Wherein, damper can include support column, damping spring and shock pad. The support column sets up in the below of sludge pump 2, and damping spring sets up between support column and shock pad. In the use of sludge pump 2, the support column plays the effect that supports sludge pump 2, and damping spring and shock pad play absorbing effect. Alternatively, the first and second electrodes may be,
the shock absorption mechanism comprises a supporting plate 34, a shock absorption component and a rubber pad 38; the shock absorbing assembly is disposed on the support plate 34; the rubber pad 38 is arranged between the sludge pump 2 and the damping component; the shock-absorbing assembly comprises an upper shock-absorbing pad 35, a spring shock absorber 36 and a lower shock-absorbing pad 37; the spring damper 36 has two ends connected to the upper cushion 35 and the lower cushion 37, respectively, the lower cushion 37 is abutted to the support plate 34, and the upper cushion 35 is abutted to the rubber pad 38.

In this embodiment, in the use, because sludge pump 2 produces great vibrations when taking out mud, cause the influence to mud pipeline 1 and sludge sedimentation tank 3, probably produce spare part not hard up or the junction connects unstable condition. The damping mechanism can play a damping role, so that the structure is prevented from being damaged.
On the basis of the above embodiment, further, an embodiment of the present invention further provides a sludge collection method based on the above sludge collection device, where the sludge collection method includes the following steps:
introducing sludge in the integrated sewage treatment equipment into a sludge sedimentation tank 3;
settling the sludge in a sludge settling tank 3;
discharging liquid at the upper part of the sludge sedimentation tank 3, and discharging sludge at the bottom of the sludge sedimentation tank 3 to the solid-liquid separation mechanism 6;
carrying out solid-liquid separation on the sludge at the bottom of the sludge sedimentation tank 3 in a solid-liquid separation mechanism 6;
the solids in the bowl 13 are collected.
In this embodiment, in the use, open first valve 7, sludge pump 2 takes out the mud in the integration sewage treatment device, enters into mud sedimentation tank 3 along mud pipeline 1 and deposits. Because the solid is lighter than the liquid, the sludge sedimentation tank 3 is gradually layered, the turbidity meter 9 can detect the turbidity data of the liquid on the upper part of the sludge sedimentation tank 3 and transmit the turbidity data to the controller, and when the turbidity data is smaller than a preset value, the controller controls the first electric control valve 10 to be opened; the upper liquid is discharged from the sludge settling tank 3 from the first drainage pipe. At this time, the second valve 8 is opened, and the sludge at the bottom of the sludge settling tank 3 enters the drum 13 along the first sludge discharge pipe 4 and the feed pipe 5. The motor 11 is rotated to drive the rotating shaft 12 and the rotating drum 13 to rotate, sludge is thrown outwards onto the inner wall of the rotating drum 13 under the action of centrifugal force, when the sludge flows upwards along the inner wall of the rotating drum 13, liquid flows upwards due to the fact that the friction force between the solid and the inner wall of the rotating drum 13 is larger than the upward impulsive force of the liquid, the liquid is finally separated through the opening 16 at the top of the rotating drum, the thrown liquid is thrown onto the guide plate 14 and flows to the liquid collecting tank 15 along the guide plate 14, and the solid is reserved inside the rotating drum 13. The effect of guide plate 14 can prevent that liquid from getting rid of and flying, makes things convenient for liquid to concentrate and collects to liquid collecting vat 15 in.
As can be seen from the above, with the above-described sludge collection method, the sludge in the integrated sewage treatment apparatus undergoes the sedimentation in the sludge sedimentation tank 3 and the solid-liquid separation in the solid-liquid separation mechanism 6, and finally the solids are retained in the drum 13, and the liquid is discharged from the first drain pipe and collected in the liquid collection tank 15. Therefore, solid-liquid separation can be realized, the subsequent recycling of solid and liquid is convenient, and the environment is protected.
