Description
Technical Field
[0001] This utility model relates to the field of municipal environmental protection engineering technology; more specifically, it relates to a biogas fermentation device for municipal environmental protection engineering. Background Technology
[0002] Municipal environmental protection engineering refers to a series of engineering measures and technologies adopted during urban construction and management to improve and protect the ecological environment and enhance the quality of the urban environment. A biogas fermentation device is a device used to convert organic waste (such as agricultural waste, animal manure, and kitchen waste) into biogas (mainly composed of methane and carbon dioxide) through an anaerobic fermentation process. Biogas is not only a renewable energy source but also effectively reduces greenhouse gas emissions and mitigates negative environmental impacts.
[0003] Currently, existing biogas fermentation devices for municipal environmental protection projects suffer from several drawbacks. Firstly, they typically mix organic waste with water and feed it into the device, then wait for fermentation to produce biogas. However, since organic waste is generally solid, fermentation may be slow or incomplete, affecting the biogas fermentation process. Secondly, some existing devices are not convenient for discharging waste, often requiring specialized tools for extraction, making the waste disposal process time-consuming and labor-intensive. Therefore, there is an urgent need for a biogas fermentation device for municipal environmental protection projects to address these issues. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a biogas fermentation device for municipal environmental protection engineering, so as to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a biogas fermentation device for municipal environmental protection engineering, comprising:
[0006] The fermentation structure includes a fermentation tank, a support frame, a baffle plate, a motor, a rotating column, crushing blades, a connecting column, stirring blades, and a sludge discharge base. The baffle plate and the connecting column are provided in two sets, and the crushing blades and the stirring blades are provided in multiple sets.
[0007] The sewage discharge structure includes a sewage discharge cylinder, a turntable, a movable column, a blocking cover, a fixed block, and a limiting block. Two sets of movable columns, fixed blocks, and limiting blocks are provided, and the upper end of the sewage discharge cylinder is fixedly connected to the outer surface of the lower end of the sewage discharge base.
[0008] Preferably, the upper surface of the fermenter is provided with a feed inlet, the upper end of the support frame is fixedly connected to the outer surface of the fermenter, two sets of the baffles are respectively fixedly connected to both sides of the inner surface of the fermenter, and the motor is installed on the upper surface of the fermenter. The support frame can support the entire equipment, thereby improving the stability of the equipment during use.
[0009] Preferably, the upper end of the rotating column is fixedly connected to the output end of the motor, and the various crushing blades are respectively fixedly connected to both sides of the outer surface of the lower middle position of the rotating column. The two sets of connecting columns are respectively fixedly connected to the two ends of the outer surface of the rotating column. An external power supply can provide power to the motor, and after the motor is started, it can drive the rotating column and the multiple sets of crushing blades to rotate, thereby crushing the organic waste.
[0010] Preferably, the various stirring blades are fixedly connected to the outer surfaces of the two sets of connecting columns, and the sewage discharge base is fixedly connected to the lower end of the fermentation tank. The sewage discharge base is funnel-shaped. When the rotating column rotates, it will drive the two sets of connecting columns and the various stirring blades to rotate synchronously, so that the stirring blades can stir the organic waste.
[0011] Preferably, the surface of one side of the turntable is attached to the surface of the other end of the sewage pipe, and the inside of the turntable surface is provided with a moving groove, and there are two sets of moving grooves. The two sets of moving columns are respectively inserted into the two sets of moving grooves. The surface of the other side of the turntable is provided with a handle, so that the user can rotate the turntable more effortlessly.
[0012] Preferably, one side of the blocking cover is fixedly connected to one side of the sewage discharge cylinder. Two sets of fixing blocks are respectively inserted into the two ends inside the middle position of the blocking cover, and one side of the two sets of fixing blocks is fixedly connected to one end of the two sets of moving columns. The one side of the two sets of fixing blocks is attached to the inner surface of the sewage discharge cylinder. Two sets of limiting blocks are respectively fixedly connected to both sides of the outer surface of the blocking cover. A limiting groove is opened inside the lower end of the sewage discharge cylinder, and the size of the limiting groove is adapted to the size of the two sets of limiting blocks. The setting of two sets of blocking covers can prevent the blocking cover from rotating, and the two sets of fixing blocks can fix the blocking cover and the sewage discharge cylinder.
[0013] The technical effects and advantages of this utility model are as follows: This utility model provides power to the motor through an external power source. After the motor is started, it can drive the rotating column and various crushing blades to rotate, and can also drive two sets of connecting columns and multiple sets of stirring blades to rotate at the same time. When the multiple sets of crushing blades rotate, they can crush the organic waste, and when the multiple sets of stirring blades rotate, they can stir the organic waste and water. This design can make the reaction between water and organic waste more complete, thereby improving the fermentation speed of biogas.
[0014] This invention uses a rotating turntable to move two sets of movable columns, bringing them closer together. This, in turn, moves two sets of fixed blocks closer together, allowing the two sets of fixed blocks to be fully inserted into the interior of the blocking cover. This causes one side of the fixed blocks to detach from the inner surface of the drain pipe, at which point the blocking cover can be removed, allowing the waste inside the fermenter to be discharged through the drain pipe. This design makes waste discharge more time-saving and labor-saving, eliminating the need for specialized tools for extraction. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The biogas fermentation device for municipal environmental protection projects involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1
[0022] like Figures 1 to 3As shown, this utility model provides a biogas fermentation device for municipal environmental protection engineering, including: a fermentation structure 1, which includes a fermentation tank 11, a support frame 12, a baffle plate 13, a motor 14, a rotating column 15, crushing blades 16, a connecting column 17, stirring blades 18, and a sewage discharge base 19. Two sets of baffle plates 13 and connecting columns 17 are provided, and multiple sets of crushing blades 16 and stirring blades 18 are provided. A feed inlet is provided on the upper surface of the fermentation tank 11. The upper end of the support frame 12 is fixedly connected to the outer surface of the fermentation tank 11. Two sets of baffle plates 13 are respectively fixedly connected to both sides of the inner surface of the fermentation tank 11. The motor 14 is mounted on... Mounted on the upper surface of fermentation tank 11, the upper end of rotating column 15 is fixedly connected to the output end of motor 14. Various crushing blades 16 are fixedly connected to both sides of the outer surface of the lower middle position of rotating column 15. Two sets of connecting columns 17 are fixedly connected to both ends of the outer surface of rotating column 15. Various stirring blades 18 are fixedly connected to the outer surfaces of the two sets of connecting columns 17. A sludge discharge base 19 is fixedly connected to the lower end of fermentation tank 11, and the sludge discharge base 19 is funnel-shaped. During operation, personnel can add organic waste and water into the fermentation tank 11 through the feed inlet at the upper end of fermentation tank 11, and then discharge the waste through an external connection. The power source provides power to the motor 14. When the motor 14 is started, it drives the rotating column 15 to rotate inside the fermenter 11, and also drives multiple sets of crushing blades 16 to rotate. The rotating blades 16 crush the organic waste inside the fermenter 11, thus preventing its excessive volume from reducing the reaction rate. Furthermore, the rotating column 15 drives the two connecting columns 17 and multiple sets of stirring blades 18 to rotate synchronously. The rotating blades 18 thoroughly mix the organic waste and water inside the fermenter 11, promoting the uniform distribution of organic matter and the activity of microorganisms. The arrangement of two sets of stirring blades 18 can change the flow direction of the liquid, promote uniform liquid distribution, reduce dead zones, and effectively improve the mixing effect of materials. During the stirring process, vortices are easily formed, and the arrangement of two sets of stirring blades 18 can effectively reduce the generation of vortices, ensuring uniform mixing of materials in the entire fermentation tank 11. In addition, the two sets of stirring blades 18 can increase the shear strength of the mixture of organic waste and water, promote more complete interaction between organic waste of different viscosities and water, and improve mixing efficiency. Finally, the waste after sedimentation can be discharged outward through the sewage discharge base 19. Example 2
[0023] like Figures 4 to 5As shown, this embodiment also proposes a sewage discharge structure 2, which includes a sewage discharge cylinder 21, a turntable 22, a movable column 23, a blocking cover 24, a fixing block 25, and a limiting block 26. Two sets of movable columns 23, fixing blocks 25, and limiting blocks 26 are provided. The upper end of the sewage discharge cylinder 21 is fixedly connected to the outer surface of the lower end of the sewage discharge base 19. One side of the turntable 22 is attached to the surface of the other end of the sewage discharge cylinder 21. A movable groove is formed inside the surface of the turntable 22, and two sets of movable grooves are formed. Two sets of movable columns 23 are respectively inserted into the two sets of movable grooves. One side of the blocking cover 24 is fixedly connected to one side of the sewage discharge cylinder 21. Two sets of fixing blocks 25 are respectively inserted into the two ends inside the middle position of the blocking cover 24. One side of each of the two sets of fixing blocks 25 is fixedly connected to one end of each of the two sets of movable columns 23. The surfaces of the two sets of fixing blocks 25 are attached to the inner surface of the sewage discharge cylinder 21. Limiting blocks 26 are fixedly connected to both sides of the outer surface of the blocking cover 24. A limiting groove is opened inside the lower end of the sewage discharge cylinder 21, and the size of the limiting groove is adapted to the size of the two sets of limiting blocks 26. A handle is provided on the other side of the turntable 22, so that the operator can rotate the turntable 22 more easily. When the turntable 22 rotates, it can drive the two sets of moving columns 23 to move inside the two sets of moving grooves and move closer to each other, thereby driving the two sets of fixing blocks 25 to move closer to each other inside the blocking cover 24, so that the surface of one side of the two sets of fixing blocks 25 is separated from the inner surface of the sewage discharge cylinder 21. At this time, the moving columns 23 can be removed from the inside of the sewage discharge cylinder 21, so that the waste inside the fermentation tank 11 can be discharged out through the sewage discharge cylinder 21. The two sets of limiting blocks 26 can be engaged with the limiting groove opened inside the sewage discharge cylinder 21, thereby preventing the blocking cover 24 from rotating inside the sewage discharge cylinder 21.
[0024] Working principle: When using the equipment, organic waste and water are first added into the fermentation tank 11 through the feed port on the upper surface of the fermentation tank 11. Then, the motor 14 is powered by an external power source. The motor 14 is then started to drive the rotating column 15, the connecting column 17, the multiple sets of crushing blades 16 and the stirring blades 18 to rotate inside the fermentation tank 11. The multiple sets of crushing blades 16 are driven to rotate, crushing the organic waste inside the fermentation tank 11. The multiple sets of stirring blades 18 can fully mix the organic waste and water inside the fermentation tank 11 when they rotate.
[0025] When it is necessary to discharge the waste inside the fermentation tank 11, first rotate the turntable 22 to drive the two sets of moving columns 23 to move closer to each other, thereby driving the two sets of fixed blocks 25 to move closer to each other inside the blocking cover 24, so that the surface of one side of the two sets of fixed blocks 25 is separated from the inner surface of the drain pipe 21. Then, the blocking cover 24 can be removed to discharge the waste inside the fermentation tank 11 through the drain pipe 21. The above is the entire working principle of this utility model.
[0026] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
