Description

The backwash oil strainer

Technical field

The utility model relates to machinery industry lube oil purification specialty, especially refers to a kind of backwash oil strainer.

Background technology

In daily activity in production, all mechanical movements all be unable to do without lubricating oil, and the quality of oily condition is determining operational efficiency and the service life of plant equipment.A deteriorated leading indicator of oil quality is granule foreign and the oxide impurity in oil product, even equipment is caused damage along with the increase of content can reduce the oil product result of use greatly.The impurity that removes in oil product is the important content that lubricating oil is safeguarded.Existing oil filtering device often stops up in the absolute oil process, if use disposable filter core can cause production cost to increase, can only be also to shut down to change and clean even use filter core capable of washing, thereby reduce operating efficiency.It is 02284329.9 utility model patent that is called " backwash filter " that a patent No. is arranged, and has announced a kind of backwash filter, is suitable for the industry sewage disposals such as oil, chemical industry and light industry.Its structure is: the sewage inlet pipe (9) that comprises cylindrical shell (8) and be attached thereto, trash discharge mouth (6), filtering core (5), filtrate discharge pipe (3), and control valve; Also comprise back purge system, the autocontrol valve (2) that this device is provided with a backwash pipeline (13) and is attached thereto, backwash pipeline (13) one ends are communicated with filtrate discharge pipe (3), the other end is provided with nozzle (11), and nozzle is positioned at the top of filtering core (5) cavity.This utility model has long service life, is widely used and do not shut down advantages such as automatically carrying out backwash, is the comparatively ideal automatic cleaning machine of current oil, chemical industry and light industry.This utility model has solved the backwash problem that trade effluent is processed, improved operating efficiency, but and be not suitable for oil product and filter, this is because in water, impurity can not discharge and can cause secondary pollution to environment, well cuts can not directly discharge, the unified processing after must reclaiming.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of simple in structure, high efficiency, free of contamination backwash oil strainer are provided for above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the scheme that adopts: be formed by connecting by pipeline and valve with coarse filter, back flushing device, oil pump, fine filter, but the oil pump rotating is used, utilize valve to change oil product and flow to, thus the backwash of the lubricated oil filtration of realization and system.

As improvement, described coarse filter is a dismountable sealed shell of tank, have the first oil-in, the first oil-out and backwash mouth, inside is provided with coarse filter element, the first oil-in place is provided with valve and is connected with fuel tank by pipeline, the first oil-out is connected with the oil pump pipe, and the backwash mouth is connected with back flushing device with pipeline by valve.

Improve again, described fine filter is dismountable sealed shell of tank, inside is provided with smart filter core, have the second oil-in and the second oil-out on tank body, wherein the second oil-out position is higher than the second oil-in, the second oil-in is connected with oil pump by pipeline, and the other end is connected with smart filter core, and the second oil-out is connected with fuel tank by pipeline.

Improve again, described back flushing device is dismountable sealed shell of tank, inside is provided with the netted dirty device of receiving, have the 3rd oil-in and the 3rd oil-out on tank body, the 3rd oil-in is connected with the backwash mouth of coarse filter by valve, pipeline, the 3rd oil-out is connected with fuel tank by pipeline, and the dirty device of receiving is arranged on the 3rd into and out of between hydraulic fluid port and can clean and reuse.

As further improvement, coarse filter, back flushing device, oil pump, fine filter arrange one or more sets.

Compared with prior art, the utility model has realized that by install valve and back flushing device additional on the typical filter device online backwashing of coarse strainer and the dirt recovery of filtering focus on and do not shut down, and improved operating efficiency, have reduced cost.

Description of drawings

Fig. 1 is the structure principle chart of the utility model embodiment;

The specific embodiment

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, the backwash oil strainer of the present embodiment is formed by connecting by pipeline by coarse filter 1, back flushing device 2, oil pump 3, fine filter 4.Coarse filter 1 is a dismountable sealed shell of tank, have the first oil-in 11, the first oil-out 12 and backwash mouth 13, inside is provided with coarse filter element 7, the first oil-in 11 places are provided with valve 6 and are connected with fuel tank 20 by pipeline 5, the first oil-out 12 is connected by pipe with oil pump 3, and backwash mouth 13 is connected with valve by pipeline and is connected with back flushing device 2.Fine filter 4 is dismountable sealed shell of tank, inside is provided with smart filter core 8, have the second oil-in 14 and the second oil-out 15 on tank body, wherein the second oil-out 15 positions are higher than the second oil-in 14, the second oil-in 14 is connected with oil pump 3 by pipeline, the other end is connected with smart filter core 8, and the second oil-out 15 is connected with fuel tank 20 by pipeline.Back flushing device 2 is dismountable sealed shell of tank, inside is provided with the netted dirty device 10 of receiving, have the 3rd oil-in 16 and the 3rd oil-out 17 on tank body, oil-in 16 is connected with valve by pipeline and is connected with the backwash mouth 13 of coarse filter, the 3rd oil-out 17 is connected with fuel tank 20 by pipeline, and the dirty device 10 of receiving is arranged between the 3rd oil-in 16 and the 3rd oil-out 17.
