Description
Technical field
The present invention relates to the technical field of the involved sewage disposal of municipal works and environmental engineering, a kind of slag-draining device for setting pot and Slagoff method thereof.
Background technology
In China's municipal works at present and environmental engineering, relate to the setting pot in sewage treatment project and must design slag-draining device to exclude the scum silica frost on surface.
Relatively common processing mode is: runs in one end of setting pot 1 cell body at liquid level and arranges skimming pipe 2, skimming pipe uses circular tubular structure, two ends are fixed, skimming pipe can rotate around tube hub line, skimming pipe one end is connected with scum pipe outside pond 3, have chute along pipe range direction, during operation, manually or automatically rotate skimming pipe, make the scum silica frost of liquid surface in pond flow in skimming pipe (seeing Fig. 1, Fig. 2, Fig. 3).
In practice, above-mentioned deslagging mode can there is problems in that
(1) it is to utilize current by liquid surface scum silica frost lead-in tube due to skimming pipe, its skimming effect is affected by the external environment bigger, if environment wind direction and water flow into skimming pipe direction and differ, when wind-force is bigger, in pond, liquid surface scum silica frost is gathered in one end by windage, it is impossible to flow into skimming pipe with current.
(2) the upper chute of skimming pipe utilization pipe is as scum silica frost entrance, owing to when it rotates, chute adjustment absolute altitude is limited, when therefore causing water level to have larger fluctuation when water yield change, it will affect its skimming effect.Having taken away substantial amounts of sewage in slag removal, the scum silica frost moisture content i.e. discharged is high simultaneously, and discharging slag needs external pressing device etc. to reprocess.
(3) skimming pipe is typically located at one end of setting pot, also has certain space, and scum silica frost is easily piled up in space in this place between skimming pipe and pool wall, and is not easy to remove.
Summary of the invention
It is an object of the present invention to provide a kind of slag-draining device for setting pot, the shortcoming that when skimming pipe both can have been overcome to be affected by wind-force, level fluctuation etc., effect is poor, can reduce again the moisture content discharging slag, remove follow-up pressing device etc. from.
In order to solve the problems referred to above, the technical scheme is that a kind of slag-draining device for setting pot, it is characterized in that in setting pot, arrange purlin vehicle type Slag Scraping Device, this vehicle type Slag Scraping Device bottom, purlin sets scum board, tailrace it is provided with in setting pot, it is provided with the slag bank of scraping of inclination between tailrace and setting pot, helical conveying squeezer is set in tailrace.Tailrace is arranged on the end of setting pot, and in tailrace, helical conveying squeezer is in tilted layout, and the port of export is slightly higher, and angle of inclination is 1 °～5 °, and tailrace arranges pulp water pipe by helical conveying squeezer low side.
Another object of the present invention is to provide a kind of Slagoff method for setting pot, the shortcoming that when skimming pipe both can have been overcome to be affected by wind-force, level fluctuation etc., effect is poor, can reduce again the moisture content discharging slag, remove follow-up pressing device etc. from.
In order to solve the problems referred to above, the technical scheme is that a kind of Slagoff method for setting pot, it is characterized in that in setting pot, arrange purlin vehicle type Slag Scraping Device, this vehicle type Slag Scraping Device bottom, purlin sets scum board, tailrace it is provided with in setting pot, be provided with inclination between tailrace and setting pot scrapes slag bank, helical conveying squeezer is set in tailrace, the outfan of helical conveying squeezer is connected with scum pipe, liquid level scum silica frost was scraped and was scraped slag bank by the scraper plate of purlin vehicle type Slag Scraping Device, pulp water flow back in setting pot, scum silica frost falls in the helical conveying squeezer of tailrace, after helical conveying squeezer squeezes, it is delivered to scum pipe discharge.
During use, liquid level scum silica frost was scraped and was scraped slag bank by the scraper plate of the purlin vehicle type Slag Scraping Device in the present invention, and pulp water flow back in pond, and scum silica frost is then scraped in the helical conveying squeezer of tailrace by scraper plate, and scum silica frost is delivered to scum pipe and discharges by helical conveying squeezer again.The present invention both can avoid wind-force, level fluctuation to affect deslagging effect, also a large amount of water will not be taken away in slag removal, i.e. can realize the function of squeezing simultaneously during using helical conveying squeezer conveying scum silica frost, avoid again scum silica frost to be deposited in tailrace, it is impossible to normal discharge.

Detailed description of the invention
With example, the present invention is further described below in conjunction with the accompanying drawings.
A kind of Slagoff method for setting pot of the present invention, it is characterized in that in setting pot 1, arrange purlin vehicle type Slag Scraping Device 4, this vehicle type Slag Scraping Device 4 bottom, purlin sets scum board 5, tailrace 6 it is provided with in setting pot, be provided with inclination between tailrace 6 and setting pot 1 scrapes slag bank 7, arranging helical conveying squeezer 8 in tailrace 6, the outfan of helical conveying squeezer 8 is connected with scum pipe 3.Tailrace 6 is arranged on the end of setting pot 1, and in tailrace 6, helical conveying squeezer 8 is in tilted layout, and the port of export is slightly higher, and angle of inclination is 1 °～5 °, and tailrace arranges pulp water pipe 9 by helical conveying squeezer 8 low side.Scraping slag bank 7 slightly higher by tailrace side, the inclination angle beta scraping slag bank 7 is 90 °～45.
The scum board of vehicle type Slag Scraping Device bottom, purlin scraped slag bank along with liquid level scum silica frost is scraped by the traveling of purlin car, and pulp water flow back in setting pot, and scum silica frost falls in the helical conveying squeezer of tailrace, is delivered to scum pipe and discharges after helical conveying squeezer squeezes.Scum board is flexible rubber goods, and along scraping during slag bank scrapes scum silica frost, scum board can bend to fit domatic.The bottom absolute altitude of scum board should be less than operating water level.The structure of described purlin vehicle type Slag Scraping Device is prior art, does not repeats them here.
During use, when purlin vehicle type Slag Scraping Device runs to tailrace direction, scraper plate scrapes setting pot surface scum, and its slagging-off effect is less by windage, and scum board itself has certain height simultaneously, its strong adaptability to water-level fluctuation.Scum board scum silica frost was scraped tailrace before scrape slag bank, scrape slag bank top mark height and be generally greater than operating water level 50mm～200mm, and scum board lowest point is slightly below operating water level, when scum silica frost is pushed to and to be scraped slag bank by scum board, moisture content in scum silica frost is flowed back in pond by action of gravity, scum silica frost the most finally drops in the helical conveying squeezer of tailrace, helical conveying squeezer uses and tilts to install, the port of export slightly to be raised, angle of inclination can be controlled in 1 °～5 °, when scum silica frost is carried to Way out by helical conveying squeezer, the pressing function of available helical conveying squeezer, reduce the moisture content of scum silica frost further, the moisture content of squeezing flows into tailrace, discharged by pipeline.
This arrangement, while ensureing deslagging effect, can avoid scum silica frost to be deposited in the drawback of channel, also avoids taking away major part sewage in tapping process, it is ensured that getting rid of scum silica frost has relatively low moisture content simultaneously.
The present invention has simple arrangement form, has bigger advantage in design, construction, operational management, can be used for the surface deslagging of newly-built setting pot in sewage disposal it can also be used to the transformation of deslagging facility in built setting pot.
