Technical Field

[0001] The utility model relates to the technical field of plastic masterbatch drying, in particular to an integrated device for drying and removing impurities from plastic masterbatch. Background Art

[0002] Masterbatch refers to the granular material obtained by mixing and kneading various required additives, fillers and a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation, and then through the process of metering, mixing, melting, extrusion, pelletizing and other processing by extruders and other equipment. It is called masterbatch.

[0003] Masterbatches will get damp during storage. When they are processed into other products, the damp masterbatches will affect the product quality. Generally, masterbatches need to be dried before melting. The traditional drying method is to pour the masterbatches into a drying box for drying, and the drying steps are complicated.

[0004] The applicant previously disclosed a plastic modified masterbatch drying device, with the publication (announcement) number CN217414576U, which achieved the drying effect by driving the masterbatch to move through airflow. However, it was found during use that since the masterbatch contained some debris, more dust would be generated during airflow drying, and the debris would not be removed, affecting the product quality. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that in the prior art, the drying effect is achieved by driving the movement of masterbatch by airflow, but it is found during use that since the masterbatch contains some debris, more dust will be generated during airflow drying, and the debris is not removed, which affects the product quality. Therefore, a plastic masterbatch drying and impurity removal integrated device is proposed.

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

[0007] A plastic masterbatch drying and impurity removal integrated device comprises a first straight tube, a second straight tube, and an air pump, wherein the end portion of the second straight tube is inserted into the first straight tube, a sealing arrangement is provided between the front end of the first straight tube and the outer wall of the middle portion of the second straight tube, an air flow gap channel is provided between the outer wall of the end portion of the second straight tube and the inner wall of the first straight tube, an air outlet end of the air pump is connected to the air flow gap channel, a U-shaped tube is connected and installed at the end portion of the first straight tube, impurity removal holes are provided on at least the outer circle of the circumference of the U-shaped tube, a breathable dust collecting bag is provided on the outside of the U-shaped tube, and the other end of the U-shaped tube is extended to a collection container through an extension tube.

[0008] One end of the breathable dust collecting bag is open, and a sealing portion is arranged at the open end of the breathable dust collecting bag. The breathable dust collecting bag is sleeved on the outside of the U-shaped tube through the open end, and is sealed with the U-shaped tube through the sealing portion.

[0009] The sealing part is a Velcro.

[0010] The outer wall of the first straight tube is located between the second straight tube and the U-shaped tube and is wound with a heating wire.

[0011] One end of the U-shaped tube is sleeved on the outer wall of the first straight tube, and the other end of the U-shaped tube is inserted into the inner wall of the extension tube.

[0012] The inner wall of the U-shaped tube is provided with a hemispherical protrusion.

[0013] The utility model proposes an integrated device for drying and removing impurities from plastic masterbatch, which has the beneficial effect that when the device moves the masterbatch into a U-shaped tube through airflow, since the U-shaped tube is a bent structure and is provided with impurity removal holes, under the action of impact and centrifugal force, part of the airflow carries debris and impurities through the impurity removal holes and is discharged to a breathable dust collecting bag, and part of the airflow carries the masterbatch particles through the U-shaped tube into a collecting container. The device can achieve both the drying effect and the impurity removal effect on the masterbatch, and has a simple structure and is practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figure 1 A plastic masterbatch drying and impurity removal integrated device comprises a first straight tube 3, a second straight tube 4, and an air pump 1. The end portion of the second straight tube 4 is inserted into the first straight tube 3. The front end of the first straight tube 3 and the outer wall of the middle portion of the second straight tube 4 are sealed. An air flow gap channel 5 is provided between the outer wall of the end portion of the second straight tube 4 and the inner wall of the first straight tube 3. The air outlet end of the air pump 1 is connected with the air flow gap channel 5. A U-shaped tube 7 is installed at the end of the first straight tube 3. At least the outer circle of the circumference of the U-shaped tube 7 is provided with impurity removal holes 8. A breathable dust bag 9 is provided on the outside of the U-shaped tube 7. The other end of the U-shaped tube 7 is extended to a collection container 12 through an extension tube 11.

[0018] The front end and the end mentioned in the text are defined according to the direction of airflow movement, with the upstream being the front end and the downstream being the rear end.

[0019] The front end of the second straight tube 4 is inserted into the box for storing the masterbatch, and the air pump 1 blows air into the airflow gap channel 5. The airflow flows in the airflow gap channel 5 between the second straight tube 4 and the first straight tube 3. After the airflow moves to the end of the second straight tube 4, a negative pressure area is formed at the end of the second straight tube 4. Under the action of the negative pressure, the second straight tube 4 generates suction, and the masterbatch is sucked into the second straight tube 4 and enters the second straight tube under the action of the suction. Then, as the airflow moves in the first straight tube 3, the airflow drives the masterbatch to move on the one hand, and can dry the masterbatch on the other hand. When the masterbatch moves into the U-shaped tube 7, since the U-shaped tube 7 is a bent structure and the U-shaped tube 7 is provided with a discharge hole 8, under the action of impact and centrifugal force, part of the airflow carries debris and impurities through the discharge hole 8 and is discharged to the breathable dust collecting bag 9, and part of the airflow carries the masterbatch particles through the U-shaped tube 7 into the collecting container 12. The device can achieve both the drying effect and the impurity removal effect of the masterbatch, and has a simple structure and is practical.

[0020] As an installation method of the breathable dust bag 9, one end of the breathable dust bag 9 is open, and a sealing portion 10 is provided at the open end of the breathable dust bag 9. The breathable dust bag 9 is sleeved on the outside of the U-shaped tube 7 through the open end, and is sealed with the U-shaped tube 7 through the sealing portion 10. The U-shaped tube 7 is sleeved inside the breathable dust bag 9, which can reduce the escape of dust into the workshop.

[0021] The sealing part 10 is a Velcro, and the breathable dust bag 9 is fixed by the Velcro, so that installation and disassembly are simple and convenient.

[0022] An electric heating wire 6 is wound around the outer wall of the first straight tube 3 between the second straight tube 4 and the U-shaped tube 7. The electric heating wire 6 heats the first straight tube 3 to improve the drying efficiency.

[0023] One end of the U-shaped tube 7 is sleeved on the outer wall of the first straight tube 3 , and the other end of the U-shaped tube 7 is inserted into the inner wall of the extension tube 11 . With this installation method, the masterbatch can pass through the U-shaped tube 7 smoothly.

[0024] In order to improve the separation effect of the masterbatch and the debris in the U-shaped tube 7 , a hemispherical protrusion is provided on the inner wall of the U-shaped tube 7 .

[0025] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technical solution, concept, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
