Description

Sludge concentrator filter sets

Technical field

It the utility model is related to a kind of sludge concentrator filter sets.

Background technology

At present, the sludge dewatering equipment species that China uses is more, main to be carried out in the form of flight extruding at dehydration Reason, in existing sewage disposal device, it is allowed to form cotton-shaped sludge after sewage is added into flocculant, reusing dewaterer will Separation of solid and liquid, the sludge solid content requirement of suitable dewaterer, will shadows significantly when sludge solid content is less than 1% between 1%~4% Ring the operating efficiency of sludge dewatering equipment.The thickener that the country uses is at the early-stage, such as belt thickener machine, formula of transferring shares thickener, Its common ground is high energy consumption, and volume is big, and noise is big, and efficiency is low, filter body not easy cleaning.

Conventional filter disc type sludge concentrator, it includes the dehydration main shaft being connected in concentration casing, on dehydration main shaft Multiple filter discs are installed, rotated by being dehydrated main shaft band dynamic filter, so that liquid flows down from the gap between filter disc, it is cotton-shaped Sludge from opposite side discharge.Existing filter disc is substantially disc-shaped, and support plate, filter disc and support plate are housed between adjacent filter disc Between form filtrate gap, there is the problem of solid-liquid separation effect difference in the filter sets of this structure, and filter sets be present Difficult cleaning of problem.

Utility model content

The technical problems to be solved in the utility model is to provide that a kind of concentrated effect is good, the sludge concentrator of filter disc easy cleaning Use filter sets.

In order to solve the above technical problems, the sludge concentrator filter sets provided are more on filter disc axle including being connected to Group filter sets, every group of filter sets include two pieces of filtering rotating disks, are installed with median filter between two filtering rotating disks, its structure is special Point is that the one side for filtering rotating disk is provided with locating dowel, another side is correspondingly provided with positioning boss, filters and is additionally provided with edge on rotating disk Multiple liquid pass holes of its ring cloth, two filter the positioning of another piece of filtering rotating disk of locating dowel face on one piece of filtering rotating disk in rotating disks Boss is set and the locating dowel of two pieces of filtering rotating disks is equipped with towards homonymy, and the thickness of median filter is less than between two filtering rotating disks Distance is blocked on the filtering rotating disk that locating dowel is set towards outside so that form flow liquid gap between median filter and filtering rotating disk Equipped with interval filter disc.

The thickness of the interval filter disc is less than the distance between adjacent two filtering rotating disks so that interval filter disc turns with filtering Flow liquid gap is formed between disk.

The median filter is disc-shaped, which is provided with along its ring cloth and the card clamped for locating dowel is inwardly recessed from lateral surface Groove, the diameter of median filter are less than the diameter of filtering rotating disk.

The interval filter disc is disc-shaped, which is provided with the jack for supplying locating dowel to clamp along its ring cloth, is spaced the diameter of filter disc More than the diameter of filtering rotating disk.

The outstanding outer circumference face for making filtering rotating disk in middle part in the outer circumference face of the filtering rotating disk is formed in Between two sections of inclined planes being inside contracted to both sides.

Filter the distance between the side surface for filtering rotating disk of the protuberance in the outer circumference face of rotating disk with setting locating dowel Less than the distance between another side surface of the protuberance and filtering rotating disk.

The locating dowel is provided with the recessed pockets being inwardly recessed.

After said structure, filter sets are fitted on the filter disc axle of thickener, filter disc axle drives filter sets to turn Move, the filtering in flow liquid gap and liquid pass hole of the aqueous sludge Jing Guo above-mentioned, liquid is from below above-mentioned gap and liquid pass hole Flow down, it is achieved thereby that concentration process.By the setting of above-mentioned flow liquid gap and liquid pass hole, concentrated effect greatly improves, and And can be got express developed, avoid the occurrence of sludge and silt phenomenon up.

In summary, the utility model has the advantages of good concentrated effect, filter disc easy cleaning.
