Abstract
The utility model is related to a kind of slag-draining devices of flotation tank upper layer body refuse, including dreg scraping buggy and mud layer water conservancy diversion weir plate, it is characterized in that：The dreg scraping buggy side is equipped with the idler wheel walked on the guide rail of pond, the dreg scraping buggy other side is connected with holder, cantilever tip is connected with rotation axis, scum board is slidably connected in rotation axis, the scum board surface is connected with steel wire rope, and the steel wire rope other end take-up pulley bonded with motor output shaft is connect.Advantageous effect：The utility model mud scraper will not take back body refuse in return path, and can pass through mud layer water conservancy diversion weir plate, and body refuse can substantially completely be discharged than before, not influence effluent quality.Mud scraper scrapes mud and works well, and enables to float on the problem of body refuse in flotation tank is normally discharged, avoids body refuse from getting deeper, slowly sink in pond, be entrained into outlet system with flow, influence effluent quality and occurs.
Description
Technical field
The utility model belongs to the slag-draining device of sewage treatment field more particularly to a kind of flotation tank upper layer body refuse.
Background technology
The deslagging of flotation tank upper layer body refuse is mainly operated by the cleaning shoe of Slag Scraping Device.Refer to attached drawing 3-4, cleaning shoe
5 with gravity drop hammer 8 in about an angle of 90 degrees degree weld, when cleaning shoe carries out scraping mud operation, gravity drop hammer holding horizontality, scum board due to
The gravity of gravity drop hammer vertically downward, is inserted into the water surface, and flotation tank upper layer body refuse is scraped to weir plate, body refuse is arranged by Parallel to the flow direction
Go out flotation tank.Attached drawing 4 is referred to, after scraping mud operation, gravity drop hammer touches holder in vertical state, and scum board is made due to gravity drop hammer
With being horizontal and be detached from the water surface.When taking the water surface to by dissolved air water due to the suspended particulate of sewage in flotation tank, the mud of formation
It containing medicaments such as flocculant and coagulant in slag blanket, often sticks on scum board, it is more than gravity drop hammer to make the weight of scum board
Weight, cause scum board is perpendicular in returning to road to move down, scum board then again can be inserted into the water surface, surface layer body refuse is had
Again flotation tank is taken back, effluent quality is influenced.The steel mud layer water conservancy diversion weir plate of existing flotation tank and flotation tank pool wall are horizontal simultaneously,
There is no the gradient so that a part of mud layer cannot be excluded with water conservancy diversion weir plate, affect the effluent quality of flotation tank.
Utility model content
Purpose of the utility model is to overcome the shortcomings of the above technology, and to provide a kind of deslagginves of flotation tank upper layer body refuse
Flotation tank slime layer can smoothly be scraped and be exported flotation tank, ensure that the water quality of flotation tank by device.
The utility model to achieve the above object, using following technical scheme：A kind of deslagging of flotation tank upper layer body refuse fills
It sets, including dreg scraping buggy and mud layer water conservancy diversion weir plate, it is characterized in that：The dreg scraping buggy side is equipped with the rolling walked on the guide rail of pond
Wheel, the dreg scraping buggy other side are connected with holder, and cantilever tip is connected with rotation axis, and scum board is slidably connected in rotation axis, described
Scum board surface is connected with steel wire rope, and the steel wire rope other end take-up pulley bonded with motor output shaft is connect.
The rectangular triangle in cross section of the mud layer water conservancy diversion weir plate, level right angle side and bevel edge angle are 18.4 °.
Advantageous effect：Compared with prior art, the utility model mud scraper will not take back body refuse in return path, and
Mud layer water conservancy diversion weir plate can be passed through, body refuse can substantially completely be discharged than before, not influence effluent quality.Mud scraper scrapes mud effect
Fruit is good, enables to float on the body refuse in flotation tank and is normally discharged, avoid body refuse from getting deeper, slowly sink in pond, with flow quilt
In band inlet and outlet system, the problem of influencing effluent quality, occurs.

Specific implementation mode
Specific embodiment of the present utility model is described in detail with reference to preferred embodiment.
Attached drawing 1,2 is referred to, a kind of slag-draining device of flotation tank upper layer body refuse, including 1 He of dreg scraping buggy are present embodiments provided
Mud layer water conservancy diversion weir plate 7, the dreg scraping buggy side are equipped with the idler wheel 2 walked on the guide rail of pond, and the dreg scraping buggy other side is connected with branch
Frame 3, cantilever tip are connected with rotation axis 4, and scum board 5 is slidably connected in rotation axis, and the scum board surface is connected with steel wire
Rope 6, the steel wire rope other end take-up pulley (not shown) bonded with motor output shaft is connect.
Attached drawing 5 is referred to, the preferred embodiment of the present embodiment is the rectangular triangle in cross section of the mud layer water conservancy diversion weir plate,
Its level right angle side is 18.4 ° with bevel edge angle α.Original plate mud layer water conservancy diversion steel weir plate is replaced with into right angled triangle, then
The inclination weir plate that mud layer water conservancy diversion weir plate and flotation tank pool wall are 18.4 ° at angle, wedge angle is towards in air supporting water, the water of flotation tank
The position for not crossing mud layer water conservancy diversion weir plate half enables body refuse smoothly water conservancy diversion discharge.
The course of work
Start Slag Scraping Device and be adjusted to auto state, Slag Scraping Device proceed by scrape slag operation when, since limit switch is made
With motor puts down steel wire rope, makes scum board and the water surface in vertical state, is inserted into the water surface, slime layer is scraped to flotation tank end
Water conservancy diversion weir plate, by scum board rubber with angle of inclination weir plate it is seamless contact, body refuse is completely exhausted out flotation tank, so
Scum board touches limit switch afterwards, starts motor, by steel wire rope pull-up, scum board is made to be detached from the water surface with horizontality, waits for certain
After time, scum board equally keeps this state in return path, after returning to and initially scraping slag position, touches limit switch, fortune
Scum board is adjusted to plumbness, is inserted into the water surface by row motor.Cancel scum board gravity drop hammer, instead motor adds steel wire rope to draw
It drags, when scum board is travelled in scraping slag process to end, touching limit switch runs motor, drawn scum board by steel wire rope
It rises to horizontal position, is detached from the water surface, and keep hanging flashboard state so that scum board keeps horizontality in return path.
The above-mentioned detailed description carried out to a kind of slag-draining device of flotation tank upper layer body refuse with reference to embodiment, is illustrative
Without being restrictive, several embodiments can be enumerated according to limited range, therefore total not departing from the utility model
Change and modification under body design, should belong within the scope of protection of the utility model.
