Description

Technical Field

[0001] This invention relates to the field of granulation machinery technology, specifically a flexible disc granulation device adapted to the efficient preparation of different particle sizes. Background Technology

[0002] Disc granulators are a common type of granulation equipment, widely used in chemical, agricultural, and construction industries. In recent years, with the implementation of national policies for the rational development and utilization of sand and gravel resources, the application of disc granulators in producing granular products to replace sand and gravel resources has gradually increased. Disc granulators need to be adapted to different raw materials during operation, and high granulation rates must be ensured by adjusting process parameters. Currently, most granulation equipment used to replace sand and gravel resources is a disc granulator, consisting of a granulation disc and a drive motor. However, it has significant drawbacks in use: when processing different raw materials, manual adjustment of process parameters and small-scale trial production are required, significantly increasing production costs; granulation efficiency is low, and the finished particles have uneven size, making it difficult to meet design standards for granulation quality.

[0003] Meanwhile, traditional granulators do not have a drying device before screening. The granules produced from the granulation disc have a high moisture content and strong surface stickiness. When they enter the screening stage, they are very easy to stick together and clump together, which not only clogs the screen and greatly reduces the screening accuracy and efficiency, but also requires frequent shutdowns to clean the sticky material, interrupting the continuous production process.

[0004] Therefore, a parameterized disc granulation device is designed to efficiently prepare materials of different particle sizes, ensuring that the materials entering the granulator can meet the particle size requirements; and to accurately control process parameters such as rotation speed, edge height, and tilt angle according to different materials, so as to improve granulation efficiency and reduce trial production costs for enterprises. Summary of the Invention

[0005] The purpose of this invention is to provide a parameterized disc granulation device that can efficiently prepare particles of different sizes, solving the following technical problems: Traditional disc granulation equipment generally suffers from poor parameter control flexibility, often relying on manual adjustment of parameters such as inclination angle and rotation speed. This not only results in low adjustment accuracy and is time-consuming and labor-intensive, but also makes it difficult to dynamically adapt to the granulation characteristics of different materials, easily leading to uneven particle size distribution, loose and brittle finished particles, and a significant reduction in granulation rate. Furthermore, traditional granulators lack a drying device before screening, resulting in particles with high moisture content and strong surface adhesion immediately after exiting the granulation disc. These particles easily adhere and clump together during screening, clogging the screen, significantly reducing screening accuracy and efficiency, and requiring frequent shutdowns to clean the adhered material, interrupting continuous production.

[0006] The present invention provides the following technical solution: a flexible disc granulation device for efficient preparation of different particle sizes, comprising a U-shaped support frame, a base provided at the upper end of the U-shaped support frame, an mounting frame rotatably provided at the upper end of the base, a granulation disc provided at the upper end of the mounting frame, and a first tilt angle adjustment component provided at the upper end of the base; The first tilt adjustment assembly includes a support base fixedly mounted on a base, a lead screw rotatably mounted on the support base, a first slider threadedly connected to the outer surface of the lead screw, a guide rail slidably mounted at the lower end of the first slider, and the two ends of the guide rail being respectively connected to the two ends of the support base, a support rod mounted at the upper end of the first slider, and the end of the support rod away from the first slider being connected to the bottom end of the mounting bracket.

[0007] As a further aspect of the present invention: a brushless motor is provided at the upper end of the mounting bracket, and the brushless motor is connected to a driver and a speed control disc for displaying real-time rotational speed.

[0008] As a further aspect of the present invention: an inclination sensor is provided on the upper surface of the mounting frame, the inclination sensor is used to detect the tilt angle of the granulation disk, and then the tilt angle of the granulation disk is controlled by the first inclination adjustment component.

[0009] As a further aspect of the present invention: an arc-shaped support frame is fixedly provided on the mounting frame, a crossbar is provided on one side of the arc-shaped support frame, a scraper is provided at the lower end of the crossbar, and the scraper is in contact with the inner bottom surface of the granulation disc.

[0010] As a further aspect of the present invention: a cover plate is provided at the upper end of the conveyor frame; Guide plates are symmetrically arranged at the upper end of the conveyor frame and on the side close to the granulation disc.

[0011] As a further aspect of the present invention: a conical discharge hopper is provided on one side of the screening box, and a push plate is provided on the other side of the screening box, the push plate being embedded in the side wall of the screening box; A flat cylinder is provided on the outer wall of the screening box, and one end of the flat cylinder passes through the side wall of the screening box and is connected to the push plate.

[0012] As a further aspect of the present invention: a first upright arc groove is symmetrically provided at the upper end of the rectangular frame, a circular groove is provided at the bottom end of the first upright arc groove, and a second upright arc groove perpendicular to the first upright arc groove is provided inside the rectangular frame and at the top end of the circular groove. The upper end of the screen is symmetrically rotatably provided with a sleeve, and a sleeve rod is slidably engaged inside the sleeve. The lower end of the sleeve rod extends to the outside of the sleeve and is fixedly provided with a vertical rod disc. A second return spring is sleeved on the outer surface of the sleeve rod and is provided between the sleeve and the vertical rod disc.

[0013] As a further aspect of the present invention: the upper end of the mounting frame is provided with a side height adjustment component, the side height adjustment component includes an electric push rod fixedly mounted on the mounting frame, the power output end of the electric push rod is connected to a retractable extended disc, and the retractable extended disc is slidably sleeved with the granulation disc.

[0014] As a further aspect of the present invention: an arc-shaped support frame is fixedly mounted on the mounting frame, and a displacement sensor is mounted on the arc-shaped support frame; The displacement sensor is used to control the elongation of the retractable extended disk.

[0015] As a further aspect of the present invention, the scraper is designed with an S-shaped structure.

[0016] The present invention has the following beneficial effects: (1) This invention uses a tilt sensor to provide real-time feedback data, and a stepper motor drives a lead screw and slider mechanism to achieve precise tilt adjustment and self-locking. A brushless motor is paired with a driver to achieve parameterized speed adaptation. A displacement sensor controls the extension and retraction of the extended disk to ensure stable side height. Multi-parameter coordinated adjustment effectively avoids the problem of insufficient precision in traditional manual adjustment, and greatly improves the uniformity of particle size of different particle sizes. At the same time, the tilt angle is detected to control the granulation process. Before the raw material is formed, the tilt angle can be controlled at a small position to increase the material contact rate and improve the forming efficiency. After the granules are formed, the tilt angle can be gradually increased so that the formed granules can be discharged smoothly. When the stepper motor stops, the position is self-locked by the braking device to maintain accurate angle.

[0017] (2) The present invention controls the elongation of the extended disc using a displacement sensor. Before pellet formation, the edge height of the disc can be appropriately increased to increase the movement time of the pellets within the disc and simultaneously increase the feeding amount. After pellet formation, the edge height can be gradually reduced to ensure that the formed pellets can be discharged smoothly. At the same time, when the edge height reaches the set height, the self-locking function of the electric push rod keeps the height unchanged. (3) The present invention uses an electric heating plate to dry and solidify the freshly formed high-moisture granules online. The heating temperature and the inclination angle of the conveyor frame can be dynamically adjusted according to the material viscosity and particle size. With the cover plate, hot air circulation is realized to accelerate the drying. This solves the problem of sieving adhesion and clumping caused by high moisture content and strong surface adhesion of granules in traditional granulators, avoids screen blockage and frequent shutdown for cleaning, and ensures continuous production process.

[0018] (4) This invention achieves high-frequency vibration screening by using a vibration motor in conjunction with a cam and a return spring, which can quickly separate qualified particles from powder impurities. The powder can be recycled and reused. The screen adopts a press-rotate quick-release structure. Through the interlocking of the upright disc and the arc groove, the screen can be disassembled and replaced without additional tools, adapting to the screening needs of different particle sizes and improving the flexible production capacity of the equipment.

[0019] (5) The present invention adopts an S-shaped flexible scraper design, which divides the three functional granulation areas—the retention area, the straight drop area, and the oblique flying area—by the material difference between the rigid scraper body and the flexible scraper. This orderly separates raw materials in different states, reduces mutual interference, enhances the mixing effect of materials, and accelerates the agglomeration and forming process of small particles, thereby achieving a dual improvement in granulation efficiency and particle compaction.

Detailed Implementation

[0023] 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.

[0024] Disc granulators, as commonly used granulation equipment, are widely used in chemical, agricultural, and construction fields. Driven by national policies promoting the rational development and utilization of sand and gravel resources, their application in producing granular products to replace sand and gravel resources is increasing. However, this equipment requires adaptation to different raw materials and adjustment of process parameters to ensure a high granulation rate. Existing similar equipment, however, consists only of a granulation disc and a drive motor, exhibiting significant shortcomings: adapting to different raw materials necessitates manual adjustment of process parameters and small-scale trial production, significantly increasing production costs. Furthermore, granulation efficiency is low, finished particles have uneven size, and the molding quality fails to meet design standards.

[0025] Therefore, the present invention aims to design a parameterized disc granulation device that can efficiently prepare different particle sizes, ensuring that the feed particle size meets the standard, and can accurately adjust process parameters such as rotation speed, edge height and tilt angle for different materials, thereby improving granulation efficiency and reducing enterprise trial production costs.

[0026] Example 1: A parameterized disc granulation device for efficient preparation of different particle sizes. Please refer to [link to example]. Figure 1 - Figure 3 As shown, it includes: U-shaped support frame 12, with a base 1 at the upper end of the U-shaped support frame 12, and mounting seats 3 symmetrically arranged at the upper end of the base 1. A first rotating rod 4 is arranged between the two symmetrical mounting seats 3. A mounting frame 5 is rotatably arranged on the outer surface of the first rotating rod 4 through two symmetrical guide sleeves. The mounting frame 5 can rotate relative to the first rotating rod 4. In order to adapt to the granulation characteristics of different materials, and at the same time control the residence time, rolling trajectory and compaction degree of the particles in the granulation chamber, so as to achieve efficient preparation of particles of different particle sizes, the mounting frame 5 can be flexibly adjusted by the corresponding first tilt angle adjustment component 2. An arc-shaped support frame 15 is fixedly arranged on the mounting frame 5. The granulation device includes a granulation disc 9 rotatably mounted on a mounting frame 5. The granulation disc 9 is driven by a brushless motor 7 mounted on the mounting frame 5. The brushless motor 7 has the advantages of low operating noise, precise speed adjustment and strong operating stability. It can flexibly adjust the rotation speed of the granulation disc 9 according to the preparation requirements of different particle sizes, so as to ensure the uniformity and molding efficiency of finished products of different particle sizes.

[0027] The first tilt adjustment assembly 2 includes a support base 201 fixedly mounted on a base 1. A lead screw 202 is rotatably mounted on the support base 201. A first slider 203 is threadedly connected to the outer surface of the lead screw 202. A guide rail 204 is slidably mounted on the lower end of the first slider 203, and both ends of the guide rail 204 are respectively connected to the two side walls of the support base 201. The guide rail 204 can strictly limit and guide the linear motion trajectory of the first slider 203, preventing the first slider 203 from circumferentially offset as the lead screw 202 rotates, and ensuring that the first slider 203 slides stably along the axial direction of the lead screw 202. One end of the lead screw 202... A stepper motor 205 is connected to the first slider 203, and a support rod 206 is rotatably connected to the upper end of the first slider 203. The end of the support rod 206 away from the first slider 203 is connected to the bottom end of the mounting frame 5. An inclination sensor 207 is provided on the upper surface of the mounting frame 5. The inclination sensor 207 can collect the tilt angle data of the mounting frame 5 in real time and feed the data back to the control system for comparison with the preset tilt angle target value. When there is a deviation between the detected angle and the target value, the control system will drive the stepper motor 205 to rotate forward or reverse, thereby moving the first slider 203 to adjust the tilt angle of the mounting frame 5 until the angle reaches the preset value. This invention adds a parameterized tilt angle adjustment component 2 to a conventional granulator. A stepper motor 205 drives a first slider 203 to move via a lead screw 202. During the sliding process of the first slider 203, the support rod 206 connected to its upper end will change position accordingly. Through the pushing or pulling action of the support rod 206, the mounting frame 5 is driven to deflect around the first rotating rod 4 rotatably connected to it. After the mounting frame 5 is adjusted to the target tilt angle, the stepper motor 205 stops running. At this time, the position of the first slider 203 is fixed, and the mounting frame 5 and the granulation disc 9 above it are stably maintained at this tilt angle, thereby realizing the control of the granulation tilt angle and ensuring that the granulation conditions of different raw materials are met.

[0028] When the tilt angle detected by the tilt angle sensor 207 is less than the set value R1, the first tilt angle adjustment component 2 drives the lead screw 202 to rotate forward, and controls the tilt angle of the granulation disk 9 at R1. When the tilt angle detected by the tilt angle sensor 207 is greater than the set value R2, the first tilt angle adjustment component 2 drives the lead screw 202 to reverse and control the tilt angle of the granulation disk 9 to R2. When the tilt sensor detects that the tilt angle has reached the set value R3, the stepper motor 205 stops driving and simultaneously activates the braking device to fix the tilt angle at R3.

[0029] The braking device can be an electromagnetic brake. When the tilt sensor 207 detects that the angle has reached the set value R3, the control system cuts off the power supply to the electromagnetic coil. The brake spring pushes the brake disc to fit against the end face of the motor output shaft, locking the motor shaft through friction, thereby preventing the lead screw 202 from rotating and achieving tilt angle locking.

[0030] The tilt sensor 207 controls the granulation process by detecting the tilt angle. Before the raw material is formed, the tilt angle can be controlled at a small increment to increase the material contact rate and improve the forming efficiency; after the granules are formed, the tilt angle can be gradually increased so that the formed granules can be discharged smoothly.

[0031] The edge height adjustment assembly includes an electric push rod 8 fixed on the mounting frame 5. The electric push rod 8 is preferably of a small size. The power output end of the electric push rod 8 is connected to a retractable extended disc 10, which is slidably fitted with the granulation disc 9. The inner wall of the extended disc 10 fits snugly against the outer wall of the granulation disc 9, with a pre-existing sliding gap. Driven by the small electric push rod 8, the extended disc 10 can extend and retract radially along the granulation disc 9, achieving flexible control of the edge height of the granulation chamber. Simultaneously, the two employ a rotationally constrained sliding fit structure, meaning the extended disc 10 can only perform linear extension and retraction and will not rotate synchronously with the granulation disc 9. This ensures stable and controllable material containment during granulation, adapting to the preparation needs of different batches and particle sizes.

[0032] A displacement sensor 6 is installed on the arc-shaped support frame 15. By controlling the elongation of the extended disc 10, the electric push rod 8 is stopped and locked when the extended disc 10 reaches the set value L1. Before pellet formation, the side height of the disc 10 can be appropriately increased to increase the movement time of the pellets in the disc and increase the feeding amount. After pellet formation, the side height can be gradually reduced so that the formed pellets can be discharged smoothly.

[0033] The scraper assembly includes a crossbar fixedly mounted on an arc-shaped support frame 15. A scraper 11 is provided at the lower end of the crossbar. When the scraper 11 comes into contact with the rotating raw material, the crossbar rotates, which drives the scraper 11 to rotate, so that the raw materials are mixed more thoroughly.

[0034] Both sides of the scraper 11 are equipped with paddles, which can be made of flexible material, while the scraper 11 can be made of rigid material. The scraper 11 has an S-shaped design. Based on the material difference between the scraper body and the paddles, when the raw material rotates with the granulation disc 9 and collides with the scraper 11, it can be divided into three granulation zones with different functions: the upper flexible paddles can form a flexible barrier to the raw material, creating a retention zone. Newly formed small particles continue to mix and agglomerate with the raw material in this zone, gradually growing larger until the particle size exceeds the elastic limit of the paddles, at which point they enter the subsequent granulation process with the rotation of the disc; the middle rigid scraper body... The material forms a rigid barrier against the raw material, creating a direct-fall zone. The blocked material falls directly to the bottom of the disc and quickly merges with the bottom material, providing sufficient raw material for secondary particle agglomeration. The flexible paddles on the lower side guide the material after collision to fall obliquely into the bottom material area along its tangential direction, forming an oblique flying zone. This effectively increases the amount of material accumulated at the bottom and accelerates the adsorption and forming process of small particles. This three-zone design can orderly separate raw materials in different states, reduce mutual interference between raw materials at different stages, expand the effective granulation space, and ultimately achieve a dual improvement in granulation efficiency and particle quality.

[0035] Example 2: Based on Example 1, please participate... Figure 4 - Figure 5As shown, a parameterized disc granulation device for efficient preparation of different particle sizes also includes a drying and conveying assembly 13 rotatably disposed between the inner sidewalls of the U-shaped support frame 12. The drying and conveying assembly 13 is used to granulate the material inside the granulation disc 9 to the target particle size, and then slide out along its inclined circumferential edge under the combined action of gravity and centrifugal force, falling into the corresponding drying and conveying assembly 13. At the same time, the material is dried and conveyed to the screening assembly 14.

[0036] The drying conveying assembly 13 includes a conveyor frame 1301 rotatably disposed between the inner walls of a U-shaped support frame 12. Both ends of the conveyor frame 1301 are rotatably connected to the U-shaped support frame 12 via rotating shafts. A second tilt angle adjustment assembly 1302 is provided at the lower end of the conveyor frame 1301. The second tilt angle adjustment assembly 1302 has a similar structure to the first tilt angle adjustment assembly 2, both using a motor and a lead screw 202 to drive a slider to reciprocate. The slider drives a support rod 206 to push against the upper structure, thus achieving flexible angle adjustment. The second tilt angle adjustment assembly 1302 is used to adjust the tilt angle of the conveyor frame 1301. By lifting one end of the conveyor frame 1301, the conveyor frame 1301 rotates around the U-shaped support frame 12 via rotating shafts. The angle of the conveyor frame 1301 is adjustable between 15-25°, dynamically adjusting the tilt angle of the conveyor frame 1301 according to the particle size and viscosity of the produced product. Multiple second rotating rods 1303 are arranged between the inner sidewalls of the conveyor frame 1301. Conveying wheels 1304 are symmetrically arranged on the outer surfaces of each of the second rotating rods 1303. A common conveyor belt 1305 is sleeved between the multiple conveying wheels 1304. A heating plate 1306 is arranged inside the conveyor belt 1305 between the inner sidewalls of the conveyor frame 1301. The heating plate 1306 is an electrically heated structure; when energized, it generates heat energy, which is conducted through contact with the inner side of the conveyor belt 1305, transferring heat to the surface of the conveyor belt 1305. This continuously heats and dries the freshly overflowed granulated particles conveyed by the conveyor belt 1305, achieving particle solidification. The temperature of the heating plate 1306 is adjustable, allowing for flexible temperature adjustment based on the viscosity of the material to ensure product quality. The freshly overflowed particles are solidified by the drying and conveying assembly 13 and then subjected to vibration screening to ensure that the particles do not stick together during screening. A cover plate 1307 is provided at the upper end of the conveyor frame 1301. The cover plate 1307 allows for the circulation of hot air, which is beneficial for accelerating drying. One of the conveyor wheels 1304 passes through the conveyor frame 1301 and extends to the other end, where it is connected to a motor. The motor can rotate in both directions, and the material on the conveyor belt 1305 rolls down slowly by its own weight. Guide plates 1308 are symmetrically arranged at the upper end of the conveyor frame 1301 on the side near the granulation disc 9. The guide plates 1308 are used to guide the tangentially rolled product onto the conveyor belt 1305. Since the angle adjustment range of the granulation disc 9 is small, the tangentially rolled material will fall onto the conveyor belt 1305 directly or indirectly through the guide plates 1308.

[0037] In this embodiment, the tilt angle of the conveyor frame 1301 is dynamically adjusted within the range of 15-25° by the second tilt angle adjustment component 1302, which has the same structure as the first tilt angle adjustment component 2. This allows for flexible adaptation based on the particle size and material viscosity of the produced particles. A motor drives one of the conveyor wheels 1304 to rotate, simultaneously driving multiple second rotating rods 1303 and the conveyor belt 1305. The motor can also rotate in both directions. Combined with the tilt angle of the conveyor frame 1301, the newly formed particles sliding into the granulation disc 9 slowly roll down the conveyor belt 1305 under their own weight. The electric heating plate 1306 inside 305 generates heat energy after being powered on, and transfers the heat to the surface of the conveyor belt 1305 through heat conduction. The temperature of the heating plate 1306 can be adjusted as needed according to the viscosity of the material, and the particles in the conveying process are continuously heated to achieve solidification. At the same time, the cover plate 1307 at the upper end of the conveyor frame 1301 can realize the hot air circulation, further accelerating the drying of the particles. The dried and solidified particles are smoothly conveyed into the screening component 14, effectively avoiding the particle sticking during the subsequent vibration screening process and ensuring the smooth progress of the screening operation.

[0038] Please see Figure 6 - Figure 9 As shown, a screening component 14 is disposed on one side of the drying and conveying component 13 and is used to screen the dried product, enabling rapid separation of powder from the product. The screening component 14 includes a screening box 1401 disposed beside the conveyor frame 1301. A limiting groove 1402 is formed on the inner wall of the screening box 1401. Multiple first return springs 1403 are disposed at the bottom of the limiting groove 1402, and a rectangular frame 1404 is disposed at the upper end of the multiple first return springs 1403. The rectangular frame 1404 is movably engaged within the limiting groove 1402 and tightly fitted against the inner wall of the screening box 1401. A screen 1405 is detachably connected to the rectangular frame 1404. The screen 1405 can be quickly replaced. Different inclination angles of the granulation disc 9 result in different particle sizes of the produced product. The detachable connection between the screen 1405 and the rectangular frame 1404 facilitates rapid replacement of the screen 1405. The lower end of the screening box 1401 is provided with a conical discharge port 1406. The powder screened by the screen 1405 can fall into the collection box at the bottom through the conical discharge port 1406 for recycling. The bottom end of the rectangular frame 1404 is fixedly provided with a mounting plate 1407 by a cross support frame. The upper end of the mounting plate 1407 is provided with a vibration motor 1408. The output shaft of the vibration motor 1408 is provided with a cam 1409. The side walls of the rectangular frame 1404 are provided with a fixing plate 1410 that matches the cam 1409. The vibration motor 1408 drives the cam 1409 to rotate. The cam 1409 intermittently lifts the fixing plate 1410, thereby cooperating with the first return spring 1403 to realize the vibration screening of the screen 1405.

[0039] A conical discharge hopper 1411 is provided on one side of the screening box 1401. A through hole is provided on one side of the screening box 1401, and the through hole communicates with the conical discharge hopper 1411. A baffle 1412 is slidably installed on one side of the screening box 1401, and the baffle 1412 is used to block the through hole of the screening box 1401. A telescopic rod is provided inside one side of the screening box 1401. The upper end of the telescopic rod is connected to the top of the baffle 1412. The telescopic rod drives the baffle 1412 to move upward, causing the baffle 1412 to slide against the screening box 1401. The bottom end of the baffle 1412 no longer blocks the through hole, and the screening box 1401 communicates with the conical discharge hopper 1411. Therefore, the material inside the screening box 1401 enters the conical discharge hopper 1411 through the through hole. A material collection box can be connected to one end of the conical discharge hopper 1411 for unified product collection.

[0040] A push plate 1413 is provided on the other side of the screening box 1401. The push plate 1413 is embedded in the inner wall of the screening box 1401 and will not interfere with the movement of the screen 1405 when it vibrates up and down. A flat cylinder 1414 is provided on the outer wall of the screening box 1401. One end of the flat cylinder 1414 passes through the side wall of the screening box 1401 and is connected to the push plate 1413. The bottom end of the push plate 1413 is slightly higher than the height of the screen 1405 when it is in equilibrium and there is no material on top. After a batch of products has finished vibrating, the screen 1405 will be slightly lower than the equilibrium position. The flat cylinder 1414 drives the push plate 1413 to move forward, pushing the product from the through hole to the conical discharge hopper 1411.

[0041] The bottom height of the push plate 1413 is designed for calibration. Its reference is matched with the working condition of the screen 1405. The upper surface of the screen 1405 bearing the maximum screening weight of a single batch and compressed by gravity to the first return spring 1403 is used as a reference. The bottom of the push plate 1413 is moved up a little distance (3 to 5 cm calibration) on this basis. This design is adapted to the single-batch rated feeding requirements of screen 1405. When screen 1405 is carrying material, it is in contact with the bottom end of push plate 1413. After cam 1409 stops rotating, screen 1405 is no longer subject to the intermittent lifting force of cam 1409, but only to the weight of the material and the elastic support force of the first return spring 1403. Under the balance of the two forces, screen 1405 maintains a static state of maximum compression and downward movement. At this time, flat cylinder 1414 drives push plate 1413 to move forward towards conical discharge hopper 1411. The bottom end of push plate 1413 is in contact with screen surface to form a complete pushing surface, pushing qualified particles to the through hole of screening box 1401 and discharged through conical discharge hopper 1411, realizing the orderly discharge of each batch of material. After the weight sensor detects the threshold, it first shuts down the granulation disc 9 and the drying conveyor assembly 13. Once all the remaining particles on the drying conveyor assembly 13 have slid into the screen 1405 and the weight of the screen 1405 has stabilized at the maximum threshold, it then controls the cam 1409 to stop rotating, allowing the screen 1405 to enter a stable, stationary state. The weight sensor is located at the contact point between the bottom of the rectangular frame 1404 and the upper end of the first return spring 1403; the model can be an LCS-M01 miniature pressure load sensor.

[0042] Please see Figure 10 - Figure 11 As shown, a first upright arc groove 1415 is symmetrically formed at the upper end of the rectangular frame 1404, and a circular groove 1416 is formed at the bottom end of the first upright arc groove 1415. Inside the rectangular frame 1404, a second upright arc groove 1417 perpendicular to the first upright arc groove 1415 is formed at the top of the circular groove 1416. A sleeve 1418 is symmetrically rotatably mounted on the upper end of the screen 1405. A sleeve rod 1419 is slidably engaged inside the sleeve rod 1419. The lower end of the sleeve rod 1419 extends to the outside of the sleeve 1418 and is fixedly mounted with an upright disc 1420. The upright disc 1420 is adapted to the first upright arc groove 1415 and the second upright arc groove 1417. A second return spring 1421 is sleeved on the outer surface of the sleeve rod 1419 and disposed between the sleeve 1418 and the upright disc 1420. A pressing rod is provided at the upper end of the sleeve 1418.

[0043] During installation, press the pressing rod to retract the sleeve rod 1419, compressing the second return spring 1421. Align the upright disc 1420 with the first upright arc groove 1415 and insert it downwards into the circular groove 1416. Rotate the sleeve rod 1419 to rotate the upright disc 1420 into the vertical second upright arc groove 1417. After releasing the pressing rod, the second return spring 1421 rebounds and pushes the upright disc 1420, making it tightly locked in the second upright arc groove 1417, thus fixing the screen 1405. During disassembly, press the pressing rod again to compress the second return spring 1421, and rotate the sleeve rod 1419 in the opposite direction to rotate the upright disc 1420 back through the circular groove 1416 to the first upright arc groove 1415. Pull it upwards to quickly remove the screen 1405, adapting to the replacement needs of screens 1405 for different particle sizes.
