DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] As Figures 1 to 2As shown, a metering storage tank for producing corrosion inhibitors includes a tank body 1. A feed pipe 2 is provided on the upper side of the tank body 1, and a discharge pipe 3 is provided on the lower side. A solenoid valve 11 and a flow meter 12 are respectively installed at the inner and outer ends of the discharge pipe 3. An ultrasonic level gauge 4 is installed inside the tank body 1. A horizontal plate 13 is fixedly connected to the upper part of the tank body 1, and the ultrasonic level gauge 4 is installed at the bottom of the horizontal plate 13.

[0020] The ultrasonic level gauge 4 can monitor the liquid level inside the tank 1 in real time, making it easy to understand the amount of corrosion inhibitor stored inside the tank 1. The flow meter 12 can measure the discharged corrosion inhibitor.

[0021] like Figure 2 As shown, the tank body 1 has an opening at the top and a discharge pipe 5 at the bottom. A cover plate 6 is installed at the opening, and a valve 7 is installed on the discharge pipe 5. An agitator shaft 8 passes through the middle of the cover plate 6. Two spiral blades 9 are installed on the lower part of the agitator shaft 8 through multiple connecting rods 15. The two blades 9 are centrally symmetrical about the agitator shaft 8. A geared motor 10 for driving the agitator shaft 8 to rotate is installed on the top of the cover plate 6. A support frame 16 for supporting the geared motor 10 is also installed on the top of the cover plate 6.

[0022] The geared motor 10 drives the paddle 9 to rotate through the stirring shaft 8, which can mix the corrosion inhibitor evenly, prevent the corrosion inhibitor from precipitating and stratifying, and ensure that the corrosion inhibitor is uniform and effective when used.

[0023] When it is necessary to clean the inside of tank 1, open the valve and discharge the residual corrosion inhibitor in tank 1 through the discharge pipe 5. Open the cover plate 6 to go deep into the inside of tank 1 for cleaning. The wastewater generated during cleaning can be discharged through the discharge pipe 5.

[0024] like Figure 1 and Figure 3 As shown, a filter assembly is installed in the middle of the discharge pipe 3. The filter assembly includes a bottom shell 17, a protective cover 18 is threaded to the top of the bottom shell 17, a fixing ring 19 is fixed to the bottom inside, and an input pipe 20 and an output pipe 21 are respectively provided on both sides. A filter cylinder 22 is threaded to the top of the fixing ring 19, and one end of the input pipe 20 is connected to the fixing ring 19.

[0025] The corrosion inhibitor first enters the bottom shell 17 when it is discharged, and is filtered by the filter cartridge 22 before being discharged for use, which effectively prevents the sediment from clogging the pipeline or the filling pump.

[0026] In specific use, the device is connected to an external control system, the speed reducer 10 drives the paddle 9 to rotate to mix the corrosion inhibitor, prevents the corrosion inhibitor from being deposited and layered, and ensures that the corrosion inhibitor is uniform and effective when used; when part of the corrosion inhibitor is deposited, the corrosion inhibitor enters the bottom shell 17 first when discharged, is filtered by the filter cartridge 22 and then discharged for use, thereby effectively preventing the deposits from blocking the pipeline or the filling pump, thereby ensuring continuous addition of the corrosion inhibitor and pipeline corrosion prevention effect.
