Description

Technical Field

[0001] This utility model relates to the technical field of sand polishing liquid filter machines, and in particular to a cleaning, pressurizing and flow guiding structure for a sand polishing liquid filter machine. Background Technology

[0002] With technological advancements, most polishing objects are now high-strength metals (such as titanium), necessitating the use of chemical polishing slurries. Since chemical polishing slurries tend to solidify and crystallize easily, timely and effective filtration is required for recycling them. This is crucial to reduce impurities and ensure reuse. Furthermore, the specific gravity and concentration of the chemical polishing slurry must be carefully considered during recycling to guarantee its proper return to the recovery tank. However, in traditional polishing slurry recovery paths without additional pressurization, the high specific gravity and concentration of the chemical polishing slurry can lead to slow flow and blockages. Utility Model Content

This structure can significantly improve the discharge speed of the sand polishing fluid and is suitable for the recycling of sand polishing fluids that are easy to crystallize and solidify and have high specific gravity and high concentration. It can effectively filter out impurities in the sand polishing fluid, ensure its filtration efficiency, and improve the recycling efficiency.

[0049] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0050] like Figures 1-6 As shown, this utility model provides a cleaning, pressurizing, and flow guiding structure for a sand polishing liquid filter. It mainly consists of a base 11 and a centrifugal filter cartridge 21 disposed inside the base 11, wherein:

[0051] The seat 11 has an interior chamber 12 with an upward-facing opening 121. The chamber 12 has a downward-facing bottom surface 122, and a flow channel 13 is recessed in the bottom surface 122, connecting to the outside of the chamber 12. The flow channel 13 is curved and has a downward-sloping surface 131 that gradually slopes to connect to the outside of the chamber 12. An outlet pipe 14 is connected to the outlet end of the flow channel 13 outside the seat 11. The outlet pipe 14 has an inlet end 141 connected to the flow channel 13, and a first branch end 142 and a second branch end 143 connected to the inlet end 141. The first branch end 142 is a continuously upward-bent tube shape. The height of the first branch end 142 is greater than the height of the inlet end 141 and the second branch end 143. The first branch end 142 forms a sand polishing liquid recovery channel, while the second branch end 143 forms a cleaning water discharge channel. The inlet end 141 is provided with a one-way valve 15 that only allows the liquid in the guide channel 13 to flow into the outlet pipe 14 in one direction to avoid backflow of the discharged liquid. A switching valve 16 is provided at the junction of the first branch end 142 and the second branch end 143. By controlling the switching valve 16, the liquid discharged into the outlet pipe 14 can be selectively discharged outward through either the first branch end 142 or the second branch end 143.

[0052] Furthermore, a funnel-shaped top cover 17 is provided at the opening 121 of the chamber 12. The top cover 17 has an inlet 171 that is directly opposite the center of the chamber 12 and tapers downwards. A drive device 18 is provided on one side of the base 11. The drive device 18 has a rotating shaft 181 that passes through the bottom surface 122 of the chamber 12 and extends into the chamber 12. In this embodiment, the drive device 18 is composed of a motor disposed on the outer periphery of the base 11. A pulley assembly 183 is connected between the output shaft 182 of the drive device 18 and the end of the rotating shaft 181, so that the drive device 18 can drive its rotating shaft 181 to rotate when it is running.

[0053] The centrifugal filter cartridge 21 is rotatably housed in the chamber 12, and the inlet 171 of the top cover 17 is aligned with the center of the centrifugal filter cartridge 21. The centrifugal filter cartridge 21 is a multi-layer filter cartridge structure consisting of multiple cylindrical filter cartridges. A disc-shaped turntable 22 is detachably connected to the bottom of the centrifugal filter cartridge 21. The turntable 22 has a set of holes 221 at its center, allowing the centrifugal filter cartridge 21 to be mounted on the rotating shaft 181 through the holes 221. Multiple radially arranged blades 23 are attached to the end face of the turntable 22 facing the bottom surface 122 of the chamber 12. In this embodiment, each blade 23 is fixed at intervals along the periphery of the turntable 22 on the downward-facing end face of the turntable 22, and each blade 23 has a downward-sloping inclined section 231. When the rotating shaft 181 drives the turntable 22 and the centrifugal filter cartridge 21 to rotate, the sand polishing liquid that is filtered and thrown out by the centrifugal filter cartridge 21 and flows down the periphery of the chamber 12 to the bottom surface 122 can be further pressurized by the pushing action generated by the rotation of each blade 23 and discharged into the guide channel 13. Then, by controlling the switching valve 16, the filtered sand polishing liquid can be discharged outward from the first branch end 142.

[0054] In practical use, the present invention, composed of the above-described structure, such as... Figure 5 , 6As shown, by placing a sand polishing liquid recovery pipeline 31 above the top cover 17, the unfiltered sand polishing liquid after use can be injected downwards into the centrifugal filter cartridge 21 through the injection port 171 of the top cover 17 for layer-by-layer grading filtration, and the filtered sand polishing liquid can be discharged outwards through the first branch end 142 by controlling the switching valve 16. Furthermore, in practical applications, a mesh plate 19 can be installed above the inlet 171 to perform preliminary filtration of the polishing liquid. Under the centrifugal force generated by the rotating shaft 181 simultaneously rotating the turntable 22 and the centrifugal filter cartridge 21, the polishing liquid in the centrifugal filter cartridge 21 can be agitated and filtered layer by layer. This not only effectively removes impurities from the polishing liquid, facilitating its recycling and reuse, but also further impurities from the polishing liquid that are filtered and ejected layer by layer by the centrifugal filter cartridge 21 and flow down the periphery of the chamber 12 to the bottom surface 122. These impurities are further filtered by the pushing action generated by the rotation of the inclined sections 231 of each blade 23. Pressurized discharge into the guide channel 13 not only significantly increases the discharge speed of the polishing slurry, but is also suitable for the recycling of polishing slurries that are prone to crystallization and solidification and have high specific gravity and high concentration. In addition, with the additional pressurization function provided by each blade 23, the outlet end of the first branch end 142 of the outlet pipe 14 can be set at a high position, which can ensure that the discharged polishing slurry can be injected from above a polishing slurry recycling tank 41. This effectively solves the problems of easy blockage when the polishing slurry is injected from the bottom of the polishing slurry recycling tank 41 due to its high specific gravity or concentration in traditional recycling operations, as well as the low recycling efficiency caused by difficulty in injection.

[0055] When cleaning the centrifuge filter cartridge 21, the user only needs to remove the centrifuge filter cartridge 21 along with its rotating disc 22 from the rotating shaft 181. Then, clean water can be injected into the chamber 12 through a water inlet pipe 51 located above the opening 121 for cleaning. During the cleaning process, if... Figure 7 As shown, by controlling the switching valve 16, the wastewater after cleaning can be discharged outward through the second branch end 143, thereby achieving the purpose of diverting the recovered sand polishing liquid and the wastewater after cleaning, which is beneficial for subsequent cleaning.

[0056] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
