Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic detonator processing technology, specifically to a drying device for electronic detonator processing. Background Technology
[0002] Electronic detonators, also known as digital electronic detonators, digital detonators, or industrial digital electronic detonators, are electric detonators that use electronic control modules to control the detonation process. During the manufacturing process of electronic detonators, after the ignition head is coated with the explosive, it needs to be dried in a drying oven to remove moisture and humidity, ensuring the stability and reliability of the ignition head.
[0003] Traditionally, the ignition heads are placed directly in the drying chamber for drying. However, because the ignition heads are tangled and piled up together, the hot air cannot be evenly distributed to each ignition head during drying, which easily leads to uneven drying. Moreover, due to the special nature of electronic detonators, temperature and pressure must be strictly controlled during the drying process. Therefore, it is particularly important to develop an electronic detonator drying device that can achieve uniform drying while ensuring safety. Utility Model Content
[0004] The technical problem this invention aims to solve is that the ignition heads are tangled and piled up together. Traditional drying devices cannot blow hot air evenly onto each ignition head, which easily leads to uneven drying and affects product quality. Moreover, the drying process of electronic detonators requires strict control of temperature and pressure, as excessive pressure can easily cause expansion or even explosion.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a drying device for processing electronic detonators, including a drying box, a sealed door on one side of the drying box, a motor on one side of the drying box, a drying shaft driven by the motor and easily disassembled inside the drying box, a circular fixing frame on the drying shaft, at least one arc-shaped winding frame on one side of the circular fixing frame, a heating and drying structure at the bottom of the drying box, a temperature sensor and a pressure sensor respectively at the top of the drying box, a controller electrically connected to the temperature sensor and the pressure sensor at the top of the drying box, and a pressure-reducing door connected to the controller at the top of the drying box.
[0006] As an improvement, the drying box is provided with rotating shafts inserted into both sides, and an arc-shaped plate is provided on one side of each rotating shaft. Both ends of the drying shaft rest on the arc-shaped plate, and the arc-shaped plate and the drying shaft are locked and fixed together by locking bolts and locking nuts.
[0007] As an improvement, a second gear is provided at one end of the rotating shaft extending outside the drying chamber, and a first gear that meshes with the second gear is provided at the output end of the motor. The motor is mounted on the side wall of the drying chamber via an L-shaped plate.
[0008] As an improvement, the heating and drying structure includes a warm air blower located on one side of the drying chamber, and multiple air ducts connected to the warm air blower are provided at the bottom of the drying chamber, with multiple evenly distributed air outlets on the air ducts.
[0009] As an improvement, the sealed door is provided with a viewing window, and a control panel is provided on one side of the sealed door.
[0010] The advantages of this utility model compared with the prior art are as follows:
[0011] 1. The ignition head of the electronic detonator can be directly wound onto the arc-shaped winding frame using the arc-shaped winding frame and the circular fixing frame. With the cooperation of the motor, rotating shaft, first gear, second gear, arc plate, locking bolt and locking nut, the drying shaft is driven to rotate, so that the ignition head can rotate evenly inside the drying chamber, and the heat is uniform, ensuring thorough drying.
[0012] 2. Temperature and pressure sensors can monitor the temperature and pressure inside the drying oven in real time and transmit the data to the controller. When the temperature or pressure exceeds the set value, the controller directly controls the pressure relief door to open, releasing the internal pressure and ensuring the safety of the drying process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example 1
[0021] Combined with appendix Figure 1 A drying device for processing electronic detonators includes a drying chamber 1, a sealed door 2 on one side of the drying chamber 1, a viewing window 3 on the sealed door 2, and a control panel 4 on one side of the sealed door 2.
[0022] With the above structure, the internal drying status can be viewed in real time using the viewing window 3, and the control panel 4 makes it easy to control the operating device and use.
[0023] Combined with appendix Figure 3 and attached Figure 5 The drying box 1 is equipped with a motor 5 on one side, and a drying shaft 6 driven by the motor 5 and easy to disassemble is provided inside the drying box 1. A circular fixing frame 7 is provided on the drying shaft 6, and at least one arc-shaped winding frame 8 is provided on one side of the circular fixing frame 7.
[0024] With the above structure, the ignition head of the electronic detonator can be directly wound onto the arc-shaped winding frame 8, and both ends of the ignition head can be fixed onto the arc-shaped winding frame 8 with clamps. As the drying shaft 6 rotates, the arc-shaped winding frame 8 rotates accordingly, and the ignition head of the electronic detonator can be directly dried.
[0025] Combined with appendix Figure 2 Appendix Figure 3 and attached Figure 6The drying chamber 1 has rotating shafts 9 inserted into both sides. Each side of the rotating shaft 9 has an arc-shaped plate 10. Both ends of the drying shaft 6 rest on the arc-shaped plate 10. The arc-shaped plate 10 and the drying shaft 6 are locked together by locking bolts and locking nuts. One end of the rotating shaft 9 extending outside the drying chamber 1 has a second gear 12. The output end of the motor 5 has a first gear 11 that meshes with the second gear 12. The motor 5 is mounted on the side wall of the drying chamber 1 by an L-shaped plate.
[0026] With the above structure, the motor 5 drives the first gear 11 to rotate, and the second gear 12, which meshes with the first gear 11, rotates accordingly, thereby driving the rotating shaft 9 on one side to rotate. Since the drying shaft 6 is fixed on the rotating shaft 9 with locking bolts and locking nuts, the drying shaft 6 rotates accordingly, and the circular fixing frame 7 and the arc-shaped winding frame 8 rotate continuously, which facilitates the drying operation. Example 2
[0027] Combined with appendix Figure 3 The drying chamber 1 is equipped with a heating and drying structure at the bottom. The heating and drying structure includes a warm air blower 17 located on one side of the drying chamber 1. The bottom of the drying chamber 1 is equipped with multiple air ducts 18, all of which are connected to the warm air blower 17. The air ducts 18 are equipped with multiple evenly distributed air outlets 19.
[0028] With the above structure, the heater 17 can continuously send hot air into the drying chamber 1 through the air duct and air outlet 19. Since the hot air is lighter, it rises continuously to carry out the drying operation.
[0029] Combined with appendix Figure 3 and attached Figure 4 The top of the drying oven 1 is equipped with a temperature sensor 13 and a pressure sensor 14, respectively. The top of the drying oven 1 is equipped with a controller 15 that is electrically connected to the temperature sensor 13 and the pressure sensor 14. The top of the drying oven 1 is equipped with a pressure reducing door 16 that is connected to the controller 15.
[0030] With the above structure, the temperature sensor 13 and the pressure sensor 14 can monitor the temperature and pressure inside the drying oven 1 in real time and transmit the data signals to the controller 15. According to the set threshold, the controller 15 controls the opening and closing of the pressure relief door 16.
[0031] In specific implementation of this utility model:
[0032] Open the sealed door 2, and directly wrap the ignition head of the electronic detonator around the arc-shaped winding frame 8, and use clamps to fix both ends of the ignition head onto the arc-shaped winding frame 8.
[0033] When the motor 5 is started, the motor 5 drives the first gear 11 to rotate, and the second gear 12, which meshes with the first gear 11, rotates accordingly, thereby driving the rotating shaft 9 on one side to rotate. Since the drying shaft 6 is fixed on the rotating shaft 9 by locking bolts and locking nuts, the drying shaft 6 rotates accordingly, and the circular fixing frame 7 and the arc-shaped winding frame 8 rotate continuously.
[0034] Turn on the heater 17. The heater 17 can continuously send hot air into the drying chamber 1 through the air duct and the air outlet 19. Since the hot air is lighter, it rises directly and performs the drying operation. As the arc-shaped winding frame 8 rotates continuously, it can rotate evenly inside the drying chamber 1, so that the heat is even and the drying is thorough.
[0035] Temperature sensor 13 and pressure sensor 14 at the top of the drying oven 1 can monitor the temperature and pressure inside the drying oven 1 in real time and transmit the data signals to controller 15. According to the set threshold, controller 15 controls the opening and closing of pressure relief door 16. When the temperature and pressure inside the drying oven 1 are high, controller 15 controls pressure relief door 16 to open, reducing internal pressure and temperature, thus ensuring the safety of the drying process.
