The press board is an annular board, the bottom board is an annular board, the inner surface of the firing filter screen is provided with supporting rings evenly along the axial direction, the inner surface of the firing filter screen among the supporting rings is provided with supporting strips evenly along the circumference direction, and the firing filter screen, the firing bottom screen, the frame, the supporting rings, the supporting strips, the pressing ring, the press board, the bottom board, an annular flange and the bolts are made of corrosion-resistant stainless steel. The filter device is mainly used for filtration of mass flow having corrosion media.
Description
Technical field:
The utility model relates to a kind of isolation technics, particularly a kind of filter.
Background technology:
Wire netting, filter felt or pottery etc. at the filter material normal operation of high temperature (450 °), high pressure (21MPa) and corrosion-resistant condition and large traffic filtering device, adopt inner frame single-layer metal net and overall structure, when filter net jam seriously need be changed, can only integral replacing, waste is large.
Summary of the invention:
It is large, high temperature resistant and corrosion resistance is good, easy cleaning and maintain and replace filter screen a kind of filter easily that the purpose of this utility model provides a kind of circulation filter capacity.The technical scheme that realizes the utility model purpose is, a kind of filter, comprise filter screen and skeleton, it is characterized in that: described filter screen is that the multi-layer sintering filter screen places on the inner surface of circular framework, make it to be fixed as one by bolt, the upper end of above-mentioned circular framework is connected with flange, the inner surface of above-mentioned sintering filter screen lower port is provided with hold-down ring, by bolt hold-down ring and sintering filter screen are fixed, circular sintering spacer screen places between pressing plate and the base plate, make it to be fixed as one by bolt, this pressing plate, spacer screen and base plate place on the inner surface of above-mentioned hold-down ring upper end, be integrated by being welded and fixed, above-mentioned pressing plate is the annular version, above-mentioned base plate is annular slab or is uniform porose circular slab on the plate, be evenly equipped with vertically support ring on the inner surface of above-mentioned sintering filter screen, the edge circumferentially is evenly equipped with support bar on the inner surface of the sintering filter screen between the support ring, above-mentioned support ring and support bar are bolted on the sintering filter screen, above-mentioned sintering filter screen, the sintering spacer screen, skeleton, support ring, support bar, hold-down ring, pressing plate, base plate, annular flange and bolt are to be made by corrosion resistant stainless steel.The nut of described bolt and bolt are provided with split pin or sheathed elastic washer on bolt.The mutual stagger arrangement of abutment joint of each the metafiltration net in the described multi-layer sintering filter screen.The utility model has compared with the prior art that high temperature resistant and corrosion resistance is good, the filter screen of easy cleaning and large traffic filtering can be changed separately, reduces the remarkable advantage that the multistorey strainer mesh seam is easily blocked.
Description of drawings:
Fig. 1 is the structural representation of the utility model filter, and Fig. 2 is the A place partial enlarged drawing of Fig. 1.
The specific embodiment:
With the following Examples the utility model is elaborated, skeleton of the present utility model is outer skeleton, this skeleton is made by the corrosion resistant plate of corrosion resistance and good, leave onboard different apertures and different percent openings according to the needs that filter, this plate is welded into circular framework 3 through rolling up circle, filter screen 4 is made by three layers of stainless steel cloth sintering, be fixed on by bolt 5 on the inner surface of above-mentioned skeleton, the upper port of the screen pack of above-mentioned circle is provided with flange 2 and is connected by welding and filter screen, and handle 1 is welded on the upper surface of this flange.Be provided with annular hold-down ring 8 in the lower port of the screen pack of above-mentioned circle, lower end with bolt and screen pack is connected, the circular bottom plate that matches with the hold-down ring inner surface of above-mentioned annular, spacer screen and pressing plate are fixed as one the three to place the upper end of above-mentioned hold-down ring by integrally welded by bolt, above-mentioned spacer screen is that three layers of stainless (steel) wire sintering form, the top of this spacer screen is pressing plate, this pressing plate is that stainless steel is made, uniform porose on it, the below of above-mentioned spacer screen is base plate, this base plate can be the plectane in annular bottom plate or uniform hole, in order to strengthen the strength and stiffness of circular screen pack, on the inner surface of screen pack, be evenly equipped with vertically a plurality of support rings 6, by bolt support ring and screen pack and skeleton are fixed as one, the edge circumferentially is evenly equipped with support bar 7 on the screen pack inner surface between the above-mentioned support ring, make support bar by bolt, screen pack and skeleton are fixed as one, and in order to prevent above-mentioned each bolt looseness, adopt on bolt and the nut and wear split pin or the measure of opening elastic washer is set.The upper port of above-mentioned screen pack is not established filter screen.
The multiple layer metal net that the utility model adopts is three layers of sintering filter screen, and the abutment joint of each layer wire netting staggers mutually, i.e. abutment joint non-overlapping, and this structure is better to rigidity, intensity and the strainability of net.
Said structure of the present utility model is specially adapted to the medium that large flow, high temperature and high pressure power have corrosion, both be applicable to Separation of Solid and Liquid, also separating of available gas and solid, this structure can be changed separately filter screen and not scrap the parts such as skeleton, support ring, support bar.
