[0002] A heat treatment furnace refers to a heating furnace that performs heat treatment on materials of different materials.

[0003] The use of heat treatment furnaces can more conveniently heat treat materials of various materials and improve the efficiency of material processing. In actual use, heat treatment furnaces generally need to use wind as a temperature medium to heat or cool materials. However, when the existing heat treatment furnaces use fans to supply air to the interior of the furnace body, the structural principle of the fan impeller will cause the wind force in the center to be smaller and the wind force around to be larger, which will lead to inconsistent temperatures in the middle and above and below the furnace, affecting the treatment effect of the heating furnace.

[0004] Therefore, we provide a heat treatment furnace air guide hood. Utility Model Content

[0005] The utility model aims to solve the above-mentioned technical problems and provide a heat treatment furnace air guide cover to achieve the effect of smooth and uniform air flow.

[0006] In view of this, the utility model provides a heat treatment furnace air guide hood, comprising a fan, and an air guide hood fixedly arranged on one side of the fan, a guide plate and an auxiliary guide plate fixedly connected inside the air guide hood, there are a plurality of guide plates and a plurality of auxiliary guide plates, and the guide plates and the auxiliary guide plates are symmetrically distributed, a converging cone is arranged in the middle of the air guide hood, the converging cone is located between the guide plate and the auxiliary guide plate, a support frame is arranged inside the air guide hood, the support frame is fixedly connected to the converging cone, the guide plate and the auxiliary guide plate are both located between the support frame and the air guide hood.

[0007] Preferably, a support rod is fixedly connected to the outer side of the support frame, and there are several support rods.

[0012] Preferably, the rotating connecting shaft is rotatably connected to a supporting shell, the supporting shell is fixedly connected to the air guide cover, and the rotating fan blades are located inside the supporting shell.

[0013] Compared with the prior art, the utility model provides a heat treatment furnace air guide cover, which has the following beneficial effects:

[0014] The utility model can collect and guide the wind generated by the rotating fan when it is running and then circulate it into the heating furnace under the guidance of the deflector cover. When the wind flows inside the deflector cover, the setting of the confluence cone avoids the problem of uneven air outlet caused by too small wind force at the center of the fan impeller, so that the wind can be discharged evenly in all directions through the guiding effect of the deflector cover.

[0015] The utility model can adjust the consistency of air outlet to the maximum extent by arranging a plurality of guide plates and guide auxiliary plates inside the guide cover at certain intervals and arranging them themselves at certain inclination angles.
