[0028] The present invention has the following beneficial effects:

[0029] 1. In the present invention, the collecting net frame and the cleaning roller are driven to move up and down reciprocatingly on the intercepting and filtering side of the filter grid by the lifting drive assembly. At the same time, the cleaning roller can rotate synchronously during the lifting and moving process to clean the floating objects and suspended objects intercepted and attached to the side of the filter grid and transport them to the collecting net frame, so as to prevent the floating objects and suspended objects from clogging the filter grid, so that the filter grid maintains a good filtering effect, and the floating objects and suspended objects cleaned are stored in the collecting net frame, which can prevent the floating objects and suspended objects from re-dispersing in the grid pool, thereby ensuring the normal and stable operation of the grid pool.

[0030] When the collecting net frame moves upward to the sewage trough position, the push plate moves to one side of the sewage outlet, and at the same time, the rotation drive assembly drives the push plate to rotate and push it into the sewage outlet to push and discharge the floating objects and suspended objects, thereby realizing automatic sewage discharge, making the sewage discharge process of the collecting net frame more convenient and quick. At this time, the push plate is folded and arranged in the collecting net frame, so that when the push plate is subsequently reset and moved in the collecting net frame, the floating objects and suspended objects collected therein will not be pushed and moved in the reverse direction, ensuring that the floating objects and suspended objects in the collecting net frame are unidirectionally transported therein and finally discharged from the sewage outlet. When the push plate moves to the right end of the collecting net frame, the rotation drive assembly drives the push plate to rotate and unfold in the collecting net frame to prepare for the next round of pushing and sewage discharge, which is convenient for the reciprocating sewage discharge of the collecting net frame.

[0046] Specifically, when the wastewater treatment equipment is working, the wastewater is first transported to the grid pool 1, and the filter grid 11 in the grid pool 1 intercepts and filters the larger floating objects and suspended objects in the wastewater. After that, the wastewater is transported to the subsequent wastewater multi-stage treatment mechanism, and then the wastewater is subjected to multi-stage purification treatment; at the same time, the collection net frame 61 and the cleaning roller 62 are driven by the lifting drive component to reciprocate and lift on the intercepting and filtering side of the filter grid 11, and the cleaning roller 62 can rotate synchronously during the lifting and moving process to clean and transport the floating objects and suspended objects intercepted and attached to the side of the filter grid 11 to the collection net frame 61; the translation drive component can drive the push plate 75 to move in the collection net frame 61 toward the sewage outlet 79 when the collection net frame 61 is upward, thereby The floating objects and suspended objects collected by the collecting net frame 61 are pushed toward the sewage outlet 79. When the collecting net frame 61 ascends to the sewage trough position, the push plate 75 moves to the side of the sewage outlet 79, and the rotary drive assembly drives the push plate 75 to rotate and push into the sewage outlet 79 to push and discharge the floating objects and suspended objects.

The transmission rack 713 is fixedly mounted on the inner side wall of the grid pool 1 and is meshed and transmission-connected with the transmission gear 714.

[0052] A driving gear 69 is fixedly mounted on one end of the translation driving screw rod 71 , and a driven gear 68 meshingly connected to the driving gear 69 is fixedly mounted on one end of the cleaning roller 62 .

[0053] When cleaning and discharging sewage, the motor 63 drives the reciprocating screw 64 connected to it to rotate, and at the same time, the reciprocating screw 64 drives another reciprocating screw 64 to rotate synchronously through the transmission of the synchronous wheel 66 and the synchronous belt 65. When the two reciprocating screws 64 rotate, the lifting seat 67 is driven to reciprocate and lift through the threaded transmission, thereby driving the collection net frame 61 to lift and move; wherein, when the collection net frame 61 moves upward, it drives the transmission gear 714 to move upward synchronously along the transmission rack 713. At this time, the transmission gear 714 rotates under the meshing drive of the transmission rack 713, thereby driving the translation drive screw 71 to rotate. At this time, the translation drive screw 71 is driven by the meshing transmission of the driving gear 69 and the driven gear 68 The cleaning roller 62 rotates so that the cleaning roller 62 cleans the filter grille 11 when it moves upward, and transports the cleaned impurities to the collecting frame 61 through the rotating centrifugal force, and at the same time, the translation driving screw rod 71 drives the push plate 75 to move toward the sewage outlet 79 through the threaded transmission, so that the push plate 75 transports the impurities collected in the collecting frame 61 toward the sewage outlet 79; and when the collecting frame 61 moves downward, the translation driving screw rod 71 and the cleaning roller 62 rotate in the opposite direction driven by the gear rack, and the cleaning roller 62 continues to clean the filter grille 11 during the reverse rotation, and the translation driving screw rod 71 drives the push plate 75 to translate and reset in the reverse direction in the collecting frame 61 when rotating in the reverse direction.

[0054] Embodiment 3

[0055] See also Figure 3-Figure 8 As shown, the difference between this embodiment and the above-mentioned embodiment is that the rotation drive assembly includes a bracket 74, the bracket 74 is fixedly mounted on the bottom end of the translation slide 72, a positioning seat 76 is fixedly mounted on the top surface of the bracket 74, a rotating shaft 720 is rotatably mounted inside the positioning seat 76, a push plate 75 is fixedly mounted on the bottom end of the rotating shaft 720, and a lifting gear 715 is fixedly mounted on the top end of the rotating shaft 720; a lifting slide groove is arranged inside the positioning seat 76, a shaft sleeve 719 is slidably mounted in the lifting slide groove, the shaft sleeve 719 is rotatably mounted on the outer ring of the rotating shaft 720, a spline 718 is arranged on one side of the shaft sleeve 719, a spline groove 716 slidably engaged with the spline 718 is arranged inside the positioning seat 76, a lifting guide groove 717 is arranged on one side of the spline groove 716, and a guide shaft 77 extending outward along the lifting guide groove 717 is fixedly mounted on the outer side surface of the spline 718;

[0056] The rotary drive assembly also includes a push drive rack 78, an upward guide frame 710, a reset drive rack 711 and a downward guide frame 712. The push drive rack 78 and the upward guide frame 710 are fixedly mounted on the inner wall of the left end of the collecting net frame 61. The push drive rack 78 is located on the lower moving track of the lifting gear 715. One side of the upward guide frame 710 is provided with an upward inclined guide groove that can push the guide shaft 77 upward. The reset drive rack 711 is located on the upper moving track of the lifting gear 715. On the trace, a downward inclined guide groove capable of pushing and moving the guide shaft 77 downward is provided on one side of the downward guide frame 712; two pin holes 721 distributed up and down are provided on one side of the shaft sleeve 719; a telescopic sliding hole 722 corresponding to the pin hole 721 is provided inside the positioning seat 76; a pin shaft 724 is slidably installed inside the telescopic sliding hole 722; a pressure spring 723 is abutted against the inner side end of the pin shaft 724; a cylindrical head capable of being slidably inserted into the inner side of the pin hole 721 is provided on the outer side end of the pin shaft 724;

[0057] The pin 724 is initially inserted into the pin hole 721 at the upper end of the sleeve 719, so that the sleeve 719 is limited in the vertical direction by the pin connection between the pin 724 and the pin hole 721, thereby improving the stability of the sleeve 719, the rotating shaft 720 and the push plate 75 in the vertical direction. At the same time, the sleeve 719 limits the circumferential direction of the rotating shaft 720 through the friction resistance of the contact surface between the sleeve 719 and the rotating shaft 720, so as to further improve the installation stability of the rotating shaft 720 and the push plate 75, and prevent the push plate 75 from rotating and shaking by itself.

[0058] When the collecting net frame 61 moves upward and drives the translation driving screw 71 to rotate, the translation driving screw 71 drives the translation slide 72 to move leftward along the optical axis guide rail 73 through the thread transmission, thereby driving the push plate 75 to move leftward in the collecting net frame 61 through the support 74, the positioning seat 76 and the rotating shaft 720, so that the push plate 75 pushes the impurities in the collecting net frame 61 to the left for transportation. When the collecting net frame 61 moves upward to the drain tank position and the lifting gear 715 at the top of the rotating shaft 720 moves to the push drive rack 78 position, the lifting gear 715 moves to the push drive rack 78 position. When the lifting gear 715 is in the state of being engaged and driven by the push material driving rack 78, it rotates counterclockwise, thereby driving the rotating shaft 720 to rotate counterclockwise. At this time, the rotating shaft 720 drives the push plate 75 to rotate counterclockwise, so that one end of the push plate 75 gradually rotates and moves toward the sewage outlet 79, and the impurities in the collection net frame 61 are pushed out from the sewage outlet 79 and the sewage trough, until the lifting gear 715 moves past the push material driving rack 78. At this time, the lifting gear 715, the rotating shaft 720 and the push plate 75 rotate 90 degrees. The push plate 75 is parallel to the side wall of the collecting net frame 61, and then the guide shaft 77 moves to the position of the upward guide frame 710. The guide shaft 77 moves upward under the guidance of the upward inclined guide groove in the upward guide frame 710, thereby driving the shaft sleeve 719, the rotating shaft 720, the lifting gear 715 and the push plate 75 to move upward, so that the bottom surface of the push plate 75 is separated from the bottom surface of the collecting net frame 61, and the lifting gear 715 moves to the upward track and staggered with the push drive rack 78, and the pin shaft 724 is on the shaft. When the sleeve 719 moves upward, it is abutted and retracted under the guidance of the cylindrical head until the sleeve 719 reaches the top. The pin 724 is inserted into the pin hole 721 at the lower end of the sleeve 719 under the elastic force of the pressure spring 723, so that the sleeve 719 is continuously limited in the vertical direction through the cooperation between the pin 724 and the pin hole 721, thereby improving the stability of the sleeve 719, the rotating shaft 720 and the push plate 75 in the vertical direction, and preventing the sleeve 719, the rotating shaft 720 and the push plate 75 from falling downward by themselves.

[0059] Afterwards, the collecting net frame 61 moves downward and drives the translation driving screw rod 71 to rotate in the opposite direction. At this time, the translation driving screw rod 71 drives the translation slide 72 to move to the right and reset along the optical axis guide rail 73 through thread transmission, thereby driving the push plate 75 to move to the right and reset in the collecting net frame 61 through the cooperation of the bracket 74, the positioning seat 76 and the rotating shaft 720. Since the lifting gear 715 is staggered with the pushing drive rack 78, the lifting gear 715 will not drive the push plate 75 to rotate and reset when it moves to the right and resets through the pushing drive rack 78, so that the push plate 75 moves and resets in the collecting net frame 61 in a folded and suspended state, thereby preventing the push plate 75 from pushing and transporting impurities in the collecting net frame 61 in the opposite direction when resetting; and when the push plate 75 moves to the right end of the collecting net frame 61, the lifting gear 715 moves to the reset drive rack 711. At this time, the lifting gear 715 rotates in the opposite direction under the drive of the reset driving rack 711, thereby driving the rotating shaft 720 and the push plate 75 to rotate in the opposite direction, so that the push plate 75 rotates and resets, and is unfolded again and arranged inside the collecting net frame 61. Then the guide shaft 77 moves to the position of the downward guide frame 712. The guide shaft 77 moves downward and resets under the guidance of the downward inclined guide groove in the downward guide frame 712, thereby driving the sleeve 719, the rotating shaft 720, the lifting gear 715 and the push plate 75 to move downward and reset, so that the bottom surface of the push plate 75 is re-contacted with the bottom surface of the collecting net frame 61, completing the entire reset process. At the same time, the pin shaft 724 is again inserted into the pin hole 721 at the upper end of the sleeve 719 to limit the sleeve 719, the rotating shaft 720 and the push plate 75, thereby improving the stability of the push plate 75.

[0060] Embodiment 4

[0062] The wastewater generated by the medicinal material water treatment is transported to the grid pool 1, and the filter grid 11 in the grid pool 1 intercepts and filters the larger floating objects and suspended objects in the wastewater. After that, the wastewater is transported to the subsequent wastewater multi-stage treatment mechanism, and then the wastewater is subjected to multi-stage purification treatment;

[0063] At the same time, the collection net frame 61 and the cleaning roller 62 are driven by the lifting drive assembly to reciprocate and lift on the interception and filtering side of the filter grid 11. The cleaning roller 62 can rotate synchronously during the lifting and moving process to clean and transport the floating and suspended matter intercepted and attached to the side of the filter grid 11 to the collection net frame 61;

[0064] The translation drive assembly can drive the push plate 75 to move in the collection net frame 61 toward the sewage outlet 79 when the collection net frame 61 moves upward, so as to push the floating objects and suspended objects collected by the collection net frame 61 toward the sewage outlet 79. When the collection net frame 61 moves upward to the sewage trough position, the push plate 75 moves to the side of the sewage outlet 79, and at the same time, the rotation drive assembly drives the push plate 75 to rotate and push it into the sewage outlet 79, so as to push and discharge the floating objects and suspended objects, and at this time, the push plate 75 is folded and arranged in the collection net frame 61.

[0065] Afterwards, the translation drive assembly drives the push plate 75 to move and reset in the direction away from the sewage outlet 79 when the collecting net frame 61 descends, and when the collecting net frame 61 descends to the lower end position of the filter grid 11, the push plate 75 moves to the right end of the collecting net frame 61, and at the same time, the rotation drive assembly drives the push plate 75 to rotate and unfold in the collecting net frame 61, preparing for the next round of pushing materials and discharging sewage.
