Description

Technical Field

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

[0002] With the rapid development of industrialization and urbanization, wastewater treatment has become an important part of environmental protection. In current wastewater treatment processes, the chemical dosing tank, as a key component, is mainly used to mix chemical agents with wastewater for treatment.

[0003] When wastewater treatment chemicals are added to the wastewater, they are usually introduced from the top. Under current technology, due to uneven mixing or poor fluid dynamics, some sediments tend to float to the surface with bubbles or other physical effects instead of settling to the bottom as expected. This not only affects the effectiveness of the chemicals in treating pollutants but may also lead to substandard effluent quality, increasing the burden on subsequent treatment processes. Secondly, existing wastewater treatment systems lack effective sedimentation and sludge removal mechanisms. If the sediments formed under the action of chemicals are not separated and removed from the water in a timely and effective manner, they will accumulate inside the system, occupying treatment space and reducing the overall system efficiency. In the long run, this will also increase maintenance costs and may cause secondary pollution problems. Utility Model Content

[0004] In view of the problems mentioned in the background art above, the present invention provides a wastewater treatment agent dosing tank.

[0005] The technical solution adopted by this utility model is as follows: A wastewater treatment agent dosing tank includes a mounting frame, a stirring assembly, and a dispensing box. A first treatment tank and a second treatment tank are arranged on the mounting frame. A wastewater inlet pipe is provided at the top of the first treatment tank, and a wastewater outlet pipe is provided at the top of the second treatment tank. A connecting pipe is provided between the first treatment tank and the second treatment tank. The first treatment tank and the second treatment tank have the same structure. The first treatment tank includes an outer tank box and an inner cylinder arranged in the outer tank box. A connecting plate is provided at the top of the inner cylinder, which is connected to the outer tank box. The inner cylinder is open at both the top and bottom. The wastewater inlet pipe is located below the connecting plate, and the wastewater outlet pipe is located above the connecting plate. A filter screen is installed at the bottom of the inner cylinder of the second treatment tank. The stirring assembly is arranged inside the inner cylinder of the first treatment tank. The dispensing box is installed on the top of the first treatment tank for dosing the agent.

[0006] Furthermore, one end of the connecting pipe is connected to the top of the first treatment pool connecting plate, and the other end is connected to the bottom of the second treatment pool connecting plate.

[0007] Furthermore, the stirring assembly includes a rotating column rotatably disposed at the top of the first treatment tank, and a plurality of stirring rods are disposed around the rotating column.

[0008] Furthermore, a drive motor is provided at the top of the first treatment pool, and the output shaft of the drive motor is connected to the rotating column.

[0009] Furthermore, the material discharge opening of the discharge box is located inside the inner cylinder of the first processing pool.

[0010] Furthermore, a sealing door is installed at the bottom of the first treatment pool.

[0011] Furthermore, both the first and second treatment tanks are equipped with drain pipes at the bottom.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a first treatment tank and a second treatment tank, and connecting them with a pipe, the wastewater can be further filtered and purified after initial mixing with chemicals, improving treatment efficiency and effluent quality. The design of the inner cylinder with openings at both ends, combined with the connecting plate connecting to the outer tank, allows the wastewater to form an effective flow path between the inner and outer cylinders, increasing the contact area and time between the chemicals and the wastewater, and improving reaction efficiency. At the same time, the filter screen installed at the bottom of the second treatment tank helps the sediment to settle more naturally, reducing floating phenomena. It can effectively intercept and collect the sediment flowing in from the first treatment tank, providing a simple sedimentation and sludge removal mechanism, avoiding the accumulation of sediment in the system, reducing maintenance costs, and preventing secondary pollution.
