the piston 15 is connected in a sliding way in the piston cylinder 34, the piston 15 is provided with a drug delivery pipe 36 in a penetrating way, the drug delivery pipe 36 is provided with a second one-way valve 30, and the second one-way valve 30 only allows the drug in the piston cylinder 34 to flow into the drug delivery pipe 36; the upper end of montant 37 is equipped with collecting vat 21, runs through on the montant 37 be equipped with two play medicine hole 39 that communicate with collecting vat 21, and wherein, play medicine hole 39 is close to the interior bottom setting of collecting vat 21, and goes out medicine hole 39 symmetric distribution on the circumference of montant 37, and medicine delivery pipe 36 is connected and communicates with collecting vat 21 with montant 37.
The fly ash washing liquid in the first clarifier 2 is conveyed into the conveying reaction cylinders 13 through the first conveying pipe 5, is respectively conveyed into the two conveying reaction cylinders 13 at the rear side through the third conveying pipe 14, and is finally conveyed into the second clarifier 3 through the second conveying pipe 6 for precipitation and clarification;
Meanwhile, the motor 12 is started, the motor 12 works to drive the transmission rod 10 and the cam 11 to rotate, the cam 11 rotates to drive the arc-shaped block 26 to move upwards, the reset spring 25 is compressed at the moment, when the cam 11 does not drive the arc-shaped block 26 to move upwards any more, the arc-shaped block 26 moves downwards to reset and offset the cam 11 under the action of the reset spring 25, so that the arc-shaped block 26 can move up and down, the arc-shaped block 26 moves up and down to drive the hexagonal prism 24, the vertical rod 37, the spiral mixing plate 38 and the second screen 38 to rotate, and fly ash washing liquid can be mixed and stirred;
Because the vertical rod 37 reciprocates up and down, when the vertical rod 37 moves downwards to drive the medicine conveying pipe 36 and the piston 15 to move downwards, na 2CO3 in the medicine cylinder 16 can be sucked into the piston cylinder 34 through the liquid inlet pipe 29 and the first one-way valve 35, when the vertical rod 37 drives the piston 15 to move upwards, the pressure in the piston cylinder 34 is increased, so that Na 2CO3 in the piston cylinder 34 and the medicine conveying pipe 36 can be conveyed into the collecting tank 21 and finally discharged into the flowing direction conveying reaction cylinder 13 through the medicine outlet hole 39 to be mixed with fly ash washing liquid, and the intermittent conveying is performed during medicine, so that excessive and waste of medicines caused by continuous conveying are avoided, and the problem of poor flocculation effect caused by too little medicine is avoided;
Similarly, feCl 3 and PAM can be added into the two conveying reaction cylinders 13 at the rear side;
Specific explanation for the mixing of Na 2CO3、FeCl3, PAM1 (drug for short):
When the transmission rod 10 is driven by the bevel gear 18 to realize rotation of the short rod 17 and the driving gear, and driven by the gear belt 19 to realize rotation of the transmission gear 20 and the sleeve 23, the hexagonal prism grooves 22 and the hexagonal prisms 24 are matched to realize rotation of the vertical rods 37 and the spiral mixing plates 38, and when the spiral mixing plates 38 rotate, medicines and fly ash water washing liquid flow along with the rotation of the spiral mixing plates 38 and the spiral mixing plates 38 move up and down, so that the medicines and the fly ash water washing liquid can be fully mixed;
The vertical rods 37 rotate to drive the second screen plate 28 to rotate and move up and down, so that when flowing medicine and fly ash water washing liquid pass through the second screen plate 28, the flowing resistance is increased, the flowing speed of the medicine and the fly ash water washing liquid is reduced, the pressure in the conveying reaction cylinder 13 is increased, the flowing speed of the medicine and the fly ash water washing liquid passing through the second screen plate 28 is increased, and the mixing effect of the medicine and the fly ash water washing liquid is further improved;
When the semicircular arc surface of the cam 11 is propped against the arc block 26, the first screen plate 27 and the second screen plate 28 prop against each other and rotate, and as the first screen plate 27 and the second screen plate 28 rotate, as shown in fig. 7, the opposite areas of the meshes on the first screen plate 27 and the second screen plate 28 are always changed, so that the flowing speed of the medicine and the fly ash water washing liquid can be further reduced, the stirring time of the medicine and the fly ash water washing liquid by the spiral mixing plate 38 which moves up and down and rotates can be increased, and the mixing effect can be improved;
Finally, the mixed medicine and the fly ash water washing liquid are conveyed into the second conveying reaction cylinder 13 through the third conveying pipe 14, and because the first screen plate 27 and the second screen plate 28 are arranged, the time for the medicine and the fly ash water washing liquid to pass through the second conveying reaction cylinder 13 is increased compared with the time for the medicine and the fly ash water washing liquid to pass through the first conveying reaction cylinder 13, and because the medicine and the fly ash water washing liquid can still be mixed with the previous medicine when passing through the second conveying reaction cylinder 13, the time for the medicine and the fly ash water washing liquid to pass through the second conveying reaction cylinder 13 is increased, the problem of insufficient mixing caused by short flow paths of FeCl 3 and the fly ash water washing liquid is solved, and similarly, the time for the medicine and the fly ash water washing liquid to pass through the second conveying reaction cylinder 13 is increased compared with the time for the medicine and the fly ash water washing liquid to pass through the third conveying reaction cylinder 13, so that the medicine and the fly ash water washing liquid can be fully mixed;
And finally conveying the fly ash water washing liquid mixed with the medicine into the second clarification tank 3 through a second conveying pipe 6 for flocculation precipitation.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
