Description

Technical Field

[0001] This utility model belongs to the technical field of metal heat treatment equipment, and in particular relates to a forced convection cooling device for a baking furnace. Background Technology

[0002] An oven is a device used to heat, dry, or bake materials. It has a wide range of applications in various fields. The oven is equipped with heating elements, such as electric heating tubes and burners, which can convert electrical energy or fuel combustion into heat energy. The heat is transferred through conduction and convection, which raises the surface temperature of the material and evaporates the internal moisture or solvent, ultimately achieving the desired degree of dryness.

[0003] After the heating process is completed in the oven, the temperature inside the oven is high. During natural cooling, the high temperature remains for a long time, which may cause the equipment to age or be damaged due to the long-term residual high temperature inside the oven. Therefore, a forced convection cooling device for the oven is needed. A centrifugal fan blows air to accelerate the flow, so that the airflow carries away the heat from the surface of the material. Then, an induced draft fan exhausts the hot air out of the oven, which effectively reduces the occurrence of the equipment aging or damage caused by the long-term residual high temperature inside the oven. Utility Model Content

[0004] The purpose of this invention is to provide a forced convection cooling device for a drying oven, which uses a centrifugal fan to blow air to accelerate its flow, allowing the airflow to carry away the heat from the surface of the material. Subsequently, an induced draft fan discharges the hot air into the drying oven, effectively reducing the aging or damage of the equipment itself caused by the long-term residual high temperature inside the drying oven, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A forced convection cooling device for a baking oven includes a bottom plate disposed on the inner wall of the baking oven, a turntable rotatably connected to the inner wall of the bottom plate, a trolley disposed on the top of the turntable, an annular groove formed at the bottom of the turntable, two symmetrical limiting rods slidably connected to the surface of the annular groove, a connecting block fixedly connected to the bottom of the turntable by bolts, a turbine fixedly connected to the surface of the connecting block, a motor fixedly connected to the inner wall of the baking oven by bolts, a connecting rod fixedly connected to the output shaft of the motor, a worm gear fixedly connected to the surface of the connecting rod, three centrifugal fans installed on the left side of the baking oven, and an induced draft fan installed on the surface of the baking oven.

[0021] Example 1:

[0022] Figure 1-4This invention illustrates a forced convection cooling device for an oven according to an embodiment of the present invention. The device includes: a base plate 2 disposed on the inner wall of the oven 1; a turntable 3 rotatably connected to the inner wall of the base plate 2; a trolley 4 disposed on the top of the turntable 3; an annular groove 5 formed at the bottom of the turntable 3; two symmetrical limiting rods 6 slidably connected to the surface of the annular groove 5; a connecting block 7 bolted to the bottom of the turntable 3; the bottom of the connecting block 7 rotatably connected to the inner wall of the oven 1; a turbine 8 fixedly connected to the surface of the connecting block 7; and the inner wall of the oven 1 bolted together. There is a motor 9, and the output shaft of the motor 9 is fixedly connected to a connecting rod 10. A worm gear 11 is fixedly connected to the surface of the connecting rod 10. The end of the connecting rod 10 is rotatably connected to a limit block 12 through a rotating shaft. The limit block 12 is a rectangular limit block. The setting of the limit block 12 enables the connecting rod 10 to be supported, reducing the wobbling of the connecting rod 10 during rotation and improving the stability of the connecting rod 10 during rotation. Three centrifugal fans 13 are installed on the left side of the oven 1, and an induced draft fan 14 is installed on the surface of the oven 1.

[0023] Example 2:

[0024] Figure 1-4 This invention illustrates a forced convection cooling device for an oven according to an embodiment of the present invention. The device includes: a base plate 2 disposed on the inner wall of the oven 1; a turntable 3 rotatably connected to the inner wall of the base plate 2; a trolley 4 disposed on the top of the turntable 3; an annular groove 5 formed at the bottom of the turntable 3; two symmetrical limiting rods 6 slidably connected to the surface of the annular groove 5; the surfaces of the annular groove 5 and the limiting rods 6 being adapted to each other; the bottom ends of the limiting rods 6 being fixedly connected to the inner wall of the oven 1; a connecting block 7 fixedly connected to the bottom of the turntable 3 by bolts; a turbine 8 fixedly connected to the surface of the connecting block 7; a motor 9 fixedly connected to the inner wall of the oven 1 by bolts; a connecting rod 10 fixedly connected to the output shaft of the motor 9; a worm gear 11 fixedly connected to the surface of the connecting rod 10; the surfaces of the turbine 8 and the worm gear 11 being adapted to each other and meshing; three centrifugal fans 13 installed on the left side of the oven 1; and an induced draft fan 14 installed on the surface of the oven 1.

[0025] Working Principle: When using this invention, the user pushes the trolley 4 to the top of the turntable 3, then starts the centrifugal fan 13, causing the centrifugal fan 13 to blow air and accelerate its flow, thus allowing the airflow to carry away the heat from the surface of the material. At this time, the induced draft fan 14 is started, causing the induced draft fan 14 to discharge the hot air into the oven 1. During this process, the motor 9 is started, causing the motor 9 to drive the worm gear 11 to rotate through the connecting rod 10, which in turn drives the turbine 8 to rotate, which in turn drives the turntable 3 to rotate through the connecting block 7. At this time, with the cooperation of the annular groove 5 and the limiting rod 6, the rotation of the turntable 3 is supported, reducing the occurrence of shaking during the rotation of the turntable 3, effectively improving the stability of the turntable 3 during rotation, and causing the turntable 3 to drive the trolley 4 to rotate, thereby improving the uniformity of cooling of the material placed on the surface of 4, and reducing the occurrence of uneven cooling of the material, effectively reducing the possibility of the high temperature remaining in the oven for a long time accelerating the aging or damage of the equipment itself.

[0026] In summary, the forced convection cooling device of this oven accelerates the airflow by blowing air through the centrifugal fan 13, which causes the airflow to carry away the heat from the surface of the material. At this time, by starting the induced draft fan 14, the hot air is discharged from the oven 1, which can effectively reduce the aging or damage of the equipment itself caused by the long-term residual high temperature in the oven.
