However, the existing adding devices cannot accurately control the amount of water treatment agents injected into the sewage treatment during use. When the amount of water treatment agents injected is too much, it will cause waste. When the amount of water treatment agents injected is too little, the treatment effect of the sewage cannot be guaranteed. In response to the above problems, a water treatment agent adding device for sewage treatment is proposed. Utility Model Content

A quantitative addition mechanism 4 is fixedly installed at the bottom of the filter mechanism 3. The filter mechanism 3 includes a filter tank 31, a motor 34, a conical filter screen 35, a drive rod 36, a bevel gear 38 and a bevel gear ring 310.

[0026] The effect achieved by the entire embodiment is that by setting the filtering mechanism 3, after the device has been used for a period of time, the controller 2 is used to turn on the motor 34, and the motor 34 drives the driving rod 36 and the bevel gear 38 to rotate. The outer wall of the bevel gear 38 is engaged with the outer wall of the bevel gear ring 310, so that the bevel gear ring 310 can be driven to rotate on the top of the retaining ring 311, and the bevel gear ring 310 drives the scraper 39 to slide on the surface of the conical filter screen 35.

[0027] The method of use and working principle of this device: When using the device, first add an appropriate amount of water treatment agent to the filter tank 31 through the feeding pipe 33. The water treatment agent is filtered through the conical filter 35 and reaches the bottom of the filter tank 31. The conical filter 35 can filter out large particles in the water treatment agent to prevent large particles from accumulating at the bottom of the filter tank 31 and causing pipe blockage. A transparent plate and scale lines are provided on the front side of the filter tank 31 to facilitate staff to observe the remaining water treatment agent in the filter tank 31. When the remaining water treatment agent is insufficient, it is convenient for staff to add water treatment agent to the filter tank 31 in time.

[0028] According to the amount of water treatment agent added to the sewage as needed, the staff can adjust the valve opening size of the quantitative valve 45 through the controller 2 to achieve the required water treatment agent flow rate.

The amount of water treatment agent is adjusted to achieve quantitative addition of water treatment agent). When the feed solenoid valve 46 opens at the set time, the water treatment agent in the filter tank 31 is discharged into the addition tank 41 through the connecting pipe 42. When the set time is reached, the feed solenoid valve 46 closes and the water treatment agent is quantitatively added to the addition tank 41. When the discharge solenoid valve 44 opens at the set time, the water treatment agent in the addition tank 41 is quantitatively added to the sewage, thereby achieving quantitative addition of water treatment agent, avoiding waste of water treatment agent, or affecting the sewage treatment effect due to insufficient amount of water treatment agent added, and being able to complete the addition of water treatment agent on a timely and quantitative basis.

[0029] At the same time, by setting the filtering mechanism 3, after the device has been used for a period of time, the controller 2 is used to turn on the motor 34, and the motor 34 drives the driving rod 36 and the bevel gear 38 to rotate. The outer wall of the bevel gear 38 is engaged with the outer wall of the bevel gear ring 310, so that the bevel gear ring 310 can be driven to rotate on the top of the retaining ring 311, and the bevel gear ring 310 drives the scraper 39 to slide on the surface of the conical filter screen 35. The scraper 39 can scrape the particles on the outer surface of the conical filter screen 35 downwards, and the particles slide along the conical filter screen 35 to between the retaining ring 311 and the fixing ring 37, so as to quickly process the particles on the conical filter screen 35, avoid the mesh clogging of the conical filter screen 35 after long-term use and affect the filtering effect, and ensure the normal use of the conical filter screen 35 and the filtering effect of the water treatment agent.
