Description

Technical Field

[0001] This utility model relates to the field of PE sheath material processing technology, and in particular to a PE sheath material processing mixing tank with drying function. Background Technology

[0002] PE granules are plastic granules made from high-pressure polyethylene. In the production and processing of PE sheath material, mixing is a crucial step. Its purpose is to fully and uniformly mix various raw materials such as PE resin, color masterbatch, antioxidant, and plasticizer to ensure the stability of the final product's performance and the consistency of its appearance. The quality of mixing directly affects the subsequent extrusion granulation and even the quality of the finished sheath material.

[0003] During the mixing process, dust is easily generated when feeding and stirring. At the same time, the raw materials themselves may also adsorb fine particulate impurities from the environment. Existing mixing tanks are usually just closed containers, whose function is focused on removing moisture from the raw materials, while neglecting dust removal. The dust and impurities raised by stirring cannot be discharged and will continue to mix in the raw materials, or settle back into the raw materials after the machine is stopped, resulting in impurities in the finished product, affecting the smoothness and insulation performance of the sheath material.

[0004] In response to this technical problem, this application proposes a PE sheath material processing mixing tank with drying function. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a PE sheath material processing mixing tank with a drying function. This tank can carry away and collect the fine dust raised during the mixing process, as well as the light impurities adsorbed by the raw materials themselves, with the airflow. The detachable scraper can be quickly replaced or cleaned.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A PE sheath material processing mixing tank with drying function includes a mixing tank, an air cavity sleeved on the outer wall of the mixing tank, a protective shell on the top side of the mixing tank, a motor installed at the middle of the top side of the mixing tank, a bevel gear one fixedly connected to the drive end of the motor, a bevel gear two meshing with the front side of the bevel gear one, a rotating rod fixedly connected to the front side of the bevel gear two, a gear fixedly connected to the front side of the rotating rod, a guide tube fixedly connected to the top side of the mixing tank, and a filter assembly provided at the middle end of the guide tube.

[0007] Furthermore, the filter assembly includes a filter pipe fixedly connected to the middle end of the conduit, an installation ring rotatably connected to the outer wall of the filter pipe, a transmission component fixedly connected to the outer wall of the installation ring, the transmission component meshing with a gear, and a protrusion one fixedly connected to the front side of the transmission component, the number of the protrusion one being multiple.

[0008] Furthermore, a bracket is fixedly connected to the inner wall of the filter pipe, and a spring is fixedly connected to the middle end of the bracket. There are multiple springs. A connecting rod is provided at the middle end of the bracket. A limit plate is fixedly connected to the rear side of the connecting rod. A filter layer is fixedly connected to the front side of the connecting rod. A second protrusion is fixedly connected to the outer wall of the filter layer. There are multiple second protrusions.

[0009] Furthermore, a rotating shaft is fixedly connected to the bottom side of the bevel gear, and a stirring rod is fixedly connected to the outer wall of the rotating shaft. There are multiple stirring rods, and a T-shaped protrusion is inserted into the side of the stirring rod away from the rotating shaft. A scraper is fixedly connected to the side of the T-shaped protrusion near the inner wall of the mixing tank.

[0010] Furthermore, a dust collection box is fixedly connected to the output end of the duct, and a hot air blower is fixedly connected to the input end of the air cavity through an air inlet pipe.

[0011] Furthermore, the mixing tank has air inlets around its bottom for blowing in hot air.

[0012] Furthermore, an electric valve is installed at the middle end of the conduit, and the output end of the electric valve is fixedly connected to the input end of the filter pipe through the conduit.

[0013] Furthermore, a support foot is fixedly connected to the bottom side of the mixing tank to stably support the mixing tank.

[0014] This utility model has the following beneficial effects: 1. In this utility model, hot air is blown in from the bottom of the tank. During the mixing process, it can not only effectively dry the moisture on the surface of the raw materials, but also carry away the fine dust raised during the mixing process, as well as the light impurities adsorbed by the raw materials themselves, with the airflow. This reduces the impurity content in the mixture and improves the quality of the final product. At the same time, the dust-laden airflow is filtered and collected to avoid the pollution of the environment caused by the discharge of dust.

[0015] 2. In this utility model, an installable and detachable scraper is used to scrape off the adhesive that may adhere to the inner wall of the mixing tank, avoiding the formation of scale on the inner wall of traditional equipment. Moreover, the scraper can be quickly replaced or cleaned according to the wear condition, which greatly reduces the maintenance cost and time of the equipment and ensures the continuity and stability of production.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 and Figure 3This utility model provides an embodiment of a PE sheath material processing mixing tank with drying function, including a mixing tank 1. An air chamber 2 is fitted on the outer wall of the mixing tank 1, through which hot air can be introduced to dry the material inside the tank. A protective shell 3 is provided on the top side of the mixing tank 1 to protect the internal transmission components. A motor is installed at the middle of the top side of the mixing tank 1. A bevel gear 11 is fixedly connected to the drive end of the motor. A bevel gear 12 is meshed with the front side of the bevel gear 11. A rotating rod 13 is fixedly connected to the front side of the bevel gear 12. A gear 14 is fixedly connected to the front side of the rotating rod 13. The transmission component 17 can drive the filter assembly to move. The top side of the mixing tank 1 is fixedly connected to the conduit 7. The middle end of the conduit 7 is equipped with the filter assembly for separating dust. The output end of the conduit 7 is fixedly connected to the dust collection box 5. The middle end of the conduit 7 is equipped with an electric valve 10. The electric valve 10 is externally controlled to open or close at a fixed time to close the air duct so that the dust that vibrates off the filter layer 15 can fall smoothly into the dust collection box 5. The output end of the electric valve 10 is fixedly connected to the input end of the filter pipe 9 through the conduit 7. The bottom side of the mixing tank 1 is fixedly connected to the support foot 4 for stable support of the mixing tank 1.

[0020] Reference Figure 4 , Figure 5 and Figure 7 The filter assembly includes a filter pipe 9 fixedly connected to the middle end of the conduit 7. A mounting ring 16 is rotatably connected to the outer wall of the filter pipe 9. A transmission component 17 is fixedly connected to the outer wall of the mounting ring 16. The transmission component 17 meshes with a gear 14, enabling the movement of multiple components to be controlled by a single motor. Multiple protrusions 18 are fixedly connected to the front side of the transmission component 17. A bracket 23 is fixedly connected to the inner wall of the filter pipe 9. Multiple spring pieces 21 are fixedly connected to the middle end of the bracket 23. A connecting rod 20 is provided at the middle end of the bracket 23. A limiting plate 22 is fixedly connected to the rear side of the connecting rod 20, and a filter layer 15 is fixedly connected to the front side of the connecting rod 20. A second protrusion 19 is fixedly connected to the outer wall of the filter layer 15. There are multiple second protrusions 19. When the transmission component 17 rotates, it drives the first protrusion 18 to move. The first protrusion 18 and the second protrusion 19 collide, causing the filter layer 15 to vibrate. This can vibrate and dislodge the dust adhering to the surface of the filter layer 15, preventing blockage of the air outlet. The elastic force generated by the spring piece 21 is transmitted to the connecting rod 20, which can increase the vibration amplitude of the filter layer 15 and enhance its dust removal ability.

[0021] Reference Figure 6 A rotating shaft is fixedly connected to the bottom side of the bevel gear 11, and a stirring rod 24 is fixedly connected to the outer wall of the rotating shaft. There are multiple stirring rods 24. A T-shaped protrusion 25 is inserted into the side of the stirring rod 24 away from the rotating shaft. A scraper 26 is fixedly connected to the side of the T-shaped protrusion 25 near the inner wall of the mixing tank 1. The T-shaped insertion structure allows the scraper 26 to be easily disassembled, cleaned or replaced without tools.

[0022] Reference Figure 2 The input end of the air chamber 2 is fixedly connected to the hot air blower 6 through the air inlet pipe 8. The bottom of the mixing tank 1 is provided with air inlets around the perimeter. The downward-facing air inlets allow hot air to be blown into the bottom of the tank, drying the material from bottom to top and ensuring the drying effect.

[0023] Working principle: During mixing, the top cover is opened to add materials. After adding materials, the motor and hot air blower 6 are started. The motor drives the first bevel gear 11 to rotate, which in turn drives the rotating shaft and the second bevel gear 12 to rotate. The rotating shaft drives the stirring rod 24 to mix the raw materials. The scraper 26, which is inserted at the end of the stirring rod 24, can tightly adhere to the inner wall of the mixing tank 1 and rotate to scrape off the adhering material on the inner wall of the mixing tank 1. The hot air blower 6 enters the air chamber 2 through the air inlet pipe 8 and enters the tank through the air inlets opened around the mixing tank 1 to heat and dry the raw materials. At the same time, the dust and impurities stirred up by the stirring enter the duct 7 at the top of the mixing tank 1 and further enter the filter. Pipe 9, bevel gear 12 drives gear 14 to rotate synchronously through rotating rod 13, which in turn drives transmission component 17 meshing with gear 14 to rotate. The rotation of transmission component 17 drives protrusion 18 to move. Protrusion 18 collides with protrusion 29, causing filter layer 15, which is fixedly connected to protrusion 29, to vibrate. While the filter layer 15 vibrates, the motion is transmitted to spring 21 through connecting rod 20. Spring 21 generates elastic force to further enhance the vibration effect of filter layer 15, causing dust and impurities attached to filter layer 15 to fall off and fall into dust collection box 5. When disassembling and replacing scraper 26, T-shaped protrusion is aligned with T-shaped groove at the end of stirring rod 24 and inserted for fixation.
