Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a drying device for masterbatch processing. Background Art

[0002] Masterbatch is a coloring material used in plastic processing. It is a concentrate made from pigments or dyes and carrier resins through a special process. The main function of masterbatch is to provide color in the production process of plastic products.

[0003] Through searching, it was found that CN221021877U discloses a drying device for masterbatch processing. The masterbatch after phase transfer and water washing is poured along the notch of the feeding frame. To ensure that the masterbatch can accurately fall onto the surface of the lower collecting frame, after the loading is completed, the hydraulic cylinder on the top of the upper support frame can be automatically started, and its piston end pushes the push rod, and the push rod pushes the limit frame, so that the bottom of the limit frame is stuck into the slot of the lower collecting frame, thereby completing the sealing between the limit seat and the lower collecting frame, and preventing the masterbatch from shaking out of the lower collecting frame during the water-spinning drying process; the stepper motor outside the drying box can be started, and its motor shaft drives the drive shaft to rotate, and the drive shaft drives the positioning frame to rotate, so that the masterbatch in the limit frame and the lower collecting frame can complete the comprehensive drying effect under the action of the dryer; and during the rotation process, the moisture left on its surface after water washing is thrown out from the outside of the filter screen under the action of Li Xinli, thereby accelerating the drying rate.

Only after the masterbatches in the current collecting rack are dried can the next batch of masterbatches be dried. Continuous drying work cannot be performed, and the drying efficiency is low. Therefore, we need an efficient drying device for masterbatch processing. Utility Model Content

And a plurality of water vapor suction mechanisms 9 are equidistantly arranged on the outer surface of the spiral drying tube 2.

[0025] By putting the masterbatch into the feed hopper 4 and then turning on the hot air blower 8, under the action of gravity and the blowing of the hot air blower 8, the masterbatch can spiral down along the inner wall of the spiral drying tube 2. The hot air generated by the hot air blower 8 will enter the spiral drying tube 2 after being filtered by the water vapor filtering component 6, so as to air-dry the masterbatch. Using the support heating column 3 can not only slow down the moving speed of the masterbatch in the spiral drying tube 2 to increase the drying time, but also improve the drying effect of the masterbatch. Using the water vapor suction mechanism 9 can discharge the water vapor in the spiral drying tube 2. Finally, the dried masterbatch will be discharged from the discharge pipe 5. The utility model can continuously carry out the masterbatch drying work, greatly improving the masterbatch drying efficiency.

[0026] The water vapor filtering component 6 includes a first arc plate 10, a second arc plate 11 and a water vapor filter net 12. One end of the first arc plate 10 is fixedly connected to the end of the spiral drying tube 2, and the other end of the first arc plate 10 is fixedly connected to the outer surface of the air duct 7. The second arc plate 11 is hinged to the end of the first arc plate 10. And fixing bolts 13 are commonly threadedly connected to the surfaces of the first arc plate 10 and the second arc plate 11. Card slots are opened on the inner sides of the first arc plate 10 and the second arc plate 11. The water vapor filter net 12 is clamped and fixed in the card slots. By setting the water vapor filter net 12, it can effectively prevent the outside water vapor from entering the spiral feeding tube. By setting the fixing bolts 13, the first arc plate 10, the second arc plate 11 and the water vapor filter net 12, by removing the fixing bolts 13 and then rotating the second arc plate 11, it is convenient to disassemble and replace the water vapor filter net 12.

[0027] The water vapor suction mechanism 9 includes a suction fan 14, an exhaust pipe 15, and a baffle 16. The exhaust pipe 15 is fixedly connected to the outer surface of the spiral drying pipe 2. The suction fan 14 is fixedly installed at one end of the exhaust pipe 15 away from the spiral drying pipe 2. The baffle 16 is fixedly connected to the inner wall of the exhaust pipe 15, and a plurality of through holes 17 are formed on the surface of the baffle 16. The diameter of the through holes 17 is smaller than the diameter of the masterbatch. By operating the suction fan 14, the water vapor in the spiral drying pipe 2 can be discharged from the exhaust pipe 15, and the baffle 16 can effectively prevent the masterbatch from entering the exhaust pipe 15.

[0028] The center position of the surface of the support frame 1 is fixedly connected with a storage barrel 18. A feeding port 19 is formed on the upper surface of the storage barrel 18. The surface of the storage barrel 18 is also rotatably connected with a cover 20 for blocking the feeding port 19 in a damping manner. A discharge pipe 21 is arranged on the lower surface of the storage barrel 18, and a solenoid valve 22 is arranged on the discharge pipe 21.

[0030] By providing the storage barrel 18, it is convenient to store and preserve the dried masterbatch. And in cooperation with the heat emitted by the plurality of support heating columns 3, and by using the heat preservation enclosure 23, the heat dissipation can be effectively avoided, so that the storage barrel 18 can be heated, and then the masterbatch stored in the storage barrel 18 can be kept dry for a long time. By opening the solenoid valve 22, the masterbatch in the storage barrel 18 can be discharged from the discharge pipe 21, which facilitates the use of the masterbatch at any time and provides convenience for the user.

[0031] Working principle: When the drying device for masterbatch is in use, first, the electric heating tubes, the hot air blower 8, and the suction fan 14 in the support heating column 3 can be turned on. After the spiral drying pipe 2 is preheated, the masterbatch to be dried is put into the feed hopper 4. At this time, the masterbatch will fall into the spiral drying pipe 2. By operating the hot air blower 8, the hot air can be filtered by the water vapor filtering component 6 and then conveyed into the spiral drying pipe 2 through the air duct 7. Under the action of gravity and the blowing of the hot air blower 8, the masterbatch can spiral down along the inner wall of the spiral drying pipe 2. When the masterbatch rolls and touches the support heating column 3, its moving speed will be reduced, so that the masterbatch can be air-dried. The support heating column 3 can not only slow down the moving speed of the masterbatch in the spiral drying pipe 2, but also improve the drying effect of the masterbatch. By operating the suction fan 14, the water vapor in the spiral drying pipe 2 can be discharged. Finally, the dried masterbatch will be discharged from the discharge pipe 5. The utility model can continuously carry out the masterbatch drying work, greatly improving the masterbatch drying efficiency.
