Description

Technical Field

[0001] The utility model belongs to the technical field of masterbatch drying devices, and particularly relates to a high-efficiency carrier-free dehydration and drying device for masterbatch granulation. Background Art

[0002] Currently, the most commonly used coloring method for plastic or rubber products is masterbatch coloring. Masterbatch not only offers advantages such as ease of use, accurate color matching, and uniform pigment dispersion, but also effectively addresses some of the problems existing in traditional plastic coloring methods. Masterbatch is a composite material specifically designed for coloring polymer materials. It is typically composed of a colorant, a carrier resin, a dispersant, and other functional additives. Through a special process, an excessive amount of colorant is evenly distributed in the carrier resin to produce a pigment concentrate. This pigment concentrate can then be mixed with a base resin in a proportional manner and molded into a colored plastic or rubber product. Granulation is a critical step in the masterbatch production process, directly affecting the final product quality. During granulation, the masterbatch needs to be dried.

[0003] Chinese patent application number 2016206628540 discloses a masterbatch drying device, comprising an upper drying pot and a lower drying pot, wherein a feed pipe is provided on the upper side wall of the upper drying pot, a drying plate is provided in the upper drying pot, the drying plate is provided with a plurality of evenly distributed feed holes, and an electric heating wire is provided in the drying plate; the upper drying pot is provided with an air vent I and an air inlet pipe I, the upper end of the air inlet pipe I is connected to a blower I; the air inlet pipe I is provided with a heating box, and the heating box is provided with an electric heating wire; a flow sensor is provided at the discharge port I at the lower end of the upper drying pot; a solenoid valve is provided at the feed port II of the lower drying pot; a stirring device is provided in the lower drying pot, and the rotating shaft of the stirring device is connected to the motor through a coupling; the lower end of the lower drying pot is connected to the blower II through the air inlet pipe II, and an exhaust hole II is provided at the upper end of the lower drying pot.

[0004] The above solution has the effect of uniform drying, but the above drying process is completely carried out in the drying pot, the masterbatch is easy to pile up together, and some masterbatch cannot fully contact with the hot air, resulting in drying blind spots. Utility Model Content

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. When an element is referred to as being "fixedly connected to" another element, it can be a common fixed connection method such as welding, bolt connection, or gluing connection. In short, for ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] Example 1, as Figure 1 -shown, a high-efficiency dehydration and drying device for carrier-free masterbatch granulation, including a base 1, a drive base 2 and a plurality of support plates 3 are provided above the base 1, a first drive motor 4 is installed on the drive base 2, a dehydration conveying pipe 5 is installed on the support plate 3, a plurality of dehydration holes 6 are provided on the surface of the dehydration conveying pipe 5, a first feeding screw 7 is provided inside the dehydration conveying pipe 5, the first drive motor 4 drives the first feeding screw 7 to rotate, the first feeding screw 7 is provided with a feeding port at one end close to the first drive motor 4, a feeding kettle 8 is provided above the first feeding screw 7, a drying mechanism is provided at the other end of the first feeding screw 7, the drying mechanism includes a drying conveying seat 9, a second feeding screw 10 is provided inside the drying conveying seat 9, a second drive motor 11 is provided at the end of the drying conveying seat 9, the drive motor drives the second feeding screw 10 to rotate, a blower 12 is provided at the bottom of the drying conveying seat 9, the air outlet end of the blower 12 is connected to the bottom of the drying conveying seat 9, a cover 13 is provided above the drying conveying seat 9, and an air outlet pipe 14 is provided above the cover 13.

[0024] The conveyor kettle conveys the masterbatch material to the dehydration conveyor pipe 5. The first drive motor 4 rotates the first feed screw 7, causing the masterbatch material to slowly pass through the dehydration conveyor pipe 5, where it continuously comes into contact with air. Water drips from the dehydration conveyor pipe 5 and then enters the drying conveyor seat 9. The second feed screw 10 delivers the material to the designated location. During the conveyance process at the drying conveyor seat 9, the blower 12 creates airflow, which vibrates the masterbatch and removes moisture from the outlet pipe 14. The slow conveyance of the first feed screw 7 ensures that the masterbatch material is fully exposed to air in the dehydration conveyor pipe 5, effectively removing surface and internal moisture and avoiding uneven drying caused by accumulation. Subsequently, in the drying conveyor seat 9, the masterbatch material is subjected to the airflow from the blower 12 while being spirally conveyed, further promoting the evaporation and removal of moisture, thereby improving overall drying efficiency. Because the masterbatch material continuously vibrates and comes into contact with the airflow during conveyance, blind spots in the drying process are effectively reduced, ensuring that every masterbatch is fully dried. The dual effects of spiral conveying and airflow blowing ensure that the masterbatch can be evenly exposed to hot air during the conveying process, avoiding the drying blind spot problem caused by accumulation in traditional methods, and making the drying effect more uniform and consistent.

[0025] There are two dehydration conveying pipes 5 and two first feed screws 7. A gear box 15 is provided on the drive base 2. The ends of the two first feed screws 7 extend to the gear box 15 and are rotatably connected to the side walls of the gear box 15. The ends of the two first feed screws 7 are connected to driven gears 16. The output end of the first drive motor 4 extends into the gear box 15 and is connected to a driving gear 17. The driving gear 17 meshes with the two driven gears 16. When the first motor rotates, it can simultaneously drive the two first feed screws 7 to rotate. The simultaneous operation of the two dehydration conveying pipes 5 and the first feed screws 7 enables the dehydration process of the masterbatch material to be carried out in parallel, greatly improving the production efficiency of the entire drying device. At the same time, since the two screws can share a drive source, this design is more cost-effective than two independently driven screws.

[0026] A heating plate 18 is mounted on the support plate 3. A heating resistor is located within the heating plate 18, which is positioned below the dehydration pipe 5. The heating resistor rapidly converts electrical energy into thermal energy, raising the surface temperature of the heating plate 18. This direct heating method quickly and effectively heats the masterbatch material in the dehydration pipe 5 above it, accelerating moisture evaporation and improving dehydration efficiency.

[0027] A stirring rod 19 is installed in the middle of the feed kettle 8, with stirring plates 20 installed on the sides. A third drive motor 21 is installed on the outside of the feed kettle 8, which drives the stirring rod 19 to rotate. The rotation of the stirring rod 19 and stirring plate 20 effectively stirs and mixes the masterbatch material in the feed kettle 8, evenly distributing the various components, avoiding stratification or sedimentation of the material during transportation, and ensuring the consistency of the material in subsequent process steps. The stirring action of the stirring rod 19 can reduce the accumulation and blockage of the material inside the feed kettle 8, allowing the material to flow and be transported more smoothly, improving the continuity and stability of the entire production process. The stirring rod 19 has a hollow structure, with an air outlet 22 at the bottom and an air supply pipe 23 at the top. The air outlet 22 and air supply pipe 23 are both connected to the hollow structure. The design of the stirring rod 19, combined with the air outlet 22 at the bottom, allows gas to be introduced into the stirring rod 19 through the air supply pipe 23. When gas is ejected from the air outlet 22 at the bottom of the stirring rod 19, it forms bubbles or airflow, which has an additional stirring effect on the material. The gas ejected from the bottom of the stirring rod 19 not only enhances the stirring effect, but also effectively reduces the adhesion between material particles, improving the material's fluidity. This is particularly important for materials that are prone to agglomeration or have high viscosity, helping to ensure smooth entry of the material into the dehydration conveying pipe 5 and reduce the risk of blockage.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
