Abstract
The utility model belongs to the improvement of heater for rolling steel sidewall peephole device structure, particularly a kind of heating furnace side wall peephole device of improvement, be included in the peephole device that heater for rolling steel side wall is installed, the sighting tube of peephole device is arranged on by connecting plate on the peep-hole of heating furnace side wall, in the ring flange front portion of the front end of sighting tube, heat resistant glass and shield are installed successively, sighting tube between connecting plate and ring flange is installed with compressed air ring pipe, sweeping head uniform on compressed air ring pipe stretches in sighting tube by through hole uniform on sighting tube, fill valvular compressed air piping and be connected to compressed air ring pipe.It is rational in infrastructure, when observing situation in heating-furnace, can block the high-temperature flue gas in stove, preventing furnace high-temperature flue gas from overflowing, and protection peep-hole and heat resistant glass are not burned, and can prevent operating personnel from not scalded or anthracemia by high-temperature flue gas.
Description
Technical field
The utility model belongs to the heating furnace side wall peephole device of the improvement of heater for rolling steel sidewall peephole device structure, particularly a kind of improvement.
Background technology
The effect of heater for rolling steel sidewall peep-hole: for observing situation and burner flame situation in stove, be arranged on side wall, with shield.When needing to observe body of heater, shield is rotated to top, checks situation in stove through heat resistant glass.
Problems existing:
1, after the shield of peep-hole is threaded to top, occur the gap that a 15mm is wide between heat resistant glass and the observation panel of peep-hole, the high-temperature flue gas in stove can overflow from gap, burns out peep-hole, and time serious, the flue gas spilling personnel that cause scald and anthracemia.
2, heat resistant glass and furnace high-temperature flue gas do not completely cut off, and heat resistant glass is easily stained, and does not see in stove.
Utility model content
The purpose of this utility model is the heating furnace side wall peephole device providing a kind of improvement; it is rational in infrastructure; when observing situation in heating-furnace; the high-temperature flue gas in stove can be blocked; prevent furnace high-temperature flue gas from overflowing; protection peep-hole and heat resistant glass are not burned, and can prevent operating personnel from not scalded or anthracemia by high-temperature flue gas.
The purpose of this utility model is the heating furnace side wall peephole device providing a kind of improvement, be included in the peephole device that heater for rolling steel side wall is installed, the sighting tube of peephole device is arranged on by connecting plate on the peep-hole of heating furnace side wall, in the ring flange front portion of the front end of sighting tube, heat resistant glass and shield are installed successively, sighting tube between connecting plate and ring flange is installed with compressed air ring pipe, sweeping head uniform on compressed air ring pipe stretches in sighting tube by through hole uniform on sighting tube, fill valvular compressed air piping and be connected to compressed air ring pipe.
The utility model increases annular compression air scavenging conduit on the sighting tube of heating furnace peep-hole, arranges the sweeping head of 4 band angles.When needing to observe situation in stove, first open compressed air scavenging conduit valve, then shield is opened.After observation, first close shield, then closes compression air door.
The good effect that the utility model produces:
Use compressed air to carry out isolated furnace high-temperature flue gas, compressed-air actuated pressure and flow velocity are greater than pressure and the flow velocity of furnace high-temperature flue gas, serve the effect of sealing gland.Protect peep-hole and heat resistant glass is not burned, also protect operating personnel and do not scalded or anthracemia by high-temperature flue gas.
The utility model is rational in infrastructure; when observing situation in heating-furnace, achieving the high-temperature flue gas blocked in stove, preventing furnace high-temperature flue gas to overflow; protect peep-hole and heat resistant glass is not burned, it also avoid operating personnel simultaneously and do not scalded or anthracemia by high-temperature flue gas.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is perspective view of the present utility model.
Detailed description of the invention
A kind of heating furnace side wall peephole device of improvement, as shown in Figure 1, be included in the peephole device that heater for rolling steel side wall is installed, the sighting tube 1 of peephole device is arranged on by connecting plate 4 on the peep-hole of heating furnace side wall, in ring flange 2 front portion of the front end of sighting tube 1, heat resistant glass and shield 3 are installed successively, sighting tube 1 between connecting plate 4 and ring flange 2 is installed with compressed air ring pipe 5, sweeping head 6 uniform on compressed air ring pipe 5 stretches in sighting tube 1 by through hole uniform on sighting tube 1, the compressed air piping 7 that valve 8 is housed is connected to compressed air ring pipe 5.The quantity of sweeping head 6 is 3-4.
Claims (2)
