Abstract

The utility model relates to a press filter for lees and stuff used for lees and stuff deep-processing in fermenting industry. The utility model is composed of a large drum and a small drum which are concentric, the inner wall of the large drum is provided with a diaphragm, the outer wall of the small drum is provided with a filter layer, the diaphragm can extrude and dewater materials in the inner drum by inflation. The utility model has the advantages of simple structure, high dehydration rate, cost saving and reliable use.

Description

Cylinder type variable volume diaphragm filter press

The utility model relates to the equipment of the poor object depth processing of a kind of fermentation industry, its objective is the water content that reduces poor thing, be processed into powder granulous poultry and use feed so that dry.

At present, known poor material filter plant is concluded and to be got up to be divided into three kinds, and 1, plate and frame; 2, cloth bag type; 3, centrifugal.The shortcoming of plate and frame wherein: 1, the unit treatment capacity is unsuitable excessive; 2, device structure complexity; 3, filtering rate is low; 4, accessory rapid wear.The cloth bag type shortcoming: 1, the unit treatment capacity is little; 2, cloth bag rapid wear; 3, the processing cost height of unit weight; 4, the equipment work environment is poor; 5, labour intensity is big.Centrifugal shortcoming: 1, the treatment capacity of unit time is little; 2, device structure complexity; 3, required drive is big; 4, the processing cost height of unit weight; 5, dehydration rate is low.More than the shortcoming of three kinds of equipment are present fermentation industry biggest obstacles of using of large-scale promotion all sidedly.

The purpose of this utility model provides a kind of: 1, the unit treatment capacity is big; 2, device structure is simple; 3, required drive is low; 4, the tooling cost of unit weight is low; 5, maintenance of equipment is simple.

The purpose of this utility model is achieved in that utilizes two concentric garden buckets of size, and drum is selected proper proportion with keg diameter and length according to the material situation.The barrier film that on the inwall of drum, adheres to one deck colloidality stretch-proof material.Near of the flange flange sealing of bung place barrier film with drum.Be provided with air inlet port on the drum outer wall, purpose is after squeezing into air pressure, impels inwardly bucket place extruding of barrier film.On the keg outer wall, have the countless intensive uniform apertures of arranging.Adhere to the layer of metal support mesh on the aperture.Adhere to one deck filter cloth, aperture, support mesh on the support mesh, the unit order number of filter cloth can suitably be selected for use according to the situation of material.Wherein end at big garden bucket is provided with the flange connection of capping with the garden bucket, and the garden heart has Sliding bush, and size is supporting with the inner core central shaft.Have at the lowest part of interior bucket and to portal, its posticum coincide mutually with the capping posticum.The middle part of the material storing cavity between the big keg is provided with opening for feed, and its opening for feed matches with the capping opening for feed.The end that capping is arranged at keg is provided with scraper plate, and purpose is when keg is drawn out, and scraper plate scrapes material.The bucket the other end has a capping equally in the garden, and this capping is an one with an interior bucket and an interior bucket center bolt, and there is rubber seal at the capping edge with outer bucket contact part.The concentricity screw rod of central shaft all should be furnished with keyway on the length central shaft greater than bucket, and the rear portion of central shaft (i.e. bucket long after) keyway distributes around 180 ° of rotations of between centers.The outer nut that has relative fixed to rotate on the center bolt, the rotation of outer nut has driven by motor by variator, its objective is, bucket is pulled out from outer bucket by level in motor rotates drive nut, nut drive center bolt, central shaft when the inside of the drum that moves out of, is done 180 ° of rotations of between centers by the keyway bundle.The working process of this equipment is achieved in that when poor material enters material storing cavity by opening for feed close opening for feed, pressurized air is chewed by gas and entered barrier film, impels inwardly bucket expansion of barrier film.Material in the extruding material storing cavity.Material is under membranous extruding, and filtrate is promptly flowed out by filter cloth, support mesh, aperture, posticum.After continuing the extruding certain hour, when promptly the filter residue water content is reduced to 40-50%, discharge the pressurized air barrier film and reset.Start motor, the nut rotation, interior bucket is pulled out.Material is taken out of with interior bucket and material scraping plate.The motor counter-rotating, interior bucket resets, and waits for the next work period.

Owing to adopted above scheme, the utility model to accomplish, 1, the unit treatment capacity is big, 2, device structure is simple; 3, required drive is little; 4, the tooling cost of unit weight is low; 5, maintenance of equipment is simple; 6, dehydration rate height.
