Description

Technical Field

[0001] This utility model relates to the steel industry, specifically to a demisting device for a coil spray lubrication system. Background Technology

[0002] After the wire is coiled, it needs to be bundled before being delivered to the user. During the bundling process, the coils are subjected to pressure, which can cause defects such as crushing marks and surface abrasions. These surface defects will affect the user's experience. To solve this problem, a protective measure can be taken by spraying lubricant onto the surface of the coils.

[0003] During the spray lubrication process of coiled coils, the high atomization degree of the nozzle and the high surface temperature of the coil cause the lubricant to vaporize rapidly, resulting in a large amount of water vapor and mist spreading into the air during the spray lubrication process, which affects the surrounding environment. Utility Model Content

[0004] This utility model provides a demisting device for a coil spray lubrication system, which absorbs and collects the water vapor and mist generated during the spray lubrication process, effectively preventing the water vapor and mist from spreading into the surrounding environment, thereby improving the quality of the working environment and meeting environmental protection requirements. To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An arched sealing cover, a semi-enclosed arched sealing cover fixed to the ground, contains a coil inside the arched sealing cover. The inner area of ​​the arched sealing cover near the opening is a spray operation area for accommodating the coil and allowing a mobile trolley to enter, while the other end is a negative pressure demisting area. The arched sealing cover near the spray operation area has an opening for the mobile trolley to enter and exit.

[0007] The negative pressure demisting system includes a duct, a steam-water separator, and a centrifugal fan. One end of the duct is connected to the negative pressure demisting area, and the other end is connected to the steam-water separator, which is connected to the centrifugal fan.

[0008] Furthermore, the sidewalls or top surface of the negative pressure demisting zone are equipped with flanges that are sealed to the air ducts.

[0009] 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.

[0010] Furthermore, the sides of the arched sealing cover are equipped with transparent observation windows located in the spray operation area and the negative pressure demisting area, respectively.

[0011] Furthermore, a centrifugal fan silencer is installed at the air outlet of the centrifugal fan.

[0012] Furthermore, the arched sealing cover is a metal cover, and a corrosion-resistant coating is provided inside the arched sealing cover.

[0013] Furthermore, the three-dimensional spray system includes a central spray pipe installed on a mobile trolley and an outer spray pipe circumferentially disposed on the inner wall of an arched sealing cover, which is coiled and fixed between the central spray pipe and the outer spray pipe.

[0014] Furthermore, the arched sealing cover has an openable sealing door at one end near the negative pressure demisting zone.

[0015] 1. This utility model isolates the spray operation area through a semi-enclosed arched sealing cover, and forms a negative pressure defogging system to effectively adsorb water vapor and mist generated by the spray.

[0017] 3. The arched sealing cover is made of metal with a corrosion-resistant coating on the inner wall, which can withstand the high temperature of coiling and the erosion of lubricating fluid, extend the service life of the equipment, and meet the long-term industrial operation needs of the steel industry.

[0018] 4. The sealed cover has an internal partition design (spraying area in front, negative pressure demisting area in the back) to prevent the atomized lubricant from being sucked away before it adheres to the coil.

The three-dimensional spray system 120 is mounted on the mobile trolley 110 and connected to the liquid supply system. A ground track is provided for the mobile trolley 110 to slide on. It should be noted that the applicant has filed a separate patent application for the coil spray lubrication system 100, and it will not be described in detail in this application.

[0024] The defogging device 200 of this utility model includes an arched sealing cover 210 and a negative pressure defogging system 220. The structure of the arched sealing cover 210 and the negative pressure defogging system 220 will be further described below.

[0025] In an optional embodiment, a semi-enclosed arched sealing cover 210 is fixed to the ground, with one end of a ground rail extending into the arched sealing cover 210. The arched sealing cover 210 has a certain length, which must be greater than the axial length of the coil. The inner area of ​​the arched sealing cover, near the opening, serves as a spraying area to accommodate the coil 1 and allow a mobile trolley to enter; the other end is a negative pressure demisting area. This design is adopted to prevent the atomized droplets from being sucked away by the negative pressure before adhering to the coil surface during spraying, thus ensuring the effective coverage of the lubricant spray on the inner and outer surfaces of the coil. An opening for the mobile trolley 110 to enter and exit is provided on one side of the arched sealing cover 210, and the mobile trolley 110 drives along the ground rail into the spraying area of ​​the arched sealing cover 210. An openable sealing door 212 is provided at the end of the arched sealing cover 210 near the negative pressure demisting area.

[0026] The negative pressure demisting system 220 includes a duct 221, a steam-water separator 222, and a centrifugal fan 223. One end of the duct 221 is connected to the arched sealing cover 210, and the other end is connected to the steam-water separator 222. The steam-water separator 222 is connected to the centrifugal fan 223.

[0027] In an optional embodiment, the sidewall or top surface of the arched sealing cover 210 is provided with a flange ring 211 that is sealed to the air duct 221.

[0028] In an optional embodiment, the steam-water separator 222 is a vertical cyclone separator. The steam-water separator 222 is provided with an exhaust port connected to the air inlet of the centrifugal fan 223, and a drain port at the bottom for discharging the separated liquid.

[0029] In an optional embodiment, the arched sealing cover 210 has transparent observation windows on its sides located in the spray operation area and the negative pressure demisting area, respectively, for observing the spray operation and demisting status.

[0030] In an optional embodiment, a centrifugal fan silencer is installed at the outlet of the centrifugal fan 223 to reduce the aerodynamic noise at the outlet of the centrifugal fan 223.

[0031] In an alternative embodiment, the arched sealing cover is a metal cover with a corrosion-resistant coating inside.

[0032] In an optional embodiment, the three-dimensional spray system 120 includes a central spray pipe 121 mounted on a mobile trolley and an outer spray pipe 122 circumferentially disposed within the inner wall of an arched sealing cover. A coil 1 is fixedly disposed between the central spray pipe and the outer spray pipe (the coil 1 can be removed later using equipment; the specific removal method is prior art and will not be described here). The movement of the mobile trolley causes the central spray pipe to extend into the interior of the coil. During spraying operations, the central spray pipe and the outer spray pipe simultaneously spray a mist of lubricating fluid onto the inner and outer surfaces of the coil.

[0033] The working process of this utility model is as follows:

[0034] 1. Preparation stage: The mobile trolley 110 transports the coiled coil along the ground rail into the spraying area of ​​the arched sealing cover 210. The coiled coil inside the arched sealing cover is located between the central spray pipe 121 (mounted on the trolley 110) and the outer spray pipe 122 (circled around the inner wall of the sealing cover 210). The opening end of the sealing cover 210 allows the trolley 110 to enter and exit, and the negative pressure demisting area is located at the rear end.

[0035] 2. Spray Lubrication Stage: Activate the three-dimensional spray system 120 and the liquid supply system. The central spray pipe 121 extends into the inner ring of the coil, and the outer spray pipe 122 is aligned with the outer ring, simultaneously spraying out atomized lubricating liquid to evenly coat the inner and outer surfaces of the coil. During the spraying process, the lubricating liquid atomizes and partially vaporizes to produce water vapor and mist.

[0036] 3. Demisting and collection stage: The negative pressure demisting system 220 is started, and the centrifugal fan 223 generates negative pressure. The mist and water vapor are adsorbed from the negative pressure demisting zone through the air duct 221. The mist enters the steam-water separator 222, the liquid is discharged from the drain outlet at the bottom of the separator, and the purified gas is sent into the fan 223 from the exhaust outlet at the top.

[0037] 4. Gas Exhaust Stage: Purified gas is discharged via centrifugal fan 223, and a silencer at the outlet reduces noise. The entire process is semi-enclosed to prevent fog diffusion, and a transparent observation window monitors the operation and defogging status in real time; after completion, the trolley 110 exits.
