Description

Technical Field

[0001] The invention particularly relates to a feces composting biodegradation dehydration granulation device. Background Art

[0002] Livestock and poultry manure mainly refers to a type of rural solid waste generated in the livestock and poultry breeding industry, including pig manure, cow manure, sheep manure, chicken manure, duck manure, etc. Anaerobic fermentation: Under anaerobic or anaerobic conditions, the composting process is mainly carried out by anaerobic microorganisms. The final product includes humus organic matter, carbon dioxide and methane, as well as reducing substances such as ammonia, hydrogen sulfide and other organic acids; however, the existing devices in this field have the problem of low efficiency and low practicality. Therefore, a manure composting biodegradation dehydration granulation device is proposed to solve the above problems. Summary of the invention

[0003] The object of the present invention is to provide a feces composting biodegradation dehydration granulation device in view of the deficiencies of the prior art, and the feces composting biodegradation dehydration granulation device can well solve the above problems.

[0004] In order to achieve the above requirements, the technical solution adopted by the present invention is: to provide a feces composting biodegradation dehydration granulation device, the feces composting biodegradation dehydration granulation device comprises the following modules:

[0005] The manure receiving and processing unit is used to receive and store manure unloaded from the manure transport vehicle, and to remove large solid particles and some organic matter in the manure by crushing and washing to prepare for subsequent processing;

[0006] The solid-liquid separation unit is used to effectively separate the solid and liquid in the feces, facilitate the subsequent biodegradation and dehydration treatment, reduce the volume of the solid part, and reduce the difficulty and cost of subsequent treatment;

[0007] The biodegradation unit uses the decomposition of microorganisms to convert organic matter in feces into harmless substances, and ensures the uniformity and efficiency of the degradation process through a stirring and temperature control system;

[0008] The dehydration unit is used to further remove moisture from solid materials, increase the moisture content of fertilizers, and provide a suitable material state for subsequent granulation processing;

[0009] The granulation unit is used to process the dehydrated solid materials into granular fertilizers, which are convenient for storage, transportation and use, and improve the commercial quality of the fertilizers.

[0010] The advantages of the feces composting biodegradation dehydration granulation device are as follows:

[0011] Environmental pollution: Traditional feces treatment methods often lead to environmental pollution, especially the direct discharge or stacking of untreated feces will produce odor and harmful substances. This device achieves harmless treatment and resource utilization of feces through biodegradation and dehydration granulation process, effectively solving the problem of environmental pollution.

[0012] Waste of resources: Feces are rich in organic matter and nutrients (such as nitrogen, phosphorus, potassium, etc.), and direct discharge or inefficient use is a huge waste of resources. This device converts feces into organic fertilizer, improving resource utilization and added value.

[0013] Low processing efficiency: Traditional feces processing methods usually require a long time and cumbersome operating steps, and the processing effect is unstable. This device greatly improves the processing efficiency and stability through automated and efficient processing processes, reducing manual intervention and costs.

[0014] Wide applicability: The device is not only suitable for large-scale feces sources such as farms, but also for urban garbage disposal, rural domestic sewage treatment and other fields. It has wide applicability and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
