Description

Technical Field

[0001] The present invention relates to the technical field of fermentation devices, and particularly to a continuous double-chamber fermentation device. Background Technique

[0002] At present, for reactor-type fermentation tanks at home and abroad, since the reactor generally uses electric heating to preheat and raise the temperature of the stacked materials, a high-power blower is used to provide oxygen for the stack, and a stirrer is provided to turn the stack up and down, so there is a high energy consumption loss. Due to the excessive investment cost and the relatively low price of organic fertilizers, this has severely restricted the willingness to process and produce low-value organic fertilizers relying on raw materials such as straw and manure, resulting in the fact that reactors with relatively high fermentation efficiency generally become decorations and do not play their due roles. In addition, the mainstream reactors are only designed with one fermentation chamber. When operating in the north, especially in winter, the temperature of the new materials is generally low, and even in a frozen state. After being added to the fermentation chamber, the low-temperature materials will immediately inhibit the fermentation reaction in the high-temperature fermentation state, resulting in the termination of the fermentation process, delaying the reaction cycle in a disguised form, and seriously affecting the fermentation efficiency. By using a continuous fermentation device, since the raw materials can be initially heated and fermented in the pre-fermentation chamber, the situation of terminating the fermentation process due to low temperature will not occur when added to the main fermentation chamber, realizing continuous fermentation, thereby promoting the improvement of fermentation efficiency. Therefore, a double-chamber continuous fermentation device is designed to avoid the influence of subsequent feeding on the materials being fermented. Summary of the Invention

[0003] The purpose of the present invention is to provide a continuous double-chamber fermentation device to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A continuous double-chamber fermentation device, including a pre-fermentation chamber and a fermentation chamber. The pre-fermentation chamber is connected to the fermentation chamber through a feeding device. The fermentation chamber is of a horizontal structure and includes a drum, a feeding box, a discharging box, a friction ring, and a driving roller. The feeding box and the discharging box are respectively arranged at both ends of the drum. The friction ring is arranged on the drum. The driving roller is arranged at the bottom of the friction ring. The driving roller is connected to a driving motor. An inner cylinder is arranged inside the drum, and the diameter of the feeding end of the inner cylinder is larger than that of the discharging end.

[0005] Preferably, the feeding device is a screw conveyor, and the feeding end of the screw conveyor is connected to the pre-fermentation chamber through a hose.

[0006] Preferably, the driving roller and the driving motor are both installed on a drum support frame.

[0007] Preferably, a plurality of reagent addition boxes are arranged on the pre-fermentation chamber, and a weighing sensor for weighing is arranged on the reagent addition box, which can be used to add additive components such as different bacterial agents and organic carbon.

[0008] Preferably, a stirring rod, a rotating sleeve, a fixed partition, a movable partition, and a rotating sleeve driving device are arranged inside the pre-fermentation bin. The rotating sleeve is sleeved on the stirring rod. The fixed partition is connected to the stirring rod. The movable partition is connected to the rotating sleeve. The rotating sleeve driving device is arranged on the top of the rotating sleeve and is used to drive the rotation of the rotating sleeve to stop.

[0009] Preferably, the rotating sleeve driving device includes an orbital disc, a movable locking tongue mechanism, a gear ring, a rotating limit plate, a gear motor, and a gear. The movable locking tongue mechanism is movably arranged on the orbital disc. The gear ring is arranged on the lower side of the orbital disc. The rotating limit plate is arranged on the orbital disc and can rotate around the orbital disc. A gear motor and a gear are arranged on the rotating limit plate. The gear motor is drivingly connected to the gear. The gear meshes with the gear ring. A push rod is arranged on the stirring rod on one side of the rotating sleeve driving device. The push rod acts on the movable locking tongue mechanism to drive the rotating sleeve to rotate.

[0010] Preferably, the movable locking tongue mechanism includes a locking tongue body, a T-shaped rod, and a spring. The locking tongue body is arranged at one end of the T-shaped rod. The spring is sleeved on the T-shaped rod and is used to push the movable locking tongue mechanism to move downward.

[0011] Preferably, a discharge baffle is arranged at one end of the drum. A discharge opening is formed in the discharge baffle. A discharge stirring mechanism is rotatably arranged in the discharge opening.

[0012] Preferably, the discharge stirring mechanism includes a door panel, a door panel fixing rod, a door panel connecting rod, a moving rod, a push-pull rod, a rotating rod, and a rotating motor. The output end of the rotating motor is connected to the rotating rod. The door panel fixing rod is fixed on one side of the door panel. The door panel connecting rod is rotatably connected to the door panel fixing rod and the moving rod. The push-pull rod is fixedly arranged on the moving rod. One end of the push-pull rod is arranged in the kidney-shaped hole of the rotating rod. The thickness of the door panel is greater than the thickness of the discharge baffle. When the door panel is closed, the door panel protrudes inward. When the drum rotates, the inwardly protruding part of the door panel picks up the material, avoiding excessive extrusion and accumulation of the internal material at the discharge end.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The pre-fermentation bin is separated by the movable partition and the fixed partition. The later added material is in the upper part of the pre-fermentation bin. The temperature generated by the pre-fermentation of the material already added in the lower part of the pre-fermentation bin will heat the later added material in the upper part, avoiding the influence of directly adding materials with low temperature on the existing fermentation process and ensuring the fermentation efficiency;

[0015] The movable partition and the fixed partition are driven to rotate by the stirring rod and are matched with the rotating sleeve driving device, which can control the gap between the movable partition and the fixed partition, facilitating the falling of materials and separating the materials. The design is ingenious and very practical;

[0016] The horizontal - structure fermentation tank is adopted, and the fermentation tank is driven to rotate by a driving wheel with a friction structure, which is convenient to use and has low cost. Compared with the stirring structure of the vertical fermentation tank, it is more energy - saving;

[0017] The door panel is designed with a conical - convex structure and has two functions. After the door panel is closed, the convex part inside the door panel lifts the material, avoiding excessive extrusion and accumulation of the internal material at the discharging end, and having the function of loosening the material at the end; after the door panel is opened, the material can be discharged from the discharging opening.

[0018] The stirring device and the air - blowing device are cancelled inside the main fermentation bin, and the material - scraping plate is used for turning the pile. The up - and - down stirring of the materials piled inside the tank body is carried out by using gravity, so as to achieve the purpose of significantly reducing the mechanical energy consumption.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0032] Please refer to Figure 1 , the present invention provides a technical solution: a continuous double-chamber fermentation device, including a pre-fermentation chamber 1 and a fermentation chamber 5. A reagent addition tank 2 is provided on the pre-fermentation chamber 1, and a weighing sensor for weighing is provided on the reagent addition tank 2. Fermentation reagents are stored in the reagent addition tank 2 and added according to requirements. The bottom of the pre-fermentation chamber 1 is connected to a hose 3, and the hose 3 is connected to the fermentation chamber 5 through a screw feeder

[0033] As Figure 2 and Figure 3 shown, the fermentation chamber 5 is a horizontal structure, including a drum 51, a feed box 52, a discharge box 53, a friction ring 54, and a driving roller 56. The feed box 52 and the discharge box 53 are respectively arranged at both ends of the drum 51. The friction ring 54 is arranged on the drum 51. The driving roller 56 is arranged at the bottom of the friction ring 54. The driving roller 56 is connected to a driving motor 57. The driving roller 56 and the driving motor 57 are both installed on the drum support frame 55. The driving motor 57 drives the driving roller 56 to rotate. Two driving rollers 56 support a friction ring 54. The rotation of the driving roller 56 drives the friction ring 54 to rotate, thereby driving the drum 51 to rotate, and the internal materials can be stirred. An inner cylinder 58 is arranged inside the drum 51, and the diameter of the feeding end of the inner cylinder 58 is larger than that of the discharging end. When the materials are full, a non-Newtonian fluid pressure difference is formed to promote the materials to move to the right side, facilitating discharging

[0034] The inner wall of the inner cylinder 58 is designed with a material scooping plate for turning and stirring. Heat insulation and heat preservation materials can be filled between the inner cylinder 58 and the drum 51 to improve the heat insulation effect

[0035] As Figures 6 - 9As shown in the figure, a stirring rod 11, a rotating sleeve 12, a fixed partition 13, a movable partition 14, and a rotating sleeve driving device 15 are arranged inside the pre-fermentation bin 1. The rotating sleeve 12 is sleeved on the stirring rod 11. The fixed partition 13 is connected to the stirring rod 11. The movable partition 14 is connected to the rotating sleeve 12. The fixed partition 13 and the movable partition 14 divide the inside of the pre-fermentation bin 1 into upper and lower parts. Stirring cross bars are arranged in both the upper and lower parts. The lower part stirring cross bar is fixedly arranged at the lower part of the stirring rod 11. The upper part stirring cross bar is fixedly arranged on the inner wall of the pre-fermentation bin 1. The rotating sleeve driving device 15 is arranged at the top of the rotating sleeve 12 and is used to drive the rotation of the rotating sleeve 12 to stop.

[0036] The rotating sleeve driving device 15 includes a track plate 151, a movable lock tongue mechanism 152, a gear ring 153, a rotation limit plate 154, a gear motor 155, and a gear 156. The movable lock tongue mechanism 152 is movably arranged on the track plate 151. The movable lock tongue mechanism 152 includes a lock tongue body, a T-shaped rod and a spring. The lock tongue body is arranged at one end of the T-shaped rod. The spring is sleeved on the T-shaped rod and is used to push the movable lock tongue mechanism 152 to move downward. The upper end of the spring acts on the track plate 151 to support the spring. The gear ring 153 is arranged on the lower side of the track plate 151. The rotation limit plate 154 is provided. The positioning plate 154 is a G-type structure, one end of which is clamped on the inner side of the track disk 151 and the other end is clamped on the lower side of the track disk 151, so that the rotating limiting plate 154 rotates around the track disk 151 without falling off easily; a gear motor 155 is arranged on the outer side of the rotating limiting plate 154, and the gear motor 155 is connected to the transmission box on the lower side of the track disk 151, and the output end of the transmission box is connected to a gear 156, which is meshed with the ring gear 153. A push rod 111 is arranged on the stirring rod 11 on one side of the rotating sleeve driving device 15, and the push rod 111 acts on the movable locking tongue mechanism 152 to drive the rotating sleeve 12 to rotate. The stirring rod 11 drives the push rod 111 to rotate. When the push rod 111 rotates to the position of the movable locking tongue mechanism 152 where the rotation limit plate 154 is located, since the upper end of the movable locking tongue mechanism 152 is blocked by the rotation limit plate 154 and cannot move upward, the push rod 111 will push the movable locking tongue mechanism 152, thereby rotating the entire rotating sleeve 12, and the movable partition 14 on the rotating sleeve 12 rotates accordingly. When the movable partition 14 is completely staggered from the fixed partition 13, the pre-fermentation bin 1 will be separated. At this time, material can be added. The post-addition material is at the upper part of the pre-fermentation bin 1, and the temperature generated by the pre-fermentation of the pre-fermentation bin 1 that has been added at the lower part of the pre-fermentation bin 1 The temperature will heat the upper rear material. When the rear material reaches the preset temperature, the gear motor 155 drives the rotating limit plate 154 to the next position, and the stirring rod 11 continues to rotate, driving the fixed partition 13 to rotate. At this time, the movable partition 14 is not subjected to thrust and remains stationary. When the push rod 111 rotates to the movable locking tongue mechanism 152 at the next position, the movable locking tongue mechanism 152 can be pushed to make the movable partition 14 rotate with it. At this time, the movable partition 14 partially overlaps with the fixed partition 13, and the rear material can fall from the gap to the lower part of the pre-fermentation bin 1; the specific size of the gap is determined by the position of the rotating limit plate 154.

[0037] like Figure 4 and Figure 5As shown, a discharge baffle 59 is provided at one end of the roller 51. A discharge opening 510 is formed in the discharge baffle 59, and a discharge stirring mechanism 6 is rotatably arranged in the discharge opening 510. The discharge stirring mechanism 6 includes a door panel 61, a door panel fixing rod 62, a door panel connecting rod 63, a moving rod 64, a push-pull rod 65, a rotating rod 66 and a rotating motor 67. The output end of the rotating motor 67 is connected to the rotating rod 66. The door panel fixing rod 62 is fixed on one side of the door panel 61. The door panel connecting rod 63 is rotatably connected to the door panel fixing rod 62 and the moving rod 64. The push-pull rod 65 is fixedly arranged on the moving rod 64. One end of the push-pull rod 65 is arranged in the waist-shaped hole of the rotating rod 66. When the rotating motor 67 rotates, the door panel 61 is driven to rotate through the rotating rod 66, the push-pull rod 65, the moving rod 64 and the door panel connecting rod 63, so as to realize the opening and closing of the door panel 61. The thickness of the door panel 61 is greater than that of the discharge baffle 59, and the whole is conical, and the outer side surface is an arc surface. When the door panel 61 is closed, the door panel 61 protrudes inward. When the roller 51 rotates, the convex part inside the door panel 61 lifts the material, avoiding excessive extrusion and accumulation of the internal material at the discharge end, and having the function of loosening the end material. Compared with the piled-up material, the oxygen is more sufficient, which is convenient for fermentation. After the door panel 61 is opened, the material can pass through the discharge opening 510 and be discharged by the discharge box 53.
