' Int. Cl. B01d 46/02 US. Cl. 55-472 1 Claim ABSTRACT OF THE DISCLOSURE A laboratory bench assembly including a bench table mounted on a pedestal and having a dust-collector mechanism located in the pedestal with the ducts leading to the dust collector concealed in the bench table. A dust-collecting hood may be located in a drawer of said bench table and provided with a telescoping slip joint to permit the drawer to be opened and closed.
SUMMARY OF THE INVENTION This invention is concerned with a laboratory bench assembly and more specifically with such an assembly having a concealed, built-in dust collector.
An object of this invention is a laboratory bench assembly in which a dust-collecting system is concealed in the pedestal thereof.
Another object is a laboratory bench assembly having a built-in dust-collecting system in which the dust-collecting ducts are concealed in the bench table portion thereof.
Another object is a laboratory bench assembly having a dust-collecting hood mounted in a drawer of the bench table portion thereof with the dust hood arranged to move in and out of the table assembly with the drawer.
Another object is a laboratory bench having a built-in dust collector in which the dust and particle-laden air passing through the dust collector is required to make three 180 turns.
Another object is a laboratory bench assembly having a built-in dust collector in which the blower is located beneath and to one side of the bag filter unit for ease of installation.
Other objects will be found in the following specification, claim and drawings.
BRIEF DESCRIPTION OF THE DRAWINGS The invention is illustrated more or less diagrammatically in the following drawings wherein:
FIG. 1 is a perspective view of a laboratory bench assembly of this invention with some parts shown by broken lines;
FIG. 2 is a perspective view of the pedestal of the bench assembly of FIG. 1 showing the components of the dust collector; and
FIG. 3 is a partial side elevational view of the drawer shown in FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings and Particularly to FIG. 1 thereof, the numeral 11..indicates the laboratory bench assembly of this invention. This bench assembly includes a pedestal 13 on top of which is mounted a bench table 15. Bench tops 17 are positioned on the bench table and are separated by a service shelf housing 19. A service shelf 21 is mounted on the housing 19.
The pedestal .13 includes side walls 25 and 27 and end walls 29 and 31. The pedestal also has a bottom wall 33 and a top wall 35. (FIG. 2). A removable panel 37 is provided in the side wall 2.5 of the pedestal. Suitable gaskets may be provided for the panel but are omitted in the drawings.
The bench table 115 has a side wall 41 with openings to receive drawers. One of the openings 43 receives an upper drawer 45 and a lower drawer47. An open-top grinding hood 49 is located in lower drawer 47. A duct 51 leading to the hood telescopes inside a larger exhaust duct 53 located in the bench table. The exhaust duct 53 leads to an inlet opening 57 in the top wall 35 of the pedestal.
A second inlet opening '59 in the top wall 35 of the pedestal 13 is connected to a duct 61 which extends through the service shelf housing 19 to an opening 63 in a side wall 65 of the service shelf housing. An exhaust hood such as a fishmouth 67 connects to the opening 63 and extends over the bench top 17. It should be understood that suitable flexible hose may be substituted for V the ducts 53 and 61.
A vertical partition 71 is located in the pedestal inwardly of the inlet openings '57 and 59. This partition extends a short distance downwardly from the top wall 35. A second vertical partition 73, parallel to and spaced from partition 71, extends from the bottom wall 33 of the pedestal and terminates below the top wall 35 thereof. A horizontal partition 75 extends between the partitions 71 and 73. An opening 77 is formed in the horizontal partition. L-shaped brackets 79 are attached to the underside of the partition 75 outwardly of the opening 77 to receive a filter frame '81 supporting bag filters 83. It should be noted that the L-shaped bracket attached to partition 71 may be formed as an integral part of the partition in the manner shown in FIG. 2. A member is located at the edge of partition 73 adjacent the side wall 25 for additional support of the panel 37.
A blower 87 driven by an electric motor 89 is mounted in the pedestal 13 between the partition 73 and the end wall 31. The blower is located below the opening 77 in the filter frame. The blower discharges to a silencer chamber 91 which may be lined with sound-absorbing insulation (not shown). Sound-absorbing insulation may also be installed on the walls and partition surrounding the blower, but is not shown. Discharge openings 93 and 95 lead from the silencer box. These openings may be connected by ducts or suitable flexible hose (not shown) to exhaust vent 97 in the service shelf 21 or exhaust vent 99 in the end wall .101 of the service shelf housing 19. Alternately, the filtered air may exhaust beneath the bench table.
An electric or manually operated vibrator may be attached to the filter bag unit to shake ofi accumulated dust. However, for clarity of illustration, this has not been shown. As shown in FIG. 1, gas and air valves and electric receptacles may extend through openings in the wall 65 of the service shelf housing 19. The conduits and pipes for these utilities may pass through the pedestal and bench table but are omitted for clarity of illustration.
The use, operation and function of this invention are as follows:
Dust and particles from grinding operations may be drawn into the ducts 53 and 61 through the exhaust hoods 49 and 67, respectively. The dust and particle laden air will follow the path indicated by the arrows in FIG. 2. The dust and particles will be intercepted and deposited on the outside surfaces of the bag filters 83. The clean air will pass through the filters, flow over the partition 73, through the blower '87 and into the silencer box 91. From the silencer box the air will be discharged through the exhaust outlets 93 and 95. In flowing through the pedestal, the air will make three turns with the turns aiding in the removal of dust and fine particles from the air.
The open top dust hood or grinding hood 49 can be used by opening the drawer 47. When the drawer is closed, the duct 51 telescopes into the duct 53. The bag filters may be removed by removing the front panel 37 and sliding the bag filters and their filter frame 81 out of the L-shaped brackets 79 through the opening in the side wall 25 of the pedestal. With the panel 37 removed, particles and dust may be cleaned out of the bottom of the pedestal.
Whereas the adaption of this invention to one form of laboratory bench assembly has been shown and described, it should be understood that this showing is illustrative only and the invention may be adapted to other forms of laboratory bench assemblies.
What is claimed is:
1. A laboratory bench assembly including:
a pedestal housing,
a bench table including a side and top wall mounted on the top of said pedestal housing,
a dust collector located in the pedestal housing,
at least one duct connected to the pedestal housing leading to said dust collector with said duct extending through said bench table,
at least one drawer provided in said bench table extending through the side wall, and
a grinding hood located in said drawer including a conduit which is connected to said duct by means of a telescoping slip joint and suction means for causing air to flow through said grinding hood and dust collector.
