Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in figures 1 to 4, the power plant desulfurization wastewater clarification device comprises a settling tank with a circular cross section, wherein the settling tank is vertically arranged during use, so that sludge sedimentation and accumulation are facilitated. The settling tank comprises a tank body 1 and a cover body 2 arranged at the top of the tank body 1, and the tank body and the cover body are connected through bolts. The drain 1.3 of the bottom of the tank body 1 is provided with a butterfly valve 3, and the drain 1.3 is connected with the tank body 1 through a conical part, so that the sewage discharge is facilitated. The liquid inlet 1.2 of the tank body 1 is higher than the liquid outlet 1.1. A piston 5 capable of moving along the central axis of the settling tank is arranged in the settling tank, and the piston 5 and the inner wall of the tank body 1 form dynamic seal. The piston 5 is provided with a one-way valve 6 and a filter screen plate 7 positioned below the one-way valve. The check valve 6 is switched to the on state when the pressure applied to the valve element from below exceeds the self-opening pressure. The cover body 2 is provided with a lifting device 4, and the lifting device 4 is connected with a piston 5.
In an alternative embodiment, as shown in fig. 3 and 4, the bottom surface of the piston 5 is provided with a mounting groove 5.2, and the top surface of the mounting groove 5.2 is provided with a mounting hole 5.4 penetrating the top surface of the piston 5. The check valve 6 is arranged at the mounting hole 5.4, and the filter screen plate 7 is arranged in the mounting groove 5.2 through a press ring I8. The pressing ring I8 is fixed to the bottom surface of the piston 5 by screws. A certain space is formed between the filter screen plate 7 and the top of the mounting groove 5.2, so that the filtered clear liquid can conveniently enter the one-way valve 6.
In an alternative embodiment, the piston 5 is provided with a receiving portion 5.3 corresponding to the communication mounting hole 5.4, and the one-way valve 6 is arranged in the receiving portion 5.3. The check valve 6 is fixed in the housing portion 5.3, and may be fixed by a screw connection or a tight fit.
In an alternative embodiment, as shown in fig. 3 and 4, the piston 5 is further provided with an annular rubber plate 10, and the outer diameter of the piston 5 is smaller than the inner diameter of the tank 1; the outer edge of the annular rubber sheet 10 is brought into sliding contact with the inner wall of the tank 1. It should be noted that the outer diameter of the annular rubber plate 10 should be slightly larger than the inner diameter of the tank 1, so that the annular rubber plate 10 can be tightly attached to the inner wall of the tank 1 by the elasticity of the annular rubber plate. More closely, the outer disc of piston 5 is provided with the seal groove, is provided with the sealing washer 9 that can form dynamic seal with the inner wall of jar body 1 in the seal groove. The packing 9 can prevent sludge from contacting the annular rubber plate 10, thereby causing abrasion of the annular rubber plate 10.
In an alternative embodiment, the annular rubber plate 10 is fixed to the top surface of the piston 5 by a pressing ring II 11. The pressing ring II11 is fixed to the top surface of the piston 5 by screws.
In an alternative embodiment, a piston rod 5.1 is arranged in the center of the top surface of the piston 5, and the piston rod 5.1 is connected with the movable end of the lifting device 4. The piston rod 5.1 is connected with the movable end of the lifting device 4 through a bolt.
In an alternative embodiment, the number of non-return valves 6 is 8 and is evenly distributed in the circumferential direction. The collection of the clear liquid can be accelerated by the plurality of check valves 6, thereby increasing the processing speed.
In an alternative embodiment, the lifting device 4 is a hydraulic cylinder.
The piston 5 moves to a height higher than the liquid inlet 1.2, and at the moment, the waste water enters the tank body 1 from the liquid inlet 1.2. The sludge gradually settles with the passage of time. When the sedimentation is completed, the piston 5 is lowered to press the sludge therebelow, forcing the liquid in the sludge to be separated from the sludge by the filtering action of the screen plate 7, as shown in fig. 5. As the piston 5 descends, the valve body of the check valve 6 is moved by the liquid, and the check valve 6 is opened. In this way, the clear liquid enters the space above the piston 5 and is collected. After the sludge and the clear liquid are separated to a certain degree, the butterfly valve 3 is opened, the piston 5 continues to descend at the moment, the sludge is discharged from the sewage outlet 1.3, and finally the butterfly valve 3 is closed. As shown in fig. 6, after the sewage is discharged, the lifting device 4 drives the piston 5 to move upward, at this time, the check valve 6 is closed because the pressure applied by the lower clear liquid is no longer applied, the clear liquid above the piston 5 moves upward along with the upward movement of the piston 5, when the liquid level exceeds the liquid outlet 1.1, the clear liquid is discharged from the liquid outlet 1.1, and the piston 5 continuously moves upward until the clear liquid is completely discharged. And after the piston 5 returns to the original position, introducing the wastewater into the tank body 1 again for precipitation treatment.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
