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 important pretreatment unit in sewage disposal, is mainly responsible for appointing for desanding and descum
Business.But but lack suitable slag-scraper always for a long time.
Existing slag-scraper is typically mounted on the car of purlin.When purlin car moves to water inlet end, sensor such as limit switch
Purlin car is detected, purlin car stops and puts down scraper plate by motor.Rear spar car to water outlet end motion, scraper plate is from water inlet end to going out
Water end (W.E.) scrapes slag.When purlin car moves to water side, corresponding sensor equally detects purlin car, and purlin car stops and by motor liter
Play scraper plate.Whole process uses programme-control, and depends on sensor device.
But such device, in moist, dirty environment, fault rate is higher.And once fail, light then uncontrollable electricity
Machine lifts scum board with descum, heavy then be likely to result in the derailing of purlin car, cable bad, even hurt staff, causes
Accident.
The content of the invention
In order to overcome drawbacks described above, the present invention to provide a kind of slag-scraper of aerated grit chamber, purlin car operation is not relied on,
Without sensor device control, being capable of stability and high efficiency ground descum.
The technical scheme is that：A kind of slag-scraper of aerated grit chamber, including scraper plate, scrape slag arm, walking gear,
Driving shaft, driven shaft, fixed chain, driving shaft chute, driven shaft chute.Wherein, scraper plate, scrapes slag arm, walking gear, active
Axle, driven shaft constitutes the moving parts of slag-scraper；And fixed chain, driving shaft chute, driven shaft chute composition slag-scraper
Fixed component.Scraper plate is arranged on and scrapes on slag arm, and can as needed adjust setting height(from bottom) and angle.Scrape slag arm and driving shaft and
Driven shaft is connected.Driving shaft is separately installed with bearing with driven the tip of the axis, and this bearing can make driving shaft and driven shaft exist respectively
Motion in driving shaft chute and driven shaft chute.Walking gear is arranged on driving shaft, is rotated in fixed chain by with driving shaft
Moved on bar.
Operation principle of the invention is：Fixed chain, driving shaft chute, driven shaft chute, are separately mounted to scrape slag region
On upper side wall, the track of moving parts motion is determined with this.Operation of the walking gear on fixed chain is realized scrapes slag
The reciprocating motion in slag region and driving shaft are being scraped in the upper and lower lifting of fixed chain by mechanism.It is relative between driving shaft and driven shaft
The change of position, realizes scraper plate and lifts and return to water inlet end or the insertion water surface scrapes the action of slag to water side.
It is an advantage of the invention that：The present invention provides a kind of slag-scraper of aerated grit chamber, realizes and does not rely on purlin car
Operation and the continuous of motor lifting scraper plate scrape slag, simultaneously because without sensor device control, operation is simple, with stabilization
Efficient advantage.

Specific embodiment
An embodiments of the invention presented below, and attached diagram is aiding in illustrating.
As shown in figure 1, a kind of slag-scraper of aerated grit chamber, including scraper plate 1, scrape slag arm 2, walking gear 3, driving shaft
4, driven shaft 5, fixed chain 6, driving shaft chute 7, driven shaft chute 8.Wherein, scraper plate 1, scrapes slag arm 2, walking gear 3, active
Axle 4, driven shaft 5 constitutes the moving parts of slag-scraper；And chain 6 is fixed, driving shaft chute 7, the composition of driven shaft chute 8 scrapes slag
The fixed component of device.Specifically, scraper plate 1 is arranged on and scrapes on slag arm 2, and can as needed adjust setting height(from bottom) and angle.Scrape
Slag arm 2 is connected with driving shaft 4 and driven shaft 5.The wherein motion in driving shaft chute 7 of driving shaft 4, and driven shaft 5 is in driven shaft
Motion in chute 8.Walking gear 3 is arranged on driving shaft 4, is moved on fixed chain 6 by being rotated with driving shaft.
As shown in Fig. 2 moving parts in slag-scraper of the present invention, including scraper plate 1, slag arm 2 is scraped, walking gear 3 is main
Moving axis 4, driven shaft 5.Wherein driving shaft 4 is identical with the width of driven shaft 5, and is provided with size identical bearing 9 in end.Bearing
9 can make the motion in driving shaft chute 7 and driven shaft chute 8 respectively of driving shaft 4 and driven shaft 5.
As shown in figure 3, bearing 9 is roller bearing, the rotation of Internal and external cycle can be made independent mutually using roller 10.For example for
For driving shaft 4, during it drives walking gear 3 to move, the outer ring of bearing 9 can be in driving shaft chute 7 with move portion
The direction of motion motion of part.
As shown in figure 4, fixed component in slag-scraper of the present invention, including chain 6 is fixed, driving shaft chute 7 is driven
Axle chute 8.Fig. 4 is the top view schematic diagram of the representative part of interception one in fixed component.Fixed chain 6, driving shaft chute 7,
Driven shaft chute 8 is separately mounted to scrape on the wall of slag overlying regions side, and it is corresponding with moving parts in slag-scraper that it installs width.
As shown in figure 5, fixed component is specified on the wall of slag overlying regions side installed in scraping in slag-scraper of the present invention
Position.
When moving parts is in position shown in Fig. 5 a, scraper plate 1 is stretched into below liquid level.As walking gear 3 is in fixed chain
On motion, the scum silica frost that scraper plate 1 will be swum on liquid level strikes off from water inlet end to water side.The state of slag arm 2 is scraped by chute
Driving shaft 4 and the co- controlling of driven shaft 5.
When moving parts moves to position shown in Fig. 5 b, scraper plate 1 is scraped to slag bucket scum silica frost along slope.With row
The continuation campaign of gear 3 is walked, scum silica frost will be scraped in slag bucket, slag is scraped in completion.
When moving parts moves to position shown in Fig. 5 c, walking gear 3 and driving shaft 4 have been moved to fixed chain 6
Top.Because the position of driven shaft chute 8 is constant, so when relative position between driving shaft 4 and driven shaft 5 change,
Scrape slag arm 2 to be lifted, scraper plate 1 is corresponding away from the water surface.
When moving parts moves to position shown in Fig. 5 d, scraper plate 1 with scrape slag arm 2 in the state of away from the water surface to water inlet
End movement.Until walking gear 3 and driving shaft 4 move to the lower section of fixed 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.
