Description

A kind of disc stack filter core

Technical field

The utility model belongs to separation technology field, and in particular to it is a kind of in wind-powered electricity generation gearbox lubrication oil filtration it is folded Disk filter core.

Background technology

Analysis according to statistics, the failure 80% that wind-powered electricity generation gearbox generates come from the pollution of oil product, major pollutants There are metal, dust, the grains of sand and rubber etc., while oil degradation also will produce the impurity such as resin, oxide residual and water.This A little pollutant shadows seriously ring safety and the service life of wind-powered electricity generation gearbox.A large amount of repairs and replacement oil product substantially reduce work Efficiency, while greatly increasing use cost.

Existing solution is to install oil filter on wind-powered electricity generation gearbox, is filtered to lubricating oil by oil filter, To remove the pollutant in lubricating oil, to extend the service life of lubricating oil.As the core component of oil filter, filter core it is good The bad service life for directly determining lubricating oil.Existing overwhelming majority filter core but can not for the solid particle in filtering lubricant oil The resin and water generated in removal oil product degradation process, therefore prior art problem can't be solved；Part filter core can remove Moisture in oil product, but circulating resistance is big, and pollutant carrying capacity is poor, and service life is short；In addition, filter core preparation process in the prior art Complexity, such as application No. is CN201620217204.5 Chinese patents to disclose a kind of combined filter element for oil product filtering, Complicated, production cost is higher, is unsuitable for industrialization and uses.

Utility model content

Technical problem to be solved by the utility model is to provide a kind of disc stack filter core, can solve to filter in the prior art Core cannot be removed effectively the technical issues of water and resin in oil product, and its is simple in structure, is suitable for industrialization and uses.

In order to solve the above technical problems, the technical solution adopted in the utility model：A kind of disc stack filter core, it is characterised in that： Including several filter plates, the filter plate is suppressed using wood-fibred paper pulp and is obtained, and is hollow structure inside filter plate, and several filter plates are same The folded connection of uranium pile forms column structure.

Further, the surface of the filter plate is provided with several crisscross grooves.

Further, the width of the crisscross grooves is 3~10mm.It should be noted that the width of crisscross grooves is Spacing between the two neighboring protrusion of up and down or left and right separated by crisscross grooves on filter plate.

Further, the thickness of the filter plate is 5~20mm.

Further, the hollow structure is round filter opening.

Further, the aperture of the round filter opening is 10~30mm.

Further, pass through bonding connection between several filter plates.

The beneficial effects of the utility model：

1) the utility model using the stronger wood-fibred of water imbibition as filter plate raw material, by disc stack filtered by the lubricating oil after pollution The outer surface of core enters to inside filter core, and the moisture in oil product is absorbed by wood-fibred, and solid particle is intercepted to outside filter core Surface, clean oil on disc stack filter core at the hollow structure of each filter plate by being collected among filter core, finally by oil filter Clean oil is expelled back into gear-box, filtering accuracy is high, and pollutant carrying capacity and oil and water separation capability are strong, and circulating resistance is small；

2) multiple filter plates, which are arranged, can increase filter area, and crisscross grooves are arranged in the surface of every filter plate, further increase Add the filter area of disc stack filter core, improves pollutant holding capability, further increase the service life of disc stack filter core；

3) fluid sealant hydropexis is used, both can guarantee and be connected firmly between filter plate, and disc stack filter core is through long-term oil product point From rear, without departing from extending the service life of disc stack filter core, and manufacturing process is simple, manufacturing cost is low between filter plate.

Specific implementation mode

The technical scheme in the utility model embodiment is clearly and completely described below, it is clear that described reality It is only the utility model a part of the embodiment to apply example, instead of all the embodiments.Based on the embodiments of the present invention, Every other embodiment obtained by those of ordinary skill in the art without making creative efforts, belongs to this reality With novel protected range.

Embodiment 1：

A kind of disc stack filter core, as shown in Figures 1 to 3, including several filter plates 1, wherein filter plate 1 suppressed using wood-fibred paper pulp and , the thickness of individual filter plate 1 is 10mm, and the height of disc stack filter core is depending on specific scale.It should be noted that if to carry High filtering precision can increase the quantity of filter plate 1.Filter plate number is more, and the filter area of disc stack filter core is bigger, and the precision of filtering is got over When height, i.e. disc stack filter core height are identical, the thickness of individual filter plate 1 can be reduced, to increase filter plate number.In the present embodiment, fold The height of disk filter core is 200mm.Several filter plates 1 coaxially stack and are adhesively fixed to form column structure by epoxide-resin glue.Filter It is hollow structure inside plate 1, in the present embodiment, hollow structure is specially round filter opening 2, and the aperture of round filter opening 2 is set as 20mm.The surface of filter plate 1 is provided with several crisscross grooves 3, and the width of crisscross grooves 3 is 5mm.Crisscross grooves 3 are arranged can be with Increase filter area, improve the pollutant carrying capacity of disc stack filter core, and can guarantee that solid particle is stuck in crisscross grooves 3, will not enter Inside disc stack filter core, the high-purity separation of oil product is realized.The oil product filtered is after the outer layer of disc stack filter core passes through disc stack filter core Impurity is filtered, the water in oil product is absorbed by filter plate, and filtered oil product is fixedly separated, and solid particle is adsorbed on filter plate In crisscross grooves, clean oil is pooled to through crisscross grooves at the round filter opening of filter plate, and disc stack filter core may be mounted at oil filter Or in dedicated container, the clean oil product in round filter opening is returned in gear-box by pumping.It is folded described in the present embodiment Filter area and higher pollutant holding capability of the disk filter core compared with the common filter core under same volume with bigger, the processing of oil product Ability is 1.5 times of common filter core or more, and service life can reach 12 months or more, is reduced caused by frequently replacing filter core Cost allowance.

Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with the power Subject to the protection domain that profit requires.
