Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a dosing device for a dephosphorization sedimentation tank. Background Art

[0002] Phosphorus-containing wastewater primarily originates from domestic sewage, industrial wastewater, and livestock wastewater. This includes various detergents, manure, phosphate fertilizers, pharmaceuticals, metal surface treatment, and the food industry. Large-scale discharge of phosphorus-containing wastewater can cause severe algal blooms and red tides in nature, so it must be treated before normal discharge.

[0003] Among them, the treatment methods for phosphorus-containing wastewater mainly include chemical methods, biological methods and adsorption methods, and the main purpose is to remove phosphorus from sewage. Among them, the chemical precipitation method mainly refers to adding chemical reagents to sewage to react with phosphorus ions and precipitate. Therefore, depending on the type of sewage, corresponding reagents need to be used, and there are certain requirements for the order of adding reagents. In the actual operation process, the corresponding reagents are added according to the progress of sewage treatment and the order of ion precipitation in the water. However, the reagents need to be fully dispersed in the sewage in order to be able to fully combine with the ions. At this time, the solution needs to be stirred to a certain extent, but the stirring process will destroy the original precipitation process, which will prolong the precipitation time and reduce the efficiency of the corresponding sewage treatment. Therefore, a more reasonable dosing device can be set up. Utility Model Content

[0026] Example

[0027] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 5 As shown, the dosing device for the dephosphorization sedimentation tank of this embodiment includes a tank body 10, a support rod 23 horizontally arranged on the upper side of the tank body 10, a plurality of spray pipes 21 connected to the lower side of the support rod 23, a water spray hole 22 opened on the side wall of the spray pipe 21, a liquid supply device connected to the spray pipe 21, and a first driving device for driving the support rod to move along the length direction of the tank body 10; the support rod 23 is perpendicular to the length direction of the tank body 10, and the plurality of spray pipes 21 are distributed along the length direction of the support rod 23; the upper end of the spray pipe 21 is connected to the support rod 23. Specifically, during use, when it is necessary to add medicine, a lifting device can be used (there is no requirement for the lifting device, and a conventional one such as an electric hoist can be used) to lift the support rod 23 onto the pool body 10 and connect it to the first driving device. At this time, the medicine is supplied to the spray pipe 21 through the liquid supply device and sprayed out through the water hole 22. In the process of spraying the medicine, the first driving device drives the spray pipe 21 to move slowly and uniformly along the length direction of the pool body 10. This not only can evenly disperse the medicine in the sewage, but also can minimize the agitation of the sewage and not disrupt its sedimentation process. When no medicine is needed, the spray pipe 21 does not need to be immersed in the sewage, so that the spray pipe 21 will not be corroded by the sewage. The whole process has a high degree of automation, and the addition of medicine is more uniform and standardized.

[0028] The spray pipe 21 in this embodiment has a fusiform cross-section along its horizontal axis. Water spray holes 22 are located on adjacent sides of the spray pipe 21. Specifically, the fusiform shape of the spray pipe 21 minimizes disturbance of the sewage as it moves through it. Placing the water spray holes 22 on both sides of the spray pipe 21 ensures more thorough dispersion of the agent.

[0029] In this embodiment, a slider 24 slides within the spray pipe 21. This slider 24 is connected to a water inlet pipe 25, the upper end of which passes through the spray pipe 21 and connects to the liquid supply device. A through-hole 26 is provided at the junction of the slider 24 and the water inlet pipe 25. Specifically, the slider 24 limits the height at which the spray pipe 21 sprays the agent, ensuring that the maximum height is near the surface of the sewage. By adjusting the position of the slider 24 and feeding the agent through the water inlet pipe 25 to the bottom of the slider 24, the agent is prevented from spilling out of the water spray hole 22 above the slider 24.

[0030] The liquid supply device in this embodiment includes a water pump and a water inlet manifold 27 connected to the water pump. The water inlet manifold 27 is horizontally arranged above the support rod 23, and multiple water inlet pipes 25 are connected to the water inlet manifold 27. A second drive device is provided between the water inlet manifold 27 and the support rod 23 for driving the water inlet manifold 27 up and down. The second drive device includes an electric push rod 28 connected to the support rod 23, and the telescopic rod of the electric push rod 28 is connected to the water inlet manifold 27. A pair of electric push rods 28 are provided, one at each end of the support rod 23. Specifically, the spray height of the agent is adjusted by the electric push rods 28, wherein the electric push rods 28 push the water inlet manifold 27 upward, which in turn pulls the slider 24 upward through the water inlet pipe 25 to achieve the effect of increasing the spray height, and vice versa.

[0031] In this embodiment, a pair of first drive devices are provided, one at each end of the support rod 23. The first drive device includes a screw 32 parallel to the length of the tank body 10, a motor 31 for driving the screw 32 to rotate, a nut 33 threadedly connected to the screw 32, a fixing block 34 fixedly connected to the nut 33, a slot 35 provided on the upper side of the fixing block 34, and a block 36 provided at the end of the support rod 23. The block 36 is detachably provided in the slot 35. Specifically, the screw 32 and the nut 33 form a ball screw structure. The motor 31 drives the screw 32 to rotate, thereby driving the support rod 23 to move through the nut 33, the fixing block 34, and the block 36. When not in use, the block 36 can be removed from the slot 35. It should be noted that the block 36 needs to be fixed in the slot 35 with bolts.

[0032] In summary, the dosing device for the dephosphorization sedimentation tank of this embodiment, when in use, when dosing is required, the support rod 23 can be hoisted to the tank body 10 by using a lifting device and connected to the first driving device. At this time, the agent is supplied to the spray pipe 21 through the liquid supply device and sprayed out through the water hole 22. In the process of spraying the agent, the first driving device drives the spray pipe 21 to move slowly and uniformly along the length direction of the tank body 10, so that not only the agent can be evenly dispersed in the sewage, but also the agitation of the sewage can be minimized and its sedimentation process will not be destroyed. When dosing is not required, the spray pipe 21 does not need to be immersed in the sewage, so that the spray pipe 21 will not be corroded by the sewage. The whole process has a high degree of automation, and the addition of the agent is more uniform and standardized.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
