Description

Technical Field

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

[0002] Masterbatches, also known as color masterbatches or pigment particles, are tiny particles used to color or dye plastics and other materials. They are usually composed of pigments, carrier resins and auxiliary additives. The main function of masterbatches is to introduce color, color effects or specific performance characteristics into plastics, rubbers, coatings and other materials to meet the needs of different industries and applications. The preparation of masterbatches usually involves dispersing the pigment or colorant in an appropriate carrier to form tiny particles that are easy to disperse evenly in the material.

[0003] Color powder is one of the raw materials required for preparing masterbatch. This powder usually includes pigment or colorant particles and particles for carrier resin, which are mixed, dispersed and processed to form colorful or functional masterbatch. The powder used for masterbatch processing can include different types of pigments or colorants to achieve specific color effects or performance improvements.

[0004] However, due to the influence of environmental humidity and differences in processing techniques during the processing, the color powder is likely to contain a high amount of moisture. If it is not removed in time, it will easily affect the subsequent production of the product. The use of a drying box can easily cause the local temperature of the powder to be too high, resulting in insufficient final drying effect. At the same time, excessively high temperatures may cause local oxidation and fading of the powder, affecting subsequent production. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 As shown, the disturbance drying structure includes a blower 6 arranged on one side of the drying device shell 1, the air outlet end of the blower 6 is connected to an air outlet pipe 10, the other end of the air outlet pipe 10 penetrates the side wall of the drying device shell 1 and is obliquely arranged, and the air outlet pipe 10 is located in the drying device shell 1. One end is provided with a plurality of electric heating wires 15; an air guide groove 9 is opened on the inner wall of the drying device shell 1, and the air guide groove 9 is a spiral groove, and a plurality of air outlet holes 4 are opened on the upper cover 2, and the diameter of the air outlet hole 4 is smaller than the diameter of the powder particles.

[0024] As an optimization scheme of the utility model, gas is blown out by the blower 6, and then the air outlet pipe 10 sends the gas into the drying device shell 1. In this process, the electric heating wire 15 heats the air, and then the blown air spirals and rises along the air guide groove 9, while driving the powder to rise. When the powder flies to the middle of the drying device shell 1, it falls back to the bottom due to gravity, thereby maintaining the circulation and flipping of the powder. At the same time, the high-temperature gas evaporates the moisture in the powder and takes it away, and discharges it from the air outlet 4.

[0025] See also Figure 1-Figure 4 As shown, the automatic scraping structure includes a motor 5 arranged on the upper cover 2, the output end of the motor 5 passes through the upper cover 2 and is connected to a rotating shaft 11, and a plurality of scrapers 12 are equally installed around the rotating shaft 11.

[0026] As an optimization solution of the utility model, the motor 5 can drive the rotating shaft 11 to rotate, and then drive the scraper 12 to rotate, so as to scrape off the powder attached to the upper cover 2 to prevent it from blocking the air outlet 4.

[0028] As an optimization solution of the utility model, water droplets in the powder fall into the water storage bin 14 through the drainage hole 13. At the same time, closing the manual valve 8 during the drying process can keep the air pressure inside the water storage bin 14 stable and prevent gas from flowing out of the drainage pipe 7. After the drying is completed, the manual valve 8 can be opened to discharge the water in the water storage bin 14 through the drainage pipe 7.

[0029] See also Figure 1-Figure 4 As shown, a plurality of buckles 3 are provided at the mounting position of the upper cover 2 and the drying device housing 1 ; a sealing ring is provided on the inner side of the upper cover 2 .

[0030] As an optimization solution of the utility model, the buckle 3 can be used to facilitate the removal of the upper cover 2, and the sealing ring can ensure that the installation position of the upper cover 2 remains sealed during the drying process to prevent the powder from leaking out of the installation position.

[0031] The use process of this utility model:

[0032] First, close the manual valve 8, then open the buckle 3, open the upper cover 2, and pour the powder to be dried into it and then lock the upper cover 2, then turn on the blower 6 and the motor 5, and energize the heating wire 15 to start drying;
