DETAILED DESCRIPTION

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The present invention provides a microbial fermentation device for sludge treatment, such as Figure 1-4 As shown, the microbial fermentation device for sludge treatment includes: a base frame 1, on which a fermentation tank 2 for fermentation microorganisms for sludge treatment is arranged, and the fermentation tank 2 is provided with an electric heating tube 3 for heating; a tank cover 4, which is arranged on the fermentation tank 2; a lifting mounting plate 5, which is fixedly mounted on the fermentation tank 2; a purification box 6 for treating fermentation waste gas, which is fixedly mounted on the mounting plate 5, and a plurality of filter plates 14 and a sterilizing lamp 15 are arranged in the purification box 6; an air outlet pipe 7, which is fixedly connected to the tank cover 4, and the air outlet end of the air outlet pipe 7 is fixedly connected to the air inlet end of the purification box 6; an exhaust pipe 8 for discharging purified waste gas, which is fixedly mounted on the air outlet end of the purification box 6; a discharge pipe 9, which is fixedly connected to the bottom of the fermentation tank 2; a stirring mechanism for stirring sludge, which is arranged on the tank cover 4.

[0022] It should be noted that in the process of sludge treatment, microbial fermentation technology is widely used because it can efficiently decompose organic matter in sludge into more stable and easier to handle substances. However, while this biochemical reaction brings about treatment effects, it is also accompanied by a problem that cannot be ignored-the generation of waste gas; when microorganisms decompose organic matter, they will perform respiration and other biochemical reactions, and these processes will release a large amount of waste gas. These waste gases mainly include harmful gases such as carbon dioxide, hydrogen sulfide, and methane. Among them, although carbon dioxide has a high content in the atmosphere, its large-scale emission will still lead to an intensification of the greenhouse effect; hydrogen sulfide has a strong irritating odor and toxicity, which is harmful to human health; and methane is a greenhouse gas, and its greenhouse effect potential far exceeds that of carbon dioxide. Taking the patent document with the authorization announcement number CN215365396U as an example, the patent provides a microbial fermentation device for sludge treatment. The equipment achieves effective decomposition of organic matter in sludge through specific fermentation technology, but it is insufficient in waste gas treatment. In actual applications, due to the lack of effective exhaust gas collection and treatment mechanisms in the equipment, or the treatment mechanisms are not advanced enough, these harmful exhaust gases are often directly discharged into the atmosphere without proper treatment; this untreated exhaust gas emission will bring serious environmental problems. First, it will aggravate environmental pollution, especially air pollution. Harmful gases such as hydrogen sulfide and methane will have a negative impact on the quality of the atmosphere, leading to a decline in air quality and affecting people’s living environment. Secondly, these harmful gases will pose a potential threat to human health. Living in such an environment for a long time, people may face a variety of health risks such as respiratory diseases and cardiovascular diseases; therefore, to address this problem, we need to develop a new type of microbial fermentation device for sludge treatment;

[0023] In this embodiment, the base frame 1 serves as the supporting structure of the entire device, ensuring the stability and safety of the fermentation tank 2. Through stable support, the device can operate stably in various environments, ensuring the continuity and reliability of the sludge treatment process; the fermentation tank 2 is the core part of sludge treatment and provides the necessary space for microbial fermentation; through specific fermentation technology, the organic matter in the sludge is decomposed by microorganisms into more stable and easier to handle substances. The setting of the electric heating tube 3 can adjust the temperature in the fermentation tank as needed, provide the best environmental conditions for microbial fermentation, and improve the treatment efficiency; the tank cover 4 seals the fermentation tank 2 to prevent the leakage of sludge and waste gas. At the same time, the outlet pipe 7 arranged on it guides the waste gas generated during the fermentation process to the purification box 6 for treatment, ensuring the effective collection and treatment of the waste gas; the design of the lifting mounting plate 5 enables the purification box 6 to adjust the height as needed, which is convenient for operation and maintenance. This flexibility enables the device to adapt to different work requirements and improves the practicality and convenience of the device; the purification box 6 is a key part of waste gas treatment. Several filter plates 14 and sterilization lamps 15 arranged inside work together to filter and sterilize the waste gas. The filter plate 14 can remove solid particles and harmful substances in the exhaust gas, while the sterilization lamp 15 can kill bacteria, viruses and other microorganisms in the exhaust gas, ensuring the safety and environmental protection of the exhaust gas emission; the exhaust pipe 7 guides the exhaust gas generated in the fermentation tank 2 into the purification box 6, ensuring that the exhaust gas can be effectively treated. Its fixed connection design ensures the stability and continuity of the airflow and improves the efficiency of exhaust gas treatment; the exhaust gas treated by the purification box 6 is discharged into the atmosphere through the exhaust pipe 8. Since the exhaust gas has been filtered and sterilized, its emission concentration and toxicity are greatly reduced, thereby reducing the threat to the environment and human health; the discharge pipe 9 is fixedly connected to the bottom of the fermentation tank 2 for discharging the treated sludge. This design makes the discharge of sludge more convenient and facilitates subsequent treatment or utilization; the stirring mechanism is arranged on the tank cover 4, and the sludge is stirred to prevent its precipitation and agglomeration, ensuring that the sludge can be fermented evenly and improve the treatment effect.

[0024] In a further preferred embodiment of the utility model, the stirring mechanism includes: a shaft 10 rotatably mounted on the tank cover 4, the bottom end of the shaft 10 extending into the fermentation tank 2; a stirring frame 11 fixed on the shaft 10; a motor 12 fixed on the top of the tank cover 4 for driving the shaft 10; a coupling 13 fixed on the output shaft of the motor 12, one end of the coupling 13 being fixedly connected to the top end of the shaft 10.

[0025] In the present embodiment, the shaft 10 is mounted on the tank cover 4 by rotation, and its bottom end extends into the fermentation tank 2. This design enables the shaft 10 to rotate freely under the support of the tank cover 4, thereby driving the turning frame 11 fixed on the shaft 10 to turn the sludge in the fermentation tank 2. The rotation of the shaft 10 not only ensures the uniformity of the turning, but also effectively prevents the sedimentation and agglomeration of the sludge. The turning frame 11 is fixed on the shaft 10 and rotates with the rotation of the shaft 10. The shape and structural design of the turning frame 11 can ensure that the sludge in the fermentation tank 2 is fully stirred during the rotation process to keep it in a uniform state. This design helps to improve the fermentation efficiency of the sludge and ensure that the organic matter can be fully decomposed. The motor 12 is fixed on the top of the tank cover 4 to provide power for the turning mechanism. The output shaft of the motor 12 is fixedly connected to the top of the shaft 10 through the coupling 13 to achieve the transmission of power. The selection and installation position of the motor 12 ensure that the stirring mechanism can operate stably and reliably, providing a strong guarantee for the stirring of the sludge. One end of the coupling 13 is fixedly connected to the output shaft of the motor 12, and the other end is fixedly connected to the top of the shaft 10. This design not only realizes the power transmission between the motor 12 and the shaft 10, but also can compensate for the offset and angular error between the two shafts to a certain extent, thereby improving the stability and reliability of the entire stirring mechanism.

[0026] In a further preferred embodiment of the present invention, a detachable box cover 16 is provided on the top of the purification box 6, and a handle for grasping is fixedly installed on the top of the box cover 16.

[0027] In this embodiment, the design of the detachable box cover 16 allows the user to easily open or close the purification box 6 when needed, which is convenient for internal cleaning, maintenance, and filter replacement. This is crucial to ensure the long-term stable operation of the purification box 6; the box cover 16 is opened or closed by grasping the handle.

[0028] In a further preferred embodiment of the utility model, an electric hydraulic rod 17 for regulating the lifting of the mounting plate 5 is symmetrically fixedly installed on the top of the base frame 1 , and the top of the output rod of the electric hydraulic rod 17 is fixedly connected to the mounting plate 5 .

[0029] In this embodiment, the lifting and lowering of the mounting plate 5 is adjusted by controlling the extension and retraction of the electric hydraulic rod 17, and the opening and closing of the tank cover 4 can also be controlled with less effort.

[0030] In a further preferred embodiment of the utility model, a plurality of support columns 18 are symmetrically fixedly installed on the top of the base frame 1, the top ends of the support columns 18 are fixedly connected to the bottom of the fermentation tank 2, and support legs are symmetrically fixedly installed on the bottom of the base frame 1.

[0031] In this embodiment, the support column 18 is provided to ensure the stable placement of the fermentation tank 2. By fixing the top of the support column 18 to the bottom of the fermentation tank 2, it can be ensured that the fermentation tank 2 will not shake or tilt during operation, thereby ensuring the stability and safety of the sludge treatment process.

[0032] In a further preferred embodiment of the utility model, a valve is provided on the discharge pipe 9, an automatic exhaust valve is provided on the air outlet pipe 7, and a medicine injection tube is fixedly installed on the tank cover 4.

[0033] In this embodiment, a valve is provided on the discharge pipe 9 to control the discharge of sludge. By adjusting the valve, the discharge speed and discharge amount of sludge can be accurately controlled to meet different treatment requirements. This design makes the discharge process of sludge more flexible and controllable, and improves the treatment efficiency. An automatic exhaust valve is installed on the outlet pipe 7 to automatically adjust the air pressure in the fermentation tank 2. As the fermentation process proceeds, a certain amount of gas may be generated in the fermentation tank 2. The automatic exhaust valve can be automatically opened or closed according to the change of the air pressure in the tank, ensuring that the air pressure in the tank is always kept within a safe range. This not only improves the safety of the equipment, but also helps to maintain the stability of the fermentation process.

[0034] In a further preferred embodiment of the present invention, a hook is fixedly mounted on one side of the box cover 16, and a buckle matched with the hook is provided on one side of the purification box 6.

[0035] In this embodiment, through the cooperation of simple buckles and hooks, the user can quickly fix or separate the box cover 16 from the purification box 6. The design of the buckles and hooks can provide a stable fixing force to ensure that the box cover 16 maintains a stable position on the purification box 6, preventing the box cover 16 from loosening or falling off due to vibration or other factors during the processing process.

[0036] In summary, the microbial fermentation device for sludge treatment provided by the technical solution achieves efficient treatment of sludge and effective treatment of waste gas, significantly reducing pollution to the environment and threats to human health. The design of this device fully considers the needs of environmental protection and human health, and has high practical value and social significance.
