Description
Technical field
The present invention relates to a kind of solid-liquid separation dehydration equipment, be specifically related to a kind of vacuum belt press filter.
Background technology
At food, papermaking, industries such as sugaring need be to food, paper pulp, sucrose mix juices etc. filter, and at metallurgy, chemical industry, papermaking, process hides, the alcohol sewage disposal, livestock culture, usually need the waste liquid and the waste residue of association are carried out environmental protection treatment in the industrial production such as urban catering rubbish, and first procedure of waste liquid and waste residue processing is carried out Separation of Solid and Liquid to it exactly, and be after carrying out Separation of Solid and Liquid, the moisture content of waste residue is low more, the utility that not only reclaims from waste liquid is more, and the also easier processing of waste residue, the cost of integrated treatment becomes lower, and obtainable economic benefit will be high more.In various dehydration equipments, owing to have and uninterruptedly to produce continuously, simple to operate, operation expense is low, characteristics such as solid-liquid separation efficiency height, at present, in above-mentioned industry production practices, used belt filter press both at home and abroad morely, it has played effect preferably in processing such as food, paper pulp, sucrose mix juices, and aspect the Separation of Solid and Liquid production of waste liquid and waste residue, various dehydration equipments have also been brought into play bigger effect.But the efficient of Separation of Solid and Liquid is still waiting further raising on the whole, and the water content of separating the back waste residue also has big gap from the requirement of subsequent treatment process, has not adapted to social development and resource has been made full use of the requirement that improves day by day with environmental protection.
In recent years in order to improve the efficient of Separation of Solid and Liquid, it should be noted that belt filter press has fast than existing a lot of equipment aspect Separation of Solid and Liquid, the characteristics of automation and continuous production process, so a lot of fields have begun it is applied in food, paper pulp, sucrose mix juices etc. filter, and at metallurgy, chemical industry, papermaking, process hides, the alcohol sewage disposal, livestock culture, in the Separation of Solid and Liquid in the industrial production such as urban catering rubbish, but still there are many weak points in present belt filter press aspect Separation of Solid and Liquid, for example, at the material that some is had certain viscosity, for example: fecula, during the Separation of Solid and Liquid of the organic waste residues of paper pulp and the contour fiber content of alcohol waste residue, the water content of waste residue can only be reduced to about 75%, it is to dry or biofermentation has all brought great difficulty that such waste residue water content is given following one treatment process.Trace it to its cause, mainly being the self structure design decision, it can't further reduce the water content of waste residue.Because waste residue is subjected to pressure roller high pressure when extruding entering the pair roller crush zone, quite a few flies at the moisture that is extruded the surface of waste residue and attaches on strainer not drippage, after waste residue loses pressure through the pair roller crush zone, because inner high fibrous elasticity structure, it will float on the surface again and the moisture suck-back that attaches on strainer goes back, thereby make the moisture content of waste residue be difficult to be effectively reduced.
In order to solve above-mentioned filter press in expressing process after the material decompression, thereby moisture is gone back to influence the problem of dehydrating effect again by the material suck-back, people improve existing filter press, the most tangible improvement is to have increased vacuum plant at filter press, 91226699.6) and " combined type vacuum belt press filtering machine " (patent No.: 95202832.8) for example Chinese patent discloses " vacuum belt press filtering machine " (patent No.: of people such as Chen Xijie invention, on the architecture basics of original belt filter press, increase by one to three vacuum pressure roller, make the interior material of strainer when being subjected to the extruding force of pressure roller, by the negative pressure of vacuum that forms in the vacuum pressure roller, make the moisture that floats on the material surface under pressure and attach on strainer be sucked into vacuum pressure roller inside, thereby further reduced the moisture of material after the press filtration, obtained certain effect.But still there is deficiency in above-mentioned two patents, be material in strainer by when squeezing, can form the trapezoidal filter cake of shape approximation, be that the thick middle both sides are thin, when the vacuum unit that connects the vacuum pressure roller is opened, when forming negative pressure of vacuum in the vacuum pressure roller, because the bed of material on filter cake both sides is very thin, just at first can be suctioned through by vacuum moment, a large amount of air just enters in the vacuum pressure roller from these both sides, promptly reduces the vacuum in the vacuum pressure roller, makes to be in the pressure roller middle part and only to be subjected to very little negative pressure than the filter cake of thickness portion, even be not subjected to negative pressure basically, so can't be suctioned through at all, owing to do not form path, the moisture in this part filter cake is not sucked away substantially yet, what be sucked away only is moisture in the very thin partial material in both sides, so the overall moisture content of material does not significantly reduce.
