Abstract
The invention discloses a thermo-setting plastic pelleting method and a thermo-setting plastic pelleting device. The pelleting method comprises the steps of charging, extrusion feeding, pelleting by scraping, discharging by air blow and the like. The pelleting device comprises a charge port, a squeeze roller, a pelleting drum, a cold air blowing device, an inner wall scraper, an outer wall scraper and the like, wherein the pelleting drum is externally tangential to the circumference of the squeeze roller, and the pelleting drum and the squeeze roller can rotate in opposite directions; and the cold air blowing device blows cold air to the position which material particles falls down onto of the inner wall of the pelleting drum and blows material particles pelleted out of the pelleting drum and collects the same. The method and the device have the advantages that: the prepared thermo-setting plastic particles are uniform; dust is greatly reduced in a processing process; environment is protected and worker health is improved.
Description
Technical field
The present invention relates to a kind of plastic granulating method and device, particularly a kind of thermosetting plastics prilling process and device.
Background technology
Existing thermosetting plastics is undertaken by breaking method, and its device mainly depends on pulverizer, promptly by pulverizer thermosetting plastics is pulverized granulation.
Shortcoming by breaking method and pulverizer granulation is: the thermosetting plastics particle is inhomogeneous, and dust is many in the process, influences environment and workers ' health.
Summary of the invention
The object of the invention provides a kind of thermosetting plastics prilling process and device, and is inhomogeneous to overcome the thermosetting plastics particle that original breaking method granulation brought, and the many shortcomings of dust in the process.
For achieving the above object, the present invention is achieved through the following technical solutions: the prilling process of this thermosetting plastics is: reinforced earlier, feed in raw material expected for a kind of soft group that extrude, that have uniform temperature that handled through preceding working procedure, similar; Again by granulation cylinder outer wall extruding charging; Scrape granulating and forming at granulation inner wall of rotary drum cutter again; Wind is sent material again.Can also the defective material that the outer wall scraper will adhere on the granulation cylinder outer wall be set at the granulation cylinder outer wall in addition scrapes.
The prilling granulator of this thermosetting plastics mainly comprises charge door, compression roller, granulation cylinder, cold wind blowing device, inwall scraper, outer wall scraper etc.
At first, granulation cylinder and compression roller circumference with holes are circumscribed, and two parts can be done in opposite directions and rotatablely move; Directly over the circumscribed place of circumference, charge door is set; At the granulation inner wall of rotary drum scraper is set; In granulation cylinder one side one cold wind blowing device is set vertically, blows a cold wind over toward the granulation inner wall of rotary drum material grain place of dropping, the material grain after granulation is finished blows out the outer back of granulation cylinder and collects.
Secondly, granulation cylinder outer wall one side contacts with compression roller, and opposite side can be provided with a scraper, is used to scrape the defective material that adheres to the granulation cylinder outer wall.
Once more, the circular hole on the granulation cylinder can be made the conical bore that the granulation cylinder outer wall is little, inwall is big, what be convenient to expect extrudes.
The beneficial effect of thermosetting plastics prilling process of the present invention and device is: institute's fabricate-heat solidity plastic grain is even, and has significantly reduced the dust in the process, helps environment and workers ' health.
Description of drawings
Fig. 1 is a thermosetting plastics prilling granulator perspective view.
Fig. 2 is a thermosetting plastics prilling granulator side structure schematic diagram.
Wherein the symbol description of Fig. 1 to Fig. 2 is as follows: 1, compression roller, 11, the extrusion roll shaft core, 2, the granulation cylinder, 21, granulation drum shaft core, 3, charge door, 4, cold wind blowing device, 41, cold wind, 5, the inwall scraper, 6, the outer wall scraper, 7, circular hole, 8, the material grain.
The specific embodiment
As shown in Figure 1 and Figure 2, be the structural representation of thermosetting plastics prilling granulator.This device mainly comprises charge door 3, compression roller 1, granulation cylinder 2, cold wind blowing device 4, inwall scraper 5, outer wall scraper 6 etc.
At first, granulation cylinder 2 and compression roller 1 circumference with holes are circumscribed, and compression roller 1 and granulation cylinder 2 can be done in opposite directions and rotatablely move; Directly over the circumscribed place of circumference, charge door 3 is set; At granulation cylinder 2 inwalls an inwall scraper 5 is set; In granulation cylinder one side one cold wind blowing device 4 is set vertically, blows a cold wind over 41 toward the granulation cylinder 2 inner wall material grain places of dropping, the material grain 8 after granulation is finished blows out granulation cylinder 2 outer backs and collects.
Secondly, the opposite side that granulation cylinder 2 outer walls one side contacts with compression roller 1 can be provided with an outer wall scraper 6, is used to scrape the defective material that adheres to granulation cylinder 2 outer walls.
Once more, the circular hole on the granulation cylinder 27 can be made the conical bore that granulation cylinder 2 outer walls are little, inwall is big, what be convenient to expect extrudes.
The step of granulation is: 1, reinforced: as by charge door 3 the thermosetting plastics raw material to be delivered to compression roller 1 and the circumscribed place of granulation cylinder 2 circumference; 2, extruding charging: compression roller 1 and granulation cylinder 2 are made move toward one another, and raw material is pushed in the circular hole 7 of granulation cylinder 2; 3, cutter is scraped granulation: the material that will be squeezed into granulation cylinder 2 inwalls by inwall scraper 5 scrapes, and forms material grain 8; 4, wind is sent material: blow a cold wind over 41 by cold wind blowing device 4 in the granulation cylinder, will expect that grain 8 produces by boasting; 5, remove defective material: simultaneously, granulation cylinder 2 outer walls are provided with the defective material that outer wall scraper 6 will adhere on granulation cylinder 2 outer walls and scrape.
