Description

Technical Field

[0001] This utility model relates to the field of insulator technology, and in particular to an automatic temperature control and automatic dehumidification drying device for insulator blanks. Background Technology

[0002] An insulator is a special type of insulating control that plays an important role in overhead power transmission lines. Insulators can be classified into porcelain insulators, glass insulators, and composite insulators according to the different insulating materials used. In the production process of porcelain insulators, it is usually necessary to use a drying device to air dry the porcelain insulator clay blanks.

[0003] Existing technologies have the following problems:

[0004] Extensive searches revealed that patent application CN201921917072.7 discloses a drying device for porcelain insulator production. However, this patent has some issues in practical use. The most obvious problem is that the patent uses hot air flowing upwards from the bottom of the drying chamber to dry the insulator blanks. However, the insulator blanks at the bottom of the drying chamber are closer to the air nozzles, while those at the top are farther away. This can easily cause uneven drying of the insulator blanks at the bottom and top of the drying chamber, affecting the quality of the insulators.

[0005] To address these shortcomings, we propose an automatic temperature control and dehumidification drying device for insulator blanks. Utility Model Content

[0006] The purpose of this invention is to provide an automatic temperature control and automatic dehumidification drying device for insulator blanks, which addresses the shortcomings of existing technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an automatic temperature-controlled and automatic dehumidification drying device for insulator blanks, comprising a drying box, a drive motor fixedly installed on the top surface of the drying box, and an adjustment frame installed inside the drying box with the output end of the drive motor extending into the drying box, and a placement plate adjustablely provided on the surface of the adjustment frame; a dehumidification pipe fixedly installed on the top surface of the drying box, and an electromagnetic valve installed on the dehumidification pipe; a temperature sensor fixedly installed on the inner top surface of the drying box; a drying pipe fixedly installed on the inner wall of the drying box, and an air nozzle fixedly installed on the surface of the drying pipe; a fan fixedly installed on the outer wall of the drying box, and an electric heating wire heater installed at the air outlet end of the fan; an air inlet pipe installed at the other end of the electric heating wire heater, and the other end of the air inlet pipe extending into the drying box and connecting to the drying pipe; an adjustment hole opened on the surface of the adjustment frame; a fixing rod provided below the placement plate, and the fixing rod being inserted into the adjustment hole; a fixing plate installed at one end of the fixing rod, and a spring provided between the fixing plate and the placement plate on the outside of the fixing rod.

[0008] Preferably, the surface of the drying oven is hinged with a door, and a microcontroller is fixedly installed on the surface of the door. The microcontroller is electrically connected to a drive motor, a solenoid valve, a temperature sensor, a fan, and a heating wire heater via wires.

[0009] Preferably, the air nozzles are provided in multiple locations, and the multiple air nozzles are equidistantly distributed on the surface of the drying tube.

[0010] Preferably, multiple placement plates are provided, and the multiple placement plates are equidistantly arranged along the length direction of the adjustment frame.

[0011] Preferably, the adjustment holes are provided in multiple locations, and the multiple adjustment holes are equidistantly arranged along the length direction of the adjustment frame.

[0012] Preferably, the diameter of the placement plate is smaller than the diameter of the drying oven.

[0013] Preferably, the aforementioned.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, a rotatable adjustment frame is set up, and a drive motor drives the adjustment frame to rotate, thereby causing the insulators on the placement plate to rotate as well. This makes the insulators more evenly heated by contact with the hot air, avoiding the problem of uneven drying effect caused by the insulator blanks at the bottom of the drying box being closer to the air nozzle and the insulator blanks at the top of the drying box being farther away from the air nozzle. This reduces the impact on the quality of the insulators and improves the drying effect.

[0016] 2. By setting an adjustable placement plate, the spacing between the placement plates can be flexibly adjusted, which is convenient for use with insulators of different specifications, greatly improving the scope of application, making it highly practical and worthy of promotion.

[0026] Please refer to Figure 1-4An automatic temperature-controlled and automatic dehumidification drying device for insulator blanks includes a drying chamber 1. A drive motor 2 is fixedly installed on the top surface of the drying chamber 1, and the output end of the drive motor 2 extends into the interior of the drying chamber 1 where an adjusting frame 3 is installed. A placement plate 4 is adjustablely mounted on the surface of the adjusting frame 3. A dehumidification pipe 10 is fixedly installed on the top surface of the drying chamber 1, and a solenoid valve 11 is installed on the dehumidification pipe 10. A temperature sensor 12 is fixedly installed on the inner top surface of the drying chamber 1. A drying pipe 8 is fixedly installed on the inner wall of the drying chamber 1, and an air filter is fixedly installed on the surface of the drying pipe 8. A fan 5 is fixedly installed on the outer wall of the drying chamber 1, and an electric heating wire heater 6 is installed at the air outlet end of the fan 5. An air inlet pipe 7 is installed at the other end of the electric heating wire heater 6, and the other end of the air inlet pipe 7 extends into the interior of the drying chamber 1 and connects with the drying pipe 8. An adjustment hole 15 is opened on the surface of the adjustment frame 3. A fixing rod 16 is provided below the placement plate 4, and the fixing rod 16 is inserted into the adjustment hole 15. A fixing plate 17 is installed at one end of the fixing rod 16, and a spring 18 is provided between the fixing plate 17 and the placement plate 4 on the outside of the fixing rod 16.

[0027] In this embodiment: the surface of the drying oven 1 is hinged with a door 13, and a microcontroller 14 is fixedly installed on the surface of the door 13. The microcontroller 14 is electrically connected to the drive motor 2, the solenoid valve 11, the temperature sensor 12, the fan 5 and the heating wire heater 6 through wires.

[0028] Specifically, the box door 13 is opened, and several insulator blanks are placed sequentially on multiple placement plates 4. Then, the box door 13 is closed, and the drive motor 2 is started by the microcontroller 14. The drive motor 2 drives the adjusting frame 3 to rotate, thereby causing the insulators on the placement plates 4 to rotate accordingly. Simultaneously, the fan 5 operates, sending air into the electric heating wire heater 6. The electric heating wire heater 6 heats the air and sends it into the drying chamber 1, finally blowing it out from several air nozzles 9. This process evenly dries the rotating insulator blanks, ensuring more uniform heating of the insulators in contact with the hot air and preventing insulation damage. To address the issue of insulators experiencing localized drying inefficiencies, an adjustable placement plate 4 was designed. This allows for flexible adjustment of the spacing between the placement plates, facilitating the use of insulators of different specifications and greatly expanding its applicability. The design of the solenoid valve 11 enables timed opening and closing for automatic dehumidification. Furthermore, when the temperature sensor 12 detects that the temperature inside the drying chamber 1 is outside the preset range, it sends a signal to the microcontroller 14 for analysis and processing, and activates or deactivates the fan 5 and the heating element 6, achieving automatic temperature control and drying.

[0029] In this embodiment, multiple air nozzles 9 are provided, and the multiple air nozzles 9 are equidistantly distributed on the surface of the drying tube 8.

[0030] Specifically, it improves the drying effect and efficiency of insulator blanks, resulting in more uniform heating of the insulator blanks.

[0031] In this embodiment, multiple placement plates 4 are provided, and the multiple placement plates 4 are equidistantly arranged along the length direction of the adjustment frame 3.

[0032] Specifically, it improves the ability to place insulator blanks, enabling the drying of several insulator blanks at once.

[0033] In this embodiment, multiple adjustment holes 15 are provided, and the multiple adjustment holes 15 are equidistantly arranged along the length direction of the adjustment frame 3.

[0034] Specifically, it allows for flexible adjustment of the spacing between two adjacent placement plates 4, making it more widely applicable.

[0035] In this embodiment, the diameter of the placement plate 4 is smaller than the diameter of the drying oven 1.

[0036] Specifically, this allows the placement plate 4 to rotate inside the drying chamber 1.

[0037] In this implementation scheme: the microcontroller 14 is an existing structure, and the control circuit can be implemented by those skilled in the art through simple programming. It is common knowledge in the field, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0038] Working Principle: In use, open the box door 13 and place several insulator blanks sequentially onto multiple placement plates 4. Then close the box door 13 and start the drive motor 2 via the microcontroller 14. The drive motor 2 drives the adjusting frame 3 to rotate, thereby causing the insulators on the placement plates 4 to rotate accordingly. Simultaneously, the fan 5 operates, sending air into the electric heating wire heater 6. The electric heating wire heater 6 heats the air and sends it into the drying chamber 1, finally blowing it out from several air nozzles 9. This ensures uniform drying of the rotating insulator blanks, making the insulators more evenly heated by contact with the hot air, avoiding... To prevent insulators from experiencing localized unsatisfactory drying and improve the drying effect, an adjustable placement plate 4 is incorporated. This allows for flexible adjustment of the spacing between the placement plates 4, facilitating the use of insulators of different specifications and greatly expanding the applicability. Its practicality is strong and worthy of promotion. The design of the solenoid valve 11 enables timed opening and closing, achieving automatic dehumidification. When the temperature sensor 12 detects that the temperature inside the drying chamber 1 is outside the preset temperature range, it sends a signal to the microcontroller 14 for analysis and processing, and starts / stops the fan 5 and the heating wire heater 6, achieving automatic temperature control and drying.

[0039] It should be noted that the model and specifications of the microcontroller 14, the drive motor 2, the solenoid valve 11, the temperature sensor 12, the fan 5, and the electric heating wire heater 6, need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The power supply and operating principle of the microcontroller 14, drive motor 2, solenoid valve 11, temperature sensor 12, fan 5 and heating wire heater 6 are clear to those skilled in the art and will not be described in detail here.

[0041] It is worth noting that the microcontroller 14 disclosed in the above embodiments can be an MCS-51. The microcontroller 14 controls the operation of the drive motor 2, solenoid valve 11, temperature sensor 12, fan 5 and heating wire heater 6 using methods commonly used in the prior art.
