the screw rod has set gradually from a left side to the right side and has deepened and increased feeding section, transport section, preceding backward flow district, back backward flow district, ejection of compact transport district, and has spouted the alloy face on preceding backward flow district and the back backward flow district.

Preferably, the screw adopts 38CrMoALA nitriding steel as a base material.

Preferably, the cooling water jacket is made of plastic composite materials.

The utility model provides a novel high-effect granulation barrel screw rod possesses following beneficial effect: this novel high-effect granulator barrel screw rod takes reasonable feeding section, cuts mixing section, and the material can be eliminated at the inside operation of screw rod in the plastify section and the circumstances barrel antiskid slot that the solid stopper is not appearing, and high performance water jacket device makes the user overheated messenger's material production stagnant flow state in production, is difficult for producing poison gas, and high temperature, high shear, high current, start time are long. Therefore, the screw can form films with various complicated specifications under the action of the pressure of the die.

Detailed Description

According to the first aspect of the utility model, the utility model provides a novel high-performance granulator barrel screw,

as shown in fig. 1-4, the device comprises a machine barrel 1 and a screw 8, wherein a cooling water jacket 2 is sleeved at the leftmost end of the machine barrel 1, the machine barrel 1 is sequentially provided with a transition section 3, an external circulation cleaning section 4 and an exhaust section 5 by taking the cooling water jacket 2 as a starting point, the transition section 3 is positioned at the right end of the cooling water jacket 2, the external circulation cleaning section 4 and the exhaust section 5 are positioned at the right end of the transition section 3, and the external circulation cleaning section 4 is provided with a clinker guide hole 6 and a cleaning material return hole 7;

the screw 8 is provided with a deepened enlarged feeding section 9, a conveying section 10, a front reflux area 11, a rear reflux area 12 and a discharging conveying area 13 from left to right in sequence, and alloy surfaces 14 are sprayed on the front reflux area 11 and the rear reflux area 12.

The screw 8 adopts 38CrMoALA nitriding steel as a base material.

The cooling water jacket 2 is made of plastic composite material.

It should be noted that, the screw 8 feeding is changed into the increased lead feeding, the multi-head discharging and the plasticizing mixing head, the gas and pressure reduction design leads the material to reduce the solid plug in the screw, thus shortening the retention time of the material in the machine barrel and reducing the feeding of polyethylene, calcium powder and various molecular materials to be more stable and uniform; the decomposition is not easy to generate, and the stable structure of the material tissue is ensured, so that the material conveying is obviously accelerated;

the screw 8 adopts 38CrMoALA nitriding steel as a base material, and the tungsten-containing alloy with the hardness reaching HV62 is spray-welded on the surface, so that the service life is prolonged by 2-3 times.

The material is loose gesture before getting into barrel 1 and still can skid sometimes, 8 rotatory in-process materials of screw rod and barrel wall friction make it move forward, barrel 1 adopts increase feeding storehouse, and place the clutch blocks and solved the material not good under, the condition of skidding makes the high-speed operation of screw rod become reality, because the temperature that barrel screw rod and material friction produced can make partly material melt in advance, thereby mutual adhesion makes the material grow influence the feed speed, I department designs the high performance water jacket, can make the feeding section temperature controllable, solution feeding temperature that just is fine risees at an excessive speed.

Aiming at the problem that some materials are poor in plasticizing effect, a decompression section is designed behind a screw plasticizing area, so that water vapor generated by the materials can be fully discharged, and the smoothness and the handfeel of a product are guaranteed;

the product can increase the rotation speed of the screw by 2-3 times, improve the generating efficiency by more than 150 percent, and improve the direct production benefit by 80 percent.

The utility model discloses the purpose of research and development just lies in overcoming the above-mentioned shortcoming that prior art exists and not enough, and provides the screw rod that is up-to-date practical, energy-conserving, environmental protection high efficiency. Avoid in the use: thermal decomposition is generated, toxic gas is discharged, the product quality can be ensured, energy is saved, the purpose of high-efficiency extrusion is achieved, and the advantages are provided for customers to create competition at home and abroad. And waste and defective products are reduced, and the benefit of customers is maximized.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
