Description

Technical Field

[0001] This application relates to the field of corrosion inhibitor dispensing technology, and in particular to a corrosion inhibitor dispensing device. Background Technology

[0002] In fields such as petrochemicals and water conservancy projects, metal equipment and pipelines are subject to long-term corrosion from various media. Applying corrosion inhibitors is a crucial protective measure to extend equipment lifespan. Traditional corrosion inhibitor application methods often rely on manual operation, involving manual pouring or transport via simple pipelines. This is not only labor-intensive but also makes precise control of the dosage difficult, easily leading to problems such as excessively high or low local concentrations of the corrosion inhibitor, resulting in uneven protective effects and even wasted agents.

[0003] Some automated dispensing equipment uses a structure where a single storage tank is directly connected to a pipeline, lacking a diversion and buffer design. During the transportation process, the corrosion inhibitor is prone to concentration stratification or pressure fluctuations, affecting the stability of dispensing. Furthermore, the equipment cannot flexibly adjust the dispensing volume according to changes in operating conditions, making it difficult to ensure a continuous and effective supply of corrosion inhibitor when system pressure and medium flow rate change.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

A first diversion tank is provided between the two support arms. A second diversion tank is installed at the bottom of the first diversion tank. A corrosion inhibitor storage tank is provided at the bottom of the second diversion tank. A suction pump is installed at the top of one side of the mounting frame.

[0008] Preferably, a regulating valve is installed on the filling pipe, and the output end of the filling pipe passes through the inner wall of the support arm and is connected to the diversion tank.

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a corrosion inhibitor dispensing device. (Refer to...) Figures 1-2 The system includes a mounting frame 1, with a set of support arms 2 symmetrically fixed to the bottom of the mounting frame 1. A diversion tank 7 is located between the two support arms 2. A second diversion tank 8 is installed at the bottom of the first diversion tank 7. A corrosion inhibitor storage tank 9 is located at the bottom of the second diversion tank 8. Fixed shafts 11 for support are connected between the support arms 2 and the inner walls of the second diversion tank 8 and the corrosion inhibitor storage tank 9. The mounting frame 1, as the basic frame, together with the symmetrical support arms 2 at the bottom, forms a stable support platform for the first diversion tank 7, the second diversion tank 8, and the corrosion inhibitor storage tank 9.

[0020] In this application, a suction pump 4 is installed at the top of one side of the mounting frame 1. The discharge end of the suction pump 4 is connected to a filling pipe 3, which is connected to the input end of the distribution tank 7. A regulating valve 5 is installed on the filling pipe 3. The output end of the filling pipe 3 passes through the inner wall of the support arm 2 and communicates with the distribution tank 7. The suction pump 4 provides power to drive the delivery of the corrosion inhibitor. With the regulating valve 5 on the filling pipe 3, the delivery pressure and flow rate of the corrosion inhibitor can be precisely adjusted.

[0021] In this application, the input end of the suction pump 4 is connected to a material pipe 6, and a set of distribution pipes 10 are fixed at equal intervals between the second distribution tank 8, the first distribution tank 7, and the corrosion inhibitor storage tank 9. The corrosion inhibitor is initially dispersed in the first distribution tank 7, and then introduced into the second distribution tank 8 through the distribution pipes 10 to achieve secondary distribution. The two-stage distribution mechanism ensures that the corrosion inhibitor is fully mixed and evenly distributed before entering the storage tank, avoiding local uneven concentration and laying the foundation for subsequent precise injection.

[0022] like Figure 3 As shown, the bottom of the corrosion inhibitor storage tank 9 has several equally spaced filling and discharging pipes 12, each equipped with a valve 13. The filling and discharging pipes 12 at the bottom of the corrosion inhibitor storage tank 9, in conjunction with the valves 13, achieve directional output of the corrosion inhibitor through gravity. Operators can flexibly adjust the filling speed and single-use volume by controlling the opening and closing of the valves 13; in conjunction with the regulating valve 5, a full range of control can be achieved, from micro-additions to large-scale injections, precisely adapting to the corrosion inhibition needs of different equipment.

[0023] The implementation principle of the corrosion inhibitor dispensing device in this application embodiment is as follows:

[0024] The device is based on the mounting frame 1. The symmetrical support arms 2 at the bottom provide stable support for the first distribution tank 7, the second distribution tank 8, and the corrosion inhibitor storage tank 9. The fixed shaft 11 further reinforces each tank to ensure stable operation of the device. During operation, the suction pump 4 is started. The suction pump 4 draws corrosion inhibitor from the external storage source through the material pipe 6. After being pressurized by the suction pump 4, the corrosion inhibitor is transported along the filling pipe 3.

[0025] The regulating valve 5 on the filling pipe 3 controls the flow rate of the corrosion inhibitor. The corrosion inhibitor enters the first distribution tank 7 through the output end of the filling pipe 3, where it is initially dispersed. It then flows into the second distribution tank 8 via the distribution pipe 10, achieving secondary distribution. After two stages of distribution, the corrosion inhibitor is evenly distributed into the corrosion inhibitor storage tank 9 for temporary storage. When it is necessary to add corrosion inhibitor to the target equipment or pipeline, the valve 13 on the filling outlet pipe 12 at the bottom of the corrosion inhibitor storage tank 9 is opened. Under gravity, the corrosion inhibitor is precisely delivered to the designated location through the filling outlet pipe 12. By controlling the opening and closing degrees of the regulating valve 5 and valve 13, the amount and speed of corrosion inhibitor can be flexibly adjusted to meet the corrosion inhibition requirements under different working conditions, ensuring uniform and stable addition of the corrosion inhibitor and effectively improving the corrosion inhibition effect.
