Description

Novel decanter device for coal chemical wastewater treatment

The technical field is as follows:

the utility model relates to the technical field of water decanters, in particular to a novel water decanter device for treating coal chemical wastewater.

Background art:

the decanter is a device for periodically removing clear water adopted by SBR technology, and has the function of decanting the clear water from the surface of a static tank without stirring and precipitating to ensure the quality of the discharged water. The SBR process adopts intermittent reaction, water inlet, reaction, sedimentation and drainage are completed in the same tank, and a secondary sedimentation tank and sludge backflow equipment are not needed, so that the SBR process has the advantages of small occupied area, low investment, high efficiency, good effluent quality and the like; the existing decanter is mostly of a buoyancy type structure, a common mechanism of the decanter comprises a water tank, a buoyancy device, a hose and an overflow weir are sequentially designed in the water tank from top to bottom, the overflow weir is usually installed on the outer wall of the water tank, clean water enters the hose through an overflow hole on the hose and then is discharged from the overflow weir when the decanter is used, and the decanter of the structure generally has the following defects: 1. because the positions of the overflow weirs are fixed, and the quality of sewage in different batches is different, the precipitation amount of precipitates is also different, so that clear water cannot be completely discharged easily due to the fact that the positions of the overflow weirs are too high, and mud runs easily due to the fact that the positions of the overflow weirs are too low, and actual production requirements are difficult to meet; 2. The area of the water tank is large in general, and the overflow holes are easily blocked due to the large floating objects on the water surface.

The utility model has the following contents:

the utility model aims to provide a novel decanter device for treating coal chemical wastewater.

The utility model comprises the following contents: a novel decanter device for treating coal chemical wastewater comprises a water treatment tank which is horizontally arranged, wherein a drain pipe is arranged at the bottom of the water treatment tank, the drain pipe consists of a horizontal underground section and a vertically arranged water tank section, the underground section is positioned under the water treatment tank, the underground section is buried underground, the water tank section penetrates through a bottom plate of the water treatment tank and enters the water treatment tank, a folding hose is vertically arranged right above the water tank section, the folding hose sequentially consists of a folding section and a decanting straight pipe section from bottom to top, the folding section is connected with the water tank section, a plurality of decanting holes are formed in the outer wall of the decanting straight pipe section, a hollow floating ball is concentrically arranged at the top end of the decanting straight pipe section, and a cylindrical protective fence is vertically arranged in the water treatment tank, the bottom fixed mounting of safety fence is in on the bottom plate of water treatment pond, folding hose with the concentric being located of hollow floater in the safety fence set up annular spacing annular on the outer wall of hollow floater the safety fence upper level set up threaded through-hole, threaded through-hole in the spiro union have with spacing annular assorted stop screw is in the top both sides position homonymy of safety fence is provided with the pedestrian bridge, pedestrian bridge fixed mounting is in on the water treatment pond.

Furthermore, the clearance between the outer wall of the hollow floating ball and the inner diameter of the protective fence is smaller than 1 cm.

Furthermore, a cylindrical filter screen is sleeved outside the straight decanting pipe section.

The utility model has the beneficial effects that: the utility model has simple structure, the drain pipe (equivalent to an overflow weir) is designed below the water pool and buried underground, the phenomenon that clear water cannot be drained cleanly can not occur, the phenomenon of stemming can not occur, and the water treatment quality is obviously improved; the design has protective fence, can effectually block the surface of water floater and prevent that it from blockking up and strain the water hole, can also play fine stop device to hollow floater simultaneously, prevents that it from removing to other directions (avoid folding return bend to take place to drag outward promptly), improves folding hose's life, is worth using widely on a large scale.
