Description

Technical Field

[0001] This utility model relates to the field of livestock and poultry manure fermentation technology, specifically a fully enclosed anaerobic device for livestock and poultry manure fermentation. Background Technology

[0002] Livestock and poultry manure fermentation is a process that converts livestock and poultry manure into fertilizer or energy. In the process of livestock and poultry manure fermentation, anaerobic fermentation equipment is required. Anaerobic fermentation, as the name suggests, is the process by which microorganisms convert external substances into other substances through their own metabolism in the absence of oxygen.

[0003] For example, the utility model application with application number CN201921900140.9 discloses an anaerobic fermenter. Anaerobic fermenters similar to the above application still have the following shortcomings: the fermentation liquid settles at the bottom of the inner tank, resulting in insufficient fermentation.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a fully enclosed anaerobic device for the fermentation of livestock and poultry manure. Utility Model Content

[0005] The purpose of this invention is to provide a fully enclosed anaerobic device for the fermentation of livestock and poultry manure, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fully enclosed anaerobic device for fermenting livestock and poultry manure, comprising an anaerobic fermentation tank, a fermentation liquid circulation assembly, and a lower stirring assembly. The anaerobic fermentation tank includes an inner tank and a heating layer, with the heating layer located on the outer side of the inner tank. A partition is installed above the inner tank, and a feed pipe is fixed below the inner tank. Fermentation liquid circulation assemblies are installed on both sides of the outer surface of the anaerobic fermentation tank. Each fermentation liquid circulation assembly includes a suction pipe, a suction pump, a feeding pipe, a storage box, and nozzles. A suction pump is installed on the outer side of the suction pipe, and a feeding pipe is connected above the suction pump. A storage box is installed at the end of the feeding pipe, and the storage box is located on both sides of the partition. Nozzles are installed at equal intervals below the storage box. A lower stirring assembly and an upper stirring assembly are installed at the lower and upper sides of the inner tank, respectively.

[0007] Furthermore, the anaerobic fermenter also includes a vacuum insulation layer and an explosion-proof shell. The outer side of the heating layer is provided with a vacuum insulation layer, and the outer side of the vacuum insulation layer is equipped with an explosion-proof shell.

[0008] Furthermore, an upper cover is installed on the outer side of the partition, and a feed pipe and a safety valve are installed in the middle of the partition and the upper cover.

[0009] Furthermore, a filter screen is fixed at the inlet of the suction pipe, and the suction pipe penetrates the inner tank, the heating layer, the vacuum insulation layer, and the explosion-proof shell.

[0010] Furthermore, the lower stirring assembly includes a lower rotating shaft, a first stirring blade, a second stirring blade, and a drive motor. The lower rotating shaft is rotatably connected to the inner tank, and two sets of first stirring blades and two sets of second stirring blades are arranged on the outer side of the lower rotating shaft. The first stirring blades and the second stirring blades are staggered, and a drive motor is installed at one end of the outer side of the lower rotating shaft.

[0011] Furthermore, the upper stirring assembly includes a rotary motor, an upper rotating shaft, and a stirring shaft. The rotary motor is mounted on a partition plate, and the upper rotating shaft is provided on the lower side of the rotary motor. The stirring shaft is fixed on the lower outer side of the upper rotating shaft, and there are two sets of the upper rotating shaft and the stirring shaft, which are staggered between the two sets of stirring shafts.

[0012] This invention provides a fully enclosed anaerobic device for the fermentation of livestock and poultry manure, which has the following beneficial effects:

[0013] This invention is equipped with a fermentation liquid circulation component. The fermentation liquid at the bottom of the anaerobic fermenter is easily drawn into the feeding pipe and sent into the storage box at the top through the suction pipe and suction pump. The fermentation liquid can be sprayed into the inner tank through the evenly distributed nozzles at the bottom of the storage box, so that the livestock and poultry manure and fermentation liquid are fully mixed, and the fermentation liquid is prevented from settling at the bottom of the inner tank, which would result in incomplete fermentation.

[0014] This invention is equipped with a lower stirring assembly and an upper stirring assembly. The two sets of staggered stirring shafts can perform preliminary stirring and mixing of the upper part of the inner tank. The rotation of the first stirring blade and the second stirring blade can stir the livestock and poultry manure inside the inner tank to the upper side, reducing the occurrence of sedimentation and stratification. Furthermore, the staggered distribution of the first stirring blade and the second stirring blade can ensure more thorough stirring. During the fermentation process, the feed pipe and the discharge pipe remain closed, which is conducive to fully enclosed anaerobic fermentation. Attached Figure Description

The anaerobic fermentation tank 1 also includes a vacuum insulation layer 103 and an explosion-proof shell 104. The vacuum insulation layer 103 is disposed on the outer side of the heating layer 102, and the explosion-proof shell 104 is installed on the outer side of the vacuum insulation layer 103. A partition 2 is installed above the inner tank 101, and a partition plate is installed below the inner tank 101. The anaerobic fermenter 1 is equipped with a feed pipe 3 and a cover 4 on the upper outer side of the partition 2. The feed pipe 6 and safety valve 5 are installed in the middle of the partition 2 and the cover 4. The heating layer 102 has a built-in heating wire that can be energized for heating.

The explosion-proof shell 104 can strengthen the structural strength and play a role in heat insulation and heat preservation. During the fermentation process, the feed pipe 6 and the feed pipe 3 are kept closed, which is conducive to fully enclosed anaerobic fermentation.

[0022] like Figures 1-2As shown, fermentation broth circulation components 7 are installed on both sides of the exterior of the anaerobic fermenter 1. Each fermentation broth circulation component 7 includes a suction pipe 701, a suction pump 702, a feeding pipe 703, a storage box 704, and nozzles 705. The suction pump 702 is installed on the outside of the suction pipe 701, and the feeding pipe 703 is connected above the suction pump 702. The storage box 704 is installed at the end of the feeding pipe 703, and it is located on both sides of the partition 2. Nozzles 705 are installed at equal intervals below the storage box 704. A filter screen is fixed at the inlet of the suction pipe 701, and the suction pipe 701 penetrates the inner tank 1. 01. Heating layer 102, vacuum insulation layer 103, and explosion-proof shell 104; The fermentation liquid at the bottom of the anaerobic fermenter 1 is easily drawn into the feeding pipe 703 and sent into the storage box 704 above through the suction pipe 701 and the suction pump 702. The liquid can be sprayed into the inner tank 101 through the evenly distributed nozzles 705 below the storage box 704, so that the livestock and poultry manure and fermentation liquid are fully mixed, and the fermentation liquid is prevented from settling at the bottom of the inner tank 101, resulting in insufficient fermentation. The feed inlet of the suction pipe 701 is fixed with a filter screen to prevent solid materials from entering.

[0023] like Figure 1 and Figure 2 As shown, a lower stirring assembly 8 and an upper stirring assembly 9 are respectively installed at the lower and upper parts of the inner tank 101. The lower stirring assembly 8 includes a lower rotating shaft 801, a first stirring blade 802, a second stirring blade 803, and a drive motor 804. The lower rotating shaft 801 is rotatably connected to the inner tank 101, and two sets of first stirring blades 802 and two sets of second stirring blades 803 are arranged on the outer side of the lower rotating shaft 801. The first stirring blades 802 and the second stirring blades 803 are staggered, and the drive motor 804 is installed at one end of the lower rotating shaft 801. The drive motor 804 and the lower rotating shaft 801 facilitate the rotation of the first stirring blades 802 and the second stirring blades 803, thereby stirring the livestock and poultry manure inside the inner tank 101 to the upper side, reducing sedimentation and stratification. The staggered distribution of the first stirring blades 802 and the second stirring blades 803 ensures more thorough stirring.

[0024] like Figure 1 and Figure 4 As shown, the upper stirring assembly 9 includes a rotary motor 901, an upper rotating shaft 902, and a stirring shaft 903. The rotary motor 901 is mounted on the partition plate 2, and the upper rotating shaft 902 is provided on the lower side of the rotary motor 901. The stirring shaft 903 is fixed on the lower outer side of the upper rotating shaft 902, and there are two sets of upper rotating shaft 902 and stirring shaft 903, which are staggered. The rotary motor 901 and the upper rotating shaft 902 facilitate the rotation of the stirring shaft 903, and the two sets of staggered stirring shafts 903 can perform preliminary stirring and mixing of the upper part of the inner tank 101.

[0025] In summary, as Figures 1-4 As shown, the fully enclosed anaerobic device for fermenting livestock and poultry manure first feeds the livestock and poultry manure into the inner tank 101 through the feed pipe 6. At this time, the rotation of the stirring shaft 903 is driven by the rotary motor 901 and the upper rotating shaft 902. The two sets of staggered stirring shafts 903 can perform preliminary stirring and mixing of the upper part of the inner tank 101. The rotation of the first stirring blade 802 and the second stirring blade 803 is driven by the drive motor 804 and the lower rotating shaft 801, thereby stirring the livestock and poultry manure inside the inner tank 101 to the upper side, reducing the occurrence of sedimentation and stratification. Furthermore, the staggered distribution of the first stirring blade 802 and the second stirring blade 803 can make the stirring more thorough.

[0026] Then, the fermentation liquid at the bottom of the anaerobic fermenter 1 can be drawn into the feeding pipe 703 through the suction pipe 701 and the suction pump 702, and finally sent into the storage box 704 at the top. Then, the fermentation liquid is sprayed into the inner tank 101 through the evenly distributed nozzles 705 below the storage box 704, so that the livestock and poultry manure and fermentation liquid are fully mixed. During use, the heating layer 102 has a built-in heating wire that can be energized to heat the inner tank 101, so that the fermentation temperature can be maintained inside the inner tank 101. At the same time, the vacuum insulation layer 103 can play a role in heat insulation and heat preservation. During the fermentation process, the feed pipe 6 and the discharge pipe 3 are kept closed. In this way, the use process of the fully enclosed anaerobic device for livestock and poultry manure fermentation is completed.
