The multifunctional rotational flow oil strainer

Technical field

The utility model belongs to oily filter, particularly a kind of multifunctional rotational flow oil strainer.

Background technology

In order to make full use of resource and to cut operating costs, industrial circle contains water and mechanical admixture, wherein contained moisture content with oil more; In commercial Application, only use the precipitation method to separate; Effect is relatively poor, so oil product in use inevitably contains moisture content, causes oily calorific value to descend; Combustion stability reduces, and phenomenons such as oil gun fire extinguishing often occur; Impurity contained in the oil can cause impurity to stop up the phenomenon of filter screen when using ordinary filtration, so need frequent cleaning filter screen, maintenance workload is bigger, and the stability of influence operation.In industrial processes, often owing to consider net congestion affects normal productive process.

The utility model content

The purpose of the utility model is to contain moisture content to the oil of mentioning in the background technology, causes oily calorific value to descend, and combustion stability reduces, and phenomenons such as oil gun fire extinguishing often occur; Impurity contained in the oil is when using ordinary filtration; Can cause impurity to stop up the phenomenon of filter screen; So need frequent cleaning filter screen, maintenance workload is bigger, and the deficiency of the stability of influence operation and a kind of multifunctional rotational flow oil strainer is provided; It is characterized in that oil-in 1 is weldingly connected with cylindrical shell 2; Cone 3 is welded on the bottom of cylindrical shell 2; Oil return pipe 9 utilizes the coaxial installation of flange with absolute oil sleeve pipe 10 with cylindrical shell 2, and oil return pipe 9 is extend into the centre position of cone 3 downwards; Filter screen 6 is installed in oil return pipe 9; Oleophilic drainage film 7 is installed in outer side compression at filter screen 6; End oil export pipe 4 is welded on the lower port of cone 3; The coaxial installation draining in oil export pipe 4 outsides sleeve pipe 11 end of at; Hydrophilic oleophobic filter membrane 13 is installed on the inwall of end oil export pipe 4.

Bottom cone 14 ports of said absolute oil sleeve pipe 10 flush with oil return pipe 9 lower port.

Said cylindrical shell adopts the Archimedes spiral pattern.

The cone angle of said cone is 60 degree～80 degree.

Said oleophilic drainage filter membrane is pricked the fiber-ball filter media that knot forms by the modified fibre silk; Be the stainless steel fibre mesh grid promptly by base material; The modified fibre silk is the fine and close silica micro nano-coatings of one deck in the stainless steel fibre surface coverage, adopts the technology of dipping or spraying that colloidal sol is coated on the wire netting.

The cone angle of the bottom cone of said absolute oil sleeve pipe is 60 degree～80 degree.

The useful effect of the utility model is: compare with background technology, have:

1. cylindrical shell has adopted the Archimedes spiral pattern, can reduce drag losses about 20% than the column type separator;

2. the oily flow velocity in the oil return pipe is higher, can get wall upper filter screen surface express developed, keeps this cleaning surfaces to the greatest extent, can make reach 5000 hours the service time of filter screen;

3. the oleophilic drainage filter membrane of installing in the outside of filter screen has good lipophile and hydrophobicity, can prevent that the moisture content in the oil from getting into the absolute oil sleeve pipe, thereby has guaranteed originally not to be with moisture content from the oil base that the absolute oil outlet is flowed out;

4. the hydrophilic oleophobic filter membrane in the installed inside of underflow pipe has good hydrophily and oleophobic property, can in time discharge the moisture content of separating through rotation;

5. the contained impurity of oil separates with the centrifugal force that moisture content mainly relies on rotation to produce; Discharge from underflow opening then; So just make that the impurity and the moisture content that enter into oil return pipe filter screen place are reducing the service time of the filter quality of assurance and filter screen, filter membrane and life-span greatly.

The specific embodiment

The utility model provides a kind of multifunctional rotational flow oil strainer.Explain below in conjunction with accompanying drawing.In Fig. 1, multifunctional rotational flow oil strainer structural principle sketch map shown in Figure 2, cylindrical shell 2 adopts Archimedes spiral patterns (as shown in Figure 2).Oil-in 1 is weldingly connected with cylindrical shell 2; Cone 3 (cone angle is 60 degree～80 degree) is welded on the bottom of cylindrical shell 2; Oil return pipe 9 utilizes the coaxial installation of flange with absolute oil sleeve pipe 10 with cylindrical shell 2, and oil return pipe 9 is extend into the centre position of cone 3 downwards, and the bottom cone 14 of absolute oil sleeve pipe 10 (cone angle of cone is that 60 degree～80 are spent) port flushes with oil return pipe 9 lower port.Filter screen 6 is installed in oil return pipe 9; Oleophilic drainage film 7 is installed in outer side compression at filter screen 6; End oil export pipe 4 is welded on the lower port of cone 3; The coaxial installation draining in oil export pipe 4 outsides sleeve pipe 11 end of at; Hydrophilic oleophobic filter membrane 13 is installed on the inwall of end oil export pipe 4, and this hydrophilic oleophobic filter membrane 13 is to prick the fiber-ball filter media that knot forms by the modified fibre silk.
