Description

Technical Field

[0001] This application relates to the field of drying equipment technology, and in particular to a high-efficiency hot air circulating drying device. Background Technology

[0002] In industrial production, ultrasonic cleaning technology is used to remove debris after parts are processed. Then, drying is used to remove the moisture attached to the surface of the parts in time, otherwise the parts will rust. Traditional drying usually uses natural air drying or resistance wire heating. However, natural air drying takes a long time, is inefficient, and is greatly affected by weather and environmental factors. While resistance wire heating is relatively fast, it consumes a lot of energy, and due to uneven heating, it is easy to cause inconsistent drying quality of products, or even local overheating damage.

[0003] In current industrial production, drying equipment is often used to dry processed parts. The parts to be dried are placed inside the drying equipment, and hot air is generated by heating components to dry the objects. However, existing hot air circulating drying equipment generally suffers from poor hot air circulation, resulting in uneven distribution of hot air within the drying chamber, unsatisfactory drying effect, and thus affecting the drying quality. Utility Model Content

[0004] To improve the drying efficiency of parts after cleaning, this application provides a high-efficiency hot air circulation drying device.

[0005] The high-efficiency hot air circulating drying device provided in this application adopts the following technical solution:

[0006] A high-efficiency hot air circulating drying device includes a main body and a drying chamber disposed within the main body. The drying chamber comprises an inner shell and an outer shell. The inner shell contains a drying space for placing parts to be dried. A heating cavity is formed between the inner shell and the outer shell. A heating component and a hot air circulation mechanism are disposed within the heating cavity. The hot air circulation mechanism includes a motor mounted on the main body. An impeller is fixedly connected to the output shaft of the motor. The rotation axis of the impeller is vertically oriented. A guide plate is disposed on the outer side of the impeller. An air inlet is disposed at the bottom of the guide plate, communicating with the drying space. An air outlet is disposed on the side of the guide plate, communicating with the heating cavity through the inner shell. Through holes for connecting the drying space and the heating cavity are provided on the left and right side walls of the inner shell.

[0007] By adopting the above technical solution, the drying oven is set as a double-layer structure, and a heating component and a hot air circulation mechanism are set between the inner shell and the outer shell. During the drying operation, the heating component generates high-temperature hot air, and then the hot air circulation mechanism sends the hot air into the oven. The cooled hot air after heat exchange is returned to the heating system for reheating, forming a continuous cycle. This ensures that the hot air is evenly distributed in the oven, achieving efficient drying of parts while reducing energy consumption, making the entire drying operation more energy-efficient and environmentally friendly.

[0008] Preferably, the heating assembly includes several groups of heating tubes evenly arranged within the heating cavity.

[0009] By adopting the above technical solution and using multiple sets of heating tubes as heating components, a large amount of high-temperature hot air can be generated in a short time, which makes the flow path of hot air in the heating cavity smoother, ensuring the uniform distribution of hot air in the heating cavity, improving the efficiency and quality of drying operations, and also providing strong support for subsequent hot air circulation and parts drying.

[0010] Preferably, several sets of mounting holes are provided on the left and right sides of the upper end face of the outer shell, corresponding to the main body, and the heating tube is detachably installed to the outer shell and the main body through the mounting holes.

[0011] By adopting the above technical solution, operators can adjust the drying temperature or power by increasing or decreasing the number of heating tubes, thereby enabling the drying device to adapt to the drying needs of different types and quantities of parts, further improving the practicality of the device. In addition, this detachable setting also makes the maintenance and replacement of heating tubes more convenient, thus ensuring the normal operation of the drying device.

[0012] Preferably, the inner shell is provided with an air outlet pipe, one end of which is connected to the drying space and the other end is connected to the outside.

[0013] By adopting the above technical solution, during the drying operation, as the hot air circulation mechanism continues to operate, the moisture on the surface of the material is rapidly evaporated, forming hot and humid gas. Through the guidance of the exhaust pipe, the hot and humid gas generated during the drying process can be smoothly discharged to the outside of the drying chamber, thereby avoiding interference with the drying effect and making the drying process more efficient and stable.

[0014] Preferably, several sets of drying trays for placing parts to be dried are arranged in parallel within the drying space.

[0015] By adopting the above technical solution, the stability of the parts during the drying process is ensured, and damage caused by sliding or tipping is avoided. At the same time, the space inside the drying chamber is divided into multiple areas by the drying trays, so that the space inside the drying chamber is fully utilized, and a large number of parts to be dried can be processed at the same time, which not only improves production efficiency, but also reduces operating costs.

[0016] Preferably, the inner shell has several sets of opposing support frames movably arranged along the height direction on both sides of the drying space. The side walls of the drying space have multiple hanging holes evenly arranged in the horizontal and vertical directions. The support frames have hooks that cooperate with the hanging holes. The drying tray is slidably arranged on both sides of the two opposing support frames.

[0017] By adopting the above technical solution, the staff can adjust the installation position of the support frame according to the height of the parts to be dried, adapting to different parts to be dried. In addition, the multiple movable drying trays divide the inside of the drying box into multiple areas, enabling the simultaneous drying of multiple parts to be dried and improving work efficiency.

[0018] Preferably, a door is provided on the side of the main body corresponding to the drying chamber, and a baffle plate for blocking hot air is movably provided above the door.

[0019] By adopting the above technical solution, when the parts are removed after the drying operation, the baffle can effectively block the hot air in the drying chamber, thereby preventing the hot air from directly baking the main body, protecting the integrity and service life of the main body. In addition, the baffle can be easily replaced when it is damaged or worn during use, thereby reducing the maintenance cost of the equipment.

[0020] Preferably, the drying tray is provided with through holes.

[0021] By adopting the above technical solution, the through holes set on the drying tray can effectively increase the contact area between hot air and the parts to be dried, improve heat exchange efficiency, further enhance drying speed and uniformity, ensure that every corner can be fully dried, and avoid quality problems caused by insufficient drying in some areas. At the same time, the design of the through holes can also reduce the turbulence of hot air in the drying space, reduce energy consumption, and optimize the overall drying effect.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application achieves uniform and efficient drying of the parts to be dried by combining the heating component with the hot air circulation system, thereby improving the drying efficiency and quality of the device. In addition, by detachably mounting the heating component on the outer shell, the drying temperature or power can be adjusted, so that the drying device can adapt to the drying needs of different types and quantities of parts.

[0024] 2. This application achieves simultaneous processing of a large number of parts to be dried by detachably setting multiple drying trays inside the drying oven, thereby improving production efficiency. The detachable setting allows the staff to adjust the height and position of the support frame according to actual needs, thus meeting the needs of parts of different sizes to be dried.

[0025] 3. By installing a baffle on the main body, this application avoids hot air directly acting on the main body, thereby reducing the maintenance cost of the equipment and improving the utilization rate of the device. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] Reference Figure 1 and Figure 2This application discloses a high-efficiency hot air circulation drying device, including a main body 1, a drying box 2 inside the main body 1, the drying box 2 including an inner shell 21 and an outer shell 22 framed on the inner shell 21, a heating cavity 3 naturally formed between the inner shell 21 and the outer shell 22, a drying space is provided inside the inner shell 21, and a heating component 4 and a hot air circulation mechanism 5 are provided inside the heating cavity 3.

[0034] Reference Figure 2 and Figure 3 The heating component 4 includes multiple sets of heating tubes 41; several sets of mounting holes 6 are respectively provided on the left and right sides of the upper end face of the outer shell 22 and on the body 1. The heating tubes 41 pass through the corresponding sets of mounting holes 6, and the heating tubes 41 are threaded with nuts above the mounting holes 6 to fix the heating tubes 41. The heat-releasing part of the heating tubes 41 is located in the heating cavity 3. The hot air circulation mechanism 5 includes a motor 51, an impeller 52, and a guide plate 53. The motor 51 is located on the rotation shaft of the impeller 52 and is fixedly connected to the output shaft of the motor 51. The main body of the motor 51 is located at the upper end of the outer shell 22.

[0035] Reference Figure 3 and Figure 4 The upper end of the drying space is also horizontally provided with a partition 7. The impeller 52 is located between the inner shell 21 and the partition 7. The guide plate 53 surrounds the outside of the impeller 52 and is fixedly installed on the upper side wall of the inner shell 21. The bottom of the guide plate 53 forms an air inlet 8 for the impeller 52 to enter the air. The partition 7 is also provided with a hurricane cover 9 that cooperates with the air inlet 8. The side of the guide plate 53 is provided with an air outlet 10 that is fixedly connected to the side wall of the inner shell 21. The air outlet 10 is connected to the reinforced cavity. The left and right side walls of the inner shell 21 located below the partition 7 are provided with through holes 11 for connecting the drying space and the heating cavity 3.

[0036] Reference Figure 2 and Figure 3 The main body 1 is also equipped with an air outlet pipe 12. One end of the air outlet pipe 12 passes through the partition 7 and is connected to the drying space, while the other end is connected to the outside.

[0037] Reference Figure 3 and Figure 4During the drying process, the parts to be dried are placed in the drying space of the drying chamber 2, and the heating tube 41 generates high-temperature hot air in the heating cavity 3. Guided by the guide plate 53, the air generated by the impeller 52 is blown into the heating cavity 3 through the air outlet 10, allowing the high-temperature hot air in the heating cavity 3 to enter the drying space through the through hole 11. This causes the moisture on the surface of the parts to be dried to be rapidly evaporated, forming humid and hot gas. Guided by the air outlet 12, the humid and hot gas is discharged to the outside of the drying chamber 2. Subsequently, the hurricane cover 9 allows the cooled hot air after heat exchange to return to the heating system through the air inlet 8. The system reheats the parts, creating a continuous cycle that ensures even distribution of hot air within the drying chamber 2. This achieves efficient drying of the parts while reducing energy consumption, making the drying process more efficient and stable. By setting the mounting holes 6, operators can adjust the number of heating tubes 41, thereby adjusting the drying temperature or power. The heating tubes 41 then generate hot air, which continuously circulates and penetrates into the drying chamber 2 through the through holes 11. This reduces the temperature gradient inside the drying chamber 2, ensuring uniform heating of the materials during the drying process and thus improving drying efficiency.

[0038] Reference Figure 1 To further improve the safety of the device and extend its service life, a door is provided on the main body 1 in the area corresponding to the drying chamber 2, and a baffle plate 13 is provided on the main body 1 above the door. A control panel is provided on one side of the main body 1, which is equipped with a temperature controller and a digital power meter. During the drying process, the temperature, current and voltage are monitored in real time using the temperature controller and the digital power meter to avoid equipment damage caused by excessive temperature. When the parts are removed after the drying operation is completed, the baffle plate 13 can prevent hot air from directly acting on the main body 1, reducing maintenance costs. In addition, the digital power meter can also help technicians quickly identify the fault location when the equipment fails, reducing maintenance time.

[0039] Reference Figure 2 and Figure 5 To further improve the practicality of the device, multiple sets of opposing support frames 14 are detachably installed on both sides of the inner shell 21 along the height direction. A drying tray 15 is detachably installed on the support frame 14. Multiple hanging holes 16 are evenly arranged in the horizontal and vertical directions on both side walls of the inner shell 21 located in the drying space. Hooks 17 that cooperate with the hanging holes 16 are provided on the support frame 14. In this embodiment, the hanging holes 16 on one side wall of the inner shell 21 are evenly arranged in three rows along the vertical direction, the hooks 17 on the support frame 14 are three, and the drying tray 15 is provided with a through hole 18.

[0040] Reference Figure 2 and Figure 5During the drying operation, the staff can adjust the installation position of the support frame 14 according to the height of the parts to be dried. Then, the drying tray 15 carrying the parts to be dried is placed on the support frame 14. Through the cooperation of the heating tube 41 and the hot air circulation mechanism 5, the parts are dried efficiently. In addition, the multiple movable drying trays 15 divide the interior of the drying box 2 into multiple areas, realizing the simultaneous drying of multiple parts to be dried and improving the work efficiency.

[0041] The working process and implementation principle of the high-efficiency hot air circulation drying device in this embodiment are as follows: the cooperation of heating pipe 41 and hot air circulation mechanism 5 ensures uniform circulation of hot air in drying box 2, achieving high-efficiency drying; the drying tray 15 is detachably installed in drying box 2 to meet the simultaneous drying of multiple parts of different specifications; the baffle 13 avoids hot air directly acting on the main body 1, extends the service life of the device, and improves the utilization rate of the device; the temperature controller and digital power meter are set to realize real-time monitoring of temperature, voltage, and current during the drying process, ensuring the smooth completion of the drying operation.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
