Description

Technical Field

[0001] This utility model belongs to the field of water filtration technology, specifically relating to a water pollution treatment mechanism. Background Technology

[0002] The background technology of rotary drum filters stems from the demand for efficient and continuous operation equipment in the field of solid-liquid separation. Traditional filtration technology suffers from problems such as low efficiency, high energy consumption, and frequent filter replacement. It is particularly prone to clogging when treating wastewater with high suspended solids, resulting in high maintenance costs. In the late 20th century, after Germany introduced stainless steel membrane filtration technology, rotary drum filters achieved a revolution in solid-liquid separation by combining centrifugal force with porous media: wastewater forms centrifugal shear force as the drum rotates, and suspended solids are trapped inside the filter screen. At the same time, impurities are removed by backwashing through a high-pressure nozzle at the top, forming a continuous filtration cycle.

[0003] Chinese patent, publication number CN219251887U, discloses a rotary drum filter. When purifying sewage through the filter, sewage is first introduced into the tank through the inlet pipe, and then filtered through the filter drum inside the tank. During the filtration process, the control mechanism controls the filter drum to rotate intermittently, which can effectively clean impurities in the sewage. The intermittent rotation can also extend the service life of the filter drum.

[0004] However, existing rotary filters often become clogged after a period of use, requiring a large amount of water to backwash the filter. The backwashed water is discharged from the drain outlet along with the foreign objects. The backwashing frequency is relatively high, and the amount of water used for each backwash is large, resulting in a certain waste of water resources. Utility Model Content

A water inlet is provided on the other side of the housing and communicates with the water inlet chamber.

[0010] Preferably, a liquid level sensor is installed in the water inlet chamber, and the liquid level sensor is electrically connected to the water pump.

[0024] As a preferred option, a water inlet tank 12 is fixedly installed between the two upright plates 11. Ten flushing nozzles 13 are installed at equal intervals at the bottom of the water inlet tank 12. The flushing nozzles 13 are located above the filter drum 4. The flushing nozzles 13 are adapted to the sewage discharge tank 6 and are arranged facing the sewage discharge tank 6. The water flushed by the flushing nozzles 13 enters the sewage discharge tank 6.

During use, rust-preventive oil or grease should be applied to form a protective film to isolate water and oxygen. The sprockets and chains should be coated with zinc-plated, nickel-plated, or epoxy zinc-rich rust-preventive paint.

A reinforcing rib 88 is connected between the connecting plate 86 and the swing rod 84. The reinforcing rib 88 is used to improve the connection strength between the connecting plate 86 and the swing rod 84.

[0031] As a preferred option, furthermore, support columns 22 are installed at the four corners of the bottom of the enclosure 1, and a control box 23 is fixedly installed on one side of the enclosure 1 by bolts. The control box 23 is used to control the switching of electrical components and monitor the status of the equipment.

[0032] The motor, filter drum, flushing nozzle, water pump, and control box in this case are existing technologies, and any motor, filter drum, flushing nozzle, water pump, and control box that meet the requirements of this case are acceptable.

[0033] The specific types or circuit structures of the controllers for the electrical components mentioned in this application, as well as the circuit connection relationships between the electrical components and the accurate coordinated control of multiple power components, are all prior art. Therefore, the above content will not be elaborated upon in this application.

[0034] Working principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions of this utility model before use. During use, the water to be treated is discharged from the inlet 19 into the inlet chamber 17. The water enters the filter drum 4 and is filtered. The filtered water is discharged through the drain pipe 21. The motor 2 is started, driving the output shaft 3 to rotate, which in turn drives the filter drum 4 to rotate. Simultaneously, the output shaft 3 rotates, driving the first sprocket 91 to rotate. The first sprocket 91, through the first chain 93, drives the second sprocket 92 to rotate. The second sprocket 92 drives the first rotating shaft 5 to rotate, causing the first rotating shaft 5 to drive the third sprocket 101 to rotate. 01 The second chain 103 drives the fourth sprocket 102 to rotate, the fourth sprocket 102 drives the second rotating shaft 7 to rotate, the rotating shaft 7 drives the sleeve rod 82 to rotate, and the sleeve rod 82 drives the swing rod 84 to swing around the connecting shaft 83 through the connecting rod 85. The swing rod 84 swings through the connecting plate 96 and the brush 87, so that the brush 87 scrapes and cleans the surface of the filter cylinder 4. The scraped foreign objects fall into the drain tank 6, thereby achieving the effect of continuously cleaning the surface of the filter cylinder 4 and reducing the number of times the filter cylinder 4 is rinsed by the flushing nozzle 13. Only the water pump 14 needs to be started periodically to pump the water in the filter chamber 18 into the water inlet tank 12, and the filter cylinder 4 is backwashed once by the flushing nozzle 13. At the same time, the foreign objects accumulated in the drain tank 6 are discharged from the drain pipe 20.

[0035] When the cleaning effect of the brush 87 deteriorates after a certain period of use, the filter screen on the filter drum 4 becomes clogged, triggering the liquid level sensor in the water inlet chamber 17. The liquid level sensor detects the water level change and converts it into an electrical signal, controlling the water pump 14 to start, so that the water pump 14 draws water into the water inlet tank 12, and backwashes the filter screen of the filter drum 4 through the flushing nozzle 13, flushing the clogged foreign objects into the drain tank 6.
