[0035] To enable those skilled in the art to better understand the technical solutions of this application, 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0036] Please refer to the following: Figures 1 to 5 This embodiment provides a disc-type microfiltration machine, including a housing 100, a rotating disc filter 200, a scraper 300, and a drive device 400. The housing 100 is provided with a drain port 130. The rotating disc filter 200 is rotatably mounted on the housing 100. The scraper 300 is located above the rotating disc filter 200 and is used to scrape the impurities filtered out on the rotating disc filter 200. The scraper 300 is positioned towards the drain port 130. The drive device 400 is drivenly connected to the rotating disc filter 200 to drive the rotating disc filter 200 to rotate.
[0037] As can be seen, the disc-type microfilter in this embodiment filters fishpond wastewater through a rotating disc filter 200. A scraper 300 is provided above the rotating disc filter 200 so that when the driving device 400 drives the rotating disc filter 200 to rotate, the scraper 300 scrapes the impurities filtered out on the rotating disc filter 200, thereby preventing impurities from accumulating and clogging the filter holes of the rotating disc filter 200 and affecting the filtration effect. Furthermore, a circulating rotation filtration method is adopted, allowing the rotating disc filter 200 to rotate and perform dynamic continuous filtration. This ensures that the area on the rotating disc filter 200 that has been cleaned by the scraper 300 rotates again to receive fishpond wastewater for continuous filtration. In this way, a portion of the area on the rotating disc filter 200 is cleaned as much as possible each time it receives fishpond wastewater, thereby ensuring filtration effect and efficiency, facilitating use, and improving the applicability and convenience of the product. The microfilter has a simple and ingenious structural design, small size, does not occupy much space, and is easy to use.
[0038] In this embodiment, a partition 110 is provided inside the housing 100. The partition 110 can be integrally formed with the housing 100, or the partition 110 can be horizontally installed inside the housing 100 by screws. The partition 110 divides the interior of the housing 100 into an installation chamber and a clean water tank from top to bottom. The partition 110 has a connecting notch 111 to allow the installation chamber to communicate with the clean water tank. The rotary filter screen 200 is rotatably installed on the partition 110. The connecting notch 111 is located below the rotary filter screen 200. In this embodiment, the shape of the connecting notch 111 is not limited. The connecting notch 111 allows the clean water filtered by the rotary filter screen 200 to flow into the clean water tank. The clean water tank can be provided with a drain outlet to allow the clean water in the clean water tank to flow back into the fish pond for use.
[0039] Specifically, the scraper 300 is rotatably mounted on the housing 100 so that the scraper 300 can rotate away from the rotary filter screen 200. This arrangement allows the rotary filter screen 200 to be flipped open from above by rotating the scraper 300, facilitating cleaning or maintenance and replacement of the rotary filter screen 200. The top cover of the housing 100 is removable and can be opened.
[0040] Furthermore, a connecting plate 150 is provided inside the housing 100. At least one hinge 151 is provided between the upper surface of the scraper 300 and the upper surface of the connecting plate 150 so that the scraper 300 and the connecting plate 150 can be kept approximately flush through the hinge 151. The connecting plate 150 is located above the partition 110. The hinge 151 is an existing component and will not be described in detail here.
[0041] In this embodiment, the rotary filter 200 includes a rotating ring 210 and a filter screen 220. The rotating ring 210 is driven and connected to the driving device 400. The filter screen 220 is disposed on the rotating ring 210 and can be installed on the rotating ring 210 by screws. The filter screen 220 is circular in shape so that the filter screen 220 of the rotary filter 200 can be driven by the driving device 400 to rotate and circulate for filtration, thereby effectively improving the filtration efficiency.
[0042] Specifically, the housing 100 is provided with a support plate 140, which is located below the filter screen 220. The scraper 300 and the support plate 140 are arranged vertically opposite each other. The length extension directions of the support plate 140 and the scraper 300 are approximately the same. With this arrangement, the support plate 140 can support the filter screen 220, preventing the filter screen 220 from being pressed down and bulging due to the scraper 300 scraping the impurities filtered out of the filter screen 220. This effectively prevents the filter screen 220 from being damaged and improves the reliability and practicality of the microfilter.
[0043] The housing 100 is equipped with a sewage pipe 120, which is located above the rotary filter screen 200. The sewage pipe 120 is used to connect to external equipment and transport fish pond sewage to the rotary filter screen 200 for filtration. The sewage outlet 121 and the drain outlet 130 of the sewage pipe 120 are located at the two ends of the scraper 300, respectively. The scraper 300 is arranged to extend roughly along the radial direction of the rotary filter screen 200 so that impurities flow along the scraper 300 into the drain outlet 130 and are discharged to the outside. The drain outlet 130 is arranged near the edge of the rotary filter screen 200. The opening size of the drain outlet 130 can be designed to be larger. The drain outlet 130 is arranged corresponding to the end of the scraper 300 to avoid impurities after filtration from falling onto the partition 110 and causing pollution.
[0044] In this embodiment, the inner circumferential surface of the rotating ring 210 is provided with an annular groove 211, and the housing 100 is provided with a support member 112, so that the edge of the support member 112 is at least partially movably embedded in the annular groove 211 so as to rotate and install the rotating screen 200. In this way, the rotating ring 210 can be rotatably installed.
[0045] The rotating ring 210 is rotatably mounted on the partition 110 and is located in the installation chamber. The support member 112 includes a support rod and an end cap. The end cap is disc-shaped. The support rod is set on the partition 110 and the end cap is set on the top of the support rod so that the edge of the end cap can be movably embedded in the annular groove 211 of the rotating ring 210 to achieve rotatable installation. There are multiple support members 112, and the multiple support members 112 are spaced apart circumferentially so that the end caps of the multiple support members 112 can be movably embedded in the annular groove 211 of the rotating ring 210 to support the rotating ring 210.
[0046] Specifically, the drive device 400 includes a motor 410, a gear 420, and a gear ring 430. The motor 410 is mounted on the partition 110 and is connected to the gear 420 for transmission. The gear ring 430 is fitted around the outer circumference of the rotating ring 210 and is meshed with the gear 420, so that the motor 410 drives the rotating screen 200 to rotate and filter through the meshing of the gear 420 and the gear ring 430. The drive device 400 is installed in the mounting chamber of the housing 100. A cover can be fitted over the motor 410 to prevent sewage from spilling onto the motor 410.
[0047] Furthermore, the microfilter also includes a backwashing assembly, which includes a water pump 510 and a water pipe 520. The water pump 510 is mounted on the partition 110, and the outlet of the water pump 510 is connected to the water pipe 520. The outlet 521 of the water pipe 520 is located below the rotary filter screen 200, and the outlet 521 of the water pipe 520 is opposite to the scraper 300, so that the water pump 510 backwashes the rotary filter screen 200 through the outlet 521 of the water pipe 520. This achieves backwashing of impurities scraped on the rotary filter screen 200, which flow along the scraper 300 into the drain port 130 and are discharged to the outside, thereby cleaning the filter screen 220 of the rotary filter screen 200 and preventing impurities from clogging the filter holes of the rotary filter screen 200 and affecting the filtration effect, thus further improving the filtration efficiency and filtration effect.
[0048] Preferably, the water pipe 520 has multiple outlets 521, which are spaced apart along the length of the scraper 300. The inlet of the water pump 510 extends into the clean water chamber of the housing 100 through the pipe 530. With this arrangement, the impurities accumulated near the scraper 300 on the rotary filter screen 200 are evenly washed through the multiple outlets 521, resulting in a better cleaning effect on the filter screen 220. Furthermore, the water used to wash the filter screen 220 is the filtered water in the clean water chamber. After washing the filter screen 220, the water is filtered again and circulated back into the clean water chamber, resulting in a better washing effect. There is no need to set up an external water tank for washing the filter screen 220. The structure is simple and convenient to use.
[0049] The partition 110 has multiple perforations so that the multiple outlets 521 of the water pipe 520 can be inserted into the multiple perforations from the bottom for installation. The multiple outlets 521 are all located below the filter screen 220 so as to achieve reverse flushing of the filter screen 220 from bottom to top, resulting in a better flushing effect.
[0050] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0051] This invention relates to a disc-type microfiltration machine that filters fishpond wastewater using a rotating disc filter screen 200. A scraper 300 is installed above the rotating disc filter screen 200. When the drive device 400 drives the rotating disc filter screen 200 to rotate, the scraper 300 scrapes away the impurities filtered out on the rotating disc filter screen 200, thereby preventing impurities from accumulating and clogging the filter holes of the rotating disc filter screen 200 and affecting the filtration effect. Furthermore, a circulating rotation filtration method is adopted, allowing the rotating disc filter screen 200 to rotate and perform dynamic continuous filtration. This ensures that the area on the rotating disc filter screen 200 cleaned by the scraper 300 rotates again to receive fishpond wastewater for continuous filtration. In this way, a portion of the area on the rotating disc filter screen 200 is cleaned of the impurities filtered out in the previous filtration each time it receives fishpond wastewater, thus ensuring filtration effect and efficiency, facilitating use, and improving the applicability and convenience of the product.
