Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, in particular to a drying device for a phosphating line based on electric heating and drying. Background Art

[0002] Steel cord production involves multiple processes including dry drawing, electroplating, wet drawing, and stranding. The stability of product quality in the electroplating process will directly affect the drawing and twisting of the wet drawing and stranding processes.

[0003] The electroplating process involves copper plating and zinc plating processes, which are then diffused through medium-frequency heat to form brass. Due to the high diffusion temperature, zinc oxide is easily formed on the surface of the steel wire. It is necessary to use a phosphoric acid washing process to remove the zinc oxide on the surface of the steel wire. After phosphoric acid washing, it is necessary to wash with water to rinse off the phosphorus on the surface.

[0004] However, a small amount of phosphorus adheres to the steel wire. After drawing and plying, the resulting finished cord is bonded to the rubber. Aging tests (salt spray tests) are then conducted to measure the bond strength between the cord and the rubber. The aging test results show that the bond strength of the phosphorus-containing steel wire is greater than that of the non-phosphorus-containing steel wire. This means that cords made with phosphorus-containing steel wire are more resistant to aging when pressed into rubber.

[0005] Due to the characteristics of phosphating lines, some customers have demand for phosphating lines. Therefore, the production line must be able to produce normal steel wire and phosphating lines at the same time. Normal phosphoric acid washing requires passing through a soap immersion tank, while phosphating lines cannot pass through a soap immersion tank, otherwise the phosphorus on the surface will be washed away. How to solve this problem is what people hope to solve. Utility Model Content

[0027] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0028] Combine Figure 1 As shown, the first aspect of the present invention proposes a phosphating line drying device 100 based on electric heating and drying, which is arranged above the saponification tank 200. Normal steel wire needs to be rinsed with water 8 times after being washed with phosphoric acid to gradually reduce the phosphoric acid concentration until the pH value is neutral, and then pass through the saponification tank 200 to remove the attached phosphorus. The phosphating line does not pass through the saponification tank 200, but passes through the top of the saponification tank 200 as a whole. After the steel wire is dried, the phosphating line is obtained. Therefore, the production line can produce normal steel wire and phosphating line at the same time.

[0029] Combine Figure 2 As shown, the drying device 100 includes a bracket 10, a drying box 20, and a blower 30. The bracket 10 is positioned on one side of the soap tank 200. The drying box 20 is connected to the bracket 10 and positioned above the soap tank 200. A wiring channel 201 is provided within the drying box 20, along with an electric heating element 22. The blower 30 is connected to the drying box 20 and is used to blow air into the drying box 20. The airflow generated by the blower 30 passes through the electric heating element 22 and the wiring channel 201.

[0030] In this way, when the steel wire passes through the wiring channel 201, the blowing component 30 draws external air into the wiring channel 201, and the air flow is heated by the electric heating component 22. The hot air flow blown out evaporates the moisture on the surface of the steel wire when passing through the surface of the steel wire, thereby drying the steel wire.

[0031] Furthermore, the wiring channel 201 is arranged at an angle, and the steel wire enters from the wire inlet 203 of the wiring channel 201 and exits from the wire outlet 202 , and the wire inlet 203 is lower than the height of the wire outlet 202 .

[0032] In this way, when the air flow passes through the surface of the steel wire, the water vapor on the surface of the steel wire gathers and easily drips downwards, which can increase the drying speed of the steel wire.

[0033] In an optional embodiment, a partition 23 is provided inside the drying box 20, an electric heating component 22 is provided on the first side of the partition 23, and a wiring channel 201 is provided on the second side. The blowing component 30 is installed on the outer wall of the drying box 20, and air is extracted from the outside of the drying box 20 so that the airflow passes through the electric heating component 22 and the wiring channel 201 in sequence.

[0034] In this way, the space inside the drying box 20 is divided into two parts by the partition 23. The first part is the space where the electric heating component 22 is located, and the second part is the wiring channel 201. The space of the wiring channel 201 is cleaner and free of other debris. The steel wire will not come into contact with other structures when passing through the wiring channel 201.

[0035] In an optional embodiment, the electric heating component 22 includes a plurality of heating wire structures, and the plurality of heating wire structures are arranged at equal intervals along the air flow path.

[0036] In this way, the air flow is heated when passing through the electric heating wire to form a hot air flow, which can increase the drying speed of the steel wire.

[0037] Combine Figure 3 As shown, the blowing component 30 includes a fan 31 , and the drying box 20 is provided with an air inlet slot 21 corresponding to the position of the fan 31 . The fan 31 and the air inlet slot 21 are both located on the side of the partition 23 away from the wiring channel 201 .

[0038] In this way, when the fan 31 rotates, the air sucked in enters the air inlet slot 21 and first needs to pass through the partition 23 or the channel formed by the partition 23 before entering the wiring channel 201. During this process, the air flow can be heated.

[0039] In an optional embodiment, if Figure 3 As shown, a plurality of ventilation holes 231 are provided on the partition 23 to connect the space on the first side and the space on the second side of the partition 23.

[0040] In this way, the air flow can enter the wiring channel 201 through the ventilation hole 231, and since the partition 23 and the wiring direction of the steel wire are parallel, the wind blown out from the ventilation hole 231 can blow vertically to the surface of the steel wire, causing the water droplets accumulated on the surface to drip downward.

[0041] Combine Figure 3 As shown, along the length direction of the wiring channel 201 , air guide plates 24 are provided at the first end and the second end of the partition 23 , and a gap is provided between the air guide plates 24 and the partition 23 .

[0042] In this way, most of the airflow passes through multiple heating wires from above the partition 23 and reaches the gap between the air guide plate 24 and the partition 23, and is blown out from the gap into the wiring channel 201 to dry the steel wire in the wiring channel 201.

[0043] Optionally, the air guide plate 24 is configured as an arc plate, and the arc surface of the air guide plate 24 guides the airflow parallel to the routing direction of the steel wire in the routing channel 201 .

[0044] In this way, the airflow passing through the air guide plate 24 is guided to blow the steel wire along the direction of the steel wire, which is beneficial to increase the contact time between the airflow and the steel wire, and dry the moisture on the surface of the steel wire faster.

[0045] In an optional embodiment, the drying box 20 is provided with an insulating interlayer 25, which is filled with an insulating layer. The insulating interlayer 25 can increase the heat preservation capacity of the drying box 20 and reduce heat loss, mainly for the purpose of reducing the energy consumption of the electric heating structure. The insulating interlayer 25 can be filled with polyurethane foam material.

[0046] In the above embodiment, in order to flexibly adjust the height of the drying box 20, the bracket 10 includes a first support rod 11 and a second support rod 12. The second support rod 12 is detachably connected to the top of the first support rod 11, so that the height of the bracket 10 can be changed.

[0047] Specifically, a plurality of insertion holes are provided on the outer walls of the first support rod 11 and the second support rod 12 . By using a pin to pass through the insertion holes at different positions of the first support rod 11 and the second support rod 12 , the overall length of the bracket 10 can be changed.

[0048] Furthermore, the second support rod 12 is hingedly connected to the bracket 10. In this way, when the lengths of the front and rear brackets 10 are adjusted to different lengths, the drying box 20 can be adjusted to different inclination angles, which can flexibly cope with the installation environment on site.

[0049] In combination with the above embodiments, the utility model dries the phosphating line by means of a drying box arranged above the saponification tank, which requires little modification to the original site and enables the production line to simultaneously produce normal steel wire and the phosphating line to meet different production needs. The drying box has an electric heating structure and a wiring channel. The steel wire passes through the drying box through the wiring channel. The electric heating structure heats the airflow entering the wiring channel. By making the hot air contact with the steel wire in parallel, the steel wire can be dried faster, thereby reducing drying energy consumption.

[0050] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
