Embodiment Construction

[0023] Such as Figure 1-Figure 2 As shown, the natural gas heat treatment furnace includes a furnace body 1, a furnace door 3 is provided on the front side of the furnace body 1, a horizontal guide rail 2 is provided at the bottom of the furnace body 1, the horizontal guide rail 2 extends to the outside of the furnace body, and a trolley is provided on the guide rail 2 4. Lay refractory parts on the trolley 4; evenly arrange 3 flue openings 8 on the side wall of the bottom of the furnace body 1; change the existing flue openings at the back (relative to the furnace door) to the bottom of the furnace and evenly Three flue openings are provided, which overcomes the defect of partial overheating of the side flue openings.

[0024] An air displacer 9 is installed in the flue at the bottom of the furnace body 1, and the air inlet pipe 13 of the air displacer 9 is for cold air to enter. The air displacer 9 uses the waste heat of the flue to preheat the cold air to form hot air. The ai...

Abstract

The invention discloses a natural gas heat treatment furnace, comprising a furnace body, a furnace door is arranged on the front side of the furnace body, a horizontal guide rail is arranged at the bottom of the furnace body, the horizontal guide rail extends to the outside of the furnace body, and a horizontal guide rail is arranged on the horizontal guide rail. There is a trolley on which refractory parts are laid; a number of flue ports are evenly arranged on the side wall of the bottom of the furnace body; an air displacer is arranged in the flue at the bottom of the furnace body, and the air displacer's air intake pipeline When the cold air enters, the air displacer uses the residual heat of the flue to preheat the cold air to form hot air and is discharged from the outlet pipe of the air displacer. The outlet pipe of the air displacer is connected to the burner on the side of the furnace body. In the present invention, burners are arranged on the left and right sides, which overcomes the defects of less burners and uneven heating, and the unsafe and high energy consumption of each flow rate is too large; the air displacer is added, and the waste heat of the flue can be used to preheat the air; natural gas and The hot air is mixed by proportional valve, which is more automatic and more efficient than manual adjustment.

Description

Technical field [0001] The invention relates to a natural gas heat treatment furnace. Background technique [0002] The heat treatment furnace occupies an extremely important position in the heat treatment process of the machinery manufacturing industry. It is an essential equipment to ensure product quality, improve machine efficiency, and extend machine life. [0003] Modern heat treatment (especially chemical heat treatment) processes are becoming more and more complex, and there are many forms of heat treatment furnaces. For the continuous heat treatment process, a suitable continuous heat treatment furnace must be equipped; for the periodic heat treatment process, a forced circulation control atmosphere and the operation of the furnace must be mechanized and automated. In the rapid development of machinery manufacturing and equipment manufacturing, improving the thermal efficiency of heat treatment furnaces, reducing energy consumption, environmental protection, and improving...
