Description

Technical Field

[0001] This utility model belongs to the field of graphite electrode processing technology, and in particular relates to a graded recycling mechanism for shot blasting residue from graphite electrode cutting. Background Technology

[0002] After the shot blasting (or surface impurity removal) process of large-size, high-precision graphite electrodes is completed, the mixed residue discharged from the discharge end of the shot blasting equipment (including wear shot blasting media of different particle sizes, graphite cutting chips, and oxide layer impurities on the electrode surface) needs to be graded at the end of the graphite electrode continuous production line. This involves screening out reusable shot blasting media and classifying and collecting graphite impurities of different sizes. Our mechanism is adapted to the residue grading and recycling operation at this station.

[0003] In this scenario, existing shot blasting residue classification and recycling technologies differ from our institution's technologies in the following key ways and have the following shortcomings:

[0004] Differences in structural adaptability: Most existing recycling devices use grids / screens with fixed spacing as the screening structure, which can only be adapted to the classification of residues with a single particle size; a few adjustable devices require manual adjustment of the spacing of the support components one by one, without synchronous control components, and cannot adapt to the multi-particle-size classification requirements of residues from shot blasting of graphite electrodes of different specifications.

[0005] Differences in adjustment accuracy and efficiency: Existing manual adjustment devices cannot guarantee the consistency of the spacing between each support component, which can easily lead to small-diameter impurities being mixed into the shot blasting process, and the adjustment is time-consuming.

[0006] Differences in operational synergy: The screening structures of existing recycling devices are mostly static or unidirectional vibrating, which cannot improve the efficiency of waste material flow through the circumferential rotation of the screening structure. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides a graded recycling mechanism for shot blasting residue from graphite electrode cutting, thus solving the problems mentioned in the background section.

[0008] The technical solution of this utility model is as follows:

[0009] A grading and recycling mechanism for graphite electrode shot blasting residue includes: two supports for mounting and a support plate rotatably connected to the supports. Several support members are circumferentially distributed between the two support plates. A drive component is provided on one side of the support plate, and a spacing adjustment component is provided on the other side of the support plate. The spacing adjustment component is connected to each of the support members and is used to drive all the support members to synchronously adjust the spacing between adjacent members, so as to achieve grading and screening of graphite electrode shot blasting residue with different particle sizes.

[0010] Furthermore, the drive assembly includes a first gear and a second gear that mesh with each other. The first gear is rotatably connected to the bracket, and the second gear is fixedly connected to the output end of the motor. The outer periphery of the bearing disk is provided with tooth blocks, which mesh with the first gear.

[0011] Furthermore, the spacing adjustment assembly includes slide rails distributed circumferentially along the bearing plate, with sliders slidably fitted on the slide rails, and the end of the support member fixedly connected to the sliders; a guide groove is provided between adjacent slide rails, with a sliding rod slidably fitted in the guide groove, and rigid connecting rods stacked on both sides hinged to the sliding rods, with the end of the connecting rod away from the sliding rod hinged to the corresponding slider; the spacing adjustment assembly also includes a drive unit, which is fixed to at least one slider through a connecting plate.

[0012] Furthermore, one of the sliders is provided with a fixing plate, and the output end of the telescopic rod fixedly connected to the bearing plate is connected to the fixing plate.

[0013] Furthermore, the ends of the two connecting rods pass through the slider, and when they are brought together, their ends protrude from the slider.

[0014] Furthermore, the telescopic rod's extension and retraction movement can drive the slider to slide on the slide rail, thereby achieving adjustment of the support component's position.

[0015] Compared with the prior art, the beneficial effects of the technical solution provided by this utility model are as follows:

[0016] (1) By setting the spacing adjustment component, the shot blasting residue of different particle sizes can be quickly adapted. This not only ensures the uniformity of the spacing between each support component and improves the purity of the graded screening, but also realizes the integrated grading of multiple specifications of residue, greatly enhancing the adaptability of the mechanism to different working conditions in the processing of graphite electrodes.

[0017] (2) By setting the drive component, the support can be rotated for screening, which accelerates the flow speed of the residual material between the support and avoids the accumulation and jamming of the residual material in the screening area. At the same time, it ensures that the fine residual material can pass through the gap and the coarse particles can be effectively intercepted. Attached Figure Description

[0022] 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, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] See Figure 1-3 A grading and recycling mechanism for graphite electrode shot blasting residue includes: two supports 1 for mounting and a support plate 3 rotatably connected to the supports 1. Several support members 4 are circumferentially distributed between the two support plates 3. A driving component is provided on one side of the support plate 3, and a spacing adjustment component is provided on the other side of the support plate 3. The spacing adjustment component is connected to each of the support members 4 and is used to drive all the support members 4 to synchronously adjust the spacing between adjacent ones, so as to achieve grading and screening of graphite electrode shot blasting residue with different particle sizes.

[0024] Specifically, the support 1 is a vertical U-shaped structure with a mounting base at the bottom. The inner side of the support 1 is fixed with an annular component 2, and the inner side of the annular component 2 has a sliding groove. The support 1 is fixed at the end of the shot blasting process and the recovery station ensures that the two supports 1 are coaxial and supports the bearing plate 3 to rotate smoothly. The edge of the bearing plate 3 is embedded in the sliding groove of the annular component 2 to achieve circumferential rotation.

[0025] The drive assembly starts, driving the bearing disk 3 on this side to rotate circumferentially along the annular component 2 of the support 1; the bearing disk 3 on the other side rotates synchronously with the support component 4, so that all the support components 4 form a rotating annular screening surface; the mixed residue after the graphite electrode cutting shot blasting (including shot blasting media of different particle sizes, graphite fragments, etc.) falls from above into the space between the rotating support components 4. Using the action of centrifugal force and gravity, the small particles of residue fall through the gaps in the support components 4 (entering the lower collection device), while the large particles of residue are intercepted, achieving preliminary classification;

[0026] When different particle sizes of residual material need to be screened, the spacing adjustment component is activated to make the support members 4 synchronously converge (decrease the spacing) or disperse (increase the spacing) to adjust the adjacent gaps. After the spacing adjustment is completed, the rotation screening process of the support members 4 continues to adapt to the new particle size grading requirements. In order to prevent the residual material in the support members 4 from splashing everywhere during screening, a sleeve 13 is fixedly connected to the annular component 2. The bottom end of the sleeve 13 has a strip-shaped discharge port. The sleeve 13 wraps the support members 4 inside, forming a relatively closed space, which effectively limits the splashing range of the residual material during the screening process. When the support members 4 rotates for screening, the residual material inside the sleeve 13 is subjected to the combined action of centrifugal force and gravity. Small particles of residual material pass through the gaps in the support members 4 and fall to the lower collection device through the strip-shaped discharge port at the bottom end of the sleeve 13. Large particles of residual material are trapped on the support members 4 and are discharged with the rotation after the spacing of the support members 4 increases. The upper end of the sleeve 13 is provided with a feed port.

[0027] like Figure 1 and Figure 2 As shown, the drive assembly includes a first gear 5 and a second gear 6 that mesh with each other. The first gear 5 is rotatably connected to the bracket 1, and the second gear 6 is fixedly connected to the output end of the motor 7. The outer periphery of the bearing disk 3 is provided with a toothed block 31, which meshes with the first gear 5.

[0028] Specifically, the bottom end of the annular component 2 is provided with a through groove relative to the position of the first gear 5, and connecting blocks are fixedly connected to both sides of the bottom end of the annular component 2. The first gear 5 has a shaft hole in the center and a matching metal rotating shaft. The two ends of the rotating shaft are assembled in the connecting blocks through rolling bearings. The tooth blocks 31 are continuously distributed along the outer periphery of the bearing disk 3. The tooth blocks 31 are adapted to the teeth of the first gear 5. The tooth blocks 31 and the bearing disk 3 are integrally formed or welded and fixed, forming a complete annular tooth ring along the outer periphery of the bearing disk.

[0029] The motor 7 is started, and the output shaft drives the second gear 6 to rotate at a stable speed. The second gear 6 transmits power to the first gear 5 through gear meshing, causing the first gear 5 to rotate around its own axis. The first gear 5 then meshes with the outer peripheral tooth block 31 of the bearing disk 3, causing the bearing disk 3 to rotate circumferentially along the annular member 2 on the support 1. Finally, the bearing disk 3 drives the support members 4 on both sides to rotate synchronously, forming a continuously rotating screening surface.

[0030] like Figure 3As shown, the spacing adjustment assembly includes slide rails 9 distributed circumferentially along the support plate 3, with sliders 11 slidably fitted on the slide rails 9, and the end of the support member 4 fixedly connected to the sliders 11; guide grooves 10 are provided between adjacent slide rails 9, with sliding rods 12 slidably fitted in the guide grooves 10, and rigid connecting rods 14 stacked on both sides hinged to the sliding rods 12, with the end of the connecting rod 14 away from the sliding rod 12 hinged to the corresponding slider 11; the spacing adjustment assembly also includes a drive unit, which is fixed to at least one slider 11 through a connecting plate; a fixing plate 16 is provided on one of the sliders 11, and the output end of the telescopic rod 15 fixedly connected to the support plate 3 is connected to the fixing plate 16; the ends of the two connecting rods 14 pass through the sliders 11, and when they move inward, their ends protrude from the sliders 11; through the telescopic movement of the telescopic rod 15, the sliders 11 can be driven to slide on the slide rails 9, thereby realizing the adjustment of the position of the support member 4.

[0031] Specifically, the slide rail 9 is a long strip-shaped guide rail structure, radially distributed along the circumference of the support plate 3, with a T-shaped cross-section (to prevent the slider from falling off); the bottom of the slide rail 9 has a fixing hole, which is connected to the surface of the support plate 3 by fasteners. The surface of the slide rail 9 is smooth to reduce the sliding resistance of the slider 11; at the location corresponding to the movement trajectory of the slider 11 on the support plate 3, there is a long strip hole extending radially (the hole diameter is larger than the diameter of the support member 4, leaving a movement gap) to avoid interference between the support member 4 and the support plate; the end of the support member 4 that passes through the support plate must be connected to the slider 11 using a rigid fixing structure (such as bolt fastening, pin positioning) to ensure that the power transmission is not loose and does not affect the sliding of the slider along the slide rail 9; the part of the support member 4 that passes through the support plate 3 must maintain a straight shape to avoid bending that would cause poor power transmission; the end of the support member 4 can be stepped or threaded to facilitate fixing to the slider;

[0032] The bearing plate 3 on the symmetrical side of the spacing adjustment component is provided with grooves 32 arranged in the same manner as the slide rail 9. The other end of the support member 4 is installed on the groove 32. The groove 32 limits the sliding of the support member 4, ensuring that it always maintains parallel linkage with the slide rail 9 during the spacing adjustment process, avoiding spacing adjustment errors caused by radial offset. To prevent residual material from rolling into the groove 32 during operation, a protective cloth is arranged between the support member 4 and the groove 32. The protective cloth is made of high-strength synthetic fiber material, which has excellent wear resistance and tear resistance, and can effectively resist the impact of rolling residual material. During installation, the protective cloth is fixed to the upper and lower surfaces of the support member 4 with bolts and extends to the bottom edge of the groove 32 to form a continuous protective barrier. This design not only prevents residual material from sliding into the groove 32, but also facilitates regular disassembly, cleaning and maintenance, ensuring long-term reliable operation of the equipment. In addition, a sealing strip is added to the edge of the protective cloth to further enhance the sealing effect and prevent fine particles from penetrating.

[0033] The slider 11 has a through hole inside for the ends of the two connecting rods 14 to pass through. The diameter of the through hole is larger than the diameter of the connecting rod 14 to ensure smooth movement of the connecting rod 14. When the slider moves inward, the ends of the connecting rods 14 can protrude from the through hole. The rigid connecting rods 14 are arranged in pairs, stacked on the left and right sides (to avoid interference between adjacent components).

[0034] When slider 11 moves to the maximum spacing position (support 4 is most divergent): telescopic rod 15 is in a fully extended state, and the output end pushes fixed plate 16 and corresponding slider 11 to move along slide rail 9 to the outermost end of slide rail (slide rail 9 is equipped with a limiting structure to prevent slider 11 from falling out); all sliders 11 move synchronously along their respective slide rail 9 towards the outer periphery of bearing plate 3, the spacing between adjacent sliders 11 reaches the maximum value, and the screening gap formed by support 4 is the largest; the hinge points at both ends of connecting rod 14 are fully opened, and sliding rod 12 is pushed by connecting rod 14 to the outermost end of guide groove 10 (in the same direction as slider 11); the end of connecting rod 14 retracts into the through hole of slider 11 and does not protrude from the surface of slider 11 to avoid interference with other components; slider 11 is against the outer limit of slide rail 9, telescopic rod 15 is locked, all linkage components are in a state of tension balance, the spacing of support 4 remains stable, and it is suitable for the classification of large particle waste materials (such as large-size shot blasting media, coarse graphite blocks);

[0035] Slider 11 moves to the minimum spacing position (support 4 is most converged), the gap size is adapted to the grading requirements of small particle residue (shot blasting), telescopic rod 15 is in the fully retracted state, the output end of telescopic rod 15 pulls fixed plate 16 and corresponding slider 11 to move along slide rail 9 to the innermost end of slide rail 9 (close to the center of bearing plate 3); all sliders 11 move towards the center of bearing plate 3 simultaneously, the spacing between adjacent sliders 11 reaches the minimum value, and the screening gap formed by support 4 is minimized; connecting rod 14 is in a folded and retracted state, the hinge points at both ends are close to each other, and the sliding... The moving rod 12 is pulled to the innermost end of the guide groove 10 by the connecting rod 14; the ends of the two stacked connecting rods 14 pass through the through holes of the slider 11, and the ends protrude from the inner surface of the slider 11 (due to the reduced spacing, there is no space to accommodate the ends of the connecting rods 14 after folding, so they naturally extend out and do not affect the operation of the structure); the slider 11 is stopped against the inner side of the slide rail 9, and the telescopic rod 15 is locked. The connecting rod 14 and the sliding rod 12 form a compact linkage structure. The support members 4 are evenly spaced and stable, which is suitable for the classification of small particle residues (such as fine graphite chips and small-sized wear shot blasting).

[0036] Work process:

[0037] (1) Initial preparation: Before the stage mechanism is started, the telescopic rod 15 is in the middle position, the slider 11 is in the middle position of the slide rail 9, and the support 4 maintains a medium distance; the spacing adjustment component is stationary with the bearing plate 3, and the drive component is not started.

[0038] Based on the particle size requirements of the remaining material to be graded, the operator determines the target spacing (maximum / minimum / intermediate value) and sets the extension stroke of the telescopic rod 15.

[0039] (2) Adjust to the maximum spacing (to accommodate large particle residue)

[0040] When the spacing adjustment system is activated, the telescopic rod 15 begins to extend after receiving a signal, and pushes the slider 11 connected to it to move outward along the slide rail 9 through the fixed plate 16.

[0041] The slider 11 transmits thrust through the hinged connecting rod 14, causing the sliding rod 12 to slide outward synchronously within the guide groove 10; the sliding rod 12 then pushes the adjacent slider 11 to move outward along the slide rail through the connecting rod 14 on the other side, thus linking all the sliders in sequence.

[0042] When the first slider 11 comes into contact with the outer limit of the slide rail 9, the telescopic rod 15 stops extending and locks, all sliders reach the maximum spacing position simultaneously, and the support 4 forms the maximum screening gap.

[0043] When the drive assembly is activated, the bearing plate 3 drives the support component 4 to rotate, and large particles fall from above into the screening surface. Only large-sized particles are retained, while small particles fall naturally, thus completing the grading of large particles.

[0044] (3) Switch to minimum spacing (suitable for small particle residue)

[0045] After the large particles are classified, the drive component is paused (or kept rotating at a low speed without affecting the pitch adjustment), and the telescopic rod 15 begins to retract after receiving the switching signal;

[0046] The telescopic rod 15 pulls the fixed plate 16 and the corresponding slider 11 to move towards the center of the bearing plate 3. The slider pulls the sliding rod 12 to slide inward in the guide groove 10 through the connecting rod 14.

[0047] The sliding rod 12 pulls the adjacent slider 11 inward in sync through the connecting rod 14 on the other side. All sliders move inward along the slide rail, and the connecting rod 14 gradually folds and retracts.

[0048] When the first slider 11 is stopped by the inner limit of the slide rail 9, the telescopic rod 15 stops retracting and locks, all sliders reach the minimum spacing position, the end of the connecting rod 14 protrudes from the through hole of the slider 11, and the support 4 forms the minimum screening gap.

[0049] Restart the drive component, and small particles of residual material fall into the screening surface. Fine particles pass through the gaps, while slightly larger particles are trapped, thus completing the small particle classification.

[0050] (4) Reset and adjustment of intermediate spacing

[0051] After grading is completed, the telescopic rod 15 is reset to the middle position, the slider 11 returns to the middle position of the slide rail, and the spacing of the support 4 is restored to the initial state, waiting for the next batch of residual material to be processed;

[0052] If it is necessary to filter particles of intermediate size, the telescopic rod 15 only extends to the preset stroke (not reaching the limit position), and the slider 11 stays at the corresponding position of the slide rail. The spacing is kept stable by locking the telescopic rod, which can adapt to diverse grading needs.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be covered within the protection scope of the present utility model.
