Where is the invention of the masterbatch dewatering machine?

2019-07-10

The object of the present invention is to provide a color masterbatch with better drying effect and high energy efficiency in view of the lack of the prior art. Granule dewatering machine.

In order to accomplish the above object, a masterbatch dewatering machine of the present invention comprises a can body having a circular cross-sectional profile, the inside of the can body being provided with an inner tube body, the can body The two ends are disposed on the outer surface of the inner tube body, the tube wall of the inner tube body is provided with a curved filter groove, the filter groove comprises a top slot edge and a second slot edge, and the top slot edge is disposed in the second a side of the groove side, the filter groove has at least one groove edge protruding upward, a gap between the top groove edge and the second groove edge, and a lower end portion of the can body is provided for attaching to the masterbatch The outlet of the water on the outside.

Preferably, the filter tank is provided with a plurality of filter grooves arranged in a circle shape along the circumferential direction of the inner tube body. Preferably, the plurality of filter tanks are provided with at least two turns, and the filter tanks adjacent to the two turns are arranged in an interlaced manner.

Preferably, a hollow separation structure is arranged between the tank body and the inner tube body, and an upper water inlet is provided at an upper end portion of the tank body.

Preferably, the can body and the inner tube body are fixed by welding.

Preferably, the can body and the inner tube body are made of stainless steel material.

The beneficial effects of the invention: a masterbatch dewatering machine of the invention, the length of the masterbatch dewatering machine can be set to be between 3m and 5m according to the actual work demand, and the masterbatch dewatering machine Place it in an inclined manner so that the water outlet at the lower end of the tank faces downward. The tubular dehydrator is composed of a tank body and an inner tube body. The inner wall of the inner tube body is provided with a plurality of arc-shaped filter grooves laterally, and the groove side of the filter tank is different in height, which is preferred, the top slot edge and the second The scale value of the height difference of the groove sides is set between 0.05 mm and 0.2 mm. The extension line of the top slot edge forms an angle with the extension line of the second slot edge. Preferably, the angle of the included angle is set between 5° and 10°.

The primary molded masterbatch has a high surface temperature and needs to be immersed in water for cooling. The water-incorporated colored masterbatch enters the tubular dehydrator, and the blower mounted on the outside of the tubular dehydrator drives the masterbatch and The mixture of water moves forward against the wall of the inner tube body, and when passing through the filter groove laterally disposed on the inner tube body wall, the mixture moves forward along the upwardly convex groove edge to prevent color The collision of the masterbatch on the edge of the groove, and the upwardly convex groove edge are directed to the middle of the inner pipe body, so that the moving masterbatch is concentrated along the upwardly convex groove edge to the middle of the inner pipe body. Preventing the masterbatch from staying on the wall of the inner tube also helps to disperse the mass of the masterbatch which is agglomerated into a mass, and to improve the moving rate of the masterbatch. At the same time, the water in the discrete flow state flows out of the inner tube body through the passage between the top slot edge and the second slot edge.

Because the size of the channel is planned to be finer than the size of the masterbatch, it can not only quickly dehydrate but also prevent the masterbatch from being blocked in the channel. The filter tanks are uniformly arranged at a distance from the wall of the inner tube body. When the mixture flows through each of the filter tanks, water in the mixture continuously flows out from the passage of each of the filter tanks, thereby improving the power of dehydration of the masterbatch. The two ends of the can are sealed on the outside of the inner tube to provide an environment with excellent air tightness, which guarantees the durable driving force for the movement of the mixture. In the process of the aggregation of the masterbatch, the masterbatch can better remove the moisture on the outer surface of the masterbatch by rubbing against each other, because the masterbatch dewatering machine is placed obliquely, and the water is concentrated into a water flow by the effect of gravity through the lower end of the tank. The outlet of the ministry is quickly discharged.
