Description

Technical Field

[0001] The invention relates to the technical field of microfilters, and in particular to a microfilter for sewage treatment. Background Art

[0002] A microfilter is a mesh filter that intercepts fine suspended matter. Sewage refers to the discharged water from life and production that has been polluted to a certain extent and has lost its original function. It is mainly water used in life. It contains more organic matter and is easier to handle. Contaminated water cannot be used again, so it needs to be filtered. In real life, sewage is treated through a microfilter.

[0003] For example, the Chinese patent with the announcement number CN114180743A discloses a sewage treatment microfiltration machine, including a workbench, a fixing device and a filtering device, the upper end surface of the workbench is provided with a fixing device and a filtering device, and the filtering device includes an annular hollow cylinder, a filter barrel, a filter screen, a rotating frame, a water inlet frame, a vertical plate, a protruding plate, a rotating rod, a limiting circular plate, a rope and a cleaning frame.

[0004] However, the above scheme has the following shortcomings: in the above patent, the material box slides on the limiting long block, so that the material box drives the telescopic spring rod to be located in the filter barrel, so that the scraper and the filter screen are in contact, and when the rope is reeled in, the rope pulls the material box to slide to the right on the limiting long block, so that the scraper scrapes off the suspended particles on the inner wall of the filter screen, but when the scraper scrapes off the filtered material on the surface of the filter screen, part of the filtered material will be squeezed into the filter holes of the filter screen, so that the filter screen is blocked, resulting in the filter screen being unable to completely filter the sewage. For this reason, we have launched a microfiltration machine for sewage treatment. Summary of the invention

One end of the connecting spring 24 is fixedly connected to the connecting cavity 25, and the other end is fixedly connected to the T-shaped rod 26. The lower end of the connecting cavity 25 is connected to the hydraulic transmission mechanism. Under the push of the hydraulic oil, the T-shaped rod 26 moves upward along the connecting cavity 25. At this time, the connecting spring 24 is compressed, and the two T-shaped rods 26 move upward synchronously to drive the cleaning brush 10 to move. The cleaning brush 10 moves upward and finally contacts the inner wall of the connecting pipe 2; The drainage and filtering mechanism includes a plurality of through holes 11, a plurality of second drainage holes 17 are provided on the outside of the connecting pipe 2, and the through groove 21 is connected with the second drainage holes 17 and the through hole 11.

At the same time, the through hole 11 filters the sewage, and the filtered water source is discharged from the connecting box 1 through the drainage pipe 18. The upper and lower sides of the push rod 15 are fixedly connected with the connecting rod 13, and the connecting rod 13 is slidably connected to the guide groove 19. The guide groove 19 is provided on the outside of the connecting column 3. The end of the connecting rod 13 away from the push rod 15 is fixedly connected to the inner side of the connecting ring 12, and a T-shaped groove 20 is provided in one end of the connecting ring 12. One end of the T-shaped baffle 8 is slidably connected to the T-shaped groove 20. During the rotation of the connecting pipe 2, the T-shaped baffle 8 will move along the T-shaped groove 20. The transmission mechanism includes a connecting motor 28, and a connecting motor 28 is fixedly connected to one side of the connecting box 1. The output end of the connecting motor 28 is fixedly connected to a transmission pulley 29. Two pulleys 5 are connected to the transmission pulley 29 through a belt 27. When the connecting motor 28 is turned on, the transmission pulley 29 connected to the output end starts to rotate. During the rotation process, the transmission pulley 29 drives the two pulleys 5 to rotate through the belt 27. The rotation of the pulley 5 drives the connecting pipe 2 to rotate.

[0027] Working principle: when in use, connect the extended end of the connecting column 3 to the external sewage pipe connected to the three-way solenoid valve, so that the domestic sewage can enter the guide cavity 4, and the sewage entering the guide cavity 4 is discharged into the inner side of the connecting pipe 2 through a plurality of first drainage holes 16, and the connecting motor 28 is turned on to drive the transmission pulley 29 connected to the output end to start rotating, and the transmission pulley 29 drives the two pulleys 5 to rotate through the belt 27 during the rotation process, and the rotation of the pulley 5 drives the connecting pipe 2 to rotate, and the sewage entering the connecting pipe 2 is discharged from the plurality of through holes 11 into the connecting box 1 under the rotation of the connecting pipe 2, and the through holes 11 filter the sewage at the same time, and the filtered water source is discharged from the connecting box 1 through the drainage pipe 18; When it is necessary to clean the filtered matter adhering to the inner side of the connecting tube 2 and the surface of the through hole 11, the telescopic cylinder 14 is opened to drive the push rod 15 connected to its output end to start moving, and the push rod 15 moves to drive the T-shaped push plate 7 to move along the liquid storage chamber 22. At this time, the hydraulic oil in the liquid storage chamber 22 will be pushed into the liquid guide chamber 23, and the hydraulic oil entering the liquid guide chamber 23 will then enter the two connecting chambers 25. Under the push of the hydraulic oil, the T-shaped rod 26 moves upward along the connecting chamber 25. At this time, the connecting spring 24 is compressed, and the two T-shaped rods 26 move upward synchronously to drive the cleaning brush 10 to move. The cleaning brush 10 moves upward and finally contacts the inner wall of the connecting tube 2. At the same time, when the push rod 15 moves, the two connecting rods 13 will also be driven to move, and when the connecting rod 13 moves, the connecting ring 12 will be driven to move. Since one end of the connecting ring 12 is movably connected to a plurality of T-shaped baffles 8, during the movement of the connecting ring 12, the plurality of T-shaped baffles 8 will follow and move along the through groove 21. At this time, the connecting hole 9 will enter the through groove 21, and the T-shaped baffle 8 will block the through hole 11. At the same time, as the T-shaped baffle 8 moves, the connecting hole 9 will enter the second drainage hole 17, and the T-shaped baffle 8 will cancel the blocking of the second drainage hole 17. The three-way solenoid valve is started to transport the clean water source to the guide cavity 4, and finally discharged into the connecting pipe 2 through the first drainage hole 16; During the rotation of the connecting pipe 2, the cleaning brush 10 will clean the inner wall of the connecting pipe 2 and the through hole 11 at the same time. The clean water source entering the guide cavity 4 is discharged through a plurality of first drainage holes 16 to flush the inner wall of the connecting pipe 2 and the through hole 11. The filtered matter flushed out is carried by the water source and discharged into the connecting box 1 from a plurality of second drainage holes 17, and finally discharged into the external environment through the drainage pipe 18. When the cleaning is completed, the telescopic cylinder 14 is controlled to drive the push rod 15 to move downward. At this time, the hydraulic oil re-enters the liquid storage cavity 22. Under the elastic force of the connecting spring 24, the T-bar 26 returns to its initial position. At this time, the cleaning brush 10 is retracted and no longer contacts the inner wall of the connecting pipe 2.

[0028] The above embodiments are only used to help understand the method and core idea of ​​the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
