[0001] This utility model belongs to the field of screening technology, specifically relating to a multi-stage particle screening device for an antioxidant swing granulator. Background Technology
[0002] In the production of antioxidants, the granules obtained by the swing granulator typically need to be graded according to particle size. Currently, the industry commonly uses manual screening, which has significant technical drawbacks: operators need to screen the granulated material multiple times, each time only separating a single particle size, resulting in low screening efficiency; moreover, repeated operations not only increase labor costs but also easily affect the product grading accuracy due to operational errors. Especially when processing large batches of materials, this intermittent screening method severely restricts production efficiency and cannot meet the needs of modern continuous production; therefore, existing antioxidant grading and screening technologies suffer from poor continuity and low work efficiency.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0035] An embodiment of a multi-stage particle screening device for an antioxidant oscillating granulator is described herein with reference to Figures 1 to 5. Specifically, the multi-stage particle screening device for the antioxidant oscillating granulator is constructed as a split structure, comprising a cylinder 100, a fixed ring 201, a sieve disc 202, sieve holes 203, an elastic element 204, a sliding shaft 300, a lifting part 400, and a telescopic part 500. The lifting part 400 drives the sliding shaft 300 to move downward, which in turn drives the telescopic part 500 and each sieve disc 202 to move downward. The sieve discs 202 compress the elastic element 204. When the telescopic part 500 retracts to the inner side of the sliding shaft 300, it releases the sieve discs 202. At this time, under the elastic force of the elastic element 204, the sieve discs 202... 2. The device pops upward and vibrates with the elastic extension and contraction of the elastic element 204, screening the antioxidant particles on the screen plate 202. Particles with a diameter smaller than the diameter of the sieve hole 203 in the corresponding screening unit move downward. When the screen plate 202 stops vibrating, the drive shaft 300 moves upward to reset, and the extension part 500 extends out of the peripheral wall of the slide shaft 300 again. Then, the above compression-release is repeated continuously to fully screen the particles on each layer of screen plate 202, realizing a multi-stage screening process for antioxidant particles. Multiple screening units work synchronously, effectively improving screening efficiency and screening continuity.
[0036] Please refer to Figures 1 to 5 for the multi-stage particle screening device of the antioxidant swing granulator, which includes a vertically placed cylinder 100.
[0037] The upper end of the cylinder 100 is provided with a feed inlet 101;
[0038] Multiple sets of screening units are arranged inside the cylinder 100 along its own axis.
[0039] Each screening unit includes a fixing ring 201 and a sieve plate 202. The fixing ring 201 and the sieve plate 202 are placed coaxially with the cylinder 100. The sieve plate 202 is located above the fixing ring 201. The fixing ring 201 is fixed to the inner peripheral wall of the cylinder 100. The sieve plate 202 is slidably connected to the inner wall of the cylinder 100. The sieve plate 202 is provided with multiple sieve holes 203. The fixing ring 201 and the sieve plate 202 are connected by multiple elastic elements 204 evenly distributed in a ring.
[0040] The diameter of the sieve holes 203 in each screening unit gradually decreases from the upper end to the lower end of the cylinder 100;
[0041] The cylinder 100 is provided with a sliding shaft 300 placed coaxially, and each screen plate 202 is slidably sleeved on the sliding shaft 300. The cylinder 100 is provided with a lifting part 400 for driving the sliding shaft 300 to rise and fall.
[0042] The sliding shaft 300 is provided with multiple sets of telescopic parts 500. The number of telescopic parts 500 is equal to that of the sieve plate 202 and they correspond one to one. The telescopic parts 500 are all located above the corresponding sieve plate 202. The ends of the telescopic parts 500 that are away from the central axis of the sliding shaft 300 can extend radially to the outer side of the peripheral wall of the sliding shaft 300.
[0043] Using the method described above, antioxidant granules produced by the oscillating granulator are injected into the cylinder 100 through the feed inlet 101. The antioxidant granules fall onto the uppermost screening unit. The telescopic part 500 is opened, extending the end of the telescopic part 500 away from the central axis of the sliding shaft 300 to the outer side of the peripheral wall of the sliding shaft 300. Then, the lifting part 400 drives the sliding shaft 300 to move downward. The sliding shaft 300 drives the telescopic part 500 and each screen plate 202 to move downward. The screen plates 202 compress the elastic element 204. After the elastic element 204 is fully compressed, the telescopic part 500 retracts to the inner side of the peripheral wall of the sliding shaft 300 to release the screen plates 202. At this time, the elastic element 204 springs back. Under the action of force, the sieve disc 202 pops upward and vibrates with the elastic extension and contraction of the elastic element 204, screening the antioxidant particles on the sieve disc 202, so that particles with a diameter smaller than the diameter of the sieve hole 203 in the corresponding screening unit move downward; when the sieve disc 202 stops vibrating, the drive shaft 300 moves upward to reset, and the extension part 500 extends out of the peripheral wall of the slide shaft 300 again, and then the above compression-release is repeated continuously, so that the particles on each layer of sieve disc 202 are fully screened, realizing a multi-stage screening process for antioxidant particles, and multiple screening units work synchronously, effectively improving screening efficiency and screening continuity;
[0044] Meanwhile, the strong vibration generated by the compression and release of the elastic element 204 can effectively reduce the problem of antioxidant particles clogging at the sieve holes 203.
[0045] To facilitate the removal of antioxidant particles from each sieve disc 202 after screening, multiple discharge ports 102 are provided on the circumferential wall of the cylinder 100 along its own axis, with one more discharge port 102 than the number of sieve discs 202.
[0046] The bottom discharge port 102 is located below each screen plate 202;
[0047] The remaining discharge ports 102 correspond one-to-one with each screen plate 202, and each discharge port 102 is located above its corresponding screen plate 202.
[0048] Each discharge port 102 is equipped with a sealing plate 103. The inner side wall of the sealing plate 103 is flush with the inner peripheral wall of the cylinder 100. The sealing plate 103 is rotatably hinged to one side of the discharge port 102 through a hinge.
[0049] Preferably, the hinge can be used as the hinge component;
[0050] Preferably, an elastic sealing strip is provided on the side of the discharge port 102 away from the hinge, so that the sealing plate 103 can always be kept closed without external force.
[0051] The bottom outlet 102 is used to remove the smallest antioxidant particles from the bottom of the cylinder 100, and the other outlets 102 are used to remove antioxidant particles of the corresponding size from the corresponding sieve discs 202.
[0052] The lifting unit 400 includes a first telescopic cylinder that is vertically fixed to the top or bottom surface of the inner side of the cylinder 100. The output end of the first telescopic cylinder is fixed to one end of the slide shaft 300. By opening the first telescopic cylinder, the slide shaft 300 can be automatically driven to move up and down.
[0053] Each telescopic part 500 includes a plurality of second telescopic cylinders 501 that are evenly distributed in a ring around the central axis of the sliding shaft 300. The second telescopic cylinders 501 are arranged radially along the sliding shaft 300. Each output end of the second telescopic cylinder 501 is fixedly connected to a pressure block 502, which is located at the end of the second telescopic cylinder 501 away from the central axis of the sliding shaft 300.
[0054] Multiple mounting slots 301 are provided on the periphery of the sliding shaft 300. The number of mounting slots 301 is equal to that of the second telescopic cylinders 501 and they correspond one-to-one. The second telescopic cylinders 501 are all installed in the corresponding mounting slots 301, and the pressure blocks 502 are all slidably connected to the mounting slots 301.
[0055] When it is necessary to move the screen plate 202 down, the output end of the second telescopic cylinder 501 drives the pressure block 502 to extend to the outside of the mounting groove 301. When the lifting part 400 drives the sliding shaft 300 down, the pressure block 502 drives the screen plate 202 down.
[0056] Preferably, the periphery of the pressure block 502 fits into the periphery of the mounting groove 301, which can prevent antioxidant particles from entering the mounting groove 301.
[0057] Each elastic element 204 includes a vertically placed telescopic rod 2041. The upper and lower ends of the telescopic rod 2041 are fixed to the sieve plate 202 and the fixing ring 201, respectively. The telescopic rod 2041 is hollow inside and both the upper and lower ends of the telescopic rod 2041 are sealed. A spring 2042 is provided inside the telescopic rod 2041. The two ends of the spring 2042 are fixed to the top and bottom surfaces of the inner side of the telescopic rod 2041, respectively.
[0058] Without affecting the extension and retraction of the spring 2042, the installation of the telescopic rod 2041 can prevent antioxidant particles from entering the spring 2042;
[0059] Preferably, the telescopic rod 2041 includes a first sleeve vertically fixed to the upper end of the fixing ring 201, the upper end of the first sleeve being open, a second sleeve slidably connected to the first sleeve and placed coaxially, the lower end of the second sleeve being open, one end of the spring 2042 being fixed to the inner bottom surface of the first sleeve, and the other end of the spring 2042 being fixed to the inner top surface of the second sleeve, a vertically placed sliding groove being provided on the outer wall of the second sleeve, the sliding groove penetrating the lower end of the second sleeve, a protrusion being fixed on the first sleeve, the protrusion being slidably connected in the sliding groove; this can improve the guiding nature of the lifting and lowering movement of the second sleeve, and at the same time prevent the separation of the second sleeve from the first sleeve.
[0060] Preferably, the portion of the retaining ring 201 located between two adjacent elastic members 204 can be cut off to reduce the amount of antioxidant particles falling onto the retaining ring 201.
[0061] The feed inlets 101 are arranged in a ring and evenly distributed around the central axis of the cylinder 100. Antioxidant particles are injected into the cylinder 100 from the multiple feed inlets 101, which can prevent the antioxidant particles entering the cylinder 100 from accumulating on one side of the screen 202 and improve the uniformity of the distribution of antioxidant particles on the screen 202.
[0062] Each feed inlet 101 is fixed with a feed funnel 104; the upper diameter of the feed funnel 104 is larger than the lower diameter, so as to facilitate the injection of antioxidant particles into the cylinder 100.
[0063] Handles are fixed on the outer side wall of the sealing plate 103 to facilitate pulling the sealing plate 103 to rotate around the hinge.
