Description

Technical Field

[0001] This invention relates to the field of fertilizer processing technology, specifically to a fertilizer production device. Background Technology

[0002] Chemical fertilizers are mineral fertilizers containing essential plant nutrients such as nitrogen, phosphorus, and potassium, produced through chemical or physical methods. They mainly include nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, compound fertilizers, and micronutrient fertilizers. In fertilizer production, a rotary drum granulator is used to granulate the raw materials.

[0003] A search revealed Chinese invention patent application number CN202323137063.5, which discloses a rotary drum granulator for fertilizer production, comprising a rotary drum granulator, a disassembly assembly, and a locking assembly. The rotary drum granulator described above, with three sets of first, second, and third inner cylinders arranged between the upper and lower binding grooves within the granulator, can be easily disassembled after use. This allows for thorough and uniform cleaning or replacement of damaged parts of the three sets of inner cylinders, improving the convenience of cleaning and replacement. Furthermore, after installation, the first, second, and third inner cylinders are secured by locking blocks within the mounting boxes on one side of the granulator, achieving quick and easy fixation, thus improving the convenience of disassembly and assembly and ensuring stability after installation.

[0004] In the aforementioned device, the rollers are tilted at a fixed angle during production. Therefore, it cannot adapt to the ideal residence time of different materials during production, which will result in some raw materials failing to meet the production specifications. Furthermore, when cleaning impurities inside the inner cylinder, it is necessary to disassemble the first, second, and third inner cylinders, making the cleaning process time-consuming and labor-intensive. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a fertilizer production device that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fertilizer production device, comprising a drum and a base plate disposed below the drum, wherein a plurality of limiting wheels and driven gears are disposed on the outer wall of the drum, and a driving unit is disposed on the base plate to drive the drum to rotate. It also includes a chassis, with the base plate located on top of the chassis. The chassis is equipped with an adjustment mechanism for adjusting the tilt angle between the roller axis and the ground. A detachable cleaning component is also provided on one side of the chassis to scrape off the deposits on the inner wall of the roller. The adjustment mechanism includes an adjustment section and a support shaft. The adjustment section consists of two cylinders, which are respectively located on the bottom sides of the base plate. The piston rod ends of the cylinders are hinged to the bottom of the base plate. The support shaft is a shaft whose length can be changed, with one end fixed to the bottom of the chassis and the other end abutting against the base plate.

[0007] Preferably, each cylinder has a first rotating groove at the end of its piston rod, a first rotating rod is rotatably connected to the first rotating groove, and a movable shaft is fixedly connected to the rod body of the first rotating rod.

[0008] Preferably, the bottom of the base plate is provided with a second rotating groove, the first rotating rod abuts against the second rotating groove, and both ends of the first rotating rod extend and are fixed on the inner wall of the second rotating groove.

[0009] Preferably, the support shaft includes a support rod, a spring, and a sleeve. The sleeve is fixed to the bottom wall of the chassis, the support rod is slidably connected inside the sleeve, one end of the spring is fixed to the bottom of the inner wall of the sleeve, and the other end is fixed to the top of the support rod. The top of the support rod has a support ball, and the bottom of the base plate has several slots, with each support ball corresponding to and abutting against one of the slots.

[0010] Preferably, the drive unit includes a motor, a reducer, and a drive gear. The motor and the reducer are both fixed on the base plate. The output shaft of the motor is fixedly connected to the input shaft of the reducer. The output shaft of the reducer is fixedly connected to the drive gear, and the drive gear meshes with the driven gear.

[0011] Preferably, the side wall of the machine housing located at the discharge end of the drum is also equipped with a discharge ramp, and an electronic level is also installed on the base plate.

[0012] Preferably, the cleaning assembly includes a mounting bracket fixed to the side wall of the chassis, the mounting bracket being positioned on the side of the chassis away from the unloading ramp, and a second rotating rod rotatably connected to the upper end of the mounting bracket, with an inclined plate fixedly connected to the second rotating rod. Preferably, a torsion spring is installed at the junction of the second rotating rod and the mounting bracket, a connecting shaft is fixedly connected to the inclined plate, a scraper is detachably connected to the connecting shaft, and a fixing member is provided between the connecting shaft and the scraper to fix the scraper and the connecting shaft.

[0013] Preferably, the base plate is also equipped with several brackets, each bracket is equipped with an auxiliary wheel, and the limiting wheel is provided with a groove, the auxiliary wheel and the groove cooperate with each other.

[0014] Compared with existing technologies, this fertilizer production device has the following advantages: 1. The piston rod end of the cylinder is rotatably connected to the second rotating groove, thereby rotatably connecting the piston tube end of the cylinder to the bottom of the base plate. When adjusting the tilt angle of the roller, the height of one end of the cylinder piston tube needs to be raised, while the height of the other end is lowered. A certain gap is left between the opening on the machine box and the base plate for adjusting the tilt angle of the base plate. An electronic level is also installed on the base plate to monitor the angle of the base plate at all times. When the tilt angle reaches the specified angle, the operation of the cylinder stops. Adaptive adjustment ensures that each material is granulated under optimal conditions, improving the granulation rate. At the same time, the equipment reduces energy consumption and return rate, and improves production efficiency.

[0015] Second, the inclined plate is hinged to the mounting frame via a second rotating rod, and the preload of the torsion spring ensures that the connected scraper rod is always adaptively pressed against the inner wall of the drum. For better drum cleaning, the drum can be tilted at a certain angle, allowing the scraped material to flow out with the water from the discharge ramp, thus efficiently removing residual material. The scraper rod is detachably connected via a coupling and fixing parts; this modular design greatly facilitates the replacement of easily worn parts. To further improve the reliability of the equipment, this invention also includes an auxiliary limiting system, where an auxiliary wheel mounted on the base plate bracket engages with the groove of the upper limit wheel on the drum. This convex-concave mechanical structure effectively counteracts the axial force generated during drum operation, preventing drum slippage and ensuring smooth operation.

[0016] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1

[0020] Please see Figures 1 to 7 A fertilizer production device includes a drum 1 and a base plate 2 disposed below the drum 1. The outer wall of the drum 1 is provided with a plurality of limiting wheels 101 and driven gears 102. The base plate 2 is provided with a driving unit 5, which drives the drum 1 to rotate. The drum 1 is filled with material. The driving unit 5 rotates the drum 1. By using a certain amount of water or steam, the material particles are squeezed together and agglomerated into balls under the continuous rotation of the drum 1, achieving the technical effect of material granulation. It also includes a housing 3, with the base plate 2 positioned above the housing 3. The housing 3 is equipped with an adjustment mechanism 10 for adjusting the tilt angle between the axis of the roller 1 and the ground. A detachable cleaning component 8 is also provided on one side of the housing 3 to scrape off the deposits on the inner wall of the roller 1, adjust the tilt angle of the base plate 2, thereby adjusting the angle of the roller 1, and clean the inside of the roller wall after processing using the cleaning component 8. The adjustment mechanism 10 includes an adjustment part 1001 and a support shaft 1002. The adjustment part 1001 consists of two cylinders 1003, which are respectively disposed on both sides of the bottom of the base plate 2. The piston rod ends of the cylinders 1003 are hinged to the bottom of the base plate 2. The support shaft 1002 is a shaft whose length can be changed. One end of the shaft is fixed to the bottom of the housing 3, and the other end abuts against the base plate 2. Each piston rod end of the cylinder 1003 has a first rotating groove 1004. A first rotating rod 1007 is rotatably connected to the first rotating groove 1004. A movable shaft 1006 is fixedly connected to the rod of the first rotating rod 1007. A second rotating groove 1005 is provided at the bottom of the base plate 2. 7 abuts against the second rotating groove 1005, and both ends of the first rotating rod 1007 extend and are fixed on the inner wall of the second rotating groove 1005. Through the above structure, the piston rod end of the cylinder 1003 is rotatably connected to the second rotating groove 1005, so that the piston tube end of the cylinder 1003 is rotatably connected to the bottom of the base plate 2. When adjusting the tilt angle of the roller 1, it is necessary to raise the height of the piston tube of one end of the cylinder 1003 and lower the height of the other end. A certain gap is left between the opening on the machine box 3 and the base plate 2 for adjusting the tilt angle of the base plate 2. An electronic level 9 is also installed on the base plate 2 to monitor the angle of the base plate 2 at all times (the axis of the base plate 2 is parallel to the axis of the roller 1). When the tilt angle reaches the specified angle, the operation of the cylinder 1003 is stopped.

[0021] In this embodiment, to further increase the supporting force under the base plate 2 and improve the stability when changing its tilt angle, the support shaft 1002 includes a support rod 1008, a spring 1009, and a sleeve 1010. The sleeve 1010 is fixed to the bottom wall of the housing 3. The support rod 1008 is slidably connected inside the sleeve 1010. One end of the spring 1009 is fixed to the bottom of the inner wall of the sleeve 1010, and the other end is fixed to the top of the support rod 1008. The top of the support rod 1008 has a support ball 1011. The bottom of the base plate 2 has several slots 1012. Each support ball 1011 abuts against one of the slots 1012. The support rod 1008 is used to share the supporting force received by the cylinder 1003. The internal spring 1009 is in a compressed state. When the base plate 2 is tilted, one side is off the ground. As the distance increases, the support rod 1008 also rises, pressing against the lower part of the base plate 2. The other support rod 1008 is compressed downwards, and the pressure of the spring 1009 is converted into a supporting force on the bottom of the base plate 2, ensuring its stability when the base plate is tilted. Furthermore, a limit shaft is rotatably connected between the center of the base plate 2 and the side wall of the machine casing 3 to ensure that the base plate 2 rotates around the center point when it receives the force of the cylinder 1003. Different tilt angles are set according to different types of raw materials. For example, when processing high-moisture phosphogypsum, the system automatically adjusts the tilt angle to 5° and extends the residence time to 20 minutes; when processing dry organic fertilizer, the tilt angle is increased to 10° and the residence time is shortened to 10 minutes. This adaptive adjustment ensures that each material is granulated under optimal conditions, with a granulation rate of 85%. At the same time, the equipment reduces energy consumption and return rate, and improves production efficiency. Example 2

[0022] Based on the above embodiments, to ensure stable rotation of the drum 1, the drive unit 5 in this embodiment adopts a modular design of "motor 501 + reducer 502 + gear transmission". The design of the motor 501 and reducer 502 being fixed together to the base plate 2 forms a stable power base, effectively absorbing vibrations and reaction forces during operation. The meshing method between the drive gear 503 and the driven gear of the drum has higher transmission efficiency and torque carrying capacity compared to direct drive or belt drive, making it particularly suitable for heavy-duty, continuous working scenarios such as drum granulators. The discharge ramp 4 located at the discharge end ensures that the granular material can be smoothly and centrally discharged, avoiding accumulation. The introduction of the electronic level 9 is a key design feature of this embodiment. It enables quantitative monitoring of the equipment's level status, because the drum's inclination angle directly affects the material's residence time and granulation effect; precise leveling is a prerequisite for ensuring process repeatability and product quality. Example 3

[0023] In this embodiment, to facilitate cleaning the inner wall of the drum 1, the cleaning assembly 8 includes a mounting bracket 801 fixed to the side wall of the housing 3. The mounting bracket 801 is located on the side of the housing 3 away from the discharge ramp 4. A second rotating rod 803 is rotatably connected to the upper end of the mounting bracket 801. An inclined plate 802 is fixedly connected to the second rotating rod 803. A torsion spring 804 is installed at the junction of the second rotating rod 803 and the mounting bracket 801. A connecting shaft 805 is fixedly connected to the inclined plate 802. A scraper 806 is detachably connected to the connecting shaft 805. A fixing member 807 is provided between the connecting shaft 805 and the scraper 806 to fix the scraper 806 and the connecting shaft 805. In this embodiment, the mounting bracket 801 of the cleaning assembly 8 is located on the side of the housing 3 away from the discharge ramp 4 to avoid interfering with the normal discharge of materials. The inclined plate 802 is hinged to the mounting frame 801 via the second rotating rod 803, and the preload of the torsion spring 804 ensures that the scraper 806 connected to it is always adaptively pressed against the inner wall of the drum 1. For better cleaning of the drum, the drum 1 can be tilted at a certain angle, allowing the scraped material to flow out from the discharge ramp 4 with the water flow, thus efficiently removing residual material. The scraper 806 is detachably connected via a coupling 805 and a fixing piece 807; this modular design greatly facilitates the replacement of easily worn parts. To further improve the reliability of the equipment, this invention also includes an auxiliary limiting system, where an auxiliary wheel 6 mounted on the bracket 7 of the base plate 2 engages with the groove of the upper limit wheel 101 of the drum. This convex-concave mechanical structure effectively counteracts the axial force generated during the operation of the drum 1, preventing the drum 1 from shifting and ensuring smooth operation.

[0024] In this embodiment, a plurality of brackets 7 are also installed on the base plate 2, and each bracket 7 is equipped with an auxiliary wheel 6. The limiting wheel 101 has a groove, and the auxiliary wheel 6 cooperates with the groove.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
