Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production and processing, in particular to an organic fertilizer for conditioning acidified soil and a preparation device thereof. Background Art

[0002] Fertilizer drying is a method or means used to dry high-humidity fertilizers to a state suitable for storage and transportation. It plays an important role in the fertilizer production process and can improve the quality and yield of fertilizers.

[0003] At present, most of the existing fertilizer granule drying methods adopt a drum type, that is, during the rotation of the drum, heat is transferred to the fertilizer granules through the inner wall of the drum, and the rolling drum can turn the fertilizer granules, thereby completing the drying process.

[0004] However, during the rolling of the drum, the wet fertilizer particles are greatly affected by gravity and still accumulate at the bottom, and the height to which the drum can lift the fertilizer particles is limited during the rotation process, resulting in a smaller turning amplitude. When the fertilizer particles are wet, the fertilizers will stick together and the drum will be lifted lower, making it impossible to dry the fertilizer particles evenly. As a result, there are still some clumped particles inside the dried fertilizer particles, which can easily cause the fertilizer to clump, thus affecting the subsequent use of the fertilizer particles.

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] Embodiment 1:

[0042] See also Figures 1 to 3 as well as Figure 6 , an organic fertilizer preparation device for conditioning acidified soil, comprising a support leg 1, a drying box 2 is fixedly installed on the upper end of the support leg 1, a feed port is opened on the left and right side walls of the drying box 2 near the upper end, a feed plate 21 is fixedly installed at the feed port, a sealing plate 22 is arranged on the inner side of the feed port, the upper end of the sealing plate 22 is hinged to the top of the drying box 2, and an adaptive spring 23 is fixedly installed between the side wall of the sealing plate 22 and the side wall of the drying box 2, a discharge port is opened in the middle of the bottom of the drying box 2, a discharge trough 24 is fixedly arranged at the discharge port, the bottom thickness of the discharge trough 24 gradually decreases from the back to the front, and no less than two air inlet pipes 25 are symmetrically arranged on the lower end surface of the drying box 2, and a spiral feeder 3 is fixedly installed on the side wall of the drying box 2.

[0043] During the specific operation, the external air supply equipment and the air inlet pipe 25 are first connected manually to achieve the purpose of continuously providing hot air, and then the screw feeder 3 is started, and the wet fertilizer particles are manually added to the feeding position of the screw feeder 3, and the wet fertilizer particles are driven by the screw feeder 3 to be transported upward, and finally enter the drying box 2 through the outlet of the screw feeder 3 and the feed plate 21.

[0044] In this embodiment, the sealing plate 22 is provided to prevent the hot air inside the drying box 2 from overflowing from the feed port. At the same time, under the action of the adaptive spring 23, the sealing plate 22 can automatically control the opening angle of the sealing plate 22 according to the amount of feeding, thereby preventing the wet fertilizer particles from clogging the feed port.

[0045] Embodiment 2:

[0046] The technical solution is basically the same as that of the first embodiment, see Figures 3 to 6 The difference is that a drying device 4 is arranged inside the drying box 2, and the drying device 4 includes a material guide plate 41. The material guide plate 41 is symmetrically hinged on the inner side wall of the drying box 2, and a material shaking mechanism 42 is attached under the material guide plate 41. The rear side of the material shaking mechanism 42 is installed on the rear side wall of the drying box 2.

[0047] The material shaking mechanism 42 includes a reciprocating motor 421, which is fixedly installed on the middle part of the rear side wall of the drying box 2 through a motor base, and a driving gear 422 is fixedly provided on the output shaft of the reciprocating motor 421. A gear shaft 423 is installed on the front side of the driving gear 422, and the front end of the gear shaft 423 extends to the inside of the drying box 2. Driven gears 424 are meshed on the left and right sides of the driving gear 422. The driven gear 424 is arranged at the rear end of a transmission shaft 425 by connection. The front end of the transmission shaft 425 is rotated and installed on the front side wall of the drying box 2. A material shaking cam 426 is fixedly provided in the middle part of the transmission shaft 425 inside the drying box 2, and the upper end of the material shaking cam 426 is in contact with the lower side of the proximal end of the material guide plate 41.

[0048] During specific operation, the wet fertilizer particles enter the drying box 2 through the feed port, and then fall onto the guide plate 41 under the action of their own gravity and slide down along the guide plate 41. At this time, the reciprocating motor 421 is started, and the driving gear 422 is driven by the reciprocating motor 421 to reciprocate. Under the action of the driven gear 424, the transmission shaft 425 will also rotate accordingly and drive the shaking cam 426 to reciprocate. The shaking cam 426 squeezes the guide plate 41 and drives the guide plate 41 to reciprocate up and down with its hinge point as the center, thereby driving the wet fertilizer particles on the upper end of the guide plate 41 to shake, and then they are broken into uniform fertilizer particles under the action of the beating rod 554, which is beneficial to improve the drying efficiency of the fertilizer particles.

[0049] A diverter ridge plate 43 is arranged between the two guide plates 41. The front and rear ends of the diverter ridge plate 43 are fixedly mounted on the front and rear side walls of the drying box 2. The upper end of the diverter ridge plate 43 is arc-shaped, and the left and right side walls are convex arc surfaces. The left and right side walls of the diverter ridge plate 43 are made of elastic steel sheets.

[0050] The drying device 4 also includes a drying plate 44, which is symmetrically arranged on both sides of the discharge port at the bottom of the drying box 2. A plurality of ventilation holes are arranged on the drying plate 44. A first spring 45 is symmetrically fixedly installed on the lower end surface of the drying plate 44 close to the end of the drying box 2, and a second spring 46 is symmetrically fixedly installed on the lower end surface of the drying plate 44 away from the end of the drying box 2. The lower end of the first spring 45 and the lower end of the second spring 46 are both fixedly connected to the bottom of the drying plate 44. A feeding mechanism 47 is arranged below the drying plate 44, and the rear side of the feeding mechanism 47 is installed on the front end of the gear shaft 423.

[0051] During specific operation, the broken fertilizer particles continue to move downward under the action of their own gravity, and fall to the left and right sides under the action of the diverter ridge 43. Since the shaking cam 426 intermittently squeezes the left and right side walls of the diverter ridge 43 during the rotation process, causing them to deform, when the shaking cam 426 separates from the diverter ridge 43, its left and right side walls will generate a reset elastic force, which can bounce the fertilizer particles on the left and right surfaces of the diverter ridge 43 onto the drying plate 44. Since a number of ventilation holes are provided on the drying plate 44, the hot air from bottom to top can dry the fertilizer particles on the drying plate 44.

[0052] The unloading mechanism 47 includes an upper pulley 471, an upper pulley 471 is fixedly installed at the front end of the gear shaft 423, a lower pulley 473 is arranged below the upper pulley 471, the lower pulley 473 and the upper pulley 471 are connected by an annular belt 472, the lower pulley 473 is fixedly installed on the pulley shaft 474, the front and rear ends of the pulley shaft 474 are rotatably installed on the front and rear side walls of the drying box 2, a turntable 475 is fixedly arranged in the middle of the pulley shaft 474, and a pull rod 476 is hinged in the middle of the left and right sides of the turntable 475, a rectangular slide is provided at the bottom of the drying box 2 below the drying plate 44, a vertical plate 477 is slidably arranged in the rectangular slide, the end of the pull rod 476 away from the turntable 475 is hinged in the middle of the vertical plate 477, a return spring 478 is arranged between the vertical plate 477 and the side wall of the drying box 2, and a trapezoidal plate 479 is fixedly arranged on the upper end of the vertical plate 477.

[0053] During specific operation, the driving gear 422 will also drive the gear shaft 423 to reciprocate during the reciprocating rotation, thereby driving the upper pulley 471 to reciprocate. Under the action of the annular belt 472, the lower pulley 473 and the pulley shaft 474 will also reciprocate, and the turntable 475 will be driven to reciprocate through the pulley shaft 474. Under the action of the pull rod 476, the vertical plate 477 will reciprocate left and right along the rectangular slide. During this process, the trapezoidal plate 479 will continuously squeeze the drying plate 44. Since the first spring 45 and the second spring 46 are provided at the lower end of the drying plate 44, the drying plate 44 will continuously vibrate up and down, and the fertilizer particles on the drying plate 44 will also vibrate up and down synchronously, so that the fertilizer particles and the hot air are fully in contact, so as to improve the drying efficiency. Finally, the dried fertilizer particles fall down into the discharge chute 24 and slide down from the front end of the discharge chute 24. At this time, the dried fertilizer particles can be collected manually at the front end of the discharge chute 24.

[0054] Embodiment three:

[0055] The technical solution is basically the same as that of the second embodiment, see Figures 1 to 3 as well as Figure 6 and Figure 7 The difference is that a hot air circulation device 5 is provided at the upper end of the drying box 2, and the lower ends of the left and right sides of the hot air circulation device 5 are connected to the inside of the spiral feeder 3.

[0056] The hot air circulation device 5 includes an air storage box 51, which is fixedly installed on the upper end of the drying box 2. The interior of the air storage box 51 is composed of two independent air storage tanks. A dehumidification plate 52 is arranged inside the air storage tank. An air inlet hole 53 is opened at the bottom of the air storage tank. An air collecting hood 54 is installed on the outer side of the lower end of the air inlet hole 53. An air guide duct 56 is connected to the upper end of the air storage box 51, and the lower end of the air guide duct 56 is connected to the interior of the spiral feeder 3 on the corresponding side. The outer side of the air guide duct 56 is coated with an insulation layer, and the insulation layer is composed of foam cotton / fiber cotton / rock wool layer material. A blowing mechanism 55 is arranged in the middle of the air storage box 51, and the lower end of the blowing mechanism 55 extends to the interior of the drying box 2.

[0057] The blowing mechanism 55 includes a blowing motor 551, and the blowing motor 551 is fixedly installed on the upper end of the air storage box 51 through a motor base, and a blowing shaft 552 is fixedly installed on the output shaft of the blowing motor 551, and the lower end of the blowing shaft 552 extends into the interior of the drying box 2 and is fixedly installed with a feeding tray 553, and the feeding tray 553 is evenly provided with feeding rods 554 on the circumferential side walls, and a first pulley 555 is fixedly provided near the upper end of the blowing shaft 552, and second pulleys 556 are symmetrically provided on the left and right sides of the first pulley 555, and the second pulley 556 is connected to the first pulley 555 by a transmission belt 557, and the second pulley 556 is fixedly installed in the middle of the vertical shaft 558, and the upper end of the vertical shaft 558 is rotatably connected to the top of the drying box 2, and the lower end of the vertical shaft 558 is fixedly connected with a blowing blade 559.

[0058] In specific operation, during the drying process, the blower motor 551 is started, and the blower shaft 552 is driven to rotate by the blower motor 551, thereby driving the beating plate 553 and the beating rod 554 to rotate. In the process of the wet fertilizer particles on the upper end of the guide plate 41 shaking up and down, the beating rod 554 can break up the wet fertilizer particles into uniform fertilizer particles. The blower shaft 552 will also drive the first pulley 555 to rotate during the rotation process. Under the action of the transmission belt 557, the second pulley 556, the vertical shaft 558 and the blower blade 559 are also driven to rotate. It will rotate accordingly. The blast blades 559 can increase the rising rate of the hot air in the drying box 2 during the rotation. After the hot air enters the air storage tank inside the air storage box 51 through the air inlet hole 53, the dehumidification plate 52 can absorb the moisture in the hot air, thereby obtaining relatively dry hot air. Subsequently, the dried hot air enters the spiral feeder 3 through the air guide pipe 56. In the process of conveying the wet fertilizer particles upward, the hot air can perform preliminary drying treatment on the fertilizer particles, so that the hot air can be reused for a second time, reducing the drying cost, and being more economical and environmentally friendly.

[0059] It should be noted that, in order to improve the drying efficiency of the fertilizer particles, the guide plate 41, the diversion ridge plate 43 and the drying plate 44 involved in the present invention are all made of heat-conducting materials.

[0060] The present invention also provides an organic fertilizer prepared by an organic fertilizer preparation device for conditioning acidified soil. The organic fertilizer comprises, by percentage of soil mass, 4.0% alkaline additive, 1.5% composite biochar, 1.5% organic fertilizer, and 0.3% microbial preparation. The organic fertilizer is pig manure, and the organic matter content is greater than 55%. The organic fertilizer is continuously vibrated up and down by a drying plate 44, so that the fertilizer particles and the hot air are fully contacted to achieve full drying of the fertilizer.

[0061] The working principle of the present invention when in use:

[0062] First, the external air supply device and the air inlet pipe 25 are manually connected to achieve the purpose of continuously providing hot air, and then the screw feeder 3 is started, and the wet fertilizer particles are manually added to the feeding position of the screw feeder 3, and the wet fertilizer particles are driven by the screw feeder 3 to be transported upward, and finally enter the drying box 2 through the outlet of the screw feeder 3 and the feed plate 21;

[0063] Second, the wet fertilizer particles enter the drying box 2 through the feed inlet, and then fall onto the guide plate 41 under their own gravity and slide down along the guide plate 41. At this time, the reciprocating motor 421 is started, and the driving gear 422 is driven by the reciprocating motor 421 to reciprocate. Under the action of the driven gear 424, the transmission shaft 425 will also rotate and drive the shaking cam 426 to reciprocate. The shaking cam 426 squeezes the guide plate 41 and drives the guide plate 41 to reciprocate up and down with its hinge point as the center, thereby driving the wet fertilizer particles on the upper end of the guide plate 41 to shake, and then they are broken into uniform fertilizer particles under the action of the beating rod 554, which is beneficial to improve the drying efficiency of the fertilizer particles.

[0064] Third, the broken fertilizer particles continue to move downward under the action of their own gravity, and fall to the left and right sides under the action of the diverter ridge plate 43. Since the shaking cam 426 intermittently squeezes the left and right side walls of the diverter ridge plate 43 during the rotation process, thereby deforming them, when the shaking cam 426 is separated from the diverter ridge plate 43, its left and right side walls will generate a restoring elastic force, which can bounce the fertilizer particles on the left and right side surfaces of the diverter ridge plate 43 onto the drying plate 44. Since the drying plate 44 is provided with a plurality of vents, the hot air from bottom to top can dry the fertilizer particles on the drying plate 44.

[0065] Fourth: the driving gear 422 will also drive the gear shaft 423 to reciprocate during the reciprocating rotation, thereby driving the upper pulley 471 to reciprocate. Under the action of the annular belt 472, the lower pulley 473 and the pulley shaft 474 will also reciprocate, and the turntable 475 will be driven to reciprocate through the pulley shaft 474. Under the action of the pull rod 476, the vertical plate 477 will reciprocate left and right along the rectangular slide. During this process, the trapezoidal plate 479 will continuously squeeze the drying plate 44. Since the first spring 45 and the second spring 46 are provided at the lower end of the drying plate 44, the drying plate 44 will continuously reciprocate up and down, and the fertilizer particles on the drying plate 44 will also reciprocate up and down synchronously, so that the fertilizer particles and the hot air are fully in contact, so as to improve the drying efficiency. Finally, the dried fertilizer particles fall down into the discharge trough 24 and slide down from the front end of the discharge trough 24. At this time, the dried fertilizer particles can be collected manually at the front end of the discharge trough 24.

[0066] Five: During the drying process, the blower motor 551 is started, and the blower shaft 552 is driven to rotate by the blower motor 551, thereby driving the beating plate 553 and the beating rod 554 to rotate. During the up and down shaking of the wet fertilizer particles on the upper end of the guide plate 41, the beating rod 554 can break up the wet fertilizer particles into uniform fertilizer particles. During the rotation process, the blower shaft 552 will also drive the first pulley 555 to rotate. Under the action of the transmission belt 557, the second pulley 556, the vertical shaft 558 and the blower blade 559 will also rotate accordingly. The rotation of the blast blades 559 can increase the rising rate of the hot air in the drying box 2 during the rotation process. After the hot air enters the air storage tank inside the air storage box 51 through the air inlet hole 53, the dehumidification plate 52 can absorb the moisture in the hot air, thereby obtaining relatively dry hot air. Subsequently, the dried hot air enters the spiral feeder 3 through the air guide pipe 56. In the process of conveying the wet fertilizer particles upward, the hot air can perform preliminary drying treatment on the fertilizer particles, so that the hot air can be reused for a second time, reducing the drying cost, and being more economical and environmentally friendly.

[0067] One point that needs to be explained is that, in the present invention, in order to improve the efficiency of transporting the hot air inside the air storage box to the inside of the screw feeder, an air pump can be installed on the air guide pipe 56.

[0068] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
