Description
Technical field
The utility model relates to a kind of filter plant, and more specifically, it relates to a kind of membrane filter.
Background technology
Air filter (AirFilter) refers to air filter, is generally used between car for cleaning, clean room, clean operating room, laboratory and clean room, or dust-proof for electric mechanical signal equipment etc. general air filter at least comprises an inlet mouth and an air outlet, filter paper it is provided with between inlet mouth and air outlet, for elimination impurity and moisture, but there is following problem in the air filter in currently available technology, change filter paper difficulty bigger, in order to solve the problem, the Chinese patent that application number is CN201410009373.5 describes a kind of assembling and changes filter core conveniently, a kind of air filter that cost is low, but although this kind of strainer is provided with two layers of filtration, but general filter paper filtering effect is better, need the number of times changed also more, if so directly changing filter core by which, possible effect is poor, and also to be removed tracheae due to during dismounting simultaneously, so it is equally comparatively loaded down with trivial details.
Practical novel content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of filter paper to change membrane filter easily.
For achieving the above object, the utility model provides following technical scheme: a kind of membrane filter, comprise inlet pipe and escape pipe, described inlet pipe and escape pipe are fixed on a pedestal, described pedestal is provided with groove, being connected with cover plate on described groove, described escape pipe runs through pedestal setting and forms a through hole in described groove; Described pedestal is also provided with the first annular gas tank, described first annular gas tank is connected with described inlet pipe and is provided with the first venting hole, described cover plate is provided with filter paper, described filter paper and cover plate form a pre-filter chamber, described pre-filter chamber is connected described first annular gas tank, and described pre-filter chamber and described escape pipe are isolated with filtering gas by filter paper; Described pedestal is also removably connected with sealing cover, extrudes the sealing to realize between the first annular gas tank and pre-filter chamber in described cover plate to described groove when described sealing cover and pedestal are fixing.
By such setting, first, pedestal is provided with two pipelines, a pipeline is used for air inlet, a pipeline is used for giving vent to anger, escape pipe directly runs through pedestal, and inlet pipe is connected with the first annular gas tank gas groove, gas is sent into from inlet pipe, via the first annular gas tank, gas is sent in pre-filter chamber owing to there being air pressure (due to filter paper) in pre-filter chamber, gas can be made to filter from the pore of filter paper, play good filter effect, same filter paper is directly arranged on pedestal by a cover plate, then undertaken being arranged on pedestal by cover plate by sealing cover, when needing to replace filter paper, directly then cover plate is replaced by dismounting sealing cover, owing to cover plate and pedestal there is no direct fixed relationship, so it is easy to operate.
Further: described cover plate also comprises second ring gas groove, described second ring gas groove being provided with the second row pore being connected with pre-filter chamber, described second ring gas groove coordinates with the first annular gas tank and formed air cavity. By the setting of the first annular gas tank and second ring gas groove, ensure that stopping property, and gaseous interchange effect is more, the air pressure that whole equipment is subject to balances more.
Further: described first annular gas tank and second ring gas groove are made by elastomeric material. Made by elastomeric material, improve stopping property further.
Further: the cross section of described first annular gas tank and second ring gas groove is arch and the opposing setting of its projected direction. Arrange like this, under ensureing the prerequisite of stopping property so that the mistake air cavity of formation is more stable.
Further: be also provided with annular stupefied bar on described groove, described filter paper and the stupefied bar of described annular are conflicted. If not having annular stupefied bar, so filter paper may by air pressure top to the through hole in inlet pipe, and the gas of pre-filter chamber also can only carry out filtrate on the face of this pore size.
By adopting technique scheme, compared to existing technology, serve following effect, by such setting, first, pedestal is provided with two pipelines, a pipeline is used for air inlet, a pipeline is used for giving vent to anger, escape pipe directly runs through pedestal, and inlet pipe is connected with the first annular gas tank gas groove, gas is sent into from inlet pipe, via the first annular gas tank, gas is sent in pre-filter chamber owing to there being air pressure (due to filter paper) in pre-filter chamber, gas can be made to filter from the pore of filter paper, play good filter effect, same filter paper is directly arranged on pedestal by a cover plate, then undertaken being arranged on pedestal by cover plate by sealing cover, when needing to replace filter paper, directly then cover plate is replaced by dismounting sealing cover, owing to cover plate and pedestal there is no direct fixed relationship, so it is easy to operate.
