Description
Technical field
The utility model relates to technical field of sewage, particularly relates to boats and ships sewage pre-treatment device.Being mainly used in boats and ships sanitary sewage disposal, is one of important component part in the pretreating process of sanitary sewage front end.
Background technology
On boats and ships, the water yield of sanitary sewage and water quality are along with time, daily life system rule and changing.The change of the water yield and water quality makes treatment facility can not run under the process conditions of the best, even makes equipment work, needs to arrange sewage collection equipment for this reason, regulate the water yield and water quality time serious.
In Domestic sewage collecting device, pretreating process is the difficult point in ship sewage treatment field always, the pre-device of raw sewage is that simple to do a debris retaining graticule mesh or grid at water inlet blue, for retaining the bulk foreign material in sewage, other are if sheet, cigarette end, paper fiber are through in water hole inflow subsequent processing device, and its pretreating effect is general.Sheet in sewage, cigarette end, paper fiber is very large on the impact of subsequent treatment process, whole sewage-treatment plant is after the operation of long-term a period of time, a large amount of impurity (sheets is stored in sewage-treatment plant, cigarette end, paper fiber) and mud, and traditional sewage pre-treatment device does not process inanimate matter impurity such as the paper fibers precipitated, cause in the space of certain volume, the density of the inanimate matter impurity such as paper fiber is more and more come greatly, and the concentration of effective activated sludge reduces on the contrary in disposing of sewage simultaneously, greatly have impact on the biochemical effects in pretreatment unit, the device impact of increase on follow-up employing membrane biological reactor process of paper fibre density is more serious simultaneously, a large amount of paper fiber scum silica frost is attached to the surface of film silk, As time goes on, the direct aquifer yield affecting film silk, and strengthen giving film silk cleaning difficulty.
Summary of the invention
For the shortcoming of prior art, the purpose of this utility model is to provide a kind of boats and ships sewage pre-treatment device.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of boats and ships sewage pre-treatment device, comprise the first stillpot and the second stillpot, first stillpot bottom is the first slag storage region of inversed taper platform shape, second stillpot bottom is the second slag storage region of inversed taper platform shape, respectively by valve bottom first slag storage region and the second slag storage region, with be connected mud discharging mouth, first delivery port is arranged at the first stillpot top, second water inlet is arranged at the second stillpot bottom, first delivery port is communicated with the second water inlet, mozzle is placed with in the middle of first stillpot, described mozzle top is water inlet, inclined plate sedimentation device is placed with in described second stillpot, discharge outlet is arranged at the second stillpot top.
Further:
Described mozzle lower end can be flared structure, spreads to facilitate current direction surrounding.
Described first stillpot and the second stillpot can be connect body structure, and what centre can be separated to form the first stillpot and the second stillpot with flow-stopping plate is communicated with district.
The swash plate of described inclined plate sedimentation device adopts anticorrosive material to make, and mounting inclination angle degree can be 50o ~ 70o.
Described first stillpot and the second stillpot can be hollow cylindrical.
Described first stillpot and the second stillpot can be hollow four prism types.
The beneficial effects of the utility model are: adopt perpendicular stream precipitation+counterflow tilted plate precipitate combination, effectively sheet, cigarette end, paper fiber-like inanimate matter impurity can be carried out floating scarfing cinder and precipitation deslagging, reduce the inanimate matter impurity such as sheet, cigarette end, paper fiber to the impact of subsequent treatment process.Processing procedure is stablized, and affect little by vessel motion, practicality is high, effectively solves the technical problem that traditional boats and ships sewage collection equipment exists.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is the structural representation of the utility model first embodiment.
Fig. 2 is the structural representation of the utility model second embodiment.
Detailed description of the invention
See accompanying drawing, a kind of boats and ships sewage pre-treatment device of the utility model, it is characterized in that: comprise the first stillpot 1 and the second stillpot 3, first stillpot 1 bottom is the first slag storage region 2 of inversed taper platform shape, second stillpot 3 bottom is the second slag storage region 4 of inversed taper platform shape, respectively by valve 11 bottom first slag storage region 2 and the second slag storage region 4, 12 be connected mud discharging mouth 13, first delivery port 9 is arranged at the first stillpot 1 top, second water inlet 10 is arranged at the second stillpot bottom, first delivery port 9 is communicated with the second water inlet 10, mozzle 5 is placed with in the middle of first stillpot 1, described mozzle 5 top is water inlet 14, inclined plate sedimentation device 6 is placed with in described second stillpot 3, discharge outlet 15 is arranged at the second stillpot 3 top.
In embodiment of the present utility model:
Described mozzle 5 lower end is flared structure, spreads to facilitate current direction surrounding.
Described first stillpot 1 and the second stillpot 3 connect body structure, and centre is separated with flow-stopping plate 7, makes to form one between the first stillpot 1 and the second stillpot 3 and be communicated with district 8.
The swash plate of described inclined plate sedimentation device 6 adopts anticorrosive material to make, and mounting inclination angle degree is 50o ~ 70o.
In the first embodiment of the present utility model, described first stillpot 1 and the second stillpot 3 are hollow cylindrical.
In the second embodiment of the present utility model, described first stillpot 1 and the second stillpot 3 are hollow four prism types.
During work, pending sewage enters the first stillpot 1 from mozzle 5 top water inlet 14, tubaeform to the first stillpot 1 surrounding diffusion bottom mozzle 5, the foreign material that the paper fiber geometric ratio anharmonic ratio water in sewage is large are deposited in bottom the first stillpot 1, and the foreign material of precipitation are discharged by mud discharging mouth 13.The foreign material that sheet, cigarette end, shell geometric ratio anharmonic ratio water are light float and are gathered on the first stillpot 1 top water surface, are regularly cleared up by operator.Sewage after the first stillpot 1 initial gross separation foreign material flows to the second water inlet 10 bottom the second stillpot 3 by the first stillpot 1 top first delivery port 9, reduce in this effluent flow rate, the paper fiber that proportion is larger than water is deposited in bottom the second slag storage region 4, sewage further passs through inclined plate sedimentation device 6 and sails against the current, proportion tiny foreign material more heavier than water are deposited on the swash plate of inclined plate sedimentation device 6, foreign material are cumulative when total force exceedes buoyancy, foreign material are slipped to bottom the second slag storage region 4 from swash plate, sediment miscellaneous object is discharged by the mud discharging mouth bottom the second slag storage region 4.Clear water after sloping plate deposition enters sewage aftertreatment device through discharge outlet 15 discharge and carries out advanced treating.
