Description

A vertical disc filter capable of fine processing

Technical Field

The invention relates to the field of filtering equipment, in particular to a vertical disc filter capable of fine processing.

Background Art

Nowadays, with the continuous progress and development of modern industry, filters are needed to handle some sludge, wastewater and other substances that need to be filtered and discharged. Currently, most of the filters used are vertical disc filters, which make the wastewater pass through the rotating filter in turn. During the filtration process, solid matter will adhere to the surface of the filter.

However, for most disc filters, during long-term use, more and more solid particles adhere to the surface of the filter, causing the mesh of the filter to become more and more clogged. The filter cannot filter impurities normally. In order to remove impurities on the surface of the filter, most disc filters have multiple sets of scraping grooves on the side to scrape off the dirt on the surface of the filter during the rotation of the filter. However, the cleanliness of the filter surface cannot be ensured, and the fine processing cannot be performed. Finally, the filtered water quality is still not clear enough.

Therefore, most disc filters cannot refine the water quality. After a long period of filtration, the filtering effect of the filter will be reduced, resulting in the filtered water quality not meeting the requirements.

Summary of the invention

In order to overcome the problem that most disc filters cannot refine the water quality, the filtering effect of the filter will be reduced after a long period of filtration, resulting in the filtered water quality not meeting the requirements.

There is a water outlet pipe 8, and a top cover 6 is installed on the upper end of the fine filter barrel 5 through a hinge. A first support platform 10 is fixedly installed on the upper surface of the frame 1, and a second support platform 11 corresponding to the first support platform 10 is provided on the other side of the frame 1. A fixing frame 13 is detachably installed on the outer side of the first support platform 10, and a driving motor 12 is fixedly installed on the outside of the second support platform 11. A coupling 15 is provided at the output end of the driving motor 12, and a rotating shaft is fixedly installed at the end of the coupling 15. The disc filter body 4 is fixedly installed on the rotating shaft. The rotation of the driving motor 12 drives the coupling 15 to rotate, thereby driving the rotating shaft to rotate, so that the disc filter body 4 can rotate.

Please refer to Figures 1 to 4. Support plates 501 are fixedly connected to both sides of the refinement filter barrel 5. A connecting plate 601 is fixedly connected to the outer side of the top cover 6. The connecting plate 601 is installed on the supporting plate 501 by hexagonal bolts. The top cover 6 can be fixed to the refinement filter barrel 5 by the cooperation between the connecting plate 601 and the supporting plate 501. A guide bucket 503 is provided at the end of the refinement filter barrel 5. A through hole corresponding to the guide bucket 503 is opened on the outer surface of the filter pool 2. A support rod 14 is fixedly installed at the lower end of the support plate 501. The filtered water in the filter pool 2 can flow into the refinement filter barrel 5 from the guide bucket 503. Evenly distributed blocks 502 are fixedly installed at the bottom of the refinement filter barrel 5. The refinement filter screen 9 is arranged between two adjacent refinement filter screens 9. By setting the blocks 502, the refinement filter screen 9 can be fixed to prevent the refinement filter screen 9 from deflecting.

Please refer to Figures 5 and 6. The disc filter body 4 includes a mounting frame 401, which is evenly distributed on the outer surface of the rotating shaft. A first filter screen 402 is installed on one side of the mounting frame 401 by bolts, and a second filter screen 403 is arranged on the other side of the mounting frame 401. The first filter screen 402 and the second filter screen 403 are symmetrically distributed. The mounting frame 401 fixes the first filter screen 402 and the second filter screen 403 to facilitate subsequent disassembly and maintenance. A first protrusion 404 is arranged on the surface of the first filter screen 402 and the second filter screen 403, and a second protrusion 405 is arranged on the outer side of the first protrusion 404. The first protrusion 404 and the second protrusion 405 are engaged in the mounting frame 401, so as to realize the positioning and installation of the first filter screen 402 and the second filter screen 403.

Please refer to Figures 1 to 3. One side of the filter tank 2 is provided with evenly distributed scraping grooves 201, and the upper surface of the filter tank 2 is fixedly installed with evenly distributed scrapers 16. The scrapers 16 and the scraping grooves 201 are staggered with each other. The scrapers 16 can scrape the surfaces of the first filter screen 402 and the second filter screen 403 near the rotating shaft, and the scraping grooves 201 can scrape off impurities on the end faces and annular surfaces of the first filter screen 402 and the second filter screen 403, so that the filter screens can filter the water normally.

When working, the water inlet pipe 7 is connected to the external drainage pipe, and the water outlet pipe 8 outside the fine filter barrel 5 is connected to the external water pipe, so that the external water can flow into the filter tank 2 through the water inlet pipe 7, and then the drive motor 12 is turned on. The drive motor 12 rotates to drive the coupling 15 to rotate, thereby driving the rotating shaft to rotate, so that the disc filter body 4 can rotate. When the first filter screen 402 and the second filter screen 403 rotate, the impurities on the first filter screen 402 and the second filter screen 403 will be scraped off from the scraping groove 201 outside the filter tank 2, fall into the impurity collection box 3, and then fall out from the discharge port on the lower side of the impurity collection box 3. After being gradually filtered by the first filter screen 402 and the second filter screen 403, the water in the filter tank 2 will flow into the fine filter barrel 5 from the guide bucket 503, and then flow out from the water outlet pipe 8 after being filtered by the fine filter screen 9.

Through the above steps, by setting up the impurity collection box 3, during the rotation of the disc filter body 4, the impurities on the surface of the disc filter body 4 will be scraped off by the edge of the filter pool 2 and the scraper 16, and the impurities will fall into the impurity collection box 3, which can avoid excessive impurities on the surface of the disc filter body 4 and affect the normal filtering operation. The fine filter barrel 5 can be used to collect the water discharged from the filter pool 2, and then filter it in turn through the fine filter net 9 before discharging it, thereby improving the filtering effect and ensuring that the filtered water quality can meet the standard, so as to solve the problem that most vertical disc filters cannot refine the water quality, and the filtering effect of the filter net will be reduced after a long period of filtration, resulting in the filtered water quality not meeting the requirements.

The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
