[0036] As Figures 1 to 8 shown, the water purification equipment for sewage treatment of the present application comprises a sedimentation tank 1 and a mounting frame 2 arranged in the sedimentation tank 1, the mounting frame 2 is rotatably installed in the sedimentation tank 1, a sewage pipe 11 is vertically arranged in the sedimentation tank 1, the sewage pipe 11 is coaxially arranged with the sedimentation tank 1, a receiving frame 12 is arranged at the upper end of the sewage pipe 11, the mounting frame 2 is rotatably matched with the receiving frame 12, a driving part one 13 is arranged on the receiving frame 12, the driving part one 13 is arranged as a motor, the output end of the driving part one 13 is connected with the mounting frame 2 to drive the mounting frame 2 to rotate. The mounting frame 2 is provided with a filtering frame 3, a driving assembly 4, an extruding assembly 5 and a collecting assembly 6, the driving part one 13 drives the mounting frame 2 to rotate, at the same time, the driving assembly 4 cooperates with the filtering frame 3 to clean the impurities in the sedimentation tank 1, then the extruding assembly 5 processes the collected impurities to discharge the water in the impurities, and finally the collecting assembly 6 collects the impurities.

[0037] Referring to Figure 1 , Figure 2 , Figure 7Support wheels 21 are arranged at the bottom of the mounting frame 2, the support wheels 21 are rotatably arranged on the mounting frame 2, and the support wheels 21 are arranged at both ends of the support frame, support portions 14 are arranged on the inner side of the sedimentation tank 1 in a circumferential direction, and the support portions 14 are coaxially arranged with the rotating shaft of the mounting frame 2. The support wheels 21 are located between the mounting frame 2 and the support portions 14, and the support wheels 21 are placed on the support portions 14. When the mounting frame 2 rotates, the support wheels 21 rotate synchronously, and at the same time, the support wheels 21 support the mounting frame 2 to improve the stability of the mounting frame 2 during rotation.

[0038] Referring to Figure 2 , Figure 3 , Figure 4 The filter frame 3 is slidably arranged on the mounting frame 2, and the filter frame 3 is arranged on the mounting frame 2. An intercepting portion 7 is arranged at the bottom of the filter frame 3, a plurality of through holes are arranged on the intercepting portion 7, that is, the intercepting portion 7 also has a filtering function. The intercepting portion 7 is arranged perpendicular to the filter frame 3, the filter frame 3 rotates with the mounting frame 2, and the intercepting portion 7 is arranged on the side of the filter frame 3 close to the rotating direction.

The collecting assembly 6 is located on one side of the extrusion assembly 5.

[0039] The driving member 13 drives the mounting frame 2 to rotate, and the mounting frame 2 drives the filter frame 3 to rotate synchronously. The filter frame 3 filters the impurities floating in the water while rotating, and when the filter frame 3 moves upwards, the intercepting portion 7 at the bottom of the filter frame 3 intercepts the impurities to prevent the impurities filtered by the filter frame 3 from falling off the filter frame 3. At the same time, the up-and-down movement of the intercepting portion 7 can increase the stirring effect of the sewage, so that the medicine water and the sewage are mixed more fully. In addition, since the intercepting portion 7 is arranged horizontally, when the intercepting portion 7 moves up and down, the impurities at the bottom of the sedimentation tank 1 will be disturbed, so that the impurities at the bottom of the sedimentation tank 1 float in the water. When the sewage is treated, the intercepting portion 7 and the filter frame 3 continuously move in a circular motion in the sedimentation tank 1. After the intercepting portion 7 disturbs the impurities at the bottom of the sedimentation tank 1 to make them float, the filter frame 3 and the intercepting portion 7 can collect and treat the impurities.

[0040] Referring to Figure 4 , Figure 5 The extrusion assembly 5 includes an elastic expansion plate 51 and an extrusion plate 52, wherein the extrusion plate 52 is located directly above the intercepting portion 7, and the extrusion plate 52 is arranged parallel to the intercepting portion 7. The elastic expansion plate 51 is a plate-shaped structure that can expand and contract. Specifically, the elastic expansion plate 51 includes an outer plate, an inner plate, and a spring. The outer plate is slidably arranged outside the inner plate, and the spring is arranged between the two plates and connected to the inner plate and the outer plate at both ends, so that the elastic expansion plate 51 can expand and contract and has elasticity.

[0041] The driving assembly 4 drives the filter frame 3 to move up and down, and after driving the intercepting part 7 to move to the outside of the water surface, the intercepting part 7 is continuously driven to move, so that the intercepting part 7 is close to the extrusion plate 52, and the impurities on the intercepting part 7 are extruded by cooperating with the extrusion plate 52 to remove the water in the impurities, so as to avoid secondary treatment of the impurities, and facilitate collection of the impurities.

[0042] In addition, the side of the extrusion plate 52 close to the filter frame 3 is arranged to slide and abut against the side of the filter frame 3, and when the filter frame 3 moves upward and passes through the extrusion plate 52, the impurities on the filter frame 3 can be scraped to the intercepting part 7 by the extrusion plate 52, so as to extrude the impurities sufficiently.

[0043] Referring to Figure 4 , Figure 5 The collecting assembly 6 comprises a pushing piece 61, a scraper 62 and a collecting frame 63, the collecting frame 63 is provided with an opening, the pushing piece 61 is arranged as a pneumatic cylinder, the upper end of the elastic telescopic plate 51 is slidably connected with the bottom of the mounting frame 2, the output end of the pushing piece 61 is connected with the elastic telescopic plate 51, that is, the piston rod of the pneumatic cylinder is connected with the elastic telescopic plate 51, so as to drive the elastic telescopic plate 51 to move left and right along the horizontal direction, and the opening of the collecting frame 63 is arranged upward, and the collecting frame 63 is arranged in a spaced manner with the filter frame 3.

[0044] After the intercepting part 7 moves close to the extrusion plate 52 to extrude the impurities, the lower end of the vertical part 622 abuts against the upper surface of the intercepting part 7, and at this time, the upper surface of the intercepting part 7 is flush with the opening of the collecting frame 63, then the pushing piece 61 drives the elastic telescopic plate 51 to move close to the collecting frame 63, and the elastic telescopic rod drives the extrusion plate 52 and the scraper 62 to move synchronously, that is, the extrusion plate 52 and the vertical part 622 both move horizontally relative to the intercepting part 7, and the vertical part 622 pushes the impurities on the intercepting part 7 to the upper side of the opening of the collecting frame 63 while moving, so that when the extrusion plate 52 moves to the upper side of the collecting frame 63, the impurities can be transferred to the collecting frame 63, and the collection of the impurities is completed.

[0045] Referring to Figure 4 , Figure 5 The extrusion plate 52 is provided with a sliding rod 521 above, the sliding rod 521 is arranged in the vertical direction, the horizontal part 621 is connected with the extrusion plate 52 through the sliding rod 521, and the horizontal part 621 is sleeved on the outside of the sliding rod 521, and the horizontal part 621 is slidably connected with the sliding rod 521 in the up-down direction. A spring 522 is arranged between the horizontal part 621 and the extrusion plate 52 to connect the two, and the spring 522 is arranged as a spring.

[0046] Initially, the horizontal part 621 is close to the pressing plate 52, and the lower end of the vertical part 622 is below the pressing plate 52. After the intercepting part 7 is close to the pressing plate 52, the intercepting part 7 first abuts against the lower end of the vertical part 622, and then the intercepting part 7 continues to move to drive the impurities to cooperate with the pressing plate 52 to press the impurities. The lower end of the vertical part 622 and the intercepting part 7 are always in abutting state during the pressing. The elastic member 522 is arranged to elastically connect the horizontal part 621 and the pressing plate 52, so as to avoid the phenomenon that the vertical part 622 interferes with the movement of the intercepting part 7.

[0047] With reference to Figure 4 , Figure 5 The plurality of slide rods 521 are uniformly distributed on the pressing plate 52, and the plurality of slide rods 521 cooperate with the horizontal part 621 to improve the stability of the horizontal part 621 during movement.

One end of the collecting frame 63 close to the blowdown pipe 11 extends above the intermediate frame 8. The blowdown opening 631 is arranged at the bottom of the collecting frame 63 and located above the intermediate frame 8. The spiral conveying piece 632 is rotatably arranged in the collecting frame 63. The axis of the spiral conveying piece 632 is arranged in the length direction of the collecting frame 63. In addition, the motor (not shown in the figure) is arranged on the collecting frame 63, and the output end of the motor is connected with the rotating shaft of the spiral conveying piece 632.

[0049] After the impurities enter the collecting frame 63, the spiral conveying piece 632 rotates to drive the impurities in the collecting frame 63 to enter the intermediate frame 8, and then enter the blowdown pipe 11 through the intermediate frame 8 to collect the impurities through the blowdown pipe 11.

[0050] With reference to Figure 2 , Figure 3The driving assembly 4 includes: a second driving member 41, a driving screw 42, and a driving sleeve 43. The second driving member 41 is configured as a motor. The driving screw 42 is arranged in the vertical direction, that is, the driving screw 42 is arranged along the moving direction of the filter frame 3. The driving sleeve 43 is installed on the filter frame 3. The driving sleeve 43 is sleeved on the outside of the driving screw 42. The driving sleeve 43 is threadedly connected to the driving screw 42. The output end of the second driving member 41 is coaxially connected to the driving screw 42.

[0051] The second driving member 41 drives the driving screw 42 to rotate back and forth, and the driving rotation drives the driving sleeve 1 43 to move, and the movement of the driving sleeve 1 43 drives the filter frame 3 to move, and the filter screen moves up and down along with the rotation direction of the driving screw 42, thereby realizing the up and down movement of the filter frame 3.

[0052] To improve the sewage treatment effect, a medicine spraying pipe 9 is installed on the mounting frame 2. The medicine spraying pipe 9 includes multiple vertically arranged medicine spraying parts 91, and each medicine spraying part 91 is provided with multiple medicine spraying holes 92 arranged in an upper and lower arrangement. When the mounting frame 2 rotates, the medicine spraying pipe 9 rotates synchronously, and the rotation of the medicine spraying pipe 9 drives the medicine spraying parts 91 to rotate synchronously. At the same time, the medicine is sprayed into the sewage through the medicine spraying holes 92, so that the medicine and the sewage are fully in contact, thereby improving the sewage treatment effect.

[0053] Reference Figure 2 、 Figure 3 Two sets of drive screws 42 are provided, one on each side of the mounting frame 2. A second drive sleeve 93 is provided on the medicine dispensing tube 9. The second drive sleeve 93 is sleeved onto the drive screws 42 and threadedly engaged with the drive screws 42. Specifically, the two sets of drive screws 42 engage with the first drive sleeve 43 and the second drive sleeve 93, respectively. A second drive element 41 is provided between the two sets of drive screws 42. A transmission belt 411 is provided at the output end of the second drive element 41. The transmission belt 411 is sleeved around the exterior of both sets of drive screws 42. Specifically, the second drive screw 42 drives both sets of drive screws 42 to rotate simultaneously via the transmission belt 411, and the two sets of drive screws 42 rotate in opposite directions at the same time. As the filter frame 3 moves up and down, the medicine dispensing tube 9 also moves up and down simultaneously, evenly dispensing the liquid medicine into the sewage, ensuring full contact between the liquid medicine and the sewage.

[0054] The driving member two 41 drives the filter frame 3 to move up and down, and drives the interception part 7 to move up and down, and the frequency of the upward movement of the interception part 7 to the outside of the sewage can be adjusted according to the collection of impurities on the interception part 7. In the embodiment, when the driving member two 41 drives the driving screw 42 to rotate forward, the filter frame 3 is driven to move downward, and when the driving screw 42 is reversed, the filter frame 3 is driven to move upward. During normal operation, the driving member two 41 drives the driving screw 42 to rotate forward and reverse the same number of times, that is, the distance of the downward movement of the filter frame 3 is the same as the distance of the upward movement, and at this time the interception part 7 is always in the sewage. When it is necessary to clean the impurities on the interception part 7, the number of times of reversing the driving screw 42 is adjusted so that the distance of the upward movement of the interception part 7 is greater than the distance of the downward movement, so that the interception part 7 moves to the outside of the sewage to cooperate with the extrusion plate 52 to extrude the impurities. Specifically, in the embodiment, the filter frame 3 is arranged to be cleaned once for the interception part 7 every time the mounting frame 2 rotates one revolution in the sedimentation tank 1, that is, after the filter frame 3 rotates one revolution, the number of times of reversing the driving screw 42 driven by the driving member two 41 is increased, so that the interception part 7 moves to the outside of the sewage. At this time, the impurities on the interception part 7 are cleaned. In addition, in the initial stage of sewage treatment, the impurities on the interception part 7 can be cleaned once every half revolution. Specifically, the cleaning frequency of the interception part 7 can be adjusted adaptively according to the situation of the impurities in the sewage.

[0055] In addition, in order to facilitate the monitoring of the progress of sewage treatment, a torque sensor can be arranged on the rotating shaft of the mounting frame 2 to monitor the torque of the rotating shaft of the mounting frame 2. The torque of the rotating shaft of the mounting frame 2 corresponds to the amount of impurities in the sewage, that is, when there are more impurities, the impurities on the filter frame 3 are more, and the resistance they receive when rotating with the mounting frame 2 is greater. At this time, the rotating shaft of the mounting frame 2 receives a larger torque. As the impurities gradually decrease, the resistance of the filter frame 3 when rotating also decreases. The cleaning of the impurities can be monitored according to the data detected by the torque sensor to timely grasp the progress of the sewage treatment.

[0056] Referring to Figure 2 , Figure 3 , the pesticide pipes 9 and the filter frames 3 are provided in two groups, and the pesticide pipes 9 and the filter frames 3 in each group are arranged on the two sides of the mounting frame 2, and the filter frames 3 in the two groups are symmetrically arranged around the center of rotation of the mounting frame 2. That is, the pesticide pipes 9 in one group and the filter frames 3 in the other group are located on the same side of the mounting frame 2, and the interception part 7 is arranged on the side of the filter frame 3 close to the pesticide pipe 9. When the mounting frame 2 rotates, it drives the two groups of pesticide pipes 9 and filter frames 3 to rotate synchronously, so that the reaction of the medicine water and the sewage is more sufficient, and at the same time the collection efficiency of the filter frame 3 on the impurities is improved.
