Description

Technical Field

[0001] This invention relates to the field of feed separation device technology, and in particular to a feed separation device for a granulator used in the production of bio-fertilizer. Background Technology

[0002] In the production of bio-fertilizers, the raw materials need to be effectively transported and screened before the granulation process to remove large particles or clumps that do not meet the granulation requirements, thus ensuring granulation quality and efficiency.

[0003] Currently, most of the feeding and separating devices in existing granulators have a fixed and simple structure. On the one hand, the relative positions of the conveying mechanism and the screening mechanism are fixed, and the overall structure cannot be flexibly adjusted according to the raw material conveying volume and screening requirements. This leads to easy accumulation and blockage during the raw material conveying process, affecting the continuity of feeding.

[0004] On the other hand, most screening components are fixed screen structures, which can only achieve single-level screening. Furthermore, during the screening process, raw materials are prone to adhere to and clog the screen surface, reducing screening efficiency and separation effect.

[0005] Meanwhile, the existing equipment's frame structure lacks adjustability and cannot be flexibly adapted to the spatial layout, raw material conveying height, and other requirements of the actual production scenario, thus limiting its applicability.

[0006] In addition, the connection between the conveying components and the screening components of some devices is unreasonable, which makes it easy for raw materials to spill when they enter the screening mechanism from the conveying mechanism, resulting in waste of raw materials and further affecting the continuity and economy of production. Summary of the Invention

Limiting sliders are fixedly installed at the lower corner positions of the opposite sides of the two second U-shaped frames on the left and right sides. The limiting sliders are slidably mounted on the outer circumferential surface of the adjacent slide rods.

[0012] Preferably, a U-shaped hinge is fixedly installed on the outer upper end of each of the two second U-shaped frames, a connecting hinge is rotatably installed on the inner side of each U-shaped hinge, a third U-shaped frame is fixedly installed on the inner upper end of the connecting hinge, a fourth U-shaped frame is rotatably installed on the upper end of the third U-shaped frame, and a limit rod is rotatably installed on one adjacent inner end of each of the second, third, and fourth U-shaped frames.

[0013] Preferably, the upper ends of the two fourth U-shaped frames that are far apart are connected to the interior. A ring is fixedly installed at the upper ends of the two fourth U-shaped frames that are far apart. A T-shaped groove is opened from the outer side of the ring to the interior. A third through-hole is opened from the outer circumferential surface of the ring to the interior.

[0014] Preferably, a second motor is fixedly installed inside the two fourth U-shaped frames on the left and right sides, a drive gear is fixedly installed on the output shaft of the second motor, a gear ring is rotatably installed inside the T-shaped groove, the drive gear passes through the third through-hole and meshes with the gear ring, and a screening cylinder is fixedly installed at the ends of the two gear rings on the left and right sides that are far apart.

[0015] Preferably, an intermediate plate is fixedly installed in the middle of the screening cylinder, and circular material holes are opened in an annular array from one end to the other end of the intermediate plate. Arc-shaped material pipes are evenly fixedly installed in an annular array on the outer circumferential surface of the screening cylinder. A servo motor is fixedly installed in the center of the outer side of the screening cylinder. A disturbance plate is evenly fixedly installed in an annular array on the circumferential surface of the output shaft of the servo motor. The disturbance plate is located inside the screening cylinder.

[0016] Preferably, a forward and reverse motor is fixedly installed at the center of the two base rods, and a second threaded rod is fixedly installed on the output shaft of each of the forward and reverse motors. A connecting slide is rotatably installed on the circumference of the second threaded rod, and connecting rods are rotatably installed at both ends of the connecting slide.

[0017] Preferably, a third motor is fixedly installed at the upper end of the connecting rod, and a rotating shaft is provided on the output shaft of the third motor and inside the fourth U-shaped frame. An installation conveyor belt is rotatably installed on the circumferential surface of the upper and lower rotating shafts.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through a second U-shaped frame that moves up and down, a connecting slide, a connecting rod, and a third motor, can change the different operating states of the inner conveyor belt. This allows the device to flexibly adapt to different height differences and angle requirements during the raw material conveying process. It can achieve horizontal conveying mode and can also switch to inclined conveying mode to accurately match the feeding position of the subsequent granulation process. It can also dynamically adjust the running speed and tension of the conveyor belt according to the real-time flow of the raw material, ensuring the uniformity and continuity of raw material conveying. This solves the problem of the fixed operating state of traditional conveyor belts and their inability to flexibly respond to the dynamic connection needs between the feeding separation device and the granulator. It effectively enhances the collaborative operation capability of each link of the device and further optimizes the overall efficiency and adaptability of the production process.

[0019] 2. This invention uses a first motor to drive a first threaded rod, which in turn moves the slide table. Combined with the guiding action of the slide rod and the limiting slider, this allows for vertical height adjustment of the second U-shaped frame. Simultaneously, the rotation of the U-shaped hinge and connecting hinge allows for flexible angle adjustment of the third and fourth U-shaped frames. This enables the entire device to flexibly adjust the height and angle of the frame structure according to the spatial layout of the production scenario, the material conveying height, and the required feed rate. This significantly improves the adaptability and applicability of the device, solving the problem of traditional fixed-structure devices being unable to flexibly adapt to different production needs.

[0020] 3. This invention uses a second motor to drive a gear ring, which rotates the screening cylinder. Combined with the internal intermediate plate, servo motor, and disturbance plate of the screening cylinder, it achieves dynamic and efficient screening of raw materials. The servo motor drives the disturbance plate to agitate the raw materials inside the screening cylinder, preventing them from adhering and clogging the discharge hole and the circular material hole of the intermediate plate. Simultaneously, the rotating screening cylinder, in conjunction with the arc-shaped material pipe, further improves screening uniformity and separation effect, solving the problems of low screening efficiency and easy clogging of traditional fixed screens. This significantly improves the thoroughness of raw material separation and screening efficiency, ensuring continuous production.

[0021] 4. This invention, through a multi-level frame structure consisting of a base rod, a first U-shaped frame, a second U-shaped frame, a third U-shaped frame, and a fourth U-shaped frame, coupled with a conveyor belt installed on the inner side and a feeding frame fixed at equal intervals on the outer side, and a screening cylinder with a discharge hole rotatably installed on the outer side of the upper end of the fourth U-shaped frame, effectively solves the problems of fixed structure and unreasonable connection between conveying and screening in existing devices. The multi-level frame provides a stable installation foundation for conveying and screening. The feeding frame enables quantitative and orderly conveying of raw materials, avoiding accumulation and blockage during conveying, and ensuring continuous feeding. The reasonable layout of the conveyor belt and screening cylinder allows the raw materials to enter the screening cylinder directly from the conveying mechanism, reducing material spillage and waste. The screening cylinder, through rotation and the discharge hole, achieves efficient separation of raw materials, effectively removing impurities that do not meet the requirements, ensuring the purity of the feed, providing high-quality raw materials for subsequent granulation processes, and significantly improving granulation quality and production efficiency.

Detailed Implementation

[0025] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 10 The present invention provides a technical solution: A feed separation device for a granulator used in the production of bio-fertilizer includes two base rods 1. Symmetrical first U-shaped frames 2 are fixedly mounted on the upper surfaces of the two base rods 1. First through-holes 201 are opened into the front and rear sides of the two first U-shaped frames 2. Second through-holes 202 are opened into the sides of the two first U-shaped frames 2 that are furthest apart. A baffle plate 204 is rotatably mounted inside the second through-holes 202. A feed pipe 203 is fixedly mounted at the furthest end of the two first U-shaped frames 2, outside the second through-holes 202. Figure 3 As shown.

[0027] During use, the raw material on the outside first passes through the feed pipe 203, and then through the second through-hole 202. (It should be noted that after passing through the second through-hole 202, the raw material will enter the interior of the subsequent feeding frame 507. When the subsequent feeding frame 507 moves, it will push the baffle plate 204 to rotate. When the baffle plate 204 is at a 90-degree angle, it can partially block the second through-hole 202, thus blocking the raw material and keeping it inside the second through-hole 202. After the feeding frame 507, which is in contact with the baffle plate 204, moves away, the baffle plate 204 will automatically reset. After resetting, the raw material inside the second through-hole 202 will continue to slide down, thus entering the subsequent feeding frame 507.) (Regarding the interior of the corresponding feeding frame 507), it should be noted that the inner opening of the second through-hole 202 is in a contracted state, that is, the second through-hole 202 has a trapezoidal structure in its planar state. Therefore, it can prevent the material from sliding into the interior of the feeding frame 507 when the lower feeding frame 507 is not attached to the barrier plate 204 after the previous feeding frame 507 separates from the barrier plate 204, thus preventing the material from falling. Moreover, the upper end of the outer opening of the feeding frame 507 is in a contracted state, that is, the lower end of the opening of the feeding frame 507 is attached to the inner side of the first U-shaped frame 2, and the upper end of the opening is shorter than the lower end, thus allowing the material to slide into the interior of the feeding frame 507.

[0028] Mounting plates 205 are fixedly installed at the corners of the upper outer side of the first U-shaped frame 2. Slide rods 206 are fixedly installed on the upper surface of the mounting plates 205. A first motor 207 is fixedly installed at the center of the two opposite sides of the first U-shaped frames 2. A first threaded rod 208 is fixedly installed on the output shaft of the first motor 207. A slide table 209 is threadedly mounted on the circumferential surface of the first threaded rod 208. A second U-shaped frame 3 is fixedly installed at the adjacent end of the two slide tables 209. A limit slider 301 is fixedly installed at the lower outer corner of the second U-shaped frame 3. The limit sliders 301 are slidably mounted on the outer circumferential surface of the adjacent slide rods 206.

[0029] Therefore, during use, when the first motor 207 is started, the output shaft of the first motor 207 drives the first threaded rod 208 to rotate synchronously. When the first threaded rod 208 rotates, it drives the slide table 209 to move up and down. When the slide table 209 moves up and down, it drives the second U-shaped frame 3 to move up and down synchronously. As the second U-shaped frame 3 moves up and down, it can change the subsequent working height of the device, so that the device can cope with working equipment of different heights. During the sliding of the second U-shaped frame 3, the slide rod 206 and the limiting slider 301 can keep the second U-shaped frame 3 in a linear motion, so that the second U-shaped frame 3 does not rotate synchronously with the first threaded rod 208.

[0030] The upper outer side of the second U-shaped frame 3 is fixedly equipped with U-shaped hinges 302, and the inner side of each U-shaped hinge 302 is rotatably equipped with a connecting hinge 303. The upper inner side of the connecting hinge 303 is fixedly equipped with a third U-shaped frame 304, such as... Figure 4 As shown.

[0031] During use, the third U-shaped frame 304 can rotate through the operation of the U-shaped hinge 302 and the connecting hinge 303.

[0032] A fourth U-shaped frame 305 is rotatably mounted on the upper end of the third U-shaped frame 304. (It should be noted that there is a certain gap between the two fourth U-shaped frames 305, the gap of which is set according to the actual situation. The spacing needs to be designed through calculation to avoid obstruction when the two fourth U-shaped frames 305 are horizontally fitted laterally.) Furthermore, the second U-shaped frame 3 and the third U-shaped frame 304 are rotatably connected at adjacent positions on their outer sides, while the third U-shaped frame 304 and the fourth U-shaped frame 305 are rotatably connected on their inner sides. At the rotatable connection point of the third U-shaped frame 304 and the fourth U-shaped frame 305, an L-shaped through slot is formed inward for installing a hinge. Figure 5 As shown.

[0033] Therefore, during use, the third U-shaped frame 304 rotates along with the fourth U-shaped frame 305, so that the two third U-shaped frames 304 and the fourth U-shaped frame 305 can be in the same vertical position.

[0034] At this time, the left third U-shaped frame 304 and the fourth U-shaped frame 305 are brought to the same horizontal position by the structural U-shaped hinge 302 and the connecting hinge 303 on the left. At this time, the right fourth U-shaped frame 305 rotates 90 degrees to make it parallel to the horizontal fourth U-shaped frame 305. It should be noted that at this time, the right third U-shaped frame 304 does not rotate, so that the raw materials on the left and right sides are in the same screening cylinder 406.

[0035] Limiting rods 306 are rotatably installed on the front and rear sides of the interior of the second U-shaped frame 3, the third U-shaped frame 304, and the fourth U-shaped frame 305, such as... Figure 5 As shown, the two left and right limit rods 306 at the same horizontal height can perform auxiliary limit operation on the subsequent installation conveyor belt 506, so that when the upper end of the installation conveyor belt 506 is in a 90-degree state, there will be no friction between the inner sides of the second U-shaped frame 3, the third U-shaped frame 304 and the fourth U-shaped frame 305. Secondly, the two limit rods 306 at the front and rear will not hinder the movement of the feeding frame 507.

[0036] The upper outer side to the inner side of the fourth U-shaped frame 305 is a circular through-type structure, such as... Figure 4 As shown, a ring 4 is fixedly installed on the upper outer side of the fourth U-shaped frame 305. A T-shaped groove 401 is opened from the outer side to the inner side of the ring 4, and a third through-hole 402 is opened from the outer circumferential surface to the inner circumferential surface. A second motor 403 is fixedly installed on the upper outer side of the left and right fourth U-shaped frames 305. The output shaft of the second motor 403 extends to the outer side of the fourth U-shaped frame 305, and a drive gear 404 is fixedly installed on the output shaft. A gear ring 405 is rotatably installed inside the T-shaped groove 401. The gear ring 405 meshes with the drive gear 404 through the second through-hole 202. The two ends of the left and right gear rings 405 that are far apart extend to the outer side of the T-shaped groove 401, and a screening cylinder 406 is fixedly installed on the outer side.

[0037] During use, the second motor 403 is started, and the output shaft of the second motor 403 drives the drive gear 404 to rotate. The drive gear 404 drives the gear ring 405 to rotate. After the gear ring 405 rotates, it will drive the screening cylinder 406 to rotate synchronously, thereby changing the subsequent discharge holes 408 of different diameters to approach the fourth U-shaped frame 305.

[0038] The outer circumferential surface of the screening cylinder 406 is evenly arrayed with discharge holes 408, and an intermediate plate 407 is fixedly installed at the middle position of its inner side, dividing the interior of the screening cylinder 406 into two layers, such as... Figure 8 As shown.

[0039] The left and right sides of the intermediate plate 407 are evenly arranged with circular through-holes to allow the raw material to enter the lower layer of the screening cylinder 406 (when the screening cylinder 406 is in a horizontal state). Secondly, the outer circumferential surface of the fourth U-shaped frame 305 is evenly fixedly arranged with arc-shaped material pipes 409. It should be noted that a cloth bag is fixedly installed on the outside of the arc-shaped material pipes 409 to mitigate the collision of raw materials.

[0040] A servo motor 410 is fixedly installed on one end face of the screening cylinder 406 away from the fourth U-shaped frame 305. The output shaft of the servo motor 410 extends into the interior of the screening cylinder 406, and a disturbance plate 411 is fixedly installed in a ring array on the circumference of the output shaft. The middle plate 407 of the disturbance plate 411 and the inner right side of the screening cylinder 406 are in a close contact state. Figure 8 As shown.

[0041] Therefore, during use, the servo motor 410 is started, and the output shaft of the servo motor 410 rotates the disturbance plate 411. After the disturbance plate 411 rotates, it can disturb the raw material inside the screening cylinder 406, so that the raw material can pass through the corresponding discharge hole 408 and then enter the interior of the arc-shaped material pipe 409, and then enter the subsequent working device through the cloth bag.

[0042] A forward and reverse motor 5 is fixedly installed on the outer middle of the two base rods 1. A second threaded rod 501 is fixedly installed on the output shaft of the forward and reverse motor 5. A connecting slide 502 is rotatably installed on the circumferential surface of the second threaded rod 501. A connecting rod 503 is rotatably installed at both ends of the connecting slide 502. A third motor 504 is fixedly installed at the upper end of the connecting rod 503. A rotating shaft 505 is fixedly installed between the two corresponding third motors 504. A rotating shaft 505 is also rotatably installed on the upper inner side of the fourth U-shaped frame 305 (it should be noted that the third motor 504 passes through the first through-hole 201). A conveyor belt 506 is rotatably installed on the circumferential surface of the two rotating shafts 505. Feeding frames 507 are fixedly installed at equal intervals on the outer surface of the conveyor belt 506.

[0043] During use, the third motor 504 is started, and the output shaft of the third motor 504 drives the rotating shaft 505 to rotate. After the rotating shaft 505 rotates, it will drive the installation conveyor belt 506 to rotate synchronously. After the installation conveyor belt 506 rotates, it will drive the feeding frame 507 to rotate, so that the feeding frame 507 can rotate inside the first U-shaped frame 2, thereby allowing the raw material to enter the inside of the feeding frame 507, thus realizing the conveying of the raw material to the inside of the screening cylinder 406.

[0044] Working principle First, for the scenario requiring operation, the output shaft of the first motor 207 drives the first threaded rod 208 to rotate synchronously, thereby causing the slide table 209 to move up and down with the second U-shaped frame 3. The movement of the second U-shaped frame 3 causes the third U-shaped frame 304 to move synchronously, and the third U-shaped frame 304 will cause the fourth U-shaped frame 305 to move up and down synchronously.

[0045] However, it should be noted that whether to change the height needs to be adjusted based on the actual situation on site.

[0046] During the aforementioned adjustment process, the forward and reverse motor 5 needs to be started. The output shaft of the forward and reverse motor 5 drives the second threaded rod 501 to rotate synchronously. During the rotation of the second threaded rod 501, the connecting slide 502 will move synchronously. During the movement of the connecting slide 502, the connecting rod 503 will move synchronously. After the connecting rod 503 moves, it will drive the third motor 504 to move. After the third motor 504 moves, it will drive the rotating shaft 505 to move synchronously. This allows the installation conveyor belt 506 to move synchronously with the second U-shaped frame 3, preventing the rotating shaft 505 inside the fourth U-shaped frame 305 from failing to move the installation conveyor belt 506 synchronously.

[0047] Then, depending on the scenario and operation, the operation is carried out through the U-shaped hinge 302 and the connecting hinge 303, so that the third U-shaped frame 304 and the fourth U-shaped frame 305 rotate synchronously, so that the left and right third U-shaped frames 304 and fourth U-shaped frames 305 are in a horizontal state or different tilt states, so that the subsequent screening cylinder 406 can operate synchronously, so that the screening cylinder 406 can be located above the subsequent operating device, and the subsequent operating device can be connected to the arc-shaped material pipe 409 through the corresponding pipe or other connecting device.

[0048] Another possible scenario is that the third U-shaped frame 304 on the right side rotates 90 degrees along with the fourth U-shaped frame 305, while the third U-shaped frame 304 on the left side remains stationary and the fourth U-shaped frame 305 rotates, allowing the fourth U-shaped frame 305 on the left side to fit snugly against the fourth U-shaped frame 305 on the right side.

[0049] It should be noted that the fourth U-shaped frame 305 and the third U-shaped frame 304 on the left are rotatably connected at the lower end of the inner opening. It should also be noted that the hinges used at the rotatable connection position have a gap between them to avoid obstruction when the fourth U-shaped frame 305 and the third U-shaped frame 304 on the left are fitted together later.

[0050] When the above situation occurs, the installation conveyor belt 506 will not rub against the third U-shaped frame 304 and the fourth U-shaped frame 305 under the action of the limit rotating rod 306.

[0051] At this time, external raw materials can enter the interior of the feeding frame 507 through the feed pipe 203 and the second through-hole 202.

[0052] At this time, the third motor 504 is started. The output shaft of the third motor 504 drives the rotating shaft 505 to rotate. The rotating shaft 505 drives the installation conveyor belt 506 to rotate synchronously, which in turn drives the upper rotating shaft 505 to rotate synchronously.

[0053] At this time, the conveyor belt 506 moves the feeding frame 507, and the outer side of the feeding frame 507 fits against the inner side of the corresponding first U-shaped frame 2, preventing the raw material from rolling out.

[0054] At this time, as the feeding frame 507 moves, it can carry the raw material into the interior of the screening cylinder 406. It should be noted that the upper end of the installation conveyor belt 506 is located in the middle of the screening cylinder 406, so that the raw material can enter the interior of the screening cylinder 406.

[0055] It should be noted that at the connection between the screening cylinder 406 and the fourth U-shaped frame 305, a semi-circular baffle plate is provided in the lower half of the through hole from the outer to the inner side of the top of the fourth U-shaped frame 305. This is because, during vertical operation, the raw material may slide out on its own after entering. Therefore, to prevent the raw material from sliding out on its own, a baffle plate is fixedly installed in the lower half of the through hole of the fourth U-shaped frame 305. The height of the baffle plate is set according to the situation and should not affect the entry of the raw material.

[0056] When the servo motor 410 is started, the output shaft of the servo motor 410 rotates the disturbance plate 411. After the disturbance plate 411 rotates, it can move the raw material inside the screening cylinder 406. After the movement, the raw material inside will be screened out through the corresponding discharge hole 408, and then allowed to enter the corresponding device through the arc-shaped material pipe 409.

[0057] It should be noted that, since the screening cylinder 406 can be tilted, only one discharge hole 408 can operate at this time. Therefore, when the second motor 403 is started, the output shaft of the second motor 403 drives the drive gear 404 to rotate. The drive gear 404 drives the gear ring 405 to rotate synchronously. After the gear ring 405 rotates, the corresponding discharge hole 408 is positioned at the bottom, so that the corresponding raw material can be screened out through the discharge hole 408, thereby completing the conveying and separation operation.
