[0002] Industrial microwave ovens are widely used in food processing, chemical industry, pharmaceutical industry and many other fields. Their working principle is to use the high-frequency electromagnetic field of microwaves to cause the polar molecules in the material to generate high-frequency polarization and violent movement, thereby generating heat and realizing the functions of heating, drying and sterilizing the material. The microwave cavity contains an industrial conveyor line (such as belt, chain plate and other conveyor lines).

[0003] In existing technologies, microwave energy leakage during microwave oven operation can not only pose potential health hazards to operators, such as causing electromagnetic radiation-related diseases, but also lead to energy waste and reduced heating efficiency of the equipment.

[0004] Therefore, this utility model provides a sealing mechanism for an industrial microwave oven. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 4 As shown in the figure, a sealing mechanism for an industrial microwave oven according to an embodiment of the present invention includes a furnace body 1, on which a sealing mechanism is provided. The sealing mechanism includes: a sealing component, including a pair of fixing blocks 2 fixedly connected to both sides of the furnace body 1, a sealing plate 3 rotatably connected between the opposite side walls of the pair of fixing blocks 2 via a rotating rod, a protective plate 4 fixedly connected to the side of the sealing plate 3 near the furnace body 1, a U-shaped frame 5 fixedly connected to the end of the furnace body 1 near the sealing plate 3, a U-shaped groove 6 opened on the inner wall of the U-shaped frame 5, and an elastic sealing gasket 7 provided in the U-shaped groove 6; a driving component, set on the top of the furnace body 1 for driving the sealing plate 3 to rotate; and a locking component, set on the furnace body 1 for fixing the sealing plate.

[0026] During operation, the protective plate 4 is fixed to the side of the sealing plate 3 near the oven body 1, which further enhances the structural strength of the sealing plate 3 and prevents deformation under high temperature and microwave environment. The elastic sealing gasket 7 ensures reliable sealing. This solves the problem in the prior art that microwave energy leakage during the operation of microwave ovens not only poses potential health hazards to operators, such as causing electromagnetic radiation-related diseases, but also may lead to energy waste and reduce the heating efficiency of the equipment.

[0027] The drive assembly includes an electric push rod 8 fixed to the top of the furnace body 1 via a support block, a connecting block 9 fixed to the telescopic end of the electric push rod 8, a pair of rectangular blocks 10 fixed to the top of the sealing plate 3, and the connecting block 9 rotatably connected between the opposite side walls of the pair of rectangular blocks 10 via a first rotating shaft.

[0028] During operation, the connecting block 9 can be driven by the electric actuator 8 to rotate the top of the sealing plate 3 around the rotating rod as the central axis, thus completing the sealing.

[0029] The positioning assembly includes positioning blocks 11 fixedly attached to both sides of the furnace body 1, with arc-shaped through grooves 12 on the positioning blocks. Arc-shaped blocks 13 are fixedly attached to both sides of the sealing plate 3. A positioning groove 14 is opened on the top of the arc-shaped blocks 13. A positioning through groove 15 is opened on the top of the positioning blocks 11. A concave block 16 is fixedly attached to the top of the positioning blocks 11. A pressure rod 17 is slidably connected to the concave block 16 through a through hole. A positioning block 18 is fixedly attached to the bottom of the pressure rod 17, and the positioning block 18 is connected to the bottom of the concave block 16 laterally through a spring 19.

[0030] A square rod 20 is slidably connected to the positioning block 11 through a square hole. An isosceles block 21 is fixed to the top of the square rod 20. The bottom of the isosceles block 21 away from the square rod 20 is fixed to the top of the pressing rod 17. A support bar 22 is fixed to the bottom of a pair of square rods 20.

[0031] During operation, the positioning block 11 has an arc-shaped through groove 12. When the arc-shaped block 13 closes with the sealing plate 3, the arc-shaped block 13 can be stuck in the arc-shaped through groove 12. The arc-shaped surface on the arc-shaped block 13 can press against the locking block 18, so that after the arc-shaped block 13 is completely in contact with the arc-shaped through groove 12, it can be locked into the locking groove 14. This solves the problem that the sealing furnace door mechanism of traditional industrial furnaces is mostly locked manually, which is difficult to lock automatically. This can easily lead to the sealing furnace door mechanism of industrial furnaces not being locked, which can cause accidents. When it is necessary to open, simply push the support bar 22 upward.

[0032] The elastic sealing gasket 7 is made of polytetrafluoroethylene.

[0033] During operation, PTFE has extremely high heat resistance and can maintain stable performance over a wide temperature range. In the high-temperature environment of industrial microwave ovens, PTFE gaskets can maintain good sealing performance and will not deform or age due to high temperatures, ensuring long-term stable operation of the equipment.

[0034] Protective plate 4 is made of stainless steel.

[0035] During operation, the stainless steel protective plate 4 maintains good mechanical properties in high-temperature environments, is not easily deformed, has good corrosion resistance, and can resist the erosion of chemical substances inside the microwave oven.

[0036] Working principle: The protective plate 4 is fixed to the side of the sealing plate 3 near the oven body 1, which further enhances the structural strength of the sealing plate 3 and prevents deformation under high temperature and microwave environment. The elastic sealing gasket 7 ensures reliable sealing. This solves the problem in the prior art that microwave energy leakage during the operation of microwave ovens not only poses potential health hazards to the operator, such as causing electromagnetic radiation-related diseases, but also may lead to energy waste and reduce the heating efficiency of the equipment.

[0037] Driven by the electric actuator 8, the connecting block 9 can push the top of the sealing plate 3 to rotate around the rotating rod as the central axis, thus completing the sealing.

[0038] The positioning block 11 has an arc-shaped through groove 12. When the arc-shaped block 13 is closed with the sealing plate 3, the arc-shaped block 13 can be stuck in the arc-shaped through groove 12. The arc-shaped surface on the arc-shaped block 13 can press against the locking block 18, so that after the arc-shaped block 13 is completely in contact with the arc-shaped through groove 12, it can be locked into the locking groove 14. This solves the problem that the sealing furnace door mechanism of traditional industrial furnaces is mostly locked manually, which is difficult to lock automatically. This can easily lead to the sealing furnace door mechanism of industrial furnaces not being locked, which can cause accidents. When it is necessary to open, simply push the support bar 22 upward.

[0039] Polytetrafluoroethylene (PTFE) has extremely high heat resistance and can maintain stable performance over a wide temperature range. In the high-temperature environment of industrial microwave ovens, PTFE gaskets can maintain good sealing performance and will not deform or age due to high temperatures, ensuring the long-term stable operation of the equipment.

[0040] The stainless steel protective plate 4 can maintain good mechanical properties in high-temperature environments, is not easily deformed, has good corrosion resistance, and can resist the erosion of chemical substances inside the microwave oven.
