Description

Technical Field

[0001] The utility model relates to the technical field of homogenizing bins, in particular to an internal drying device for a masterbatch homogenizing bin. Background Art

[0002] Homogenization bins are often used for blending multiple batches of finished plastic pellets, a process that can effectively eliminate batch-to-batch differences. In the field of plastic processing and manufacturing, the homogeneity of raw materials is critical to the quality of the final product. Since there may be batch-to-batch differences in the production and supply of raw materials, such as color, density, melt index, etc., these differences, if not controlled, will directly affect the quality and consistency of the finished product. By blending multiple batches in a homogenization bin, different batches of plastic pellets can be mixed together to homogenize the characteristics of the raw materials. This mixing process helps to reduce color differences, balance physical properties, improve product quality, and enhance processing stability.

[0003] In some cases, the homogenization bin needs to have a drying function, for example: plastic pellets need to maintain a specific low humidity level before processing, because too high humidity will affect their processing performance and the quality of the final product. For example, materials such as nylon and PET need to be fully dried before processing; if plastic pellets are stored in a humid environment or exposed to a high humidity environment during transportation, they may need to be dried before being put into production; certain specific processing processes, such as injection molding or blow molding, have strict requirements on the humidity of the raw materials. In these cases, using dry raw materials can prevent problems during processing, such as surface defects, increased internal stress, etc.

[0004] In order to achieve the drying effect on the particles in the prior art, a hot air circulation system is generally directly connected to the homogenization bin, and the particles are dried by hot air flow while being stirred by a stirring rod. However, the contact uniformity between the hot air flow and the particles is not good in the above method, so the drying efficiency is relatively low and the drying is uneven. Utility Model Content

[0005] The utility model aims to improve the contact uniformity between the particles in the homogenizing bin and the hot air flow, and improve the drying efficiency and drying uniformity, and proposes a drying device inside the masterbatch homogenizing bin.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A drying device inside a masterbatch homogenizing bin comprises a homogenizing box, wherein the upper portion of the homogenizing box is provided with a feed port, the lower portion of the homogenizing box is provided with a discharge port, the homogenizing box is provided with a stirring mechanism, the drying device comprises a hot air circulation component, the stirring mechanism comprises at least one rotatable first spiral tube and at least one second spiral tube, the first spiral tube is connected to an air outlet end of the hot air circulation component and has an air outlet hole capable of blowing air into the homogenizing box, and the second spiral tube is connected to an air inlet end of the hot air circulation component and has an air inlet hole capable of extracting gas inside the homogenizing box.

[0008] The stirring mechanism comprises a first cylinder rotatably connected to the upper end of the homogenizing box and a second cylinder rotatably connected to the lower end of the homogenizing box, wherein the first cylinder and the second cylinder are coaxially arranged;

[0009] One end of the first spiral tube is fixedly connected to the first cylinder, and the other end is fixedly connected to the second cylinder, and the first spiral tube is connected to the air outlet end of the hot air circulation component through the second cylinder;

[0010] One end of the second spiral tube is fixedly connected to the first cylinder, and the other end is fixedly connected to the second cylinder, and the second spiral tube is connected to the air inlet end of the hot air circulation component through the first cylinder;

[0011] The first cylinder is transmission-connected to the motor; or the second cylinder is transmission-connected to the motor.

[0012] The hot air flow circulation component includes an air flow heating drying box and a circulating fan. The air inlet of the circulating fan is connected to a first plug-in tube through a pipeline, and the first plug-in tube is rotatably connected to the first cylinder. The air outlet of the circulating fan is connected to a second plug-in tube through the air flow heating drying box and a pipeline, and the second plug-in tube is rotatably connected to the second cylinder.

[0013] The first plug-in tube is plugged into the first cylinder, and a rotating bearing is installed between the two. The second plug-in tube is plugged into the second cylinder, and a rotating bearing is installed between the two.

[0014] The second cylinder is coaxially fixedly connected with a first pulley, the motor power output shaft is fixedly connected with a second pulley, and the first pulley is connected to the second pulley via a belt.

[0015] The utility model proposes an internal drying device for a master batch homogenizing bin, which has the beneficial effect that the device dries the particles inside the homogenizing box through a circulating hot air flow, so that the particles inside the homogenizing box are dried during the stirring process. Since the first spiral tube and the second spiral tube of the stirring tube are directly spraying and inhaling, the air flow can be better made to flow between the particles, thereby achieving a uniform drying effect on the particles.
