Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ingot processing, in particular to a turbid circulating water system. Background Art

[0002] A turbid circulating water system is a direct-circulation cooling water system, particularly suitable for cooling ingots and other materials in industrial environments such as aluminum foundries. In this system, the circulating water comes into direct contact with the materials or equipment being cooled, resulting in the entrainment of a significant amount of impurities and dirt. Due to the high content of suspended solids and even high oil content in turbid circulating water, the water quality of this system is often turbid. To meet cooling and process requirements, turbid circulating water systems typically include equipment such as drainage ditches, sedimentation tanks, and biochemical treatment cooling towers to treat impurities and dirt in the circulating water.

[0003] For example, Chinese patent CN219264682U discloses a water-saving turbid circulating water system for an aluminum processing plant, comprising a turbid circulating cold water tank, a turbid circulating cold water pump, a self-cleaning filter I and a turbid circulating water supply network connected in sequence by pipes. Cooling water is transmitted from the turbid circulating water supply network to a hydraulic semi-continuous casting machine to cool the aluminum ingots produced therein, and then enters the turbid circulating water return network through a pipe. The turbid circulating water return network is connected in sequence by pipes to an oil separation sedimentation tank, a turbid circulating hot water tank, a turbid circulating hot water pump and a closed cooling tower. The water cooled in the closed cooling tower is returned to the turbid circulating cold water tank through a pipe.

[0004] However, this technology has the following problems: it only filters the cooling water in a single way, which cannot guarantee the water quality of the cooling water and reduces the cooling effect; and impurities that are not removed from the water will damage the machine.

[0030] When the present invention is in use, after the processing of the materials in the aluminum foundry is completed, the materials are sent to the cooling module 2 for cooling. Water cools the materials and impurities and oil on the materials are cooled in the cooling water. Then the cooling water and impurities are passed into the filtering module 3. The filtering module 3 performs a preliminary filtration on the impurities. The filtered materials then enter the separation module 4. Solid-liquid separation is achieved in the separation module 4. The lower filtrate of the separation module 4 returns to the filtering module 3 for further processing. Then the upper liquid of the separation module 4 is pumped into the impurity removal module 5. The impurity removal module 5 further filters and deoils the liquid. Then the treated water is passed into the cooling module 2 to cool the materials in the aluminum foundry again. The central control module 1 detects the cooling condition of the materials and the processing condition of the cooling water in real time, and then uploads the data information to the terminal 7 through the communication module 6.

[0031] This utility model uses the turbidity circulating water system to continuously circulate and cool ingots and other materials, effectively controlling the material temperature and ensuring the smooth progress of the production process. It removes turbidity and oil from the water to ensure the quality and stability of the circulating water.

[0032] In some embodiments, as Figure 1-3As shown, as a preferred embodiment of the present invention, the cooling module 2 includes a closed cooling tower 21 , a cold water pump 22 and a cooling pool 23 , and the closed cooling tower 21 is connected to the cooling pool 23 via the cold water pump 22 .

[0033] The cooling pool 23 is connected to the filtering module 3 , and the closed cooling tower 21 is connected to the impurity removal module 5 .

[0034] The filtration module 3 includes a filter tank 31, a centrifugal pump 32, a sedimentation tank 33, a dosing device 34 and a lifting pump 35. The filter tank 31 is connected to the cooling tank 23 through a slag flushing ditch, the filter tank 31 is connected to the sedimentation tank 33 through a centrifugal pump 32, the dosing device 34 is connected to the sedimentation tank 33, and the sedimentation tank 33 is connected to the lifting pump 35.

[0035] The sedimentation tank 33 is connected to the separation module 4 .

[0036] The separation module 4 includes a separation and purification tank 41, a magnetic press dehydrator 42, a slag tank 43, a filtrate tank 44 and a circulation pump 45. The separation and purification tank 41 is connected to the sedimentation tank 33 through the lifting pump 35, the separation and purification tank 41 is connected to the magnetic press dehydrator 42, the magnetic press dehydrator 42 is connected to the slag tank 43 and the filtrate tank 44, and the filtrate tank 44 is connected to the sedimentation tank 33 through the circulation pump 45.

[0037] The filtrate pool 44 is connected to the impurity removal module 5 .

[0038] The impurity removal module 5 includes a flotation water pump 51, an air flotation device 52, a regulating water tank 53, a disc oil remover 54 and a hot water pump 55. The flotation water pump 51 is connected to the filtrate tank 44, the air flotation device 52 is connected to the flotation water pump 51, the regulating water tank 53 is connected to the disc oil remover 54, and the regulating water tank 53 is connected to the closed cooling tower 21 through the hot water pump 55.

[0039] When the present invention is in use, the materials produced by the aluminum foundry are placed in the cooling pool 23, and the cooling water in the cooling pool 23 cools the materials. The cooled water enters the filter pool 31 for treatment through the slag flushing ditch. The cooling water is preliminarily treated in the filter pool 31, and the large impurities in the water are filtered out. Then, the cooling water in the filter pool 31 is pumped into the sedimentation pool 33 by the centrifugal pump 32, and the dosing device 34 adds micro-magnetic coagulant to the sedimentation pool 33. The polymer components in the micro-magnetic coagulant use their long chain effect to adsorb and entangle many small sludge particles together to form larger particles. The magnetizing components in the micro-magnetic coagulant are integrated into the flocs to enhance the overall ferromagnetism of the flocs. Then, the lifting pump 35 pumps the solid-liquid mixture in the sedimentation pool 33 to the separation and purification pool 41, and the magnetic pressing dehydrator 42 uses the high-strength magnetic force of the magnetic suction roller to separate the ferromagnetic slag or magnetic flocs in the water. The separated slag blocks are then discharged into the slag pool 43, and the water enters the filtrate pool 44. After settling in the filtrate tank 44, the circulating pump 45 pumps the liquid containing the material in the lower layer of the filtrate tank 44 to the sedimentation tank 33 for further circulation and separation treatment. The flotation pump 51 pumps the upper layer of the liquid in the filtrate tank 44 to the flotation device 52. The flotation device 52 generates a large number of tiny bubbles, causing the suspended matter in the water to attach to the bubbles and float to the water surface as the bubbles rise, thereby achieving solid-liquid separation and further treating the water. The treated water enters the regulating water tank 53, and the disc oil remover 54 removes oil from the water in the regulating water tank 53. Then, the hot water pump 55 pumps the treated water in the regulating water tank 53 to the closed cooling tower 21, which cools the water. After that, the cold water pump 22 pumps the water in the closed cooling tower 21 into the cooling tank 23 to cool the materials produced by the aluminum casting plant. The present invention effectively controls the temperature of the production materials by continuously circulating and treating water to cool the materials, ensuring the smooth progress of the production process.

[0040] In some embodiments, as Figure 1-3 As shown, as a preferred embodiment of the present invention, the central control module 1 is electrically connected to the control ends of the cooling pool 23, the centrifugal pump 32, the magnetic press dehydrator 42, the circulating pump 45, the flotation water pump 51, the flotation device 52, the disc oil remover 54, and the hot water pump 55.

It can also detect the cooling situation of the material and the treatment of the cooling water in real time, and promptly feedback the water treatment situation to the terminal 7 through the communication module 6. Through real-time monitoring and automatic adjustment by the central control module 1, the system can ensure the stability of water quality and the optimization of cooling effect. At the same time, the central control module 1 can also predict potential failures and perform maintenance in advance to reduce the risk of production interruption.
