Description

Technical Field

[0001] The present invention relates to the technical field of coating recycling devices, and specifically refers to a lost foam coating recycling and treatment device. Background Art

[0002] When coating a lost foam, to ensure the uniformity and quality of the coating, usually some extra coating is prepared. However, in actual operation, since it is difficult to accurately control the amount of coating used, there will be some remaining coating that eventually dries up and becomes solid waste. In addition, when casting some large cast iron parts, a large amount of coating layer will peel off as the foam pattern burns and disappears after demoulding, and accumulates around the casting site. These peeled-off lost foam coatings usually still contain a large amount of effective components and are relatively concentrated. Recycling and treatment can save a large amount of coating raw material expenses.

[0003] For large solid coating waste, usually a crusher is used to crush it into smaller particles. The crushed waste is then screened by a vibrating screen to remove larger impurities and particles that do not meet the particle size requirements. However, the vibration amplitude of traditional screening devices is relatively fixed. When encountering coating waste with high viscosity, the relatively small vibration amplitude is difficult to make the coating particles move sufficiently, and the foam residues are easy to accumulate on the screen and block the screen holes. After the blockage occurs, since the vibration amplitude cannot be increased in a timely manner to assist in clearing the blockage, the screen hole blockage will become more and more serious, seriously affecting the production continuity.

[0006] Further, a wedge-shaped groove is provided on the movable slider, a wedge-shaped slider is movably arranged in the wedge-shaped groove, and the first ball hinge seat is fixedly arranged on the wedge-shaped slider.

[0007] Further, extension grooves are extended at both ends of the wedge-shaped groove, vertical plates are fixedly arranged at the ends of the extension grooves, a threaded rod is movably arranged on the vertical plates through bearings, a threaded hole is penetrated through the wedge-shaped slider, the threaded rod penetrates through the threaded hole, and a rotating wheel is fixedly arranged at the end of the threaded rod.

[0008] Further, extension blocks are extended at both ends of the movable slider, the axis of the extension block is vertically intersecting with the axis of the extension groove, a sliding hole is provided on the extension block, and the movable slider is movably arranged on the guide rod through the sliding hole.

[0009] In a further embodiment, a return spring is sleeved on the guide rod, the lower end of the return spring abuts against the support block, and the upper end of the return spring is fixedly abutted against the extension block.

[0010] In a further embodiment, a sieve mesh is provided on the lower wall of the sieve frame, and the sieve mesh is detachably arranged.

[0011] Further, the base includes a bottom frame, a front bracket and a rear bracket. The front bracket is fixedly arranged in a U-shaped shape at the front end of the bottom frame, the rear bracket is fixedly arranged in an L-shaped shape at the rear end of the bottom frame, and the support block of the vibration assembly is fixedly arranged at the end of the rear bracket.

[0012] In a further embodiment, a first support spring is provided on the front bracket, the lower end of the first support spring is fixedly arranged on the front bracket, and the upper end of the first support spring is fixedly arranged on the lower wall of the hopper.

[0015] The beneficial effects obtained by the present invention with the above structure are as follows: The turntable is driven by a driving motor. Since the second ball hinge seat is eccentrically arranged on the turntable, the ball hinge connecting rod generates a spatial motion, thereby driving the first ball hinge seat and the movable slider to vibrate up and down along the guide rod. Compared with the traditional simple linear vibration or circular vibration, the material can be more fully turned and dispersed in the sieve frame, effectively avoiding local accumulation of the material on the sieve surface and improving the screening efficiency. The ball hinge connecting rod with spatial motion drives the sieve frame to vibrate, causing the sieve frame to generate vibration components in different directions. The material can contact the sieve mesh from multiple angles, which helps particles of different shapes and sizes pass through the sieve mesh more smoothly, further improving the screening accuracy. By moving the position of the second ball hinge seat, the vibration amplitude of the sieve frame can be changed, making the coating particles jump more violently on the sieve mesh, breaking the agglomeration of the coating particles, accelerating the movement speed of the coating particles, enabling the coating particles to pass through the sieve mesh faster, and improving the screening efficiency.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments; based on the embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection.

[0020] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the embodiments.

[0021] For large chunks of solid coating waste, a crusher is usually used to crush it into smaller particles. The crushed waste is then screened through a vibrating screen to remove larger impurities and particles that do not meet the particle size requirements. However, the vibration amplitude of traditional screening devices is relatively fixed. When encountering coating waste with a relatively high viscosity, the relatively small vibration amplitude is difficult to make the coating particles move sufficiently, and foam residues are likely to accumulate on the screen and block the screen holes. After the blockage occurs, since the vibration amplitude cannot be increased in a timely manner to assist in clearing the blockage, the screen hole blockage situation will become more and more serious, seriously affecting the production continuity.

[0022] After recognizing the above problems, the present application proposes and discloses a lost foam coating recycling and treatment device, which can timely adjust the vibration amplitude to assist in clearing the blockage and dredge the screen holes blocked by foam residues, improving the screening efficiency and screening quality.

[0023] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, the embodiments of the present disclosure provide a lost foam coating recycling and treatment device, including a base 1, having a front end and a rear end with unequal heights, and the height of the front end is lower than the height of the rear end; The vibration assembly 2 is provided with two groups, and the two groups of vibration assemblies 2 are oppositely arranged on the rear end of the base 1. The vibration assembly 2 includes a support block 3, a guide rod 4, a support plate 5, a drive motor 6, a turntable 7, a movable slider 8 and a ball hinge connecting rod 9. The guide rods 4 are symmetrically arranged at both ends of the support block 3. The support plate 5 is connected and arranged on the two guide rods 4. The drive motor 6 is fixedly arranged on the support plate 5 and the output shaft end of the drive motor 6 movably penetrates through the support plate 5. The turntable 7 is fixedly arranged at the output shaft end of the drive motor 6. The movable slider 8 is slidably arranged up and down on the two guide rods 4. An eccentric first ball hinge seat 10 is arranged on the movable slider 8. A second ball hinge seat 11 is arranged on the lower wall of the turntable 7. One end of the ball hinge connecting rod 9 is movably arranged on the first ball hinge seat 10, and the other end of the ball hinge connecting rod 9 is movably arranged on the second ball hinge seat 11; The fixed connecting rod 12, and the end parts of the fixed connecting rod 12 are respectively fixedly arranged on the lower walls of the movable sliders 8 of the two groups of vibration assemblies 2; The hopper 13, one end of which is inclined and arranged on the fixed connecting rod 12, and the other end is arranged on the front end of the base 1; The sieve frame 14, which is inclined and arranged on the hopper 13.

[0024] In this embodiment, after the solid coating waste is crushed by a crusher, the smaller particles after crushing are put into the sieve frame 14. Subsequently, the output shaft end of the drive motor 6 can drive the second ball hinge seat 11 to rotate in a circular motion through the turntable 7. Since the second ball hinge seat 11 is eccentrically arranged on the turntable 7, the ball hinge connecting rod 9 is driven to move by the second ball hinge seat 11. Because both ends of the ball hinge connecting rod 9 are movably connected to the first ball hinge seat 10 and the second ball hinge seat 11 respectively, the ball hinge connecting rod 9 will generate a spatial motion under the drive of the second ball hinge seat 11, thereby pushing the first ball hinge seat 10 and the movable slider 8 connected thereto to vibrate up and down on the guide rod 4. Then, the movable slider 8 drives the fixed connecting rod 12 to vibrate up and down, vibrating and screening the hopper 13 and the sieve frame 14, and screening out larger impurities, such as possible mixed wood blocks, plastic fragments, etc. and particles that do not meet the particle size requirements.

[0025] Such as Figure 3 and Figure 4 As shown, a wedge-shaped groove 15 is arranged on the movable slider 8, and a wedge-shaped slider 16 is movably arranged in the wedge-shaped groove 15. The first ball hinge seat 10 is fixedly arranged on the wedge-shaped slider 16.

[0026] Such as Figure 3 and Figure 4 As shown, extension grooves 17 are extended at both ends of the wedge-shaped groove 15, vertical plates 19 are fixedly arranged at the ends of the extension grooves 17, a threaded rod 20 is movably arranged on the vertical plates 19 through bearings, a threaded hole 21 is penetrated through the wedge-shaped slider 16, the threaded rod 20 penetrates through the threaded hole 21, and a runner 22 is fixedly arranged at the end of the threaded rod 20.

[0027] Such as Figure 3 and Figure 4As shown, extension blocks 23 are provided at both ends of the movable slider 8. The axis of the extension block 23 is perpendicular to the axis of the extension slot 17. A sliding hole 24 is provided on the extension block 23, and the movable slider 8 is movably arranged on the guide rod 4 through the sliding hole 24.

[0028] In this embodiment, the rotation of the threaded rod 20 can be driven by the runner 22. The threaded rod 20 drives the wedge-shaped slider 16 to slide in the wedge-shaped groove 15 through threaded connection, thereby driving the first ball hinge seat 10 to move. When the first ball hinge seat 10 moves horizontally away from the center of the turntable 7, its eccentricity increases. When the turntable 7 rotates, the stroke of the first ball hinge seat 10 in the circular motion increases, and the displacement transmitted to the movable slider 8 through the ball hinge connecting rod 9 also increases. Accordingly, the amplitude of the up-and-down fluctuation of the movable slider 8 also becomes larger, and the movable slider 8 drives the amplitude of the sieve frame 14 to increase through the fixed connecting rod 12. When the first ball hinge seat 10 moves horizontally toward the center of the turntable 7, its eccentricity decreases, the stroke of the first ball hinge seat 10 in the circular motion decreases, the displacement transmitted to the movable slider 8 decreases accordingly, and the amplitude of the up-and-down fluctuation of the movable slider 8 becomes smaller. The movable slider 8 drives the amplitude of the sieve frame 14 to decrease through the fixed connecting rod 12.

[0029] When screening paint waste with relatively high viscosity, such as when foam residues accumulate on the sieve mesh 26 and block the sieve holes, the threaded rod 20 drives the wedge-shaped slider 16 and the first ball hinge seat 10 to move horizontally away from the center of the turntable 7 through threads to increase the vibration amplitude, making the paint particles jump more violently on the sieve surface, breaking the agglomeration of the paint particles, enabling the paint particles to be better dispersed on the sieve surface, and accelerating the movement speed of the paint particles, so that the paint particles can pass through the sieve mesh 26 faster, improving the screening efficiency.

[0030] After the blockage is cleared, the threaded rod 20 drives the wedge-shaped slider 16 and the first ball hinge seat 10 to move horizontally toward the center of the turntable 7 through threads to reduce the vibration amplitude, making it difficult for particles close to the sieve hole size to pass through the sieve holes, improving the screening quality, reducing the impact force of the paint particles on the sieve mesh 26, and reducing the wear degree of the sieve mesh 26, thereby prolonging the service life of the sieve mesh 26.

[0031] As Figure 1 、 Figure 2 and Figure 3 As shown, a return spring 25 is sleeved on the guide rod 4. The lower end of the return spring 25 abuts against the support block 3, and the upper end of the return spring 25 is fixedly abutted against the extension block 23.

[0032] When the movable slider 8 moves up and down driven by the ball hinge connecting rod 9, the return spring 25 plays a role of assisting and buffering during the process of being compressed and restored to its original state, thereby reducing the force that the ball hinge connecting rod 9 needs to bear when driving the movable slider 8, reducing the load of the ball hinge connecting rod 9, and reducing its wear and fatigue.

[0033] The elastic action of the return spring 25 enables the vibration generated by the movable slider 8 during the up-and-down undulation to continuously impact and shake the materials on the screen 26, thereby preventing the materials from accumulating on the screen 26 or clogging the screen holes, enabling the materials to pass through the screen 26 more smoothly, and improving the screening efficiency.

[0034] As Figure 1 shown, a screen 26 is provided on the lower wall of the screen frame 14, and the screen 26 is detachably arranged.

[0035] During the first screening process, a screen 26 with a pore size of 10 - 15 mm can be selected for rough screening to quickly remove larger lumpy impurities, such as large unbroken bauxite, caked coatings, etc., and prevent them from entering the subsequent screening process and causing blockage or damage to the equipment; for the secondary screening, a screen 26 with a pore size of 3 - 5 mm can be selected for fine screening. The fine screen 26 can more specifically screen the remaining smaller coating particles, improving the screening efficiency and quality.

[0036] As Figure 1 and Figure 2 shown, the base 1 includes a bottom frame 27, a front bracket 28, and a rear bracket 29. The front bracket 28 is fixedly arranged in a U-shape at the front end of the bottom frame 27, and the rear bracket 29 is fixedly arranged in an L-shape at the rear end of the bottom frame 27. The support block 3 of the vibration assembly 2 is fixedly arranged at the end of the rear bracket 29.

[0037] As Figure 1 and Figure 2 shown, a first support spring 30 is provided on the front bracket 28. The lower end of the first support spring 30 is fixedly arranged on the front bracket 28, and the upper end of the first support spring 30 is fixedly arranged on the lower wall of the hopper 13.

[0038] As Figure 1 and Figure 2 shown, a second support spring 31 is provided on the rear bracket 29. The lower end of the second support spring 31 is fixedly arranged on the rear bracket 29, and the upper end of the second support spring 31 is fixedly arranged on the lower wall of the fixed connecting rod 12.

[0039] As Figure 1 and Figure 2 shown, a coarse material discharge port 32 is provided on the front wall of the screen frame 14, and the coarse material discharge port 32 is arranged close to the front bracket 28.

[0040] In this embodiment, during the screening process, the larger coarse materials will move gradually from the rear end to the front end of the screen frame 14 on the surface of the screen 26 and finally be directly discharged from the coarse material discharge port 32.
