A coil spray lubrication device with demisting function

Abstract

This utility model discloses a coil spray lubrication device with demisting function, relating to the field of coil transportation. The coil is suspended from a C-shaped hanger, one end of which has a sliding inner cover (including inner and outer ring spray mechanisms, equipped with dual-flow nozzles), and the other end has a fixed sealing cover and a sliding outer cover. The fixed sealing cover is connected to a negative pressure demisting mechanism including an air duct, a vertical cyclone separator, and a centrifugal fan. The inner and outer covers move towards the C-shaped hanger and close, placing the coil in a closed space. The three-dimensional spraying mechanism evenly sprays atomized lubricating fluid onto the inner and outer rings of the coil, while the negative pressure demisting mechanism creates negative pressure to extract the floating atomized lubricating fluid. After separation, the liquid can be recycled. The device combines semi-closed sealing with negative pressure demisting to prevent lubricating fluid diffusion, balancing lubrication protection and environmental protection, reducing costs, adapting to existing equipment, and requiring low modification difficulty.

Description

Technical Field

[0001] This utility model relates to coil transportation, specifically to a coil spray lubrication device with defogging function. Background Technology

[0002] After the wire is coiled, it needs to be bundled before being delivered to the user. During bundling, the coils are subjected to pressure, which can cause defects such as crushing marks and surface abrasions. These surface problems directly affect the quality of the coils leaving the factory. To solve this problem, a protective coating of lubricant can be applied to the surface of the coils. However, using this method also requires addressing environmental and safety issues, such as preventing the lubricant from being released into the air. Utility Model Content

[0003] This invention provides a coil spray lubrication device with defogging function, wherein the coil is suspended on a C-shaped hanger.

[0004] A sliding inner cover is provided at one end of the C-shaped lifting device. The top of the inner cover has strip-shaped openings distributed along the sliding direction. The C-shaped lifting device passes through the strip-shaped openings from top to bottom, so that the coil is located inside the inner cover.

[0005] The inner cover is equipped with a three-dimensional lubricant spraying mechanism, which includes an inner ring spraying mechanism and an outer ring spraying mechanism. The inner ring spraying mechanism and the outer ring spraying mechanism are connected to the lubricant supply system. The inner ring spraying mechanism is equipped with a central tube that is axially fixed inside the inner cover, and multiple first spray nozzles are arranged around the central tube. The outer ring spraying mechanism is equipped with multiple second spray nozzles arranged circumferentially on the inner wall of the inner cover.

[0006] A fixed sealing cover and an outer cover are provided at the other end of the C-shaped hanger. The fixed sealing cover is fixed to the ground, and the outer cover is slidably installed inside the fixed sealing cover. The fixed sealing cover is connected to a negative pressure demisting mechanism, which includes a duct, a steam-water separator, and a centrifugal fan. One end of the duct is connected to the fixed sealing cover, and the other end is connected to the steam-water separator. The steam-water separator is connected to the centrifugal fan.

[0007] The inner and outer covers move simultaneously toward the C-shaped lifting device, causing the coil to enter the inner cover and the inner cover to enter the outer cover. A three-dimensional lubricant spraying mechanism sprays atomized lubricant onto the inner and outer rings of the coil, and a negative pressure defogging mechanism creates negative pressure in the inner cover, outer cover, and fixed sealing cover to extract the atomized lubricant floating in the inner and outer covers.

[0008] Furthermore, the steam-water separator is a vertical cyclone separator. The steam-water separator is equipped with an exhaust port connected to the air inlet of a centrifugal fan, and a drain port at the bottom for discharging the separated liquid.

[0009] Furthermore, the inner walls of the inner cover, outer cover, and fixed sealing cover are all coated with a corrosion-resistant coating.

[0010] Furthermore, a sealing door is provided at the end of the fixed sealing cover away from the inner cover.

[0011] Furthermore, the inner cover, outer cover, and fixed sealing cover are all U-shaped metal covers;

[0012] The ground is equipped with a first ground rail and a second ground rail. The inner cover and the outer cover are slidably installed on the first ground rail and the second ground rail respectively through a roller drive mechanism.

[0013] Furthermore, both the first and second spray nozzles are dual-flow nozzles.

[0014] This utility model discloses a coil spray lubrication device with demisting function, the technical advantages of which are reflected in the following aspects:

[0015] 1. A semi-enclosed arched sealing cover is used to form a physical isolation barrier. Combined with a negative pressure demisting system, a negative pressure environment is created, which can effectively adsorb the mist-like lubricating liquid generated during spraying operations, prevent the mist-like lubricating liquid from spreading into the workshop, improve the air quality of the working environment, and meet the strict environmental protection requirements of the steel industry.

[0016] 2. Gas-liquid separation is achieved through a vertical cyclone separator. The separated liquid is recovered through the drain outlet and can be recycled back into the liquid supply system, reducing lubricant waste, lowering production costs, and avoiding secondary pollution to the environment from waste liquid discharge.

[0017] 3. The interior of the sealing cover is divided into a spraying operation area and a negative pressure demisting area. The spraying operation area is positioned in front to ensure that the atomized lubricant adheres to the surface of the coil first, preventing it from being sucked away before it adheres. Combined with the three-dimensional spraying system (central spray pipe + outer spray pipe), it achieves uniform spraying of the inner and outer rings of the coil, taking into account both "demisting" and "lubrication" functions without sacrificing the product's protective quality.

[0018] 4. The entire device is seamlessly integrated with the coil spray lubrication system (mobile trolley, ground rail, three-dimensional spray system), eliminating the need for large-scale modifications to the original equipment, reducing modification costs and implementation difficulty, and demonstrating good engineering application feasibility.

[0032] In an optional embodiment, the fixed sealing cover 5 is provided with a sealing door at the end away from the inner cover 4, which facilitates personnel to enter the equipment inside the fixed sealing cover 5 for maintenance and repair.
