Description

Technical Field

[0001] The invention relates to the field of chemical fertilizers, and in particular to a slow-release fertilizer for flowers and a production device thereof. Background Art

[0002] In urban greening, the cost of urban greening is greatly increased because flowers in one flowering season need to be replaced frequently. Therefore, most of the flowers selected in urban greening are those that bloom continuously. For flowers that bloom continuously, they still need continuous topdressing after flowering, and the amount of topdressing should not be too much each time to avoid burning the root system.

[0003] In the prior art, slow-release fertilizers are usually used to control the time and amount of fertilization. Slow-release fertilizers are usually packaged fertilizers and applied to the fertilization process of flowers with long flowering periods or continuous flowering. However, double-layer packaged fertilizers in the prior art are basically fertilized before flowering, and cannot be fertilized in the soil as base fertilizer before planting. For flowers in urban greening, secondary fertilization cannot be achieved, and the packaged fertilizer can only be applied to the soil as base fertilizer. The outer layer of the packaged fertilizer is only beneficial for fertilization after flowering. Fertilization before flowering will have a negative impact on the flowers. Therefore, designing a slow-release fertilizer suitable for continuously flowering flowers in urban greening has become an urgent problem to be solved. Summary of the invention

[0004] The present invention aims to provide a slow-release fertilizer for flowers and a production device thereof to solve the above problems.

[0005] The present invention is achieved through the following technical solutions: A slow-release fertilizer for flowers, comprising a capsule core, a capsule wall, and a capsule film, wherein the capsule wall wraps the capsule core, wherein the capsule core is made of nitrogen fertilizer, the capsule wall is made of a slow-release phosphate fertilizer mixture, and the capsule film is made of cellulose acetate; The slow-release phosphate fertilizer mixture comprises 20-30 parts of phosphate, 2-5 parts of Aspergillus, 50-70 parts of chitosan solution, 10-15 parts of ethyl cellulose solution, 3-5 parts of hydroxypropyl methylcellulose solution and 200-300 parts of anhydrous ethanol solution.

[0006] The present invention provides a novel slow-release fertilizer, in which phosphate and Aspergillus are added to the capsule wall, so that the phosphate fertilizer is slowly released during the water dissolution of the capsule wall, and the Aspergillus allows the released phosphate to be quickly absorbed by plants, thereby reducing soil pollution and fertility loss. When the capsule wall is released, the nitrogen fertilizer in the capsule core begins to release fertility, and different fertilizers are released in stages, thereby improving the accuracy of release.

[0007] The coating material of the slow-release fertilizer of the present invention is cellulose acetate. Since the cost of fertilizing after flowering in urban green belts is too high, in order to accurately release the slow-release fertilizer, the present invention adds a coating. There are three advantages of choosing cellulose acetate as the coating material. First, when the soil is slightly acidic, it is more conducive to the growth of flowers. Therefore, when the slow-release fertilizer needs to be activated, low-concentration glacial acetic acid can be used to perform artificial irrigation to dissolve the coating and start releasing the slow-release fertilizer.

[0008] Preferably, the thickness of the coating is 0.05-1 mm.

[0009] The physical properties of the coating are stable, so only the dissolution rate needs to be considered. According to the physical properties of the cellulose acetate coating, when the thickness is 0.05-0.1 mm, the integrity of the coating is guaranteed, and the dissolution rate is increased to the greatest extent.

[0010] Preferably, the nitrogen fertilizer is isobutylene diurea.

[0011] Since it is not easy to apply nitrogen fertilizer to flowers that bloom continuously after they bloom, but nitrogen fertilizer needs to be applied after the flowers fall, and the second flowering cycle is longer, the present invention greatly reduces the release rate of nitrogen fertilizer by selecting isobutylene diurea, thereby meeting the fertilization needs of flowers that bloom continuously.

[0012] Preferably, the thickness of the capsule wall is more than twice the diameter of the capsule core.

[0013] Since applying an appropriate amount of phosphate fertilizer to flowers during flowering will prolong the flowering period, the thickness of the capsule wall must be at least twice that of the capsule core to achieve efficient and accurate fertilization for different varieties of flowers.

[0014] A production device for slow-release fertilizer for flowers comprises a capsule wall production module, a capsule core granulation module, a coating module and a film coating module.

[0015] Since the capsule wall thickness of the slow-release fertilizer of the present application is relatively large, the prior art mostly only manufactures capsule walls with thin wall thickness, and therefore the slow-release fertilizer of the present application cannot be effectively produced.

[0016] The coating module includes an installation unit, a spraying unit, and a screening unit. The capsule wall production module is connected to the spraying unit through a pipeline, the capsule core granulation module is connected to the spraying unit through a pipeline, the screening unit is installed and fixed on the spraying unit, and the spraying unit is installed and fixed on the installation unit.

[0017] Since the capsule wall thickness of the slow-release fertilizer of the present invention is relatively large, while the capsule walls of the slow-release fertilizers in the prior art are all thin, the coating module needs to add a screening unit to screen out the fertilizer particles with too small a coating radius to prevent the premature release of nitrogen fertilizer.

[0018] Preferably, the mounting unit includes a mounting rod and a fixed disk, wherein the mounting rod is a slender cylinder, and the fixed disk is a thick flat cylinder, the mounting rod is mounted and fixed on the fixed disk, and the rotating axes of the mounting rod and the fixed disk coincide, and the mounting rod is provided with a mounting portion for installing the spray unit and a mounting portion for installing the encapsulation module.

[0019] The installation unit of the present invention uses a mounting rod in combination with a fixed plate, and a mounting portion of a corresponding unit is provided on the mounting rod. The advantage of such a setting is that the modularization of the production device is realized to the greatest extent. The installation, disassembly, and maintenance of each unit will not affect the other units, thereby reducing the maintenance and replacement costs.

[0020] Preferably, the spraying unit comprises a capsule core feeding pipe, a capsule wall liquid spraying assembly, a high-speed fan, a mounting pipe, and a spraying chamber, wherein the capsule core feeding pipe, the capsule wall liquid spraying assembly, and the high-speed fan are all located above the spraying chamber, the capsule core feeding pipe, the capsule wall liquid spraying assembly, and the high-speed fan are all installed and fixed in the mounting pipe, one end of the mounting pipe is installed and fixed on the mounting rod of the mounting unit, the capsule core feeding pipe, the capsule wall liquid spraying assembly, and the outlets of the high-speed fan are all facing the spraying chamber, the spraying chamber is a hollow sphere, a horizontal section is provided at the upper position of the spraying chamber, and a cover is installed, and the cover is provided with through holes corresponding to the positions of the capsule core feeding pipe, the capsule wall liquid spraying assembly, and the high-speed fan; Since the thickness of the capsule wall is relatively large, the present invention is provided with a high-speed fan to perform preliminary drying during the spraying process to achieve continuous thickening of the capsule wall. The spraying chamber is designed as a hollow sphere, so that the wind of the high-speed fan can move fully in the spraying chamber, and also makes the capsule wall wrap more evenly. In addition, the capsule core feeding pipe, the capsule wall liquid spraying assembly, and the high-speed fan are all fixed on the mounting rod through the mounting tube, so that their relative positions remain fixed.

[0021] Preferably, a screening unit is provided on the outer surface of the spray chamber, the screening unit includes a blanking pipe, a fan, a slide rail, a slider, and a telescopic feed pipe, wherein the cross-sectional shape of the blanking pipe is rectangular, the blanking pipe is movably installed outside the spray chamber through the slide rail and the slider, the height of one end of the blanking pipe is the same as the height of the cover of the spray chamber, and a fan is fixedly installed at this position, the other end of the blanking pipe is fixedly installed with the capsule core feeding pipe through the telescopic feed pipe, a plurality of through holes are provided on the surface where the blanking pipe and the spray chamber are in contact, and through holes with the same diameter as the through holes of the blanking pipe are also provided at corresponding positions of the spray chamber, the spacing between any adjacent through holes on the blanking pipe is greater than the diameter of the through holes, the position of the through holes on the spray chamber corresponds to the position of the through holes of the blanking pipe, a discharge port is provided at the lower end of the spray chamber, and a discharge port is also provided at the corresponding position of the blanking pipe, and the blanking pipe at the discharge port is detachably installed.

[0022] The screening unit of the present invention is arranged on the outer surface of the spray chamber. When the spray unit finishes working, the high-speed fan of the spray unit continues to work, and at the same time, the blanking pipe of the screening unit moves to align the through holes on the spray chamber with the through holes on the blanking pipe. At this time, the fertilizer particles that do not meet the diameter requirements will fall into the blanking pipe. After a certain period of time, the blanking pipe is moved to close the through holes. At this time, the fan of the screening unit starts to work and moves the fertilizer particles in the blanking pipe toward the direction of the telescopic feed pipe until they enter the capsule core feeding pipe.

[0024] The coating module of the present invention comprises a coating chamber, a coating nozzle, an airflow generator and a high-temperature generator, which realizes coating and drying at the same time, and utilizes the airflow generator to make the coating more uniform.

[0025] Preferably, the airflow generator includes a hollow baffle, an air duct, and a wind-generating device, wherein the air duct is a hollow cylinder without a cover and a bottom, wherein the interior of the air duct wall is also hollow, and an air outlet is opened at the upper end of the inner wall of the air duct, and the wind-generating device is installed and fixed on the side of the air duct through a pipeline to press the high-pressure airflow into the wall of the air duct, and the hollow baffle is installed and fixed on the inner side of the air duct, wherein the air duct is installed and fixed on the inner wall of the coating chamber, and the hollow baffle is detachably installed.

[0026] In the present invention, the wind duct is a hollow cylinder without a cover and a bottom. When the coating is completed, it can be directly taken out from the bottom of the wind duct, which simplifies the process. In addition, the interior of the wind duct wall is also hollow, and an air outlet is opened at the upper end of the inner wall of the wind duct, which improves efficiency and saves electricity costs.

[0027] Preferably, the cross-sectional shape of the wall of the air duct is shuttle-shaped, wherein the radius of one end of the wall cross-sectional shape is smaller than the radius of the other end, the wall spacing at the air outlet is 0.05-0.5mm, and the upper surface of the hollow baffle is on the same level as the lower plane of the air outlet.

[0028] Preferably, a ventilation hole is provided below the encapsulation chamber, and a transport device is provided in the ventilation hole.

[0029] In the present invention, a vent is provided below the coating chamber, and a transport device is provided in the vent, which increases the air flow of the air duct by more than 3 times through the Bernoulli principle, so that the coating thickness is more uniform, the drying is faster, and the required drying temperature is lower, thereby improving efficiency and saving electricity costs.

[0030] Preferably, there are at least two coating modules, both of which are mounted and fixed on the fixing plate of the mounting unit, and a rotating device is provided on the mounting rod, so that the spraying unit can rotate with the mounting rod as the rotation axis.

[0031] The number of the film coating modules of the present invention is at least two. Since the number of films cannot be too large during film coating, multiple film coating modules are provided to greatly improve production efficiency.

[0032] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The present invention provides a novel slow-release fertilizer, in which phosphate and Aspergillus are added to the capsule wall, so that the phosphate fertilizer is slowly released during the water dissolution of the capsule wall, and the Aspergillus allows the released phosphate to be quickly absorbed by plants, thereby reducing soil pollution and fertility loss. When the capsule wall is released, the nitrogen fertilizer in the capsule core begins to release fertility, and different fertilizers are released in stages, thereby improving the accuracy of release.

[0033] 2. The coating material of the slow-release fertilizer of the present invention is cellulose acetate. Since the cost of fertilizing after flowering in urban green belts is too high, in order to accurately release the slow-release fertilizer, the present invention adds a coating. There are three advantages of choosing cellulose acetate as the coating material. First, when the soil is slightly acidic, it is more conducive to the growth of flowers. Therefore, when the slow-release fertilizer needs to be activated, low-concentration glacial acetic acid can be used for artificial irrigation to dissolve the coating and start the release of the slow-release fertilizer.

[0034] Preferably, the thickness of the coating is 0.05-1 mm.

[0035] The physical properties of the coating are stable, so only the dissolution rate needs to be considered. According to the physical properties of the cellulose acetate coating, when the thickness is 0.05-0.1 mm, the integrity of the coating is guaranteed, and the dissolution rate is increased to the greatest extent.

[0036] 3. Since it is not easy to apply nitrogen fertilizer to flowers that bloom continuously after they bloom, and nitrogen fertilizer needs to be applied after the flowers fall, and the second flowering cycle is longer, the present invention greatly reduces the release rate of nitrogen fertilizer by selecting isobutylene diurea, thereby meeting the fertilization needs of flowers that bloom continuously.

[0037] 4. Since applying an appropriate amount of phosphate fertilizer to flowers during flowering will prolong the flowering period, the thickness of the capsule wall must be at least twice that of the capsule core to achieve efficient and accurate fertilization for different varieties of flowers.

[0038] 5. The installation unit of the present invention uses a mounting rod in combination with a fixed plate, and a mounting portion of a corresponding unit is provided on the mounting rod. The advantage of such a setting is that the modularization of the production device is realized to the greatest extent. The installation, disassembly, and maintenance of each unit will not affect the other units, thereby reducing the maintenance and replacement costs.

[0039] 6. Since the thickness of the capsule wall is relatively large, the present invention is provided with a high-speed fan to perform preliminary drying during the spraying process to achieve continuous thickening of the capsule wall. The spraying chamber is designed as a hollow sphere so that the wind of the high-speed fan can move fully in the spraying chamber, and also makes the capsule wall wrap more evenly. In addition, the capsule core feeding pipe, the capsule wall liquid spraying assembly, and the high-speed fan are all fixed on the mounting rod through the mounting tube so that their relative positions remain fixed.

[0040] 7. The screening unit of the present invention is arranged on the outer surface of the spray chamber. When the spray unit finishes working, the high-speed fan of the spray unit continues to work, and at the same time, the blanking pipe of the screening unit moves to align the through holes on the spray chamber with the through holes on the blanking pipe. At this time, the fertilizer particles that do not meet the diameter requirements will fall into the blanking pipe. After a certain period of time, the blanking pipe is moved to close the through holes. At this time, the fan of the screening unit starts to work and moves the fertilizer particles in the blanking pipe toward the direction of the telescopic feed pipe until they enter the capsule core feeding pipe.

[0042] 9. In the present invention, the air duct is a hollow cylinder without a cover and a bottom. When the coating is completed, it can be taken out directly from the bottom of the air duct, which simplifies the process. In addition, the interior of the air duct wall is also hollow, and an air outlet is opened at the upper end of the inner wall of the air duct, which improves efficiency and saves electricity costs.

[0052] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0053] Example 1 like Figure 1 As shown, this embodiment includes.

[0054] A slow-release fertilizer for flowers, comprising a capsule core 1, a capsule wall 2, and a capsule film 7, wherein the capsule wall 2 wraps the capsule core 1, wherein the material of the capsule core 1 is nitrogen fertilizer, the material of the capsule wall 2 is a slow-release phosphate fertilizer mixture, and the material of the capsule film 7 is cellulose acetate; The slow-release phosphate fertilizer mixture comprises 20-30 parts of phosphate, 2-5 parts of Aspergillus, 50-70 parts of chitosan solution, 10-15 parts of ethyl cellulose solution, 3-5 parts of hydroxypropyl methylcellulose solution and 200-300 parts of anhydrous ethanol solution.

[0055] The present invention provides a novel slow-release fertilizer, in which phosphate and Aspergillus are added to the capsule wall 2, so that the phosphate fertilizer is slowly released during the water dissolution of the capsule wall 2, and the Aspergillus allows the released phosphate to be quickly absorbed by plants, thereby reducing soil pollution and fertility loss. When the capsule wall 2 is released, the nitrogen fertilizer in the capsule core 1 begins to release fertility, and different fertilizers are released in stages, thereby improving the accuracy of the release.

[0056] The coating 7 material of the slow-release fertilizer of the present invention is cellulose acetate. Since the cost of fertilizing after flowering in urban green belts is too high, in order to accurately release the slow-release fertilizer, the present invention adds a coating 7. There are three advantages of choosing cellulose acetate as the coating 7 material. First, when the soil is slightly acidic, it is more conducive to the growth of flowers. Therefore, when the slow-release fertilizer needs to be activated, low-concentration glacial acetic acid can be used for artificial irrigation to dissolve the coating 7 and start to release the slow-release fertilizer.

[0057] In this embodiment, the thickness of the envelope 7 is 0.05 mm.

[0058] The physical properties of the coating 7 are stable, so only the dissolution rate needs to be considered. According to the physical properties of the cellulose acetate coating 7, when the thickness is 0.05-0.1 mm, the integrity of the coating 7 is guaranteed, and the dissolution rate is increased to the maximum extent.

[0059] In this embodiment, the nitrogen fertilizer is isobutylene diurea.

[0060] Since it is not easy to apply nitrogen fertilizer to flowers that bloom continuously after they bloom, but nitrogen fertilizer needs to be applied after the flowers fall, and the second flowering cycle is longer, the present invention greatly reduces the release rate of nitrogen fertilizer by selecting isobutylene diurea, thereby meeting the fertilization needs of flowers that bloom continuously.

[0061] Preferably, the thickness of the capsule wall 2 is more than twice the diameter of the capsule core 1 .

[0062] Since applying an appropriate amount of phosphate fertilizer to flowers during flowering will prolong the flowering period, the thickness of the capsule wall 2 should be at least twice that of the capsule core 1 to achieve efficient and accurate fertilization for different varieties of flowers.

[0063] Example 2 according to Figure 2-5 As shown, a production device for a slow-release fertilizer for flowers is used to produce a slow-release fertilizer for flowers in Example 1, including a capsule wall 2 production module, a capsule core 1 granulation module, a coating module, and a film coating module 6.

[0064] Since the capsule wall 2 of the slow-release fertilizer of the present application is relatively thick, the prior art mostly only manufactures capsule walls 2 with thin thickness, and therefore the slow-release fertilizer of the present application cannot be effectively produced.

[0065] The coating module includes an installation unit 3, a spraying unit 4, and a screening unit 5. The capsule wall 2 production module is connected to the spraying unit 4 through a pipeline, the capsule core 1 granulation module is connected to the spraying unit 4 through a pipeline, the screening unit 5 is installed and fixed on the spraying unit 4, and the spraying unit 4 is installed and fixed on the installation unit 3.

[0066] Since the capsule wall 2 of the slow-release fertilizer of the present invention is relatively thick, while the capsule wall 2 of the slow-release fertilizer in the prior art is thin, the coating module needs to add a screening unit 5 to screen out the fertilizer particles with too small a coating radius to prevent the nitrogen fertilizer from being released prematurely.

[0067] It can be understood that the capsule core 1 granulation module is prior art.

[0068] Preferably, the mounting unit 3 includes a mounting rod 31 and a fixed disk 32, wherein the mounting rod 31 is a slender cylinder, and the fixed disk 32 is a thick flat cylinder, the mounting rod 31 is installed and fixed on the fixed disk 32, and the rotation axis of the mounting rod 31 coincides with that of the fixed disk 32, and a mounting portion for installing the spray unit 4 and a mounting portion for installing the coating module 6 are provided on the mounting rod 31.

[0069] The installation unit 3 of the present invention uses a mounting rod 31 combined with a fixed plate 32, and a mounting portion of the corresponding unit is provided on the mounting rod 31. The advantage of such a setting is that the modularization of the production device is realized to the greatest extent. The installation, disassembly, and maintenance of each unit will not affect the other units, thereby reducing the maintenance and replacement costs.

[0070] Preferably, the spraying unit 4 includes a capsule core feeding pipe 41, a capsule wall liquid spraying assembly 42, a high-speed fan 43, a mounting pipe 44, and a spraying chamber 45, wherein the capsule core feeding pipe 41, the capsule wall liquid spraying assembly 42, and the high-speed fan 43 are all located above the spraying chamber 45, the capsule core feeding pipe 41, the capsule wall liquid spraying assembly 42, and the high-speed fan 43 are all installed and fixed in the mounting pipe 44, one end of the mounting pipe 44 is installed and fixed on the mounting rod 31 of the mounting unit 3, the capsule core feeding pipe 41, the capsule wall liquid spraying assembly 42, and the high-speed fan 43 are all facing the spraying chamber 45, the spraying chamber 45 is a hollow sphere, a horizontal section is provided at the upper position of the spraying chamber 45, and a cover is installed, and the cover is provided with through holes corresponding to the positions of the capsule core feeding pipe 41, the capsule wall liquid spraying assembly 42, and the high-speed fan 43; It can be understood that the high-speed fan 43 is a prior art.

[0071] Since the thickness of the capsule wall 2 is relatively large, the present invention is provided with a high-speed fan 43 to perform preliminary drying during the spraying process to achieve continuous thickening of the capsule wall 2. The spraying chamber 45 is designed as a hollow sphere, so that the wind of the high-speed fan 43 can move fully in the spraying chamber 45, and also makes the capsule wall 2 wrapped more evenly. In addition, the capsule core feeding pipe 41, the capsule wall liquid spraying assembly 42, and the high-speed fan 43 are all fixed on the mounting rod 31 through the mounting tube 44, so that their relative positions remain fixed.

[0072] Preferably, a screening unit 5 is provided on the outer surface of the spray chamber 45, and the screening unit 5 includes a blanking pipe 51, a fan 52, a slide rail, a slider, and a telescopic feed pipe 53, wherein the pipe cross-section of the blanking pipe 51 is rectangular, and the blanking pipe 51 is movably installed outside the spray chamber 45 through the slide rail slider, and the height of one end of the blanking pipe 51 is the same as the height of the cover of the spray chamber 45, and the fan 52 is fixedly installed at this position, and the other end of the blanking pipe 51 is connected to the capsule core feeding pipe 41 through the telescopic feed pipe 53. The blanking pipe 51 is fixedly installed, and a plurality of through holes are provided on the surface where the blanking pipe 51 and the spray chamber 45 are in contact. A through hole with the same diameter as the through hole of the blanking pipe 51 is also provided at a corresponding position of the spray chamber 45. The spacing between any adjacent through holes on the blanking pipe 51 is greater than the diameter of the through hole. The position of the through hole on the spray chamber 45 corresponds to the position of the through hole of the blanking pipe 51. A discharge port 54 is provided at the lower end of the spray chamber 45, and a discharge port 54 is also provided at a corresponding position of the blanking pipe 51. The blanking pipe 51 at the discharge port 54 is detachably installed.

[0073] It can be understood that the fan 52 in the screening unit 5 and the fan 52 in the spraying unit 4 are both prior art and can share a motor.

[0074] The screening unit 5 of the present invention is arranged on the outer surface of the spraying chamber 45. When the spraying unit 4 finishes working, the high-speed fan 43 of the spraying unit 4 continues to work, and at the same time, the blanking pipe 51 of the screening unit 5 moves to align the through holes on the spraying chamber 45 with the through holes on the blanking pipe 51. At this time, the fertilizer particles that do not meet the diameter requirements will fall into the blanking pipe 51. After a certain period of time, the blanking pipe 51 is moved to close the through holes. At this time, the fan 52 of the screening unit 5 starts to work and moves the fertilizer particles in the blanking pipe 51 toward the telescopic feeding pipe 53 until they enter the capsule core feeding pipe 41.

[0075] It can be understood that the method of moving the blanking pipe 51 through the slider rail is a prior art and there is no unclear issue. In addition, the distance between the blanking pipe 51 and the spray chamber 45 is a reasonable distance in actual use, so there is no unclear issue.
