Description

Technical Field

[0001] The present application relates to the technical field of organic waste biological treatment equipment, and in particular to an organic waste aerobic treatment machine, and specifically to a horizontal organic waste aerobic treatment machine that realizes directional and quantitative oxygen supply. Background Art

[0002] Organic waste is rich in organic matter. The use of microorganisms to decompose and transform organic matter under aerobic conditions can realize the resource utilization of organic waste. The core factors affecting the efficiency of aerobic fermentation include microorganisms and environmental conditions, and the fermentation temperature and oxygen content in the environmental conditions are the most important factors affecting the effect of aerobic fermentation. In the process of using high-temperature aerobic fermentation technology to treat organic waste, the garbage disposal machine automatically runs according to the set process parameters and procedures under the PLC logic control of its electronic control system. The entire production process goes through various stages such as feeding, temperature start, fermentation, drying, cooling and discharging, and finally produces fermented products. During the high-temperature aerobic fermentation process, it is necessary to introduce air into the materials in the garbage disposal machine. The purpose of introducing air is twofold. One is to provide the materials with the temperature and oxygen conditions required in the aerobic fermentation and drying process; the other is to serve as a carrier for the water vapor (water vaporization in the material) that escapes during the fermentation and drying process of the material, and finally it is discharged through the dust removal and exhaust system.

[0003] Traditional aerobic waste fermentation treatment machines usually design an "oxygen supply system" to introduce air into the material. This "oxygen supply system" is generally implemented in the following two ways:

[0004] 1. Directly blown in by the air supply fan: The horizontal organic waste aerobic fermentation treatment machine uses an air supply fan to directly blow in air. Due to the high density of the material and the low air pressure of the air supply fan, the air permeability is poor, and the organic waste material cannot be fully oxygenated, resulting in a low oxygen content in the material, and microorganisms and enzyme preparations cannot grow quickly, and the treatment efficiency is low. In addition, the air volume of the air supply fan is large, the flow rate is high, and the air intake and exhaust of the chamber are easily short-circuited, which will take away a lot of heat in the horizontal organic waste aerobic fermentation treatment machine, resulting in high treatment energy consumption.

[0005] 2. Blowing in through the air supply hole on the central stirring shaft jacket: The horizontal organic waste aerobic fermentation treatment machine that uses the air supply hole on the central stirring shaft jacket to blow in is achieved through the air supply hole on the stirring shaft jacket located in the center. Figure 1, the central agitator shaft jacket is provided with an air supply hole 01, and the arrow direction in the figure indicates the air supply path. When the horizontal organic waste aerobic fermentation treatment machine treats organic waste materials, the loading capacity is usually 70-75% of the total volume, which means that the material has different thicknesses at different distances from the central agitator shaft. The material thickness from the central axis to the bottom of the equipment in the traditional horizontal organic waste aerobic fermentation treatment machine is much higher than the material thickness from the central axis to the upper part of the equipment. When air is ventilated to the material through the central axis jacket hole, the material thickness in each direction of the central axis is inconsistent, resulting in different resistances in each direction. According to the principle of minimum resistance in the ventilation path, most of the gas escapes from the top of the material and cannot penetrate into the bottom material, and cannot fully replenish oxygen, resulting in uneven oxygen content in the material, and microorganisms and enzyme preparations cannot grow rapidly, resulting in low treatment efficiency.

[0006] It can be seen that in the traditional aerobic waste fermentation treatment machine, whether the material is oxygenated by blowing directly from the air supply fan or by blowing from the air supply hole on the jacket of the central stirring shaft, there are problems such as poor aeration penetration and inability to fully supply oxygen, thus making it difficult to efficiently promote fermentation. Therefore, it is necessary to propose a new technical solution to solve the problems existing in the prior art. Summary of the invention

[0012] Furthermore, the fixed valve body is a disc structure, the rotationally adjustable air inlet channel is an arc-shaped channel opened on the disc surface near the edge of the disc structure, and the fixed valve body is provided with one or more rotationally adjustable air inlet channels; the rotating valve body is a disc structure, and the rotating valve body is provided with a plurality of air supply channels radially opened with its center as the center, and when the rotating valve body rotates along with the stirring shaft, it can drive the air supply channels thereon to rotate relative to the rotationally adjustable air inlet channel, thereby realizing the conduction or cutoff of the air supply channels and the rotationally adjustable air inlet channel.

[0013] Furthermore, the arc-shaped groove is a half arc opened on the fixed valve body disk; three air supply channels are provided on the rotating valve body, and the three air supply channels are evenly distributed on the half disk of the rotating valve body.

[0016] Furthermore, a stainless steel pipe is disposed outside the stirring shaft, and the gap between the stirring shaft and the stainless steel pipe forms the air channel. The air supply channel on the rotary valve body is connected to the inner cavity gas of the hollow support rod through the air channel, and the gas between two adjacent hollow support rods on the same side of the stirring shaft is connected through an extended pipe.

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

[0018] 1. The present application forms an air channel on the stirring shaft and connects the air channel with the inner cavity of the hollow support rod, so that the air sent into the air channel of the stirring shaft can be directly transported to the stirring area, thereby improving the oxygen transfer efficiency. A plurality of air supply holes are opened on the side wall of the hollow support rod facing away from the stirring direction, so that oxygen can be directly supplied to the material during the stirring process, thereby enhancing the oxygen permeability and enabling the oxygen to be more evenly distributed in the fermentation material. The air supply holes are located in a direction not facing the movement of the material, so that there is no pressure contact with the material, which can prevent the material from being blocked during operation. In addition, the structural design of the fixed valve body and the rotating valve body of the rotary air inlet valve can dynamically control the gas when the stirring shaft rotates. Supply, by adjusting the rotation angle of the rotating adjusting air inlet channel, the timing and position of the gas supply can be accurately controlled. When the hollow support rod rotates to the target rotation range, the air supply hole thereon is connected to the gas in the rotating adjusting air inlet channel, thereby realizing directional and quantitative oxygen supply, which can reduce the loss of oxygen and improve the utilization efficiency of oxygen.

Furthermore, through the structural design of the rotary air inlet valve, the stirring shaft and the hollow support rod, when the rotation angle of the rotary air inlet valve is adjusted, the air supply holes on the hollow support rod can be controlled to supply air in a specific rotation range, which is used to cope with different stacking forms formed by different material densities during the stirring process, so that the horizontal organic waste aerobic treatment machine is always in oxygen supply conditions suitable for the growth of microbial agents and enzyme preparations during the biological process of treating organic waste.

[0020] 3. The detachable connection design between the air intake angle adjustment disk and the valve shell in the present application can facilitate the rotation adjustment operation of the air intake angle adjustment disk, and is also convenient for maintenance and replacement of the air intake angle adjustment disk, reducing maintenance time and cost; in addition, the rotation-adjustable air intake angle adjustment disk can adjust the position of the rotation-adjustable air intake channel on the fixed valve body, and cooperate with the rotating valve body to achieve more precise air supply angle adjustment, ensuring that the air supply hole and the rotation-adjustable air intake channel achieve gas conduction in the target air supply area, and can cope with different stacking forms formed by different material densities during the mixing process.

[0021] 4. The present application can achieve more accurate gas distribution through the half-circular arc groove on the fixed valve body and the three evenly distributed air supply holes on the rotating valve body; the air supply holes on the rotating valve body are radially opened with the center of the rotating valve body as the center. This design helps to improve the efficiency of gas flow and reduce the resistance of gas during transportation; the disc structure of the fixed valve body and the rotating valve body simplifies the mechanical design, making the structure of the entire system more compact and easy to install and maintain; in addition, the conduction or cutoff of the air supply hole and the rotating regulating air inlet groove can be dynamically adjusted according to the rotation of the stirring shaft, which helps to optimize the gas The contact between the rotary valve body and the organic waste material can improve the efficiency of aerobic fermentation and reduce oxygen loss. When the rotary valve body rotates with the stirring shaft, it can quickly respond to changes in the material pile, adjust the air supply in time, and improve the response speed of the system. Through this dynamic adjustment of air supply, it can adapt to different fermentation conditions and material characteristics. By adjusting the relative position of the air supply channel and the rotary adjustment air inlet channel, accurate air supply for different material stacking forms and different fermentation stages can be achieved. By accurately controlling the gas supply, the instability of the fermentation process caused by uneven or excessive air supply can be reduced, thereby improving the stability and reliability of the entire system.

Without departing from the technical concept disclosed in this application, changes in these relative positional relationships should also be considered as the scope of this application.

[0038] The present application provides a horizontal aerobic organic waste treatment machine that realizes directional and quantitative oxygen supply. Compared with the existing horizontal aerobic organic waste fermentation treatment machine, which has the problems of poor penetration, low oxygen content in the material, and high treatment energy consumption by directly blowing in the air supply fan, compared with the existing horizontal aerobic organic waste fermentation treatment machine, which has the problems of poor penetration, low oxygen content in the material, and high treatment energy consumption by blowing in the air supply hole on the central stirring shaft jacket due to the inconsistent thickness of the material in each direction of the central axis, the resistance in each direction is different, causing most of the gas to escape from the top of the material and unable to penetrate into the bottom material, unable to fully supply oxygen, causing the material In order to solve the problems of uneven oxygen content, inability of microorganisms and enzyme preparations to grow quickly, and low treatment efficiency, the present application uses a rotary air intake valve with a variable air supply angle and an air intake hole opened on the hollow support rod on the stirring shaft facing away from the stirring direction, so that the intake of fresh air is controlled by the corresponding conduction and cutoff of the arc slotted air intake channel on the fixed valve body and the air supply channel on the rotary valve body, which can ensure that the air supply holes on the hollow support rod supply air when contacting the material and stop supplying air after leaving the material, thereby preventing the air supply holes on the hollow support rod from being in the upper part without material, causing oxygen loss due to the lack of material resistance. The structural principle of the horizontal organic waste aerobic treatment machine that can achieve directional and quantitative oxygen supply is described in detail below in conjunction with the accompanying drawings.

[0039] See also Figure 2The present application provides a horizontal aerobic organic waste treatment machine for realizing directional quantitative oxygen supply, which mainly comprises: a stirring device arranged in a casing, the stirring device comprises a stirring shaft 1 and a stirring sheet structure installed on the stirring shaft 1 through a hollow support rod 2, an air passage 6 connected to the inner cavity of the hollow support rod 2 is formed on the stirring shaft 1, a plurality of air supply holes 3 are provided on the side wall of the hollow support rod 2 facing away from the stirring direction, a rotary air inlet valve 8 is installed at one end of the stirring shaft 1, the rotary air inlet valve 8 comprises a valve casing 9 and a fixed valve body 11 and a rotary valve body 13 arranged in the valve casing 9, and a rotary valve body 13 is provided. The rotary valve body 13 is integrally connected to the stirring shaft 1, and one or more air supply channels 14 are provided on the rotary valve body 13, and the air supply channels 14 are connected to the air channel 6. A rotary adjustable air inlet channel 12 is provided on the fixed valve body 11, and the rotary adjustable air inlet channel 12 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 housing 9 through an air inlet angle adjustment disk 15. By adjusting the rotation angle of the rotary adjustable air inlet channel 12, when the hollow support rod 2 is rotated to the target rotation range, the air supply hole 3 thereon is connected to the rotary adjustable air inlet channel 12 for gas.

[0040] The above scheme can be used to adjust the rotary air inlet valve 8 according to the different stacking forms (material stirring stacking angles) formed by different material densities during the mixing process. During adjustment, remove the air inlet angle adjustment disk 15 and then adjust the fixed valve body 11 so that the rotary adjustment air inlet channel 12 thereon is in the target rotation position, and then install the fixed air inlet angle adjustment disk 15 to fix it. During the mixing process, air can be supplied intermittently according to the target angle, thereby ensuring that the air supply hole 3 works when it contacts the material and stops supplying air when it leaves the material, ensuring that the material can be fully oxygenated, so that the horizontal organic waste aerobic treatment machine is always in conditions suitable for the growth of microbial agents and enzyme preparations during the biological treatment process of organic waste, thereby producing high-quality fermentation products, reducing energy consumption, and reducing oxygen loss. In addition, see Figure 6 A plurality of air supply holes 3 are provided on the side wall of the hollow support rod 2 facing away from the stirring direction so that oxygen can be directly supplied to the material during the stirring process, thereby enhancing the oxygen permeability and allowing the oxygen to be more evenly distributed in the fermentation material. The air supply holes 3 are located in a direction not facing the movement direction of the material, so that there is no pressure contact with the material, thereby preventing the air supply holes 3 from being blocked by the material during operation.

[0041] In a preferred embodiment of the present application, a detection module is provided in the casing, and the detection module includes a mixing bin pressure detector, an oxygen content detector, a temperature sensor and a moisture detector. The detection module can be connected to the control system signal, and the control system can detect the operating parameters of the organic waste material in the casing during the aerobic treatment process through the detection module, and then frequency-control the output of the gas supply equipment, that is, realize quantitative gas delivery. The control system can be an electrical control panel, which completes the entire biological treatment process according to the program pre-stored in the programmable controller PLC. After the fermentation work starts, the PLC collects the parameters of the process in real time through various detection instruments in the system. The PLC can automatically frequency-control the air supply of the air supply fan or stop it according to the real-time data transmitted by the detection instrument.

[0042] In a preferred embodiment of the present application, see Figure 2 The air supply device in the present application may include an air supply fan 18 and an air storage tank 19, and the air supply fan 18 is used to transport the gas in the air storage tank 19 to the air inlet end of the rotary air inlet valve 8. The air storage tank 19 can also be directly replaced with an oxygen tank according to application requirements.

[0043] In a preferred embodiment of the present application, see Figure 3 , 4 One end of the valve housing 9 of the rotary air inlet valve 8 is fastened to the passive end of the stirring shaft 1 by a fixing bolt 10, and the other end of the valve housing 9 is provided with a mounting hole seat for installing the air inlet angle adjustment disk 15, and the air inlet angle adjustment disk 15 is detachably connected to the mounting hole seat by a connecting bolt 16, and a valve air inlet pipe 17 is passed through the air inlet angle adjustment disk 15, and the valve air inlet pipe 17 is connected to the fixed valve body 11; after removing the connecting bolt 16, rotating the fixed valve body 11 can make the rotary adjustment air inlet channel 12 rotate about the central axis of the mounting hole seat, so that when the hollow support rod 2 is rotated into the material pile body, the air supply hole 3 thereon is connected to the rotary adjustment air inlet channel 12. This detachable connection design not only facilitates the rotation and adjustment operation of the air inlet angle adjustment disk 15, but also facilitates the maintenance and replacement of the air inlet angle adjustment disk 15, reducing maintenance time and cost.

[0044] In a preferred embodiment of the present application, the above-mentioned fixed valve body 11 is a disc structure, and the rotation-adjusting air inlet channel 12 is a section of an arc-shaped channel opened on the disc surface near the edge of the disc structure. One or more rotation-adjusting air inlet channels 12 are opened on the fixed valve body 11, such as Figure 8 The fixed valve body 11 is provided with two rotating air inlet channels 12. Correspondingly, the rotating valve body 13 is a disc structure, and the rotating valve body 13 is provided with a plurality of air delivery channels 14 radially with its center as the center. Figure 8When the rotary valve body 13 rotates along with the stirring shaft 1, it can drive the air supply channel 14 thereon to rotate relative to the rotary regulating air inlet channel 12, thereby realizing the conduction or cutoff of the air supply channel 14 and the rotary regulating air inlet channel 12.

[0045] The present application can achieve more precise adjustment of the air supply angle by adjusting the position of the rotary adjustment air inlet channel 12 on the fixed valve body 11, and then cooperating with the air supply channel 14 on the rotary valve body 13, thereby ensuring that the air supply hole 3 and the rotary adjustment air inlet channel 12 achieve gas conduction in the target air supply area, and can cope with different stacking forms formed by different material densities during the mixing process. The air supply hole 3 can be dynamically adjusted according to the position of the material pile, thereby enhancing the adaptability of the system. The air supply angle can also be flexibly adjusted according to the characteristics of different materials and fermentation requirements, thereby reducing oxygen loss and improving oxygen utilization.

[0046] In a specific embodiment, see Figure 4 , the arc-shaped groove is a half-circle arc opened on the disk of the fixed valve body 11; three air supply channels 14 are arranged on the rotary valve body 13, and the three air supply channels 14 are evenly distributed on the half-circle disk of the rotary valve body 13. The present application can achieve more accurate gas distribution through the half-circle arc groove on the fixed valve body 11 and the three evenly distributed air supply channels 14 on the rotary valve body 13; the air supply channels 14 on the rotary valve body 13 are radially opened with the center of the rotary valve body 13 as the center. This design helps to improve the efficiency of gas flow and reduce the resistance of gas during transportation. Of course, in the specific production and application process, the size and position of the arc-shaped groove opened on the fixed valve body 11 can be customized according to the material requirements in the mixing bin and the shape of the material pile after mixing, and the number, position and size of the air supply channels 14 opened on the rotary valve body 13 can be customized accordingly.

[0047] In the specific manufacturing and installation process, the active end of the stirring shaft 1 is installed on the casing through an active support bearing, the active end of the stirring shaft 1 is connected to the stirring drive motor, and the passive end of the stirring shaft 1 is installed on the casing through a passive support bearing. The passive end of the stirring shaft 1 forms an extension section outward, and the rotary valve body 13 is formed in the extension section. Figure 2 , 5 The above stirring sheet structure can be a spiral ribbon 4 or a paddle. The spiral ribbon 4 is a spiral ribbon structure spirally wound around the outer periphery of the stirring shaft 1, and the paddle is a sheet structure. Both the spiral ribbon 4 and the paddle are connected and fixed to the stirring shaft 1 through a hollow support rod 2 arranged along the radial direction of the stirring shaft 1.

[0048] In order to deliver the gas input into the rotary air inlet valve 8 into the hollow support rod 2, during the specific manufacturing process, a stainless steel pipe 5 can be disposed on the outer surface of the stirring shaft 1, and the gap between the stirring shaft 1 and the stainless steel pipe 5 is used as the air channel 6. The air delivery channel 14 on the rotary valve body 13 is connected to the inner cavity gas of the hollow support rod 2 through the air channel 6, and the two adjacent hollow support rods 2 on the same side of the stirring shaft 1 are connected to the gas through the extension pipe 7. Of course, a stainless steel air delivery pipe can also be provided in the air channel 6, and the pipe can be adapted to use stainless steel elbows and other pipe accessories at the bends of the gas delivery path to achieve continuous delivery of the air delivery pipe.

[0049] The horizontal organic waste aerobic treatment machine provided by the present application can improve the oxygen supply in the process of biological aerobic treatment of organic waste, realize uniform oxygen supply, and control the oxygen supply. In addition, the present application can also adjust the air intake angle according to the different stacking angles formed by different material densities during the stirring process to prevent ineffective oxygen supply. The technical solution provided by the present application can improve the efficiency of microorganisms or enzyme preparations in the biological treatment of organic waste, shorten the organic waste treatment time, and improve the quality of fermentation output.

[0050] The specific working process of the horizontal organic waste aerobic treatment machine provided in this application is described in detail below.

[0051] Before the horizontal organic waste aerobic treatment machine provided by the present application works, first, it is necessary to detect the nitrogen source content, moisture content and bulk density of the organic waste, calculate the feed ratio of the organic waste biological treatment equipment by calculating the data of the organic waste, moisture content and carbon source adjustment material, and mix two or more organic waste materials. In an application example, the moisture content of the mixed material is 55-60%, the carbon-nitrogen ratio is 25:1, and the bulk density is 700-900kg / m 3 Then, according to the material characteristics after proportioning, estimate and observe the material stacking angle after stirring, and adjust the air inlet angle adjustment disk 15 according to the material stacking angle. The above work only needs to be adjusted once in the initial stage of operation or after changing the type of garbage to be processed.

[0052] like Figure 7As shown: at this time, the opening and closing of the fresh air intake is controlled by the arc-shaped rotating and adjusting air intake channel 12 on the fixed valve body 11. When the preset pipeline opening in the stirring shaft 1 (i.e., the air channel 6 in the stirring shaft 1) runs to the opening on the lower left side of the fixed valve body 11 (i.e., the arc-shaped rotating and adjusting air intake channel 12), the air channel 6 is connected with the rotating and adjusting air intake channel 12 through the air supply channel 14 on the rotating valve body 13, and oxygen supply to the material begins. When the preset pipeline opening in the stirring shaft 1 runs and rotates to the upper right of the fixed valve body 11, the air supply channel 14 on the rotating valve body 13 does not correspond to the rotating and adjusting air intake channel 12, and the gas delivery is cut off, and the oxygen supply to the material stops. Therefore, the present application can ensure that the air supply hole 3 on the hollow support rod 2 supplies air when it contacts the material, and stops supplying air after leaving the material, so as to prevent the air supply hole 3 on the hollow support rod 2 from being in the upper part without material, and causing oxygen loss due to the lack of material resistance.

[0053] In summary, the present application provides a horizontal aerobic organic waste treatment machine that realizes directional and quantitative oxygen supply. The horizontal aerobic organic waste treatment machine is based on the traditional horizontal aerobic fermentation treatment equipment for organic waste. A plurality of air supply holes are opened on the hollow support rod of the spiral ribbon stirring (or paddle stirring) of the traditional horizontal aerobic organic waste fermentation treatment equipment. The plurality of air supply holes are arranged in sequence along the length direction of the hollow support rod, and the plurality of air supply holes are arranged on the side of the hollow support rod that is away from the stirring direction. In addition, the present application also adds a rotary air intake valve with an adjustable air intake angle on the stirring shaft side of the follower end. By adjusting the deflection angle of the rotary adjustment 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 intake air in a specific rotation range to realize directional air intake. The scheme can be used to cope with different stacking forms formed by different material densities during the stirring process, so that the horizontal aerobic organic waste fermentation treatment equipment is always in a suitable oxygen supply condition during the biological process of treating organic waste.
