Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a ventilating cap with a drainage function comprises a connecting pipe 1 and an air outlet pipe 2, a drainage screen plate 4 which is inclined downwards is arranged at the air outlet of the air outlet pipe 2, the upper end of the inner cavity of the drainage screen plate 4 is provided with a mesh 41, a condenser pipe 3 is sleeved at the joint of the connecting pipe 1 and the air outlet pipe 2, the meshes on the drainage screen plate 4 are sequentially communicated and are communicated with the inner cavity of the air outlet pipe 2, an upper screen plate 31 and a lower screen plate 32 are arranged in the condenser pipe 3, the upper screen plate 31 and the lower screen plate 32 are embedded and sleeved up and down in the inner cavity of the connecting pipe 1, a reserved gap is arranged between the opposite surfaces of the upper screen plate 31 and the lower screen plate 32, the upper screen plate 31 and the lower screen plate 32 are not contacted with the inner cavity wall of the connecting pipe 1, the bottom ends of the upper screen plate 31 and the lower screen plate 32 are in a slope shape, the diversion holes in the upper screen plate 31 and the lower screen plate 32 are distributed in a staggered way, and, the oil smoke generated when the equipment works enters the air outlet pipe 2 through the connecting pipe 1 and is then discharged through the outlet of the air outlet pipe 2, when the oil smoke passes through the condensing pipe 3, the upper mesh plate 31 and the lower mesh plate 32 cool, condense and filter the oil smoke, the formed oil drops directly flow back to the equipment through meshes on the upper mesh plate 31 and the lower mesh plate 32 along the slope-shaped bottom ends of the upper mesh plate 31 and the lower mesh plate 32, the smoke is continuously moved upwards and discharged through the air outlet pipe 2, and is filtered again through the meshes 41, the oil drops formed on the drainage mesh plate 4 flow down along the through flow guide holes in the meshes 41 and finally flow back to the equipment through the air outlet pipe 2, the oil content in the oil smoke is effectively reduced in the smoke discharging process, so that the pollution of the oil smoke discharge to the environment is reduced, when the oil smoke is filtered and condensed through the condensing pipe 3 and the lower mesh plate 32 of the upper mesh plate 31 and the lower mesh plate 32, the upper mesh plate 31 and the lower mesh plate 32 sequentially treat the smoke, the oil produced by the flue gas treatment flows along the slopes of the upper screen 31 and the lower screen 32 under the action of gravity and finally flows back to the equipment.

The working principle is as follows:

firstly, a ventilation cap composed of components such as a connecting pipe 1, an air outlet pipe 2 and the like is fixed on equipment by bolts, when the equipment runs, the temperature of lubricating oil rises to generate oil smoke, the oil smoke passes through the connecting pipe 1 and is exhausted into the atmosphere through the air outlet pipe 2 through an upper screen plate 31, a lower screen plate 32 and a condenser pipe 3, the oil smoke has certain cooling and condensing effects after passing through the pipe walls of the upper screen plate 31, the lower screen plate 32 and the condenser pipe 3 every time, oil mist in the oil smoke is condensed into oil drops, and the oil drops flow back into the equipment along the slope-shaped bottom end of the upper screen plate 31 and the lower screen plate 32;

the smoke continuously moves upwards and is discharged through the air outlet pipe 2, the smoke is firstly filtered through the meshes 41, oil drops formed on the drainage screen plate 4 flow downwards along the flow guide holes communicated in the meshes 41, and finally the smoke flows back to the equipment through the air outlet pipe 2.
