Description

Technical Field

[0001] The present invention relates to the technical field of organic waste treatment, and particularly to a horizontal aerobic fermentation reactor, which is applicable to the treatment of organic waste in agriculture and the commercial production of organic fertilizers. Background Art

[0002] With the development of modern agriculture, a large amount of agricultural organic waste such as livestock and poultry manure, tail vegetables, and crop straws generated by planting and animal husbandry has caused serious pollution to the environment during the process of piling and rotting, affecting agricultural development and the rural human settlement environment. Accelerating the use and popularization of aerobic fermentation reactors can not only improve the quality of compost products, but also solve the problems of construction land limitation, reduce construction costs, achieve harmless treatment of waste, facilitate large-scale mechanized production, and is of great significance for the treatment of agricultural non-point source pollution and the resource utilization of organic waste.

[0003] At present, domestic horizontal drum aerobic fermentation reactors are provided with feeding and discharging ports on the rotating cylinder wall, and their disadvantages are mainly manifested in two aspects: First, when feeding or discharging, it is necessary to stop rotating, which is not conducive to normal aerobic fermentation and is likely to cause local anaerobic conditions, generating a large amount of greenhouse gases such as methane; Second, it is impossible to configure an air pipe passing through the cylinder body in the fermentation drum. Only relying on the slow rotation of the cylinder body itself and the action of the baffle, it is easy to cause insufficient aeration, incomplete fermentation, increased greenhouse gas emissions, etc. Summary of the Invention

[0004] In order to solve the existing disadvantages and deficiencies in the treatment of organic waste generated by the livestock and poultry breeding industry, agriculture, etc., the present invention provides a horizontal aerobic fermentation reactor, which solves the problems of poor fermentation and decomposition effect caused by the interruption of feeding and discharging and insufficient aeration of the existing horizontal drum aerobic fermentation reactor, and reduces greenhouse gas emissions.

[0005] The technical solutions adopted are as follows:

[0006] A horizontal aerobic fermentation reactor, comprising a frame and a fermentation drum, a transmission system and a control device disposed on the frame. The transmission system is electrically connected to the control device and is used to support and drive the fermentation drum to rotate. Vertically fixed on the frame are a first end platform and a second end platform which are spaced apart, and the first end platform and the second end platform are disposed at both ends of the fermentation drum, so that both ends of the fermentation drum respectively form a labyrinth seal connection with relative rotation with the first end platform and the second end platform to seal both ends of the fermentation drum. An inlet for installing a feeding device is provided on the upper part of the first end platform, and an outlet for installing a discharging device is provided on the lower part of the second end platform. A plurality of pushing and scraping plates are also provided at intervals on the inner side surface of the fermentation drum, and the plurality of pushing and scraping plates are arranged in a spiral line and are used to stir the internal materials to move forward. An aeration system is further provided along the axial direction of the fermentation drum inside the fermentation drum, and both ends of the aeration system are respectively fixedly connected to the first end platform and the second end platform.

[0007] Further, an annular stationary labyrinth ring is respectively provided at opposite end faces of the first end platform and the second end platform, and movable sealing rings that rotate synchronously with the fermentation drum are provided at both ends of the barrel body of the fermentation drum. The movable sealing rings are nested in the stationary labyrinth rings and form a labyrinth seal with the stationary labyrinth rings.

[0008] Preferably, the fermentation drum has a polyurethane heat insulation layer, and the thickness of the polyurethane heat insulation layer is ≥50 mm.

[0009] More preferably, the plurality of pushing and scraping plates provided on the inner side surface of the fermentation drum are arranged in a multi-start spiral line along its inner wall.

[0010] Preferably, the aeration system includes an aeration fan and a plurality of aeration pipes arranged along the axial direction of the fermentation drum. Solenoid valves for controlling oxygen delivery and a number of aeration holes arranged along the pipe body are provided on the aeration pipes. The aeration pipes are connected by diagonal braces; both ends of the aeration pipes are respectively fixed to the first end platform and the second end platform, one end of the aeration pipe is connected to the aeration fan, and the solenoid valves and the aeration fan are respectively electrically connected to the control device.

[0011] More preferably, the aeration pipes are arranged at the middle and lower positions of the fermentation drum, and three aeration pipes are arranged in parallel and form a triangular cross-sectional structure after being connected by the diagonal braces.

[0012] Preferably, the transmission system includes a driving motor fixed on the frame, a pair of limiting edge wheels and a pair of supporting wheels. An active sprocket is provided on the output shaft of the driving motor. A retaining ring for the edge wheel, a retaining ring for the supporting wheel and a transmission chain are respectively provided on the outer wall of the fermentation drum corresponding to the limiting edge wheel, the supporting wheel and the active sprocket. The limiting edge wheel and the supporting wheel are abutted against the lower sides of both sides of the fermentation drum, and the active sprocket is in meshing transmission with the transmission chain.

[0013] Preferably, the feeding device is a feeding screw conveyor for feeding organic waste raw materials, bacterial agents and auxiliary materials into the fermentation drum, and the discharging device is a discharging screw conveyor for outputting compost products. Both the feeding screw conveyor and the discharging screw conveyor are of a shaftless screw structure.

[0014] Further, a temperature sensor and a gas concentration sensor electrically connected to the control device are also provided on the barrel of the fermentation drum for respectively detecting the temperature, oxygen content and methane gas concentration in the fermentation drum.

[0015] Further, a maintenance door and an induced draft fan communicating with the inside of the fermentation drum are also provided on the second end platform.

[0016] The technical solution of the present invention has the following advantages:

[0017] A. By fixing the first end platform and the second end platform at both ends of the fermentation drum, the present invention enables the feeding device and the discharging device not to rotate with the main body of the drum, realizes continuous feeding and discharging of the reactor, and provides an installation platform for the aeration system, thus solving the problem of greenhouse gas emissions caused by intermittent feeding and discharging of existing horizontal drum aerobic fermentation reactors. Through aerobic decomposition of microorganisms in the fermentation drum, the present invention converts organic substances that are highly harmful to the environment into nutrient substances that can be absorbed by plants, realizing the resource treatment of organic waste. It has the advantages of continuous feeding and discharging, an internal aeration system, a short fermentation cycle, and good fermentation and composting effects.

[0018] B. The present invention provides an aeration system installed on two end platforms and penetrating the cylinder body in the fermentation drum, which can transport fresh air more evenly and accurately to the bottom of the material pile, solving the problem of insufficient aeration that easily occurs in existing horizontal reactors relying only on the agitation of the agitating plates, and enabling the materials to be completely composted in a shorter cycle.

[0019] C. The present invention integrates the process steps of aeration, turning, dehumidification, etc. in traditional large-scale composting onto a single reactor device, making the fermentation process easier to control. The entire fermentation reactor has a high degree of automation, is easy to operate, occupies a small area, and is easy to realize the resource treatment of organic waste. It can be used for the resource utilization of livestock and poultry manure, tail vegetables, garden waste, etc., process and process organic waste into organic fertilizers, and can also be used as a soil conditioner to improve soil quality.

[0020] D. The present invention sets up a labyrinth seal at the joint position between the inner side surfaces at both ends of the fermentation drum and the first end platform and the second end platform. The labyrinth seal can self-adjust according to the change of working conditions. In the initial stage of startup or when the load suddenly increases, the fermentation drum may undergo a slight displacement. The labyrinth seal arranged between the barrel body of the fermentation drum and the side surfaces of the first end platform and the second end platform allows the sealing surface to adaptively adjust its position within a certain range through the hydrodynamic effect or the feedback of elastic elements, maintaining a stable fit at the seal without affecting the normal operation of the machine. At the same time, as a non-contact labyrinth seal, it avoids the friction problem existing in traditional packing seals, which means that even during long-term operation, it will not generate excessive heat or wear, extending the service life while reducing the maintenance cost. The labyrinth seal structure arranged at the opposite outer side surfaces of the first end platform and the second end platform is more convenient for replacement and maintenance.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] Such as Figure 1 And Figure 2As shown in the figure, the present invention provides a horizontal aerobic fermentation reactor, which includes a frame 1, a fermentation drum 2, a transmission system 3 and a control device (not shown in the figure) placed on the frame 1. The transmission system 3 is electrically connected to the control device. The transmission system 3 is used to drive the fermentation drum 2 to rotate. At both ends of the fermentation drum 2, there are also a first end platform 4 and a second end platform 5 which form a rotary labyrinth seal connection with it. The first end platform 4 and the second end platform 5 respectively form a sealing function with relative movement at both ends of the fermentation drum 2 to seal the materials at both ends of the fermentation drum 2, which can play the role of sealing materials and water during the fermentation process, and epoxy anti-corrosion paint is applied inside the fermentation drum 2; the first end platform 4 and the second end platform 5 are respectively fixed at both ends of the frame 1. There is a feed inlet on the upper part of the first end platform 4, and a feeding device 6 is installed at the feed inlet. The feeding end of the feeding device 6 is provided with a feed hopper. The materials are poured into the feed hopper through equipment such as lifting, and then the materials are transported into the interior of the fermentation drum 2 through the feeding device. At the same time, there is a discharge outlet at the lower part of the second end platform 5, and a discharging device 7 is installed at the discharge outlet. The discharging device 7 transports the fermented materials in the fermentation drum 2 out. There are also a plurality of push scraping plates 8 arranged at intervals on the inner side surface of the fermentation drum 2, which are used to turn and push the internal materials. The plurality of push scraping plates 8 are arranged in a spiral line, which can achieve the two functions of good stirring and pushing. At the same time, there is also an aeration system 9 arranged along the axial direction inside the fermentation drum 2. Both ends of the aeration system 9 are respectively fixedly connected to the first end platform 4 and the second end platform 5, which is used to fill fresh air into the materials to achieve better aerobic fermentation. As Figure 2 As shown in the figure, the barrel body of the fermentation drum 2 provided by the present invention is composed of a lining plate 24, a coating material layer 25 and a reinforcing rib plate 26. Here, the coating material layer adopts a polyurethane insulation layer with a thickness ≥ 50 mm. A series of push scraping plates 8 are arranged inside the fermentation drum 2. The plurality of push scraping plates 8 are arranged along its inner wall in a multi-head spiral line, such as a six-head spiral line distribution, and are fixed by bolts, which can be flexibly disassembled, replaced and adjusted in angle, and are used to transport materials and promote the contact between air and materials, so as to accelerate the aerobic fermentation process. In order to facilitate the real-time detection of the interior of the fermentation drum, the present invention can also set sensor mounting seats on the barrel body for the installation of sensors, such as installing a temperature sensor and a gas concentration sensor electrically connected to the control device, which are used to detect the temperature, oxygen content and the concentration of gases such as methane inside the fermentation drum 2 during the aerobic fermentation process in real time. The present invention uses a variety of sensors to detect various process technical indicators and greenhouse gas emission indicators during the aerobic fermentation process, and can realize the monitoring and feedback control of the process data during the composting process. The control device is used to complete operations such as device switching, parameter setting, man-machine interaction, data monitoring and data storage.

[0046] The present invention installs the feeding device and the discharging device on the first end platform 4 and the second end platform 5 respectively, which can realize automatic control of uninterrupted feeding and discharging, and adopts a detachable installation method.

[0047] As Figure 3 shown, the aeration system 9 includes an aeration blower (not shown in the figure) and a plurality of aeration pipes 91 arranged along the axial direction of the fermentation drum 2. The aeration pipes 91 are provided with solenoid valves 92 for controlling oxygen delivery and a plurality of aeration holes arranged along the pipe body. The aeration pipes 91 are connected by diagonal braces 94, which can effectively prevent the aeration pipes from deforming under the action of material resistance. Preferably, three aeration pipes are used. After the three aeration pipes are fixed by diagonal braces, a triangular cross-section structure is formed, and the aeration distribution is more uniform and the intensity is higher. Figure 3 One end of the aeration pipe 91 in Figure 3 is provided with a solenoid valve 92, and the other end is provided with a sealed pipe cap 93. The two ends of the aeration pipe 91 are respectively fixed to the first end platform 4 and the second end platform 5 in a penetrating manner. One end of the aeration pipe 91 is connected to the aeration blower, and the solenoid valve 92 and the aeration blower are respectively electrically connected to the control device. The aeration blower diffuses fresh air evenly into the material through the aeration pipe 91 by a plurality of aeration holes. In the present invention, the aeration pipe 91 is preferably arranged at the middle and lower positions of the fermentation drum 2, so that the material can obtain more uniform fresh air and accelerate the aerobic fermentation of organic waste.

[0048] Combined with Figure 1 and Figure 4 shown, the transmission system 3 includes a driving motor 31 fixed on the frame 1, a pair of limit edge wheels 32 and a pair of support wheels 33. A driving sprocket 34 is provided on the output shaft of the driving motor 31. A rim 21 of the edge wheel, a rim 22 of the support wheel and a transmission chain 23 corresponding to the limit edge wheel 32, the support wheel 33 and the driving sprocket 34 are respectively arranged on the outer wall of the fermentation drum 2. The limit edge wheel 32 and the support wheel 33 abut against the lower sides of the fermentation drum 2, playing a role in support, radial and axial limitation, and ensuring the stable operation of the fermentation drum 2. The driving sprocket 34 is in meshing transmission with the transmission chain 23. The driving motor 31 is installed on the frame 1 of the reactor by hexagon bolts. The driving sprocket 34 is installed on the output shaft of the driving motor 31. The transmission chain 23 is welded by multi-segment wing plates, which is convenient for replacement and installation. The driving motor 31 drives the fermentation drum 2 to rotate slowly through external meshing of the chain. The driving motor 31 can be adjusted in four directions to ensure the precise meshing of the chain and the sprocket. The sprocket and the chain are protected by a chain cover 35 to avoid rain erosion, corrosion and other situations.

[0049] The feeding device 6 therein is a feeding screw conveyor for feeding organic waste raw materials, bacterial agents and auxiliary materials into the fermentation drum 2, which is driven by an independent reduction motor. The discharging device 7 is a discharging screw conveyor for outputting compost products, which is driven by an independent reduction motor. Both the feeding screw conveyor and the discharging screw conveyor are of a shaftless screw structure.

[0050] As Figure 4As shown in the figure, the frame 1 mainly includes a base fixing plate 11, a long I-beam 14, and a short I-beam 16. A wheel seat fixing plate 12, a driving motor base 13, an end cover frame base 15, and an end cover frame vertical rib 17 are provided on the frame 1. A limiting edge wheel 32 and a support wheel 33 are installed on the wheel seat fixing plate 12, a driving motor 31 is installed on the driving motor base 13, and the end cover frame base 15 and the end cover frame vertical rib 17 are used to ensure the installation of the first end platform 4 and the second end platform 5.

[0051] As a further preferred embodiment of the present invention, the present invention is respectively provided with an annular stationary labyrinth ring 10 at the opposite end faces of the first end platform 4 and the second end platform 5. The stationary labyrinth ring 10 is filled with a movable sealing ring 20, and the movable sealing ring 20 forms a labyrinth seal with the barrel body of the fermentation drum 2. As Figure 5 Shown in the structural schematic diagram of the sealing part between the two end platforms and the fermentation drum 2. The labyrinth seal designs many tortuous small chambers between the stationary labyrinth ring 10 and the movable sealing ring 20 to form a series of throttling gaps and expansion cavities. These gaps and cavities act together. Due to the throttling effect and thermodynamic effect, the resistance to fluid leakage is increased, thereby reducing the flow velocity and kinetic energy, and finally achieving the sealing effect. The labyrinth seal solves the problems caused by the air permeation effect and has a better sealing effect. This sealing method can realize the independent rotation of the barrel body of the fermentation drum, and further realize the continuous feeding and discharging of the reactor. A maintenance door 30 is also provided on the second end platform 5 at the discharging end for experimental observation and cleaning and maintenance. An induced draft fan 40 is also provided above the maintenance door 30. The inlet of the induced draft fan 40 is connected to a pipeline passing through the second end platform 5. Part of the reactor device is installed on the frame 1 and fixed to the foundation by embedded iron or anchor bolts.

[0052] During operation, the organic waste raw materials are fed into the fermentation drum 2 through the feeding device 6; the fermentation drum 2 rotates at a low speed during the fermentation process, the aeration pipe 91 provides the oxygen necessary for composting, the pusher scraper 8 evenly disperses the materials and pushes them towards the discharging end, and the waste is discharged through the discharging device 7 after fermentation is completed. The waste gas generated during the fermentation process is extracted from the fermentation drum 2 by the induced draft fan 40.

[0053] The present invention adopts the above aerobic fermentation reactor to complete the functions of aeration, mixing, aerobic composting fermentation, and index monitoring in one device. The organic waste is fed into the fermentation drum of the reactor, and through the aerobic decomposition of microorganisms, the organic substances that are harmful to the environment are converted into nutrients that can be absorbed by plants, realizing the resource treatment of organic waste. It has the advantages of continuous feeding and discharging, built-in aeration device, short fermentation cycle, and good fermentation and ripening effect.

[0054] The aerobic fermentation reactor provided by the present invention is convenient to operate and has a high degree of automation. It is suitable for the harmless treatment of organic waste and the production of organic fertilizers, and has great market application prospects.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of this invention.
