The utility model is described in further detail below with reference to the figures and specific examples.

As shown in fig. 1-4, a conical dust and oil removing filter comprises:

the upper cover moulds shell 10, the upper cover moulds shell 10 and is discoid, and it turns over outward along 12 downwards outward, the lower extreme surface middle part integrated into one piece that the upper cover moulded shell 10 sets up fixing base 11, and fixing base 11 is the circular inserting connection slot of the coaxial setting of mould shell 10 in the upper cover, the periphery array of fixing base 11 sets up a plurality of mounting grooves 111, and mounting groove 111 is used for pegging graft fixed strip 31, slotted hole shape and size and fixed strip 31 adaptation.

The lower cover plastic casing 20 is arranged below the upper cover plastic casing 10 in parallel and coaxially, the lower cover plastic casing 20 is annular, an annular groove 21 is formed in the lower cover plastic casing 20, the inner diameter of the lower cover plastic casing 20 is larger than the diameter of the upper cover plastic casing 10, and the upper cover plastic casing 10 and the lower cover plastic casing 20 correspondingly form a conical body.

The conical filter element 30 arranged between the upper cover plastic shell 10 and the lower cover plastic shell 20 comprises a plurality of fixing strips 31, wherein the annular arrays are arranged between the upper cover plastic shell 10 and the lower cover plastic shell 20, the lower ends of the fixing strips 31 are arranged in the annular groove 21, and the upper ends of the fixing strips 31 are inserted into the installation grooves 111. And the filter screen 32 is sleeved on the outer side surfaces of the fixing strips 31. The non-woven fabric 33 is sleeved on the outer side surface of the filter screen 32, and the non-woven fabric 33 is folded to form a plurality of folds arranged at intervals.

When the filter is used, the filter is inverted to be installed, dust particles and oil are firstly attached to the filter element when passing through the filter, oil drops are naturally polymerized and then settled at the bottom of the filter layer under the action of gravity, oil can be better removed, and meanwhile, the filter is simple in structure, convenient to disassemble and assemble, and convenient to clean deposited oil stains at the bottom of the filter layer and replace the filter element.

And, the outer layer of toper filter core 30 selects to adopt non-woven fabrics 33, and it has stronger gas permeability, light, can recycle simultaneously, and it is good to use filtering quality on the filter, and very big reduction cost, also environmental protection more.

As a further improvement, the non-woven fabric 33 has 155-160 folds. The folds are arranged at intervals, so that the contact area of the filter is increased, and the filtering efficiency is improved.

As a further improvement, the width of the non-woven fabric 33 is 207-208 mm, and the folding height of the non-woven fabric 33 is 30-33 mm. The width size is set in this interval and makes the size of each fold more suitable, and the size of rolling over the height simultaneously sets up in this interval, and the compact structure of whole filter is small and exquisite portable, more conveniently assembles in the equipment that needs remove dust and deoiling.
