Description

TECHNICAL FIELD

[0001] The application relates to the technical field of drying devices, in particular to a drying device for color master batch production. BACKGROUND

[0003] In the production process of color master batch, the processed color master batch needs to be dried to eliminate the moisture and volatile substances in the raw materials, so as to ensure the processing stability of the color master batch and the performance of the final product. In the industry, a drying device is usually used to dry the color master batch. For example, the Chinese utility model patent with the publication number CN220719959U discloses a drying device for color master batch production. By changing the vertical rotation mode of the roller shaft in the drying process of the color master batch, the roller shaft is placed horizontally, so that the material can be fully mixed and dried in the process of roller rotation, and the color master batch at the lower part is not over-dried and the color master batch at the upper end is not under-dried.

[0004] However, in the implementation process of the above technical solution, the color master batch is dried under the drying effect of the heat dissipation block. When a large amount of color master batch is dried, long-time high-power drying is required, which will cause a large amount of energy loss in the process, affecting the drying effect and increasing the drying cost.

DETAILED DESCRIPTION

[0031] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0032] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings accompanying the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0033] As Figure 1As shown, this application provides a drying device for color masterbatch production. The device is used to dry the color masterbatch during the production process. The device includes a drying component 1, which provides a heat source for drying. The drying component 1 includes a base 11, on which a motor 12 is mounted. The output end of the motor 12 is connected to a fan 13 via a belt drive mechanism. The fan 13 operates under the drive of the motor 12. A heating box 14 is mounted on one side of the fan 13. The heating box 14 is used to heat air and is connected to the fan 13 via the motor 12 to blow the heated air to a designated location, thereby realizing the drying operation.

[0034] The outlet of the blower 13 is equipped with a connecting hose 15, which is connected to a heat chamber 16. Hot air blown out by the blower 13 is transferred to the heat chamber 16 through the connecting hose 15, thereby raising the temperature of the heat chamber 16. Simultaneously, the heat chamber 16 is connected to a mounting assembly 2, such as... Figure 1 As shown, the placement component 2 includes a support frame 21, on which a drying chamber 22 is provided. The drying chamber 22 has a cavity inside. After the heating box 14 and the fan 13 are started, the generated hot air will heat the hot cavity 16 and conduct the heat to the drying chamber 22, thereby drying the color masterbatch in the drying chamber 22.

[0035] like Figures 1-2 As shown, the drying chamber 22 is provided with a first inlet 23, through which the masterbatch to be dried is fed into the drying chamber 22. In order to achieve zoned drying to accommodate different types of masterbatch, the drying chamber 22 is also provided with a second inlet 24. At the same time, a heat insulation plate 27 is provided inside the drying chamber 22, which divides the drying chamber 22 into a first drying chamber and a second drying chamber. The masterbatch entering from the first inlet 23 will fall into the first drying chamber. Since it is in direct contact with the heat chamber 16, it will have a higher drying temperature, which is suitable for masterbatch with a higher drying temperature. Since the heat insulation plate 27 is provided between the second drying chamber and the heat chamber 16, the heat conduction to the second drying chamber will be slower, which is suitable for masterbatch that requires long-term low-temperature drying. The heat insulation plate 27 can be made of polystyrene board or other common heat insulation materials, which will not be described in detail in this embodiment.

[0036] The drying chamber 22 is provided with a first outlet 25 and a second outlet 26, wherein the first outlet 25 is connected to the first drying chamber and the second outlet 26 is connected to the second drying chamber. When the dried masterbatch is subsequently discharged, it can be discharged from the corresponding outlet. It should be noted that the drying chamber 22 can be inclined to facilitate the discharge of the masterbatch, or other conveying components can be provided. In this embodiment, they will not be described in detail.

[0037] To reduce calorie waste, such as Figure 1As shown, the heat cavity 16 is further provided with a reflux pipe 17, two ends of the reflux pipe 17 are connected with the heat cavity 16 respectively, and one-way valves are arranged at the two ends of the reflux pipe 17, in the drying process, the hot air in the heat cavity 16 can circulate and flow through the reflux pipe 17, the drying effect is increased, meanwhile, the heat waste is reduced, and the energy consumption is saved.

[0038] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and various modifications and changes can be made by those skilled in the art based on the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
