Abstract
Description
Technical Field
[0001] This utility model relates to the field of compound fertilizer vibrating screen technology, specifically a high-tower compound fertilizer vibrating screen device. Background Technology
[0002] High-tower compound fertilizer is one of the new technologies in my country's compound fertilizer production process. It is a melt granulation method for urea and potassium fertilizer. It utilizes the principle of rapid crystallization after urea melts. Ammonium phosphate is heated and metered, along with urea and potassium slurry, and then sprayed into a high tower through nozzles to produce compound fertilizer granules. This fertilizer is characterized by uniform and smooth granules, melt pores, and non-caking. However, the production process of high-tower compound fertilizer requires screening and grading of the compound fertilizer granules.
[0003] For example, Chinese patent application CN202420530936.4 discloses a high-tower compound fertilizer vibrating screen device, comprising a tank body. A tank cover is detachably mounted on the upper end of the tank body. A feed hopper is fixedly fitted inside the tank cover. A motor is fixedly mounted in the middle of the upper end of the tank cover. The output end of the motor passes through the tank cover and is rotatably connected to it. A square rod is welded to the lower end of the output end. A square block is slidably connected to the outer side of the square rod. A support cylinder is fixedly fitted inside the tank body. This invention uses a motor to drive the square rod to rotate, which in turn causes the square block to drive the screen to rotate through the cooperation of a turntable and a hanging rod. Furthermore, through the cooperation of spring plates and stop blocks, the screen vibrates up and down, resulting in centrifugal screening. This prevents the screen from clogging, improves screening efficiency, and causes clumps to roll relative to each other on the screen, breaking them up and separating them during screening.
[0004] However, in actual use, when multi-stage screening of high-tower compound fertilizer is required, the above device can only screen the high-tower compound fertilizer once through the screen. At the same time, the screen in the device cannot be replaced, which limits the screening process and reduces the screening effect. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a high-tower compound fertilizer vibrating sieving device. By disassembling and assembling three fixed frames, the first, second, and third sieves perform multi-stage vibrating sieving of the high-tower compound fertilizer, effectively removing impurities and lumps, ensuring particle uniformity, improving the physical quality of the fertilizer, and reducing segregation during application. Simultaneously, the screened fine powder can be reused for granulation, reducing raw material waste and improving production efficiency, effectively solving the problems in the background technology.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-tower compound fertilizer vibrating screen device, including a fixed base:
[0007] The top of the fixed base is equipped with a screening component for multi-stage vibrating screening of high-tower compound fertilizer;
[0008] The fixed base is equipped with a vibration component for driving the screening component to vibrate;
[0009] The screening assembly includes three fixed frames arranged vertically, with a threaded inner cylinder fixed between each of the three fixed frames. Adjacent threaded inner cylinders are connected by a threaded frame. A first screen frame, a second screen frame, and a third screen frame are fixed inside the three fixed frames respectively, and the three fixed frames are interconnected, which facilitates multi-stage vibrating screening of high-tower compound fertilizer.
[0010] Preferably, each of the three fixed frames has a discharge port on its front side, and a discharge frame is fixedly installed on the front side of each discharge port. The bottom and top of each discharge frame have locking interfaces, and a lifting plate is locked in the locking interface. A feeding frame is fixedly installed on the top of the fixed frame, so that the high-tower compound fertilizer can be put into the fixed frame through the feeding frame.
[0011] Preferably, the vibration assembly includes two L-shaped fixing rods, which are respectively fixed at both ends of the bottom of the bottom fixing frame, and are respectively located at both ends inside the fixing seat, so as to facilitate the lifting and lowering of the L-shaped fixing rods to drive the fixing frame to lift and lower.
[0012] Preferably, a telescopic rod is fixedly provided at both the front and rear ends of the bottom of the L-shaped fixing rod and the bottom end of the interior of the fixing seat. A spring is sleeved on the telescopic rod, and the top and bottom ends of the spring are fixedly connected to the bottom of the L-shaped fixing rod and the bottom end of the interior of the fixing seat, respectively. This facilitates the compression of the telescopic rod and the spring during the lifting and lowering of the L-shaped fixing rod, thereby limiting the movement of the L-shaped fixing rod.
[0013] Preferably, the two inner side walls of the fixed base are connected by the same rotating shaft through a bearing. A motor is fixedly installed on one outer wall of the fixed base. The output shaft of the motor passes through one side of the fixed base and is fixedly connected to one end of the rotating shaft. Two eccentric wheels are fixedly installed on the rotating shaft, and the two eccentric wheels are respectively located at the bottom of two L-shaped fixed rods, so as to facilitate the rotation of the eccentric wheels to impact the L-shaped fixed rods for lifting and lowering.
[0014] Preferably, a control panel for controlling the motor is fixedly provided on one side of the fixed base, and the control panel is located on the front side of the motor. A storage frame is movably provided at the bottom of the fixed base to facilitate the collection of the final screened high-tower compound fertilizer.
[0015] Compared with the prior art, this utility model provides a high-tower compound fertilizer vibrating screen device, which has the following beneficial effects:
[0016] 1. This utility model uses the requirement of disassembly and splicing of three fixed frames, and then uses the first screen frame, the second screen frame and the third screen frame to perform multi-stage vibrating screening of high tower compound fertilizer, thereby effectively removing impurities and lumps in high tower compound fertilizer, ensuring particle uniformity, improving the physical quality of fertilizer, and reducing segregation during application; at the same time, the fine powder screened out can be reused for granulation, reducing raw material waste and improving production efficiency.
[0017] 2. By setting up a vibration component, when it is necessary to vibrate and screen the high-tower compound fertilizer, the motor can be controlled through the control panel. The motor drives the rotating shaft to rotate, which in turn drives the two eccentric wheels to rotate. The two eccentric wheels then strike the L-shaped fixed rod to raise and lower. During the raising and lowering process, the telescopic rod and spring are stretched, which limits the movement of the L-shaped fixed rod. The raising and lowering of the L-shaped fixed rod will drive the top fixed frame to rise and vibrate, thus facilitating the screening of the high-tower compound fertilizer added inside the fixed frame and ensuring the effectiveness of the high-tower compound fertilizer screening.

Detailed Implementation
[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] like Figure 1-5As shown, this utility model provides a high-tower compound fertilizer vibrating screen device, including a fixed base 1, and a storage frame 5 is movably provided at the bottom of the fixed base 1 to facilitate the collection of the high-tower compound fertilizer that has been screened out.
[0027] like Figure 1-5 As shown, the top of the fixed base 1 is provided with a screening component 2 for multi-stage vibrating screening of high-tower compound fertilizer. The screening component 2 includes three fixed frames 21 distributed vertically. Each of the three fixed frames 21 is fixed with a threaded inner cylinder 22. Adjacent threaded inner cylinders 22 are connected by a threaded frame 23. The three fixed frames 21 are respectively fixed with a first screen frame 24, a second screen frame 25, and a third screen frame 26. The three fixed frames 21 are interconnected to facilitate multi-stage vibrating screening of high-tower compound fertilizer. Each of the three fixed frames 21 has a discharge port on its front side. Each discharge port has a discharge frame 27 fixed on its front side. The bottom and top of the discharge frame 27 have a locking interface 28. A lifting plate 29 is locked in the locking interface 28. The top of the top fixed frame 21 is fixed with a feeding frame 3 to facilitate feeding high-tower compound fertilizer into the fixed frame 21 through the feeding frame 3.
[0028] By setting the screening component 2, the middle fixed frame 21 can be rotated according to actual screening requirements, so that the threaded inner cylinders 22 at the top and bottom of the fixed frame 21 can be disassembled by threads. Then, the top fixed frame 21 and the bottom fixed frame 21 can be threadedly spliced together by the threaded inner cylinders 22 and the threaded frame 23. Figure 4 As shown, by pouring the high-tower compound fertilizer to be screened from the feeding frame 3 into the top fixed frame 21, it undergoes primary screening through the first screen frame 24. The high-tower compound fertilizer remaining on the top of the first screen frame 24 can be discharged from the discharge frame 27 by pulling up the lifting plate 29. The screened high-tower compound fertilizer re-enters the bottom fixed frame 21 and undergoes secondary screening through the third screen frame 26. The high-tower compound fertilizer remaining on the top of the third screen frame 26 can be discharged through the discharge frame 27. The screened high-tower compound fertilizer falls into the collection frame 5 for collection. This splicing method can achieve three-level screening.
[0029] If the middle fixing frame 21 is not removed, such as Figure 1 , 2 As shown, by pouring the high-tower compound fertilizer to be screened from the feeding frame 3 into the top fixed frame 21, it undergoes primary screening through the first screen frame 24. The high-tower compound fertilizer remaining on the top of the first screen frame 24 can be discharged from the discharge frame 27 by pulling up the lifting plate 29. The screened high-tower compound fertilizer re-enters the middle fixed frame 21 and is then screened through the second screen frame 25. The high-tower compound fertilizer remaining on the top of the second screen frame 25 is discharged through the discharge frame 27. The screened high-tower compound fertilizer re-enters the bottom fixed frame 21 and is screened in the same way. This splicing method can achieve four-level screening.
[0030] This effectively removes impurities and lumps from high-tower compound fertilizers, ensuring granule uniformity, improving fertilizer physical quality, and reducing segregation during application. Meanwhile, the screened fine powder can be reused for granulation, reducing raw material waste and improving production efficiency.
[0031] like Figure 1-5 As shown, the fixed base 1 is equipped with a vibration component 4 for driving the screening component 2 to vibrate. The vibration component 4 includes two L-shaped fixed rods 41, which are respectively fixed at both ends of the bottom of the bottom fixed frame 21. The two L-shaped fixed rods 41 are also located at both ends inside the fixed base 1, which facilitates the lifting and lowering of the L-shaped fixed rods 41 to drive the fixed frame 21 to lift and lower. Telescopic rods 42 are fixed between the front and rear ends of the bottom of the L-shaped fixed rods 41 and the bottom end inside the fixed base 1.
[0032] A spring 43 is fitted onto the telescopic rod 42. The top and bottom ends of the spring 43 are fixedly connected to the bottom of the L-shaped fixed rod 41 and the bottom of the interior of the fixed seat 1, respectively. This facilitates the compression of the telescopic rod 42 and the spring 43 during the lifting and lowering of the L-shaped fixed rod 41, thereby limiting the movement of the L-shaped fixed rod 41. The two inner side walls of the fixed seat 1 are connected by a common rotating shaft 44 through a bearing. A motor 46 is fixedly mounted on one outer wall of the fixed seat 1. The output shaft of the motor 46 passes through one side of the fixed seat 1 and is fixedly connected to one end of the rotating shaft 44. Two eccentric wheels 45 are fixedly mounted on the rotating shaft 44, and the two eccentric wheels 45 are respectively located at the bottom of the two L-shaped fixed rods 41, so that the eccentric wheels 45 can rotate and impact the L-shaped fixed rods 41 to lift and lower. A control panel 6 for controlling the operation of the motor 46 is fixedly mounted on one side of the fixed seat 1, and the control panel 6 is located in front of the motor 46.
[0033] By setting up the vibration component 4, when it is necessary to vibrate and screen the high-tower compound fertilizer, the motor 46 can be controlled to work through the control panel 6. The motor 46 drives the rotating shaft 44 to rotate, which in turn drives the two eccentric wheels 45 to rotate. The two eccentric wheels 45 rotate and strike the L-shaped fixed rod 41 to lift and lower. During the lifting and lowering process, the L-shaped fixed rod 41 is stretched by the telescopic rod 42 and the spring 43, which limits the lifting and lowering of the L-shaped fixed rod 41. The lifting and lowering of the L-shaped fixed rod 41 will drive the top fixed frame 21 to achieve lifting and lowering vibration, which facilitates the vibration and screening of the high-tower compound fertilizer added inside the fixed frame 21 and ensures the effect of the high-tower compound fertilizer vibration and screening.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
