Abstract
The invention is concerned with the entirety type of polypropylene septum filter pad structure and the forming technics, it is: the central liner forms by the mould, the pressing machine and the plastic, the polypropylene septum slice forms by mould injection moulding, the hot plate welding machine equips the upper hot plate and bottom hot plate that can heat the sealing surface of the upper and bottom central liner, and the reverse of the upper and bottom polypropylene septum slice, finishes weld once, processes machining for septum filter pad sealing surface and each hole after the heat sizing. The advantages are: reduces cast; get lower water content of filter cake; finish weld once; avoid the stress concentration of the septum slice, extend the useful life of the septum slice.
Description
Technical field:
The present invention relates to a kind of integral polypropylene septum filter plate structure and forming technology, belong to membrane filter plate and make the field.
Background technology:
The patent No. 01278300.5, title " combined type polypropylene diaphragm filter disc ", this membrane filter plate mainly are made up of central layer, diaphragm and charging through hole; Wherein, be provided with the charging through hole at central layer and diaphragm middle part, central layer and diaphragm are one being bonded near the position of charging through hole and position, edge thereof.Its weak point: the one, there is the slit between central layer and diaphragm, thoroughly sterilization; The 2nd, be planar structure around diaphragm and sealing surface, charging aperture and the support rim, stress is concentrated and can't be solved, and when diaphragm squeezed maximum position, suffered tension was also very big, shortened the service life of diaphragm greatly; The 3rd, water conservancy diversion speed is slow, is unfavorable for that diaphragm back side press media is full of rapidly or release fast.
Summary of the invention:
Purpose of design: the weak point of avoiding background technology to exist, design a kind of seal bactericidal effect good, can overcome diaphragm stress effectively and concentrate the short deficiency of diaphragm life-span caused, and the integrated polypropylene diaphragm filter-plate structure and the forming technology that can help that diaphragm back side press media is full of rapidly or discharge fast.
Design: in order to realize above-mentioned purpose of design.1, integrated polypropylene diaphragm filter-plate once is welded by a center liner plate and two polypropylene diaphragms on structural design.Because integral structure does not have unnecessary slit, does not have split type required seal, special substance anchor clamps etc., that is to say there is not antihygienic dead angle, sterilization is more thorough, and adopts full polypropylene material, and the filter material range of application is wideer.2, all to adopt pp material be main material for center liner plate, diaphragm, purpose strengthens its intensity and toughening modifying, because it has that chemical resistance is good, temperature resistant range wide (10～90 ℃), fatigue life excellence, high temperature steam sterilization advantage, therefore polypropylene is as thermoplastic, have recuperability, more more convenient, more economical on the manufacturing diaphragm than rubber.3, around near sealing surface, charging aperture and support rim, adopt slope transition design at diaphragm, purpose is to concentrate for the stress of alleviating and eliminate herein, when making diaphragm squeeze maximum position, suffered herein tension is also minimum, prolongs the service life of diaphragm greatly.Be subjected to the polypropylene material elastic limit simultaneously, compare external no gradient infrastructure product, the squeezing stroke of the diaphragm that extended can obtain the thinner more filter cake of low-water-content that reaches on year-on-year basis.4, adopt contour uniform design at the positive filter point of diaphragm, compare like product, the rate of filtration of whole filtering surface, saturating liquid speed have uniformity.5, be furnished with the design of supporting small salient point at the diaphragm back side all around near sealing surface, purpose plays guide functions except that supporting diaphragm, help that diaphragm back side press media is full of rapidly or discharge fast, and be furnished with lower small salient point on the liner plate surface, center, mainly play guide functions.6, the polypropylene diaphragm blank adopts injection molded.The blank sealing surface adopts saturating empty design, and purpose reduces contraction distortion, does not need plane processing before welding.The center liner plate adopts press forming, and sealing surface does not need plane processing before welding.Compare product in the past, saved processing step.Hot plate welding is met sb. at the airport and is furnished with two heating plates up and down, can heat simultaneously the upper and lower sealing surface of liner plate and the upper and lower diaphragm back side, and welding is once finished.After the thermal finalization, again membrane filter plate sealing surface and each hole are carried out processes.
Technical scheme 1: integrated polypropylene diaphragm filter-plate structure, it comprises center liner plate (2) and polypropylene diaphragm filter disc (1,3), two polypropylene diaphragm filter discs (1,3) are welded with center liner plate (2) two sides respectively.
Technical scheme 2: integrated polypropylene diaphragm filter-plate manufacture craft, the center liner plate adopts mould, forcing press and plastics press forming, the polypropylene diaphragm blank adopts mold injection to be shaped, hot plate welding is met sb. at the airport and is furnished with two heating plates up and down, can heat simultaneously the upper and lower sealing surface of center liner plate and the upper and lower polypropylene diaphragm back side, welding is once finished, and after the thermal finalization, again membrane filter plate sealing surface and each hole is carried out processes.
The present invention compares with background technology, and the one, the integrated polypropylene diaphragm filter disc can be used with common filter plate, reduces investment cost; The 2nd, whole filter press adapted integrated polypropylene diaphragm filter disc can obtain lower filter cake moisture content; The 3rd, hot plate welding is met sb. at the airport and is furnished with two heating plates up and down, can heat simultaneously the upper and lower sealing surface of liner plate and the upper and lower diaphragm back side, and welding is once finished, and few welding once; The 4th, eliminated diaphragm stress and concentrated, prolonged the service life of diaphragm; The 5th, various forms such as charging during the membrane filter plate feeding manner can adopt, upward charging, angle charging, charging down, the outer charging of plate, convenient different filter materials are selected for use.
Description of drawings:
Fig. 1 is the schematic diagram of integrated polypropylene diaphragm filter-plate structure.
The specific embodiment:
Embodiment 1: with reference to accompanying drawing 1.Integrated polypropylene diaphragm filter-plate structure, it comprises center liner plate 2 and polypropylene diaphragm filter disc 1 and 3, two polypropylene diaphragm filter discs 1 and 3 are welded with center liner plate 2 two sides respectively, polypropylene diaphragm filter disc 1 and 3 is being designed to transitional slope near the polypropylene diaphragm filter disc around sealing surface 10, charging aperture 11 and the brace table 5, polypropylene diaphragm filter disc 1 and 3 positive filter points 8 adopt contour uniform, the polypropylene diaphragm filter disc 1 and 3 back sides are near around the sealing surface, be furnished with and support small salient point 9, the center is furnished with lower small salient point 6 on the liner plate surface.Above-mentioned diaphragm 1 and 3 structure adopt mould, plastics extrusion device and the injection mo(u)lding of vertical pressure mechanism.Center liner plate 2 adopts mold injection molding.
