Abstract
The utility model discloses a stripe steel passivation rear drying oven with an external forced circulation device, belongs to the improvement of hot galvanizing production equipment and provides the drying oven with the forced circulation device. The drying oven with the forced circulation device has small heat energy losses. According to the technical scheme, an external circulation fan and an external air duct compose an external circulation unit to guide hot air to be lost from the upper opening of the drying oven to the lower opening of the drying oven for secondary recycling. By means of forced circulation of the hot air inside the drying oven, not only are heat losses reduced, but also electric energy can be saved; meanwhile, the temperature inside the drying oven can be uniform, the drying efficiency of the drying oven on surfaces of stripe steel and the product quality can be guaranteed.
Description
Technical field
The utility model discloses a kind ofly with baking oven after the band steel passivation of outer forced circulation device, belong to the improvement of galvanizing production equipment.
Background technology
In galvanizing production process, with steel passivation post-drying, by stove silk, heat to improve oven temperature, in the process of using, the non-uniform temperature of baking oven, not only drying effect is bad, and long-term use can cause baking oven distortion, and temperature loss is also large.Because baking oven is vertical drying oven, utilize electric energy heating, band steel is again to move from bottom to top, in heating process, heat can rise outflow baking oven and scatter and disappear greatly.Can waste a large amount of electric energy like this, can not reach good drying effect, cause the decline of product quality.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides the baking oven with forced circulation device that a kind of heat-energy losses is little.
The technical solution of the utility model is: utilize the circulating fan of peripheral hardware and air channel to form external circulating device, the baking oven hot-air that is about to run off suitable for reading is guided to baking oven end opening, carry out secondary recycling.Like this hot-air in baking oven is carried out to forced circulation, both reduced the loss of heat, saved electric energy, make again the temperature inside the box even, reduce the risk of box deformation, increased the oven dry usefulness to plate face, guaranteed the quality of product.
A kind of baking oven with forced circulation device, comprise the electric heater in casing, casing, and band steel passage from bottom to top, it is characterized in that on the tank wall of steel exports, the air outlet outside identical with casing being set on the top of casing, air outlet connects air channel, and air channel is connected with the inlet scoop of air-introduced machine, and the exhaust outlet of air-introduced machine connects air channel, the other end in air channel is connected with the air inlet that the bottom of casing leads to box house, forms forced circulation system.
Air-introduced machine is a centrifugal blower, and air channel adopts heat-resistant insulation material to form.
During work, be positioned at the electric heater of lower box, the temperature inside the box is promoted, the hot-air that will flow out on casing top is constantly inhaled into air channel, air inlet from bottom enters in casing again, and the upper and lower temperature difference of casing is reduced, and heat recycling has reduced heat loss.
The utility model is sucked and heat is blown to baking oven from bottom again at the top of baking oven heat by pipeline, can play like this heat and be difficult for the effect running off, simultaneously.Baking oven is not yielding yet.Thereby played the effect making full use of of heat.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1-casing, 2-electric heater, 3-is with steel, the import of 4-band steel, 5-is with steel exports, 6-air-introduced machine, 7 air outlets, 8 air inlets, 9 air channels.
The specific embodiment
A kind of baking oven with forced circulation device, comprise the electric heater 2 in casing 1, casing, and band steel 3 passages from bottom to top, it is characterized in that on the tank wall of steel exports 4, the air outlet 7 outside identical with casing being set on the top of casing, air outlet 7 connects air channel 9, and air channel is connected with the inlet scoop of air-introduced machine 6, and the exhaust outlet of air-introduced machine 6 connects air channel 9, the other end in air channel is connected with the air inlet 8 that the bottom of casing leads to box house, forms forced circulation system.
Air-introduced machine 6 is a centrifugal blower.
Air channel 9 adopts heat-resistant insulation material to form.
In casing upper and lower part, temperature detect switch (TDS) is respectively set, temperature detect switch (TDS) is connected in series composition " with door " on-off circuit, is connected in the power supply circuits of air-introduced machine.
That the temperature detect switch (TDS) that is arranged on casing upper and lower part forms series connection and door switch circuit, connects when the temperature detect switch (TDS) on top is higher than design temperature, and the temperature detect switch (TDS) of bottom is connected during lower than design temperature, and two temperature detect switch (TDS)s determine the start-up time of air-introduced machine jointly.Be intended to guarantee that the temperature of upper and lower part has a rational gradient, be beneficial to after passivation with the oven dry of steel, also can control preferably the degree of forced circulation, be convenient to economize on electricity and be beneficial to equipment and increase the service life.
For example: generally, according to the standard furnace temperature of 220 degrees Celsius, the design temperature of the temperature detect switch (TDS) on casing top is 200 degrees Celsius, and the design temperature of the temperature detect switch (TDS) of lower box is 205 degrees Celsius, and the temperature difference of upper and lower part has less difference.
Claims (4)
