Description

Technical Field

[0001] This utility model relates to the field of plastic drying, and in particular to a modified polyethylene plastic drying device. Background Technology

[0002] Polyethylene, as a general-purpose plastic, is widely used due to its excellent chemical stability, processing performance, and low cost. However, ordinary polyethylene has shortcomings in certain properties, such as mechanical strength, heat resistance, and UV resistance, making it difficult to meet the needs of high-end applications.

[0003] An existing patent application with patent number 202122855726.1 discloses an energy-saving drying device for modified polyethylene plastic, which includes a drying tank, a feed pipe, a discharge pipe, a motor, a shaft disc, a stirring shaft, and an air inlet pipe. It also includes a stirring mechanism and an exhaust mechanism. The stirring mechanism consists of a stirring rod, a finned plate, a vertical rod, rake teeth, and a spiral blade. The stirring shaft extends downward into the drying tank below the shaft disc, and a spiral blade is welded to the bottom end of the stirring shaft inside the drying tank. The stirring rod is symmetrically protruding on the outside of the stirring shaft above the spiral blade, and finned plates are welded between the stirring rods.

[0004] Current drying devices use fixed air vents, which results in poor moisture removal from the modified polyethylene granules accumulated inside the tank. Furthermore, insufficient contact between the hot air and the granules affects the drying efficiency. Therefore, a modified polyethylene plastic drying device is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a modified polyethylene plastic drying device. Through the synergistic effect of multi-channel air jetting, synchronous stirring and turning, and built-in adsorbent, the device achieves efficient and uniform drying of modified polyethylene plastic particles, effectively eliminating drying dead corners. The exhaust shells on both sides can quickly expel moisture, significantly improving the drying efficiency and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modified polyethylene plastic drying device, comprising a tank and a drying unit:

[0007] Tank body: A material pump is installed at the discharge port at the bottom. The top surface of the tank body is installed corresponding to the bottom surface of the tank cover. A material inlet is opened on the rear side of the tank body.

[0008] Drying unit: includes an air supply pipe, a fan, an air distribution valve, a main air jet pipe and auxiliary air jet pipes. The air outlet of the fan is connected to one end of the air supply pipe, and the other end of the air supply pipe is connected to the air inlet of the air distribution valve. There are two auxiliary air jet pipes, which are fixed on both sides of the bottom surface of the tank cover. The air outlets on both sides of the air distribution valve are connected to the air inlets of the two auxiliary air jet pipes, and the air outlet on the bottom surface of the air distribution valve is connected to the air inlet of the main air jet pipe.

[0009] It also includes a controller, which is fixed to the surface of the tank. The input terminals of the blower, air distribution valve and material pump are electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power source.

[0010] The fan is started to deliver air into the air distribution valve and distribute it evenly to the main jet pipe and the auxiliary jet pipe. This allows the air to dry both the inside and outside of the modified polyethylene plastic granules simultaneously, thus solving the problem of poor drying effect of fixed air outlets.

[0011] Furthermore, the drying unit also includes a cover, a heating tube, a temperature controller, and a heating shell. The heating shell is fixedly connected to the outside of the gas supply pipe. The right side of the heating shell is fitted into the left side of the cover. The heating tube is installed on the left side of the cover. The temperature controller is fixed to the front side of the heating shell. The input end of the heating tube is electrically connected to the output end of the temperature controller. The input end of the temperature controller is electrically connected to the output end of the controller. Activating the temperature controller adjusts the temperature of the heating tube, thereby heating the passing air and improving the drying efficiency of the modified polyethylene plastic particles inside the tank.

[0012] Furthermore, the drying unit also includes a toothed ring, a motor, gears, a frame, a shaft seat, and a stirring rack. The frame is fixed to the top surface of the tank cover, and a motor is mounted on the top surface of the frame. The output shaft of the motor is connected to the middle of the top surface of the gear. The shaft seat is rotatably mounted inside a through hole on the top surface of the tank cover.

Stirring racks that fit against the inner wall of the tank are mounted at both ends of the outer side of the shaft seat. The through groove inside the shaft seat is inserted into the main jet pipe. The input end of the motor is electrically connected to the output end of the controller. Starting the motor drives the gear to mesh with the toothed ring, which in turn drives the stirring rack to rotate, thereby agitating the modified polyethylene plastic particles inside the tank to improve the drying effect.

[0013] Furthermore, the drying unit also includes a fixing base, bolts, mounting blocks, an adsorbent box, and a box plate. The fixing base is fixed to the side of the stirring frame. Mounting blocks are provided at both ends of the inner side of the adsorbent box. The mounting blocks are inserted into the interior of the fixing base. The bolts pass through the through holes on the top surface of the fixing base and are threaded into the screw holes in the middle of the mounting blocks. The box plate is slidably inserted into the surface of the adsorbent box. The mounting blocks are installed into the interior of the fixing base using bolts. In this way, during the rotation of the stirring frame, the adsorbent inside the adsorbent box adsorbs the moisture inside the tank.

[0014] Furthermore, it also includes an electric telescopic rod, a baffle, and an exhaust shell. There are two exhaust shells, each connected to the bottom of the outer side of the tank. An electric telescopic rod is installed on the top surface of the exhaust shell. The outer end of the electric telescopic rod is connected to the inner side of the baffle. The input end of the electric telescopic rod is electrically connected to the output end of the controller. Activating the electric telescopic rod drives the baffle to move, thereby adjusting the size of the exhaust shell opening to accelerate the discharge of moisture.

[0015] Furthermore, it also includes a temperature and humidity sensor, which is installed on the surface of the tank and has its detection probe located inside the tank. The output of the temperature and humidity sensor is electrically connected to the input of the controller. The temperature and humidity sensor can detect the temperature and humidity inside the tank, thereby adjusting the airflow to improve drying efficiency.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This modified polyethylene plastic drying device has the following advantages:

[0017] 1. By starting the fan, air is delivered into the air distribution valve and evenly distributed to the main jet pipe and the auxiliary jet pipe. This allows the air to dry both the inside and outside of the modified polyethylene plastic granules simultaneously. The temperature controller is activated to adjust the temperature of the heating element, which heats the passing air, thereby improving the drying efficiency of the modified polyethylene plastic granules inside the tank and solving the problem of poor drying effect from fixed air outlets.

[0018] 2. By starting the motor, the gear meshes with the toothed ring, which drives the stirring frame to rotate. During the rotation of the stirring frame, the adsorbent inside the adsorbent box installed on the outside adsorbs the moisture inside the tank, thereby agitating the modified polyethylene plastic particles inside the tank to improve the drying effect.

[0019] 3. By activating the electric telescopic rod, the baffle is moved, thereby adjusting the size of the exhaust shell opening to accelerate the discharge of moisture. The temperature and humidity sensor can detect the temperature and humidity inside the tank, thereby adjusting the air volume to improve drying efficiency. Attached Figure Description

The output end of the temperature and humidity sensor 8 is electrically connected to the input end of the controller 9. The temperature and humidity sensor 8 can detect the temperature and humidity inside the tank 1, thereby adjusting the air volume to improve the drying efficiency.

[0031] The working principle of the modified polyethylene plastic drying device provided by this utility model is as follows: First, the modified polyethylene plastic granules enter the interior of the tank 1 through the feeding port. The blower 22 is started to deliver air into the air distribution valve 23, and the air is evenly distributed to the main jet pipe 24 and the auxiliary jet pipe 25. This allows the air to simultaneously dry the inside and outside of the modified polyethylene plastic granules. The temperature controller 28 is activated to adjust the temperature of the heating tube 27, thereby heating the passing air and improving the drying efficiency of the modified polyethylene plastic granules inside the tank 1. To address the issue of poor drying effect from fixed air vents, during the drying process, motor 211 is activated to drive gear 212 to mesh with toothed ring 210, which in turn drives stirring frame 215 to rotate. The adsorbent inside adsorbent box 219 on the outside of stirring frame 215 adsorbs moisture inside tank 1, thereby agitating the modified polyethylene plastic granules inside tank 1 to improve the drying effect. Electric telescopic rod 5 is activated to move baffle 6, thereby adjusting the opening size of exhaust shell 7 to accelerate the discharge of moisture. After the modified polyethylene plastic granules are dried, material pump 4 is activated to discharge them.
