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. 1-2, a ventilation cap comprises a mounting base 1 and an exhaust pipe 4, a condensing pipe 3 is sleeved at the joint of the mounting base 1 and the exhaust pipe 4, the condensing pipe 3 is communicated with the mounting base 1 and the exhaust pipe 4, a filter screen component 2 positioned between the mounting base 1 and the exhaust pipe 4 is sleeved in an inner cavity of the mounting base 1, the filter screen component 2 is concave and detachably mounted, the end of the filter screen component 2 is connected to the condensing pipe 3, oil smoke generated during operation of equipment moves upwards through an inlet of the mounting base 1, the oil smoke is filtered by the filter screen component 2 and then is discharged through the condensing pipe 3, in the filtering process of the filter screen component 2, the filter screen component 2 cools and condenses the oil soot under the condensation transmission effect of the condensing pipe 3, the condensed oil soot moves downwards under the action of gravity and then flows back to the equipment through a flow guide hole on the filter screen component 2, so as to effectively reduce the oil content in the oil smoke, can pull down the washing with filter screen subassembly 2 when necessary, lossless spare, filter screen subassembly 2 comprises last filter screen 21 and lower filter screen 22, go up filter screen 21 and filter screen 22 from top to bottom inlay the cover mutually and install the inner chamber at mount pad 1, and be equipped with the reservation clearance between the opposite face of going up filter screen 21 and lower filter screen 22, filter the oil smoke at filter screen subassembly 2, the in-process of cooling and condensation, go up filter screen 21 and lower filter screen 22 and carry out above-mentioned processing procedure to the flue gas in proper order, when guaranteeing the flue gas treatment sufficiency, the oil content in the oil smoke has further been reduced.

The upper filter screen 21 and the lower filter screen 22 are not in contact with the inner cavity wall of the mounting base 1, the bottom ends of the upper filter screen 21 and the lower filter screen 22 are in a slope shape, the diversion holes in the upper filter screen 21 and the lower filter screen 22 are distributed in a staggered mode, the diameter value of the through hole in the bottom end of the upper filter screen 21 is smaller than that of the through hole in the bottom end of the lower filter screen 22, when oil smoke is filtered and condensed through the filter screen assembly 2 and the condensation pipe 3, the upper filter screen 21 and the lower filter screen 22 sequentially treat the smoke to ensure the sufficiency of smoke treatment, and meanwhile oil produced by smoke treatment flows along the slope in the bottom ends of the upper filter screen 21 and the lower filter screen 22 under the action of gravity.

The projection of the bottom end of the lower filter screen 22 on the mounting base 1 surrounds the whole oil smoke inlet, so that the effectiveness of reducing the oil content in the smoke is further ensured while the smoke generated by the equipment completely enters the filter screen assembly 2 and the condenser pipe 3 for filtering and condensing.

The working principle is as follows:

firstly, a ventilation cap composed of components such as a mounting seat 1 and an exhaust pipe 4 is fixed on equipment through bolts, when the equipment runs, the temperature of lubricating oil rises to generate oil smoke, the oil smoke passes through the mounting seat 1, passes through a filter screen component 2 composed of an upper filter screen 21 and a lower filter screen 22 and a condenser pipe 3 and then is exhausted into the atmosphere through the exhaust pipe 4, the oil smoke passes through meshes of the upper filter screen 21 and the lower filter screen 22 and a pipe wall of the condenser pipe 3 every time and has a certain cooling and condensing effect, and oil mist in the oil smoke is condensed into oil drops and flows back into the equipment along the slope-shaped bottom ends of the upper filter screen 21 and the lower filter screen 22.

In the description of the present invention, it is to be understood that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly and include, for example, fixed connections, detachable connections, or integral parts; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
