Description
Technical field：
The present invention relates to the technical field of laminar flow hood, more specifically to a kind of dust guard of laminar flow hood air inlet.
Background technology：
Laminar flow hood be by air with definitely wind speed by high efficiency particulate air filter after, form equal fluid layer, make pure air in hanging down
Straight unidirectional stream, so as to ensure that the high-cleanness, high that technological requirement is reached in workspace.The mounting means of laminar flow hood is broadly divided into two
Kind, suspension type is installed and console mode is installed.But the either laminar flow hood of suspension type or console mode, the air inlet one of laminar flow hood
As be all provided on the tip position of laminar flow hood, and typically one layer of screen pack can be all set, play the effect of initial filter.But
Laminar flow hood is not when working (or long-term shelve does not work), and the air inlet of laminar flow hood is arranged on the top of laminar flow hood, unavoidably
Have some grieshoch impurity to be deposited on the screen pack of air inlet, or even the part on screen pack can be caused to consider hole plug, so that
Cause air-flow to smoothly pass over the air inlet and enter inside laminar flow hood effectively to be filtered, and its laminar flow hood is higher
Position on, taking human as blocking the difficulty of air inlet with shelter than larger.
The content of the invention：
The purpose of the present invention and provides a kind of dust guard of laminar flow hood air inlet aiming at the deficiency of prior art,
It can realize automatic closing air inlet when laminar flow hood does not work, so that avoiding dust impurity from being deposited on screen pack causes air-flow
Have some setbacks.
To achieve the above object, the technical solution adopted by the present invention is as follows：
Air inlet, layer are formed on a kind of dust guard of laminar flow hood air inlet, including laminar flow hood, the upper surface of laminar flow hood
The air inlet of stream cover is fixed with filter, and the both sides of laminar flow hood are fixed with vertical baffle plate, and the upper end of baffle plate is triangular in shape, baffle plate
The both sides at top are against there is inclined cover plate, and the lower end of cover plate is formed forms level on vertical side plate, the side plate of cover plate
Guide groove, be plugged with T-shaped limited post in guide groove, limited post is fixed on baffle plate, and roller, roller are plugged with limited post
Side wall be resisted against on the side plate of plate, the outer wall of roller is resisted against on rack, and gear is engaged with rack, and gear is fixed on motor
Rotating shaft on, motor is fixed on electric machine support.
The length of the cover plate is more than the spacing between the side shield of air inlet two of laminar flow hood.
The cover plate is provided with two pieces, is abutted together at the top of two cover plates.
A grade bar is formed on the top of the cover plate and the side side of cover plate.
The both sides of the laminar flow hood are fixed with handle.
The beneficial effects of the present invention are：
(1), it is provided with dust guard in the air inlet of laminar flow hood, and automatic close is realized when laminar flow hood does not work so as to realize
Air inlet is closed, so as to avoid dust accretions from causing air-flow to have some setbacks in screen pack.
(2), the inclined device of the cover plate for the dust guard that it is used, and a grade bar is provided with, in ability cover plate moving process
In can reduce dust and fall on screen pack or filter.

Embodiment：
Embodiment：As shown in Fig. 1 to 4, a kind of dust guard of laminar flow hood air inlet, including laminar flow hood 1, laminar flow hood 1
Air inlet is formed on upper surface, the air inlet of laminar flow hood 1 is fixed with filter, and the both sides of laminar flow hood 1 are fixed with vertical gear
Plate 2, the upper end of baffle plate 2 is triangular in shape, and the both sides at the top of baffle plate 2 are against there is an inclined cover plate 3, and the lower end of cover plate 3 forms perpendicular
Formed on straight side plate, the side plate of cover plate 3 and T-shaped limited post 4 is plugged with horizontal guide groove 32, guide groove 32, it is spacing
Post 4 is fixed on baffle plate 2, and roller 5 is plugged with limited post 4, and the side wall of roller 5 is resisted against on the side plate of plate 3, outside roller 5
Wall is resisted against on rack 7, and gear 6 is engaged with rack 7, and gear 6 is fixed in the rotating shaft of motor 8, and motor 8 is fixed on motor branch
On frame 9.
The length of the cover plate 3 is more than the spacing between the side shield 2 of air inlet two of laminar flow hood 1.
The cover plate 3 is provided with two pieces, and the top of two cover plates 3 is abutted together.
Grade bar 31 is formed on the top of the cover plate 3 and the side side of cover plate 3.
