Description

Technical Field

[0001] This utility model relates to the field of corrosion and scale inhibitor filling, specifically a high-efficiency mixing device for filling corrosion and scale inhibitors. Background Technology

[0002] Currently, to ensure that heat exchange equipment and heating pipelines are not affected by corrosion and scale, and to improve energy utilization efficiency, the requirements for water quality in heating systems are becoming increasingly stringent. For the anti-corrosion, descaling, and softening treatments of circulating water in heating networks, the most commonly used agent is the black solid YZ101 anti-corrosion and scale inhibitor. This scale inhibitor requires hot water above 35°C to dissolve completely. Previously, it was added to the water tank by simply stirring it in a bucket. This method resulted in incomplete dissolution of the scale inhibitor, with a dissolution rate of only 60%-70%. The undissolved scale inhibitor accumulated in the tank, leading to waste and requiring frequent tank cleaning.

[0003] In view of the above problems, this utility model is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-efficiency mixing device for adding corrosion and scale inhibitors, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0006] This utility model provides a high-efficiency mixing device for adding anti-corrosion and scale inhibitors, including a storage tank, a mixing tank, and a connecting pipe. The mixing tank is located at the corner of the storage tank, and the connecting pipe connects the mixing tank and the storage tank. A first filter cylinder is provided on the connecting pipe.

[0007] The upper surface of the mixing tank is provided with a filling port, a water inlet pipe and a motor. The water inlet pipe connects to the interior of the mixing tank. The drive shaft of the motor faces downward and is provided with a shaft. The shaft is vertical and located inside the mixing tank. The lower end of the shaft is close to the inner bottom surface of the mixing tank. Multiple stirring blades are provided around the lower end of the shaft.

[0008] A support plate is horizontally arranged on the lower side of the medicine storage tank. A self-priming pump is arranged on the upper surface of the support plate. The inlet of the self-priming pump is connected to the medicine storage tank through a liquid outlet pipe. A second filter cylinder is arranged on the liquid outlet pipe.

[0009] Preferably, the outer surface of the mixing tank is provided with a main drain pipe that connects to the inside of the mixing tank, and the outer surface of the medicine storage tank is provided with a secondary drain pipe that connects to the inside of the medicine storage tank. The end of the secondary drain pipe that is away from the medicine storage tank is connected to the main drain pipe.

[0010] Preferably, a first valve is provided on the connecting pipe, a second valve is provided on the main sewage pipe, and a third valve is provided on the secondary sewage pipe.

[0011] Preferably, the first filter cartridge has a filtration mesh size of 40 mesh, and the second filter cartridge has a filtration mesh size of 20 mesh.

[0012] Preferably, the shaft is located at the vertical centerline inside the mixing tank.

[0013] Preferably, a power control box is also provided on the side of the medicine storage box.

[0014] Preferably, the bottom corners of the medicine storage box and the bottom corners of the support plate are provided with feet.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] During use, staff add the appropriate weight of scale inhibitor into the mixing tank through the filling port according to the water volume and real-time pH value. Then, hot water above 35℃ is added into the mixing tank through the water inlet pipe. After that, the motor drives the shaft to rotate, and the stirring blades rotate, which can fully mix the scale inhibitor with the hot water, so that the scale inhibitor is fully dissolved in the hot water.

[0017] Then, the first valve is opened. Since the connecting pipe connects the mixing tank and the storage tank, the scale inhibitor solution in the mixing tank flows into the storage tank. The first filter can filter out large particles in the scale inhibitor solution. After a period of sedimentation, the scale inhibitor solution in the storage tank starts to work. The scale inhibitor solution in the storage tank flows out through the outlet pipe. After being filtered by the second filter, it is discharged into the inner water tank and then replenished into the pipeline system by the water replenishment pump.

[0018] When the medicine storage tank and mixing tank need to be cleaned after long-term use, cleaning water is sent into the medicine storage tank and mixing tank. After cleaning, the sewage in the mixing tank flows out through the main drain pipe, and the sewage in the medicine storage tank flows out through the secondary drain pipe.

[0019] This device can achieve a scale inhibitor dissolution rate of about 90%-95%, effectively preventing scale buildup, protecting equipment, reducing cleaning frequency, and improving the overall operating efficiency of the device. Attached Figure Description

[0026] like Figure 1-3 As shown, a high-efficiency mixing device for adding anti-corrosion and scale inhibitor includes a storage tank 1, a mixing tank 2, and a connecting pipe 11. The mixing tank 2 is located at the corner of the storage tank 1. The connecting pipe 11 connects the mixing tank 2 and the storage tank 1. A first filter cylinder 13 is provided on the connecting pipe 11. When the scale inhibitor aqueous solution passes through the connecting pipe 11, it can be filtered by the first filter cylinder 13.

[0028] A support plate 16 is horizontally arranged on the lower side of the medicine storage tank 1. A self-priming pump 17 is arranged on the upper surface of the support plate 16. The inlet of the self-priming pump 17 is connected to the medicine storage tank 1 through a liquid outlet pipe 18. A second filter cylinder 19 is arranged on the liquid outlet pipe 18.

[0029] The outer surface of the mixing tank 2 is provided with a main drain pipe 26 that connects to the inside of the mixing tank 2, and the outer surface of the medicine storage tank 1 is provided with a secondary drain pipe 14 that connects to the inside of the medicine storage tank 1.

[0035] In summary: During use, the operator adds the appropriate weight of scale inhibitor to the mixing tank 2 through the filling port 21 according to the water volume and real-time pH value.

The first filter cartridge 13 can filter out large particles in the scale inhibitor solution. After a period of sedimentation, the scale inhibitor aqueous solution in the storage tank 2 is activated by the self-priming pump 17.
