DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.

[0027] Example 1

[0028] A microchannel alternative membrane wastewater treatment device, reference Figure 1 and Figure 2 , including a main body 8. The interior of the main body 8 is hollow and is a drug-adding reaction zone 4. A water inlet 1 is provided at the left end of the main body 8, and a mud outlet 5 is provided at the right end. A drug inlet 2 connected to the drug-adding reaction zone 4 is provided at the upper left end of the main body 8, and a water outlet 6 connected to the drug-adding reaction zone 4 is provided at the lower right end. A multi-layer spiral microchannel replacement membrane 3 is arranged in the main body 8. The two ends of the microchannel replacement membrane 3 are respectively connected to the water inlet 1 and the mud outlet 5. A plurality of pores are provided on the microchannel replacement membrane 3, and the pore diameter is 1 mm. The inner wall of the main body 8 is provided with a baffle group uniformly distributed in a ring shape with the central axis of the main body 8 as the center. The baffle group includes a plurality of baffles 7, and the plurality of baffles 7 are evenly arranged on the inner wall of the main body 8 along the elongation direction of the main body 8.

[0029] Sewage enters the microchannel replacement membrane 3 from the water inlet 1. Under the suction of the water outlet pump, the sewage seeps out from the pores, while the mud residue cannot seep out from the pores because the diameter is larger than the diameter of the pores, thereby achieving mud-water separation. The seeped water fully reacts with the reagent and flows out through the water outlet 6, while the mud residue is discharged through the mud outlet 5. A baffle 7 is set on the inner wall of the body 8. The water flow continuously changes its flow direction under the action of the baffle 7, promoting the full reaction of sewage and reagents.

[0030] Example 2

[0031] As a second embodiment of the present invention, based on Embodiment 1, Figure 3 and Figure 4 , a driving rod 9 is rotatably penetrated on the main body 8 and matches the number and position of the baffles 7 one by one. The driving rod 9 is rotatably penetrated by the baffle 7, and the fixed gear 10 is provided with a through opening matching the driving rod 9. The driving rod 9 is rotatably penetrated by the through opening. The fixed gear 10 is fixedly connected to the baffle 7. A base 11 is provided at the lower end of the driving rod 9. Four support rods 12 are evenly distributed in an annular shape with the fixed gear 10 as the center of the circle are provided on the base 11. A driven gear 13 is rotatably provided on the support rod 12. The four driven gears 13 are all meshed with the fixed gear 10. A vertical stirring rod 14 is provided at the lower end of the base 11. A horizontal stirring rod 15 is provided at the center of the driven gear 13.

[0032] When the driving rod 9 rotates, it drives the base 11 to rotate, and then drives the vertical stirring rod 14 to rotate, thereby generating a vertical stirring vortex to accelerate the mixing of water and medicine. When the base 11 rotates, it drives the driven gear 13 to perform an orbital motion with the fixed gear 10 as the center. Since the fixed gear 10 is fixedly arranged and the driven gear 13 is meshed with the fixed gear 10, the driven gear 13 will generate a rotational motion when performing an orbital motion, thereby driving the horizontal stirring rod 15 to rotate, thereby generating a horizontal stirring vortex to accelerate the mixing of water and medicine.

[0033] The main body 8 is provided with a driving motor 16 matched with each baffle set. A first power gear 17 is provided at the output end of the driving motor 16. A second power gear 18 is provided at the upper end of one of the driving rods 9 in the baffle set, and the second power gear 18 is meshed with the first power gear 17. A transmission sprocket 19 is sleeved on all the driving rods 9, and the plurality of transmission sprockets 19 are connected through a transmission chain 20.

[0034] Example 3

[0035] As a third embodiment of the present invention, based on Embodiment 2, Figure 5 and Figure 6, a telescopic rod 21 detachably connected to the baffle 7 is provided at one end of the fixed gear 10 near the baffle 7. The telescopic rod 21 can be detachably connected to the baffle 7 in that a synchronization groove is provided on the baffle 7, and a synchronization tooth matching the synchronization groove and detachably connected is provided at the end of the telescopic rod 21. Since it is a prior art, no further description will be given here. An annular groove is provided at the through-opening of the fixed gear 10, and a plurality of second notches 25 are evenly provided on the inner wall of the annular groove. First notches 22 matching the number and position of the second notches 25 are evenly provided on the outer wall of the driving rod 9. A return spring 23 in a compressed state is provided on the inner wall of the first notch 22. A pressure ball 24 is provided at one end of the return spring 23, and one end of the pressure ball 24 abuts against the inner wall of the second notch 25.

[0036] When the telescopic rod 21 is connected to the baffle 7, the driving rod 9 rotates at this time. Since the fixed gear 10 is connected to the baffle 7, the driving rod 9 is disengaged from the fixed gear 10. At this time, the rotation of the driving rod 9 can simultaneously drive the vertical stirring rod 14 and the horizontal stirring rod 15 to rotate; when the telescopic rod 21 is separated from the baffle 7, the driving rod 9 rotates at this time. Since the fixed gear 10 is separated from the baffle 7, under the action of the reset spring 23, the driving rod 9 is connected to the fixed gear 10. At this time, the driving rod 9 can only drive the vertical stirring rod 14 to rotate.

[0037] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above description or the technology or knowledge of the relevant field.
