Abstract
The utility model relates to a mist discharging cover of a planishing mill, which comprises a cover body (1). The cover body (1) is distributed around the stander of the planishing mill; the band steel inlet side of the cover body (1) is provided with a first wind pipe port (3), and a first port flange is arranged at the first wind pipe port (3); the band steel outlet side of the cover body (1) is provided with a second wind pipe port (6), and a second port flange is arranged at the second wind pipe port (6). The mist discharging cover is characterized in that the band steel inlet side of the cover body (1) is provided with a first pump air flue (7) which is communicated with the first wind pipe port (3); an air draft gap (9) is arranged on the first pump air flue (7) above the passing part of the band steel; the band steel outlet side of the cover body (1) is provided with a second pump air flue (8) which is communicated with the second wind pipe port (6); an air draft gap (9) is arranged on the second pump air flue (8) above the passing part of the band steel. The mist discharging cover has the advantages of good mist discharging effect.
Description
Technical field
The utility model relates to a kind of mist exhausting cover of planisher.
Background technology
The cold rolling levelling machine has the smooth and wet smooth two kinds of smooth patterns of doing, and smoothly can obtain better plate face quality and wet.Along with improving constantly that strip surface quality is required, increasing planisher begins to adopt wet smooth production model.When adopting wet smooth pattern smooth, need to spray smooth liquid at the inlet of frame.Because the smooth operating rate of cold rolling levelling machine is very high, can produce fog when high speed is smooth.Therefore, planisher all is furnished with the fog discharge system.The fog discharge system comprises fog discharge blower fan, mist exhausting cover, intermediate duct, valve and filter etc.Wherein the version of capacity of fog discharge blower fan (under the selected situation) and mist exhausting cover is to fog discharge influential effect maximum.
As shown in Figure 1, existing planisher mist exhausting cover comprises cover body 1, the band steel entrance side of cover body 1 is provided with first duct collar 3, first duct collar, 3 places are provided with first flange, first airduct 4 links to each other with first flange, the band steel exports side of cover body 1 is provided with second duct collar, 6, the second duct collar, 6 places and is provided with second flange, and second airduct 5 links to each other with second flange; First airduct 4, second airduct 5 link to each other with the fog discharge blower fan.The major defect of this seal bootr is: 1. cover is big, much is invalid, and fan capacity can't effectively be utilized.2. the negative pressure inequality of whole cover is difficult to reach required demeanour of effective suction and negative pressure in the working region of cover.These questionnaires are insurmountable by the ability that improves air exhauster.
Summary of the invention
The planisher mist exhausting cover that provides a kind of fog discharge effective is provided the purpose of this utility model.
To achieve these goals, the technical solution of the utility model is: the planisher mist exhausting cover, it comprises cover body, cover body is arranged in around the frame of planisher, the band steel entrance side of cover body is provided with first duct collar, the first duct collar place is provided with first flange, and the band steel exports side of cover body is provided with second duct collar, and the second duct collar place is provided with second flange; It is characterized in that: the band steel entrance side of cover body is provided with the first suction air channel, and the first suction air channel is connected with first duct collar, is positioned to be with steel to be provided with the exhausting slit by the first suction air channel of the top at position; The band steel exports side of cover body is provided with the second suction air channel, and the second suction air channel is connected with second duct collar, is positioned to be with steel to be provided with the exhausting slit by the second suction air channel of the top at position.
The beneficial effects of the utility model are: set up two suction air channels in former mist exhausting cover, be arranged in entrance side and outlet side; Be positioned at the band steel and establish the exhausting slit by the first suction air channel, second suction at position on the air channel, avoided inactive area, extend into the inside fog Production Regional of cover body, aspirate before the fog disperse, fog discharge is effective.Suction opeing on the wind pumping channle is discontinuous exhausting slit, but not the big cover of former mist exhausting cover, has improved the efficient of blower fan; The utility model has higher wind speed at the place, slit of suction, is about 4 times of former mist exhausting cover structure; Exhausting system improved greatly to the capturing ability of smog after wind speed improved, thereby had reduced leakage rate.
