Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and biomass resource utilization technology, specifically relating to an equipment suitable for the treatment of organic solid waste in urban and rural areas.

[0002] More specifically, this invention relates to an intelligent organic fertilizer manufacturing equipment that integrates the processing functions of household waste, agricultural straw, and garden waste. This equipment relies on integrated technologies of high-temperature molding pyrolysis, in-situ biochar molding, intelligent batching, and scientific formulation. Through a high-temperature, high-pressure mechanochemical conversion process, it directly transforms complex organic solid waste into biochar-based organic fertilizer in a one-step process. This specialized manufacturing system deeply integrates advanced formulation systems and digital control systems, enabling continuous, intelligent, low-energy-consumption, and pollution-free production across the entire chain from raw material input to functional organic fertilizer output. It is widely applicable in important fields such as saline-alkali land improvement, soil fertility enhancement, and ecological agriculture construction. Background Technology

[0003] (I) The Dilemma of Traditional Processing Methods

[0004] For a long time, straw treatment methods have been relatively limited, mainly consisting of burning, returning to the field, or simple composting. Burning straw causes serious environmental pollution; while returning to the field and composting have drawbacks such as long decomposition cycles and low nutrient utilization rates, making it difficult to achieve high-value utilization of straw. Although biochar technology has certain advantages, traditional straw charcoal production processes are cumbersome, energy-intensive, and highly polluting, and the separation of "carbonization" and "fertilization" prevents the full realization of the agricultural value of straw.

[0005] (II) Pain Points in Municipal Solid Waste Disposal

[0006] The treatment of municipal solid waste (especially food waste) faces enormous challenges. Traditional landfilling consumes vast amounts of land resources; incineration easily produces harmful substances such as dioxins and incurs huge investment costs; existing biological treatment methods suffer from long processing cycles and high levels of impurities in the products. Furthermore, municipal solid waste has a complex composition, often containing high concentrations of salt, free grease, sand, and metals. Without thorough pretreatment, downstream equipment is easily damaged, reducing processing efficiency.

[0007] (III) Defects of Existing Equipment

[0008] Entanglement and blockage: Plastics, fibers and other materials in household waste can easily become entangled in equipment, causing equipment shutdown and affecting normal production.

[0009] Corrosion and coking: The salt in the waste can not only cause soil compaction, but also corrode the equipment; grease can coke at high temperatures, causing the pyrolysis furnace to become blocked (seize), which seriously affects the normal operation of the equipment.

[0010] Incomplete dehydration: Traditional roller extrusion methods are ineffective at dehydrating viscous and fibrous waste, resulting in high load and energy consumption in subsequent processing.

[0011] Limited functionality: Existing equipment cannot effectively process mixed waste, making it difficult to solve the practical problem of "separating it is useless", and failing to meet the needs of complex organic solid waste treatment.

[0012] (iv) Breakthrough of the present invention

[0013] To address the shortcomings of traditional equipment, this invention innovatively proposes a four-in-one intelligent manufacturing system integrating crushing, impurity removal, carbonization, and fertilizer production. This invention abandons the simple "physical sorting" model and, by introducing efficient spiral extrusion dehydration technology and high-temperature molding pyrolysis technology, directly transforms complex organic waste into high-value biochar, fundamentally solving the industry pain point of "sorted waste being useless." Summary of the Invention

[0014] (I) Purpose of the Invention

[0015] This invention aims to develop a compact and functionally integrated intelligent manufacturing equipment for biochar-based organic fertilizer, enabling continuous, low-energy, clean, and intelligent one-step production of functional organic fertilizer from complex municipal solid waste and agricultural waste. Specifically, it addresses the removal of grease, soil, sand, salt, and metallic impurities from mixed materials, improving the system's adaptability to complex raw materials and providing an effective approach for the efficient treatment and resource utilization of organic solid waste.

[0016] (II) Technical Solution

[0017] 1. The first pretreatment system (integrated automatic segmentation and spiral dehydration separation unit) – the core defense line

[0018] (1) This system can use excavators and loaders to crush garbage, waste materials and straw and pour them directly into the distribution bin. Figure 1 As shown, the feeder can evenly distribute the feed into the hopper of the screw extruder. Figure 2-5 As shown, the screw extruder dewatering machine powerfully compresses the material. Figure 2 As shown, this device uses a spiral structure to compress materials in stages, which can completely separate and discharge the water and free liquid in the materials. The separated liquid flows into a liquid collection tank through a drain pipe. Figure 2-8 As shown, solid-liquid separation was achieved.

[0019] (2) Grease recovery: The squeezed liquid contains free grease, and the liquid collection tank is equipped with a discharge gate; when the grease reaches a certain level, the water is released from the gate. Figure 10As shown, after sedimentation and separation, it can be sold as industrial crude oil, realizing the resource utilization of oil and creating additional economic value.

[0020] (3) Magnetic removal of impurities: The solid material is crushed by a fully automatic crusher. With the help of the built-in stirring device and screening mechanism, the heavy impurities such as mud and sand attached to the material are effectively separated from the organic material and filtered out to the magnetic conveyor belt. The magnetic force is used to adsorb the metal substances mixed in onto the cover belt. A scraper is provided behind the cover belt to scrape the metal into the collection device, realizing the effective recycling of waste metal and improving the purity of the material.

[0021] (4) Drying: The cleaned material after the above treatment is directly fed into the microwave oven hopper, and the microwave oven ( Figure 3 As shown, the material is dried until it turns yellowish-brown, and then directly sent to the second process.

[0022] 2. The second integrated biochar product manufacturing machine (high-temperature molding pyrolysis and forming unit) – core reactor

[0023] This unit is a key piece of equipment for converting organic solid waste into biochar. Its core lies in using rapid mechanical rotation and variable torque friction to achieve instantaneous pyrolysis and densification of materials in an oxygen-deficient environment.

[0024] (1) Feeding and pre-compression: When the material arrives at the feed box, it is first subjected to preliminary twisting, friction and compaction by the roller extruder, and then enters the core carbonization zone.

[0025] (2) Key design logic: Since the front-end spiral extrusion has fully squeezed out the oil and water or liquid, the material entering this system is a dry and pure solid, which provides good conditions for efficient carbonization.

[0026] (3) Power and transmission system of the whole machine: The main machine is equipped with a high-efficiency energy-saving motor of 40-60 kW, which drives the main shaft through a hardened gear reducer and coupling to ensure stability under high torque output.

[0027] (4) Core cavity structure: The main body of the equipment is a high-strength welded steel structure or a conical cavity formed by a mold. The total length of this conical cavity is 230-270 cm. Figure 7 As shown, its inner diameter is tapered, with an inlet diameter of 63-73 cm. Figure 7-2 The display shows that the outlet diameter has been reduced to 19-22 cm. Within the cavity's sandwich structure, a cooling water channel winds around every 10 cm. Figure 4-6 The display shows that the cavity has an inlet and an outlet at both ends. Figure 4-5 As shown in Figure 7, the temperature of the outer wall of the cavity is controlled by circulating cold water to prevent excessive heat loss and protect the equipment casing.

[0028] (5) Core actuator (auger shaft system): Built-in hollow auger shaft with an inner diameter of 5-10 cm. Figure 8-3 The hollow shaft not only serves as a torque transmission component, but also has an internal circulating cooling water channel. Figure 9-4 The display screen is designed to reduce the temperature of the shaft and auger, enhance the toughness of the metal material under high-temperature conditions, and prevent deformation. The auger blades are coiled around the shaft in a conical structure that matches the cavity, with a large-end diameter of 60-69 cm. Figure 9-2 The small end diameter is shown to be 19-25 cm. Figure 9-3 The blade wall thickness is shown to be 2-4 cm (9-5).

[0029] (6) Precision fit and pyrolysis mechanism: The outer edge of the conical auger blades maintains a very small gap of about 2 mm with the inner wall of the conical cavity, forming a tight grinding mechanism. Under the strong propulsion of the power system, the material is squeezed tighter and tighter as the cavity volume decreases. Intense friction is generated between the material, the auger and the cavity, generating high-temperature heat energy. Combined with the internal oxygen-deficient environment, the material is rapidly heated to 260-500℃.

[0030] (7) Temperature control and material properties: The equipment is equipped with an infrared automatic sensing system to monitor and automatically control the internal temperature of the chamber in real time, keeping it stable within the optimal pyrolysis range of 300-400℃. Both the conical chamber and the conical auger are made of high-quality high-manganese steel (GB / T5680-2010, based on ZGMn13 grade) thick-walled material. Utilizing the wear resistance and toughness of manganese steel at high temperatures, it ensures that the material is ultimately transformed into high-density, high-carbon-content biochar particles at the outlet.

[0031] (8) In-situ forming mechanism: A circular die forming device is provided at the equipment outlet. The circular hole in the middle of the die holder is 2 mm larger than the diameter of the auger shaft. The die holder is installed at the outlet of the conical cavity. Figure 4-8 The cutter is shown to be fixed on the shaft. Figure 4-9 The display shows that as the auger rotates, the extruded cylindrical carbon strips are cut into cylindrical particles of approximately 3 mm in diameter, which are then conveyed to the subsequent batching system via a second cooling channel. (Note: All components of this equipment are manufactured using high-tech, large-scale steel structure molds.)

[0032] 3. Batching and Pelletizing System

[0033] In subsequent processing, the biochar granules are cooled by a conveyor, reaching a temperature of approximately 80℃ upon arrival at the mixing tank. Simultaneously, based on the organic fertilizer formula, the following components are precisely mixed using a digital system: biochar 25-30%; volcanic rock microparticles 15-20%; humic acid powder 10-15%; phosphogypsum powder 10-15%; sesame oil residue and soybean cake fragments 10-15%; gypsum and phosphogypsum powder 10-15%; sulfur powder 1-3%; ferrous sulfate 1-2%; and trace elements 0.5-1%.

[0034] These components are mixed in the mixing tank. Wood vinegar is evenly sprayed onto the material using a digital sprayer. After thorough mixing in the mixer, the material enters the pellet mill hopper.

[0035] The above components are precisely metered using an intelligent batching system and thoroughly mixed with biochar granules in a cylindrical mixer. During granulation, the equipment monitors the material status in real time using temperature sensors to ensure the mixture completes bonding and molding within the 60-70℃ range, avoiding nutrient loss due to high temperatures and ensuring fertilizer quality. The mixture is then sequentially shaped into 3-5 mm spherical granules using a die. After cooling, an automatic packaging system automatically weighs and seals the granules, and the finished product is transported to the warehouse via a conveyor.

[0045] (9) Wood vinegar (0.5-1.5%): It is an acidic organic mixture produced by the pyrolysis of plant materials. It is miscible with water and has antibacterial and antiseptic properties. It has certain effects in agriculture, environmental protection and medicine, and provides health protection for plant growth.
