Abstract
The utility model provides a furnace roller cooling device which comprises a hollow furnace roller body as well as a water inlet and a water outlet formed in two ends of the roller body, wherein the water inlet is connected with a water inlet hose; the water outlet is connected with a furnace area water return pump station through a water outlet tube. The furnace roller cooling device is characterized in that an opened water collecting tank is arranged between the water outlet tube connected with the water outlet of the furnace roller and the furnace area water return pump station; the opened water collecting tank is arranged below the water outlet tube; the water collecting tank is further connected with the furnace area water return pump station; the water inlet hose can be connected with a high-pressure water source or a high-pressure gas source. By adopting the furnace roller cooling device, scaling substances inside the furnace roller body and at the water outlet can be effectively flashed and washed, the problem that the cooling effect is not good as circulated cooling water inside the roller body does not flow smoothly is avoided, and moreover the water discharge amount of the circulated water can be observed, so that the device can be overhauled in time.
Description
Technical field
The utility model relates to metal plate and belt hot dip process technical field, relates in particular to the refrigerating unit of a kind of hot dip process Zhong Lu district furnace bottom conveying roller.
Background technology
Metal plate and belt is carried out to continuous hot-dipping, according to process requirements, need, in Lu district, metal plate and belt is carried out to high-temperature heating treatment, Er Lu district bottom arranges conveying roller at the bottom of a grate furnace, the effect that metal plate and belt is carried and transported, metal plate and belt is placed on furnace bottom conveying roller, Lu advances in district, because the stove head of district phase is in the high temperature of 1000 DEG C-1300 DEG C, need to carry out cooling operation to furnace bottom conveying roller, if cooling performance is bad, body surface dross speed is accelerated, furnace roller is yielding does not even turn.Not only affected quality product, the frequent also delay of, replacing large to furnace roller loss is simultaneously produced.
At present, to the cooling employing of furnace roller maximum be water-cooling pattern, in furnace bottom roll rod body logical in regularly recirculated cooling water being passed into, it is lowered the temperature, but, because this method adopts recirculated water refrigeration, its furnace roller water side all adopts the mode of connection of sealing, can not access high-pressure water or high-pressure air source effectively cleans the foulant of furnace roller inwall formation, cause the obstruction of roll body, have a strong impact on its cooling performance, and cannot observe the water outlet situation of furnace roller water outlet, cannot judge the working order of furnace roller, incur loss through delay the servicing time of furnace roller, the mode of connection of its sealing, also form the inner prerequisite that produces vapour lock of furnace roller, be easy to produce vapour lock in the whole recycle system, hinder the circulating cooling of water coolant.
Utility model content
In the roll body occurring when solving above-mentioned employing tradition circulating water furnace roller, producing foulant cannot clean, affect cooling performance, and easily produce the problem of air-resistance phenomenon, the utility model provides a kind of novel furnace roller refrigerating unit, logical furnace roller body in comprising, and the water-in and the water outlet that arrange at roll body two ends, described water-in is connected with water supply hose, described water outlet is connected by rising pipe Yu Lu district backwater pumping plant, between the rising pipe and described stove district backwater pumping plant that it is characterized in that connecting at described furnace roller water outlet, one open water-accepting tank is set, and described open water-accepting tank is arranged on described rising pipe lower position, and water-accepting tank below connects described stove district backwater pumping plant again, and, described water supply hose can be connected with water blast gun, described water supply hose can be connected with compression external gas source.
This is novel owing to being provided with an open pond between furnace roller rising pipe Yu Lu district backwater pumping plant, make after recirculated cooling water enters into roll body, first be discharged in open pond, afterwards, be transferred again in stove district backwater pumping plant, therefore, can be in furnace roller water inlet access high-pressure water or high-pressure air source, timing is washed away cleaning to the foulant producing in furnace roller body, and adopt open because this follows bad water cooling mode simultaneously, the air-resistance phenomenon of just having avoided enclosed circulation to produce, effectively prevent the circulation not smooth problem that recirculated water produces because of foulant obstruction or air-resistance phenomenon, improve the cooling performance of whole furnace roller.And, following bad water is directly discharged into open pond from furnace roller rising pipe, producers can observe the parameter such as water displacement situation and temperature at discharging condensate of furnace roller at any time, judge in furnace roller body, whether to occur stopping up not smooth phenomenon with this, to access in time high-pressure water or high-pressure air source, to clearing up in roll body, guarantee the real-time monitoring of recirculated cooling water.
Brief description of the drawings
The structural representation of the furnace roller refrigerating unit that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, the furnace roller refrigerating unit that the utility model provides, logical furnace roller body 1 in comprising, and the water-in 2 and the water outlet 3 that arrange at roll body 1 two ends, and, water-in 2 is connected with water supply hose 4, water outlet is connected with rising pipe 5, and an open pond 6 is set below rising pipe 5, and below open pond 6, is directly connected with stove district backwater pumping plant 7, recirculated water You Lu district backwater pumping plant 7, after cooling process, is transported in furnace roller body again.
Furnace roller water supply hose 4 can arrange rapid-acting coupling, sets up hydrant or the high-pressure water that can be connected with water supply hose 4 fast near stove district.During the routine in Lu district is maked an inspection tour, as found, recirculated cooling water is discharged to when the water yield in open pond 6 obviously reduces or furnace roller rotates abnormal (body of roll slight deformation), recirculated cooling water is switched to fire water or the external high-pressure water that pressure is higher, and the inwall to furnace roller body 1 and water outlet 3 and rising pipe 5 are cleared up and are dredged.Vapour lock or foulant are blocked after elimination, and furnace roller body of roll slight deformation can be recovered, and furnace roller can normal rotation.After fault is got rid of, reuse the recirculated cooling water of conventional hydraulic pressure.While stopping line, can utilize the foulant of high pressure fire fighting water or high-pressure air cleaning furnace roller inwall.
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.
Claims (3)
1. a furnace roller refrigerating unit, logical furnace roller body in comprising, and the water-in and the water outlet that arrange at roll body two ends, described water-in is connected with water supply hose, described water outlet is connected by rising pipe Yu Lu district backwater pumping plant, between the rising pipe and described stove district backwater pumping plant that it is characterized in that connecting at described furnace roller water outlet, one open water-accepting tank is set, and described open water-accepting tank is arranged on described rising pipe lower position, and water-accepting tank below connects described stove district backwater pumping plant again.
