Description

Technical Field

[0001] The utility model relates to the technical field of aerobic fermentation treatment of kitchen waste, and particularly relates to an automatic material feeding component and a strain cultivation device applying the component. Background Art

[0002] The working principle of the aerobic fermentation treatment technology for kitchen waste is to mix kitchen waste and biomass auxiliary materials evenly in a certain proportion, and in the fermentation tank, by adjusting the moisture, microbial inoculant, oxygen content and temperature change of the mixed materials, the materials are subjected to sufficient aerobic fermentation decomposition. The heat released during the decomposition process can increase the temperature of the kitchen waste itself, and part of the organic matter is decomposed, achieving the purpose of reducing the amount of kitchen waste. Through ventilation, oxygenation, stirring and other functions, the garbage treatment equipment can ensure that the highest temperature reaches the relevant standard requirements, and can kill a large number of pathogenic bacteria and parasites in the kitchen waste heap body. At the same time, the odor removal system is used to deodorize the discharged gas to achieve the purpose of harmless treatment of kitchen waste. The products after aerobic fermentation of kitchen waste can be further processed and used for soil improvement, landscaping, organic fertilizer raw materials, etc.

[0003] In the existing kitchen waste treatment equipment and technology, biomass auxiliary materials, microbial inoculants, and additives such as brown sugar water are all added manually. According to the fermentation situation of the discharged fertilizer, the fermentation quality is judged artificially, and the auxiliary materials, microbial agents, etc. are added by opening the bin body. The workload is large, the operation is inconvenient, and the fermentation quality is affected.

[0004] During the fermentation process, the artificial addition of auxiliary materials, inoculants, etc. will have a greater impact on the high-temperature aerobic fermentation of kitchen waste, mainly manifested in:

[0005] (1) Manually opening the fermentation tank to add auxiliary materials causes the temperature in the tank to drop, reducing the environmental temperature of high-temperature aerobic fermentation and reducing the activity of microorganisms.

[0006] (2) It increases the labor cost because auxiliary materials, inoculants, and other additives need to be added manually, and personnel need to be continuously arranged to observe the fermentation quality and judge the addition time and quantity of additives.

[0007] To sum up, it will affect the quality of the output organic fertilizer. Due to the phenomena of untimely addition, excessive addition or insufficient addition of auxiliary materials, microbial inoculants, etc., the high-temperature aerobic fermentation of kitchen waste is not thorough, harmful substances cannot be completely reacted and eliminated, and the quality of the output organic matter is defective or does not meet the standards.

[0008] Therefore, it is particularly important to urgently design an automatic material feeding component and a strain cultivation device applying the component to solve the above defects. Summary of the Utility Model

[0025] Embodiment:

[0026] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0027] An automatic material feeding assembly, comprising a fermentation tank 1 and a material feeding hopper 2. The fermentation tank 1 is composed of a tank body 3, a mounting bracket 4, a stirring device 5, an internal partition plate 6 in the tank, an organic fertilizer discharge port 7, a driving motor 8, and a chain 9. The mounting bracket 4 is fixedly installed on the outer side of the tank body 3. The stirring device 5 is fixedly installed inside the mounting bracket 4. The internal partition plate 6 in the tank is fixedly installed inside the tank body 3 and is located outside the stirring device 5. The organic fertilizer discharge port 7 is opened at the bottom end of the tank body 3. The driving motor 8 is fixedly installed on the inner side of the mounting bracket 4 and is located below the tank body 3. The driving motor 8 and the stirring device 5 are connected by a chain 9 for transmission. The material feeding hopper 2 is fixedly installed on the top of the tank body 3 and is located inside the mounting bracket 4.

[0028] First of all, the stirring device 5 includes a rotating shaft 501 rotatably connected inside the tank body 3. A spiral stirring paddle 502 is fixedly installed on the outer side of the rotating shaft 501. A through groove is opened inside the internal partition plate 6 in the tank and is located outside the spiral stirring paddle 502. The bottom of the driving motor 8 is fixedly connected to the mounting bracket 4 through a frame 801. A driving gear 802 is fixedly installed on the driving end of the driving motor 8. A driven gear 803 is fixedly installed on the right end of the rotating shaft 501 and is located outside the tank body 3. The chain 9 is located outside the driving gear 802 and the driven gear 803. After the solid residue of the food waste is pressed and enters the inside of the tank body 3, and after adding the auxiliary materials in the tank body 3 to the preset addition amount, the driving motor 8 is started to drive the driving gear 802 to rotate. Driven by the chain 9, the driven gear 803 is driven to rotate, thereby driving the rotating shaft 501 inside the tank body 3 to rotate. The spiral stirring paddle 502 on the outer side of the rotating shaft 501 is used to fully stir the added auxiliary materials and the food waste solid residue, so as to reach the best state of high-temperature aerobic fermentation.

[0029] Furthermore, a discharge pipe 701 is fixedly installed at a position on the outer side of the tank body 3 corresponding to the outer side of the organic fertilizer discharge port 7. The organic fertilizer generated by high-temperature aerobic fermentation in the tank body 3 is discharged through the organic fertilizer discharge port 7. An organic fertilizer automatic detection device is installed on the discharge pipe 701, which can timely conduct on-line detection of the discharged organic matter, including indicators such as moisture content, pH value, organic matter, heavy metals, etc. When the detected indicators do not meet the standard values of "Organic Fertilizer" (NY / T 525 - 2021), the detection automatically identifies and timely increases the addition amount of the auxiliary materials, so as to meet the organic fertilizer use standard.

[0030] Furthermore, the material feeding hopper 2 includes a brown sugar water feeding hopper 201, an auxiliary material feeding hopper 202, and a microbial inoculum feeding hopper 203. The brown sugar water feeding hopper 201, the auxiliary material feeding hopper 202, and the microbial inoculum feeding hopper 203 are all fixedly installed at the top inside the installation bracket 4. There are guide pipes 204 fixedly installed between the brown sugar water feeding hopper 201, the auxiliary material feeding hopper 202, the microbial inoculum feeding hopper 203 and the bin body 3. Lids 205 are hinged at the tops of the brown sugar water feeding hopper 201, the auxiliary material feeding hopper 202, and the microbial inoculum feeding hopper 203. Plug plates 206 are movably installed at the top of the bin body 3 and inside multiple groups of guide pipes 204. Electric control valves 207 are fixedly installed at the front ends of multiple groups of plug plates 206 and at the top of the bin body 3. After the solid residue of the kitchen waste is pressed and enters the bin body 3, a limit sensor is installed inside the bin body 3. When the material reaches the specified position, the limit sensor is triggered to transmit the material signal to the electric control valves 207 at the bottoms of the brown sugar water feeding hopper 201, the auxiliary material feeding hopper 202, and the microbial inoculum feeding hopper 202. The electric control 207 senses the signal and triggers the plug plate 206 to open, and the material automatically enters the bin body 3. When the auxiliary materials in the bin body 3 reach the preset addition amount, the plug plate 206 automatically closes, so as to automatically sense the addition amount of the materials in the bin body 3 and automatically complete the addition of auxiliary materials such as auxiliary materials, microbial inoculum, and brown sugar water. The degree of automation is high and no one needs to be on duty.

[0031] The present invention also provides a strain cultivation device, including an automatic material feeding component.

[0032] In this embodiment, the implementation scenario is specifically as follows: After the solid residue of the kitchen waste enters the bin 3 after pressing, a limit sensor is installed in the bin 3. When the material reaches the designated position, the limit sensor is triggered, and the material signal is transmitted to the electric control valves 207 at the bottoms of the brown sugar water dosing hopper 201, the auxiliary material dosing hopper 202, and the microbial inoculant dosing hopper 202. The electric control 207 senses the signal and triggers the opening of the flap 206, and the material automatically enters the bin 3. When the amount of the auxiliary material in the bin 3 reaches the preset addition amount, the flap 206 automatically closes, and the driving motor 8 is started to drive the driving gear 802 to rotate. Driven by the chain 9, the driven gear 803 rotates, thereby driving the rotating shaft 501 inside the bin 3 to rotate. The spiral stirring paddle 502 outside the rotating shaft 501 is used to fully stir the added auxiliary material and the solid residue of the kitchen waste to achieve the best state of high-temperature aerobic fermentation. The organic fertilizer generated by high-temperature aerobic fermentation in the bin 3 is discharged through the organic fertilizer discharge port 7. An automatic detection device for organic fertilizer is installed on the discharge pipe 701, which can timely conduct on-line detection of the discharged organic matter, including indicators such as moisture content, pH value, organic matter, and heavy metals. When the detected indicators do not meet the standard values of "Organic Fertilizer" (NY / T 525-2021), the detection automatically identifies and timely increases the addition amount of the auxiliary material to meet the use standard of the organic fertilizer. The whole operation process is simple and convenient. Compared with the existing manual feeding method for aerobic fermentation treatment of kitchen waste, the utility model can automatically sense the addition amount of the material in the fermentation bin, automatically complete the addition of auxiliary materials, microbial inoculants, brown sugar water and other auxiliary materials, with a high degree of automation and no need for on-site personnel. At the same time, an on-line detection device is installed at the organic fertilizer discharge port, which can realize the on-line detection of the indicators in the organic fertilizer. When the detection is unqualified, the electric control valve of the material dosing hopper can be automatically controlled to adjust the quantity of the added material to ensure that the produced organic fertilizer meets the standard.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
