[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] Specifically, it provides a high-temperature aerobic fermentation tank for rapidly reducing the moisture content of urban sludge, including a fermentation tank body with an aerobic fermentation trough on its top surface. A lifting bottom plate is installed inside the aerobic fermentation trough, and an oxygenation mechanism is evenly arranged inside the aerobic fermentation trough. The oxygenation mechanism introduces oxygen into the aerobic fermentation trough. The lifting bottom plate automatically discharges the dried and fermented sludge from the aerobic fermentation trough. A sensor module is installed on the oxygenation mechanism, which collects parameter data of the urban sludge in the aerobic fermentation trough in real time. Based on the parameter data, the amount of oxygen introduced into the aerobic fermentation trough by the oxygenation mechanism is controlled.

[0007] As a further aspect of the present invention: the surface of the lifting base plate is evenly provided with a plurality of cylindrical holes, each of the plurality of cylindrical holes is provided with a cylindrical sleeve, the surface of the cylindrical sleeve is provided with a leakage hole, the bottom of the lifting base plate is provided with a liquid collection box, and an output pipe is fixedly connected to one side of the liquid collection box.

[0008] As a further aspect of the present invention: a hydraulic cylinder is fixedly connected to the bottom edge of the lifting base plate, and the bottom end of the hydraulic cylinder is connected to a limit sleeve through a hydraulic rod. The limit sleeve is fixed to the bottom surface of the inner cavity of the fermentation tank body.

[0009] As a further embodiment of the present invention: the oxygenation mechanism includes an external fixed cylinder, a cylindrical groove that fits into the center of the top surface of the cylindrical sleeve, and a plurality of external ventilation holes on the side surface of the external fixed cylinder.

[0010] As a further aspect of the present invention: the external fixed cylinder is provided with an internal rotating cylinder, and the side surface of the internal rotating cylinder is provided with a plurality of internal ventilation holes, which are used to release oxygen when the internal ventilation holes correspond one-to-one with the external ventilation holes.

[0011] As a further aspect of the present invention: the interior of the built-in rotating cylinder is provided with an internal ventilation groove, the interior of the fermentation tank body is provided with a blower, the output end of the blower is connected to the internal ventilation groove, the bottom end of the built-in rotating cylinder is fixedly connected with a drive gear, and the interior of the fermentation tank body is provided with a drive mechanism near the drive gear.

[0012] As a further aspect of the present invention: the driving mechanism includes a first driving motor and a second driving motor, the output end of the first driving motor is engaged with a first gear ring through a gear, the output end of the second driving motor is engaged with a second gear ring through a gear, and the sides of the first gear ring and the second gear ring are respectively engaged with the corresponding driving gears.

[0013] As a further aspect of the present invention: the sensor module installed on the oxygenation mechanism includes a humidity sensor, a temperature sensor, and a pH sensor.

[0014] As a further aspect of the present invention: the sensor module collects parameter data of urban sludge in the aerobic fermentation tank in real time, including humidity data, temperature data and pH value data.

[0017] The beneficial effects of this invention are:

[0018] 1. In this invention, by setting a lifting bottom plate, after the urban sludge has completed high-temperature aerobic fermentation in the open cavity and reached the treatment standard, the lifting bottom plate can move upward inside the aerobic fermentation tank, automatically discharging the urban sludge from the aerobic fermentation tank. During the upward movement of the lifting bottom plate, the waste gas contained in the urban sludge is directly discharged under the action of extrusion pressure, ensuring that the pollution of the treated urban sludge is greatly reduced.

[0019] 2. In this invention, the oxygenation mechanism collects parameter data of urban sludge in the aerobic fermentation tank in real time. Then, based on the parameter data, the amount of oxygen supplied to the aerobic fermentation tank by the oxygenation mechanism is controlled to ensure that the oxygen content of the urban sludge in the aerobic fermentation tank is within a stable range. This keeps the urban sludge in the aerobic fermentation tank under a highly efficient aerobic fermentation state, greatly improving the aerobic fermentation efficiency and effect of urban sludge, ensuring the treatment effect of urban sludge, and reducing time costs.

Detailed Implementation

[0031] 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.

[0032] Example 1

[0033] like Figure 1 - Figure 9As shown, this invention discloses a high-temperature aerobic fermentation tank for rapidly reducing the moisture content of urban sludge, including a fermentation tank body 1, with an aerobic fermentation tank 2 on its top surface. It should be noted that the urban sludge can be directly poured into the aerobic fermentation tank 2 during collection for high-temperature aerobic fermentation. Urban sludge refers to sludge generated during urban life and the operation and maintenance of urban municipal facilities related to urban life activities. In this invention, it refers to sludge from sewage treatment plants, water supply plants, drainage pipes, and dredged sludge. A lifting base plate 3 is installed inside the aerobic fermentation tank 2. Clearly, the lifting base plate 3 and the aerobic fermentation tank 2 together form an open cavity for holding urban sludge. Once the urban sludge has undergone high-temperature aerobic fermentation in the open cavity and meets the treatment standards, the lifting base plate 3 can move upwards inside the aerobic fermentation tank 2, automatically discharging the urban sludge from inside the tank. During the upward movement of the lifting base plate 3, the waste gas contained in the urban sludge is directly discharged under pressure, ensuring a significant reduction in the pollution level of the treated urban sludge. The aerobic fermentation tank 2 is equipped with uniformly distributed additives... Oxygenation mechanism 4 introduces oxygen into the aerobic fermentation tank 2. It should be noted that during the high-temperature aerobic fermentation of the urban sludge inside the aerobic fermentation tank 2, oxygenation mechanism 4 can continuously supply oxygen to ensure the oxygen content of the urban sludge inside the aerobic fermentation tank 2, promoting the high-temperature aerobic fermentation of the urban sludge and improving the treatment efficiency of the urban sludge. The lifting bottom plate 3 automatically discharges the dried and fermented sludge from the aerobic fermentation tank 2. A sensor module is installed on the oxygenation mechanism 4, which collects real-time data on the urban sludge inside the aerobic fermentation tank 2. Based on the parameter data, the oxygen supply mechanism 4 is controlled to supply oxygen to the aerobic fermentation tank 2. It should be noted that the sensor module can collect the parameter data of the urban sludge in the aerobic fermentation tank 2 in real time. Then, the oxygen supply mechanism 4 is controlled to supply oxygen to the aerobic fermentation tank 2 according to the parameter data, so as to ensure that the oxygen content of the urban sludge in the aerobic fermentation tank 2 is within a stable range. This keeps the urban sludge in the aerobic fermentation tank 2 in a highly efficient aerobic fermentation state, which greatly improves the aerobic fermentation efficiency and effect of the urban sludge and ensures the treatment effect of the urban sludge.

[0034] Example 2

[0035] like Figures 1-9As shown, the surface of the lifting base plate 3 is evenly provided with several cylindrical holes, and a cylindrical sleeve 31 is installed in each of the cylindrical holes. A leakage hole 32 penetrates the surface of the cylindrical sleeve 31. It should be noted that a filter screen should be installed on the top surface of the leakage hole 32 to prevent sludge from entering and clogging the leakage hole 32. A collection box 33 is installed at the bottom of the lifting base plate 3, and an output pipe 34 is fixedly connected to one side of the collection box 33. It should be explained that when urban sludge with high water content is placed into the aerobic fermentation tank 2, the water in the urban sludge will flow downwards under gravity and finally enter through the leakage hole 32 on the cylindrical sleeve 31. The sludge is fed into the collection box 33, which can quickly reduce the water content of the urban sludge. It should also be noted that an activated carbon filter layer can be installed inside the leakage hole 32 so that the liquid water passing through the leakage hole 32 can meet the discharge standards. A water pump is installed in the collection box 33, and the output end of the water pump is connected to the output pipe 34 through a pipe. The specifications and installation position of the water pump are selected by those skilled in the art according to the specifications of the collection box 33, ensuring that the water pump can discharge the liquid water in the collection box 33 in a timely manner. The end of the output pipe 34 away from the collection box 33 is set at the location selected by those skilled in the art as needed.

[0036] A hydraulic cylinder 6 is fixedly connected to the bottom edge of the lifting base plate 3. The bottom end of the hydraulic cylinder 6 is connected to a limit sleeve 11 via a hydraulic rod. The limit sleeve 11 is fixed to the bottom surface of the inner cavity of the fermentation tank body 1. It should be noted that when the urban sludge in the aerobic fermentation tank 2 has completed high-temperature aerobic fermentation, that is, when the urban sludge in the aerobic fermentation tank 2 has achieved the treatment effect, the hydraulic cylinder 6 can be opened. Since the top end of the hydraulic cylinder 6 is fixedly connected to the bottom edge of the lifting base plate 3, and the limit sleeve 11 is fixed to the bottom surface of the inner cavity of the fermentation tank body 1, after the hydraulic cylinder 6 is opened, the output end of the hydraulic cylinder 6 can react through the hydraulic rod to the limit sleeve 11. The lifting base plate 3 moves upward along the side wall of the aerobic fermentation tank 2 on the sleeve 11. During the upward movement of the lifting base plate 3, the waste gas contained in the urban sludge is directly discharged under the action of extrusion pressure, ensuring that the pollution of the treated urban sludge is greatly reduced. The lifting base plate 3 also scrapes the side wall of the aerobic fermentation tank 2 to ensure that the urban sludge is cleaned. It should also be noted that when the top surface of the lifting base plate 3 is flush with the top surface of the port of the aerobic fermentation tank 2, the oxygenation mechanism 4 is also flush with the top surface of the lifting base plate 3 and the top surface of the port of the aerobic fermentation tank 2, which makes it easy for workers to directly remove the urban sludge from the top surface of the lifting base plate 3.

[0037] The oxygenation mechanism 4 includes an external fixed cylinder 41. A cylindrical groove that fits into the center of the top surface of the cylindrical sleeve 31 is provided. Several external ventilation holes 42 are provided on the side surface of the external fixed cylinder 41. It should be noted that because the cylindrical groove that fits into the center of the top surface of the cylindrical sleeve 31 is provided, when the lifting base plate 3 moves the cylindrical sleeve 31, the cylindrical sleeve 31 can slide freely along the side surface of the external fixed cylinder 41, ensuring that the external fixed cylinder 41 will not affect the movement of the cylindrical sleeve 31. In addition, when the cylindrical sleeve 31 slides upward along the side surface of the external fixed cylinder 41, the cylindrical sleeve 31 can directly scrape the side surface of the external fixed cylinder 41 to remove the urban silt on the side surface of the external fixed cylinder 41.

[0038] The external fixed cylinder 41 contains an internal rotating cylinder 43. The side surface of the internal rotating cylinder 43 has several internal vent holes 46, each corresponding to an external vent hole 42. It should be noted that because the internal vent holes 46 and external vent holes 42 correspond one-to-one, when the positions of the internal vent holes 46 and external vent holes 42 are aligned, oxygen from the internal vent holes 46 can directly enter the external vent holes 42. The internal rotating cylinder 43 can rotate freely inside the external fixed cylinder 41. When the internal vent holes 46 stop supplying oxygen to the external vent holes 42... The built-in rotating cylinder 43 can be rotated so that the position of the internal vent 46 on the built-in rotating cylinder 43 is offset from the position of the external vent 42. In this way, the urban sludge in the aerobic fermentation tank 2 cannot enter the internal vent 46 through the external vent 42, causing the internal vent 46 to become blocked. When the internal vent 46 supplies oxygen to the external vent 42, the position of the internal vent 46 corresponds to the position of the external vent 42, that is, they are connected. The high-pressure oxygen can also prevent the urban sludge in the external vent 42 from entering the internal vent 46, causing the internal vent 46 to become blocked.

[0039] The built-in rotating cylinder 43 has an internal ventilation groove 45. The fermentation tank body 1 is equipped with a blower 5. The output end of the blower 5 is connected to the internal ventilation groove 45. The bottom end of the built-in rotating cylinder 43 is fixedly connected to a drive gear 44. The fermentation tank body 1 is equipped with a drive mechanism 7 near the drive gear 44. It should be noted that the input end of the blower 5 can be connected to the external environment through a pipe. When the blower 5 is turned on, the blower 5 can deliver oxygen from the external environment to the output end of the blower 5 through the input end. The output end of the blower 5 then delivers the oxygen to the internal ventilation groove 45 inside the built-in rotating cylinder 43, filling the internal ventilation groove 45 with oxygen. The internal ventilation groove 45 can then deliver the oxygen to the internal ventilation hole 46. It should be noted that the output end of the blower 5 should be connected to all the internal ventilation grooves 45 inside the built-in rotating cylinder 43 through a pipe. The specific connection method should be adapted by those skilled in the art according to the internal space of the fermentation tank body 1 to ensure smooth oxygen flow.

[0040] The drive mechanism 7 includes a first drive motor 71 and a second drive motor 73. The output end of the first drive motor 71 is engaged with a first gear ring 72 via a gear, and the output end of the second drive motor 73 is engaged with a second gear ring 74 via a gear. The sides of the first gear ring 72 and the second gear ring 74 respectively mesh with the corresponding drive gears 44. It should be noted that when the urban sludge is placed into the aerobic fermentation tank 2, oxygen needs to be introduced into the urban sludge. At this time, the positions of the internal vent 46 and the external vent 42 are offset. When the first drive motor 71 and the second drive motor 73 are turned on, the output end of the first drive motor 71 drives the first gear ring 72 via a gear, and the first gear ring 72 will drive the drive gear 44 meshing with the first gear ring 72. The output end of the second drive motor 73 drives the second gear ring 74 via a gear, and the second gear ring 74 will drive the second gear ring 74. The drive gear 44, which meshes with the second gear ring 74, rotates and drives the built-in rotating cylinder 43, causing it to rotate. The rotating cylinder 43 aligns the position of the internal vent 46 with the position of the external vent 42, connecting them. This allows oxygen from the internal vent 46 to be transported to the interior of the urban sludge in the aerobic fermentation tank 2 through the external vent 42, increasing the oxygen content of the urban sludge and ensuring the high-temperature aerobic fermentation reaction. When the high-temperature aerobic fermentation reaction is complete and oxygen is no longer needed, the first drive motor 71 and the second drive motor 73 can be turned on, causing the drive gear 44 to rotate and drive the built-in rotating cylinder 43, ensuring that the positions of the internal vent 46 and the external vent 42 are offset.

[0041] Additionally, it should be noted that, in order for the first gear ring 72 and the second gear ring 74 to drive all the drive gears 44, the drive gears 44 should be arranged in a circular pattern at the bottom of the lifting base plate 3. Figure 1 To be continued Figure 4 One of the drive gears 44 is located at the center of the lifting base plate 3. This drive gear 44 cannot be driven by the first gear ring 72 or the second gear ring 74. Therefore, a separate motor can be set to drive the drive gear 44, or the drive gear 44 can be removed. The specific adjustments can be made by those skilled in the art based on the area of ​​the lifting base plate 3 and the number of built-in rotating cylinders 43.

[0042] Example 3

[0043] like Figure 1 - Figure 9 As shown, the sensor module installed on the oxygenation mechanism 4 includes a humidity sensor, a temperature sensor, and a pH sensor. The sensor module collects real-time parameter data of the urban sludge in the aerobic fermentation tank 2, including humidity data, temperature data, and pH value data. It should be noted that the humidity sensor, temperature sensor, and pH sensor are all selected by those skilled in the art according to the specifications of the oxygenation mechanism 4 to ensure that the humidity sensor, temperature sensor, and pH sensor can accurately collect the humidity data, temperature data, and pH value data of the urban sludge. In addition, those skilled in the art can also add or remove new types of sensors, such as density sensors, as needed.

[0044] In addition, humidity sensors, temperature sensors, and pH sensors can also be installed on the top surface of the lifting base plate 3 to ensure that the humidity sensors, temperature sensors, and pH sensors can accurately collect humidity data, temperature data, and pH value data of urban sludge.

[0045] The fermentation tank body 1 is equipped with a control module. The control module trains a machine learning model based on real-time collected humidity data, temperature data and pH data to predict the amount of oxygen introduced into the aerobic fermentation tank 2 by the oxygenation mechanism 4.

[0046] The method for training a machine learning model to predict the amount of oxygen supplied from oxygenation mechanism 4 to aerobic fermentation tank 2 is as follows:

[0047] A historical training dataset is pre-collected, comprising N sets of training data, where N is a positive integer greater than 0. The number of N sets is adaptively selected by those skilled in the art based on the specific model training situation. Each set of training data includes feature data and label data. The feature data includes humidity data, temperature data, and pH value data, wherein:

[0048] Humidity data refers to the humidity value of the urban sludge in the aerobic fermentation tank 2 that the control module collects in real time through the humidity sensor when collecting each set of training data;

[0049] Temperature data refers to the temperature value of the urban sludge in the aerobic fermentation tank 2 that the control module collects in real time through the temperature sensor when collecting each set of training data;

[0050] pH data refers to the pH value of the urban sludge in the aerobic fermentation tank 2 that the control module collects in real time through the pH sensor when collecting each set of training data.

[0051] Label data refers to the amount of oxygen supplied by the oxygenation mechanism 4 to the aerobic fermentation tank 2 when collecting each set of training data, which is the oxygen flow rate generated by the blower 5 during operation.

[0052] The feature data in the training data is transformed into feature vectors. These feature vectors are then used as input to the machine learning model. The machine learning model outputs the oxygen quantity predicted for each set of training data. The oxygen quantity in the label data corresponding to each set of feature data is used as the prediction target. The training objective is to minimize the sum of all prediction accuracies. The formula for calculating prediction accuracy is: ai = (bi - ci). 2 Where ai is the prediction accuracy, bi is the predicted oxygen amount corresponding to the i-th group of feature data, and ci is the oxygen amount in the i-th label data. The machine learning model is trained until the sum of the prediction accuracies converges and training stops. It should be noted that the convergent label is adaptively selected by those skilled in the art based on the specific model training situation.

[0053] The control module collects real-time humidity, temperature, and pH data of the sludge through the sensor module. Based on the humidity, temperature, and pH data, it uses a machine learning model to predict the amount of oxygen supplied by the oxygenation mechanism 4 to the aerobic fermentation tank 2, ensuring that the amount of oxygen supplied by the oxygenation mechanism 4 to the aerobic fermentation tank 2 is always within the preset range, which greatly improves the efficiency and effect of the high-temperature aerobic fermentation reaction of urban sludge in the aerobic fermentation tank 2.

[0054] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
