Abstract
The utility model relates to a control device for a coating and plating layer on the surface of a metal band material, particularly a double nozzle air knife device for coating and plating. The double nozzle air knife device for coating and plating comprises a spray box, a nozzle, an expansion joint, an air flow regulating valve, a pressure gauge, a branch pipe and a main pipe. The utility model is characterized in that the spray box is designed into an upper layer and a lower layer; the nozzle comprises upper nozzles and lower nozzles; the spray box, the nozzle, the expansion joint and the branch pipe are respectively provided with a set; the nozzle is fixedly connected with the spray box which is connected with the branch pipe by the expansion joint; an upper branch pipe and a lower branch pipe are connected with the main pipe, and the spray box is provided with the pressure gauge; the branch pipe is provided with the air flow regulating valve, and a pair of upper nozzles and a pair of lower nozzles are installed in a parallel way; the corresponding positions of the upper nozzles and the lower nozzles are regulated, and the nozzle is a sliting type nozzle air knife. The utility model can control the evenness of the surface coating of the band steel and can reduce the coating thickness so as to enhance the quality of coating and reduce coating cost.
Description
(1) technical field
The utility model relates to sheet metal strip surface coated layer control device, relates in particular to coating twin nipple airblade device.
(2) background technology
In order to prevent the belt steel product surface oxidisation, zinc-plated, finish coatings processing such as (colour coated plate) that the belt steel surface of being everlasting carries out.A key device in pot galvanize and japanning treating processes is an air knife.Good airblade device can effectively be controlled the homogeneity and the thickness of belt steel surface coating well.The airblade device that uses all is single nozzle air knives at present, when the vibration of band steel, changed the spacing of air knife nozzle and belt steel surface in the moment of vibration, the band steel during near the nozzle of a side then simultaneously again away from another nozzle, can cause this moment belt steel surface light and dark striped-vibration line to occur, the vibration schlieren has been rung the quality of band steel coating.For than flash plating, air knife should reduce apart from the belt steel surface distance, and for the single nozzle air knife, the too little meeting of this distance makes coating hole occur, as hot-dip galvanized layer thickness＜40g/m
2The time, be difficult to control out thin like this zinc layer with existing single nozzle air knife.
(3) summary of the invention
The purpose of this utility model is to provide a kind of coating twin nipple airblade device, and this twin nipple airblade device can be controlled the homogeneity of belt steel surface coating, and energy attenuate coat-thickness, thereby improves coating quality, reduces the coating cost.
The utility model is achieved in that a kind of coating twin nipple airblade device, comprise spray box, nozzle, expansion joint, air volume regulating valve, tensimeter, arm, house steward, it is characterized in that spray box is two-layer up and down, nozzle is a upper spray nozzle, following nozzle, spray box, nozzle, expansion joint, arm respectively is a cover, the affixed spray box of nozzle, spray box is through the expansion joint connecting branch, two are propped up the pipe coupling house stewards up and down, spray box is equipped with tensimeter, and arm is equipped with air volume regulating valve, and a pair of upper spray nozzle and a pair of nozzle are down installed side by side, the relative position of upper spray nozzle and following nozzle can be regulated, and nozzle is the narrow slit type nozzle air knife.
Above-mentioned coating twin nipple airblade device, the spacing of a pair of nozzle down of the gap ratio of described a pair of upper spray nozzle is short.
Basic ideas of the present utility model are to adopt double-deck air knife that the belt steel surface coating is carried out secondary control, to reach the purpose that improves coating quality.Adopt the twin nipple air knife, carry out in pot galvanize (or japanning) operation process at the band steel, when the vibration of band steel, when the vibration line appearred in the air knife place of below, the air knife of top can be revised this vibration line.This is because up and down the spacing between the air knife is less, and coating does not solidify after through the below air knife as yet fully, and the top air knife then can continue to control thickness of coating.Can alleviate or eliminate the vibration line like this.For even minimizing thickness of coating, can be by regulating up and down nozzle apart from the distance of band steel and the whiff pressure of nozzle up and down, make the below nozzle far away apart from the band steel, and the top nozzle is near relatively apart from the band steel, just can realize the insurmountable difficult problem of single nozzle air knife, make coat-thickness not only thin but also even.
The utility model can be controlled the homogeneity of belt steel surface coating, and energy attenuate coat-thickness, thereby improves coating quality, reduces the coating cost.
(4) description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model coating twin nipple airblade device structural representation;
Among the figure: 1 band steel, 2 spray boxs, 3 expansion joints, 4 air volume regulating valves, 5 tensimeters, 6 arms, 7 house stewards, 8 upper spray nozzles, 9 times nozzles, 10 zinc pots, 11 zinc liquid.
(5) embodiment
Referring to Fig. 1, a kind of coating twin nipple airblade device comprises spray box 2, nozzle, expansion joint 3, air volume regulating valve 4, tensimeter 5, arm 6, house steward 7.Spray box 2 is two-layer up and down, and nozzle is upper spray nozzle 8, following nozzle 9, and spray box 2, nozzle, expansion joint 3, arm 6 respectively are a cover.Nozzle 8,9 is by the affixed spray box 2 of welding, and spray box 2 is through expansion joint 3 connecting branches 6, and two arms 6 connect house steward 7 up and down, and spray box 2 is equipped with tensimeter 5, and arm 6 is equipped with air volume regulating valve 4.The gas of two-layer spray box 2 is supplied with by arm 6 separately respectively, and the gas flow in the spray box 2 is by air volume regulating valve 4 controls.A pair of upper spray nozzle 8 and a pair of nozzle 9 are down installed side by side, and the relative position of upper spray nozzle 8 and following nozzle 9 can be regulated, and upper and lower nozzle 8,9 can be regulated separately apart from band steel 1 surface distance.The spacing of a pair of nozzle 9 down of the gap ratio of a pair of upper spray nozzle 8 is short, is convenient to the attenuate coat-thickness like this.The spacing of upper and lower nozzle 8,9 is determined by test.Nozzle 8,9 is the narrow slit type nozzle air knife, is made by stainless steel.
When the zinc liquid 11 of band steel 1 from zinc pot 10 (or japanning pond) when coming out to enter between the twin nipple air knife, 9 pairs of zinc layers of following nozzle (coating) carry out control first time, and 8 pairs of zinc layers of upper spray nozzle (coating) carry out the second time and control.Because upper and lower nozzle 8,9 distances are near, the coating that nozzle 9 is handled under the warp is not solidified as yet fully, and coating is more even after upper spray nozzle 8 is handled.
For uniform attenuate coating, upper spray nozzle 8 can be adjusted to than following nozzle 9 more recently apart from the distance of belt steel surface.
