Description

Technical Field

[0001] The utility model relates to the technical field of cooling beds, in particular to a new type of section steel cooling bed. Background Art

[0002] A cooling bed is a working surface for effectively cooling rolled products (such as deformed steel bars, round steel, steel pipes, etc.) in the metallurgical rolling industry. The cooling bed consists of a mechanical drive system, a water cooling system, a cooling bed working surface, fixed brackets, etc. The cooling beds mainly include tooth-pulling cooling beds, rack walking beam cooling beds, claw-type cooling beds, carrying chain cooling beds, rotary table cooling beds, etc.

[0003] In the process of section steel rolling production, a cooling bed is also required to cool the produced section steel. Since the temperature of the freshly rolled section steel is relatively high, there are generally two forms of cooling on the cooling bed: natural cooling and water cooling. The natural cooling method has a long cooling time and low cooling efficiency, reducing the production speed; when using the water cooling method for temperature reduction, a large amount of water vapor is generated when the cooling water is sprayed on the section steel, and the water vapor emitted into the air will cause the humidity in the workshop to rise. In a high-temperature and high-humidity environment, it will cause workers to suffer from heat stroke and endanger the health of workers. Content of the Utility Model

[0029] Such as Figure 1 and Figure 2As shown in the figure, a new type of section steel cooling bed includes a cooling bed body 1, a heat collecting cover 2, baffles 3, a spray pipe 4, a water collecting tank 5 and an exhaust pipe 6. The rolled section steel is placed on the cooling bed body 1. The heat collecting cover 2 is arranged above the cooling bed body 1, and the section steel is covered inside the heat collecting cover 2. The heat collecting cover 2 is in a "door" - shaped structure formed by enclosing two side plates and a top plate. The heat collecting cover 2 is provided with an inlet and an outlet. There are two baffles 3 which are vertically slidably arranged at the inlet and outlet of the heat collecting cover 2 for sealing the heat collecting cover 2. When the section steel enters the cooling bed body 1, the baffle 3 is opened upward to allow the section steel to enter. When the section steel completely enters, the baffle 3 is closed to seal the heat collecting cover 2. After sealing, the heat on the section steel cannot be dissipated from the heat collecting cover 2, which can reduce the workshop temperature to a certain extent. After sealing, a plurality of nozzles are arranged on the spray pipe 4, and cooling water is sprayed from the nozzles of the spray pipe 4 onto the section steel to cool and lower the temperature of the section steel. A part of water vapor will be generated during the spraying process, and the water vapor drifts upward. Due to the function of the heat collecting cover 2, the water vapor cannot be dissipated from the heat collecting cover 2 to the outside. After the section steel is cooled by the cooling water, the cooling water drops into the water collecting tank 5 below the cooling bed body 1 for collection. A water pump is connected to the water collecting tank 5, and the water pump is connected to the spray pipe 4. The collected cooling water can be recycled again to reduce the waste of water resources. One end of the exhaust pipe 6 is connected to the side plate or the top plate of the heat collecting cover 2, and the other end is connected to a waste heat recovery device. An exhaust fan is arranged on the exhaust pipe 6. The heat and water vapor in the heat collecting cover 2 can be extracted by the exhaust pipe 6 to the waste heat recovery device for waste heat recovery to avoid heat waste.

[0030] It should be noted that the waste heat recovery device is a waste heat boiler. The temperature of the gas extracted by the exhaust pipe 6 is relatively high, which can heat the waste heat boiler, so as to achieve the purpose of waste heat recovery.

[0031] Furthermore, the top of the heat collecting cover 2 is rotatably connected with an adjusting bolt 7. The top of the baffle 3 is fixedly provided with a connecting block 8. The connecting block 8 is threadedly connected with the adjusting bolt 7. By screwing the adjusting bolt 7, the rising or falling of the baffle 3 can be controlled. A slideway 9 is fixedly arranged on the heat collecting cover 2, and the baffle 3 is slidably arranged on the slideway 9, which can make the up - and - down sliding of the baffle 3 more stable.

[0032] In another embodiment, a hydraulic cylinder is fixedly arranged on the top of the heat collecting cover 2. The top of the baffle 3 is fixedly provided with a connecting block 8. The cylinder barrel of the hydraulic cylinder is fixedly connected with the heat collecting cover 2, and the piston rod of the hydraulic cylinder is fixedly connected with the connecting block 8. The rising or falling of the baffle 3 can be controlled by the telescopic movement of the hydraulic cylinder.

[0033] Furthermore, a filter plate 10 is provided in the water collecting tank 5. The filter plate 10 is horizontally arranged. After the cooling water drops into the water collecting tank 5, the filter plate 10 can remove impurities in the water, preventing the impurities from entering the water pump or the nozzle and causing equipment damage or blockage.

[0034] Furthermore, since the temperature below the profiled steel is also relatively high and hot air will rise, but the profiled steel will block part of the heat from rising, resulting in heat accumulation below the profiled steel and affecting the cooling speed. Therefore, a blowing air pipe 11 is also provided. The blowing air pipe 11 is located below the cooling bed body 1. A plurality of blowing holes are provided on the blowing air pipe 11, and the blowing holes face the cooling bed body 1. One end of the blowing air pipe 11 is connected to a cooling fan. The cold air can be blown out from the blowing holes of the blowing air pipe 11 to disperse the heat below the profiled steel and send it into the heat collecting cover 2, and then be taken away by the exhaust air pipe. Therefore, the cooling speed can be increased and the cooling time can be reduced.

[0035] As Figure 3 shown, furthermore, a cooling cavity 12 is provided on the top plate of the heat collecting cover 2. A coil pipe is provided in the cooling cavity 12 for waste heat recovery. Before a part of the hot air in the heat collecting cover 2 is taken away by the exhaust air pipe, it will rise and accumulate at the top of the heat collecting cover 2. In order to prevent this part of the heat from being dissipated to the outside, cooling water flows through the coil pipe in the cooling cavity 12, which can absorb this part of the heat, thereby achieving the purpose of waste heat recovery. At the same time, it can also reduce the temperature in the heat collecting cover 2 and accelerate the cooling speed.

[0036] In another embodiment, a cooling cavity 12 is provided on the top plate of the heat collecting cover 2. A water inlet pipe is connected to the top plate of the heat collecting cover 2, and the water inlet pipe is communicated with the cooling cavity 12. A plurality of through holes are provided on the lower end surface of the top plate of the heat collecting cover 2, and the through holes are communicated with the cooling cavity 12. The water inlet pipe injects cooling water into the cooling cavity 12, and the cooling water fills the cooling cavity 12, which can absorb the heat accumulated above the heat collecting cover 2. Moreover, the cooling water in the cooling cavity 12 can also drip onto the profiled steel through the through holes to cool down the profiled steel.

[0037] Furthermore, a wind collecting cover is provided in the heat collecting cover 2, and the wind collecting cover is connected to the exhaust air pipe 6.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
