Embodiment
The utility model proposes a kind of vent cabinet of compensating ventilation cabinet.
Reference picture 1, the structural representation of the embodiment of the utility model one.
As shown in figure 1, in the utility model embodiment, the vent cabinet of the compensating ventilation cabinet includes cabinet 1, the front of cabinet 1
Provided with action pane, the surface of action pane is provided with can be in the overhead door 2 that action pane moves up and down.The inner side of overhead door 2
Provided with workbench 3, the region of the top of workbench 3 is the operating area of cabinet 1.When overhead door 2 pulls down, cabinet 1 can be reduced
The size of action pane, when overhead door 2 is pulled to minimum point, can by the operating area of cabinet 1 and cabinet exterior domain (i.e. interior) every
Open, avoid the toxic gas in operating area from leaking.
In the present embodiment, for ease of controlling the landing of overhead door 2, the top of the cabinet 1, which is provided with, to be used to control overhead door 2
The elevating mechanism 4 moved up and down.Specifically, the elevating mechanism 4 includes rotating shaft 41 and set up separately in the both ends of rotating shaft 41 and and rotating shaft
41 chains 42 being rotatably assorted.Rotating shaft 41 is arranged on the top of cabinet 1.The first end of two chains 42 is connected with overhead door 2, and two
Second end of chain 42 is connected with a balancing weight.
To keep the gas in cabinet well to circulate, the top of cabinet 1 is provided with exhaust outlet 5, in the exhaust outlet 5 and cabinet 1
Operating area communicate.Meanwhile the first intake stack of " Jiong " type 6, the upper side pipe of first intake stack 6 are set in cabinet 1
Body is located at the top of cabinet 1, and side pipe body is provided with the wind-supplying mouth 61 being arranged side by side with exhaust outlet 5 thereon.First intake stack 6
The both sides body left and right sides in the cabinet 1, and the first air inlet 62 is respectively equipped with its both sides body respectively, two first
The air holes of air inlet 62 is oppositely arranged and towards the operating area of cabinet 1.In the present embodiment, two first air inlets 62 are located at
One end of the close workbench 3 of the both sides body of first intake stack 6.So, mended from two first air inlets 62 to operating area
, can be in the convection current formed below of operating area during wind so that the gas in operating area flows up, and avoids cabinet interior air-flow disorderly
Pernicious gas is caused to escape.
Further, to avoid pernicious gas from being escaped below action pane, set in the front portion of workbench 3 provided with level
The second intake stack 7 put.The both ends of second intake stack 7 are connected with the first intake stack 6 respectively, and it is towards cabinet 1
The side of operating area be provided with the second air inlet 71.As shown in Fig. 2 the first intake stack 6 and the second intake stack 7 are formed and mended
Wind pipeline, the gas at action pane is caused to be flowed to the operating area of cabinet 1 from the benefit general mood stream of the second air inlet 71 discharge,
Pernicious gas is avoided to be escaped below action pane.As shown in figure 3, the benefit general mood stream of the second air inlet 71 also helps two
The benefit general mood stream of one air inlet 62 forms air curtain in action pane, and further blocking harmful gas escapes.
Technical solutions of the utility model are to set the first air inlet 62 at left and right sides of the inside of cabinet 1 so that in cabinet 1
Gas forms convection current, so that the gas in cabinet 1 flows to the exhaust outlet 5 of the top of cabinet 1, avoids cabinet interior air-flow disorder from making
Escaped into pernicious gas.The second air inlet 71 is set in the front of action pane, general mood stream is mended by the second air inlet 71
The gas with outside flow tendency of action pane flows into cabinet 1.The benefit general mood stream and second of two first air inlets 62
The benefit general mood stream of air inlet 71 also helps the action pane formation air curtain in cabinet 1, and blocking harmful gas escapes.
Compared with prior art, the beneficial effects of the utility model are：
1st, fresh air is directly filled into vent cabinet, without pretreatment of being heated or freezed, is reduced indoor by heating or making
The loss of cold air energy consumption；
2nd, three-dimensional three-dimensional mends general mood stream and air curtain is quickly formed at action pane, and blocking harmful gas escapes, simultaneously
Ensure the balance and stably of the interior air-flow of cabinet 1, avoid cabinet interior air-flow disorderly；
3rd, three air inlets are respectively positioned on the outer below operating area, when opening air-makeup system, mend general mood stream respectively by three
Direction enters below operating area, can ensure that testing caused pernicious gas is enclosed within benefit general mood stream, avoids to greatest extent
Pernicious gas leaks.
Preferred embodiment of the present utility model is these are only, not thereby limits the scope of the claims of the present utility model, it is every
Under inventive concept of the present utility model, the equivalent structure transformation made using the utility model specification and accompanying drawing content, or
