[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a pickling chamber for hot-dip galvanizing of steel comprises a chamber body 1, an observation window 2 is arranged at the front of the chamber body 1, door bodies 3 are movably installed at both ends of the chamber body 1, a pickling assembly 4 is installed inside the chamber body 1, a cleaning assembly 5 is installed at the rear end of the chamber body 1, the pickling assembly 4 comprises a pickling tank 6 and a water washing tank 7, the pickling tank 6 and the water washing tank 7 are respectively installed at the bottom end of the chamber body 1, a first screw rod 8 and two sliding rods 9 are movably installed through the top end of the chamber body 1, a slider 10 is movably installed around the first screw 8 and the two sliding rods 9, a first motor 11 is installed at one end of the first screw 8, a winding drum 12 is installed at the bottom of the slider 10, a second motor 13 is installed at the front of the winding drum 12, a reel 14 is installed inside the winding drum 12 and at one end of the output shaft of the second motor 13, a chain rope 15 is wound and connected around the bottom of the winding drum 12 and around the outer periphery of the reel 14.

[0024] In this embodiment, the first screw 8 and the output shaft of the first motor 11 are arranged to rotate synchronously, and the slider 10 is arranged on the periphery of the first screw 8 and is threadedly connected. The slider 10 is driven to slide by the first screw 8 to operate the moving steel for pickling and cleaning.

[0025] In this embodiment, the middle of the two door bodies 3 are both provided with the same observation window 2, and the roller 14 is arranged to rotate synchronously with the output shaft of the second motor 13. The roller 14 is driven to rotate by the second motor 13 to adjust the lifting and lowering of the steel.

[0026] In this embodiment, one end of the chain rope 15 is fixedly connected to the roller 14, and the other end of the chain rope 15 is connected to a hook. The steel is hung by the hook at the bottom end of the chain rope 15 for pickling and cleaning in sequence.

[0027] In this embodiment, the cleaning component 5 includes an adjusting seat 16 and a filter box 21. The adjusting seat 16 is fixedly installed at the rear of the pickling tank 6, and the filter box 21 is placed inside the pickling tank 6. A second screw 17 is movably installed inside the adjusting seat 16. A third motor 18 is installed at the top of the second screw 17 and at the bottom of the adjusting seat 16. A lifting block 19 is movably installed around the second screw 17 and at the front of the adjusting seat 16. Two slots 20 are provided in the front of the lifting block 19. Two blocks 22 are fixedly installed at the top of the rear of the filter box 21. The filter box 21 is used to collect steel slag, debris and other debris dropped during the pickling process, which is convenient for subsequent cleaning.

[0028] In this embodiment, the lifting block 19 is sleeved on the outer periphery of the second screw rod 17 and is threadedly connected. The second screw rod 17 and the output shaft of the third motor 18 are synchronously rotated. The filter box 21 is lifted and lowered by the lifting block 19, which facilitates the installation and disassembly of the filter box 21.

[0029] In this embodiment, the filter box 21 is located inside the pickling tank 6 and is matched with each other. The clamping block 22 is located in the clamping slot 20 and is clamped. The clamping block 22 is clamped with the clamping slot 20, so the filter box 21 is easy to disassemble and clean the inside of the filter box 21.

[0030] It should be noted that the utility model is a pickling chamber for hot-dip galvanizing of steel. When in use, the slider 10 is first moved to the feed port at one end of the chamber body 1, and the steel is mounted on the hook at the bottom end of the chain rope 15, and then the door body 3 is closed. When pickling is performed, the first motor 11 is started to drive the first screw 8 to rotate and drive the slider 10 to slide, so that the slider 10 drives the mounted steel to move synchronously. When the steel moves to the square of the pickling tank 6, the first motor 11 is stopped, and the roller 14 is rotated by starting the second motor 13, and the chain rope 15 is extended to allow the steel to enter the pickling tank 6 for pickling. After the pickling is completed, the steel is raised, and the slider 10 continues to slide by the drive of the first motor 11. When the steel moves to the top of the water washing tank 7, the second motor 13 is driven to make the steel enter the water washing tank 7 for cleaning. After cleaning, the steel is lifted and moved to the discharge port at the other end of the chamber body 1, and the door body 3 is opened to take out the steel. Since slag, debris and other sundries may fall during the pickling process, they are collected by the filter box 21. When cleaning regularly, the third motor 18 is started to make the second screw 17 drive the lifting block 19 to slide upward, and drive the filter box 21 out of the pickling tank 6, and the filter box 21 is taken out for cleaning. When installing again, the block 22 at the rear of the filter box 21 is inserted into the slot 20, and the filter box 21 is allowed to enter the pickling tank 6 by sliding the lifting block 19 downward for collection and filtration.
