Description

Technical Field

[0001] This invention relates to the field of feed processing fermentation technology, and in particular to an animal manure fermentation device for feed processing. Background Technology

[0002] Animal feces are not purely waste; they contain a large amount of nutrients that have not been digested and absorbed by the animals. Under suitable temperature, humidity, and ventilation conditions, the organic matter in the feces is decomposed and utilized by microorganisms. During fermentation, organic substances such as lactic acid, alcohols, and esters are produced, eliminating the original fecal odor and increasing palatability. It can be used as a protein feed ingredient and added to the daily diet of ruminants in a certain proportion.

[0003] Animal manure can be fermented into feed ingredients, which is essentially a microbial-driven "waste upgrading and recycling" process. It involves the decomposition and synthesis processes of microorganisms. This practice not only solves the environmental problem of livestock manure pollution but also achieves resource recycling, reduces feed costs, and is an important link in ecological agriculture and the circular economy.

[0004] Currently, drum-type equipment used for manure fermentation is a uniform, straight cylinder. As the drum rotates, the fermentation materials inside are turned and stirred by the internal lifting plates or fins. Furthermore, due to the tilt of the drum, the fermentation materials tend to move towards the lower end of the drum, meaning they can only move and assimilate with the fermentation environment within the drum. This results in significant differences in the fermentation state and assimilation between the materials and the drum environment at the two ends of the drum, which is detrimental to improving fermentation efficiency.

[0005] Therefore, it is necessary to develop an animal manure fermentation device for feed processing to solve the above problems. Summary of the Invention

[0006] This invention provides an animal manure fermentation device for feed processing, which solves the problem in the prior art where fermentation raw materials can only move and assimilate with the fermentation environment inside the drum. The fermentation state of the raw materials at both ends of the drum and the difference in assimilation between the raw materials and the drum environment are significant, which is detrimental to improving the fermentation efficiency of the raw materials.

[0007] This invention provides an animal manure fermentation device for feed processing, comprising: an inclined drum, with a sealing cover assembly, a support mechanism, a transmission component, and a circulating gas treatment assembly disposed outside the drum; along the direction of conveying the fermented material, the drum includes a collection section, a conveying section, and a fermentation stirring section, the inner diameter of the collection section being larger than that of the fermentation stirring section, a temporary storage area with a V-shaped cross-section being formed at the connection between the conveying section and the collection section, and a plurality of uniformly distributed lifting plates being fixedly connected to the inner walls of both the collection section and the fermentation stirring section of the drum; the sealing cover assembly includes a front sealing cover and a rear sealing cover respectively disposed at the beginning and end of the drum, the front sealing cover being provided with an airflow regulating component, and a water conveying section being disposed between the front sealing cover and the rear sealing cover inside the drum.

[0008] Furthermore, the support mechanism includes a base, the surface of which has the same inclination angle as the roller, and a support roller ring is fixedly connected to both the front and rear of the base surface. A plurality of evenly distributed rollers are arranged inside the support roller ring. The support mechanism is configured such that the rollers are all in contact with the outer surface of the roller and the roller can rotate.

[0009] Furthermore, the transmission component includes a gear ring sleeved on the outside of the drum, and a drive motor is fixedly connected to the surface of the base on the outside side of the drum. The output end of the drive motor is fixedly connected to a drive gear that meshes with the gear ring.

[0010] Furthermore, the airflow regulating assembly includes an air intake channel opened inside the front sealing cover, a plurality of evenly distributed perforated air distribution pipes are fixedly connected to the rear side of the front sealing cover inside the roller, and an air inlet pipe is fixedly connected to the front end of the front sealing cover. The air inlet pipe and the perforated air distribution pipes are connected through the air intake channel.

[0011] Furthermore, the water conveying section includes several evenly distributed water spray pipes disposed inside the drum. The water spray pipes are spirally distributed in opposite directions. One end of each water spray pipe is fixedly connected to the rear sealing cover, and the other end of each water spray pipe extends to the front side of the front sealing cover.

[0012] Furthermore, the length of the collecting section is less than that of the fermentation stirring section, and the angle between the inner wall of the conveying section and the inner wall of the collecting section is greater than the tilt angle of the drum. Several evenly distributed thermometers and oxygen detectors are provided on the outside of the drum. A feeding mechanism is provided on the front sealing cover, and a discharging mechanism is provided at the bottom of the rear sealing cover.

[0013] Furthermore, the circulating air treatment assembly includes a condenser, an air regulating valve, a fan, and a heater disposed outside the drum. An air outlet pipe is fixedly connected to the top of the rear sealing cover. The air outlet pipe and the condenser are connected by a pipeline, and the heater and the air inlet pipe are connected by a pipeline.

[0014] Furthermore, the inclination angle of the roller is 3~5°, the roller has a heat preservation function, the inner wall of the conveying part is smooth, and its inner diameter gradually decreases along the direction from the collecting part to the fermentation stirring part. The inner wall of the conveying part is inclined upwards along the conveying direction of the fermented material compared with the mounting plane of the roller.

[0015] Furthermore, the condenser, air regulating valve, fan and heater are connected in sequence through pipes, and the air inlet pipe and air outlet pipe are both connected to the inside of the drum.

[0016] Furthermore, a number of evenly distributed guide plates are fixedly connected to the rear side of the front sealing cover to cooperate with the perforated air pipe. The guide plates are configured to guide the airflow ejected from the perforated air pipe toward the rear sealing cover.

[0017] The present invention provides an animal manure fermentation device for feed processing, which has the following technical effects or advantages: 1. The drum, constructed using a variable-diameter pipe, is divided into a collection section, a conveying section, and a fermentation mixing section. The collection section prevents blockages when raw materials enter the drum. The fermentation mixing section reduces the rotation required for turning the raw materials during fermentation, shrinks the fermentation space, and facilitates more synchronized temperature and humidity during fermentation. The temporary storage area formed between the conveying and collection sections temporarily stores the fermentation raw materials transported from the collection section to the fermentation mixing section. Under the rotation of the drum, the raw materials are pre-mixed and pre-fermented, increasing the synchronization rate between the fermentation raw materials and the internal temperature and humidity environment of the drum, which helps to accelerate the fermentation rate of the raw materials in the fermentation mixing section.

[0018] 2. The circulating gas treatment assembly separates the gas used for fermentation inside the drum into gas and liquid, reducing the absorption of heat by other media during the heating process of the required gas, thus reducing the energy consumption generated by heating. The gas discharged from inside the drum itself carries a certain amount of heat and is recycled, which can also reduce energy consumption. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] As mentioned earlier, in existing drum fermentation equipment, the fermentation raw materials can only move and assimilate with the fermentation environment inside the drum. The fermentation state of the raw materials at both ends of the drum and the assimilation between the raw materials and the drum environment are quite different, which is not conducive to improving the fermentation efficiency of the raw materials.

[0024] To address this, the present invention provides an animal manure fermentation device for feed processing, which is divided into a collection section 2, a conveying section 3, and a fermentation and stirring section 4 by a drum 1 made of a variable-diameter pipe. The collection section 2 has a larger inner diameter to avoid blockage of the feed when the raw materials enter the drum 1, while the fermentation and stirring section 4 has a smaller inner diameter to reduce the rotation required for turning the raw materials during fermentation, reduce the fermentation space, and facilitate the synchronization of temperature and humidity during fermentation. A temporary storage area 5 is formed between the conveying section 3 and the collection section 2. The temporary storage area 5 temporarily stores the fermentation raw materials transported from the collection section 2 to the fermentation and stirring section 4. Under the rotation of the drum 1, the fermentation raw materials are pre-mixed and pre-fermented, increasing the synchronization rate of the fermentation raw materials and the internal environment of the drum 1, which is beneficial to accelerating the fermentation rate of the raw materials in the fermentation and stirring section 4. Several guide plates 703 are fixedly connected to the rear side of the front sealing cover 601. The guide plates 703 guide the airflow ejected from the perforated air distribution pipe 702 to the rear end of the drum 1, so that the airflow entering the drum 1 flows more evenly backward, reduces the interception of heat in the airflow during the fermentation process of the fermentation raw materials, increases the even distribution of heat in the airflow throughout the drum 1, and accelerates the unification of the fermentation environment in the drum 1. The circulating gas treatment assembly 11 performs gas-liquid separation on the gas used for fermentation inside the drum 1, reducing the absorption of heat by other media during the heating process of the required gas, thus reducing the energy consumption generated by heating. The gas discharged from inside the drum 1 itself carries a certain amount of heat and is recycled for use, which can also reduce energy consumption.

[0025] The following is combined Figures 1-5 This invention is described in detail.

[0026] like Figures 1-5 As shown, the present invention provides a fermentation device, particularly an animal manure fermentation device for feed processing. In this embodiment, the fermentation device mainly includes a roller 1 inclined at 3-5°. The roller 1 is a variable-diameter roller, with a larger opening for feeding and a smaller opening for stirring and fermentation. The two sections are connected by a continuous conical tube, as shown below. Figure 3As shown, the inlet end is the beginning end, and the outlet end is the end end. The length of the collecting section 2 is less than the length of the fermentation mixing section 4, and the angle between the inner wall of the conveying section 3 and the inner wall of the collecting section 2 is greater than the angle between the axis of the drum 1 and the horizontal plane. The conveying section 3 is inclined upward relative to the horizontal plane. The beginning section is the collecting section 2, and the end section is the fermentation mixing section 4. The part connecting the two is the conveying section 3. The length of the fermentation mixing section 4 is greater than that of the collecting section 2. This larger opening in the collecting section 2 makes it less likely to cause blockage at the beginning end of the drum 1 when manure and other raw materials are fed into the drum 1. As the drum 1 rotates, tilts, and fermentation raw materials are continuously fed in, the raw materials entering the collecting section 2 are conveyed to the fermentation mixing section 4. In the fermentation mixing section 4, in order to increase the mixing efficiency, as well as the collection, conveying, and temperature and humidity control of the fermentation raw materials, the inner diameter of the fermentation mixing section 4 is smaller, which increases the turning efficiency of the fermentation materials in the fermentation mixing section 4 due to the rotation of the drum 1.

[0027] The inner wall of the conveying section 3, which connects the collecting section 2 and the fermentation mixing section 4, is smooth and does not have lifting plates 12. The inner diameter of the conveying section 3 gradually decreases along the direction from the collecting section 2 to the fermentation mixing section 4, forming a concave, V-shaped temporary storage area 5 at the connection between the conveying section 2 and the collecting section 2. This allows the raw materials for fermentation to briefly reside inside the collecting section 2, where temperature and humidity are controlled and adjusted, and the materials are mixed and stirred for a certain period for pretreatment. Then, through the subsequent extrusion and pushing of the feed, the fermented material is continuously conveyed into the fermentation mixing section 4.

[0028] like Figure 3 As shown, inside the drum 1, several evenly distributed lifting plates 12 are fixedly connected to the inner walls of the material collection section 2 and the fermentation stirring section 4. The lifting plates 12 are used to lift and agitate the fermentation raw materials that have settled at the bottom of the drum 1 by gravity as the drum 1 rotates. The drum 1 is tilted at 3-5°, which ensures both the backward conveying of the fermentation raw materials inside the drum and their distribution within the drum 1, preventing rapid accumulation towards the discharge direction and ensuring sufficient fermentation time. A support mechanism 9 is installed outside the drum 1 to support its tilted position while also ensuring its rolling motion. A transmission component 10 and a circulating gas treatment assembly 11 are also installed outside the drum 1. The transmission component 10 provides driving force for the drum 1 to roll, while the circulating gas treatment assembly 11 dries the heat generated during fermentation inside the drum 1 and any unused heat-laden gas, then introduces it back into the drum 1 at the required temperature, reducing the energy consumed in heating the gas during fermentation and achieving energy savings.

[0029] like Figures 1-3As shown, the support mechanism 9 may include two bases 901, the upper surfaces of which are inclined at 3-5° along the direction of the roller 1. A support ring 902 is fixedly installed on the surface of each base 1. The support ring 902 and the roller 1 are concentrically arranged. Several evenly distributed rollers 903 are arranged on the inner edge of the support ring 902. The surface of the rollers 903 is in contact with the outer surface of the roller 1, and the rotation axis of the rollers 903 is parallel to the axial direction of the roller 1. The roller 1 is inside the support ring 902 and can rotate under the support of the rollers 903.

[0030] To drive the rotation of the drum 1, a transmission component 10 is provided on the outside of the drum 1. The transmission component 10 may include a gear ring 1001, a drive motor 1002, and a drive gear 1003. A gear ring 1001 is fitted on the outer surface of the drum 1, with the teeth of the gear ring 1001 facing outwards. The inner wall of the gear ring 1001 is fixedly connected to the outer wall of the drum 1. A drive motor 1002 is fixedly connected to the surface of one of the bases 901. A drive gear 1003 is fixedly connected to the output end of the drive motor 1002. The drive gear 1003 meshes with the gear ring 1001.

[0031] To adjust the humidity inside the drum 1 by supplying water, a water supply section 8 is provided inside the drum 1. Simultaneously, to ensure the drum 1 is sealed, insulated, and moisturized, a sealing cover assembly 6 is provided outside the drum 1. The sealing cover assembly 6 may include a front sealing cover 601 and a rear sealing cover 602. The front sealing cover 6 is fitted onto the beginning of the drum 1, and the rear sealing cover 602 is fitted onto the end of the fermentation and stirring section 4 of the drum 1. The drum 1 rotates between the two sealing covers, but the two sealing covers do not rotate with the drum 1, and there is a sealed connection between the sealing covers and the drum 1. The drum 1 can rotate between the two sealing covers. The water supply section 8 may include several water spray pipes 801 evenly distributed inside the drum 1, such as... Figure 3 As shown, several water spray pipes 801 are spirally distributed in opposite directions. Along the direction of the pipes, several water spray holes are opened on the outer wall of the water spray pipes 801. The water spray holes on the outer wall of the multiple water spray pipes 801 can be distributed at different positions along the axial direction of the roller 1, increasing the number of water spray points of the water conveying part 8 inside the roller 1 and accelerating the synchronization of humidity inside the roller 1.

[0032] To facilitate the introduction of oxygen into the drum 1, an airflow regulating component 7 is provided on the front sealing cover 601. The airflow regulating component 7 may include an air intake channel 701 formed inside the front sealing cover 601. Several evenly distributed perforated air distribution pipes 702 are fixedly connected to the interior of the front sealing cover 601 near the drum 1. An air inlet pipe 13 is fixedly connected to the exterior of the front sealing cover 601 away from the drum 1, and the air inlet pipe 13 and the perforated air distribution pipes 702 are connected through the interior of the air intake channel 701. Several evenly distributed guide plates 703 are fixedly connected to the front sealing cover 601 near the drum 1, inside the drum 1. The guide plates 703 guide the divergent gas injected into the drum 1 by the perforated air distribution pipes 702 backward, increasing the length of the airflow delivered into the drum 1 towards the rear sealing cover 602 and increasing the uniformity of airflow delivery inside the drum 1. Furthermore, as the heat in the airflow moves backward, the absorption and interception of heat in the airflow by the fermentation raw materials are reduced, which helps to increase the uniform distribution of heat inside the entire drum 1. One end of the water supply pipe 801 is fixedly connected to the rear sealing cover 602, and the other end passes through the front sealing cover 601 outward in a goose-shaped pattern. The water supply pipe 801 and the air intake channel 701 are completely isolated and do not conduct heat.

[0033] A feeding mechanism 16 is provided on the outer side of the front sealing cover 601 away from the drum 1. The feeding pipe of the feeding mechanism 16 extends into the interior of the drum 1 and passes through the interior of the air intake chamber 701. The feeding pipe of the feeding mechanism 16 and the air intake chamber 701 are completely isolated, and the temperature of the airflow transported inside the air intake chamber 701 will not be transmitted to the interior of the feeding mechanism 16. The feeding mechanism 16 may also include a screw-type mixing mechanism provided before the feeding pipe to pre-stir the fermentation raw materials fed into the drum 1, increase the efficiency of uniform mixing of the fermentation raw materials inside the drum 1, increase fermentation uniformity, and reduce the fermentation time.

[0034] An exhaust pipe 18 is fixedly connected to the top of the rear sealing cover 602. A circulating air treatment assembly 11 is installed outside the drum 1 between the inlet pipe 13 and the exhaust pipe 18. The circulating air treatment assembly 11 may include a condenser 1101, an air regulating valve 1102, a fan 1103, and a heater 1104. The condenser 1101 is used to separate the gas containing moisture discharged from inside the drum 1, keeping the circulating gas dry after leaving the drum 1. The air regulating valve 1102 is used to control the airflow rate of the gas recirculated into the drum 1 after being discharged from the drum 1. The fan 1103 is used to regulate the airflow speed of the circulating gas delivered to the drum 1. The heater 1104 is used to regulate the temperature of the circulating gas entering the drum 1. The condenser 1101 removes moisture, reducing the absorption of heat by other media during the heating process and reducing heating energy consumption. The gas discharged from inside the drum 1 carries heat and is recycled, which also reduces energy consumption. Condenser 1101, air regulating valve 1102, fan 1103 and heater 1104 are connected in sequence by pipes. Air outlet pipe 18 is connected to condenser 1101 by pipe, and heater 1104 is connected to air inlet pipe 13 by pipe.

[0035] Several evenly distributed thermometers 14 and oxygen detectors 15 are installed on the outside of the drum 1. In this embodiment, three thermometers 14 and two oxygen detectors 15 are used as an example. The three thermometers 14 are distributed at three positions on the drum 1, and the probes of the thermometers 14 extend into the inside of the drum 1 to measure the temperature at the three positions inside the drum 1, which are recorded as T1, T2, and T3. The oxygen detectors 15 are distributed at the front and rear positions of the drum 1, and the probes of the oxygen detectors 15 also extend into the inside of the drum 1 to detect the oxygen content inside the drum 1. This allows for the monitoring of the average temperature and average oxygen content inside the drum 1, facilitating timely adjustment of the temperature and oxygen content inside the drum 1.

[0036] In practical application, using bamboo rat droppings as an example, mix bamboo rat droppings and compound fertilizer (N-P2O5-K2O:14-16-15) at a ratio of 100:7. Before fermentation, the mixture needs to be crushed to 5mm, with a moisture content of 55%. Fill the drum with packing material to 2 / 3 of its volume, and add 1% Bacillus subtilis (dry weight of the droppings). Figure 5 The raw materials are fed into the feeding mechanism 16 at point A, and after initial mixing, they enter the collection section 2 inside the drum 1. Inside the collection section 2, the raw materials are mixed and collected, and continuously agitated by the lifting plates 12. Simultaneously, heated oxygen is introduced into the drum 1 through the airflow regulating component 7 and the circulating air treatment assembly 11. Figure 5At point C, water is added to the inside of drum 1 via water spray pipe 801 to adjust the humidity inside drum 1. The overall temperature, humidity, oxygen, and water supply are controlled by a PLC control system. The fermentation raw materials are pre-mixed and pre-fermented in the collection section 2. As drum 1 rotates and tilts, some of the fermentation raw materials remain in the temporary storage area 5, where they are collected, mixed, and fermented again. The temperature and humidity of the fermentation raw materials are further assimilated with those inside drum 1, increasing the consistency between the fermentation raw materials and the temperature and humidity inside drum 1. Subsequently, fermentation raw materials are continuously fed into the collection section 2. The fermentation raw materials that have been further mixed and fermented in the temporary storage area 5 are pushed and squeezed into the fermentation mixing section 4 of drum 1 for final mixing and final fermentation. Finally, the fermentation raw materials are discharged from the collection section 2. Figure 5 The waste is discharged at point B. During the fermentation process inside drum 1, water is added 1-2 times daily. During both the heating and cooling periods, the interior of drum 1 needs to be ventilated twice and the stack turned twice via the airflow regulating component 7 and the circulating air treatment assembly 11. If the temperature inside drum 1 exceeds 70℃, the frequency of turning and ventilation needs to be increased. The cellulose in bamboo rat feces is fermented to produce feed ingredients.

[0037] In summary, the animal manure fermentation equipment for feed processing described in this invention has the following advantages: 1. The drum 1 is made of a variable-diameter pipe and can be divided into a collection section 2, a conveying section 3, and a fermentation and stirring section 4. The collection section 2 has a larger inner diameter to avoid blockage when raw materials enter the drum 1. The fermentation and stirring section 4 has a smaller inner diameter to reduce the rotation required for turning the raw materials during fermentation, reduce the fermentation space, and facilitate the synchronization of temperature and humidity during fermentation. A temporary storage area 5 is formed between the conveying section 3 and the collection section 2. The temporary storage area 5 temporarily stores the fermentation raw materials transported from the collection section 2 to the fermentation and stirring section 4. Under the rotation of the drum 1, the fermentation raw materials are pre-mixed and pre-fermented, increasing the synchronization rate of the fermentation raw materials and the internal environment of the drum 1, which is conducive to accelerating the fermentation rate of the raw materials in the fermentation and stirring section 4.

[0038] Second, several guide plates 703 are fixedly connected to the rear side of the front sealing cover 601. The guide plates 703 guide the airflow ejected from the perforated air distribution pipe 702 to the rear end of the drum 1, so that the airflow entering the drum 1 flows more evenly backward, reduces the interception of heat in the airflow during the fermentation of the raw materials, increases the even distribution of heat in the airflow throughout the drum 1, and accelerates the unification of the fermentation environment in the drum 1.

[0039] Third, the gas used for fermentation inside the drum 1 is separated into gas and liquid by the circulating gas treatment assembly 11, which reduces the absorption of heat by other media during the heating process of the required gas, thus reducing the energy consumption generated by heating. The gas discharged from inside the drum 1 itself has a certain amount of heat, and it is recycled for use, which can also reduce energy consumption.

[0040] The PLC control system used to control the motor and the thermometer and oxygen detector used for measurement in the equipment are existing technologies, common knowledge in the field, and are not part of the improvement technology in this case, so they will not be described in detail here.
