Abstract

The utility model relates to a furnace door regulating device which comprises a sleeve and a rotating shaft for supporting the sleeve to rotate, wherein two ends of the rotating shaft are fixed on a furnace body, the sleeve is fixed with a connecting rod, the connecting rod is connected with a furnace door, the rotating shaft is a bolt shaft, an adjusting nut is arranged on the rotating shaft at the bottom of the sleeve, when the furnace door sags for long-term use or by gravity, the up and down positions of the furnace door can be regulated by rotating the adjusting nut, thereby saving time and force and bringing convenience to use.

Description

The fire door adjusting device

Technical field

This practical technique relates to a kind of fire door adjusting device, belongs to field of mechanical technique.

Technical background

On industrial furnaces such as a lot of large-sized boilers, high temperature furnace, reduction furnace, because be to add needs such as fuel, raw material or discharging, pressurize, supercharging, the fire door own wt is bigger, in use for some time, because gravity factor, easily sagging, the distortion of fire door makes the fire door size have trickle gap, causes fire door can't close tightly, influence the temperature or the pressure of stove, so just must remove again, install again after the correction, waste time and energy very much.

The utility model content

Problem to be solved in the utility model is at above deficiency, and a kind of fire door adjusting device is provided, and can adjust the position of fire door, and is easy to use.

In order to overcome the above problems, the technical scheme that the utility model is taked is as follows: the fire door adjusting device, comprise the rotating shaft that sleeve pipe, supporting sleeve rotate, the two ends of rotating shaft are fixed on the body of heater, be fixed with connecting rod on the sleeve pipe, connecting rod connects fire door, and it is characterized in that: described rotating shaft is a bolt shaft, and the rotating shaft of sleeve bottom is provided with adjusting nut.

The utility model adopts above technical scheme, compared with prior art, has the following advantages: when fire door is long-term use or because of the gravity effect sagging after, rotatable adjusting nut is regulated the upper-lower position of fire door, and is time saving and energy saving, easy to use.

Below in conjunction with drawings and Examples the utility model is further specified.

Description of drawings

Accompanying drawing 1 is the structural representation of fire door adjusting device among the utility model embodiment;

Accompanying drawing 2 is the partial enlarged drawing of accompanying drawing 1;

Among the figure,

The 1-fire door, 2-connecting rod, 3-rotating shaft, 4-sleeve pipe, 5-adjusting nut.

The specific embodiment

Embodiment, as shown in Figure 1 and Figure 2, the fire door adjusting device, comprise the rotating shaft 3 that sleeve pipe 4, supporting sleeve 4 rotate, the two ends of rotating shaft 3 are fixed on the body of heater, are fixed with connecting rod 2 on the sleeve pipe 4, and connecting rod 2 is rotatably connected with fire door 1, rotating shaft 3 is a bolt shaft, the rotating shaft 3 of sleeve pipe 4 bottoms is provided with adjusting nut 5, when fire door is long-term use or because of the gravity effect sagging after, rotatable adjusting nut 5 is regulated the upper-lower position of fire door, time saving and energy saving, easy to use.
