One dust mud environmental protection clearing and retrieving device of the present invention, is provided with liquid level controller in its cistern.
One dust mud environmental protection clearing and retrieving device of the present invention, is provided with drainage screen in its cistern.
Compared with prior art, the invention has the beneficial effects as follows:
One dust mud environmental protection clearing and retrieving device the most of the present invention, twice spraying-rinsing of conveyer belt to upstream belt feeder by first jet and second nozzle, under the effect of booster water pump, recycling sewage and be carried out, the upstream belt feeder after cleaning is effectively improved conveying capacity.
One dust mud environmental protection clearing and retrieving device the most of the present invention, under the effect of air pump, the moisture content of residual on the conveyer belt of air knife drying upstream belt feeder, prevent from remaining moisture content again by material sticks on the conveyor belt.
One dust mud environmental protection clearing and retrieving device the most of the present invention, drainage screen it is provided with in cistern, effectively mud can be separated with sewage, the sewage on upper strata is extracted out the conveyer belt cleaning upstream belt feeder by booster water pump, the mud of lower floor is extracted out by sludge pump and is transported on the conveyer belt of downstream belt feeder, and the liquid level controller arranged in cistern, can be accurately controlled startup and the stopping of sludge pump.

Detailed description of the invention
nullSee Fig. 1,The present invention relates to a kind of dust mud environmental protection clearing and retrieving device,For clearing up and reclaim the mud of the conveyor belt surface of belt feeder,Dust mud environmental protection clearing and retrieving device includes first jet 2、Second nozzle 3、Air knife 4、Return water tank 6、Air pump 7、Cistern 8、Sludge pump 10 and liquid level controller 11,Described first jet 2、Second nozzle 3 and air knife 4 are sequentially located at below the conveyer belt of upstream belt feeder,Described return water tank 6 is positioned at first jet 2 and the lower section of second nozzle 3,Return water tank 6 is for reclaiming mud and the sewage that first jet 2 and second nozzle 3 are cleared up from the conveyer belt of upstream belt feeder,Described cistern 8 is positioned at the lower section of return water tank 6,First jet 2 is connected with the top of cistern 8,First jet 2 is provided with booster water pump 9 on the connection pipeline of cistern 8,Booster water pump 9 is for spraying the sewage force feed in cistern 8 to first jet 2,The conveyer belt of upstream belt feeder is carried out,Described second nozzle 3 is connected with running water inlet,Second nozzle 3 is provided with electromagnetic valve 5 on the connection pipeline of running water inlet,Electromagnetic valve 5 is for controlling the inflow of tap water,Described air knife 4 is connected with air pump 7,Under the effect of air pump 7,The conveyer belt blowing of air knife 4 upstream belt feeder,Dry up the moisture content of residual on conveyer belt.
Described air pump 7 is vortex air pump.
Described cistern 8 is in funnel shaped, the outlet of return water tank 6 is connected with the import of cistern 8 bottom, sewage in return water tank 6 flows into cistern 8, in cistern 8, middle part is provided with drainage screen 13, mud is separated by drainage screen 13 with sewage, is additionally provided with liquid level controller 11 in cistern 8, and the sludge outlet bottom cistern 8 is passed through on the conveyer belt of downstream belt feeder by sludge pump 10, by observing liquid level controller 11, control startup and the stopping of sludge pump 10 easily.
Operation principle:
The conveyer belt of upstream belt feeder rotates clockwise, and is transported on the conveyer belt of downstream belt feeder by the material on conveyer belt, after using the time longer, the conveyer belt of upstream belt feeder can be stained with mud, affect conveying capacity.
One dust mud environmental protection clearing and retrieving device of the present invention, upstream belt feeder and downstream belt feeder are in operation process, electromagnetic valve 5 is energized and is opened by tap water, tap water is sprayed onto on the conveyer belt of upstream belt feeder by second nozzle 3, sewage after cleaning falls into return water tank 6, and the sewage in return water tank 6 flows into the bottom of cistern 8 under its action of gravity, under the effect of booster water pump 9, sewage in cistern 8 cleans the conveyer belt of upstream belt feeder from first jet 2 ejection, thus forms circulation.
Through first jet 2 and the cleaning of second nozzle 3, under the effect of air pump 7, the conveyer belt of upstream belt feeder is dried up by air knife 4, prevents subsequent delivery material from again sticking on the conveyer belt of upstream belt feeder.
Owing to the outlet of return water tank 6 is connected with the lower inlet of cistern 8, and it is provided with drainage screen 13 in cistern 8, therefore in cistern 8, drainage screen 13 lower floor is mainly mud, upper strata is mainly sewage, when the liquid level of upper strata sewage arrives sludge pump priming level 11.1, sludge pump 10 is started working, the mud of cistern 8 lower floor is extracted on the conveyer belt of downstream belt feeder, therefore the residual mud on the conveyer belt of upstream belt feeder has been reclaimed, when the liquid level of drainage screen 13 upper strata sewage arrives sludge pump stopping water level 11.2, sludge pump 10 quits work, cistern 8 restarts water-retention.
