Description

Technical Field

[0001] This utility model relates to the field of color masterbatch production technology, and in particular to a dryer for color masterbatch raw materials. Background Technology

[0002] In the production and processing of masterbatch raw materials such as resins, the drying process is crucial, as its drying effect directly affects the quality and performance of the final product. Traditional dryers, such as the utility model patent with publication number CN220959323U, disclose a phenolic resin drying device, including a base plate. A storage tank is fixedly connected to the upper surface of the base plate. A heating coil is installed inside the storage tank. A rotating motor is installed above the storage tank. A stirring rod is fixedly connected to the output end of the rotating motor. The bottom end of the stirring rod penetrates through the storage tank and extends into the interior of the storage tank. Two heating tubes are fixedly connected to the outer surface of the storage tank. A controller is installed above the base plate. This utility model, by setting up a storage tank, can place phenolic resin. Using the controller, the rotating motor, heating tubes, and heating coil can be turned on. Simultaneously, the heating coil and heating tubes heat the phenolic resin inside the storage tank, drying it. The rotation of the rotating motor drives the stirring rod to rotate inside the storage tank, thereby causing the phenolic resin inside the storage tank to tumble from bottom to top. Because it only has an exhaust port at the top and the air intake method is not targeted, the flow path of hot air inside the cylinder is chaotic and cannot form an effective directional airflow. Humid air cannot be discharged from the cylinder in a timely and effective manner, and will accumulate inside the cylinder, forming a high humidity environment. This will hinder the further evaporation of moisture from the material and reduce the drying speed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dryer for color masterbatch raw materials. Compared to existing technologies, this dryer has air vents at both the top and bottom. Because hot air is less dense than cold air, it naturally rises, forming a directional airflow. The hot air introduced through the bottom air inlet flows upward inside the cylinder, directly penetrating the material layer, forming a hot air penetration drying process. This effectively removes humid air and improves drying efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A dryer for color masterbatch raw materials includes a barrel body. The barrel body has an annular cavity and a heating cavity inside. The bottom of the annular cavity and the bottom of the heating cavity are connected through multiple communication ports. The top of the annular cavity has multiple air inlets. The top of the heating cavity has an exhaust pipe. An annular heating plate is installed on the inner wall of the heating cavity. The top of the barrel body has a feeding port with a removable sealing cover.

[0005] Preferably, a support frame is installed at the lower end of the barrel.

[0006] Preferably, it further includes a disturbance mechanism, which includes two fixed rods symmetrically fixedly connected to the inner wall of the heating chamber. The opposite ends of the two fixed rods are jointly fixedly connected to a lifting cylinder. A drive motor is installed at the upper end of the cylinder. The output shaft of the drive motor extends into the heating chamber and is fixedly connected to a rotating shaft. The rotating shaft passes through the lifting cylinder and is equipped with a spiral blade.

[0007] Preferably, a plurality of agitator rods are fixedly connected at equal intervals to the outer side of the lower end of the rotating shaft.

[0008] Preferably, a discharge port is provided at the bottom of the heating chamber, and a manual valve is installed at the discharge port.

[0009] Preferably, two connecting rods are symmetrically fixedly connected to the top of the heating chamber, and a baffle plate is fixedly connected to the lower ends of the two connecting rods. The feeding port passes through the baffle plate, and the baffle plate and the inner wall of the heating chamber form a flow channel. A temperature-conducting ring that cooperates with the flow channel is fixedly connected to the inner wall of the heating chamber, and the outer side of the temperature-conducting ring extends into the annular cavity.

[0010] Compared with the prior art, the advantages of this utility model are as follows: 1. A unidirectional airflow is formed through the annular cavity, air inlet, connecting port, and exhaust pipe. Hot and humid air rises and is discharged, while outside air is supplied from the bottom, promoting the discharge of moist gas, accelerating the separation of moisture from the raw material, improving drying efficiency, and shortening drying time.

[0011] 2. The drive motor drives the rotating shaft, which causes the spiral blades to lift the material at the bottom to the top, realizing the material circulation. At the same time, the stirring rod enhances the material movement, improving the overall drying uniformity and product quality.

[0012] 3. The baffle plate and the inner wall of the heating chamber form a flow channel, concentrating the gas passing through the temperature-conducting ring and improving the heat exchange effect. The temperature-conducting ring heats the incoming air and recovers the heat energy of the exhaust air, reducing overall energy consumption. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 A dryer for color masterbatch raw materials includes a barrel 1, and a support frame 2 is installed at the lower end of the barrel 1. The support frame 2 can support the whole and ensure the stability of use. The barrel 1 has an annular cavity 7 and a heating cavity 8 inside. The bottom of the annular cavity 7 and the bottom of the heating cavity 8 are connected by multiple connecting ports 19. The top of the annular cavity 7 has multiple air inlets 6. The top of the heating cavity 8 has an exhaust pipe 4. In this way, when heating materials, the hot and humid air inside the heating cavity 8 rises and is discharged through the exhaust pipe 4. Air is replenished from the multiple connecting ports 19 at the bottom, generating a unidirectional airflow between the outside, the annular cavity 7, the bottom of the heating cavity 8, the top of the heating cavity 8, and the exhaust pipe 4. This airflow can promote the discharge of humid gas and improve the drying effect. Furthermore, an exhaust hose can be connected to the exhaust pipe 4 to guide the discharged gas away from the barrel 1 to prevent the humid gas from being drawn in again. An annular electric heating plate 17 is installed on the inner wall of the heating cavity 8. The inner top of the barrel 1 is provided with a feeding port 3, and a detachable sealing cover is installed on the feeding port 3. The detachable installation can be a snap-fit ​​connection, which is existing technology and will not be described in detail here. When feeding, the feeding port 3 is opened, and when drying, the feeding port 3 is closed. The inner bottom of the heating chamber 8 is provided with a discharge port 18, and a manual valve is installed at the discharge port 18. The discharge can be achieved by opening the manual valve. The system also includes a disturbance mechanism, which consists of two fixed rods 13 symmetrically fixed to the inner wall of the heating chamber 8. The opposite ends of the two fixed rods 13 are fixedly connected to a lifting cylinder 14. A drive motor 5 is installed at the upper end of the barrel 1. The output shaft of the drive motor 5 extends into the heating chamber 8 and is fixedly connected to a rotating shaft 12. The rotating shaft 12 passes through the lifting cylinder 14 and is equipped with a spiral blade 15. Multiple stirring rods 16 are fixedly connected at equal intervals to the outer side of the lower end of the rotating shaft 12. After the rotating shaft 12 is started, the spiral blades 15 can be used to lift the bottom material to the top, while the original top material falls to the bottom due to gravity, achieving the effect of material circulation and improving drying uniformity. Furthermore, the rotation of the stirring rods 16 can make the material more mobile. Two connecting rods 11 are symmetrically fixed to the top of the heating chamber 8. The lower ends of the two connecting rods 11 are fixedly connected to a baffle plate 10. The feeding port 3 passes through the baffle plate 10. The baffle plate 10 and the inner wall of the heating chamber 8 form a flow channel. A temperature-conducting ring 9 that cooperates with the flow channel is fixedly connected to the inner wall of the heating chamber 8. The outer side of the temperature-conducting ring 9 extends into the annular cavity 7. It should be noted that when the hot air is discharged upward, it will pass through the temperature-conducting ring 9. By using the flow channel, the gas passing through the temperature-conducting ring 9 can be more concentrated, improving the heat exchange effect. The temperature-conducting ring is made of a heat-conducting material, which can heat the incoming air after heat exchange. In this way, the actual temperature of the air that subsequently enters the bottom of the heating chamber 8 will not be too low. The heat energy recovery part of the discharged hot air reduces the actual overall energy consumption.

[0017] In this utility model, the detachable sealing cover is opened from the feeding port 3, and the color masterbatch raw material to be dried is put into the heating chamber 8 of the barrel 1 through the feeding port 3. Then the detachable sealing cover on the feeding port 3 is closed to ensure the sealing of the barrel 1. The annular heating plate 17 is activated, and it begins to work, heating the air inside the heating chamber 8. This gradually increases the temperature inside the heating chamber 8, providing a heat source for drying the masterbatch raw materials. During the heating process, the hot and humid air inside the heating chamber 8 rises due to its lower density and is discharged through the exhaust pipe 4. As the air inside the heating chamber 8 decreases, the pressure at the bottom decreases. Outside air enters the annular cavity 7 through multiple air inlets 6 at the top, and then replenishes the bottom of the heating chamber 8 through multiple connecting ports 19 at the bottom of the annular cavity 7, which connect to the bottom of the heating chamber 8. This forms a unidirectional airflow between the outside, the annular cavity 7, the bottom of the heating chamber 8, the top of the heating chamber 8, and the exhaust pipe 4. This airflow promotes the discharge of humid gas and improves the drying effect. The drive motor 5 is started, and its output shaft drives the rotating shaft 12 to rotate. The rotating shaft 12 passes through the lifting cylinder 14, and the spiral blades 15 mounted on it rotate with the rotating shaft 12, lifting the material at the bottom of the heating chamber 8 to the top; while the material originally at the top falls to the bottom under the action of gravity, realizing the circulation of the material and improving the uniformity of drying. In addition, multiple stirring rods 16 fixedly connected at equal intervals to the outer side of the lower end of the rotating shaft 12 rotate with the rotating shaft 12, further enhancing the mobility of the material. When the hot air flows upward and passes through the temperature-conducting ring 9, the baffle plate 10 and the inner wall of the heating chamber 8 form a flow channel, making the gas passing through the temperature-conducting ring 9 more concentrated and improving the heat exchange effect. The temperature-conducting ring 9 is made of a heat-conducting material, which heats the incoming air after heat exchange, so that the actual temperature of the air entering the bottom of the heating chamber 8 is not too low, and partially recovers the heat energy of the exhaust hot air, reducing the actual overall energy consumption. After drying is complete, open the manual valve installed at the discharge port 18, and the dried masterbatch raw material in the heating chamber 8 will be discharged through the discharge port 18, completing the entire drying process.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
