Description
Technical Field
[0001] The utility model relates to a double-sided polishing machine, in particular to a polishing liquid transfer and recovery device used for the double-sided polishing machine. Background Art
[0002] In automated double-sided polishing equipment, polishing fluid is the main processing consumable and is consumed in huge quantities. In order to reuse it efficiently, the polishing fluid processed by the double-sided polishing equipment is often discharged into the filtering equipment, filtered by the filtering equipment and then reused. In order to achieve automated and efficient production, the polishing fluid discharge port of the double-sided polishing equipment will be connected to the liquid inlet of the filtering equipment to realize automatic filtration circulation. In order to meet the needs of large volume, the liquid inlet of the filtering equipment is often set higher, and in order to allow the polishing fluid inside the polishing machine to be discharged smoothly, the discharge port will be set very low. This causes the height requirements of the liquid inlet of the filtering equipment and the polishing fluid discharge port to conflict, making them difficult to match.
[0003] To address these issues, the current approach involves raising the operating base of the double-sided polisher. This imposes special foundation requirements on the polisher's operating environment, increasing the equipment's plant configuration costs. Furthermore, varying equipment base heights can make operation inconvenient for operators, thus impacting the polisher's processing efficiency. Therefore, developing a transfer-type polishing liquid recovery device that can achieve transfer output of polishing liquid without having to consider the height matching between the filter inlet and the polishing liquid outlet has become a technical problem urgently needed by those skilled in the art. Summary of the Invention
[0004] The utility model is to solve the above-mentioned technical problems and provides a polishing liquid transfer and recovery device for a double-sided polishing machine. The purpose is to achieve the transfer output of the polishing liquid of the double-sided polishing machine without specially matching the height of the liquid inlet of the filtering equipment and the discharge outlet of the polishing liquid, and without setting up a special height foundation.
[0005] In order to achieve the above purpose, the present invention is implemented through the following technical solutions:

As shown Figure 4 As shown, the maintenance door 11 is provided with two circular mounting holes for installing the door lock 1101, and a rectangular hole is opened in the middle of the maintenance door 11 for installing the handle 1102. The upper part of the box body 1 is provided with a grooved end cover 3, as shown in FIG. Figure 3 As shown, the structure of the groove-shaped end cover 3 is as follows: a rectangular hollow circular upper cover 301 is set at the upper end of the box body 1, and a storage tank 302 is fixedly installed at the lower part of the circular upper cover 301. The upper end surface of the circular upper cover 301 and the storage tank 302 are bonded into an integral structure by bonding. A partition 308 is longitudinally set inside the storage tank 302. The partition 308 divides the storage tank 302 into two left and right tanks, the right side of which is the overflow tank 304 and the left side of which is the filter tank 309. The left and right sides of the middle of the filter tank 309 are bonded. Connecting strap 303, filter plate 4 is mounted on connecting strap 303. Filter plate 4 is provided with multiple evenly spaced small circular holes. An upper circular hole 307 is provided on the front side of filter tank 309. Upper liquid level sensor 12 is mounted in upper circular hole 307. A lower circular hole is provided at the bottom of filter tank 309. A circular liquid inlet 306 is bonded to the lower circular hole. Liquid inlet 306 communicates with valve line 10. A circular seepage port 305 is bonded to the lower end of overflow tank 304. Seepage port 305 communicates with drain line 7. An inlet cap 8 is provided on the upper end surface of storage tank 302. A circular polishing liquid inlet 801 is bonded to the upper left side of inlet cap 8. A circular through-hole 802 is provided on the right side of inlet cap 8. Inlet cap 8 is connected to storage tank 302 via cap screws 803. The inlet end cap 8 and the circular upper cover plate 301 form the top plate of the housing 1. A drainage pump 5 is installed below the filter tank 309 within the housing 1. The drainage pump 5 is connected to a valve line 10, which is equipped with a manual valve 9.

[0025] The working principle of this utility model is as follows:
[0026] The polishing liquid from the double-sided polishing machine enters the filter tank 309 through the polishing liquid inlet 801 on the inlet end cap 8 at the top of the housing 1. Large impurities are filtered out by the filter plate 4, which is densely perforated with circular holes. The filtered polishing liquid then flows through the liquid inlet 306 below the filter tank 309 and, via the manual valve 9, into the drainage pump 5, thereby achieving intermediate output of the polishing liquid. If excessive polishing liquid accumulates in the filter tank 309 due to a blockage or other malfunction, the upper liquid level sensor 12 on the front side of the storage tank 302 will trigger an alarm. Simultaneously, the excess polishing liquid overflows into the overflow tank 304 on the left side of the storage tank 302 and is discharged through the drainage pipe 7 below the overflow tank 304. A maintenance door on the front of the housing 1 provides convenient access to the interior of the polishing liquid recovery unit for inspection and maintenance. This eliminates the need for matching the height of the filter inlet and the polishing liquid discharge port, allowing for limited connection of the polishing liquid. It simplifies the operating environment requirements, saves operating space, and thus improves work efficiency.
