Description

Technical Field

[0001] This invention relates to the field of raw material pretreatment technology for granulation equipment, specifically to a granulation equipment for the production of defoaming masterbatch. Background Technology

[0002] In patent application CN221717477U, a material cylinder is included. A granulation plate and a mixing tank are connected and installed on the side wall of the material cylinder. A dust cover is fixedly installed on the upper surface of the material cylinder. A conveying motor is fixedly installed on the other side wall of the material cylinder through a fixed cover. A screw rod is fixedly installed at the output end of the conveying motor. One end of the screw rod is rotatably connected to the side wall of the granulation plate. A granulation component is provided on the inner wall of the dust cover. In this application, by providing a granulation component, based on the principle that the rotation of the small gear driving the large gear can reduce the speed, the rotation of the scraper rod will be reduced as needed, thereby changing the size of the PE particles. Automatic granulation is achieved by extruding and cutting the raw materials. At the same time, the cutting rate can be changed according to different needs to change the size of the PE particles, which can effectively improve the applicability of the equipment and thus improve the practicality of the device.

[0003] In the aforementioned patent, during the production of defoaming masterbatch, the performance of the granulation equipment directly affects the uniformity, purity, and final quality of the product. Although some existing granulation equipment has basic extrusion, cutting, and granulation functions, there are still significant deficiencies in the raw material pretreatment stage. In particular, the ability to handle dust, fine impurities, and agglomerated materials formed due to moisture absorption or static electricity mixed in the raw materials is limited. If these impurities and agglomerated materials directly enter the extruder, it will not only lead to uneven melting and the generation of "raw material" or crystal point defects, but may also clog the die head filter, affecting the continuity of production and product consistency, and thus affecting product quality. Summary of the Invention

[0013] Preferably, the spiral plate has an air passage inside, and the spiral plate has multiple air extraction holes, with a filter screen inside each air extraction hole.

[0014] Preferably, the agglomeration component includes a fixing block fixedly connected to one end of the spiral plate. The fixing block has a material leakage chamber, and a material inlet is opened on one side of the fixing block. The position of the material inlet corresponds to the spiral plate. An installation groove is opened below one side of the material leakage chamber. A grid is fixedly connected to one side of the installation groove. Multiple connecting air ducts are fixedly connected inside the fixing block. Multiple extrusion plates corresponding to extrusion rods are fixedly connected to the lower end of the fixing block.

Multiple air inlet holes are opened on one side of the second connecting pipe.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0016] (1) The conical storage hopper is equipped with a fixing component, a cleaning component, a connecting component, a driving component, and a rotating component. Through the pretreatment mechanism, continuous cleaning and pretreatment of materials are achieved. This effect is reflected in two closely connected links. First, when the material falls onto the rotating spiral plate, its rolling process exposes the light dust and impurities entrained inside. At this time, the stable negative pressure airflow generated by the air pump in the fixed shell passes through the connecting bend, groove, connecting slot, first connecting pipe, and connecting air duct, and finally acts on the air passage of the spiral plate, and draws in external air from the air extraction hole. This airflow can accurately extract the exposed dust and fine impurities when the material rolls, and finally collect them in the connecting shell through the entire air path system, where they are intercepted by the ventilation net. The material undergoes initial air separation and dust removal, and the entire process is dynamic, continuous, and automated, greatly improving cleaning efficiency. Secondly, the pre-cleaned material continues to fall along the spiral plate and enters the discharge chamber of the agglomeration component. Here, the negative pressure suction effect continuously acts on the falling material flow through the second connecting pipe. During the fall, the material becomes loose due to weightlessness, and the gaps between particles increase. At this time, the negative pressure airflow can more effectively penetrate the material layer and forcefully suck away the dust that was not removed in the previous stage and the newly generated debris due to friction, completing the deep secondary cleaning. This two-stage series negative pressure dust removal mechanism ensures that the material entering the extruder has extremely high cleanliness and effectively avoids the formation of crystal points or defects by impurities during the high-temperature melting process.

[0017] (2) Through the coordinated operation of the agglomeration component and the fixing component, the deeply cleaned material finally falls through the leakage chamber onto the barrier net fixed in the fixed barrel. The barrier net only allows dispersed single or small particles to pass through, while any large clumps formed due to agglomeration will be effectively intercepted on the net surface. At this time, the drive motor continuously drives the vertical rod and the entire pretreatment mechanism connected to it to rotate at a constant speed through the drive component. The stationary extrusion rod and the continuously rotating extrusion plate generate continuous relative motion. When an agglomerated material is pushed into the narrow space between the two stationary extrusion rods by the moving extrusion plate, it will be subjected to huge force. The combined action of shearing and extrusion forces effectively crushes and disperses the material into fine particles that meet the requirements. This process is continuous and mandatory, ensuring that all clumps that fail to pass through the barrier are processed one by one without any omissions. The crushed material can then pass smoothly through the barrier and enter the conical storage tank and extruder below. This structure completely prevents unmelted material from clumping into the extruder, ensuring that all materials undergo consistent heating, shearing, and melting processes in the screw melting section. This solves serious quality problems that may occur in the masterbatch product due to uneven melting, such as "raw material," poor plasticization, performance fluctuations, and even clogging of the die head filter.

[0040] The spiral plate 32 has an air passage 321 inside and multiple air extraction holes 322 on the spiral plate 32. A filter screen is installed inside the air extraction hole 322. The outer side of the spiral plate 32 is in contact with the inner wall of the connecting barrel 231.

[0041] The agglomeration component 33 includes a fixing block 331 fixedly connected to one lower end of the spiral plate 32. The fixing block 331 has a material leakage chamber 332. A material inlet 333 is provided on one side of the fixing block 331, its position corresponding to the spiral plate 32. An installation groove 334 is provided below one side of the material leakage chamber 332. A grid 335 is fixedly connected to one side of the installation groove 334. Multiple connecting air ducts 336 are fixedly connected inside the fixing block 331. Multiple extrusion plates 337 corresponding to the extrusion rod 214 are fixedly connected to the lower end of the fixing block 331. A material leakage chamber 334 is provided on one side of the fixing block 331. The mounting hole is fixedly connected to a first connecting pipe 338 and a second connecting pipe 339. The first connecting pipe 338 is fixed above the second connecting pipe 339. The fixing block 331 is fixedly connected to the connecting ring 251. The connecting groove 252 corresponds to the positions of the first connecting pipe 338 and the second connecting pipe 339. The first connecting pipe 338 is fixedly connected to multiple connecting air ducts 336. The connecting air ducts 336 are connected to the first connecting pipe 338. The other end of the connecting air duct 336 is connected to the air passage 321. Multiple air inlet holes are opened on one side of the second connecting pipe 339.

[0042] The working principle of this invention is as follows: During the operation of the equipment, the material enters the connecting barrel 231 from the conveying equipment and falls onto the fan-shaped disk 31. The drive motor 244 drives the second rotating disk 245 to rotate. The second rotating disk 245 drives the first rotating disk 242 to rotate through the rotating belt 246. The first rotating disk 242 drives the vertical rod 241 to rotate. The vertical rod 241 drives the fan-shaped disk 31 and the spiral plate 32 to rotate. The rotation of the fan-shaped disk 31 and the spiral plate 32 causes the material to fall. As the material rotates with the spiral plate 32, it rolls on the spiral plate 32. The impurities and dust in the material fall directly into the air passage 321 from the filter screen on the air extraction hole 322.

[0043] The fan inside the fixed housing 224 draws gas from the groove 222 through the connecting bend 223. The gas in the air duct 321 enters the groove 222 through the connecting duct 336, the first connecting pipe 338, and the connecting slot 252, and is drawn out by the fan inside the fixed housing 224. External air enters the air duct 321 through the air extraction hole 322. During this process, dust and impurities in the material are carried into the air duct 321 and discharged into the connecting housing 226 by the air pump inside the fixed housing 224. The ventilation net 228 traps the dust and impurities in the connecting housing 226. Meanwhile, as the material on the spiral plate 32 continues to move down along the inclined surface of the spiral plate 32, it falls from the spiral plate 32 into the leakage chamber 332. The fan in the fixed shell 224 draws the gas in the mounting groove 334 through the connecting bend 223, groove 222, connecting through groove 252 and the second connecting pipe 339. When the material falls into the leakage chamber 332, the gap between the materials becomes larger. The fan draws the air in the leakage chamber 332 through the mounting groove 334, and at the same time carries away the dust and impurities in the material falling into the leakage chamber 332 and discharges them into the connecting shell 226.

[0044] When material falls from the discharge chamber 332 onto the barrier net 213, unclumped material falls directly from the barrier net 213 into the conical storage tank 13, while clumped material is blocked by the barrier net 213. As the spiral plate 32 drives the fixed block 331 to rotate, and the fixed block 331 drives the extrusion plate 337 to rotate on the barrier net 213, the fixed block 331, through the discharge chamber 332 and the extrusion plate 337, moves the clumped material falling on the barrier net 213. When the clumped material is located between the two extrusion rods 214, the moving extrusion plate 337 and the stationary extrusion rods 214 move relative to each other, shearing the clumped material and breaking it up. This prevents uneven melting of the clumped material in the extruder, which would reduce product quality.

The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
