Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a vibrating screen for wear-resistant repair agents. Background Technology

[0002] Wear-resistant repair agents, as a key industrial material, are widely used for the repair and protection of worn parts in equipment. Their final performance is closely related to the particle size distribution and uniformity of the raw material powder. Therefore, in the production process of wear-resistant repair agents, using a vibrating machine to accurately sieve the mixed raw materials and remove unqualified coarse particles and impurities is one of the core processes to ensure product quality.

[0003] Currently, most vibrating screens used for powder screening on the market rely on a vibrating motor to generate a single excitation force, causing the screen to vibrate regularly at high frequencies, such as horizontal rotary motion or vertical reciprocating motion. This vibration method aims to make the material jump and spread on the screen surface through vibration, thus allowing particles smaller than the screen openings to pass through the screen and achieve material classification.

[0004] However, when handling materials with high density, irregular powder morphology, or potential stickiness, such as wear-resistant repair agents, the aforementioned single vibration mode often reveals its limitations. Simple planar rotation or up-and-down jumping is insufficient to achieve adequate loosening and stratification of the material layer, leading to material accumulation or clumping on the screen surface and resulting in low screening efficiency. More seriously, critical particles close to the screen aperture size are easily wedged into and clogged by the unidirectional vibration force. This clogging rapidly reduces the effective screening area and may even cause screening interruptions, requiring frequent shutdowns for manual cleaning, severely impacting production continuity and efficiency.

[0005] Therefore, this utility model proposes a vibrating sieve for wear-resistant repair agents to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of low screening efficiency, easy clogging of screens and easy wear of moving parts by material intrusion in the existing vibrating machine body for wear-resistant repair agents, the present invention aims to provide a vibrating machine body for wear-resistant repair agents with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a vibrating screen for wear-resistant repair agents, including a machine body, a drive motor, a drive rod, a screen, a fixed top plate, a spiral conveyor cylinder, a protective plate, a sliding block, a protective sleeve, and a corrugated chute.

[0008] The wavy chute is formed on the inner wall of the organism, and the wavy chute is a continuously undulating track.

[0009] Furthermore, the machine body, drive motor, drive rod, screen, fixed top plate, spiral conveyor cylinder, protective plate, sliding block, and protective sleeve are combined in the following way: the drive motor is fixedly connected to the top of the machine body, the drive rod is fixedly connected to the output end of the drive motor and extends vertically downward into the machine body, the screen is set inside the machine body, the center of the screen has a through hole that matches the cross-sectional shape of the drive rod, the fixed top plate is fixedly connected inside the machine body and located above the screen, the spiral conveyor cylinder is fixedly connected to the bottom surface of the fixed top plate and located below the screen, the inner wall of the spiral conveyor cylinder is a spiral inner wall, the protective plate is fixedly connected to the bottom surface of the screen, the sliding block is fixedly connected to the outer wall of the protective plate and is evenly distributed along the circumference of the outer wall of the protective plate, the sliding block is slidably set in the corrugated groove, and the protective sleeve is sleeved on the outer wall of the drive rod, the upper end of the protective sleeve is connected to the fixed top plate, and the lower end is connected to the center of the screen.

[0010] Preferably, the vibrating machine body for the wear-resistant repair agent further includes a connecting cylinder and a feeding cylinder. The connecting cylinder is fixedly connected to the top surface of the fixed top plate and communicates with the internal space of the connecting cylinder. The feeding cylinder is connected to and fixed to the outer wall of the connecting cylinder and extends outward through the side wall of the machine body to facilitate the introduction of the material to be screened into the equipment.

[0011] Preferably, the vibrating machine body for the wear-resistant repair agent further includes a discharge cylinder, which is connected and fixed to the outer wall of the machine body, and the feed end of the discharge cylinder corresponds to the discharge end of the screw conveyor cylinder to receive the screen material conveyed by the screw conveyor cylinder.

[0013] Preferably, the protective plate is a ring-shaped plate structure, which has good structural stability and dynamic balance characteristics. The sliding blocks are evenly distributed along the outer circumference of the protective plate, ensuring uniform force during high-speed rotation and making the shaking of the screen more stable.

[0014] Preferably, the inner wall of the spiral conveyor cylinder is a spiral-shaped inner wall. This fixed spiral-shaped inner wall forms a relative motion with the rotating screen, thereby generating a continuous radial outward thrust on the material on the screen, achieving effective material conveying.

[0015] Preferably, the drive rod and the screen are slidably inserted. Specifically, the non-circular cross section of the drive rod matches the fitting through hole in the center of the screen, which can reliably transmit torque and ensure that the screen can slide freely along the axial direction of the drive rod without obstruction when it vibrates.

The technical effect of automatically and continuously conveying and discharging the material on the screen to the outer edge by utilizing the relative motion between the screen and the spiral conveyor is achieved, simplifying the equipment structure and realizing continuous operation.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 4This utility model provides a vibrating screen for wear-resistant repair agents, which aims to solve the problems of low screening efficiency, easy clogging of the screening screen, and easy wear of moving parts by material intrusion in the prior art.

[0022] like Figure 1 and Figure 2 As shown, the vibrating screen for wear-resistant repair agent includes a body 1, which serves as the mounting base and housing for the entire device. A drive motor 3 is fixedly connected to the top of the body 1 and provides rotational power for the entire device.

[0023] The drive rod 207 is fixedly connected to the output end of the drive motor 3 and extends vertically downward into the interior of the machine body 1. The screen 202 is set inside the machine body 1. The center of the screen 202 has a through hole that matches the cross-sectional shape of the drive rod 207. This structure allows the screen 202 to rotate synchronously with the drive rod 207 and slide along the axial direction of the drive rod 207. The screen 202 is used to screen the material entering the machine body 1.

[0024] The fixed top plate 2 is fixedly connected to the inside of the machine body 1 and is located above the screen 202. The spiral conveyor cylinder 201 is fixedly connected to the bottom surface of the fixed top plate 2 and the screen 202 is located below the spiral conveyor cylinder 201. The inner wall of the spiral conveyor cylinder 201 is a spiral inner wall. This structure is used to radially convey and guide the material on the screen located on the top surface of the screen 202 when the screen 202 rotates.

[0025] To solve the above technical problems, a wave-shaped groove 208 is provided on the inner wall of the machine body 1, and a sliding block 204 that rotates together with the screen 202 slides in it, thereby converting the rotational motion into a compound rotational vibration. At the same time, the motion mechanism is isolated and protected by the protective plate 203 and the protective sleeve 206.

[0026] Please refer to the following carefully. Figure 2 and Figure 3 The inner wall of the machine body 1 is provided with a wave-shaped groove 208 extending along its circumference. The groove 208 is a continuously undulating track, which provides a fixed motion trajectory for the subsequent axial vibration of the screen 202.

[0027] The protective plate 203 is fixedly connected to the bottom surface of the screen 202. The protective plate 203 is an annular plate. The sliding block 204 is fixedly connected to the outer wall of the protective plate 203 and is evenly distributed along the circumference of the outer wall of the protective plate 203. In the assembled state, the sliding block 204 is slidably set in the slide groove 208. This structure causes the sliding block 204 fixed to the screen 202 to move along the trajectory of the fixed wave-shaped slide groove 208 when the drive motor 3 drives the screen 202 to rotate. This causes the screen 202 to generate high-frequency axial reciprocating vibration while rotating, thereby achieving efficient screening of materials.

[0028] In addition, as the protective plate 203 rotates with the screen 202, its body circumferentially blocks the opening of the slide groove 208 to prevent the screened material from falling into the slide groove 208 and avoids interference or wear on the sliding block 204. The protective sleeve 206 is fitted on the outer wall of the drive rod 207, and the upper end of the protective sleeve 206 is connected to the fixed top plate 2, and the lower end is connected to the center of the screen 202. The protective sleeve 206 is used to isolate the drive rod 207 from the material in the screening chamber, prevent dust from entering the sliding fit gap between the drive rod 207 and the screen 202, and ensure the long-term stable operation of the device.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, in order to facilitate the introduction of the material to be screened into the equipment, a connecting cylinder 205 and a feeding cylinder 4 are also included. The connecting cylinder 205 is fixedly connected to the top surface of the fixed top plate 2 and communicates with its internal space. The feeding cylinder 4 is connected to and fixed to the outer wall of the connecting cylinder 205 and extends outward through the side wall of the machine body 1.

[0030] As another preferred embodiment, in order to discharge the material remaining on the screen 202 after screening, a discharge cylinder 401 is also included. The discharge cylinder 401 is connected and fixed to the outer wall of the machine body 1, and the feed end of the discharge cylinder 401 corresponds to the discharge end of the screw conveyor cylinder 201 to receive the material conveyed by the screw conveyor cylinder 201.

[0031] As another preferred embodiment, in order to discharge the fine material after it has been screened by the screen 202, a discharge port 402 is provided on the bottom surface of the machine body 1.

[0032] As a further optimization of the vibration mechanism, the protective plate 203 is preferably an annular plate structure. This structure has good structural stability and dynamic balance characteristics. The sliding block 204 is evenly distributed along the outer circumference of the protective plate 203, ensuring uniform force during high-speed rotation, making the shaking of the screen 202 more stable.

[0033] As a further explanation of the material conveying mechanism, the inner wall of the spiral conveyor cylinder 201 is a spiral inner wall. This fixed spiral inner wall forms a relative motion with the rotating screen 202, thereby generating a continuous radial outward thrust on the material on the screen 202.

[0034] As a further explanation of the transmission mechanism, the drive rod 207 and the screen 202 are slidably inserted. Specifically, the non-circular cross section of the drive rod 207 matches the fitting through hole in the center of the screen 202, which can reliably transmit torque and ensure that the screen 202 can slide freely along the axial direction of the drive rod 207 without obstruction when it vibrates.

[0035] Working principle: When the repair agent raw material needs to be screened, the raw material is input from the feed cylinder 4, falls into the interior of the screw conveyor cylinder 201 through the connecting cylinder 205, and is evenly distributed on the top surface of the screen 202.

[0036] At this time, the drive motor 3 is started, and the drive motor 3 drives the drive rod 207 to rotate at high speed. Since the drive rod 207 and the through hole in the center of the screen 202 are slidably inserted, the screen 202 rotates synchronously with the drive rod 207. While the screen 202 is rotating, the sliding block 204 fixed at its bottom also rotates and is forced to slide in the wave-shaped groove 208 fixed on the inner wall of the machine body 1. Since the trajectory of the groove 208 is up and down, the sliding block 204 drives the entire screen 202 to vibrate up and down at high frequency along the axial direction of the drive rod 207, thereby realizing the compound motion of rotation and vibration, which greatly improves the screening efficiency.

[0037] While the screen 202 rotates and vibrates, the spiral conveyor cylinder 201 above it remains stationary. As the screen 202 rotates, the material on it is guided and pushed by the fixed inner wall of the spiral conveyor cylinder 201, and is continuously conveyed radially outward. Finally, the oversize material with a size larger than the aperture of the screen 202 is conveyed to the discharge cylinder 401 and discharged, while the undersize material with a size smaller than the aperture of the screen 202 passes through the screen 202, falls into the lower part of the machine body 1, and is discharged from the discharge port 402.

[0038] Throughout the entire operation, the protective plate 203 rotates and blocks the slide 208 to prevent material from entering and causing the sliding block 204 to jam. At the same time, the protective sleeve 206 always isolates the drive rod 207 from the material to prevent dust from entering the sliding fit gap, thus ensuring the reliability and durability of the equipment operation.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
