Description

Technical Field

[0001] This utility model relates to the field of throwing devices, and in particular to a wastewater pool flocculant throwing device. Background Technology

[0002] With the acceleration of industrialization and urbanization, the amount of sewage discharge is increasing day by day. Sewage treatment has become a key link in protecting the environment and ensuring the sustainable use of water resources. In the sewage treatment process, adding flocculants to sewage ponds is a core process. Its role is to cause suspended particles, colloids and other impurities in sewage to agglomerate into larger flocs, which are then removed by subsequent sedimentation, filtration and other means, thereby effectively reducing the concentration of pollutants in sewage and improving water quality.

[0003] Wastewater treatment ponds of different sizes and for different purposes exhibit significant differences in structure and operational characteristics. Some large industrial wastewater treatment ponds have vast areas and considerable depths, with complex flow patterns within the ponds and varying pollutant concentrations and distributions in different areas. In contrast, small urban domestic wastewater treatment ponds may have unique shapes and flow characteristics due to factors such as the surrounding environment and treatment scale. Existing flocculant dosing devices for wastewater treatment ponds mostly have fixed nozzle positions or can only be adjusted to a very limited extent. This makes it impossible to flexibly adjust the flocculant dosing position according to the actual situation when dealing with different wastewater treatment ponds.

[0004] Therefore, in order to address this problem, this utility model provides a flocculant throwing device for sewage tanks. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a flocculant throwing device for sewage tanks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sewage tank flocculant dispensing device, comprising a fixed tank body, an annular adjusting seat at the bottom of the fixed tank body, an annular adjusting frame connected to the inner wall of the annular adjusting seat by a thread, a first adjusting rod at the top of the annular adjusting frame, a first sliding seat slidably connected to the surface of the first adjusting rod, a first limiting member connected to the surface of the first adjusting rod by a thread, the first limiting member being located below the first sliding seat, a second adjusting rod at the top of the first sliding seat, a second sliding seat slidably connected to the surface of the second adjusting rod, a second limiting member connected to the surface of the second adjusting rod by a thread, the second limiting member being located below the second sliding seat, a third adjusting rod at the top of the second sliding seat, and a nozzle assembly detachably mounted on the top of the third adjusting rod by a thread, the nozzle assembly being connected to the fixed tank body by a pipe.

[0007] Preferably, a drive motor is provided at the bottom of the fixed barrel, and a stirring frame is fixedly connected to the output end of the drive motor through the fixed barrel. Stirring blades are sleeved on the surface of the stirring frame.

[0008] Preferably, the top of the stirring frame is connected to a fixing sleeve by a thread, and the fixing sleeve is located above the stirring blades.

[0009] Preferably, the annular adjusting frame is provided with a sliding rod on the side near the second adjusting rod, and the sliding rod is slidably connected to the second adjusting rod.

[0010] Preferably, a support frame is provided at the bottom of the fixed barrel body for supporting its use.

[0011] Preferably, the nozzle assembly includes a nozzle frame, and a fixed nozzle is provided at one end of the nozzle frame.

[0012] Compared with the prior art, the present invention provides a wastewater tank flocculant dosing device, which has the following beneficial effects:

[0013] 1. This wastewater treatment tank flocculant dosing device, through its unique structural design, enables flexible and precise adjustment of the nozzle assembly position. Utilizing a threaded connection between a ring-shaped adjusting frame and a ring-shaped adjusting seat, along with first and second adjusting rods and corresponding sliding seats and limiting components, the nozzle assembly position can be adjusted in both horizontal and vertical directions. Vertically, rotating the first and second limiting components precisely controls the height of the first and second sliding seats, changing the dosing height. Horizontally, adjusting the threaded position of the ring-shaped adjusting frame within the ring-shaped adjusting seat changes the horizontal position of the nozzle assembly. The sliding connection between the sliding rod and the second adjusting rod enhances adjustment stability and ensures accurate position adjustment. This function allows the device to adjust the flocculant dosing position according to the actual conditions of different wastewater tanks, such as tank size and wastewater distribution, promoting more uniform distribution in the wastewater, improving flocculation effect and wastewater treatment capacity, and adapting to various complex working conditions.

[0014] 2. This wastewater tank flocculant throwing device uses a drive motor to rotate the stirring frame and stirring blades, which fully stirs the flocculant in the fixed tank. The arc design of the stirring blades and the reasonable installation method can effectively improve the stirring efficiency, so that the components of the flocculant are fully and evenly mixed, avoiding sedimentation or stratification, ensuring that the quality of the thrown flocculant is stable and has good flocculation performance.
