Description
Technical field:
The present invention relates to the technical field of purification laminar flow hood, specifically relate to a kind of laminar flow hood mechanism of improvement.
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.
Summary of the invention:
Object of the present invention is intended to solve prior art Problems existing, and can close air inlet when providing a kind of laminar flow hood not work, the openings of sizes of air inlet is adjustable, and can clear up the laminar flow hood mechanism of the improvement of the dust impurity of accumulation.
The present invention relates to a kind of laminar flow hood mechanism of improvement, comprise case, described case forms air inlet, screen pack to cover on described air inlet and fixes with case, and air inlet is fixed with vertical rectangular ventilating duct;
Described rectangular ventilating duct is pressed against the cover plate of rectangle, the both sides of rectangular ventilating duct are stretched out in the both sides of described cover plate width, the both sides of cover plate width form main moving part straight down and secondary moving part, described main moving part sleeve is screwed onto on a screw rod, one end of described screw rod passes main moving part, the lower end of described secondary moving part is hinged with road wheel, described road wheel is pressed against on a moving guide rail, described moving guide rail comprises base and is molded over the gathering sill of described base upper surface, road wheel to be arranged in described gathering sill and to move along gathering sill, the lower end inner wall of gathering sill forms some equally distributed limited impressions,
The case of the side of rectangular ventilating duct is fixed with hinged seat, the two ends of described hinged seat are fixed with a pair vertical hinge bar, the height of described hinge bar is greater than the height of cover plate, a rotating shaft is hinged with between a pair hinge bar, described rotating shaft is arranged with a Roller for sticking dust, the surface of described Roller for sticking dust is fixed with one deck viscous layer, the minimum limit of Roller for sticking dust and the upper end surface of cover plate are in same level, the cover plate of rectangular ventilating duct both sides forms the escape groove of two hinge bars, described escape groove is parallel with the length direction of cover plate.
By technique scheme, the present invention is a kind of laminar flow hood mechanism with cover plate, it is mainly provided with at the air inlet of laminar flow hood the mechanism that can realize open and close, and screen pack is arranged in this mechanism, thus when avoiding laminar flow hood not work dust impurity buildups on screen pack.When cover plate opened by needs, the screw rod of rotating plate side makes main moving part move, and the secondary moving part of cover plate opposite side is followed main moving part and is moved and then make cover plate leave the air inlet of laminar flow hood, particularly, road wheel on secondary moving part is driven and moves in the gathering sill of moving guide rail, equally distributed limited impression is provided with in gathering sill, when road wheel is displaced in each limited impression, the certain position on rectangular ventilating duct opened by cover plate, regulates the size of the air inlet of laminar flow hood thus; When cover plate closed by needs, rotating backward screw rod makes main moving part move, secondary moving part is followed main moving part and is moved and then make cover plate slowly close the air inlet of laminar flow hood, in the process, as long as the power strengthening rotating screw bolt just can make road wheel shift out limited impression and get back on gathering sill.Open air inlet at cover plate or close in the process of air inlet, Roller for sticking dust on hinged seat contacts the upper surface of cover plate all the time, Roller for sticking dust moves with cover plate and rotates under the drive of transfer roller, dust on cover plate is adsorbed by the viscous layer on Roller for sticking dust, and in cover plate moving process, escape groove on cover plate is dodged hinge bar, thus makes cover plate pass hinge bar movement smoothly, and Roller for sticking dust is rolled in lid surface.
By such scheme, the present invention can close air inlet when laminar flow hood does not work, and when cover plate is opened, the openings of sizes of the air inlet of case is adjustable, all can clear up the dust impurity of accumulation when cover plate opening and closing simultaneously, and structure is simple, reliable.
