[0003] However, in the existing technology, steel mills need a large amount of water for cooling during steelmaking, and a large amount of wastewater is also generated during the production process. Direct discharge not only pollutes the environment, but also causes waste of resources. At the same time, the wastewater in the production process is prone to impurities. If it is directly reused, it is easy to affect the quality of steelmaking processing. Therefore, it needs to be solved. At the same time, when some circulating water pools are in use, when excessive and rapid drainage occurs, it is easy to cause sewage to overflow the pool. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0034] Example 1, as Figure 1-4 As shown, the utility model provides a circulating water pool for a steel plant, comprising: a primary water pool 1; two limit cavities 101, which are opened on the surface of the primary water pool 1 at symmetrical positions; and further comprising: a high-efficiency water pump 106, which is connected to the surface of one side of the primary water pool 1 through a pipeline, and the high-efficiency water pump 106 is connected to a cooling tower 107 through a pipeline; a treatment box 104, which is connected to the surface of the primary water pool 1 away from the high-efficiency water pump 106 through a pipeline, and a card plate 105 is movably embedded in the interior of the treatment box 104; two baffles 1051, which are fixedly installed at symmetrical positions on the surface of the card plate 105, and the surfaces of the two baffles 1051 are slidably embedded in the interior of the treatment box 104.

[0035] A connecting pipe is provided at the end of the cooling tower 107 away from the high-efficiency water pump 106, and a connecting pipe is provided at the end of the treatment tank 104 away from the primary water tank 1. A first filter plate 1052 is fixedly mounted on the surface of the clamping plate 105, and a mounting plate 1054 is fixedly mounted on the top surface of the first filter plate 1052. One side of the mounting plate 1054 is bolted to the top surface of the treatment tank 104, and a second filter plate 1053 is fixedly mounted on one side of the mounting plate 1054.

[0036] In this embodiment, when in use, the drain outlet of the production line is connected through the connecting pipe at one end of the treatment box 104. When the sewage enters the interior of the treatment box 104 through the pipe, the first filter plate 1052 and the second filter plate 1053 on the surface of the card plate 105 cooperate to filter the sewage. At the same time, the interior of the first filter plate 1052 and the second filter plate 1053 can be filled with activated carbon or fiber tissue for filtering, and the filter holes on the surface of the second filter plate 1053 are larger than the filter holes of the first filter plate 1052, which blocks impurities in the sewage. When the bolts on the surface of the mounting plate 1054 are removed, the baffle 1051 is driven to move inside the treatment box 104 to take out impurities, perform regular cleaning, and improve the sewage filtration effect.

[0037] In embodiment 2, one side surface of the second filter plate 1053 is fixedly mounted on the surface of the clamping plate 105, a limiting groove 102 is provided on the inner wall at the symmetrical position of the first-level water pool 1, a secondary water pool 2 is provided on the outer surface of the first-level water pool 1, a through hole 103 is provided on the symmetrical surface of the first-level water pool 1, a limiting plate 1011 is slidably embedded in the two limiting cavities 101, a connecting rod 1012 is fixedly mounted on the opposite surfaces of the two limiting plates 1011, an anti-overflow plate 1013 is provided on the opposite surfaces of the two connecting rods 1012, the two connecting rods 1012 are slidably embedded in the limiting groove 102, and a circular hole 1014 is provided on the surface of the two limiting plates 1011.

[0038] In this embodiment, when the water inside the primary water tank 1 is too high and contacts the anti-overflow plate 1013, the connecting rod 1012 on the surface rises inside the limit groove 102, and the limit plate 1011 rises inside the limit cavity 101. At this time, the limit plate 1011 blocks the through hole 103, so that water is discharged from the top of the primary water tank 1 to the inside of the secondary water tank 2. The high-efficiency water pump 106 on the surface of the primary water tank 1 works, driving the water to be transmitted through the pipeline to the inside of the cooling tower 107 for cooling, and then cooperates with the connecting pipe to connect the water inlet of the steelmaking line to achieve the effect of water circulation. At the same time, when the water level inside the primary water tank 1 reaches a safe level, the circular hole 1014 on the surface of the limit plate 1011 coincides with the through hole 103, so that the water inside the secondary water tank 2 flows into the inside of the primary water tank 1 to prevent overflow.

[0039] Working principle: When in use, the connecting pipe at one end of the treatment box 104 is connected to the drain outlet of the production line. When the sewage enters the interior of the treatment box 104 through the pipe, the first filter plate 1052 and the second filter plate 1053 on the surface of the card plate 105 cooperate to filter the sewage. At the same time, the interior of the first filter plate 1052 and the second filter plate 1053 can be filled with activated carbon or fiber tissue for filtering, and the filter holes on the surface of the second filter plate 1053 are larger than the filter holes on the surface of the first filter plate 1052, which blocks impurities in the sewage. When the bolts on the surface of the mounting plate 1054 are removed, the baffle 1051 is driven to move inside the treatment box 104, taking out impurities, and performing regular cleaning to improve the sewage filtration effect, so that the discharged sewage enters the interior of the primary water tank 1 through the pipe. At the same time, chemical agents such as coagulants, fungicides, corrosion inhibitors and scale inhibitors can be put into the interior of the primary water tank 1 to perform filtering. In order to improve the purification effect in one step and prevent the quality of steelmaking from being affected by water quality, a secondary water pool 2 is provided on the outer surface of the primary water pool 1. When the water inside the primary water pool 1 is too high and contacts the anti-overflow plate 1013, the connecting rod 1012 on the surface rises inside the limit groove 102, and the limit plate 1011 rises inside the limit cavity 101. At this time, the limit plate 1011 blocks the through hole 103, so that water is discharged from the top of the primary water pool 1 to the inside of the secondary water pool 2, and the high-efficiency water pump 106 on the surface of the primary water pool 1 works to drive the water to be transmitted through the pipeline to the inside of the cooling tower 107 for refrigeration, and then cooperates with the connecting pipe to connect the water inlet of the steelmaking line to achieve the effect of water circulation. At the same time, when the water level inside the primary water pool 1 reaches a safety level, the circular hole 1014 on the surface of the limit plate 1011 coincides with the through hole 103, so that the water inside the secondary water pool 2 flows into the inside of the primary water pool 1 to prevent overflow.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
