Description

Technical Field

[0001] The present invention relates to the technical field of fertilizer production, and particularly relates to a preparation device and a preparation method for producing a soil acidification improvement fertilizer. Background Art

[0002] Calcium magnesium phosphate fertilizer is a good acid soil conditioner, which can increase the soil pH value, increase the soil salt ion substitution amount and base saturation degree, and supplement Ca and Mg in the soil. It is especially suitable for acidic red soil in the south where calcium and magnesium leaching is relatively serious.

[0003] Calcium magnesium phosphate fertilizer takes phosphate rock, calcium raw materials (such as limestone, dolomite) and magnesium raw materials (such as olivine, serpentine) as main raw materials, and is usually in the form of fine grains or powders of grayish white, brown or grayish green, non-hygroscopic, non-caking, non-toxic and non-corrosive.

[0004] The following problems exist in the prior art:

[0005] 1. During the use of the existing preparation device for producing soil acidification improvement fertilizers, due to the characteristics of calcined ore powder, a catalyst is often used as an auxiliary material for mixing during processing and production to facilitate subsequent extrusion molding. However, directly pouring the catalyst easily causes the surface calcined ore powder to quickly agglomerate, resulting in the inability of the calcined ore powder in deep stirring to be evenly mixed with the catalyst, thus affecting subsequent fertilizer processing.

[0006] 2. During the use of the existing preparation device for producing soil acidification improvement fertilizers, since the catalyst is easily attached to the connecting pipe, it is blocked, resulting in the problem that it is difficult to control the ratio between the calcined ore powder and the catalyst.

[0007] 3. During the use of the existing preparation device for producing soil acidification improvement fertilizers, when stirring the calcined ore powder, some raw materials are easily piled up at the edge, resulting in the problem of uneven mixing of the calcined ore powder.

One end of the top of the preparation main body 1 is fixedly connected to a feed pipe 2, and one end of the top of the preparation main body 1 close to the feed pipe 2 is fixedly connected to a feeding pipe 3. The outer wall of the preparation main body 1 is fixedly connected to a connecting plate 4, the outer wall of the connecting plate 4 is fixedly connected to a discharge bin 5, and one end of the bottom of the connecting plate 4 is fixedly connected to a hydraulic device 6. The middle of the inner wall of the discharge bin 5 is fixedly connected to a vibrating sieve 7, and one end of the bottom of the discharge bin 5 is fixedly connected to a shaping bin 8. The left and right sides of the inner wall of the shaping bin 8 are rotationally connected to electric screw rods 9, and one end of the outer wall of the electric screw rod 9 is threadedly connected to a pushing plate 10. A groove 11 is opened at the center of the bottom of the inner wall of the shaping bin 8. The four corners of the bottom of the shaping bin 8 are fixedly connected to support bases 12, the top of the support base 12 is fixedly connected to a pushing platform 13, and the output end of the pushing platform 13 is slidably connected to the inner wall of the groove 11. The center of the bottom of the outer wall of the preparation main body 1 is fixedly connected to a discharge pipe 14, and an electric valve is fixedly connected to the middle of the outer wall of the discharge pipe 14. The top of the inner wall of the preparation main body 1 is fixedly connected to a support pipe 15, the bottom of the support pipe 15 is fixedly connected to a protective shell 16, and a processing mechanism is arranged on the inner wall of the protective shell 16. The processing mechanism includes a motor 17 fixedly connected to one side of the inner wall of the protective shell 16. The output end of the motor 17 is fixedly connected to a transmission rod 18, and one side of the outer wall of the transmission rod 18 is drivingly connected to a pulley 19. One end of the pulley 19 is drivingly connected to a first gear 20, and both sides of the outer wall of the first gear 20 are rotationally connected to a fixing frame 21, and the top of the fixing frame 21 is fixedly connected to the top of the inner wall of the protective shell 16. The bottom of the first gear 20 is engaged with a first toothed ring 22, and the bottom of the first toothed ring 22 is fixedly connected to a first toothed disc 23. A plurality of limit posts 24 are slidably connected to the top of the first toothed disc 23, and the top of the limit posts 24 is fixedly connected to the top of the inner wall of the protective shell 16. The bottom of the first toothed disc 23 is fixedly connected to a limit frame 25. A distributor 26 is slidably connected to the inner wall of the limit frame 25, and a plurality of stirring blades 27 are fixedly connected to the outer wall of the distributor 26. A discharge port 28 is opened between the stirring blades 27 on the outer wall of the distributor 26.

[0046] During operation, the calcined ore powder (at this time, the calcined ore powder uses phosphate rock, calcium raw materials (such as limestone, dolomite) and magnesium raw materials (such as olivine, serpentine) as the main raw materials) is poured into the preparation main body 1 through the feed pipe 2 arranged at one end of the top of the preparation main body 1. Subsequently, the catalyst (the components of the catalyst here are: mature decomposed organic matter, mineral source humic acid, potassium-solubilizing bacteria and sulfur powder) is poured into the preparation main body 1 through the feeding pipe 3 arranged at one end of the top of the preparation main body 1 near the feed pipe 2. By arranging a support pipe 15 at the top of the inner wall of the preparation main body 1 and a protective shell 16 at the bottom of the support pipe 15, the motor 17 arranged on one side of the inner wall of the protective shell 16 is started, so that the motor 17 drives the transmission rod 18 arranged at the output end to rotate. By arranging a pulley 19 on one side of the outer wall of the transmission rod 18 (the pulley 19 here is composed of a belt and a pulley), the pulley 19 is used to drive the first gear 20 arranged at one end to rotate. By arranging a number of limit posts 24 at the top of the inner wall of the protective shell 16, the limit posts 24 are used to support the first tooth disc 23. Thus, when the first gear 20 rotates, the first tooth ring 22 arranged at the top of the first tooth disc 23 is driven, so that the first tooth disc 23 drives the limit frame 25 arranged at its bottom, and then drives the distributor 26 arranged inside the limit frame 25 to rotate. Since a number of stirring blades 27 are arranged on the outer wall of the distributor 26, and discharge ports 28 are arranged between the stirring blades 27 on the outer wall of the distributor 26, when the stirring blades 27 stir the calcined ore powder, the catalyst enters the distributor 26 along the connecting pipe 31 and is thrown out by the centrifugal force generated by the rotation of the distributor 26. Thus, the calcined ore powder can be fully mixed with the catalyst to form the finished product of calcium magnesium phosphate fertilizer. When the fertilizer mixing is completed, by arranging a discharge pipe 14 at the center of the bottom of the outer wall of the preparation main body 1 and opening the electric valve arranged in the middle of the outer wall of the discharge pipe 14, the fertilizer flows along the discharge pipe 14 and enters the vibrating sieve 7 arranged in the middle of the inner wall of the discharge bin 5. The vibrating sieve 7 is used to break up some agglomerated fertilizers, so that the powdery fertilizer enters the shaping bin 8 arranged at one end of its bottom along the discharge bin 5. At this time, the electric screw rods 9 arranged on the left and right sides of the inner wall of the shaping bin 8 are started, and the electric screw rods 9 are used to drive the pushing plates 10 arranged at one end of the outer wall, so that the fertilizer is evenly filled into the groove 11 arranged at the center of the bottom of the inner wall of the shaping bin 8. By arranging a connecting plate 4 on the outer wall of the preparation main body 1 and a hydraulic device 6 at one end of the bottom of the connecting plate 4, the output end of the hydraulic device 6 moves downward to extrude the fertilizer in the groove 11 to make it shaped. By arranging support bases 12 at the four corners of the bottom of the shaping bin 8 and starting the pushing platform 13 arranged at the top of the support bases 12, the fertilizer particles rolled and shaped in the groove 11 are pushed out of the groove 11. Subsequently, the electric screw rods 9 are started again to drive the pushing plates 10 to push the fertilizer particles out of the shaping bin 8.

[0047] One end of the outer wall of the transmission rod 18 away from the pulley 19 is fixedly connected with a second gear 29. One side of the outer wall of the second gear 29 is meshed with a fixing ring 30, and the inner wall of the fixing ring 30 is fixedly connected with a connecting pipe 31. The bottom of the connecting pipe 31 is fixedly connected with the top of the outer wall of the distributor 26. A protrusion 32 is fixedly connected to the inner wall of the distributor 26, and a knocking rod 33 is rotatably connected to the top of the protrusion 32. The bottom of the feeding pipe 3 is fixedly connected with the top of the protective shell 16. A discharge flexible pipe 34 is fixedly connected to the center of the bottom of the feeding pipe 3, and an electric valve is fixedly connected to the middle of the outer wall of the discharge flexible pipe 34. One end of the discharge flexible pipe 34 is fixedly connected with an adjusting pipe 35, and both sides of the outer wall of the adjusting pipe 35 are rotatably connected to the top of the inner wall of the protective shell 16. One end of the adjusting pipe 35 away from the discharge flexible pipe 34 is fixedly connected with a spring piece 36, and the bottom of the spring piece 36 is lapped with the top of the connecting pipe 31.

[0048] During operation, it is connected by attaching the bottom of the feeding pipe 3 to the top of the protective shell 16, and a discharge hose 34 is provided at the center of the bottom of the feeding pipe 3. During the stirring process of the calcined ore powder, the electric valve provided in the middle of the outer wall of the discharge hose 34 is activated, so that the catalyst in the feeding pipe 3 flows along the adjusting pipe 35 provided at one end of the discharge hose 34 and is discharged into the connecting pipe 31 from the elastic piece 36 provided at the other end of the adjusting pipe 35. By providing the connecting pipe 31 at the top of the distributor 26 and a number of fixing rings 30 are provided on the outer wall of the connecting pipe 31. When the transmission rod 18 rotates, it drives the second gear 29 provided at one end of its outer wall away from the pulley 19, so that the tooth grooves of the second gear 29 are engaged with the outer wall of the fixing ring 30, and the fixing ring 30 is used to push the connecting pipe 31 upward. Thus, when the limiting frame 25 drives the distributor 26 to rotate, the distributor 26 moves vertically in the limiting frame 25, so that the catalyst discharged into the distributor 26 along the connecting pipe 31 can be more evenly mixed with the calcined ore powder. Since the second gear 29 drives the connecting pipe 31 to move upward, the top of the connecting pipe 31 pushes the adjusting pipe 35 to rotate with the connection points on both sides to the inner wall of the protective shell 16 as the fulcrums (the fulcrums where the adjusting pipe 35 is connected to the protective shell 16 have resilience). Thus, part of the catalyst remaining in the discharge hose 34 is affected by the change of the opening of the adjusting pipe 35 and is temporarily stored in the discharge hose 34. When the motor 17 drives the transmission rod 18 to rotate in the reverse direction, the second gear 29 pushes the connecting pipe 31 downward, and the elastic piece 36 at one end of the adjusting pipe 35 loses the limit of the connecting pipe 31, thus restoring the discharge state, avoiding the problem that the catalyst spills during the up and down movement of the connecting pipe 31 and causing pollution inside the equipment. Since the decomposed organic matter in the catalyst is often made from raw materials such as crop straws and animal feces, it is easy for some decomposed organic matter to adhere to the inside of the connecting pipe 31 during the addition process, and over time, the connecting pipe 31 becomes blocked. At this time, by providing a protrusion 32 on the inner wall of the distributor 26 and a knocking rod 33 on the top of the protrusion 32, when the distributor 26 moves up and down during rotation, the knocking rod 33 continuously swings inside the connecting pipe 31 and continuously knocks on the inner wall of the connecting pipe 31, thus shaking off the catalyst adhering to the inside of the connecting pipe 31, further solving the problem that in the use process of the preparation device for fertilizer production, the catalyst is easy to adhere to the connecting pipe 31, resulting in blockage and making it difficult to control the ratio between the calcined ore powder and the catalyst.

[0049] A plurality of second toothed discs 37 are meshed with the outer wall of the first toothed disc 23. The top of the second toothed disc 37 is rotatably connected to the bottom of the outer wall of the protective housing 16, and one end of the bottom of the second toothed disc 37 is fixedly connected to a stirring rod 38. A second toothed ring 39 is meshed with the side of the outer wall of the second toothed disc 37 away from the first toothed disc 23. A plurality of double gears 40 are meshed with the outer wall of the second toothed ring 39, and the top of the double gear 40 is rotatably connected to a fixing block 41. One end of the top of the fixing block 41 is fixedly connected to the bottom of the protective housing 16. A limiting groove 42 is formed at the center of the bottom of the fixing block 41, and a limiting ring 43 is slidably connected to the inner wall of the limiting groove 42. The bottom of the limiting ring 43 is fixedly connected to the top of the second toothed ring 39. A lead screw 44 is fixedly connected to the bottom of the double gear 40, and the bottom of the lead screw 44 is rotatably connected to the bottom of the inner wall of the preparation main body 1. A turning plate 45 is threadedly connected to the bottom of the outer wall of the lead screw 44, and a plurality of linkage gears 46 are rotatably connected to the bottom of the turning plate 45. Sliding grooves 47 are formed on both sides of the outer wall of the lead screw 44, and the inner walls of the sliding grooves 47 are slidably connected to the protrusions in the inner cavities of the linkage gears 46. A pushing ring 48 is meshed with one side of the outer wall of the linkage gear 46, and the top of the pushing ring 48 is rotatably connected to one end of the bottom of the turning plate 45.

[0050] During operation, by arranging a number of second toothed discs 37 on the outer wall of the first toothed disc 23, the first toothed disc 23 is used to drive the second toothed disc 37 arranged with the bottom of the protective shell 16 as the fulcrum to rotate. By arranging a stirring rod 38 at one end of the bottom of the second toothed disc 37, the stirring rod 38 is used to stir the calcined ore powder at the periphery in the preparation main body 1, so as to avoid the problem of uneven stirring. By arranging a second toothed disc 37 on the side of the outer wall of the second toothed disc 37 away from the first toothed disc 23, the second toothed disc 37 drives the second toothed ring 39 to rotate. Since a limiting ring 43 is arranged at the top of the second toothed ring 39, and the top of the limiting ring 43 is embedded in the limiting groove 42 arranged at the center of the bottom of the fixing block 41, the fixing block 41 is used to support the second toothed ring 39. By arranging a double gear 40 at one end of the bottom of the fixing block 41, when the second toothed ring 39 rotates, the double gear 40 is used to drive the lead screw 44 arranged at the bottom to rotate, so as to use the lead screw 44 to control the material turning disc 45 arranged at the bottom of its outer wall to move up and down in the preparation main body 1. Not only the material turning disc 45 is used to clean the joint surface of the inner wall of the preparation main body 1, but also the calcined ore powder accumulated at the edge of the preparation main body 1 can be pushed back to the center, making the mixing more uniform. By arranging a number of linkage gears 46 at the bottom of the material turning disc 45, the protrusions in the inner cavity of the linkage gears 46 slide in the sliding grooves 47 arranged on both sides of the outer wall of the lead screw 44. When the lead screw 44 drives the linkage gears 46 to rotate, by arranging a material pushing ring 48 at one end of the bottom of the material turning disc 45, the linkage gears 46 are used to drive the material pushing ring 48 to rotate, so that the material pushing ring 48 pushes out the calcined ore powder accumulated at its bottom, avoiding the problem that during the process of the lead screw 44 driving the material turning disc 45 to descend, due to the accumulation of the calcined ore powder, the descending resistance is large, resulting in damage to the internal parts of the equipment.

Then, feed 0.8 part of potassium-solubilizing bacteria and 1.5 parts of sulfur powder into the preparation main body 1 through the feeding pipe 3. Control the humidity at 50%-60% and the temperature at 45-55°C, and ferment for 5 days. During this period, start the processing mechanism once a day for turning the pile to ensure uniform decomposition;

[0057] S3: After fermentation, dry the fertilizer until the water content is <15%. Open the discharge pipe 14, send the fertilizer particles into the vibrating sieve 7, and then enter the shaping bin 8 along the discharge bin 5 for rolling and shaping.

[0058] Next, specifically describe the working principle of the preparation equipment and its preparation method for the soil acidification improvement fertilizer.

[0059] As Figures 1 - 12As shown, the calcined ore powder is poured into the preparation main body 1 through the feed pipe 2 arranged at one end of the top of the preparation main body 1. Subsequently, the catalyst is poured into the preparation main body 1 through the feeding pipe 3 arranged at one end of the top of the preparation main body 1 close to the feed pipe 2. By arranging a support pipe 15 at the top of the inner wall of the preparation main body 1 and a protective shell 16 at the bottom of the support pipe 15, the motor 17 arranged on one side of the inner wall of the protective shell 16 is started, so that the motor 17 drives the transmission rod 18 arranged at the output end to rotate. By arranging a pulley 19 on one side of the outer wall of the transmission rod 18 (here the pulley 19 is composed of a belt and a pulley), the pulley 19 drives the first gear 20 arranged at one end to rotate. By arranging a plurality of limit posts 24 at the top of the inner wall of the protective shell 16, the limit posts 24 are used to support the first tooth disc 23. Thus, when the first gear 20 rotates, it drives the first tooth ring 22 arranged at the top of the first tooth disc 23, so that the first tooth disc 23 drives the limit frame 25 arranged at its bottom, and then drives the distributor 26 arranged inside the limit frame 25 to rotate. Since a plurality of stirring blades 27 are arranged on the outer wall of the distributor 26, and discharge ports 28 are arranged between the stirring blades 27 on the outer wall of the distributor 26, when the stirring blades 27 stir the calcined ore powder, the catalyst enters the distributor 26 along the connecting pipe 31 and is thrown out by the centrifugal force generated by the rotation of the distributor 26. Thus, the calcined ore powder can be fully mixed with the catalyst. By arranging a plurality of second tooth discs 37 on the outer wall of the first tooth disc 23, the first tooth disc 23 drives the second tooth disc 37 arranged with the bottom of the protective shell 16 as a fulcrum to rotate. By arranging a stirring rod 38 at one end of the bottom of the second tooth disc 37, the stirring rod 38 is used to stir the calcined ore powder at the periphery in the preparation main body 1 to avoid the problem of uneven stirring. When the fertilizer finished product is obtained by mixing the calcined ore powder and the catalyst, by arranging a discharge pipe 14 at the center of the bottom of the outer wall of the preparation main body 1 and opening the electric valve arranged in the middle of the outer wall of the discharge pipe 14, the fertilizer flows along the discharge pipe 14 and is discharged into the vibrating sieve 7 arranged in the middle of the inner wall of the discharge bin 5. The vibrating sieve 7 is used to break up some agglomerated fertilizers, so that the powdery fertilizers enter the shaping bin 8 arranged at one end of the bottom of the discharge bin 5. At this time, the electric screw rods 9 arranged on the left and right sides of the inner wall of the shaping bin 8 are started, and the electric screw rods 9 drive the pushing plates 10 arranged at one end of the outer wall, so that the fertilizers are evenly filled into the groove 11 arranged at the center of the bottom of the inner wall of the shaping bin 8. By arranging a connecting plate 4 on the outer wall of the preparation main body 1 and a hydraulic device 6 at one end of the bottom of the connecting plate 4, the output end of the hydraulic device 6 moves downward to extrude the fertilizers in the groove 11 to form them. By arranging support bases 12 at the four corners of the bottom of the shaping bin 8 and starting the pushing platform 13 arranged on the top of the support bases 12, the fertilizer particles formed by rolling in the groove 11 are pushed out of the groove 11. Then, the electric screw rods 9 are started again to drive the pushing plates 10 to push the fertilizer particles out of the shaping bin 8.

[0060] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present invention are within the protection scope of the present invention.
