Abstract
The utility model discloses a pressure filter, which comprises a cylinder body provided with a discharge hole, a lid provided with a feeding hole and a filter element provided with a flanging. The cylinder body and an upper flange at the lower part of the lid form a detachable connection through a lower flange at an opening end of the cylinder body; a step surface is formed inside the lower flange; the flanging of the filter element is supported on the step surface; a sealing device is arranged between the lower flange of the cylinder body and the upper flange at the lower part of the lid. The sealing device has the structure that an annular groove is formed on the upper flange and/or the lower flange; an obturating ring is arranged in the annular groove; preferably, the obturating ring is an O-type rubber obturating ring. The pressure filter has good sealability and is not easy to leak; because an annular ring is arranged on the step surface inside the lower flange, the clamping of a filtration fabric bag is facilitated. The pressure filter has good leak tightness, and is widely used in the industries such as medicine, chemical engineering, foods, beverages, etc.
Description
Technical field
The utility model relates to a kind of industries such as medicine, chemical industry, food, beverage that are used for, by applying the pressure filter that certain pressure makes solid-liquid, sticky class material Separation of Solid and Liquid.
Background technology
Present widely used pressure filter comprises the cylindrical shell with discharging opening, the filter core that has the cover of charging aperture and have flanging; On cover top handwheel and rocking arm can be housed, described cylindrical shell is connected with the upper flange bolt of described cover bottom by the lower flange at its opening end place, and described lower flange inboard is provided with step surface, and the flanging of filter core is bearing on this step surface.When carrying out the press filtration operation, the filter cloth bag upper edge limit that solid-liquid or sticky class material are housed is outwards turned down, and be clamped between the upper and lower flange by bolt, after exerting pressure, liquid leaches.There is the shortcoming of two aspects in such pressure filter: on the one hand, owing to be positioned at, filter cloth bag between the lower flange has fold, especially working as the filter cloth bag is multilayer, for example by canvas bag, woolsack, during multiple bag suit such as filter bag lamination, fold will be more, thicker, though on, bolt between the lower flange is twisted very tightly, but reason owing to the bag fold, on making, still have a lot of slits between the lower flange, in pressure-filtering process, the liquid that filters out is from last, run in slit between the lower flange, emit, drip, leakage phenomenons such as leakage often take place, and when material had harm to environment, the liquid of leakage also can cause the pollution of environment; On the other hand, with the filter cloth bag is suitable for reading when being placed on the lower flange, slippage often takes place, inconvenient clamping.
The utility model content
The technical problems to be solved in the utility model provides a kind of have good seal performance, antileakaging pressure filter.
For solving the problems of the technologies described above, a kind of pressure filter of the present utility model, comprise the cylindrical shell with discharging opening, the filter core that has the cover of charging aperture and have flanging, described cylindrical shell removably connects by the lower flange at its opening end place and the upper flange formation of described cover bottom, described lower flange inboard is provided with step surface, the flanging of described filter core is bearing on this step surface, and its improvement is: also be provided with sealing device between the upper flange of the lower flange of described cylindrical shell and described cover bottom.
Described sealing device can be made of one lower flange annular groove that is located at described lower flange upper surface and the lower flange sealing ring that is positioned at this lower flange annular groove at least.
Described sealing device also can be made of one upper flange annular groove that is located at described upper flange lower surface and the upper flange sealing ring that is positioned at this upper flange annular groove at least.
Described sealing device can also be by at least one lower flange annular groove that is located at described lower flange upper surface, be positioned at the lower flange sealing ring of this lower flange annular groove and constitute described upper flange annular groove and the interlaced setting of described lower flange annular groove by at least one upper flange annular groove that is located at described upper flange lower surface, the upper flange sealing ring that is positioned at this upper flange annular groove.
As a kind of improvement of the present utility model, the step surface of described lower flange inboard is provided with an annular ring.
After adopting such structure, owing between the upper flange of the lower flange of cylindrical shell and cover bottom, be provided with sealing device, the sealing device is preferably on upper flange and/or lower flange annular groove is set, and sealing ring is set in annular groove, and the sealing circle is preferably O type rubber seal.When the bolt between the upper and lower flange is tightened, be positioned at the sealing ring compressive deformation of annular groove, get in the slit that filter cloth bag fold causes effective like this generation that stops the leakage of filtrate phenomenon.Again owing to be placed with an annular ring on the step surface of lower flange inboard, this annular ring can be with on the filter cloth bag step surface that is clamped in the lower flange inboard suitable for reading, and the filter cloth bag is suitable for reading like this when being placed on the lower flange, is difficult for slippage, and is easy to setup.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of a kind of pressure filter of the present utility model.
Fig. 2 is the amplification view at A place among Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of pressure filter, comprise cylindrical shell 1 with discharging opening 1-1, the filter core 3 that has the cover 2 of charging aperture 2-1 and have flanging 3-1, described cylindrical shell 1 removably connects by the lower flange 1-2 at its opening end place and the upper flange 2-2 formation of described cover 2 bottoms, the described known conventional means such as to adopt bolt connection or anchor ear that removably connects, described lower flange 1-2 inboard is provided with step surface 1-2-3, the flanging 3-1 of filter core 3 is bearing on this step surface 1-2-3, also is provided with sealing device between the upper flange 2-2 of the lower flange 1-2 of described cylindrical shell 1 and described cover 2 bottoms.
