In this system, a plurality of suction tables 30 formed so as to be the suction surface 31 and the back side surface 33 are located on the exhaust side are arranged in a line.

  In this embodiment, the horizontal suction surfaces 31 of the plurality of suction tables 30 are connected so as to have the same height, and the work surface is widely formed by the plurality of horizontal suction surfaces 31. It can be used as a work facility such as a central laboratory table, an inspection table, or a dispensing table. The horizontal suction surface 31 can be made of a stainless steel punching metal (perforated plate). In this embodiment, the horizontal suction surface 31 of one suction table 30 is provided in a cover plate shape that is divided into four.

  As shown in FIG. 1, reference numeral 20 denotes an exhaust path box, which is provided in a long box shape so as to extend from a duct connection box 11 to which the exhaust duct 10 is connected, and forms the long box shape. A side provided at the upper part of at least one side surface 21 of the long side surfaces 21 and 21 so as to be able to suck inhaled air by the suction table 30 by opening a plurality of the side surfaces 21 aligned in the longitudinal direction of the long side surface 21 An air inlet 25 is provided.

  As shown in FIGS. 2 and 6, the suction table 30 is connected to the side intake port 25 on the back side surface 33 side, and the side intake port 25 is lower than the horizontal suction surface 31 in the height direction. It is connected so that it may be located and contained.

  According to this, the number of the exhaust ducts 10 can be reduced, and even if the number of the exhaust ducts 10 is reduced, the plurality of suction tables 30 can be arranged so that the exhaust is performed in a well-balanced manner. There is a special advantageous effect that the limitation of the use space can be eliminated as much as possible. That is, since the number of the exhaust ducts 10 is reduced and the side intake ports 25 are enclosed by the suction table 30, a shelf (reagent shelf or the like) is provided on the upper surface constituting the work surface of the suction table 30, as shown in FIG. ) And the degree of freedom of arrangement with respect to the table-mounted object 60 such as a working device. Further, at least the number of the exhaust ducts 10 is reduced, so that the view on the suction table 30 is improved. As shown in FIG. Communication between people becomes easier. According to this, not only is it easy to use as a work facility, but there is also an advantage that, for example, it is possible to make the facility easy to instruct students by an instructor in an educational setting.

  Moreover, in this embodiment, the exhaust path box 20 is provided by connecting a plurality of exhaust path box units 20A, 20B. 1-3, the exhaust path box 20 is provided by connecting two exhaust path box units 20A and 20B in the longitudinal direction. Thus, the exhaust path box 20 is configured, so that a large work table can be reasonably assembled.

  In this embodiment, the exhaust path box unit 20A directly connected to the duct connection box 11 is configured such that the suction table 30 is connected only to the side surface 21 on one side. The exhaust path box unit 20B connected so as to extend to 20A is configured such that the suction table 30 is connected to the side surfaces 21 on both sides. In addition, it is not limited to this form, The arrangement | positioning by which the suction table 30 is connected to the exhaust path box 20, and the arrangement | positioning of the side inlet port 25 provided in the side surface 21 for the arrangement | positioning can be set suitably. Of course.

  Moreover, in the example shown in FIGS. 1-3, although the two exhaust path box units and the four tables including the three suction tables 30 are faced and connected, the work surface is formed. Of course, the invention is not limited to this, and more can be connected. From the balance with the size of the exhaust path that can achieve the required ventilation of the exhaust path box 20, for example, six exhaust path box units 20A, 20B,... Up to the size formed by connecting the terminals is a normal form, but theoretically, the number of connected terminals is not limited.

  In the present embodiment, notches 34c on the bottom side of the bottom surface of the suction table 30 are fitted to the upper portions of the exhaust path box units 20A and 20B, and stepped shapes formed on both sides of the exhaust path box units 20A and 20B. The shoulder 23 is received in a state where the bottom side corners 34b on both sides of the suction table 30 are placed, so that the upper surface of the suction table 30 covers the upper portions of the exhaust path box units 20A and 20B. It is in a connected form.

  Further, in the present embodiment, as shown in FIGS. 1 and 4, an intake air amount adjuster 40 that can vary the opening degree of the side air intake 25 is attached to each of the plurality of side air intakes 25. As shown in FIG. 4, the intake air amount adjuster 40 according to this embodiment includes a plurality of slit-shaped openings and a fixed shutter configured in a long frame shape so as to cover the plurality of side intake ports 25. The frame 41 is provided with a plurality of slit-shaped openings and is individually provided corresponding to each side air inlet 25 and can be slid in the lateral direction so as to adjust the openings in a state of being overlapped with the fixed shutter frame 41. A movable shutter plate 42, a rectifying mesh 43 that is individually provided corresponding to each side air inlet 25 and serves as a resistance of air to be ventilated so as to make the air flow more uniform, and the rectifying mesh And a mesh fixing frame 44 provided so as to fix 43 to the back surface of the fixed shutter frame 41.

  According to the intake air amount adjuster 40, the operated portion 42a formed by projecting from the upper portion of the movable shutter plate 42 is formed on the back side of the upper surface of the main body 34 so as to correspond to the side intake port 25. It is comprised so that it can operate from the hole 34a. By adjusting the degree of overlap between the slit-shaped opening of the fixed shutter frame 41 and the slit-shaped opening of the movable shutter plate 42 by the operation relating to the sliding displacement of the movable shutter plate 42, the respective side intake ports 25 are adjusted. Each time, the air intake can be adjusted by changing the air permeability.

  As an adjustment method by the intake air amount adjuster 40, for example, the closer to the duct connection box 11, the smaller the opening degree due to the overlap between the slit-shaped opening of the fixed shutter frame 41 and the slit-shaped opening of the movable shutter plate 42. The narrower and farther the duct connection box 11 is, the larger the opening degree is, so that the air can be more uniformly sucked and exhausted by the suction tables 30. In addition, the degree of opening can be locally adjusted, and according to this, it becomes possible to suck contaminated air as necessary.

  Furthermore, in this embodiment, the air is sucked more uniformly on the entire surface of the horizontal suction surface 31 and is formed by a plurality of rectifying plates so that the air can be sent in a rectified state toward the back side 33. The rectifying plate unit 50 is disposed in the air supply space 32 inside the suction table 30. That is, on the horizontal suction surface 31, for example, air contaminated by vaporization of an organic solvent such as formalin or xylene can be sucked into the lower air supply space 32, and the suction wind speed can approach the constant speed suction. In addition, a current plate unit 50 is disposed.

  In the rectifying plate unit 50 of the present embodiment, a plurality of rectifying plate members are formed in a layered manner with a predetermined interval therebetween, and the plurality of rectifying plate members are arranged on the upper side as shown in FIG. The length of the front and rear direction is shorter and the ends are aligned in a stepwise manner, and the distance between the rectifying plates is narrower as the distance is higher. Thus, although it is stepwise, the air is sucked more uniformly over the entire horizontal suction surface 31 of the suction table 30. The suction wind speed at the horizontal suction surface 31 of the suction table 30 may be set as appropriate, for example, the control wind speed is 0.5 m / sec or more.

  According to this, in addition to the suction at the horizontal suction surface 31 of the suction table 30 being made more uniform due to the effect of the rectifying plate unit 50, the exhaust path box is passed by passing through the intake air amount adjuster 40 described above. The air is sent to 20 in a more uniform and rectified state, and is sucked from the suction table 30 to the exhaust duct 10 via the exhaust path box 20 and the duct connection box 11 by these two rectifying means, and is blown by a blower (not shown). , Contaminated air can be exhausted in a well-balanced manner.

Note that an ideal flow having a low airflow resistance of the sucked air includes a descending laminar flow on the horizontal suction surface 31, a first horizontal laminar flow orthogonal to the descending flow in the air supply space 32, and an exhaust path box. This is a second horizontal laminar flow that is orthogonal to the first horizontal flow within 20 and is supported by the two rectifying means described above.

Reference numeral 34d denotes a drain trap, which is a portion that allows solid waste to be filtered and captured to allow drainage to flow out. Further, water supply means such as a mixing tap (not shown) can be appropriately disposed on the upper frame portion of the main body 34.
According to this, there is a great advantage that the dirt on the suction table 30 can be washed away, and it becomes easy to perform a cleaning operation for keeping the suction table 30 clean.

  Further, in the present embodiment, a plate 35 provided in a plate shape having water permeability at a predetermined interval from the bottom surface of the air supply space 32 of the main body 34 formed in a sink shape is horizontally disposed. As shown in the figure, on the back surface of the eye plate 35, a leg portion 36 having a height adjusting function, and a side abutting tool 37 that abuts on the inner side surface of the sink-like member so as to be able to come into contact with and separable to prevent lateral shaking. Is provided. In addition, this eye plate 35 can be comprised with the punching metal (perforated plate) of stainless steel, for example.

  The leg portion 36 with the height adjusting function of the present embodiment is configured such that the length can be adjusted according to the degree of screwing. According to the leg portion 36 with the height adjusting function, it is provided on the side of the eye plate 35 without being provided on the body body 34 side formed in a sink shape, and the level of the eye plate 35 can be easily adjusted. Since it can be adjusted, the main body 34 can be cleaned appropriately and easily, and the current plate unit 50 can be appropriately disposed.

  Further, the side contact tool 37 of the present embodiment is not provided on the body body 34 side formed in a sink shape, and as shown in FIG. The abutting piece 37a formed on the top plate 35 is provided so as to be fastened and fixed with a screw so as to be able to be rotated and displaced so that the length of protrusion from the edge of the eye plate 35 can be adjusted.
