Description

Wastewater filtration device

Technical Field

The present application relates to wastewater treatment technology, and in particular to a wastewater filtering device.

Background Art

In the wastewater treatment process of chemical production, filtering equipment is usually used to filter suspended matter, particles and other solid impurities in the wastewater. At present, the commonly used wastewater filtering equipment includes a box body, which is connected to an inlet pipe and a drain pipe. A horizontally distributed filter plate is arranged in the box body, and the filter plate is located between the inlet pipe and the drain pipe. When in use, the wastewater to be filtered enters the box body from the inlet pipe and falls onto the filter plate. The filter plate intercepts the solid impurities in the wastewater. The wastewater passes through the filter plate and falls to the bottom of the box body and is discharged from the drain pipe, thereby completing the filtration of the wastewater. Among them, after the filter plate filters the wastewater for a long time, solid impurities will accumulate on the filter plate. In order to ensure the filtration efficiency, the solid impurities on the filter plate need to be cleaned regularly.

However, when cleaning the filter plate, the delivery of wastewater to the water inlet pipe must be stopped first, and the box cover on the top of the box must be opened first. Then the staff uses a hand-held scraper to scrape up the solid impurities on the filter plate and collect them together. Then the staff uses auxiliary tools such as a shovel to shovel the solid impurities concentrated on the filter plate out of the box, and finally closes the box cover to continue filtering. This not only makes the entire filter plate cleaning process complicated, time-consuming, and inefficient, but also causes a long downtime of the filtration equipment.

After the scraper device 3 rotates, the scraper device 3 can scrape all solid impurities on the filter plate 2 to the position of the discharge notch 203, thereby improving the cleaning effect of the filter plate 2.

In this embodiment, a bracket 103 is fixed to the bottom of the box 1 for supporting the box 1 .

When filtering wastewater, first rotate the scraper device 3 to the position of the discharge gap 203, close the discharge gap 203, and then the wastewater enters the box 1 from the water inlet pipe 101, and then falls on the filter plate 2. The filter plate 2 intercepts solid impurities such as suspended matter and particles in the wastewater. The wastewater passes through the filter plate 2 and falls to the bottom of the box 1, and is discharged from the drain pipe 102 to enter the next treatment process, thereby achieving the filtering of the wastewater.

When cleaning the filter plate 2, the staff operates the scraper device 3 to rotate the scraper device 3, and the scraper device 3 scrapes up the solid impurities on the filter plate 2 and pushes the solid impurities on the filter plate 2 to the position of the discharge notch 203. After the scraper device 3 rotates continuously, all the solid impurities on the filter plate 2 can be scraped to the position of the discharge notch 203. After the solid impurities reach the position of the discharge notch 203, they fall freely into the collection frame 4, thereby completing the cleaning of the filter plate 2. After the filter plate 2 is cleaned, the scraper device 3 is rotated again, and after the scraper device 3 closes the discharge notch 203, the filtering work can be continued. Among them, the solid impurities in the collection frame 4 can be cleaned regularly. Since the scraper device 3 closes the discharge notch 203, and the collection frame 4 is connected to the discharge notch 203, there is no need to stop the machine when cleaning the collection frame 4.

The wastewater filtering device provided in the present embodiment is provided with a circular box body 1, the box body 1 is connected with a water inlet pipe 101 and a drain pipe 102, a circular filter plate 2 is fixed inside the box body 1, and the filter plate 2 is provided with discharge notches 203 distributed along its radial direction, and the upper end of the filter plate 2 is provided with a scraper device 3 that can rotate around the center, and the scraper device 3 can close the discharge notch 203, and the lower end of the discharge notch 203 is provided with a collecting frame 4 that can move out of the box body 1, so that when cleaning the filter plate 2, only the scraper device 3 needs to be rotated to clean the solid impurities on the filter plate 2, which is not only convenient to operate, but also can shorten the cleaning time of the filter plate 2, improve the cleaning efficiency of the filter plate 2, and thus can shorten the downtime.
