However, this device does not have a corresponding structure to process the by-products generated during the process of treating fresh chicken manure, resulting in energy waste. Therefore, the present invention proposes a device and a usage method for producing solid organic fertilizer by using fresh chicken manure to solve the above problems. Summary of the Invention

[0005] To solve the above problems, the present invention provides a device and a usage method for producing solid organic fertilizer by using fresh chicken manure to make full use of the biogas generated during the fermentation process of fresh chicken manure and save energy.

[0006] To achieve the above object, the technical solution of the present invention is as follows: An apparatus and a method for using the same for producing solid organic fertilizer from fresh chicken manure, including a fermentation tank and a processing box. A heating device is installed at the bottom of the fermentation tank. An extrusion device and a baking device are installed in the processing box. The extrusion device is connected to a first driving member. A rack is fixedly connected to the output shaft of the first driving member. The rack meshes with a gear. The gear is coaxially fixedly connected to a first bevel gear. A fixed shaft fixedly connected to the processing box is rotatably fitted in the middle of both the gear and the first bevel gear. A second bevel gear meshes with the first bevel gear on the side away from the rack. The second bevel gear is coaxially fixedly connected to a connecting shaft. One end of the connecting shaft away from the second bevel gear is located in the fermentation tank and is coaxially fixedly connected to a third bevel gear. A fourth bevel gear meshes with the top of the third bevel gear. The fourth bevel gear is coaxially fixedly connected to a stirring shaft. The stirring shaft extends downward to the bottom of the fermentation tank. Stirring blades are fixedly connected to the stirring shaft. A plurality of biogas pipes are communicated with the top of the fermentation tank. The biogas pipes are respectively communicated with the baking device and the heating device.

[0007] Advantages of adopting the above solution: 1. Using the driving member in an extrusion device to extrude the fermented fresh chicken manure can extrude the liquid in the fresh chicken manure, accelerating the formation of solid organic fertilizer.

[0008] 2. During the extrusion process, the same driving member is used for force transmission to stir the fermentation tank. The structure is ingenious and the energy consumption is reduced. Stirring the fresh chicken manure in the fermentation tank promotes the fermentation of the fresh chicken manure, reduces the fermentation time of the fresh chicken manure, and increases the fermentation efficiency of the fresh chicken manure.

[0009] 3. The increased fermentation efficiency of fresh chicken manure forms a large amount of biogas and utilizes the biogas to heat the fermentation tank, further increasing the fermentation efficiency of fresh chicken manure. At the same time, it provides energy for the baking device to bake the extruded fresh chicken manure, accelerating the evaporation of moisture in the fresh chicken manure and enabling the fresh chicken manure to further quickly form solid organic fertilizer. Thus, the biogas generated during the fermentation process of fresh chicken manure is fully utilized, saving energy consumption.

[0010] Furthermore, the extrusion equipment includes a processing box, the first driving member includes a hydraulic cylinder fixedly connected to the processing box, the bottom of the hydraulic cylinder output shaft is coaxially fixedly connected to a connecting rod, the bottom of the connecting rod is fixedly connected to a pressure plate, the pressure plate is located in the processing box and slidably cooperates with the inner wall of the processing box, a filter plate fixedly connected to the inner wall of the processing box is provided below the pressure plate, a first discharge port is provided on one side of the processing box, the first discharge port is connected to a first solenoid valve, the side of the filter plate close to the first discharge port is lower than the side of the filter plate away from the first discharge port; the baking equipment includes a baking box, the baking box is connected to the first discharge port, a stirring assembly, a first burner and an air outlet assembly are installed in the baking box, the stirring assembly includes an auger, and the side of the auger close to the processing box is connected to a second driving member; the first burner is installed in the baking box, the biogas pipe includes a first biogas pipe and a second biogas pipe, and the first burner is connected to the first biogas pipe; the baking box is provided with a second discharge port on the side away from the processing box, the air outlet assembly includes an air outlet, the air outlet is connected to an air outlet pipe, and the air outlet pipe is fixedly connected to the top of the baking box.

Using an auger to stir the squeezed fresh chicken manure can make the fresh chicken manure turn over continuously during baking, bake the fresh chicken manure evenly, and break up the lumps or adhesions of fresh chicken manure. The auger can also facilitate the transportation of fresh chicken manure while stirring it. Since fresh chicken manure will generate steam or other gases during the baking process, the steam or other gases are discharged from the outlet pipe to avoid explosion or other dangers caused by the accumulation of a large amount of gas in the baking oven. Discharging the steam can increase the efficiency of baking fresh chicken manure and reduce the baking time of fresh chicken manure.

[0012] Furthermore, the heating device comprises a partition, which is fixedly connected to the inner wall of the bottom of the fermentation tank, and a second heater is fixedly connected to the bottom of the partition, and the second heater is connected to the second biogas pipe.

[0024] Step 2, dehydrating the fermented fresh chicken manure: opening the second solenoid valve and the material conveying pump, and inputting the fermented fresh chicken manure at the bottom of the fermentation tank into the processing box through the feed pipe, and then opening the first driving member, so that the hydraulic cylinder output shaft outputs the extrusion connecting rod and the pressing plate, and the pressing plate squeezes the fresh chicken manure in the processing box, so that the liquid in the fresh chicken manure is filtered from the filter plate, thereby realizing the dehydration of the fresh chicken manure.

[0025] Step 3, accelerating the fermentation of fresh chicken manure in the fermentation tank: When the output shaft of the hydraulic cylinder outputs, it drives the rack to move vertically downward.

[0039] A method for using a device for producing solid organic fertilizer from fresh chicken manure: includes the following steps:

[0040] Step 1, ferment fresh chicken manure: Continuously convey the "rolling mountain chicken" fresh chicken manure into the fermentation tank 1, so that the "rolling mountain chicken" fresh chicken manure ferments in the fermentation tank 1.

[0041] Step 2, dehydrate the fermented fresh chicken manure: Open the second solenoid valve 4 and the material delivery pump 5, and input the fermented "Rolling Mountain Chicken" fresh chicken manure at the bottom of the fermentation tank 1 into the treatment tank 6 through the feed pipe 3. At this time, turn on the first driving member to make the output shaft of the hydraulic cylinder 7 output the extrusion connecting rod 8 and the pressing plate 9. The pressing plate 9 extrudes the "Rolling Mountain Chicken" fresh chicken manure in the treatment tank 6, so that the liquid in the "Rolling Mountain Chicken" fresh chicken manure is filtered through the filter plate 10, realizing the dehydration of the "Rolling Mountain Chicken" fresh chicken manure and accelerating the formation of solid organic fertilizer.

[0042] Step 3, stir the fresh chicken manure in the fermentation tank 1 to accelerate fermentation: When the output shaft of the hydraulic cylinder 7 outputs, it drives the rack 14 to move vertically downward. The movement of the rack 14 drives the gear 15 and the first bevel gear 16 to rotate. The first bevel gear 16 drives the second main gear 15, the connecting shaft 19 and the third bevel gear 20 to rotate. The third bevel gear 20 drives the fourth bevel gear 21 and the stirring shaft 22 to rotate. At this time, the slider 26 rotates in the chute of the limiting block 25, and the limiting block 25 can conveniently limit the stirring shaft 22 and fix the stirring shaft 22 to a certain extent. The stirring shaft 22 rotates to drive the stirring blades 23 to stir the "Rolling Mountain Chicken" fresh chicken manure in the fermentation tank 1, improving the fermentation speed and quickly generating a large amount of biogas. During the extrusion process, the force is transmitted by using the same driving member to stir the fermentation tank 1. The structure is ingenious and the energy use is reduced. Stirring the "Rolling Mountain Chicken" fresh chicken manure in the fermentation tank 1 promotes the fermentation of the "Rolling Mountain Chicken" fresh chicken manure, reduces the fermentation time of the "Rolling Mountain Chicken" fresh chicken manure, and increases the fermentation efficiency of the "Rolling Mountain Chicken" fresh chicken manure.

[0043] Step 4, stir and convey the dehydrated fresh chicken manure: After the "Rolling Mountain Chicken" fresh chicken manure is dehydrated, raise the pressing plate 9 and open the first solenoid valve 12 to make the "Rolling Mountain Chicken" fresh chicken manure on the filter plate 10 fall into the baking oven 28. The side of the filter plate 10 close to the first discharge port is lower than the side of the filter plate 10 away from the first discharge port, which can facilitate the "Rolling Mountain Chicken" fresh chicken manure to slide down along the inclined direction of the filter plate 10 after extrusion and be output from the first discharge port. Start the motor 31, and the output shaft of the motor 31 rotates to drive the rotating shaft 30 and the spiral blade 32 to rotate. The spiral blade 32 can stir the extruded "Rolling Mountain Chicken" fresh chicken manure, so that the "Rolling Mountain Chicken" fresh chicken manure keeps turning during baking, bake the "Rolling Mountain Chicken" fresh chicken manure evenly, and can break up the agglomerated or adhered "Rolling Mountain Chicken" fresh chicken manure. The spiral blade 32 can also facilitate the transportation of the "Rolling Mountain Chicken" fresh chicken manure while stirring the "Rolling Mountain Chicken" fresh chicken manure.

[0044] Step 5: Use the biogas in the fermentation tank 1: The biogas in the fermentation tank 1 is transported through the first biogas pipe 34 to the first burner 29 in the baking oven 28. The biogas burns in the first burner 29 to generate heat for baking the baking oven 28. At the same time, the biogas is transported through the second biogas pipe 35 to the second burner. The biogas burns in the second burner to generate heat for heating the fermentation tank 1. Utilizing the biogas in the fermentation tank 1 itself to provide energy for the second heater 39 can reduce the use of other energy sources. The second heater 39 heating the fresh chicken manure of "Rolling Hill Chicken" in the fermentation tank 1 can increase the fermentation time of the fresh chicken manure of "Rolling Hill Chicken", quickly form organic fertilizer using the fresh chicken manure of "Rolling Hill Chicken", and since biogas is a clean energy source, it avoids environmental pollution. Using biogas to heat the fermentation tank 1 further increases the fermentation efficiency of the fresh chicken manure of "Rolling Hill Chicken", and at the same time provides energy for the baking equipment to bake the extruded fresh chicken manure of "Rolling Hill Chicken", accelerating the evaporation of water in the fresh chicken manure of "Rolling Hill Chicken" and enabling the fresh chicken manure of "Rolling Hill Chicken" to further quickly form solid organic fertilizer. Thus, the biogas generated during the fermentation process of the fresh chicken manure of "Rolling Hill Chicken" is fully utilized, saving energy use.

[0045] Step 6: Discharge the fermented fresh chicken manure, the liquid filtered from the fresh chicken manure, and the waste gas in the baking oven 28: Open the third solenoid valve 36 to discharge the fresh chicken manure of "Rolling Hill Chicken" that has been stirred and baked in the baking oven 28 from the second discharge port. Open the fourth solenoid valve 40 to discharge the liquid in the treatment tank 6 from the fourth discharge port. Discharge the waste gas in the baking oven 28 from the exhaust pipe 37. Since steam or other gases are generated during the baking process of the fresh chicken manure of "Rolling Hill Chicken", discharging the steam or other gases from the exhaust pipe 37 avoids explosion or other dangers caused by the accumulation of a large amount of gas in the baking oven 28, and discharging the steam can increase the baking efficiency of the fresh chicken manure of "Rolling Hill Chicken" and reduce the baking time of the fresh chicken manure of "Rolling Hill Chicken".
