Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a precipitant dosing device for a wastewater treatment sedimentation tank. Background Technology
[0002] Solid wastewater treatment flocculants are chemicals used in water treatment processes, primarily to accelerate the sedimentation of particles in suspensions, thereby clarifying the solution and promoting filtration. These flocculants are typically high-molecular-weight polymers, such as polyacrylamide (PAM). They work by adsorbing suspended solid particles in water, bridging the particles or neutralizing their charges to form large flocs, thus accelerating the sedimentation of particles in the suspension. In wastewater treatment, flocculants need to be added, necessitating the use of a flocculant dosing device in a wastewater treatment sedimentation tank.
[0003] However, existing dosing devices have weak filtration capabilities. During the storage of the precipitant, it can be affected by the environment, resulting in partial clumping. Existing dosing devices struggle to filter out these clumped precipitants. When using the precipitant, clumped precipitant is added to the sedimentation tank along with unclumped precipitant, potentially affecting the wastewater sedimentation effect. Furthermore, smaller dosing devices have poor mixing performance. Adding a large amount of precipitant to the sedimentation tank at once can lead to incomplete dissolution and clumping. Clumped precipitant negatively impacts wastewater treatment efficiency, resulting in reduced treatment effectiveness. Utility Model Content
[0004] The purpose of this invention is to provide a precipitant dosing device for a wastewater treatment sedimentation tank, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

A sealing plate is fixedly connected to the bottom of the electric telescopic rod. A sealing gasket is fixedly connected to the bottom of the sealing plate.

[0013] 1. This utility model, through the arrangement of a storage tank, a sealing plate, a filter screen, and a rotating plate, allows for the addition of solid precipitant by opening the feed plate on the storage tank. Then, an external power supply sequentially activates the servo motor and electric telescopic rod within the fixed frame. The transmission rod on the servo motor drives the stirring plate to rotate, which, in conjunction with the connecting column and connecting rod, drives the rotating plate to rotate. The electric telescopic rod then moves the sealing gasket under the sealing plate upwards, allowing the precipitant in the storage tank to enter the filter frame. The rotating plate pushes the precipitant on the filter screen, and the filter screen intercepts any clumps in the precipitant, preventing clogging with the help of the rotating plate, thus improving the quality of the precipitant delivery.
[0014] 2. This utility model, through the setting of a mixing tank and a mixing plate, first adds an appropriate amount of water into the mixing tank through the water inlet pipe during use. Then, the servo motor in the fixed frame is started by an external power supply. The transmission rod on the servo motor drives the mixing plate to rotate, stirring the precipitant falling from the filter screen and the water, thereby making the precipitant and water mix evenly and achieving the effect of ensuring the quality of sewage sedimentation.
