Description
Technical field
The present invention relates to the pretreating process section of sewage disposal, specifically a kind of slag-scraper of aerated grit chamber.
Background technology
Aerated grit chamber is pretreatment unit important in sewage disposal, is mainly responsible for the task of desanding and descum.But but lack suitable slag-scraper for a long time always.
Existing slag-scraper is generally arranged on the car of purlin.When purlin car moves to water inlet end, sensor such as limit switch detects purlin car, and purlin car stops and putting down scraper plate by motor.Rear spar car move to water side, namely scraper plate scrapes slag from water inlet end to water side.When purlin car moves to water side, corresponding sensor detects purlin car equally, and purlin car stops and rising scraper plate by motor.Whole process service routine controls, and depends on sensor device.
But such device is in moist, dirty environment, fault rate is higher.And once lose efficacy, gently then uncontrollable motor lifting scum board is with descum, heavy then may cause purlin car derailing, cable bad, even hurt staff, causes the accident.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of slag-scraper of aerated grit chamber, not relying on purlin car and running, also controlling without the need to sensor device, can stability and high efficiency ground descum.
Technical scheme of the present invention is: a kind of slag-scraper of aerated grit chamber, comprises scraper plate, scrapes slag arm, walking gear, driving shaft, driven shaft, fixing chain, driving shaft chute, driven shaft chute.Wherein, scraper plate, scrapes slag arm, walking gear, driving shaft, the moving-member of driven shaft composition slag-scraper; And fixing chain, driving shaft chute, the fixed part of driven shaft chute composition slag-scraper.Scraper plate is arranged on to be scraped on slag arm, and can adjust setting height(from bottom) and angle as required.Scrape slag arm to be connected with driving shaft and driven shaft.Driving shaft and driven the tip of the axis are separately installed with bearing, and this bearing can make driving shaft and driven shaft move in driving shaft chute and driven shaft chute respectively.Walking gear is arranged on driving shaft, moves on fixing chain by rotating with driving shaft.
Operation principle of the present invention is: fixing chain, driving shaft chute, driven shaft chute, be arranged on respectively and scrape on slag overlying regions sidewall, determines the track of moving-member motion with this.The operation of walking gear on fixing chain achieves slag scraping mechanism and is scraping the reciprocating motion in slag region and driving shaft in the upper and lower lifting of fixing chain.The change of relative position between driving shaft and driven shaft, achieves scraper plate and lifts to get back to water inlet end or insert the water surface and scrape the action of slag to water side.
Advantage of the present invention is: the slag-scraper that the invention provides a kind of aerated grit chamber, achieve do not rely on purlin car run and motor lifting scraper plate scrape slag continuously, simultaneously owing to controlling without the need to sensor device, operation is simple, has the advantage of stability and high efficiency.

Detailed description of the invention
Below provide embodiments of the invention, and attached diagram is with aid illustration.
As shown in Figure 1, a kind of slag-scraper of aerated grit chamber, comprises scraper plate 1, scrapes slag arm 2, walking gear 3, driving shaft 4, driven shaft 5, fixing chain 6, driving shaft chute 7, driven shaft chute 8.Wherein, scraper plate 1, scrapes slag arm 2, walking gear 3, driving shaft 4, and driven shaft 5 forms the moving-member of slag-scraper; And fixing chain 6, driving shaft chute 7, driven shaft chute 8 forms the fixed part of slag-scraper.Specifically, scraper plate 1 is arranged on to be scraped on slag arm 2, and can adjust setting height(from bottom) and angle as required.Scrape slag arm 2 to be connected with driving shaft 4 and driven shaft 5.Wherein driving shaft 4 moves in driving shaft chute 7, and driven shaft 5 moves in driven shaft chute 8.Walking gear 3 is arranged on driving shaft 4, moves on fixing chain 6 by rotating with driving shaft.
As shown in Figure 2, moving-member in slag-scraper of the present invention, comprises scraper plate 1, scrapes slag arm 2, walking gear 3, driving shaft 4, driven shaft 5.Wherein driving shaft 4 is identical with driven shaft 5 width, and is provided with measure-alike bearing 9 at end.Bearing 9 can make driving shaft 4 and driven shaft 5 move in driving shaft chute 7 and driven shaft chute 8 respectively.
As shown in Figure 3, bearing 9 is roller bearings, utilizes roller 10 that the rotation of Internal and external cycle can be made independent mutually.Such as driving shaft 4, in its process driving walking gear 3 to move, can move with the direction of motion of moving-member in the outer ring of bearing 9 in driving shaft chute 7.
As shown in Figure 4, fixed part in slag-scraper of the present invention, comprises fixing chain 6, driving shaft chute 7, driven shaft chute 8.Fig. 4 is the top view schematic diagram intercepting a representative part in fixed part.Fixing chain 6, driving shaft chute 7, driven shaft chute 8 is arranged on respectively to be scraped on slag overlying regions sidewall, and it is corresponding with moving-member in slag-scraper that it installs width.
As shown in Figure 5, in slag-scraper of the present invention, fixed part is arranged on the assigned address scraped on slag overlying regions sidewall.
When moving-member is shown in Fig. 5 a during position, scraper plate 1 stretches into below liquid level.Along with the motion of walking gear 3 on fixing chain, the scum silica frost swum on liquid level strikes off from water inlet end to water side by scraper plate 1.Scrape the state of slag arm 2 by the driving shaft 4 in chute and driven shaft 5 co-controlling.
When moving-member moves to position shown in Fig. 5 b, scum silica frost is scraped near slag bucket along slope by scraper plate 1.Along with the continuation campaign of walking gear 3, scum silica frost will be scraped in slag bucket, complete and scrape slag.
When moving-member moves to position shown in Fig. 5 c, walking gear 3 and driving shaft 4 have been moved to the top of fixing chain 6.Due to the invariant position of driven shaft chute 8, so time driving shaft 4 and driven shaft 5 between relative position change, scrape slag arm 2 and be lifted, scraper plate 1 is corresponding to the water surface.
When moving-member moves to position shown in Fig. 5 d, scraper plate 1 with scrape slag arm 2 and move to water inlet end under away from the state of the water surface.Until walking gear 3 and driving shaft 4 move to the below of fixing chain 6 again, scrape slag arm 2 and drive scraper plate 1 to extend into below the water surface, start another time and scrape slag action.
