Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment:
Embodiment 1
Fig. 1-4 is please referred to, a kind of sewage treatment lightweight floater scraping device is connect including precipitation tank 1 and with precipitation tank 1 Holding tank 6 is equipped with movable stand 2 on precipitation tank 1, and 2 bottom of movable stand is fixed with hanger 14, and hanger 14, which is equipped with, passes through liter The scraper mechanism of descending mechanism connection, the scraper mechanism includes bracket 26, and 26 bottom of bracket is fixedly installed with tooth plate 16, described to deposit It is vertically fixed the scraper plate 7 higher than 6 top edge of holding tank in storage tank 6, is equipped with draining web plate 8 in holding tank 6.
Precipitation tank 1 is for storing the sewage handled, and for sewage after the standing of one section of realization, density is lesser Light weight sundries are swum on liquid level, and the mobile of movable stand 2 can drive scraper mechanism mobile, and the bracket 26 in scraper mechanism is with movable tooth Plate 16 can be by the lightweight floater scraping on liquid level.
Specifically, scraper mechanism further includes the fixing axle 21 being fixed on bracket 26, in fixing axle 21 movable sleeve be equipped with The level board 19 of elevating mechanism transmission connection, is fixed with connecting spring 20 between level board 19 and bracket 26.
When bracket 26 is mobile, the light weight sundries on precipitation tank 1 are scraped by tooth plate 16, subsequently form aggregation, finally It drops on the draining web plate 8 in holding tank 6, and the scraper plate 7 being arranged can abut tooth plate 16, realization will be attached on tooth plate 16 Sundries strike off, due to the setting of connecting spring 20, tooth plate 16 and scraper plate 7 are able to achieve under 20 elastic reaction of connecting spring Sliding is abutted, guarantees that the light weight sundries on tooth plate 16 sufficiently scrape on draining web plate 8, avoids tooth plate 16 in next time to precipitation tank When 1 liquid level light weight sundries strike off, the light weight sundries being attached on tooth plate 16 are returned in precipitation tank 1.
Wherein, the specific moving process of movable stand 2 are as follows: movable stand 2 is equipped with movable motor 9, the output shaft of movable motor 9 It coaxially is fixed with walking gear 3, precipitation tank 1 and 6 side wall of holding tank are fixedly installed with the spur rack 5 engaged with walking gear 3, lead to The movable motor 9 for crossing setting carries out power drive to walking gear 3, and walking gear 3 passes through the spur rack 5 being engaged with and drives shifting Moving frame 2 is mobile, and then realizes that the driving to scraper mechanism is mobile.
In order to promote the mobile smoothness of scraper mechanism, guide groove 4, hanger 14 are offered on precipitation tank 1 and holding tank 6 Lower rotation formula is equipped with and is embedded the idler wheel 15 in guide groove 4, and when hanger 14 is mobile with movable stand 2, idler wheel 15 is along guide groove 4 It rolls, realizes to mechanism limition orientation is scraped, improve the stability that tooth plate 16 scrapes process, avoid that liquid level is biggish to be turned over Rolling, improves the scraping effect of light weight sundries.
Embodiment 2
On the basis of embodiment 1, since the amount of light weight sundries is different, the thickness accumulated on 1 liquid level of precipitation tank is also different, For this purpose, now the extended height of tooth plate 16 is adjusted in setting elevating mechanism, elevating mechanism includes being fixed on 14 bottom of hanger Dual-axle motor 12, two output shafts of dual-axle motor 12, which respectively drive, is connected with thread rotary orientation opposite threaded rod I11 and screw thread Equal thread bush is equipped with threaded sleeve 10 on bar II13, threaded rod I11 and threaded rod II13, between threaded sleeve 10 and level board 19 It is hinged with connecting rod 17.
By above-mentioned setting, dual-axle motor 12 can drive threaded rod I11 and threaded rod II13 to rotate simultaneously, threaded rod I11 Two threaded sleeves 10 connected thereon with threaded rod II13 driving realize that connecting rod 17 drives water towards or away from movement Plate 19 carries out the adjusting of height and position, i.e., the depth that tooth plate 16 extends to precipitation tank 1 is adjusted, ensure that tooth plate 16 is right The abundant scraping effect of light impurities in precipitation tank 1.
In addition, being fixed with casing 27 in 12 bottom of dual-axle motor, it is slidably fitted with lower end in casing 27 and level board 19 is solid Fixed traveller 18, is fixed with limit spring 22 between traveller 18 and casing 27, in the lifting process of level board 19,18 edge of traveller Casing 27 slide, limit spring 22 generate deformation and carry out bumper and absorbing shock, can effectively promote the stabilization of 16 lifting process of tooth plate.
Light weight sundries in holding tank 6 are cleared up for convenience, offer channel 25 on scraper plate 7,7 side wall of scraper plate and 6 side wall of holding tank is fixedly installed with symmetrically arranged stick II24 and stick I23,8 bottom of draining web plate and stick II24 respectively It is overlapped with stick I23.
By above-mentioned setting, draining web plate 8 can carry out draining effect to light weight sundries, and moisture passes through draining web plate 8 and passes through It crosses channel 25 to enter in the holding tank 6 of 8 lower part of draining web plate, realizes and be separated by solid-liquid separation, and draining web plate 8 rides over when in use On precipitation tank 1, it is supported by the stick II24 and stick I23 of setting, so that removing and installing for web plate 8 is simple rapid, It is convenient that subsequent processing is carried out to light weight sundries.
In conclusion the present invention realizes that tooth plate 16 will be on the water surface by the way that the scraper mechanism of setting is mobile on precipitation tank 1 Light weight sundries are struck off, and entire abrading process is simple and quick, and the elevating mechanism of setting can carry out the extended height of tooth plate 16 It adjusts, to adapt to the amount of light weight sundries, realizes the abundant scraping effect to light weight sundries, and the scraper plate 7 being arranged can be to tooth plate 16 The sundries of upper attachment is struck off, and is avoided enter into precipitation tank 1 and is caused repeated work, and it is efficient to effectively improve working efficiency, is added Fast sewage treatment process.
