DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application. The present application will be further described below with reference to the embodiments.

[0043] Please refer to Figures 1-5 In an embodiment of the present application, a scum removing device for sewage treatment includes a cleaning box 1, a controller 2 and a mounting table 8, the mounting table 8 and the controller 2 are arranged on the cleaning box 1, the mounting table 8 is provided with a supporting frame 6, the supporting frame 6 is formed with a clamping groove 7, and the scum removing device further includes:

[0044] An intermediate disc is movably arranged on the cleaning box 1, and a plurality of impurity removing channels 10 are arranged in the inner ring of the intermediate disc;

[0045] A power element is arranged on the cleaning box 1 and connected with the intermediate disc at the output end;

[0046] A drying module is arranged on the cleaning box 1 and used for drying the scum; and

[0047] A plurality of impurity removing systems are arranged around the intermediate disc and in communication with the impurity removing channels 10, and used for removing the scum in the sewage.

[0048] It should be particularly pointed out that the power element can be a stepping motor 9 or a servo motor, in the embodiment, the power element is preferably a stepping motor 9, the stepping motor 9 is arranged on the cleaning box 1 and connected with the intermediate disc at the output end, and the specific model of the stepping motor 9 can be selected according to the actual situation, which is not limited here.

[0049] In the embodiment, each of the impurity removing systems includes:

[0050] A mounting plate 11 is arranged on the intermediate disc, and the mounting plate 11 is formed with an impurity removing opening 16 in communication with the impurity removing channel 10;

[0051] A filter screen 13 is movably arranged in the through window formed in the mounting plate 11, and the two sides of the filter screen 13 are connected with the mounting plate 11 through elastic members;

[0052] A mounting frame 15 is arranged on the mounting plate 11;

[0053] A counterweight movably arranged on the mounting frame 15, wherein an arc-shaped skimmer 18 is arranged on the counterweight, and the skimmer 18 and the filter screen 13 are in clearance fit; and

[0054] A locking structure arranged on the mounting plate 11, for fixing the position of the counterweight.

[0055] Non-limitingly, the elastic member can be a spring 14, a spring piece or an elastic steel plate structure. In the embodiment, the elastic member is preferably a spring 14, which is connected between the filter screen 13 and the mounting plate 11. The specific type of the spring 14 can be selected as appropriate.

[0056] In actual application, the entire device is installed on the sewage pool through the support frame 6, and then the controller 2 controls the stepping motor 9 to be powered and rotated, driving the mounting plate 11 and the intermediate disc to rotate. When the mounting plate 11 passes through the sewage, the floating sludge on the surface of the sewage can be lifted by the skimmer 18 and falls onto the surface of the filter screen 13. In this process, the drying module is controlled to work, and hot air flow is input into the cleaning box 1, so that the impurities on the surface of the filter screen 13 can be dried. By arranging the locking structure, the locking structure can be controlled to work to release the counterweight when the mounting plate 11 and the filter screen 13 reach the expected position, so that the skimmer 18 moves along the mounting frame 15 under the action of the counterweight, thereby pushing the dust on the filter screen 13 to the impurity discharge channel 10 and discharging it, completing the work of fishing, drying and discharging the floating sludge on the surface of the sewage in the sewage pool.

[0057] Please refer to Figures 1-5 As another preferred embodiment of the present application, the locking structure comprises:

[0058] A limiting plate 20 arranged on the counterweight, wherein a through hole 25 is arranged on the limiting plate 20;

[0059] A drive wheel 12 movably arranged on the end of the mounting plate 11 away from the intermediate disc, wherein a torsion spring is arranged between the drive wheel 12 and the mounting plate 11;

[0060] A locking strip 19 movably arranged on the mounting plate 11 and coaxially connected with the drive wheel 12, wherein the through hole 25 is located on the movement path of the locking strip 19; and

[0061] A damping strip 5 arranged on the inner wall of the cleaning box 1, wherein the damping strip 5 is located on the movement path of the drive wheel 12.

[0062] In a specific case in the embodiment, the impurity removal system further comprises an adjusting module arranged between the mounting plate 11 and the mounting frame 15, for controlling the vibration of the filter screen 13 relative to the mounting plate 11.

[0063] In another specific case of this embodiment, the adjustment module includes:

[0064] The wave guide rail 17 is provided on the mounting frame 15;

[0065] An adjusting block is movably arranged on the counterweight block and the two are elastically connected, and the debris scooping plate 18 is arranged on the adjusting block; and

[0066] The resistance rod 22 is provided on the adjustment block, and both ends of the resistance rod 22 are in contact with the filter screen 13 and the wave guide rail 17 respectively.

[0067] It should be supplemented that a resistance reducing member is provided between the resistance rod 22 and the wave guide rail 17 to reduce the friction resistance between the wave guide rail 17 and the resistance rod 22 .

[0068] When the stepper motor 9 controls the intermediate disk and the mounting plate 11 to rotate to the moving angle, the driving wheel 12 and the damping strip 5 meet at this time. Under the action of the friction resistance between the driving wheel 12 and the damping strip 5, the driving wheel 12 is driven to rotate a certain angle and stops rotating under the restriction of the torsion spring. In this process, the locking strip 19 can be driven to rotate synchronously, so that the locking strip 19 is disengaged from the through hole 25. At this time, under the action of the gravity of the counterweight block, the debris scooping plate 18 can be driven to move synchronously, thereby moving along the filter screen 13, pushing the scum on the filter screen 13 to the debris discharge port 16 and finally discharged from the debris discharge channel 10. By setting a locking structure, the counterweight block and the debris scooping plate can be delayed. The time for the plate 18 to move along the filter 13 ensures that the impurities on the filter 13 are in full contact with the hot air flow output by the drying module. When the driving wheel 12 and the damping bar 5 are disengaged, the driving wheel 12 and the locking bar 19 are reset under the action of the torsion spring, thereby fixing the position of the counterweight block and the debris scooping plate 18. In the process of the movement of the counterweight block, the sliding cooperation between the interference rod 22 and the wave guide rail 17 can be used to drive the adjustment block and the interference rod 22 to reciprocate relative to the cooperation block, thereby driving the filter 13 to vibrate, on the one hand avoiding the clogging of the filter 13, and on the other hand improving the drying effect of impurities.

[0069] It should be noted that the resistance reduction component can be a ball or a roller 21. In this embodiment, the resistance reduction component is preferably a roller 21. The roller 21 is movably arranged on the resistance rod 22 and slides with the wave guide rail 17. As for the specific model parameters of the resistance reduction component, no specific limitation is made here.

[0070] See also Figure 1 As another preferred embodiment of the present application, the drying module includes:

[0071] The fan 3 is arranged on the cleaning box 1;

[0072] A heater 4 is provided on the cleaning box 1 and is connected to the output end of the fan 3; and

[0073] The drying seat 24 is arranged in the groove 23 formed in the cleaning box 1, and the drying seat 24 is connected to the heater 4.

[0074] In actual application, the controller 2 controls the operation of the fan 3 and the heater 4. The heater 4 can heat the airflow output by the fan 3 and input it into the drying seat 24. Finally, the hot airflow is ejected from the drying seat 24 and blows toward the scum attached to the filter 13 passing through, thereby completing the drying process of the scum. There is no need for the staff to use special drying equipment to reprocess the scum later.

[0075] How this application works:

[0076] The entire device is installed on the sewage pool through the support frame 6, and then the controller 2 controls the stepper motor 9 to be powered on and rotated, driving the mounting plate 11 and the intermediate disk to rotate. When the mounting plate 11 passes through the sewage, the scum floating on the surface of the sewage can be scooped up by the scooping plate 18 and dropped onto the surface of the filter 13. The controller 2 controls the operation of the fan 3 and the heater 4. The heater 4 can heat the airflow output by the fan 3 and input it into the drying seat 24. Finally, the hot airflow is ejected from the drying seat 24 and blown onto the scum attached to the filter 13 passing through, thereby completing the drying process of the scum, and there is no need for the staff to use special drying equipment to reprocess the scum later. When the stepper motor 9 controls the intermediate disk and the mounting plate 11 to rotate to the moving angle, the driving wheel 12 and the damping strip 5 meet at this time. Under the action of the friction resistance between the driving wheel 12 and the damping strip 5, the driving wheel 12 is driven to rotate a certain angle and stops rotating under the restriction of the torsion spring. In this process, the locking strip 19 can be driven to rotate synchronously, so that the locking strip 19 is disengaged from the through hole 25. At this time, under the action of the gravity of the counterweight block, the debris scooping plate 18 can be driven to move synchronously, thereby moving along the filter screen 13, pushing the scum on the filter screen 13 to the debris discharge port 16 and finally discharged from the debris discharge channel 10. By setting a locking structure, the counterweight block and the debris scooping plate can be delayed. The time for the plate 18 to move along the filter 13 ensures that the impurities on the filter 13 are in full contact with the hot air flow output by the drying module. When the driving wheel 12 and the damping bar 5 are disengaged, the driving wheel 12 and the locking bar 19 are reset under the action of the torsion spring, thereby fixing the position of the counterweight block and the debris scooping plate 18. In the process of the movement of the counterweight block, the sliding cooperation between the interference rod 22 and the wave guide rail 17 can be used to drive the adjustment block and the interference rod 22 to reciprocate relative to the cooperation block, thereby driving the filter 13 to vibrate, on the one hand avoiding the clogging of the filter 13, and on the other hand improving the drying effect of impurities.
