Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to a shot blasting cleaning equipment for steel structures. Background Technology

[0002] Shot blasting is a surface treatment process that uses a high-speed rotating impeller of a shot blasting machine to throw shot, such as steel shot or cast iron shot, at high speed to impact and grind the surface of steel structure workpieces, so as to clean surface impurities and enhance the performance of workpieces.

[0003] In traditional steel shot blasting machines, the high-speed impact of steel shot into the workpiece generates fine fragments that do not meet grinding requirements due to wear and impact. Simultaneously, rust, dust, and other impurities detached from the workpiece surface mix thoroughly with the steel shot. Lacking an effective screening and recovery structure, traditional steel shot blasting machines cannot separate intact steel shot from impurities in the mixture, discharging the entire mixture as waste. This results in a significant amount of qualified steel shot, still possessing grinding properties, being discarded along with the impurities, leading to direct waste. Furthermore, to maintain shot blasting effectiveness, companies must continuously purchase new steel shot, further increasing the total consumption and exacerbating the waste problem. Therefore, we provide a steel structure shot blasting cleaning equipment. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model relates to a steel structure shot blasting cleaning device, including a support frame 1; a shot blasting machine body 2 is mounted on the upper surface of the support frame 1; two support plates 3 are symmetrically fixed on the inner side of the support frame 1; a screening assembly 4 is slidably arranged on the upper surface of the two support plates 3; the screening assembly 4 includes a vertical plate 401 fixed to the outer wall of the support frame 1 and a frame plate 407 sliding on the upper surface of the two support plates 3; an L-shaped rod 404 is also fixedly connected to the outer wall of the support frame 1; a sliding rod 405 connected to the frame plate 407 is slidably connected to the inner side of the L-shaped rod 404. The inner wall of the frame plate 407 is rotatably connected to the adjacent sides of the frame plate 409. The screen 408 is fixedly connected between the two screens 409. The outer wall of the vertical plate 401 is rotatably provided with an eccentric wheel 402. The outer wall of the vertical plate 401 is fixedly connected to a motor 406. The output end of the motor 406 is fixedly connected to the middle of the eccentric wheel 402. The outer wall of the eccentric wheel 402 is rotatably connected to a connecting rod 403. The connecting rod 403 is rotatably connected to a sliding rod 405. The inner wall of the frame plate 407 is fixedly connected to a tilting component 5 that works with the screen 408.

[0023] Support frame 1 serves as the basic framework of the equipment, supporting all components such as the shot blasting machine body 2 and screening assembly 4, ensuring overall structural stability. Connecting to an external power source starts motor 406, which is mounted on the vertical plate 401. Motor 406 is controlled to rotate forward and backward by a PLC microcontroller. The rotation of motor 406 drives the eccentric wheel 402 to rotate. The rotation center of the eccentric wheel 402 is not coaxial with the output shaft of motor 406. The rotation of the eccentric wheel 402 drives connecting rod 403 to push sliding rod 405 in an L-shape. The inner side of rod 404 slides back and forth; the slide rod 405 is connected to the frame plate 407, so the frame plate 407 moves back and forth with the slide rod 405 on the support plate 3, causing the screen 408 to move in a straight line. When the shot blasting machine body 2 is working, the shot mixture, such as steel shot and impurity debris, falls onto the screen 408. Through the reciprocating vibration of the screen 408, smaller diameter impurities, such as rust debris and broken steel shot, fall through the holes of the screen 408, while complete steel shot of the correct diameter remains on the surface of the screen 408, thus achieving separation.

[0024] Please see Figures 2-5 The tilting assembly 5 includes a U-shaped plate 501, a worm gear 502 is rotatably arranged on the inner side of the U-shaped plate 501, a motor 504 is fixedly connected to the outer wall of the U-shaped plate 501, the output end of the motor 504 is fixedly connected to the end of the worm gear 502, and a worm wheel 503 fixed to the outer wall of one of the rotating shafts 409 is meshed with the outer wall of the worm gear 502.

[0025] When a certain amount of qualified steel shot accumulates on the surface of screen 408, an external power source is connected, and motor 504, fixed on U-shaped plate 501, is started. Motor 504 drives worm 502 to rotate. Worm 502 meshes with worm wheel 503 fixed on rotating shaft 409, transmitting the rotational motion to rotating shaft 409. Rotating shaft 409 drives screen 408 to flip. The tilt angle of screen 408 can be controlled by starting and stopping motor 504, which is controlled by PLC microcontroller. Qualified steel shot on screen 408 is poured into the designated recycling area, completing the recycling and reuse of steel shot.

[0026] Please see Figure 2 Two slide rails 7 are symmetrically fixed on the inner side of the support frame 1, and a collection box 6 that works with the screen 408 is slidably connected inside the two slide rails 7.

[0027] The fine impurities separated by the screen 408 fall through the holes of the screen 408 and into the collection box 6 below. The collection box 6 is slidably connected in the slide rail 7. When the impurities accumulate to a certain amount, the collection box 6 can be pulled out along the slide rail 7 to empty the impurities. Then the collection box 6 will collect the steel shot on the screen 408.

[0028] The operation process of this embodiment is as follows: The support frame 1 serves as the basic frame of the equipment, supporting all components such as the shot blasting machine body 2 and the screening assembly 4, ensuring the overall structural stability. An external power supply is connected to start the motor 406 mounted on the vertical plate 401. The motor 406 is controlled to rotate forward and backward by a PLC microcontroller. The rotation of the motor 406 drives the eccentric wheel 402 to rotate. The rotation center of the eccentric wheel 402 is not coaxial with the output shaft of the motor 406. The rotation of the eccentric wheel 402 drives the connecting rod 403 to push the slide rod 405 to slide back and forth inside the L-shaped rod 404. The slide rod 405 is connected to the frame plate 407, so the frame plate 407, along with the slide rod 405, moves the screen 408 in a reciprocating linear motion on the support plate 3. The shot mixture generated when the shot blasting machine body 2 is working, such as steel shot and impurities, falls onto the screen. On screen 408, through the reciprocating vibration of screen 408, smaller impurities, such as rust fragments and broken steel shot, fall through the holes of screen 408, while complete steel shot of the correct diameter remains on the surface of screen 408, achieving separation. When a certain amount of qualified steel shot accumulates on the surface of screen 408, an external power source is connected, and motor 504 fixed on U-shaped plate 501 is started. Motor 504 drives worm gear 502 to rotate. Worm gear 502 meshes with worm wheel 503 fixed on rotating shaft 409, transmitting the rotational motion to rotating shaft 409. Rotating shaft 409 drives screen 408 to rotate. The tilt angle of screen 408 can be controlled by starting and stopping motor 504, which is controlled by a PLC microcontroller. The qualified steel shot on screen 408 is poured into the designated recycling area, completing the recycling and reuse of steel shot.
