Description

A kind of plate frame oil filter

Technical field

The utility model relates to a kind of plate frame oil filter.

Background technology

The structure of plate frame oil filter is generally by filter bed, and the element such as oil pump and coarse filter forms. Wherein, filter bed comprises a filtrate housing and is juxtaposed on many groups filtering bodies of filter housing body cavity indoor, filtering bodies comprises screen plate, the filter frame of coupling, the filter paper as filtration medium or filter cloth it is lined with between filter plate and filter frame, rely on the pressure of hold-down gear filter plate and filter frame to be fixed again and form an independent filtration chamber, the filter paper being pressed between filter plate and filter frame or filter cloth filtration. But existing plate filter, filtering bodies is generally and is directly installed on bottom housing cavity. Owing to often being difficult to realize perfectly sealing between the filter plate of filtering bodies and filter frame, therefore the fluid between filter plate and filter frame can be exuded to bottom housing cavity under pressure, like this, filtering bodies bottom is dipped in the fluid bottom housing cavity, result in formation of the easy access of fluid, namely the fluid that the filtering bodies of ingress is oozed out directly enters into from external channel in the filtering bodies in exit, have impact on filter quality greatly, reduces filter effect. , position by filtering chamber's inner chamber side when existing filtering bodies is installed meanwhile, there is the defect installing inconvenience.

In addition, screen plate is the core component of plate filter, screen plate and filter frame and forms filtering bodies together with being sandwiched in filter cloth between the two, and many group filtering bodies are arranged in filtrate housing to form filtration fraction structure side by side. But the structure of existing screen plate also exists poor sealing, usually cause fluid to leak out filter space from combination section, rib limit, inconvenience is installed, the shortcoming that filter effect is poor.
