Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ship painting waste recycling, in particular to a steel sand recycling device. BACKGROUND

[0002] Before the painting operation, the surface of the ship steel must be pretreated, and sand blasting is the core process. Through high-pressure steel sand spraying, the impact force and grinding effect of the steel sand particles are used to remove the oxide skin, rust layer, old paint and other impurities on the surface of the ship, so as to form a roughness on the steel surface that meets the painting requirements, and provide a basis for the firm combination of the coating and the substrate.

[0003] After the sand blasting process, the steel sand attached to the surface of the ship usually needs to be cleaned and recycled. On the one hand, it avoids the impact of residual steel sand on the subsequent painting quality; on the other hand, as the main consumable for sand blasting, the single use amount of steel sand is large (tens of tons of steel sand are needed for sand blasting before painting a medium-sized ship), and recycling and screening qualified steel sand for reuse can greatly reduce the amount of steel sand purchased, saving costs for enterprises.

[0004] However, the current steel sand recycling in the ship painting stage is still mainly based on the traditional method of "manual cooperation with broom and shovel". This method has many disadvantages that are difficult to overcome in the complex operation scene of the ship: 1. The steel sand scattered on the deck surface has a wide range, and the operator needs to bend down repeatedly to pick up and carry, with a high proportion of invalid actions, resulting in very low efficiency for a single person; 2. In the ship painting environment, steel sand will mix with paint residues, wood chips, welding slag, iron rust debris and other non-ferrous garbage. Manual recycling cannot distinguish between the two, and only the mixed garbage can be collected. When these impurities enter the subsequent steel sand filtering and screening process, they will clog the filter screen of the filtering equipment and wear out the screening components. At the same time, additional manpower is needed for secondary sorting, further increasing production costs; 3. During the manual cleaning process, the operator needs to bend down for a long time and carry heavy objects, which can easily cause occupational diseases such as lumbar injury and muscle strain. At the same time, the dust (such as iron rust dust and steel sand debris) generated during cleaning will diffuse in the enclosed space such as the cabin, and the operator will inhale it, which can easily cause respiratory diseases and does not meet the requirements of occupational health and safety. SUMMARY

[0005] The purpose of the present application is to provide a steel sand recycling device to solve the technical problems in the prior art that the current manual cleaning method cannot meet the needs of efficient and thorough recycling of steel sand in the ship painting stage, and has high cost, difficult sorting and poor safety.

[0006] According to a first aspect of the present application, a steel sand recycling device is provided, which comprises a frame body, a magnetic roller and a recycling part, the magnetic roller and the recycling part both extend along a first direction, and the magnetic roller is rotatably arranged on the frame body. The recycling part has a containing groove containing the waste to be recycled, the containing groove is formed with a feeding port at one end of the recycling part in the second direction, the magnetic roller and the recycling part are arranged side by side along the third direction, and one side edge of the feeding port abuts against the surface of the magnetic roller, the first direction intersects the third direction, and the second direction intersects the plane determined by the first direction and the third direction.

[0007] Preferably, a wheel is further included, the wheel is arranged at the bottom of the frame body, and the wheel is coaxially arranged with the magnetic roller, so that when the frame body is pushed, the rotation of the wheel can drive the rotation of the magnetic roller. Both sides of the magnetic roller in the first direction are provided with the wheel.

[0008] Preferably, the radius of the wheel is greater than the radius of the magnetic roller.

[0009] Preferably, the difference between the radius of the wheel and the radius of the magnetic roller is 2cm-5cm.

[0010] Preferably, the magnetic roller is a hollow roller.

[0011] Preferably, the frame body includes a support frame and a hand-held frame, the magnetic roller and the recycling part are arranged on the support frame, the hand-held frame is arranged on the side of the magnetic roller away from the recycling part in the third direction, and the hand-held frame is fixedly connected with the support frame.

[0012] Preferably, an unloading assembly is further included, the unloading assembly includes a driving part and a connecting rod part, the driving part is arranged at one end of the hand-held frame away from the support frame, one end of the connecting rod part is hinged with the driving part, the other end of the connecting rod part is hinged with the recycling part, and the recycling part is rotatably arranged on the support frame, so that when the driving part is driven to rotate, the connecting rod part can pull the feeding port of the recycling part to tilt away from the magnetic roller, to pour out the waste to be recycled in the recycling part.

[0013] Preferably, the driving part includes a rotating shaft, a wrench and a swing rod, the rotating shaft extends along the first direction, and the rotating shaft is rotatably arranged on the hand-held frame. The wrench and the swing rod are fixedly arranged on the rotating shaft, and one end of the connecting rod part away from the rotating shaft is hinged with the swing rod. The wrench and the swing rod are arranged at a predetermined angle with each other when viewed in the first direction.

[0014] Preferably, there are two swing arms and two connecting rods. The two connecting rods are respectively hinged to the two ends of the recovery part in the first direction. The two swing arms are spaced apart along the extension direction of the rotation axis, and the connecting rods are hinged to the swing arms one-to-one.

[0015] Preferably, the frame further includes a support leg that extends along the second direction and is fixedly disposed at one end of the support frame that is connected to the handrail frame. The support leg and the handrail frame are respectively disposed on both sides of the support frame in the second direction.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: The steel shot recycling device provided in this application, by setting a rotatable magnetic suction roller, utilizes the magnetic suction roller's adsorption effect on steel shot. On the one hand, the magnetic suction roller actively adsorbs steel shot during rotation, eliminating the need for manual bending over to sweep or pick up, and directly solving the problems of difficult movement of steel shot and high labor intensity in traditional manual recycling. The magnetic roller uses magnetic force to attract scattered steel shot to its surface, replacing the manual handling of steel shot and greatly reducing labor consumption. Moreover, the magnetic roller's selective attraction of steel shot prevents non-ferrous waste from being attracted to its surface during the pickup process. This achieves initial separation of steel shot and non-ferrous waste as the steel shot is scraped off into the recycling section, reducing the amount of non-ferrous waste entering the recycling section, lowering the burden on subsequent filtration processes, and thus reducing equipment maintenance and consumable replacement costs. It also solves the problem of traditional manual recycling not being able to achieve standardized sorting. On the other hand, the rotatable design of the magnetic roller, with the magnetic roller and recycling section arranged side by side along a third direction and the structure where the edge of the feed inlet abuts against the surface of the magnetic roller, allows the steel shot attracted during the rotation of the magnetic roller to be scraped off at the contact point by the edge of the feed inlet and fall directly into the receiving tank of the recycling section, achieving a seamless connection from steel shot attraction to collection. This design not only allows the steel shot adsorbed on its surface to be transported to the recycling section as the roller rotates, preventing excessive accumulation of steel shot on the magnetic roller surface and thus achieving continuous steel shot recycling, but also prevents secondary scattering of steel shot during transportation, further improving the thoroughness of steel shot recycling. Simultaneously, the scraping-type collection method eliminates the need for additional power to drive the steel shot transfer, simplifying the device structure and reducing equipment costs. Compared to intermittent manual cleaning, it significantly improves recycling efficiency and effectively avoids dust problems caused by manual cleaning, ensuring a clean working environment and the health and safety of operators. Furthermore, the design of the magnetic roller extending along the first direction expands its adsorption range, enabling it to adsorb steel shot scattered over a larger area at once. Addressing the dispersed nature of falling steel shot, this reduces the number of times the device needs to be turned around during recycling, further improving recycling efficiency and solving the problems of excessive turnover and wasted effort in traditional manual recycling.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] The following reference Figures 1 to 3 This application describes a steel shot recycling apparatus according to some embodiments.

[0027] See Figures 1 to 3 As shown, an embodiment of the first aspect of this application provides a steel shot recycling device, which includes a frame, a magnetic roller 2, and a recycling section 3. Both the magnetic roller 2 and the recycling section 3 extend along a first direction F1, and the magnetic roller 2 is rotatably mounted on the frame. The recycling section 3 has a receiving groove for receiving waste material to be recycled (e.g., steel shot). An inlet is formed at one end of the receiving groove in a second direction F2. The magnetic roller 2 and the recycling section 3 are arranged side by side along a third direction F3, and one edge of the inlet abuts against the surface of the magnetic roller 2. The first direction F1 intersects the third direction F3, and the second direction F2 intersects the plane defined by the first direction F1 and the third direction F3.

[0028] According to the steel shot recycling device provided by the above technical features, by setting a rotatable magnetic suction roller 2, the magnetic suction roller 2 uses the adsorption effect of the magnetic suction roller 2 to actively adsorb steel shot during the rotation process. This not only eliminates the need for manual bending over to sweep or pick up, but also directly solves the problems of difficult movement of steel shot and high labor intensity in traditional manual recycling. The magnetic roller 2 uses magnetic force to attract scattered steel shot to its surface, replacing the manual handling of steel shot and greatly reducing labor consumption. Moreover, the magnetic attraction of the magnetic roller 2 for steel shot means that non-ferrous waste will not be attracted to the surface of the magnetic roller 2 during the picking process. Thus, as the steel shot is scraped off to the recycling section 3, the steel shot and non-ferrous waste are initially separated, reducing the amount of non-ferrous waste entering the recycling section 3, reducing the burden on subsequent filtration processes, and thus reducing equipment maintenance and consumable replacement costs. This solves the problem that traditional manual recycling cannot achieve standardized sorting. On the other hand, the rotatable setting of the magnetic roller 2, combined with the parallel arrangement of the magnetic roller 2 and the recycling section 3 along the third direction F3, and the structure of the edge of the feed inlet abutting against the surface of the magnetic roller 2, allows the steel shot attracted by the magnetic roller 2 during rotation to be scraped off by the edge of the feed inlet at the contact point and fall directly into the receiving tank of the recycling section 3, achieving a seamless connection from steel shot attraction to collection. This design not only allows the steel shot adsorbed on its surface to be transported to the recycling section 3 as the roller rotates, preventing excessive accumulation of steel shot on the surface of the magnetic roller 2 and thus achieving continuous steel shot recycling, but also prevents secondary scattering of steel shot during transportation, further improving the thoroughness of steel shot recycling. Simultaneously, the scraping-type collection method eliminates the need for additional power to drive the steel shot transfer, simplifying the device structure and reducing equipment costs. Compared to intermittent manual cleaning, it significantly improves recycling efficiency and effectively avoids dust problems caused by manual cleaning, ensuring a clean working environment and the health and safety of operators. Furthermore, the structural design of the magnetic roller 2 extending along the first direction F1 expands its adsorption range, enabling it to adsorb steel shot scattered over a larger area at once. Addressing the dispersed nature of falling steel shot, this reduces the number of times the device needs to be turned around during recycling, further improving recycling efficiency and solving the problems of excessive turnover and wasted effort in traditional manual recycling.

[0029] like Figures 1 to 3 As shown in the figure, F1 can be an example of the first direction F1 mentioned above, F2 can be an example of the second direction F2 mentioned above, and F3 can be an example of the third direction F3 mentioned above. Preferably, any two of the first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other to improve the assembly stability of the steel shot recycling device.

[0030] Preferably, such as Figures 1 to 3As shown, the aforementioned steel shot recovery device may also include wheels 4, which are located at the bottom of the frame and coaxially mounted with the magnetic roller 2. When the frame is pushed, the rotation of the wheels 4 drives the magnetic roller 2 to rotate. Thus, on the one hand, the wheels 4 at the bottom of the frame provide mobility for the device. The operator does not need to carry the entire device; simply pushing the frame is sufficient to move the device within the work area, significantly reducing the labor intensity of moving the device. This is particularly suitable for open environments such as large factories or ship decks, improving the device's mobility. On the other hand, it achieves linkage between the device's movement and the rotation of the magnetic roller 2, eliminating the need for an additional power source (such as a motor) for the magnetic roller 2. When the frame is pushed, the rotation of the wheels 4 directly drives the magnetic roller 2 to rotate via coaxial transmission, saving the cost and installation space of additional power equipment and avoiding the additional action of manually operating the magnetic roller 2. Meanwhile, the rotation speed of the magnetic roller 2 can be adjusted synchronously with the moving speed of the device to ensure that the magnetic roller 2 continuously adsorbs steel sand during the movement of the device, avoiding the accumulation of steel sand or untimely adsorption caused by the magnetic roller 2 stopping, thus improving the continuity and efficiency of recycling.

[0031] Preferably, such as Figure 1 and Figure 3 As shown, wheels 4 are provided on both sides of the magnetic roller 2 in the first direction F1. This ensures balanced force distribution on the device in the first direction F1, preventing tilting caused by a single wheel 4. When the device is pushed, the wheels 4 on both sides rotate synchronously, ensuring the magnetic roller 2 remains horizontal at all times. This prevents the problem of "weak adsorption on one side and steel shot accumulation on the other" caused by tilting the magnetic roller 2, ensuring adsorption stability throughout the entire length of the magnetic roller 2, and also extending the service life of the magnetic roller 2 and wheels 4.

[0032] Preferably, such as Figure 1 and Figure 3 As shown, the radius of the wheel 4 can be larger than the radius of the magnetic roller 2, so that the magnetic roller 2 will not directly contact the ground or work surface when the device is placed or moved. On the one hand, this avoids surface wear caused by friction between the magnetic roller 2 and the ground, extending the service life of the magnetic roller 2; on the other hand, the gap between the magnetic roller 2 and the ground can accommodate scattered steel sand particles, ensuring that the steel sand can be smoothly adsorbed by the magnetic roller 2, preventing problems such as "steel sand being crushed and unable to be adsorbed" or "ground impurities scratching the magnetic roller 2" caused by the magnetic roller 2 being close to the ground, thus ensuring the adsorption efficiency and reliability of the magnetic roller 2.

[0033] Preferably, such as Figure 3 As shown, the difference between the radius of the wheel 4 and the radius of the magnetic roller 2 (i.e. Figure 3The radius difference (ΔR) shown can be 2cm to 5cm. If the radius difference is less than 2cm, the gap between the magnetic roller 2 and the ground is too small, making it easy for large particles of impurities to get stuck or scratched. If the radius difference is greater than 5cm, the gap may be too large, causing fine steel sand particles to be unable to be attracted due to "being too far from the magnetic roller 2 and having insufficient magnetic force," thus reducing the thoroughness of the recycling. A radius difference of 2cm to 5cm can ensure that most of the scattered steel sand (conventional steel sand particles with a diameter of 0.1mm to 3mm) can be effectively attracted by the magnetic roller 2, while avoiding contact between ground impurities and the magnetic roller 2. At the same time, it can ensure the stability of the center of gravity when the device moves, preventing the device from shaking due to excessive gap.

[0034] Preferably, the magnetic roller 2 can be a hollow roller, which significantly reduces the material usage and weight of the magnetic roller 2 while ensuring magnetic attraction performance (the magnetic material can be attached to the inner or outer wall of the hollow roller). On the one hand, the overall weight of the device is reduced, making it easier for the operator to push the frame, especially suitable for scenarios such as going up or down slopes or narrow passages, reducing the labor intensity during movement. Moreover, the reduced weight can reduce the load on the frame and wheels 4, extend the service life of the connecting parts between the wheels 4 and the frame, and avoid the risk of "accidental tipping and injury" caused by excessive weight of the device, thus improving operational safety. On the other hand, it effectively reduces the manufacturing cost of the magnetic roller 2.

[0035] In an embodiment, such as Figures 1 to 3 As shown, the aforementioned frame may include a support frame 11 and a handrail frame 12. Both the magnetic roller 2 and the recycling section 3 are mounted on the support frame 11. The handrail frame 12 is located on the side of the magnetic roller 2 away from the recycling section 3 in the third direction F3, and is fixedly connected to the support frame 11. Thus, on the one hand, by fixing the magnetic roller 2 and the recycling section 3, which need to be close to the bottom surface, to the support frame 11, and by placing the handrail frame 12 on one side of the support frame 11, the operator can easily push the frame to rotate the wheels 4 to operate the steel shot recycling device without bending over, effectively improving operational convenience and recycling reliability. On the other hand, placing the handrail frame 12 and the recycling section 3 on both sides of the magnetic roller 2 conforms to ergonomic design. Figure 2 Taking the shown orientation as an example, when the operator faces the push handle frame 12 and moves forward and to the right (i.e., pushes the steel shot recycling device forward), the magnetic roller 2 rotates clockwise. The point of the magnetic roller 2 closest to the ground is located upstream of the rotating part 3, which is just enough to transport the waste to be recycled from the ground to the recycling part 3 through the rotation of the magnetic roller 2. The operator can intuitively observe the adsorption status of the magnetic roller 2 and the holding status of the recycling part 3, which makes it easy to adjust the moving speed of the device or clean the recycling part 3 in time, avoiding the problems of "steel shot overflowing into the recycling part 3" or "magnetic roller 2 being full without being noticed" caused by obstructed vision, thus improving the convenience of operation and the reliability of recycling.

[0036] Preferably, such asFigures 1 to 3 As shown, the support frame 11 can be a rectangular frame, which can be arranged parallel to the plane defined by the first direction F1 and the third direction F3. The shafts of the magnetic roller 2 and the wheel 4 can be mounted on the support frame 11 via bearings to ensure the rotatability of the magnetic roller 2 and the wheel 4.

[0037] Preferably, such as Figures 1 to 3 As shown, the aforementioned handrail frame 12 may include two diagonal bars 121 and two handrails 122. The diagonal bars 121 are fixedly installed at the end of the support frame 11 in the third direction F3 away from the recycling part 3, and the two diagonal bars 121 are respectively installed at both ends of the support frame 11 in the first direction F1. The two handrails 122 are respectively installed at the ends of the two diagonal bars 121 away from the support frame 11, so that the operator can push the steel shot recycling device with both hands and ensure the smooth pushing of the steel shot recycling device.

[0038] Optionally, such as Figure 1 and Figure 3 As shown, the aforementioned handrail frame 12 may also include a reinforcing plate 123, which connects two diagonal bars 121 to increase the stability and support strength of the handrail frame 12.

[0039] Preferably, such as Figure 2 and Figure 3 As shown, the frame may also include a support leg 13, which extends along the second direction F2 and is fixedly mounted on the end of the support frame 11 that is connected to the handrail frame 12. The support leg 13 and the handrail frame 12 are respectively mounted on both sides of the support frame 11 in the second direction F2. Thus, the support leg 13 provides a "stable parking support" for the device. When the device does not need to be moved or the operator needs to stop working, the support leg 13 can support the device together with the wheel 4 to prevent the device from sliding due to ground tilt or accidental collision, thereby improving the parking stability of the device.

[0040] Optionally, such as Figure 2 As shown, the frame may also include a reinforcing rib 131, which can connect the diagonal bar 121 and the support leg 13 to improve the support strength of the support leg 13.

[0041] Preferably, such as Figure 3 As shown, there can be two support legs 13, which are respectively set to correspond to the two diagonal bars 121, thereby improving the support stability of the support legs 13.

[0042] In an embodiment, preferably, such as Figures 1 to 3As shown, the above-mentioned steel shot recycling device may also include an unloading assembly. Specifically, the unloading assembly may include a drive unit and a connecting rod 51. The drive unit is located at the end of the handrail frame 12 away from the support frame 11. One end of the connecting rod 51 is hinged to the drive unit, and the other end of the connecting rod 51 is hinged to the recycling unit 3. The recycling unit 3 is rotatably mounted on the support frame 11 so that when the drive unit rotates, the connecting rod 51 can pull the feed inlet of the recycling unit 3 to tilt away from the magnetic roller 2, so as to pour out the waste material to be recycled in the recycling unit 3. In this way, on the one hand, the rotatable structure of the recycling unit 3, in conjunction with the drive unit driving the connecting rod 51, can easily pull the recycling unit 3 to tilt, realizing the rapid unloading of steel shot. The recycling unit 3 does not need to be manually moved, reducing the labor intensity of unloading and avoiding secondary scattering of steel shot during the unloading process. On the other hand, the drive unit is located close to the operator's operating end, so the operator can operate the unloading without moving or bending over, effectively improving the convenience of steel shot unloading.

[0043] Preferably, such as Figures 1 to 3 As shown, the aforementioned drive unit may include a rotating shaft 521, a wrench 522, and a swing arm 523. The rotating shaft 521 extends along a first direction F1 and is rotatably mounted on the handrail frame 12. The wrench 522 and the swing arm 523 are both fixedly mounted on the rotating shaft 521. The connecting rod 51 is hinged to the end of the swing arm 523 away from the rotating shaft 521. When viewed along the first direction F1, the wrench 522 and the swing arm 523 are at a predetermined angle. Thus, on the one hand, the wrench 522 serves as the operating end, driving the swing arm 523 to rotate via the rotating shaft 521, converting the "operator's rotational force" into the "swinging force of the swing arm 523," and then pulling the retraction unit 3 to tilt via the connecting rod 51. This structure features a force-saving lever design (the length of the wrench 522 is greater than the length of the swing arm 523). The operator only needs to turn the wrench 522 with a small force to drive the swing arm 523 to produce a large swing amplitude, easily achieving the tilting unloading of the recovery section 3. This solves the problem of "manually pulling the recovery section 3 is laborious" and is especially suitable for scenarios where there is a large accumulation of steel shot and a large weight in the recovery section 3. On the other hand, the predetermined angle (such as 60°~120°) ensures that the operating direction of the wrench 522 matches the swing direction of the swing arm 523, avoiding interference between the two movements.

[0044] Preferably, such as Figure 1 and Figure 3As shown, the number of the aforementioned swing rods 523 and connecting rods 51 can both be two. The two connecting rods 51 are respectively hinged to both ends of the recovery section 3 in the first direction F1. The two swing rods 523 are spaced apart along the extension direction of the rotation axis 521. The connecting rods 51 and the swing rods 523 are hinged one-to-one. In this way, the recovery section 3 is subjected to "synchronous force at both ends" when tilting, avoiding uneven tilting of the recovery section 3 caused by pulling on only one side of the connecting rod 51. If the connecting rod 51 is only set on one side, the recovery section 3 is prone to "one end high and one end low" when tilting, resulting in steel sand accumulating in the recovery section 3 or incomplete dumping. Synchronous pulling at both ends can ensure that the recovery section 3 remains horizontally tilted along the first direction F1, and the steel sand can be dumped evenly from the feed port, improving the thoroughness of unloading. At the same time, it can avoid deformation of the recovery section 3 or damage to the connecting parts caused by uneven force, and extend the service life of the recovery section 3.

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.
