Detailed Implementation

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Example 1

[0026] Please see Figure 1-5As shown, a sheep manure organic fertilizer fermentation tank of this embodiment includes an outer tank 2 and a fermentation tank 1 disposed inside the outer tank 2. The outer tank 2 has a heating cavity 11 that runs through the top of the outer tank 2. The top of the outer tank 2 is detachably connected to a top ring plate 12. The top of the top ring plate 12 is connected to a plurality of heating structures disposed inside the heating cavity 11. A liquid inlet pipe 6 is connected to one side of the top of the top ring plate 12. A liquid outlet pipe 5 is connected to one side of the bottom of the outer tank 2. A base 3 is connected to the bottom of the outer tank 2. A discharge pipe 4 is connected to one side of the bottom of the outer tank 2. The top of the discharge pipe 4 communicates with the interior of the fermentation tank 1.

[0027] The workflow is as follows: During use, the sheep manure raw material to be fermented enters the internal fermentation tank 1 through the feed inlet. Then, the heating structure is activated. This heating structure is located on top of the top ring plate 12 and in the heating cavity 11 inside the outer tank 2. Through heat conduction within the heating cavity 11, heat is evenly transferred to the interlayer area between the outer tank 2 and the fermentation tank 1, thereby indirectly heating the material inside the fermentation tank 1. During this process, the heat generated by the heating structure does not directly contact the material or the inner wall of the tank, avoiding material damage caused by localized high temperatures. At the same time, the top of the outer tank 2 is equipped with a liquid inlet pipe 6 for injecting heat-conducting medium or cleaning liquid into the heating cavity 11, and a liquid drain pipe 5 is located on one side of the bottom for draining the used liquid, maintaining the stability of the system circulation. After fermentation, the finished organic fertilizer is discharged through the discharge pipe 4. The top of the discharge pipe 4 is connected to the inside of the fermentation tank 1 to ensure thorough discharge. The entire equipment is supported by the base 3, making the structure stable. The top ring plate 12 is detachably connected to the top of the outer tank 2 for easy maintenance and replacement of the heating structure.

[0028] Example 2

[0029] Please see Figure 1-5 As shown in the figure, in this embodiment of a sheep manure organic fertilizer fermentation tank, the top ring plate 12 has several through holes. The heating structure includes a mounting base 18 and a heating pipe 14 connected to the bottom of the mounting base 18. One end of the heating pipe 14 extends through the through holes into the interior of the heating cavity 11. Specifically, through the several through holes on the top ring plate 12 and the cooperation between the mounting base 18 and the heating pipe 14 in the heating structure, during operation, the bottom of the heating pipe 14 passes through the through holes into the heating cavity 11, and heat is transferred in the interlayer between the outer tank 2 and the fermentation tank 1. This achieves uniform indirect heating of the material inside the fermentation tank, thereby improving heating uniformity, avoiding damage to the equipment from local high temperatures, and enhancing the stability and safety of the fermentation process.

[0030] Side plates 17 are fixedly connected to both sides of the mounting base 18. A round hole is opened at the top of the side plate 17, and a positioning screw 19 connected to the top of the top ring plate 12 is set inside the round hole. A positioning nut is connected to the top of the positioning screw 19. Specifically, through the cooperation of the side plates 17 fixedly connected to both sides of the mounting base 18, the round hole opened at the top of the side plate 17, the positioning screw 19 and the positioning nut, the heating tube 14 can be firmly fixed to the top ring plate 12 during the installation of the heating structure, and can be quickly disassembled and replaced as needed. This achieves the effect of improving the installation stability and maintenance convenience of the heating structure, and ensuring long-term operational reliability.

[0031] The bottom of the top ring plate 12 is fixedly connected to a sealing ring plate 13 that is adapted to the top of the opening. The top ring plate 12 is made of metal. Specifically, the sealing ring plate 13 fixedly connected to the bottom of the top ring plate 12 is adapted to the opening of the heating cavity 11, and the top ring plate 12 is made of metal. During equipment operation, the sealing ring plate 13 effectively seals the top opening of the heating cavity 11, preventing the heat transfer medium from overflowing or impurities from entering. At the same time, the metal material improves the structural strength and high temperature resistance, thereby enhancing the equipment's sealing performance and extending its service life.

[0032] Example 3

[0033] Please see Figure 1-5 As shown in the figure, this embodiment of a sheep manure organic fertilizer fermentation tank has a top cover 8 connected to the top of the fermentation tank 1. A stirring rod 10 is installed inside the fermentation tank 1. A drive motor 9 for driving the stirring rod 10 to rotate is installed on the top of the top cover 8. A feed pipe 7 is connected to one side of the top of the top cover 8. Specifically, through the top cover 8 connected to the top of the fermentation tank 1, the stirring rod 10 installed inside, the drive motor 9 installed on the top of the top cover 8, and the feed pipe 7, after the sheep manure material enters the fermentation tank 1, the drive motor 9 drives the stirring rod 10 to rotate, so that the material is fully mixed and evenly heated. At the same time, nutrient solution is added or humidity is adjusted through the feed pipe 7, thereby improving the fermentation efficiency and the homogenization of the material, and enhancing the quality of the finished organic fertilizer.

[0034] A top positioning plate 16 is connected to the top side of the top ring plate 12, and a bottom positioning plate 15 is connected to the bottom side. The top positioning plate 16 is bolted to the side wall of the fermentation tank 1, and the bottom positioning plate 15 is bolted to the side wall of the outer tank 2. Specifically, by setting the top positioning plate 16 connected to the top side of the top ring plate 12 to the side wall of the fermentation tank 1 and the bottom positioning plate 15 connected to the bottom side to the side wall of the outer tank 2, the top ring plate 12 can be accurately positioned and stably connected to the fermentation tank 1 and the outer tank 2 during the assembly process. This achieves the effect of enhancing the overall structural stability and sealing performance, and preventing displacement or leakage during operation.

[0035] The length of the heating tube 14 is less than the length of the heating cavity, and the diameter of the heating tube 14 is less than the internal width of the heating cavity. The top cover 8 is bolted to the top of the fermenter 1, and the diameter of the top cover 8 is the same as the top diameter of the fermenter 1. The thickness of the side plate 17 is less than the height of the mounting base 18, and the side plate 17 is made of metal. Several top positioning plates 16 and several bottom positioning plates 15 are provided, and the several top positioning plates 16 and several bottom positioning plates 15 are arranged in a ring along the circumference of the top ring plate 12.

[0036] The overall structure of this sheep manure organic fertilizer fermentation tank includes an outer tank 2, a fermentation tank 1 set inside the outer tank 2, a heating cavity 11, a top ring plate 12, a heating structure, an inlet pipe 6, a drain pipe 5, a base 3, a discharge pipe 4, a top cover 8, a stirring rod 10, a drive motor 9, a feed pipe 7, a mounting base 18, a heating pipe 14, a side plate 17, a positioning screw 19, a positioning nut, a top positioning plate 16, a bottom positioning plate 15, a sealing ring plate 13, and other key components. In actual operation, the sheep manure raw material to be processed enters the fermentation tank 1 through the feed pipe 7, and then the heating structure is activated. This heating structure consists of a mounting base 18 and a heating pipe 14 connected to its bottom. One end of the heating pipe 14 passes through a through hole on the top ring plate 12 and extends into the heating cavity 11. Through heat conduction, heat is evenly transferred to the interlayer area between the outer tank 2 and the fermentation tank 1, achieving indirect heating of the material. At the same time, the top of the outer tank 2 is equipped with a liquid inlet pipe 6 for injecting heat-conducting medium or cleaning liquid into the heating cavity 11, and the bottom is equipped with a liquid drain pipe 5 for discharging the used liquid, ensuring stable system circulation. After fermentation, the finished organic fertilizer is discharged through the discharge pipe 4. The top of the discharge pipe 4 is connected to the inside of the fermentation tank 1 to ensure thorough discharge without residue. To improve fermentation efficiency and material mixing uniformity, The fermenter 1 is connected to a top cover 8, on which a drive motor 9 is installed to rotate the stirring rod 10, so that the material is fully mixed and heated evenly. In addition, the mounting base 18 in the heating structure is fixedly connected to two side plates 17 on both sides. The top of the side plates 17 has a round hole, which, together with the positioning screw 19 and the positioning nut, enables the heating tube 14 to be securely installed and quickly disassembled for maintenance. The top ring plate 12 is connected to a top positioning plate 16 on one side of the top and a bottom positioning plate 15 on the bottom side, which are fixed to the side walls of the fermenter 1 and the outer tank 2 respectively with bolts, enhancing the stability and sealing of the overall structure. The bottom of the top ring plate 12 is also fixedly connected to a sealing ring plate 13, which is used to seal the top opening of the heating cavity 11 to prevent the heat transfer medium from leaking or impurities from entering. The entire top ring plate 12 is made of metal, which improves its high temperature resistance and structural strength.

[0037] This fermenter addresses a core problem in existing technologies—namely, the heating structure of traditional fermenters is directly located inside the tank, leading to uneven local heating, material fatigue deformation, and even corrosion, which affects the service life and safety of the equipment. By moving the heating structure into the heating cavity 11 and adopting an indirect heating method, direct contact between the heating element and the material or the inner wall of the fermenter 1 is avoided, significantly improving heating uniformity and temperature control accuracy, and extending the service life of the equipment. The heating structure consists of a mounting base 18 and a heating tube 14, which are installed in conjunction with the through holes on the top ring plate 12, facilitating later maintenance and replacement and enhancing the maintainability of the equipment. At the same time, the cooperation of the side plate 17, the positioning screw 19 and the positioning nut improves the installation stability and ease of disassembly of the heating structure. The design of the top positioning plate 16 and the bottom positioning plate 15 achieves precise positioning and firm connection between the top ring plate 12 and the fermenter 1 and the outer tank 2, ensuring structural stability and sealing performance during equipment operation. The setting of the sealing ring plate 13 effectively prevents the overflow of the heat transfer medium and improves the safety of equipment operation. The combination of the stirring rod 10 and the drive motor 9 further improves the uniformity of material mixing, increases fermentation efficiency and product quality.
