the transmission mechanism 11, and the rotating tube 12 drives the distribution tube 141 in the distribution mechanism 14 to rotate, so that the material can be evenly distributed on the lower side of the tank body 1.

[0033] When it is necessary to add microbial agents to the material or to introduce air, the connecting pipe 8 is connected to the water pump and the fan. The microbial agents or air enter the box body 4, flow into the transmission pipe 6 through the feed hole 7, and then flow into the rotating pipe 12 through the transmission mechanism 11 on the lower surface of the transmission pipe 6, flow into the distribution pipe 141 through the rotating pipe 12, and then flow in through the discharge hole 142. The inflowing microbial agents and air are evenly dispersed and can fully react with the raw and auxiliary materials on the lower side of the tank body 1, thereby improving the composting fermentation efficiency.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
