[0002] Industrial furnaces are thermal equipment that heat materials or workpieces in industrial production by using the heat from fuel combustion or electric energy conversion. As one of the components of an industrial furnace, the furnace door needs to be used to close the furnace mouth during use. The purpose is to maintain the furnace temperature, reduce the heat loss caused by radiation and furnace gas overflow, and avoid the deterioration of the furnace atmosphere due to air inhalation. The requirements for the furnace door are tight, light, durable and heat-insulated. However, traditional furnace doors usually use welding fixing plates or threaded pipe connections for installation. These methods are prone to position deviation during installation and are difficult to adjust, resulting in poor airtightness of the furnace door, and unstable installation, which can easily lead to problems such as wear and deformation of the installed components, reducing the durability of the components. Utility Model Content

The front-to-back adjustment unit includes a hanging seat that can be fixed to the furnace door, and an adjustment bolt arranged on its upper side corresponding to the adjustment hole. The adjustment bolt passes through the adjustment hole and is connected with an adjustment nut. The adjustment bolt fixes the adjustable fixing plate and the hanging seat together. The hanging seat can move forward and backward by changing the position of the adjustment bolt at the strip-shaped hole, thereby driving the furnace door to adjust its position forward and backward.
[0009] Furthermore, the lifting nut includes a nut body and a cylindrical tube at its upper end, and the adjustable fixing plate is sleeved on the outer ring of the cylindrical tube through a through hole, and the outer diameter of the cylindrical tube matches the inner diameter of the through hole, which is easy to install and can avoid direct contact between the lifting bolt and the adjustable fixing plate, thereby reducing wear between the two.
[0010] Further preferably, two lifting seats are provided opposite to each other on both sides below the adjustable fixing plate to prevent deviation and enhance the balance and stability of the structure during lifting.
[0011] Specifically, the lifting seat includes a horizontal plate, on which an adjusting bolt is arranged, and the horizontal plate is located between the nut body and the adjustable fixing plate, and can be supported by the nut body and move therewith.
[0012] Furthermore, a transition plate is provided between the horizontal plate and the nut body to increase the force-bearing surface between the horizontal plate and the nut body and enhance the structural stability.
[0013] As a preferred embodiment, a protective plate is also vertically provided on the rear side of the lifting seat to block the heat of the furnace mouth, reduce the impact of the high temperature of the furnace mouth on the lifting components, and improve their durability.
[0014] Further preferably, the lifting unit also includes a back-tightening nut which is arranged at the upper end of the lifting nut and is tightly pressed against the upper end of the column. After adjusting the lifting height of the furnace door, tightening the back-tightening nut can effectively prevent the lifting nut from loosening.
[0015] As a preferred embodiment, a fixing plate with a circular hole is provided on the outer side of the lifting seat, the bottom of the fixing plate is flush with the bottom of the lifting seat, and they are connected to the furnace door together, thereby increasing the contact surface between the lifting seat and the furnace door and enhancing stability.
[0016] The beneficial effects of the utility model are:
[0017] The lower end of the utility model is connected to the furnace door through a hanging seat, and the upper end is connected to the hanging rope through a hanging bolt. With the cooperation of the hanging unit, the upper and lower adjustment unit, and the front and rear adjustment unit, the furnace door position can be adjusted efficiently and accurately, and the furnace door installation efficiency is improved. At the same time, the airtightness of the furnace mouth is strengthened, and the stability of the combustion process in the furnace is improved. The overall structure of the utility model is compact, the connection between the various parts is flexible and reliable, it is easy to manufacture and install, and the friction loss is small and has high durability.
