TECHNICAL FIELD
[0001] The utility model relates to steel cord production technical field, and specifically relates to based on steam heating drying phosphating line drying device. BACKGROUND
[0002] Steel cord production is related to dry drawing, electroplating, wet drawing, stranding and other processes. The stability of the product quality in the electroplating process directly affects the drawing and twisting of the wet drawing and stranding processes.
[0003] The electroplating process involves copper plating and zinc plating processes, and then brass is formed through intermediate frequency heat diffusion. Due to the high diffusion temperature, zinc oxide is easily formed on the surface of the steel wire. The zinc oxide on the surface of the steel wire needs to be removed through a phosphoric acid washing process. After phosphoric acid washing, the surface of the phosphorus needs to be washed clean.
[0004] However, a small amount of phosphorus adheres to the steel wire, and then the finished cord is obtained after drawing and plying. The rubber is adhered, and then an aging test (salt spray test) is carried out. The adhesion between the cord and the rubber is detected. The aging test results show that the adhesion of the phosphorus-containing steel wire is greater than that of the steel wire without phosphorus. That is, the cord made of phosphorus-containing steel wire can resist aging after being pressed into rubber.
[0005] Due to the characteristics of the phosphating line, some customers have the demand for the phosphating line. Therefore, it is necessary for the production line to simultaneously produce normal steel wire and phosphating line. Normal phosphoric acid washing needs to pass through a soap immersion tank, and the phosphating line cannot pass through the soap immersion tank, otherwise the surface phosphorus will be washed off.

[0026] In order to understand the technical content of the utility model more, specific embodiments are raised and the following is described with the aid of the accompanying drawings.
[0027] Combined with Figure 1 shown, the first aspect of the utility model proposes the phosphating line drying device 100 based on steam heating drying, which is arranged above the saponification tank 200 as a whole, normal steel wires need to be washed by 8 water after phosphoric acid washing, gradually reduce the concentration of phosphoric acid, until the ph value is neutral, then remove the attached phosphorus through the saponification tank 200, and the phosphating line does not pass through the saponification tank 200, and passes through above the saponification tank 200 as a whole, and the phosphating line is obtained after drying the steel wire, therefore, the production line can produce normal steel wires, and can also produce phosphating lines.
[0028] Combined with Figure 2 shown, the drying device 100 mainly comprises a support 10, a drying cylinder 20, a fan 30 and a limiting part 40, the support 10 is arranged on one side of the saponification tank 200, the drying cylinder 20 is connected to the support 10 and located above the saponification tank 200, in production, normal steel wires are washed for the last time from the saponification tank 200, and the phosphating line is dried through the drying cylinder 20 above.
[0029] Combined with Figure 2 shown, the drying cylinder 20 is provided with a drying channel 201, the drying cylinder 20 is arranged obliquely, the steel wire passes through from the low place to the high place of the drying channel 201, and the fan 30 is connected to the drying cylinder 20.
[0030] In an optional embodiment, the drying cylinder 20 is provided with a sandwich layer 22, the drying cylinder 20 is further provided with a steam inlet 23 and a steam outlet 21 connected to the sandwich layer 22, and hot steam is introduced into the sandwich layer 22 through the steam inlet 23.
[0031] The pretreatment process of steel cord production produces hot steam. In order to reduce power consumption and improve the utilization rate of hot steam, hot steam can be introduced into the interlayer 22 of the drying cylinder 20 to heat the drying cylinder 20, so that the drying channel 201 in the drying cylinder 20 reaches the preset temperature.
[0032] In this way, when the phosphating wire passes through the drying channel 201 of the drying cylinder 20, the moisture on the surface of the phosphating wire is dried by the internal heat, and the airflow blown by the fan 30 is used to improve the drying speed. The fan 30 blows from the upper part of the drying channel 201 to the lower part, that is, as shown in the figure, from the upper left to the lower right. The conveying direction of the steel wire is from the lower right to the upper left, and the relative speed of the airflow and the steel wire is large, which can improve the drying efficiency of the steel wire. Figure 2
[0033] Further, the limiting component 40 is arranged at both ends of the drying cylinder 20, so that the plurality of steel wires passing through the drying channel 201 have a predetermined spacing.
[0034] In this way, the space around each steel wire is large, and the area in contact with the airflow is large, which is beneficial to the drying of the steel wire.
[0035] Further, the limiting component 40 includes a plurality of limiting grooves, and the plurality of limiting grooves are arranged in a linear type.

[0037] As shown in Figure 2 and Figure 4 , the air outlet 31 of the fan 30 is configured as a linear groove, and the width direction of the air outlet 31 is parallel to the arrangement direction of the limiting grooves.
[0038] In this way, the airflow blown out of the air outlet 31 of the fan 30 flows along the surface of the plurality of steel wires arranged in a linear type, which improves the evaporation rate of the moisture on the surface of the steel wire and realizes the drying of the steel wire.
[0039] As shown in Figure 3 , the high end of the drying cylinder 20 is provided with a first limiting component 401, and the low end of the drying cylinder 20 is provided with a second limiting component 402, and the first limiting component 401 and the second limiting component 402 have the same structure.

[0042] Specifically, a plurality of limiting posts 42 are arranged on the bottom plate of the mounting plate 41 at equal intervals, and a cross bar 43 is further connected to the hook-shaped structures on both sides of the bottom plate of the mounting plate 41, the cross bar 43 being perpendicular to the limiting posts 42, and the limiting slots are formed by the cross bar 43 and the limiting posts 42 arranged in a cross and vertical manner, so that a plurality of limiting slots are formed between the cross bar 43 and the plurality of limiting posts 42, and each steel wire passes through a limiting slot, and the steel wires are separated by the limiting slots.
[0043] Further, the cross bar 43 is connected to the mounting plate 41 by a height adjusting component 44, so that the cross bar 43 can move in the height direction of the limiting posts 42.
[0044] In an optional embodiment, the cross bar 43 and the limiting posts 42 are connected by a bearing. Figure 3 As shown, the limiting posts 42 are provided with screw rods at both ends, the screw rods being parallel to the limiting posts 42, and the screw rods being connected to the mounting plate 41 by nuts.
[0045] In this way, the height adjusting component 44 is composed of the nuts and the screw rods, and when the nuts are rotated to different positions during height adjustment, the relative positions of the screw rods and the mounting plate 41 change, that is, the height of the cross bar 43 changes.
[0046] In a preferred embodiment, the cross bar 43 and the limiting posts 42 can rotate relative to the steel wires.
[0047] In an optional embodiment, the cross bar 43 and the connecting structures at both ends are connected by a bearing, and the limiting posts 42 and the mounting plate 41 are also connected by a bearing, so that the cross bar 43 and the limiting posts 42 can rotate freely.
