Description

Technical Field

[0001] This invention relates to the field of environmental protection and resource recycling technology, specifically to a high-efficiency vertical high-temperature aerobic fermentation device. Background Technology

[0002] In the field of environmental protection and resource recycling, high-temperature aerobic fermentation technology is one of the key technologies for treating organic waste such as livestock and poultry manure, kitchen waste, and agricultural straw. With the rapid development of my country's livestock and catering industries, the output of organic waste has increased significantly. Improper treatment not only causes soil and water pollution but also wastes the recyclable resources contained within. High-temperature aerobic fermentation technology transforms organic waste into high-quality organic fertilizer through the metabolic action of microorganisms in a high-temperature, aerobic environment, achieving "turning waste into treasure." Therefore, it is widely used in agriculture, environmental protection, and other industries.

[0003] In existing technologies, high-temperature aerobic fermentation equipment is mostly based on horizontal fermenters. Horizontal fermenters typically use motor-driven internal stirring blades to agitate the materials inside, and are equipped with heating devices to maintain the internal temperature. Air is introduced through pipes to ensure an aerobic environment. In addition, some equipment includes simple crushing components at the material inlet, such as a single-roller crusher, to pre-process large pieces of raw material. After crushing, the material directly enters the fermentation zone, where fermentation is completed through natural accumulation or simple stirring. The overall structure is relatively simple, but the coordination between functional modules is weak.

[0004] However, existing high-temperature aerobic fermentation equipment suffers from numerous problems in practical applications, failing to meet the demands for efficient and stable fermentation. In the case of organic waste treatment in livestock farms, existing equipment does not adequately crush and dehydrate the raw materials. Lumpy manure or straw enters the fermentation tank without sufficient crushing, resulting in a small contact area between the material and oxygen, leading to incomplete fermentation. Furthermore, the excessively high moisture content in the raw materials cannot be effectively removed, prolonging the fermentation cycle and reducing processing efficiency. In the case of food waste fermentation, the material turning structure of existing equipment is poorly designed, causing materials to easily clump and accumulate inside the tank. Even with a stirring device, it is difficult to achieve uniform turning of the material, and some areas develop anaerobic environments due to lack of oxygen, affecting the fermentation effect. Therefore, this invention provides a high-efficiency vertical high-temperature aerobic fermentation device to address the shortcomings of existing technologies. Summary of the Invention

[0018] This invention provides a high-efficiency vertical high-temperature aerobic fermentation device. It has the following beneficial effects:

[0019] 1. This invention fully crushes and dehydrates the raw materials. The crushing process breaks down lumpy and fibrous raw materials into small and uniform materials, increasing the contact area with oxygen during subsequent fermentation and preventing insufficient fermentation inside large pieces of raw materials. The dehydration process reduces the moisture content of the materials, creating suitable humidity conditions for subsequent high-temperature aerobic fermentation, reducing fermentation obstacles, and improving overall processing efficiency.

[0020] 2. This invention enables the material to be circulated and evenly distributed during the fermentation process. The material can fall evenly into the fermentation area through the guiding structure, and then the bottom material is transported upward and scattered by the conveying component. The segmentation structure prevents caking and accumulation, and allows the material to fully contact with oxygen, ensuring a uniform fermentation reaction. If a heating module is added, a suitable fermentation temperature can be maintained, further accelerating the fermentation efficiency and ensuring stable fermentation results.

[0021] 3. This invention achieves intermittent and precise addition and anti-clogging through the addition of auxiliary materials. By driving the relevant structure through the driving component, the auxiliary materials can fall into the fermentation area intermittently as needed, ensuring accurate dosage and timely addition of auxiliary materials, and continuously supporting fermentation. At the same time, a knocking structure is set in the auxiliary material falling channel to prevent auxiliary material residue from clogging through vibration, ensuring smooth addition of auxiliary materials and helping the fermentation process to proceed efficiently and stably.

Detailed Implementation

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see the appendix Figure 1 -Appendix Figure 9 This invention provides a high-efficiency vertical high-temperature aerobic fermentation device. The assembly frame 1 serves as the basic support frame of the device and is formed by welding high-strength metal profiles. Its support part is fixed to the ground or fixed base by bolts, providing stable support for all functional mechanisms.

[0034] The motor 201 in the crushing mechanism 2 is detachably fixed to the top horizontal support of the assembly frame 1 by bolts. The output shaft of the motor 201 extends horizontally into the crushing box 202. The crushing box 202 is a metal box with an open top. Its bottom is fixedly connected to the top edge of the receiving box 301 of the pressing mechanism 3 by full welding. The internal cavity of the crushing box 202 is completely connected to the internal cavity of the receiving box 301, ensuring that the crushed material can fall into the receiving box 301 without any residue.

[0035] The receiving box 301 of the pressing mechanism 3 is a rectangular metal box. Its outer side wall is fixedly connected to the top support of the assembly frame 1 by angle steel brackets and bolts. The bottom of the receiving box 301 is kept horizontal, and several water permeable holes are pre-set at the bottom (for draining the water generated by the pressing). A water receiving tray can be set below the water permeable holes (the water receiving tray is suspended on the support of the assembly frame 1 by hooks).

[0036] The fermentation tank 601 of the fermentation mechanism 6 is a double-layer insulated metal tank (the inner layer is stainless steel, the outer layer is insulated rock wool, and the middle is filled with high-temperature resistant heat insulation material). The lower part of its outer wall is fixedly connected to the middle support of the assembly frame 1 by a ring clamp and bolts. The axis of the fermentation tank 601 remains vertical.

[0037] The motor 701 of the auxiliary material adding mechanism 7 is fixed to the middle support of the assembly frame 1 by a motor base and bolts. The output shaft of the motor 701 is horizontally oriented towards the fermentation tank 601. The auxiliary material storage box 707 is a sealed metal box with a feeding port on the top. Its outer wall is fixed to the middle support of the assembly frame 1 by an L-shaped bracket and bolts. The bottom discharge pipe 708 of the auxiliary material storage box 707 is fixed to the pre-set feeding hole on the upper side wall of the fermentation tank 601 by welding, ensuring that the inside of the discharge pipe 708 is completely connected to the inside of the fermentation tank 601.

[0038] The pressing mechanism 3 is the core component for material dewatering. The guide plate 302 is an inclined metal plate, and its two sides are fixedly connected to the inner side wall of the receiving box 301 by full welding process. The top of the guide plate 302 extends directly below the discharge port of the crushing box 202, and the bottom extends directly above the initial position of the push plate 304, ensuring that the crushed material can fall accurately in the area between the push plate 304 and the baffle 308.

[0039] The electric telescopic rod 303 is an industrial-grade electric push rod (the stroke is not less than the length of the receiving box 301). Its cylinder tail is fixedly connected to the outer wall of the receiving box 301 away from the discharge window 307 by a hinge. The output end is fixedly connected to the center position of the push plate 304 by bolts. The push plate 304 is a rectangular metal plate with a width consistent with the internal width of the receiving box 301.

[0040] The baffle 308 is a rectangular metal plate, its height is slightly less than the internal height of the receiving box 301, and its width is the same as the internal width of the receiving box 301. The outer side of the baffle 308 is slidably connected to the inner side wall of the receiving box 301. One side of the baffle 308 is fixedly connected to one end of the connecting block 306 by bolts. The connecting block 306 is a rectangular metal block, and its size matches the size of the discharge window 307. The tail of the cylinder of the electric telescopic rod 305 is fixedly connected to the outer side wall of the receiving box 301 by bolts. The output end is set upward and fixedly connected to the other end of the connecting block 306 by bolts.

[0041] The convex ball 309 is a hemispherical rubber protrusion, which is fixed to the side of the push plate 304 facing the baffle 308 and the side of the baffle 308 facing the push plate 304 respectively by glue or vulcanization process. It is used to increase the contact area of ​​the material during extrusion and improve the dewatering efficiency. The fixing plate 310 is a rectangular metal plate. One side of it is fixedly connected to the inner wall of the receiving box 301 by bolts (located on the side of the baffle 308 away from the push plate 304), and the other side is fixedly connected to two rubber plates 311 by glue. The rubber plates 311 are made of elastic rubber and their height is the same as that of the baffle 308. They are used to scrape off the material when the baffle 308 moves upward.

[0042] Fermentation mechanism 6 is the core component for achieving high-temperature aerobic fermentation. The receiving hopper 4 is a conical metal hopper, the top of which is fixedly connected to the bottom of the receiving box 301 by bolts (directly below the discharge window 307), and the bottom is fixedly connected to the inlet end of the solenoid valve 5 by a flange. The solenoid valve 5 is a normally closed electric flange valve, the outlet end of which is fixedly connected to the pre-set feed port on the top of the fermentation tank 601 by a flange. The control line of the solenoid valve 5 is connected to the main control system of the equipment to achieve precise material feeding.

[0043] The central barrel 605 is a cylindrical metal barrel, and its outer wall is fixedly connected to one end of a plurality of stabilizing rods 606 by welding. The stabilizing rods 606 are metal rods, and the other end is fixedly connected to the inner wall of the fermentation barrel 601 by welding, so as to ensure that the central barrel 605 remains coaxial and stable inside the fermentation barrel 601.

[0044] Motor 603 is a high-temperature resistant geared motor. Its body is fixedly connected to the bottom center of fermentation tank 601 by bolts. Its output shaft passes through the bottom of fermentation tank 601 and is fixedly connected to the bottom end of auger conveyor roller 604 by coupling. Auger conveyor roller 604 is a spiral blade type conveying structure. Its outer side is clearance-fitted with the inner side wall of central tank 605 and is used to convey the material at the bottom of central tank 605 upward.

[0045] The conical cover 608 is a metal conical structure (pointed at the top and wide at the bottom). Its bottom is welded to the top of multiple support plates 607. The support plates 607 are metal plates, and their bottoms are fixedly connected to the top of the central barrel 605 by welding. The function of the conical cover 608 is to guide the material fed into the receiving hopper 4 to the annular area between the central barrel 605 and the fermentation barrel 601, so as to prevent the material from falling directly into the interior of the central barrel 605.

[0046] The inclined ring 609 is an annular metal plate (with a 45° inclined cross-section). Its inner side is fixedly connected to the top of the central barrel 605 by welding, and its outer side faces the inner wall of the fermentation barrel 601. It is used to guide the material conveyed upward by the auger conveyor roller 604 to the annular area. The dividing block 610 is uniformly fixed to the inner wall of the fermentation barrel 601 by welding (located in the annular area). It is used to divide the falling material into small strands to prevent the material from accumulating and clumping.

[0047] The connecting frame 611 is an annular metal frame. Its outer side is fixedly connected to the bottom of the inner wall of the fermentation tank 601 by welding, and its inner side is fixedly connected to the bottom of the central tank 605 by welding. Several return ports 612 are evenly opened on the side wall of the connecting frame 611 to return the material at the bottom of the annular area to the interior of the central tank 605, so as to realize the circulation and turning of the material.

[0048] The discharge port 602 is a circular metal pipe, which is fixedly connected to the bottom side wall of the fermentation tank 601 by welding. A manual butterfly valve is installed on the discharge port 602 for discharging materials after fermentation. A heating module (such as an electric heating wire or a heat transfer oil heating pipe) is installed between the double side walls of the fermentation tank 601. The control line of the heating module is connected to the main control system, which can stabilize the internal temperature of the fermentation tank 601 at 50-70℃ (the suitable temperature for high-temperature aerobic fermentation).

[0049] The auxiliary material adding mechanism 7 is used for intermittently adding fermentation auxiliary materials (such as inoculum, conditioner, etc.). The auxiliary material storage box 707 is equipped with an inclined guide plate inside (to ensure that the auxiliary materials can flow naturally to the bottom). Its bottom center is fixedly connected to the top of the feeding pipe 708 by welding. The feeding pipe 708 is a cylindrical metal pipe, and its bottom end is fixedly connected to the upper side wall of the fermentation tank 601 by welding. The internal diameter of the feeding pipe 708 matches the particle size of the auxiliary materials (to prevent blockage).

[0050] The baffle plate 703 is a rectangular metal plate (its dimensions match the internal cross-section of the feed tube 708), and its outer side is slidably connected to the inner wall of the feed tube 708 (it can move up and down to open and close the feed tube 708); the outer sides of the baffle plate 703 are fixedly connected to two fixing blocks 704 by bolts, and the fixing blocks 704 are rectangular metal blocks; the bottom of one of the fixing blocks 704 is fixedly connected to the top of the tension spring telescopic rod 705 by bolts, and the bottom end of the tension spring telescopic rod 705 is connected to the top of the tension spring telescopic rod 705 by bolts. The bolt is fixedly connected to the top of the feed tube 708. The tension spring telescopic rod 705 consists of an outer tube, an inner rod, and a tension spring (the tension spring is sleeved on the outside of the inner rod, and in its natural state, it pulls the baffle plate 703 downward to close the feed tube 708). The bottom of another fixing block 704 is fixedly connected to the top of the striking post 706 by bolts. The striking post 706 is a metal rod, and a rubber block is fixed to its bottom with glue. It is used to strike the feed tube 708 when the baffle plate 703 moves to prevent the auxiliary material from blocking the tube.

[0051] The output shaft of motor 701 is fixedly connected to cam 702 via a key connection. The contact rod 709 is a metal rod, one end of which is welded to one side of the baffle plate 703, and the other end extends horizontally to the outer periphery of cam 702. The outer side of the contact rod 709 is always in contact with the outer periphery of cam 702 (under the tension of the tension spring telescopic rod 705). When motor 701 drives cam 702 to rotate, the protruding part of cam 702 will push the contact rod 709 to move upward, thereby driving the baffle plate 703 to open the feed pipe 708 (auxiliary material falls). When the protruding part rotates away, the tension spring telescopic rod 705 pulls the baffle plate 703 to reset and close, realizing the intermittent addition of auxiliary material.

[0052] First, start motor 201 (crush raw materials) and monitor the feed rate of crushing box 202. When the material accumulates to the preset amount, turn off motor 201 and start electric telescopic rod 303 (compress material). After the preset compression time, start electric telescopic rod 305 (open baffle 308) and then start electric telescopic rod 303 (push material to receiving hopper 4).

[0053] After the material is pushed to the receiving hopper 4, the solenoid valve 5 is activated (the material falls into the fermentation tank 601), the solenoid valve 5 is closed, and the second motor 603 (circulates and turns the material) and the heating module (heats to the set temperature) are activated at the same time. During the fermentation process, the control system activates the third motor 701 at preset intervals (intermittently adds auxiliary materials) until the fermentation is completed.

[0054] After fermentation is complete, turn off motor 2 (603), heating module and motor 3 (701), open the butterfly valve of discharge port 602, and start motor 2 (603) at the same time (to push the material to discharge port 602). After the material is discharged, turn off all equipment.

[0055] Specifically, firstly, the operator feeds the raw material to be processed into the crushing box 202 from the top. During this process, motor 201 is started simultaneously. The output of motor 201 drives one of the crushing rollers 203, which is fixedly connected to it, to rotate. Since one end of each of the two crushing rollers 203 is fixed with a meshing cylindrical gear 204, under the action of gear meshing transmission, the other crushing roller 203 will rotate in the opposite direction. The coordinated rotation of the two crushing rollers 203 can fully shear and crush the input raw material. This step can... Breaking down lumpy and fibrous raw materials into finer and more uniform particles not only increases the contact area between the material and oxygen during subsequent fermentation, but also avoids the problem of insufficient internal fermentation when large pieces of raw materials are fermented. The crushed material will fall naturally into the receiving box 301 below under the action of gravity. The guide plate 302 fixed inside the receiving box 301 will guide the falling material, so that the material is accurately gathered in the area between the baffle 308 and the push plate 304, preventing the material from scattering in other corners of the receiving box 301 and causing accumulation or waste.

[0056] Then, the electric telescopic rod 303 is activated. The output end of the electric telescopic rod 303 pushes the push plate 304 to move along the inner bottom wall of the receiving box 301 toward the baffle 308, pushing the gathered crushed material toward the baffle 308 and applying extrusion pressure. The pre-set holes at the bottom of the receiving box 301 can discharge the water released from the material during the extrusion process in time, reducing the moisture content in the material and creating suitable humidity conditions for subsequent high-temperature aerobic fermentation. At the same time, the multiple convex balls 309 fixed on the side of the push plate 304 and the baffle 308 can apply multi-point pressure to the material during extrusion, further improving the dehydration effect and the looseness of the material.

[0057] After extrusion, start the second electric telescopic rod 305. The output end of the second electric telescopic rod 305 drives the connecting block 306 to move upward. The baffle 308, which is fixedly connected to the connecting block 306, will move upward along the inner wall of the receiving box 301, thereby fully opening the discharge window 307 on one side of the receiving box 301. At this time, control the first electric telescopic rod 303 again to push the push plate 304. The push plate 304 will push the extruded material smoothly to the discharge window 307 and fall into the receiving hopper 4 below. The receiving hopper 4 can temporarily receive and buffer the material to prevent the material from splashing out due to impact when it falls directly. Then start the solenoid valve 5. After the solenoid valve 5 is opened, the internal channel of the receiving hopper 4 is opened, and the material will fall smoothly into the interior of the fermentation tank 601 along the channel. Then close the solenoid valve 5 to prevent the gas or heat generated by fermentation inside the fermentation tank 601 from being lost to the outside through the receiving hopper 4.

[0058] The material falling into the fermentation tank 601 first comes into contact with the conical cover 608 at the top of the central tank 605, which is supported and fixed by the support plate 607. The inclined structure of the conical cover 608 guides the material to slide outwards, so that the material is evenly distributed in the annular area between the central tank 605 and the fermentation tank 601, preventing the material from accumulating directly in one position of the fermentation tank 601. Then, the material gradually moves downwards under the action of gravity, and finally enters the bottom of the central tank 605 through the return port 612 opened on the connecting frame 611. At this time, the second motor 603 is started. The output end of the second motor 603 drives the auger conveyor roller 604 to rotate inside the central tank 605. The spiral structure of the auger conveyor roller 604 will push the bottom of the central tank 605... The material is continuously conveyed upwards. When the material is conveyed to the top of the central barrel 605, it will come into contact with the inclined ring 609 fixed at the top of the central barrel 605. Under the guidance of the inclined ring 609, it will fall to the surroundings again. During the fall, it will be divided into small strands by multiple dividing blocks 610 fixed inside the fermentation barrel 601. This cyclical turning process can not only prevent the material from clumping or piling up inside the fermentation barrel 601, but also make the material fully contact with the oxygen inside the fermentation barrel 601, ensuring that the fermentation reaction proceeds evenly. At the same time, if a heating module is equipped outside the fermentation barrel 601, the internal temperature of the fermentation barrel 601 can be maintained within a suitable range for high-temperature aerobic fermentation, further accelerating the fermentation efficiency and improving the fermentation effect.

[0059] In addition, the auxiliary material storage box 707 is pre-stored with auxiliary materials that promote fermentation (such as inoculum, conditioner, etc.). During fermentation, motor 701 can be started. The output end of motor 701 drives cam 702 to rotate. When the protruding part of cam 702 rotates to contact the touch rod 709, it will push the touch rod 709 upward. The baffle plate 703, which is fixedly connected to the touch rod 709, will slide upward along the inside of the feed pipe 708. At this time, the channel of the feed pipe 708 is opened, and the auxiliary materials in the auxiliary material storage box 707 will fall into the fermentation tank 601 along the feed pipe 708. When the protruding part of cam 702 rotates away from the touch rod 709, The tension spring telescopic rod 705, connected to the fixing block 704 on one side of the baffle plate 703, will pull the baffle plate 703 back to its original position under its own tension, thus closing the feed pipe 708 again. At the same time, the striking column 706 connected to the fixing block 704 on the other side of the baffle plate 703 will move downward as the baffle plate 703 is reset, and the rubber block at its bottom will strike the outer wall of the feed pipe 708. Vibration will prevent the auxiliary material from remaining or clogging in the feed pipe 708. By intermittently adding auxiliary material, the amount of auxiliary material can be accurately and timely added during the fermentation process, providing continuous support for the fermentation of the material, and ultimately ensuring that the entire high-temperature aerobic fermentation process is carried out efficiently and stably.

[0060] Working principle: First, the raw material is fed into the crushing box 202 from the top. At the same time, the motor 201 is started to drive one of the crushing rollers 203 to rotate. Under the meshing action of the two cylindrical gears 204, the other crushing roller 203 rotates at the same time, thereby crushing the raw material. The crushed material falls into the receiving box 301. Under the guidance of the guide plate 302, the material falls between the baffle 308 and the push plate 304. Then, the electric telescopic rod 303 is started to push the push plate 304 to move, pushing the crushed material onto the baffle 308 for compression. The bottom of the receiving box 301 can be opened with holes to facilitate the discharge of squeezed water. With the cooperation of multiple convex balls 309, a better compression effect is achieved.

[0061] Then, the electric telescopic rod 305 is activated, causing the connecting block 306 to move upward. This causes the baffle 308 to move upward, opening the discharge window 307. The push plate 304 then pushes the material out of the discharge window 307, where it falls into the receiving hopper 4. The solenoid valve 5 is then activated to open the internal channel of the receiving hopper 4, allowing the material to fall into the fermentation tank 601. The solenoid valve 5 is then closed. The material falling into the fermentation tank 601 will first fall to the top of the conical cover 608 and slide down into the central tank 605 to ferment. The material enters the bottom of the central barrel 605 from the return port 612 on the connecting frame 611 at the middle position of the barrel 601. The starting motor 603 drives the auger conveyor roller 604 to rotate, which can convey the material upward and then fall down along the inclined surface of the inclined ring 609 and be divided by the dividing block 610 to prevent the material from accumulating in the fermentation barrel 601. The material can be continuously turned over during the fermentation process. At the same time, a heating module can be equipped on the outside of the fermentation barrel 601 to increase the internal temperature of the fermentation barrel 601.

[0062] In addition, the auxiliary material storage box 707 stores auxiliary materials for fermentation. When the motor 701 is started, it drives the cam 702 to rotate, which in turn hits the touch rod 709. Then the baffle plate 703 is moved upward, and then the baffle plate 703 is reset by the pulling force of the tension spring telescopic rod 705. At the same time, the striking column 706 will strike the feed pipe 708. In this way, auxiliary materials can be intermittently added to assist fermentation inside the fermentation tank 601.
