[0028] 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.

[0029] See also Figure 1-5 As shown, the present invention provides a technical solution: a wastewater separation and treatment device for preparing benzoylurea pesticides, comprising a treatment box 1 and a drain pipe 9 arranged on the treatment box 1, a sieve plate 2 is rotatably connected to the treatment box 1, an open groove is formed on the side of the treatment box 1, a U-shaped shell cover 4 is slidably arranged on the side of the sieve plate 2, and the floating matter in the wastewater is intercepted by the sieve plate 2 and slides into the U-shaped shell cover 4 through the open groove, and a bending frame 3 is fixed on the side end of the treatment box 1 to cooperate with the U-shaped shell cover 4 to close the open groove.

[0030] The free end of the sieve plate 2 is placed in the open slot and is placed at an angle. Wastewater is poured into the treatment box 1 through the opening at the top of the treatment box 1. When the wastewater passes through the sieve plate 2, impurities floating in the wastewater will be intercepted on the upper side of the sieve plate 2. The intercepted impurities slide along the inclined surface of the sieve plate 2 into the U-shaped shell 4 under the scouring effect of the water flow. The bending frame 3 and the U-shaped shell 4 form a closed structure for the open slot, which is used to collect and store floating impurities washed down by the sieve plate 2.

[0031] While the wastewater is poured out from the open top of the treatment box 1, a flocculant is added into the treatment box 1 to aggregate the suspended particles in the wastewater into larger flocs, so that they can be separated from the wastewater by sedimentation.

[0032] A support plate 8 is vertically slidable in the processing box 1. A screw 10 and a drive motor 11 for controlling the rotation of the screw 10 are installed in the processing box 1. A transmission component is provided on the outside of the processing box 1, and a linkage component is provided on the inside of the processing box 1. When the screw 10 rotates, the support plate 8 is first lifted upward along the processing box 1 to be flush with the opening groove under the action of the linkage component, and then the U-shaped shell cover 4 slides away from the processing box 1 under the action of the transmission component.

[0033] A frame is formed in the inner wall of the treatment box 1 to cooperate with the bottom of the support plate 8. The fit between the support plate 8 and the frame can prevent the sewage from leaking out of the treatment box 1 when it is settled. In addition, a rubber ring is provided on the side wall of the support plate 8 that slides in fit with the inner wall of the treatment box 1 to prevent the sewage from leaking out when the support plate 8 slides along the treatment box 1.

[0034] After the wastewater has completed sedimentation in the treatment box 1, the screw 10 is controlled to rotate by the driving motor 11, so that the support plate 8 first moves upward along the treatment box 1 under the action of the linkage component. During this process, the water that overflows the drain pipe 9 will be discharged outward from the treatment box 1 until the support plate 8 reaches a position flush with the open groove. At this time, the wastewater sediment remains on the support plate 8. Subsequently, by controlling the continued rotation of the screw 10, the U-shaped shell cover 4 will drive the U-shaped scraper 5 to move horizontally under the action of the transmission component. During this process, the floating sediment accumulated on the U-shaped shell cover 4 will be scraped off the U-shaped shell cover 4 by the bending frame 3. At the same time, the wastewater sediment on the support plate 8 will also be scraped out of the treatment box 1 from the open groove under the action of the U-shaped scraper 5, thereby cleaning the floating impurities and precipitated impurities in the wastewater at the same time, thereby achieving the purpose of improving the cleaning efficiency of the separated impurities after the wastewater treatment.

[0035] A filter screen is provided at the passage of the drain pipe 9 to limit the precipitated impurities in the wastewater from being discharged outward along the drain pipe 9, so as to intercept the precipitated impurities.

[0036] A U-shaped scraper 5 is fixedly provided on the U-shaped shell cover 4 for scraping and cleaning the sediment on the surface of the support plate 8. An air nozzle 6 is formed on the inner wall of the U-shaped scraper 5. A pumping component is provided on the processing box 1. When the support plate 8 is lifted upward along the processing box 1, the air nozzle 6 blows air toward the screen plate 2 under the action of the pumping component.

[0037] A notch is formed in the inner wall of the processing box 1 for the U-shaped scraper 5 to slide into, so that when the U-shaped shell 4 is in a closed state with the bending frame 3, the inner wall of the U-shaped scraper 5 remains flush with the inner wall of the processing box 1.

[0038] When the support plate 8 moves upward along the processing box 1 under the action of the linkage component, the air nozzle 6 will blow air to the screen plate 2 under the action of the pump air component to blow away the impurities adhering to the screen plate 2. When the U-shaped scraper 5 moves horizontally with the U-shaped shell 4, the lower end of the U-shaped scraper 5 scrapes the precipitated impurities on the support plate 8, and the upper end of the U-shaped scraper 5 acts on the top of the screen plate 2, driving the screen plate 2 to rotate and lift, providing space for scraping away the precipitated impurities.

[0039] Specifically, Figure 3-5 As shown, the linkage component includes a transverse axis 14 rotatably connected in the processing box 1, and a guide assembly driving the transverse axis 14 to rotate. A transmission arm 16 coaxially fixed with the transverse axis 14 is rotatably arranged in the processing box 1, and the free end of the transmission arm 16 is rotatably connected to the support plate 8.

[0040] The transmission arm 16 is composed of two arms of equal length connected in rotation. When the transmission arm 16 rotates with the horizontal axis 14, the transmission arm 16 rotates to extend or fold, driving the support plate 8 connected in rotation to its free end to move vertically along the processing box 1.

[0041] The guide assembly includes a slide arm 12 slidably arranged on the outside of the horizontal shaft 14, and the slide arm 12 is screwed and connected with the screw 10. A protrusion 13 is formed on the inner wall of the slide arm 12, and a slideway 15 is formed on the side wall of the horizontal shaft 14 to slide with the protrusion 13. The slideway 15 is composed of a spiral segment and a straight segment. When the protrusion 13 slides along the spiral segment, the horizontal shaft 14 rotates under the pressure of the protrusion 13 on the inner wall of the spiral segment. When the protrusion 13 slides along the straight segment, the horizontal shaft 14 stops rotating.

[0042] There are two slide arms 12 arranged in the processing box 1, and the screw rod 10 is a transmission for the two slide arms 12, and its external thread is bidirectional. When the two slide arms 12 move synchronously towards each other, the protrusion 13 fixed in the slide arm 12 will first slide along the spiral section of the slideway 15, and at this time, the protrusion 13 presses the spiral section to drive the horizontal shaft 14 to rotate. As the two slide arms 12 continue to move towards each other, the protrusion 13 slides into the straight section, and the horizontal shaft 14 stops rotating. At this time, the upper end surface of the support plate 8 will remain flush with the open groove.

[0043] Specifically, Figure 1-4 As shown, the transmission component includes a slider 27 slidably connected to the outer end of the processing box 1, and a traction assembly driving the slider 27 to slide vertically. The outer side of the U-shaped shell 4 is rotatably connected to a first swing arm 28, and a second swing arm 30 is slidably connected in the first swing arm 28, and the second swing arm 30 is rotatably connected to the slider 27. A groove is formed in the first swing arm 28 to cooperate with the sliding of the second swing arm 30, and a round block 29 is fixed in the groove, and a sliding groove 31 is formed in the second swing arm 30 to cooperate with the sliding of the round block 29.

[0044] When the slider 27 slides upward along the processing box 1, the second rotary arm 30 rotatably connected to the outside of the slider 27 will first slide along the groove of the first rotary arm 28, and during this process, the U-shaped shell cover 4 remains stationary relative to the processing box 1. Until the end of the second rotary arm 30 contacts the inner wall of the groove, at this time, as the slider 27 continues to slide upward, the first rotary arm 28 presses the second rotary arm 30, driving the U-shaped shell cover 4 rotatably connected to the second rotary arm 30 to slide outward along the processing box 1, and pushing the U-shaped shell cover 4 away from the processing box 1.

[0045] When the slider 27 slides downward along the processing box 1, the second swing arm 30 first slides along the groove of the first swing arm 28. During this process, the round block 29 slides along the slide groove 31. As the second swing arm 30 is extended to the position relative to the first swing arm 28, the round block 29 will pull the inner wall of the slide groove 31 to drive the U-shaped shell cover 4 rotatably connected to the second swing arm 30 to slide closer to the processing box 1.

[0046] The traction assembly includes two wheels 25 rotatably connected to the outside of the processing box 1 , and the outer engagement sleeves of the two wheels 25 are provided with chains 26 fixed to the slider 27 , and one of the wheels 25 is coaxially fixed to the screw 10 .

[0047] When the screw rod 10 rotates under the action of the driving motor 11 , the wheel disc 25 coaxially fixed with the screw rod 10 rotates synchronously. At this time, the chain 26 drives the slider 27 fixed thereto to move in the vertical direction under the action of the two wheel discs 25 .

[0048] Specifically, Figure 2-4 As shown, the air pump component includes an air cylinder 24 fixed to the outer end of the processing box 1, a piston 20 slidably connected in the air cylinder 24, and a horizontal thrust assembly that drives the piston 20 to move. An air pipe 7 for use with an air nozzle 6 is connected between the air cylinder 24 and the U-shaped scraper 5.

[0049] A plurality of air nozzles 6 are linearly distributed on the inner end surface of the U-shaped scraper 5 , and an air cavity is formed in the U-shaped scraper 5 , which is connected with the air pipe 7 and the plurality of air nozzles 6 .

[0050] When the piston 20 moves along the inside of the air cylinder 24 toward the processing box 1, the air stored in the air cylinder 24 will be filled into the air cavity in the U-shaped scraper 5 through the air pipe 7, and finally act on the screen plate 2 through the air nozzle 6.

[0051] The horizontal push assembly includes a sliding frame 18 slidably arranged in the processing box 1 , a cross bar 19 slidingly penetrating the processing box 1 is fixedly arranged between the sliding frame 18 and the piston 20 , and a support arm 17 is rotatably connected between the sliding frame 18 and the transmission arm 16 .

[0052] The transmission arm 16 fixed coaxially with the transverse axis 14 is rotatably connected to the support arm 17 . When the transmission arm 16 is rotated and opened, the support arm 17 pulls the cross bar 19 through the sliding frame 18 to drive the piston 20 to slide toward the processing box 1 .

[0053] When the transmission arm 16 is rotated and folded, the support arm 17 will push the cross bar 19 through the sliding frame 18, driving the piston 20 to slide away from the processing box 1.

[0054] Specifically, Figure 2 and Figure 3 As shown, a horizontal push frame 21 for guiding the air pipe 7 is slidably provided on the outer side of the processing box 1, and a limiting frame 22 for sliding with the horizontal push frame 21 is fixed on the outer end of the processing box 1. The outer side of the limiting frame 22 is sleeved with a compression spring 23 for pressing the horizontal push frame 21 outward.

[0055] When the U-shaped scraper 5 slides toward the open groove of the processing box 1, the air pipe 7 will extend into the processing box 1 along with the sliding of the U-shaped scraper 5. At this time, the horizontal push frame 21 will slide toward the processing box 1 along the limit frame 22 under the pulling action of the air pipe 7. When the U-shaped scraper 5 slides and resets along the processing box 1, the horizontal push frame 21 will push the outer wall of the air pipe 7 under the action of the compression spring 23, and pull the air pipe 7 out of the processing box 1, which is conducive to the sliding reset of the U-shaped scraper 5.

[0056] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
