Description

Technical Field

[0001] The invention relates to the technical field of water filtration and purification, and in particular to a heavy metal wastewater treatment and filtration device. Background Art

[0002] Heavy metal wastewater refers to the general term for water discharged and residual water during the production and manufacturing activities. It includes industrial sewage, industrial wastewater, and other unused water such as residual water in the production process that flows into drainage pipes. It generally refers to water that cannot be recycled after certain technical treatment or water that cannot meet certain standards for purification after primary pollution.

[0003] It has been found in the use of existing metal wastewater purification devices that when metal wastewater is purified, the residue in the metal wastewater is prone to clogging when filtering, resulting in poor sewage treatment effect of the equipment. In addition, traditional water quality filtration and purification devices have fewer filtration steps, and the water quality purification effect is not ideal. At the same time, the impurities filtered out during the water filtration process are not easy to clean.

[0004] In view of this, research and improvement are carried out on the existing problems, and a heavy metal wastewater treatment and filtration device is provided. The device ensures effective filtration of sewage by installing a multi-stage filtration structure and has a reasonable structural design. The purpose is to solve the problem and improve the practical value through this technology. Summary of the invention

A belt 15 is wound around and connected between the first filter tank 9 and the second pulley 13, a scraper 16 is fixedly connected to the surface of the belt 15, a filter screen 17 is fixedly connected to the inner wall of the first filter tank 9, a second sewage pipe 18 is fixedly connected to one side of the first filter tank 9, and one side of the second sewage pipe 18 is fixedly connected to the second filter tank 20, a filter pipe 21 is arranged inside the second filter tank 20, one end of the second sewage pipe 18 is connected to the filter pipe 21, one end of the filter pipe 21 is fixedly connected to a pipe cover 23, and the pipe cover 23 is located on the outside of the second filter tank 20, a connecting pipe 24 is fixedly connected to the bottom of the second filter tank 20, a third filter tank 25 is fixedly connected to the bottom of the connecting pipe 24, and a connecting pipe 26 is fixedly connected to the bottom of the third filter tank 25.

[0030] Specifically, a bearing ring 4 is fixedly embedded in the top of the purification tank 2, the interior of the bearing ring 4 is fixedly connected to the stirring shaft 5, the stirring shaft 5 is located inside the purification tank 2, and a stirring rod 6 is fixedly connected to the surface of the stirring shaft 5. This structure can effectively mix the dirt and dissolved substances in the water through the movement of the stirring rod 6, thereby improving the purification efficiency.

[0031] Specifically, the scraper 16 is made of rubber material and is evenly arranged on the belt 15 . The scraper 16 of this structure is evenly arranged on the belt 15 , and can evenly remove impurities and residues from the filter screen 17 of the belt 15 , and keep the filter screen 17 clean.

[0032] Specifically, a valve is fixedly installed on the outer side of the first sewage pipe 8, and a water pump 19 is fixedly connected to the outer surface of the second sewage pipe 18. This structure facilitates the transportation of sewage and makes operation and maintenance more convenient.

[0033] Specifically, the shape and structure of the filter pipe 21 is spiral, and filter holes 22 are evenly distributed on the surface of the filter pipe 21. The spiral pipe structure can effectively increase the length of the filter pipe 21, thereby increasing the filtering surface area.

The threaded connection can effectively prevent leakage and is relatively easy to operate during disassembly, and is suitable for equipment components that require periodic replacement or maintenance.

[0036] Working principle: When using the device, first, sewage flows into the purification tank 2 from the water inlet pipe 7, and then the first motor 3 is started. The first motor 3 drives the stirring shaft 5 to rotate, and the stirring shaft 5 drives the stirring rod 6 to rotate, so as to fully stir the sewage and make the sewage purification process more uniform. Then the valve is manually opened to allow the filtered sewage to enter the first filter tank 9. At the same time, the second motor 10 is connected to an external power supply, and the second motor 10 is started by pressing the motor button. The second motor 10 drives the active roller 11 to rotate at the same time, and the active roller 11 drives the first pulley 13 to rotate. The first pulley 13 then drives the belt 15 to rotate, and the belt 15 drives the driven roller 12 to rotate at the same time, so that the scraper 16 on the belt 15 scrapes the solid waste on the filter screen 17, and the scraper The removed waste enters the interior of the second waste filter tank 20 through the second sewage pipe 18, thereby realizing the re-filtration of the wastewater. Then, when the sewage flows in the spiral filter pipe 21, centrifugal force will be generated. At this time, the sewage will flow into the interior of the third filter tank 25 from the filter holes 22 on the surface of the filter pipe 21, and then pass through the connecting pipe 26 on the bottom surface of the third filter tank 25. At the same time, smaller impurities in the sewage are retained in the filter pipe 21. The pipe cover 23 at the end of the filter pipe 21 can be opened to flush the filter pipe 21. The sewage after the second filtration flows into the third filter tank 25, and flows into the activated carbon filter device 27 through the connecting pipe 26 at the bottom of the third filter tank 25. The sewage after the third filtration is finally discharged from the third sewage pipe 28.
