In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-5, an oxygen supply device for agricultural microbial fertilizer fermentation comprises an oxygen supply box 1, wherein a vortex tube 3, an air inlet tube 2 communicated with the vortex tube 3, a hot air tube 4 and a cold air tube 5 are arranged in the oxygen supply box 1, a three-way tube 9 is arranged between the hot air tube 4 and the cold air tube 5, a first exhaust tube 10 communicated with the hot air tube 4 is arranged on the hot air tube 4, a second exhaust tube 11 communicated with the cold air tube 5 is arranged on the cold air tube 5, the first exhaust tube 10 and the three-way tube 9 are horizontally arranged at the same horizontal height, and the second exhaust tube 11 and the three-way tube 9 are also horizontally arranged at the same horizontal height.

The hot air pipe 4 and the cold air pipe 5 are connected with a sealing plug 6 in a sealing and rotating mode, an air groove 601 is formed in the upper end of the sealing plug 6, a driving mechanism for driving the sealing plug 6 to rotate is arranged in the oxygen supply box 1, and the three-way pipe 9 is communicated with a plurality of air conveying pipes 16.

The actuating mechanism is including running through the temperature sensing pipe 8 of oxygen suppliment case 1 bottom, and temperature sensing pipe 8 intussuseption is filled with the thermal expansion liquid, and is specific, and the thermal expansion liquid adopts the liquid medium that easily receives temperature variation and breathing such as kerosene, dichloromethane, methyl alcohol. The temperature sensing tube 8 is internally connected with a piston 12 in a sealing and sliding manner, the piston 12 is made of a magnetic material, an iron sheet 15 is embedded in the side wall of each sealing plug 6, and the two sealing plugs 6 are respectively and rotatably arranged at the inner bottoms of the hot air tube 4 and the cold air tube 5 through spring shafts 7.

The gas pipe 16 is composed of a plurality of hard pipelines and a corrugated pipe 17, the corrugated pipe 17 is arranged between two adjacent hard pipelines, a plurality of bulges 19 are arranged on the side wall of each hard pipeline, and gas outlets 20 communicated with the insides of the hard pipelines are formed in the side walls of the bulges 19. It is worth mentioning that, through setting up arch 19, on the one hand, can increase the area of contact with fertilizer when the air current is discharged to improve oxygen suppliment efficiency, on the other hand, when bellows 17 is flexible, also can stir more fertilizer.

The bellows 17 is internally provided with a telescopic mechanism which can make the bellows extend and retract, the telescopic mechanism comprises a conductive spring 18 embedded in the bellows 17, a reed 14 is arranged in the first exhaust pipe 10, the reed 14 is made of piezoelectric ceramic materials, and the reed 14 is electrically connected with the conductive spring 18 through a control circuit. It should be noted that, under the action of the piezoelectric effect, the reed 14 generates an electrical signal with a small current intensity when vibrating, so that the power can be supplied to the conductive spring 18 by controlling the current, and the control circuit inputs a current with a constantly changing current magnitude to the conductive spring 18.

When the device is used, the whole device is placed in equipment, the temperature sensing pipes 8 and the air conveying pipes 16 are simultaneously embedded into the fertilizer, the air inlet pipe 2 is connected with the air compressor, and therefore high-speed airflow can be input into the air inlet pipe 2. When the airflow is input into the vortex tube 3 through the air inlet tube 2, the airflow is divided into two flows of cold and hot airflow, and the two flows of cold and hot airflow are respectively discharged into the hot air tube 4 and the cold air tube 5.

The thermal expansion liquid in the temperature sensing pipe 8 can expand to different heights according to the temperature of the fertilizer in the equipment, when the temperature of the fertilizer in the equipment is lower, the expansion height of the thermal expansion liquid is lower, the piston 12 is far away from the sealing plug 6, the magnetic attraction force between the magnetic piston 12 and the iron sheet 15 on the sealing plug 6 is weaker, the elastic force of the spring shaft 7 is relatively larger, so that the sealing plug 6 rotates to the state shown in figure 5, namely the communication area of the air groove 601 in the hot air pipe 4 and the three-way pipe 9 is larger, the communication area of the air groove 601 in the cold air pipe 5 and the three-way pipe 9 is smaller, therefore, the hot air content flowing into the three-way pipe 9 is larger, the cold air content is lower, the temperature of the whole air flow discharged from the air outlet 20 on the side wall of the air pipe 16 is higher, the temperature in the equipment can be increased, and the heat loss is prevented.

Relatively, when the temperature was higher in the equipment, then the thermal expansion liquid inflation height was higher, and piston 12 and sealing plug 6 are at a distance from closely, and magnetic attraction is greater than spring shaft 7 elastic force effect between piston 12 and the iron sheet 15, so sealing plug 6 will rotate to the state of figure 3, and the steam content of input three-way pipe 9 is lower promptly, and cold air content is higher, so can effectively cool down equipment, prevents that high temperature from causing the microorganism death.

Further, when partial air current of cold air pipe 5 is discharged through air groove 601 and second blast pipe 11, will make reed 14 continuously vibrate, reed 14 that adopts piezoelectric material to make will produce an electric signal, and input a current that the electric current size constantly changes to conducting spring 18 through control circuit, make conducting spring 18's contraction amplitude constantly change, so can arouse bellows 17 constantly flexible, so can pull the stereoplasm pipeline round trip movement of both sides, thereby stir fertilizer, make the combustion gas can fully contact with fertilizer, improve oxygen suppliment efficiency.

More remarkably, because the reed 14 is arranged in the first exhaust pipe 10, as can be seen from the above, when the temperature in the equipment is higher, the sealing plug 6 rotates to the state shown in fig. 3, the airflow discharged from the first exhaust pipe 10 is more and faster, so the vibration frequency of the reed 14 is accelerated, the expansion frequency of the conductive spring 18 is also accelerated, so the fertilizer can be stirred more frequently, the heat in the fertilizer is promoted to be distributed out, the temperature is quickly reduced, the microbial activity is kept, and when the temperature in the equipment is lower, the fertilizer stirring frequency is reduced, and the heat loss can be prevented.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
