Description

Technical Field

[0001] This utility model relates to the field of wastewater screening technology, and in particular to a wastewater screening structure for high-turbidity liquids. Background Technology

[0002] High-turbidity liquids refer to liquid systems that exhibit a highly turbid state due to the presence of large amounts of suspended solid particles, colloidal substances, microbial aggregates, and various other impurities. These liquids are extremely common in our daily lives, widely present in industrial production, municipal drainage, and agricultural non-point source pollution. During mining, the crushing and washing of ore generates large amounts of wastewater, which carries a significant amount of rock powder, resulting in very high turbidity. In steel smelting, slag flushing water contains high concentrations of iron oxide scale particles, causing turbidity. Furthermore, the turbidity of mud slurry water is extremely high in river dredging, construction mud disposal, and other activities. These all fall under the category of high-turbidity liquids. In addition, high-turbidity liquids can also occur in food processing, papermaking, textile printing and dyeing, and other industries. The wastewater generated during these processes also contains large amounts of suspended solids and impurities, making the liquid turbid. Currently, traditional technologies for screening and treating high-turbidity liquids mainly employ equipment such as bar screens, filters, and sedimentation tanks.

[0003] Traditional methods for treating highly turbid liquids primarily rely on facilities and processes such as bar screens, filters, and grit chambers. Bar screens typically consist of a series of parallel metal bars or mesh screens, installed at an angle at the inlet of sewage channels or pump house sump wells. In actual high-turbidity liquid treatment, even after bar screen pretreatment, some larger impurities, such as broken plastic fragments and clumps of fibers, still remain. These impurities, impacted by the water flow, reach the filter screen and become trapped in the pores, entangled with tiny suspended solids and viscous colloids. Once impurities begin to accumulate, a chain reaction quickly occurs, filling the surrounding pores with entrained fine particles. This leads to a rapid expansion of the clogging area on the filter screen surface. Currently, the removal of these clogging impurities mainly relies on manual processing. After the equipment is shut down, operators must wear protective gear and use hooks and shovels to manually remove plastic fragments and fiber clumps stuck in the filter screen pores. Since high-turbidity liquid treatment equipment is usually large in size and has a large filter screen area, manual cleaning requires a lot of time and physical effort. In addition, the sewage may contain corrosive substances and harmful microorganisms, posing health risks to operators. Frequent manual cleaning not only increases labor costs but also extends equipment downtime, seriously affecting the continuity and efficiency of sewage treatment. Utility Model Content

[0036] Specifically, on the right side of the filter plate 208, a rubber ring 18 is fixedly connected to it. The function of this rubber ring 18 is to prevent sewage leakage. At the same time, a handle 2 19 is fixedly connected to the middle of the right side of the filter plate 208. This handle 2 19 is for the operator to adjust the filter plate 208.

[0037] Please see the appendix Figure 1 and attached Figure 2At the front end of the outer casing 1, there is a sewage inlet 14, which is installed on the front side of the outer casing 1 to facilitate the flow of sewage. At the rear end of the outer casing 1, there is a sewage outlet 15, which is fixed to the rear side of the outer casing 1 for discharging treated sewage. The top of the outer casing 1 is equipped with a top plate 16, which is tightly connected to the outer casing 1 to provide further support for the structure. Above the sewage outlet 15, a collection trough 13 is also installed, which is responsible for collecting the impurities separated from the hook 10 for subsequent processing and recycling.

[0038] Specifically, the front part of the outer casing 1 has a sewage inlet 14, which is fixedly connected to the front of the outer casing 1 to facilitate the entry of sewage. At the same time, the rear part of the outer casing 1 has a sewage outlet 15, which is fixedly connected to the rear of the outer casing 1 for discharging treated sewage. In addition, the top of the outer casing 1 has a top plate 16, which is fixedly connected to the top of the outer casing 1 to provide additional structural support. A collection trough 13 is also fixedly connected to the top of the sewage outlet 15. The collection trough 13 is used to collect impurities screened from the hook 10 for subsequent treatment and recycling.

[0039] Working principle: By starting motor 4, the output end of motor 4 drives short shaft 5 to rotate, which causes bevel gear 6 to rotate with short shaft 5, which in turn causes bevel gear 7 to rotate with bevel gear 6. The rotation of bevel gear 7 drives pulley 8 to rotate, which in turn drives belt 11 to rotate. Belt 11 then drives the fixed plate 9 and hook 10 on the outer wall to rotate, thus achieving the screening out of larger impurities in the wastewater.

[0040] By manually turning the handle 203, the handle 203 drives the rotating shaft 204 to rotate, causing the rotating disk 205 to rotate along with the rotating shaft 204. By turning the slot 206 downward, the rotating disk 205 can be locked in the slot 207. Similarly, turning the slot 206 upward allows the filter plate 208 to pass through the slot 206, thereby achieving quick replacement and cleaning of the filter screen 22.
