Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer processing technology, specifically to a fermentation device for diatom-based organic fertilizer. Background Technology

[0002] In the modern production process of diatom-based organic fertilizer, full fermentation is required. Diatoms can reproduce rapidly at temperatures above 5°C, forming a dominant population that inhibits the outbreak of harmful algae such as blue-green algae and moss. At the same time, they produce a porous structure, which facilitates the deposition of organic matter and increases the fertility per unit density. At present, the fermentation process of diatom-based organic fertilizer mainly relies on tank fermentation equipment, which not only occupies a small area but also has high fermentation efficiency.

[0003] However, current tank fermentation equipment is mainly a horizontal tank structure, and in order to avoid the escape of odor, it is usually only equipped with one inlet and one outlet. However, the fermentation process requires the material to have full contact with air. Current fermentation equipment mainly relies on natural air intake through the inlet or outlet, and the air intake is small, which prolongs the fermentation time and limits the fermentation efficiency. In view of this, in-depth research was conducted on the above problems, which led to this case. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides an implementation scheme: In the fermentation process of modern diatom-based organic fertilizer, fermentation equipment is required for fermentation treatment. During the fermentation process, the fermentation material needs to be in full contact with the air. At present, most fermentation equipment is equipped with stirring equipment, which can stir the material and make the material in full contact with the air. However, since the fermentation equipment often only has an inlet and an outlet, it makes full contact with the air by natural air intake. As a result, the air intake is small, which slows down the fermentation rate.

[0018] To address the aforementioned issues, this application discloses a fermentation device for diatom-based organic fertilizer, comprising a support frame 1, a fermentation tank 2, a stirring mechanism 3, a power mechanism 4, and an air intake mechanism 5.

[0019] Fermentation tank 2 is mounted on support 1 and has an inlet and an outlet; stirring mechanism 3 is rotatably mounted inside fermentation tank 2; power mechanism 4 is mounted on support 1 and the power device drives stirring mechanism 3 to rotate; air intake mechanism 5 is mounted on fermentation tank 2.

[0020] Fermentation tank 2 is a container for organic fertilizer fermentation. Fermentation tank 2 is a tank-shaped body that is welded to support frame 1 with legs to elevate the position of fermentation tank 2. A temperature control system should be installed on fermentation tank 2 to maintain a suitable reaction temperature of about 50°C. Fermentation tank 2 is equipped with an inlet and an outlet. The inlet is used for material feeding, and a feeder should be arranged on the inlet side accordingly. The outlet is used to discharge the mixed and fermented organic fertilizer. The stirring mechanism 3 is driven to rotate by the torque generated by the power mechanism 4. The stirring mechanism 3 agitates the material, allowing the material to fully contact with air, so that the microorganisms can better ferment the organic fertilizer. The air intake mechanism 5 is used to provide air to the fermenting material. The forced air intake of the air intake mechanism 5 accelerates the fermentation.

[0021] According to the instruction manual Figure 1-3 It can be seen that the above-mentioned air intake mechanism 5 includes a forced air intake pipe 51, an air supply component 52, and a circulating flow divider 53; the forced air intake pipe 51 is installed on the fermenter 2, the circulating flow divider 53 connects the forced air intake pipe 51 and the air supply component 52, the circulating flow divider 53 is embedded in the fermenter 2, and the circulating flow divider 53 divides the air intake of the forced air intake pipe 51 into the fermenter 2.

[0022] The forced air intake pipe 51 serves as the main air intake channel, arranged along the length of the fermentation tank 2 and close to the top of the fermentation tank 2. The forced air intake is generated by the air supply component 52, which can be a blower. The air is introduced into the forced air intake pipe 51 through the air supply component 52, and then into the circulating flow divider 53. The circulating flow divider 53 diverts the air intake and discharges it into the fermentation tank 2. By increasing the air intake, the air can fully contact the diatom-based organic fertilizer raw materials in the fermentation tank 2, thereby improving the fermentation efficiency.

[0023] In some embodiments of this application, the circulating flow divider 53 includes an embedded ring 531, an exhaust chamber 532, and a plurality of exhaust holes 533; the embedded ring 531 is embedded in the fermenter 2, the embedded ring 531 has an exhaust chamber 532 inside, and the exhaust chamber 532 is connected to the forced air intake pipe 51, and a plurality of exhaust holes 533 are evenly distributed on the embedded ring 531 and communicate with the exhaust chamber 532.

[0024] The embedded ring 531 is embedded in the inner wall of the fermentation tank 2 and connected to the forced air intake pipe 51 through the exhaust chamber 532. The air supply component 52 sends the airflow into the exhaust chamber 532 through the forced air intake pipe 51, and then diffuses the air into the fermentation tank 2 through multiple exhaust holes 533. By increasing the air intake, the air can fully contact the organic fertilizer fermentation material, thereby improving the fermentation efficiency of the organic fertilizer.

[0025] In some embodiments of this application, the embedded ring 531 is a notched annular plate. An embedded groove is provided at the top of the fermentation tank 2, and the embedded ring 531 is fitted into the embedded groove to make the inner wall of the fermentation tank 2 flat. By the notched annular structure of the embedded ring 531 cooperating with the embedded groove, the shape of the inner wall of the fermentation tank 2 is kept intact, so as to avoid affecting the efficiency of material movement. At the same time, the embedded ring 531 is arranged at the top of the fermentation tank 2 to prevent material particles from entering the exhaust chamber 532 of the embedded ring 531.

[0026] In some embodiments of this application, a protective net 534 is installed on the exhaust hole 533 to cover the exhaust hole 533 and protect the inside of the exhaust hole 533 to prevent external organic fertilizer from entering the exhaust chamber 532.

[0027] In some embodiments of this application, the stirring mechanism 3 includes an auger 31 and a coupling 32; the auger 31 is rotatably mounted on the fermentation tank 2, and a coupling 32 is provided at one end of the auger 31.

[0028] The power unit 41 is connected to the coupling 32, so that the power unit 41 drives the auger 31 device, so that the auger 31 can fully stir and mix the materials in the fermentation tank 2.

[0029] In some embodiments of this application, the power mechanism 4 includes a connected power unit 41 and a transmission unit 42, the power unit 41 and the transmission unit 42 are mounted on the bracket 1, and the transmission unit 42 is connected to the coupling 32.

[0030] The power unit 41 drives the transmission unit 42 to rotate. The transmission unit 42 adopts a reduction gear set. The output torque is increased by the transmission of the reduction gear set. The reduction gear set is connected to the output shaft, and the output shaft is connected to the coupling 32. The torque output by the power unit 41 is amplified by the reduction gear set to drive the auger 31 to rotate, so as to agitate the material.

[0031] The fermentation device for diatom-based organic fertilizer using the above-mentioned technical solution significantly increases the air intake through the forced air intake mechanism 5, and achieves efficient mixing of materials and air with the auger 31 to accelerate microbial fermentation; the embedded ring 531 type circulating flow divider 53 is embedded in the embedded groove at the top of the fermentation tank 2, and the exhaust hole 533 is equipped with a protective net 534, which ensures uniform air diffusion and prevents material blockage.

[0032] Work Process: The working process of this diatom-based organic fertilizer fermentation device can be broken down into the following steps: First, the material is fed into the fermentation tank 2 through the inlet at the top. A feeding machine can be installed at the inlet to achieve continuous or batch feeding. After the material enters the fermentation tank 2, the temperature control system is activated simultaneously. The built-in heating / cooling jacket or sensors monitor and adjust the temperature inside the tank in real time to maintain a microbial active temperature range of about 50°C, ensuring a stable fermentation environment. Subsequently, the power motor 41 in the power mechanism 4 is started. After the torque is amplified by the transmission device 42, it drives the auger 31 stirring mechanism 3 inside the fermentation tank 2 to rotate at a low speed through the coupling 32. During the stirring process, the blades of the auger 31 lift the material at the bottom upward and push the material at the top downward, forming a circulating convection, which fully disperses the material particles and exposes them to the air. Simultaneously, the air supply component 52 of the air intake mechanism 5 begins to operate, delivering external air through the forced air intake pipe 51 along the length of the fermentation tank 2 to the top-mounted circulating distributor 53. The circulating distributor 53 adopts a notched annular embedded ring 531 structure, embedded in a pre-set embedded groove on the inner wall of the fermentation tank 2. Its internal exhaust chamber 532 is connected to the forced air intake pipe 51. After the air enters the exhaust chamber 532, it is evenly diffused into the tank through multiple exhaust holes 533 evenly distributed on the surface of the embedded ring 531. The exhaust holes 533 are equipped with protective nets 534 to effectively prevent material particles from entering and avoid clogging the exhaust chamber 532. The forced air intake and the agitator 31 create a synergistic effect: the air is divided by the circulating distributor 53 to form multiple fine airflows, which fully contact the material vortex generated by the agitator 31, increasing the gas-solid contact area, accelerating the penetration of oxygen into the material, promoting the metabolic activity of aerobic microorganisms, and thus significantly improving the fermentation rate. During fermentation, the temperature control system continuously and dynamically adjusts the heating or cooling intensity according to the microbial growth stage. For example, in the early stage of fermentation, the temperature is appropriately increased to activate the inoculum; in the middle stage, a constant temperature is maintained to promote decomposition; and in the later stage, the temperature may be appropriately lowered to avoid over-fermentation. After fermentation is complete, the mature organic fertilizer is discharged through the outlet at the bottom of fermentation tank 2. The outlet can be connected to a conveyor belt or packaging equipment to achieve automated discharge.
