Background technology
In order to reach attractive in appearance and etch-proof object; need to carry out immersion to metal plate and belt; before applying molten metal plating solution; first must carry out pyroprocessing to reach corresponding technological temperature to metal plate and belt; in heat; need in relatively airtight heat treatment furnace, be full of nitrogen and hydrogen as shielding gas, to prevent that metal plate and belt is oxidized in heat-processed, affect subsequent thermal immersion plating effect.And protection gas is worked for a long time in body of heater, the volume of smoke that adulterating, affects metal plate and belt thermal treatment quality; and radiant-type furnace is in heat treatment process, and in its stove, temperature is often too high, adopts conventional cooling means; cooling extent is too large again, often cannot precisely control temperature in stove.And shielding gas cannot be realized its recycling in stove, cause waste.
Utility model content
In order to solve temperature in above-mentioned radiant-type furnace, cannot precisely control; and in stove, shielding gas is full of the problems such as flue dust; the utility model provides a kind of hot dip process radiant-type furnace protection gas circulation device; it is characterized in that arranging protection gas circulation line in a stove; and at stove, one cooling box is set outward; described protection gas circulation line is arranged in cooling box, and at casing top, heat-eliminating medium entrance is set, and at bottom half, heat-eliminating medium outlet is set.Meanwhile, one deck filtrating smoke dust net is at least set in described circulation line.
Above-mentioned setting; can make shielding gas in radiant-type furnace complete stove outer circulation by circulation line; in working cycle, by the cooling box arranging, reach the object of shielding gas cooling, on the one hand; shielding gas is under the effect of cooling and filtering net; complete the removal of flue dust, on the other hand, the shielding gas of being lowered the temperature is transported in radiant-type furnace again; complete the temperature fine adjustments in radiant-type furnace, realized the accurate control of temperature in stove.
Preferably, three pipelines are set in described heat-eliminating medium exit to be connected respectively to hot dip process pre-treatment pond, to help in plating solvent cell and circulating water pool, and a recycle pump machine is set in described circulating water pool, and the described recycle pump machine the other end is connected to described heat-eliminating medium ingress.And, on described three pipelines, independent by-pass valve control is set respectively.
When in giving stove, shielding gas is lowered the temperature; heat-eliminating medium heats up; by three pipelines, caused respectively hot dip process pre-treatment pond, help in plating solvent cell or circulating water pool; due to, hot dip process pretreatment liquid and to help plating solvent be optimal working temp in the time of 40 ℃-50 ℃, therefore; according to practical situation optionally heat-eliminating medium after heat exchange is heated; as water coolant etc. is directly used in pre-treatment pond or helps the preparation of plating solvent, realize the utilization of heat energy, save the energy.And arrange respectively at three pipelines three valve switch independently can effectively be controlled pre-treatment pond, help the flooding quantity of plating solvent cell, can regulate according to actual needs.And generally; close pre-treatment pond and help plating solvent cell pipe valve; only open circulating water pool valve, in cooling tank with recycle gas the heat-eliminating medium after heat exchange, be transported in circulating water pool; carry out radiating and cooling; be recycled afterwards pump machine and extract out, through pipeline, be again transported to cooling tank heat-eliminating medium ingress, again complete in cooling tank and the heat exchange of shielding gas; form cycle heat exchange, reach the hydronic object of shielding gas in stove.
The hot dip process radiant-type furnace protection gas circulation device that the utility model provides; formed the dual recycle system of shielding gas circulation with heat-eliminating medium circulation; and realized multiple effective utilization of heat energy; removed the exhaust gas dust in protection gas simultaneously; reached the fine setting of temperature in stove; and simple in structure, rationally, cheap.
Accompanying drawing explanation
The hot dip process radiant-type furnace that Fig. 1 provides for the utility model is protected the structural representation of gas circulation device.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1; the hot dip process radiant-type furnace protection gas circulation device that the utility model provides; the protection gas circulation line 1 that comprises setting; and the cooling tank 2 arranging outside radiant-type furnace body of heater; and described protection gas circulation line 1 is arranged in the casing of cooling tank 2, at the top of cooling tank 2, heat-eliminating medium entrance 3 is set simultaneously, heat-eliminating medium outlet 4 is set in the bottom of cooling tank 2; in order to connect heat-eliminating medium circulation line, complete the recycle of heat-eliminating medium.And one deck filtrating smoke dust net 5 is at least set in circulation line 1, filters and remove the flue dust impurity in protection gas in stove.At heat-eliminating medium, export 4 places and connect respectively hot dip process pre-treatment pond pipeline 6, help plating solvent pipe 7, and circulating water pool pipeline 8, article three, pipeline is passed into respectively hot dip process pre-treatment pond, helps in plating solvent cell and circulating water pool, and on pipeline 6,7,8, separate valve 6a is set respectively, 7a, 8a, reached to above-mentioned three objects that pipeline is independently controlled.Recycle pump machine 9 is set in circulating water pool, and is connected to heat-eliminating medium entrance 3 places by pipeline, complete recycling of heat-eliminating medium.
When needs to radiant-type furnace in temperature finely tune, and in the time of need to removing the flue dust in the interior protection of stove gas, start background radiation stove protection gas circulation device, by protecting gas to circulate in 1 pair of stove of protection gas circulation line, input and output, because circulation line 1 is arranged in cooling tank 2, the heat-eliminating medium entrance 3 arranging by cooling tank 2 tops passes into heat-eliminating medium, as water coolant, protection gas in water coolant and circulation line 1 carries out heat exchange in cooling tank 2, and owing to being provided with filtrating smoke dust net 5 in circulation line 1, therefore the protection gas in circulation line 1 is through cooling and the dual function of filtering, effectively removed the flue dust in protection gas, shielding gas is recycled pipeline 1 and again sends back in radiant-type furnace body of heater, by the protection gas of cooling down, also played the effect of temperature in regulating stove simultaneously.Meanwhile, water coolant completes after heat exchange with protection gas in cooling tank 2, from heat-eliminating medium outlet 4, flows out, can be according to actual needs, and regulated valve 6a, 7a, 8a, completes the conveying of water coolant after heat exchange.When hot dip process pre-treatment pond need to be with the water coolant of heat energy, can open valve 6a, valve-off 7a simultaneously, 8a, flows in pre-treatment pond the water coolant after heat exchange, realizes the utilization of heat energy in water coolant after heat exchange.If help plating solvent cell while needing heat energy, operation equally, can realize heat exchange after water coolant to helping the supply of plating solvent cell.And generally, Open valve 8a, while valve-off 6a and 7a, water coolant is flowed in circulating water pool, by the recycle pump machine 9 arranging in circulating water pool, water coolant after dispelling the heat in circulating water pool is transported to heat-eliminating medium entrance 3 places again, with this, completes the recycle of water coolant.Operation when this hot dip process radiant-type furnace protection gas circulation device has been realized heat-eliminating medium and the interior dual recycle system of shielding gas of stove.
Above-mentioned is only ultimate principle of the present utility model, any restriction of not the utility model being made, and every equivalent variations of it being carried out according to the utility model and modification, all within protection domain of the present utility model.
