Description

Technical Field

[0001] This utility model relates to the technical field of sewage tank dosing hopper with a viewing window, specifically a sewage tank dosing hopper with a viewing window. Background Technology

[0002] In the field of wastewater treatment, chemical dosing is a crucial step in regulating water quality, removing pollutants, and achieving compliant discharge. In traditional wastewater treatment processes, chemical dosing typically relies on manual operation or simple metering equipment. The dosing hopper, as the core component of the chemical dosing system, is mainly used for storing, metering, and transporting chemical agents such as flocculants, disinfectants, and pH adjusters. Its design must consider sealing performance, corrosion resistance, metering accuracy, and compatibility with subsequent dosing devices (such as pumps and agitators).

[0003] Existing wastewater treatment systems use a fixed dosing hopper with a viewing window mounted on top of the mixing unit. While this facilitates monitoring of remaining chemicals, it has significant drawbacks: due to the fixed position of the hopper and its large inlet diameter, the chemicals flow at high speed under gravity, easily leading to high-concentration accumulation in localized areas of the mixing unit. This is especially problematic when adding powdered flocculants or high-viscosity chemicals, as the rapidly falling chemicals do not make sufficient contact with the wastewater. Furthermore, the uneven distribution of shear force within the mixing unit further exacerbates the problem, easily causing chemical agglomeration. Agglomerated chemicals not only reduce reaction efficiency and increase the risk of clogging in subsequent equipment but also result in incomplete dissolution and wasted chemicals, impacting the overall stability and economic efficiency of wastewater treatment. Therefore, we propose a wastewater treatment system with a dosing hopper featuring a viewing window to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a sewage tank dosing hopper with a viewing window, in order to solve the problem mentioned in the background art that the fixed position of the dosing hopper in the sewage tank with a viewing window easily leads to drug clumping.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a sewage tank dosing hopper with a viewing window, including a tank body, an inlet pipe and an outlet pipe respectively provided on both sides of the tank body, and an observation window provided on the side wall of the tank body, the observation window being made of transparent material;

[0006] A fixed plate is located at the center of the top of the tank. A fixed shell is located at the top of the tank. The bottom of the fixed shell is connected to the top of the fixed plate. A rotating rod is rotatably located at the center of the fixed plate. A stirring blade is located at the bottom of the rotating rod. A drive gear is mounted on the rotating rod. A rotating shaft is rotatably located at the bottom of the fixed plate. A driven gear that meshes with the drive gear is mounted on the rotating shaft. An internal meshing gear that meshes with the driven gear is located inside the tank. The internal meshing gear is slidably connected to the inside of the tank. A medicine outlet hopper is mounted on the internal meshing gear. A medicine inlet hopper is located at the top of the medicine outlet hopper. A stop is located inside the medicine outlet hopper. A moving rod slides through the inside of the medicine outlet hopper. The top of the medicine outlet hopper is connected to the moving rod via a lifting assembly.

[0007] A further improvement is that a rotating baffle is provided on the top of the tank, and the rotating baffle is fixedly connected to the medicine dispensing hopper.

[0008] A further improvement is that multiple sets of limiting blocks are slidably provided inside the tank, and all sets of limiting blocks are connected to the side wall of the rotating baffle.

[0009] A further improvement is that the lifting assembly includes a movable trough and a lead screw. The top of the medicine hopper is provided with a movable trough, the lead screw is rotatably provided inside the movable trough, and a slider is slidably provided inside the movable trough. The slider is threadedly connected to the lead screw, and the bottom of the slider is connected to the top of the movable rod.

[0010] A further improvement is that: the tank body is provided with a limiting groove, and multiple sets of limiting rods are slidably arranged inside the limiting groove, with the top of each set of limiting rods connected to the bottom of the internal meshing gear.

[0011] A further improvement is that: the bottom of the medicine dispensing hopper is provided with a medicine dispensing pipe, the stop block is conical in shape, and the diameter of the stop block is the same as the diameter of the medicine dispensing pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When using the sewage tank dosing hopper with a viewing window, the lifting component drives the moving rod to slide inside the dosing hopper, causing the moving rod to drive the stop block to rise. This creates a gap between the stop block and the inner wall of the dosing hopper, allowing the medicine to be dispensed. The higher the stop block is, the larger the gap between it and the inner wall of the dosing hopper, and the faster the dosing speed. At the same time, when in use, the motor drives the rotating rod to rotate. Through the interaction between the drive gear, the rotating shaft, and the internal meshing gear, the internal meshing gear drives the position of the dosing hopper to change. By distributing the medicine at multiple positions, excessive concentration of the medicine in a local area is avoided. Combined with flow regulation, a gradient distribution of the dosage is achieved, allowing the medicine to fully contact and react with the sewage, reducing the risk of clumping.

The drive gear 9 and the fixed disk 5 are rotatably provided with a rotating shaft 10. The rotating shaft 10 is equipped with a driven gear 11 that meshes with the drive gear 9. The tank body 1 is provided with an internal meshing gear 12 that meshes with the driven gear 11. The internal meshing gear 12 is slidably connected to the inside of the tank body 1. The internal meshing gear 12 is equipped with a medicine dispensing hopper 13. The tank body 1 is provided with a limiting groove 21. Multiple sets of limiting rods 22 are slidably provided inside the limiting groove 21. The tops of the multiple sets of limiting rods 22 are all connected to the bottom of the internal meshing gear 12.

[0021] Simultaneously, the motor drives the rotating rod 7 to rotate, which in turn drives the bottom stirring blade 8 to rotate, allowing the medicine and liquid to mix. At the same time, the driving gear 9 above the rotating rod 7 drives the driven gear 11 to rotate through the rotating shaft 10. Then, the driven gear 11 drives the internal meshing gear 12 to rotate. The internal meshing gear 12 slides in the limiting groove 21 inside the tank 1 through multiple sets of limiting rods 22, causing the internal meshing gear 12 to rotate and drive the dispensing hopper 13 to rotate synchronously, changing the position of the dispensing hopper 13 and dispensing medicine into the tank 1 at different positions. The movement of the dispensing hopper 13 also drives the rotating baffle 18 to rotate synchronously inside the tank 1 through multiple sets of limiting blocks 19. The rotating baffle 18 prevents dust from entering the tank 1. After the mixing is completed, the medicine liquid is pumped out into the sewage tank through the liquid outlet pipe 3 in conjunction with the external liquid pump.

[0022] The top of the dispensing hopper 13 is provided with a feeding hopper 14. The inside of the dispensing hopper 13 is provided with a stop block 15. A moving rod 16 is slidably passed through the inside of the dispensing hopper 13. The top of the dispensing hopper 13 is connected to the moving rod 16 through a lifting assembly 17. The lifting assembly 17 includes a moving groove 171 and a lead screw 172. The top of the dispensing hopper 13 is provided with a moving groove 171. The lead screw 172 is rotatably provided inside the moving groove 171. A slider 20 is slidably provided inside the moving groove 171. The slider 20 is threadedly connected to the lead screw 172. The bottom of the slider 20 is connected to the top of the moving rod 16. The top of the tank body 1 is provided with a rotating baffle 18. The rotating baffle 18 is fixedly connected to the dispensing hopper 13. Multiple sets of limiting blocks 19 are slidably provided inside the tank body 1. All sets of limiting blocks 19 are connected to the side wall of the rotating baffle 18. The bottom of the dispensing hopper 13 is provided with a dispensing pipe 23. The stop block 15 is conical in shape, and the diameter of the stop block 15 is the same as the diameter of the dispensing pipe 23.

[0023] When using the sewage tank dosing hopper with a viewing window, the pre-prepared medicine is added into the dosing hopper 13 through the inlet hopper 14. At this time, the liquid inlet pipe 2 on the side wall of the tank 1 injects the external mixing liquid into the inside. Then, the screw 172 inside the movable trough 171 at the top of the dosing hopper 13 can be rotated by the motor. The screw 172 drives the slider 20 to move. The slider 20 drives the moving rod 16 to slide inside the dosing hopper 13. At this time, the moving rod 16 drives the stop 15 to rise inside the dosing hopper 13. After the stop 15 creates a gap with the inner wall of the dosing hopper 13, the medicine enters the dosing pipe 23 below to complete the dosing.

[0024] Working Principle: When using the wastewater tank dosing hopper with a viewing window, the pre-prepared medicine is added to the dosing hopper 13 through the inlet hopper 14. At this time, the liquid inlet pipe 2 on the side wall of the tank 1 injects the external mixing liquid into the interior. Then, the motor can start the screw 172 inside the moving trough 171 at the top of the dosing hopper 13 to rotate. The screw 172 drives the slider 20 to move, and the slider 20 drives the moving rod 16 to slide inside the dosing hopper 13. At this time, the moving rod 16 drives the stop 15 to rise inside the dosing hopper 13. After the stop 15 creates a gap with the inner wall of the dosing hopper 13, the medicine enters the dosing pipe 23 below to complete the dosing. At the same time, the motor drives the rotating rod 7 to rotate. At this time, the rotating rod 7 drives the bottom stirring blade 8 to rotate, so that the medicine and liquid are mixed. When the mixing is complete, the drive gear 9 above the rotating rod 7 drives the driven gear 11 to rotate through the rotating shaft 10. At this time, the driven gear 11 drives the internal meshing gear 12 to rotate. The internal meshing gear 12 slides in the limiting groove 21 inside the tank 1 through multiple sets of limiting rods 22, so that the rotation of the internal meshing gear 12 drives the medicine dispensing hopper 13 to rotate synchronously, so that the position of the medicine dispensing hopper 13 changes, and medicine is dispensed into the tank 1 at different positions. The movement of the medicine dispensing hopper 13 also drives the rotating baffle 18 to rotate synchronously inside the tank 1 through multiple sets of limiting blocks 19. The rotating baffle 18 prevents dust from entering the tank 1. After the mixing is completed, the medicine liquid is pumped out into the sewage tank through the liquid outlet pipe 3 in conjunction with the external liquid pump, thus completing a series of operations.
