Technical Field

[0001] The present application relates to the technical field of stainless steel bar processing, and in particular to a high-strength and toughness stainless steel bar drying device. Background Art

[0002] With the continuous development of modern industrial technology, high-strength and tough stainless steel bars have been widely used in aerospace, automobile manufacturing, petrochemical, medical equipment and other fields. This type of material not only has excellent mechanical properties and corrosion resistance, but also performs well in harsh environments such as high temperature and high pressure, becoming one of the key materials to promote the development of modern industry.

[0003] However, in the production process of high-strength and tough stainless steel bars, drying is a crucial step. Bars often need to go through multiple processes in the production process, including rolling, stretching, heat treatment, etc. After these processes are completed, impurities such as moisture and oil are often attached to the surface of the bars. These impurities not only affect the appearance quality of the bars, but more importantly, they may have a potential impact on their performance, reducing their service life and safety.

[0004] Traditional methods of drying stainless steel bars often rely on simple hot air drying technology. In this process, the stainless steel bars are usually placed on a drying rack and placed inside a drying chamber for drying. However, this drying method has a significant drawback: the contact surface between the stainless steel bars and the drying rack is often difficult to fully contact the hot air. This contact surface limitation leads to uneven heat distribution during the drying process, which affects the drying effect of the stainless steel bars. Utility Model Content

[0036] The guide assembly includes a guide slider 10 symmetrically fixedly connected to one end of the synchronous push rod 7, and a guide slot 11 adapted to the guide slider 10 is provided on one side of the drying rack 3;

[0037] In addition, the drying component includes a dehumidification chamber 12 arranged inside the drying chamber 1, the top of the dehumidification chamber 12 is connected to the drying chamber 2, and one end of the drying chamber 1 is evenly provided with multiple heating pipes 13 connecting the drying chamber 2 and the dehumidification chamber 12, and the interior of the heating pipe 13 is fixedly connected with an electric heating wire 14, and the interior of the heating pipe 13 is fixedly connected with an exhaust fan 15.

[0038] When in use, first place the stainless steel bar between two adjacent support rollers 5, then push the drying rack 3 to drive the support wheel 4 to roll along the ground, and at the same time make the drying rack 3 drive the stainless steel bar to move into the drying bin 2, and then start the electric heating wire 14 and the exhaust fan 15, so that the exhaust fan 15 draws the air inside the drying bin 2 into the dehumidification bin 12, and then discharges it into the drying bin 2 through the heating pipe 13, and when the air is drawn through the heating pipe 13, the air contacts the electric heating wire 14 for heat exchange, thereby increasing the temperature of the air passing through the heating pipe 13, and then the heated air is discharged into the drying bin 2 for circulation, so as to realize the drying of the stainless steel bar on the top of the support roller 5;

[0039] At the same time, by starting the guide slot 11, the synchronous push rod 7 drives the guide slider 10 to move back and forth along the length direction of the guide slot 11, and the synchronous push rod 7 drives the driving rack 8 to form a reciprocating meshing with the driving gear 9, so that the driving gear 9 drives the supporting roller 5 to lift the stainless steel bar and rotate reciprocatingly, and the two adjacent supporting rollers 5 drive the stainless steel bar to rotate reciprocatingly, so that the contact surface between the stainless steel bar and the supporting roller 5 is flipped to contact with the air inside the drying bin 2, and at the same time, the heated air circulates inside the drying bin 2 to comprehensively dry the stainless steel bar, thereby effectively reducing the problem that the contact surface between the stainless steel bar and the supporting roller 5 is difficult to fully contact with the hot air, thereby improving the drying effect of the device.

[0040] Reference Figure 2 and Figure 4 A plurality of polyacrylic acid dehumidification filter plates 16 are evenly and fixedly connected inside the dehumidification chamber 12, and two adjacent polyacrylic acid dehumidification filter plates 16 are staggered to form a curved air duct.

[0041] During use, when the exhaust fan 15 is started to drive the air to circulate between the drying chamber 2 and the dehumidification chamber 12, the air moves along the curved air duct formed between the multiple polyacrylic acid dehumidification filter plates 16 when passing through the dehumidification chamber 12, and forms full contact with the polyacrylic acid dehumidification filter plates 16. At the same time, the moisture carried in the air is filtered and absorbed by the polyacrylic acid dehumidification filter plates 16, thereby effectively reducing the moisture content in the air and further improving the drying effect of the device.

[0042] Reference Figure 3 and Figure 5 , the outer fixed sleeve of the supporting roller 5 is provided with a rubber sleeve 17;

[0043] Two groups of rubber strips 18 are symmetrically fixedly connected to the periphery of the rubber sleeve 17 .

[0044] When in use, when the traction stainless steel bar is placed on the top of two adjacent support rollers 5, the support rollers 5 form a flexible contact with the stainless steel bar through the rubber sleeves 17, thereby effectively reducing the wear between the support rollers 5 and the stainless steel bar and extending the service life of the device;

[0045] Then, when the support roller 5 is driven to drive the stainless steel bar to rotate, the support roller 5 drives the rubber sleeve 17 to cooperate with the rubber strip 18 to form a conflict with the surface of the stainless steel bar, and pushes the stainless steel bar to rotate, thereby effectively improving the friction between the rubber sleeve 17 and the stainless steel bar, and improving the rotation efficiency of the stainless steel bar.

[0046] Reference Figure 1 and Figure 2 A heat-insulating rock wool board 19 is fixedly connected to the periphery of the drying chamber 1 .

[0047] When in use, the heat exchange between the inside and outside of the drying chamber 1 is reduced by setting the heat insulating rock wool board 19, thereby reducing the heat consumption inside the drying chamber 1 and improving the heat utilization rate inside the drying chamber 1.

[0048] Reference Figure 2 and Figure 3 The surfaces of the driving rack 8 and the driving gear 9 are coated with a silicone coating.

[0049] When in use, by coating the surfaces of the drive rack 8 and the drive gear 9 with a silicone coating, an anti-corrosion protective layer is formed on the surfaces of the drive rack 8 and the drive gear 9, thereby effectively reducing the wear and tear of the drive rack 8 and the drive gear 9 caused by rust and extending the service life of the device.

[0051] Then, the exhaust fan 15 is started to drive the air to circulate between the drying chamber 2 and the dehumidification chamber 12, so that the air moves along the curved air duct formed between the multiple polyacrylic acid dehumidification filter plates 16 when passing through the dehumidification chamber 12, and forms full contact with the polyacrylic acid dehumidification filter plates 16, and at the same time, the moisture carried in the air is filtered and absorbed by the polyacrylic acid dehumidification filter plates 16, thereby effectively reducing the moisture content in the air;

[0052] Then, by starting the guide slot 11, the synchronous push rod 7 drives the guide slider 10 to move back and forth along the length direction of the guide slot 11, and the synchronous push rod 7 drives the driving rack 8 to form a reciprocating meshing with the driving gear 9, so that the driving gear 9 drives the supporting roller 5 to lift the stainless steel bar and rotate reciprocatingly, and the two adjacent supporting rollers 5 drive the stainless steel bar to rotate reciprocatingly, so that the contact surface between the stainless steel bar and the supporting roller 5 is flipped to contact with the air inside the drying bin 2, and at the same time, the heated air circulates inside the drying bin 2 to comprehensively dry the stainless steel bar.
