The device is equipped with a fixing mechanism, which can fix and support the connected excretion pipe, so that the excretion pipe will not be unable to discharge excrement and sewage into the fermentation tank during the process of transporting excrement and sewage, thereby causing pollution to the environment and waste of resources; since the existing fermentation tank only relies on natural ventilation to discharge the fermentation harmful gases in the tank during ventilation, the overall discharge cycle is long and the effect is poor, which easily causes excessive accumulation of fermentation harmful gases in the tank. At the same time, poor ventilation will lead to the emergence of anaerobic conditions, thereby inhibiting the activity of beneficial microorganisms and affecting the degradation and conversion efficiency of organic matter. However, the above-mentioned device has not made improvements to this problem, and the overall practical effect is poor. Utility Model Content

[0021] 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.

[0022] When implementing: Figure 1-5As shown, an ecological toilet fermentation tank comprises a fermentation tank body 1 and a protective cover 2: the top outer wall of the fermentation tank body 1 is provided with a protective cover 2, the interior of the fermentation tank body 1 is provided with a separation processing mechanism 3, the top of the fermentation tank body 1 is provided with a ventilation control mechanism 4, the side of the fermentation tank body 1 is provided with an accelerated fermentation mechanism 5, the separation processing mechanism 3 comprises a supporting bottom plate 31, a first dividing plate 32, a second dividing plate 33, a first guide pipe 34 and a second guide pipe 35, the side inner wall of the fermentation tank body 1 near the bottom is provided with a supporting bottom plate 31, the top outer wall of the supporting bottom plate 31 is provided with a first dividing plate 32 and a second dividing plate 33, the side outer wall of the first dividing plate 32 is connected and installed with a first guide pipe 34, the side outer wall of the second dividing plate 33 is connected and installed with a second guide pipe 35, the first dividing plate 32 and the second dividing plate 33 divide the interior of the fermentation tank body 1 into three different placement spaces, and the liquid inlet height of the first guide pipe 34 is lower than the liquid inlet height of the second guide pipe 35; as shown in the attached manual Figure 1 As shown, a feed pipe is installed on the side outer wall of the fermentation tank body 1 near the top position. During the specific installation, the channel can be connected through this feed pipe. Here, the first partition plate 32 and the second partition plate 33 are jointly arranged to divide the fermentation tank body 1 into three different placement intervals: sedimentation tank, fermentation tank and clear water tank, so as to facilitate the zoning treatment of excreta, and the first guide pipe 34 and the second guide pipe 35 are set to be channels for transferring excreta between adjacent intervals.

[0023] The ventilation control mechanism 4 includes an axial flow fan 41, a through slot 42 and a positioning card slot 43. The top outer wall of the protective cover 2 is connected to the axial flow fan 41, and the top outer wall of the protective cover 2 is connected to the through slot 42. The top outer wall of the protective cover 2 located at the through slot 42 is symmetrically provided with two groups of positioning card slots 43. The interior of the through slot 42 is provided with a mounting frame 44, and the interior of the mounting frame 44 is provided with a protective net 45. The outer walls on both sides of the mounting frame 44 are symmetrically provided with two groups of positioning blocks 46. The positioning blocks 46 and the positioning slots 43 are engaged with each other, and the top of the positioning blocks 46 is provided with a protective net 45. A first thread groove 47 is provided through the outer wall, and a second thread groove 48 is provided on the outer wall of the top end of the protective cover 2 located at the position of the positioning slot 43. The first thread groove 47 and the second thread groove 48 are threadedly installed with the locking bolt 49. When it is necessary to accelerate the air flow speed inside the fermentation tank body 1 in order to accelerate the discharge of harmful fermentation gases inside the fermentation tank body 1, the axial flow fan 41 needs to be turned on first. It is noted here that the air outlet end of the axial flow fan 41 is facing the temporal part of the fermentation tank body 1. Then, when the axial flow fan 41 is turned on, the wind force it generates will automatically accelerate the air flow speed inside the fermentation tank body 1. The gas flow speed of the fermentation tank body 1 is increased, and then through the setting of the through groove 42, the gas inside the fermentation tank body 1 will be accelerated to pass through the through groove 42 and discharged to the outside of the fermentation tank body 1. The setting of the protective net 45 here not only does not affect the normal discharge of gas, but also prevents external debris from entering the fermentation tank body 1. When the protective net 45 needs to be removed for cleaning, the locking bolt 49 needs to be completely unscrewed from the inside of the first threaded groove 47, and then the positioning block 46 changes from the locked state to the active state, and then the positioning block 46 is directly installed together with the outer frame 44. And take it out from the inside of the through slot 42, and then the installation outer frame 44 will be removed together with the protective net 45. After cleaning, when the protective net 45 needs to be reinstalled on the top of the device, you only need to adjust the installation outer frame 44 to the appropriate position and push it into the inside of the positioning slot 43 together with the positioning block 46. When the positioning block 46 moves to the bottom end of the positioning slot 43, the first thread groove 47 and the second thread groove 48 are in a corresponding fitting state. Then directly pass the locking bolt 49 through the first thread groove 47 and screw it to the bottom end of the second thread groove 48 to complete the installation.

[0024] The accelerated fermentation mechanism 5 includes an electric heating plate 51, a temperature equalizing plate 52 and a positioning box 53. The bottom inner wall of the fermentation tank body 1 is provided with an electric heating plate 51, and the top outer wall of the electric heating plate 51 is fitted with a temperature equalizing plate 52. The top outer wall of the temperature equalizing plate 52 is fitted with the bottom outer wall of the supporting bottom plate 31. The side outer wall of the fermentation tank body 1 at the bottom position is provided with a positioning box 53, and the bottom inner wall of the positioning box 53 is provided with a power supply 54 and a controller 55. The top outer wall of the positioning box 53 is provided with a temperature monitoring sensor 56, and a temperature conducting rod 57 is connected between the temperature monitoring sensor 56 and the side outer wall of the fermentation tank body 1. It is noted here that the monitoring range of the temperature monitoring sensor 56 needs to be set in advance according to the fermentation temperature requirement of the excrement. When the fermentation speed of the excrement needs to be accelerated in low temperature weather, the temperature monitoring sensor 56 needs to be turned on first. Here, the temperature conducting rod 57 is turned on. The arrangement facilitates the real-time transmission of the outer wall temperature of the fermentation tank body 1 to the temperature monitoring sensor 56. Once the outer wall temperature of the fermentation tank body 1 is lower than the monitoring range of the temperature monitoring sensor 56, the temperature monitoring sensor 56 will automatically transmit the information to the controller 55. After the controller 55 is turned on, it will automatically control the power supply 54 to start powering the electric heating plate 51. Then, the electric heating plate 51 automatically generates heat when powered on and heats the temperature equalizing plate 52 through heat transfer, thereby heating the excrement inside the fermentation tank body 1. Once the outer wall temperature of the fermentation tank body 1 reaches or exceeds the monitoring range of the temperature monitoring sensor 56, the temperature monitoring sensor 56 will also transmit the information to the controller 55. At this time, the controller 55 automatically controls the power supply 54 to stop powering the electric heating plate 51, thereby achieving the temperature control effect through the above working process.

[0025] When using this utility model, as shown in the attached instructions Figure 1 As shown, a feed pipe is installed on the side outer wall of the fermentation tank body 1 near the top position. During the specific installation, the feed pipe can be used to connect the channel. Here, the first partition plate 32 and the second partition plate 33 are jointly set to divide the fermentation tank body 1 into three different placement areas: the sedimentation tank, the fermentation tank and the clear water tank, so as to facilitate the treatment of the excreta in different areas. The first guide pipe 34 and the second guide pipe 35 are set to be channels for transferring excreta between adjacent areas.

[0026] When it is necessary to accelerate the air flow speed inside the fermentation tank body 1 in order to accelerate the discharge of harmful fermentation gases inside the fermentation tank body 1, it is necessary to first turn on the axial flow fan 41. It is noted here that the air outlet end of the axial flow fan 41 is facing the temporal part of the fermentation tank body 1. Then, when the axial flow fan 41 is turned on, the wind force it generates will automatically accelerate the gas flow speed inside the fermentation tank body 1. Then, through the setting of the through groove 42, the gas inside the fermentation tank body 1 will be accelerated to pass through the through groove 42 and be discharged to the outside of the fermentation tank body 1. The setting of the protective net 45 here not only does not affect the normal discharge of gas, but also prevents external debris from entering the interior of the fermentation tank body 1. When it is necessary to remove the protective net 45 for cleaning, it is necessary to first tighten the locking bolt 4 9 is completely unscrewed from the inside of the first thread groove 47, and the positioning block 46 is changed from the locked state to the active state, and then the positioning block 46 can be directly taken out from the inside of the through groove 42 together with the mounting outer frame 44, and then the mounting outer frame 44 is moved out and the protective net 45 is taken out together. When the cleaning is completed and the protective net 45 needs to be reinstalled on the top of the device, it is only necessary to adjust the mounting outer frame 44 to a suitable position and push it together with the positioning block 46 into the inside of the positioning slot 43. When the positioning block 46 moves to the bottom end of the positioning slot 43, the first thread groove 47 and the second thread groove 48 are in a corresponding fit state. Then, the locking bolt 49 is directly passed through the first thread groove 47 and screwed to the bottom end of the second thread groove 48 to complete the installation.

[0027] It should be noted that the monitoring range of the temperature monitoring sensor 56 needs to be set in advance according to the fermentation temperature requirement of the excrement. When the fermentation speed of the excrement needs to be accelerated in low temperature weather, the temperature monitoring sensor 56 needs to be turned on first. The setting of the temperature conducting rod 57 here facilitates the real-time transmission of the outer wall temperature of the fermentation tank body 1 to the temperature monitoring sensor 56. Once the outer wall temperature of the fermentation tank body 1 is lower than the monitoring range of the temperature monitoring sensor 56, the temperature monitoring sensor 56 will automatically transmit the information to the controller 55. Then, after the controller 55 is turned on, it will automatically control the power supply 54 to turn on the electric heating plate 51. Then, the electric heating plate 51 automatically generates heat when it is powered on and heats the temperature equalizing plate 52 through heat transfer, thereby heating the excrement inside the fermentation tank body 1. Once the outer wall temperature of the fermentation tank body 1 reaches or exceeds the monitoring range of the temperature monitoring sensor 56, the temperature monitoring sensor 56 will also transmit the information to the controller 55. At this time, the controller 55 automatically controls the power supply 54 to stop supplying power to the electric heating plate 51. In this way, the temperature control effect is achieved through the above working process.

[0028] It is noted here that the above-mentioned axial flow fan 41 can be powered by existing operating technical means, whether it is powered by a power supply unit or an external wire, which belongs to existing conventional operating technical means and will not be described in detail here.

[0029] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
