Description

Technical Field

[0001] The utility model belongs to the technical field of masterbatch drying, and particularly relates to a masterbatch drying device. Background Technique

[0002] Masterbatch is an indispensable colorant in plastic products, and its production process is strict and diverse. Common production methods include the ink method, the washing method, the kneading method, etc. In the ink method, a low-molecular protective layer is coated on the surface of the pigment through three-roll grinding, and then it is mixed with the carrier resin, and masterbatch is made through plasticization and granulation. The washing method uses sand grinding to refine the pigment particles, and transfers the pigment into the oil phase through the phase transfer method, and masterbatch is obtained after drying. The kneading method is to mix the pigment with the oily carrier, and utilize the lipophilic property of the pigment to make the pigment enter the oil phase from the water phase through kneading, and be coated by the oily carrier to ensure stable dispersion of the pigment. These methods all require strict process control to ensure that the masterbatch has bright colors, uniform dispersion, and environmental protection and safety.

[0003] Currently, during the production of masterbatch materials, after the long-strip masterbatch raw materials come out, they need to be cooled. After the long-strip masterbatch is cooled by a water-cooling tank, a large amount of water stains will remain on the masterbatch strip. Therefore, after cooling, these water stains often need to be treated to facilitate the next processing of the long-strip masterbatch. Existing masterbatch drying equipment on the market, such as double-cone rotary vacuum dryers, drum dryers, etc., can dry the masterbatch after granulation, but cannot directly dry the uncut long-strip masterbatch after cooling. Therefore, there is an urgent need to design a drying device for long-strip masterbatch after cooling during production. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Refer to Figures 1 to 4, a masterbatch drying device according to this embodiment includes a bottom plate 1. An eddy current fan 4 is fixedly installed at the upper end of the bottom plate 1.

An air suction pipe 13 is fixedly installed on the front surface of the first housing 16. An air suction hole 12 is opened at the upper end of the air suction pipe 13. The output end of the eddy current fan 4 is fixedly connected with an air outlet pipe 7. The other end of the air outlet pipe 7 is fixedly installed with the back surface of the second housing 17. A hot air pipe 10 is fixedly installed on the front surface of the second housing 17. A hot air hole 11 is opened at the upper end of the hot air pipe 10. Adjusting mechanisms 18 are opened on the outer sides of both the first housing 16 and the second housing 17. An installation rod 15 is arranged on the outer side of the adjusting mechanism 18. A material conveying roller shaft 14 is arranged on the outer side of the installation rod 15. Material conveying roller grooves are also equidistantly arranged on the material conveying roller shaft 14, which can prevent long strip masterbatch from slipping off the material conveying roller shaft 14. A filtering and separating device is also arranged inside the first housing 16. When the airflow with water stains passes through the filter material in the first housing 16, small liquid droplets in the gas can be captured and gradually form large liquid droplets, and finally converge and discharge under the action of gravity, achieving the separation purpose of the gas and the small liquid droplets. The small water droplets converge under the action of gravity and are collected through the water box at the bottom of the first housing 16. The filter material specifically adopts substances with hydrophobic, oleophobic, low surface energy, corrosion resistance, and certain mechanical strength, such as fluorosilicone glass fiber cotton, etc. These materials can effectively capture small liquid droplets in the gas. In addition, a water receiving plate is installed between the top of the assembly rod on the front side of the bottom plate 1 and the support rod 2, which can prevent water stains from falling onto the eddy current fan 4. After the long strip masterbatch is cooled, it is placed on the material conveying roller shaft 14 and moves slowly. At the same time, the input end of the eddy current fan 4 is connected to the first housing 16 with the air suction pipe 13 through the air inlet pipe 8. By using the air suction hole 12 on the air suction pipe 13, under the negative pressure action of the eddy current fan 4, the water stains outside the masterbatch can be absorbed. The water stains will be separated from the water stains and the air through the filtering and separating structure in the first housing 16, and the water stains will be centrally collected. After the air enters the input end of the eddy current fan 4, since the eddy current fan 4 itself is also in a negative pressure state all the time, mechanical heat will be generated inside the eddy current fan 4. The heat can be transported into the hot air pipe 10 at the second housing 17 through the air outlet pipe 7 output by the eddy current fan 4 and discharged through the hot air hole 11 on the hot air pipe 10, which can further dry the long strip masterbatch, so as to facilitate the cooling and drying after the long strip masterbatch raw material comes out;

The threaded end of the adjusting bolt 183 penetrates through the adjusting hole 182. The mounting rod 15 is fixedly installed at one end of the connecting plate 181 away from the supporting plate 184. By tightening the adjusting bolt 183 on the supporting plate 184, the connecting plate 181 can be clamped and fixed. By using the adjusting bolt 183 threadedly connected to the supporting plate 184 in cooperation with the adjusting hole 182 on the connecting plate 181, the position of the material feeding roller shaft 14 on the mounting rod 15 at the connecting plate 181 can be conveniently adjusted for use.

[0024] Reference Figure 2 , a threaded hole 19 is formed in the inner side of the supporting plate 184. The threaded end of the adjusting bolt 183 and the threaded hole 19 are in threaded connection. By using the threaded end of the adjusting bolt 183 to penetrate through the threaded hole 19 on the supporting plate 184, the supporting plate 184 and the adjusting bolt 183 can conveniently clamp and fix the connecting plate 181.

[0025] Reference Figure 1 , fixing plates 5 are symmetrically and fixedly connected to the lower end of the eddy current blower 4. Fixing holes 6 are formed in the inner sides of the fixing plates 5.

By using the air suction holes 12 equally spacedly arranged on the arc surface at the upper end of the air suction pipe 13, the water stains on the long strip color masterbatch can be conveniently absorbed. At the same time, the hot air holes 11 on the hot air pipe 10 can conveniently perform further drying treatment on the long strip color masterbatch particles.

[0028] Principle of use and advantages: During use, first, after the long strip masterbatch is cooled, it is placed on the material feeding roller shaft 14 and moves slowly. At the same time, the input end of the eddy current fan 4 is connected to the first housing 16 with an air suction pipe 13 through an air inlet pipe 8. By using the air suction holes 12 on the air suction pipe 13, under the negative pressure of the eddy current fan 4, the water stains on the outside of the masterbatch can be absorbed. The water stains will be separated from the water stains and air through the filtration and separation structure in the first housing 16, and the water stains will be collected centrally. After the air enters the input end of the eddy current fan 4, since the body of the eddy current fan 4 itself is always in a negative pressure state, mechanical heat will be generated inside the eddy current fan 4. The heat can be transported into the hot air pipe 10 at the second housing 17 through the air outlet pipe 7 output by the eddy current fan 4 and discharged through the hot air holes 11 on the hot air pipe 10, which can further dry the long strip masterbatch, so as to facilitate the cooling and drying of the long strip masterbatch raw material after it comes out;

[0029] During the use process, the connecting plate 181 can be clamped and fixed by tightening the adjusting bolt 183 on the support plate 184. By using the adjusting bolt 183 threadedly connected to the support plate 184 and cooperating with the adjusting hole 182 on the connecting plate 181, the position of the material feeding roller shaft 14 on the mounting rod 15 at the connecting plate 181 can be conveniently adjusted for use.
