Abstract
The utility model relates to a ventilation flow collecting cover capable of preventing condensed waste liquid from dripping/flowing. The ventilation flow collecting cover comprises a cover body; the lower part of the cover body is the periphery of a gas inlet; the edge of the periphery of the gas inlet is inwardly bent to form a waste liquid collection tank; and the bottom of the waste liquid collection tank is provided with a waste liquid discharge outlet. The ventilation flow collecting cover is applicable to the discharge of waste gases of a laboratory, and the condition that the condensed waste liquid is formed on a ventilation pipeline and a flow collecting cover due to high moisture content in the waste gases and is gathered at the gas inlet opening end of the flow collecting cover under the action of gravity, the dripping/flowing of the waste liquid is formed, and thus the hazard to people or instruments under the flow collecting cover is caused can be avoided. The waste liquid is collected through the waste liquid collection tank and flows to a waste liquid collection pool along a guide pipe, so that the dripping/flowing of the waste liquid of the flow collecting cover is avoided, and the safety of the people and the instruments can be effectively protected.
Description
Technical field
The utility model relates to the ventilation afflux cover of laboratory discharging waste gas, relates in particular to a kind of overhead ventilation afflux cover that discharges the corrosivity toxic and harmful.
Background technology
From the needs of laboratory discharging waste gas, the ventilation afflux cover of the overhead that is widely used.Owing to corrosive toxic harmful exhaust gas that is mostly of laboratory discharging, moisture is bigger in the waste gas, on air pipeline and afflux cover, is prone to form the condensation waste liquid, under the gravity effect, accumulates in afflux cover air inlet openings end, forms the waste liquid drip.The waste liquid drip will produce harm to people under the afflux cover or instrument.
Summary of the invention
The purpose of the utility model provides a kind of ventilation afflux cover that prevents waste liquid drip function that has.
The purpose of the utility model realizes through following technical scheme.
A kind of have a ventilation afflux cover that prevents condensation waste liquid drip, comprises cover body, and the cover body bottom is the air inlet periphery, by described air inlet periphery to concave edge, form the waste collection groove.The bottom of this waste collection groove has the waste liquid sewage draining exit.The waste liquid that the waste collection groove is collected flows to the collecting pit of waste liquid through conduit.
The utility model is simple and practical, be easy to make, and can prevent the waste liquid drip, thereby effectively protect the safety of people and instrument.
Description of drawings
Accompanying drawing is the structural representation of the utility model ventilation afflux cover.
Among the figure: 1. cover body, 2. air inlet periphery, 3. waste collection groove, 4. waste liquid sewage draining exit.
The specific embodiment
Referring to accompanying drawing, a kind of have a ventilation afflux cover that prevents condensation waste liquid drip, and its main body is a cover body 1, and cover body 1 bottom is the air inlet periphery 2 of symmetry, air inlet periphery 2 to concave edge, form waste collection groove 3.Waste collection groove 3 bottoms have waste liquid sewage draining exit 4.
Ventilation afflux cover, the geometry of appearance whatsoever, all can the periphery of air inlet openings end to concave edge, form the feeder of waste liquid.The convenience of visual discharging, the joint with endoporus is installed in perforate on the appropriate location of feeder.Big or the afflux cover is long-pending big like condensing liquid quantity, can optionally open plural discard solution discharge port.
The width of waste collection groove 3 is a, and the maximum length in cover body 1 cross section of afflux cover is of a size of D, and a/D ≈ 0.04 is to reach preferable air draft effect.
Claims (3)
1. one kind has the ventilation afflux cover that prevents condensation waste liquid drip, comprises cover body (1), and the bottom of cover body (1) is an air inlet periphery (2), it is characterized in that: described air inlet periphery (2) is to concave edge, formation waste collection groove (3).
2. according to claim 1 have a ventilation afflux cover that prevents condensation waste liquid drip, it is characterized in that: have waste liquid sewage draining exit (4) in the bottom of described waste collection groove (3).
3. according to claim 1 have a ventilation afflux cover that prevents condensation waste liquid drip, and it is characterized in that: the width of waste collection groove (3) is a, and the maximum length in the cover body of afflux cover (1) cross section is of a size of D, a/D ≈ 0.04.
