Description

Technical Field

[0001] This invention relates to the field of sludge removal technology, specifically a gravity-type scraper for removing sludge. Background Technology

[0002] A scraper is a tool primarily used to clean the surface of steel strips or alignment rollers. During metal processing, the surface of steel strips or alignment rollers may become contaminated with impurities such as oil, iron filings, and dust. These impurities not only affect production efficiency but can also lead to product quality problems. To ensure production quality and improve efficiency, scrapers are widely used in the metal processing industry. A well-designed scraper can better conform to the surface of the steel strip or alignment roller, ensuring effective cleaning.

[0003] In existing technologies, self-weight scrapers are generally used. By using counterweights, the scraper is brought as close as possible to the steel strip or the straightening roller to improve the cleaning effect of the scraper. However, this approach has drawbacks. For example, when the steel strip is rolled at both ends of the mill, it will be wavy, and the ends of the steel strip and the middle of the steel strip will not be on the same plane. In this case, the self-weight scraper will not only fail to achieve the degreasing effect, but may also cause the steel strip to break. Summary of the Invention

[0004] The purpose of this invention is to provide a self-weight scraper for cleaning sludge. This technical solution enables the scraper to better fit with the steel belt or the straightening roller, thereby ensuring the cleaning effect of impurities.

[0005] To achieve the above objectives, the present invention provides a basic solution comprising: a long shaft, wherein a plurality of clamping bodies are provided in the middle of the long shaft, the clamping bodies being used to fix and clamp the blades, each clamping body being provided with a blade, and a telescopic device being provided between the clamping body and the blades for adjusting the relative position between the clamping body and the blades; and self-weighting devices are provided at both ends of the long shaft, the self-weighting devices comprising suspension rods and counterweights, the suspension rods being perpendicular to the long shaft and connected to the long shaft, and the counterweights being detachably connected to the ends of the suspension rods by nuts.

[0006] The beneficial effects of this basic design are that it incorporates several clamping bodies along the long shaft. If any clamping body or blade is damaged, it can be replaced selectively, facilitating maintenance and reducing costs. Based on this design, when processing irregular impurities, each clamping body can form a different angle, allowing each clamping body to better conform to the steel belt or straightening roller, ensuring effective cleaning of oil and other impurities. Simultaneously, self-weighting devices are installed at both ends of the long shaft. These devices utilize gravity to generate a downward force, thereby driving the clamping bodies and ensuring the blade adheres tightly to the surface of the steel belt, guaranteeing effective cleaning.

[0007] As a preferred implementation, the clamp body is slidably connected to the long shaft and fixed by screws.

[0008] As a preferred implementation, bearing housing supports are provided at both ends of the long shaft, and bearings connect the long shaft to the bearing housing supports.

[0009] As a preferred implementation, rotating operating levers are also provided at both ends of the long shaft, and the rotating operating levers are fixedly connected to the long shaft, with the rotating operating levers perpendicular to the long shaft.

[0010] As a preferred embodiment, the end of the clamping body is provided with a blade cleaning device, which can clean impurities on the blade as the blade moves.

[0011] As a preferred implementation, a receiving groove is fixedly connected above the clamping body to collect impurities on the blade.

[0012] As a preferred implementation, it also includes an angle control device, wherein the clamp body is rotatably connected to the long shaft, and the angle control device is used to control the angle of the clamp body. Attached Figure Description

[0016] The technical solution of this application will be further described in detail below through specific embodiments:

[0018] In the description of this invention, it should be noted that the terms "upper," "lower," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0019] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integrated connection; they can refer to a mechanical connection (including various forms of mechanical connection, such as couplings or gear pairs) or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] Reference Figure 1 A self-weight scraper for cleaning oil stains on the surface of steel strip includes: a bearing seat bracket 100, a clamping body 300, a long shaft 200, a self-weight device 201, a rotating operating rod 202, a receiving groove 301, a blade 400, and a blade cleaning device.

[0021] The bearing housing bracket 100 is mainly used to support the entire scraper. The bearing housing bracket 100 preferably has a triangular cross section to ensure that the scraper remains stable during operation. A bearing 101 is provided at the top of the bearing housing bracket 100.

[0022] The bearing housing bracket 100 is respectively provided at both ends of the long shaft 200, and the long shaft 200 and the bearing housing bracket 100 are connected by bearings. Several clamping bodies 300 are provided in the middle of the long shaft 200. The clamping bodies 300 are slidably connected to the long shaft 200, and can slide on the long shaft 200 and are fixed by screws.

[0023] The clamping body 300 is used to fix and clamp the blade 400. Each clamping body 300 is equipped with a blade 400, and the tightness of the clamping body 300 can be adjusted through the threaded hole. A telescopic device 401 is provided between the clamping body 300 and the blade 400. Preferably, an air bag is used as the power source to control the extension and retraction of the blade 400 and adjust the relative position between the clamping body 300 and the blade 400, ensuring that the blade 400 can adapt to different sizes of straightening rollers or steel belts and can always be in contact with the roller surface or steel belt.

[0024] The long shaft 200 has self-weighting devices 201 at both ends. Each self-weighting device 201 includes a suspension rod and a counterweight. The suspension rod is perpendicular to and connected to the long shaft, and the counterweight is detachably connected to the end of the suspension rod via a nut. The self-weighting device 201 utilizes gravity to generate a downward force, thereby driving the clamping body 300 and ensuring that the blade 400 fits tightly against the surface of the steel strip. This design makes the movement of the blade 400 on the steel strip surface more stable, improving cutting effect and efficiency.

[0025] The scraper blade is positioned opposite to the direction of the steel belt. The scraper is pressed against the surface of the steel belt by the weight device 201. The telescopic device 401 adjusts the fit between the blade 400 and the steel belt. The scraper blade scrapes off sludge or impurities that fall into the receiving trough 301. The impurities and sludge are then poured out through the receiving trough 301. At the same time, when the receiving trough 301 is withdrawn, the blade cleaning device cleans the residual sludge and impurities from the blade blade into the receiving trough 301.

[0026] The end of the clamping body 300 is equipped with a blade 400 cleaning device, which can clean impurities and oil stains on the blade 400 as the blade 400 moves. A receiving groove 301 is fixedly connected to the top of the clamping body 300 to collect residual oil sludge and other impurities from the blade 400.

[0027] In this embodiment, since the steel strip is brittle, the blade 400 is preferably made of rubber or wood.

[0028] The long shaft 200 is also provided with a rotating operating rod 202 at both ends. The rotating operating rod 202 is fixedly connected to the long shaft 200. The rotating operating rod 202 is perpendicular to the long shaft 200. Preferably, the rotating operating rod 202 is at a right angle to the counterweight rod. The rotating operating rod 202 can be used to rotate the long shaft 200, thereby driving the blade 400 away from the steel strip and adjusting the receiving groove 301, which is convenient for changing the blade and emptying the waste material.

[0029] In practical use, when the steel belt or the straightening roller is running, the direction of the scraper blade is opposite to the running direction of the steel belt or the straightening roller. The scraper is pressed against the surface of the steel belt by the self-weight device 201, and the blade scrapes off the sludge or impurities that fall into the receiving trough 301.

[0030] Impurities and sludge are extracted and poured out through the receiving trough 301. At the same time, when the receiving trough 301 is extracted, the blade cleaning device cleans the residual sludge and impurities on the blade into the receiving trough 301.

[0031] Example 2

[0032] The technical feature that distinguishes this embodiment from Embodiment 2 is that the clamping body 300 is rotatably connected to the long shaft 200. When the blade 400 is subjected to the reaction force under different deformations of the steel strip, several clamping bodies 300 will form different angles to adapt to different deformations of the steel strip, thereby more effectively avoiding steel strip breakage.

[0033] At this point, it is necessary to ensure that the clamp body 300 does not slide on the long shaft 200 during operation. One possible implementation is to limit the overall position of the clamp bodies 300 by fixing the clamp bodies 300 at both ends with screws.

[0034] At this point, the self-weight device 201 is mainly used to ensure the stability of the scraper as a whole and the long shaft 200, but it cannot guarantee that the blade 400 will always be in contact with the surface of the steel strip. (Refer to...) Figure 2 This embodiment also includes a controller, a friction sensor, an angle sensor, and an angle control device. The controller is electrically connected to the friction sensor, the angle sensor, and the angle control device. The friction sensor is used to monitor the friction force of the straightening roller or steel belt on the blade 400. The angle sensor is used to monitor the angle control device. The angle control device is used to apply a force to the groove surface of the drawer-type receiving groove 301 to adjust the angle of the clamping body 300 so that the blade 400 fits better with the steel belt while avoiding the steel belt from breaking.

[0035] The controller calculates and analyzes the force applied by the angle control device in real time. The calculation formula is as follows:

[0036]

[0037] In the formula, The magnitude of the force applied to the surface of the drawer-type receiving trough by the angle control device. Let be the distance from the point of application of the force of the angle control device to the center of the major axis circle. This is the distance from the cutting edge to the center of the major axis. Its size can be adjusted by a telescopic device. The angle between the surface of the drawer-type material receiving tray and the horizontal direction. The coefficient of friction, This is friction.

[0038] The controller obtains this information based on calculation and analysis. The size sends a control signal to the angle control device, thereby adjusting the angle of different clamping bodies.

[0039] This disclosure also provides a scraper angle control method, which utilizes a gravity-type scraper for cleaning sludge as described in the above embodiments.

[0040] This disclosure also provides a storage medium storing a computer program that, when executed by a processor, can implement all the steps of a scraper angle control method.
