Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment agent spraying device in a wastewater tank. Background Technology

[0002] By spraying wastewater treatment agents, pollutants such as suspended solids, colloids, and microorganisms in wastewater can be removed, thereby increasing the recycling value of wastewater or preventing discharge that pollutes the environment.

[0003] During the spraying of wastewater treatment agents, various methods are used to accelerate the integration of the agent into the wastewater in order to improve the efficiency of wastewater purification. The most common method is to agitate the wastewater, allowing the concentrated sprayed agent to quickly spread throughout the wastewater tank, thereby accelerating the integration process.

[0004] In existing technologies, the agitation effect is mainly generated by increasing the rotation of a single object. However, the agitation range is small, the diffusion is slow, and it can lead to the formation of vortices, causing sewage overflow. Utility Model Content

[0005] The purpose of this invention is to provide a sewage treatment agent spraying device for sewage tanks, which can generate a water flow that diffuses from the center outwards, allowing the sewage treatment agent to spread rapidly within the sewage tank.

[0008] The outer casing includes a side wall and a bottom wall. The side wall is fitted onto the propeller and is fixedly connected to a baffle plate. The bottom wall is fixedly connected to the propeller from below. A gap is left between the side wall and the bottom wall to form a water outlet.

[0009] A sprayer that releases wastewater treatment agent toward a propeller;

[0010] The propeller and outer casing gradually increase in size from top to bottom and are conical. In operation, sewage enters the gap between the baffles from above, and under the action of centrifugal force generated by the rotation of the propeller, the sewage is discharged through the outlet along the side wall.

[0011] Preferably, the lower end diameter of the sidewall is larger than the diameter of the bottom wall, the bottom wall is fixedly connected to the rotating rod and the baffle plate, and the lower end of the sidewall and the lower surface of the bottom wall are flush to form a downward-facing water outlet.

[0012] Preferably, the top of the sidewall is higher than the water baffle.

[0013] Preferably, the propeller further includes a partition plate, the partition plate is cylindrical, the baffle plate is evenly distributed along the outer wall of the partition plate and the baffle plate is fixedly connected to the partition plate, the bottom wall is annular and the inner wall of the bottom wall is fixedly connected to the outer wall of the partition plate, and the rotating rod is fixedly connected to the inner wall of the partition plate through a connecting rod.

[0015] Preferably, the propeller further includes auger blades, which are integrally formed on the rotating rod, and the partition plate is integrally formed and sleeved on the outside of the auger blades.

[0016] Preferably, the lower end diameter of the sidewall is equal to the diameter of the bottom wall, the bottom wall is fixedly connected to the rotating rod, and the lower end of the sidewall is higher than the upper surface of the bottom wall to form an outlet with the opening direction facing outward.

[0019] Preferably, the wastewater treatment agent spraying device in the wastewater tank further includes a drive motor, the drive end of which faces downward and is fixedly connected to the rotating rod.

[0020] The technical solution of this utility model uses the rotation of the propeller to accelerate the sewage located between the baffles under the action of centrifugal force. The direction of water flow is controlled by the change of the shell shape, and the acceleration effect of water flow is ensured by the height of the shell. Finally, a water flow that diffuses from the center outwards is generated to rapidly diffuse the sewage treatment agent in the sewage tank. At the same time, the shell can also prevent the propeller rotation from causing the generation of vortices. Attached Figure Description

[0032] Combination Figures 1 to 5 As shown, the wastewater treatment agent spraying device in the wastewater tank provided by this utility model includes a propeller 1, a shell 2, and a sprayer 3.

[0033] Combination Figures 1 to 5 As shown, the propeller 1 includes a rotating rod 11 and a baffle plate 12. The baffle plate 12 is evenly distributed along the cylindrical surface of the rotating rod 11. The rotating rod 11 and the baffle plate 12 are fixedly connected. The propeller 1 is placed vertically and rotates along the vertical rotating rod 11. The outer shell 2 includes a side wall 21 and a bottom wall 22. The side wall 21 is fitted onto the propeller 1 and is fixedly connected to the baffle plate 12. The bottom wall 22 is fixedly connected to the propeller 1 from below. A gap is left between the side wall 21 and the bottom wall 22 to form a water outlet. The sprayer 3 releases sewage treatment agent toward the propeller 1. The propeller 1 and the outer shell 2 gradually increase in size from top to bottom and are conical. In the working state, sewage enters the gap between the baffle plates 12 from above. Under the action of the centrifugal force generated by the rotation of the propeller 1, the sewage is discharged along the side wall 21 through the water outlet.

[0034] In this embodiment, the rotation of the propeller 1 accelerates the sewage located between the baffles 12 under the action of centrifugal force. The direction of the water flow is controlled by the change of the shape of the outer shell 2, and the acceleration effect of the water flow is ensured by the height of the outer shell 2. Finally, the water flow that diffuses from the center outwards is generated to rapidly diffuse the sewage treatment agent in the sewage tank. At the same time, the outer shell 2 can also prevent the rotation of the propeller 1 from causing the generation of vortices.

[0035] In some embodiments, combined with Figure 1As shown, the lower diameter of the side wall 21 is larger than the diameter of the bottom wall 22. The bottom wall 22 is fixedly connected to the rotating rod 11 and the baffle plate 12. The lower end of the side wall 21 and the lower surface of the bottom wall 22 are flush to form a downward-facing water outlet. Sewage can be smoothly discharged from the outer shell 2 after being accelerated along the side wall 21, and the speed loss during the water discharge process is low.

[0036] In some embodiments, combined with Figures 1 to 3 As shown, the top of the sidewall 21 is higher than the baffle plate 12. The increased height of the sidewall 21 helps the sewage to enter the gap between the baffle plates 12 more smoothly, and prevents the rotation of the propeller 1 from inhibiting the entry of sewage.

[0037] In some embodiments, combined with Figure 2 As shown, the propeller 1 also includes a partition plate 13, which is cylindrical. The baffle plates 12 are evenly distributed along the outer wall of the partition plate 13 and are fixedly connected to the partition plate 13. The bottom wall 22 is annular and its inner wall is fixedly connected to the outer wall of the partition plate 13. The rotating rod 11 is fixedly connected to the inner wall of the partition plate 13 through a connecting rod. After the partition plate 13 is set up, sewage can enter the gap between the baffle plates 12 through the through hole in the center of the partition plate 13, making it easier for sewage to enter.

[0038] In some embodiments, combined with Figure 2 , Figure 3 As shown, the top surfaces of the sidewall 21, the baffle plate 12, and the partition plate 13 are flush and present a concave conical surface. This structure achieves the effect of raising the sidewall 21, making the structural edges more flush and the structural strength higher.

[0039] In some embodiments, combined with Figure 3 As shown, the propeller 1 also includes a auger blade 14, which is integrally formed on the rotating rod 11. The partition plate 13 is integrally formed and sleeved on the outside of the auger blade 14. The auger blade 14 can accelerate the flow rate of sewage in the partition plate 13 and accelerate the circulation of water.

[0040] In some embodiments, combined with Figure 2 , Figure 3 As shown, the lower diameter of the side wall 21 is equal to the diameter of the bottom wall 22. The bottom wall 22 is fixedly connected to the rotating rod 11. The lower height of the side wall 21 is higher than the upper surface of the bottom wall 22, forming an outlet with the opening direction facing outward. The horizontally opened outlet helps to increase the range of water flow outward.

[0041] In some embodiments, combined with Figures 1 to 3As shown, the lower end of the side wall 21 is lower than the water baffle 12. The side wall 21 covering the water baffle 12 can ensure that the rotation of the water baffle 12 will not cause the generation of vortices.

[0042] In some embodiments, combined with Figure 4 As shown, the sprayer 3 includes an infusion pipe and a nozzle. One end of the infusion pipe is bent into a circle. The nozzle is located on the bent section of the infusion pipe and is evenly distributed along the infusion pipe. The bent section of the infusion pipe is located directly above the baffle plate 12. The sprayer 3 with its specific shape can more easily deliver the sewage treatment agent into the gap between the baffle plates 12.

[0043] In some embodiments, combined with Figure 5 As shown, the sewage treatment agent spraying device in the sewage tank also includes a drive motor 4. The drive end of the drive motor 4 faces downward and is fixedly connected to the rotating rod 11. The drive motor 4 acts as a drive element to drive the rotating rod 11 to rotate, ensuring the smooth operation of the device.

[0044] Working process: The propeller 1 sinks into the sewage and begins to rotate. The sewage located in the gap formed by the baffle plate 12 and the side wall 21 is pushed by the propeller 1. Under the action of centrifugal force, the sewage hits the side wall 21 and flows along the side wall 21. The shape of the top is smaller and the bottom is larger, which ensures that the sewage flows downward. At the same time, the sewage will enter the gap formed by the baffle plate 12 and the side wall 21 from the top. The sewage is accelerated under the action of the propeller 1. After the accelerated sewage is discharged from the outer shell 2, it forms a water flow that diffuses from the center outward. The sprayer 3 puts the sewage treatment agent into the gap formed by the baffle plate 12 and the side wall 21. Finally, the sewage treatment agent diffuses rapidly in the sewage tank under the action of the water flow.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
