Shot blasting device for steel structure of wind power project processing plant, processing plant and method

Abstract

The application belongs to the technical field of shot blasting derusting devices, and proposes a wind power project processing plant steel structure shot blasting derusting device, a processing plant and a method. Two derusting parts are hingedly connected at one end, and the inner sides of the two derusting parts are both provided with containing cavities for containing steel structures. When derusting the steel structures, the steel structures are contained in the containing cavities, thereby reducing the pollution of dust to the external environment, and especially avoiding the harm of dust arbitrarily spreading in the plant to the workers. A steel ball recycling gap is formed in the containing cavity, and a second steel ball launching assembly is arranged in the steel ball recycling gap. After the steel balls launched by the first steel ball launching assembly complete the derusting of the steel structures, the steel balls drop into the second steel ball launching assembly through the steel ball recycling gap. After the second steel ball launching assembly launches the recycled steel balls, the steel balls re-enter the first steel ball launching assembly through the channel, and the repeated derusting and utilization of the steel balls are realized, thereby avoiding the problem of shutdown during the recycling and reuse of the steel balls, and ensuring the derusting efficiency.

Description

Technical Field

[0001] This invention belongs to the technical field of shot blasting and rust removal equipment, and particularly relates to a shot blasting and rust removal device, processing workshop and method for steel structures in wind power project processing plants. Background Technology

[0002] When removing rust from steel structure monopiles, towers, cages, and stabilization platforms in offshore wind power project processing plants, sandblasting is generally used. However, when the steel structure has been left idle for a long time and the rust is severe, it is difficult to completely remove the rust using ordinary sandblasting equipment when the project resumes. In this case, shot blasting is required, which can significantly improve the effect of rust removal.

[0003] The inventors discovered that when removing rust from steel structures in wind power project processing plants, the large size of the objects to be rusted and the long rust removal time mean that if rust removal is carried out outside the workshop, it will cause serious air pollution; while rust removal inside the workshop will not cause serious air pollution, but may aggravate occupational diseases of processing workers. There is no suitable environmentally friendly shot blasting method. Furthermore, the shot blasting equipment currently used for rust removal of steel structures in wind power project processing plants wastes a lot of steel shot during the rust removal process and requires a large quantity of steel shot. Although steel shot can be recycled, it requires different shutdowns and reloading of steel shot, which seriously affects the efficiency of rust removal of steel structures in wind power project processing plants. Summary of the Invention

The steel structure is housed within a containment cavity, reducing dust pollution to the external environment and, in particular, preventing dust from spreading arbitrarily within the plant and harming workers. A steel shot recovery gap is provided within the containment cavity, and a second steel shot launching component is installed within this gap. A channel connects the second and first steel shot launching components. After the steel shot launched by the first component removes rust from the steel structure, it falls through the recovery gap into the second component. The second component then launches the recovered steel shot, which then re-enters the first component through the channel for repeated rust removal. This avoids downtime during steel shot recycling and ensures efficient rust removal of steel structures in wind power project processing plants.

A steel shot recovery gap is provided at the end of the cavity away from the drive mechanism. A second steel shot launching assembly is provided in the steel shot recovery gap.

[0012] Furthermore, the channel is configured as an arc-shaped channel; a fan is provided on one side of the rust removal section.

[0013] Furthermore, the first steel shot launching assembly includes a first launching cavity, a first electromagnet disposed at the bottom of the first launching cavity, a first spring disposed inside the first launching cavity and connected at one end to the first electromagnet, a first magnet plate connected to the other end of the first spring, a first controller connected to the first electromagnet, and a first isolation layer disposed outside the first launching cavity.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0032] Example 1:

[0033] The rust removal method used for steel structure monopiles, towers, cages, and stabilization platforms in offshore wind power project processing plants is generally sandblasting. While the dust generated during rust removal inside the workshop doesn't severely pollute the atmosphere, it may exacerbate occupational diseases among processing workers, such as pneumoconiosis. Sandblasting outside the workshop causes severe air pollution, significantly increasing PM10 levels and potentially leading to work stoppages during environmental inspections. The above methods address minor rust formation on steel components. However, if a project is halted for an extended period and rust is severe, ordinary sandblasting equipment is unlikely to eradicate the rust upon project resumption. Shot blasting can significantly improve the rust removal effect, but it faces the same problems as sandblasting and is more expensive, resulting in material waste. To provide a better working environment for workers, reduce costs, and avoid work stoppage risks, a closed-loop shot blasting system can be used. This avoids the above risks and significantly improves construction efficiency.

[0034] As described in the background section, there is currently no suitable environmentally friendly shot blasting method for rust removal. Furthermore, the shot blasting equipment currently used for rust removal of steel structures in wind power project processing plants suffers from significant waste of steel shot during the rust removal process and requires a large quantity of steel shot. Although steel shot can be recycled, it requires different shutdowns and reloading of the steel shot, which seriously affects the efficiency of rust removal of steel structures in wind power project processing plants.

[0035] In response to the above problems, such as Figure 1 As shown, this embodiment provides a shot blasting and rust removal device for steel structures in wind power project processing plants, including a drive mechanism 1 and a shot blasting and rust removal mechanism 3 suspended on the drive mechanism 1;

[0036] like Figure 1 and Figure 3 As shown, the shot blasting and rust removal mechanism 3 includes two rust removal sections 302, which are hinged at one end near the drive mechanism 1. Each of the two rust removal sections 302 has a receiving cavity 3021 for accommodating the steel structure 5 on its inner side. A first steel shot launching assembly 3022 is provided on the inner wall of the receiving cavity 3021. A steel shot recovery gap 3024 is provided at one end of the receiving cavity 3021 away from the drive mechanism 1. A second steel shot launching assembly 3025 is provided in the steel shot recovery gap 3024. A channel 3026 is provided between the second steel shot launching assembly 3025 and the first steel shot launching assembly 3024.

[0037] Specifically, the two rust removal sections 302 are hinged at one end. Each of the two rust removal sections 302 has an inner cavity 3021 for accommodating the steel structure 5. A first steel shot launching assembly 3022 is installed on the inner wall of the cavity 3021. When removing rust from the steel structure 5, it is housed within the cavity 3021, reducing dust pollution to the external environment and, in particular, preventing dust from spreading arbitrarily within the factory and harming workers. A steel shot recovery gap 3024 is provided within the cavity 3021, and a second steel shot launching assembly 3025 is installed within the steel shot recovery gap 3024. The second steel shot is launched... A channel 3026 is provided between component 3025 and the first steel shot launching component 3022. After the steel shot 3023 launched by the first steel shot launching component 3022 removes rust from the steel structure 5, it falls into the second steel shot launching component 3025 through the steel shot recovery gap 3024. After the second steel shot launching component 3025 launches the recovered steel shot 3023, it re-enters the first steel shot launching component 3022 through the channel 3026 for repeated rust removal. This avoids the problem of downtime when the steel shot 3023 is recycled and reused, and ensures the rust removal efficiency of the steel structure of the wind power project processing plant.

[0038] In some embodiments, optionally, such as Figure 2 As shown, multiple first steel shot launching assemblies 3022 are evenly spaced within the receiving cavity 3021; ​​the number of second steel shot launching assemblies 3025 is the same as the number of first steel shot launching assemblies 3022, and each second steel shot launching assembly 3025 is connected to a first steel shot launching assembly 3022 via a channel 3026. The evenly spaced arrangement of multiple first steel shot launching assemblies 3022 ensures effective rust removal of the steel structure 5; the connection between each second steel shot launching assembly 3025 and a first steel shot launching assembly 3022 via a channel 3026 ensures a relatively even probability and frequency of steel shot 3023 being delivered into each first steel shot launching assembly 3022, further guaranteeing the overall rust removal effect on the steel structure 5.

[0039] like Figure 3As shown, optionally, the drive mechanism 1 includes a slide rail 101, a rack 102 slidably mounted on the slide rail 101, a gear 103 meshing with the rack 102, a motor 104 connected to the gear 103, and multiple lifting components 105 mounted on the rack 102. It is understood that the slide rail 101 is fixed at a high point above the factory building or other work area; the rack 102 is provided with a slider, and the slide rail 101 has a corresponding groove, or the rack 102 has a groove, and the slide rail 101 has a corresponding slider; the motor 104 can be mounted on the slide rail 101 via a motor mount or other components, or mounted at a corresponding location in the factory building, and the output shaft of the motor 104 is connected to the gear 103; the lifting components 105 can be configured as hooks, connecting bolts, or buckles, etc., capable of engaging with... Figure 1 and Figure 2 The components used for connecting the slings. Specifically, such as... Figure 1 and Figure 3 As shown, when the motor 104 rotates, it drives the gear 103 to rotate, thereby driving the rack 102 to move, which in turn drives the shot blasting and rust removal mechanism 3 to move along the rust removal direction of the steel structure 5; the reciprocating motion of the shot blasting and rust removal mechanism 3 is achieved by changing the rotation direction of the motor 104.

[0040] In some embodiments, the drive mechanism 1 can also be implemented by a linear motor, a telescopic mechanism, a sprocket transmission mechanism or a belt transmission mechanism, as long as the operation of the mechanism can drive the shot blasting and rust removal mechanism to perform reciprocating motion.

[0041] like Figure 2 As shown, the sling 2 may include a chain lock and a lifting ring. One end of the chain lock is connected to the shot blasting and rust removal mechanism, and the other end is connected to the lifting ring. The lifting ring is connected to the lifting component 105 by means of hanging, bolting, or welding. The chain lock may also be replaced with a metal rope or a metal connecting column.

[0042] like Figure 1 and Figure 2 As shown, a connecting assembly 301 is provided at the end of each of the two rust-removing parts 302 away from the driving mechanism 1. Optionally, the connecting assembly includes protrusions 3011 respectively provided on the two rust-removing parts 302, and at least one connecting hole 3012 opened on the protrusion 3011; the protrusion 3011 can be understood as a structure such as an ear plate. After the receiving cavity 3021 on the two rust-removing parts 302 encloses the steel structure 5, the two rust-removing parts 302 are connected by bolts installed in the connecting hole 3012, avoiding the problem of the two rust-removing parts 302 separating during movement and improving the stability of the shot blasting rust removal mechanism 3.

[0043] like Figure 2 As shown, the rust removal section 302 can be a frame structure made of non-metallic plates, with the exterior being non-metallic plates and the interior being a cavity structure to accommodate the first shot launching assembly 3022, the shot recovery gap 3024, and the second shot launching assembly 2025, etc.; or the rust removal section 302 can be directly set as a solid structure, with mounting holes reserved in the solid structure for setting the first shot launching assembly 3022 and the second shot launching assembly 2025, as well as reserved for the shot recovery gap 3024 and the channel 3026, etc. The accommodating cavity 3021 can be arc-shaped or other shapes, as long as it can accommodate the steel structure 5.

[0044] The first steel shot launching assembly 3022 can be implemented using technology found in conventional steel shot launching devices. In some embodiments, such as Figure 4 As shown, to improve control flexibility, the first steel shot launching assembly 3022 may include a first launching cavity 30221, a first electromagnet 30222 disposed at the bottom of the first launching cavity 30221, a first spring 30223 disposed inside the first launching cavity 30221 and connected at one end to the first electromagnet 30222, a first magnet 30224 connected to the other end of the first spring 30223, a first controller 30225 connected to the first electromagnet 30222, and a first isolation layer 30226 disposed outside the first launching cavity 30221; optionally, the outer diameter of the first magnet 30224 is smaller than the inner diameter of the first launching cavity 30221, and the first isolation layer 30226 may be a structure made of rubber or similar materials. The design of 30226 avoids the influence of external metals or electromagnetic signals on the first electromagnet 30222. Specifically, when the first controller 30225 controls the first electromagnet 30222 to be energized, the first electromagnet 30222 attracts the first magnet piece 30224, the first spring 30223 is compressed, and the steel shot 3023 moves inward with the first spring 30223. When the first controller 30225 controls the first electromagnet 30222 to be de-energized, the compressed first magnet piece 30224 pops outward, launching the steel shot 3023. In order to reduce the influence of the attraction force of the first magnet piece 30224 on the steel shot 3023 on the launch, a non-metallic material isolation layer is provided at the contact surface between the first magnet piece 30224 and the steel shot 3023.

[0045] like Figure 2As shown, the steel shot recovery gap 3024 can be set in a circular chamber, a rectangular chamber, or a chamber of any other shape. In order to ensure that the steel shot 3023 enters the steel shot recovery gap 3024, the steel shot recovery gap 3024 can be set as an inclined gap, with the end of the steel shot recovery gap 3024 near the receiving cavity 3021 being higher than the end away from the receiving cavity 3021, so that the launched steel shot 3023 can smoothly enter the steel shot recovery gap 3024.

[0046] The second steel shot launching assembly 3025 can be implemented using technology found in conventional steel shot launching devices. In some embodiments, such as Figure 5 As shown, to improve control flexibility, the second steel shot launching assembly 3025 may include a second launching cavity 30521, a second electromagnet 30252 disposed at the bottom of the second launching cavity 30251, a second spring 30253 disposed inside the second launching cavity 30251 and connected at one end to the second electromagnet 30252, a second magnet 30254 connected to the other end of the second spring 30253, a second controller 30255 connected to the second electromagnet 30252, and a second isolation layer 30256 disposed outside the second launching cavity 30251; optionally, the outer diameter of the second magnet 30254 is smaller than the inner diameter of the second launching cavity 30251, and the second isolation layer 30256 may be a structure made of rubber or similar materials. The design of 30256 avoids the influence of external metals or electromagnetic signals on the second electromagnet 30252. Specifically, when the second controller 30255 controls the second electromagnet 30252 to be energized, the second electromagnet 30252 attracts the second magnet piece 30254, the second spring 30253 is compressed, and the steel shot 3023 moves inward with the second spring 30253. When the second controller 30255 controls the second electromagnet 30252 to be de-energized, the compressed second magnet piece 30254 pops outward, launching the steel shot 3023. In order to reduce the influence of the attraction force of the second magnet piece 30254 on the steel shot 3023 on the launch, a non-metallic material isolation layer is provided at the contact surface between the second magnet piece 30254 and the steel shot 3023.

[0047] like Figure 2 The channel 2026 is configured as an arc-shaped channel. By increasing the number of channels 2026, the impact of the steel shot 3023 launched by the second steel shot launching assembly 2025 on the first steel shot launching assembly 3022 is reduced. Furthermore, the arc shape of the channel 2026 allows for communication between multiple second steel shot launching assemblies 2025 and the first steel shot launching assembly 3022, avoiding interference between the multiple channels 2026. The hinge 303 can be implemented using a pin or similar method, which will not be detailed here.

[0048] like Figure 2 and Figure 6 At least one fan 304 is provided on one side of the rust removal section 302 to promptly and directionally blow the dust generated during rust removal out of the receiving cavity 3021, avoiding the problem of dust remaining in the receiving cavity 3021. Simultaneously, directional dust removal prevents the dust from spreading randomly and causing pollution to the outside environment. Directing the dust generated during rust removal out of the receiving cavity 3021 facilitates dust collection and avoids pollution. It is understood that after the two rust removal sections 302 are closed, there is a certain gap between the receiving cavity 3021 and the steel structure 5, which allows for the installation of the fan 304 and the flow and removal of dust. The fan 304 includes a fan cover 3041 and an impeller 3042, etc.

[0049] like Figure 2 When removing rust from the steel structure 5, the steel structure 5 can be placed under the drive mechanism with the help of the foundation 4; the steel structure 5 includes a single pile, tower, cage, pile stabilization platform or other wind turbine mechanism, etc.

[0050] Example 2:

[0051] This embodiment provides a shot blasting and rust removal device for steel structures in wind power project processing plants. The difference from the previous embodiment lies in the arrangement of the first steel shot launching assembly 3022 and the second steel shot launching assembly 3025. Optionally, in the first steel shot launching assembly 3022 and the second steel shot launching assembly 3025, the springs within the launching chambers utilize electromagnetic induction components to achieve extension and retraction, such as... Figure 7 As shown, the electromagnetic induction component includes a coil, a magnet, and a force-bearing rod. When the coil is connected to alternating current, it can reciprocate, driving the spring in the firing chamber of the first steel shot launching component 3022 or the second steel shot launching component 3025 to move, thereby driving the steel shot in the firing chamber to strike the steel structure 5.

[0052] Among them, Ampere force is:

[0053] F=BIL

[0054] Where B is the magnetic flux density; I is the current; and L is the effective length of the magnetic field lines cut.

[0055] B=K*I / R

[0056] Where K is a constant, and can be 6.674 * 10^63. -3 R is the distance from the current source.

[0057] The coil diameter is approximately 0.2m, using a common 220V voltage, and the length of the magnetic field lines cut is approximately 0.3m. From the above parameters, the maximum value of F is 79.46N; the spring force calculation formula is:

[0058] F=k*d

[0059] Where k is the spring constant; d is the distance the spring is compressed; the steel shot is ejected at a velocity of 30 m / s, which can achieve the purpose of rust removal; the acceleration is:

[0060] a=F / m

[0061] Where m is mass.

[0062] Therefore, it can be concluded that one set of elastic devices can simultaneously drive the movement of 300 vertical and horizontal spring devices.

[0063] Example 3:

[0064] This embodiment provides a shot blasting method for steel structures in wind power project processing plants. It employs the shot blasting device for steel structures in wind power project processing plants as described in Embodiment 1, comprising: two rust removal sections 302 combined to house the steel structure 5 within a receiving cavity 3021; ​​a first steel shot launching assembly 3022 launching steel shot 3023 to remove rust from the steel structure 5; after the steel shot 3023 launched by the first steel shot launching assembly 3022 has completed rust removal from the steel structure 5, it falls through a steel shot recovery gap 3024 into a second steel shot launching assembly 3025; the second steel shot launching assembly 3025 launches the recovered steel shot 3023, which then re-enters the first steel shot launching assembly 3022 through a channel 3026 for reuse.
