Description

Technical Field

[0001] The invention relates to the technical field of straw recycling, in particular to a comprehensive production system for producing organic fertilizer by fermentation using waste straw. Background Art

[0002] As we all know, the traditional way to deal with straw is to directly discard or burn it. This treatment method not only causes waste of resources but also pollutes the environment. Therefore, with the progress of society and the strengthening of environmental control, some technologies for recycling straw have emerged in recent years. At present, straw is generally used as a raw material for the production of organic fertilizers. After fermentation, it is formed into mail-in fertilizers that can be used in farmland, thereby achieving the purpose of resource reuse.

[0003] For example, in the patent document that has been made public, announcement number: CN103804053B, a straw organic fertilizer rapid fermentation kettle and a straw organic fertilizer process are disclosed, whose main structure includes a cylindrical kettle body, a heater is arranged under the kettle body, the kettle body is formed by connecting multiple detachable wall panels, and is surrounded by an insulation layer, an insulation cover is arranged on the top of the kettle body, and a kettle bottom is arranged below, an annular sleeve is arranged around the top of the kettle bottom, and the sleeve is matched with the outer periphery of the kettle body, the heater is an underground solar heat storage pool, an insulation layer is arranged around the solar heat storage pool, water is filled in the solar heat storage pool, and a heat dissipation pipe is installed, and both ends of the heat dissipation pipe are connected to the solar collector on the ground, the solar heat storage pool is arranged under the kettle body, and heat conduction pipes are arranged in the solar heat storage pool and the kettle body, and the heat conduction pipes constitute a circulation loop.

[0004] It can be seen from the records of the above-mentioned prior art that the fermentation of organic fertilizer requires sufficient heat, and the organic fertilizer needs aerobic fermentation, which requires the participation of oxygen. Therefore, in the aerobic fermentation of organic fertilizer, it is necessary to aerate the organic fertilizer. In the prior art, the organic fertilizer is directly aerated by a gas supply device, but the initial temperature of the external gas is low, which cannot meet the fermentation temperature of the organic fertilizer.

[0005] The above mainly adopts solar heat storage equipment and straw fermentation heat recovery device, which saves a lot of fuel, ensures heat supply, and reduces fermentation costs. However, the traditional in-kettle treatment method is still used when processing the internal straw. Although energy is saved, the entire fermentation process is relatively slow due to the low initial temperature of the air during the aeration process. The overall fermentation effect is still not obvious, and a lot of heat storage energy is wasted. If the traditional energy-utilizing heating method (electric heating or combustion heating, etc.) is adopted, a lot of energy will be wasted during the fermentation process.

[0006] To this end, the present invention specifically proposes a method for effectively processing waste straw to reduce the energy consumed in the production of organic fertilizers, thereby effectively solving the problems existing in the prior art. Summary of the invention

[0033] (III) Beneficial effects

[0034] Compared with the prior art, the present invention provides a comprehensive production system for producing organic fertilizer by fermentation using waste straw, which has the following beneficial effects:

[0035] 1. The comprehensive production system for fermenting and manufacturing organic fertilizer using waste straw can effectively reduce the loss of hot air around the solar collector by setting a protective cover, and use an air supply device to transport the hot air in the protective cover to the fermentation tank for aerobic fermentation of organic fertilizer. Since hot air is generated around the solar collector, the initial temperature of the air transported from the protective cover to the fermentation tank will be significantly increased, thereby reducing the energy consumption for heating the fermentation tank.

[0036] 2. The integrated production system for producing organic fertilizer by fermentation using waste straw, by arranging a pressure stabilizing chamber and a pressure stabilizing plate at the output end of the air pump, and using the electromagnetic rail in conjunction with the magnetic block and the magnetic isolation layer to control the constant pressure of the pressure stabilizing plate, can ensure that the heated air can be stably transported to the air supply pipe through the pressure stabilizing plate, and then transported to the fermentation tank through the aeration pipe, thereby improving the stability of aeration in the fermentation tank, and thus ensuring the stability of waste straw fermentation.

DETAILED DESCRIPTION

[0059] 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.

[0060] See also Figure 1-16 The present invention discloses a comprehensive production system for producing organic fertilizer by fermenting waste straw, comprising a fermentation tank 1, wherein the fermentation tank 1 is used for stacking waste straw and other materials, wherein the waste straw and other materials are fermented in the fermentation tank 1, and further comprising an air supply device 2 which is connected to the fermentation tank 1 and supplies air to the fermentation tank 1, wherein the air supply device 2 comprises an air supply pipe 3 and an air pump 4 which provides power for gas transportation, wherein the air is transported to the fermentation tank 1 via the air supply device 2 by the air pump 4, and an auxiliary fan 301 may be installed in the air supply pipe 3, and when the gas transportation power in the air supply pipe 3 is insufficient, the auxiliary fan 301 is used to assist gas transportation.

[0061] like Figure 1 As shown in Figure 1 The arrow in the figure indicates the air flow direction, which provides sufficient oxygen for aerobic fermentation of organic fertilizer. One end of the air supply pipe 3 is connected to a protective cover 5, and a solar collector panel 6 is installed inside the protective cover 5. The protective cover 5 is used to reduce the loss of hot air around the solar collector panel 6. The hot air in the protective cover 5 is transported to the fermentation tank 1 by the air supply device 2 for aerobic fermentation of organic fertilizer. Since hot air is generated around the solar collector panel 6, the initial temperature of the air transported from the protective cover 5 to the fermentation tank 1 will be significantly increased, thereby reducing the energy consumption for heating the fermentation tank 1. In addition, during the aeration process, the hot air flows in the organic fertilizer, which not only provides sufficient oxygen for the organic fertilizer, but also makes the organic fertilizer heated more evenly.

[0062] To further explain the principle, organic fertilizer needs aerobic fermentation and the participation of oxygen, so aeration is required in the aerobic fermentation of organic fertilizer. In the prior art, the air supply device 2 is directly used to aerate the organic fertilizer with external air. Since the initial temperature of the external air is low, it cannot meet the fermentation temperature of the organic fertilizer. The present invention uses the protective cover 5 to reduce the loss of hot air around the solar collector 6, utilizes the hot air around the solar collector 6, and increases the initial temperature of the aerated air;

[0063] According to the heat calculation formula Q = cm△t, it is used to calculate the heat absorbed or released by a substance. In this formula:

[0064] Q stands for heat, usually in joules.

[0065] c represents specific heat capacity, that is, the amount of heat absorbed or released when the temperature of a kilogram of a substance rises or falls by 1°C, and the unit is joule / kilogram°C J / kg°C;

[0066] m is the mass of the object, in kilograms;

[0067] △t represents the temperature change of the object, that is, the difference between the final temperature and the initial temperature, and the unit is Celsius °C;

[0068] Therefore, when an object is heated, the temperature of the object rises from t0 to t1, Q = cmt1-t0; since the temperature t1 required for organic fertilizer is constant, the specific heat capacity c of the air and the mass m of the air are also constant, when the initial temperature t0 decreases, the Q generated by heating using the heating device will decrease, thereby reducing energy consumption.

[0069] It should be noted that the air pump 4 is arranged at the air outlet end of the protective cover 5, and a pressure-stabilizing chamber 41 is arranged between the air pump 4 and the air supply pipe 3; a pressure-stabilizing plate 42 is sealingly and slidably installed inside the pressure-stabilizing chamber 41, and a pressure valve is installed on the surface of the pressure-stabilizing plate 42, which is connected to the hose at the upper end of the air supply pipe 3 through the pressure valve.

[0070] An electromagnetic rail 411 is fixedly installed on the inner wall of the voltage stabilizing chamber 41 . Magnetic blocks 421 are provided at both ends of the voltage stabilizing plate 42 . The magnetic blocks 421 are adapted to the electromagnetic rail 411 . Magnetic isolation layers 422 are provided on both sides of the magnetic blocks 421 along the length direction of the electromagnetic rail 411 .

[0071] When the on-current of the electromagnetic rail 411 remains unchanged, since the magnetic isolation layers 422 are provided on both sides of the magnetic block 421, the magnetic force exerted on the magnetic block 421 by the electromagnetic rail 411 is the same at any position on the surface of the electromagnetic rail 411, and thus the force exerted on the voltage stabilizing plate 42 by the magnetic block 421 remains unchanged, so the air pressure inside the pressure stabilizing chamber 41 on the side of the voltage stabilizing plate 42 close to the air pump 4 can remain stable. By designing the pressure valve and cooperating with the electromagnetic rail 411 and the magnetic block 421, the air pressure inside the pressure stabilizing chamber 41 is made higher than the air pressure of the protective cover 5, so that only local gas above the solar collector 6 can effectively enter the pressure stabilizing chamber 41, thereby ensuring that the air above the solar collector 6 enters the pressure stabilizing chamber 41 in a balanced manner. In addition, the gas entering the air supply pipe 3 flows stably to improve the stability of air intake in the fermentation tank 1.

[0072] A heat exchange tube 33 is installed at the bottom of the solar collector 6, and a water pump is used to provide heat exchange medium to the heat exchange tube 33; a trigger device 43 is installed on the outer wall of the pressure stabilizing chamber 41, and a chamber 431, a trigger chamber 1 433 and a trigger chamber 2 434 are arranged inside the trigger device 43, a baffle 435 is arranged between the chamber 431 and the trigger chamber 1 433 and the trigger chamber 2 434, the trigger chamber 2 434 is located on the outer side of the trigger chamber 1 433, and a partition is arranged between the trigger chamber 1 433 and the trigger chamber 2 434. Thermal layer, the interior of the cavity 431 is filled with mercury, and a T-shaped push plate 432 is installed in the interior of the cavity 431 in a sealing and sliding manner. The rod body of the push plate 432 extends to the interior of the pressure stabilizing cavity 41. When the pressure stabilizing plate 42 moves toward the direction of the air supply pipe 3, the pressure stabilizing plate 42 can contact the rod body of the push plate 432. A return spring is provided between the rod body of the push plate 432 and the inner wall of the pressure stabilizing cavity 41. The mercury in the cavity 431 can enter into the trigger cavity 1 433 or the trigger cavity 2 434 through the baffle 435.

[0073] There is a moving contact 4331 slidingly arranged inside the trigger chamber 433 and a fixed contact 4332 fixedly arranged. When the moving contact 4331 contacts the fixed contact 4332 under the push of mercury, the speed of the driving motor of the air pump 4 decreases.

[0074] There is a movable contact 4341 slidably arranged inside the trigger chamber 434 and a fixed contact 4342 fixedly arranged. When the movable contact 4341 contacts the fixed contact 4342 under the push of mercury, the water pump starts.

[0075] The design of the trigger device 43 can ensure the stability of air delivery through the air supply pipe 3 under the premise that the air temperature is within an appropriate range, and avoid excessive pressure inside the pressure stabilizing chamber 41 due to the air pump 4 running too fast. On the other hand, when the air temperature is too high, the water pump can be controlled to start, and the water pump can be used to circulate the heat exchange medium in the heat exchange tube 33 to dissipate heat and cool the solar collector 6, thereby reducing the air temperature and making the air temperature reach an appropriate range.

[0076] A through hole 1 4351 and a through hole 2 4352 are formed on the surface of the blocking piece 435 . The through hole 1 4351 is communicated with the trigger cavity 1 433 , and the through hole 2 4352 is communicated with the trigger cavity 2 434 .

[0077] Two blocks 4353 are radially slidably installed on the surface of the baffle 435 close to the cavity 431, and the radial movement of the block 4353 is used to block the through hole 1 4351 or the through hole 2 4352. The surface of the block 4353 is provided with a single-side expansion heat expansion block 4354, and the heat expansion block 4354 is a heat expansion material. The non-expansion side of the heat expansion block 4354 is fixedly installed on the baffle 435.

[0078] The structural design of the above-mentioned baffle 435 is that when the air temperature is within the appropriate range, the thermal expansion block 4354, due to the telescopic characteristics of the thermal expansion block 4354, the baffle 4353 blocks the second through hole 4352, and the mercury inside the cavity 431 can enter the trigger cavity 1 433 through the through hole 1 4351; when the air temperature is higher than the maximum threshold of the appropriate temperature, the thermal expansion of the thermal expansion block 4354 causes the baffle 4353 to block the first through hole 4351, and the mercury inside the cavity 431 can enter the trigger cavity 2 434 through the through hole 2 4352.

[0079] The moving contact 1 4331 and the moving contact 2 4341 are separated from the corresponding fixed contact 1 4332 and the fixed contact 2 4342 by the negative pressure when the mercury flows back.

[0080] In order to further increase the temperature rise speed of the solar heat collecting panel 6, two embodiments are provided below. The first embodiment is to increase the temperature rise speed by adjusting the angle of the solar heat collecting panel 6 so that the solar heat collecting panel 6 is always directly exposed to sunlight; the second embodiment is to increase the temperature rise speed by adjusting the heated volume of the air;

[0081] The first embodiment, as Figure 6-10 As shown, it also includes an adjusting device for adjusting the inclination angle of the solar thermal collecting panel 6, so that the solar thermal collecting panel 6 changes with the change of the solar altitude angle to increase the heat generated by the solar thermal collecting panel 6.

[0082] The adjusting device includes a supporting device, a tilting connecting device arranged on the top of the supporting device, a mounting plate 22 arranged on the top of the tilting connecting device, and a second telescopic rod 27 providing power for tilting the mounting plate 22;

[0083] The supporting device includes a base 16 and a supporting frame 17 disposed above the base 16;

[0084] The tilting connection device includes an X-axis connection shaft 18 hinged to the support frame 17, a connection arm 19 arranged on the X-axis connection shaft 18, and a Y-axis connection shaft 20 arranged on the connection arm 19;

[0085] The mounting plate 22 and the Y-axis connecting shaft 20 are hinged via a first connecting block 21. A plurality of mounting holes 30 are provided on the mounting plate 22. The mounting plate 22 is used to mount the protective cover 5 and the solar collector plate 6.

[0086] A plurality of second connection blocks 23 are provided on the mounting plate 22, and the second connection blocks 23 and the corresponding second telescopic rods 27 are hingedly connected via a connection member 24, and a first connection shaft 25 hingedly connected to the second connection blocks 23 and a second connection shaft 26 hingedly connected to the second telescopic rod 27 are provided on the connection member 24;

[0087] The bottom of each second telescopic rod 27 is hingedly connected to a mounting seat 28 via a third connecting shaft 29 .

[0088] The above structures cooperate with each other to allow the mounting plate 22 to rotate along the X-axis connecting axis 18 and / or the Y-axis connecting axis 20, so that the angle of the mounting plate 22 can be adjusted. The angle adjustment range of the mounting plate 22 is wide, which makes it easier to make sunlight irradiate the surface of the solar collector 6 more effectively or inefficiently.

[0089] The adjusting device can change the angle of the adjusting device according to the time setting of the controller. The controller controls the extension and retraction of different second telescopic rods 27 to adjust the angle change of the adjusting device, so that the solar collector panel 6 follows the angle of direct sunlight, so that the sunlight directly hits the solar collector panel 6, thereby changing the amount of solar radiation received by the solar collector panel 6, and changing the overall power generation heat and heating speed of the solar collector panel 6.

[0090] The second embodiment, as Figure 10-16 As shown, a partition 10 is provided inside the protective cover 5, and the partition 10 divides the protective cover 5 into a heating chamber 11 close to the solar collector plate 6 and a cavity 12 away from the solar collector plate 6. An adjusting component is also provided on the protective cover 5, and the adjusting component is used to adjust the height of the partition 10. When the height of the partition 10 changes, the thickness of the air in the heating chamber 11 also changes, so as to adjust the volume of the air in the heating chamber 11, thereby adjusting the heating speed of the air in the heating chamber 11.

[0091] An air inlet 7 for air to enter is provided on one side of the protective cover 5 away from the air pump 4. The air inlet 7 is communicated with the heating chamber 11 so that the air can be fully heated in the heating chamber 11. The protective cover 5 is a transparent cover.

[0092] The first option, such as Fig.15 and 16 As shown, the partition 10 is provided with a vent hole 15 for connecting the heating chamber 11 and the cavity 12. The air inlet end of the air pump 4 is connected to the cavity 12 in the protective cover 5. After the height of the partition 10 changes, the thickness of the air in the heating chamber 11 also changes to adjust the volume of the air in the heating chamber 11. The smaller the volume of the air, the faster the air heating rate, and vice versa. Fig.13 As shown in the figure, the rising tip is hot air, and the descending arrow is cold air. After the air is heated, the hot air moves upward in the heating chamber 11, and the cold air moves downward in the heating chamber 11. The air pump 4 works to create negative pressure in the protective cover 5, and the heated air is preferably sucked away from the vent 15, further improving the air heating effect.

[0093] The second option, such as Fig.13 and 14As shown, the partition 10 is a complete plate-shaped setting, and the air inlet end of the air pump 4 is connected to the heating chamber 11 in the protective cover 5. When the height of the partition 10 changes, the thickness of the air in the heating chamber 11 also changes to adjust the volume of the air in the heating chamber 11. The smaller the volume of the air, the faster the air heating rate, and vice versa. The air heating rate is adjusted by adjusting the height of the partition 10.

[0094] The first adjustment method, such as Fig.10 , Fig.12 , Fig.13 and Fig.15 As shown, the adjusting component is an adjusting screw 13, the adjusting screw 13 and the protective cover 5 are connected by threads, the adjusting screw 13 and the partition 10 are rotatably connected, and a screw 31 for rotating the adjusting screw 13 is provided on the adjusting screw 13. The height of the partition 10 can be adjusted by rotating the adjusting screw 13. Manual adjustment is required during operation, and the advantage is low cost.

[0095] The second adjustment method, such as Fig.11 , Fig.14 and Fig.16 As shown, the adjustment component is a first telescopic rod 14, one side of the first telescopic rod 14 is fixedly connected to the protective cover 5, and the telescopic end of the first telescopic rod 14 is fixedly connected to the partition 10. The telescopic movement of the first telescopic rod 14 is controlled to adjust the height of the partition 10, which is more convenient to operate. The partition 10 can be timed controlled by a controller or remotely controlled, which has the advantage of convenient operation.

[0096] The first embodiment and the second embodiment can be implemented separately, or the first embodiment and the second embodiment can be combined and implemented simultaneously to further increase the air heating rate.

[0097] The fermentation tank 1 ferments waste straw and other materials. A feeding device 8 for conveying materials is provided on one side of the fermentation tank 1. The feeding device 8 is used to feed materials into the fermentation tank 1. A discharging device 9 for discharging materials is provided on the other side of the fermentation tank 1. The organic fertilizer in the fermentation tank 1 is discharged by the discharging device 9. Both the feeding device 8 and the discharging device 9 are transmission belts. Several aeration pipes 32 connected to the air supply pipe 3 are provided in the fermentation tank 1. The aeration pipes 32 are used to aerate the fermentation tank 1 to make the aeration of the organic fertilizer more uniform.

[0098] In summary, the integrated production system for producing organic fertilizer by fermentation using waste straw, when in use, uses the feeding device 8 to feed into the fermentation tank 1, waste straw and other materials are piled in the fermentation tank 1 for fermentation, the solar collector 6 heats the air around the solar collector 6 under light, the protective cover 5 covers the outside of the solar collector 6, the protective cover 5 can effectively reduce the loss of hot air around the solar collector 6, and the air supply device 2 is used to transport the hot air in the protective cover 5 to the fermentation tank 1 for aerobic fermentation of the organic fertilizer. Since hot air is generated around the solar collector 6, the initial temperature of the air transported from the protective cover 5 to the fermentation tank 1 will be significantly increased, thereby reducing the energy consumption for heating the fermentation tank 1, and the transported air is aerated through the aeration pipe 32, and the hot air flows fully and evenly in the organic fertilizer, which not only provides sufficient oxygen for the organic fertilizer, but also makes the organic fertilizer heated more evenly, thereby making the fermentation reaction faster and more obvious, and improving the fermentation effect.

[0099] When transporting air, by setting up an air pump 4 and a pressure stabilizing chamber 41, the heated air above the solar collector 6 can enter the pressure stabilizing chamber 41 evenly, and the air can be stably transported in the air supply pipe 3 to improve the stability of the air entering the fermentation tank 1.

[0100] The inclination angle of the solar collector panel 6 is adjusted by the adjusting device, and the controller controls the extension and retraction of different second telescopic rods 27 to adjust the angle change of the adjusting device, so that the solar collector panel 6 follows the angle of direct sunlight, and the sunlight directly hits the solar collector panel 6, thereby increasing the amount of solar radiation received by the solar collector panel 6, and improving the overall power generation heat and heating speed of the solar collector panel 6.

[0101] The height of the partition 10 can also be adjusted by adjusting the assembly, or by manually rotating the adjusting screw 13 to adjust the height of the partition 10, or by controlling the extension and retraction of the first telescopic rod 14 to adjust the height of the partition 10. When the height of the partition 10 changes, the thickness of the air in the heating chamber 11 also changes, so as to adjust the volume of the air in the heating chamber 11, thereby adjusting the heating speed of the air in the heating chamber 11.

[0102] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
