Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a dosing device for phosphorus removal in sedimentation tanks. Background Technology

[0002] A sedimentation tank is a structure that removes suspended solids from water through sedimentation, thus purifying the water. It utilizes the natural sedimentation or coagulation process to remove suspended solids. Sedimentation tanks are classified into horizontal and vertical sedimentation tanks based on the direction of water flow. The sedimentation effect depends on the water flow velocity and residence time within the tank. To improve sedimentation efficiency and reduce land area requirements, honeycomb inclined tube countercurrent flow sedimentation tanks, accelerated clarification tanks, and pulse clarification tanks are commonly used. Sedimentation tanks are widely used in wastewater treatment.

[0003] Chinese patent document CN111847617A discloses an intelligent control system for phosphorus removal dosing. The feedforward control system includes a first online total phosphorus detector and a first flow meter. The input ends of the first online total phosphorus detector and the first flow meter extend into the wastewater, and their output ends are connected to a PLC controller and an online learning control system. The online learning system consists of hardware and software components. The hardware component is an ARM development board, and the input ends of the ARM development board are connected from left to right to the feedforward control system, a third flow meter, a second flow meter, and the second online total phosphorus detector. This patent document combines an online learning model based on deep learning algorithms with a feedforward phosphorus removal control system, solving the problems of nonlinearity, time-varying characteristics, and time delay inherent in traditional phosphorus removal dosing control systems. It effectively meets production needs, demonstrating strong feasibility and practicality, and can reduce the dosage while ensuring stable effluent quality.

[0004] The aforementioned patent literature can reduce the dosage while ensuring stable effluent quality during implementation. However, it cannot monitor the dosage, which can lead to excessive or insufficient dosage, affecting the phosphorus removal effect of wastewater. Utility Model Content

A limiting mechanism 10 is fixedly connected to the upper outer side of the storage component 4, which can lock and limit the position of the bearing mechanism 7.

[0024] For the purpose of storing phosphorus removal agents, please refer to... Figure 2 The drug storage component 4 includes a drug storage tank 41. A solenoid valve 42 is installed and fixed in the lower part of the inner cavity of the drug storage tank 41, which can facilitate the direct discharge of the drug from the inner cavity of the drug storage tank 41 into the sewage treatment pond.

[0025] To achieve the purpose of supporting and fixing the drug storage assembly 4, refer to Figure 2 The support mechanism 5 includes a protective shell 51. Several support legs 52 are fixedly connected to the outer surface of the protective shell 51 in a ring array, which can support the medicine storage tank 41. The lower ends of the outer surfaces of the several support legs 52 are fixedly connected to the upper end of the outer surface of the mounting plate 1.

[0026] To achieve the purpose of detecting the volume of the drug added into the drug storage component 4, please refer to... Figure 2 The monitoring component 6 includes a fixed base 61. Several liquid level sensors 62 are installed and fixed at intervals on the right side of the outer surface of the fixed base 61, which can measure the dosage of the medicine put into the inner cavity of the medicine storage tank 41. The left side of the outer surface of the fixed base 61 is fixedly connected to the left wall of the inner cavity of the medicine storage tank 41.

[0027] To achieve the purpose of supporting the micro motor 8 and the stirring mechanism 9, refer to... Figure 3The supporting mechanism 7 includes a cover plate 71. Handles 72 are symmetrically fixedly connected to the left and right sides of the outer surface of the cover plate 71. Several arc-shaped plates 73 are fixedly connected in a ring array on the lower outer side of the outer surface of the cover plate 71. This can fix the position of the cover plate 71 after it is clamped in the limiting cavity opened on the outer surface of the corresponding limiting frame 102. The micro motor 8 is installed and fixed in the middle of the upper end of the cover plate 71.

[0028] To achieve the purpose of mixing and stirring the various agents placed inside the drug storage component 4, please refer to... Figure 3 The stirring mechanism 9 includes a rotating shaft 91, and several stirring plates 92 are fixedly connected to the outer surface of the rotating shaft 91 at intervals. It can stir the various mixed phosphorus removal agents in the inner cavity of the storage tank 41.

The specific installation method, circuit connection method and control method of the micro motor 8, solenoid valve 42 and liquid level sensor 62 are all conventional designs, and this utility model will not describe them in detail.

[0031] The working principle of this utility model is as follows: First, the mounting plate 1 is installed and fixed at the water inlet of the corresponding sewage treatment tank by several fastening screws 3. Then, when the agent for phosphorus removal in sewage is added into the inner cavity of the storage tank 41, the dosage of the agent injected into the inner cavity of the storage tank 41 can be detected by several liquid level sensors 62. After adding multiple agents into the inner cavity of the storage tank 41, the cover plate 71 is placed on the upper end of the storage tank 41 by holding two handles 72. During this process, several arc-shaped plates 73 are clamped in the inner cavity of the limiting frame 102. Thus, the cover plate 71 can be clamped and limited by the limiting cavity opened on the outer surface of the limiting frame 102 through the several arc-shaped plates 73. Then, the micro motor 8 is driven to drive the rotating shaft 91 and several sets of stirring plates 92 to rotate, so as to mix and stir the agent in the inner cavity of the storage tank 41. After the agent is stirred, the solenoid valve 42 is opened to allow the agent to flow along the inner wall of the storage tank 41 into the sewage treatment tank.
