Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for machining, and specifically to an abrasive flow recovery device. Background Technology

[0002] In the field of machining, abrasive flow machining technology is widely used in processes such as surface polishing, deburring, and precision dimensional finishing of parts. During abrasive flow machining, abrasive flow passes through the surface of the part to be machined under high pressure to achieve precision machining. However, the abrasive flow after machining often contains a large number of impurities, debris, and abrasive particles consumed due to wear. If it is discharged directly, it will not only waste resources and increase production costs, but also pollute the environment.

[0003] Existing abrasive stream recovery methods have many problems: On the one hand, traditional filtration methods are difficult to effectively separate tiny impurities and fine abrasive particles from the abrasive stream, resulting in low purity of the recovered abrasive stream, which will affect processing accuracy and quality when reused; on the other hand, most existing recovery devices have complex structures, and manual replacement of filter media is cumbersome, increasing labor intensity and reducing recovery efficiency.

[0012] A further improvement of this utility model is that: the snap-fit ​​mechanism includes abutting rods; one side of the filter cylinder has two sets of grooves that respectively communicate with the two sets of mounting grooves; each groove has an insertion slot near both ends; one side of the insertion slot has two sets of through slots symmetrically arranged; the inner wall of one side of the insertion slot has two sets of snap-fit ​​slots that are staggered with the two sets of through slots; one side of the mounting bracket has movable slots near both ends; a sleeve is slidably connected to the inner side of the movable slot and is connected to the sleeve by a spring; a sliding rod is slidably connected to the inner side of the sleeve; one end of the sliding rod is connected to a knob; and the outer ring of the other end of the sliding rod has two sets of abutting rods symmetrically arranged to match the two sets of through slots and the two sets of snap-fit ​​slots respectively.

[0013] The above technical solution, through its snap-fit ​​mechanism design, facilitates quick replacement of the coarse and fine filter layers, thereby improving the maintenance efficiency of the device.

[0031] The present invention will be further described in detail below with reference to embodiments:

[0032] Example 1

[0033] like Figure 1-6 As shown, this utility model provides an abrasive flow recovery device, including a recovery box 1. The top of the recovery box 1 is provided with a feed inlet 4. The inner side of the recovery box 1, below the feed inlet 4, is provided with two sets of support rods 5 and slidably connected to a filter cylinder 6. One side of the filter cylinder 6 is provided with a swing mechanism to facilitate its reciprocating motion. A filter mechanism is installed inside the filter cylinder 6. A first guide chamber 26 is provided below the filter cylinder 6. A magnetic separation mechanism to facilitate the screening of metal impurities is installed below the first guide chamber 26. A second guide chamber 33 is provided below the magnetic separation mechanism. A centrifugal separator 34 to facilitate further purification and separation of the abrasive flow is installed at the bottom of the inner side of the recovery box 1, below the second guide chamber 33. The bottom of the centrifugal separator 34 is provided with an abrasive discharge port 35 and a waste outlet 36, both of which extend to the outside of the recovery box 1.

[0034] In this embodiment, the abrasive stream enters the filter cylinder 6 through the feed inlet 4. The filtration mechanism inside the filter cylinder 6 can separate larger particles and impurities. At the same time, the filter cylinder 6 reciprocates under the drive of the swing mechanism, which can prevent the filter layer from clogging. The filtered abrasive stream flows out from the bottom of the filter cylinder 6, enters the first guide chamber 26, and flows into the magnetic separation mechanism. The magnetic separation mechanism can adsorb metal impurities in the abrasive stream. The non-magnetic abrasive stream flows out from the magnetic separation mechanism, enters the second guide chamber 33, and flows into the centrifugal separator 34. The centrifugal force separates the abrasive stream from the remaining waste. Finally, the pure abrasive stream is discharged from the abrasive discharge port 35, and the waste is discharged from the waste outlet 36. Thus, through the above structure, the abrasive stream can be efficiently recovered, ensuring the effective separation of waste and metal impurities.

[0035] like Figure 1-6 As shown, preferably, the filtration mechanism includes a coarse filter layer 10 and a fine filter layer 11. Two sets of mounting grooves 7 are respectively opened from top to bottom on the inner side of the filter cylinder 6. Mounting brackets 9 are installed on the inner side of each of the two sets of mounting grooves 7. The coarse filter layer 10 and the fine filter layer 11 are respectively installed on the inner side of each of the two sets of mounting brackets 9. Both sets of mounting brackets 9 are connected to the filter cylinder 6 through a snap-fit ​​mechanism that facilitates easy assembly and disassembly. After the abrasive flow enters the filter cylinder 6, it first passes through the coarse filter layer 10. The coarse filter layer 10 intercepts larger particles and impurities, initially purifying the abrasive flow. The abrasive flow after passing through the coarse filter layer 10 continues to flow downwards into the fine filter layer 11. The fine filter layer 11 can further filter fine particles and micron-sized impurities, ensuring the high purity of the abrasive flow. Thus, through this design, impurities in the abrasive flow can be efficiently separated.

[0036] like Figure 1-6 As shown, preferably, the coarse filter layer 10 is made of metal wire mesh, and the fine filter layer 11 is made of high-precision nanofiber filter membrane. The metal wire mesh can intercept larger particles and impurities in the abrasive flow and protect the fine filter layer 11 from clogging. The nanofiber filter membrane has high precision and small pore size, and can filter fine particles and micron-sized impurities.

[0037] like Figure 1-6As shown, preferably, the locking mechanism includes abutment rods 17. Two sets of grooves 8, each communicating with one set of mounting grooves 7, are provided on one side of the filter cylinder 6. Insertion grooves 18 are provided near both ends of each groove 8. Two sets of through grooves 19 are symmetrically provided on one side of each insertion groove 18. Two sets of locking slots 20, alternating with the two sets of through grooves 19, are provided on the inner wall of one side of each insertion groove 18. Movable grooves 12 are provided near both ends of one side of the mounting bracket 9. A sleeve 13 is slidably connected to the inner side of the movable groove 12 and connected to the sleeve 13 via a spring 14. A sliding rod 15 is slidably connected to the inner side of the sleeve 13. A knob 16 is connected to one end of the sliding rod 15. Two sets of abutment rods 17, each adapted to the two sets of through grooves 19 and the two sets of locking slots 20, are symmetrically provided on the outer ring of the other end of the sliding rod 15. By pressing the knob 16, the knob 16 can compress the sleeve 13 and the spring 14. Simultaneously, knob 16 can drive slide rod 15 and two sets of abutment rods 17 to move to one side. The two sets of abutment rods 17 can move along the two sets of through slots 19 to the inside of insertion slot 18. Then, by rotating knob 16, knob 16 can drive slide rod 15 and two sets of abutment rods 17 to rotate. When the two sets of abutment rods 17 rotate to align with the two sets of slots 20, knob 16 is released. Under the action of the reaction force of spring 14, sleeve 13 and knob 16 can be driven to move in the opposite direction. Knob 16 can drive slide rod 15 and two sets of abutment rods 17 to move in the opposite direction and engage with the two sets of slots 20, thereby completing the installation and fixing of mounting bracket 9, coarse filter layer 10 and fine filter layer 11. The mounting bracket 9, coarse filter layer 10 and fine filter layer 11 can be disassembled by reversing the operation. Thus, by setting up, the disassembly and assembly of the filter mechanism can be facilitated, so as to facilitate equipment maintenance.

[0038] like Figure 1-6 As shown, preferably, the swing mechanism includes a first motor 23. A fixing plate 21 is provided at the center of one side of the filter cylinder 6. An abutment groove 22 is provided on one side of the fixing plate 21. The first motor 23 is installed on one side of the recycling box 1. The output end of the first motor 23 extends to the inner side of the recycling box 1 and is connected to a rotating plate 24. A rotating rod 25 that matches the abutment groove 22 is installed near the edge of the rotating plate 24. The first motor 23 can drive the rotating plate 24 to rotate, and the rotating rod 25 on the rotating plate 24 rotates with the rotating plate 24. 5 During rotation, the contact groove 22 is pushed, causing the filter cylinder 6 to move to one side along the two sets of support rods 5. When the rotating rod 25 rotates to a certain angle, the reaction force of the contact groove 22 causes the filter cylinder 6 to move to the other side along the two sets of support rods 5, thus forming the reciprocating motion of the filter cylinder 6. The oscillation of the filter cylinder 6 causes the abrasive flow to flow continuously during the filtration process, improving the filtration efficiency. The oscillation makes it difficult for impurities to accumulate on the surface of the filter layer, extending the service life of the filter layer. Thus, by setting it up, the filtration efficiency can be effectively improved and the filter layer can be prevented from clogging.

[0039] like Figure 1-6As shown, preferably, the magnetic separation mechanism includes a magnetic system 29. A fixed shaft is provided inside the recovery box 1, and a roller 27 is rotatably connected to the outer ring of the fixed shaft. A second motor 28 is installed on one side of the recovery box 1 to facilitate the rotation of the roller 27. The magnetic system 29 is installed on the inner wall of the outer ring of the fixed shaft near the roller 27. A groove 30 is provided on the outer side of the roller 27. A sliding groove 31 is opened on one side of the recovery box 1, and a collection box 32 is slidably connected to the inner side of the sliding groove 31. The collection box 32 is located below the roller 27 on the side away from the groove 30. The roller 27 can be driven to rotate by the second motor 28, and the abrasive flow flows from the first guide chamber. When the abrasive particles flow out of the roller 26 and pass through the roller 27, the metal impurities in the abrasive particle stream are attracted by the strong magnetic field of the magnetic system 29 and adhere to the surface of the roller 27. The non-magnetic abrasive particles slide off the surface of the roller 27 and enter the second guide chamber 33. As the roller 27 continues to rotate, the attracted metal impurities will rotate with the roller 27. When the roller 27 rotates to a position away from the magnetic system 29, the metal impurities are removed from the magnetic field. The metal impurities removed from the magnetic field can fall into the collection box 32 in the chute 31 for collection. Thus, by setting up the roller 26, the metal impurities in the abrasive particle stream can be efficiently separated, ensuring the purity of the abrasive particle stream, while also facilitating cleaning and maintenance.

[0040] like Figure 1-6 As shown, preferably, a maintenance door 2 is installed on one side of the recycling bin 1, and four sets of support legs 3 are provided at the bottom of the recycling bin 1. The maintenance door 2 facilitates the inspection, maintenance and repair of the equipment inside the recycling bin 1, and the support legs 3 ensure that the equipment remains balanced and stable during operation.

[0041] The working principle of this abrasive flow recovery device will be explained in detail below.

[0042] like Figure 1-6 As shown, firstly, the abrasive flow enters the filter cylinder 6 through the feed inlet 4, and first passes through the coarse filter layer 10. The coarse filter layer 10 intercepts larger particles and impurities. The abrasive flow after passing through the coarse filter layer 10 continues to flow downward into the fine filter layer 11. The fine filter layer 11 further filters out fine particles and micron-sized impurities. Then, the roller 27 can be driven to rotate by the second motor 28. When the abrasive flow flows out from the first guide chamber 26 and flows through the roller 27, the metallic impurities in the abrasive flow are attracted by the strong magnetic field of the magnetic system 29 and adhere to the surface of the roller 27. The non-magnetic abrasive flow flows out of the roller. The metal impurities slid off the surface of the roller 27 and entered the second guide chamber 33. As the roller 27 continued to rotate, the adsorbed metal impurities rotated with the roller 27. When the roller 27 rotated to a position away from the magnetic system 29, the metal impurities were removed from the magnetic field. The metal impurities removed from the magnetic field could fall into the collection box 32 for collection. The non-magnetic abrasive flow flowed into the centrifugal separator 34 through the second guide chamber 33. The centrifugal force could separate the abrasive flow from the remaining waste. Finally, the pure abrasive flow was discharged from the abrasive discharge port 35, and the waste was discharged from the waste outlet 36.

[0043] When assembling or disassembling the mounting bracket 9, the coarse filter layer 10, and the fine filter layer 11, pressing the knob 16 compresses the sleeve 13 and the spring 14. Simultaneously, the knob 16 moves the sliding rod 15 and the two sets of contact rods 17 to one side. The two sets of contact rods 17 move along the two sets of through slots 19 to the inside of the insertion slot 18. Rotating the knob 16 then rotates the sliding rod 15 and the two sets of contact rods 17. When aligned with the two sets of slots 20, release the knob 16. Under the reaction force of the spring 14, the sleeve 13 can be driven to move the knob 16 in the opposite direction. The knob 16 can drive the slide rod 15 and the two sets of abutting rods 17 to move in the opposite direction and engage with the two sets of slots 20, thereby completing the installation and fixing of the mounting bracket 9, the coarse filter layer 10 and the fine filter layer 11. The mounting bracket 9, the coarse filter layer 10 and the fine filter layer 11 can be disassembled by reversing the operation, thus completing the entire operation process.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
