DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1 - Fig. 9As shown, the present invention discloses a high-temperature aerobic fermentation tank for rapidly reducing urban sludge with high water content, including a fermentation tank body 1, on the top of which an aerobic fermentation tank 2 is provided. It should be noted that during the collection process, the urban sludge can be directly poured into the aerobic fermentation tank 2 for high-temperature aerobic fermentation. Urban sludge refers to sludge generated during the operation and maintenance of urban municipal facilities related to urban life and urban life activities. The sludge referred to in the present invention refers to sewage plant sludge, water supply plant sludge, drainage pipe sludge, and dredged sludge. A lifting bottom plate 3 is provided on the inner side of the aerobic fermentation tank 2. It should be noted that the urban sludge can be directly poured into the aerobic fermentation tank 2 for high-temperature aerobic fermentation. It is obvious that the lifting bottom plate 3 and the aerobic fermentation tank 2 together form an open cavity for placing urban sludge. When the urban sludge is subjected to high-temperature aerobic fermentation in the open cavity and reaches the treatment standard, the lifting bottom plate 3 can move upward inside the aerobic fermentation tank 2 to automatically discharge the urban sludge in the aerobic fermentation tank 2 from the inside of the aerobic fermentation tank 2, and in the process of the lifting bottom plate 3 moving upward, the waste gas contained in the urban sludge is directly discharged under the action of the extrusion force, thereby ensuring that the pollution of the treated urban sludge is greatly reduced. The oxygenating mechanism 4 introduces oxygen into the aerobic fermentation tank 2. It should be noted that when the urban sludge inside the aerobic fermentation tank 2 is subjected to high-temperature aerobic fermentation, the oxygenating mechanism 4 can continuously introduce oxygen into the aerobic fermentation tank 2 to ensure the oxygen content of the urban sludge inside the aerobic fermentation tank 2, promote the high-temperature aerobic fermentation of the urban sludge inside the aerobic fermentation tank 2, and improve 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 oxygenating mechanism 4, and the sensor module collects the urban sludge in the aerobic fermentation tank 2 in real time. The parameter data is obtained, and based on the parameter data, the amount of oxygen introduced into the aerobic fermentation tank 2 by the oxygenating mechanism 4 is controlled. It should be noted that the parameter data of the urban sludge in the aerobic fermentation tank 2 can be collected in real time by the arranged sensor module, and then the amount of oxygen introduced into the aerobic fermentation tank 2 by the oxygenating mechanism 4 is controlled 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, so that the urban sludge in the aerobic fermentation tank 2 is in an efficient aerobic fermentation state, which greatly improves the aerobic fermentation efficiency and aerobic fermentation effect of the urban sludge, and ensures the treatment effect of the urban sludge.

[0034] Example 2

[0035] like Figure 1-Figure 9As shown, a plurality of cylindrical holes are evenly opened on the surface of the lifting bottom plate 3, and a cylindrical sleeve 31 is arranged in each of the cylindrical holes. A leakage hole 32 is penetrated on 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. The filter screen is used to prevent sludge from entering the leakage hole 32 and causing blockage of the leakage hole 32. A liquid collecting box 33 is arranged at the bottom of the lifting bottom plate 3, and an output pipe 34 is fixedly connected to one side of the liquid collecting box 33. It should be noted that when the urban sludge with a high water content is put into the aerobic fermentation tank 2, the water in the urban sludge will flow downward under the action of gravity, and finally enter through the leakage hole 32 on the cylindrical sleeve 31. Into the liquid collecting box 33, which can quickly reduce the water content of urban sludge. It should also be noted that an activated carbon filter layer can be set inside the leakage hole 32, so that the liquid water passing through the leakage hole 32 can meet the discharge standard, and a water pump is set in the liquid collecting box 33. 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 adaptively selected by technical personnel in this field according to the specifications of the liquid collecting box 33 to ensure that the water pump can discharge the liquid water in the liquid collecting box 33 in time. The end of the output pipe 34 away from the liquid collecting box 33 is selected by technical personnel in this field according to needs.

[0036] The bottom edge of the lifting floor 3 is fixedly connected with a hydraulic cylinder 6, and the bottom end of the hydraulic cylinder 6 is connected to a limiting sleeve 11 through a hydraulic rod, and the limiting 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 the high-temperature aerobic fermentation, that is, when the urban sludge in the aerobic fermentation tank 2 has reached the treatment effect, the hydraulic cylinder 6 can be opened. Since the top of the hydraulic cylinder 6 is fixedly connected to the bottom edge of the lifting floor 3, and the limiting 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 be reacted to the limit sleeve 11 through the hydraulic rod. The lifting bottom plate 3 is placed on the position sleeve 11 to move the lifting bottom plate 3 upward along the side wall of the aerobic fermentation tank 2. In the process of the lifting bottom plate 3 moving upward, the waste gas contained in the urban sludge is directly discharged under the action of the extrusion force, ensuring that the pollution of the treated urban sludge is greatly reduced, and the lifting bottom plate 3 will also scrape the side wall of the aerobic fermentation tank 2 to ensure that the urban sludge is cleanly treated. It should also be noted that when the top surface of the lifting bottom 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 bottom plate 3 and the top surface of the port of the aerobic fermentation tank 2, which is convenient for workers to directly remove the urban sludge on the top surface of the lifting bottom plate 3.

[0037] The oxygenation mechanism 4 includes an external fixed cylinder 41, a cylindrical groove that fits with the external fixed cylinder 41 is opened at the center of the top surface of the cylindrical sleeve 31, and a plurality of external ventilation holes 42 are opened on the side surface of the external fixed cylinder 41. It should be noted that since a cylindrical groove that fits with the external fixed cylinder 41 is opened at the center of the top surface of the cylindrical sleeve 31, when the lifting base plate 3 drives the cylindrical sleeve 31 to move, the cylindrical sleeve 31 can slide freely along the side surface of the external fixed cylinder 41 to ensure 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 sludge on the side surface of the external fixed cylinder 41.

[0038] The internal part of the external fixed cylinder 41 is provided with an internal rotating cylinder 43, and a plurality of internal vent holes 46 are provided on the side surface of the internal rotating cylinder 43, and the internal vent holes 46 correspond to the external vent holes 42 one by one. It should be noted that since the internal vent holes 46 correspond to the external vent holes 42 one by one, when the positions of the internal vent holes 46 correspond to the positions of the external vent holes 42, the oxygen in the internal vent holes 46 can directly enter the external vent holes 42, and 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 internal rotating cylinder 43 can rotate freely inside the external fixed cylinder 41. The built-in rotating cylinder 43 can be rotated so that the position of the internal air vent 46 on the built-in rotating cylinder 43 is staggered with the position of the external air vent 42, so that the urban sludge in the aerobic fermentation tank 2 cannot enter the internal air vent 46 through the external air vent 42, causing the internal air vent 46 to be blocked. When the internal air vent 46 transports oxygen to the external air vent 42, the position of the internal air vent 46 corresponds to the position of the external air vent 42, that is, they are connected. The high-pressure oxygen can also prevent the urban sludge in the external air vent 42 from entering the internal air vent 46, causing the internal air vent 46 to be blocked.

[0039] An internal ventilation groove 45 is provided inside the built-in rotating cylinder 43, and a blower 5 is arranged inside the fermentation tank body 1. The output end of the blower 5 is connected to the internal ventilation groove 45. A driving gear 44 is fixedly connected to the bottom end of the built-in rotating cylinder 43. A driving mechanism 7 is arranged inside the fermentation tank body 1 near the driving gear 44. It should be noted that the input end of the blower 5 can be connected to the external environment through a pipeline. When the blower 5 is turned on, the blower 5 can transport oxygen in the external environment to the output end of the blower 5 through the input end, and the output end of the blower 5 then transports the oxygen to the internal ventilation groove 45 provided inside the built-in rotating cylinder 43, so that the internal ventilation groove 45 is filled with oxygen, and the internal ventilation groove 45 can transport oxygen to the internal vent 46. It should be noted that the output end of the blower 5 should be connected to the internal ventilation grooves 45 provided in all the built-in rotating cylinders 43 at the same time through a pipeline. The specific connection method is adaptively adjusted by technical personnel in this field according to the space conditions inside the fermentation tank body 1 to ensure smooth circulation of oxygen.

[0040] The driving mechanism 7 includes a first driving motor 71 and a second driving motor 73. The output end of the first driving motor 71 is meshed with a first gear ring 72 through a gear, and the output end of the second driving motor 73 is meshed with a second gear ring 74 through a gear. The side surfaces of the first gear ring 72 and the second gear ring 74 are respectively meshed with the corresponding driving gear 44. It should be noted that when the urban sludge is placed in the aerobic fermentation tank 2, oxygen needs to be introduced into the urban sludge. At this time, the position of the internal vent 46 and the position of the external vent 42 are staggered with each other. The first driving motor 71 and the second driving motor 73 are turned on. The output end of the first driving motor 71 drives the first gear ring 72 through the gear, and the first gear ring 72 drives the driving gear 44 meshed with the first gear ring 72. The output end of the second driving motor 73 drives the second gear ring 74 through the gear, and the second gear ring 74 drives The driving gear 44 meshing with the second gear ring 74 is driven, and the rotating driving gear 44 will drive the built-in rotating cylinder 43 to rotate the built-in rotating cylinder 43. The rotating built-in rotating cylinder 43 can make the position of the internal air vent 46 correspond to the position of the external air vent 42, and the internal air vent 46 is also connected with the external air vent 42. At this time, the oxygen in the internal air vent 46 can be transported to the inside of the urban sludge in the aerobic fermentation tank 2 through the external air vent 42, so as to increase the oxygen content of the urban sludge and ensure the high-temperature aerobic fermentation reaction of the urban sludge. When the high-temperature aerobic fermentation reaction of the urban sludge is completed and oxygen is not needed, the first driving motor 71 and the second driving motor 73 can also be turned on, so that the rotating driving gear 44 will drive the built-in rotating cylinder 43 to ensure that the position of the internal air vent 46 and the position of the external air vent 42 are staggered with each other.

[0041] It should also be noted that, in order for the first gear ring 72 and the second gear ring 74 to drive all the driving gears 44, the driving gears 44 should be distributed in a circular ring shape at the bottom of the lifting base plate 3. Figure 1 To Attachment Figure 4 One of the driving gears 44 is located at the center of the lifting base plate 3. The driving gear 44 cannot be driven by the first gear ring 72 or the second gear ring 74, so another motor can be provided to drive the driving gear 44, or the driving gear 44 can be removed. The specific adjustment is made adaptively by those skilled in the art according to the area of ​​the lifting base plate 3 and the number of built-in rotating cylinders 43.

[0042] Example 3

[0043] like Figure 1 - Fig. 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 parameter data of the urban sludge in the aerobic fermentation tank 2 in real time, including humidity data, temperature data, and pH value data. It should be noted that the humidity sensor, temperature sensor, and pH sensor are adaptively selected by technicians in this field 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, technicians in this field can also add or reduce new types of sensors as needed, such as density sensors.

[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, which trains a machine learning model for predicting the amount of oxygen introduced by the oxygenation mechanism 4 into the aerobic fermentation tank 2 based on the humidity data, temperature data and pH value data collected in real time;

[0046] The method of training a machine learning model to predict the amount of oxygen introduced by the oxygenation mechanism 4 into the aerobic fermentation tank 2 is:

[0047] A historical training data set is collected in advance. The historical training data set includes N groups of training data, where N is a positive integer greater than 0. The number of N is adaptively selected by a person skilled in the art according to a specific model training situation. Each group 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 collected in real time by the control module 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 collected in real time by the control module through the temperature sensor when collecting each set of training data;

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

[0051] The label data refers to the amount of oxygen introduced into the aerobic fermentation tank 2 by the oxygenation mechanism 4 when collecting each set of training data, that is, the oxygen flow value generated by the blower 5 during operation.

[0052] The feature data in the training data is converted into a feature vector, and the feature vector is used as the input of the machine learning model. The machine learning model uses the oxygen content predicted for each set of training data as the output, and the oxygen content in the label data corresponding to each set of feature data as the prediction target. The training target is minimized by the sum of all prediction accuracies. The calculation formula for prediction accuracy is: ai = (bi-ci) 2 , where ai is the prediction accuracy, bi is the predicted oxygen content corresponding to the i-th group of feature data, and ci is the oxygen content in the i-th label data. The machine learning model is trained until the sum of the prediction accuracies converges. It should be noted that the converged labels are adaptively selected by technicians in this field according to the specific model training situation.

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

[0054] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
