Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and in particular relates to a water treatment dosing system. Background Art

[0002] Because water contains various mineral salts and gases, when the dissolved salts reach saturation during circulation, solid matter precipitates and forms deposits. If deposited on heated surfaces, this deposit forms scale, which not only clogs pipes but also affects heat transfer efficiency and increases metal corrosion, posing a safety hazard. Furthermore, existing dosing systems rarely address the operating conditions of cold northern regions, making it prone to incomplete dissolution of chemicals in the tanks, leading to deposits or scaling, which compromises the safety of the entire system. In actual water treatment processes, several chemicals are sometimes combined, with dosages adjusted based on water quality. Utility Model Content

DETAILED DESCRIPTION

[0016] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0017] like Figure 1As shown, the utility model provides a water treatment dosing system, including a medicine tank 7. Specifically, the medicine tank 7 can be set on a bracket. One side of the top of the medicine tank 7 is connected to the funnel 2 through a rotary feed valve 3. Generally, the medicine is a granular or powdered solid. The use of the rotary feed valve 3 can control the amount of medicine fed so that it can feed the medicine at a uniform and stable speed. Specifically, a dosing cover 1 is provided on the top of the funnel 2. The dosing cover 1 is opened when the operator adds medicine and closed after the dosing is completed to prevent debris from falling into the funnel 2, affecting the purity of the medicine solution or causing damage to the rotary feed valve 3. Specifically, a scale is provided inside the funnel 2, and the medicine can be added to a certain amount according to the scale, matching the amount of water automatically added, to the most suitable concentration, which is convenient for the operator to pour the medicine quantitatively; when mixing and dosing, the appropriate amount of medicine can be added according to the scale.

[0018] The other side of the top of the medicine tank 7 is connected to the instantaneous heater 6 through the water inlet electric valve 17 and the pipeline. The instantaneous heater 6 is connected to the water inlet. In the cold northern regions, the temperature is low in winter, and the temperature of the purified water for dissolving the medicine is not high, which is not the optimal dissolution temperature. By providing the instantaneous heater 6, the water temperature entering the medicine tank 7 can be timely increased, the dissolution speed is accelerated, the dissolution efficiency is improved, and the solubility can be increased, the use time of the medicine solution is extended, and the workload of the staff is reduced.

[0019] A liquid level gauge 5 is provided in the medicine tank 7 to monitor the volume of the medicine liquid in the medicine tank 7 in real time. A liquid level sensor is provided on the liquid level gauge 5 to alarm when the liquid level is low to remind the staff that the medicine liquid is insufficient. Preferably, the liquid level gauge 5 is a flap level gauge.

[0020] The medicine tank 7 is provided with a stirring device for stirring the medicine and accelerating the dissolution rate of the medicine. The stirring device includes a stirring part and a power part. The stirring part can be a stirring paddle and the power part can be a stirring pump 9. The stirring pump 9 can be arranged at the bottom of the medicine tank 7. The lower part of the medicine tank 7 is provided with a medicine liquid outlet 12. The medicine liquid outlet 12 is connected to the production water pipe 14 through a pipeline and a dosing pump 15. The dosing pump 15 can be arranged on a bracket. The medicine liquid is added to the production water pipe 14 through the medicine liquid outlet 12 and the dosing pump 15 to add medicine to the production water pipe 14. Specifically, a safety filter 16 is provided on the pipeline connecting the medicine liquid outlet 12 and the dosing pump 15 to prevent large particles of solid matter from entering the dosing pump 15 and damaging the dosing pump 15.

[0021] The production water pipe 14 is provided with an online water quality detector 13. Specifically, the online water quality detector 13 is located downstream of the connection between the production water pipe 14 and the dosing pipeline. The rotary feed valve 3, liquid level meter 5, instantaneous heater 6, power device of the stirring device, online water quality detector 13, dosing pump 15, water inlet electric valve 17 are electrically connected to the integrated control cabinet 10. The integrated control cabinet 10 controls the start and stop of the rotary feed valve 13, dosing pump 15, stirring pump 9, instantaneous heater 6, and water inlet electric valve. The integrated control cabinet 10 can also be set with emergency full stop, automatic / manual, and one-button start functions. The control part of the integrated control cabinet 10 is existing technology and will not be repeated here. The online water quality detector 13 monitors the dosing situation online in real time and returns the monitoring results to the integrated control cabinet 10. The integrated control cabinet 10 controls the dosing frequency of the dosing pump 15, thereby adjusting the dosing amount and controlling the concentration of the liquid medicine in the production water pipe 14. The integrated control cabinet 10 can be set on a bracket.

[0022] The medicine tank 7 is provided with an overflow port 4 at the top and a drain port 8 at the bottom. The overflow port 4 and drain port 8 are connected by a three-way pipe, and the third channel drains into the ditch. When the liquid in the medicine tank 7 continues to rise, it can be directly discharged into the ditch through the overflow port 4, preventing the pressure in the medicine tank from increasing and damaging the system. Specifically, a staircase 11 is provided on one side of the funnel 2 to facilitate staff to add medicine.

[0023] Example 1

[0024] When the liquid level is low and the automatic / manual control on the integrated control box 10 is in automatic control, the workflow is as follows:

[0025] When the liquid in the medicine tank 7 is insufficient, the sensor on the liquid level gauge 5 senses this and issues a low-level alarm. The water inlet electric door 17 starts to fill the medicine tank 7, and then the instantaneous heater 6 starts to heat the incoming water. When a certain amount of water is filled, the instantaneous heater 6 stops heating, and after a set time interval, the water inlet electric door 17 stops filling water to prevent overheating. At the same time, the stirring pump 9 starts working. After hearing the alarm, the staff reaches the corresponding height via the stairs 11, opens the dosing cover 1, and pours a certain amount of solid medicine into the funnel 2 according to the scale line inside the funnel 2, and then covers the dosing cover 1. The rotary feed valve 3 is started, and after the dosing is completed, the rotary feed valve 3 is stopped to complete the dosing process. When the online water quality detector 13 detects a low concentration of medicine in the production water pipe 14, the dosing pump 15 increases its frequency. When the online water quality detector 13 detects a high concentration of medicine in the production water pipe 14, the dosing pump 15 decreases its frequency, thereby maintaining stable operation of the system.

[0026] When the staff finds that the system has a fault or other unexpected situation, they can initiate an emergency stop and the system will stop working completely.

[0027] Example 2

[0028] When the liquid level is low and the automatic / manual control on the integrated control box 10 is in manual control, the workflow is as follows:

[0029] When the liquid in the medicine tank 7 is insufficient, the sensor on the liquid level meter 5 senses it and issues a low-level alarm. The staff then activates the electric water inlet door 17, which starts to inject water into the medicine tank 7. The instant heater 6 then starts to heat the incoming water. At this point, the staff can reach the corresponding height via the stairs 11, open the dosing cover 1, and pour a certain amount of solid medicine into the funnel 2 according to the scale line in the funnel 2. The staff then closes the dosing cover 1. The staff also activates the rotary feed valve 3 and the stirring pump 9, which starts working. After the dosing is complete, the rotary feed valve 3 is stopped, completing the dosing process. When a certain amount of water is injected, the instant heater 6 stops heating. After a set time interval, the electric water inlet door 17 stops injecting water again to prevent overheating. After the medicine is completely dissolved, the stirring pump start / stop button is pressed to stop the stirring pump 9. Start the stirring pump 9. When the online water quality detector 13 detects that the drug concentration in the production water pipe 14 is low, the dosing pump 15 increases the frequency. When the online water quality detector 13 detects that the drug concentration in the production water pipe 14 is high, the dosing pump 15 reduces the frequency, thereby maintaining stable operation of the system.

[0030] When the staff finds that the system has a fault or other unexpected situation, they can initiate an emergency stop and the system will stop working completely.
