Abstract

Disclosed is a two-stage back flush self-cleaning filter, which comprises a one-stage filter, and is characterized in that: a two-stage filter is connected at a drain outlet of the one-stage filter. The two-stage filter is a well-known hand filter. The utility model can realize functions of two-stage filtration and back flush by shaking a handle, so as to achieve secondary filtration of lubricating oil and back flush simply and effectively, save costs, improve the working efficiency, make the filtration cleaner and more complete, greatly reduce the breakage to an engine by the lubricating oil with impurities, reuse and recycle more lubricating oil, and greatly reduce the discharge of the lubricating oil with impurities, and the utility model can produce huge economic effects, and can better protect the environment.

Description

Secondary backwashing self-cleaning formula filter

Technical field

The utility model relates to a kind of secondary backwashing self-cleaning formula filter, belongs to the cleaner field.

Background technology

At present, well-known general cleaning filter is direct the discharge or polyphone papery or net formula filter core filter of a large amount of filtrates of backwash being come out to carry impurity, impure filtrate is rushed out in backwash, performance and structural limitations because of filter self, artificial disassembling, assembling and replacing or clean the sump oil filter core, the function that does not have backwash once more, like this because once filtration can produce a large amount of filtrate of containing impurity, these filtrates papery filter core device of directly discharging or contact, not only caused a large amount of wasting of resources contaminated environment, and frequently manually dismounting, clean, change a plurality of papery element kits, wasted great amount of manpower, reduced operating efficiency, special steamer as the work of going to sea, need filter a large amount of lubricating oil every day, if be that independent one-level is filtered, produce a large amount of filtrate of containing impurity, need to consume a large amount of papery filter core devices, cost will increase greatly, and these filtrations lubricating oil once will be if directly discharge will cause the environmental pollution that there is no need and huge waste.

The utility model content

According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can save cost, increase work efficiency, avoid unnecessary environmental pollution and can carry out the secondary backwashing self-cleaning formula filter of secondary filter and backwashing function.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of secondary backwashing self-cleaning formula filter, comprise one-level filtration filter, and it is characterized in that: filter filter sewage draining exit place in one-level and connect the cascade filtration filter.

Described cascade filtration filter is that known hand-rail type filters filter.

Operation principle and process:

The lubricating oil that needs to filter at first enters one-level filtration filter, finish and filter and backwash (prior art), filtering the oil-out of clean lubricating oil by grade one filter enters Oil Tank and circulates again, and the lubricating oil that has impurity after the backwash will enter hand-rail type by the sewage draining exit that one-level is filtered filter and filter filter, by regulating back pressure and shaking manually that handle filters and backwash (prior art), filter operation through twice like this, most lubricating oil are circulated again continue to utilize, produce less bits, cleaning regularly gets final product.

The beneficial effect that the utility model had is: save cost, increase work efficiency, avoid unnecessary environmental pollution and can carry out secondary filter and backwash, make more lubricating oil recycling again, produce huge economic effect.

Description of drawings

Fig. 1 the utility model structural representation

Wherein: 1, one-level is filtered filter; 2, sewage draining exit; 3, hand-rail type filters filter; 4, handle.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described further: a kind of secondary backwashing self-cleaning formula filter, comprise one-level filtration filter 1, sewage draining exit 2 places of filtering filter 1 in one-level connect hand-rail type filtration filter 3.The lubricating oil that needs to filter at first enters one-level filtration filter 1, finish filter and backwash after (prior art), filtering the oil-out that clean lubricating oil filters filter 1 by one-level circulates again, and the lubricating oil that has impurity after the backwash will enter hand-rail type by the sewage draining exit 2 that one-level is filtered filter 1 and filter filter 3, handle 4 filters and backwash (prior art) by manually shaking, the handle of solid line shown in the figure 4 expression hand-rail types filter the backwash state of filter 3, dotted line handle 4 expression hand-rail types filter the filtration state of filter 3, again the lubricating oil of Guo Lving continues recycling by the oil-out that hand-rail type filters filter 3, filter operation through twice like this, most lubricating oil are circulated again, produce less bits, cleaning regularly gets final product.

Claims

1. a secondary backwashing self-cleaning formula filter comprises one-level filtration filter (1), and it is characterized in that: the sewage draining exit (2) that filters filter (1) in one-level locates to connect the cascade filtration filter.

2. secondary backwashing self-cleaning formula filter according to claim 1 is characterized in that: described cascade filtration filter is that known hand-rail type filters filter (3).
