[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] To address the problem that existing dry powder dosing devices struggle to grind agglomerated dry powder, potentially causing blockages during dosing, the following solution is disclosed. Please refer to [link / reference]. Figures 1-5 This utility model provides a technical solution: a modular dry powder dosing device for sewage treatment, including a device body 1 and a control box 2 electrically connected to the outside of the device body 1;

[0033] The main body 1 of the device is equipped with a grinding mechanism, which includes a first drive shaft 7 and a grinding roller 8 connected to the top of the first drive shaft 7. The main body 1 of the device is equipped with a screen 16, and the grinding roller 8 is attached to the top of the screen 16. The first drive shaft 7 is equipped with a scraper 9 in the middle and a turbine blade 10 is installed at the bottom of the first drive shaft 7.

[0034] The device body 1 is equipped with a drive mechanism at the top, and the bottom of the drive mechanism is connected to the grinding mechanism. The device body 1 is also equipped with a discharge pipe 11 at the bottom.

[0035] The top of the main body 1 is fixedly connected to the drive mechanism, and the drive mechanism includes a drive motor 4. A first sprocket 5 is installed at the bottom of the drive motor 4. A chain is engaged on the outside of the first sprocket 5, and a second sprocket 6 is engaged at the other end of the chain.

[0036] The bottom of the second sprocket 6 is fixedly connected to the first drive shaft 7, and the second sprocket 6 is rotatably connected to the main body 1 of the device through a bearing seat. The bottom of the first sprocket 5 is provided with a second drive shaft 13, and the bottom of the second drive shaft 13 is provided with a bevel gear set 14. The left end of the bevel gear set 14 is connected to an auger shaft 15.

[0037] The auger shaft 15 is located inside the discharge pipe 11, and the top of the discharge pipe 11 is connected to the internal pipe of the device body 1. The device body 1 is provided with an anti-scratching wall 3, which is in contact with the scraper 9. The top of the device body 1 is equipped with a feed pipe 12, and the bottom of the first drive shaft 7 is rotatably connected to the inside of the device body 1. The bottom of the device body 1 is provided with feet, and the device body 1 is fixed by the feet. The control box 2 can connect multiple sets of device bodies 1 at the same time.

[0038] Working principle: When using this modular dry powder dosing device for wastewater treatment, first connect the power supply of the equipment to the power grid, then transfer the dry powder agent to the top of the main body 1 of the device. The drive mechanism is controlled by the control box 2, which drives the grinding mechanism to run. This causes the grinding drum 8 to grind the dry powder in conjunction with the screen 16. The clumps of dry powder will fall into the main body 1 of the device under the grinding of the grinding drum 8 and the screen 16, so that the turbine blade 10 can transfer the dry powder to the discharge pipe 11.

[0039] When the drive mechanism is running, the drive motor 4 will drive the first sprocket 5 to rotate, which in turn drives the second sprocket 6 through the chain, which in turn drives the first drive shaft 7 to rotate. At the same time, the first sprocket 5 will also drive the second drive shaft 13 and the bevel gear set 14 to rotate, which in turn drives the auger shaft 15 to rotate, enabling the auger shaft 15 to add dry powder inside the discharge pipe 11.
