Description

Technical Field

[0001] This application relates to filtration technology for water used in wire rod production, and more particularly to a cooling water slag removal device. Background Technology

[0002] In the production of wire rod, hot-rolled steel needs to be rinsed with water to remove the oxide scale generated during the rolling process. This is typically done by high-pressure spraying of cooling water onto the surface of the hot-rolled steel, causing the oxide scale to crack and fall off. The rinsing cooling water then needs to be filtered to remove slag before being recycled.

[0003] Oxide scale fragments and particles in existing cooling water are usually filtered out by a filter screen in a filter box. During long-term continuous production, the amount of oxide scale accumulated on the surface of rolled steel is large, which can easily clog the filter screen in the filter box, requiring frequent shutdowns for manual cleaning or replacement of the filter screen. Utility Model Content

[0004] This application provides a cooling water slag removal device to solve the problem that existing rinsing cooling water is prone to clogging the filter screen during the slag removal process and requires frequent cleaning.

[0005] This application provides a cooling water slag removal device, including a treatment box. The bottom of the treatment box is vertically fixed with a partition that divides it into a water tank and a slag tank. A conveyor belt is installed at an incline on the upper end of the water tank. The end of the conveyor belt passes upward over the partition and has a downward bend that extends into the slag tank. The conveyor belt is driven by a drive mechanism that rotates the drive rollers at both ends to transport and circulate the water along the incline. Multiple magnetic rollers are provided in the conveyor belt located above the water tank. The top wall of the treatment box consists of two inclined plates that slope downward towards the center, with an opening between the two inclined plates. A slag cleaning door is provided on the side end of the slag tank.

[0006] Optionally, side baffles are provided on both sides above the conveyor belt along the conveying direction.

[0007] Optionally, an overflow plate is fixed inside the water tank at the downward-sloping end of the conveyor belt. The overflow plate separates the water tank into a sedimentation zone and a clear water zone. The overflow plate is provided with an overflow port, and the water pump's pumping pipe is inserted into the clear water zone.

[0008] Optionally, the processing box is equipped with a fan at the upper end of the side wall of the slag trough for cooling the cooling water flowing into the box.

[0009] Optionally, the processing box has air vents on the side wall opposite to the fan.

[0010] The cooling water descaling device provided in this application uses sprayed cooling water to wash away the oxide scale generated during steel rolling. The oxide scale falls into a treatment tank, where it is adsorbed onto a conveyor belt by a magnetic roller and separated from the cooling water. The cooling water flows into a water tank within the treatment tank for reuse, while the oxide scale adsorbed on the conveyor belt is transported to a slag trough. The conveyor belt and magnetic roller effectively remove oxide scale fragments and particles from the cooling water, facilitating cooling water recycling. Furthermore, there is no risk of filter clogging, resulting in a long service life and low maintenance frequency. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0015] like Figures 1-3As shown, one embodiment of this application provides a cooling water slag removal device, including a treatment tank 1. The bottom of the treatment tank 1 is vertically fixed with a partition 3 that divides it into a water tank and a slag tank. A conveyor belt 2 is installed at an incline on the upper end of the water tank. The end of the conveyor belt 2 passes upward over the partition 3 and has a downward bend 4 that extends into the slag tank. The conveyor belt 2 is driven by a drive mechanism 6 to rotate the drive rollers at both ends to transport and circulate the water along the incline. Multiple magnetic rollers 5 are provided in the conveyor belt 2 located above the water tank. The top wall of the treatment tank 1 consists of two inclined plates 8 that slope downward towards the center. There is an opening between the two inclined plates 8. A slag cleaning door 9 is provided on the side end of the slag tank.

[0016] In operation, the treatment tank 1 is positioned below the spraying equipment to receive cooling water. After rinsing off the oxide scale, the cooling water falls onto the inclined plate 8 of the treatment tank 1 and flows into the treatment tank 1 from the opening along the inclined plate 8. Cooling water and broken oxide scale enter through the opening and fall onto the conveyor belt 2. The cooling water flows downwards along the inclined surface of the conveyor belt 2 into the water tank of the treatment tank 1, while the broken oxide scale is adsorbed onto the top surface of the conveyor belt 2 by the magnetic roller 5. The drive mechanism 6 drives the conveyor belt 2 to circulate upwards along the inclined surface, conveying the oxide scale fragments and particles adsorbed on the top surface of the conveyor belt 2 into the slag trough. When the oxide scale fragments and particles move to the bend 4, they lose the magnetic attraction of the magnetic roller 5 and fall from the inclined surface of the bend 4 into the slag trough. The water in the water tank after removing the oxide scale is recycled, and the oxide scale concentrated in the slag trough is periodically cleaned through the slag cleaning gate 9.

[0017] In this embodiment, the cooling water used for spraying falls into the treatment tank 1 after rinsing the oxide scale generated during steel rolling. Inside the treatment tank 1, the oxide scale is adsorbed onto the conveyor belt 2 by the magnetic roller 5, separating it from the cooling water. The cooling water flows into a water tank within the treatment tank 1 for reuse, while the oxide scale adsorbed on the conveyor belt 2 is transported to the slag trough via the conveyor belt 2. The conveyor belt 2 and magnetic roller 5 effectively remove oxide scale fragments and particles from the cooling water, facilitating cooling water recycling. Furthermore, there is no risk of filter clogging, resulting in a long service life and low maintenance frequency.

[0018] In one possible implementation, side baffles 7 are respectively provided on both sides of the conveyor belt 2 along the conveying direction.

[0019] The side baffle 7 can shield both sides of the conveyor belt 2 in the conveying direction, reducing the risk of side leakage of cooling water and oxide scale fragments.

[0020] In one possible implementation, an overflow plate 10 is fixed inside the water tank at one end of the conveyor belt 2 that is inclined downwards. The overflow plate 10 divides the water tank into a sedimentation zone and a clear water zone. The overflow plate 10 is provided with an overflow port 11, and the water pump's pumping pipe 12 is inserted into the clear water zone.

[0021] After settling in the sedimentation zone, the cooling water entering the water tank flows into the clear water zone through the overflow port 11. The water pump's suction pipe 12 is inserted into the clear water zone to draw cooling water for recycling. The sedimentation zone further filters out impurities from the cooling water.

[0022] In one possible implementation, the processing box 1 is equipped with a fan 13 at the upper end of the side wall of the slag trough for cooling the cooling water flowing into the box.

[0023] The blower 13 can blow air or exhaust air into the treatment box 1 to cool the cooling water in the treatment box 1, keeping the cooling water in the range of 30-50℃. When the cooling water comes into contact with the hot-rolled steel, the stress generated by the temperature difference can promote the cracking of the oxide scale, resulting in a better washing effect on the oxide scale.

[0024] In one possible implementation, the processing box 1 has a vent 14 on the side wall opposite to the fan 13.

[0025] The air vent 14 can provide a smooth air inlet or outlet for the treatment box 1, and form an air duct that runs through the treatment box 1 between the air vent 14 and the fan 13 to discharge hot air.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
