Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a pipeline coagulant for sewage treatment. Background Art
[0002] The pipeline coagulator is a device that achieves uniform mixing of the fluid through a certain component or mixing element when the fluid flows through the pipeline, so that the added liquid can increase the overall mixing degree. Similar to the pipeline reactor, it can keep the reactant flow in a turbulent state, and ultimately allow the sewage to coagulate quickly in the pipeline.
[0003] However, the turbulence generated by the existing pipeline coagulant is usually at the bends of the pipeline. If turbulence is to occur in the straight flow, the overall pipeline structure needs to be further increased to increase the flow rate. If too many liquid pumps are installed in a longer pipeline coagulant, the overall floor space will be increased, which is not only not suitable for replenishing the liquid medicine in the pipeline, but also not suitable for long-term use of the coagulant, reducing the service life of the pipeline. Utility Model Content
[0004] In response to the above-mentioned existing technologies, the present invention provides a pipeline coagulant for sewage treatment, the main technical problem to be solved is how to increase the flow rate of a straight pipeline in the pipeline, thereby increasing the service life of the pipeline and the degree of mixing of sewage and liquid medicine in the pipeline.
[0005] To achieve the above-mentioned purpose, the technical solution of the embodiment of the present utility model is implemented as follows:
[0006] The outlet pipe is fixed to the second vertical rod, and the bottom of the U-shaped sewage pipe is arranged inside the base; the lateral distance of the U-shaped sewage pipe near the first section is greater than that of the U-shaped sewage pipe at the tail section, and the diameter of the U-shaped sewage pipe near the first section is greater than that of the U-shaped sewage pipe at the tail section, and the mixing pipe is a funnel-shaped structure.
[0007] Preferably, the mixing tube is a vertical structure, a dosing tube is connected to the side of the mixing tube, the dosing tube and the U-shaped sewage pipe are installed alternately on the left and right in the same plane of the mixing tube, the bottom of the mixing tube is connected to the U-shaped sewage pipe of the next section of the U-shaped pipe unit, and the mixing tube of the U-shaped pipe unit at the end is connected to the outlet pipe.
[0008] Preferably, there is also a mixing module inside the mixing tube that provides power based on the staggered structure. The mixing module is used to mix sewage and liquid medicine. The mixing module includes a rotating shaft. A fixed disk connected to a bearing is installed at the bottom end of the rotating shaft. The fixed disk is fixedly installed on the inner wall of the mixing tube. The top end of the rotating shaft is connected to the top bearing of the mixing tube. The surface of the rotating shaft is provided with rotating blades, and the rotating blades are a structure that is wide at the top and narrow at the bottom. The surface of the fixed disk is provided with through holes.
[0009] Preferably, a spiral blade is further provided between the fixed disk and the rotating blade, and the spiral blade is installed at the bottom end of the rotating shaft.
[0010] Preferably, each of the dosing tubes includes a liquid pump, and the number of the mixing tubes is at least two.
[0011] Preferably, the mixing tube is installed with a flange, which is used to seal the top of the mixing tube. The tilting rod is detachably connected to the first vertical rod and the second vertical rod respectively, and the left and right parts of the tilting rod can be symmetrically disassembled and installed.
[0012] Preferably, there are at least two fixing plates, and the through holes of the fixing plates are arranged in an up-and-down staggered manner.
[0013] The beneficial effect of the present invention is that by setting a mixing tube and improving the overall structural shape of the coagulant, multiple bending parts are kept in a fixed state. At the same time, the trapezoidal structure of the pipeline shape can also increase the flow rate provided by the gravitational potential energy. Combined with the continuously decreasing pipe diameter and the horizontal distance of the pipeline, the sewage inside the pipeline can always maintain a rapid circulation state, so that after turbulence is generated in the bending part, a turbulent effect can also be formed in the straight part.
[0014] The present invention further provides a funnel-shaped mixing tube structure, so that the liquid medicine and sewage pipes form a cross-staggered upper and lower connection structure on the surface of the mixing tube, thereby providing kinetic energy to the mixing module inside the mixing tube, so that the mixing module can fully mix the liquid medicine and sewage.

[0023] Example 1
[0024] Please refer to the attached Figure 1-2The present application provides a pipeline coagulant for sewage treatment, comprising a base 1, a first vertical rod 2, a second vertical rod 202 and an inclined rod 201 to form a trapezoidal structure, wherein the first vertical rod 2 is provided with multiple sections of curved U-shaped pipe units 3 on the inner side, and the multiple sections of the U-shaped pipe units 3 are connected in series, and the last section of the U-shaped pipe unit 3 is connected to the outlet pipe 6, the U-shaped pipe unit 3 comprises a U-shaped sewage pipe 301 and a mixing pipe 4, the upper end of the U-shaped sewage pipe 301 is connected to the side of the mixing pipe 4, and the mixing pipe 4 is used to add liquid medicine to the sewage; the bottoms of the multiple mixing pipes 4 are spaced apart along the inclined rod 201, the first vertical rod 2 is higher than the second vertical rod 202, and the inlet of the U-shaped pipe unit 3 in the first section is set near the first vertical rod 2, and the second vertical rod 202 is fixed with the outlet pipe 6, the U-shaped sewage pipe 301 is connected to the side of the mixing pipe 4, and the mixing pipe 4 is used to add liquid medicine to the sewage; The bottom of the pipe 301 is arranged inside the base 1; the lateral distance of the U-shaped sewage pipe 301 near the first section is greater than that of the U-shaped sewage pipe 301 at the tail section, and the diameter of the U-shaped sewage pipe 301 near the first section is greater than that of the U-shaped sewage pipe 301 at the tail section, and the mixing pipe 4 is a funnel-shaped structure; the height of the entire pipeline from the water inlet of the first section U-shaped pipe unit 3 to the outlet pipe 6 is gradually reduced, so that turbulence will occur inside the sewage when it passes through the multiple sections of U-shaped pipe units 3 quickly. The turbulence will make the liquid medicine and sewage mix more fully, and the vibration caused by the turbulence will be prevented because the bending parts are fixedly arranged. As the pipe diameter gradually decreases and the lateral distance is reduced, the trapezoidal structure will further increase the potential energy that the sewage can generate at the vertical height, and the reduced lateral pipe distance when the pipe diameter is reduced will reduce the loss of sewage power.
[0025] Furthermore, the mixing tube 4 is a vertical structure, and a dosing tube 401 is connected to the side of the mixing tube 4. The dosing tube 401 and the U-shaped sewage pipe 301 are staggered left and right in the same plane of the mixing tube 4. The bottom of the mixing tube 4 is connected to the U-shaped sewage pipe 301 of the next section of the U-shaped pipe unit 3, and the mixing tube 4 of the U-shaped pipe unit 3 at the end is connected to the outlet pipe 6; the sewage entering from the U-shaped sewage pipe 301 can be mixed with the liquid medicine through the mixing tube 4, and the power provided during mixing is mainly provided by the staggered dosing tube 401 and the U-shaped sewage pipe 301. Figure 4 As shown, the staggered structure forms a couple of water flows on the left and right sides and generates a downward spiral, so that the U-shaped sewage pipe 301 increases the overall flow rate based on the above means and increases the degree of mixing of the liquid medicine and sewage.
[0026] Furthermore, the dosing pipe 401 includes a liquid pump, and the number of the mixing pipes 4 is at least two, thereby increasing the water flow pressure output from the dosing pipe 401 and making the water pressure of the dosing pipe 401 close to the water pressure generated by the U-shaped sewage pipe 301.
[0027] Furthermore, there are at least two fixed plates 703, and the through holes 704 of the multiple fixed plates 703 are staggered up and down. The multiple fixed plates 703 can allow the sewage discharged from the mixing tube 4 to flow alternately in multiple different through holes, and the U-shaped sewage pipe at the end can produce turbulence even when the water pressure is relatively low.
[0028] The use process of this embodiment is as follows: connect sewage from the water inlet of the U-shaped sewage pipe 301 of the U-shaped pipe unit 3, such as Figure 1 As shown, due to the gravitational potential energy and the action of the water pump, the sewage enters the mixing tube 4 through the thicker pipe near the first vertical rod 2. Since the surface of the mixing tube 4 is also provided with a dosing tube 401, the dosing tube 401 and the U-shaped sewage pipe 301 are arranged in a staggered structure on the same plane, a downward spiral couple is formed inside the mixing tube 4, which not only promotes mixing between the sewage and the liquid medicine, but also increases the flow rate of the sewage.
[0029] Since the U-shaped pipe unit 3 has a trapezoidal structure and the diameter of the pipe gradually decreases, under the influence of gravitational potential energy and an external water pump, the liquid flow rate in the pipe will continue to accelerate when passing through the mixing pipe 4, causing turbulence in the sewage in the vertical U-shaped sewage pipe 301. Therefore, the sewage and the liquid medicine will be further mixed regardless of the bending part or the straight part of the U-shaped pipe unit 3. At the same time, the overall structure is also based on the designed acceleration structure, and a base 1 and an inclined rod 201 for fixing are also provided at the bending part, so that the part of the sewage that is prone to vibration in the pipe is clamped by the outer fixed structure, thereby reducing the vibration effect of the entire pipe and increasing the service life of the pipe.
[0030] Example 2
[0031] The difference from Example 1 is that Figure 3-4 As shown, there is also a mixing module inside the mixing tube 4 that is powered by an interlaced structure. The mixing module is used to mix sewage and liquid medicine. The mixing module includes a rotating shaft 7. A fixed disk 703 connected to a bearing is installed at the bottom end of the rotating shaft 7. The fixed disk 703 is fixedly installed on the inner wall of the mixing tube 4. The top of the rotating shaft 7 is connected to the top bearing of the mixing tube 4. The surface of the rotating shaft 7 is provided with rotating blades 701. The rotating blades 701 are arranged in a wide-upper-narrow-lower structure. The surface of the fixed disk 703 is provided with through holes 704. The couple formed in the interlaced structure will drive the rotating blades 701 to rotate. The rotating blades 701 are in a wide-upper-narrow-lower-form. The water flow will adhere to the structure of the rotating blades 701 and continuously transmit downward, thereby increasing the downward flow rate of sewage.
[0032] Furthermore, a spiral blade 702 is provided between the fixed disk 703 and the rotating blade 701, and the spiral blade 702 is installed at the bottom end of the rotating shaft 7; the spiral blade 702 allows the sewage transmitted by the rotating blade 701 to flow along the rotating blade 701 toward the through hole 704. The aperture of the through hole 704 is large, and the agglomerates after coagulation can also continue to flow downward at the through hole 704.
[0033] Furthermore, flanges 5 are installed at the top of the mixing tube 4 to seal the top of the mixing tube 4. The tilting rod 201 is detachably connected to the first vertical rod 2 and the second vertical rod 202, respectively. The left and right portions of the tilting rod 201 are symmetrically removable and removable. This allows the entire structure to be removed for maintenance by completely disassembling the tilting rod 201 and then individually removing the mixing tube 4 and all of the U-shaped sewage pipes 301 installed in sections, excluding the bend inside the base 1.
[0034] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The scope of protection of the present utility model should be based on the scope of protection of the claims.
