[0026] Example 1, please refer to Figure 1 - Figure 5The present embodiment provides an online chemical waste liquid recovery device, comprising a recovery box 1; a support base 2, the support base 2 being fixedly connected to the interior of the recovery box 1; a water inlet pipe 3, the water inlet pipe 3 being fixedly connected to the side wall of the recovery box 1, and the water inlet pipe 3 being responsible for introducing the chemical waste liquid into the interior of the recovery box 1; a stirring shaft 41, the stirring shaft 41 rotatingly penetrating the upper side box body of the recovery box 1; a stirring plate 42, the stirring plate 42 being fixedly connected to the outer wall of the stirring shaft 41, which can effectively accelerate the mixing of substances in the waste liquid through stirring, improve the treatment effect, and avoid waste liquid sedimentation; The inner wall of the recycling box 1 is fixedly connected with a filter frame 51, and the filter frame 51 filters out solid impurities in the waste liquid through the internal filtering mechanism. The upper end of the recycling box 1 is fixedly connected with an L-shaped mounting plate 52, and the inner side of the L-shaped mounting plate 52 is rotatably connected with a rotating shaft 520. The bottom of the rotating shaft 520 is fixedly connected with a rotating plate 53, and the bottom of the rotating plate 53 is fixedly connected with a sliding rod 54. The upper end of the recycling box 1 is provided with a tooth plate 55, and the upper end of the tooth plate 55 is fixedly connected with a movable frame 56. The lower end of the sliding rod 54 is slidably connected to the inside of the movable frame 56. The outer wall of the stirring shaft 41 is located at the upper part of the recycling box 1 and is fixedly provided with a gear 57. The gear 57 meshes with the tooth plate 55. The inner wall of the filter frame 51 is fixedly connected with the outer wall of the recycling box 1. A scraper 59 is slidably connected to the wall of the filter frame 51. The scraper 59 is used to clean impurities from the inner wall of the filter frame 51. Openings 510 and a collection chamber 511 are respectively defined on both sides and in the middle of the scraper 59. A connecting plate 512 is fixedly connected to the outer wall of the scraper 59. A fixed block 513 is fixedly connected to the upper end of the filter frame 51. A fixed rod 514 is fixedly connected to the outer wall of the fixed block 513. The connecting plate 512 slidably connects to the outer wall of the fixed rod 514. A discharge port 516 is defined on the side of the recovery box 1 for discharging cleaned impurities. Sliding openings are defined on both sides of the filter frame 51, and blocks 517 are slidably connected to the inner walls of these openings. Two push rods 518 are fixedly connected to the outer wall of the agitator shaft 41. A slide rail 58 is fixedly connected to the upper end of the recovery box 1. A toothed plate 55 is slidably connected to the outer wall of the slide rail 58. A spring 515 is movably sleeved on the outer wall of the fixed rod 514, with both ends of the spring 515 contacting the fixed block 513 and the connecting plate 512, respectively. An elastic telescopic rod 519 is fixedly connected to the inner wall of the recycling bin 1. The other end of the elastic telescopic rod 519 is fixedly connected to the stopper 517. A spring 515 helps the connecting plate 512 return to its original position, ensuring that the scraper 59 can return to its original position. The elastic telescopic rod 519 supports the return of the stopper 517. The push rod 518 is at the same level as the connecting plate 512. The scraper 59 has inclined surfaces on both sides below the opening 510.

[0027] During use, sewage first enters the interior of the recycling box 1 through the water inlet pipe 3, and is poured into the interior of the filter frame 51 from top to bottom, and then the sewage is filtered by the filter frame 51, and then flows to the lower part of the recycling box 1. At the same time, treatment agents are added into the interior of the recycling box 1 through the dosing port, and then the motor can be started to drive the rotating shaft 520 to rotate counterclockwise, and then the rotating plate 53 at the bottom of the rotating shaft 520 will rotate accordingly, and then the sliding rod 54 at the bottom of the rotating plate 53 will rotate around the rotating shaft 520. At the same time, since the sliding rod 54 slides inside the movable frame 56, the rotation of the sliding rod 54 can drive the movable frame 56 to move back and forth, and then the toothed plate 55 at the bottom of the movable frame 56 The tooth plate 55 will drive the gear 57 meshing with it to rotate forward and reverse, and then the stirring shaft 41 will rotate forward and reverse and drive the stirring plate 42 to rotate at the same time, and then the stirring plate 42 will mix the sewage and the medicine inside the recycling box 1, and the forward and reverse rotation can improve the mixing effect. At the same time, the rotation of the stirring shaft 41 can drive the push rod 518 on its outer wall to rotate. When the push rod 518 rotates to a certain angle, it will contact the connecting plate 512. At this time, the push rod 518 continues to rotate, which will push the connecting plate 512 to slide on the outer wall of the fixed rod 514. Then the connecting plate 512 can also drive the scraper 59 from the filter The middle part of the frame 51 moves to both sides, so that the inner wall of the filter frame 51 can be cleaned. At the same time, since the parts of the scraper 59 on both sides that are lower than the through opening 510 are set as inclined surfaces, when the scraper 59 is cleaning, most of the impurities will enter the interior of the collection chamber 511 along the inclined surface on the lower side of the scraper 59 through the through opening 510, and the sewage will not enter the interior of the collection chamber 511 because it is poured into the interior of the filter frame 51 and due to the inclined design of the scraper 59. When the scraper 59 moves close to the inner wall of the filter frame 51, the side of the scraper 59 will squeeze the stopper 517, causing it to slide to the outside of the sliding opening, and then the discharge port 516 blocked by the stopper 517 will be opened, and the collection chamber 51 The impurities collected inside the filter frame 51 will fall out through the discharge port 516. When the scraper 59 squeezes the stopper 517, the scraper 59 itself can block the sewage, thereby preventing the sewage from flowing out through the discharge port 516. When the scraper 59 moves to the maximum stroke, the push rod 518 will also leave the outer wall of the connecting plate 512. At this time, under the action of the spring 515, the connecting plate 512 can be pushed to quickly return to its original position, and the scraper 59 will also return to the middle of the filter frame 51. The stopper 517 will also be quickly returned to its original position under the action of the elastic telescopic rod 519. Since the stirring shaft 41 rotates forward and reverse, the connecting plate 512 will drive the scraper 59 to move from the middle of the filter frame 51 to both sides.

[0028] Example 2, please refer to Figure 1 - Figure 7On the basis of Example 1, the outer wall of the recycling box 1 is equipped with an adjustable drainage assembly 6, which includes a ratchet 61. The ratchet 61 is fixedly sleeved on the outer wall of the rotating shaft 520. The inner side of the L-shaped mounting plate 52 is rotatably connected to the transmission wheel A62. The inner wall of the transmission wheel A62 is hinged with a pawl 63. An elastic rope is provided between the pawl 63 and the inner wall of the transmission wheel A62. The outer wall of the recycling box 1 is fixedly connected to the mounting block 64. The middle part of the mounting block 64 is rotatably connected to the reciprocating screw 65. The top of the reciprocating screw 65 is fixedly connected to the transmission wheel B66. A transmission belt 613 is wrapped around the outer walls of the transmission wheel A62 and the transmission wheel B66. A movable opening 67 and a movable groove 68 are respectively opened on the inner and outer walls of the recycling box 1. The outer wall of the reciprocating screw 65 is threadedly connected to the connecting block 611. The outer wall of the connecting block 611 is fixedly connected to the movable plate 69. The middle part of the movable plate 69 is fixedly connected to the water outlet pipe 610. The movable plate 69 is slidably connected to the inside of the movable groove 68, and the length of the movable plate 69 is more than twice the length of the movable opening 67. A filter screen 612 is provided at one end of the outlet pipe 610 located inside the recovery box 1, and the movable opening 67 is connected to the movable groove 68.

[0029] During use, when the sewage inside the recycling box 1 is settled, the motor drives the rotating shaft 520 to rotate clockwise. Since the stirring shaft 41 is in forward and reverse rotation, no matter which direction the rotating shaft 520 rotates, it will not affect the stirring operation and the cleaning of the filter frame 51. When the rotating shaft 520 rotates clockwise, the ratchet 61 on its outer wall cooperates with the pawl 63 on the inner wall of the transmission wheel A62, and then the transmission wheel A62 will rotate accordingly, and then the transmission wheel B66 will be driven to rotate under the transmission action of the transmission belt 613, and then the transmission wheel B66 will drive the reciprocating screw 65 to rotate, and then the connecting block 611 threadedly connected to the outer wall of the reciprocating screw 65 will move accordingly, thereby driving the movable plate 69 to move on the inner wall of the movable groove 68. The movable opening 67 can be blocked at all times during the movement of the movable plate 69 to prevent sewage from flowing out. The filter screen 612 arranged at one end of the water outlet pipe 610 inside the recycling box 1 can prevent sediment from being discharged under the action of suction.

[0030] Example 3, please refer to Figure 1 - Figure 7Based on Example 1, a cleaning assembly 7 is mounted on the inner wall of the recycling bin 1. The cleaning assembly 7 includes a mounting shaft 71, which is rotatably connected to the inner wall of the recycling bin 1. A movable plate 72 is fixedly mounted on the outer wall of the mounting shaft 71. A cleaning block 73 is fixedly connected to the inner side of the movable plate 72. A connecting rod 74 is fixedly connected to the outer wall of the movable plate 72. The other end of the connecting rod 74 is fixedly connected to a vertical plate 75. A torsion spring 76 is fixedly connected to the inner wall of the recycling bin 1. The other end of the torsion spring 76 is fixedly connected to the movable plate 72. In the initial state, the height of the vertical plate 75 is consistent with the height of the lowest set of stirring plates 42.

[0031] When in use, when the stirring plate 42 rotates with the stirring shaft 41, the lowermost group of stirring plates 42 will contact the vertical plate 75 during the rotation, and then the stirring plate 42 will push the vertical plate 75, and the vertical plate 75 will drive the movable plate 72 to rotate along with the installation shaft 71 through the connecting rod 74, and then the cleaning block 73 on the inner side of the other end of the movable plate 72 will also rotate accordingly. During the rotation, the cleaning block 73 will contact the surface of the filter screen 612, and then the filter screen 612 can be cleaned. After the stirring plate 42 rotates a certain angle, the vertical plate 75 will be completely pushed to its bottom, and then the stirring plate 42 will leave the vertical plate 75. At this time, under the action of the torsion spring 76, the movable plate 72 will be driven to reset.

[0032] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
