Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, specifically to a fertilizer drying and screening device. Background Technology

[0002] Fertilizer drying and screening equipment is a key component in fertilizer production. It is used to remove excess moisture from granular fertilizers and accurately classify particle size. Typically, fertilizer drying and screening equipment consists of a drying system and a screening system. It is used in compound fertilizer production lines, organic fertilizer production lines, water-soluble fertilizer production lines, and other similar applications.

[0003] For example, Chinese patent CN206763329U, entitled "A Screening Cylinder Structure for Fertilizer Screening Equipment," includes a first positioning plate, a second positioning plate, and a first and second cylindrical screen. The first screen is positioned inside the second screen. One end of the first screen has a first positioning ring, and the other end has a second positioning ring. One end of the second screen has a third positioning ring, and the other end has a fourth positioning ring. The first positioning plate has a first annular groove that mates with the first positioning ring, and also a second annular groove that mates with the third positioning ring. Both the second and fourth positioning rings have annular protrusions. The second positioning plate has a groove that mates with the annular protrusions. The second positioning plate has a sealing ring and a sealing gasket on its inner side, and a screw is welded to the first positioning plate. The screw extends through to one side of the second positioning plate and is threaded with a nut. The first positioning plate has a mounting part on one side, which has a shaft hole that mates with the rotating shaft on the fertilizer screening equipment. Two first mounting plates are provided on the first positioning plates on both sides of the first positioning ring. Each of the two first mounting plates has a first locking plate for fixing the first positioning ring. The first mounting plates have first mounting screws for fixing the first mounting plate and the first positioning plate. Two second mounting plates are provided on the first positioning plates on both sides of the third positioning ring.

[0004] While the existing technologies can achieve fertilizer screening, in practical use, the screening effect is not good enough. Fertilizer is usually screened through a stationary filter plate, which causes the fertilizer to be squeezed between each other, resulting in some fertilizer being stuck at the top of the filter plate, thus affecting the screening quality. On the other hand, it is difficult to adjust the tilt angle of the box, which is usually set vertically, resulting in too short a contact time between the fertilizer and the filter mechanism, thus reducing the screening efficiency. Therefore, it does not meet the current needs. In response, we propose a fertilizer drying and screening device. Utility Model Content

[0005] The purpose of this invention is to provide a fertilizer drying and screening device to solve the problems mentioned in the background art, such as the poor screening effect of fertilizer and the difficulty in adjusting the tilt angle of the box.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fertilizer drying and screening device, comprising a box body, a screening chamber located at the center of the box body, the lower end of the screening chamber being an inclined structure, a rotating rod fixedly installed above the screening chamber, both sides of the rotating rod being rotatably connected to the inner wall of the screening chamber, a filter cylinder fixedly installed outside the rotating rod, the filter cylinder having open structures on both sides, a plurality of baffles fixedly installed inside the filter cylinder, the baffles being distributed in a ring at equal intervals, and a plurality of heating wires being installed inside the side wall of the box body, the heating wires being distributed at equal intervals.

[0007] Preferably, a first motor is fixedly installed on the upper part of both sides of the outer side of the box, and the output shaft of the first motor extends into the interior of the screening chamber and is fixedly connected to the rotating rod.

[0008] Preferably, a second connecting seat is fixedly provided on both sides of the lower end of the box body. An installation rod is fixedly provided inside the second connecting seat. The front and rear ends of the installation rod extend to the outside of the second connecting seat. An installation seat is fixedly provided at the front and rear ends of the installation rod. A hydraulic telescopic device is fixedly provided at the lower end of the installation seat located on one side of the box body. A first connecting seat is fixedly provided at the lower end of the fixed end of the hydraulic telescopic device. A base is provided outside the first connecting seat. The base is rotatably connected to the first connecting seat.

[0009] Preferably, a support rod is fixedly installed at the lower end of the mounting base on the other side of the housing, and the housing is kept horizontal by the support rod and the hydraulic telescopic device.

[0010] Preferably, a through hole is provided on the lower side of one side of the box, and the through hole communicates with the screening chamber.

[0011] Preferably, the front and rear ends of the housing above the through hole opening are fixedly provided with fixed seats, the fixed seats are symmetrically arranged, and a fixed rod is provided between the fixed seats. The front and rear ends of the fixed rod are rotatably connected to the fixed seats. A rotating plate is fixedly provided on the outside of the fixed rod, and the rotating plate corresponds to the position of the through hole.

[0012] Preferably, a second motor is fixedly installed on one side of the outer side of the fixed base, and the output shaft of the second motor extends to the other side of the fixed base and is fixedly connected to the fixed rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can screen and dry fertilizer by using a heating wire and a filter cylinder. When screening fertilizer, the fertilizer has been loaded into the filter cylinder. At this time, the heating wire is energized. The heating wire itself has a certain resistance. When the current passes through the heating wire, the heating wire will generate heat. The heat generated by the heating wire is transferred to the screening chamber through the side wall of the box, which raises the temperature inside the screening chamber and accelerates the evaporation of water in the fertilizer. Then, the first motor is turned on. The output shaft of the first motor drives the rotating rod to rotate, which causes the filter cylinder fixedly connected to the rotating rod to rotate. The rotating filter cylinder and baffle cause the fertilizer to tumble in the filter cylinder. At this time, fertilizer of suitable fineness falls through the mesh of the filter cylinder to the lower end of the screening chamber, thereby improving the screening effect of the fertilizer.

[0015] (2) This utility model can adjust the tilt angle of the box body through the hydraulic telescopic device and the through hole. When fertilizer is being screened, the fertilizer has been loaded into the filter cylinder and the filter cylinder is in working condition. At this time, the operator opens the hydraulic telescopic device, so that the telescopic end of the hydraulic telescopic device extends and lifts one side of the box body through the telescopic end of the hydraulic telescopic device. During this process, the mounting base rotates outside the mounting rod and the first connecting seat rotates on the base until the box body is adjusted to a suitable tilt angle. At this time, the fertilizer moves in the filter cylinder and cooperates with the rotation of the filter cylinder to increase the contact time between the fertilizer and the filter cylinder, thereby improving the screening effect of the fertilizer. At the same time, the tilted box body can make the screened fertilizer move closer to the through hole, which speeds up the discharge speed.

[0016] (3) This utility model can adjust the opening angle of the through hole through the second motor and the rotating plate. When the fertilizer is screened, the fertilizer has been screened. Then the box is adjusted to a suitable tilt angle. At this time, the operator turns on the second motor, so that the output shaft of the second motor drives the fixed rod to rotate slowly and uniformly counterclockwise. At the same time, the rotating plate fixedly connected to the fixed rod rotates together until the rotating plate is rotated to a suitable angle. At this time, the fertilizer is discharged from the screening chamber through the gap between the through hole and the rotating plate, avoiding the situation where the fertilizer is not collected in time due to the discharge speed being too fast.

The output shaft of the first motor 4 extends into the interior of the screening chamber 2 and is fixedly connected to the rotating rod 5, so as to facilitate the screening and drying of fertilizer through the filter cylinder 3 and the heating wires 17.

[0025] Please see Figure 1 , Figure 2 and Figure 3 A second connecting seat 18 is fixedly installed on both sides of the lower end of the box body 1. An installation rod 19 is fixedly installed inside the second connecting seat 18. The front and rear ends of the installation rod 19 extend to the outside of the second connecting seat 18. An installation seat 9 is fixedly installed at the front and rear ends of the installation rod 19. A hydraulic telescopic device 10 is fixedly installed at the lower end of the installation seat 9 on one side of the box body 1. A first connecting seat 11 is fixedly installed at the lower end of the fixed end of the hydraulic telescopic device 10. A base 12 is installed on the outside of the first connecting seat 11. The base 12 is rotatably connected to the first connecting seat 11. A support rod 13 is fixedly installed at the lower end of the installation seat 9 on the other side of the box body 1. The box body 1 is kept horizontal on the support rod 13 and the hydraulic telescopic device 10, which facilitates the adjustment of the tilt angle of the box body 1 by the hydraulic telescopic device 10.

[0026] Please see Figure 1 and Figure 2 A through hole 15 is provided on the lower side of one side of the box body 1. The through hole 15 communicates with the screening chamber 2. The front and rear ends of the box body 1 above the opening of the through hole 15 are fixedly provided with fixed seats 7. The fixed seats 7 are symmetrically arranged. A fixed rod 14 is provided between the fixed seats 7. The front and rear ends of the fixed rod 14 are rotatably connected to the fixed seat 7. A rotating plate 8 is fixedly provided on the outside of the fixed rod 14. The rotating plate 8 corresponds to the position of the through hole 15.

The output shaft of the second motor 16 extends to the other side of the fixed seat 7 and is fixedly connected to the fixed rod 14, so as to facilitate the rotation of the rotating plate 8 by the second motor 16.

[0027] Working principle: During use, fertilizer is loaded into the filter cylinder 3. First, the heating wire 17 is energized. The heating wire 17 has a certain resistance, generating heat when current passes through it. This heat is transferred through the side wall of the housing 1 to the screening chamber 2, raising the temperature inside and accelerating the evaporation of moisture from the fertilizer. Then, the first motor 4 is turned on, and its output shaft drives the rotating rod 5 to rotate, causing the filter cylinder 3, which is fixedly connected to the rotating rod 5, to rotate. The rotating filter cylinder 3 and the baffle 6 cause the fertilizer to tumble within it. Fertilizer of suitable fineness falls through the mesh of the filter cylinder 3 to the lower end of the screening chamber 2. Simultaneously, the operator activates the hydraulic telescopic device 10, causing its telescopic end to extend... The hydraulic telescopic device 10 extends the height of one side of the box 1. During this process, the mounting base 9 rotates outside the mounting rod 19, and the first connecting seat 11 rotates on the base 12 until the box 1 is adjusted to a suitable tilt angle. At this time, the fertilizer moves in the filter cylinder 3 and, in conjunction with the rotation of the filter cylinder 3, increases the contact time between the fertilizer and the filter cylinder 3. At the same time, the tilted box 1 allows the screened fertilizer to move closer to the through hole 15. At this time, the operator turns on the second motor 16, so that the output shaft of the second motor 16 drives the fixed rod 14 to rotate slowly and uniformly counterclockwise. At the same time, the rotating plate 8, which is fixedly connected to the fixed rod 14, rotates together until the rotating plate 8 is rotated to a suitable angle. At this time, the fertilizer is discharged from the screening chamber 2 through the gap between the through hole 15 and the rotating plate 8.
