Abstract
The present invention relates to an ultra high molecular weight polyethylene filter press plate, particularly to a material thereof and a structure thereof, which belongs to a component part of a filter press. The present invention is prepared from new materials, namely ultra high molecular weight polyethylene materials, and comprises a filter plate and two filter cloth pressing rings. The weight of the filter press plate is about one sixth of that of a cast-iron filter plate, and the life is improved by more than 11 times. The present invention has very high compression resistance and impact resistance, has the advantages of flexible operation and convenient maintenance, lightens the labor intensity of workers, greatly increases the work efficiency, and reduces the maintenance cost.
Description
The invention belongs to the building block of filter press, relate to its material and structure.
The press filtration plate is the main working parts of filter press, its good and bad work effect that directly influences filter press.At present the press filtration plate of using be cylinder iron, materials such as rubber, polypropylene plastics make, and require characteristics such as high resistance to compression, high impact-resistant, in light weight, ESCR because of the press filtration plate, the press filtration plate that above-mentioned material is made does not possess above-mentioned condition.As cast iron compression strength greater than 26Kg/cm
2Just rupture, spheroidal graphite cast-iron is no more than 120Kg/cm
2Elastomeric material is yielding and come unstuck, and polypropylene plastics compression strength is low, yielding.On the other hand, the structure of the press filtration plate that uses is very unreasonable at present, and flow distribution is inhomogeneous, thereby causes internal stress also inhomogeneous, the yielding damage of press filtration plate, and its spoilage reaches 6%/thousand time.Therefore, improving press filtration plate performance is the problem that presses for solution.
The objective of the invention is to change the material and the structure of press filtration plate, make its life-span long, in light weight, have high resistance to compression, high impact-resistant, an ESCR etc.
The object of the present invention is achieved like this.The press filtration plate is made of ultra-high molecular weight polyethylene (UHMW-PE) material.The press filtration plate is made of filter plate and two worry cloth trim rings, and the filter cloth trim ring is contained in the position of filter plate two sides centre bore, and the filter cloth trim ring is an annular, and one side has a bulge loop along the endoporus edge, and another side has 3 with convex platform.Filter cloth trim ring bulge loop external diameter is consistent with the filter plate center bore.
Advantage of the present invention is: owing to make the change of material, weight greatly alleviates, and is about the sixth of cast iron filter plate.Life-span improves more than ten times, and resistance to compression can be brought up to 300Kg/cm
2More than, impact strength is greater than 140Kg/cm
2Below do not rupture.Because the variation of structure has effectively prevented the internal stress distortion of filter plate, helps the quick location of filter plate, has improved the tightness between filter plate, has reduced the loss of filter cloth between the press filtration plate.The press filtration plate is assemblied on the filter press, has improved operating efficiency greatly, has alleviated labour intensity, and flexible operation is easy to maintenance, has saved fund.
Concrete structure of the present invention and enforcement are provided by the following drawings and embodiment.
Fig. 1 is a press filtration plate front elevation.
Fig. 2 is a press filtration plate vertical view cutaway drawing.
Fig. 3 is a filter cloth trim ring front elevation.
Fig. 4 is a filter cloth trim ring vertical view cutaway drawing.
The press filtration plate comprises filter plate (1) and 2 filter cloth trim rings (2), all is with ultra-high molecular weight polyethylene (UHMW-PE) material, touches the compression technology moulding with the oil heating.The shape of filter plate (1) is similar to former cast iron filter plate shape, and the present invention respectively is equipped with a filter cloth circle (2) at its two face central hole locations.Boss on the filter cloth trim ring is designed to 4 and is advisable.When using filter press, up to a hundred blocks of press filtration plates are assemblied on the filter press, and adding one deck filter cloth seal between the press filtration plate can.
Claims (1)
1, a kind of super high molecular weight polyvinyl filter press machine filter plate, filter plate (1) and two filter cloth trim rings (2) by oily heating and mould pressing technological forming constitute, filter cloth trim ring (2) is contained in the position of filter plate (1) two sides centre bore, it is characterized in that, the filter cloth trim ring is an annular, it simultaneously has a bulge loop along the endoporus edge, and another side has four boss, and filter cloth trim ring bulge loop external diameter is consistent with the filter plate center bore.
