[0025] In order to make the purpose of the invention, technical solutions and beneficial effects of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0026] like Figures 1 to 3 As shown, a flocculant automatic dispensing system includes a flocculant feeding mechanism 1, a dissolving tank 4, a feeding mechanism 2, a storage box, a detection system 7 and a control system;

[0027] The flocculant feeding mechanism 1, the adding mechanism 2 and the storage tank are respectively connected to the dissolving tank 4, and the control system is respectively connected to the flocculant feeding mechanism 1 and the adding mechanism 2. The control system controls the flocculant feeding mechanism 1 to prepare flocculant and feeds the prepared flocculant into the dissolving tank 4. In the dissolving tank 4, the flocculant is added to the dissolving tank 4 through the adding mechanism 2, and the prepared flocculant is stored in the storage tank.

[0028] The utility model integrates preparation, storage and dosing in one, can detect the concentration of the liquid medicine in real time through the detection system 7, and control the amount of medicine added according to the required concentration of the liquid medicine through the control system, automatically stir, dissolve and mature the flocculant, and then add it to the treated water through the dosing pump, which greatly reduces the complexity of the flocculant use process, makes the dosing process automatic and accurate, and saves the amount of medicine.

[0029] In some embodiments of the present invention, the flocculant feeding mechanism 1 includes a preparation container, a first stirrer 3, a powdered agent storage tank and a spiral;

[0030] The preparation container is also connected to a water inlet pipeline 5 and a medicine transfer pipeline;

[0031] The external water source is connected to the preparation container through the water inlet pipe 5, and the powdered medicine storage tank is connected to the preparation container through the medicine transfer pipe;

[0032] The first stirrer 3 is placed above the preparation container to stir the powdered medicine and water, and after stirring, the flocculant is transported to the dissolution tank 4 through the screw.

[0033] In the present invention, by connecting the external water source and the preparation container through the water inlet pipe 5, and connecting the powdered medicine storage tank and the preparation container through the medicine transfer pipe, a fast and accurate input of the water source and the medicine is achieved. In addition, the first agitator 3 is placed above the preparation container, which can efficiently mix the powdered medicine with water, ensuring that the medicine can be quickly and evenly dissolved in the water to form the required flocculant. Through the coordination of the pipeline and the agitator, the medicine and water can be automatically added and mixed, reducing the tediousness and errors of manual operation. At the same time, the continuous delivery of the flocculant is achieved under the action of the spiral, ensuring that the flocculant of stable quality can be continuously obtained in the dissolution barrel 4. At the same time, since the manual operation links are reduced, the production cost and labor cost are also reduced. In addition, the accuracy of the use of the medicine can be ensured through precise pipeline connection and metering system.

[0034] In some embodiments of the present invention, a first stop valve and a first solenoid valve are provided in series on the water inlet pipeline 5; a second stop valve, a second solenoid valve and a third solenoid valve are provided on the transfer agent pipeline, and the second stop valve and the second solenoid valve are connected in series, and the second stop valve and the second solenoid valve connected in series are connected in parallel with the third solenoid valve.

[0035] Specifically, the first shutoff valve, a manual or mechanical valve, can be manually closed to shut off the water supply when needed. Furthermore, the first solenoid valve, an electrically operated valve, can be remotely opened and closed by the control system, achieving automated control. Using both valves in tandem provides dual control, ensuring rapid water shutoff in the event of a system anomaly or emergency shutdown.

[0036] In some embodiments of the present invention, the detection system 7 includes a plurality of liquid level gauges, temperature sensors and timers.

[0037] In detail, in the present invention, the detection system 7 is integrated with the automation system to realize automatic monitoring and control of liquid level and temperature, which helps to reduce manual intervention, improve work efficiency, and reduce operating costs.

[0039] In the present invention, various parameters required can be set by adding buttons of the TD400C text display; the time for the auger to add powder will be automatically calculated according to the set solution concentration by PLC6.

[0040] Once the control system is running automatically, under the control of PLC6, water addition, stirring, powder dosing, and liquid level detection are all automatically performed in the dissolution tank 4 according to the pre-set program. After the set dissolution time, the required drug solution is prepared and automatically transferred to the storage tank, and the flocculant dissolution preparation begins the next cycle. The flocculant solution in the storage tank is automatically and remotely transported to the flocculation tank by the dosing pump.

[0041] Furthermore, the utility model can achieve the effect of automatically adjusting the flow of the dosing pump according to the flow of the flow meter in the remote control mode, and the effect of automatically carrying out the entire process of preparation and delivery of the medicine under the control of PLC6.
