Description

A kind of laminar flow hood mechanism of cover plate
Technical field:
The utility model relates to the technical field of purification laminar flow hood, specifically relates to a kind of laminar flow hood mechanism of cover plate.
Background technology:
Laminar flow hood is that air by after high efficiency particulate air filter, is formed equal fluid layer with wind speed definitely, makes pure air be vertical way flow, thus ensure that in workspace the high-cleanness, high reaching technological requirement.The mounting means of laminar flow hood is mainly divided into two kinds, and suspension type is installed and console mode is installed.But be no matter the laminar flow hood of suspension type or console mode, the air inlet of laminar flow hood is all generally be arranged on the tip position of laminar flow hood, and generally all can arrange one deck screen pack, plays the effect of prefiltration.But laminar flow hood is not working time (or shelve for a long time do not work), the air inlet of laminar flow hood is arranged on the top of laminar flow hood, have some grieshoch impurity buildups unavoidably on the screen pack of air inlet, the part on screen pack even can be caused to consider hole plug, thus cause air-flow can not enter into laminar flow hood inside by this air inlet smoothly effectively filtering, and its laminar flow hood is on higher position, block the difficulty of air inlet so artificial with shelter larger.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of laminar flow hood mechanism of cover plate of new structure, make it have more value in industry.
Utility model content:
The purpose of this utility model is intended to solve prior art Problems existing, provides one to realize when laminar flow hood does not work automatically closing air inlet, and can clear up the laminar flow hood mechanism of the cover plate of the dust impurity of accumulation.
The utility model relates to a kind of laminar flow hood mechanism of cover plate, comprises case, and described case forms air inlet, and screen pack to cover on described air inlet and fixes with case, and air inlet is fixed with vertical rectangular ventilating duct;
The opening of described rectangular ventilating duct is skewed, the upper surface of described opening low side forms cover plate and installs notch, the inwall of described cover plate installation notch is hinged with rotating shaft, described rotating shaft is positioned at the cover plate that the cover plate partial fixing installed on notch is arranged with inclination, and the opening of rectangular ventilating duct can cover by described cover plate, the two ends of rotating shaft are stretched out rectangular ventilating duct respectively and are fixedly inserted with two driving bevel gears, the side of described driving bevel gear is engaged with driven bevel pinion, described driven bevel pinion is fixedly plugged with a drive link, one end of described drive link is fixedly inserted with latch segment, the two sides of cover plate form two guide rail bars, described guide rail bar parallel with the length direction of rectangular ventilating duct and with rectangular ventilating duct matched in clearance, guide rail bar is pressed against hairbrush mount pad, described hairbrush mount pad is inverted L shape, article two, the lower end of two hairbrush mount pads on guide rail bar is fixedly connected with connecting rod, described connecting rod is positioned at the below of guide rail bar and coordinates with guide rail interspace, the upper surface of hairbrush mount pad is fixedly connected with bar shaped hairbrush, described bar shaped hairbrush is across above cover plate, the brush head of bar shaped hairbrush is vertical with cover plate and contact with the upper surface of cover plate, described latch segment is pressed against on the hairbrush mount pad of bar shaped hairbrush side, the both sides of described rectangular ventilating duct are provided with two dirt-collecting box, and described two dirt-collecting box are separately positioned on the side of rotating shaft and the side of latch segment.
By technique scheme, the utility model is a kind of laminar flow hood mechanism with cover plate, it is mainly provided with one at the air inlet of laminar flow hood can realize automatically closed mechanism, screen pack is arranged in automatically closed mechanism, thus when avoiding laminar flow hood not work dust impurity buildups on screen pack.Time initial, cover plate covers on the opening of rectangular ventilating duct, latch segment is pressed against on hairbrush mount pad and is locked on rectangular ventilating duct by cover plate, when needs use screen pack, rotate the rotating shaft on the cover plate installation notch of rectangular ventilating duct low side, axis of rotation drives driving bevel gear to rotate, the driven bevel pinion that Rotatable umbrella gear driven is engaged with rotates, driven bevel pinion drives drive rod rotation, drive link drives the latch segment being set in its other end to rotate, latch segment upwards lifts the locking removed cover plate, rotating shaft simultaneously drives cover plate upwards to rotate the unlatching realizing rectangular ventilating duct around the one end be set in rotating shaft, in the process, hairbrush mount pad and connecting rod slide along guide rail bar to the other end of cover plate, dust impurity on cover plate is cleared up in the dirt-collecting box of rotating shaft side by the brush head of the hairbrush of bar shaped simultaneously, after cover plate is opened completely, bar shaped hairbrush is in the high-end of rectangular ventilating duct under the effect of cover plate, when rectangular ventilating duct closes by needs, rotate backward rotating shaft, cover plate rotates around the one end being set in rotating shaft, bar shaped hairbrush on the guide rail bar of cover plate, hairbrush mount pad and connecting rod are slipped to initial position along with Action of Gravity Field, the dust impurity of lid surface is cleared up in the dirt-collecting box of latch segment side by bar shaped hairbrush again in the process, when cover plate covers again on the opening of rectangular ventilating duct, power is delivered on latch segment by rotating shaft again, and latch segment rotates again to be pressed against on hairbrush mount pad and locked by cover plate.
By such scheme, the utility model can realize when laminar flow hood does not work automatically closing air inlet, and bar shaped hairbrush all can be utilized to clear up the dust impurity of lid surface accumulation when cover plate opening and closing, structure is simple, reliable simultaneously.
