Description

Technical Field

[0001] This invention relates to the technical field of aerobic fermentation treatment devices for organic waste, and in particular to a multi-unit modular nanomembrane non-tumbled continuous fermentation device. Background Technology

[0002] Aerobic fermentation of organic waste is an effective way to treat organic waste such as agricultural straw and livestock manure. Through the metabolic activities of microorganisms under aerobic conditions, organic matter is converted into humic fertilizer. Common fermentation devices consist of a tank for containing materials, a ventilation system, and turning and turning machinery. Since oxygen diffuses slowly in statically piled materials and deep materials have difficulty contacting air, turning and turning are necessary to ensure that the materials come into full contact with oxygen in order to avoid rancidity and stench caused by anaerobic fermentation. Existing technologies include continuous fermentation devices using nanofilm, which typically consist of multiple parallel fermentation units, an aeration network laid at the bottom, a nanocomposite membrane covering the material surface, and a PLC intelligent control system. The nanocomposite membrane allows small molecules such as oxygen and water vapor to pass through due to its microporous structure, while retaining odor molecules such as ammonia and hydrogen sulfide. Each unit is supplied with gas through a centralized pipeline network, and the control system automatically adjusts the air volume according to the temperature and oxygen concentration, enabling modular continuous feeding and discharging, and essentially eliminating the need for mechanical turning and turning throughout the process. However, during long-term operation, it was found that the above-mentioned device still has obvious defects in insufficient deep oxygen supply; the material is piled up in a thick static layer, and oxygen is only supplied from the bottom upwards. The transmission path is long and affected by moisture content and density. The oxygen concentration in the upper and central areas of the pile is consistently low, resulting in local anaerobic conditions. The anaerobic environment leads to incomplete decomposition of organic matter, accumulation of organic acids, and odor escape, which in turn inhibits aerobic bacteria and prolongs fermentation time. In order to ensure the composting effect, it is often necessary to turn the pile halfway or significantly increase the air volume during operation. The root cause of this problem is that the single external covering and bottom centralized air supply method cannot form a uniform oxygen supply throughout the entire depth of the pile. There is a structural contradiction between the oxygen demand and oxygen supply of the deep material, which leads to limitations.

[0003] To address these issues, this invention proposes a multi-unit modular nanomembrane non-tumbled continuous fermentation device. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a multi-unit modular nanofilm non-tumbled continuous fermentation device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-unit modular nanofilm non-tumbled continuous fermentation device, comprising: a fermentation tank, an aeration pipe and a nanocomposite membrane; the aeration pipe is laid at the bottom of the fermentation tank for supplying air into the material; the nanocomposite membrane covers the fermentation tank and coats the surface of the fermented material to allow oxygen and water vapor to pass through while trapping odor molecules. The fermentation material in the fermentation tank is provided with nano-spacer membranes arranged at intervals along the vertical direction to separate the material into multiple layers to improve oxygen distribution. The fermentation tank is also equipped with an oxygenation detection mechanism, which has a sensor that can be inserted into the fermentation material to detect the fermentation state of the material and replenish air into the material according to the detection results.

[0006] Preferably, the detection and oxygenation mechanism includes a moving block, a detection block, and an injection pipe; a moving rail is bolted to the fermentation tank; the moving block is slidably connected to the moving rail, a moving wheel is rotatably connected to the moving block, and a moving motor is fixedly connected to the moving block to drive the moving wheel to rotate; a detection hole is opened on the fermentation tank, and a blocking block is rotatably connected to the fermentation tank to block the detection hole; a torsion spring is connected between the blocking block and the fermentation tank. A lifting block is mounted on the moving block; the detection block is slidably connected to the lifting block; a telescopic motor is fixedly connected to the lifting block; the output end of the telescopic motor is connected to a lead screw that is threaded into the detection block; a detection sensor is fixedly connected to the detection block; the injection pipe is mounted on the detection block; the injection pipe is connected to the aeration pipe through a hose and is controlled by a solenoid valve.

[0007] Preferably, a vertical guide rail is fixed on the moving block; the lifting block is slidably connected to the vertical guide rail; a rack is installed on the vertical guide rail; a lifting motor is fixedly connected to the lifting block; and a vertical gear that meshes with the rack on the vertical guide rail is fixedly connected to the output end of the lifting motor.

[0008] By moving the moving block horizontally along the moving rail and the lifting block vertically raising and lowering, the detection block can reach multiple detection holes within different lengths and heights of the fermentation tank. This allows for automatic detection of the material status in different layers and locations, as well as targeted oxygenation and liquid replenishment, without overturning or throwing the material. This ensures that the material maintains suitable oxygen supply and nutrient environment throughout the entire fermentation cycle, further improving the fermentation efficiency and degradation rate of organic waste.

[0009] Preferably, the fermentation tank has opening slots spaced vertically on its side; an opening sealing block is rotatably connected to the inner wall of the fermentation tank; the opening sealing block is used to seal the opening slots; and a torsion spring is also connected between the opening sealing block and the fermentation tank.

[0010] Preferably, a storage frame is fixedly connected to the lifting block; a push-in block is slidably connected to the bottom of the storage frame; a push-in motor is fixedly connected to the storage frame, and a pair of rotating rollers are rotatably connected to the storage frame; a rotating belt is sleeved on the pair of rotating rollers; the push-in block is fixedly connected to the rotating belt; the output end of the push-in motor is connected to the rotating rollers; the combination of the support rod and the nano-spacer membrane is stacked vertically in the storage frame; the support rod and the nano-spacer membrane in the storage frame can be inserted into the fermentation tank from the opening slot on the fermentation tank; and a support step is provided in the fermentation tank.

[0011] Preferably, the nano-spacer membrane has a double-layer structure, with support rods fixedly connected to both sides of the nano-spacer membrane; and an air passage is provided in the middle of the double-layer nano-spacer membrane.

[0012] Preferably, the support rod has a connecting groove; the connecting groove extends through the end of the support rod and is connected to the ventilation channel on the nano-spacer membrane.

[0013] By using a lifting block to move the storage frame up and down to different heights of the opening slots, the nano-spacer membranes can be pushed layer by layer into different vertical positions of the fermentation material in sequence. This allows for the automatic laying of multiple layers of spacer membranes without turning or throwing the material or removing the nano-composite membranes. This creates multiple independent fermentation zones in the vertical direction, further improving the uniform distribution of oxygen within the material and increasing the efficiency of aerobic fermentation.

[0014] Preferably, a support member is fixedly connected inside the ventilation channel; the support member supports the ventilation channel and prevents the nano-spacer membrane from being crushed.

[0015] In this invention, a support member is fixedly connected inside the ventilation channel, forming multiple support points between the double-layer nano-spacer membrane. When the gravity of the material above acts on the nano-spacer membrane, the support member effectively withstands the pressure, preventing the double-layer nano-spacer membrane from being crushed or stuck together under the pressure of the material, thus preventing blockage of the ventilation channel and ensuring that the ventilation channel remains unobstructed throughout the entire fermentation cycle of the material. A connecting groove passes through the end of the support rod and is connected to the ventilation channel, allowing the airflow entering from the end of the support rod to be smoothly introduced into the ventilation channel, realizing continuous gas supply inside the nano-spacer membrane, thereby further improving the oxygen supply conditions in the deep areas of the material and enhancing the aerobic fermentation efficiency.

[0016] The beneficial effects of this invention are: 1. This invention enables the detection block to reach multiple detection holes within different lengths and heights of the fermentation tank by moving the moving block horizontally along the moving track and by raising and lowering the lifting block vertically. This allows for the automatic detection of material status and targeted oxygenation and liquid replenishment in different layers and locations without overturning or throwing the material. This ensures that the material maintains suitable oxygen supply and nutrient environment throughout the fermentation cycle, further improving the fermentation efficiency and degradation rate of organic waste.

[0017] 2. This invention uses a lifting block to move the storage frame up and down to different heights of the opening slots, allowing the nano-spacer membranes to be pushed layer by layer into different vertical positions of the fermentation material in sequence. This automatically completes the laying of multiple layers of spacer membranes without turning or throwing the material or removing the nano-composite membranes, so that the material forms multiple independent fermentation zones in the vertical direction, further improving the uniform distribution of oxygen inside the material and increasing the efficiency of aerobic fermentation.

[0018] 3. The ventilation channel of the present invention is fixedly connected with a support member, which forms multiple support points between the double-layer nano-spacer membrane; when the gravity of the material above acts on the nano-spacer membrane, the support member effectively bears the pressure, preventing the double-layer nano-spacer membrane from being crushed or stuck together under the pressure of the material, thus preventing the ventilation channel from being blocked, and ensuring that the ventilation channel remains unobstructed throughout the entire fermentation cycle of the material.

[0021] The technical solutions of 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.

[0022] Example 1: Refer to the appendix of the instruction manual. Figures 1 to 9 A multi-unit modular nanofilm non-tumbled continuous fermentation device includes: a fermentation tank 1, an aeration pipe 11, and a nanocomposite membrane 12; the aeration pipe 11 is laid at the bottom of the fermentation tank 1 to supply air into the material; the nanocomposite membrane 12 covers the fermentation tank 1 and coats the surface of the fermentation material to allow oxygen and water vapor to pass through while trapping odor molecules. In the fermentation material in fermentation tank 1, nano-spacer membranes 13 are arranged at intervals along the vertical direction to separate the material into multiple layers to improve oxygen distribution. Fermentation tank 1 is also equipped with a detection and oxygenation mechanism. The detection and oxygenation mechanism has a sensor that can be inserted into the fermentation material to detect the fermentation state of the material and replenish air into the material according to the detection results.

[0023] In this invention, the oxygenation detection mechanism includes a moving block 21, a detection block 22, and an injection pipe 23; a moving rail 24 is bolted onto the fermentation tank 1; the moving block 21 is slidably connected to the moving rail 24, a moving wheel is rotatably connected to the moving block 21, and a moving motor 25 is fixedly connected to the moving block 21 to drive the moving wheel to rotate; a detection hole 26 is opened on the fermentation tank 1, and a blocking block 27 is rotatably connected to the fermentation tank 1 to block the detection hole 26; a torsion spring is connected between the blocking block 27 and the fermentation tank 1. A lifting block 28 is installed on the moving block 21; a detection block 22 is slidably connected to the lifting block 28; a telescopic motor 29 is fixedly connected to the lifting block 28; the output end of the telescopic motor 29 is connected to a lead screw 3 that is threadedly engaged with the detection block 22; a detection sensor 31 is fixedly connected to the detection block 22; an injection pipe 23 is installed on the detection block 22; the injection pipe 23 is connected to the aeration pipe 11 through a hose and is controlled by a solenoid valve.

[0024] In this invention, a vertical guide rail 4 is fixed on the moving block 21; a lifting block 28 is slidably connected to the vertical guide rail 4; a rack is installed on the vertical guide rail 4; a lifting motor 41 is fixedly connected to the lifting block 28; and a vertical gear 42 that meshes with the rack on the vertical guide rail 4 is fixedly connected to the output end of the lifting motor 41.

[0025] During operation, the organic material to be fermented is placed in the fermentation tank 1, and the aeration pipe 11 continuously or intermittently supplies air to the bottom of the material. At the same time, nano-spacer membranes 13 are laid at intervals in the vertical direction of the material to divide the material into multiple layers, improving the permeation and distribution of oxygen inside the material. The top of the fermentation tank 1 is covered with a nano-composite membrane 12, which allows oxygen and water vapor to pass through while trapping odor molecules, thus achieving continuous aerobic fermentation. In this invention, when detecting the fermentation state of the material, the moving motor 25 drives the moving wheel to rotate, causing the moving block 21 to move horizontally along the moving rail 24 to the preset detection hole 26 position; the lifting motor 41 on the moving block 21 drives the lifting block 28 to rise and fall along the vertical guide rail 4 through the meshing of the vertical gear 42 and the rack, so that the detection block 22 is aligned with the detection hole 26 on the fermentation tank 1; the telescopic motor 29 pushes the detection block 22 into the material through the lead screw 3, pushing the detection sensor 31 and the injection pipe 23 into the detection hole 26, thereby causing the sealing block 27 to rotate and move under the action of external force, and the detection block 22 brings the detection sensor 31 and the injection pipe 23 into the material at different depths; the detection sensor 31 includes a temperature sensor, a humidity sensor and an oxygen concentration sensor, and the detection sensor 31 collects the fermentation state parameters such as the temperature, humidity and oxygen concentration of the material in real time and transmits the data to the controller; In this invention, when the detection sensor 31 detects that the local oxygen concentration of the material is lower than the set value or that microbial nutrients need to be supplemented, the solenoid valve is opened, so that the gas in the aeration pipe 11 is directly injected into the required part of the material through the hose and the injection pipe 23, so as to achieve fixed-point and quantitative oxygenation; after the injection is completed, the telescopic motor 29 reverses to drive the detection block 22 to exit the material, and the sealing block 27 re-seals the detection hole 26 under the action of the torsion spring and its own gravity, and the moving block 21 returns to the standby position or moves to the next detection point; In this invention, by moving the moving block 21 horizontally along the moving rail 24 and by lifting the lifting block 28 vertically, the detection block 22 can reach multiple detection holes 26 within different lengths and heights of the fermentation tank 1. This allows for the automatic detection of material status and targeted oxygenation and liquid replenishment at different layers and locations without overturning or throwing the material. This ensures that the material maintains suitable oxygen supply conditions and a nutrient environment throughout the entire fermentation cycle, further improving the fermentation efficiency and degradation rate of organic waste.

[0026] In this invention, the side of the fermentation tank 1 is provided with opening slots 43 at intervals on the upper and lower sides; an opening sealing block 44 is rotatably connected to the inner wall of the fermentation tank 1; the opening sealing block 44 is used to seal the opening slots 43; a torsion spring is also connected between the opening sealing block 44 and the fermentation tank 1.

[0027] In this invention, a storage frame 5 is fixedly connected to the lifting block 28; a push-in block 51 is slidably connected to the bottom of the storage frame 5; a push-in motor 52 is fixedly connected to the storage frame 5, and a pair of rotating rollers 53 are rotatably connected to the storage frame 5; a rotating belt 54 is sleeved on the pair of rotating rollers 53; the push-in block 51 is fixedly connected to the rotating belt 54; the output end of the push-in motor 52 is connected to the rotating rollers 53; the combination of the support rod 45 and the nano-spacer membrane 13 is stacked and stored in the storage frame 5; the support rod 45 and the nano-spacer membrane 13 in the storage frame 5 can be inserted into the fermentation tank 1 from the opening slot 43 on the fermentation tank 1; a support step is provided in the fermentation tank 1.

[0028] In this invention, the nano-spacer membrane 13 has a double-layer structure, and support rods 45 are fixedly connected to both sides of the nano-spacer membrane 13; a ventilation channel 46 is provided in the middle of the double-layer nano-spacer membrane 13.

[0029] In this invention, a connecting groove 6 is provided on the support rod 45; the connecting groove 6 passes through the end of the support rod 45 and is connected to the ventilation channel 46 on the nano-spacer membrane 13.

[0030] In this invention, when the nano-spacer membrane 13 is laid in layers in the fermentation tank 1, the moving motor 25 drives the moving wheel to rotate, which drives the moving block 21 to move horizontally along the moving rail 24. At the same time, the lifting motor 41 drives the lifting block 28 to rise and fall along the vertical guide rail 4 through the meshing of the vertical gear 42 and the rack, so that the outlet of the storage frame 5 is aligned with the opening slot 43 at the corresponding height on the fermentation tank 1. In this invention, multiple assemblies consisting of support rods 45 and nano-spacer membranes 13 are pre-stacked in the storage frame 5. When the storage frame 5 is aligned with the target opening slot 43, the push motor 52 is started, driving the rotating roller 53 and the rotating belt 54 to move. The rotating belt 54 drives the push block 51 to move along the bottom of the storage frame 5 towards the opening slot 43. The push block 51 pushes the bottommost support rod 45 and nano-spacer membrane 13 assembly, causing its front end to push open the opening sealing block 44. After being subjected to force, the opening sealing block 44 rotates around the hinge axis to make room inside the fermentation tank 1. The push block 51 continues to push, pushing the support rod 45 and nano-spacer membrane 13 assembly from the opening slot 43 into the material layer inside the fermentation tank 1. The two ends of the support rod 45 rest on the support steps set on the inner wall of the fermentation tank 1. In this invention, after the combination of support rod 45 and nano-spacer membrane 13 is completely pushed into fermentation tank 1, push motor 52 rotates in the opposite direction, driving push block 51 back to its original position in storage frame 5; opening sealing block 44 automatically resets under gravity or elastic force, resealing opening slot 43 to prevent gas and heat from escaping from opening slot 43 during fermentation; the remaining stacked combinations fall under gravity, with the bottom set falling into the pushing position of push block 51, waiting for the next layer to be laid. In this invention, the nano-spacer membrane 13 adopts a double-layer structure, with support rods 45 fixedly connected to both sides, so that a through ventilation channel 46 is formed between the two layers of nano-spacer membrane 13; when the combination of support rods 45 and nano-spacer membrane 13 is pushed into the material layer in the fermentation tank 1, the two ends of the support rods 45 are placed on the support steps on the inner wall of the fermentation tank 1, and the nano-spacer membrane 13 is laid flat between the material layer areas. In this invention, during the upward process of the air supplied by the aeration pipe 11, part of the gas directly permeates upward through each layer of material, while the other part of the gas enters the material layer below the nano-spacer membrane 13 and then enters the ventilation channel 46 between the double-layer nano-spacer membranes 13 through the connecting groove 6 opened on the support rod 45. The gas diffuses laterally inside the nano-spacer membrane 13 along the ventilation channel 46 and escapes evenly from the upper and lower surfaces of the double-layer nano-spacer membrane 13, respectively entering the adjacent upper and lower material zones, thereby greatly increasing the contact area between oxygen and material and making the oxygen distribution in the material layer zone more uniform. In this invention, the lifting block 28 drives the storage frame 5 to rise and fall to the opening slots 43 at different heights, so that the nano-spacer membrane 13 can be pushed into different vertical positions of the fermentation material in sequence. Thus, without turning the material over or removing the nano-composite membrane 12, the laying of multiple layers of spacer membranes is automatically completed, so that the material forms multiple independent fermentation zones in the vertical direction, further improving the uniform distribution of oxygen inside the material and improving the aerobic fermentation efficiency.

[0031] Example 2: Based on Example 1, refer to the appendix of the instruction manual. Figures 1 to 9 In this invention, a support member 55 is fixedly connected inside the ventilation channel 46; the support member 55 supports the ventilation channel 46 and prevents the nano-spacer membrane 13 from being crushed.

[0032] In this invention, a support member 55 is fixedly connected inside the ventilation channel 46, and the support member 55 forms multiple support points between the double-layer nano-spacer membrane 13. When the gravity of the material above acts on the nano-spacer membrane 13, the support member 55 effectively bears the pressure, preventing the double-layer nano-spacer membrane 13 from being crushed or stuck together under the pressure of the material, thus preventing the ventilation channel 46 from becoming blocked, and ensuring that the ventilation channel 46 remains unobstructed throughout the entire fermentation cycle of the material. The connecting groove 6 passes through the end of the support rod 45 and is connected to the ventilation channel 46, so that the airflow entering from the end of the support rod 45 can be smoothly introduced into the ventilation channel 46, realizing continuous air supply inside the nano-spacer membrane 13, thereby further improving the oxygen supply conditions in the deep area of ​​the material and improving the aerobic fermentation efficiency.
