Description

Automatic rotating device for removing sludge from grate

The utility model relates to a kind of full-automatic revolution grizzly bar sewage disposal apparatus, is particularly suitable for medium and small power station, and large-size thermal power plant, chemical plant and city tap-water factory, Wastewater Treatment Plant remove dirt use in the water.

Present all kinds of water producer fixedly installs row's trashrack bar often before watering equipment; to stop dirt to enter watering equipment; avoid causing multiple accidents such as shutdown; but when dirt gathers some on grizzly bar; can only lean on manually the dirt on the grizzly bar is harrowed; or on grizzly bar, move the rake dirt with the dirty machine of electronic rake; this fixedly blowdown grizzly bar is removed contamination: adopt and manually exist the dirty difficulty of rake and unsafe shortcoming; adopt electronic rake dirt to exist the dirt that is difficult to remove in the grizzly bar gap again; caused streamflow to reduce significantly; force plant shut down to be removed contamination, thereby influence the shortcoming of ordinary production.

At the shortcoming of above-mentioned existing sewage disposal apparatus, the purpose of this utility model is to provide a kind of and does not need manually, removes dirt thoroughly, reliably, and the full-automatic revolution grizzly bar sewage disposal apparatus that need not shut down.

The purpose of this utility model is achieved in that the utility model of being made up of frame, motor, electric control box and reducer, its grizzly bar both sides have chain, this chain by its pulley bearing on the guide rail that is fixed as one with frame, and the sprocket on this chain and the power transmission shaft matches, grizzly bar is made of the grid sheet that evenly is socketed on the chain shaft, grid sheet one end has holder thing hook, and the other end and middle part have the hole that matches with chain shaft, and the grid sheet evenly is socketed in and forms the grizzly bar grid on the chain shaft.

Also has the cam of removing contamination that matches with the grizzly bar gap on the power transmission shaft.

Be provided with the waterpower nozzle of removing contamination above the arc-shaped guide rail of power transmission shaft between the corresponding frame being lower than, be provided with the rotation brush of removing contamination below this arc-shaped guide rail between the corresponding frame.

Also be provided with the water-head detecting head on the frame before and after the grizzly bar, this detecting head links to each other with electric control box by lead.

The utility model has the automaticity height owing to adopted chain type revolution grizzly bar to replace fixedly grizzly bar, removes contamination conveniently, thoroughly, does not need manpower, need not shut down, strong, safe in utilization, the reliable advantage of pollution discharge capability.

Below in conjunction with accompanying drawing the utility model and embodiment are elaborated:

Fig. 1 is the utility model structural representation;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the partial structurtes figure of chain type revolution grizzly bar 3;

Fig. 4 is the D-D sectional view of Fig. 3;

Fig. 5 is the structure chart of grid sheet 14;

Referring to Fig. 1, Fig. 2: the utility model by frame 1, guide rail 2, chain type revolution grizzly bar 3, power transmission shaft 4, waterpower remove contamination nozzle 5, rotation remove contamination brush 6, dirt groove 7, unload dirty conveyor 8, water-head detecting head 9, motor 10, reducer 11 and electric control box 12 and form.Frame 1 below is equipped with rotating cylinder 13, the top is equipped with power transmission shaft 4, power transmission shaft 4 links to each other with the output of reducer 11, reducer 11, motor 10 all is fixedly mounted on the frame 1, chain type revolution grizzly bar 3 is enclosed within on rotating cylinder 13 and the power transmission shaft 4, and having on the frame 1 between rotating cylinder 13 and the power transmission shaft 4 with the horizontal direction angle is 60-90 ° guide rail 2, the chain roller 14 of chain type revolution grizzly bar 3 both sides is by 2 supportings of two guide rails, sprocket on chain and the power transmission shaft 4 matches, also has the cam of removing contamination that matches with the grizzly bar space between the sprocket, grizzly bar is made up of (referring to Fig. 3 a plurality of grid sheets 15 that are enclosed within on the chain shaft 16, Fig. 4), and form uniform grid, so that water can pass through smoothly, grid sheet 15(is referring to Fig. 5) end has holder thing hook, the other end and middle part have the hole that matches with chain shaft 16, on the frame 1 of power transmission shaft below 4, also has one section arc-shaped guide rail, be equipped with between the frame 1 of this guide rail top by the waterpower of the solenoid control nozzle 5 of removing contamination, also be equipped with between the frame 1 of below and rotate the brush 6 of removing contamination, at the cam of removing contamination, waterpower remove contamination nozzle 5 and the rotation remove contamination the brush 6 belows dirt groove 7 also is installed, dirt groove 7 bottoms have unloads dirty belt 8, on the frame 1 of chain type revolution grizzly bar 3 front and back, water-head detecting head 9 also is installed, this detecting head joins by lead and electric control box 12, and electric control box can be controlled motor 10 and electromagnetic valve action.The rotation brush 6 of removing contamination provides power by chain or the belt that joins with turning cylinder 4.

When the dirt collection on the chain type revolution grizzly bar arrives to a certain degree, cause the certain water-head in grizzly bar front and back, at this moment by water-head detecting head 9 with signals collecting and deliver to electric control box 12, send signal by electronic control box 12 and make motor 10 rotations, this moment, power transmission shaft 4 rotations and drive grizzly bar were done gyration, because grizzly bar is done gyration, hooking dirt by the holder thing hook on the grizzly bar moves upward, when moving to power transmission shaft 4 positions, dirt is under the gravity and the cam of removing contamination, fall into dirt groove 7, the dirt that does not leave simultaneously grizzly bar is removed contamination and is also fallen into dirt groove 7 under the effect of brush 6 in remove contamination nozzle 5 and rotation of waterpower, transports by unloading dirty belt 8 at last, after dirt removal arrives to a certain degree, water-head before and after the grizzly bar is dwindled, and the signal of electric control box generation at this moment makes motor 10 and electromagnetic valve outage, and this device quits work.

This device also can be provided with manual control mechanism, and the chain strip adoption national standard metric system meropodium of grizzly bar both sides rotates the brush of removing contamination and makes for sheet rubber or other soft materials apart from conduction chain.
