Abstract
The utility model relates to a kind of clean lamellar flow cover, including cover, blower, filter and return air plate, blower is set to the top of cover, and return air plate is set in the outlet of blower, and filter is set to the lower part of cover, and return air plate is located above filter.Return air plate is arranged in the outlet of the clean lamellar flow cover, blower, sprays the wind energy of blower from two sides, increases the outlet air surface of filter, form the distinguished and admirable of uniform outlet air.
Description
Technical field
The utility model relates to cleaning apparatus technical fields, more particularly to a kind of clean lamellar flow cover.
Background technique
FFU laminar flow hood is the equipment that local high-cleanness, high environment is created under low clean environment.It mainly by cabinet, efficiently
Damping layer filter presses the composition such as variable air quantity blower fan group, wind speed and pressure difference detector, illumination and microcomputer controller.Its
Working principle: drawing air at the top of FFU laminar flow hood, after passing through first, high efficiency particulate air filter with certain wind speed, forms equal layer
Stream, makes the perpendicular one-way flow of pure air, is sent out in entire outlet air surface with the wind speed average rate of 0.45m/s ± 20%, to guarantee
Reach the high-cleanness, high grade of technique requirement in working environment region.
Due to also needing that many components are arranged in cabinet, will lead to FFU blower is blown out in cabinet wind cannot uniformly from
It is sent out in filter, so that outlet air surface is small.
Utility model content
Based on this, it is necessary to which the wind blown out for FFU blower in cabinet is uneven, leads to the problem that outlet air surface is small, provides
A kind of clean lamellar flow cover.
A kind of clean lamellar flow cover, including cover, blower, filter and return air plate, the blower are set to the upper of the cover
Portion, the return air plate are set in the outlet of the blower, and the filter is set to the lower part of the cover, and the return air plate is located at
Above the filter.
There is in the middle part of the return air plate through-hole in one of the embodiments, what the return air plate was mutually separated equipped with two
Arc confining forms two air outlets between the two arc confinings.
Return air plate is arranged in the outlet of above-mentioned clean lamellar flow cover, blower, sprays the wind energy of blower from two sides, makes filter
Outlet air surface increases, and forms the distinguished and admirable of uniform outlet air.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the clean lamellar flow cover of one of embodiment；
Fig. 2 is the structural schematic diagram of the return air plate of one of embodiment.
Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this
The specific embodiment of utility model is described in detail.Many details are explained in the following description in order to abundant
Understand the utility model.But the utility model can be implemented with being much different from other way described herein, this field
Technical staff can do similar improvement without prejudice to the utility model connotation, therefore the utility model is not by following public affairs
The limitation for the specific embodiment opened.
As depicted in figs. 1 and 2, a kind of clean lamellar flow cover, including cover 1, blower 2, filter 3 and return air plate 4, blower 2
Set on the top of cover 1, return air plate 4 is set in the outlet of blower 2, and filter 3 is set to the lower part of cover 1, and return air plate 4 was located at
3 top of filter.The air intake cover 6 on 1 top of cover is fixed in the import of blower 2 by air-ducting ring 5.1 top of cover is provided with handle
7。
Return air plate 4 is arranged in the outlet of above-mentioned clean lamellar flow cover, blower 2, sprays the wind energy of blower 2 from two sides, makes to filter
The outlet air surface of device 3 increases, and forms the distinguished and admirable of uniform outlet air.
There is through-hole 41 in one of the embodiments, return air plate 4 is equipped with two arcs being mutually separated in the middle part of return air plate 4
Confining 42 forms two air outlets 43 between two arc confinings 42.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
