But the bell of tilting roller-type resistance rotary furnace
Technical field
The present invention relates to a kind of bell, but particularly a kind of bell of tilting roller-type resistance rotary furnace.
Background technology
At present, but the bell of many RG series tilting roller-type resistance rotary furnaces that my company uses is: as shown in Figure 1, but tilting roller-type resistance rotary furnace charging and discharging mouth is a hollow circle tube cylindrical shell, and two projections are housed on cylindrical drum, and these two projections are on the diameter line of cylindrical drum.Suit one bell on cylindrical drum.The bell front end is the cylinder that an iron and steel is made, and the outer ring of this cylinder and the inner ring of cylindrical drum are equipped with.The length of this cylinder is identical with the length of cylindrical drum or close.The cylinder front end is connected with preceding shrouding.Rear seal-cover is equipped with in the cylinder rear end, and there is a circle cylinder flanging rear seal-cover outer ring, and the outer ring of this cylinder flanging inner ring and cylindrical drum is equipped with.Have poor mouthful of two inclination shape cards on the cylinder flanging, two inclination shape cards are equipped with two projections for poor mouthful, and promptly two projections can be inlaid in two inclination shape draw-in groove mouths and bell is covered on cylindrical drum.Two rotating handleses also are housed on the rear seal-cover.The rotation rotating handles can be contained in bell on the cylindrical drum or bell to be unloaded down from cylindrical drum.The preceding shrouding of bell and the centre of rear seal-cover all have venthole.
The bell of said structure is long because of the length that cylinder stretches into cylindrical drum, and the cylinder front end is Yin Gaowen and be out of shape and damage very easily near furnace high-temperature flame place.This structure also makes the fire door heat distribute many and the waste furnace heat.High temperature to rear seal-cover and rotating handles place, makes the rotating handles temperature very high through the cylinder direct heat transfer in addition, the too high operating personnel's operating difficulties that makes of rotating handles temperature.
Summary of the invention
But the bell that the purpose of this invention is to provide a kind of tilting roller-type resistance rotary furnace.The cylinder of this bell is not subject to the influence of thermal-flame and is out of shape and damages.This bell make the fire door heat distribute less and the furnace heat loss less.The rotating handles temperature is hanged down and is convenient to operating personnel's operation.
Technical scheme of the present invention is: but a kind of bell of tilting roller-type resistance rotary furnace.But the charging and discharging mouth of tilting roller-type resistance stove is a hollow circle tube cylindrical shell.Two projections are housed on cylindrical drum, and these two projections are on the diameter line of cylindrical drum.Suit one bell on cylindrical drum.In the middle of the bell is the cylinder that an iron and steel is made, and the outer ring of the cylinder in the middle of the bell and the inner ring of cylindrical drum are equipped with.Rear seal-cover is equipped with in the cylinder rear end, and there is a circle cylinder flanging rear seal-cover outer ring, has poor mouthful of two inclination shape cards on the cylinder flanging, and two rotating handleses also are housed on the rear seal-cover.Be characterized in: the bell cylinder is the short cylinder body, and the length of this short cylinder body is 1/3 ± 10% of cylindrical drum.The short cylinder body front end of bell is a through hole.Be provided with the high temperature resistant escape pipe of a hollow in the middle of the short cylinder body, this hollow is high temperature resistant escape pipe front end affixed one high temperature resistant circular steel baffle plate, the setting of this is high temperature resistant circular steel baffle plate and resistance furnace cylindrical drum inner ring tight fit.This is high temperature resistant, and the circular steel baffle plate is positioned at the inner port of cylindrical drum.Hollow is high temperature resistant, and escape pipe intermediate throughholes front end passes high temperature resistant circular steel baffle plate is connected with burner hearth, and hollow is high temperature resistant, and escape pipe rear end and rear seal-cover are affixed.It is external that the rear seal-cover through furnace is passed in the intermediate throughholes rear end of the high temperature resistant escape pipe of hollow.
But advantage of the present invention has provided a kind of bell of tilting roller-type resistance rotary furnace.The cylinder of this bell is not subject to the influence of thermal-flame and is out of shape and damages.This bell make the fire door heat distribute less and the furnace heat loss less.The rotating handles temperature is hanged down and is convenient to operating personnel's operation.

The specific embodiment
Embodiment as shown in Figure 2 is as follows: but a kind of bell of tilting roller-type resistance rotary furnace.But the charging and discharging mouth of tilting roller-type resistance stove is a hollow circle tube cylindrical shell 1.Two projections 3 are housed on cylindrical drum 1.Suit one bell 5 on cylindrical drum 1.In the middle of the bell 5 is the cylinder 7 that an iron and steel is made, and the outer ring of the cylinder 7 in the middle of the bell 5 and the inner ring of cylindrical drum 1 are equipped with.Rear seal-cover 8 is equipped with in cylinder 7 rear ends, and there is a circle cylinder flanging 4 rear seal-cover 8 outer rings, have two inclination shape cards on the cylinder flanging 4 poor mouthful 10, and two rotating handleses 2 also are housed on the rear seal-cover 8.Be characterized in: bell 5 cylinders are short cylinder body 12, and the length of this short cylinder body 12 is 1/3 ± 10% of cylindrical drum 1 length.Short cylinder body 12 front ends of bell 5 are through hole 13.Be provided with the high temperature resistant escape pipe 11 of a hollow in the middle of the short cylinder body 12, this hollow is high temperature resistant escape pipe 11 front ends affixed one high temperature resistant circular steel baffle plate 14, circular steel baffle plate 14 and resistance furnace cylindrical drum 1 inner ring tight fit setting that this is high temperature resistant.This is high temperature resistant, and circular steel baffle plate 14 is positioned at the inner port 15 of cylindrical drum.Hollow is high temperature resistant, and escape pipe 11 intermediate throughholes front ends pass high temperature resistant circular steel baffle plate 14 is connected with burner hearth, and hollow is high temperature resistant, and escape pipe 11 rear ends and rear seal-cover 8 are affixed.It is external that rear seal-cover 8 through furnaces are passed in the intermediate throughholes rear end of hollow is high temperature resistant escape pipe 11.
