Abstract
Description
Technical Field
[0001] This utility model relates to the field of disc granulator technology, specifically to a large-diameter ball stirring, screening and rejection device for disc granulators. Background Technology
[0002] Disc granulators are widely used in industries such as chemical, pharmaceutical, food, and environmental protection. In the chemical industry, they are used for granulation of materials such as plastics, resins, and fertilizers; in the pharmaceutical industry, they are used for the preparation of granules for traditional Chinese medicine and Western medicine; and in the food industry, they are used for the production of food additives, seasonings, and other products.
[0003] Traditional disc granulators primarily separate particles of different sizes through the rotation of a disc and subsequent screening equipment. Particles discharged from the disc enter the screening equipment, such as a vibrating screen. Small particles continue to roll on the disc, constantly absorbing new material and gradually increasing in size until they reach a suitable size and detach from the disc. The screening equipment typically has screens with different aperture sizes. When particles pass through the screen, small particles smaller than the screen aperture will pass through and fall, becoming undersize particles; particles that meet the size requirements will remain on the screen and be collected as qualified products; while large particles larger than the screen aperture will be blocked by the screen and discharged from one end, allowing them to be returned to the granulator for re-granulation.
[0004] However, in the aforementioned traditional devices, after the particles reach a suitable size during the screening process, they detach from the disc and pass through a screen. The presence of large particles leads to uneven particle size, and the movement of large particles within the disc may interfere with the normal granulation process, affecting the formation and growth of smaller particles and reducing the overall pelletizing rate. Removing large particles helps maintain a stable granulation environment within the granulator, improving granulation efficiency and equipment capacity. Currently available disc granulator large-diameter particle mixing and screening removal devices are either complex in structure, expensive, or unable to quickly identify and remove all large particles. Utility Model Content
[0005] To solve the above problems, this utility model provides a large-diameter ball stirring, screening and rejection device for a disc granulator. This utility model is achieved through the following technical solution.
[0006] A large-diameter ball mixing and screening device for a disc granulator includes a base plate. A frame is fixedly connected to the center of the top surface of the base plate. A fixed plate is rotatably connected to the center of the top surface of the frame. A motor is fixedly connected to the side of the fixed plate. A support base is fixedly connected to the top of the fixed plate. The output end of the motor passes through the axis of the support base and is fixedly connected to a disc. The support base is rotatably connected to the disc. An adjustment assembly is provided at the bottom of the fixed plate. A bracket is fixedly connected to the left side of the top surface of the base plate. The device also includes:
[0007] An angle adjustment mechanism is installed on the top and bottom surfaces of the bracket;
[0008] A screening and conveying mechanism is used to screen out large-diameter balls formed during the operation of the disc granulator;
[0009] A drive mechanism is provided to drive the screening and conveying mechanism.
[0010] As a further embodiment of this utility model, the adjusting assembly includes a primary hydraulic telescopic rod, a connecting plate is fixedly connected to the bottom of the fixed plate, the primary hydraulic telescopic rod is hinged at the axis of the connecting plate, and the bottom of the primary hydraulic telescopic rod is hinged to the bottom top surface of the frame.
[0011] As a further embodiment of this utility model, the angle adjustment mechanism includes a screening barrel, a primary support rod is hinged to the front right side of the bottom surface of the support, a secondary hydraulic telescopic rod is hinged to the outer wall of the primary support rod, the secondary hydraulic telescopic rod is hinged to the bottom of the support, a secondary support rod is hinged to the back right side of the bottom surface of the support, the screening barrel is in the shape of a "semi-cylindrical", the arc apex of the end face of the screening barrel is hinged to the bottom of the primary support rod, one end of the semi-circular diameter of the end face of the screening barrel is hinged to the secondary support rod, and screening baffles are fixed to both sides of the bottom surface of the screening barrel.
[0012] As a further embodiment of this utility model, the top of the screening barrel is provided with a screening groove, and two sets of the primary support rod, the secondary hydraulic telescopic rod and the secondary support rod are provided and symmetrically distributed at the top of both ends of the screening barrel. The central axis of the screening barrel is kept horizontal and the bottom surface of the screening barrel is parallel to the top surface of the disc. The screening baffle is inclined to the top surface of the disc.
[0013] As a further embodiment of this utility model, the screening and conveying mechanism includes stirring blades, and rotating sleeves are fixedly connected to the shafts at both ends of the screening barrel. The inner walls of the two rotating sleeves are rotatably connected to a rotating shaft, and stirring blades are fixedly connected to the outer wall of the rotating shaft. The stirring blades are L-shaped and are arranged in multiple sets in a spiral pattern.
[0014] As a further embodiment of this utility model, the driving mechanism includes a chain, a transmission sprocket is fixedly connected to one end of the rotating shaft away from the bracket, a drive sprocket is provided at the bottom of the transmission sprocket, the transmission sprocket and the drive sprocket are connected by chain transmission, a reduction motor is provided on the side of the drive sprocket, and the output end of the reduction motor is fixedly connected to a transmission shaft provided at the center of the drive sprocket shaft.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. The rotation angle of the fixed plate is adjusted by using the first-level hydraulic telescopic rod, which in turn drives the disc to adjust its tilt angle. The motor is started, and the output end of the motor drives the disc to rotate. The raw materials are placed into the disc in equal amounts multiple times, and some liquid is added at the same time.

The clumps move eccentrically on the inner wall of the disc, which plays the role of mixing and forming clumps.
[0017] 2. The two secondary hydraulic telescopic rods on both sides extend synchronously, driving the primary support rod to swing around the top of the primary support rod to a suitable position, so that the bottom surface of the screening barrel is parallel to the top surface of the disc. The secondary hydraulic telescopic rod drives the primary support rod to swing, and the screening barrel always rotates around the axis of the screening barrel, so that the bottom screening baffle abuts against the top surface of the disc, allowing clumps to enter the interior of the screening barrel through the bottom screening baffle. Small clumps are screened out from the side of the screening baffle and the screening groove at the top of the screening barrel and continue to perform eccentric motion.
[0018] 3. The output of the geared motor drives the drive sprocket to rotate, which in turn drives the transmission sprocket to rotate, causing the shaft inside the screening barrel to rotate and the stirring blades to rotate. As a result, small clumps inside the screening barrel move from the gaps between the stirring blades to the outside of the screening barrel and continue to move eccentrically on the top surface of the disc. Large clumps are conveyed to the end near the transmission sprocket inside the screening barrel by the rotation of the stirring blades and are discharged from the bottom of the screening barrel near the transmission sprocket, thus achieving the function of screening and removal.

[0029] like Figure 1-3 As shown, this utility model has the following three specific embodiments.
[0030] Example 1
[0031] A large-diameter ball mixing and screening device for a disc granulator includes a base plate 11, a frame 12 fixedly connected to the center of the top surface of the base plate 11, a fixed plate 13 rotatably connected to the center of the top surface of the frame 12, a motor 14 fixedly connected to the side of the fixed plate 13, a support base 15 fixedly connected to the top of the fixed plate 13, the output end of the motor 14 passing through the axis of the support base 15 and fixedly connected to a disc 16, the support base 15 and the disc 16 being rotatably connected, an adjustment assembly provided at the bottom of the fixed plate 13, and a bracket 17 fixedly connected to the left side of the top surface of the base plate 11. The device also includes:
[0032] Angle adjustment mechanism 2 is installed on the top and bottom surfaces of bracket 17;
[0033] Screening and conveying mechanism 3 is used to screen out large-diameter balls formed during the operation of the disc granulator;
[0034] Drive mechanism 4 is used to drive the screening and conveying mechanism 3.
[0035] The adjustment assembly includes a primary hydraulic telescopic rod 132, a connecting plate 131 fixed to the bottom of the fixed plate 13, the primary hydraulic telescopic rod 132 hinged at the axis of the connecting plate 131, and the bottom of the primary hydraulic telescopic rod 132 hinged to the bottom top surface of the frame 12.
[0036] In this embodiment, as Figure 1 and Figure 2As shown, the rotation angle of the fixed plate 13 is adjusted by the first-stage hydraulic telescopic rod 132, thereby driving the disc 16 to adjust its tilt angle. The motor 14 is started, and the output end of the motor 14 drives the disc 16 to rotate. The raw materials are placed inside the disc 16 in equal amounts multiple times, and some liquid is added at the same time. The centrifugal force of the disc 16 when it rotates makes the liquid and raw materials mix to form clumps of different sizes, and they move eccentrically on the inner wall of the disc 16, which plays the role of mixing and forming clumps. The angle adjustment mechanism 2 is used to adjust the angle of the screening barrel 24 to match the angle of the disc 16. The drive mechanism 4 drives the screening and conveying mechanism 3 to screen and remove the clumps of different sizes.
[0037] Example 2
[0038] The difference from Embodiment 1 is that this embodiment discloses an angle adjustment mechanism:
[0039] The angle adjustment mechanism 2 includes a screening barrel 24. A primary support rod 21 is hinged to the front right side of the bottom surface of the support 17. A secondary hydraulic telescopic rod 22 is hinged to the outer wall of the primary support rod 21. The secondary hydraulic telescopic rod 22 is hinged to the bottom of the support 17. A secondary support rod 23 is hinged to the back right side of the bottom surface of the support 17. The screening barrel 24 is semi-cylindrical. The arc top of the end face of the screening barrel 24 is hinged to the bottom of the primary support rod 21. One end of the semi-circular diameter of the end face of the screening barrel 24 is hinged to the secondary support rod 23. Screening baffles 25 are fixed to both sides of the bottom surface of the screening barrel 24.
[0040] Preferably, the top of the screening barrel 24 is provided with a screening groove, and two sets of primary support rod 21, secondary hydraulic telescopic rod 22 and secondary support rod 23 are provided and symmetrically distributed at the top of both ends of the screening barrel 24. The central axis of the screening barrel 24 is kept horizontal and the bottom surface of the screening barrel 24 is parallel to the top surface of the disc 16. The screening baffle 25 is inclined to the top surface of the disc 16.
[0041] In this embodiment, as Figure 2 As shown, the two secondary hydraulic telescopic rods 22 extend synchronously on both sides, driving the primary support rod 21 to swing around the top of the primary support rod 21 to a suitable position, so that the bottom surface of the screening barrel 24 is parallel to the top surface of the disc 16. The secondary hydraulic telescopic rods 22 drive the primary support rod 21 to swing, and the screening barrel 24 always rotates around the axis of the screening barrel 24, so that the bottom screening baffle 25 abuts against the top surface of the disc 16, so that the clumps enter the interior of the screening barrel 24 through the bottom screening baffle 25, and the small clumps are screened out from the side of the screening baffle 25 and the screening groove at the top of the screening barrel 24 and continue to make eccentric motion.
[0042] Example 3
[0043] The difference from Embodiment 2 is that this embodiment discloses a screening and conveying mechanism and a driving mechanism:
[0044] The screening and conveying mechanism 3 includes stirring blades 32. Rotating sleeves 31 are fixedly connected to the shafts at both ends of the screening barrel 24. Rotating shafts are rotatably connected to the inner walls of the two rotating sleeves 31. Stirring blades 32 are fixedly connected to the outer walls of the rotating shafts. The stirring blades 32 are "L" shaped and have multiple sets arranged in a spiral pattern.
[0045] Preferably, the drive mechanism 4 includes a chain 43, a drive sprocket 41 is fixedly connected to one end of the shaft away from the bracket 17, a drive sprocket 42 is provided at the bottom of the drive sprocket 41, the drive sprocket 41 and the drive sprocket 42 are connected by the chain 43, a reduction motor 44 is provided on the side of the drive sprocket 42, and the output end of the reduction motor 44 is fixedly connected to the drive shaft provided at the center of the drive sprocket 42.
[0046] In this embodiment, as Figure 3 As shown, the output of the geared motor 44 drives the drive sprocket 42 to rotate, which in turn drives the transmission sprocket 41 to rotate via the chain 43. This drives the rotating shaft inside the screening barrel 24 to rotate, which in turn drives the stirring blades 32 to rotate. As a result, small clumps inside the screening barrel 24 move from the gaps between the stirring blades 32 to the outside of the screening barrel 24 and continue to move eccentrically on the top surface of the disc 16. Large clumps inside the screening barrel 24 are conveyed to the end near the transmission sprocket 41 by the rotation of the stirring blades 32 and are discharged from the bottom of the screening barrel 24 near the transmission sprocket 41, thus achieving the function of screening and removing clumps.
[0047] The working principle of this utility model is as follows:
[0048] The rotation angle of the fixed plate 13 is adjusted by using the first-stage hydraulic telescopic rod 132, thereby driving the disc 16 to adjust its tilt angle. The motor 14 is started, and the output end of the motor 14 drives the disc 16 to rotate. The raw material is placed into the disc 16 in equal amounts multiple times, and some liquid is added at the same time. The centrifugal force of the disc 16 when it rotates causes the liquid and raw material to mix and form clumps of different sizes. The clumps move eccentrically on the inner wall of the disc 16, which plays a role in mixing and forming clumps. The second-stage hydraulic telescopic rods 22 on both sides extend synchronously, driving the first-stage support rod 21 to swing around the top of the first-stage support rod 21 to a suitable position, so that the bottom surface of the screening barrel 24 is parallel to the top surface of the disc 16. The second-stage hydraulic telescopic rods 22 drive the first-stage support rod 21 to swing. The screening barrel 24 always rotates around the axis of the screening barrel 24, so that the bottom screening baffle 25 abuts against the top surface of the disc 16, allowing the clumps to enter the interior of the screening barrel 24 through the bottom screening baffle 25. The output of the geared motor 44 drives the drive sprocket 42 to rotate, which in turn drives the transmission sprocket 41 to rotate via the chain 43. This drives the rotating shaft inside the screening barrel 24 to rotate, which in turn drives the stirring blades 32 to rotate. As a result, small clumps inside the screening barrel 24 move from the gaps between the stirring blades 32 to the outside of the screening barrel 24 and continue to move eccentrically on the top surface of the disc 16. Large clumps inside the screening barrel 24 are conveyed to the end near the transmission sprocket 41 by the rotation of the stirring blades 32 and are discharged from the bottom of the screening barrel 24 near the transmission sprocket 41, thus achieving the function of screening and removing clumps.
[0049] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
