Description

Technical Field

[0001] This utility model relates to the field of product polishing technology, specifically to an anti-clogging fluid polishing medium treatment device. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical actions 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. Polishing does not improve the dimensional or geometric accuracy of the workpiece; rather, it aims to achieve a smooth surface or a mirror-like finish. Sometimes it is also used to eliminate shine (matte finish). Polishing wheels are typically used as the polishing tool. Polishing wheels are generally made of multiple layers of canvas, felt, or leather, clamped on both sides by metal discs, and their rims are coated with a polishing compound consisting of a uniform mixture of micro-powdered abrasive particles and grease.

[0003] Fluid polishing is a precision machining technique that utilizes a fluid medium to process workpiece surfaces. It is widely used in metal processing, optical component manufacturing, electronic component production, and medical device manufacturing. Through the flow and friction of the fluid medium, fluid polishing effectively removes minute imperfections on the workpiece surface, improving surface finish and precision. As a highly efficient, uniform, and refined surface treatment technology, fluid polishing has broad application prospects in multiple fields. With technological advancements, fluid polishing will achieve greater breakthroughs in nanometer-level precision, environmental friendliness, and intelligent control, providing higher-quality surface treatment solutions for modern manufacturing.

[0004] In current fluid polishing devices, the liquid polishing medium is usually a mixture of fluid and abrasive particles in a certain proportion. This fluid polishing medium is finally sprayed out from the spray gun. The spray gun has a precise structure and a small orifice. The abrasive particles in the fluid polishing medium can easily clog the spray gun. Cleaning the spray gun clog is costly, time-consuming and labor-intensive. Existing fluid polishing devices cannot separate coarse abrasive particles before they enter the spray gun, which increases the risk of clogging. If only a filter structure is used, the filter structure will also face the risk of clogging after a long time. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging fluid polishing medium treatment device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A clog-resistant fluid polishing media processing device includes a feed pipe for conveying fluid polishing media, a filter assembly for preventing clogging on the feed pipe, the filter assembly including a filter element installed inside the feed pipe, and a backwashing assembly on the feed pipe.

[0008] In the above technical solution, the filter assembly is installed on the feed pipe. The filter assembly can filter the fluid polishing medium inside the feed pipe, separate the coarse abrasive particles in the fluid polishing medium, and prevent larger abrasive particles from entering the spray gun. The backwashing assembly can backwash the filter assembly to prevent the filter assembly from clogging.

[0009] A further improvement of the present invention is that the filter element includes a filter plate, which is arranged in a conical shape.

[0010] The above technical solution features a tapered filter plate, which increases the filtration area and extends the filter plate's service life.

[0011] A further improvement of the present invention is that the backwashing assembly includes a water tank for storing the backwashing liquid, a water pipe connected to the water tank, a water pump installed on the water pipe, and a nozzle. The nozzle is positioned facing the filter plate, and a protective component is provided on the outside of the nozzle.

[0012] Using the above technical solution, the backwashing component can backwash the filter plate, and the water pump can spray the flushing liquid in the water tank onto the filter plate through the nozzle, which can flush down the coarse abrasive particles on the filter plate and prevent the filter plate from being blocked by coarse abrasive particles after long-term use.

[0013] A further improvement of the present invention is that the protective component includes a collar installed at the end of the nozzle, and the inner side of the collar is provided with a plurality of rubber sheets arranged in a circular pattern, the plurality of rubber sheets being densely laid out in a circle.

[0014] Using the above technical solution, the sleeve is snapped onto the end of the nozzle, and the rubber sheet can cover the liquid outlet end of the nozzle, which can unidirectionally block the nozzle without affecting the normal spraying of the flushing liquid and can protect the nozzle.

[0015] A further improvement of the present invention is that: the feed pipe is provided with a discharge pipe for discharging the coarse particles washed down by backwashing, the feed pipe is provided with valve one, and the discharge pipe is provided with valve two.

[0016] The above technical solution is adopted in which the discharge pipe is connected to the feed pipe. Valve 1 can close the feed pipe and valve 2 can close the discharge pipe, which can facilitate the switching between normal use and backwashing state, facilitate the cleaning of the filter plate, and avoid the backwashing process from affecting the entire feed pipe.

[0017] A further improvement of the present invention is that: the feed pipe is provided with a guide plate that cooperates with the discharge pipe, the guide plate is inclined, and there is a gap between the guide plate and the discharge pipe.

[0018] Using the above technical solution, the guide plate can guide the fluid polishing medium flowing above the discharge pipe, avoiding the normal flow of the fluid polishing medium due to the discharge pipe. The gap is located on the side of the guide plate near the filter plate, which facilitates the coarse abrasive particles to enter the discharge pipe and be collected.

[0019] A further improvement of this utility model is that a guide plate is provided on the inner wall of the feeding pipe.

[0020] By adopting the above technical solution, the guide plate is fixedly connected to the feed pipe, which can further protect the nozzle and reduce the wear of the nozzle caused by the fluid polishing medium.

[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0022] 1. This utility model provides a non-clogging fluid polishing medium treatment device, which is equipped with a filter plate in the feed pipe. The filter plate can filter and separate coarse abrasive particles in the flowing fluid medium, and can prevent coarse abrasive particles from entering the spray gun and causing clogging.

[0023] 2. This utility model provides a device for treating anti-clogging fluid polishing media. A backwashing component is set near the filter plate. The backwashing component can backwash the filter plate, which can prevent coarse abrasive particles from clogging the filter plate and improve the service life of the filter plate.

[0024] This invention provides a device for treating anti-clogging fluid polishing media. By setting up a filter plate and a backwashing component, the filter plate can filter and separate the flowing fluid polishing media, separating coarse abrasive particles. The backwashing component can flush down the coarse abrasive particles retained on the filter plate. The separated coarse abrasive particles and the backwashed coarse abrasive particles will enter the discharge pipe, eliminating the need for frequent filter plate replacement.

[0033] The present invention will be further described in detail below with reference to embodiments:

[0034] Example 1

[0035] like Figure 1-6 As shown, this utility model provides an anti-clogging fluid polishing medium processing device, including a feed pipe 1 for conveying fluid polishing medium. The feed pipe 1 is provided with a filter assembly for preventing clogging. The filter assembly includes a filter element installed inside the feed pipe 1. The feed pipe 1 is provided with a backwashing assembly. The filter element includes a filter plate 2, which is conical. The backwashing assembly includes a water tank 3 for storing rinsing liquid, a water pipe 4 connected to the water tank 3, a water pump 5 installed on the water pipe 4, and a nozzle 6. The nozzle 6 is positioned facing the filter plate 2, and a protective assembly is provided on the outside of the nozzle 6.

[0036] In this embodiment, the inlet end of the feed pipe 1 is connected to the outlet end of the fluid medium in the fluid polishing machine, and the outlet end of the feed pipe 1 is connected to the inlet end of the spray gun. The fluid polishing medium is preferably a polishing slurry containing abrasive particles. The filter assembly can filter the fluid polishing medium flowing inside the feed pipe 1 to prevent excessively large abrasive particles from clogging the feed pipe 1. The filter element is a filter plate 2 that is snapped into the inside of the feed pipe 1. The filter plate 2 is preferably made of high-strength stainless steel. When the fluid polishing medium flows through the filter plate 2, it can be filtered, and excessively large fluid polishing media can be separated into the filter. On one side of plate 2, water tank 3 stores rinsing fluid. The rinsing fluid can be a polishing fluid without added abrasive particles. Water pipe 4 is connected to water tank 3. Water pump 5 can be purchased directly from the market. Nozzle 6 is fixedly installed on the inner wall of feed pipe 1. Nozzle 6 is set towards the filter screen. Water pump 5 can make the rinsing fluid in water tank 3 flow through water pipe 4 and spray it onto filter plate 2 from nozzle 6. The direction of the rinsing fluid sprayed from nozzle 6 is opposite to the feeding direction of the fluid polishing medium. It can backwash filter plate 2, flush down the abrasive particles retained on filter plate 2, and prevent the abrasive particles on filter plate 2 from clogging the filter holes.

[0037] like Figure 1-6 As shown, in this embodiment, preferably, the feed pipe 1 is provided with a discharge pipe 9 for discharging the coarse particles washed down by backwashing. The feed pipe 1 is provided with valve 10, and the discharge pipe 9 is provided with valve 21. The discharge pipe 9 is connected to the feed pipe 1 and is connected to the feed direction of the filter plate 2. Both valve 10 and valve 21 are commonly used one-way valves on the market. Valve 10 is installed on the feed pipe 1, and valve 21 is installed on the discharge pipe 9. When polishing is required, valve 10 is opened and valve 21 is closed. The discharge pipe 9 above valve 21 is filled with fluid polishing medium. The subsequent fluid polishing medium will pass through the filter screen for normal filtration. When backwashing is required, valve 10 is closed and valve 21 is opened. The washed-down coarse abrasive particles will enter the discharge pipe 9 for storage. Subsequently, as the amount of coarse abrasive particles in the discharge pipe 9 increases, the polishing liquid inside will also flow back into the feed pipe 1.

[0038] like Figure 1-6 As shown, preferably, the feed pipe 1 is provided with a guide plate 12 that cooperates with the discharge pipe 9. The guide plate 12 is inclined and there is a gap between the guide plate 12 and the discharge pipe 9. The guide plate 12 is fixed to the inner wall of the feed pipe 1 and is inclined toward the filter plate 2. There is a gap between the end of the guide plate 12 near the filter plate 2 and the discharge pipe 9. During the flow of the fluid polishing medium, it will be guided by the guide plate 12 and the polishing liquid will not directly enter the discharge pipe 9. The polishing liquid will slowly flow back into the discharge pipe 9 during the filtration process of the filter plate 2. This arrangement can reduce the influence of the discharge pipe 9 on the flow rate of the fluid polishing medium.

[0039] Example 2

[0040] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the protective component includes a collar 7 installed at the end of the nozzle 6, and the inner side of the collar 7 is provided with a plurality of rubber sheets 8 arranged in a circular pattern, and the plurality of rubber sheets 8 are densely laid in a circle.

[0041] In this embodiment, the sleeve is snapped onto the end of the nozzle 6, and there are multiple rubber sheets 8. These multiple rubber sheets 8 can cover the end of the nozzle 6. During normal polishing, the liquid cooling medium will flow on the surface of the multiple rubber sheets 8 and will not directly contact the nozzle 6, thus preventing the abrasive particles in the liquid cooling medium from clogging the nozzle 6. During backwashing, the rinsing liquid can push away the multiple rubber sheets 8 and then spray onto the filter plate 2, which can protect the nozzle 6 and prevent damage.

[0042] Example 3

[0043] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a guide plate 13 is provided on the inner wall of the feeding pipe 1.

[0044] In this embodiment, the second guide plate 13 is fixed to the top of the inner wall of the feed pipe 1. The second guide plate 13 is inclined and can shield the nozzle 6 and guide the liquid polishing medium near the nozzle 6, directing the fluid to the middle, preventing the liquid polishing medium from rushing onto the nozzle 6 at a high speed, and further reducing the wear of the nozzle 6.

[0045] Example 4

[0046] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the inner wall of the feed pipe 1 is provided with a groove, and the end of the nozzle 6 is located inside the groove.

[0047] In this embodiment, the nozzle 6 and its protective components are located inside the groove, which can further improve the protective effect of the nozzle 6 and prevent wear of the nozzle 6.

[0048] The working principle of this anti-clogging fluid polishing media treatment device will be explained in detail below.

[0049] like Figure 1-6As shown, during polishing, valve 11 is first closed and valve 10 is opened. Then, liquid polishing medium is pumped into the feed pipe 1. After being guided by guide plate 12, the liquid polishing medium enters the filter plate 2. The filter plate 2 separates larger abrasive particles from the flowing fluid polishing medium, preventing these particles from clogging the filter plate 2 and the spray gun. During this process, larger abrasive particles are blocked by the filter plate 2. As the number of larger abrasive particles increases, they gradually enter the discharge pipe 9. When the flow rate of the liquid polishing medium through the filter plate 2 decreases, the filter plate 2 is backwashed. During backwashing, valve 10 is closed and valve 21 is opened. Then, the flushing liquid is sprayed from the nozzle 6 along the water pipe 4 by the water pump 5. When the nozzle 6 sprays out, the flushing liquid first pushes away multiple rubber sheets 8 and then flows onto the filter plate 2. Since the direction of the flushing liquid spray is opposite to the direction of the liquid polishing medium, large abrasive particles will detach from the filter plate 2 and enter the discharge pipe 9 along the gap between the guide plate 12 and the discharge pipe 9, and then be discharged from the discharge pipe 9.

[0050] 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.
