Conical lower portion tank
Technical field
The utility model relates to a kind of conical lower portion tank for sewage disposal.
Background technology
The tank of different size can be used in sewage disposal process, more or less all can residual fraction dirt and harmful substance in bottom during the water of traditional tank in emptying tank, owing to all can produce the harmful substance containing some free settlings such as heavy metal, suspension in industries such as metallurgy, plating, mining, chemical industry, livestock and poultry breeding industries, tank can be corroded, puzzlement is brought to the sewage disposal in later stage, the operation of equipment, increases maintenance cost and the operation cost of tank.
Summary of the invention
The utility model object is the deficiency overcoming above-mentioned prior art, provides a kind of compact conformation, effectively can get rid of the residual conical lower portion tank of bottom of gullet sediment.
The utility model comprises water inlet, overfall, delivery port, top board, antetheca, rear wall, sidewall, reinforcement, bottom surface swash plate and support; Water inlet is located on tank top board, and overfall is located at above tank sidewall, and overfall is apart from tank top board distance 30-50mm place, and delivery port is located at rectangular pyramid drift angle place bottom antetheca, and each mouth of a river is connected by ring flange with pipeline.Bottom rectangular pyramid is made up of antetheca, a ground swash plate B and two piece symmetrical bottom surface swash plate A, hydromechanical principle design is adopted to be irregular rectangular pyramid, wherein, antetheca is perpendicular to tank top board, bottom surface swash plate A is vertical with antetheca and become 60 ° of angles with sidewall, and bottom surface swash plate B becomes 60 ° of angles and intersects at antetheca drift angle water outlet with antetheca with antetheca; Support adopts that channel-section steel is uniform is welded in tank surrounding, and be provided with reinforcement between tank antetheca, rear wall, sidewall, reinforcement adopts angle steel cross structure.
Sewage first injects tank by water inlet, is flowed out enter next process after filling by delivery port; In tank after filling, due to bottom of gullet to be inclination angle the be special-shaped rectangular pyramid of 60 °, suspension, mud etc. in the sewage of tank inside can be deposited in the rectangular pyramid of bottom of gullet voluntarily, come together in the drift angle place of rectangular pyramid, are then discharged by delivery port; When the water of water inlet enters tank always, for preventing sewage overflows, tank is provided with overfall, sewage can be flowed out by overfall.
The utility model structural design is compact, is 60 ° according to the inclined bottom surface plate of the bottom of gullet rectangular pyramid of fluid mechanical design and antetheca angle; The precipitums such as mud are collected and are got rid of successful; Entery and delivery port place is all provided with flange, is convenient to the installation of pipeline; Can be used on each processing unit, as former tank, mixing channel, stillpot hollow membrane tank etc.
