Description

Technical Field

[0001] This invention belongs to the field of metal surface treatment technology, and in particular relates to a spiral rust removal device for wire rod. Background Technology

[0002] Wire rod, also known as coiled wire, typically refers to small-diameter round steel coils. Rust on the surface of wire rod affects its usability, therefore, rust removal treatment is necessary before use. Common methods include acid-based rust removal devices, which spray an acidic solution onto the wire rod to remove rust, followed by rinsing with water to dilute the acid. However, this often results in incomplete cleaning and secondary corrosion of the steel strip, and acid washing no longer meets environmental protection requirements. Currently, physical rust removal machinery for wire rod generally uses a scale-breaking roller to remove rust from the surface. However, scale-breaking rollers have a relatively small contact area and a low single-pass rust removal rate. To solve the above technical problems, this invention provides a spiral rust removal device for wire rod. Summary of the Invention

[0003] The purpose of this invention is to provide a spiral rust removal device for wire rods. The device uses a combination of a central rotating drum, a feed connection end, a discharge connection end, a sand box, a bearing with a seat, polishing sand, and a spiral rust removal brush to perform multi-directional, multi-angle, and all-round cleaning and grinding on the wire rods passing through the central rotating drum, thereby improving the rust removal rate of the wire rods and solving the problem of low single-pass rust removal rate in mechanical rust removal.

[0004] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] This invention relates to a spiral rust removal device for wire rod, comprising a feed connection end bolted to the feed end of a central rotating drum; a discharge connection end bolted to the discharge end of the central rotating drum; the central rotating drum being disposed inside a sand box, with both the feed and discharge connection ends passing through the sand box; the feed and discharge connection ends being respectively mounted on a worktable via a bearing with a seat; the lower end of the sand box being fixed to the worktable with bolts; the central rotating drum comprising a circular tube, with several sand inlet holes formed on the circumferential side of one end of the circular tube near the feed connection end; several sand guide scrapers fixed on the circumferential side of the same end of the circular tube, cooperating with the sand inlet holes; several sand discharge holes formed on the circumferential side of the other end of the circular tube; polishing sand being stored together in the central rotating drum and the sand box; two sets of rust removal brushes, one set rotating to the left and the other to the right, being installed on the central rotating drum; and the polishing sand being circulated between the sand box and the central rotating drum.

[0006] As a preferred embodiment of the present invention, a first flange is fixed at the feed end of the circular tube to mate with the feed connection end; a second flange is fixed at the discharge end of the circular tube to mate with the discharge connection end; six sand inlet holes are opened on the circumferential side of the end of the circular tube near the first flange; six sand guide scrapers mate with the sand inlet holes are fixed on the circumferential side of the same end of the circular tube; two sets of brush body mounting holes for installing rust removal brushes are opened on the circumferential side of the circular tube, one set being left-handed and the other right-handed; the two sets of brush body mounting holes are arranged crosswise. The two sets of rust removal brushes installed on the central rotating drum are arranged in a cross-reverse spiral manner. As the wire rod passes through the central rotating drum, the rust removal brushes carry the internal polishing sand to simultaneously clean and grind the surface of the wire rod in multiple directions and angles, thereby improving the rust removal rate of the wire rod.

[0007] In a preferred embodiment of the present invention, the feed connection end includes a first cylinder that connects and mates with the bearing seat; a third flange that mates with the central rotating cylinder is fixed to the end of the first cylinder; a pulley is mounted on the circumferential side of the first cylinder; a row of first conical cylinders is fixed axially inside the first cylinder; the constricted ends of the first conical cylinders point towards the wire rod discharge direction. The feed connection end, serving as a power input end, effectively prevents polishing sand from overflowing by incorporating the first conical cylinders, while also guiding the wire rod.

[0008] In a preferred embodiment of the present invention, the discharge connection end includes a second cylinder that connects and mates with the bearing seat; a fourth flange that mates with the feed connection end is fixed to the end of the second cylinder; a second conical cylinder is coaxially arranged inside the second cylinder; the constricted end of the second conical cylinder points towards the wire rod discharge direction. The second conical cylinder built into the discharge connection end effectively prevents polishing sand from overflowing and also guides the wire rod.

[0009] As a preferred embodiment of the present invention, the sand box includes a rectangular base box, an inner liner box, and a box cover; the lower end of the inner liner box is fixed inside the rectangular base box; the lower end of the rectangular base box is provided with a rectangular flange for connection and cooperation with the workbench; the inner liner box includes two upright plates, the upper ends of which are semi-circular, and the two upright plates are respectively fixed at both ends inside the rectangular base box; the upper half of the two upright plates are respectively provided with through holes for the feed connection end and the discharge connection end to pass through; an inclined sand guide plate is fixed between the opposite surfaces of the two upright plates, and the lower end of the sand guide plate is located at the sand inlet end of the central rotating cylinder; the box cover is placed on the central rotating cylinder, and the lower end of the box cover is connected to the upper end of the rectangular base box by four quick buckles. The polishing sand in the sand box slides down the slope on the sand guide plate to one end below the sand guide scraper. As the central drum rotates, the sand guide scraper picks up the polishing sand and slides along the sand guide scraper through the sand inlet hole into the interior of the central drum to participate in the polishing of rust on the surface of the wire rod. The polishing sand falls back onto the sand guide plate from the sand outlet hole at the other end to participate in the circulation. The sand box setting is conducive to the recycling of polishing sand, and the system can operate stably for a long time.

[0010] As a preferred embodiment of the present invention, the rust-removing brush includes a rectangular block; an inner lining support plate whose opposite side at the inner end of the rectangular block mates with the inner wall of the central rotating cylinder; a pressure nozzle is provided at the inner end of the rectangular block; several bristles are pressed and fixed on the pressure nozzle; a threaded rod is fixed at the outer end of the rectangular block; a flat washer, a spring washer, and a nut are sequentially installed on the threaded rod. The rust-removing brush adopts a kit structure, which is convenient for installation and positioning and has low replacement cost. The spirally arranged rust-removing brush effectively drives the polishing abrasive and acts on the surface of the wire rod.

[0011] As a preferred embodiment of the present invention, the bristles are made of wear-resistant steel. Using wear-resistant steel for the bristles improves the scraping effect on the wire rod surface while reducing wear during the scraping process involving the polishing abrasive.

[0012] The present invention has the following beneficial effects:

[0013] This invention utilizes a central rotating drum, a feed connection end, a discharge connection end, a sand box, polishing sand, and two sets of bidirectional double-screw rust-removing brushes mounted on the central rotating drum. Under high-speed rotation, the polishing sand circulates between the central rotating drum and the sand box. The polishing sand and the bidirectional double-screw rust-removing brushes perform multi-directional, multi-angle, and all-round cleaning and grinding on the wire rod passing through the central rotating drum, thereby improving the rust removal rate of the wire rod.

[0014] The combination of the central rotating drum, the feed connection end, and the discharge connection end of this invention ensures high-speed rotation while effectively preventing polishing sand from overflowing. It also works with the sand box to ensure efficient and long-term internal circulation, resulting in stable rust removal efficiency for wire rods.

[0015] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Specific Implementation

[0029] Please see Figure 1-9 As shown, this invention is a spiral rust removal device for wire rod, comprising a central rotating drum 1, a feed connection end 2, a discharge connection end 3, and a sand box 4; the feed connection end 2 is bolted to the feed end of the central rotating drum 1; the discharge connection end 3 is bolted to the discharge end of the central rotating drum 1; the central rotating drum 1 is disposed inside the sand box 4, and both the feed connection end 2 and the discharge connection end 3 pass through the sand box 4; the feed connection end 2 and the discharge connection end 3 are respectively mounted on a worktable via a bearing 5; the lower end of the sand box 4 is bolted to... On the workbench, the central rotating drum 1 and the sand box 4 are both filled with circulating polishing sand 6. The central rotating drum 1 includes a round tube 11, and six sand inlet holes 14 are opened on the circumferential side of one end of the round tube 11 near the feed connection end 2. Six sand guide scrapers 15 that cooperate with the sand inlet holes 14 are fixed on the circumferential side of the same end of the round tube 11. Sand discharge holes 16 are opened on the circumferential side of the other end of the round tube 11. Two sets of rust removal brushes 7 with left-hand and right-hand rotation are installed on the central rotating drum 1, and the two sets of rust removal brushes 7 are installed on the central rotating drum 1 in a bidirectional double spiral.

[0030] The central rotating drum 1 is the core component for rust removal. Specifically, the central rotating drum 1 includes a circular tube 11; a first flange 12, which mates with the feed connection end 2, is fixed at the feed end of the circular tube 11; a second flange 13, which mates with the discharge connection end 3, is fixed at the discharge end of the circular tube 11; two sets of brush body mounting holes 17, one left-handed and one right-handed, are opened on the circumferential side of the circular tube 11 for mounting the rust removal brushes 7; the two sets of brush body mounting holes 17 are arranged crosswise. The two sets of rust removal brushes 7 installed on the central rotating drum 1 are arranged in a crosswise reverse spiral manner. As the wire rod passes through the central rotating drum 1, the rust removal brushes 7, carrying the internal polishing sand 6, simultaneously clean and grind the surface of the wire rod in multiple directions and angles, thereby improving the rust removal rate of the wire rod.

[0031] The feed connection end 2 serves as a rotating support end and the entry point for wire rod rust removal, requiring measures to prevent the polishing sand 6 inside the central rotating drum 1 from overflowing. Specifically, the feed connection end 2 includes a first cylinder 21 that connects and mates with a bearing 5; a third flange 22 that mates with the central rotating drum 1 is fixed to the end of the first cylinder 21, and the third flange 22 is bolted to the first flange 12; a pulley 23 is installed on the circumferential side of the first cylinder 21; and a row of first cones 24 are fixed axially inside the first cylinder 21; the constricted ends of the first cones 24 point towards the wire rod discharge direction. The design of multiple cones effectively prevents the polishing sand 6 from overflowing. The external power source drives the connection end 2, the central rotating drum 1, the discharge connection end 3, and two sets of rust removal brushes 7 spirally installed in two directions to rotate at high speed via a belt and pulley 23.

[0032] The discharge connection end 3 serves as another rotating support and, as the output end for wire rod rust removal, needs to prevent the polishing sand 6 inside the central rotating drum 1 from overflowing. Specifically, the discharge connection end 3 includes a second cylinder 31 that connects and mates with the bearing 5; a fourth flange 32 that mates with the feed connection end 2 is fixed to the end of the second cylinder 31, and the fourth flange 32 is bolted to the second flange 13; a second conical cylinder 33 is fixed coaxially inside the second cylinder 31; the constricted end of the second conical cylinder 33 points towards the wire rod discharge direction. The design of the second conical cylinder 33 effectively prevents the polishing sand 6 from overflowing.

[0033] The sand box 4 serves as a circulating component for the polishing sand 6. Specifically, the sand box 4 includes a rectangular base box 41, an inner liner box 42, and a box cover 43. The lower end of the inner liner box 42 is fixed inside the rectangular base box 41. The lower end of the rectangular base box 41 is provided with a rectangular flange 411 that connects and mates with the workbench. The inner liner box 42 includes two upright plates 421, with the upper end of the upright plates 421 being semi-circular. The two upright plates 421 are respectively fixed at both ends inside the rectangular base box 41. The upper half of the two upright plates 421 is respectively provided with through holes 422 for the feed connection end 2 and the discharge connection end 3 to pass through. An inclined sand guide plate 423 is fixed between the opposing surfaces of the two upright plates 421, with the lower end of the sand guide plate 423 located at the sand inlet end of the central rotating drum 1. The box cover 43 covers the central rotating drum 1, and the lower end of the box cover 43 is connected to the upper end of the rectangular base box 41 by four quick-release buckles. The polishing sand 6 is circulated as follows: the polishing sand 6 in the sand box 4 slides down the slope on the sand guide plate 423 to one end below the sand guide scraper 15. During the rotation of the central rotating drum 1, the sand guide scraper 15 scoops up the polishing sand 6 and slides along the sand guide scraper 15 from the sand inlet hole 14 into the interior of the central rotating drum 1 to participate in the polishing of the rust on the surface of the wire rod. The polishing sand 6 falls back onto the sand guide plate 423 from the sand outlet hole 16 at the other end to participate in the circulation.

[0034] The rust removal brush 7 is a crucial component, requiring stable installation and durable use. Specifically, the rust removal brush 7 includes a rectangular block 71; an inner support plate 72 whose opposite side at the inner end of the rectangular block 71 mates with the inner wall of the central rotating cylinder 1; a pressure nozzle at the inner end of the rectangular block 71; several brush bristles 73 pressed and fixed onto the pressure nozzle; and a threaded rod 74 fixed to the outer end of the rectangular block 71. A flat washer 75, a spring washer 76, and a nut 77 are sequentially installed on the threaded rod 74. The brush bristles 73 are made of wear-resistant steel, which has high agitation resistance to polishing abrasive and allows for long-term cleaning and use.
