Abstract
The utility model discloses a ventilated case used in a laboratory, comprising an upper plenum chamber and a middle control chamber. Wherein, the plenum chamber is directly communicated with an exhaust fan. The exhaust outlet of the exhaust fan is connected with an external connection exhaust duct. The lower part of a workshop is connected with an air inlet chamber. A harmful trap is arranged between the plenum chamber and the control chamber. A guiding grid opening is arranged on a manipulation platform that is positioned between the control chamber and the air inlet chamber. The side of the air inlet chamber is provided with an inlet opening. The front of the control chamber is provided with an observation door that can be pushed and drawn in horizontal direction. The ventilated case has simple structure and is easy to be constructed. The ventilated case can save 90 percent of time for design and construction. When used, the ventilated case can save heat or cold energy of 800 to 5600W. The observation door that can be pushed and drawn in horizontal direction is easy to be adjusted, which does not cause air eddy and prevents the harmful gas from escaping, thus ensuring the health of staff and effectively protecting atmospheric environment.
Description
(1) technical field:
The utility model relates to a kind of exhaust equipment, relates in particular to the laboratory hood that a kind of laboratory is used.
(2) background technology:
At present, the laboratory hood basic structure that the laboratory is used comprises operating room and collection chamber, and the operating room is fixedly mounted on the workbench.Be equipped with exhaust duct system, exhaust blower, air draft machine room etc. in the engineering design again and constitute the laboratory exhaust system, be used for getting rid of the pernicious gas that the laboratory chemical test produces, there is following problem in this class exhaust equipment:
1, because the operational observations door is unique air inlet of laboratory hood, and this air inlet is taken away indoor heat winter, takes away the refrigerating capacity of air-conditioning summer, has caused the very big waste of the energy, especially in the winter time, the staff is in all the time in the poor environment of cold wind mouth and endures cold.
2, the shared typhoon machine of many cabinets, in the work because before experiment operator stands on actuating doors, blocked when having more than one in several cabinets that an air inlet of about 40% or a typhoon machine born because of work shutoff operation door not, the face wind speed of other laboratory hood actuating doors will increase, the indoor air flow of working this moment will produce eddy current, the pernicious gas that a part produces in experiment is gone out operation outdoors by the eddy current winding, polluted staff's breathing zone air, the serious harm staff is healthy.
3, exhaust blower separates with laboratory hood in the exhaust system of being made up of laboratory hood, generally is the blower fan of all exhaust systems of laboratory to be focused on unified layout of air draft machine room of roof special use, and is furnished with a large amount of airducts and connects laboratory hood and blower fan.Concentrated the motor of more blower fan and blower fan adapted because of Ventilator Room, so also need consider the damping on the isolation of noise and blower fan, motor basis, prevent from precision instrument is produced harmful effect, Ventilator Room and the pipe layers that gathers airduct also must take the construction area of some, these problems bring workload big all for design and construction, the difficulty of technical sophistication.
4, laboratory hood can only be collected pernicious gas and be discharged in the atmosphere and go, and can not handle, and therefore causes the severe contamination to atmospheric environment.
(3) summary of the invention:
In order to overcome the above-mentioned shortcoming that existing laboratory hood exists, it is a kind of simple in structure that the utility model provides, small investment, the laboratory hood that helps the healthy and atmospheric environment of staff that can handle pernicious gas.
The utility model is realized in the following manner: a kind of laboratory hood, it comprises the plenum chamber on top, the operating room at middle part, wherein, plenum chamber directly is communicated with exhaust blower, the exhaust blower exhaust outlet is connected with external exhaust duct, the below, operating room is connected with new wind inlet air plenum, between plenum chamber and operating room, be provided with the pernicious gas capturing device, operating desk between operating room and the new wind inlet air plenum is provided with guiding cloth air port, new wind inlet air plenum side is provided with air inlet, and the operating room front is provided with the plug-type operational observations door of level.
Exhaust blower is located in the plenum chamber.
In operating room, also be provided with deflector, fluorescent lamp.
New wind inlet air plenum is separated into anterior article cabinet, the surge tank at rear portion, and air inlet communicates with surge tank.
The pernicious gas capturing device is the pernicious gas trapping layer, and the pernicious gas trapping layer is supported by following grid; The plug-type operational observations door of level is divided into left, center, right three fan doors.
Electric control panel is fixed on the operating room front; New wind inlet air plenum one side is provided with air inlet;
New wind inlet air plenum both sides are provided with air inlet.
Good effect of the present utility model is:
1, simple in structure, easy construction, because exhaust blower and laboratory hood constitute one, it is integrated to make formula huge and exhaust system that disperse in laboratory existing " laboratory hood---long air channel---air draft machine room " change single cabinet into, thereby simplified construction working greatly, can save for 90% design and construction man-hour.
2, owing to draft capacity in the laboratory only is the 10-30% of existing laboratory hood type, so every cabinet can be saved hot and cold energy 800-5600W when moving.
3, outdoor new wind is in an organized way sent in the operating room by blast pipe, surge tank and operation tablecloth air port, in the operating room air current composition be by the cloth air port operational observations door place form from bottom to top high velocity air and table top two side direction table tops in the middle of tiltedly on the focused airflow of 45 ° of directions pernicious gas is led, guarantee that pernicious gas does not overflow from the operational observations door; The adjustment of the plug-type operational observations door of level is flexible, has guaranteed that operating personnel do not hinder a grade operational observations door, therefore can not cause air-swirl, has guaranteed staff's health requirements.
4, the work indoor harmful gas is handled the back through pernicious gas capturing device in the plenum chamber and is discharged in the outside atmosphere by exhaust blower in the plenum chamber, thereby has guaranteed the protection to atmospheric environment.
The utility model is described in further detail below in conjunction with accompanying drawing:
