Description

Technical Field

[0001] The utility model relates to the technical field of oil mist separation equipment, in particular to a superimposed wire mesh oil mist separation collector. Background Art

[0002] The existing cylinder-shaped oil mist separators mostly use the air inlet of the air inlet pipe located in the center of the cylindrical filter screen, and then the oil mist enters, flows out from the surrounding of the filter screen, completes the oil mist separation, and is finally sucked away by the exhaust equipment. However, the structure has certain disadvantages. For example, in order to expand the oil mist separation effect, it is necessary to make the space in the cylinder larger, increase the contact area between the oil mist and the filter screen, so that the oil mist can be separated quickly, and the large space in the cylinder is also easy to maintain and clean later, but the result is that the volume of the entire equipment is larger, and the space in the cylinder is made smaller to just accommodate the air outlet of the air inlet pipe, but this structure reduces the surface area in contact with the oil mist, and thus the oil mist separation effect is slightly worse, so according to the above situation, an improved technology is proposed. Utility Model Content

[0003] The utility model aims to provide a stacked wire mesh oil mist separation collector which is small in size and occupies little space while not reducing the oil mist separation effect, so as to solve the problems raised in the above background technology.

[0011] 1. The utility model installs the oil mist separation central pipe, i.e., the air outlet pipe, in the oil mist separation built-in wire mesh component. The oil mist gas enters the separation tank through the air inlet pipe, then enters the interior around the oil mist separation built-in wire mesh component, and then enters the oil mist separation central pipe through the air vents. The gas is then extracted by the vacuum equipment, leaving grease and some impurities. Compared with the existing products, the space utilization of the utility model product is compact and reasonable, and the oil mist separation effect is also better.

[0012] 2. The built-in wire mesh assembly for oil mist separation is composed of several superimposed filter screens, which are easy to disassemble and clean. In order to avoid gaps between the overlapping filter screens, a spring is provided to compensate for the gaps through elastic force, so that the gaps are tightly connected to prevent oil mist from passing through the gaps, and the structural design is more reasonable.
