[0020] Figure 2 This is a structural schematic diagram of another preferred embodiment of the dosing equipment provided by the utility model. DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0022] See Figure 1 The medicine mixer includes a medicine mixing barrel 1, a main pipe 2, a medicine dosing unit 3 and a medicine discharging unit 4. One end of the main pipe 2 is connected to the bottom of the medicine mixing barrel 1, and the other end of the main pipe 2 forms a closable sewage outlet 21. The medicine dosing unit 3 and the medicine discharging unit 4 are respectively connected to the main pipe 2. The medicine dosing unit 3 transports high-concentration medicine and clean water into the medicine mixing barrel 1 through the main pipe 2 to achieve the configuration of the medicine. The medicine discharging unit 4 can output the configured medicine to the outside through the main pipe 2. The medicine dosing unit 3 only transports clean water into the medicine mixing barrel 1, which can also be used to clean the medicine mixing barrel 1. The main pipe 2 can also discharge the sewage generated by cleaning through the sewage outlet 21. This design greatly simplifies the pipeline structure of the existing medicine mixer, making the medicine mixer easy to maintain and repair.

[0023] The mixing barrel 1 is used to mix a high-concentration drug with water to prepare a drug of appropriate concentration. Therefore, in some embodiments, the mixer further includes a stirring device 5, which includes a drive mechanism and an agitator. The agitator is disposed within the mixing barrel. The drive mechanism is in transmission connection with the agitator to drive the agitator to rotate, thereby rapidly dispersing the high-concentration drug. The drive mechanism can utilize a suitable motor.

[0024] In some embodiments, a water supply interface 6 is further provided on the top of the medicine mixing barrel 1, and water is supplied to the medicine mixing barrel 1 more quickly through the water supply interface 6. In other embodiments, the top of the medicine mixing barrel 1 can also be opened, and water is supplied to the medicine mixing barrel 1 through the opening.

[0025] In some embodiments, the dosing unit 3 includes a dosing tube 31 and a first metering pump 32. One end of the dosing tube 31 is connected to the main pipeline 2, and the other end forms a dosing interface for connecting to a storage tank or supply device that provides a high-concentration agent. The dosing interface is preferably designed as a quick-release structure to facilitate rapid replacement when mixing different agents. The first metering pump 32 is mounted on the dosing tube 31 to drive the agent into the mixing tank 1.

[0026] In some embodiments, the drug dispensing unit 4 includes a drug dispensing pipe 41 and a second metering pump 42. One end of the drug dispensing pipe 41 is connected to the main pipeline 2, and the other end of the drug dispensing pipe 41 forms a drug dispensing interface for connecting to subsequent water treatment equipment. The drug dispensing interface is preferably configured as a quick-release interface. The second metering pump 42 is mounted on the drug dispensing pipe 41 to drive the drug in the drug mixing tank 1 to flow out at a predetermined rate.

[0027] In some embodiments, a liquid level switch is also provided in the medicine mixing barrel 1, and the liquid level switch is connected to the first metering pump 31 and the second metering pump 42 to control their start or shut down respectively. When the liquid level drops to the low point of the liquid level switch, the liquid level switch controls the second metering pump 42 to close, controls the first metering pump 32 to open, and replenishes the medicine into the medicine mixing barrel 1. Preferably, the driving mechanism of the stirring device 5 and the valve of the water supply interface 6 can also be connected to control the stirring device 5 to start stirring, and the water supply interface 6 to replenish clean water into the medicine mixing barrel 1. When the liquid level rises to the high point of the liquid level switch, the liquid level switch controls the valves of the first metering pump 32 and the water supply interface 6 to close, controls the second metering pump 42 to open, and supplies medicine to the outside. It is easy to understand that the medicine mixer also has an electrical control cabinet 7 that integrates the control circuit.

[0028] In some embodiments, the drug mixer further includes a safety device 8, which includes a safety pipe 81, a pressure valve, and a buffer tank 82. One end of the safety pipe 81 is connected to the buffer tank 82, and the other end is connected to the main pipeline 2 and / or the dosing pipe 31 and / or the drug outlet pipe 41 via the pressure valve. The corresponding pressure valve opens only when the pressure in the main pipeline 2, the dosing pipe 31, or the drug outlet pipe 41 exceeds a threshold value set by the pressure valve.

[0029] If the main pipeline 2, dosing pipe 31, or discharge pipe 41 is blocked, the continued operation of the first metering pump 32 or the second metering pump 42 will cause the internal pressure of the pipeline to increase, potentially damaging the equipment. Therefore, safety device 8 is installed. When the pressure in the pipeline exceeds the threshold of the pressure valve, the pressure valve opens, allowing the liquid in the pipeline to flow into the buffer tank 82, preventing excessive pressure from damaging the equipment.

[0030] In a preferred embodiment, the safety device 8 further includes a pressure relief valve 83 provided on the safety pipe 81. When the buffer tank 82 is full, the pressure in the pipeline will continue to rise. When it exceeds the threshold of the pressure relief valve 82, the pressure will flow out of the pressure relief valve 83 to release pressure, thereby protecting the equipment.

[0031] See Figure 2 The present invention provides a dosing device, which includes: a plurality of mixers 100, which can be used to prepare different reagents, such as catalysts, PAC, sodium carbonate, organic sulfur, etc.

[0032] In some embodiments, the dosing equipment further includes a stepping platform 200 arranged on the side of the mixer 100. The stepping platform 200 has steps for easy entry of the operator and has a suitable height. When the operator stands on the stepping platform 200, he can easily operate the top of the mixing barrel 1.

[0033] Compared with the existing technology, the medicine mixer provided by the present invention is provided with a main pipeline, and the medicine adding unit and the medicine discharging unit are both connected to the main pipeline. The medicine adding unit transports high-concentration medicine and clean water into the medicine mixing barrel through the main pipeline, and the medicine discharging unit outputs the configured medicine through the main pipeline. The main pipeline can also discharge the sewage generated by cleaning. This design greatly simplifies the pipeline structure of the existing medicine mixer, making the medicine mixer easy to maintain and repair.

[0034] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
