Description

Technical Field

[0001] The present application relates to the technical field of film coating machines, and in particular to a film coating machine for compound fertilizer production. Background Art

[0002] With the development of agricultural industrialization, manual fertilization is becoming more costly and inefficient. Drones or simultaneous seeding and fertilizer application will inevitably replace manual labor. Automated fertilization places higher demands on the looseness of compound fertilizers. Compound fertilizer consumption is seasonal, and the storage time of compound fertilizers is increasing, placing higher demands on fertilizer anti-caking technology.

[0003] Fertilizer caking can be caused by many factors. Because fertilizer is hygroscopic, caking is more severe in hot and humid seasons. It can also clump in the cooler winter, but is less likely to clump in spring and autumn. Caking is a widespread problem in the fertilizer industry, impacting both the company's image and user experience. Therefore, finding better and more cost-effective methods to prevent fertilizer caking is crucial.

[0004] At present, the commonly used method is to wrap anti-caking oil or anti-caking powder on the surface of compound fertilizer, using coating technology, and the commonly used equipment for coating is a coating machine. The existing coating machine equipment adopts roller coating, and a plurality of annular tracks are provided on the outer wall of the drum to drive the drum to rotate through gear meshing. The feed port and discharge port of the drum coating machine are respectively arranged at both ends of the drum. For example, a slow-release fertilizer coating device disclosed in Chinese utility model patent 202122340850.4 includes a drum, a feeding device and a discharging device respectively arranged at both ends of the drum, and an inner liner layer is provided on the inner wall of the drum. The device disclosed in the patent can make the coating agent and the powder fertilizer fully contact, so that the particles are fully coated. With the help of the inner wall of the liner layer, the coated particles have a good shape and high consistency in shape. The device is provided with a bracket on the feed bin, and a plurality of powder coating agent feeding screw devices are installed on the bracket. The feeding screw device is used to evenly distribute the fed powder.

[0005] Considering that the coating agent is a powder, it is difficult to fully disperse the coating agent by simply setting a feeding screw device on the feed bin, and it is even more difficult to evenly wrap the coating agent on the surface of the compound fertilizer particles in the subsequent process. Therefore, it is necessary to improve the existing coating machine to meet actual production needs. Summary of the Invention

[0006] The present application proposes a coating machine for compound fertilizer production to solve the problems that existing devices are difficult to fully disperse the coating agent and are even more difficult to evenly coat the coating agent on the surface of compound fertilizer particles in subsequent processes.

[0007] In order to solve the above technical problems, the present application proposes a coating machine for compound fertilizer production, which includes a feed funnel, a roller, a discharge bin and a driving device.

The variable frequency motor is arranged above the distribution disc, and the variable frequency motor and the connecting part are connected through the connecting bolts. The variable frequency speed regulation motor is used to drive the rotation of the distribution disc and control the rotation speed of the distribution disc. A locking stop nut is provided at the center position of the distribution disc.

[0011] Wherein, the angle between the inclined surface of the downward-throwing distribution plate and the horizontal plane is 0-15 degrees.

[0012] Wherein, the angle between the inclined surface of the upward-rising distribution plate and the horizontal plane is 0-15 degrees.

[0013] Wherein, the surface of the distribution tray is provided with distribution plates, and the number of the distribution plates is 4-16 pieces.

DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0026] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of a film coating machine for compound fertilizer production of the present application.

[0028] The coating machine 1 for compound fertilizer production shown in this embodiment includes a feed funnel 2, a roller 3, a discharge bin 4 and a driving device 5. The feed funnel 2 and the discharge bin 4 are arranged on both sides of the roller 3, and the driving device 5 is arranged below the roller 3. The driving device 5 includes a first driving motor 51, a driving gear 52 and a roller 53. A gear ring 54 and a track ring 55 that cooperate with the driving motor and the roller 53 are provided on the outside of the roller 3. The driving device 5 is used to drive the rotation of the roller 3, and the roller 3 is driven to rotate by meshing the driving gear 52 with the gear ring 54. The number of the track rings 55 is at least two, and the track ring 55 is supported on the roller 53 to keep the roller 3 balanced during rotation.

[0029] The inside of the drum 3 is provided with a distributor 6 for dispersing the coating agent. The distributor 6 is used to disperse the coating agent that wraps the compound fertilizer. By arranging the distributor 6 inside the drum 3 instead of at the feed funnel 2, it can be ensured that after the compound fertilizer enters the drum 3, the coating agent is evenly dispersed and transported through the distributor 6, and the compound fertilizer is further coated. The coating agent in this embodiment is anti-caking powder. By evenly wrapping the anti-caking powder on the surface of the compound fertilizer, the fertilizer can be effectively prevented from agglomerating.

[0030] Combine Figure 2 As shown, Figure 2 Figure 6 is a schematic diagram of the structure of the distributor 6. A coating agent feeding device 7 is located above the distributor 6. The coating agent feeding device 7 includes a coating agent conveying roller 71 and a coating agent feed port 72. The coating agent feed port 72 is located above the coating agent conveying roller 71. A second drive motor 73 is provided at one end of the coating agent conveying roller 71. The coating agent feeding device 7 is a feed hopper, and the coating agent conveying roller 71 is a spiral feed device. The second drive motor 73 drives the spiral rotation of the coating agent conveying roller 71, thereby conveying the anti-caking powder to the distributor 6.

[0031] Furthermore, the distributor 6 is a disc distributor 6, which includes a variable frequency speed regulation motor 61, a connecting bolt 62, a connecting piece 63 and a distribution disc 64. The variable frequency speed regulation motor 61 is arranged above the distribution disc 64, and the variable frequency speed regulation motor 61 and the connecting piece 63 are connected through the connecting bolt 62. The variable frequency speed regulation motor 61 is used to drive the rotation of the distribution disc 64 and control the rotation speed of the distribution disc 64. A locking stop nut 65 is provided at the center position of the distribution disc 64.

[0032] By arranging the disc distributor 6 inside the drum 3 and controlling the speed of the disc distributor 6 by the variable frequency speed regulating motor 61, the anti-caking powder enters the drum 3 through the coating agent feeding device 7, is evenly dispersed by the disc distributor 6, and is evenly coated on the surface of the compound fertilizer.

[0033] Further integration Figure 3 and Figure 4 As shown, the distribution plate 64 is one of a flat distribution plate 64, a downward-throwing distribution plate 64 and an upward-throwing distribution plate 64, wherein the flat distribution plate 64 is parallel to the horizontal plane, and when the variable frequency speed regulating motor 61 drives the distribution plate 64 to rotate, the anti-caking powder above the distribution plate 64 is thrown out horizontally; Figure 3 As shown, the downward-throwing feeding tray 64 is tilted downward relative to the horizontal plane. When the variable frequency speed regulating motor 61 drives the feeding tray 64 to rotate, the anti-caking powder above the feeding tray 64 is diffused outward by the centrifugal force and thrown downward at the same time; Figure 4 As shown, the upward-type distribution plate 64 is inclined upward relative to the horizontal plane. When the variable frequency speed regulation motor 61 drives the distribution plate 64 to rotate, the anti-caking powder above the distribution plate 64 is diffused outward by the centrifugal force and is first thrown upward, and then moves downward due to the action of gravity.

[0034] In this embodiment, the adjustment range of the variable frequency speed regulation motor 61 is 0-150r / min, and the diameter d2 of the distribution plate 64 is 0.2-0.6 meters. If the diameter of the distribution plate 64 is too small, the amount of anti-caking powder above the distribution plate 64 will be too small, and it will be difficult to evenly disperse the anti-caking powder through the distribution plate 64. If the diameter of the distribution plate 64 is too large, a large amount of anti-caking powder will accumulate above the distribution plate 64, and it will be difficult to fall down. Therefore, in this application, the diameter of the distribution plate 64 is set to 0.2-0.6 meters.

[0035] It should be further noted that the angle α1 between the inclined surface of the downward-throwing distribution disc 64 and the horizontal plane is 0-15 degrees, while the angle α2 between the inclined surface of the upward-throwing distribution disc 64 and the horizontal plane is 0-15 degrees. This design further regulates the rotation speed of the distribution disc 64 and controls the spray diameter of the anti-caking powder above the distribution disc 64. In this embodiment, the spray diameter d1 is 500-650 mm.

[0036] The surface of the distribution plate 64 is provided with distribution plates 641, and the number of the distribution plates 641 is 4-16. Figure 5 As shown, the cloth plate 641 is either straight or curved. Figure 5 In the figure a, the surface of the distribution plate 64 is smooth, and no distribution plate 641 is provided on the surface of the distribution plate; Figure 5 b is a spraying type, and an involute linear distribution plate 641 is provided on the surface of the distribution plate 64; Figure 5 The c in the figure is a lifting type, and an arc-shaped distributing plate 641 is provided on the surface of the distributing plate 641. In actual production, different types of distributing plates 641 can be selected according to the actual needs of dispersing the anti-caking powder.

[0037] The distribution plate 64 in this embodiment can prevent the anti-caking powder from scattering and unevenly distributing when rolling in the drum 3, effectively improving the utilization rate of the anti-caking powder and enhancing the coating processing efficiency of the compound fertilizer.

[0038] Further references Figure 1 In the coating machine 1 for compound fertilizer production provided in this application, an oil spray pipe 8 is provided in the drum 3, and a nozzle 9 is provided at one end of the oil spray pipe 8. The oil spray pipe 8 is used to spray the anti-caking oil agent. The oil spray pipe 8 is provided on a side close to the feed funnel 2. The distributor 6 is provided on a side close to the discharge bin 4, and the distance between the distributor 6 and the oil spray pipe 8 is 0.8-1.5 meters.

[0039] If the distance between the distributor 6 and the oil injection pipe 8 is set too close, the anti-caking oil agent sprayed from the nozzle 9 of the oil injection pipe 8 does not completely wrap the compound fertilizer, and the addition of the anti-caking powder will affect the continuity of the wrapping; if the distance between the distributor 6 and the oil injection pipe 8 is set too far, the anti-caking oil agent on the surface of the compound fertilizer does not have good viscosity when it drops to a certain temperature, and the anti-caking powder cannot be fixed on the surface of the compound fertilizer, resulting in a reduced utilization rate of the anti-caking powder.

[0040] The present application uses the distributor 6 to evenly disperse the coating agent, thereby preventing the compound fertilizers from sticking to each other, improving the processing speed of the compound fertilizers, and the processed compound fertilizers have good anti-caking effect.
