Description
Technical Field
The utility model relates to a fume chamber's wind-guiding workstation belongs to experimental facilities technical field.
Background
The fume hood is common equipment in a laboratory and is used for removing harmful gas generated in the experimental process; the workstation of current fume chamber is planar structure mostly, and the distribution of the inlet end air current of this kind of structure is even reasonable inadequately to can form the air current vortex in the corner of the end of giving vent to anger, influence the exhaust.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an air guide workbench of fume chamber in order to overcome the not enough of prior art.
In order to achieve the above purpose, the utility model adopts the technical scheme that: an air guide workbench of a fume hood comprises a cabinet body and a table board, wherein the table board is arranged in the cabinet body, an air inlet of the cabinet body is positioned at the front end of the table board, and an air outlet of the cabinet body is positioned above the rear end of the table board; the middle part of the table top is used for placing an experiment table frame, the front end of the table top is provided with a front wind guide protruding part, and the front wind guide protruding part is higher than the middle part of the table top; the rear end of the table top is provided with a rear air guiding slope which is formed by gradually rising from the middle part of the table top to the inner wall of the rear side of the cabinet body.
Preferably, the bottom of the front end of the table top is provided with a front ventilation groove, the front end of the table top is also provided with a front air supplement channel, and the front ventilation groove delivers air to the rear side of the front air guide protruding part through the front air supplement channel.
Preferably, the bottom of the rear end of the table top is provided with a rear ventilation groove, the rear end of the table top is also provided with a rear air supply channel, and the rear ventilation groove supplies air to the upper side of the rear air guide slope through the rear air supply channel.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the wind guide workbench of the ventilation cabinet in the scheme of the utility model is provided with the front wind guide bulge part on the table board, so that the air flow distribution at the air inlet end is uniform and reasonable; and designed back wind-guiding slope, avoided giving vent to anger the corner of end and formed the air current vortex, guaranteed the exhaust effect, whole ventilation effect that makes the fume chamber more can satisfy the requirement in laboratory.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
fig. 1 is a schematic view of an air guide workbench of a fume chamber.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a fume chamber's wind-guiding workstation, contain the cabinet body 1 and mesa 2, mesa 2 sets up in the cabinet body 1, and the air intake of the cabinet body 1 is located the front end of mesa 2, and the air outlet of the cabinet body 1 is located the rear end top of mesa 2, and the middle part of mesa 2 is used for placing experiment rack 3.
The front end of the table board 2 is provided with a front air guide protruding part 4, the front air guide protruding part 4 is higher than the middle part of the table board 2, so that air flow on the air inlet side is distributed more uniformly, and more air flow flows to the experiment table rack 3 and the upper side in the cabinet body; the front end bottom of mesa 2 is provided with preceding air groove 6, and the front end of mesa 2 still is provided with preceding air supply channel 7, and preceding air groove 6 is through preceding air supply channel 7 with the air current to the rear side of preceding wind bellying 4, reinforcement mesa 2's surface air current.
The rear end of the table board 2 is provided with a rear air guiding slope 5, the rear air guiding slope 5 is formed by gradually rising from the middle part of the table board 2 backwards and extending to the inner wall of the rear side of the cabinet body 1, and airflow vortex is prevented from being formed at corners; the rear end bottom of mesa 2 is provided with back air channel 8, and the rear end of mesa 2 still is provided with back air supply channel 9, and back air channel 8 is sent the air current to the upside of back wind-guiding slope 5 through back air supply channel 9, supplementary promotion air current rising discharge fume chamber.
Arrows in the figure are schematic in the direction of air flow, the front air supplement channel 7 and the rear air supplement channel 9 are dense elongated hole structures arranged side by side at equal intervals to ensure the coverage and uniformity of air supplement, and the side by side direction is perpendicular to the paper surface of the figure.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
