Description

Technical Field

[0001] This application relates to the field of filtration equipment technology, specifically to a filtration device for rinsing water after aluminum alloy oxidation. Background Technology

[0002] In order to overcome the shortcomings of aluminum alloy surface properties and extend its service life, aluminum alloy is usually anodized. However, the material after anodizing must undergo multiple rinsing stages, which consumes a lot of water and the water after rinsing contains a large number of impurities.

[0003] An existing patent (publication number: CN219462635U) discloses a filtration device for rinsing water after aluminum alloy oxidation, including a filter box. A filter screen is fixedly installed inside the filter box, and a device housing is fixedly installed on the right side of the filter box. This filtration device works by starting a water pump to deliver water from the tank through an inlet pipe to a telescopic hose. The telescopic hose then delivers water through a second water pipe to a first water pipe, which then sprays the water out through a high-pressure nozzle. The high-pressure nozzle sprays the water upwards to flush out impurities inside the filter screen. Then, a motor is started to drive a rotating rod. The rotating rod, through a convex rod, drives a circular groove to move left and right. The circular groove drives the first water pipe, causing the high-pressure nozzle to move to the left. Simultaneously, the circular groove drives a cleaning rod. The cleaning rod, through a second telescopic rod, drives a scraper to adhere to the surface of the filter screen, pushing the flushed impurities to the left. When the cleaning rod moves to the left, a second spring drives the scraper to move downwards, ensuring the scraper remains in contact with the filter screen surface, pushing the flushed impurities to the left.

[0004] The aforementioned device uses a second telescopic rod to drive a scraper to adhere to the surface of the filter screen, pushing the flushed impurities to the left. When the cleaning rod moves to the left, the second spring drives the scraper downward, ensuring that the scraper remains in contact with the surface of the filter screen and pushes the flushed impurities to the left. However, the impurities accumulate on the left end of the filter screen, occupying the filter mesh. Furthermore, as the water to be filtered continuously flows in, the accumulated impurities are easily dispersed, affecting the filtration efficiency of the filter screen. This necessitates frequent maintenance and cleaning, which is quite inconvenient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a filtration device for rinsing water after aluminum alloy oxidation, which has advantages such as automatic waste discharge and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a filtration device for rinsing water after aluminum alloy oxidation, comprising a tank body, wherein a rinsing chamber, a filtration chamber and a waste storage chamber are arranged sequentially from right to left inside the tank body;

[0007] The waste storage bin has an upwardly inclined waste discharge channel on its inner wall near the filter bin. Filter screens are fixedly connected between the left and right inner walls of the filter bin. Belts are installed on both the front and rear inner walls of the filter bin. Both belts and the filter screens are inclined with the left side higher than the right side. The tops of the two belts are located inside the waste discharge channel, and the bottoms of the two belts are parallel to the inner bottom wall of the waste discharge channel and the upper surface of the filter screen. A set of scrapers arranged at equal intervals are fixedly connected to the outer surfaces of the two belts.

[0008] Furthermore, a drive shaft is rotatably connected between the front and rear inner walls of the waste discharge channel and between the front and rear inner walls of the bottom end of the waste storage bin. Two drive wheels are fixedly connected to the outer surface of each drive shaft. The two drive wheels located at the front and the two drive wheels located at the left rear are connected by belt drives close to them.

[0009] Through the above scheme, the transmission system consisting of the drive wheel and belt drives the scraper above the filter screen to move continuously, thereby realizing the function of pushing impurities.

[0010] Furthermore, one end of the drive shaft located at the bottom is fixedly connected to the external motor output end.

[0011] With the above scheme, when the motor starts, it drives the belt system through the bottom drive shaft, so that the scraper pushes the impurities from right to left along the surface of the filter screen.

[0012] Furthermore, a cleaning shaft is rotatably connected between the front and rear inner walls of the waste storage bin, and a cleaning roller is fixedly connected to the outer surface of the cleaning shaft. The cleaning roller abuts against the scraper adjacent to it. Gears are fixedly connected to one end of the cleaning shaft and one end of the uppermost drive shaft. The two gears are meshed together, and the cleaning roller is located above the top of the two belts.

[0013] With the above solution, the belt can drive the scraper to move during rotation, and the drive shaft drives the cleaning roller to rotate through gear transmission, which can clean the returning scraper and prevent the scraper from being covered with impurities.

[0014] Furthermore, a door panel is hinged to one side of the waste storage bin.

[0015] The above solution allows for the periodic cleaning of deposited impurities in the waste storage bin by opening and closing the door panel, and sealing strips are installed on the edge of the door panel to prevent wastewater leakage.

[0016] Furthermore, a first pump body is fixedly installed on the outer surface of the pool body. The input end of the first pump body is fixedly connected to the rinsing chamber, and the output end of the first pump body is fixedly connected to the filter chamber. The output end of the first pump body is located above the filter screen.

[0017] The above scheme allows the rinsing water to be pumped into the filter chamber above the filter chamber for filtration via the first pump.

[0018] Furthermore, a second pump body is fixedly installed on the outer surface of the pool body. The input end of the second pump body is fixedly connected to the filter chamber, and a precision filter body is provided at the output end of the second pump body. The output end of the second pump body is fixedly connected to the liquid inlet of the precision filter body, and the output end of the precision filter body is fixedly connected to the rinsing chamber.

[0019] The above solution enables the precision filter body to filter the rinse water after the initial filtration, achieving the goal of recycling.

[0020] Furthermore, a drain grid is fixedly installed on the inner wall of the top of the filter chamber.

[0021] The above solution, with the installation of a drain grid, facilitates the placement of rinsed aluminum alloy products for draining and air drying.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This aluminum alloy post-oxidation rinsing water filtration device features an inclined combination design of a waste storage chamber and a waste discharge channel, coupled with a belt-driven continuous scraper mechanism. This enables the directional pushing of impurities from right to left onto the filter screen surface. The scraper maintains dynamic contact with the filter screen surface throughout its movement, ensuring that impurities are continuously transferred to an independent waste storage area. This effectively avoids the problem of reduced filtration area caused by impurities accumulating at the filter screen end in traditional devices. Through a gear linkage device between the drive shaft and the cleaning roller, after the scraper completes the impurity pushing, flexible cleaning strips embedded on the surface of the cleaning roller on the scraper's return path can immediately peel off residual impurities, preventing impurities from returning to the filter screen area with the scraper and causing secondary pollution. This ensures the continuous filtration efficiency of the filter screen. The first pump body achieves primary solid-liquid separation of impurity-containing wastewater into the filtration chamber, while the second pump body, in conjunction with a precision filter, completes deep purification, ensuring that the quality of the recycled water meets the requirements of the rinsing process and significantly improving the water resource recycling rate.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of an aluminum alloy oxidation rinse water filtration device includes a tank body 1. Inside the tank body 1, from right to left, are arranged a rinsing chamber 2, a filtration chamber 3, and a waste storage chamber 4. The waste storage chamber 4 has an upwardly inclined waste discharge channel 5 near the inner wall of the filtration chamber 3. A filter screen 6 is fixedly connected between the left and right inner walls of the filtration chamber 3. Belts 7 are installed on both the front and rear inner walls of the filtration chamber 3. Both belts 7 and the filter screen 6 are inclined from left to right, with the tops of both belts 7 located inside the waste discharge channel 5, and the bottoms of both belts 7 connected to the inner bottom wall of the waste discharge channel 5 and the upper surface of the filter screen 6. The surfaces are parallel, and a set of equally spaced scrapers 8 are fixedly connected to the outer surfaces of the two belts 7. The scrapers 8 can be moved by the belt 7. The scrapers 8 can continuously push the impurities attached to the upper surface of the filter screen 6, so that the impurities fall into the waste storage bin 4 through the waste discharge channel 5. This effectively avoids the accumulation of impurities on the surface of the filter screen 6, ensures the filtration efficiency of the filter screen 6, and facilitates the handling by workers. A drain grid 18 is fixedly installed on the inner wall of the top of the filter bin 3. The drain grid 18 makes it easy to place the rinsed aluminum alloy products for draining and drying.

[0032] Please see Figure 1 , Figure 2 and Figure 4A drive shaft 9 is rotatably connected between the front and rear inner walls of the waste discharge channel 5 and between the front and rear inner walls of the bottom end of the waste storage bin 4. Two drive wheels 10 are fixedly connected to the outer surface of each drive shaft 9. The two drive wheels 10 located at the front and the two drive wheels 10 located at the left rear are connected by a belt 7 close to them. The drive system consisting of the drive wheels 10 and the belt 7 drives the scraper 8 above the filter screen 6 to move continuously, realizing the impurity pushing function. One end of the drive shaft 9 located at the bottom end is fixedly connected to the output end of the motor. When the motor starts, it drives the belt 7 system through the bottom drive shaft 9, so that the scraper 8 pushes the impurities from right to left along the surface of the filter screen 6.

[0033] Please see Figure 1 , Figure 2 and Figure 3 A cleaning shaft 11 is rotatably connected between the front and rear inner walls of the waste storage bin 4. A cleaning roller 12 is fixedly connected to the outer surface of the cleaning shaft 11. The cleaning roller 12 abuts against the scraper 8 that is close to it. A gear 13 is fixedly connected to one end of the cleaning shaft 11 and one end of the uppermost drive shaft 9. The two gears 13 are meshed together. The cleaning roller 12 is located above the top of the two belts 7. During the rotation of the belts 7, the scraper 8 can be moved. At the same time, the drive shaft 9 drives the cleaning roller 12 to rotate through the gear 13, which can clean the returning scraper 8 and prevent the scraper 8 from being covered with impurities. A door panel 14 is hinged to one side of the waste storage bin 4. The opening and closing of the door panel 14 realizes the periodic cleaning of the impurities deposited in the waste storage bin 4. A sealing strip is set on the edge of the door panel 14 to prevent wastewater leakage.

[0034] Please see Figure 1 , Figure 2 and Figure 3A first pump body 15 is fixedly installed on the outer surface of the tank body 1. The input end of the first pump body 15 is fixedly connected to the rinsing chamber 2, and the output end of the first pump body 15 is fixedly connected to the filter chamber 3. The output end of the first pump body 15 is located above the filter screen 6. Through the first pump body 15, rinsing water can be pumped into the filter chamber 3 for filtration. A second pump body 16 is fixedly installed on the outer surface of the tank body 1. The input end of the second pump body 16 is fixedly connected to the filter chamber 3, and the output end of the second pump body 16 is provided with a precision filter body 17. The output end of the second pump body 16 is fixedly connected to the liquid inlet of the precision filter body 17. The output end is fixedly connected to the rinsing chamber 2. The outer shell of the precision filter cylinder is generally made of stainless steel. The internal tubular filter elements are PP melt-blown, wire-burned, pleated, titanium filter elements, activated carbon filter elements, etc. Different filter elements are selected according to different filter media and design processes to meet the requirements of effluent water quality. It is used for solid-liquid separation of various suspensions, filtration of pharmaceutical solutions with high environmental requirements and high filtration accuracy. It has a wide range of applications and is suitable for industrial fields such as pharmaceuticals, food, chemicals, environmental protection, and water treatment. The precision filter body 17 can filter the rinse water after the initial filtration to achieve the purpose of recycling.

[0035] The working principle of the above embodiment is as follows: The first pump 15 is started to draw the wastewater containing impurities from the rinsing chamber 2 to the top of the filter chamber 3. Under the action of gravity, the wastewater vertically seeps down to the surface of the filter screen 6. The filter screen 6 intercepts solid impurities such as metal fragments and oxide film residues in the wastewater, completing the primary solid-liquid separation. The motor drives the bottom drive shaft 9 to rotate, which drives two belts 7 to rotate synchronously through the drive wheel 10. The equidistant scrapers 8 on the outer surface of the belts 7 move with the belts 7, pushing the impurities on the surface of the filter screen 6. The impurities are continuously pushed to the left end of the filter screen 6 and slide into the waste storage chamber 4 along the waste discharge channel 5, preventing impurities from accumulating locally on the filter screen 6 and clogging the mesh. When the scrapers 8 have finished pushing the impurities, they move with the belts 7 to the top return path. The cleaning roller 12 is driven by the gear 13 transmission mechanism. The roller begins to rotate, and the flexible silicone strip embedded on the surface of the cleaning roller 12 contacts the surface of the scraper 8. Through physical friction, it removes residual impurities attached to the surface of the scraper 8, preventing impurities from returning to the filter screen 6 area with the scraper 8 and causing secondary pollution. This ensures the continuous filtration efficiency of the filter screen 6. The wastewater that has been initially filtered by the filter screen 6 enters the bottom of the filter chamber 3, and the second pump body 16 draws it to the precision filter body 17, where it deeply intercepts particulate impurities in the wastewater. The purified water flows back to the rinsing chamber 2, realizing a closed-loop water resource cycle. The impurities deposited in the waste storage chamber 4 are cleaned periodically through the door panel 14. The drain grid 18 set on the top of the filter chamber facilitates the placement of the rinsed aluminum alloy workpieces for draining. The residual liquid on the surface of the workpiece flows back to the filter chamber 3 along the grid holes, reducing water waste.
