TECHNICAL FIELD

[0001] The utility model relates to a water cooling device for plastic master batch production belongs to the plastic master batch production field. BACKGROUND

[0002] At present, the plastic master batch preparation is generally through the production process of double screw extrusion granulation. In this process, various raw materials are mixed in a certain proportion after passing through the mixing device, and then are heated into melt by the double screw, the melt enters the die after passing through a simple filtering device, becomes a thin strip and is extruded, then is water cooled in the water tank, and then enters the pelletizing device and is cut into plastic particles. The plastic strip after extrusion is generally water cooled in the water tank.

[0003] With the cooling, the temperature of the water in the water tank is continuously increased, and when the temperature is increased to a certain temperature, it can no longer effectively cool the plastic strip, so new cooling water needs to be added to reduce the temperature of the water tank and ensure the cooling effect.

[0004] The disadvantages are:

[0005] The existing water tank cooling method is relatively simple, which is only a simple water tank, and the cooling effect can meet the actual production, but the water in the water tank has a small contact area with air, the heat dissipation effect is poor, the temperature rises quickly, and the water in the water tank needs to be continuously supplemented with new cooling water, and the amount of cooling water to be supplemented is large. UTILITY MODEL CONTENTS

[0006] The utility model discloses to the huge shortcoming that the existing water tank cooling device needs to be continuously supplemented with new water and a large amount of water is used, the cooling water supplement is greatly reduced by improving the existing cooling device, the amount of cooling water is effectively reduced, and therefore the production cost is reduced.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A water cooling device for plastic master batch production, comprising a water tank, a plurality of hollow heat dissipation pipes are arranged on the two sides of the water tank, the two ends of the heat dissipation pipes are communicated with the water tank, a ventilation cover with an upper opening and a lower opening is arranged outside the heat dissipation pipes, the ventilation cover forms an air duct, the air duct is perpendicular to the ground, the two ends of the ventilation cover are fixedly connected to the outer wall of the water tank, and the side wall of the heat dissipation pipe is provided with a heat dissipation fin.

[0009] Further, the air duct is a rectangular air duct.

[0010] Further, the heat dissipation pipes are arranged on a plane, and the plane is perpendicular to the ground.

[0011] Further, the heat dissipation pipes are U-shaped pipes.

[0012] Further, the heat dissipation pipe is a copper pipe, and the heat dissipation fin is made of aluminum.

[0013] Further, the water tank is a rectangular water tank.

[0014] In general, the present application has the following advantages:

[0015] Compared with the prior art, the present application can greatly reduce the amount of cooling water to be supplemented or even realize no supplement of cooling water under the premise of ensuring the cooling effect of the plastic strip.

[0016] This is because the present application is provided with heat dissipation pipes with fins on two side walls of the water tank, which effectively increases the cooling area of the water, and the chimney effect formed by the cooling air duct improves the air convection, thereby improving the cooling effect of the water tank, so that the water in the water tank is heated slowly, the amount of water to be supplemented is small, and the use amount of water in the production process is effectively reduced.
