Abstract
The utility model discloses a kind of asphalt storage venthole, including main pipeline, main pipeline bottom mounting flanges, bottom plate and top cover are provided at the top of main pipeline, bottom plate and top cover are bolted, and the opening between bottom plate and main pipeline is equipped with Air Filter, and bottom plate is equipped with ball valve.The utility model is structurally reasonable, and Air Filter is arranged, increases the memory space of oil gas condensation, prevents greasy dirt and dust obstructing air holes, and pollution discharge structure is arranged, convenient periodically to clear up greasy dirt dust.
Description
Technical field
The utility model relates to a kind of asphalt storage ventholes.
Background technique
Asphalt storage is due to the characteristic of storage medium, and level of building fire risk is third class, and storage tank ventilation is generally by commonly leading to
Stomata realizes only have simple dust-proof, anti-foreign matter function by bend pipe.But since pitch can also discharge during storage
Glance coal and using BaP as the cycloalkane of representative out, escaping gas condenses at venthole, is made due to that can not collect condensed oil-gas
It is difficult to clear up at Air Filter blocking or tank deck greasy dirt, if maintenance be easy to cause tank body not in time, pumping such as suppresses at the accidents.
Utility model content
The utility model relates to a kind of asphalt storage venthole, dust obstruction venthole can be avoided, while can facilitate
The timely cleaning of greasy dirt.
For this purpose, structure used by the utility model is: a kind of asphalt storage venthole, including supervisor
Bottom plate is arranged in road, main pipeline bottom mounting flange, main pipeline top surrounding, and the bottom plate is circular ring shape disk body, inner ring
Equipped with convex block, main pipeline top outer connects a downward opening annular groove, between annular groove edge and the convex block of bottom plate inner ring
It is provided with Air Filter, top cover is provided at the top of main pipeline, is bolted between top cover and bottom plate.
The longitudinal section of the top cover is trapezoidal.
Ball valve is provided on the bottom plate, the ball valve is located at the bottom horizontal position of bottom plate.
Sealing ring is equipped between the bottom plate and top cover.
The beneficial effect is that: the utility model is structurally reasonable, and Air Filter is arranged, increases the memory space of oil gas condensation,
Greasy dirt and dust obstructing air holes are prevented, and pollution discharge structure is set, it is convenient that periodically greasy dirt dust is cleared up.
Detailed description of the invention
The utility model will illustrate by example and with reference to the appended drawing, in which:
Fig. 1 is the utility model sectional structure chart.
