Description

Technical Field

[0001] This application relates to the field of organic waste biological treatment equipment technology, and in particular to an aerobic treatment machine for organic waste, specifically a horizontal aerobic treatment machine for organic waste that achieves directional and quantitative oxygen supply. Background Technology

[0002] Organic waste is rich in organic matter, and its resource utilization can be achieved by utilizing microorganisms to decompose and transform organic matter under aerobic conditions. The core factors affecting the efficiency of aerobic fermentation include microorganisms and environmental conditions, with fermentation temperature and oxygen content being the most important influencing factors. In the process of treating organic waste using high-temperature aerobic fermentation technology, the waste treatment machine operates automatically according to the set process parameters and programs under the PLC logic control of its electrical control system. The entire production process involves stages such as feeding, heating, fermentation, drying, cooling, and discharging, ultimately producing the fermented product. During high-temperature aerobic fermentation, air needs to be introduced into the waste treatment machine. The purpose of introducing air is twofold: firstly, to provide the material with the temperature and oxygen conditions required for aerobic fermentation and drying; and secondly, to act as a carrier for the water vapor (vaporization of moisture within the material) that escapes during fermentation and drying, which is then discharged through the dust removal and exhaust system.

[0003] Traditional aerobic fermentation machines for waste typically include an "oxygenation supplementation system" to introduce air into the material. This system is generally implemented in one of two ways:

[0004] 1. Direct air intake by a supplementary air blower: In horizontal aerobic fermentation machines for organic waste, the high density of the material and the low air pressure of the supplementary air blower result in poor air penetration. This prevents the organic waste material from receiving sufficient oxygen, leading to low oxygen content and hindering the rapid growth of microorganisms and enzymes, resulting in low processing efficiency. Furthermore, the large air volume and high flow rate of the supplementary air blower can cause short-circuiting between the air intake and exhaust in the chamber, leading to a significant loss of heat from the horizontal aerobic fermentation machine for organic waste and resulting in high energy consumption.

[0005] 2. Air is introduced through the air inlet on the central mixing shaft jacket: In horizontal aerobic fermentation treatment machines for organic waste, air is introduced through the air inlet on the central mixing shaft jacket. For example... Figure 1An air supply hole 01 is provided on the jacket of the central stirring shaft. The arrow in the diagram indicates the air supply path. When processing organic waste, the horizontal aerobic fermentation machine typically loads 70-75% of its total volume. This means that the material thickness varies depending on its distance from the central stirring shaft. In traditional horizontal aerobic fermentation machines, the material thickness from the central shaft to the bottom of the equipment is much greater than the material thickness from the central shaft to the top. When air is introduced into the material through the jacket hole of the central shaft, the uneven thickness of the material in different directions causes different resistance. According to the principle of minimum resistance in the air supply path, most of the gas escapes from the top of the material and cannot penetrate to the bottom layer, resulting in insufficient oxygen supply. This leads to uneven oxygen content in the material, hindering the rapid growth of microorganisms and enzymes, and resulting in low processing efficiency.

[0006] It is evident that traditional aerobic fermentation machines for waste treatment, whether oxygenation is achieved by direct blowing of air into the material using a supplementary air fan or by air injection holes in the central mixing shaft jacket, suffer from poor aeration penetration and insufficient oxygenation, thus hindering efficient fermentation. Therefore, it is necessary to propose a new technical solution to address the problems existing in the current technology. Summary of the Invention

[0007] This application provides a horizontal aerobic organic waste treatment machine that enables directional and quantitative oxygen supply, thereby solving the problems of poor oxygen aeration penetration and high oxygen loss rate in traditional aerobic fermentation machines for waste.

[0008] To achieve the above objectives, this application provides the following technical solution:

[0009] This application provides a horizontal aerobic organic waste treatment machine for directional and quantitative oxygen supply, including a stirring device disposed within a casing. The stirring device includes a stirring shaft and stirring plates mounted on the stirring shaft via a hollow support rod. An air passage is formed on the stirring shaft communicating with the inner cavity of the hollow support rod. Multiple air supply holes are opened on the side wall of the hollow support rod facing away from the stirring direction. A rotary air inlet valve is installed at one end of the stirring shaft. The rotary air inlet valve includes a valve housing and a fixed valve body and a rotating valve body disposed within the valve housing. The rotary valve body is integrally connected to the stirring shaft. One or more air delivery channels are opened on the rotary valve body, and the air delivery channels are connected to the air passage. The fixed valve body is opened with a rotary adjustment air intake channel, and the rotary adjustment air intake channel is connected to the air intake end of the rotary air intake valve. The fixed valve body is detachably connected to the valve shell through an air intake angle adjustment disc. By adjusting the rotation angle of the rotary adjustment air intake channel, the air supply hole on the hollow support rod is connected to the gas in the rotary adjustment air intake channel when the hollow support rod rotates to the target rotation range.

[0010] Furthermore, in the above technical solution, a detection module is provided inside the casing. The detection module includes a mixing chamber pressure detector, an oxygen content detector, a temperature sensor, and a moisture detector. The detection module is connected to the control system signal. The control system detects the operating parameters of the organic waste material inside the casing during the aerobic treatment process through the detection module, and then uses frequency conversion to regulate the output of the air supply equipment. The air supply equipment includes a blower and an air storage tank. The blower is used to transport the gas in the air storage tank to the air inlet end of the rotary air inlet valve.

[0011] Furthermore, one end of the valve housing is fastened to the passive end of the stirring shaft by a fixing bolt, and the other end of the valve housing is provided with a mounting hole for installing the air inlet angle adjustment plate. The air inlet angle adjustment plate is detachably connected to the mounting hole by a connecting bolt. An air inlet pipe for installing the valve is inserted through the air inlet angle adjustment plate and is connected to the fixed valve body. After removing the connecting bolt, rotating the fixed valve body can cause the rotary adjustment air inlet channel to rotate around the central axis of the mounting hole, so that when the hollow support rod rotates into the material pile, its air supply hole is connected to the gas inlet channel.

[0012] Furthermore, the fixed valve body is a disc structure, and the rotary regulating air intake channel is an arc-shaped channel opened on the disc surface near the edge of the disc structure. The fixed valve body has one or more of the rotary regulating air intake channels. The rotary valve body is a disc structure, and multiple air delivery channels are radially opened on the rotary valve body with its center as the center. When the rotary valve body rotates with the stirring shaft, it can drive the air delivery channels on it to rotate relative to the rotary regulating air intake channels, so as to realize the connection or cut-off of the air delivery channels and the rotary regulating air intake channels.

[0013] Furthermore, the arc-shaped channel is a half-circle arc formed on the surface of the fixed valve body; the rotary valve body is provided with three air delivery channels, which are evenly distributed on the half-circle surface of the rotary valve body.

[0014] Furthermore, the active end of the stirring shaft is mounted on the housing via an active support bearing, the active end of the stirring shaft is connected to a stirring drive motor, the passive end of the stirring shaft is mounted on the housing via a passive support bearing, and the passive end of the stirring shaft extends outward to form an extension section, on which the rotary valve body is machined.

[0015] Furthermore, the stirring blade structure is a spiral ribbon or a paddle; the spiral ribbon is a spiral ribbon structure wound around the periphery of the stirring shaft, and the spiral ribbon is connected and fixed to the stirring shaft by a hollow support rod arranged in the radial direction of the stirring shaft; the paddle is a blade structure, and the paddle is connected and fixed to the stirring shaft by a hollow support rod arranged in the radial direction of the stirring shaft.

[0016] Furthermore, the stirring shaft is fitted with a stainless steel pipe, and the gap between the stirring shaft and the stainless steel pipe forms the air passage. The air delivery channel on the rotary valve body is connected to the gas inside the hollow support rod through the air passage. Two adjacent hollow support rods located on the same side of the stirring shaft are connected to each other through an extension pipe.

[0017] Compared with the prior art, this application has at least the following beneficial effects:

[0018] 1. This application improves oxygen transfer efficiency by forming air channels on the stirring shaft and connecting them to the inner cavity of the hollow support rod. This allows air fed into the air channels to be directly delivered to the stirring area. Multiple air supply holes on the side wall of the hollow support rod facing away from the stirring direction allow for direct oxygen supply to the material during stirring, enhancing oxygen permeability and ensuring more even distribution of oxygen in the fermentation material. Furthermore, the air supply holes are located away from the material's movement direction, thus avoiding pressure contact with the material and preventing blockage during operation. Additionally, the structural design of the fixed and rotating valve bodies of the rotary air inlet valve allows for dynamic control of the gas flow as the stirring shaft rotates. By adjusting the rotation angle of the rotary air intake channel, the timing and location of gas supply can be precisely controlled. When the hollow support rod rotates to the target rotation range, its air supply hole connects with the gas in the rotary air intake channel, achieving directional and quantitative oxygen supply. This reduces oxygen loss and improves oxygen utilization efficiency. Therefore, the horizontal organic waste aerobic treatment machine provided in this application achieves precise control over the location, timing, and amount of gas supply through the structural design of the rotary air intake valve, stirring shaft, and hollow support rod, realizing directional and quantitative oxygen supply to the horizontal organic waste aerobic treatment machine, thereby improving oxygen penetration and utilization rate and reducing oxygen loss.

[0019] 2. This application enables real-time acquisition of operating parameters of organic waste materials during aerobic treatment via a detection module. Connecting the detection module to the control system allows the control system to adjust the output of the gas supply equipment according to the operating parameters, achieving quantitative gas delivery. Furthermore, the structural design of the rotary air inlet valve, stirring shaft, and hollow support rod allows for the control of the air supply holes on the hollow support rod to supply gas within a specific rotation range when the rotation angle of the rotary air inlet valve is adjusted. This addresses the different accumulation patterns formed by materials of varying densities during stirring, ensuring that the horizontal aerobic organic waste treatment machine maintains suitable oxygen supply conditions for the growth of microbial agents and enzymes during the biological treatment of organic waste.

[0020] 3. The detachable connection design between the air inlet angle adjustment disc and the valve body in this application facilitates the rotation and adjustment of the air inlet angle adjustment disc, while also facilitating maintenance and replacement, reducing maintenance time and costs. Furthermore, rotating the air inlet angle adjustment disc allows adjustment of the position of the rotating air inlet channel on the fixed valve body. Combined with rotating the valve body, this enables more precise air supply angle adjustment, ensuring gas flow between the air supply port and the rotating air inlet channel within the target air supply area. This addresses different material densities and their resulting accumulation patterns during mixing. The air supply port can be dynamically adjusted according to the material pile position, enhancing the system's adaptability. Additionally, the air supply angle can be flexibly adjusted based on the characteristics of different materials and fermentation requirements, reducing oxygen loss and improving oxygen utilization.

[0021] 4. This application achieves more precise gas distribution through a half-circular arc channel on the fixed valve body and three evenly distributed air delivery channels on the rotary valve body. The air delivery channels on the rotary valve body are radially arranged around the center of the rotary valve body, which helps improve gas flow efficiency and reduce gas resistance during transport. The disc structure of the fixed and rotary valve bodies simplifies the mechanical design, making the entire system more compact and easier to install and maintain. Furthermore, the connection or disconnection of the air delivery channels and the rotary regulating air inlet channel can be dynamically adjusted according to the rotation of the stirring shaft, which helps optimize gas flow. The contact between the valve body and the organic waste material improves the efficiency of aerobic fermentation and reduces oxygen loss. When the rotary valve body rotates with the stirring shaft, it can quickly respond to changes in the material pile and adjust the gas supply in time, improving the system's response speed. This dynamic adjustment of the gas supply can adapt to different fermentation conditions and material characteristics. By adjusting the relative position of the air delivery channel and the rotary regulating air inlet channel, precise gas supply can be achieved for different material pile shapes and different fermentation stages. By precisely controlling the gas supply, the instability of the fermentation process caused by uneven or excessive gas supply can be reduced, thereby improving the stability and reliability of the entire system.

[0035] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "comprising," "including," "having," etc., used in this application also mean "not limited to" (certain units, components, materials, steps, etc.).

[0037] The terms "upper," "lower," "left," and "right" used in this application are generally for the purpose of intuitive understanding in conjunction with the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0038] This application provides a horizontal aerobic organic waste treatment machine that achieves directional and quantitative oxygen supply. Compared with existing horizontal aerobic organic waste fermentation machines that directly blow in oxygen via a make-up air fan, which suffers from poor penetration, low oxygen content in the material, and high energy consumption, this application also addresses the shortcomings of existing horizontal aerobic organic waste fermentation machines that use air injection holes on the central mixing shaft jacket. These latter machines suffer from uneven material thickness in different directions, causing most of the gas to escape from the top of the material and fail to penetrate to the bottom layer, resulting in insufficient oxygen supply and lower oxygen content in the material. To address the problems of uneven oxygen content, slow growth of microorganisms and enzymes, and low processing efficiency, this application utilizes a rotary air inlet valve with a variable air supply angle and air inlets on a hollow support rod on the stirring shaft, facing away from the stirring direction. This allows for the control of fresh air intake through the corresponding opening and closing of the arc-grooved air inlet channel on the fixed valve body and the air delivery channel on the rotary valve body. This ensures that the air supply holes on the hollow support rod supply air when in contact with the material and stop supplying air after the material leaves, preventing oxygen loss due to the lack of material resistance at the upper part of the air supply holes on the hollow support rod. The structural principle of this horizontal aerobic organic waste treatment machine, capable of achieving directional and quantitative oxygen supply, will be described in detail below with reference to the accompanying drawings.

[0039] See Figure 2The horizontal aerobic organic waste treatment machine for directional and quantitative oxygen supply provided in this application mainly includes: a stirring device installed inside the machine casing, the stirring device including a stirring shaft 1 and a stirring plate structure mounted on the stirring shaft 1 via a hollow support rod 2, an air passage 6 formed on the stirring shaft 1 communicating with the inner cavity of the hollow support rod 2, multiple air supply holes 3 opened on the side wall of the hollow support rod 2 facing away from the stirring direction, and a rotary air inlet valve 8 installed at one end of the stirring shaft 1, the rotary air inlet valve 8 including a valve shell 9 and a fixed valve body 11 and a rotating valve body 13 disposed inside the valve shell 9, the rotary air inlet valve 8... The rotary valve body 13 is integrally connected to the stirring shaft 1. One or more air delivery channels 14 are opened on the rotary valve body 13, and the air delivery channels 14 are connected to the air passage 6. The fixed valve body 11 is provided with a rotary adjustment air inlet channel 12, which is connected to the air inlet end of the rotary air inlet valve 8. The fixed valve body 11 is detachably connected to the valve shell 9 through the air inlet angle adjustment plate 15. By adjusting the rotation angle of the rotary adjustment air inlet channel 12, the air supply hole 3 on the hollow support rod 2 is connected to the gas in the rotary adjustment air inlet channel 12 when the hollow support rod 2 rotates to the target rotation range.

[0040] The above scheme allows for adjustment of the rotary air intake valve 8 based on the different packing morphologies (material packing angle) formed during the mixing process according to varying material densities. During adjustment, the air intake angle adjustment disc 15 is disassembled, and the fixed valve body 11 is adjusted so that the rotary adjustment air intake channel 12 is at the target rotation position. Then, the fixed air intake angle adjustment disc 15 is installed and secured. During mixing, air is supplied intermittently at the target angle, ensuring that the air supply port 3 operates when in contact with the material and stops supplying air when it leaves the material. This ensures sufficient oxygen supply to the material, maintaining suitable conditions for the growth of microbial agents and enzymes in the horizontal organic waste aerobic treatment machine during the organic waste biological treatment process. This results in the production of high-quality fermented products while reducing energy consumption and oxygen loss. Furthermore, see [link to other documentation]. Figure 6 Multiple air supply holes 3 are opened on the side wall of the hollow support rod 2 facing away from the stirring direction, which can directly supply oxygen to the material during the stirring process, enhance the oxygen permeability, and make the oxygen more evenly distributed in the fermentation material. Moreover, the air supply holes 3 are located in a direction that is not facing the material movement, so there is no pressure contact with the material, which can prevent the material from clogging during operation.

[0041] In a preferred embodiment of this application, a detection module is installed inside the casing. This module includes a mixing chamber pressure detector, an oxygen content detector, a temperature sensor, and a moisture detector. The detection module can be connected to a control system signal. The control system can detect the operating parameters of the organic waste material inside the casing during the aerobic treatment process through the detection module, and then adjust the output of the gas supply equipment via frequency conversion, thus achieving quantitative gas delivery. The control system can be an electrical control panel. The electrical control panel completes the entire biological treatment process according to a program pre-stored in a programmable logic controller (PLC). After fermentation begins, the PLC collects parameters in real time from various detection instruments in the system. The PLC can automatically adjust the gas supply of the gas supply fan or stop it based on the real-time data transmitted by the detection instruments.

[0042] In a preferred embodiment of this application, see [link to application]. Figure 2 The gas supply equipment in this application may include a blower 18 and an air storage tank 19. The blower 18 is used to deliver the gas in the air storage tank 19 to the air inlet end of the rotary air inlet valve 8. Depending on the application requirements, the air storage tank 19 can also be directly replaced with an oxygen tank.

[0043] In a preferred embodiment of this application, see [link to application]. Figure 3 , 4 One end of the valve housing 9 of the aforementioned rotary air intake valve 8 is fastened to the passive end of the stirring shaft 1 by a fixing bolt 10. The other end of the valve housing 9 is provided with a mounting hole for mounting the air intake angle adjustment disc 15. The air intake angle adjustment disc 15 is detachably connected to the mounting hole by a connecting bolt 16. A valve air intake pipe 17 is inserted through the air intake angle adjustment disc 15 and is connected to the fixed valve body 11. After removing the connecting bolt 16, rotating the fixed valve body 11 allows the rotary adjustment air intake channel 12 to rotate around the central axis of the mounting hole, so that when the hollow support rod 2 rotates into the material pile, the air supply hole 3 on it is connected to the rotary adjustment air intake channel 12 for gas conduction. This detachable connection design not only facilitates the rotation adjustment operation of the air intake angle adjustment disc 15, but also facilitates the maintenance and replacement of the air intake angle adjustment disc 15, reducing maintenance time and costs.

[0044] In a preferred embodiment of this application, the fixed valve body 11 is a disc structure, and the rotary adjustable air intake channel 12 is an arc-shaped channel formed on the disc surface near the edge of the disc structure. One or more rotary adjustable air intake channels 12 are formed on the fixed valve body 11. Figure 8 The fixed valve body 11 has two rotary adjustable air intake channels 12. Correspondingly, the rotary valve body 13 has a disc structure, and multiple air delivery channels 14 are radially arranged on the rotary valve body 13 with its center as the center. Figure 8When the rotary valve body 13 rotates with the stirring shaft 1, it can drive the air delivery channel 14 on it to rotate relative to the rotary adjustment air inlet channel 12, so as to realize the connection or cut-off of the air delivery channel 14 and the rotary adjustment air inlet channel 12.

[0045] This application achieves more precise air supply angle adjustment by adjusting the position of the rotary adjustable air inlet channel 12 on the fixed valve body 11 and cooperating with the air delivery channel 14 on the rotary valve body 13. This ensures that the air supply port 3 and the rotary adjustable air inlet channel 12 are connected in the target air supply area, which can cope with different material densities forming different accumulation patterns during the stirring process. The air supply port 3 can be dynamically adjusted according to the position of the material pile, which enhances the adaptability of the system. It can also flexibly adjust the air supply angle according to the characteristics of different materials and fermentation requirements, reduce oxygen loss, and improve oxygen utilization.

[0046] In one specific embodiment, see Figure 4 The aforementioned arc-shaped channel is a half-circle arc formed on the surface of the fixed valve body 11; the rotary valve body 13 is provided with three air delivery channels 14, which are evenly distributed on the half-circle surface of the rotary valve body 13. This application achieves more precise gas distribution through the half-circle arc channel on the fixed valve body 11 and the three evenly distributed air delivery channels 14 on the rotary valve body 13; the air delivery channels 14 on the rotary valve body 13 are radially arranged with the center of the rotary valve body 13 as the center, which helps to improve the efficiency of gas flow and reduce the resistance of gas during transportation. Of course, in specific manufacturing and application processes, the size and position of the arc-shaped channel on the fixed valve body 11 can be customized according to the material requirements in the mixing chamber and the shape of the material pile after mixing, and the number, position, and size of the air delivery channels 14 on the rotary valve body 13 can also be customized accordingly.

[0047] In the specific manufacturing and installation process, the active end of the aforementioned stirring shaft 1 is mounted on the housing via an active support bearing. The active end of the stirring shaft 1 is connected to the stirring drive motor. The passive end of the stirring shaft 1 is mounted on the housing via a passive support bearing. The passive end of the stirring shaft 1 extends outward to form an extension section, and a rotary valve body 13 is machined from the extension section. See [reference needed]. Figure 2 , 5 The aforementioned stirring plate structure can be either a spiral ribbon 4 or a paddle. The spiral ribbon 4 is a spiral ribbon structure wound around the periphery of the stirring shaft 1 in a spiral shape. The paddle is a plate structure. Both the spiral ribbon 4 and the paddle are connected and fixed to the stirring shaft 1 by a hollow support rod 2 arranged in the radial direction of the stirring shaft 1.

[0048] To deliver the gas from the rotary air inlet valve 8 into the hollow support rod 2, a stainless steel pipe 5 can be fitted over the stirring shaft 1 during manufacturing. The gap between the stirring shaft 1 and the stainless steel pipe 5 serves as the air passage 6. The air delivery channel 14 on the rotary valve body 13 communicates with the gas inside the hollow support rod 2 through the air passage 6. Adjacent hollow support rods 2 on the same side of the stirring shaft 1 are connected by an extension pipe 7. Alternatively, a stainless steel air delivery pipe can be installed in the air passage 6. At bends in the gas delivery path, stainless steel elbows and other pipe fittings can be used to connect the air delivery pipes.

[0049] The horizontal aerobic organic waste treatment machine provided in this application can improve the oxygen supply during the aerobic biological treatment of organic waste, achieving uniform oxygen supply with controllable oxygen levels. Furthermore, this application can adjust the air inlet angle based on the different stacking angles formed during the mixing process according to different material densities, preventing ineffective oxygen supply. The technical solution provided in this application can improve the efficiency of microbial bacteria or enzyme preparations in the biological treatment of organic waste, shorten the organic waste treatment time, and improve the quality of fermentation products.

[0050] The following is a detailed description of the specific working process of the horizontal aerobic organic waste treatment machine provided in this application.

[0051] Before operation, the horizontal aerobic organic waste treatment machine provided in this application first needs to test the nitrogen source content, moisture content, and bulk density of the organic waste. By calculating the data of the organic waste, moisture, and carbon source adjustment materials, the feeding ratio of the organic waste biological treatment equipment is determined, and two or more types of organic waste materials are mixed. In one application example, the moisture content of the mixed material is 55-60%, the carbon-to-nitrogen ratio is 25:1, and the bulk density is 700-900 kg / m³. 3 The material to be aerobic fermentation is obtained. Then, based on the characteristics of the material after mixing, the material accumulation angle after stirring is estimated and observed. The air inlet angle adjustment plate 15 is adjusted according to the material accumulation angle. The above work only needs to be adjusted once at the initial stage of operation or after changing the type of waste to be treated.

[0052] like Figure 7As shown: At this time, the opening and closing of the fresh air intake is controlled by the arc-shaped rotary adjustable air intake channel 12 on the fixed valve body 11. When the preset pipe opening inside the stirring shaft 1 (i.e., the air passage 6 inside the stirring shaft 1) moves to the lower left opening of the fixed valve body 11 (i.e., the arc-shaped rotary adjustable air intake channel 12), the air passage 6 is connected to the rotary adjustable air intake channel 12 through the air delivery channel 14 on the rotary valve body 13, and oxygen is supplied to the material. When the preset pipe opening inside the stirring shaft 1 rotates to the upper right of the fixed valve body 11, the air delivery channel 14 on the rotary valve body 13 does not correspond to the rotary adjustable air intake channel 12, the gas delivery is cut off, and oxygen supply to the material stops. Therefore, this application can ensure that the air supply hole 3 on the hollow support rod 2 supplies air when in contact with the material and stops supplying air after leaving the material, preventing oxygen loss due to the lack of material resistance when the air supply hole 3 on the hollow support rod 2 is in a position where there is no material.

[0053] In summary, the horizontal aerobic organic waste treatment machine for directional and quantitative oxygen supply provided in this application is based on traditional horizontal aerobic fermentation treatment equipment for organic waste. Several air supply holes are opened on the hollow support rod of the ribbon agitator (or paddle agitator) of the traditional horizontal aerobic fermentation treatment equipment for organic waste. These air supply holes are arranged sequentially and at intervals along the length of the hollow support rod, and are located on the side of the hollow support rod opposite to the stirring direction. Furthermore, this application adds an adjustable rotary air intake valve to the side of the stirring shaft at the follower end. By adjusting the deflection angle of the rotary air intake channel on the rotary air intake valve, the air supply holes on the hollow support rod of the horizontal aerobic organic waste treatment machine are controlled to allow air to enter within a specific rotation range, achieving directional air intake. This solution can be used to cope with different material densities forming different accumulation patterns during the stirring process, ensuring that the horizontal aerobic fermentation treatment equipment for organic waste is always under suitable oxygen supply conditions during the biological treatment of organic waste. In addition, this application also uses an electrical control system with a programmable logic controller (PLC) to collect the operating parameters of organic waste material detected by the detection instruments inside the equipment during the aerobic treatment process, and to regulate the output of the gas supply equipment by frequency conversion to achieve quantitative gas supply, so that the horizontal organic waste aerobic fermentation treatment equipment is always in a condition suitable for the growth of microbial agents and enzyme preparations during the aerobic fermentation process of organic waste.

[0054] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0055] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
