Description

Technical Field

[0001] This utility model relates to the field of modified plastics technology, and in particular to a modified plastics air dryer. Background Technology

[0002] Modified plastics are intermediate products in the petrochemical industry chain. They are plastic products that are processed by filling and other methods on the basis of general plastics to improve their flame retardancy, strength, toughness, etc. During processing, they usually need to be air-dried to reduce their internal moisture and make them more durable.

[0003] While existing modified plastic air dryers can dry modified plastics, in actual use, contact and collision between the modified plastics inevitably produce powdery particles. These particles are discharged from the exhaust vent with the hot air, easily contaminating the working environment. Therefore, it is necessary to invent a modified plastic air dryer to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a modified plastic air dryer to solve the problem mentioned in the background art that although the existing modified plastic air dryers can air dry modified plastics, in actual use, it is difficult to avoid the generation of powder particles from contact and collision between modified plastics. These powder particles will be discharged from the exhaust port with the hot air, which will easily pollute the working environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modified plastic air dryer, comprising an opening and closing drying chamber, a sealed feed inlet at the top of the opening and closing drying chamber, a stirring motor installed at the top of the opening and closing drying chamber, a stirring shaft installed at the bottom of the stirring motor, a sieve plate installed inside the opening and closing drying chamber, a collection drawer movably inserted into one side of the opening and closing drying chamber, two sets of air blowers symmetrically distributed on the outside of the opening and closing drying chamber, two sets of exhaust pipes symmetrically distributed on the top of the opening and closing drying chamber, a filter cap threadedly connected to the top of the exhaust pipe, a driven turbine movably connected inside the exhaust pipe, a cross cleaning rod fixedly connected to the top of the driven turbine, and multiple sets of elastic columns arranged in a cross pattern on the top of the cross cleaning rod.

[0006] Preferably, multiple sets of stirring blades are fixedly connected to the outer side of the stirring shaft, and the multiple sets of stirring blades are linearly distributed on the outer side of the stirring shaft.

[0007] Preferably, a scraper rod is fixedly connected to the outer side of the stirring shaft.

[0008] Preferably, two sets of drive motors are installed inside the blower, and the two sets of drive motors are linearly distributed inside the blower. A fan body is installed on one side of the output shaft of the drive motor, and a resistance wire coil is installed on one side of the fan body.

[0009] Preferably, two sets of filter plates are installed on one side of the blower, and the two sets of filter plates are linearly distributed on one side of the blower, and an air inlet slot is opened on one side of the blower.

[0010] Preferably, a bearing rod is installed at the bottom of the driven turbine shaft.

[0011] Preferably, a threaded ring is fixedly connected to the bottom of the filter cap, and a threaded groove is formed on the inner wall of the exhaust pipe.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By incorporating a sieve plate, scraper bar, collection drawer, exhaust pipe, filter cap, driven turbine, cross cleaning bar, elastic column, bearing rod, threaded ring, and threaded groove, this device can sieve modified plastic raw materials through the sieve plate, allowing powdered modified plastic to settle in the collection drawer for convenient centralized processing. The exhaust pipe is filtered through the filter holes on the filter cap, preventing modified plastic powder from entering the air and polluting the environment. Simultaneously, the driven turbine, driven by the exhaust air, rotates the elastic column on the cross cleaning bar along the bottom of the filter cap, preventing filter clogging and enabling self-cleaning, thus greatly improving the practicality of the device.

[0014] 2. By incorporating a stirring motor, stirring shaft, stirring blades, blower, drive motor, fan body, resistance wire coil, filter plate, and air inlet, the device can drive the stirring blades to rotate via the stirring motor, thereby thoroughly stirring the modified plastic. This prevents the modified plastic from piling up and ensures more even heating. The drive motor drives the fan body to rotate, generating airflow that blows onto the modified plastic, while the resistance wire coil heats the air, creating hot air for efficient drying of the modified plastic. The combination of these components significantly improves the drying efficiency of the device. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0022] This utility model provides, for example Figure 1-4The modified plastic air dryer shown includes a hinged drying chamber 1, which is the drying unit of the device. A sealed feed inlet 2 is located at the top of the drying chamber 1, serving as the feeding unit. A stirring motor 3 is installed at the top of the drying chamber 1, providing power for the stirring function of the device. A stirring shaft 4 is installed at the bottom of the stirring motor 3. A sieve plate 6 is installed inside the drying chamber 1, which can sieve the modified plastic powder. A collection drawer 8 is movably inserted into one side of the drying chamber 1, which can collect the modified plastic powder. Two sets of air blowers 9 are symmetrically distributed on the outside of the drying chamber 1, forming the main drying unit of the device. The top of the drying chamber 1... Two sets of exhaust pipes 15 are connected through the top of the opening and closing drying chamber 1. The two sets of exhaust pipes 15 are symmetrically distributed on the top of the opening and closing drying chamber 1. The two sets of exhaust pipes 15 are the discharge positions of the opening and closing drying chamber 1. The top of the exhaust pipe 15 is threaded with a filter cap 16, which can block the modified plastic powder in the air. The exhaust pipe 15 is movably connected with a driven turbine 17, which can rotate with the air flow to drive the cross cleaning bar 18. The top of the driven turbine 17 is fixedly connected to the cross cleaning bar 18. Multiple sets of elastic columns 19 are installed on the top of the cross cleaning bar 18. The multiple sets of elastic columns 19 are arranged in a cross shape on the top of the cross cleaning bar 18. The elastic material of the multiple sets of elastic columns 19 can penetrate into the filter holes on the filter cap 16, thereby squeezing out the particles that are blocking the filter holes to prevent clogging.

[0023] Multiple sets of stirring blades 5 are fixedly connected to the outside of the stirring shaft 4. The multiple sets of stirring blades 5 are linearly distributed on the outside of the stirring shaft 4. The use of multiple sets of stirring blades 5 can fully stir the modified plastic when the stirring shaft 4 rotates, thereby avoiding the situation where the modified plastic is piled up and cannot effectively contact the hot air, and at the same time avoiding uneven heating of the modified plastic.

[0024] A scraper rod 7 is fixedly connected to the outside of the stirring shaft 4. The scraper rod 7 can rotate with the stirring shaft 4, thereby rotating along the surface of the sieve plate 6 to improve the powder feeding efficiency.

[0025] The blower tube 9 is equipped with two sets of drive motors 10, which are linearly distributed inside the blower tube 9. A fan body 11 is mounted on the output shaft of one side of the drive motor 10, and a resistance coil 12 is mounted on one side of the fan body 11. When the two sets of drive motors 10 are powered on, they can drive the two sets of fan bodies 11 to rotate, thereby generating airflow to dry the modified plastic inside the chamber. When the resistance coil 12 is powered on, it can convert electrical energy into heat energy and heat the air around the fan body 11, thereby causing the fan body 11 to blow out hot air to dry the modified plastic, which greatly improves the drying efficiency of the device.

[0026] Two sets of filter plates 13 are installed on one side of the blower 9. The two sets of filter plates 13 are linearly distributed on one side of the blower 9. An air inlet slot 14 is opened on one side of the blower 9. The use of the two sets of filter plates 13 can block the air outlet of the blower 9 to prevent modified plastic powder from overflowing from the blower 9. The air inlet slot 14 improves the air intake efficiency of the blower 9 and further improves the drying efficiency of the device.

[0027] A bearing rod 20 is installed at the bottom of the shaft of the driven turbine 17. The use of the bearing rod 20 can support the driven turbine 17 above and realize the rotation of the driven turbine 17, thereby ensuring the rotation efficiency of the driven turbine 17 when the air flows.

[0028] A threaded ring 21 is fixedly connected to the bottom of the filter cap 16, and a threaded groove 22 is provided on the inner wall of the exhaust pipe 15. The threaded ring 21 can be threadedly connected to the threaded groove 22, thereby realizing the installation of the filter cap 16. This installation method has a firm fixing effect and is convenient for users to clean and disassemble later.

[0029] Working principle: The user opens the sealed inlet 2 and puts the modified plastic into the openable drying chamber 1. Then, the user sequentially powers on the stirring motor 3, drive motor 10, and resistance coil 12. When the stirring motor 3 is powered on, it drives multiple sets of stirring blades 5 to rotate via the stirring shaft 4, thus thoroughly stirring the modified plastic and ensuring even heating. When the drive motor 10 is powered on, it drives the fan body 11 to rotate via the output shaft, thus generating airflow that blows into the openable drying chamber 1 for drying. When the resistance coil 12 is powered on, it converts electrical energy into heat energy and heats the air around the fan body 11, causing the fan body 11 to blow out hot air to dry the modified plastic. The modified plastic is dried efficiently. Hot air and water vapor are discharged through the exhaust pipe 15, thus achieving the drying function. During the drying process, the contact and collision between the modified plastics can easily generate fine powder. This powder can fall into the collection drawer 8 below through the sieve holes on the sieve plate 6, which is convenient for users to collect and process. Some of the powder that is blown up by the hot air is blocked by the filter cap 16 on the exhaust pipe 15 and cannot be dispersed. Therefore, it can always stay in the openable drying chamber 1. After drying is completed and the powder settles, the collection drawer 8 can be taken out and the chamber door can be opened to take out the modified plastic before use. This achieves the functions of efficient dehumidification and dust overflow prevention of a modified plastic air dryer.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
