Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of steel shot recycling and processing, specifically to a steel shot recycling anti-clogging screening vibrator for casting production lines. Background Technology

[0002] In casting production lines, steel shot is a core consumable for cleaning the surface of castings (such as removing oxide scale and adhering sand). Recycling and reusing steel shot can significantly reduce production costs and resource waste, and the cleanliness of the recycling process directly determines the effectiveness of the steel shot in subsequent uses. As casting production moves towards higher efficiency and environmental protection, the shortcomings of traditional steel shot recycling equipment are becoming increasingly apparent: existing steel shot recycling relies heavily on simple screening devices (such as ordinary vibrating screens) and lacks targeted dust treatment structures. During recycling, a large amount of dust mixed in the steel shot cannot be fully removed, which not only affects the reusability of the steel shot but also causes a series of production problems.

[0003] In traditional recycling processes, friction between steel shot and castings, along with its own wear, generates metal dust and sand particles from casting. This dust enters the recycling equipment along with the steel shot. Because the equipment lacks effective dust control, the dust adheres to the surface of the steel shot or gets trapped between its particles. During subsequent use, the dust-laden steel shot reduces the precision of casting cleaning, and dust particles may scratch the casting surface under the impact of the steel shot, affecting product appearance and quality. Furthermore, untreated dust easily accumulates in the screen holes and conveying pipes of the recycling equipment, causing blockages and requiring frequent shutdowns for disassembly and cleaning, disrupting production line continuity and increasing labor and maintenance costs.

[0004] Therefore, developing a steel shot recycling anti-clogging screening vibrator for casting production lines that can fully handle dust in steel shot recycling while avoiding equipment blockage has become an urgent need to optimize the casting production process and ensure the quality of steel shot reuse. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a steel shot recovery anti-clogging screening vibrator for casting production lines, which solves the technical problem that existing steel shot recovery methods mostly rely on simple screening devices, lack targeted dust treatment structures, and cannot fully remove a large amount of dust mixed in the steel shot during recovery.

[0006] According to one aspect, at least one embodiment of this disclosure provides a shot recovery anti-clogging screening vibrator for a casting production line, comprising: A recycling bin and an inner partition, wherein the inner partition is disposed inside the recycling bin; A vibrating screening assembly is disposed in the recycling bin; A collection and discharge assembly is disposed at the bottom of the recycling bin; The vibrating screening assembly includes a swing plate, which is rotatably connected to the recycling bin via a rotating shaft. The connection point of the swing plate is located directly above the inner partition. A rectangular groove is formed on the surface of the swing plate, and several circular openings are formed in the rectangular groove. A screen plate is set inside the rectangular groove.

[0007] As a further technical solution, the bottom surface of the sieve plate is provided with several connecting frames, all of which are located inside the circular opening. A buffer spring is fitted on the connecting frame, and the buffer spring is located on the back of the swing plate.

[0008] As a further technical solution, the rectangular groove is provided with several slag discharge ports, one end of the rotating shaft of the swing plate is provided with a worm gear, the side surface of the recycling box is provided with a drive motor, the output end of the drive motor is provided with a worm, and the worm meshes with the worm gear.

[0009] As a further technical solution, a horizontal plate is provided on one of the horizontally distributed connecting frames, and a vibration motor is installed at both ends of the surface of the horizontal plate. A cover is provided on the side surface of the inner partition, and the cover corresponds to the position of the vibration motor.

[0010] According to another aspect, in at least one embodiment of the present invention, the collection and discharge assembly includes a central hood, which is disposed on one side of the bottom of the recycling bin, and a bottom box is disposed at the bottom of the central hood, in which a conveying auger is installed.

[0011] As a further technical solution, a blocking cover is provided on the upper surface of the swing plate, and an outlet is provided on the surface of the blocking cover.

[0012] As a further technical solution, the bottom of the recycling bin is provided with a cleaning port, and the bottom of the recycling bin is provided with a sliding cover, which is located below the cleaning port.

[0013] As a further technical solution, the swing plate can be rotated 180° by the transmission of the worm gear and the worm wheel.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: This disclosure addresses the problems of incomplete dust removal and easy clogging in traditional screening methods by using a vibrating screening component. A vibrating motor provides high-frequency power, driving the screen plate to vibrate continuously. This quickly removes metal debris and sand dust from the surface of the steel shot. Combined with the precise aperture of the screen plate, efficient separation of dust and steel shot is achieved, preventing dust from adhering to the steel shot and affecting the subsequent casting cleaning accuracy. The buffer springs absorb vibration impact, protecting the swing plate and recovery box structure, while also allowing the screen plate to maintain a small, adaptive vibration, preventing steel shot from getting stuck in the screen holes and reducing the risk of clogging.

[0015] The rectangular trough's discharge port guides dust downwards, preventing dust from spreading and polluting the environment. The shroud effectively blocks dust from entering the vibrating motor, extending its lifespan. The worm gear-driven swing plate can rotate flexibly, allowing for rapid discharge after screening and preventing steel shot from accumulating on the screen surface. This overall structure significantly improves the steel shot dust removal rate, ensuring the purity of reused steel shot and reducing defects such as surface scratches and incomplete cleaning of castings caused by dust.

[0024] like Figures 1-4 As shown, it illustrates a shot recycling anti-clogging screening vibrator for a casting production line according to an embodiment of this disclosure, comprising: The recycling bin 1 and the inner partition 2 are disposed inside the recycling bin 1; Vibrating screening assembly 3, wherein the vibrating screening assembly is disposed in the recycling bin 1; Collection and discharge assembly 4 is disposed at the bottom of the recycling bin 1; The vibrating screening assembly 3 includes a swing plate 3-1, which is rotatably connected to the recycling bin 1 via a rotating shaft. The connection point of the swing plate 3-1 is located directly above the inner partition 2. A rectangular groove 3-2 is formed on the surface of the swing plate 3-1, and several circular openings 3-3 are formed within the rectangular groove 3-2. A screen plate 3-4 is arranged within the rectangular groove 3-2, and several connecting frames 3-5 are arranged on the bottom surface of the screen plate 3-4. The connecting frames 3-5 are all located within the circular openings 3-3, and buffer springs 3-6 are fitted on the connecting frames 3-5. The buffer springs 3-6 are located on the swing plate 3-1. -1 On the back side, the rectangular groove 3-2 has several slag discharge ports 3-7. One end of the rotating shaft of the swing plate 3-1 is provided with a worm gear 3-8. The side surface of the recycling box 1 is provided with a drive motor 3-9. The output end of the drive motor 3-9 is provided with a worm 3-10. The worm 3-10 meshes with the worm gear 3-8. A horizontal plate 3-11 is provided on a row of horizontally distributed connecting frames 3-5. Vibration motors 3-12 are installed at both ends of the surface of the horizontal plate 3-11. A cover 3-13 is provided on the side surface of the inner partition 2. The cover 3-13 corresponds to the position of the vibration motor 3-12.

[0025] In some examples, to achieve efficient removal of dust from the surface of steel shot and smooth discharge of steel shot, and to avoid the problems of dust residue or poor discharge caused by insufficient vibration in traditional screening, a vibrating screening component 3 is designed. This component includes a swing plate 3-1 rotatably connected to the recycling box 1 via a rotating shaft. The connection point is located directly above the inner partition 2, forming the core rotating structure for screening and discharge. The rectangular groove 3-2 on the surface of the swing plate 3-1 provides an installation reference for the screen plate 3-4. Several connecting frames 3-5 on the bottom surface of the screen plate 3-4 are inserted into the circular openings 3-3 of the rectangular groove 3-2, so that the screen plate 3-4 and the swing plate 3-1 form a buffered connection. The buffer spring 3-6 fitted on the connecting frame 3-5 is located on the back of the swing plate 3-1. When the screen plate 3-4 is vibrated, the buffer spring 3-6 can absorb the vibration impact, which not only avoids the vibration being directly transmitted to the swing plate 3-1 and causing structural wear, but also allows the screen plate 3-4 to maintain a small-amplitude high-frequency vibration, thus improving the dust screening effect.

[0026] The sieve plate 3-4 serves as the core of the screening process. Its aperture is adapted to the size of the steel shot, ensuring that the steel shot remains on the surface of the sieve plate 3-4 and the dust falls through the sieve holes. Several slag discharge ports 3-7 in the rectangular groove 3-2 provide discharge channels for the falling dust. The dust falls into the slag collection area at the bottom of the recovery box 1 through the slag discharge ports 3-7, achieving efficient separation of steel shot and dust.

[0027] The worm gear 3-8 at one end of the rotating shaft of the swing plate 3-1 meshes with the worm 3-10 at the output end of the drive motor 3-9 on the side surface of the recycling box 1, forming the flipping drive mechanism of the swing plate 3-1. When the drive motor 3-9 is running, the worm 3-10 drives the worm gear 3-8 and the rotating shaft to rotate, thereby driving the swing plate 3-1 to flip around the rotating shaft. During the screening stage, the swing plate 3-1 remains in a horizontal state to ensure that the screen plate 3-4 fully receives the steel shot. After screening, the swing plate 3-1 flips to an inclined state, and the steel shot slides out along the inclined screen plate 3-4 to the collection and discharge assembly 4 to achieve directional discharge.

[0028] The horizontal plate 3-11 is fixed on a row of horizontal connecting frames 3-5. The vibrating motors 3-12 at both ends of its surface provide the core power for screening. When the vibrating motors 3-12 are running, they drive the horizontal plate 3-11 and the connecting frames 3-5 to vibrate, which in turn drives the screen plate 3-4 to vibrate at high frequency, accelerating the removal of dust from the surface of the steel shot and allowing it to fall through the screen holes. The vibration direction of the vibrating motors 3-12 is perpendicular to the surface of the screen plate 3-4, maximizing the dust screening efficiency. The shrouds 3-13 on the two sides of the inner partition plate correspond to the positions of the vibrating motors 3-12, which can prevent the dust raised during the screening process from entering the interior of the vibrating motors 3-12, avoiding dust from affecting the motor's operating accuracy or causing motor failure, and extending the motor's service life.

[0029] With the coordinated operation of all components, the vibration provided by the vibrating motor 3-12 and the adaptive cooperation of the buffer spring 3-6 ensure thorough screening, while the flipping structure driven by the worm gear 3-8 and worm 3-10 ensures smooth discharge and effectively prevents steel shot from accumulating and clogging.

[0030] like Figures 1-4 As shown in the figure, the collection and discharge assembly 4 in this embodiment includes a central cover 4-1, which is disposed on one side of the bottom of the recycling box 1. A bottom box 4-2 is disposed at the bottom of the central cover 4-1, and a conveying auger 4-3 is installed in the bottom box 4-2.

[0031] In some examples, in order to achieve efficient reception and anti-clogging discharge of the screened steel shot and avoid the discharge blockage problem caused by steel shot accumulation in traditional collection, a collection and discharge component 4 is designed. This component includes a collection hood 4-1 set on one side of the bottom of the recovery box 1, which has a funnel-shaped structure. Its upper opening is precisely aligned with the discharge path of the vibrating screening component 3. When the swing plate 3-1 flips to discharge the steel shot, the steel shot can slide directly into the collection hood 4-1 along the inclined screen plate 3-4. The funnel-shaped structure can guide the steel shot to converge towards the center, avoiding the steel shot from scattering to other areas at the bottom of the recovery box 1 and causing incomplete collection. The inner wall of the collection hood 4-1 needs to be smoothed to reduce the frictional resistance when the steel shot slides down and prevent the steel shot from accumulating and clogging on the inner wall of the collection hood 4-1.

[0032] The bottom of the collection hood 4-1 is fixedly connected to the bottom box 4-2, forming a transitional receiving space for steel shot. The conveying auger 4-3 installed inside the bottom box 4-2 provides the core power for steel shot discharge. The conveying auger 4-3 is driven by electricity to rotate, and its blades are tightly fitted with the inner wall of the bottom box 4-2. When the steel shot falls from the collection hood 4-1 into the bottom box 4-2, the rotating auger blades can push the steel shot along the length of the bottom box 4-2 to the discharge port, realizing continuous discharge. The continuous conveying method of the conveying auger 4-3 can effectively solve the problem of steel shot accumulation and blockage. Compared with traditional gravity discharge, the active pushing of the auger can adapt to the discharge requirements of steel shot of different particle sizes, avoiding discharge obstruction caused by steel shot agglomeration or uneven particle size. The bottom box 4-2 must be coaxial with the central hood 4-1 to ensure that the steel shot can fall smoothly from the central hood 4-1 into the auger conveying area of ​​the bottom box 4-2. The connection between the two ends of the conveying auger 4-3 and the bottom box 4-2 must be sealed to prevent steel shot dust from leaking from the connection gap, and to prevent foreign objects from entering the auger and causing jamming.

[0033] During operation, the centralized hood 4-1 receives the steel shot discharged from the vibrating screening component 3 and gathers it into the bottom box 4-2. The conveying auger 4-3 continuously pushes the steel shot out, thus achieving centralized collection and anti-clogging discharge of the steel shot and ensuring the smooth and efficient steel shot recycling process.

[0034] For example, such as Figure 1 As shown, a blocking cover 5 is provided on the upper surface of the swing plate 3-1, and an outlet 6 is provided on the surface of the blocking cover 5.

[0035] In some examples, the blocking cover 5 at the upper part of the surface of the swing plate 3-1 is made of bent steel plate and is fixed perpendicularly to the surface of the swing plate 3-1. Its height is adapted to the thickness of the steel shot stack and can surround the area above the screen plate 3-4. When the swing plate 3-1 rotates upward to discharge the steel shot, it can play a buffering role.

[0036] For example, such as Figure 3 As shown, the bottom of the recycling bin 1 is provided with a cleaning port 7, and the bottom of the recycling bin 1 is provided with a sliding cover 8, which is located below the cleaning port 7.

[0037] In some examples, the cleaning port 7 at the bottom of the recycling bin 1 is located directly below the slag discharge port 3-7 and communicates with the slag collection area inside the recycling bin 1. The cleaning port 7 is equipped with an openable and closable sealing cover. The sliding cover 8 at the bottom of the recycling bin 1 is fixed at an angle, with its upper end sealed to the edge of the cleaning port 7 and its lower end extending to the outside of the recycling bin 1.

[0038] For example, such as Figure 1 As shown, the swing plate 3-1 can be rotated 180° via the transmission control of the worm gear 3-10 and the worm wheel 3-8.

[0039] In some examples, the swing plate 3-1 is rotated 180° via a worm gear 3-10 and a worm wheel 3-8. This transmission combination has a precise transmission ratio, which enables precise control of the rotation angle of the swing plate 3-1.

[0040] In actual use: First, check whether the cleaning port 7 at the bottom of the recycling bin 1 is sealed tightly, and ensure that the sliding cover 8 is aligned with the bottom of the cleaning port 7. Then, start the drive motor 3-9 on the side surface of the recycling bin 1. Through the meshing transmission of the worm gear 3-10 and the worm wheel 3-8, adjust the swing plate 3-1 to a horizontal state so that the screen plate 3-4 can stably receive the steel shot. Then, start the vibration motors 3-12 at both ends of the horizontal plate 3-11. The vibration motors 3-12 drive the horizontal plate 3-11, the connecting frame 3-5, and the screen plate 3-4 to vibrate at high frequency. The buffer spring 3-6 on the connecting frame 3-5 absorbs the vibration impact on the back of the swing plate 3-1, avoiding direct damage to the structure of the swing plate 3-1. Slowly pour the steel shot from the casting production line onto the surface of the swing plate 3-1. The blocking cover 5 at the top of the swing plate 3-1 prevents the steel shot from splashing. After the steel shot falls onto the screen plate 3-4... Dust adhering to the surface falls into the rectangular trough 3-2 through the holes of the screen plate 3-4 under vibration, and then enters the slag collection area at the bottom of the recycling box 1 through the slag discharge port 3-7 in the trough. The shroud 3-13 on the side of the inner partition plate 2 can prevent dust from entering the vibrating motor 3-12 and protect the motor to operate normally. After screening, the drive motor 3-9 is reversed, and the worm gear 3-10 drives the worm wheel 3-8 and the swing plate 3-1 to rotate. The steel shot slides out from the discharge port 6 of the baffle 5 along the inclined screen plate 3-4 and falls into the collection shroud 4-1 at the bottom of the recycling box 1. The collection shroud 4-1 guides the steel shot to gather in the bottom box 4-2. The conveying auger 4-3 in the bottom box 4-2 rotates to continuously push the steel shot to the external recycling container. If it is necessary to clean the residual dust, the cleaning port 7 at the bottom of the recycling box 1 is opened, and the dust is discharged through the sliding cover 8, completing one steel shot recycling and screening process.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
