Abstract
The utility model discloses a filter device, which comprises an upper cavity, a lower cavity, filter cloth and a perforated plate. The filter cloth is arranged on the perforated plate. The upper cavity is arranged above the filter cloth. The lower cavity is arranged below the perforated plate. The upper and lower cavities are properly fixed to form a sealed space. In addition, a feed inlet is arranged on the upper surface of the upper cavity and a feed outlet is arranged on the lower surface of the lower cavity. A filter screen is further arranged between the filter cloth and the perforated plate. The device not only has a simple structure, but also improves the filtering effect greatly.
Description
Technical field
The utility model relates to a kind of filter.
Background technology
In order to remove the foreign matter in aqueous raw material, intermediate products or the final products, fabric filter cloth such as be widely used at a lot of industrial circles plain weave, twill and filter materials such as adhesive-bonded fabric system filter cloth or papery filter paper filter.
During filtration,, generally be upper reaches pressurization from filter material in order to improve the rate of filtration, the dirty vacuum draw of using.But; The intensity of the filter material of fabric filter cloth and adhesive-bonded fabric filter cloth or papery filter paper etc. a little less than; Therefore filter material can be out of shape or breaks because of unable to bear pressure and pull of vacuum, so the general porous plates such as metal system perforated metal of withstanding moulding pressure and pull of vacuum in the filter material held support filter material.
In order to support the filter material of fabric filter cloth and adhesive-bonded fabric system filter cloth or papery filter paper etc.; The aperture opening ratio that porous plates such as metal perforated metal are general is 20～40%; Filter material on the porous plate directly contacts because of the surface beyond moulding pressure, pull of vacuum and the porous plate opening, and closely the filter material of contact portion is sealed and can't be filtered.Therefore, effective filtration area is the peristome area of porous plate, promptly reduces to 20～40% of the filter cloth gross area.This just needs big filter.Also have, general filter cloth all is disposable, causes a lot of materials, cost waste.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of filter, and this device is not only simple in structure, and can promote filter effect greatly.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of filter; Comprise upper cavity, lower chamber, filter cloth, porous plate; Said filter cloth is located on the said porous plate; Said upper cavity is located at said filter cloth top, and said lower chamber is located at said porous plate below, and said upper and lower cavity just can be fixed formation one enclosure space; Be provided with charging aperture at said upper cavity upper surface in addition, be provided with discharging opening, between said filter cloth and porous plate, also be provided with one deck filter screen at said lower chamber lower surface.Like this, can avoid filter cloth and the direct of porous plate to contact, thereby improve filter effect.
As the further improvement of the utility model, said upper and lower cavity is hemispherical; Said filter cloth, filter screen and porous plate are the toroidal identical with the bottom surface of said upper and lower cavity.
As the further improvement of the utility model, between said filter cloth and said upper cavity, be provided with first packing ring, between said filter screen and porous plate, be provided with second packing ring, between said porous plate and lower chamber, be provided with the 3rd packing ring.
As the further improvement of the utility model, said filter screen is the stainless steel metal silk screen.
As the further improvement of the utility model, the order number of said filter screen is 20 orders.
As the further improvement of the utility model, said filter cloth is that polyester material forms, and its order number is 380 orders.
As the further improvement of the utility model, said porous plate is stainless steel perforated metal, and its aperture is 5mm, and aperture opening ratio is 20%, and thickness is 4mm.
As the further improvement of the utility model, the maximum inner diameter of said upper and lower cavity is 350mm.
Further improvement as the utility model; Said upper and lower cavity just can be fixed the structure that forms an enclosure space: periphery is installed with upper flange in said upper cavity bottom; Said lower chamber upper periphery is installed with lower flange, and said upper and lower part flange is connected through at least two screws.
The beneficial effect of the utility model is: through one deck filter screen is set between filter cloth and porous plate, can prevents effectively that filter cloth and the direct of porous plate from contacting, thereby guarantee filter effect preferably.
