Heating furnace

[0014] As shown in Figure 1, a heating furnace of the present invention includes a charging boat 15 placed in the furnace cavity 11, a furnace body 12, a propulsion device, a sewage mechanism, a grading cooling device, a dual-channel air supply device, and a feed The front end of the furnace body 12 is provided with a feed door 8 and the end is provided with a discharge door 20. The propulsion device includes a clutch device, a threaded push rod 5 and a push rod 6, and the clutch device It includes a gear a2, a gear b3, a gear c4 and a motor 1. The staged cooling device includes a primary cooling box 17 and a secondary cooling box 18. The dual air supply equipment includes an air supply source 13, a backup air supply source 14, A gas flow meter 29 and a backup gas flow meter 31. The motor 1 is connected to the gear a2, the gear b3 is connected to the gear a2, the gear c4 is connected to the gear b3, and the gear c4 is connected to a threaded push rod through internal tooth patterns. 5 connection, the push rod 6 is connected with the threaded push rod 5, and the axis is on the same horizontal line, the push rod is connected with the loading boat 15 placed in the furnace cavity 11, the upper part of the feed door 8 An exhaust pipe 10 is provided, the lower part of the feed gate 8 is provided with a sewage mechanism 21, the middle part of the exhaust pipe 10 is provided with a throttle valve 9, the middle part of the sewage mechanism 21 is provided with a filter screen 16, and the lower part is provided with a shut-off valve 33. A first-level cooling box 17 and a second-level cooling box 18 are sequentially arranged at the end of the furnace body 12 near the discharge door 20. The first-level water inlet pipe 30 is connected to the lower end of the first-level cooling box 17, and the second The water inlet pipe 28 is connected to the lower end of the secondary cooling box 18. After the primary water inlet pipe 30 and the secondary water inlet pipe 28 are connected, one end is connected to the tap 32 through a pipe 26, and one end is connected to a water tank 27 through a pipe 26. The water tank 27 The upper part of the primary cooling box 17 and the upper part of the secondary cooling box 18 are connected through the outlet pipe 22. The water tank 27 is also connected to the water pump 25. The upper end of the gas flow meter 29 and the upper end of the spare gas flow meter 31 are respectively connected to the inner cavity of the furnace. 11 connection, the lower end of the gas flow meter 29 and the lower end of the backup gas flow meter 31 are connected to the gas supply source 13 and the backup gas supply source 14 respectively. The feed gate 8 is provided with a sealed bearing 7, and the discharge The door 20 is provided with a temperature measuring hole 19.

[0015] The working process of the present invention will be further described below.

[0016] When the product is heated, the loading boat 15 containing the product is placed in the cavity 11 of the furnace, the feed door 8 is closed, the motor 1 is started, the motor 1 drives the gear a2, the gear a2 drives the gear b3, the gear b3 drives the gear c4, and the gear c4 The internal tooth pattern drives the threaded push rod 5 to advance at a constant speed, the threaded push rod 5 drives the push rod 6 to advance at a constant speed, and the push rod 6 drives the loading boat 15 to advance at a uniform speed through the sealed bearing 7. This uniform speed ensures the uniformity of the product and also improves The working efficiency is improved; the heated loading boat 15 enters the first-level cooling box 17, the water in the water tank 27 enters the first-level cooling box 17 from the first-level water inlet pipe 30, and then is discharged into the water tank 27 through the water outlet pipe 22, so One cycle can cool the product continuously. When the water in the water tank 27 is too hot, the hot water can be pumped out by the water pump 25 for bathing or washing clothes, which saves water resources; after the first-level cooling tank 17 is cooled The product is cooled by the secondary cooling box 18, so that the cooling effect is better; the feed door 8 is closed during the processing, which also saves energy, and the protective gas from the gas source 13 enters the furnace cavity through the pipe 26 11 Protect the product, and the spare gas supply 14 also guarantees the normal supply of protective gas; during processing, excess gas can be ignited from the exhaust pipe 10 and discharged into the air. When the loading boat 15 is added, the throttle valve 9 is closed It can prevent harmful gases from entering the air, causing danger; excess water during processing is discharged from the sewage mechanism 21 through the filter 16; for the temperature of the furnace cavity 11 during the processing, an optical pyrometer can be used to pass through the temperature measuring hole 19 Measurement; the discharge door 20 can use the adjustment screw 23 to adjust the balance device 24 to maintain the level of the furnace cavity 11, to avoid product deformation during the cooling process.
