Abstract
Description
Technical Field
[0001] The utility model relates to the field of sewage and sludge treatment equipment, and more specifically, it relates to a movable stirring device for use in building a clearing pool for sewage and wastewater. Background Art
[0002] Printing and dyeing processing requires the discharge of sewage and wastewater. During the process of sewage and sludge flowing through structures or treatment equipment such as stabilizing pools, regulating pools, anaerobic pools, hydrolysis acidification pools, sludge concentration pools, and sedimentation pools, due to factors such as insufficient or no stirring, organic particles, flocs, and microorganisms in the sewage and wastewater will settle to the bottom of the pool, corners, and other areas. As time goes by, an accumulation area of tens of centimeters or even meters high will often form, that is, an accumulated sludge layer. The accumulated sludge layer lacks oxygen supply and is basically in anoxic and anaerobic state. The anaerobic and facultative anaerobic microorganisms growing and breeding in the accumulated sludge layer will decompose some of the organic matter in the mud layer into methane, hydrogen sulfide, and other substances. Some of the products will float above the sewage level in the form of bubbles, and some will be sealed and compressed in the mud layer in the form of gas.
[0003] When the mud layer in the bottom accumulation area of the sewage structure is too thick or the treatment equipment and facilities in the pool need to be repaired, the sewage treatment plant or enterprise sewage treatment station must first clean up the sewage and thick mud layer in the structure or equipment. The conventional pool cleaning method is generally to hoist in submersible sewage pumps, mud pumps and other equipment and facilities or use the mud pump installed in the pool to pump out the sewage and mud in the sewage structure and the mud layer in the accumulation area. The sewage is often discharged out of the pool first due to its good fluidity; part of the sludge in the accumulation layer is discharged out of the pool with the sewage, and part of it needs to be flushed and diluted with water before it can flow to the pumping area and then be discharged out of the pool. However, the time for flushing and dilution with water is slow and the effect is not very ideal. There are always some areas where the sludge layer is still accumulated and difficult to be cleaned out of the pool. Even if the flushing is more thorough, it is extremely difficult to clean up all the sludge in the pool by mechanical equipment. Under such circumstances, when the pool cleaning personnel enter the bottom of the pool to clean the pool or perform maintenance work, if they accidentally step on the mud layer that contains hydrogen sulfide gas, the hydrogen sulfide gas instantly released from the mud layer may cause fatal effects of poisoning and suffocation to the operators. Although the operators can be required to wear isolation respirators to enter the pool for work, isolation respirators are often inconvenient to use and affect work efficiency. Operators tend to take risks to enter the pool for work under the influence of fluke psychology, which easily leads to production safety accidents. Therefore, in order to solve the above technical problems, it is necessary to provide a movable aeration and stirring device to overcome the above defects in the prior art. Utility Model Content

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] Embodiment: A movable stirring device, such as Figure 1 As shown, it includes a float 1, which can float on the sewage liquid surface and is used to bear the gravity of the entire stirring device. The float 1 is provided with a stirring mechanism, which includes a mounting seat 2 fixedly connected to the float 1, a mounting rod 3 is slidably connected to the mounting seat 2, and a fixing member 4 for fixing the mounting rod 3 is provided on the mounting seat 2, so that the relative position of the mounting rod 3 and the mounting seat 2 can be adjusted and fixed. A stirrer 5 is provided at the bottom of the mounting rod 3, and the stirrer 5 can stir the sewage and sludge layer, so that the toxic gas such as hydrogen sulfide sealed in the sludge is released and discharged, so as to avoid accidental poisoning when the operator goes down to the pool to clean the sludge at the bottom of the pool, and can provide a safe working environment for the operator. The angle of the stirrer 5 is adjustable. When in use, the length of the mounting rod 3 below the mounting seat 2 can be controlled according to the depth of the sewage pool, which can be better applicable to sewage pools of different depths, and the angle-adjustable stirrer 5 can also generate water flows in different directions, more comprehensively stir the sludge at the bottom of the sewage pool, and have a better use effect.
[0020] like Figure 2 As shown, a propeller 6 is provided on the float 1. The propeller 6 includes a motor and a blade fixed to the output end of the motor. The propeller 6 can provide power for the float 1, so that the stirring device moves on the water surface.
[0021] like Figure 1 As shown, the fixing member 4 is threadedly connected to the mounting seat 2. When fixed, one end of the fixing member 4 abuts against the mounting rod 3, and the other end is provided with a hand-tightening handle 7. The fixing member 4 can be moved by tightening the hand-tightening handle 7. The mounting rod 3 can be moved up and down relative to the mounting seat 2 by loosening the fixing member 4. When the fixing member 4 is in a suitable position, the fixing member 4 can be tightened by tightening the hand-tightening handle 7 so that one end of the fixing member 4 abuts against the mounting rod 3, thereby fixing the mounting rod 3 relative to the mounting seat 2.
[0022] like Figure 1As shown, a first fixed seat 8 and a second fixed seat 9 are provided at the bottom of the mounting rod 3, the bottom end of the agitator 5 is rotatably connected to the first fixed seat 8, and a push cylinder 10 is rotatably connected to the second fixed seat 9, and the output end of the push cylinder 10 is rotatably connected to the middle part of the agitator 5. The push cylinder is one of a hydraulic cylinder, a pneumatic cylinder, an electric cylinder or a manual push rod, all of which can push the middle part of the agitator 5. When in use, the angle of the agitator 5 can be adjusted by adjusting the length of the output end of the push cylinder 10, so that the agitator 5 can generate water flows in different directions, thereby achieving better use effects.
[0023] like Figure 1 As shown, a suspension rope 11 for the stirring device is connected to the float 1, and the suspension rope 11 can be hung so that the stirring device can be taken and placed on the water surface.
[0024] like Figure 1 As shown, two binding ropes 12 for fixing the stirring device are connected to the float 1. When the stirring device moves to the working water area, the two binding ropes 12 can be respectively tied to railings or stones. More specifically, in the tied state, the angle bisector formed by the extension lines of the two binding ropes coincides with the water flow direction formed by the stirrer, so that the stirring device works in a fixed working area, preventing the reverse thrust generated by the stirrer from causing the stirring device to move.
[0025] like Figure 1 As shown, the float ring 1 is made of foam material, more specifically, the float ring 1 is made of PE foam, which has good corrosion resistance and can ensure the durability of the float ring 1.
