Abstract
The utility model discloses a defogging air suction cover for a strip coating train of a cold rolling mill. The defogging air suction cover comprises an air suction cover body which is cast from short-fiber felt(fabric) polyester FRP lined with reinforcing steel bars, a negative-pressure air suction pipe, and an insulated heating cable wound inside the air suction cover body. A groove provided with a through hole at the bottom is arranged at the throat of the negative-pressure air suction pipe. The lower edge of the air suction cover body crimps inwards to form a semicircular groove which has a through hole at the bottom. The air suction cover body is spherical. The insulated heating cable imbedded and wound inside the air suction cover body can ensure that the temperature of the atomized water is higher than the temperature of the environment and the atomized water can be discharged by the negative-pressure air suction pipe in time to avoid condensed water drops, thus preventing drippage of the condensed water inside the air suction cover. Therefore, the defogging air suction cover ensures smooth finish and coating quality of the cold milled strip.
Description
Technical field
The utility model relates to a kind of fog discharge suspended hood of cold-rolling mill strip coating unit.
Background technology
Cold-rolling mill strip coating unit top is provided with the suspended hood of getting rid of the various fogs that strip coating produced, and the mist suspended hood adopts staple fiber batt (cloth) the organic toughened glass castable of liner reinforcing bar usually, and it is shaped as horn mouth.When environment temperature is low, the condensed water that easily forms in the fog discharge suspended hood of cold-rolling mill strip coating unit is puzzlement user's a problem, especially in the winter time, the strip of cold rolled sheet coating unit is endured the puzzlement of the condensed water of cohesion in the suspended hood to the fullest extent, owing to the drippage of condensed water, had a strong impact on the fineness and the quality of coating of cold rolled sheet.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of cold-rolling mill strip coating unit fog discharge suspended hood, and this suspended hood can effectively be avoided the drippage of condensed water in the suspended hood, thereby has guaranteed the fineness and the quality of coating of cold rolled sheet.
For solving the problems of the technologies described above, the utility model cold-rolling mill strip coating unit fog discharge suspended hood comprises the suspended hood cover body and the negative pressure sucking air pipe road that is connected with described suspended hood top of staple fiber batt (cloth) the organic toughened glass castable of liner reinforcing bar, also comprise insulation heating cable, described insulation heating cable is embedded to be wound in the described suspended hood cover body.
For preventing that condensed water flows into suspended hood cover wall in the negative pressure sucking air pipe road, above-mentioned negative pressure sucking air pipe road throat is provided with groove, and described bottom portion of groove has first through hole.
May be for the condensed water that prevents suspended hood cover wall along cover wall drippage, above-mentioned suspended hood cover body lower limb inwardly curls into half slot, and described half slot bottom has second through hole.
For the fog in the suspended hood cover body is discharged fast by the negative pressure sucking air pipe road, and make that remaining condensed water flow in the half slot along the cover wall in the cover body, above-mentioned suspended hood cover body is a dome shape.
Because the utility model cold-rolling mill strip coating unit fog discharge suspended hood has adopted technique scheme, i.e. embedded winding insulation heating cable in cover body, can ensure that atomizing moisture temperature is higher than environment temperature in the suspended hood, in time be discharged, unlikely formation condensed water drippage by the negative pressure sucking air pipe road; Further, the groove of negative pressure sucking air pipe road throat has been blocked aqueous vapor inflow suspended hood in the negative pressure sucking air pipe road, condensed water is discharged by the through hole of bottom portion of groove in the groove, the suspended hood cover body adopts spherical shape simultaneously, guarantee that remaining condensed water flow in the water storage tank of cover body lower limb half slot along the cover wall in the cover body, and by the condensed water in the through hole discharge water storage tank on half slot base.Thereby effectively avoid the drippage of condensed water in the suspended hood, guaranteed the fineness and the quality of coating of cold rolled sheet.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the utility model cold-rolling mill strip coating unit fog discharge suspended hood.
The specific embodiment
As shown in Figure 1, the utility model cold-rolling mill strip coating unit fog discharge suspended hood comprises suspended hood 1 cover body and the negative pressure sucking air pipe road 2 that is connected with described suspended hood 1 top of staple fiber batt (cloth) the organic toughened glass castable of liner reinforcing bar, also comprise insulation heating cable 3, described insulation heating cable 3 embedded being wound in described suspended hood 1 cover body.
For preventing that condensed water flows into suspended hood 1 cover wall in the negative pressure sucking air pipe road 2, above-mentioned negative pressure sucking air pipe road 2 throats are provided with groove 21, and described groove 21 bottoms have first through hole 22.
May be for the condensed water that prevents suspended hood 1 cover wall along cover wall drippage, above-mentioned suspended hood 1 cover body lower limb inwardly curls into half slot 11, and described half slot 11 bottoms have second through hole 12.
For the fog in suspended hood 1 cover body is discharged fast by negative pressure sucking air pipe road 2, and make that remaining condensed water flow in the half slot 11 along the cover wall in the cover body, above-mentioned suspended hood 1 cover body is a dome shape 13.
This fog discharge suspended hood is embedded winding insulation heating cable 3 in suspended hood 1 cover body, can ensure that atomizing moisture temperature is higher than environment temperature in the suspended hood 1, is in time discharged unlikely formation condensed water drippage by negative pressure sucking air pipe road 2; Further, the groove 21 of negative pressure sucking air pipe road 2 throats has been blocked aqueous vapor inflow suspended hood 1 in the negative pressure sucking air pipe road 2, condensed water is discharged by first through hole 22 of groove 21 bottoms in the groove, suspended hood 1 cover body adopts dome shape 13 simultaneously, guarantee that remaining condensed water flow in the water storage tank of cover body lower limb half slot 11 along the cover wall in the cover body, and by the condensed water in second through hole, the 12 discharge water storage tanks on half slot 11 bases.Thereby effectively avoid the drippage of condensed water in the suspended hood, guaranteed the fineness and the quality of coating of cold rolled sheet.
