Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A heat penetration pretreatment walking beam heating furnace comprises a shell 1, a heating component 2 is arranged inside the shell 1, and protection components 3 are arranged on both sides of the shell 1;

[0031] The heating assembly 2 includes an electric winch 201, a winding steel cable 202, a placement plate 203 and a heater 204. The electric winch 201 is arranged on the top of the shell 1, the winding steel cable 202 is wound around the surface of the electric winch 201, the placement plate 203 is bolted to the bottom of the winding steel cable 202, and two heaters 204 are arranged on both sides of the shell 1. The heaters 204 are located on both sides of the placement plate 203, and the winding steel cable 202 and the placement plate 203 are located inside the shell 1.

[0032] Specifically, Figure 3 and Figure 5 As shown, the protection component 3 includes an auxiliary plate 301 and a reinforcement plate 302. The auxiliary plate 301 is arranged below the heater 204, and the reinforcement plate 302 is arranged on both sides of the shell 1. The auxiliary plate 301 and the reinforcement plate 302 are made of 310 stainless steel.

[0033] Specifically, Figure 1 and Figure 2 As shown, a ventilation bin 4 is disposed on one side of the housing 1 , an inlet fan 5 is disposed on one side of the ventilation bin 4 , and the inlet fan 5 is located on one side of the placement plate 203 .

[0034] Specifically, Figure 2 As shown, a protective plate 6 is provided inside the ventilation bin 4, and dust collecting holes 7 are provided at the top and bottom of the protective plate 6.

[0035] Specifically, Figure 2 As shown, a dust storage tank 8 is provided below the protection plate 6 .

[0036] Specifically, Figure 2 As shown, a dust outlet 9 is opened on one side of the bottom of the shell 1, and the dust outlet 9 is located on one side of the dust storage tank 8.

[0037] The electric winch 201 drives the placement plate 203 to move up and down by winding the steel cable 202, so as to adjust the position of the objects placed on the placement plate 203. The heaters 204 located on both sides of the shell 1 heat the objects on the placement plate 203. At the same time, the auxiliary plate 301 in the protection component 3 is located below the heater 204 for support and heat insulation. When the rising workpiece is heated, the heat rises and contacts the workpiece to reduce heat loss, and the reinforcement plate 302 strengthens the structural strength of the shell 1 to ensure stable operation of the equipment. In addition, the equipment is also equipped with a ventilation system, including a ventilation bin 4 and an inlet fan 5 arranged on one side of the shell 1. The inlet fan 5 provides fresh air to the heating area to ensure air circulation during the heating process and prevent overheating. A protective plate 6 is arranged inside the ventilation bin 4, and the dust collection hole 7 thereon allows dust to fall into the dust storage tank 8 below to keep the inside of the equipment clean. Finally, the dust collected in the dust storage tank 8 can be cleaned through the dust outlet 9 at the bottom of the shell 1 to maintain long-term stable operation of the equipment.

[0038] Specifically, Figure 5 As shown, carrying handles 10 are provided on both sides of the housing 1 .

[0039] Specifically, Figure 5 As shown, a support plate 11 is provided at the bottom of the shell 1 , and an inclined leg 12 is provided at the bottom of the ventilation bin 4 .

[0040] The carrying handles 10 arranged on both sides of the shell 1 provide convenient gripping points for the operator, so that the device can be easily moved or adjusted when it needs to be moved or adjusted. This design not only improves the portability of the device, but also reduces the labor intensity of the operator during the carrying process. At the same time, the support plate 11 arranged at the bottom of the shell 1 plays a role in enhancing the stability of the device. The support plate 11 ensures that the device can stably contact the ground when placed to prevent tilting or sliding caused by uneven ground or unstable center of gravity of the device, which ensures the stability and safety of the device during the heating process. In addition, the tilt of the bottom of the ventilation bin 4 The leg 12 design helps to discharge dust and impurities. During the ventilation process, the generated dust and impurities will accumulate in the ventilation bin 4. The design of the inclined legs 12 allows these dust and impurities to flow more easily to the dust storage trough 8. A protective plate 6 is provided inside the ventilation bin 4. The dust collection holes 7 thereon allow dust to fall into the dust storage trough 8 below to keep the inside of the equipment clean. Finally, the dust collected in the dust storage trough 8 can be cleaned through the dust outlet 9 at the bottom of the shell 1 to maintain the long-term stable operation of the equipment, thereby keeping the inside of the ventilation bin 4 clean, which further enhances the reliability and service life of the equipment.

[0041] By adopting the above technical solution, the problem that the step heating method of the existing heating furnace is horizontal heating, which easily leads to heat loss and affects the processing quality of the workpiece is solved.

[0042] Working principle: When the present application is in use, first, the electric winch 201 drives the placement plate 203 to move up and down by winding the steel cable 202, so as to adjust the position of the items placed on the placement plate 203, and the heaters 204 located on both sides of the shell 1 heat the items on the placement plate 203. At the same time, the auxiliary plate 301 in the protection component 3 is located below the heater 204 for support and heat insulation, and when the rising workpiece is heated, the heat rises and contacts the workpiece, reducing heat loss, and the reinforcement plate 302 strengthens the structural strength of the shell 1 to ensure stable operation of the equipment. In addition, the equipment is also equipped with a ventilation system, including a ventilation bin 4 and an inlet fan 5 arranged on one side of the shell 1. The inlet fan 5 provides fresh air to the heating area to ensure air circulation during the heating process and prevent overheating. A protective plate 6 is arranged inside the ventilation bin 4, and the dust collection hole 7 thereon allows dust to fall into the dust storage tank 8 below to keep the inside of the equipment clean. Finally, the dust collected in the dust storage tank 8 can be cleaned through the dust outlet 9 at the bottom of the shell 1 to maintain long-term stable operation of the equipment.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
