[0011] As a preferred technical solution of the present invention, the trachea is retractable.

[0012] A method for using a wastewater treatment device for a spraying line comprises the following steps:

[0013] S1. The user passes the wastewater to be treated into the treatment box, and then controls the output shaft of the servo motor to rotate. The rotation of the output shaft of the servo motor drives the column gear 2 to rotate. The rotation of the column gear 2 drives the column gear 1 and the column gear 3 to rotate. The column gear 3 rotates idly. The rotation of the column gear 1 drives the overrunning clutch 1 to rotate. The rotation of the overrunning clutch 1 drives the stirring rod to rotate. The rotation of the stirring rod will drive the wastewater in the treatment box to rotate slowly.

[0014] S2. The user gradually drops reagents into the treatment box. The rotation of the wastewater can react with the reagents more fully. The impurities precipitated by the reaction in the wastewater will be free near the inner wall of the treatment box during the slow rotation of the wastewater. The impurities will be intercepted by the filter baffle as the wastewater rotates. The rotation of the stirring rod will drive the lifting plate to move back and forth. The reciprocating movement of the lifting plate will drive the scraper rod to extend into or out of the treatment box. When the scraper rod extends into the treatment box, it will scrape the impurities filtered out of the filter baffle to above the sewage discharge hole of the treatment box, and the impurities will fall into the storage frame through the sewage discharge hole of the treatment box.

[0015] S3. The user controls the servo motor output shaft to reverse a certain angle. The reversal of the servo motor output shaft drives the column gear 2 to reverse. The reversal of the column gear 2 drives the column gear 1 and the column gear 3 to reverse. The column gear 1 reverses. The rotation of the column gear 3 drives the overrunning clutch 2 to rotate. The rotation of the overrunning clutch 2 drives the rotating column to rotate. The rotation of the rotating column drives the partition 1 and the partition 2 to rotate. The torsion spring 1 is twisted. The rotation of the partition 1 will block the sewage discharge hole of the processing box. Then the partition 2 will block the water outlet of the storage frame, so that the processing box and the storage frame are isolated, and the impurities in the storage frame are discharged from the storage frame through the water outlet of the storage frame.

[0016] S4. During the rotation of partition 1, partition 1 will drive the gear rod to move, and the gear rod will mesh with column gear 4 during the movement, so that column gear 4 drives the top plate to rotate in the direction close to the filter baffle. Torsion spring 2 is twisted, and the gear rod will not be separated from column gear 4. During the rotation of the top plate, the stainless steel brush on the top plate will pass through the mesh of the filter baffle, thereby clearing the mesh of the filter baffle.

[0017] S5. The movement of the partition will drive the airbag to move. When the six airbags move to the bottom of the sewage discharge hole of the treatment box respectively, the partition will squeeze the air pressure plate. The air pressure plate will extend out of the air frame due to the squeezing. The pressure spring will be compressed, so that the gas in the air frame will be discharged into the airbag through the air pipe, thereby making the airbag expand. The expanded airbag will fit tightly with the treatment box.

[0018] Beneficial effects: 1. The rotation of the stirring rod will drive the wastewater in the treatment box to rotate slowly. The rotation of the wastewater can react with the reagent more fully. The impurities precipitated from the reaction in the wastewater will be free near the inner wall of the treatment box during the slow rotation of the wastewater. The impurities will be intercepted by the filter baffle as the wastewater rotates. The scraper rod will scrape the impurities filtered out from the filter baffle to the top of the sewage hole of the treatment box during the process of extending into the treatment box. The impurities will fall into the storage frame through the sewage hole of the treatment box. In this way, the wastewater can react with the reagent better, and the precipitated impurities can be separated from the wastewater in time, thereby improving the reaction efficiency of the wastewater and the reagent.

[0019] 2. During the movement of the gear rod, it will mesh with column gear four, so that column gear four drives the top plate to rotate in the direction close to the filter baffle. The torsion spring two is twisted, and the gear rod will not be separated from the column gear four. During the rotation of the top plate, the stainless steel brush on the top plate will pass through the mesh of the filter baffle, thereby dredging the mesh of the filter baffle. In this way, the mesh of the filter baffle can be dredged, thereby improving the efficiency of intercepting impurities.

[0020] 3. The movement of the partition drives the airbag to move. When the six airbags move to the bottom of the sewage discharge hole of the treatment box respectively, the partition will squeeze the air pressure plate. The air pressure plate will extend out of the air frame due to the squeezing, and the pressure spring will be compressed, so that the gas in the air frame will be discharged into the airbag through the air pipe, thereby making the airbag expand. The expanded airbag will fit tightly with the treatment box, thereby improving the sealing effect of the sewage discharge hole of the treatment box. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The stirring component includes a stirring rod 61, a conical disk 62, an overrunning clutch 1 63, a column gear 1 64, a servo motor 65 and a column gear 2 66. The sealing plate 3 is rotatably connected with the stirring rod 61, and the stirring rod 61 is used to drive the wastewater in the treatment box 2 to rotate slowly. The stirring rod 61 extends into the treatment box 2 and is rotatably connected to the treatment box 2. The stirring rod 61 is provided with a bidirectional thread. The treatment box 2 is fixedly connected with a conical disk 62, and the stirring rod 61 and the conical disk 62 are rotatably connected. The stirring rod 61 is fixedly connected with an overrunning clutch 1 63, and the overrunning clutch 1 63 is fixedly connected with a column gear 1 64. The mounting frame 1 is fixedly connected with a servo motor 65, and the output shaft of the servo motor 65 is fixedly connected with a column gear 2 66, and the column gear 2 66 is meshed with the column gear 1 64.

[0042] The filtering component includes a filtering baffle 71, a lifting plate 72 and a scraper rod 73. Six filtering baffles 71 are fixedly connected to the processing box 2. The lifting plate 72 is threadedly connected to the stirring rod 61. Six scraper rods 73 are slidably connected to the processing box 2. The scraper rods 73 are used to scrape off impurities attached to the filtering baffles 71. The six scraper rods 73 are fixedly connected to the lifting plate 72.

[0043] The impurity discharge components include a partition 81, a rotating column 82, a partition 83, an overrunning clutch 84 and a column gear 3 85. A partition 81 is clamped between the processing box 2 and the sealing plate 3. The partition 81 is rotatably connected to the processing box 2. A rotating column 82 is rotatably connected to the mounting frame 1. The rotating column 82 and the sealing plate 3 are rotatably connected. A partition 83 is rotatably connected to the storage frame 4. The partition 83 and the rotating column 82 are fixedly connected. The rotating column 82 is fixedly connected with an overrunning clutch 84. The overrunning clutch 84 is fixedly connected with a column gear 3 85. The column gear 3 85 is used to drive the rotating column 82 to rotate. The column gear 3 85 is meshed with the column gear 2 66. A torsion spring 86 is connected between the partition 83 and the mounting frame 1.

[0044] At first, the partition 1 81 does not block the sewage discharge hole of the treatment box 2, and the partition 2 83 blocks the water outlet of the storage frame 4. The user passes the wastewater to be treated into the treatment box 2. Then, the user controls the output shaft of the servo motor 65 to rotate. The rotation of the output shaft of the servo motor 65 drives the column gear 2 66 to rotate. The rotation of the column gear 2 66 drives the column gear 1 64 and the column gear 3 85 to rotate. The column gear 3 85 rotates idly. The rotation of the column gear 1 64 drives the stirring rod 61 to rotate through the overrunning clutch 1 63. The rotation of the stirring rod 61 drives the wastewater in the treatment box 2 to rotate slowly. Subsequently, the user gradually drips reagents into the treatment box 2, and the wastewater rotates. The impurities precipitated from the reaction in the wastewater will be free near the inner wall of the treatment box 2 during the slow rotation of the wastewater. The impurities will be intercepted by the filter baffle 71 during the rotation of the wastewater. While the stirring rod 61 rotates, the bidirectional thread of the stirring rod 61 will drive the lifting plate 72 to move back and forth. During the reciprocating movement of the lifting plate 72, the scraper rod 73 will be driven to extend into or out of the treatment box 2. During the process of the scraper rod 73 extending into the treatment box 2, the impurities filtered out from the filter baffle 71 will be scraped to the top of the sewage discharge hole of the treatment box 2. The impurities will fall into the storage frame 4 through the sewage discharge hole of the treatment box 2, and then the scraper rod 73 will move in the opposite direction. After a period of reciprocating treatment, the user controls the output shaft of the servo motor 65 to reverse a certain angle, and the output shaft of the servo motor 65 reverses to drive the column gear 2 66 to reverse, and the column gear 2 66 reverses to drive the column gear 1 64 and the column gear 3 85 to reverse, and the column gear 1 64 reverses, and the column gear 3 85 reverses through the overrunning clutch 2 to drive the rotating column 82 to rotate, and the rotation of the rotating column 82 will drive the partition 1 81 and the partition 2 83 to rotate, and the torsion spring 1 86 is twisted, and the rotation of the partition 1 81 will block the sewage discharge hole of the processing box 2, and then the partition 2 83 will block the water outlet of the storage frame 4, so that the processing box 2 and the storage frame 4 are isolated. The impurities in the storage frame 4 are discharged from the storage frame 4 through the water outlet of the storage frame 4. After the impurities in the storage frame 4 are discharged, the user controls the servo motor 65 to reverse again, the column gear three 85 idles, the torsion spring resets to drive the rotating column 82 to reverse and reset, the rotating column 82 reverses to drive the partition 1 81 and the partition 2 83 to reset, and this is repeated three times. The user turns off the servo motor 65, and the user opens the water outlet pipe 5. The wastewater in the treatment box 2 is discharged from the treatment box 2 through the water outlet pipe 5. In this way, the wastewater can react with the reagent better, and the precipitated impurities can be separated from the wastewater in time, thereby improving the reaction efficiency of the wastewater and the reagent.

[0045] Embodiment 2: Based on embodiment 1, Figure 2-Figure 14As shown, it also includes a filtering auxiliary component. The processing box 2 is provided with a filtering auxiliary component, which is used to remove impurities blocked on the filter baffle 71. The filtering auxiliary component includes a top plate 91, a gear rod 92, a column gear four 93 and a torsion spring two 94. Six top plates 91 are rotatably connected to the processing box 2. The top plates 91 are used to dredge the mesh of the filter baffle 71. Each top plate 91 is fixedly connected to a column gear four 93, and six gear rods 92 are fixedly connected to the partition one 81. A torsion spring two 94 is connected between each top plate 91 and the processing box 2.

[0046] A plurality of soft stainless steel brushes are provided on the top plate 91 .

[0047] During the rotation of partition 81, partition 81 will drive gear rod 92 to move, and gear rod 92 will mesh with column gear four 93 during the movement, so that column gear four 93 drives top plate 91 to rotate in the direction close to filter baffle 71, torsion spring two 94 is twisted, gear rod 92 will not disengage from column gear four 93, and during the rotation of top plate 91, the stainless steel brush on top plate 91 will pass through the mesh of filter baffle 71, thereby dredging the mesh of filter baffle 71, and the reset of partition 81 drives gear rod 92 to reset, and the reset of gear rod 92 drives column gear four 93 to reset, and the reset of column gear four 93 drives top plate 91 to reset, and torsion spring two 94 is reset. In this way, the mesh of filter baffle 71 can be dredged, thereby improving the efficiency of intercepting impurities.

[0048] Embodiment 3: Based on embodiment 2, Figure 15-17 As shown, it also includes a sealing component. A sealing component is provided on the sealing plate 3. The sealing component is used to strengthen the sealing between the partition 81 and the processing box 2. The sealing component includes an air frame 101, an air bag 102, an air pipe 103 and a pressure plate 104. The sealing plate 3 is fixedly connected with the air frame 101. Six air bags 102 are fixedly connected to the partition 81. The air bags 102 are used to improve the sealing between the partition 81 and the processing box 2. An air pipe 103 is connected between each air bag 102 and the air frame 101. Each air pipe 103 partially extends into the partition 81. The air frame 101 is slidably connected with the pressure plate 104. A plurality of pressure springs 105 are connected between the air frame 101 and the pressure plate 104.

[0049] The air tube 103 has elasticity.

[0050] When the partition 81 rotates to block the drain hole of the processing box 2, the movement of the partition 81 drives the airbag 102 to move. When the six airbags 102 move to the bottom of the drain hole of the processing box 2 respectively, the partition 81 will squeeze the air pressure plate 104. The air pressure plate 104 will be squeezed and extend out of the air frame 101. The pressure spring 105 is compressed, so that the gas in the air frame 101 will be discharged into the airbag 102 through the air pipe 103, thereby allowing the airbag 102 to expand. The expansion of the airbag 102 will fit closely with the processing box 2, thereby improving the sealing effect of the drain hole of the processing box 2. The partition 81 is reversed, the partition 81 and the air pressure plate 104 are separated, the pressure spring 105 is reset, driving the compressed air plate 104 to reset, and the air in the airbag 102 is drawn back into the air frame 101.

[0051] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.

9. A method for using a wastewater treatment device for a spraying line as claimed in claim 7, comprising the following steps: S1. The user passes the wastewater to be treated into the treatment box (2), and then controls the output shaft of the servo motor (65) to rotate. The rotation of the output shaft of the servo motor (65) drives the column gear 2 (66) to rotate. The column gear 2 (66) drives the column gear 1 (64) and the column gear 3 (85) to rotate. The column gear 3 (85) rotates idly. The rotation of the column gear 1 (64) drives the overrunning clutch 1 (63) to rotate. The rotation of the overrunning clutch 1 (63) drives the stirring rod (61) to rotate. The rotation of the stirring rod (61) drives the wastewater in the treatment box (2) to rotate slowly. S2, the user gradually drips the reagent into the treatment box (2), and the wastewater rotates so that it can react more fully with the reagent. Impurities precipitated by the reaction in the wastewater will be free near the inner wall of the treatment box (2) during the slow rotation of the wastewater. The impurities will be intercepted by the filter baffle (71) during the rotation of the wastewater. The rotation of the stirring rod (61) will drive the lifting plate (72) to move back and forth. The reciprocating movement of the lifting plate (72) will drive the scraper rod (73) to extend into or out of the treatment box (2). When the scraper rod (73) extends into the treatment box (2), it will scrape the impurities filtered out of the filter baffle (71) to the top of the sewage discharge hole of the treatment box (2), and the impurities will fall into the storage frame (4) through the sewage discharge hole of the treatment box (2); S3, the user controls the output shaft of the servo motor (65) to reverse a certain angle, the output shaft of the servo motor (65) reverses and drives the column gear 2 (66) to reverse, the column gear 2 (66) reverses and drives the column gear 1 (64) and the column gear 3 (85) to reverse, the column gear 1 (64) reverses, the column gear 3 (85) rotates and drives the overrunning clutch 2 (84) to rotate, the overrunning clutch 2 (84) rotates and drives the rotating column (82) to rotate, the rotating column (82) rotates and drives the partition 1 (81) and the partition 2 (83) to rotate, the torsion spring 1 (86) is twisted, the partition 1 (81) rotates and blocks the sewage discharge hole of the processing box (2), and then the partition 2 (83) blocks the water outlet of the storage frame (4), so that the processing box (2) and the storage frame (4) are isolated, and the impurities in the storage frame (4) are discharged from the storage frame (4) through the water outlet of the storage frame (4); S4, during the rotation of the partition plate 1 (81), the partition plate 1 (81) will drive the gear rod (92) to move, and during the movement of the gear rod (92), it will mesh with the column gear 4 (93), so that the column gear 4 (93) drives the top plate (91) to rotate in the direction close to the filter baffle (71), the torsion spring 2 (94) is twisted, the gear rod (92) will not be separated from the column gear 4 (93), and during the rotation of the top plate (91), the stainless steel brush on the top plate (91) will pass through the mesh of the filter baffle (71), thereby clearing the mesh of the filter baffle (71); S5. The movement of the partition plate 1 (81) will drive the airbag (102) to move. When the six airbags (102) move to the bottom of the sewage discharge hole of the processing box (2), the partition plate 1 (81) will squeeze the air pressure plate (104). The air pressure plate (104) will be squeezed and extend out of the air frame (101). The pressure spring (105) is compressed, so that the gas in the air frame (101) will be discharged into the airbag (102) through the air pipe (103), thereby making the airbag (102) expand. The expanded airbag (102) will fit tightly with the processing box (2).
