Abstract

The utility model relates to a granulation machine. Mainly a vacuum reserve tank and a sealing tank body are additionally arranged on the basis of a conventional melting method dripping plate granulation machine, a machine head and a granule outlet are correspondingly improved, the whole process of granulation is isolated with oxygen in air, amino benzene assistant granules can be prevented from oxidation in the process of granulation, and the quality of assistant granules can be improved.

Description

Fusion method vacuum granulation machine

The utility model relates to a kind of comminutor, and especially fusion method drips the plate comminutor.

Along with demands of social development, people are more and more higher to the quality requirement of rubber, and the rubber chemicals granulating is to improve the key point of rubber product quality, and various types of for this reason comminutors arise at the historic moment.At present; liquid phase method is generally adopted in the auxiliary agent granulation in the world; extrusion and fusion method; with regard to fusion method, be divided into the spraying balling-up again and drip the plate granulation, the comminutor that Beijing Yanshan Petrochemical head factory uses belongs to a kind of fusion method and drips the plate comminutor; the granulation cooling procedure of this comminutor all is exposed among the atmosphere; during with the builder granule of stupid amine (as the stupid diamines of phosphorus, paraphenylenediamine, to stupid amine of chlorine etc.), very easily oxidized in production, directly have influence on the result of use of builder granule.

The purpose of this utility model is: drip the problem that the plate comminutor exists at present fusion method, a kind of fully closed vacuum granulation machine is provided.

The purpose of this utility model is to realize like this; a kind of fusion method vacuum granulation machine; form by finished product jar, head, steel band, scraper, transmission system, cooling system; it is characterized in that: set up a vacuum between finished product jar and the filter and stock jar, simultaneously head, steel band, scraper, transmission system, cooling system are placed the tank body of sealing.

Advantage of the present utility model is: since the whole process of production of granulation is adopted fully closed, isolated with the oxygen in the atmosphere, especially when producing stupid amine builder granule, avoided oxidation, improved the quality of builder granule.

Fig. 1 is that fusion method drips plate comminutor local pictures;

Fig. 2 is the utility model structural representation;

Fig. 3 is the handpiece structure schematic diagram;

Fig. 4 is a head A-A schematic cross-section;

Below in conjunction with accompanying drawing the utility model embodiment is further described.

As seen from Figure 1; traditional fusion method drips the plate comminutor to be made up of head (1), steel band (2), scraper (3), cooling system (4) and transmission system etc.; (because of the restriction of objective condition, also have finished product jar, filter can't take in photo, transmission system also can't mark).This comminutor, whole granulation process all is exposed among the air basically.

As seen from Figure 2; the utility model drips on the basis of plate comminutor at traditional fusion method; done following improvement: between finished product jar (23) and filter (6), set up a vacuum and stock jar (7); simultaneously traditional fusion method is dripped the head (1) of plate comminutor; steel band (2); scraper (3); cooling system (4) and legacy system place among the tank body (8) of a sealing; vacuum stock jar (7) and the tank body (8) that seals on be equipped with vacuum-pumping tube (9) and nitrogen blanketing valve (10); be provided with out a passage (12) in the bucket type of scraper (3) below mouthful (11) bottom that gathers materials; go out to be provided with the tumbler axle (13) that rotates synchronously with steel band in the passage, roller bearing (13) is provided with and the akin pit of finished particle (14).For guaranteeing the sealing of tank body (8), present embodiment has been established two identical roller bearings (13) in going out a passage (12).

By Fig. 3 and Fig. 4 as seen; the outer tube (15) that the head core (14) of the head after the improvement (1) and tube wall are covered with hole (wherein outer tube and traditional comminutor and indifference) is formed; combine closely with outer tube (15) bottom for guaranteeing that head core (14) is eccentric; head core (14) top V-arrangement is provided with two groups of feather keys (17) that supported by spring (16); in head core (14), be provided with at least to a heating pore (18); and a charging pore (19) and discharging pore (20) arranged; wherein, also be provided with row's blanking between charging pore (19) and the discharging pore (20) and distribute passage (21).For preventing finished product material premature solidification in head, the utility model embodiment is provided with two heating pores in head, and increases a heating tube (22) in discharging pore (20).

Transmission system described in the utility model will drive head overcoat (15), steel band (2) and roller bearing (13) synchronization action.

The utility model is when producing, earlier vacuum being stocked jar (7) and sealed shell of tank (8) vacuumizes, charge into nitrogen then, in the production process, the finished product material can be clamp-oned in the head core (14) of head (1) by an electrodynamic pump, also can when charging into nitrogen, make the pressure of sealed shell of tank (8) be lower than the pressure that vacuum is stocked jar (7), the finished product material is entered under action of pressure in the head core (14) of head (1) automatically.
