Description

Technical Field

[0001] This invention relates to the field of white fused alumina processing technology, specifically to a scrap filtering device and its usage method for white fused alumina processing. Background Technology

[0002] In the processing of white fused alumina, key components such as the jaw plates and grinding walls of jaw crushers and cone crushers are made of high manganese steel. Long-term compression and crushing of white fused alumina blocks will generate wear iron filings. In addition, the steel balls and steel segments used in ball mills and tube mills, as grinding media, will generate iron filings through friction and collision with the white fused alumina raw materials. Iron filings contamination will seriously affect the product quality of white fused alumina. Iron oxides will lower the melting point of white fused alumina and affect its high-temperature performance. Excessive iron content will darken the color of white fused alumina and affect the appearance of high-end products.

[0016] Preferably, the path grooves are symmetrically distributed on the outer surface of the mounting plate, and the path grooves are slidably connected to the limiting block.

[0017] A method for using a scrap filtering device for processing white corundum includes the following steps:

[0018] S1. In use, the mixed raw materials enter from the inclined hopper of the input distribution box. The movable buffer seat and the inner movable seat are linked. When the equalizing piston is activated, the movable buffer seat moves horizontally to block the fixed output slot, and at the same time, the downward-folding output plate loses its support and flips down, pouring the raw materials in the scrap buffer slot into the inner buffer slot. This process is reset by the reset spring, realizing periodic quantitative feeding synchronized with subsequent processes.

[0019] S2. The drive motor drives the inclined transmission belt to transmit power from bottom to top, and the output shaft rotates synchronously. The inclined connecting seat converts the rotational motion into the reciprocating swing of the driven pull arm and the traction arm, driving the driven piston to move back and forth in the inner buffer tank. Under the push of the driven piston, the raw material is evenly distributed from the gap between it and the tank wall to the equally distributed output tanks, realizing continuous and stable thin-layer material output;

[0020] S3. The evenly distributed material falls onto the inclined distribution belt, which moves upward synchronously with the drive belt. White corundum rolls downwards to the buffer boxes on both sides due to gravity; while iron filings are attracted by the magnetic array inside the conveyor belt. The magnetic array is arranged in a circular pattern in the inner rotating groove, controlled by the counterweight of the outer rotating seat, ensuring the strong magnetic surface always faces upwards, fixing the iron filings in the iron filings groove on the surface of the conveyor belt, and conveying them upwards with the belt.

[0021] S4. When the conveyor belt reaches the bottom, the limit block engages with the path groove of the side limit seat, forcing the magnetic array to rotate so that the weak magnetic surface faces upward. The weakened magnetic force causes the iron filings to fall off in the middle area at the bottom. After detaching from the path groove, the counterweight blocks turn the strong magnetic surface upward again. In the three bottom buffer boxes, the two sides collect pure white corundum, while the middle box specifically collects iron filings, completing the final separation.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] In this invention, the combined effect of gravity grading and directional magnetic adsorption achieves efficient separation of white fused alumina and iron filings. The upward-sloping conveyor belt causes the heavier white fused alumina to naturally roll downwards into the side buffer box due to gravity, while the iron filings are firmly adsorbed into the iron filings groove on the surface of the conveyor belt by the magnetic array. The magnetic array adopts a top-left-bottom-right cyclic arrangement, so that the magnetic field strength at the top is superimposed to form a strong magnetic surface, and the bottom cancels each other out to form a weak magnetic surface. Under the directional action of the counterweight of the outer rotating seat, the strong magnetic surface is always kept facing upwards, so that the iron filings are buffered in the groove. This ensures that the iron filings do not fall off during the entire transportation process and avoids magnetic interference with the rolling trajectory of the white fused alumina, significantly improving the separation purity and efficiency.

[0024] In this invention, the magnetic field switching effect of forced path turning and gravity reset achieves precise collection of iron filings and protection against mixing. When the conveyor belt runs to the bottom sides, the limiting block engages with the path groove, forcing the magnetic array to rotate so that the weak magnetic surface faces upward, causing the iron filings to lose their attraction in the middle area at the bottom and fall off. After leaving the path groove, the counterweight automatically rotates the strong magnetic surface back to the top by gravity, ensuring that the iron filings do not fall into the white corundum collection boxes on both sides. The three buffer boxes at the bottom are dedicated to collecting pure white corundum on both sides and iron filings in the middle. At the same time, the path groove continuously constrains the direction of the magnetic array during the return phase of the conveyor belt, preventing the magnetic force from recovering too early and re-attracting the collected iron filings, effectively eliminating cross-contamination.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1 to 20 The present invention provides a technical solution: a wire scrap filtering device for white corundum processing, comprising a device housing 1, an execution housing 11 fixedly connected to the outer surface of the device housing 1, a top support 12 fixedly connected to the top surface of the device housing 1, a buffer box 13 slidably connected to the inner surface of the device housing 1, a bidirectional drive belt 2 provided on the inner surface of the device housing 1, a distribution piston 3 provided on the inner surface of the execution housing 11, a powder distribution groove 4 provided on the inner surface of the execution housing 11, an input diversion box 5 provided on the top surface of the execution housing 11, a diversion belt 6 provided on the inner surface of the execution housing 11, and a side limiting seat 7 provided on the outer surface of the diversion belt 6.

[0048] There are three buffer boxes 13, with the two sides used to collect white corundum and the middle one used to collect fallen iron filings.

[0049] The bidirectional drive belt 2 includes a drive motor 21, which is fixedly connected to the inner surface of the execution housing 11. A transmission wheel 22 is fixedly connected to the output end of the drive motor 21. A transmission belt 23 is sleeved on the outer surface of the transmission wheel 22. An output shaft 24 is fixedly connected to the outer surface of the transmission wheel 22 on the other side of the transmission belt 23.

[0050] There are two drive wheels 22, both of which are rotatably connected to the inner surface of the actuator housing 11, and the drive belt 23 is sleeved on the outer surface of the symmetrical drive wheels 22.

[0051] With the bidirectional drive belt 2 in use, the drive motor 21 drives the transmission wheel 22 connected to it to rotate, and drives the transmission wheel 22 on the other side to rotate through the transmission belt 23. This allows the transmission belt 23 to rotate around the two transmission wheels 22 at the same time, and the output shaft 24 also rotates synchronously through the transmission wheel 22.

[0052] The transmission belt 23 mounted on the transmission wheel 22 is inclined, and the drive motor 21 drives the transmission belt 23 to move upward. Therefore, the white corundum rolls down due to gravity, while the iron filings are attracted and transported upward.

[0053] The equalizing piston 3 includes an inclined connecting seat 31, which is fixedly connected to the outer surface of the output shaft 24. A driven pull arm 311 is slidably connected to the outer surface of the inclined connecting seat 31. A rotating hinge seat 312 is rotatably connected to the outer surface of the driven pull arm 311. A traction arm 32 is hinged to the outer surface of the rotating hinge seat 312. A driven piston 33 is slidably connected to the other end of the traction arm 32. An inner buffer groove 34 is fixedly connected to the inner surface of the actuator housing 11. An equalizing output groove 341 is opened on the outer surface of the inner buffer groove 34. A delay pull rod 35 is slidably connected to the inner surface of the inner buffer groove 34.

[0054] The traction arm 32 is connected to the driven piston 33 via a universal ball joint. The driven piston 33 is slidably connected to the inner surface of the inner buffer slot 34. The evenly distributed output slots 341 are equidistantly distributed on the inner surface of the inner buffer slot 34. The delay rod 35 is slidably connected to the outer surface of the driven piston 33.

[0055] By setting the piston 3 evenly, during use, the inclined connecting seat 31 is connected to the output shaft 24 and rotates at a constant speed. During the rotation, the inclined connecting seat 31 changes its tilt direction with the rotation angle, and causes the driven pull arm 311 to swing back and forth. The rotating hinge seat 312 on the driven pull arm 311 is rotatably connected and hinged to the traction arm 32, so that the traction arm 32 is always aligned with the driven piston 33, thereby directly converting the rotation of the output shaft 24 into the reciprocating movement of the driven piston 33, thus simplifying the structure.

[0056] The driven piston 33 moves back and forth in the inner buffer tank 34. When the white corundum mixed with iron filings is placed inside the inner buffer tank 34, the raw material is pushed back and forth inside by the pushing action of the driven piston 33, so that it is evenly distributed in multiple equal distribution output tanks 341 and output.

[0057] The driven piston 33 is in contact with the inner wall of the inner buffer tank 34 at both ends, while the radial dimension of the middle section is small. The white corundum powder is output downward from the gap between the middle section of the driven piston 33 and the inner buffer tank 34 to the equal distribution output tank 341.

[0058] The delay rod 35 is sleeved on the surface of the driven piston 33 and is slidably connected to it. The large radial dimension of both ends of the driven piston 33 needs to contact the delay rod 35 to generate a pushing action, thereby producing a delay effect, so that the input white corundum powder is input into the gap in the middle section of the driven piston 33.

[0059] The powder dispensing tank 4 includes a fixed mounting base 41, which is fixedly connected to the top surface of the inner buffer tank 34. The top surface of the fixed mounting base 41 is fixedly connected with symmetrically distributed reset springs 411. The outer surface of the fixed mounting base 41 is provided with an embedding groove 412. The outer surface of the fixed mounting base 41 is slidably connected with a movable buffer base 42. The bottom surface of the movable buffer base 42 is hinged to a downward-folding output plate 421. The outer surface of the movable buffer base 42 is provided with a chip buffer groove 422.

[0060] The two ends of the reset spring 411 are fixedly connected to the fixed mounting base 41 and the movable buffer base 42 respectively. The movable buffer base 42 is slidably connected to the top surface of the inner buffer groove 34. The flip-down output plate 421 is slidably connected to the outer surface of the fixed mounting base 41. The flip-down output plate 421 is slidably connected to the delay rod 35.

[0061] With the setting of powder distribution tank 4, during use, the fixed mounting base 41 is fixed in position to install the reset spring 411 and support the flip-down output plate 421 at the bottom. When the movable buffer base 42 is still at the top of the fixed mounting base 41, the flip-down output plate 421 is supported by the fixed mounting base 41 and cannot be flipped down, thereby buffering the raw material inside the scrap buffer tank 422.

[0062] When the delay lever 35 is pushed, it will drive the movable buffer seat 42 to move on the fixed mounting seat 41 through the flip-down output plate 421 until the movable buffer seat 42 is separated from the fixed mounting seat 41 and loses its bottom support. Then the flip-down output plate 421 flips down to output the white corundum and iron filings inside the iron filings buffer groove 422 at the same time.

[0063] The movable buffer seat 42 receives the raw material output from the top housing 51 through the scrap buffer trough 422. When the movable buffer seat 42 is pushed, the rear of the movable buffer seat 42 will block the output port of the top housing 51, thus preventing output.

[0064] Until the delay lever 35 returns, the movable buffer seat 42 is pulled back under the action of the reset spring 411, the downward output plate 421 is lifted up by the fixed mounting seat 41 and merged again, and the scrap buffer trough 422 moves again to below the output port of the top housing 51 to receive a new round of raw materials, thus realizing the effect of inputting raw materials during each equal distribution process of the driven piston 33.

[0065] The input diversion box 5 includes a top outer shell 51, which is fixedly connected to the inner surface of the top support 12. A fixed output groove 511 is provided on the bottom surface of the top outer shell 51. An inclined hopper 512 is fixedly connected to the inner surface of the top outer shell 51. An inner movable seat 52 is slidably connected to the inner surface of the top outer shell 51. A traction rack 522 is fixedly connected to the outer surface of the inner movable seat 52. A driven gear seat 53 is rotatably connected to the inner surface of the top outer shell 51. A rotating column 531 is fixedly connected to the top surface of the driven gear seat 53. An elastic outer cylinder 532 is sleeved on the outer surface of the rotating column 531.

[0066] The inner movable seat 52 is fixedly connected to the movable buffer seat 42, and the traction rack 522 meshes with the driven rack seat 53.

[0067] By setting the input diversion box 5, during use, the top outer shell 51 feeds the mixture of white corundum and iron filings into the inclined hopper 512, and outputs it to the iron filings buffer hopper 422 through the fixed output hopper 511 at the top. The iron filings will be poured into the rear of the elastic outer cylinder 532 along the inclined hopper 512. When the movable buffer seat 42 moves, it will also drive the traction rack 522 to move. By meshing with the driven gear seat 53, the rotating column 531 and the elastic outer cylinder 532 will rotate inward or outward at the same time. When the traction rack 522 moves away, the driven gear seat 53 will rotate inward at the same time, which will squeeze the mixture of white corundum and iron filings inward and output it towards the fixed output hopper 511. The elastic outer cylinder 532 is relatively soft, and the mixture of white corundum and iron filings can only pass through the gap. During the squeezing process, it will be initially separated and moved to the fixed output hopper 511 to wait for output.

[0068] The diversion belt 6 includes a connecting clamp 61, which is fixedly connected to the outer surface of the transmission belt 23. A support shaft 611 is rotatably connected to the inner surface of the execution housing 11. A conveyor belt 62 is fixedly connected to the outer surface of the connecting clamp 61. A chip groove 621 is opened on the outer surface of the conveyor belt 62. An inner fixing groove 63 is fixedly connected to the inner surface of the conveyor belt 62. An inner partition 631 is fixedly connected to the inner surface of the inner fixing groove 63. An inner movable plate 632 is slidably connected to the inner surface of the inner partition 631. An inner rotating groove 633 is rotatably connected to the inner surface of the inner fixing groove 63. A magnetic array 6331 is fixedly connected to the inner surface of the inner rotating groove 633. An outer rotating seat 64 is fixedly connected to the outer surface of the inner fixing groove 63. A counterweight 641 is fixedly connected to the inner surface of the outer rotating seat 64. A limit block 642 is fixedly connected to the outer surface of the outer rotating seat 64.

[0069] The connecting clamps 61 are equidistantly distributed on the outer surface of the transmission belt 23. There are two supporting shafts 611, both of which are slidably connected to the inner surface of the conveyor belt 62. The chip troughs 621 are equidistantly distributed on the outer surface of the conveyor belt 62. The inner rotating groove 633 contacts the inner movable plate 632 and is fixedly connected to the outer rotating seat 64.

[0070] The side limiting seat 7 includes an outer bracket 71, which is fixedly connected to the inner surface of the execution housing 11. An mounting plate 72 is fixedly connected to the outer surface of the outer bracket 71, and a path groove 721 is formed on the outer surface of the mounting plate 72.

[0071] The path grooves 721 are symmetrically distributed on the outer surface of the mounting plate 72, and the path grooves 721 are slidably connected to the limiting block 642.

[0072] With the combined action of the diverting belt 6 and the side limiting seat 7, during use, the mixed raw material of white corundum and iron filings output from the equalizing piston 3 will fall onto the conveyor belt 62. The conveyor belt 62 is supported in an inclined position by the connecting clamps 61 on both sides and the support shaft 611. At the same time, since the connecting clamps 61 are connected to the transmission belt 23 for synchronous transmission, it also drives from bottom to top.

[0073] In this way, the white fused alumina rolls downwards under the influence of gravity and falls into the buffer box 13 on the side. Some of the white fused alumina, due to its poor rolling properties, is still transported upwards with the conveyor belt 62 and falls into the buffer box 13 on the other side.

[0074] During the impact vibration generated when the white corundum rolls and falls, the surface iron filings will fall off onto the surface of the conveyor belt 62 and be absorbed into the iron filings trough 621.

[0075] The inner side of the conveyor belt 62 is fitted with an inner rotating groove 63 that can rotate. The magnetic array 6331 inside is arranged in a circular pattern of top left bottom right, so that the magnetic field strength at the top is added together to increase the magnetic field strength to form a strong magnetic surface, while the magnetic field strength at the bottom cancels each other out to reduce the attraction force to form a weak magnetic surface. The inner fixed groove 63 is affected by the counterweight 641 of the outer rotating seat 64. When it is in the upper position, the strong magnetic surface is fixed upward, thereby adsorbing the iron filings particles entrained in the white fused alumina. Since the areas where the magnetic field strength is added are arranged at intervals and the arrangement position is aligned with the iron filings groove 621, the iron filings will be fixedly adsorbed into the iron filings groove 621, so as not to affect the rolling of the white fused alumina on the conveyor belt 62.

[0076] When the inner fixed groove 63 moves to the bottom following the transmission of the conveyor belt 62, it is still affected by the counterweight 641 of the outer rotating seat 64 to keep the strong magnetic surface facing upward, so that the weak magnetic surface faces the conveyor belt 62. Then the magnetic force below the conveyor belt 62 is reduced, so that the iron filings are no longer attracted and fall off.

[0077] The inner movable plate 632 can move inside the inner partition 631, thereby adapting to the lifting effect when the inner rotating groove 633 rotates;

[0078] The outer rotating seat 64 is not continuously affected by the counterweight 641. When it moves to both sides with the conveyor belt 62, the limiting block 642 will fall into the path groove 721 of the mounting plate 72. In this way, at both ends of the conveyor belt 62, the outer rotating seat 64 will force the strong magnetic surface of the magnetic array 6331 to align with the conveyor belt 62, and will not be affected by the counterweight 641 to rotate. In this way, when the iron filings are above the buffer box 13 on the bottom side, they are still attracted by the magnetic array 6331. After the iron filings are removed from the area above the buffer box 13, the limiting block 642 will disengage from the path groove 721 and be affected by gravity again to rotate the strong magnetic surface of the magnetic array 6331 to the top, so that the iron filings need to be in the middle area of ​​the bottom to fall. The two sides of the three buffer boxes 13 at the bottom are used to buffer white corundum, and the middle is used to buffer the falling iron filings.

[0079] Since the conveyor belt 62 is inclined and conveys from bottom to top, it will pass through three buffer boxes 13 in sequence when it is at the bottom. When it passes the first buffer box 13, it is still magnetically attracted by the path groove 721, and the iron filings will not fall into the buffer box 13. It needs to be moved to the middle buffer box 13 for the iron filings to fall off. When it moves to the last buffer box 13, it is again affected by the path groove 721. Until it is at the top and leaves the path groove 721, the magnetic array 6331 will keep the weak magnetic surface facing the conveyor belt 62 to prevent the magnetic attraction on the surface of the conveyor belt 62 from being restored in advance and to attract the iron filings in the middle buffer box 13.

[0080] In this embodiment, as Figure 1 , Figure 2As shown, each component is located inside the device housing 1 and the execution housing 11. The device housing 1 is equipped with a bidirectional drive belt 2 for driving, and the execution housing 11 is equipped with the remaining components for performing the separation and filtration effect.

[0081] In this embodiment, as Figure 3 The bidirectional drive belt 2, the equalizing piston 3, the powder distribution groove 4, and the flow distribution belt 6 work together in combination;

[0082] In this embodiment, as Figure 4 , Figure 5 , Figure 6 As shown, the drive motor 21 simultaneously drives the transmission belt 23 and the driven piston 33 to reciprocate.

[0083] In this embodiment, as Figure 7 , Figure 8 , Figure 9 As shown, the powder distribution tank 4 is located at the bottom of the input distribution box 5. The input distribution box 5 is initially separated by the movement of the movable buffer seat 42, and the raw materials are input downwards.

[0084] In this embodiment, as Figure 10 , Figure 11 As shown, the top outer shell 51 feeds white corundum and iron filings mixed raw material into the inclined hopper 512, and outputs it to the iron filings buffer tank 422 through the fixed output trough 511 at the top;

[0085] In this embodiment, as Figure 12 , Figure 13 , Figure 14 As shown, the conveyor belt 62 is supported at an angle by the connecting clamps 61 on both sides and the support shaft 611.

[0086] In this embodiment, as Figure 15 , Figure 16 As shown, the inner side of the conveyor belt 62 is fitted with an inner rotating groove 63 that can rotate through the inner fixed groove 63. The outer rotating seat 64 can drive the inner rotating groove 633 to rotate under the influence of the counterweight 641, and it faces upward most of the time.

[0087] In this embodiment, as Figure 17 , Figure 18 As shown, the magnetic array 6331 is arranged in a Heilbeck array, with solid and hollow elements representing the N pole and S pole respectively. The magnetic field lines at the top leave the N pole and diverge to the S pole on both sides. Adjacent individual magnets have the same direction and superimpose each other. The magnetic force at the top is enhanced, while the direction at the bottom cancels each other out. Each individual magnet repeats the same magnetic field line cycle, achieving magnetic force directional concentration.

[0088] In this embodiment, as Figure 19 , Figure 20As shown, when the conveyor belt 62 moves to both sides, the conveyor belt 62 at both ends and the bottom sides maintains the magnetic attraction effect through the action of the path groove 721, thereby outputting the iron filings to the buffer box 13 in the middle and avoiding them from being dispersed to the buffer boxes 13 on both sides.

[0089] The invention relates to a method of using and advantages of a scrap filter for white corundum processing, the working process of which is as follows:

[0090] like Figures 1 to 20 As shown, during use, the mixed raw materials enter from the inclined hopper 512 of the input distribution box 5. The movable buffer seat 42 is linked with the inner movable seat 52. When the equalizing piston 3 is activated, the movable buffer seat 42 moves horizontally to block the fixed output slot 511, and at the same time, the downward-folding output plate 421 loses its support and flips down, pouring the raw materials in the scrap buffer slot 422 into the inner buffer slot 34. This process is reset by the reset spring 411, realizing periodic quantitative feeding synchronized with subsequent processes.

[0091] The drive motor 21 drives the inclined transmission belt 23 to transmit power from bottom to top, and the output shaft 24 rotates synchronously. The inclined connecting seat 31 converts the rotational motion into the reciprocating swing of the driven pull arm 311 and the traction arm 32, driving the driven piston 33 to move back and forth in the inner buffer tank 34. Under the push of the driven piston 33, the raw material is evenly distributed from the gap between it and the tank wall to the equally distributed output tanks 341, realizing continuous and stable thin-layer material output;

[0092] The evenly distributed material falls onto the inclined diversion belt 6, and the conveyor belt 62 moves upward synchronously with the drive belt 23. White corundum rolls downwards to the buffer boxes 13 on both sides due to gravity; while iron filings are attracted by the magnetic array 6331 inside the conveyor belt 62. The magnetic array 6331 is arranged in a circular pattern in the inner rotating groove 633, controlled by the counterweight 641 of the outer rotating seat 64, ensuring that the strong magnetic surface always faces upwards, fixing and attracting the iron filings into the iron filings groove 621 on the surface of the conveyor belt 62, and conveying them upwards with the belt.

[0093] When the conveyor belt 62 reaches the bottom, the limiting block 642 engages with the path groove 721 of the side limiting seat 7, forcing the magnetic array 6331 to rotate so that the weak magnetic surface faces upward. The weakened magnetic force causes the iron filings to fall off in the middle area at the bottom. After disengaging from the path groove 721, the counterweight block 641 turns the strong magnetic surface upward again. In the three bottom buffer boxes 13, the sides collect pure white corundum, while the middle box specifically collects iron filings, completing the final separation.

[0094] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.

When in use, the mixed raw materials enter from the inclined hopper (512) of the input diversion box (5). The movable buffer seat (42) is linked with the inner movable seat (52). When the equalizing piston (3) is started, the movable buffer seat (42) moves to block the fixed output groove (511).
