Description

Technical Field

[0001] This utility model relates to the field of electric heating furnace technology, and more specifically, to an electric heating furnace body for uniform temperature distribution in the furnace cavity. Background Technology

[0002] Electric heating furnaces are a new type of safe, efficient, and energy-saving equipment. They are special industrial furnaces that can provide high-temperature heat energy. They use heat transfer oil as the heat carrier and circulate the heat carrier through a hot oil pump to transfer heat to the heat-using equipment. They can be used to heat and dry materials, process chemical materials, and provide heating for equipment, thus meeting the requirements of industrial production.

[0003] Currently, there are many types of electric heating furnaces, and their quality and size vary, making it difficult for users to purchase a suitable electric heating furnace. Moreover, ordinary electric heating furnaces have problems such as small heating range and inconvenient heating, which will reduce production efficiency and fail to meet the requirements of production and processing. Therefore, we propose an electric heating furnace.

[0004] A search revealed that Chinese patent CN207881225U discloses an electric heating furnace. By placing the object to be heated in a heat-conducting box, the heat-conducting oil in the heating box heats the object. It is easy to use and suitable for heating various types of materials. By placing the object on fixed plates at different heights, the heating degree can be controlled. The outlets of the upper and lower oil distribution pipes can be connected to heat-conducting devices. The heat-conducting oil enters the corresponding heat-conducting devices from the two oil distribution pipes, enabling long-distance heating, which is beneficial for industrial production and processing.

[0005] In actual use, the objects in the aforementioned electric heating furnace need to maintain a certain position and state to ensure the heat treatment effect. However, during the heating process, the objects may undergo slight deformation or displacement, resulting in uneven heat treatment. At the same time, the objects may collide with the furnace wall or other objects, causing damage. Utility Model Content

[0010] By adopting the above technical solution, pressure is applied to the top of the object through the connecting rod and the fixing block, thereby ensuring the stability of the position of the object to be heated in the furnace.

[0011] As a further description of the above technical solution: Refractory bricks are installed inside the electric heating furnace body.

[0012] By adopting the above technical solution, the first protective box, the second protective box and the third protective box can be used to heat different areas inside the electric heating furnace body under different conditions, thereby ensuring that the electric heating furnace body can maintain a uniform temperature.

A sliding rod 9 is slidably connected to one side of the double-sided rack 5 and the fixing plate 7. The sliding rod 9 is fixedly connected to the inside of the fixing box 2. A connecting rod 10 is fixedly connected to the top end of the double-sided rack 5. The connecting rod 10 is connected to the fixing box 2.

[0026] Reference Figure 1 and 2As shown, the electric heating furnace body 1 is equipped with refractory bricks 13 inside. A temperature equalization mechanism is installed on one side of the refractory bricks 13. The temperature equalization mechanism includes a first protective box 14, which is fixedly connected to one side of the refractory bricks 13. Multiple first electric heating wires 15 are installed inside the first protective box 14. A heat-conducting plate 16 is provided on one side of the first electric heating wire 15 and is fixedly connected to the inside of the first protective box 14. A second protective box 17 is fixedly connected to one side of the refractory bricks 13. Two second electric heating wires 18 are installed inside the second protective box 17. A third protective box 19 is fixedly connected to one side of the refractory bricks 13. A fan 20 is installed inside the third protective box 19. Multiple third electric heating wires 21 are provided on one side of the fan 20. A grate 22 is installed inside the electric heating furnace body 1. Multiple blowers 23 are installed on the outside of the electric heating furnace body 1. The output end of the blower 23 passes through the refractory bricks 13 and communicates with the first protective box 14. A baffle 24 is fixedly connected inside the electric heating furnace body 1. 10 is slidably connected to the inner side of the baffle 24. Multiple dense first electric heating wires 15 are used to heat the bottom inner side of the electric heating furnace body 1. The heat can be blown into the electric heating furnace body 1 by the blower 23. The heat conduction plate 16 can quickly dissipate the heat into the electric heating furnace body 1, so that the bottom inner side of the electric heating furnace body 1 can be heated. The "U"-shaped second electric heating wire 18 can dissipate heat in the middle inner side of the electric heating furnace body 1, so that the middle inner side of the electric heating furnace body 1 can be heated. The sparse third electric heating wire 21 can heat the top inner side of the electric heating furnace body 1. At the same time, the two fans 20 can conduct convection, so that the heat accumulated at the top of the electric heating furnace body 1 can be blown away. The slope on the outer side of the baffle 24 can guide the flow, so that the heat blown by the fans 20 can flow downward, realizing heat circulation. This allows the heat inside the electric heating furnace body 1 to be heated evenly, maintaining the uniform temperature inside the electric heating furnace body 1.

[0027] Working principle of this utility model: This utility model is designed with an electric heating furnace body that ensures uniform temperature throughout the furnace cavity. The specific structure is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation of various structures, when it is necessary to heat an object, the stepper motor 3 is first started, and the stepper motor 3 drives the first gear 4 to rotate, so that the first gear 4 can mesh and drive the double-sided rack 5 to move. The double-sided rack 5 can then pull the two first springs 8 through the fixed plate 7. Simultaneously, the second gear 6 provides stability for the movement of the double-sided rack 5, and the slide rod 9 provides guidance for the movement of the double-sided rack 5 and the fixed plate 7, allowing the double-sided rack 5 to drive the connecting rod 10 to move to the inside of the baffle 24. The object is then placed into the electric heating furnace body 1, and the stepper motor 3 is driven to rotate in the opposite direction, so that the double-sided rack 5 can drive the connecting rod 10 to move downward to the upper surface of the object. The two second springs 11 can extend and retract inside the connecting rod 10, so that the fixing block 12 can better fit the shape of the top of the object. The return force of the two first springs 8, together with the first gear 4 and the second gear 6, can limit the position of the double-sided rack 5, so that the fixing block 12 applies pressure to the top, thereby limiting and fixing the object inside the electric heating furnace body 1. Then the grate 22 is started. This allows for the heating of objects. Simultaneously, the first heating wire 15, the second heating wire 18, and the third heating wire 21 are activated. Multiple densely packed first heating wires 15 heat the inner bottom of the electric heating furnace body 1. The heat-conducting plate 16 rapidly dissipates the heat generated by the first heating wires 15 to the outside. Multiple blowers 23 blow the heat generated by the first heating wires 15 into the interior of the electric heating furnace body 1, thereby increasing the temperature at the bottom of the electric heating furnace body 1. Two second heating wires 18 generate heat in the middle of the electric heating furnace body 1. It can provide heating to the middle part of the electric heating furnace body 1. Heat is generated at the top inner side of the electric heating furnace body 1 through the sparse third electric heating wire 21. At the same time, the two fans 20 can blow the heat at the top inner side of the electric heating furnace body 1 and generate convection. The slope on the outside of the baffle 24 provides airflow guidance, so that the heat inside the electric heating furnace body 1 can be circulated from top to bottom. It works in conjunction with the first electric heating wire 15, the second electric heating wire 18 and the third electric heating wire 21 to ensure that the heat can be evenly distributed to all corners of the furnace, so that the furnace cavity is heated evenly.
