Abstract

The utility model discloses a pelletizing device of thermosetting plastic. The pelletizing device comprises a feeding hole, a squeeze roller, a pelletizing drum, a cold air blowing device, an inner wall scraper, an outer wall scraper and the like, wherein the pelletizing drum is externally tangent to the circumference of the squeeze roller; the pelletizing drum and the squeeze roller can rotate towards each other; and the cold air blowing device blows cold air to a position where particles on the inner wall of the pelletizing drum fall so as to blow pelletized particles out of the pelletizing drum for collecting. The pelletizing device has the advantages that: particles of thermosetting plastic are uniform, dust in the processing process is reduced greatly, and the environment and workers' health are protected.

Description

A kind of prilling granulator of thermosetting plastics

Technical field

The utility model relates to a kind of plastic granulating device, particularly a kind of thermosetting plastics prilling granulator.

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 the pulverizer granulation is: the thermosetting plastics particle is inhomogeneous, and dust is many in the process, influences environment and workers ' health.

The utility model content

The utility model purpose provides a kind of thermosetting plastics prilling granulator, and is inhomogeneous to overcome the thermosetting plastics particle that original pulverizing granulation brought, and the many shortcomings of dust in the process.

For achieving the above object, the utility model is achieved through the following technical solutions:

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.It is that a kind of soft group that extrude, that have uniform temperature that handled through preceding working procedure, similar expects that charge door feeds in raw material.

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 granulator described in the utility model 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.
