[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0026] The utility model provides a device for composting test of high-moisture materials, such as Figures 1-6As shown, the apparatus comprises a base 1, with a drum 5 mounted above it. Two circular tracks 6 and a gear ring 4 are located outside the drum 5. Support wheels 8 are located below each of the circular tracks 6. A gear 3 is mounted on the outside of the gear ring 4, which is driven by a first motor 2. The gear 3 meshes with the outside of the gear ring 4, driving the gear ring 4 on the outside of the drum 5 to rotate. A second motor 10 is mounted above one end of the base 1. A central shaft 14 is mounted inside the drum 5, with spiral-shaped stirring blades 15 mounted on the outside of the central shaft 14. The central shaft 14 is driven by the second motor 10 to rotate. The drum 5 in the apparatus achieves stable rotational motion through the meshing of the gear ring 4 with the gear 3 and the drive of the first motor 2. Simultaneously, the central shaft 14 inside the drum 5 and the spiral stirring blades 15 on its outside, driven by the second motor 10, ensure thorough stirring and mixing of the compost material. This design not only enhances the material's tumbling and mixing effect but also promotes uniform distribution and sufficient contact of organic matter, thereby improving composting efficiency and quality. In addition, the arrangement of the two annular rails 6 and the supporting wheels 8 provides stable support and guidance for the roller 5, ensuring the stability and reliability of the device during long-term operation.

[0027] In this embodiment, a support rod is installed below the second motor 10 and fixed on the base 1 . The support wheel 8 is fixed on the base 1 through the frame 9 below, which facilitates the support and positioning of the second motor 10 .

[0028] Specifically, the output shaft of the first motor 2 rotates in the opposite direction to the output shaft of the second motor 10 to enhance the turning and mixing effect of the materials in the drum and promote the uniform distribution and full contact of the organic matter.

[0029] Furthermore, the wall of the drum 5 has a three-layer structure, the innermost layer is the inner mesh steel plate 13, the middle layer is the e-PTFE membrane layer 12, and the outermost layer is the outer mesh steel plate 11. The e-PTFE membrane layer 12 has excellent air permeability and waterproof properties, and can prevent external moisture from entering while maintaining the air permeability of the compost material and the dissipation of water vapor. The e-PTFE membrane is an intelligent molecular membrane material that can automatically adjust the pore size according to the changes in gas pressure generated by microbial activity to ensure a uniform and sufficient supply of oxygen throughout the tank. The application of this material effectively promotes the decomposition and transformation of organic matter, accelerates the composting process, and reduces the generation of odor. The purpose of the design of sandwiching an e-PTFE membrane between the double-layer mesh steel plate is, on the one hand, to give full play to the efficacy of the e-PTFE membrane, to ensure the air permeability and water vapor evaporation of the high-moisture material compost, and to ensure the oxygen supply during the microbial fermentation process. On the other hand, it plays the role of supporting the tank body, because the e-PTFE membrane cannot be used alone to support the tank body.

[0030] During operation, regularly check the integrity of the e-PTFE membrane to ensure its breathability is intact. Ensure that the material is evenly distributed within the drum to avoid incomplete mixing due to uneven accumulation. Adjust the motor operating parameters appropriately based on the characteristics of the composting material and test requirements to achieve optimal composting results. During the composting process, closely monitor changes in material temperature and humidity, making timely adjustments to prevent excessive humidity from affecting microbial activity.

[0031] Regularly check the lubrication of the motor system and bearings to ensure smooth operation. If the e-PTFE membrane is damaged, replace it immediately to avoid affecting the composting effect.

[0032] Furthermore, an inlet and outlet port 7 is provided at one end of the drum 5 away from the second motor 10, and a cover plate is hinged on the inlet and outlet port 7 to prevent the material from spilling out during the composting operation of the device. A detection port 16 is provided on the cover plate for detecting temperature and humidity and sampling the compost material.

[0033] Furthermore, a temperature and humidity sensor and a material sampling spoon are installed inside the detection port 16 for real-time monitoring of the temperature and humidity of the compost material.

[0034] Furthermore, there is an angle of 5° between the drum 5 and the base 1, so that during the rotation of the material in the drum, due to the action of gravity, it gradually moves to the lower side, thereby achieving effective discharge of the material.

[0035] Furthermore, the outer wall of the annular track 6 is provided with an annular track groove 61, and the track groove 61 is adapted to the size of the support wheel 8. The inner wall of the annular track 6 is installed with four threaded holes 62, and a locking pin 63 is installed in the threaded hole 62. The outer wall of the locking pin 63 is provided with an external thread, and the locking pin 63 is threadedly connected to the threaded hole 62. The outer wall of the outer mesh steel plate 11 is provided with a pin hole 111 near the locking pin 63. The end of the locking pin 63 is plugged into the pin hole 111, which is convenient for locking and fixing the annular track 6 on the outer wall of the cylinder 5, and is convenient for disassembly and maintenance and repair at any time.

[0036] When using the device for composting high-moisture materials of the present invention, the first motor 2 is first activated, driving the gear 3 to rotate. Because the gear 3 is meshed with the outer ring gear 4, the rotation of the gear 3 drives the ring gear 4 on the outer side of the upper drum 5 to rotate, thereby achieving stable rotational motion of the drum 5 as a whole. Simultaneously, the second motor 10 is also activated, driving the central shaft 14 and its external spiral stirring blades 15 to rotate. In this way, the compost material in the drum 5 is not only turned over as the drum 5 rotates, but is also thoroughly stirred and mixed by the spiral stirring blades 15, thereby enhancing the turning and mixing effect of the material and promoting the uniform distribution and sufficient contact of the organic matter.

[0037] The three-layer structure of drum 5 plays a key role in the composting process. The e-PTFE membrane 12, with its excellent air permeability and waterproof properties, maintains the compost's breathability, allowing water vapor to escape while preventing external moisture from entering, creating an ideal fermentation environment.

[0038] To monitor the temperature and humidity of the composting process, a detection port 16 is provided on the cover plate of the inlet and outlet 7, and a temperature and humidity sensor and a material sampling spoon are installed. This allows the operator to monitor the temperature and humidity of the composting material in real time and take samples for analysis using the material sampling spoon.

[0039] When the composting process is completed and the material needs to be discharged, the 5° angle between the drum 5 and the base 1 can be utilized. During the rotation of the drum 5, due to the component of gravity, the material will gradually move to the lower side, thereby achieving effective discharge of the material.

[0040] Furthermore, the arrangement of the annular track 6 and the supporting wheels 8 not only provides stable support and guidance for the drum 5, but also secures the annular track 6 to the outer wall of the drum 5 through the cooperation of the locking pin 63 and the pin hole 111. Furthermore, this design facilitates removal for maintenance and repair at any time, improving the ease of use and maintenance efficiency of the device.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
