The frequency motor 30 and the slewing mechanism 40. The receiving portion 26 is disposed under the fixing portion 22, and the receiving portion 26 has a first opening 262 and a second opening 264. The opening edge of the first opening 262 is connected to the fixing portion 22 and disposed on the rotating portion. At the periphery of the mechanism 40, the second opening 264 can be opened as needed. The receiving portion 26 further has a dirty liquid port 266 and a clean liquid port 268. The dirty liquid port 266 is provided with a dirty liquid pipe for the sewage liquid to enter, and the clean liquid port 268 supplies the clean liquid away from the variable frequency telecentric separator. 10. The power unit 28 is provided in the receiving portion 26 for supplying electric power to other portions of the variable frequency telecentric separator 10.

The variable frequency motor 30 has a transmission shaft 31. The rotation speed of the inverter motor 30 can be adjusted according to requirements. The faster the motor rotation speed, the more the abrasive or debris of small particle size can be separated from the dirty liquid. In the present embodiment, the variable speed motor 30 has a rotational speed of 500 to 1500 revolutions per minute.

2 to 4, the swing mechanism 40 has a rotary pot 42 and a rotating shaft 44. The rotary pot 42 has a top cover 422, a barrel 424, a liquid outlet 426 and a chip outlet 428. The upper edge of the barrel 424 is connected to the top cover 422. The liquid outlet 426 extends through the top cover 422. The lower edge of the barrel 424 forms the chip outlet 428. The center of the top cover 422 is further recessed by a recess 423, and the center of the recess 423 is connected to the rotating shaft 44.

The rotating shaft 44 is fixed to the fixing portion 22 by a pair of first bearings 46. A first end 442 of the rotating shaft 44 protrudes from the top cover 422 and protrudes from the fixing portion 22, and a driving belt 32 is sleeved thereon. The first end 442 of the rotating shaft 44 and the transmission shaft 31 are rotated by the variable frequency motor 30. A second end 444 of the rotating shaft 44 extends into the rotating pot 42.

The variable frequency telecentric separator 10 further has a protective cover 48 connected to the fixing portion 22 and extending downwardly on the rotating shaft 44. At the same time, the protective cover 48 is received in the recess 423 of the top cover 422. The function of the protective cover 48 is to isolate the rotating shaft 44 from the external environment and to prevent the rotation of the rotating shaft 44 from being disturbed. In other preferred embodiments, the protective cover 48 can be omitted, and the top cover 422 can have a flat surface without the recess 423. The center of the top cover 422 is directly It is connected to the rotating shaft 44. The variable frequency telecentric separator 10 that does not have the protective cover 48 or the recess 423 can still achieve the function of separating the debris, the abrasive, and the polishing liquid, respectively.

The cleaning mechanism 50 has a squeegee shaft 52 and a squeegee 54. The squeegee shaft 52 is disposed in the rotating shaft 44 by the two second bearings 56, so that the squeegee shaft 52 and the rotating shaft 44 are relatively rotatable, and the two ends of the squeegee shaft 52 respectively protrude from the rotating shaft The first end 442 and the second end 444 of the 44 are connected to the squeegee 54 by the squeegee shaft 52 protruding from the second end 444. The squeegee 54 has a disc 542 and two wings 544. The center of the disc 542 is connected to the squeegee shaft 52. The two wings 544 are located at opposite positions and are respectively connected to the outer edge of the disc 542. The outer edge of each of the wings 544 has a scraping surface 541, and each of the scraping surfaces 541 is matched with the inner wall surface of the rotary pot 42, that is, each scraping surface 541 undulates along the inner wall surface, for example, in the inner wall surface. The scraping surface 541 of the convex portion is also recessed. At the same level, the distance D1 between the squeegee shaft 52 and the scraping surface 541 is smaller than the distance D2 between the squeegee shaft 52 and the inner wall of the barrel 424.

In other preferred embodiments, the squeegee 54 having at least one of the wings 544 can scrape the debris attached to the barrel 424, in fact, as long as the squeegee 54 has a scraping surface 541 for scraping The debris attached to the barrel 424 is sufficient. Therefore, the configuration of the scraping surface 541 does not necessarily correspond to the inner wall surface of the barrel 424, and even the wing portion 544 is not necessary. In addition, the disc 542 can guide the sewage discharged from the dirty liquid pipe to splash around, but the variable frequency telecentric separator 10 without the disc 542 can still separate the functions of separating the debris, the abrasive and the polishing liquid. .

The top of the squeegee shaft 52 protruding from the first end 442 has a second limiting slot 522. The second limiting slot 522 provides a reserved space for an external tool, such as a T-shaped wrench. The squeegee shaft 52 is rotated. Without the second limiting slot 522, the external tool can still be coupled to the squeegee shaft 52 by means of clips, tongs, etc., without compromising the function of the variable frequency telecentric separator 10.

The variable frequency telecentric separator 10 further has a small pot 70, The small pot 70 contents the opening 72 of the liquid drain tube, the function of which is to keep the dirty liquid nozzle from being blocked by falling debris. The opening 72 of the small pot 70 faces downward, and the pot top 74 of the small pot 70 is connected to the lower side of the disc 542. The pot top 74 of the small pot 70 has at least one hollow portion 76. In other preferred embodiments, the pan top 74 of the cuvette 70 can be located below the squeegee 54 and directly coupled to the squeegee shaft 52. Even the variable frequency telecentric separator 10 not having the small pot 70 can achieve the function of separating the chips, the abrasive, and the slurry separately.

The limiting mechanism 60 has a latching rod 62 and a first limiting slot 64. The latching pin 62 is disposed on the fixing portion 22 and does not move with the rotating mechanism 40. The first limiting slot 64 is disposed on the top cover 422. The latch 62 is detachably disposed in the first limiting slot 64. When the latch 62 is inserted into the first limiting slot 64, the rotating mechanism 40 is fixed and cannot be rotated. Otherwise, when the latch 62 is disengaged from the first limiting slot 64, the rotating mechanism 40 can be subjected to the variable frequency motor. 30 drive and rotate.

In other preferred embodiments, the latch 62 can be disposed at a fixed position, and the fixed position does not move with the swing mechanism 40. The first limiting slot 64 can be disposed at other positions of the rotary pot 42 so that when The plug 62 is inserted into the first limiting slot 64 to fix the rotary pot 42.

Next, the usage status of this creation will be explained.

When the debris, the abrasive and the slurry are to be separated, the inverter motor 30 is started to operate at an appropriate rotation speed, and the rotary shaft 44 is driven to rotate the rotary pan 42 while the dirty liquid pipe passes the dirty liquid port 266 to remove the dirty liquid. The opening 72 of the small pot 7 (0) is poured into the small pot 70, and the dirty liquid passes through the hollow portion 76 and is blocked by the disc 542, and is sprayed in all directions to the rotary pot 42. The centrifugal force is applied by the rotary pot 42 The liquid will be smashed toward the inner wall surface of the barrel 424, wherein the larger particle size will stay on the inner wall surface of the barrel 424, and the abrasive liquid and the medium-sized abrasive (ie, the cleaning liquid) will gradually move toward the barrel. The body 424 moves upwards and finally flows out of the rotary pot 42 via the upper liquid outlet 426, and then the body 20 is led out through the clean liquid port 268. During the separation process, the The rotation speed of the inverter motor 30 controls the particle size of the abrasive contained in the cleaning liquid discharged from the liquid outlet 426. For example, if the inverter motor 30 is set to rotate at a high speed and then rotate at a low speed, the variable frequency telecentric separator 10 will first be exported to include the relative A small amount of abrasive liquid, and then a clean liquid containing relatively large abrasives. It can be seen that the variable frequency telecentric separator with the variable frequency motor can separate the abrasives, and can also separate the abrasive containing the abrasive of a specific particle size range according to requirements.

If it is desired to remove debris remaining on the inner wall surface of the barrel 424, the inverter motor 30 is first stopped and the swing mechanism 40 is allowed to stand still. Then, the latch 62 is placed in the first limiting slot 64, and then the T-shaped wrench is placed into the second limiting slot 522 and the T-shaped wrench is rotated to rotate the scraper shaft 52. At this time, the squeegee 54 attached to the squeegee shaft 52 also rotates, and the rotary pot 42 is restrained by the limiting mechanism 60 to ensure rest, so that the scraping surfaces 541 located in the respective wing portions 544 are opposite to the same. The inner wall surface of the barrel 424 is rotated to scrape off the debris, and the scraped debris is dropped through the swarf opening 428. Finally, the fallen debris can be collected and removed at the second opening 264.

According to the test, the variable frequency telecentric separator of the present invention can separate the abrasive of 95% of the particle size of 10 μm or more in the dirty liquid, and can also separate the abrasive of 70% of the particle size of 5 μm or more in the dirty liquid.
