Description

Technical Field

[0001] This utility model relates to the field of color masterbatch processing technology, and more specifically, to a dehydration device for color masterbatch plastic granulation. Background Technology

[0002] Masterbatch, also known as color masterbatch or color seed, is a new type of special coloring agent for polymer materials, also called pigment preparation. Masterbatch is composed of three basic elements: pigment or dye, carrier, and additives. It is an aggregate made by uniformly loading an extraordinary amount of pigment into resin. During the plastic granulation process of masterbatch, water removal is required.

[0003] A search revealed that utility model patent CN220052468U discloses a dewatering device for color masterbatch plastic granulation, including a dewatering tank. The lower part of the dewatering tank is equipped with a stirring mechanism, the upper part with a guiding mechanism, and the right side with a heating mechanism. The guiding mechanism includes a base and a filter screen. An outer frame is fixedly installed on the outside of the filter screen, and the base is rotatably connected to the inner left side wall of the dewatering tank. This dewatering device for color masterbatch plastic granulation, through the guiding mechanism, pours color masterbatch from the feed hopper into the filter screen inside the dewatering tank. Under the weight of the color masterbatch, a T-shaped slider slides on a sliding rod, compressing a spring to extend and retract, causing the filter screen to vibrate up and down. This allows water in the color masterbatch to flow into a water tank and be discharged through an outlet hose. An electric push rod then rotates the base, causing the baffle to tilt and pour the color masterbatch off the filter screen, thus preventing the color masterbatch from sticking to the filter screen and hindering normal material flow. However, the above-mentioned patents still have the following shortcomings: it is not convenient to continuously remove water from masterbatch. At the same time, when the masterbatch falls to the bottom of the dewatering tank, the masterbatch will accumulate. Although the stirring rod can agitate it, it will affect the dewatering efficiency of the masterbatch. Therefore, we propose a dewatering device for masterbatch plastic granulation.

[0040] In this embodiment, the inner wall of the water tank 1 and the inner side of the support frame 2 are used to limit the side of the conveyor mesh belt 4 to ensure that the masterbatch conveyed on the conveyor mesh belt 4 will not fall off.

[0041] Working principle: In use, first, the color masterbatch to be dehydrated is placed into the inner cavity of the storage hopper 15. The second motor 18 is started, driving the third rotating rod 16 and rotating plate 17 to rotate, causing the color masterbatch in the inner cavity of the storage hopper 15 to enter between the two rotating plates 17. The color masterbatch then falls onto the conveyor belt 4 as the two rotating plates rotate. Simultaneously, the vibration motor 19 is started, causing the storage hopper 15 to rotate, allowing the color masterbatch to smoothly enter between the two rotating plates 17. Then, the first motor 5 is started, driving a drive roller 3 to rotate clockwise. The drive roller 3 drives the conveyor belt 4 to rotate clockwise, thus moving the color masterbatch that has fallen onto the conveyor belt 4. Additionally, the third motor 10 is started, driving the first rotating rod 8 and the first push rod 9 to rotate. The first push rod 9 pushes the conveyor belt 4 above the water receiving tank 6 to vibrate up and down, allowing water from the color masterbatch on the top surface of the conveyor belt 4 to pass through the conveyor belt. The water falls through the holes in the mesh belt 4 into the water tank 6, causing the water in the water tank 6 to be discharged through the drain pipe 7. Then, when the conveying mesh belt 4 moves the masterbatch to the inner cavity of the dewatering tank 1, the electric heating tube 21 is energized to generate heat. The blower 22 blows air downwards, and the electric heating tube 21 heats the air. The hot air dries and removes water from the masterbatch on the conveying mesh belt 4. At the same time, multiple fourth motors 28 are started to drive the second rotating rod 26 and the second push rod 27 to rotate. The second push rod 27 pushes the conveying mesh belt 4 to vibrate up and down, so as to turn the masterbatch on the conveying mesh belt 4 and ensure the quality of dewatering the masterbatch. In addition, the dewatered masterbatch falls from the end of the conveying mesh belt 4. Finally, the exhaust pump 24 is started to extract steam from the inner cavity of the exhaust hood 23. The suction force of the inner cavity of the exhaust hood 23 is used to remove the water vapor from the inner cavity of the dewatering tank 1, so that the water vapor generated during dewatering is pumped to the outside.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
