[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] In this technical solution, an internal impurity removal device for a corrosion-resistant pipe cooling tower includes a water tank 1, a cooling box body 2 installed on the upper end of the water tank 1, a number of support rollers 3 provided on the lower inner wall of the cooling box body 2, and an impurity filtration structure provided at the connection between the water tank 1 and the cooling box body 2. The impurity filtration structure includes a recovery pipe 4, a processing pipe 5, a filter screen 6, a conveying pipe 7, a partition frame 8, and a backflushing discharge assembly.

[0025] One end of the recovery pipe 4 is connected to one side of the cooling box 2, the top end of the processing pipe 5 is connected to the other end of the recovery pipe 4, the filter screen 6 is fixedly installed inside one side of the water tank 1, one end of the conveying pipe 7 is connected to the center of one end of the processing pipe 5, and the other end is embedded in the wall of one side of the water tank 1, the partition frame 8 is fixedly installed inside the processing pipe 5, one end of the backflushing discharge assembly is connected to the lower end of one side of the water tank 1, and the other end is connected to the lower end of the processing pipe 5.

[0026] In this technical solution, when cooling the anti-corrosion pipe, the worker first injects coolant into the water tank 1, then places the anti-corrosion pipe on top of several support rollers 3 inside the cooling box 2. The support rollers 3 provide rolling support for the anti-corrosion pipe. Then, by driving the cooling structure, the coolant in the water tank 1 is sprayed into the cooling box 2 to cool the anti-corrosion pipe. The sprayed coolant and washed-off impurities fall into the lower part of the cooling box 2 and are discharged through a recovery pipe 4 connected to one side of the cooling box 2. Due to the large weight of the impurities, as they... When the coolant enters the processing pipe 5, impurities in the coolant enter the partition frame 8 by their own gravity, and then fall into the lower end of the processing pipe 5 for preliminary treatment. The recovered coolant is then transported to the water tank 1 through the conveying pipe 7 for recycling. The coolant is then filtered a second time through the filter screen 6, leaving impurities on one side of the water tank 1. Finally, the backwash discharge assembly is opened to discharge the impurities on one side of the water tank 1 and the impurities at the lower end of the processing pipe 5 at the same time, ensuring the subsequent coolant delivery effect and increasing the overall service life of the cooling equipment.

[0027] In some technical solutions, reference Figure 1 The backflushing discharge assembly includes: discharge pipe 9, control valve 10, and three drain pipe groups 11;

[0028] One end of the discharge pipe 9 is connected to the lower end of one side of the water tank 1. The control valve 10 is installed on one side of the discharge pipe 9. The lower end of the treatment pipe 5 is connected to the discharge pipe 9. All three drainage pipe groups 11 are installed on one side of the discharge pipe 9.

[0029] In this technical solution, when cleaning the impurities in the treatment pipe 5 and the water tank 1, the control valve 10 at the upper end of the discharge pipe 9 is opened first, and then all three drain pipe groups 11 are opened. Under the flow inertia of the cooling liquid in the water tank 1, the impurities in the water tank 1 and the treatment pipe 5 are discharged.

[0030] In some technical solutions, reference Figure 1 The inner wall of the cooling box 2 is equipped with a cooling structure, which includes four spray pipe groups 12, a water inlet pipe 13 and a pump body 14.

[0031] Four spray pipe assemblies 12 are embedded in the inner wall of the cooling box 2. One end of the water inlet pipe 13 is connected to one end of the four spray pipe assemblies 12. The pump body 14 is fixedly installed on one side of the lower end of the water tank 1, and the liquid outlet end is connected to one end of the water inlet pipe 13.

[0032] In this technical solution, when cooling the anti-corrosion pipe, the pump body 14 operates to transport the cooling liquid in the water tank 1 to the four spray pipe groups 12 through the water inlet pipe 13. Finally, the cooling liquid is sprayed to the outside of the anti-corrosion pipe through the spray pipe groups 12 to achieve the purpose of cooling the anti-corrosion pipe.

[0033] In some technical solutions, reference Figure 1 The partition frame 8 is conical in shape, with an opening at the center. The upper end of the drain pipe assembly 11 is equipped with a drain valve 15, and the inlet pipe 13 is an arc-shaped inlet pipe 13.

[0034] Working Principle: In this technical solution, when cooling the anti-corrosion pipe, the operator first injects coolant into the water tank 1. Then, the anti-corrosion pipe is placed on top of several support rollers 3 inside the cooling tank 2. The support rollers 3 provide rolling support for the anti-corrosion pipe. During cooling, the pump 14 operates, transporting the coolant from the water tank 1 through the inlet pipe 13 to four spray pipe groups 12. Finally, the coolant is sprayed onto the outside of the anti-corrosion pipe through the spray pipe groups 12, achieving the purpose of cooling the anti-corrosion pipe. The sprayed coolant and washed-off impurities fall into the lower part of the cooling tank 2 and are discharged through the recovery pipe 4 connected to one side of the cooling tank 2. Due to the large weight of the impurities, when... As the coolant enters the processing pipe 5, impurities in the coolant enter the partition frame 8 by gravity and then fall to the lower end of the processing pipe 5 for initial treatment. The recovered coolant is then transported to the water tank 1 through the delivery pipe 7 for further recovery. The coolant undergoes secondary filtration through the filter screen 6, leaving impurities on one side of the water tank 1. When cleaning the impurities in the processing pipe 5 and the water tank 1, the control valve 10 at the upper end of the discharge pipe 9 is first opened, followed by the opening of all three drain pipe groups 11. The flow inertia of the coolant in the water tank 1 causes the impurities in the water tank 1 and the processing pipe 5 to be discharged, ensuring the subsequent coolant delivery effect and increasing the overall service life of the cooling equipment.
