Principle of operation
Adding silicon carbide into the sand blasting box 13, then moving the equipment to a position where rust removal is needed, and starting to work;
Firstly, the clamping sleeve 20 is opened, so that the clamping sleeve 20 rotates around the clamping shaft 49, at the moment, the clamping coil spring 48 starts to store force, after a certain opening is opened, the clamping sleeve 20 is sleeved on a guardrail needing rust removal, at the moment, the clamping sleeve 20 is loosened, the clamping sleeve 20 clamps and wraps the bridge guardrail because the clamping coil spring 48 loses pressure, then the recovery seat 17 is moved to the position, two sliding clamping blocks 38 are clamped on one side of the recovery outer baffle 18 on the surface of the guardrail to prevent the recovery seat 17 from falling, the recovery seat 17 is moved so that the recovery outer baffle 18 originally clamped on the surface of the guardrail can move the recovery inner baffle 19 on one side of the recovery outer baffle 18 into the clamping sleeve 20 to form sealing, the recovery outer baffle 18 on the other side is also clamped on the surface of the guardrail after being moved, so that the recovery inner baffle 19 on the side is also moved into the clamping sleeve 20 to form sealing, and the two recovery inner baffle rings 19 can continuously apply force inwards under the action of the recovery spring 42 on the rear side to prevent the recovery outer baffle 18 from popping up sealing capacity is better;
Then starting a motor, and enabling the sand conveying motor 43 to operate firstly to spray the carborundum in the sand spraying box 13 through the sand spraying pipe 15, enabling the carborundum to enter the upper end of the sand spraying pipe 15 and then be sprayed out by the sand spraying motor 45 in a pressurizing mode so as to rust-remove the surface of the guardrail, wherein in the rust-removing process, the sand spraying rotating sleeve 21 can be slid along the sand spraying slideway 52 in the sand spraying rotating sleeve 21, and therefore the sand spraying head 46 can remove rust of the bridge railing at more angles;
In the rust removal process, the generated large wind force enters the recovery seat 17 through the recovery ports 40 below the two recovery inner baffle rings 19 which are arranged at two sides in the need of sealing at the moment, the wind force enters the recovery seat 17 and enters the screening box 12 through the telescopic recovery pipe 41 and the recovery pipe 37, dust, waste gas and sprayed silicon carbide generated by sand blasting rust removal also fall on the surface of the sand filter screen 27 under the action of gravity after entering the screening box 12 through the recovery pipe 16 along with the wind force, and small particulate matters are filtered by the sand filter screen 27 and fall into the dust box 11 below through the dust collecting cone 24, and the dust is not easy to return in the original way after blowing into the dust box 11 due to the inclined design of the dust collecting cone 24;
While the sand conveying motor 43 is operated, the centrifugal motor 50 is operated to drive the upper centrifugal driving wheel 51 to rotate, the centrifugal driving wheel 51 rotates to enable the driven gear 36 meshed with the centrifugal driving wheel to rotate and drive the lower transmission toothed ring 34 to rotate through the connecting sleeve 35, the transmission toothed ring 34 rotates to enable the lower centrifugal toothed ring 33 meshed with the centrifugal driving wheel 33 to also rotate, the centrifugal toothed ring 33 rotates to enable the centrifugal device 30 to rotate, at the moment, because wind blows into the screening box 12 and the beating shaft 29 can rotate, the beating fan 28 and the centrifugal device 30 are reversely rotated by the wind blowing, so that larger-particle silicon carbide which is not filtered by the sand filtering net 27 can be simply beaten, so that the silicon carbide can obtain a transverse force to gradually rise along the inclined plane of the centrifugal channel 31, and can be discharged along with the continuous rotation of the centrifugal device 30 after rising to the highest place, the thrown silicon carbide can fall down into the return pipe 14 under the action of the return channels 26 at two sides, and return into the sand box 13 through the return pipe 14, and the purpose of recycling is achieved;
after the rust removal maintenance is completed, the apparatus may be closed, and the cleaning door 25 may be opened to recover the waste gas and the like accumulated in the dust box 11.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present invention or directly or indirectly applied to other related technical fields are included in the scope of the invention.
