[0023] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings of the present invention.
[0024] refer to Figure 1 and Figure 2 The blowing and suction type acid mist collecting device 100 provided in one embodiment of the utility model is suitable for a large open electroplating tank 10, and the open electroplating tank 10 has a notch 12. In the utility model, a large open electroplating tank refers to a notch 12 having a width greater than 1200 mm (millimeter), and the shape of the notch can be a positive direction, a rectangle or other shapes, and the width of the narrowest part thereof can be greater than 1200 mm.
[0025] The blowing and suction type acid mist collection device 100 includes an air suction module and an air blowing module. The air suction module includes an air suction fan (not shown in the figure), a funnel-shaped air suction hood 31 connected to the air suction fan through an air suction pipeline 36, and a flow equalizing plate 41 installed at the entrance of the air suction hood 31. The air suction hood 31 is installed on one side of the slot 12, and the entrance faces the slot 12. The flow equalizing plate 41 blocks part or all of the area of the entrance of the air suction hood 31, and the flow equalizing plate 41 is provided with a plurality of air inlets 43 passing through.
[0026] The blowing module includes a blowing fan (not shown), a blowing cover 51 connected to the exhaust fan through a blowing pipe 56, and the blowing cover 51 has a flat and long blowing port 53 (see FIG. Figure 6 The air blowing port 53 of the air blowing hood 51 is opposite to the inlet of the air suction hood 31 .
[0027] In this embodiment, there are two air suction hoods 31, which are sequentially arranged along one side of the slot 12. It is understandable that more air suction hoods 31 can be provided as needed, and the plurality of air suction hoods 31 are sequentially arranged along one side of the slot 12.
[0028] In this embodiment, there are two blowing covers 51, which are arranged in sequence along one side of the slot 12. It is understandable that more blowing covers 51 can be provided as needed, and the plurality of blowing covers 51 are arranged in sequence along one side of the slot 12.
[0029] In this embodiment, the electrolytic tank 10 includes a plurality of side panels 14. The suction hood 31 is horizontally arranged along the top edge of one of the side panels, and the blowing hood 51 is horizontally arranged along the top edge of the other side panel. Preferably, the suction hood 31 is close to the liquid surface in the electroplating tank 10, for example, the distance between the lower edge of the suction hood 31 and the liquid surface is no more than 150 mm.
[0030] In this embodiment, the blowing and suction type acid mist collection device 100 also includes a first supporting structure 34 and a second supporting structure 55. The first supporting structure 34 is used to fix the suction hood 31 and / or the suction pipeline 36, and the second supporting structure 55 is used to fix the blowing hood 51 and / or the blowing pipeline 56.
[0031] When the suction fan is working, the fluid direction of the suction pipe 36 is as shown by the arrow F1, so that harmful mists such as acid mist volatilized from the electroplating tank 10 are sucked away through the suction hood 31, thereby improving the safety of the open electroplating tank and helping to reduce occupational health risks.
[0032] When the blower fan is working, the fluid direction of the blower pipe 56 is shown by arrow F2, so that the harmful mist such as acid mist volatilized from the electroplating tank 10 is driven toward the suction hood 31 through the blower hood 51, further improving the safety of the open electroplating tank and helping to reduce occupational health risks. Preferably, the center position of the blower port 53 is lower than the center position of the entrance of the suction hood 31, so as to blow more harmful mist such as acid mist toward the entrance of the suction hood 31.
[0033] A first switch 37 may be provided between the suction hood 31 and the suction duct 36 to control the wind speed of the suction hood 31. Preferably, the wind speed of the air inlet 43 of the suction hood 31 is 1.5 to 3.5 m / s. Understandably, the first switch 37 may also close or open the air duct of the suction hood 31. In the case where a plurality of suction hoods 31 of a plurality of electroplating tanks 10 share the suction duct 36, the first switch 37 is particularly convenient for controlling a portion of the suction hoods 31.
[0034] Similarly, a second switch 57 may be provided between the blowing hood 51 and the blowing pipeline 56 to control the wind speed of the blowing hood 51. Preferably, the wind speed of the blowing port 53 of the blowing hood 51 is controlled at 4 to 8 m / s. Understandably, the second switch 57 may also close or open the air duct of the blowing hood 51. In the case where a plurality of blowing hoods 51 of a plurality of electroplating tanks 10 share the blowing pipeline 56, the second switch 57 is particularly convenient for controlling a portion of the blowing hoods 51.
[0035] refer to Figures 3 to 5The height H1 of the inlet of the air hood 31 is between 400 mm and 600 mm, and the width W1 is between 450 mm and 850 mm. The flow equalizer 41 is installed to the inner side of the inlet of the air hood 31 through the connector 45, and the air inlet 43 of the flow equalizer 41 is in the shape of a slit or a flat mouth. By setting the flow equalizer, the air suction capacity of the air hood 31 can be improved and the suction effect can be improved.
[0036] The flow equalizing plate 41 includes a main body 42 and a plurality of air inlets 43 formed on the main body 42. The air inlets 43 are oblong in shape, with a width W2 between 60 mm and 90 mm, and a height H2 between 15 mm and 50 mm, and more preferably, the height H2 between 15 mm and 30 mm. In the same row of air inlets 43, the spacing W3 between adjacent air inlets 43 is between 15 mm and 30 mm. The row spacing H3 between two adjacent rows of air inlets 43 is between 15 mm and 30 mm. Preferably, in two adjacent rows of air inlets 43, one row of air inlets 43 deviates by a certain distance in the horizontal direction, so that the two rows of air inlets 43 are staggered.
[0037] refer to Figure 1 and Figure 6 The blowing cover 51 includes a deformation portion 52 and a flat and long blowing portion 54, and the blowing portion 54 forms a blowing port 53. Both sides of the deformation portion 52 are connected to the outlet of the blowing pipe 56 and the blowing portion 54 respectively. The height of the deformation portion 52 gradually decreases along the direction close to the blowing port 53, and the width and height of the deformation portion 52 gradually increase along the direction close to the blowing port 53. This arrangement helps to improve the blowing effect, further improve the safety of the open electroplating tank 10, and help reduce occupational health risks.
[0038] In this embodiment, the height of the air outlet 53 is between 15 mm and 30 mm, and the width is between 450 mm and 850 mm.
