Description

Technical Field

[0001] This invention relates to the field of composting fermentation technology, and more specifically to an indoor composting fermentation box with mechanical turning function. Background Technology

[0002] Aerobic composting is an environmentally friendly method of transforming organic waste into stable humus through the action of microorganisms. Traditional outdoor composting methods require a large area, are easily affected by weather, and may attract insects and produce odors, making them unsuitable for indoor environments with strict hygiene and space requirements. Existing small-scale indoor composting devices are typically small in size and rely mainly on natural ventilation or simple passive ventilation. Insufficient oxygen supply can easily lead to an anaerobic environment inside the compost pile, resulting in slow fermentation and foul odors.

[0003] Furthermore, turning the compost pile is a crucial step in the composting process, playing a vital role in mixing materials, breaking up clumps, dissipating heat, and replenishing oxygen. However, manual turning is extremely inconvenient in small, enclosed containers, leading users to often skip this step, which severely impacts composting efficiency and quality. Simultaneously, the ventilation structures of existing composting equipment are prone to clogging due to biofilm and dust after a period of use, and removing materials after fermentation is inconvenient. Therefore, there is an urgent need to develop a miniaturized, intelligent composting device suitable for indoor environments, capable of automatic turning, maintaining continuous and efficient ventilation, and facilitating maintenance and cleaning. This would overcome the shortcomings of existing technologies and promote the effective application of aerobic composting technology in laboratories, homes, and other settings. Summary of the Invention

[0004] In view of this, the present invention provides an indoor composting fermentation box with mechanical turning function, aiming to solve the problem of inconvenient turning in existing indoor composting equipment. To achieve the above objective, the present invention adopts the following technical solution: This invention provides an indoor composting fermentation box with mechanical turning function, comprising: The box body has a partition plate inside. The two ends of the partition plate are respectively connected to a pair of parallel inner walls of the box body. One side of the partition plate is an installation chamber, and the other side of the partition plate is a fermentation chamber. The upper end of the installation chamber is provided with a top cover plate, which is connected to the box body. One side of the fermentation chamber is provided with a door, which is rotatably connected to the box body. The upper end of the fermentation chamber is provided with a sealing plate, which has a feed inlet. The sealing plate is rotatably connected to the top cover plate.

One end of the air intake pipe is located inside the air intake chamber, and the other end of the air intake pipe is located inside the fermentation chamber. Multiple air outlets are provided on the pipe wall at the end of the air intake pipe away from the air intake chamber. The air intake pump is connected to the outer wall of the box body, and the output end of the air intake pump extends into the air intake chamber.

[0006] Furthermore, a partition plate for holding compost is provided below the drive shaft. The two ends of the partition plate are respectively connected to a pair of parallel inner walls of the fermentation chamber. The partition plate is provided with multiple drainage holes.

[0007] Furthermore, each of the two parallel inner walls of the fermentation chamber is provided with a slide rail, and the partition plate is slidably connected within the slide rail.

[0008] Furthermore, a drain outlet is provided at the bottom of the fermentation chamber.

[0009] Furthermore, it also includes an exhaust pipe and a filter device.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] See Figure 1-5 This invention discloses an indoor composting fermentation box with mechanical turning function, comprising: Box 4, with a partition plate 13 inside the box 4. The two ends of the partition plate 13 are connected to a pair of parallel inner walls of the box 4. One side of the partition plate 13 is an installation chamber, and the other side of the partition plate 13 is a fermentation chamber. The upper end of the installation chamber is provided with a top cover plate 1, which is connected to the box 4. One side of the fermentation chamber is provided with a door 3, which is rotatably connected to the box 4. The upper end of the fermentation chamber is provided with a sealing plate 2, which has a feed inlet. The sealing plate 2 is rotatably connected to the top cover plate 1. The turning mechanism includes a motor 14 and a drive shaft 15. The motor 14 is installed in the installation chamber and is fixedly connected to the installation chamber. The output shaft of the motor 14 is connected to the drive shaft 15. The output end of the drive shaft 15 extends into the fermentation chamber through the partition plate 13. The drive shaft 15 is rotatably connected to the partition plate 13. A spiral blade 10 is provided on the drive shaft 15.

[0024] In some embodiments, a sealing strip is installed on the inner wall of the feed inlet, and a blocking plate is provided at the feed inlet.

[0025] Fertilizer is placed into the fermentation chamber through the feed inlet, and the chamber door 3 is closed. The sealing strip and sealing plate keep the fertilizer in a sealed environment to prevent odor from escaping. After the fertilizer has fermented for a period of time, the motor 14 is started. The motor 14 drives the transmission shaft 15 to rotate, which in turn drives the spiral blade 10 to rotate. The spiral blade 10 cuts large fertilizer particles and turns the fertilizer over, changing its position so that it comes into contact with oxygen, increasing the oxygen content inside the compost and ensuring the quality of fermentation.

[0026] In some embodiments, the output shaft of the motor 14 is connected to a screw rod 21, the output end of the screw rod 21 passes through the partition plate 13 and enters the fermentation chamber, the screw rod 21 is rotatably connected to the partition plate 13, and the part of the screw rod 21 located in the fermentation chamber is spiral-shaped.

[0027] The fertilizer inside the box 4 is turned over by the screw rod 21 to ensure that the fertilizer inside the box 4 is turned over thoroughly.

[0028] In some embodiments, the system further includes an upper enclosure 17, a side enclosure 18, and an air pump 7. The upper enclosure 17 and the side enclosure 18 enclose the inner wall of the fermentation chamber to form an air intake chamber. The upper enclosure 17 is provided with a plurality of through holes, and an air intake pipe 12 is installed in the through holes. The air intake pipe 12 is connected to the upper enclosure 17. One end of the air intake pipe 12 is located in the air intake chamber, and the other end of the air intake pipe 12 is located in the fermentation chamber. A plurality of air outlet holes are provided on the pipe wall at the end of the air intake pipe 12 away from the air intake chamber. The air pump 7 is connected to the outer wall of the box 4, and the output end of the air pump 7 extends into the air intake chamber.

[0029] During the composting fermentation process, oxygen is pumped into the air intake chamber by the air intake pump 7. The oxygen in the air intake chamber flows along the air intake pipe 12 and finally enters the fermentation chamber through the air outlet, thereby replenishing the oxygen in the fermentation chamber, ensuring sufficient oxygen during the fermentation process, and ensuring the fermentation quality.

[0030] In some embodiments, a composting partition plate 8 is provided below the drive shaft 15. The two ends of the partition plate 8 are respectively connected to a pair of parallel inner walls of the fermentation chamber, and the partition plate 8 is provided with a plurality of drainage holes.

[0031] Fertilizer is added to the partition plate 8 through the feed inlet. The liquid in the fertilizer flows through the drain hole to the bottom of the partition plate 8, thus achieving the separation of solid and liquid.

[0032] In some embodiments, slide rails are provided on a pair of parallel inner walls of the fermentation chamber, and the partition plate 8 is slidably connected in the slide rails.

[0033] In some instances, a baffle 16 is connected to the end of the slide rail away from the door 3.

[0034] In some instances, when collecting fertilizer, the collection box 9 is placed below the partition plate 8.

[0035] Place both ends of the partition plate 8 into the slide rail, push the partition plate 8 to slide it in the slide rail until the end of the partition plate 8 away from the door 3 abuts against the baffle 16, thus completing the installation of the partition plate 8.

[0036] When collecting the fermented fertilizer, the partition plate 8 is pulled out from the slide rail. At this time, the fertilizer on the partition plate 8 falls into the collection box 9, realizing the rapid collection of fertilizer.

[0037] In some embodiments, a drain outlet is provided at the bottom of the fermentation chamber.

[0038] The liquid separated from the fertilizer is discharged through the drain port.

[0039] In some embodiments, the system further includes an exhaust pipe 5 and a filter device 6. The filter device 6 is connected to the outer wall of the housing 4, and the exhaust pipe 5 is connected to the side wall of the housing 4. One end of the exhaust pipe 5 is connected to the fermentation chamber, and the other end of the exhaust pipe 5 is connected to the input end of the filter device 6.

[0040] In some embodiments, activated carbon is provided inside the filtration device.

[0041] The gas inside the fermentation chamber flows into the filter device 6 through the gas outlet pipe 5. The activated carbon adsorbs the organic waste gas and odor in the gas. After being filtered by the filter device 6, the gas is discharged into the outside air, ensuring the oxygen content of the air inside the fermentation chamber, thereby ensuring the fermentation quality.

[0042] In some embodiments, a vent is provided on the side wall of the fermentation chamber, a filter screen 22 is provided at the vent, and the end of the air outlet pipe 5 away from the filter device 6 is connected to the vent.

[0043] In some embodiments, a lifting head 11 is provided at the end of the air intake pipe 12 away from the air intake chamber.

[0044] In some embodiments, the outer wall of the intake pipe 12 near the intake chamber is provided with threads, and the through hole is provided with threads, and the intake pipe 12 and the through hole are connected by threads.

[0045] When the air outlet is blocked by fertilizer, rotate the lifting head 11 to rotate the air inlet pipe 12, thereby unscrewing the air inlet pipe 12 out of the air inlet chamber, separating the air inlet pipe 12 from the upper enclosure plate 17, removing the air inlet pipe 12 from the fermentation box, cleaning the air inlet pipe 12, and then screwing the air inlet pipe 12 back into the air inlet chamber. The connection between the air inlet pipe 12 and the air inlet chamber is made through the threaded connection, ensuring the ease of cleaning the air inlet pipe 12 and ensuring that oxygen can smoothly enter the fermentation chamber.

[0046] In some embodiments, an insulation layer is provided on the inner wall of the fermentation chamber.

[0047] The temperature inside the fermentation chamber is maintained by an insulation layer, ensuring the continued fermentation of the fertilizer.

[0048] In some embodiments, the system further includes a control system, an oxygen sensor 20, and a temperature sensor 19, both of which are connected to the inner wall of the fermentation chamber, and the oxygen sensor 20 and the temperature sensor 19 are electrically connected.

[0049] The oxygen sensor 20 measures the oxygen content in the fermentation chamber and transmits the electrical signal to the control system. When the control system shows that the oxygen content is low, the air intake pump 7 is started to deliver oxygen into the air intake chamber, thereby replenishing the oxygen in the fermentation chamber. The temperature sensor 19 detects the temperature in the fermentation chamber and transmits the electrical signal to the control system, which then displays the temperature.
