Description

Technical Field

[0001] The invention relates to the technical field of fermentation devices, in particular to a continuous double-bin fermentation device. Background Art

[0002] At present, reactor-type fermentation tanks at home and abroad have high energy consumption because the reactor generally uses electric heating to preheat the pile, a high-power blower provides oxygen to the pile, and a stirrer is provided to turn the pile up and down. Due to the high investment cost and the low price of organic fertilizer, this seriously limits the willingness to rely on raw materials such as straw and manure to process and produce low-value-added organic fertilizers, resulting in the reactor with higher fermentation efficiency generally becoming a decoration and not playing its due role. In addition, the mainstream reactor is designed with only one fermentation bin. When operating in the north, especially in winter, the temperature of the new material is generally low, or even in a frozen state. After adding it to the fermentation bin, the low-temperature material will immediately inhibit the fermentation reaction in the high-temperature fermentation state, resulting in the termination of the fermentation process, which in turn delays the reaction cycle and seriously affects the fermentation efficiency. With a continuous fermentation device, since the raw materials can be initially heated and fermented in the pre-fermentation bin, the fermentation process will not be terminated due to low temperature when added to the main fermentation bin, and continuous fermentation is achieved, thereby promoting the improvement of fermentation efficiency. Therefore, a double-bin continuous fermentation device is designed to prevent subsequent feeding from affecting the fermenting materials. Summary of the invention

[0018] See also Figure 1 The present invention provides a technical solution: a continuous double-bin fermentation device, comprising a pre-fermentation bin 1 and a fermentation bin 5, a drug adding box 2 is arranged on the pre-fermentation bin 1, and a weighing sensor for weighing is arranged on the drug adding box 2, the drug adding box 2 stores the fermentation drug, and the drug is added according to demand, the bottom of the pre-fermentation bin 1 is connected to a hose 3, and the hose 3 is connected to the fermentation bin 5 through an auger feeder.

[0019] like Figure 2 and Figure 3 As shown, the fermentation bin 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 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, which can stir the internal materials. 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 the diameter of the discharging end. When the material is filled, a non-bullshield fluid pressure difference is formed to promote the material to move to the right, which is convenient for discharging. The inner wall of the inner cylinder 58 is designed with a material lifting plate for turning and stirring the pile. The space between the inner cylinder 58 and the roller 51 can be filled with heat insulation material to improve the heat insulation effect.

[0020] like Figure 6-Figure 9 As shown, 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, and the movable partition 14 is connected to the rotating sleeve 12. The fixed partition 13 and the movable partition 14 divide the pre-fermentation bin 1 into two parts, an upper part and an lower part. A stirring cross bar is arranged in both the upper and lower parts. The stirring cross bar of the lower part is fixedly arranged at the lower part of the stirring rod 11, and the stirring cross bar of the upper part is fixedly arranged on the inner wall of the pre-fermentation bin 1. The rotating sleeve driving device 15 is arranged on the top of the rotating sleeve 12 for driving the rotating sleeve 12 to stop.

[0021] 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 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 limit 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 limit 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, and the gear 156 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 up, 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.

The thickness of the door panel 61 is greater than the thickness of the discharge baffle 59. The overall shape is conical, and the outer side surface is an arc-shaped surface. When the door panel 61 is closed, the door panel 61 protrudes inward, and the drum 51 rotates. The convex part of the door panel 61 brings up the material to avoid excessive extrusion and accumulation of the internal material at the discharge end. It has the function of loosening the end material, and compared with the accumulated 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 from the discharge box 53.
