Description

Technical Field

[0001] This utility model relates to the field of cooling equipment, specifically a cooling device for the production of corrosion and scale inhibitors. Background Technology

[0002] Corrosion and scale inhibitors are classified according to their phosphorus content into phosphorus-free corrosion and scale inhibitors, low-phosphorus corrosion and scale inhibitors, and ordinary corrosion and scale inhibitors. Corrosion and scale inhibitors are particularly effective in controlling pitting corrosion in metal equipment, providing a superior protective film against pitting corrosion and effectively preventing metal corrosion. The production of corrosion and scale inhibitors requires adding various raw materials to a reaction vessel, where they are thoroughly mixed and heated. Finally, the finished product is discharged.

[0003] After the scale inhibitor is produced, its temperature is often high, and it needs to be cooled before it can be collected. Currently, when cooling down, a condenser pipe is installed at the discharge pipe and connected to the cooling water circulation system to absorb the heat of the product in the discharge pipe and quickly reduce the product temperature. However, cooling the product solely through the condenser pipe is not very effective and needs to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a cooling device for the production of corrosion and scale inhibitors.

[0005] To solve the above problems, the technical solution of this utility model is: a cooling device for the production of corrosion and scale inhibitors, comprising a precooling tank and a cooling tank, wherein a transfer pump is connected between the precooling tank and the cooling tank;

[0006] The precooling tank has an inner cylinder inside, and a water storage cavity is formed between the inner cylinder and the inner wall of the precooling tank. A water inlet pipe is provided at the bottom of the water storage cavity, and a water outlet pipe is provided on the upper side. A baffle extending to the lower part of the inner cylinder is fixedly connected to the top of the inner cylinder. The baffle divides the inner cylinder into cavity one and cavity two. A feed pipe is provided on the upper side of one side of cavity two, and a lower discharge pipe and an upper discharge pipe connected to the conveying pump are provided on the side of cavity two.

[0007] The cooling tank has two cylindrical sections, one inside and one outside, forming a material hopper between them. The top of the material hopper is connected to a feed pipe for a conveying pump, and the bottom is connected to a discharge pipe. A spiral guide plate is installed inside the material hopper. The inner side of the cylindrical section is a water storage chamber, and the cylindrical section and the cooling tank form a water storage chamber. The bottom of the water storage chamber and the water storage chamber are connected to a water inlet pipe, and the top of the water storage chamber and the water storage chamber are connected to a water outlet pipe.

[0008] Furthermore, the water storage chamber is equipped with a partition, which is located on the same plane as the baffle. The partition divides the water storage chamber into two independent water tanks. The bottom of the two water tanks is connected to the inlet pipe, and the top is connected to the outlet pipe.

[0009] Furthermore, both cavity one and cavity two are rotatably equipped with stirring shafts, and multiple sets of stirring blades are installed on the stirring shafts. A motor for driving the stirring shafts to rotate is installed on the top of the precooling tank.

[0010] Furthermore, the lower discharge pipe is connected to the inlet of the conveying pump, and the upper discharge pipe is connected to the lower discharge pipe through a conduit. Both the upper and lower discharge pipes are equipped with solenoid valves, and there are two solenoid valves on the lower discharge pipe, located on both sides of the conduit.

[0011] Furthermore, a spiral guide plate is installed inside the water storage cavity three.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 4 As shown, a cooling device for the production of corrosion and scale inhibitors includes a precooling tank 1 and a cooling tank 2. A transfer pump 3 is connected between the precooling tank 1 and the cooling tank 2. The transfer pump 3 can be a peristaltic pump.

[0020] The precooling tank 1 has an inner cylinder 4 inside, and a water storage cavity 1 is formed between the inner cylinder 4 and the inner wall of the precooling tank 1. The bottom of the water storage cavity 1 is provided with a water inlet pipe 5, and the upper side is provided with a water outlet pipe 6. A baffle 7 extending to the lower part of the inner cylinder 4 is fixedly connected to the top of the inner cylinder 4. The baffle 7 divides the inner cylinder 4 into a cavity 1 and a cavity 2. The upper side of one side of the cavity 1 is provided with a feed pipe 8, and the side of the cavity 2 is provided with a lower discharge pipe 9 and an upper discharge pipe 10 connected to the conveying pump 3. A partition 11 is provided inside the water storage cavity 1. The partition 11 and the baffle 7 are located on the same plane, and the partition 11 divides the water storage cavity 1 into two. The two water tanks are connected at the bottom to the inlet pipe 5 and at the top to the outlet pipe 6. Both chambers 1 and 2 are rotatably equipped with stirring shafts 12. Multiple stirring blades 13 are installed on the stirring shafts 12. The top of the precooling tank 1 is equipped with a motor 14 for driving the stirring shafts 12. The lower discharge pipe 9 is connected to the inlet of the conveying pump 3. The upper discharge pipe 10 is connected to the lower discharge pipe 9 through a conduit 15. Solenoid valves are installed on both the upper discharge pipe 10 and the lower discharge pipe 9. There are two solenoid valves on the lower discharge pipe 9, located on both sides of the conduit 15.

[0021] Connect the feed pipe 8 to the output pipe of the reaction tank, and connect the inlet pipe 5 and outlet pipe 6 to the cooling water circulation system to achieve the circulation of cold water in the two water chambers. The corrosion and scale inhibitor enters the first chamber and then the second chamber. The cold water in the two water chambers can cool the corrosion and scale inhibitor in the first and second chambers. Turn on the motor 14. The motor 14 drives the stirring blade 13 to rotate through the stirring shaft 12 to stir the corrosion and scale inhibitor and make it cool more evenly. Open the solenoid valve on the upper outlet pipe 10 and the solenoid valve on the side of the lower outlet pipe 9 away from the precooling tank 1, and turn on the delivery pump 3 to discharge the precooled corrosion and scale inhibitor. When the liquid level of the corrosion and scale inhibitor in the inner cylinder 4 is lower than that of the upper outlet pipe 10, the solenoid valve on the side of the lower outlet pipe 9 close to the precooling tank 1 can be opened to continue to discharge the corrosion and scale inhibitor.

[0022] The cooling tank 2 has a first cylinder 16 and a second cylinder 17 arranged from the inside out. A material hopper is formed between the first cylinder 16 and the second cylinder 17. The top of the material hopper is provided with a feed pipe 18 connected to the conveying pump 3, and the bottom is provided with a discharge pipe 19. A spiral guide plate 20 is installed inside. The inner side of the first cylinder 16 is a second water storage chamber. A third water storage chamber is formed between the second cylinder 17 and the cooling tank 2. The bottom of the second water storage chamber and the third water storage chamber are connected to a second water inlet pipe 21, and the top of the third water storage chamber is connected to a second water outlet pipe 22. A spiral guide plate 23 is installed inside the third water storage chamber.

[0023] Connect the inlet pipe 21 and outlet pipe 22 to the cooling water circulation system. The delivery pump 3 delivers the pre-cooled corrosion and scale inhibitor to the material silo. The corrosion and scale inhibitor slides down along the guide plate 20. The cold water in the water storage chambers 2 and 3 can achieve secondary cooling of the corrosion and scale inhibitor. The spiral guide plate 20 can increase the flow time of the corrosion and scale inhibitor and further improve the cooling effect.

[0024] In practical use, the corrosion and scale inhibitors in the two water tanks are cooled by cold water in the first and second chambers respectively. The motor 14 drives the stirring blade 13 to rotate and stir the corrosion and scale inhibitors, thus achieving pre-cooling of the corrosion and scale inhibitors. After entering the cooling tank 2, the corrosion and scale inhibitors slide down along the guide plate 20. The cold water in the second and third water storage chambers can achieve secondary cooling of the corrosion and scale inhibitors. The spiral guide plate 20 can increase the flow time of the corrosion and scale inhibitors, further improving the cooling effect.
