Above-mentioned high school chemical experiment table, active carbon is contained container and is positioned at above liquid Sheng container.
Protective cover is as on desktop, and during chemical experiment, hand is stretched in protective cover inner chamber by hand hole and carries out chemical experiment, and pernicious gas passes through the effect of blower fan sequentially through active carbon and liquid filtering, cleans.Be connected by arc bend bent plate between upper flat plate with front vertical plate, make visual effect better.Protective cover plays protective action.Protective cover is transparent, is convenient to observe.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in more detail:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial schematic diagram of Fig. 1.
Fig. 3 is the partial schematic diagram of Fig. 2.
In figure: 1 table leg, 2 desktops, 3 back vertical plates, 4 diapires, 5 front panels, 6 front vertical plates, 7 hand holes, 8 arc bend bent plates, 9 upper flat plates, 10 blower fans, 11 filter screens, 12 active carbons contain container, 13 filter screens, 14 gas outlet tubes, and 15 liquid contain container.
Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of high school chemical experiment table comprises the table leg 1 of desktop 2 and supporting desktop.Desktop is equipped with the protective cover of transparent material, protective cover comprises front vertical plate 6, back vertical plate 3, left riser, right riser and upper flat plate 9, is connected between upper flat plate with front vertical plate by arc bend bent plate 8, and the lower edge of protective cover and desktop seal.Front vertical plate is arranged at intervals with two hand holes 7 passed through for staff.Also harmful gas processing device is equipped with in protective cover, harmful gas processing device comprises active carbon and contains container 12 and liquid Sheng container 15, the opposite end that active carbon contains container is equiped with gas inlet tube and gas outlet tube respectively, the blower fan 10 that air intake active carbon in protective cover is contained in container is connected with gas inlet tube, the mouth of pipe and the liquid of gas outlet tube 14 are contained container bottom and are communicated with, and liquid is contained container top and is provided with gas vent.
High school chemical experiment table also comprises the drawer as experiment porch, drawer comprises front panel 5, diapire 4 and two sidewalls, two sidewalls arrange slide rail, accordingly, left riser and right riser arrange slide rail respectively, and drawer can move by fore-and-aft direction, and drawer front panel arranges handle, drawer is positioned at below hand hole, front vertical plate has drawer mouth.Diapire is chemistry experiment operating platform.The design of this drawer type can make experiment equipment pass in and out protective cover easily.
