Description

Technical Field

[0001] This invention relates to the field of microfiltration technology, and in particular to a microfiltration machine for wastewater treatment. Background Technology

[0002] A microfiltration machine is a screen filter that traps fine suspended solids. Wastewater refers to water discharged from domestic and industrial sources that has been polluted and lost its original function. It is mainly water used in daily life, which contains a lot of organic matter and is relatively easy to treat. Polluted water cannot be reused, so it needs to be filtered. In real life, microfiltration machines are used to treat wastewater.

[0003] For example, Chinese patent CN114180743A discloses a wastewater treatment microfiltration machine, which includes a workbench, a fixing device and a filtration device. The upper surface of the workbench is provided with the fixing device and the filtration device. The filtration device includes an annular hollow cylinder, a filter barrel, a filter screen, a rotating frame, a water inlet frame, a vertical plate, an extension plate, a rotating rod, a limiting circular plate, a rope and a cleaning frame.

[0004] However, the above solution has the following shortcomings: In the above patent, the material container slides on the limiting block, so that the material container drives the telescopic spring rod to be located inside the filter barrel, so that the scraper and the filter screen come into contact. When the rope is wound up, the rope pulls the material container to slide to the right on the limiting block, so that the scraper scrapes off the suspended particles on the inner wall of the filter screen. However, when the scraper scrapes off the filter material on the surface of the filter screen, some of the filter material will be squeezed into the filter holes of the filter screen, causing the filter screen to be blocked, resulting in the filter screen not being able to completely filter the sewage. Therefore, we have introduced a microfiltration machine for sewage treatment. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a microfiltration machine for wastewater treatment to solve the problems mentioned in the background art.

[0006] The objective of this invention is achieved as follows: A microfiltration machine for wastewater treatment includes a connecting box with a cover snapped onto its upper end. Two connecting columns are fixedly connected to the inner side of the connecting box. One end of each connecting column has a guide cavity extending into the external environment. The lower end of each connecting column has several first drainage holes that communicate with the guide cavity. A connecting pipe is movably sleeved on the outer side of the connecting column. A cleaning mechanism is movably connected to the connecting column and is connected to a hydraulic transmission mechanism. The hydraulic transmission mechanism is located inside the connecting column and is connected to a pushing mechanism, which is also located inside the connecting column. The hydraulic transmission mechanism pushes the cleaning mechanism upward, causing it to contact the inner side of the connecting pipe. Several drainage filtration mechanisms are located on the outer side of the connecting pipe, and several through slots are opened inside the outer side of the connecting pipe. These through slots are connected to the drainage filtration mechanisms, which filter and discharge wastewater.

[0007] A T-shaped baffle is slidably connected within the through groove. Several connecting holes are provided at the upper end of the T-shaped baffle. One end of the T-shaped baffle extends into the external environment and is movably connected to a pushing mechanism. The pushing mechanism pushes the T-shaped baffle to move along the slid groove. A pulley is fixedly sleeved on the outside of the connecting pipe. Both pulleys are connected to a transmission mechanism. The transmission mechanism drives the pulleys to rotate, and the rotation of the pulleys drives the connecting pipe to rotate. A drain pipe is fixedly connected to one end of the connecting box.

[0008] Furthermore, the cleaning mechanism includes a cleaning brush, the lower end of which is fixedly connected to two T-shaped rods. The T-shaped rods slide within a connecting cavity, which is located within a connecting column. A connecting spring is sleeved on the outer side of each T-shaped rod. One end of the connecting spring is fixedly connected to the connecting cavity, and the other end is fixedly connected to the T-shaped rod. The lower end of the connecting cavity is connected to a hydraulic transmission mechanism.

[0009] Furthermore, the hydraulic transmission mechanism includes a reservoir cavity, which is located within a connecting column. A T-shaped push plate is slidably connected within the reservoir cavity. One end of the T-shaped push plate is connected to a pushing mechanism. Hydraulic oil is provided within the reservoir cavity. The reservoir cavity is connected to a guide cavity, which is located within the connecting column. The lower end of the connecting cavity is connected to the guide cavity.

[0010] Furthermore, the pushing mechanism includes a pushing rod that slides within a sliding cavity, which is located at one end of a connecting column. One end of the pushing rod is fixedly connected to a T-shaped push plate, and the other end passes through the connecting box and is fixedly connected to the output end of a telescopic cylinder. The telescopic cylinder is fixedly connected to the outside of the connecting box.

[0011] Furthermore, the drainage filtration mechanism includes several through holes, and several second drainage holes are provided on the outside of the connecting pipe. The through groove is connected to the second drainage holes and the through holes.

[0012] Furthermore, the upper and lower sides of the push rod are fixedly connected to connecting rods, the connecting rods are slidably connected in the guide groove, the guide groove is opened on the outside of the connecting column, the end of the connecting rod away from the push rod is fixedly connected to the inside of the connecting ring, one end of the connecting ring is provided with a T-shaped sliding groove, and one end of the T-shaped baffle is slidably connected in the T-shaped sliding groove.

[0013] Furthermore, the transmission mechanism includes a connecting motor, a connecting motor is fixedly connected to one side of the connecting box, the output end of the connecting motor is fixedly connected to the transmission pulley, and the two pulleys are connected to the transmission pulley via a belt.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: by driving the hydraulic transmission mechanism to move, the cleaning mechanism rises and contacts the inner wall of the connecting pipe. The transmission mechanism drives the connecting pipe to rotate, and the T-shaped baffle blocks the drainage filtration mechanism. During the rotation of the connecting pipe, the cleaning mechanism cleans the inner wall of the connecting pipe and the through hole. The connecting column sprays water outward to rinse the dirt cleaned from the inner wall of the connecting pipe and the through hole, and finally discharges it. The cleaning brush can clean the inside of the through hole. The T-shaped baffle blocks the through hole to prevent impurities from entering the through hole, thus solving the problem of filter screen being blocked by filter material, which prevents the filter screen from filtering sewage.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-8 The present invention provides a technical solution:

[0027] Example 1:

[0028] A microfiltration machine for wastewater treatment includes a connecting box 1. A box cover 6 is snapped onto the upper end of the connecting box 1, allowing the inside of the connecting box 1 to be cleaned by opening the box cover 6. Two connecting columns 3 are fixedly connected to the inside of the connecting box 1. One end of each connecting column 3 has a guide cavity 4 that extends into the external environment and is used to guide and transport water. Several first drain holes 16 are opened at the lower end of each connecting column 3 and are connected to the guide cavity 4. A connecting pipe 2 is movably sleeved on the outside of the connecting column 3, connecting the extended end of the connecting column 3 to an external wastewater pipe connected to a three-way solenoid valve, allowing wastewater to enter the guide cavity 4. When it is necessary to clean the inner wall of the connecting pipe 2, the three-way solenoid valve will be activated, connecting the water pipe connected to the clean water source to the guide cavity 4, allowing the clean water source to enter the guide cavity 4. The wastewater entering the guide cavity 4 is discharged into the inside of the connecting pipe 2 through the several first drain holes 16.

[0029] A cleaning mechanism is movably connected to the connecting column 3. The cleaning mechanism is connected to a hydraulic transmission mechanism, which is located inside the connecting column 3. The hydraulic transmission mechanism is connected to a pushing mechanism, which is also located inside the connecting column 3. The hydraulic transmission mechanism pushes the cleaning mechanism upward, and the upward-moving cleaning mechanism contacts the inside of the connecting pipe 2. Several drainage filtration mechanisms are provided on the outside of the connecting pipe 2. Several through grooves 21 are opened on the outside of the connecting pipe 2. The through grooves 21 are connected to the drainage filtration mechanisms, and the sewage is filtered and discharged through the drainage filtration mechanisms.

[0030] A T-shaped baffle 8 is slidably connected inside the through groove 21. Several connecting holes 9 are opened in the upper end of the T-shaped baffle 8. One end of the T-shaped baffle 8 extends into the external environment and is movably connected to the pushing mechanism. The pushing mechanism pushes the T-shaped baffle 8 to move along the through groove 21. A pulley 5 is fixedly sleeved on the outside of the connecting pipe 2. Both pulleys 5 are connected to the transmission mechanism. The transmission mechanism drives the pulleys 5 to rotate. The rotation of the pulleys 5 drives the connecting pipe 2 to rotate. The sewage entering the guide cavity 4 is discharged into the inside of the connecting pipe 2 through several first drain holes 16. Under the filtration of the drainage filtration mechanism, the sewage is filtered and finally discharged into the connecting box 1. A drain pipe 18 is fixedly connected to one end of the connecting box 1. The water entering the connecting box 1 will finally be discharged into the external environment through the drain pipe 18, completing the filtration of domestic sewage.

[0031] Example 2:

[0032] Based on Embodiment 1, in order to enable the inner wall of the connecting pipe 2 and the through hole 11 to be cleaned, the hydraulic transmission mechanism includes a reservoir 22, which is located within the connecting column 3. A T-shaped push plate 7 is slidably connected within the reservoir 22, with one end of the T-shaped push plate 7 connected to the pushing mechanism. Hydraulic oil is contained within the reservoir 22. The reservoir 22 is connected to a guide cavity 23, which is located within the connecting column 3. The lower end of the connecting cavity 25 is connected to the guide cavity 23. The pushing mechanism includes a push rod 15, which is slidably connected within the sliding cavity 30. The sliding cavity 30 is opened in one end of the connecting column 3. One end of the push rod 15 is fixedly connected to the T-shaped push plate 7, and the other end passes through the connecting box 1 and is fixedly connected to the output end of the telescopic cylinder 14. The telescopic cylinder 14 is fixedly connected to the outside of the connecting box 1. When the telescopic cylinder 14 is opened, the push rod 15 connected to its output end starts to move. The movement of the push rod 15 causes the T-shaped push plate 7 to move along the liquid storage cavity 22. At this time, the hydraulic oil in the liquid storage cavity 22 will be pushed into the liquid guiding cavity 23. The hydraulic oil that enters the liquid guiding cavity 23 then enters the two connecting cavities 25.

[0033] The cleaning mechanism includes a cleaning brush 10, with two T-shaped rods 26 fixedly connected to the lower end of the cleaning brush 10. The T-shaped rods 26 slide in the connecting cavity 25, which is located inside the connecting column 3. A connecting spring 24 is sleeved on the outside of the T-shaped rods 26. 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 a hydraulic transmission mechanism. Under the push of hydraulic oil, the T-shaped rods 26 move upward along the connecting cavity 25. At this time, the connecting spring 24 is compressed. The two T-shaped rods 26 move upward synchronously, driving the cleaning brush 10 to move. The cleaning brush 10 moves upward and finally contacts the inner wall of the connecting pipe 2.

[0034] The drainage filtration mechanism includes several through holes 11. Several second drainage holes 17 are opened on the outside of the connecting pipe 2. The through groove 21 is connected to the second drainage holes 17 and the through holes 11. The sewage entering the connecting pipe 2 is discharged into the connecting box 1 through several through holes 11 under the rotation of the connecting pipe 2. At the same time, the through holes 11 filter the sewage. The filtered water is discharged into the connecting box 1 through the drain pipe 18. The upper and lower sides of the push rod 15 are fixedly connected to the connecting rod 13. The connecting rod 13 is slidably connected in the guide groove 19. The guide groove 19 is opened 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 inside of the connecting ring 12. A T-shaped sliding groove 20 is opened in one end of the connecting ring 12. One end of the T-shaped baffle 8 is slidably connected in the T-shaped sliding groove 20. During the rotation of the connecting pipe 2, the T-shaped baffle 8 will move along the T-shaped sliding groove 20.

[0035] The transmission mechanism includes a connecting motor 28. The 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 the 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 of the transmission pulley 29, the two pulleys 5 are driven to rotate through the belt 27. The rotation of the pulleys 5 drives the connecting pipe 2 to rotate.

[0036] Working principle: When in use, the protruding end of the connecting column 3 is connected to the external sewage pipe connected to the three-way solenoid valve, so that domestic sewage can enter the guide chamber 4. The sewage entering the guide chamber 4 is discharged into the inner side of the connecting pipe 2 through several first drain holes 16. The connecting motor 28 is turned on to drive the transmission pulley 29 connected to the output end to start rotating. During the rotation of the transmission pulley 29, the two pulleys 5 are driven to rotate through the belt 27. The rotation of the pulleys 5 drives the connecting pipe 2 to rotate. The sewage entering the connecting pipe 2 is discharged into the connecting box 1 through several through holes 11 under the rotation of the connecting pipe 2. At the same time, the through holes 11 filter the sewage. The filtered water is discharged from the connecting box 1 through the drain pipe 18.

[0037] When it is necessary to clean the filter material adhering to the inside of the connecting pipe 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 move. The push rod 15 moves and drives 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 is pushed into the liquid guiding chamber 23. The hydraulic oil in the liquid guiding chamber 23 then enters 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. The two T-shaped rods 26 move upward synchronously, driving the cleaning brush 10 to move. The cleaning brush 10 moves upward and finally contacts the inner wall of the connecting pipe 2.

[0038] Simultaneously, when the push rod 15 moves, it will also drive the two connecting rods 13 to move. When the connecting rods 13 move, they will drive the connecting ring 12 to move. Since one end of the connecting ring 12 is movably connected to several T-shaped baffles 8, during the movement of the connecting ring 12, several T-shaped baffles 8 will move along the through groove 21. At this time, the connecting hole 9 will enter the through groove 21, and the T-shaped baffles 8 will block the through hole 11. At the same time, as the T-shaped baffles 8 move, the connecting hole 9 will enter the second drain hole 17, and the T-shaped baffles 8 will release the blockage of the second drain hole 17. The three-way solenoid valve will start to deliver the clean water source to the guide cavity 4, and finally discharge it into the connecting pipe 2 through the first drain hole 16.

[0039] During the rotation of the connecting pipe 2, the cleaning brush 10 cleans the inner wall of the connecting pipe 2 and the through hole 11. The cleaning water entering the guide cavity 4 is discharged through several first drain holes 16 to rinse the inner wall of the connecting pipe 2 and the through hole 11. The filtered material washed out is carried by the water and discharged into the connecting box 1 through several second drain holes 17, and finally discharged into the external environment through the drain pipe 18. After cleaning is completed, the control telescopic cylinder 14 drives the push rod 15 to move downward. At this time, the hydraulic oil re-enters the reservoir 22. Under the elastic force of the connecting spring 24, the T-shaped rod 26 returns to the initial position. At this time, the cleaning brush 10 retracts and no longer contacts the inner wall of the connecting pipe 2.

[0040] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
