Description

For the spiral filter centrifugal that sewage solid separates

Technical field

This utility model relates to the spiral filter centrifugal that sewage solid separates, and is applied to the liquid dung cleaning of urbanization manure pit, by coordinating suction-type sewer scavenger, it is possible to septic tank contamination and sewage carry out solid-liquid separation quick, lasting, efficient and processes。

Background technology

Along with China's city size is expanded rapidly and population increase and gathering; the conventional process pattern of existing city septic tank contamination, equipment and technology; being difficult in adapt under new normality environmental quality and the requirement of protection, septic tank contamination processes the contradiction with urban modernization construction and development。For a long time, field of sanitation lacks advanced person, specialized anaerobic tank excrement dirt harmless treatment device。Septic tank contamination and sewage are because intractability is big, cost is high, be prone to blocking pipeline, and general municipal wastewater treatment plant does not accept process of dissolving, and causes the excrement dirt that city is drawn out clearly to dissolve nowhere, has to transport refuse landfill to, be mixed into house refuse and fill together；Sewage directly discharges urban sewage pipeline, causes being frequently occluded of urban sewage pipe system and the eutrophication of rivers and lakes water quality。Severe contamination is not only caused in reservoir area, soot by this, too increases landfill operation difficulty；Exist transportation is run simultaneously and emit, water clock, the contaminated environment factor such as spill；And long-distance transportation cost is high, time-consuming effort, operation economic pressures are big；Additionally, sewage directly discharges, polluted source and subsoil water。Septic tank contamination viscosity is big, fibre material is many, particle size distribution scope is wide, overwhelming majority existing weaponry and equipment is processing the relatively big material with granule of viscosity, particularly during fibre material, input concentration is slightly larger can be blocked again, is generally difficult to smoothly complete one-stop operation, filter operation need to be interrupted, change filter element or take out cleaning, not only time-consuming but also bothersome, affect treatment effeciency；And owing to metal screen gap is only small, during flushing, relatively difficult water consumption is very big。

Summary of the invention

This utility model is to solve easily to block in existing dirt separation process equipment, need to change or take out filter element to clean, interrupt filter operation, the problem that treatment effeciency is low, effectively promote septic tank contamination fast throughput, realize solid-liquid separation on the spot, reduce the dependency to garbage loading embeading Treatment stations and sewage treatment plant, reduce comprehensive operation cost, it is provided that a kind of spiral filter centrifugal separated for sewage solid。

The technical scheme that the utility model proposes is: the spiral filter centrifugal separated for sewage solid, including frame, two separate motors and travelling gear, solid-state bearing；Motor one connects travelling gear one and drives helical blade, motor two connects the travelling gear two of sieve bucket side and drives sieve bucket, sieve bucket two ends are arranged in frame, Shaftless spiral blade and sieve bucket are arranged on installation frame by coaxial bearing, sieve bucket two ends have solid-state bearing one and solid-state bearing two respectively, having helical blade, main shaft in sieve bucket, sieve bucket cylinder gathers sieve aperture；Shaftless spiral blade one end connection frame, the other end connects bearing baffle；Shaftless spiral blade connects vacuum pump；Dirt sucking tube is connected with helical blade by charging aperture；Bearing baffle is arranged in frame；One end of helical blade is equipped with solid-state bearing three.。

Motor one and motor two select hydraulic motor, independent control；May be used without motor (electric notor), two motor rotary speed differences are maintained at certain limit, by the rotating speed of adjustable screw blade and sieve bucket and speed difference, control the extruding transporting velocity of sieve bucket centrifugal force and helical blade。

Gap between Shaftless spiral blade and sieve bucket is less than screen size, and screen size, by separating the design of liquid contained particulate matters size requirements, plays centrifugal filtration function by high-speed rotation。Scrape and cut sieve aperture clamping stagnation thing, clear up inboard wall of riddle drum and the spoon of blade of continuous and derivable and spiral enveloping surface, it is ensured that the conveying of solid waste, it is to avoid the clamping stagnation of helical blade。

Shaftless spiral blade is with rotational conveyance under the traction of spiral for ease of material, in case sanitary towel in anaerobic tank, plastic strip, feather, rope, the curling balling-up conglomeration between spiral shell rib and charging aperture of the isometric fibre material of hair, the entrance of blocking material。

Solid-state bearing adopts the solid lubricant of polytetrafluoroethylmaterial material etc directly to process, it is to avoid the problems such as corrosion are polluted in the abrasion of common rolling bearing。

Helical blade used and screen drum are the helical blade through sandblasting and tungsten carbide thermal spraying treatment and screen drum, can reduce or avoid the abrasion of helical blade and screen drum。

Compared with prior art, the present utility model has the positive effect that this utility model:

1, the mode that helical blade combines with sieve bucket is adopted to carry out the solid-liquid separation of dirt and sewage, the rotating speed with adjustable screw blade and sieve bucket and speed difference is independently driven respectively through motor, control the extruding transporting velocity of sieve bucket centrifugal force and helical blade, while solid-liquid separation, solid waste is transported to discharging opening, simple in construction, operation is efficient；

2, the gap of helical blade and sieve bucket is less than screen size, scrape and cut sieve aperture clamping stagnation thing, clear up inboard wall of riddle drum and the spoon of blade of continuous and derivable and spiral enveloping surface, helical blade is stuck and sieves the problem that the sieve aperture of bucket is blocked to make it not easily occur, it is ensured that the effect of solid-liquid separation；

3, helical blade is shaftless, it is easy to material with rotational conveyance under the traction of spiral, in case sanitary towel in anaerobic tank, plastic strip, feather, rope, the curling balling-up conglomeration between spiral shell rib and charging aperture of the isometric fibre material of hair, twine the problem scratching helical axis, it is prevented that blocking material enters；

4, bearing adopts solid lubricant (such as polytetrafluoroethylmaterial material, etc.) directly to process, it is to avoid etching problem is polluted in the abrasion of common rolling bearing；Helical blade and screen drum are carried out sandblasting tungsten carbide thermal spraying treatment, reduces or avoid the abrasion of blade and screen drum。
