Detailed Description
As shown in the figure, this embodiment includes the sedimentation tank 3 installed on the base 17, the inner surface of the sedimentation tank 3 is a part of a cylinder, the two ends of the sedimentation tank are equipped with end plates, the two ends of the sedimentation tank are respectively provided with a first end plate corresponding to the water inlet end and a second end plate corresponding to the water outlet end, the end on the second end plate is provided with a groove serving as the water outlet 8, the first end plate is provided with a water inlet, or the water inlet pipe is directly arranged above the first end plate to enable the pipe orifice to directly enter the sedimentation tank 3, and the structure is more beneficial to the situation of large water quantity.
The radian between at least one side of the arc surface of the inner surface of the sedimentation tank 3 and the ground vertical line is smaller than 90 degrees, or both sides of the arc surface are smaller than 90 degrees, so that sludge can be discharged from one side or both sides of the arc surface conveniently. For facilitating the sludge discharge, the side surface of the sedimentation tank 3 can be further provided with a drainage plate 4, or a flexible sludge guide curtain is further designed on the side surface of the drainage plate 4 or the sedimentation tank 3 to adapt to the height of the sedimentation tank 3.
Through the first end plate and the second end plate, a main shaft 2 is arranged above the sedimentation tank 3, and the main shaft 2 is arranged on the axis of the sedimentation tank 3. The spindle 2 is connected to a motor mounted on the first end plate. A group of mud cleaning shovel 5 is fixed along the length direction of the main shaft 2, and the edge of the mud cleaning shovel 5 can be matched with the inner wall of the sedimentation tank 3, so that when the main shaft 2 rotates, the mud cleaning shovel 5 is shoveled out by mud in the sedimentation tank 3.
Since water still exists in the sludge, the present embodiment therefore designs the sludge shovel 5 to have the following structure: the mud cleaning shovel 5 comprises an outer frame 7 and a porous plate 6 fixed on the outer frame 7, wherein the porous plate 6 can be fixed on the outer frame 7 through a group of bolts, so that the porous plates 6 with different pore sizes can be replaced according to the constitution of mud in sewage.
Two corresponding rear support plates 16 are fixed on a base 17 near the second end plate, and two sides of the sedimentation tank 3 are connected with the two rear support plates 16 through shafts. A pair of front support plates 13 are arranged on a base 17 close to the first end plate, two sides of an L-shaped oil cylinder seat 15 are respectively connected with the two front support plates 13 through shafts, two oil cylinders 12 are arranged on the oil cylinder seat 15, and piston rods 11 of the two oil cylinders 12 are respectively connected with two sides of the sedimentation tank 3 through shafts. The cylinder seat 15 is provided with a positioning plate 14. In the above structure, the two cylinders 12 can be supplied with oil by the same oil pump, so that the cylinders can synchronously move, the front end of the sedimentation tank 3 is lifted, the sedimentation tank 3 is positioned at different inclination angles according to the condition of sludge in sewage, and the sedimentation time is prolonged or slowed down. The positioning plate 14 can play a supporting role in positioning the oil cylinder 12.
In addition, a sludge collecting tank 9 is arranged on one side or two sides of the sedimentation tank 3, so that the sludge can be conveniently collected. Because the radian of the mud outlet side of the sedimentation tank 3 is smaller than 90 degrees, the mud outlet effect can be fully ensured.
When the utility model is used, sewage enters the sedimentation tank 3 from the water inlet or from the upper part of the sedimentation tank 3, moves from top to bottom along the sedimentation tank 3, and in the process, sludge is precipitated and slowly deposited from bottom to top and flows out from the water outlet 8 on the second end plate. The utility model adopts overflow mode to discharge cleaner water, and the sludge is mainly deposited at the second end plate. After a period of deposition, the motor is started, and the main shaft 2 drives the mud cleaning shovel 5 to discharge mud from one side or the other side of the sedimentation tank 3.
A water receiving basin 10 may also be provided on the base 17 at the rear of the second end plate for connection with the equipment at the rear, as is practical.
