Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater treatment agent spraying device for wastewater treatment. Background Technology

[0002] Spraying treatment agents into treatment tanks is a common treatment method in wastewater treatment. Currently, most treatment agents sprayed into treatment tanks are inorganic flocculants such as aluminum salts and iron salts. These treatment agents are mostly small-particle powder solids, which need to be diluted and dissolved to make a treatment solution. The treatment solution is then sprayed onto the wastewater on the surface of the treatment tank using a spraying device.

[0003] A prior art patent, CN222446903U, describes a wastewater treatment agent spraying device. This device includes a base plate, a mixing tank fixedly connected to the top of the base plate, a motor fixedly connected to the top of the mixing tank, a stirring assembly at the motor's output end, an eccentric wheel fixedly connected to the outside of the stirring assembly, a sliding plate slidably connected to the right side of the mixing tank, a filter plate fixedly connected to the right side of the sliding plate, and multiple sleeves fixedly connected to the right side of the sliding plate. Each of the sleeves has a sliding cylinder slidably connected to its outside, and each sliding cylinder has a limiting ring slidably connected to its inside. This device allows for the screening of wastewater treatment agents, thus preventing clumped wastewater treatment agents from failing to dissolve effectively. However, in practical use, it still has the following shortcomings: In practice, this device, by pushing a trolley to move around the wastewater tank and spraying the treatment agent into the tank from the nozzle, can only spray the treatment agent at the edge of the wastewater tank. The middle of the wastewater tank or other areas far from the edge do not have sufficient treatment agent coverage, resulting in uneven wastewater treatment effects.

[0004] Therefore, there is a need for a wastewater treatment agent spraying device to solve the problem of uneven spraying caused by existing spraying devices that can only spray the treatment agent at the edge of the wastewater tank. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment agent spraying device for wastewater treatment, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewage treatment agent spraying device for sewage treatment, comprising a sewage tank, a first convex frame fixedly connected to the top of the sewage tank, threaded rods rotatably connected to the inner walls of both sides of the first convex frame near the front end, limit rods fixedly connected to the inner walls of both sides of the first convex frame near the rear end, a ball nut seat rotatably connected to the outer wall of the threaded rod, a limit sleeve slidably connected to the outer wall of the limit rod, a connecting block fixedly connected to the outer wall of the ball nut seat and the outer wall of the limit sleeve, a servo motor corresponding to the threaded rod fixedly connected to one side of the first convex frame, a spraying mechanism provided at the bottom of the connecting block, and a straight rack corresponding to the spraying mechanism fixedly connected to the lower surface of the top of the first convex frame.

[0007] It should be noted in the solution that the first convex frame is located at the middle of the top of the sewage tank.

[0008] It is worth noting that the output end of the servo motor passes through one side of the first convex frame and is fixedly connected to the threaded rod.

[0009] Furthermore, the spraying mechanism includes a second convex frame fixedly connected to the bottom of the connecting block. A first rotating shaft is rotatably connected to the inner wall of one side of the second convex frame, and a second rotating shaft is rotatably connected to the inner wall of the other side of the second convex frame. A storage cylinder is fixedly connected between the first and second rotating shafts. A feeding port is fixedly connected to the front end of the storage cylinder. Multiple nozzles are fixedly connected to the bottom of the storage cylinder. Two support plates are fixedly connected to the outer wall of the first rotating shaft. A cylinder is fixedly connected near the top between the two support plates. A sleeve is slidably connected to the outer wall of the cylinder. A guide post is fixedly connected to the top of the sleeve. A turntable is fixedly connected to the top of the guide post. A follower post is fixedly connected to the top of the turntable. A gear is fixedly connected to the top of the follower post.

[0010] In a preferred embodiment, the top of the feed port is threaded with a cap, and each of the multiple nozzles is equipped with a solenoid valve.

[0011] In a preferred embodiment, the top of the guide post is fixedly connected to the bottom of the turntable near one side.

[0012] In a preferred embodiment, the follower column is rotatably connected to the top of the second convex frame, and the gear meshes with the spur rack.

[0013] Compared with the prior art, the wastewater treatment agent spraying device for wastewater treatment provided by this utility model has at least the following beneficial effects:

[0014] (1) By setting a servo motor to drive the threaded rod to rotate, and with the cooperation of the ball nut seat and the limit sleeve, the spraying mechanism can move flexibly on the top of the sewage tank, so that the spraying mechanism covers all positions of the sewage tank, ensuring that the treatment agent can be effectively sprayed to all areas of the sewage tank, thus improving the comprehensiveness of the treatment.

[0015] (2) By setting a rack and pinion to cooperate with the spraying mechanism, while the second convex frame moves with the connecting block, the gear rotates under the limit of the rack, so that the follower column drives the turntable to rotate, and the turntable drives the guide column to make a circular motion. With the cooperation of the sleeve, the cylinder drives the two support plates to swing back and forth, so that the first rotating shaft drives the storage cylinder to swing back and forth, so that multiple nozzles swing back and forth while moving left and right, further expanding the spraying coverage, ensuring more comprehensive spraying, avoiding local areas being ignored, and thus improving the overall efficiency of the treatment.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4This utility model provides a sewage treatment agent spraying device for sewage treatment, including a sewage tank 1. A first convex frame 2 is fixedly connected to the top of the sewage tank 1. Threaded rods 3 are rotatably connected to the inner walls of both sides of the first convex frame 2 near the front end. Limiting rods 4 are fixedly connected to the inner walls of both sides of the first convex frame 2 near the rear end. A ball nut seat 5 is rotatably connected to the outer wall of the threaded rod 3. A limiting sleeve 6 is slidably connected to the outer wall of the limiting rod 4. A connecting block 7 is fixedly connected to the outer walls of the ball nut seat 5 and the limiting sleeve 6. A servo motor 8 corresponding to the threaded rod 3 is fixedly connected to one side of the first convex frame 2. A spraying mechanism 9 is provided at the bottom of the connecting block 7. A straight rack 10 corresponding to the spraying mechanism 9 is fixedly connected to the lower top surface of the first convex frame 2.

[0023] Further as Figure 1 and Figure 2 As shown, it is worth noting that the first convex frame 2 is located at the top center of the sewage tank 1. The center position helps to ensure that the spraying mechanism 9 evenly covers the entire sewage tank 1 area, effectively improving the efficiency and effect of sewage treatment.

[0024] Further as Figure 1 and Figure 2 As shown, it is worth noting that the output end of the servo motor 8 passes through one side of the first convex frame 2 and is fixedly connected to the threaded rod 3, so that the servo motor 8 can drive the threaded rod 3 to rotate smoothly, providing driving force for the movement of the connecting block 7.

[0025] As can be seen from the above working process: by setting the servo motor 8 to drive the threaded rod 3 to rotate, with the cooperation of the ball nut seat 5 and the limit sleeve 6, the spraying mechanism 9 can move flexibly on the top of the sewage tank 1, so that the spraying mechanism 9 covers all positions of the sewage tank 1, ensuring that the treatment agent can be effectively sprayed to all areas of the sewage tank 1, and improving the comprehensiveness of the treatment.

[0026] Further as Figure 4As shown, it is worth noting that the spraying mechanism 9 includes a second convex frame 901 fixedly connected to the bottom of the connecting block 7. A first rotating shaft 902 is rotatably connected to the inner wall of one side of the second convex frame 901, and a second rotating shaft 903 is rotatably connected to the inner wall of the other side of the second convex frame 901. A storage cylinder 904 is fixedly connected between the first rotating shaft 902 and the second rotating shaft 903. A feed port 905 is fixedly connected to the front end of the storage cylinder 904. Multiple nozzles 906 are fixedly connected to the bottom of the storage cylinder 904. Two support plates 907 are fixedly connected to the outer wall of the first rotating shaft 902. The two support plates 907 are located near the top. A cylinder 908 is fixedly connected to the part of the spraying mechanism 9. A sleeve 909 is slidably connected to the outer wall of the cylinder 908. A guide post 910 is fixedly connected to the top of the sleeve 909. A turntable 911 is fixedly connected to the top of the guide post 910. A follower post 912 is fixedly connected to the top of the turntable 911. A gear 913 is fixedly connected to the top of the follower post 912. By setting a rack 10 to cooperate with the spraying mechanism 9, multiple nozzles 906 can swing back and forth while moving left and right, further expanding the spraying coverage area, ensuring more comprehensive spraying, avoiding local areas being ignored, and thus improving the overall efficiency of the treatment.

[0027] Further as Figure 4 As shown, it is worth noting that the top of the feed port 905 is threaded with a cap. The threaded connection of the cap can effectively seal the feed port 905, preventing the sewage treatment agent from leaking or external substances from entering the storage cylinder 904, keeping the inside of the equipment clean and reducing the risk of pollution. Each of the multiple nozzles 906 is equipped with a solenoid valve, which can precisely control the spraying time and amount as needed, realizing automated and intelligent spraying control. The start and stop of spraying can be controlled remotely or at timed intervals through the solenoid valve, avoiding waste and over-spraying.

[0028] Further as Figure 4 As shown, it is worth noting that the top of the guide post 910 is fixedly connected to the bottom of the turntable 911 near one side, ensuring that the turntable 911 can drive the guide post 910 to make circular motion, thereby providing driving force for the swing of the two support plates 907.

[0029] Further as Figure 4 As shown, it is worth noting that the follower column 912 is rotatably connected to the top of the second convex frame 901, and the gear 913 meshes with the rack 10. The gear 913 rotates under the limit of the rack 10, so that the follower column 912 can drive the turntable 911 to rotate, thereby providing power for the back-and-forth swing of the storage cylinder 904.

[0030] This solution has the following working process: In actual use, the mixed sewage treatment agent is added into the storage cylinder 904 through the feeding port 905. Multiple nozzles 906 are opened to spray the sewage treatment agent into the sewage tank 1. Then, the servo motor 8 is turned on to drive the threaded rod 3 to rotate. With the cooperation of the ball nut seat 5 and the limiting sleeve 6, the spraying mechanism 9 moves flexibly on the top of the sewage tank 1. While the second convex frame 901 moves with the connecting block 7, the gear 913 rotates under the limit of the rack 10, which causes the follower column 912 to drive the turntable 911 to rotate. The turntable 911 drives the guide column 910 to make a circular motion. With the cooperation of the sleeve 909, the cylinder 908 drives the two support plates 907 to swing back and forth, which causes the first rotating shaft 902 to drive the storage cylinder 904 to swing back and forth. This causes the multiple nozzles 906 to swing back and forth while moving left and right, further expanding the spray coverage area.

[0031] In summary: By setting the servo motor 8 to drive the threaded rod 3 to rotate, and with the cooperation of the ball nut seat 5 and the limit sleeve 6, the spraying mechanism 9 can move flexibly on the top of the sewage tank 1, allowing the spraying mechanism 9 to cover all positions of the sewage tank 1, ensuring that the treatment agent can be effectively sprayed to all areas of the sewage tank 1, thus improving the comprehensiveness of the treatment; by setting the rack and pinion 10 to cooperate with the spraying mechanism 9, multiple nozzles 906 can move left and right while swinging back and forth, further expanding the spraying coverage area, ensuring more comprehensive spraying, avoiding the neglect of local areas, and thus improving the overall efficiency of the treatment.
