Description

Technical Field

[0001] This invention relates to the field of fermentation treatment equipment technology, and in particular to a vegetable straw resource-based fermentation treatment equipment. Background Technology

[0002] With the large-scale development of my country's vegetable planting industry, the annual output of vegetable straw has been increasing year by year. Data from the "China Agricultural Waste Industry Development Report" shows that my country's annual vegetable straw production has exceeded 200 million tons, with straw production in major greenhouse vegetable producing areas (such as Shandong, Henan, and Hebei) accounting for over 60%. This type of straw is characterized by high moisture content (70%–85%), easy rotting, and high fiber content (30%–45%). If not handled promptly, it can cause multiple problems.

[0003] Existing fermentation devices simply transport the processed raw materials to be fermented into the fermentation tank, without being able to accurately detect the moisture content of the fermenting material. If the moisture content is below 50%, the gaps between the straw particles are too large, preventing the full diffusion of enzymes secreted by microorganisms (such as cellulase), and hindering the transport of nutrients, resulting in a decrease in the metabolic rate of microorganisms of more than 50%. If the moisture content is above 60%, the gaps between the straw particles are filled with water, preventing oxygen from penetrating. Aerobic microorganisms (such as thermophilic bacteria) stop metabolizing due to lack of oxygen, while putrefactive bacteria (such as hydrogen sulfide-producing bacteria) multiply in large numbers, not only releasing foul-smelling gases (exacerbating the "environmental pollution problem" mentioned in the background technology), but also producing inhibitory substances such as organic acids, leading to the inactivation of functional bacteria such as methanogens and actinomycetes, and causing fermentation to fail directly. Therefore, this application proposes a vegetable straw resource-based fermentation treatment device. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the prior art that it is impossible to accurately detect and control the moisture content of fermented products, and to propose a vegetable straw resource-based fermentation treatment device.

[0006] Optionally, the adjusting mechanism includes a liquid storage tank fixedly installed on a first cavity, a heating cavity fixedly installed on the first cavity, the heating cavity being a hollow cavity, a guide pipe fixedly installed at one end of the liquid storage tank, a water pump fixedly installed at one end of the guide pipe, one end of the water pump communicating with the heating cavity, an annular pipe fixedly installed on the heating cavity, a blower fixedly installed on the first cavity, an air supply pipe fixedly installed on one side of the blower, the air supply pipe communicating with the annular pipe, a water supply cavity fixedly installed at the top of the first cavity, the water supply cavity being a hollow cavity, a plurality of equidistantly arranged circumferential atomizing nozzles fixedly installed at the bottom of the water supply cavity, a connecting pipe fixedly connected to the heating cavity, one end of the connecting pipe communicating with the water supply cavity, a short pipe fixedly installed at the top of the first cavity, an air pump fixedly installed at one end of the short pipe, a positioning pipe fixedly installed at the bottom of the air pump, a guide pipe fixedly installed at the bottom of the first cavity, the guide pipe having a plurality of through holes, and one end of the positioning pipe communicating with the bottom of the guide pipe.

[0007] Optionally, a sealing valve is fixedly installed at the bottom of the first cavity, and the sealing valve has multiple discharge ports. A reciprocating screw is rotatably installed in the second cavity, and the reciprocating screw is fixedly connected to a rotating shaft. A guide block is slidably installed at the bottom of the sealing valve. The guide block is tapered, and multiple unblocking rods are fixedly installed on the guide block.

[0009] Optionally, the water pump and blower are equipped with a controller, the output terminal of the humidity sensor is connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the start terminal of the water pump and blower.

[0010] Optionally, a plurality of guide rods are fixedly installed at the bottom of the sealing valve, and the guide rods are slidably connected to the guide block.

[0011] Optionally, a high-pressure nozzle is fixedly installed on one side of the humidity sensor, and the high-pressure nozzle is connected to the annular pipe.

[0014] Optionally, an electronic valve is fixedly installed on the fixed tube, and the electronic valve is provided with anti-slip texture.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention delivers pretreated fermentation raw materials into a first chamber, and a starting motor drives the rotating shaft to rotate. The stirring blades stir the materials in the first chamber, allowing the humidity sensor to dynamically detect the moisture content of the materials inside, thereby improving the accuracy of the detection.

[0016] Furthermore, by processing the detection results and transmitting them to the controller of the water pump or blower, when the humidity sensor detects a moisture content higher than 60%, it sends a signal to the drive end of the blower, which starts and delivers filtered air into the annular pipe. The annular pipe is heated by a heating chamber, which heats the air inside. The heated gas is then delivered into a high-pressure nozzle and discharged to accelerate moisture evaporation. At the same time, it blows air onto the surface of the sensor to prevent impurities from accumulating. The heated air is then discharged into the fermentation material to keep the air temperature consistent with the optimal fermentation temperature of the fermentation bacteria, preventing the temperature from being too low and affecting the activity of the fermentation bacteria and the fermentation process. When the humidity sensor detects a moisture content lower than 50%, it sends a signal to the water pump, which delivers water from the storage tank into the heating chamber. Simultaneously, the heated water in the heating chamber is delivered from the connecting pipe into the water delivery chamber, and then discharged into the first chamber through the atomizing nozzle, preventing the water temperature from being too low and affecting the activity of the fermentation bacteria.

[0017] Furthermore, by opening the sealing valve, the rotating shaft drives the reciprocating screw to rotate, and the unblocking rod on the guide block continuously unblocks the material in the discharge port on the sealing valve to prevent material blockage. At this time, the material in the first chamber is emptied into the second chamber. Then, the material to be fermented is added to the first chamber. The ammonia produced by the anaerobic fermentation in the second chamber is collected by the conveying and collecting pipe. The collected ammonia is conveyed into the biogas burner by the connecting valve for combustion. The heat generated after combustion is conveyed into the heating chamber through the guide pipe to heat the internal liquid and reduce the power supply of the heating chamber.

[0018] This invention enables precise detection of the moisture content of fermented materials, reduces the impact of the environment on the activity of fermenting bacteria, improves fermentation effect, increases processing efficiency, and reduces energy consumption. Attached Figure Description

[0027] Example 1 like Figure 1-2As shown, the present invention proposes a vegetable straw resource utilization fermentation treatment device, comprising a first chamber 1, which is a micro-aerobic fermentation zone for preliminary fermentation of straw, and a second chamber 2, which is an anaerobic fermentation zone. The second chamber 2 is fixedly installed at the bottom of the first chamber 1. A liquid storage tank 3 is fixedly installed on the first chamber 1. A rotating shaft 25 is rotatably installed inside the first chamber 1. Multiple circumferentially arranged stirring blades 26 are fixedly installed at equal intervals on the rotating shaft 25. The rotating shaft drives the stirring blades 26 to rotate. Humidity control devices are fixedly installed at the top and bottom of the inner wall of the first chamber 1. Sensor 28, the humidity sensor 28, sets the threshold for material moisture content to 50%-60%, and is used to accurately detect the moisture content of the fermentation product. In conjunction with the rotation, the material is rotated, and the humidity sensor 28 dynamically monitors the material. The detection result is the average value of the humidity sensors 28 above and below. A vent valve 12 is fixedly installed on the first chamber 1, which is used to discharge the internal gas. The first chamber 1 is provided with an adjustment mechanism for accurately controlling the moisture content of the internal fermentation product.

[0028] Example 2 like Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the regulating mechanism includes a storage tank 3 fixedly installed on the first cavity 1. A heating chamber 16 is fixedly installed on the first cavity 1 to heat the fermentation material inside the first cavity 1, helping it to ferment better. The heating chamber 16 is a hollow cavity containing water, maintained at a temperature between 35-45 degrees Celsius. A guide pipe 4 is fixedly installed at one end of the storage tank 3, and a water pump 5 is fixedly installed at the other end of the guide pipe 4. One end of the water pump 5 is connected to the heating chamber 16. An annular pipe 17 is fixedly installed on the heating chamber 16. A blower 6 is fixedly installed on the first cavity 1, and a gas supply pipe 7 is fixedly installed on one side of the blower 6, connecting to the annular pipe 17. A water delivery chamber 24 is fixedly installed at the top of the first cavity 1. The water delivery chamber 24 is a hollow cavity. Multiple atomizing nozzles 27 arranged equidistantly in a circular pattern are fixedly installed at the bottom of the water delivery chamber 24. A connecting pipe 15 is fixedly connected to the heating chamber 16, with one end of the connecting pipe 15 connected to the water delivery chamber 24. A short pipe 13 is fixedly installed at the top of the first cavity 1. An air pump 14 is fixedly installed at one end of the short pipe 13. A positioning pipe is fixedly installed at the bottom of the air pump 14. An air guide pipe 30 is fixedly installed at the bottom of the first cavity 1. The air guide pipe 30 has multiple through holes. One end of the positioning pipe is connected to the bottom of the air guide pipe 30. The air pump 14 delivers the gas generated during fermentation into the bottom of the fermenting material, thus purifying the bottom. Heating is performed while the fermentation gas contains oxygen, supplying oxygen to the fermenting material at the bottom and preventing oxygen deficiency caused by accumulation at the bottom. A controller is installed inside the water pump 5 and blower 6. The output of the humidity sensor 28 is connected to the input of the controller, and the output of the controller is electrically connected to the start-up terminals of the water pump 5 and blower 6. When the humidity sensor 28 detects a moisture content higher than 60%, it transmits a signal to the drive terminal of the blower 6, starting the blower 6 and delivering filtered air into the annular pipe 17. The interior of the annular pipe 17 is heated by the heating chamber 16, heating the internal air. The heated gas is then discharged through the high-pressure nozzle 29, further heating the internal gas. The air is rapidly discharged, accelerating internal airflow and water evaporation. Simultaneously, the surface of the sensor is blown to improve detection accuracy and prevent impurity accumulation. The heated air is discharged into the fermentation material to keep the air temperature consistent with the optimal fermentation temperature of the fermentation bacteria, preventing the activity of the fermentation bacteria from being affected by excessively low temperatures and thus affecting fermentation. When the humidity sensor 28 detects that the moisture content is below 50%, it transmits a signal to the water pump 5. The water pump 5 delivers water from the storage tank 3 into the heating chamber 16. At the same time, the heated water in the heating chamber 16 is delivered from the connecting pipe 15 into the water delivery chamber 24, and then discharged into the first chamber 1 by the atomizing nozzle 27, preventing the activity of the fermentation bacteria from being affected by excessively low water temperature.

[0029] Example 3 like Figure 4 , Figure 5 and Figure 7As shown, a sealing valve 32 is fixedly installed at the bottom of the first chamber 1 to seal the first chamber 1 and the second chamber 2. The sealing valve 32 has multiple discharge ports 31 for conveying the fermented material from the first chamber 1 into the second chamber 2 for anaerobic fermentation. A reciprocating screw 33 is rotatably installed inside the second chamber 2 and is fixedly connected to a rotating shaft 25. A guide block 34 is slidably installed at the bottom of the sealing valve 32. The guide block 34 is tapered, and multiple unblocking rods 3 are fixedly installed on the guide block 34. 5. One end of the unblocking rod 35 is tapered and located at the bottom of the discharge port 31. When it is necessary to transport the material in the first chamber 1 into the second chamber 2, the rotating shaft 25 is rotated. The rotating shaft 25 drives the stirring blade 26 to rotate, causing the internal material to flow. The sealing valve 32 is opened, and the rotating shaft 25 rotates, driving the reciprocating screw 33 to rotate. The reciprocating screw 33 drives the guide block 34 to make vertical reciprocating motion. The unblocking rod 35 on the guide block 34 continuously unblocks the material in the discharge port 31 on the sealing valve 32, preventing the material from flowing out. To prevent material blockage, a fixed pipe 18 is fixedly installed on one side of the second chamber 2. A collection tank 20 is fixedly installed at one end of the fixed pipe 18. A connecting valve 21 is fixedly installed on the top of the collection tank 20. A biogas burner 22 is fixedly installed at one end of the connecting valve 21. A heat-conducting pipe 23 is fixedly installed on one side of the biogas burner 22. One end of the heat-conducting pipe 23 is fixedly connected to the heating chamber 16. The ammonia gas produced by fermentation in the second chamber 2 is transported into the collection tank 20 for collection. The collected ammonia gas is then transported to the biogas burner 22 by the connecting valve 21. Combustion takes place inside the chamber, and the heat generated after combustion is transferred from the heat pipe 23 into the heating chamber 16 to heat the internal liquid and reduce the power supply of the heating chamber 16. Multiple guide rods 36 are fixedly installed at the bottom of the sealing valve 32, and the guide rods 36 are slidably connected to the guide block 34. A high-pressure nozzle 29 is fixedly installed on one side of the humidity sensor 28 and is connected to the annular pipe 17. An air inlet 8 is fixedly installed on one side of the blower 6, and a filter screen is provided on the air inlet 8 to filter the air entering the first chamber 1.

[0030] A motor 9 is fixedly installed on the first cavity 1. A first gear 11 is rotatably installed on the first cavity 1. A second gear 10 is rotatably installed on one side of the first gear 11. The first gear 11 and the second gear 10 mesh. The output shaft of the motor 9 is fixedly connected to the first gear 11. One end of the rotating shaft 25 is fixedly connected to the second gear 10. When the motor 9 starts, it drives the second gear 10 to rotate. The second gear 10 drives the first gear 11 to rotate. The first gear 11 drives the rotating shaft to rotate. An electronic valve 19 is fixedly installed on the fixed pipe 18. The electronic valve 19 is provided with anti-slip texture and is used to transport the gas produced by anaerobic fermentation.

[0031] Working principle: The pre-treated raw materials are fed into the first chamber 1. The motor 9 is started, and the output shaft of the motor 9 drives the second gear 10 to rotate. The second gear 10 drives the first gear 11 to rotate, and the first gear 11 drives the rotating shaft 25 to rotate. The stirring blades 26 on the rotating shaft 25 drive the material to rotate. The humidity sensor 28 dynamically detects the moisture content of the fermentation material in the first chamber 1. When the humidity sensor 28 detects that the moisture content is higher than 60%, it transmits a signal to the drive end of the blower 6. The blower 6 starts and delivers the filtered air into the annular pipe 17. The internal heating chamber 16 heats the air inside the fermentation material. The heated air is then pumped into the high-pressure nozzle 29 and discharged, accelerating the expulsion of internal gas and airflow, thus speeding up moisture evaporation. Simultaneously, the air blows across the sensor surface, improving detection accuracy and preventing impurity accumulation. The heated air is then released into the fermentation material, ensuring the air temperature matches the optimal fermentation temperature for the fermenting bacteria, preventing excessively low temperatures from affecting their activity and fermentation. When the humidity sensor 28 detects a moisture content below 50%, it transmits a signal to the water pump 5, which then pumps the liquid from the storage tank... Water from chamber 3 is fed into heating chamber 16, while heated water from heating chamber 16 is fed into water supply chamber 24 via connecting pipe 15, and then discharged into first chamber 1 via atomizing nozzle 27. This prevents the water temperature from being too low and affecting the activity of fermentation bacteria. After the aerobic fermentation in first chamber 1 is completed, sealing valve 32 is opened, and rotating shaft 25 drives reciprocating screw 33 to rotate. Reciprocating screw 33 drives guide block 34 to perform vertical reciprocating motion. The unblocking rod 35 on guide block 34 continuously unblocks the material in discharge port 31 on sealing valve 32 to prevent material blockage. At this time, first chamber 1... The material in chamber 1 is emptied into the second chamber 2. At this time, the material to be fermented is added back into chamber 1. The ammonia produced by the anaerobic fermentation in chamber 2 is collected in the collection tank 20. The collected ammonia is then transported to the biogas burner 22 for combustion via the connecting valve 21. The heat generated after combustion is transported into the heating chamber 16 through the heat pipe 23 to heat the internal liquid, reducing the power supply to the heating chamber 16. This enables accurate detection of the moisture content of the fermented material, reduces the impact of the environment on the activity of the fermenting bacteria, improves the fermentation effect, increases processing efficiency, and reduces energy consumption.
