Description
Technical field
The utility model relates to experimental facilities field, relates in particular to a kind of laboratory exhaust apparatus.
Background technology
Laboratory ventilation is an indispensable part in lab design.In order to prevent that laboratory worker from sucking or swallowing chemical substance and the organism into some are poisonous, that can cause a disease or toxicity is not clear, and in order to stop the absorption of some steam, gas and particulate (smog, coal smoke, dust and aerosol), in laboratory, should have good ventilation, the method for available vent cabinet, ventilator cowling or local ventilation is removed.Laboratory ventilation is an indispensable part in lab design.In order to prevent that laboratory worker from sucking or swallowing chemical substance and the organism into some are poisonous, that can cause a disease or toxicity is not clear, and in order to stop the absorption of some steam, gas and particulate (smog, coal smoke, dust and aerosol), in laboratory, should have good ventilation, the method for available vent cabinet, ventilator cowling or local ventilation is removed.In the chemical experiment of carrying out in big-and-middle universities and colleges, often can produce various pernicious gases, and conventionally carry out this type of experiment, mostly be Yi Ge class or a plurality of class and mix and carry out, large contingent, like this with regard to the good ventilating system of exigence more.Existing chemical laboratory ventilating system connects each exhaust hood mouth, due to far and near different apart from air draft main pipeline, has caused exhaust air rate inhomogeneous.The ventilator cowling adopting is all one conventionally, when changing laboratory table, just need to move by needs while adjusting, and very inconvenience, ventilator cowling can only be fixed on experimental bench unwanted time simultaneously, the waste limited space of experimental bench.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of laboratory exhaust apparatus.
The utility model is to be achieved through the following technical solutions:
A kind of laboratory exhaust apparatus, comprise laboratory table, be arranged on the wireway of laboratory table inside, lay the ground of laboratory table, be embedded in the appendix of ground, the tracheae surface at the air inlet place of described appendix is provided with sealant, the air inlet place of the wireway of described laboratory table is provided with suspended hood, on described suspended hood, is fixed with block, and the edge of the groove of described laboratory table is hinged with cover plate.
As optimal technical scheme of the present utility model, the top of described air inlet is higher than the upper surface of ground.
As optimal technical scheme of the present utility model, the material of described sealant is rubber.
As optimal technical scheme of the present utility model, being shaped as of described block is cylindrical.
Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, simple in structure, adopt segmented combining structure, by socket each other, combine, easy for installation, when needed suspended hood is installed, while not needing to use, taken out and put well specially, cover plate is covered and formed complete experiment porch, save the space of experimental bench, reduced falling into of dust, also reduced the waste of energy simultaneously, experimental bench is easy to adjust, and good sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-appendix; 2-sealant; 3-laboratory table; 4-cover plate; 5-block; 6-suspended hood; 7-wireway; 8-ground; 10-air inlet.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of laboratory exhaust apparatus, comprise laboratory table 3, be arranged on the wireway 7 of laboratory table 3 inside, lay the ground 8 of laboratory table 3, be embedded in the appendix 1 of ground 8, the tracheae surface at air inlet 10 places of described appendix 1 is provided with sealant 2, the material of described sealant 2 is rubber, good seal performance, the top of described air inlet 10 is higher than the upper surface of ground 8, later just in time can being socketed in wireway 7 of air inlet 10 is installed, the sealing function that sealant 2 plays, can reach good sealing effectiveness.
The air inlet place of the wireway 7 of described laboratory table 3 is provided with suspended hood 6, and suspended hood 6 is arranged on wireway 7 in use, and the used time does not take off, and puts well specially easy and simple to handle.Be placed on described suspended hood 6 and be fixed with block 5, being shaped as of described block 5 is cylindrical, and when suspended hood 6 is sleeved on to the inside of wireway 7, block 5 has stopped that suspended hood 6 moves downward.The edge of the groove of described laboratory table 3 is hinged with cover plate 4, and cover plate 4 is opened, and suspended hood 6 inserts wireway 7 can realize air draft, while not needing, cover plate 4 is closed and has played sealing function, has reduced the quantity of air inlet, has increased the suction of other air inlet.
The utility model is reasonable in design, simple in structure, adopts segmented combining structure, by socket each other, combine, easy for installation, when needed suspended hood is installed, while not needing to use, take out and put well specially, cover plate is covered and formed complete experiment porch, save the space of experimental bench, reduced falling into of dust, also reduced the waste of energy, experimental bench is easy to adjust, and good sealing effect simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
