Description

Technical Field

[0001] The utility model relates to the technical field of metal plating, in particular to a water-cooled cooling component for galvanized annealing of strip steel. Background Art

[0002] During the production process of the galvanizing annealing furnace, the strip steel often remains at a high temperature after leaving the zinc pot. In order to ensure the quality and production efficiency of the strip steel, the strip steel must be cooled by a fan. During the cooling process, the fan needs to introduce a large amount of cold air, which acts directly on the surface of the strip steel by blowing air to achieve rapid cooling.

[0003] In traditional cooling system design, air from outside the plant is usually selected as the source of cooling air. This is because the temperature of the outside air is 15-20℃ lower than the temperature of the air inside the plant, which helps to improve the cooling efficiency. However, this air intake method has obvious defects.

[0004] First, the temperature change of the external environment has a significant impact on the cooling effect. In winter, the outdoor temperature may be as low as -15°C. At this time, the temperature of the cooling gas blown out is extremely low, which may cause too fast cooling after plating, which will have an adverse effect on the quality of the strip. On the contrary, in summer, the outdoor temperature may be as high as 35°C or above. At this time, the temperature of the cooling gas is high, and the cooling capacity is insufficient to meet production needs. This fluctuation in cooling effect caused by seasonal changes has brought challenges to the stability of the production process and product quality.

[0005] Secondly, this direct air intake design is also limited in terms of air volume adjustment. It can only change the air volume by adjusting the output of the fan, but cannot achieve precise cooling rate control. For some products that have specific requirements for the post-plating cooling process, this design cannot meet their production needs, limiting the flexibility and adaptability of the production line.

[0008] (II) Technical solution

[0009] A water-cooled cooling component for galvanized annealing of strip steel comprises a fan, one end of the fan is connected to a movable bellows, and the other end of the fan is connected to a third connecting pipe, one end of the third connecting pipe is connected to an air-water heat exchanger body, and one side of the air-water heat exchanger body is connected to a second connecting pipe, an outer surface of one end of the air-water heat exchanger body is connected to a first connecting pipe, and one end of the first connecting pipe is connected to a water pump, one end of the water pump is connected to a water tank, the other end of the air-water heat exchanger body is connected to a connecting end, and a first temperature sensor is provided on an outer surface of one side of the third connecting pipe.

[0010] Preferably, an electronic valve is provided on the outer surface of the third connecting pipe.

[0011] Preferably, a second temperature sensor is provided on one side of the movable bellows.

[0012] Preferably, a filter element is installed on the inner wall of the second connecting pipe, and a plurality of groups of filter screens are arranged on the inner wall of the filter element.

[0013] Preferably, a connecting plate is connected to one side of the filter screen, and a handle is fixedly mounted on the outer surface of the connecting plate.

[0014] Preferably, the outer surface of the filter element is wrapped with rubber.

[0015] Preferably, both ends of the handle are arc-shaped.

[0016] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0017] 1. The utility model realizes precise regulation of cooling water flow by introducing frequency conversion control of the air-water heat exchanger body and the water pump. This means that the cooling effect can be flexibly adjusted according to the real-time temperature and cooling requirements of the steel strip, thereby ensuring the stability of the cooling speed. At the same time, the frequency conversion control of the water pump can also reduce energy consumption and improve production efficiency. It also adopts the method of recycling cooling water, which not only saves water resources but also reduces the cost of wastewater treatment. After the cooling water exchanges heat with the hot air in the air-water heat exchanger, the cooling speed and cooling outlet temperature of the steel strip after it leaves the zinc pot can be stably controlled, reducing the influence of the external ambient temperature on the post-plating cooling process.

[0018] 2. The utility model measures the temperature of the cooled air in real time through the first temperature sensor and feeds the data back to the control system, thus realizing precise control of the air temperature. The design of this closed-loop control circuit makes the cooling process more intelligent and automated, reduces the error of human intervention, and improves production efficiency.

[0028] Furthermore, an electronic valve 8 is provided on the outer surface of the third connecting pipe 6. The setting of the electronic valve 8 can realize precise control of the flow rate of cooling air, further improve the stability of the cooling process, and by connecting with the control system, the electronic valve 8 can respond quickly according to actual needs, adjust the air flow rate, and improve production efficiency.

[0029] Furthermore, a second temperature sensor 111 is provided on one side of the mobile bellows 10. The second temperature sensor 111 can measure the temperature of the strip when it leaves the bellows in real time, provide accurate feedback data for the control system, and by combining with the closed-loop control circuit of the fan 9, it can achieve precise adjustment of the cooling rate of the strip to meet production needs.

[0030] Furthermore, a filter element 511 is installed on the inner wall of the second connecting pipe 5, and a plurality of filter screens 512 are arranged on the inner wall of the filter element 511. The combination design of the filter element 511 and the filter screen 512 can effectively filter impurities and particulate matter in the cooling gas, ensuring that the cooling gas entering the air-water heat exchanger body 1 is of high quality. This helps to improve the overall working efficiency of the cooling system and reduce equipment wear or failure caused by impurities.

[0031] Furthermore, a connecting plate 513 is connected to one side of the filter screen 512, and a handle 514 is fixedly installed on the outer surface of the connecting plate 513. The presence of the handle 514 enables the staff to maintain a stable grip when operating the filter screen 512, avoiding accidental injuries caused by improper operation or loss of control, enhancing the safety of operation, and making it easier for people to disassemble and install the filter element 511.

[0034] Working principle: First, cooling water is pumped out from the water tank 4 through the water pump 3 and enters the air-water heat exchanger body 1 through the first connecting pipe 2. The water pump 3 adopts frequency conversion control, and the water flow rate can be adjusted as needed to control the cooling effect. The cooling water exchanges heat with the hot air in the air-water heat exchanger body 1, absorbs the heat in the air, flows out through the connecting end 911, and is finally transported to the water supply plant for cooling treatment and then recycled. At the same time, the hot air enters the air-water heat exchanger body 1 through the second connecting pipe 5, and the temperature is reduced after cooling. The first temperature sensor 7 measures the temperature of the cooled air in real time and feeds the data back to the control system. The control system controls the flow rate of cooling water by adjusting the speed of the water pump 3 according to the preset temperature requirements, thereby realizing precise control of the air temperature.

The control system achieves precise control of the strip cooling rate by adjusting the speed and air volume of the fan 9 according to the preset strip temperature requirement.
