[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 11 , the present invention provides a technical solution: A wastewater treatment system for fluazifop production includes a base frame 1, a first water tank 2 is arranged above the base frame 1, symmetrical water tanks 201 are provided from the upper end surface to the inside of the first water tank 2, and the rear end side walls of the two water tanks 201 are provided with first water outlets 202, and inclined grilles 203 are fixedly installed inside the two water tanks 201, and the rear end height of the grille 203 is flush with the lower end of the first water outlet 202, so that larger impurities in the filtered wastewater can pass through the first water outlet 202, such as Figure 1 and Figure 3 shown.

[0034] Then, a triangular tube 204 is fixedly installed on the rear end surface of the first water tank 2 and outside the two first water outlets 202, and a first filter plate 205 in an inclined state is fixedly installed inside the lower end of the triangular tube 204, and a first discharge pipe 206 is fixedly installed on the outer circumferential surface of the lower end of the triangular tube 204. The first discharge pipe 206 is used to remove impurities. Figure 4 shown.

[0035] A water storage cylinder 207 is fixedly installed at the lower end of the triangular tube 204 for receiving a small amount of discharged waste water. A water pump 208 is fixedly installed at the lower end of the water storage cylinder 207, and a first delivery pipe 209 is fixedly installed on the rear side of the water pump 208. The upper end of the first delivery pipe 209 is generally V-shaped, and the V-shaped opening is connected to the water tank 201. Figure 3 shown.

[0036] During use, wastewater enters the first water tank 2, and the grille 203 performs primary filtration on the wastewater to remove larger impurities in the wastewater. The impurities will be carried by the water source through the first water outlet 202 into the interior of the triangular tube 204, and then filtered again by the first filter plate 205. At this time, the impurities are discharged through the first discharge pipe 206, and the re-filtered wastewater enters the interior of the water storage cylinder 207, and under the action of the water pump 208, passes through the first delivery pipe 209 into the interior of the two water tanks 201, as shown in FIG. Figure 1 and Figure 2 shown.

[0037] Two first water outlet pipes 210 are fixedly installed at the lower end of the first water tank 2, wherein the two first water outlet pipes 210 correspond to the water tank 201 one by one. Figure 3 As shown, filter boxes 4 are fixedly installed at the lower ends of the two first water outlet pipes 210, and a T-shaped support rod 3 is fixedly installed at the inner front ends of the two filter boxes 4. A first motor 301 is fixedly installed at the middle upper end of the T-shaped support rod 3. The first motor 301 is a double-axis motor, and first bevel gears 302 are fixedly installed on the output shafts at both ends of the first motor 301. The first bevel gear 302 is meshed with a second bevel gear 303, and the second bevel gear 303 is rotatably installed on the outer side of the lower end of the first water outlet pipe 210, as shown in FIG. Figure 3 As shown, first sealing plates 304 are rotatably installed at the inner lower ends of the two first water outlet pipes 210, and the two first sealing plates 304 are fixedly connected to the second bevel gear 303 adjacent to the outside (it should be noted that a circle of rubber pads are fixedly installed on the outer circumferential surface of the first sealing plate 304, on the one hand to prevent leakage, on the other hand to avoid the first sealing plate 304 from getting stuck when rotating. The rubber pads can be squeezed, so that the first sealing plate 304 can rotate smoothly). Therefore, in order to ensure the subsequent removal of suspended solids in the wastewater, it is necessary to perform a short-term plugging operation on the first water outlet pipe 210.

[0038] When in use, the first motor 301 is started, the output shaft of the first motor 301 drives the first bevel gear 302 to rotate, the first bevel gear 302 drives the second bevel gear 303 to rotate, and the second bevel gear 303 drives the first sealing plate 304 to rotate, thereby completing the opening and closing operation of the lower end of the first water outlet pipe 210. Figure 3 shown.

[0039] A V-shaped pipe 411 is fixedly installed at the lower ends of the two filter boxes 4. (It should be noted that because it is necessary to remove suspended matter in the wastewater, in order to ensure that the wastewater does not flow away directly, the position where the V-shaped pipe 411 and the filter box 4 are connected also needs to be designed with a structure for opening and closing. Its structure is consistent with the structure of the first sealing plate 304, which is used to temporarily prevent the wastewater in the filter box 4 from entering the interior of the V-shaped pipe 411. Therefore, it is necessary to set the same structure as the lower end of the triangular pipe 204 on the outer side of the V-shaped pipe 411 to throttle the wastewater in the filter box 4. However, the specific structure or other structures can be designed and installed by the construction personnel as needed), and a second filter plate 412 in an inclined state is installed inside the lower end of the V-shaped pipe 411, as well as a second discharge pipe 413 on the outer circumferential surface, and a second delivery pipe 414 is fixedly installed between the lower end of the V-shaped pipe 411 and the lower end of the water pump 208. Figure 2 and Figure 8 shown.

[0040] When in use, wastewater enters the interior of the V-shaped tube 411, the second filter plate 412 filters the wastewater, the impurities in the wastewater are filtered again, and then flow out through the second discharge pipe 413. The wastewater passing through the second filter plate 412 enters the interior of the second discharge pipe 413, enters the interior of the first delivery pipe 209 under the action of the water pump 208, and then returns to the interior of the water tank 201.

[0041] Two main motors 401 are fixedly mounted on the upper end surface of the filter box 4, and first threaded rods 402 are fixedly mounted on the output shafts of the two main motors 401. The first threaded rods 402 are located inside the filter box 4, and an extrusion plate 403 is threadedly mounted on the circumferential surface of the two first threaded rods 402. The upper end surface of the extrusion plate 403 is provided with evenly arranged filter holes 404 from the lower end, such as Figure 7 As shown, secondly, the inner layer of the extrusion plate 403 is in a cavity state, and the adjacent sides of the two extrusion plates 403 are fixedly installed with auxiliary motors 405 of symmetrical devices, and a second threaded rod 406 is fixedly installed on the output shaft of the auxiliary motor 405, and three blocking plates 407 are threadedly installed on the circumferential surface of the second threaded rod 406. Figure 7 As shown, the filter holes 404 are arranged in three rows.

[0042] When in use, the main motor 401 is started, and the output shaft of the main motor 401 rotates with the first threaded rod 402, so that the extrusion plate 403 can be located in the interior of the filter box 4 near the top. When there is too much wastewater in the filter box 4, the auxiliary motor 405 is started, and the output shaft of the auxiliary motor 405 rotates with the second threaded rod 406, and the second threaded rod 406 drives the blocking plate 407 to slide, so as to complete the blocking operation of the filter hole 404. The main motor 401 works in the reverse direction to move the extrusion plate 403 downward. At this time, the suspended matter in the wastewater will move downward under the action of the extrusion plate 403, and will not be suspended on the surface of the wastewater. When the extrusion plate 403 moves to the lowest point, it is ensured that the wastewater above the extrusion plate 403 will not enter the interior of the V-shaped tube 411 in subsequent operations. At this time, according to the above-mentioned structure, the blocking device between the V-shaped tube 411 and the filter box is opened, so that the suspended matter can enter the interior of the V-shaped tube 411 under the action of the wastewater, and the suspended matter can be filtered by the second filter plate 412.

[0043] Then, a circular structural hole is opened from the outer side to the inside of the two filters 4, and a cavity groove 408 is opened inside the through hole, such as Figure 6As shown, a telescopic pump 409 is fixedly installed symmetrically at the front and rear ends of the outer side of the filter box 4, and a semicircular plate 410 is fixedly installed on the telescopic rod of the telescopic pump 409. The two semicircular plates 410 can block the circular through hole, so that the waste water inside the filter box 4 cannot enter the inside of the outlet pipe 5 fixedly installed on the outer side. Figure 2 As shown, the wastewater in the filter box 4 can enter the outlet pipe 5 only after the removal of the suspended matter is completed.

[0044] The lower end of the water outlet pipe 5 is fixedly mounted with an upper connecting platform 501 of a truncated cone structure, and a lower connecting platform 505 is arranged below the upper connecting platform 501, and three filter cartridges 502 are arranged between the upper connecting platform 501 and the lower connecting platform 505, and the position where two filter cartridges 502 are attached is sealed by two symmetrical arc-shaped lock buckles 504, such as Fig. 9 As shown, the positions where the upper connecting platform 501, the lower connecting platform 505 and the filter cartridge 502 are fitted are also sealed with lock buckles 504, and activated adsorption carbon plates 503 are fixedly installed inside the filter cartridge 502. The activated adsorption carbon plates 503 can adsorb trace elements and heavy metals in the wastewater, further improving the filtering effect, and the filter cartridge 502 can be replaced in a timely manner under the action of the lock buckles 504.

[0045] Two cavity tubes 605 are transversely fixedly installed at the center of the upper end of the base frame 1, a second motor 6 is fixedly installed at the center of the upper part of the base frame 1, a slide rod 601 is fixedly installed on the output shaft of the second motor 6, a driving rod 602 is slidably installed inside the slide rod 601, the rear end of the driving rod 602 is located on the outside of the slide rod 601, a connecting rod 603 is fixedly installed at the rear end of the driving rod 602, extrusion rods 604 are fixedly installed at both ends of the connecting rod 603, and the left and right extrusion rods 604 are slidably installed inside the cavity tube 605, and the cavity tube 605 is fixedly connected to the adjacent lower connecting platform 505 and is in a through state, secondly, a threaded groove 606 is opened from the outer side surface of the cavity tube 605 to the inside, and a threaded head 607 is rotatably installed inside the threaded groove 606, a jacket 608 is fixedly installed on the outside of the threaded head 607, and an RO membrane 609 is fixedly installed inside the jacket 608, as shown in FIG. Fig.11 shown.

[0046] When in use, the second motor 6 is started, and the output shaft of the second motor 6 rotates in a fan shape with the slide rod 601. The slide rod 601 allows the driving rod 602 to slide and drives the connecting rod 603 to move horizontally and linearly. The connecting rod 603 drives the squeezing rods 604 at the left and right ends to slide inside the cavity tube 605, so that the wastewater passing through the lower connecting platform 505 and entering the cavity tube 605 will be squeezed. The squeezed wastewater passes through the RO membrane 609 one by one. The gap of the RO membrane 609 is very small and can only allow water to pass through, thereby completing the final filtration operation of the wastewater. It should be noted that when squeezing the wastewater, the squeezing rod 604 blocks the position where the cavity tube 605 and the lower connecting platform 505 are connected. Only after resetting, the cavity tube 605 and the lower connecting platform 505 are in a connected state, so the wastewater enters the cavity tube 605 again.

[0047] Working principle: First, wastewater enters the water tank 201 in the first water tank 2 for primary filtration, and the filtered wastewater passes through the first outlet pipe 210 and enters the interior of the filter box 4.

[0048] A small amount of waste water and impurities pass through the first water outlet 202 into the interior of the triangular tube 204 , and then are filtered through the first filter plate 205 . The filtered waste water enters the water storage cylinder 207 , and the rest flows out through the first discharge pipe 206 .

[0049] The water pump 208 is started to allow the waste water in the water storage cylinder 207 to enter the first delivery pipe 209 and then return to the inside of the water tank 201.

[0050] The wastewater entering the filter box 4 starts the auxiliary motor 405 , and the output shaft of the auxiliary motor 405 rotates with the second threaded rod 406 , so that the blocking plate 407 blocks the filter hole 404 .

[0051] The main motor 401 is started, and the output shaft of the main motor 401 rotates with the first threaded rod 402, so that the extrusion plate 403 moves downward to complete the cleaning operation of the suspended matter, allowing the suspended matter and a small amount of waste water to enter the interior of the V-shaped tube 411, and then the suspended matter is filtered by the second filter plate 412. The filtered waste water enters the interior of the second conveying pipe 414, and returns to the interior of the water tank 201 under the action of the water pump 208, and the suspended matter flows away through the second discharge pipe 413.

[0052] The telescopic pump 409 is started to allow the wastewater in the filter box 4 to enter the outlet pipe 5 and then enter the filter cartridge 502 . The trace elements and heavy metals in the wastewater are adsorbed by the activated adsorption carbon plate 503 .

[0053] The wastewater then enters the interior of the hollow tube 605 through the lower connecting platform 505 .

[0054] Start the second motor 6. Start the second motor 6. The output shaft of the second motor 6 drives the slide rod 601 to rotate in a fan shape. The slide rod 601 allows the driving rod 602 to slide and drives the connecting rod 603 to move horizontally. The connecting rod 603 drives the squeezing rods 604 at the left and right ends to slide inside the cavity tube 605. In this way, the wastewater passing through the lower connecting platform 505 and entering the cavity tube 605 will be squeezed, and the squeezed wastewater will pass through the RO membrane 609 one by one.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
