Background technology
At present, the heating unit in the tempered glass heating furnace adopts matrix form stove silk layout mostly, promptly constitutes a heating zone by one or more porcelain spare unit that is wound with heater strip, again the matrix form distributed and arranged is pressed on furnace roof, furnace bottom in each heating zone.Though this matrix form layout type of heating is convenient to the temperature of each heating zone is regulated separately; But when breaking down when needing repairing in the heating zone; Its program is very loaded down with trivial details; At first process furnace must stop to produce, treat that body of heater is reduced to room temperature and blow-on after, the serviceman just can get in the body of heater remedial operatioies such as dismantling, change heater strip.Based on this maintenance mode of matrix form process furnace,, process furnace influenced the production efficiency of production process subsequently when stopping production maintenance, and its remedial operation length consuming time; Maintenance efficiency is lowly denounced by the insider; And, also often appear at when carrying out the maintenance failure heating zone near the situation of the heating zone damaging accidentally because spacing is little and exist and to interact between adjacent each heating zone; Add unnecessary maintenance cost, caused the waste of resource.
The utility model content
For solving heating unit existing problem when repairing of tempered glass heating furnace in the prior art; The purpose of the utility model is to provide a kind of novel tempered glass heating furnace that adopts the tubular type heating unit to replace existing matrix form stove silk layout; And body of heater is provided with the open hole corresponding with each heating unit; The tubular type heating unit can insert from its open hole separately or take out; The serviceman can carry out remedial operation to it outside stove, and can not have influence on the works better of other tubular type heating unit and whole process furnace.So not only guarantee the production efficiency of process furnace, also shortened servicing time greatly, saved maintenance cost.
Be to realize above-mentioned purpose, a kind of tempered glass heating furnace that has the tubular type heating unit of the utility model comprises the body of heater of upper and lower fastening being provided with into fire door and plug for outlet in the body of heater both sides, is provided with the glass conveying roller way that connects to advance fire door and plug for outlet in the body; State some radiation sleeve pipes that are respectively arranged with in the upper and lower body of heater along extension of glass sheets direction and horizontal distribution; Said radiation inside pipe casing is plugged with the tubular type heating unit; Upper and lower body of heater is provided with and the corresponding open hole of radiation sleeve pipe in the end wall that advances the fire door end, and said tubular type heating unit can be inserted or extracted by said open hole.
Further; Said tubular type heating unit comprises some ring holders, porcelain tube and heater strip; Said heater strip is wrapped on the said porcelain tube, and through heater strip joint adapter cable above that is set, lead passes said open hole and links to each other with external power source; Said some ring holders are nested with in the porcelain tube perisporium outside at interval; The external diameter of ring holder is identical with radiation telescopic internal diameter, and also is provided with the groove that supplies heater strip to pass on this ring holder, and open hole is provided with and is used for its shutoff and the sealing member of avoiding high-temperature gas to leak.
Further, said heater strip joint and said sealing member are made into integration.
Further, said heater strip partly constitutes by twining part and loop line, and wherein said winding part evenly around the home in the said porcelain tube perisporium outside, wear back along the tube chamber of porcelain tube by said loop line part.
Further, the winding of said heater strip part partly is separately made with loop line.
Further; Said heater strip twines part and adopts the big metallic substance of resistivity to process; Said heater strip loop line partly is coarser than above-mentioned winding part, and adopts the little metallic substance of resistivity to process, and the double connection of doing whole heating unit internal structure of this loop line part is supported.
Further, be provided with radial lamella between intravital radiation sleeve pipe of said upper and lower stove and the rollgang.
The utility model is through replacing the tubular type heating unit existing matrix form stove silk; And body of heater is provided with open hole; Each tubular type heating unit all can be inserted from open hole separately or take out, be convenient to the serviceman and outside process furnace, carry out remedial operation, guarantee the process furnace works better simultaneously; Process furnace is quit work and the blow-on of need not lowering the temperature gets final product remedial operation; Two kinds of maintenance modes all are to have saved servicing time greatly, have saved maintenance cost, have improved maintenance efficiency.And open hole is arranged on the end wall that upper and lower body of heater is positioned at fire door end into; Effectively utilize the space that process furnace advances before the fire door and carry out maintenance work; Avoid influencing the ordinary production of following process equipment, eliminate safe hidden trouble because the tubular type heating unit that takes out is long.Outside porcelain tube, be equipped with ring holder, avoid heater strip and radiation sleeve pipe joint, cause mutual damage, influence the work-ing life of heating unit.Through the shutoff of open hole is set, make the high temperature air in the process furnace be difficult for leaking.Heater strip loop line part is worn back from the tube chamber of porcelain tube, can guarantee effectively that the loop line part does not contact with twining part, has avoided causing local electrical resistance to reduce because of two portions contact, and influences heats, reduces the work-ing life of heater strip.And heater strip loop line part is coarser than the winding part, loop line part resistance is reduced, thereby save energy.Radial lamella has certain heat accumulation function, can make in the process furnace heat energy distribution better evenly through the radiation version is set, and improves the heats in the stove.
