Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a PAC intelligent high-speed mixing ratio dosing integrated machine. Background Technique

[0002] The existing PAC dosing device consists of a drug dissolving tank, a drug storage tank, a stirrer, a metering pump, a water level gauge, pipeline valves, and a control cabinet, and can be connected to a host computer for remote control. When the sewage treatment station operates, the dosing pump starts dosing according to the set value, and the liquid level in the drug storage tank continuously decreases. When the liquid level in the drug storage tank is lower than the set value, the liquid medicine in the drug dissolving tank is poured into the drug storage tank. The staff adds a certain amount of water and PAC medicine into the drug dissolving tank according to the water quality of the sewage treatment station to continue preparing new liquid medicine for standby.

[0003] The drug dissolving tank uses a stirrer to prepare liquid medicine. When the dosage of the medicine is large, it is easy to form lumps, and the drug dissolving time is relatively long. It is necessary to prepare the liquid medicine in advance to ensure that the tank is full for standby; when the water quality parameters change, it is necessary to manually adjust the mixing ratio concentration and dosing amount of the liquid medicine, and the adjustment is not timely and accurate. These ultimately affect the sewage treatment effect, and the long-term non-scientific use of medicine also causes the cost of the enterprise to rise. Content of the Utility Model

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] As Figure 1 shown, the present invention provides a PAC intelligent high-speed mixing and dosing integrated machine, which includes:

[0027] A medicine storage tank 1, which stores PAC powder, and a first stirring mechanism 2 and a weighing sensor 3 are arranged in the medicine storage tank;

[0028] A variable-frequency screw powder feeder 4, which is arranged in the medicine storage tank 1;

[0029] A dilution tank 5, at the inlet of which a high-speed mixer 6 is arranged, and the high-speed mixer 6 is connected to the output end of the variable-frequency screw powder feeder 4;

[0030] A water supply pipeline 7, the output end of which is connected to the high-speed mixer 6, and a variable-frequency water pump 8, a first valve 9 and a first electromagnetic flowmeter 10 are arranged on the water supply pipeline 7;

[0031] A medicine storage tank 11, which is communicated with the dilution tank 5 through a medicine delivery pipeline 12, and a second stirring mechanism 13 is arranged in the medicine storage tank 11, and a second valve 14 and a dumping pump 15 are arranged on the medicine delivery pipeline 12;

[0032] An ultrasonic sensor, which is arranged in the medicine storage tank 11 and detects the liquid level value of the liquid medicine therein, and the ultrasonic sensor is electrically connected to the first stirring mechanism 2, the variable-frequency screw powder feeder 4 and the second stirring mechanism 13;

[0033] and a chemical addition pipeline 16, which is arranged at the outlet of the chemical storage tank 11, and a third valve 17, a variable-frequency screw pump 18, a check valve 19 and a second electromagnetic flowmeter 20 are arranged on the chemical addition pipeline 16.

[0034] In an embodiment of the PAC intelligent high-speed mixing and proportioning chemical addition integrated machine provided by the present invention, it further includes a controller 20;

[0035] The controller 20 is electrically connected to the variable-frequency screw pump 18, the variable-frequency screw powder feeder 4 and the variable-frequency water pump 8;

[0036] The controller 20 is electrically connected to the ultrasonic sensor.

[0037] In an embodiment of the PAC intelligent high-speed mixing and proportioning chemical addition integrated machine provided by the present invention, the third valve 17, the variable-frequency screw pump 18 and the check valve 19 are arranged in two groups in parallel.

[0038] In an embodiment of the PAC intelligent high-speed mixing and proportioning chemical addition integrated machine provided by the present invention, it further includes a sewage influent water quality detection sensor and a sewage effluent water quality detection sensor after purification, and the sewage influent water quality detection sensor and the sewage effluent water quality detection sensor after purification are electrically connected to the controller 20.

[0039] During the operation of the sewage treatment station, data such as sewage influent water quality parameters, sewage effluent water quality parameters after purification, and sewage influent flowmeter are input into the controller. After the controller calculates the optimal chemical addition concentration and chemical addition amount, it outputs a control signal, and the variable-frequency screw pump operates to add chemicals according to the given frequency. When the ultrasonic sensor of the chemical storage tank detects that the material level of the chemical storage tank is at a low level, the stirring motor in the chemical storage tank automatically operates. According to the chemical addition concentration and flow rate, the controller controls the variable-frequency screw powder feeder to feed powder at a given frequency and the variable-frequency water pump to supply water at a given frequency. The powder and water in the chemical storage tank enter the high-speed mixer in proportion and are mixed evenly and then enter the dilution tank. The dumping pump automatically transports the chemical liquid in the dilution tank to the chemical storage tank. When the liquid level of the chemical storage tank is at a high level, the chemical preparation stops.

[0040] The PAC intelligent high-speed hybrid dosing machine adopts a modular design. By modeling the historical operation data of the sewage treatment station, the control system can adjust the optimal chemical dosing concentration and dosing amount in real time according to the sewage quality parameters and flow rate changes. Precise powder feeding and water supply are achieved by controlling the variable-frequency screw powder feeder, weighing sensor, variable-frequency water pump, electromagnetic flowmeter, and electric valve, so as to make the concentration of the prepared liquid medicine accurate. The medicine powder and water are quickly mixed evenly by the high-speed mixer and then stored in the dilution tank for immediate use, which shortens the preparation time of the liquid medicine and prevents the formation of lumps due to uneven stirring and dissolution. Precise dosing of sewage is achieved by the variable-frequency screw pump and electromagnetic flowmeter. The data collection and interaction use Ethernet, Modbus-TCP, and RS-485 communication protocols, and interlocks are implemented in each control link to achieve unattended and fully automatic precise dosing.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
