Description

Technical Field

[0001] The utility model relates to the technical field of microbial inoculant propagation, in particular to a microbial inoculant propagation device. Background Art

[0002] In the process of microbial inoculant propagation and cultivation, liquid medium or solid medium is generally used for cultivation. The liquid medium can provide sufficient nutrients and can be conveniently aerated and stirred, which is beneficial to the growth and reproduction of microorganisms.

[0003] In the prior art for the propagation and cultivation of microbial inoculants, generally, water at an appropriate temperature is first put into a barrel body, and then a certain proportion of brown sugar, inoculant, carrier and other culture media are put into the water and stirred. The stirring method is manual stirring. The manual stirring method is relatively slow. For different carriers, the dissolution speed in water and the required stirring force are also different. In the case of a large demand for the propagated bacterial fertilizer, the stirring efficiency is low, and the phenomenon of uneven stirring will also occur, affecting the propagation of the inoculant. There is also stirring by holding a hand-held electric stirrer. However, the electric stirrer is relatively heavy, so that the stirrer will shake and other dangerous situations will occur during the stirring process. Moreover, for the brown sugar, inoculant, carrier and other culture media added to the water, the proportion in the water is relatively small and it is not easy to be completely dispersed, affecting the uniform distribution in the water and being not conducive to the propagation of the inoculant. Content of the Utility Model

[0004] To solve the technical problems existing in the above background art, the utility model provides a microbial inoculant propagation device.

[0005] The technical solution of the utility model is as follows:

[0006] A microbial inoculant propagation device includes a barrel body and a stirrer arranged therein. The upper part of the barrel body is provided with a feed inlet. The stirrer includes a vertically arranged stirring shaft and a plurality of first stirring rods arranged thereon. It also includes a pre-stirring filter cylinder arranged in the upper part of the barrel body. The pre-stirring filter cylinder is arranged above the first stirring rods and includes an annular side plate and a bottom plate which are integrally formed and are both provided with leakage holes. The middle part of the bottom plate is rotatably connected to the stirring shaft. The upper part of the annular side plate is connected to the inner wall of the barrel body through a cross bar;

[0007] A plurality of second stirring rods are also arranged on the stirring shaft and are located in the pre-stirring filter cylinder. The second stirring rod located below is the bottom stirring rod, which is parallel to the bottom plate, and one end extends towards the annular side plate and does not interfere with the annular side plate;

[0008] The lengths of the plurality of second stirring rods decrease successively from bottom to top.

[0009] Inject water at a suitable temperature required for the microbial inoculant into the barrel body, with the water surface not higher than the upper end face of the pre-stirring filter cylinder and not lower than the lower end face of the pre-stirring filter cylinder. Then, put a certain proportion of brown sugar, inoculant, carrier, and other culture media into the pre-stirring filter cylinder. By starting the stirrer, use the second stirring rod to pre-stir the brown sugar, inoculant, carrier, and other culture media in the pre-stirring filter cylinder, so that the brown sugar, inoculant, carrier, and other culture media are evenly mixed in the water and flow out of the pre-stirring filter cylinder through the filter holes on the annular side plate and the bottom plate, avoiding the phenomenon that the brown sugar, inoculant, carrier, and other culture media cannot be evenly stirred directly in the barrel body.

[0010] To facilitate directly putting the brown sugar, inoculant, carrier, and other culture media into the pre-stirring filter cylinder for pre-stirring, the diameter of the annular side plate increases from bottom to top, and the orthographic projection of the feeding port is located within the opening formed at the upper end of the annular side plate.

[0011] There is a gap between the bottom stirring rod and the bottom plate. To facilitate stirring and cleaning the brown sugar, inoculant, carrier, or other culture media on the upper surface of the bottom plate out of the pre-stirring filter cylinder, multiple groups of brush filaments are provided on the side of the bottom stirring rod close to the bottom plate, and one end of the brush filaments extends downward to the bottom plate. The length of the brush filaments is greater than the distance from the side of the bottom stirring rod close to the bottom plate to the upper surface of the bottom plate.

[0012] To facilitate the brown sugar, inoculant, carrier, or other culture media to be stirred by the second stirring rod on the bottom plate and then flow out of the pre-stirring filter cylinder to mix with the water in the barrel body, the filter holes on the annular side plate are the first filter holes, and the filter holes on the bottom plate are the second filter holes. The aperture of the second filter hole is smaller than that of the first filter hole, preventing the inoculant, carrier, or other culture media from leaking out of the pre-stirring filter cylinder through the filter holes with a larger diameter without being stirred by the second stirring rod.

[0013] Regarding the respective setting intervals of the first filter holes and the second filter holes, the vertical interval between adjacent two second filter holes is smaller than the vertical interval between adjacent two first filter holes, making the second filter holes on the bottom plate form small-diameter and dense filter holes, so that the brown sugar, inoculant, carrier, or other culture media can only flow out of the pre-stirring filter cylinder to mix fully with the water in the barrel body after being stirred to a certain extent.

[0014] The specific structure of the above-mentioned bottom stirring rod is that the bottom stirring rod includes a left stirring bottom rod and a right stirring bottom rod symmetrically arranged on both sides of the stirring shaft, and the brush filaments are respectively arranged on the lower surfaces of the left stirring bottom rod and the right stirring bottom rod.

[0015] To facilitate the brush filaments of the bottom stirring rod to contact the brown sugar, inoculant, carrier, or other culture media on the bottom plate over a larger area driven by the stirring shaft, the brush filaments on the left stirring bottom rod are the first brush filaments, and the brush filaments on the right stirring bottom rod are the second brush filaments. The rotation trajectories of multiple first brush filaments and the rotation trajectories of multiple second brush filaments do not interfere with each other.

[0016] In order to increase the oxygen supply in the barrel, an aeration head is also provided in the barrel. The aeration head is connected to an external oxygen pump through a pipeline, and the pipeline is passed through the cross bar.

[0017] When brown sugar or carrier is put into the pre-mixing filter cartridge, temporary accumulation will occur. To prevent the brown sugar or carrier from being directly stirred out of the pre-mixing filter cartridge by the second stirring rod above when rotating with the stirring shaft, the height of the second stirring rod at the top is set at 1 / 3-2 / 3 of the height of the pre-mixing filter cartridge.

[0018] The beneficial effects of the utility model are:

[0019] By pre-stirring brown sugar, bacterial agents, carriers and other culture media with the water on the upper part of the cylinder in the pre-stirring filter cartridge, the liquid flows out from the first filter hole and the second filter hole to the outside of the pre-stirring filter cartridge while stirring and fully mixes with the water in the cylinder, so as to centrally disperse the brown sugar, bacterial agents, carriers and other culture media and mix them with water, and avoid the phenomenon of uneven stirring and dispersion of brown sugar, bacterial agents, carriers or other culture media, especially carriers with different solubilities, when stirred directly in the cylinder due to the large proportion of water in the cylinder. Fully mixing the microbial agent with water can ensure that the microorganisms are evenly distributed in the liquid culture medium, which helps to avoid the formation of microorganisms in the culture medium Aggregates, thereby promoting the formation and uniform growth of single colonies; full mixing can ensure that the microorganisms are fully in contact with the nutrients in the culture medium, thereby improving the efficiency of nutrient absorption;

[0020] The aeration head increases the oxygen supply to the culture solution, and the stirring of the first stirring rod and the second stirring rod is more conducive to the distribution of oxygen in the culture solution. The stirring of oxygen and the first stirring rod and the second stirring rod also helps to evenly distribute nutrients, prevent microorganisms from settling in the culture solution, and help remove metabolic waste.

[0021] The first brush wire on the left stirring bottom rod and the second brush wire on the right stirring bottom rod can clean the culture medium such as the carrier on the bottom plate in time to avoid accumulation or the phenomenon of not being dispersed. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Refer to Figure 1 As shown, a microbial inoculant propagation device includes a barrel body 1 and a stirrer arranged therein. A cover body 11 is provided at the upper part of the barrel body 1, and a feeding port 12 is provided on the cover body 11. The stirrer includes a driving motor 3, a vertically arranged stirring shaft 2 and a plurality of first stirring rods 4 arranged thereon. The driving motor 3 is arranged on the cover body 11, and the driving motor 3 is connected to the stirring shaft 2 to drive the stirring shaft 2 to rotate. The lower end of the stirring shaft 2 is rotatably connected to the bottom of the barrel body 1 through a bearing.

[0030] Refer to Figure 2 and Figure 4 As shown, the microbial inoculant propagation device further includes a pre-stirring filter cylinder 5 arranged at the upper part inside the barrel body 1. The pre-stirring filter cylinder 5 is arranged above the first stirring rod 4. The pre-stirring filter cylinder 5 includes an annular side plate 51 and a bottom plate 52 which are integrally formed and are both provided with leakage holes. The middle part of the bottom plate 52 is rotatably connected to the stirring shaft 2, and the upper part of the annular side plate 51 is connected to the inner wall of the barrel body 1 through a cross bar 6.

[0031] Refer to Figure 3 and Figure 4 As shown, a plurality of second stirring rods 7 are further arranged on the stirring shaft 2. The second stirring rods 7 are located inside the pre-stirring filter cylinder 5, and the second stirring rod 7 located below is the bottom stirring rod 71. The bottom stirring rod 71 is parallel to the bottom plate 52. One end of the bottom stirring rod 71 extends towards the annular side plate 51 and does not interfere with the annular side plate 51. The lengths of the plurality of second stirring rods 7 decrease successively from bottom to top. When brown sugar or carrier is put into the pre-stirring filter cylinder 5, it will temporarily accumulate. To prevent the second stirring rod 7 above from directly stirring the brown sugar or carrier out of the pre-stirring filter cylinder 5 when rotating along with the stirring shaft 2, the height of the uppermost second stirring rod 7 is set at 1 / 3 - 2 / 3 of the height of the pre-stirring filter cylinder 5.

[0032] To facilitate the direct placement of brown sugar, bacterial agents, carriers, and other culture media into the pre-stirring filter cylinder 5 for pre-stirring, the diameter of the annular side plate 51 increases from bottom to top, and the orthographic projection of the feed inlet 12 is located within the opening formed at the upper end of the annular side plate 51. To facilitate the brown sugar, bacterial agents, carriers, or other culture media on the bottom plate 52 to flow out of the pre-stirring filter cylinder 5 after being stirred by the second stirring rod 7 and mix with the water in the barrel body 1, the filter holes on the annular side plate 51 are the first filter holes 511, and the filter holes on the bottom plate 52 are the second filter holes 521. The aperture of the second filter hole 521 is smaller than that of the first filter hole 511, preventing the bacterial agents, carriers, or other culture media from leaking out of the pre-stirring filter cylinder 5 through the larger-diameter filter holes without being stirred by the second stirring rod 7.

[0033] Regarding the respective setting intervals of the above-mentioned first filter holes 511 and second filter holes 521, the vertical interval between adjacent two second filter holes 521 is smaller than the vertical interval between adjacent two first filter holes 511, making the second filter holes 521 on the bottom plate 52 form small-diameter and dense filter holes, so that the brown sugar, bacterial agents, carriers, or other culture media can only flow out of the pre-stirring filter cylinder 5 and mix fully with the water in the barrel body 1 after being stirred to a certain extent.

[0034] There is a gap between the bottom stirring rod 71 and the bottom plate 52. To facilitate the stirring and cleaning of the brown sugar, bacterial agents, carriers, or other culture media on the upper surface of the bottom plate 52 out of the pre-stirring filter cylinder 5, multiple groups of brush filaments are provided on the side of the bottom stirring rod 71 close to the bottom plate 52. One end of the brush filaments extends downward to the bottom plate 52, and the length of the brush filaments is greater than the distance from the side of the bottom stirring rod 71 close to the bottom plate 52 to the upper surface of the bottom plate 52.

[0035] See Figure 2 and Figure 3 As shown, the specific structure of the above-mentioned bottom stirring rod 71 is that the bottom stirring rod 71 includes a left stirring bottom rod 711 and a right stirring bottom rod 713 symmetrically arranged on both sides of the stirring shaft 2, and the brush filaments are respectively arranged on the lower surfaces of the left stirring bottom rod 711 and the right stirring bottom rod 713. To facilitate the brush filaments of the bottom stirring rod 71 to contact the brown sugar, bacterial agents, carriers, or other culture media on the bottom plate 52 over a larger area under the drive of the stirring shaft 2, the brush filaments on the left stirring bottom rod 711 are the first brush filaments 712, and the brush filaments on the right stirring bottom rod 713 are the second brush filaments 714. The rotation trajectories of the multiple first brush filaments 712 and the rotation trajectories of the multiple second brush filaments 714 do not interfere with each other.

[0036] The functions that the above structure can achieve are as follows: Inject water at a suitable temperature required for the microbial inoculant into the barrel body 1, with the water surface not higher than the upper end face of the pre-stirring filter cylinder 5 and not lower than the lower end face of the pre-stirring filter cylinder 5. Then, put a certain proportion of brown sugar, inoculant, carrier, and other culture media into the pre-stirring filter cylinder 5. By starting the stirrer, use the second stirring rod 7 to pre-stir the brown sugar, inoculant, carrier, and other culture media in the pre-stirring filter cylinder 5, so that the brown sugar, inoculant, carrier, and other culture media are evenly mixed in the water, and flow out of the pre-stirring filter cylinder 5 through the filter holes on the annular side plate 51 and the bottom plate 52, avoiding the phenomenon that the brown sugar, inoculant, carrier, and other culture media cannot be stirred evenly when directly stirred in the barrel body 1.

[0037] To increase the supply of oxygen in the barrel body 1, an aeration head 8 is also provided in the barrel body 1. The aeration head 8 is located on one side of the first stirring rod. The aeration head 8 is connected to an external oxygen pump through a pipeline 9. The oxygen pump and the aeration head are both prior arts. The pipeline 9 passes through the cross bar 6 from the feed inlet 12 and is connected to the aeration head 8. The cross bar 6 plays a role in limiting and fixing the pipeline 9. The aeration head 8 is located at the bottom of the barrel body 1 and below the lowermost first stirring rod 4. The aeration head 8 is fixedly connected to the inner wall of the barrel body 1 through a bracket 10 to prevent the aeration head 8 from shaking.
