Description

Technical Field

[0001] The utility model belongs to the technical field of animal excrement treatment, and in particular relates to an environmentally friendly animal excrement treatment device. Background Art

[0002] The principles of animal manure treatment primarily include biodegradation, physical separation, and chemical treatment. Biodegradation utilizes microorganisms to break down organic matter in manure into simpler substances, such as carbon dioxide and water. Physical separation removes solid particles through solid-liquid separation techniques. Chemical treatment uses chemical agents to neutralize harmful components. Ultimately, treated manure can reduce environmental pollution, improve soil quality, or be converted into fertilizer for agricultural use. A wide variety of animal manure treatment equipment exists, with varying designs and functions tailored to different types of manure and treatment requirements. Commonly used systems include anaerobic digesters, aerobic composting systems, and wastewater treatment systems. Anaerobic digesters use anaerobic microorganisms to decompose organic matter in manure under anoxic conditions, producing biogas (primarily methane and carbon dioxide) and fertilizer residues. Under aerobic conditions, aerobic microorganisms decompose manure to produce compost. Regular turning of the manure is required to ensure an adequate oxygen supply. Wastewater treatment systems utilize physical, chemical, and biological methods to treat manure wastewater, including sedimentation, filtration, chemical flocculation, and activated sludge processes.

[0003] Existing animal manure treatment devices are prone to produce odor and harmful gases during the treatment process, polluting the environment. At the same time, the treatment efficiency is low and it is difficult to meet the needs of large-scale farming. Utility Model Content

[0054] 1. Biodegradation

[0055] Bioreactor Bed: The bioreactor bed inside the treatment tank processes animal waste through a biodegradation process. It consists of multiple biofilter discs coated with activated carbon granules and a porous filter layer. The activated carbon's strong adsorption capacity removes harmful substances from waste, while the porous filter layer further enhances treatment efficiency.

[0056] Biofilter discs: Filter discs are filled with activated carbon particles, which provide a large surface area for the attachment and growth of microorganisms. The microorganisms break down the organic matter in the manure and convert it into more harmless substances.

[0057] Porous filter layer: The filter layer is composed of a coconut husk layer, a vermicompost layer, and a nylon mesh, providing both mechanical filtration and biodegradation. The coconut husk and vermicompost layers help absorb and decompose organic matter, while the nylon mesh prevents larger solid matter from passing through.

[0058] 2. Gas processing and balance

[0059] Air pressure balance component: During the treatment process, a certain amount of gas will be generated in the treatment tank. The air pressure balance component is used to adjust the air pressure inside the treatment tank to ensure the stability of the treatment process.

[0060] Balancing valve: The spherical valve core of the balancing valve is wrapped with elastic material, which automatically adjusts the valve core position to maintain the internal air pressure. The spring between the valve core and the side wall of the balancing valve ensures that the valve core automatically adjusts when the air pressure changes.

[0061] Vent pipe: The vent pipe is used to transport the gas in the treatment tank to the balance tank to help gas discharge and air pressure balance.

[0062] 3. Use of detergent

[0063] Detergent: During the gas treatment process, a detergent is placed in the balance tank. This detergent further purifies the gas, removing any residual harmful substances. The detergent occupies half the volume of the balance tank, enhancing the gas purification effect.

[0064] 4. Mechanical separation and discharge

[0065] Discharge port: The treated manure is discharged from the treatment tank through the discharge port. The treated manure is usually further utilized or processed to achieve resource recovery.

[0066] Specifically, the principle of the present invention is: when in use, ensure that there is no debris in the treatment tank and its components, and clean them up. Connect the manure conveying system to the feed port of the treatment tank to ensure that the connection is stable and there is no air leakage. Input animal manure into the treatment tank through the feed port. The conveying speed and amount can be adjusted as needed to ensure that the amount of manure in the treatment tank is appropriate. The animal manure is treated by the reaction between the biological filter disc 62 and the animal manure, and the treated manure is discharged through the discharge port for subsequent use or treatment. During the treatment process, when the air pressure inside the treatment tank 10 is too high, the valve core of the balancing valve 52 is pushed to move toward the side of the vent pipe 53. When the valve core moves past the through-hole position, the gas enters the vent pipe 53 through the through-hole and enters the balancing tank. The valve core is restored to its original position by the action of the spring.
