Description

Technical Field

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

[0002] Masterbatch, a new product developed in the 1960s for coloring plastics and fibers, is a polymer composite made by uniformly loading pigments in unusually high quantities into a resin. Traditional masterbatch production involves rapid cooling and finalizing the product, resulting in a high surface moisture content. Existing technologies typically separate the conveying, pre-water removal, and drying processes. Even after pre-water removal, a small amount of moisture remains in the masterbatch. Whether conveyed by gravity or screw conveying, the masterbatch is susceptible to sticking, resulting in incomplete delivery and some remaining in the conveying channel, hindering smooth delivery. Utility Model Content

[0003] The purpose of the utility model is to provide a drying device for processing plastic masterbatch, so as to solve the problem in the background art that masterbatch is cold and sticks together after pre-dehydration, resulting in incomplete transportation, partial retention in the transportation channel, and poor transportation.

[0004] The utility model provides the following technical solution: a drying device for processing plastic masterbatches, comprising: a vibrating dewatering device, a heating device, and a drying box; the vibrating dewatering device is provided with a U-shaped side panel, a screen and an inclined plate are fixedly connected to the inside of the side panel, the inclined plate is located below the screen, a vibration motor is fixedly connected to the outside of the side panel, the side panel and the supporting legs are elastically connected by a spring, a water collecting box is provided below the inclined panel, the water collecting box is fixedly connected to the side panel, and the water collecting box is fixedly connected to a drain pipe.

[0005] Preferably, the drying box is provided with a feed port, the feed port is located below the screen, an air outlet communicating with the interior is provided on the outside of the drying box, and an aggregate structure is provided inside the drying box, wherein:

[0006] A slope is provided above the aggregate structure, and a groove for accommodating spiral blades is provided inside the aggregate structure.

[0008] Preferably, the heating device is located above the drying box, and the heating device is arranged in the drying box cover and fixedly connected to the drying box cover through the heating device shell.

[0009] Preferably, the heating device casing is provided with an air inlet connecting the inside and the outside, a fan motor is fixedly connected to the top of the heating device casing, a fan is fixedly connected to the output end of the fan motor, a heating coil is provided below the fan, and the heating coil is respectively provided with an upper fixing frame and a lower fixing frame fixedly connected to the heating device casing.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The surface of the masterbatch that has just been cooled in the water pool has a large amount of water. The existing technology generally removes water by setting up a pre-dewatering device. However, the utility model adds a vibration dewatering device when the masterbatch is put into the drying box. It not only reduces a process and saves time, but also can shake the masterbatch before it enters the drying box, allowing it to be dried more evenly.

[0012] 2. The drying box is equipped with a spiral blade-adapted aggregate structure. When the masterbatch enters the drying box, it falls into the groove with the spiral blade. When the heating device is activated, the spiral blade rotates and stirs the masterbatch. The masterbatch pushed forward and accumulates at the tail. When it slides back through the slope of the aggregate structure, the masterbatch is heated more evenly during heating and drying, and the masterbatch will not stick together due to the back-and-forth stirring.

A vibration motor 11 is fixedly connected to the outside of the side panel 12. The side panel 12 and the support leg 17 are elastically connected by a spring 18. A water collecting box 15 is provided below the inclined plate 14, and the water collecting box 15 is fixedly connected to the side panel 12. The water collecting box 15 is fixedly connected to the drain pipe 16. The heating device 2 is located above the drying box 3. The heating device 2 is arranged in the cover of the drying box 3 and is fixedly connected to the cover of the drying box 3 through the heating device shell 21.

[0025] The heating device housing 21 is provided with an air inlet 27 connecting the inside and the outside. A fan motor 22 is fixedly connected to the top of the heating device housing 21, and a fan 23 is fixedly connected to the output end of the fan motor 22. A heating coil 24 is provided below the fan 23. The heating coil 24 is respectively provided with an upper fixing frame 25 and a lower fixing frame 26 fixedly connected to the heating device housing 21. The air inlet 27 ensures the continuous supply of air and enhances the heat exchange efficiency.

[0026] The drying box 3 is provided with a feed port 31, which is located below the screen 13. An air outlet 32 is provided on the outside of the drying box 3 to communicate with the inside. The heated and evaporated water vapor can be discharged through the air outlet 32. An aggregate structure 35 is provided inside the drying box 3, wherein:

[0027] A slope 356 is provided above the aggregate structure 35 , and a groove 357 for accommodating the spiral blade 36 is provided inside the aggregate structure 35 . The aggregate structure 35 can cooperate with the spiral blade 36 to allow the masterbatch to move back and forth during drying, so that it is evenly heated during drying.

[0028] A spiral blade 36 is provided inside the groove 357, and a spiral conveying motor 33 is provided at the driving end of the spiral blade 36. The spiral blade 36 can be used to stir the masterbatch during drying so that it is heated evenly. The spiral conveying motor 33 is located outside the drying box 3 and is fixedly connected to the drying box 3. A motor cover 34 is provided outside the spiral conveying motor 33 to prevent water from affecting the operation of the spiral conveying motor 33. A discharge pipe 37 is provided at the end of the spiral blade 36. The discharge pipe 37 is fixedly connected to the drying box 3. A valve 38 is provided in the discharge pipe 37 to prevent the masterbatch from leaking when the drying is not completed. When the drying is completed, the spiral blade 36 is used to convey the masterbatch to the discharge pipe 37. The slope 356 on the aggregate structure 35 can make the masterbatch accumulated on the top slide into the groove 357, and then the spiral blade 36 conveys the masterbatch.

[0029] Working principle:

[0030] The cooled masterbatch is placed into the vibrating dewatering device 1. The vibration motor 11 is activated, and the spring 18 vibrates the side plate 12, the screen 13 inside it, and the inclined plate 14. The masterbatch moves forward due to the vibration, and during this movement, the surface moisture is removed. The water flows through the screen 13 and falls to the inclined plate 14 below. It slides into the water collection tank 15 at the end of the inclined plate 14 and is discharged through the drain pipe 16. The masterbatch enters the drying box 3 through the feed port 31. The heating device 2 blows hot air to dry the masterbatch. The spiral blades 36 at the bottom rotate to stir the masterbatch. When the masterbatch is pushed to the rear end by the spiral blades 36 and accumulates, it slides forward on the slope 356 of the collecting structure 35, causing the masterbatch to move back and forth, ensuring more uniform drying. After drying is completed, the valve 38 is opened, and the spiral blade 36 pushes the masterbatch to be spirally transported to the discharge pipe 37. The masterbatch above slides to the groove 357 below through the slope 356 of the gathering structure 35, and is then pushed to the discharge pipe 37 by the spiral blade 36 to complete the drying.
