Description

Technical Field

[0001] This application relates to the field of polishing processes, and more particularly to a filter drain pipe. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical processes to reduce the surface roughness of a workpiece, thereby obtaining a bright and smooth surface. It involves using polishing tools and abrasive particles or other polishing media to refine the surface of a workpiece, and polishing is typically performed using polishing equipment.

[0003] In order to improve the polishing accuracy, existing single-sided polishing equipment usually adds polishing fluid during the product processing. The polishing fluid is delivered to the surface of the product to assist polishing by passing the polishing fluid through the liquid pipe. However, as the polishing fluid flows to the outlet of the liquid pipe, it is easy to crystallize on the wall of the liquid pipe. During the processing, the crystal particles may fall off and flow into the surface of the product along with the polishing fluid. The crystallization of the polishing fluid can easily cause scratches on the product surface during the polishing process, thus affecting the polishing of the processed product.

Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] This application discloses a filter drain pipe, as shown in the embodiments below. Figure 1 and Figure 2The system includes a pipe body 1, with a flow channel 2 extending through the pipe body 1 along its length. One end of the pipe body 1 is connected to a copper polishing liquid source via a connecting hose, and the other end of the pipe body 1 is equipped with a filter mechanism 3. The filter mechanism 3 is located in the polishing area of ​​the polishing equipment and provides polishing liquid for polishing. The filter mechanism 3 includes a filter sleeve 31 and a filter screen 32. The filter sleeve 31 is a circular sleeve and is fitted onto the pipe body 1. The filter screen 32 is installed on the filter sleeve 31 and covers the flow channel 2 at one end of the pipe body 1. By installing the filter screen 32 on the pipe body 1, the crystallized polishing liquid is filtered, thereby reducing the probability of polishing liquid crystals falling onto the surface of the processed product and reducing the impact of the crystals formed by the polishing liquid on polishing.

[0030] Reference Figure 2 and Figure 3 The filter sleeve 31 has a placement groove 4 at one end. The placement groove 4 is an annular groove and communicates with the inner wall of the filter sleeve 31 to form a stepped groove. The filter screen 32 includes a mounting ring 321 and a screen body 322. The mounting ring 321 is an annular ring that fits into the placement groove 4. The mounting ring 321 is placed in the placement groove 4, and when the mounting ring 321 is placed in the placement groove 4, the inner wall of the mounting ring 321 is flush with the inner wall of the filter sleeve 31. The screen body 322 is fixed to the mounting ring 321. Inside the tube 1, one end of the tube body 1 is inserted into the placement groove 4 and abuts against the mounting ring 321. The insertion of the tube body 1 allows the filter tube sleeve 31 to be fitted onto the tube body 1. The tube body 1 abuts against the mounting ring 321 to prevent the mounting ring 321 from detaching from the placement groove 4, thereby fixing the screen 322. When the filter screen 32 is damaged or needs to be cleaned, the filter screen 32 can be removed for replacement or cleaning by disassembling the filter tube sleeve 31, which facilitates the replacement and cleaning of the filter screen 32.

[0031] Reference Figure 2 and Figure 3 A sealing ring 5 is embedded in the side wall of the placement groove 4. The sealing ring 5 is an elastic rubber ring. When the tube body 1 is inserted into the placement groove 4, the sealing ring 5 abuts against the side wall of the tube body 1 inserted into the placement groove 4, thereby reducing the probability of polishing liquid leaking from the connection between the tube body 1 and the filter sleeve 31. The setting of the sealing ring 5 can improve the sealing performance at the connection between the filter sleeve 31 and the tube body 1 and reduce the probability of polishing liquid leakage. A reinforcing bolt 6 is threaded on the filter sleeve 31. The reinforcing bolt 6 penetrates the filter sleeve 31 and abuts against the side wall of the tube body 1. The reinforcing bolt 6 can reinforce the filter sleeve 31 on the tube body 1 and reduce the probability of the filter sleeve 31 falling off the tube body 1. The reinforcing bolt 6 is set at the end of the sealing ring 5 away from the tube body 1 and abutting against the mounting ring 321, so that the sealing effect of the sealing ring 5 can also be effective for the installation of the reinforcing bolt 6.

[0032] Reference Figure 1 and Figure 2The pipe body 1 includes a valve plate 11, an inlet pipe 12, and an outlet pipe 13. The inlet pipe 12 and the outlet pipe 13 are respectively installed at both ends of the valve plate 11 along its length. Both the inlet pipe 12 and the outlet pipe 13 are metal round pipes. The valve plate 11 is a rectangular metal block. The inlet pipe 12 and the outlet pipe 13 are inserted and installed on the valve plate 11 with an interference fit. The flow channel 2 passes through the valve plate 11, the inlet pipe 12, and the outlet pipe 13. The flow channels 2 on the inlet pipe 12 and the outlet pipe 13 are connected through the flow channel 2 on the valve plate 11. The filter mechanism 3 is installed on the end of the outlet pipe 13 away from the valve plate 11. The valve plate 11 has an installation opening. In this embodiment, two mounting holes 7 are provided, respectively located at both ends of the valve plate 11 along its length. The mounting holes 7 are used to insert bolts for fixing. The valve plate 11 facilitates the installation and fixing of the tube body 1 on the polishing equipment, and facilitates the control of the outlet position of the polishing liquid. A connecting plate 8 is detachably installed on the valve plate 11. The connecting plate 8 is detachably installed on the valve plate 11 through the mounting bolts in the mounting holes 7. The other end of the connecting plate 8 is connected to the polishing equipment. The valve plate 11 is installed on the polishing equipment through connecting plates 8 of various shapes and sizes, thereby adjusting the outlet position of the polishing liquid.

[0033] The implementation principle of this application embodiment is as follows: Select a suitable connecting plate 8 according to the installation requirements, install the pipe body 1 on the polishing equipment through the connecting plate 8, and make the outlet of the liquid outlet pipe 13 of the pipe body 1 face the area where polishing liquid is needed. Then, put the filter tube sleeve 31 with the filter screen 32 on the outlet of the liquid outlet pipe 13, and reinforce the filter tube sleeve 31 on the outlet pipe 13 with the reinforcing bolt 6. Connect the pipe body 1 and the polishing liquid source by connecting the pipe to the liquid inlet pipe 12 of the pipe body 1. When the polishing equipment is polishing, the polishing liquid is delivered to the polishing area through the pipe body 1 to improve the polishing effect. When the polishing liquid forms crystals in the pipe body 1, the filter screen 32 will filter and block the crystals to flow to the polishing area with the polishing liquid.
