Abstract
The utility model provides a compressed sedimentation tank, comprising a sealed tank body, wherein a water inlet end is arranged at the top of the sealed tank body; inverted cone filter cloth is fixed at the lower part inside the sealed tank body and is used for filtering water; a rotating sludge scraper is arranged above the inverted cone filter cloth; sludge attached to the inverted cone filter cloth is scraped off through the rotating sludge scraper so that water can be filtered out; the bottom of the inverted cone filter cloth is connected with a blast aeration machine outside the sealed tank body through a connecting pipe and is used for increasing internal air pressure of the sealed tank body; the compressed sedimentation tank also comprises a sludge pump; the sludge pump is communicated with the connecting pipe; a water outlet is formed in the bottom of the sealed tank body, is formed below the inverted cone filter cloth and is used for discharging water.
Description
Technical field
The utility model relates to settlement of sewage processing technology field, refers in particular to compression precipitating tank.
Background technology
Sedimentation basin be generally before biochemistry, biochemical after or the structures of dosing pretreatment mud-water separation, mostly be the mud that separating particles is thinner.Before biochemistry, be called preliminary sedimentation tank, the mud inorganic constituents of precipitation is more, and moisture percentage in sewage sludge is lower with respect to second pond mud.Be positioned at biochemical sedimentation basin afterwards and be commonly referred to as second pond, mostly be organic sludge, moisture percentage in sewage sludge is higher.Being deposited in sewage disposal is a very important step, and the effect of precipitation is to remove suspension in water, for subsequent treatment ready.
Existing precipitation is natural sedimentation, or cohesion occurs or flocculate to precipitate by dosing.These precipitations are all to precipitate gradually by the weight of suspended particulate in sewage own.When displacement increases suddenly, precipitation not exclusively, impacts subsequent treatment.And more time-consuming, some sewage need to carry out pretreatment, overlong time and cause subsequent treatment disconnecting, draining peak period, causes sewage to be piled up, and causes and produces difficulty.Precipitating sludge moisture content is high.
Summary of the invention
The technical problems to be solved in the utility model, is to provide compression precipitating tank, solves the problem that existing settling velocity is slow, precipitating sludge moisture content is high.
The utility model is achieved in that
Compression precipitating tank, comprises sealed shell of tank, and the top of sealed shell of tank has water inlet end, and an inverted-cone shape filter cloth is fixed in below, sealed shell of tank inside, for drainage; Inverted-cone shape filter cloth top is provided with rotation and scrapes trowel, scrapes trowel strike off the mud sticking on inverted-cone shape filter cloth by rotation, is convenient to water and leaches; Inverted-cone shape filter cloth bottom is connected with the blast aeration machine outside sealed shell of tank by tube connector, for increasing sealed shell of tank air pressure inside; Also comprise sludge pump, described sludge pump is communicated with described tube connector; Sealed shell of tank bottom has a delivery port, and delivery port is positioned at inverted-cone shape filter cloth below, for draining.
The utility model has the advantage of: the utility model is by increasing air pressure inside, and compression sewage makes the quick coagulative precipitation of mud, and effective effluent sewerage, and the moisture content of discharging mud is lower, reaches high efficiency and time conservation object.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Refer to shown in Fig. 1, compression precipitating tank, comprises sealed shell of tank 1, and the top of sealed shell of tank 1 has water inlet end 2, and an inverted-cone shape filter cloth 3 is fixed in the inner below of sealed shell of tank 1, for drainage; Inverted-cone shape filter cloth 3 tops are provided with rotation and scrape trowel 4, scrape trowel 4 strike off the mud sticking on inverted-cone shape filter cloth 3 by rotation, are convenient to water and leach; Inverted-cone shape filter cloth 4 bottoms are connected with the blast aeration machine 6 outside sealed shell of tank by tube connector 5, for increasing sealed shell of tank 1 air pressure inside; Also comprise sludge pump 7, sludge pump 7 is communicated with tube connector 5; Sealed shell of tank bottom has a delivery port 8, and delivery port 8 is positioned at inverted-cone shape filter cloth 4 belows, for draining.
During concrete enforcement, preferably inverted-cone shape filter cloth 4 belows are installed one and equally with inverted-cone shape filter cloth 4 sizes are had a stainless steel support member 9 being covered with compared with large through-hole, the utility model in use, sewage is from water inlet end 2 water inlets, after filling sealed shell of tank 1, stop into water, carry out blast aeration (if having dosing can serve as stirring action before water inlet), and open rotation and scrape driven by motor that trowel 4 connects and scrape trowel rotation and strike off the mud on inverted-cone shape filter cloth 3, prevent because sludgd deposition obstruction inverted-cone shape filter cloth 3 cannot pass through sewage, and can make like this sewage by inverted-cone shape filter cloth 3, from delivery port 8, discharge fast.Along with air blast air pressure increases gradually, compression mud, causes quick cohesion, and clear water leaches.After appropriate time, turn off the blast.When clear water leaches when less, open sludge pump 7 mud is got rid of from bottom, and can again intake.Convenience and high-efficiency.
The above embodiment, it is better embodiment of the present utility model, be not to limit the utility model practical range, the equivalence of doing according to structure, feature and principle described in the utility model claim therefore all changes or modifies, and all should comprise in the utility model patent claim.
