Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically to an energy-saving and consumption-reducing PB oven. Background Technology

[0002] In industrial production, many products require drying of their surface coatings during processing, and the PB oven is a key piece of equipment specifically designed for this step. By providing a stable high-temperature environment, it promotes rapid curing of the coating on the product surface, thereby ensuring the coating's adhesion, wear resistance, and aesthetics. It is widely used in the post-coating processing of various industrial products such as automotive parts, appliance casings, and metal products.

[0003] However, in actual operation, existing PB ovens need to operate at high power continuously to heat the internal air in order to meet the specific temperature requirements for coating drying (usually maintained at 80-200℃). Their heating systems mostly use traditional resistance wires or ordinary heating tubes, which have low heat conversion efficiency. A large amount of electrical energy is converted into ineffective heat energy and lost, resulting in high energy consumption per unit product. In addition, some heat will flow out from the inlet and outlet of the PB oven, and the hot air flow in the heating chamber is uneven. Some areas are too hot while others are not hot enough. In order to ensure that the coatings of all products can be dried to the required standard, the drying time often needs to be extended, which indirectly increases energy consumption. Therefore, we propose an energy-saving and consumption-reducing PB oven. Utility Model Content

[0004] In view of the problems existing in the current energy-saving and consumption-reducing PB oven, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an energy-saving and consumption-reducing PB oven, which solves the problem that existing PB ovens, in actual operation, need to continuously operate at high power to heat the internal air in order to meet the specific temperature requirements for coating drying (usually needing to be maintained at 80-200℃). However, their heating systems mostly use traditional resistance wires or ordinary heating tubes, which have low heat conversion efficiency. A large amount of electrical energy is converted into ineffective heat energy and lost, resulting in high energy consumption per unit product. In addition, some heat will flow out from the inlet and outlet of the PB oven, and the hot air flow in the heating chamber is uneven. The temperature in some areas is too high and the temperature in other areas is insufficient. In order to ensure that the coatings of all products can be dried to the required standard, it is often necessary to extend the drying time, which indirectly increases the energy consumption problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An energy-saving and consumption-reducing PB oven includes an oven body, a heat recovery box, and a controller. Multiple support columns are fixedly installed at both ends of the bottom of the oven body, and a fixing block is fixedly installed on the top of each support column. Support rollers are rotatably connected between two opposing fixing blocks. An inlet and an outlet are respectively provided through both sides of the oven body. A conveyor belt runs through the inlet and outlet, with the bottom of the conveyor belt in close contact with the surfaces of the multiple support rollers. Multiple heating tubes are fixedly installed between the top and bottom ends of the oven body, and the surfaces of the multiple heating tubes are coated with an infrared radiation coating. A heat recovery box is fixedly installed on the top of the oven body.

[0007] Preferably, a finned heat exchanger is fixedly installed inside the heat recovery box, and a first guide frame is fixedly installed on both sides inside the oven body. A conveying pipe is fixedly installed on the top of each of the two first guide frames, and the other ends of the two conveying pipes pass through both sides of the heat recovery box and are fixedly connected to both ends of the finned heat exchanger.

[0008] Preferably, a bidirectional lead screw and a slide rod are respectively provided on both sides of one end of the oven body, and the bidirectional lead screw is rotatably connected to one end of the oven body. Mounting blocks are provided on the surfaces of both the bidirectional lead screw and the slide rod, and the mounting frame located on the surface of the bidirectional lead screw is threadedly connected to the bidirectional lead screw. Fixing posts are fixedly installed at the bottom of the multiple mounting blocks, and a second guide frame is fixedly installed at the bottom of the two fixing posts on one side.

[0009] Preferably, a telescopic pipe is fixedly installed on the top of each of the two second guide frames, and both telescopic pipes extend into the interior of the heat recovery box. An air inlet pipe is provided through the top of the heat recovery box, and a first fan is fixedly installed on the surface of the air inlet pipe. A second fan is fixedly installed on the surface of each of the two conveying pipes.

[0010] Preferably, the oven body has a vacuum layer inside, a temperature sensor is fixedly installed inside the oven body, a motor is fixedly installed at one end of the oven body, and the output end of the motor is fixedly connected to one end of a bidirectional lead screw.

[0011] Preferably, a controller is fixedly installed on the surface of the heat recovery box, and an operation panel is fixedly installed on the surface of the controller. The controller is electrically connected to the operation panel, the controller, the first fan, the second fan, the motor, the heating tube, and the temperature sensor.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention improves heat conversion efficiency and reduces ineffective energy loss through an infrared radiation coating on the heating tube surface. The finned heat exchanger inside the heat recovery box recovers heat from the hot air inside the oven, preheating the air before reintroducing it, thus improving energy utilization. The vacuum layer of the oven body effectively prevents heat loss through conduction, while a reasonable airflow structure reduces heat loss at the inlet and outlet, significantly reducing energy consumption per unit product. Furthermore, adjusting the position of the second airflow frame via a motor allows for more even airflow inside the oven, preventing overheating or underheating in certain areas and ensuring uniform drying of all product coatings without extending drying time, thereby improving drying efficiency and product quality stability.

It is simple and convenient to operate, and can accurately adjust parameters according to the drying requirements of different products, thereby improving the applicability and ease of operation of the equipment.

[0018] This utility model discloses an energy-saving and consumption-reducing PB oven.

[0019] This utility model provides, for example Figure 1-4 The illustrated energy-saving and consumption-reducing PB oven includes an oven body 1, a heat recovery box 2, and a controller 3. Multiple support columns 4 are fixedly installed at both ends of the bottom of the oven body 1. A fixing block 5 is fixedly installed on the top of each of the support columns 4. Support rollers 6 are rotatably connected between two opposing fixing blocks 5. An inlet 7 and an outlet 8 are respectively provided through both sides of the oven body 1. A conveyor belt 9 passes through the inlet 7 and the outlet 8, and the bottom of the conveyor belt 9 is in close contact with the surfaces of the multiple support rollers 6. Multiple heating tubes 10 are fixedly installed between the top and bottom ends of the oven body 1. The surfaces of the multiple heating tubes 10 are coated with an infrared radiation coating 11. The heat recovery box 2 is fixedly installed on the top of the oven body 1, which can convert electrical energy into infrared radiation energy, directly radiating it onto the food, accelerating the baking speed, and reducing the ineffective heat loss within the oven.

[0020] This utility model discloses an energy-saving and consumption-reducing PB oven. The heat recovery box 2 is fixedly installed with a finned heat exchanger 12. The oven body 1 has two fixedly installed first guide frames 13 on both sides. The top of the two first guide frames 13 is fixedly installed with conveying pipes 14. The other ends of the two conveying pipes 14 pass through the two sides of the heat recovery box 2 and are fixedly connected to the two ends of the finned heat exchanger 12, thereby increasing the heat exchange area.

[0021] This utility model discloses an energy-saving and consumption-reducing PB oven. The oven body 1 has a bidirectional lead screw 15 and a slide bar 16 on both sides of one end. The bidirectional lead screw 15 is rotatably connected to one end of the oven body 1. Mounting blocks 17 are provided on the surfaces of both the bidirectional lead screw 15 and the slide bar 16. A mounting frame on the surface of the bidirectional lead screw 15 is threadedly connected to the bidirectional lead screw 15. Fixing posts 18 are fixedly installed at the bottom of multiple mounting blocks 17. Second guide frames 19 are fixedly installed at the bottom of two fixing posts 18 on one side. Telescopic tubes 20 are fixedly installed at the top of the two second guide frames 19. Both telescopic tubes 20 extend into the heat recovery box 2. An air inlet pipe 21 penetrates the top of the heat recovery box 2. A first fan 22 is fixedly installed on the surface of the air inlet pipe 21. Second fans 23 are fixedly installed on the surfaces of the two conveying pipes 14. This design allows hot air to flow more evenly inside the oven, preventing some areas from being too hot or too cold.

[0022] This utility model discloses an energy-saving and consumption-reducing PB oven. The oven body 1 has a vacuum layer 24 inside. A temperature sensor 25 is fixedly installed inside the oven body 1. A motor 26 is fixedly installed at one end of the oven body 1. The output end of the motor 26 is fixedly connected to one end of a bidirectional lead screw 15, which effectively reduces the heat loss to the surrounding environment through the outer shell.

[0023] This utility model discloses an energy-saving and consumption-reducing PB oven. A controller 3 is fixedly installed on the surface of the heat recovery box 2, and an operation panel 27 is fixedly installed on the surface of the controller 3. The controller 3 is electrically connected to the operation panel 27, the controller 3, the first fan 22, the second fan 23, the motor 26, the heating tube 10, and the temperature sensor 25. It automatically adjusts the power of the heating element to keep the temperature in the heating cavity within a stable range, thus avoiding energy waste caused by excessive temperature fluctuations.

[0024] When this energy-saving and consumption-reducing PB oven is in operation, the controller 3 first presets the required drying temperature and other parameters. The motor 26 starts, driving the bidirectional lead screw 15 to rotate. Since the mounting block 17 located on the surface of the bidirectional lead screw 15 is threadedly connected to the bidirectional lead screw 15, under the limiting action of the slide rod 16, the mounting block 17 will drive the fixed column 18 and the second guide frame 19 at the bottom to move, thereby adjusting the position of the second guide frame 19 according to the size of the product and the drying requirements. After the adjustment is completed, the product whose coating needs to be dried is placed on the conveyor belt 9. The conveyor belt 9 runs under the support of the support roller 6, sending the product into the oven body 1 from the feed port 7. At this time, the heating tube 10 starts to work. The infrared radiation coating 11 on its surface can efficiently convert electrical energy into infrared radiation energy, which directly acts on the coating on the surface of the product to heat and dry it. During the drying process, the temperature sensor 25 monitors the interior of the oven body 1 in real time. The temperature is measured and the temperature signal is transmitted to the controller 3. The controller 3 automatically adjusts the power of the heating tube 10 according to the preset temperature and the actual temperature to ensure that the internal temperature of the oven is stable within a suitable range. At the same time, the second fan 23 starts and sends the hot air from both sides of the oven body 1 into the finned heat exchanger 12 in the heat recovery box 2 through the first guide frame 13 and the conveying pipe 14. The first fan 22 starts and draws the external cold air into the heat recovery box 2 through the air inlet pipe 21. When the cold air flows through the finned heat exchanger 12, it exchanges heat with the hot air. The preheated cold air is sent back into the oven body 1 through the telescopic pipe 20 and the second guide frame 19 to realize the recycling of heat. The vacuum layer 24 of the oven body 1 can effectively reduce the heat loss to the outside through the box. The airflow at the feed inlet 7 and the discharge outlet 8 is reduced by the structure of the guide frame, etc.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
