DETAILED DESCRIPTION

[0037] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0038] Example:

[0039] See also Figure 1-7 , the present invention provides a technical solution:

[0040] A high-temperature composting fermentation system for organic fertilizer, comprising a fermentation tank 1, a water pump 14 and an air pump 11, wherein a support 8 is provided at the bottom of the fermentation tank 1, a sealing cover 12 is provided at the top of the fermentation tank 1, a pressure relief valve is provided on the sealing cover 12, and the sealing cover 12 is used to ensure that the internal pressure of the fermentation tank 1 is within a safe range during fermentation, and a thermometer is also provided on the sealing cover 12, and the sealing cover 12 is used to detect the temperature inside the fermentation tank 1, the sealing cover 12 is connected to the top of the conveying mechanism, and a distributor is provided between the fermentation tank 1 and the inside of the sealing cover 12;

[0041] The distributor includes a connecting seat cylinder 20 fixed in the sealing cover 12 through an inclined support arm 19, a rotating cylinder 39 extending through the connecting seat cylinder 20, and a rotating seat 17 connected to the top of the rotating cylinder 39. A plurality of groups of inclined blades 18 distributed at equal intervals are arranged on the side of the rotating seat 17. The rotating seat 17 is located on the upper end surface of the connecting seat cylinder 20.

[0042] A bearing is arranged inside the connecting seat cylinder 20, and the bearing is sleeved on the rotating cylinder 39, so that the rotation of the rotating seat 17 and the rotating cylinder 39 is smoother.

[0043] The conveying mechanism includes a conveying trough 2 seated on the ground by supporting legs 4, a feeding hopper 5 fixed at the upper end of the bottom of the conveying trough 2, and a conveying belt 6 arranged inside the conveying trough 2 and driven by a second motor 3;

[0044] A driving roller and a driven roller are respectively provided at both ends of the conveying trough 2, and a conveying belt 6 is connected between the driving roller and the driven roller, and a second motor 3 is fixed to the bottom side of the conveying trough 2, and an output end of the second motor 3 is connected to the driving roller, and the second motor 3 drives the driving roller to rotate, so that the driving roller drives the conveying belt 6 to rotate;

[0045] The discharge pipe 9 at the top of the conveying trough 2 is connected to the upper side of the sealing cover 12 , and the discharge pipe 9 is located directly above the corresponding inclined blade 18 .

[0046] The organic fertilizer raw material is fed into the feeding hopper 5, and the organic fertilizer raw material falls from the bottom of the feeding hopper 5 to the conveyor belt 6. Under the rotation of the conveyor belt 6, the organic fertilizer raw material is discharged through the discharge pipe 9. At this time, the organic fertilizer raw material falls onto the corresponding inclined blades 18. The inclined blades 18 drive the rotating seat 17 and the rotating drum 39 to rotate under the impact of the falling organic fertilizer raw material;

[0047] Under the rotation of the rotating seat 17, each group of inclined blades 18 on the rotating seat 17 contacts the falling organic fertilizer raw materials, so that the inclined blades 18 throw out the organic fertilizer raw materials on the inclined blades 18, so that the organic fertilizer raw materials fall evenly, and then the organic fertilizer raw materials are evenly laid in the fermentation tank 1;

[0048] Note that the organic fertilizer raw materials only need to cover the fermentation tank 1, thereby preventing the organic fertilizer raw materials from covering the rotating seat 17 and preventing the rotating seat 17 and the rotating drum 39 from stopping.

[0049] When the conveying mechanism conveys the organic fertilizer raw material into the fermentation tank 1, the organic fertilizer raw material falls to the distributor and then pushes the distributor to rotate to distribute the organic fertilizer raw material in the fermentation tank 1, so that the lower part of the distributor is located at the center of the organic fertilizer raw material, that is, after the organic fertilizer raw material covers the fermentation tank 1, the drum 39 is located in the middle of the organic fertilizer raw material;

[0050] The water pump 14 is used to introduce clean water into the organic fertilizer raw material through the distributor. The water outlet of the water pump 14 is connected to the water diversion pipe 15. The middle part of the rotating seat 17 is provided with a water diversion hole 38 connected with the inside of the rotating drum 39. The water diversion pipe 15 penetrates the sealing cover 12 and is inserted into the water diversion hole 38 (so that when the rotating seat 17 rotates, it will not affect the water diversion pipe 15 from injecting clean water into the water diversion hole 38). A clean water discharge port 40 is provided on the surface of the rotating drum 39.

[0051] The water pump 14 works to introduce clean water into the water inlet hole 38 through the water inlet pipe 15, so that the clean water enters the drum 39 and is finally discharged to the organic fertilizer raw material through the clean water outlet 40;

[0052] Since the drum 39 is located in the middle of the organic fertilizer raw material, the clean water discharged through the clean water outlet 40 can be quickly and evenly diffused to the surroundings, and the clean water soaks the organic fertilizer raw material from the middle of the organic fertilizer raw material, thereby improving the rapid and uniform soaking of the organic fertilizer raw material;

[0053] The organic fertilizer raw material is too dry, which is not conducive to the reproduction and growth of microorganisms therein, and may further affect the normal fermentation of the organic fertilizer raw material. Therefore, it is necessary to inject clean water into the organic fertilizer raw material. Since the organic fertilizer raw material generates high temperature during fermentation, after the thermometer detects that the temperature in the fermentation tank 1 is too high, it is necessary to inject clean water into the organic fertilizer raw material to achieve the purpose of cooling, thereby providing a suitable environment for the growth or reproduction of microorganisms in the organic fertilizer raw material.

[0054] The inner wall of the fermentation tank 1 is provided with annular tubes 21 distributed up and down, the air pump 11 is connected to the annular tube 21 through the air pipe, and air outlet holes are evenly distributed at the bottom of the annular tube 21; the air pipe includes a main air pipe 16 connected to the air outlet of the air pump 11 and a branch pipe 13 connected to the end of the main air pipe 16, and the branch pipe 13 passes through the fermentation tank 1 and is connected to the corresponding annular tube 21.

[0055] The air pump 11 works to introduce outside air into the upper and lower groups of annular tubes 21 through the main air pipe 16 and the branch pipe 13, respectively, until the air in the annular tubes 21 is evenly diffused to the organic fertilizer raw material through the air outlet holes at the bottom of the annular tubes 21, providing oxygen for the growth or reproduction of microorganisms, thereby ensuring the normal fermentation of the organic fertilizer raw material.

[0056] An annular filter screen 33 is provided at the lower end of the fermentation tank 1, and a bottom plate 31 fixedly connected to the inner wall of the fermentation tank 1 is provided on the top of the annular filter screen 33. Two groups of arc-shaped protrusions 32 are symmetrically provided on the upper edge of the bottom plate 31, and an opening 36 for inserting the piston rod 29 is provided in the middle of the bottom plate 31;

[0057] Connecting arms 30 are symmetrically arranged on both sides of the top of the piston column 29. The roller 292 installed at the lower end of the connecting arm 30 through the wheel frame 291 is located on the upper edge of the bottom plate 31. The column 26 fixed at the upper end of the connecting arm 30 penetrates the rotating plate 27 inside the fermentation tank 1 and is connected to a stirring mechanism.

[0058] The middle part of the stirring mechanism passes through the lower part of the distributor, and the stirring mechanism is located inside the annular tube 21. The stirring mechanism includes a sleeve 24 sleeved on the upper and lower parts of the rotating drum 39, a horizontal plate 22 symmetrically arranged on the side of the sleeve 24, and a stirring plate 23 connected to the side of the sleeve 24; the ends of the horizontal plates 22 are fixedly connected to the columns 26.

[0059] Since the sleeve 24 is sleeved on the rotating drum 39, when the column 26 and the stirring mechanism move up and down, it can be ensured that the column 26 and the stirring mechanism do not deviate when moving up and down.

[0060] The surface of the column 26 is provided with a cleaning rod 25 which is closely attached to the side wall of the fermentation tank 1, and the upper end surface of the rotating disk 27 is provided with a scraper 28 and a liquid leakage net 271;

[0061] A first motor 35 is installed at the bottom of the fermentation tank 1. The rotating shaft 34 at the output end of the first motor 35 passes through the annular filter 33, the opening 36 and the piston column 29 in sequence and is fixedly connected to the middle part of the lower end of the rotating disk 27. A return spring 37 located between the rotating disk 27 and the piston column 29 is also sleeved on the rotating shaft 34.

[0062] A discharge groove 7 is also provided on the side of the fermentation tank 1, and the bottom height of the discharge groove 7 is flush with the upper end surface of the rotating disk 27. After the gate on the discharge groove 7 is opened, the first motor 35 drives the rotating disk 27 to rotate through the rotating shaft 34, so that the scraper 28 on the rotating disk 27 pushes the fermentation residue produced after the organic fertilizer raw material is fermented out of the fermentation tank 1 through the discharge groove 7.

[0063] Two groups of flushing pipes 10 are symmetrically connected to the bottom of the side of the fermentation tank 1. One group of flushing pipes 10 is connected to a flushing pump. The flushing pump fills high-pressure water into the annular filter 33 to clean the inner wall of the annular filter 33. At the same time, the valve on the other group of flushing pipes 10 is opened to discharge the sewage and fermentation liquid inside the annular filter 33.

[0064] The present invention also provides a fermentation method of an organic fertilizer high temperature composting fermentation system, which specifically comprises the following steps:

[0065] S1, conveying organic fertilizer raw materials into the fermentation tank 1 through the conveying mechanism, and after the organic fertilizer raw materials fall into the distributor, the distributor is driven to rotate to distribute the organic fertilizer raw materials in the fermentation tank 1;

[0066] S2, water pump 14 introduces clean water into the organic fertilizer raw material through a distributor;

[0067] S3, the air pump 11 introduces air into the fermentation tank 1 through the air pipe and the annular tube 21, the organic fertilizer raw material ferments in the fermentation tank 1, and the formed fermentation liquid falls into the annular filter 33 through the leakage net 271 and the opening 36;

[0068] S4, the first motor 35 drives the rotating disk 27, the column 26 and the stirring mechanism to rotate through the rotating shaft 34, so that the column 26 and the stirring mechanism and the scraper 28 on the rotating disk 27 stir the organic fertilizer raw material;

[0069] At the same time, the column 26 drives the piston column 29 to rotate, so that the roller 292 rolls onto the arc-shaped protrusion 32, the column 26 and the stirring mechanism move upward, and the roller 292 rolls down from the arc-shaped protrusion 32, and the column 26 and the stirring mechanism move downward. The column 26 and the stirring mechanism move up and down to stir the organic fertilizer raw material;

[0070] After the column 26 and the stirring mechanism move downward, the piston column 29 is inserted into the annular filter screen 33 through the opening 36 to squeeze the fermentation liquid in the annular filter screen 33 out of the fermentation tank 1;

[0071] S5. After the fermentation is completed, the first motor 35 drives the rotating disk 27, the column 26 and the stirring mechanism to rotate through the rotating shaft 34. The cleaning rod 25 on the column 26 cleans the inner wall of the fermentation tank 1. The stirring mechanism stirs the fermentation residue in the fermentation tank 1 and drops it onto the rotating disk 27. The scraper 28 on the rotating disk 27 pushes the fermentation residue out of the fermentation tank 1.

[0072] Specifically, when in use, the output end of the second motor 3 is connected to the active roller, and the second motor 3 drives the active roller to rotate, so that the active roller drives the conveyor belt 6 to rotate, and the organic fertilizer raw material is put in through the feeding hopper 5, and the organic fertilizer raw material falls from the bottom of the feeding hopper 5 to the conveyor belt 6. Under the rotation of the conveyor belt 6, the organic fertilizer raw material is discharged through the discharge pipe 9. At this time, the organic fertilizer raw material falls on the corresponding inclined blades 18, and the inclined blades 18 drive the rotating seat 17 and the rotating drum 39 to rotate under the impact of the falling organic fertilizer raw material;

[0073] Under the rotation of the rotating seat 17, each group of inclined blades 18 on the rotating seat 17 contacts the falling organic fertilizer raw materials, so that the inclined blades 18 throw out the organic fertilizer raw materials on the inclined blades 18, so that the organic fertilizer raw materials fall evenly, and then the organic fertilizer raw materials are evenly laid in the fermentation tank 1;

[0074] The lower part of the distributor is located at the center of the organic fertilizer raw material, that is, after the organic fertilizer raw material covers the fermentation tank 1, the drum 39 is located in the middle of the organic fertilizer raw material;

[0075] The water pump 14 works to introduce clean water into the water inlet hole 38 through the water inlet pipe 15, so that the clean water enters the drum 39 and is finally discharged to the organic fertilizer raw material through the clean water outlet 40. The clean water soaks the organic fertilizer raw material from the middle of the organic fertilizer raw material, thereby improving the rapid and uniform soaking of the organic fertilizer raw material.

[0076] The air pump 11 works to introduce external air into the upper and lower groups of annular tubes 21 through the main air pipe 16 and the branch pipe 13, respectively, until the air in the annular tubes 21 is evenly diffused to the organic fertilizer raw material through the air outlet holes at the bottom of the annular tubes 21, providing oxygen for the growth or reproduction of microorganisms, thereby ensuring the normal fermentation of the organic fertilizer raw material;

[0077] The organic fertilizer raw material is fermented in the fermentation tank 1, and the fermented liquid formed falls to the upper surface of the bottom plate 31 through the liquid leakage net 271, flows along the upper surface of the bottom plate 31 to the opening 36, and falls into the annular filter 33 through the opening 36;

[0078] During the fermentation process, the organic fertilizer raw material needs to be stirred. At this time, the first motor 35 drives the rotating disk 27, the column 26 and the stirring mechanism to rotate through the rotating shaft 34, so that the column 26 and the stirring mechanism and the scraper 28 on the rotating disk 27 stir the organic fertilizer raw material;

[0079] At this time, the rotating disk 27 drives the column 26 to rotate, and the column 26 drives the horizontal plate 22 and the stirring plate 23 to rotate to stir the organic fertilizer raw materials.

[0080] At the same time, the column 26 drives the piston column 29 to rotate, so that the roller 292 rolls onto the arc-shaped protrusion 32 (such as Figure 6 As shown in FIG. 2 , the column 26 and the stirring mechanism move upward, at which time the return spring 37 is in a compressed state, and then the roller 292 rolls down from the arc-shaped protrusion 32 (as shown in FIG. 2 ). Figure 7 As shown), under the elastic force of the return spring 37 on the piston column 29, the column 26 and the stirring mechanism move downward, and the column 26 and the stirring mechanism move up and down to stir the organic fertilizer raw material;

[0081] After the column 26 and the stirring mechanism move downward, the piston column 29 is inserted into the annular filter screen 33 through the opening 36, and the fermentation liquid in the annular filter screen 33 is squeezed out of the fermentation tank 1 through the corresponding flushing pipe 10;

[0082] After the fermentation is finished, the first motor 35 drives the rotating disk 27, the column 26 and the stirring mechanism to rotate through the rotating shaft 34, the cleaning rod 25 on the column 26 cleans the inner wall of the fermentation tank 1, the stirring mechanism stirs the fermentation residue in the fermentation tank 1 and then drops it onto the rotating disk 27, and the scraper 28 on the rotating disk 27 pushes the fermentation residue out of the fermentation tank 1 through the discharge groove 7;
