Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage technology, and in particular to an environmentally friendly water supply and drainage clarification device. Background Technology

[0002] In the field of water treatment engineering, flocculation clarification is a key step in removing suspended solids and colloidal substances from water. With increasingly stringent environmental protection requirements and continuously rising energy costs, improving flocculation reaction efficiency while reducing energy consumption has become a key focus of water treatment equipment research and development. Especially in municipal water supply and industrial wastewater treatment scenarios, traditional clarification equipment is difficult to adapt to the differentiated flow state requirements of each stage of the flocculation reaction, and there is an urgent need to develop new energy-saving and efficient clarification devices to meet the technical requirements of modern water treatment.

[0003] Traditional water supply and drainage clarification equipment often adopts a relatively simple stirring and filtration mode in terms of mechanical structure. In the stirring stage, it is usually equipped with stirring blades at a fixed angle. The motor drives the stirring blades to rotate at a constant speed to achieve the mixing of sewage and chemicals. The technical principle is that by rotating the stirring blades, the blades push the liquid, causing the sewage and chemicals to flow and mix in the reaction space. With the help of the viscosity and turbulence between the liquids, uniform dispersion is gradually achieved.

[0004] However, the non-adjustable angle of the stirring blades in traditional equipment has drawbacks. During the flocculation reaction, different stages have different requirements for the stirring effect. In the early stage of the flocculation reaction, strong shear force is needed to quickly and evenly disperse the agent into the wastewater so that the agent can fully contact the colloids in the wastewater and promote the destabilization of the colloids. However, the traditional fixed-angle stirring blades are difficult to generate a sufficiently strong radial shear force, resulting in insufficient agent dispersion and poor colloid destabilization, which affects the subsequent flocculation reaction. Therefore, an environmentally friendly water supply and drainage clarification equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an environmentally friendly water supply and drainage clarification device, which aims to improve the problem that different stages of the flocculation reaction process have different requirements for the stirring effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly water supply and drainage clarification device, comprising a reaction tank, an inlet and a delivery pipe fixedly connected to the inner wall of the reaction tank, a sedimentation tank fixedly connected to the outer wall of the delivery pipe, an inclined plate fixedly connected to the inner wall of the sedimentation tank, an outlet pipe fixedly connected to the inner wall of the inclined plate, a filter plate installed inside the outlet pipe, a valve fixedly connected to one end of the outlet pipe, a limit ring installed above the reaction tank, and a limit component installed on the inner wall of the limit ring;

[0007] The limiting assembly includes a limiting rod, a limiting block one, and a rotating block. The outer wall of the limiting rod is slidably connected to the inner wall of the limiting ring. The inner wall of the limiting block one is threadedly connected to the outer wall of the limiting rod. The outer wall of the rotating block is fixedly connected to one end of the limiting rod. A motor is provided below the reaction vessel. A connecting block two is fixedly connected to the output end of the motor. A connecting rod one is provided on the inner wall of the connecting block two. An adjusting assembly is provided on the outer wall of the connecting rod one.

[0008] Furthermore, the adjusting assembly includes a first connecting block, a sleeve, and a third connecting block. The inner wall of the first connecting block is threadedly connected to the outer wall of the first connecting rod. The inner wall of the sleeve is rotatably connected to the outer wall of the first connecting block. The outer wall of the third connecting block is fixedly connected to the outer wall of the sleeve. A stirring blade is rotatably connected to the outer wall of the third connecting block. The outer wall of the stirring blade is rotatably connected to the outer wall of the second connecting block. A fixing rod is fixedly connected to the outer wall of the second connecting block. The outer wall of the fixing rod is fixedly connected to the inner wall of the sleeve. The outer wall of the first connecting rod is fixedly connected to the inner wall of the handwheel. The rotating block is disposed on the outer wall of the handwheel.

[0009] Furthermore, the limiting block is attached to the outer wall of the limiting ring, and the outer wall of the water outlet pipe is fixedly connected to the fixing block.

[0010] Furthermore, a second fixing block is fixedly connected to the upper surface of the first fixing block, and a second limiting block is slidably connected to the inner wall of the second fixing block.

[0011] Furthermore, the outer wall of the limiting block two is slidably connected to the fixing block three and the connecting block four. The lower surface of the fixing block three is fixedly connected to the upper surface of the fixing block one. The outer wall of the connecting block four is fixedly connected to the filter plate. The filter plate and the outer wall of the connecting block four are slidably connected to the inner wall of the fixing block three and the water outlet pipe.

[0012] Furthermore, a spring is provided on the outer wall of the connecting block four, and one end of the spring is attached to the outer wall of the fixing block three.

[0013] Furthermore, a connecting rod is rotatably connected to the inner wall of the limiting block two, and the outer wall of the connecting rod two is fixedly connected to the inner wall of the fixing block two.

[0014] Furthermore, a connecting seat two is fixedly connected to the outer wall of the limiting block two, a spring two is fixedly connected to the outer wall of the connecting seat two, a connecting seat one is fixedly connected to one end of the spring two, and the outer wall of the connecting seat one is fixedly connected to the inner wall of the fixing block two.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the equipment achieves flexible adjustment of the tilt angle of the stirring blades through the linkage of components such as the handwheel and connecting rod. When the angle is small, a strong radial shear force is generated, which is suitable for the dispersion of the agent and the destabilization of the colloid in the early stage of the flocculation reaction. When the angle is large, an axial circulation flow is formed to meet the needs of floc growth in the middle and later stages. This targeted adjustment makes the wastewater and the agent mix more evenly, improves the flocculation reaction efficiency, shortens the stirring reaction time, and reduces the energy consumption of the motor. At the same time, the fixing rod ensures that the angle is stable and does not shift after adjustment, avoiding energy waste caused by ineffective stirring, and further enhancing the energy-saving and environmental protection effect.

[0017] 2. In this utility model, the filter plate can be disassembled simply by pressing the limiting block two. By rotating the limiting block two, the limiting block four can be released, and the filter plate will pop out under the action of the spring one. No tools are required throughout the process. After the limiting block two is released, the spring two will drive it to automatically reset, ensuring that the reinstallation is accurate and firm. This design makes it easy to clean the trapped impurities on the filter plate in time, avoid clogging and affecting the water output efficiency. At the same time, it is convenient to replace the filter plate with a filter plate of different pore size according to the water quality, ensure the stability of the filtration effect of the clarified liquid, and reduce maintenance costs.

[0031] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7Limiting block 12 is attached to the outer wall of limiting ring 3.

Pressing releases the limiting. A fixing block 3 22 and connecting block 4 24 are slidably connected to the outer wall of limiting block 26. When the limiting is released, connecting block 4 24, under the action of spring 1 25, causes filter plate 23 to pop out, facilitating disassembly. The lower surface of fixing block 3 22 is fixedly connected to the upper surface of fixing block 1 20. A filter plate 23 is fixedly connected to the outer wall of connecting block 4 24. Filter plate 23 and the outer wall of connecting block 4 24 are slidably connected to fixing block 3 22 and the inner wall of water outlet pipe 10. A spring 1 is provided on the outer wall of connecting block 4 24. 25. When the filter plate 23 is released from its limit, spring 25 causes the filter plate 23 to pop out through its own elasticity, achieving quick disassembly. One end of spring 25 is attached to the outer wall of fixed block 3 22. The inner wall of limit block 2 26 is rotatably connected to connecting rod 2 30.

The outer wall of connecting seat 1 27 is fixedly connected to the inner wall of fixed block 2 21.

[0032] Specifically, there are two fixing blocks, 21 and 22, on the fixing block 1 outside the water outlet pipe 10. The limiting block 26 inside the fixing block 21 rotates around the connecting rod 2 30 and cooperates with the spring 28 on the connecting seat 1 27 and the connecting seat 2 29 to limit the connecting block 4 24. The connecting block 4 24 is connected to the filter plate 23 and the spring 1 25. Pressing the limiting block 26 can release the limit, and the spring 1 25 will cause the filter plate 23 to pop out, realizing quick disassembly and assembly, and facilitating cleaning and replacement.

[0033] Working principle: When using this equipment, firstly, the wastewater and reagents are transported from the inlet 2 to the reaction tank 1. Start the motor 9 to drive the connecting block 17 to rotate, so that the stirring blades 16 on the connecting block 17 can stir and mix the wastewater and reagents. If it is necessary to adjust the angle of the stirring blades 16, first rotate the limiting block 12 to allow the limiting rod 6 to drive the rotating block 5 to slide out of the limiting groove of the limiting ring 3. Then rotate the handwheel 4 to drive the connecting rod 13 to rotate, causing the connecting block 14 on the connecting rod 13 to slide up and down. In turn, the sleeve 15 outside the connecting block 14 drives the connecting block 18 to slide up and down synchronously, so that the stirring blades 16 can stir and mix the wastewater and reagents. The stirring blade 16 rotates on the connecting block 2 17 to adjust the angle. The fixing rod 31 connects the sleeve 15 and the connecting block 2 17 to prevent the connecting block 14 from sliding up and down when the motor 9 rotates. After the angle adjustment is completed, the limiting rod 6 is inserted into the limiting ring 3 and the limiting block 12 is tightened to fix it. When the stirring blade 16 is tilted at a small angle, it generates a strong radial shear force, which is suitable for the initial stage of flocculation reaction. When the angle is large, the axial thrust is the main force, forming a slow up and down circulation flow, which is suitable for the middle and late stages of flocculation reaction. This improves the reaction efficiency, shortens the stirring reaction time, and achieves the effect of energy saving and environmental protection.

[0034] After the reaction, the wastewater enters the sedimentation tank 8 through the conveying pipe 7. Under the action of gravity, the flocs sink to the bottom of the tank to form sludge. The inclined plate 19 can accelerate the sedimentation due to its tilt angle. The clarified liquid is discharged after being filtered by the filter plate 23 in the outlet pipe 10 by opening the valve 11.

[0035] If it is necessary to disassemble, clean or replace the filter plate 23, press the limiting block 26 in the fixing block 21 to make it rotate around the connecting rod 20, stretching the spring 28 fixed in the connecting seat 29 and the connecting seat 1 27, releasing the limiting on the connecting block 4 24. At this time, the spring 1 25 on the connecting block 4 24 will drive the filter plate 23 to pop out of the water pipe 10 and the fixing block 3 22, realizing quick disassembly and assembly. After releasing the limiting block 26, the stretched spring 28 will drive it to automatically reset.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
