Description

Technical Field

[0001] The utility model belongs to the technical field of anaerobic fermentation, in particular to an anaerobic fermentation device for treating feces and sewage in public toilets. Background Art

[0002] With the development of cities and the growth of population, the number of public toilets has continued to increase, and the treatment of public toilet sewage has become an important environmental issue. Traditional methods for treating public toilet sewage mainly include direct discharge, simple sedimentation and chemical treatment. However, these methods have many defects. Direct discharge will seriously pollute water, soil and air, posing a huge threat to the ecological environment and human health. Simple sedimentation treatment is often ineffective and cannot completely remove harmful substances and pathogens in sewage. Although chemical treatment methods can reduce the content of pollutants to a certain extent, they may introduce new chemicals, causing secondary pollution, and the treatment cost is high. Under the concept of sustainable development, anaerobic fermentation technology has gradually attracted attention because of its dual advantages of energy recovery and environmental protection. Anaerobic fermentation can convert organic matter in public toilet sewage into renewable energy such as methane, while reducing the content of organic matter and reducing pollution to the environment.

[0003] The existing anaerobic fermentation device for treating public toilet sewage has the following shortcomings: in order to ensure that the fermented material can ferment naturally and fully in the fermentation barrel, stirring the fermented material is a key operation link. However, in the existing devices, most of them use a motor to drive the stirring rod to rotate to stir the fermented material. This stirring method has significant defects, and its uniform stirring effect is relatively poor. Due to the limitations of the motion range and stirring method of the stirring rod, it can often only produce a strong stirring effect in a local area, resulting in uneven distribution of the fermented material in the fermentation barrel, excessive stirring in some areas, and insufficient stirring in other areas. What is more serious is that at the bottom of the fermentation barrel, it is very easy for the fermented material to accumulate. Due to the structure and rotation method of the stirring rod, it is difficult to reach all corners of the bottom of the barrel, so that the fermented material at the bottom cannot participate in the effective stirring process. These accumulated fermented materials cannot fully contact with the microorganisms, which not only affects the efficiency and quality of the fermentation, but may also lead to incomplete local fermentation. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides an anaerobic fermentation device for treating feces and sewage in public toilets, comprising a fermentation barrel, a servo motor mounted on the top of the fermentation barrel, and a uniform stirring structure located inside the fermentation barrel;

[0005] The uniform stirring structure includes a rotating wheel A fixedly connected to the output end of the servo motor and a rotating wheel B located below the rotating wheel A, and an engaging wheel located in the middle of the rotating wheel A and the rotating wheel B. The outer walls of the engaging wheels are respectively engaged with the bottom of the rotating wheel A and the top of the rotating wheel B. A connecting rod is fixedly connected to the center of the bottom of the rotating wheel A. Two groups of stirring plates with staggered distribution are fixedly installed on the outer wall of the connecting rod. Two groups of breaking up plates are fixedly connected to the bottom of the rotating wheel B.

[0006] Preferably, the bottom of one group of the stirring plates is in contact with the inner bottom wall of the fermentation tank and the other group of stirring plates is located directly above it.

[0007] Preferably, the two groups of the scattering plates are fixedly connected by a connecting strip and the inner walls of the scattering plates are provided with equidistantly distributed guide holes.

[0008] Preferably, the meshing wheel is rotatably connected to a cross bar at one side close to the inner wall of the fermentation barrel.

[0009] Preferably, a mounting block is fixedly connected to a side of the cross bar away from the meshing wheel, and the mounting block is fixedly mounted on the inner wall of the fermentation barrel.

[0010] Preferably, a feeding pipe is provided on the outer wall of the fermentation barrel and is connected thereto, and equidistantly distributed supporting legs are installed on the bottom of the fermentation barrel.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The utility model adopts the design of uniform stirring structure, so that when stirring is performed, the servo motor starts to rotate and drives the A rotating wheel and the connecting rod to rotate together. At this time, due to the meshing relationship between the A rotating wheel, the meshing wheel and the B rotating wheel, the A rotating wheel can drive the meshing wheel and the B rotating wheel to rotate synchronously. As they rotate, the stirring plate on the outer wall of the connecting rod and the breaking plate below the B rotating wheel also start to rotate at high speed, thereby comprehensively stirring the fermented material. More importantly, the rotation directions of the stirring plate and the breaking plate are opposite. This coaxial reverse rotation design greatly improves the uniformity of stirring. During the stirring process, the rotational forces in different directions interact with each other, so that the fermented material can be more fully and evenly mixed in the fermentation barrel, effectively avoiding the problem of insufficient local stirring. In addition, during this process, the bottom of one set of stirring plates is tightly attached to the inner wall of the fermentation barrel, significantly reducing the accumulation of fermented material at the bottom of the fermentation barrel. When the stirring plates rotate, the fermented material at the bottom can be continuously turned and lifted, so that it fully participates in the stirring process, thereby ensuring that the fermented material in the entire fermentation barrel can be evenly processed, further improving the efficiency and quality of fermentation.

[0019] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 5 As shown, the utility model provides an anaerobic fermentation device for treating feces and sewage in public toilets, comprising a fermentation barrel 1, a servo motor 2 mounted on the top of the fermentation barrel 1, and a uniform stirring structure 3 located inside the fermentation barrel 1;

[0021] The uniform stirring structure 3 includes an A rotating wheel 31 fixedly connected to the output end of the servo motor 2 and a B rotating wheel 32 located below the A rotating wheel 31, and an engaging wheel 33 located in the middle of the A rotating wheel 31 and the B rotating wheel 32. The outer wall of the engaging wheel 33 is respectively engaged with the bottom of the A rotating wheel 31 and the top of the B rotating wheel 32. A connecting rod 34 is fixedly connected to the center of the bottom of the A rotating wheel 31. Two groups of stirring plates 35 with staggered distribution are fixedly installed on the outer wall of the connecting rod 34. Two groups of breaking plates 36 are fixedly connected to the bottom of the B rotating wheel 32.

[0022] The above solution is adopted: through the design of the uniform stirring structure 3, when stirring, the servo motor 2 starts to rotate and drives the A rotating wheel 31 and the connecting rod 34 to rotate together. At this time, due to the meshing relationship between the A rotating wheel 31 and the meshing wheel 33 and the B rotating wheel 32, the A rotating wheel 31 can drive the meshing wheel 33 and the B rotating wheel 32 to rotate synchronously when rotating. As they rotate, the stirring plate 35 at the outer wall of the connecting rod 34 and the scattering plate 36 under the B rotating wheel 32 also start to rotate at high speed, thereby fully stirring the fermented material. What is particularly important is that the rotation directions of the stirring plate 35 and the scattering plate 36 are opposite. This coaxial anti-rotation The rotating design greatly increases the uniformity of stirring. During the stirring process, the rotational forces in different directions interact with each other, so that the fermented material can be mixed more fully and evenly in the fermentation barrel 1, effectively avoiding the problem of insufficient local stirring. In this process, the bottom of one group of stirring plates 35 fits tightly against the inner wall of the fermentation barrel 1, significantly reducing the accumulation of fermented material at the bottom of the fermentation barrel 1. When the stirring plate 35 rotates, the fermented material at the bottom can be continuously turned over and lifted up, so that it can fully participate in the stirring process, thereby ensuring that the fermented material in the entire fermentation barrel 1 can be evenly processed, further improving the efficiency and quality of fermentation.

[0023] like Figures 1 to 5 As shown, the bottom of one group of the stirring plates 35 is in contact with the inner bottom wall of the fermentation barrel 1 and the other group of stirring plates 35 is located directly above it. The two groups of the scattering plates 36 are fixedly connected by connecting strips 37 and the inner walls of the scattering plates 36 are provided with equidistantly distributed diversion holes.

[0024] The above solution is adopted: the two groups of scattering plates 36 are staggered and fixed with connecting strips 37, so that the two groups of scattering plates 36 are fixedly installed at the bottom of the B rotating wheel 32. When the B rotating wheel 32 rotates, the two groups of scattering plates 36 can be driven to rotate together.

[0025] like Figures 1 to 5 As shown, the meshing wheel 33 is rotatably connected to a cross bar 321 at a side close to the inner wall of the fermentation barrel 1 , and the cross bar 321 is fixedly connected to a mounting block 322 at a side away from the meshing wheel 33 , and the mounting block 322 is fixedly mounted on the inner wall of the fermentation barrel 1 .

[0026] According to the above solution, the meshing wheel 33 is fixedly supported by the cross bar 321 and the mounting block 322 and is mounted on the inner wall of the fermentation barrel 1 .

[0027] like Figures 1 to 5 As shown, a feeding pipe 11 is provided on the outer wall of the fermentation barrel 1 and is in communication therewith, and supporting legs 12 are installed at the bottom of the fermentation barrel 1 at equal intervals.

[0028] According to the above solution, the fermentation product can be added into the fermentation barrel 1 through the feeding pipe 11 , and a valve is provided on the inner wall of the feeding pipe 11 .

[0029] The working principle and use process of this utility model:

[0030] First, when stirring the fermented material, the servo motor 2 starts and drives the A rotating wheel 31 and the connecting rod 34 to start rotating at the same time. At this time, there is a close meshing relationship between the A rotating wheel 31 and the meshing wheel 33 and the B rotating wheel 32. Therefore, when the A rotating wheel 31 rotates, it can drive the meshing wheel 33 and the B rotating wheel 32 to rotate synchronously. As these three wheels rotate, the stirring plate 35 at the outer wall of the connecting rod 34 and the breaking plate 36 under the B rotating wheel 32 also quickly enter a high-speed rotation state, thereby stirring the fermented material in all directions. It is particularly worth mentioning that the rotation directions of the stirring plate 35 and the breaking plate 36 are opposite. This ingenious design of coaxial inversion has great advantages. It can significantly increase the uniformity of stirring. During the stirring process, Because the two components rotate in different directions, the rotational forces generated will interact with each other. This interaction enables the fermented material to be mixed more fully and evenly in the fermentation barrel 1, effectively avoiding the situation of insufficient local stirring. Moreover, during the entire stirring process, the bottom of one group of stirring plates 35 maintains a close fit with the inner wall of the fermentation barrel 1. This design can greatly reduce the accumulation of fermented material at the bottom of the fermentation barrel 1. When the stirring plate 35 rotates, it can continuously turn over and lift the fermented material at the bottom, allowing these fermented materials to fully participate in the stirring. In this way, it is ensured that the fermented material in the entire fermentation barrel 1 can be evenly processed, further improving the efficiency and quality of fermentation, and providing a strong guarantee for the smooth progress of fermentation work.
