Description

Technical Field

[0001] The utility model relates to the technical field of zinc pots, in particular to a slag blocking device. Background Art

[0002] When running thin zinc-coated strip at high speed, the air knife has extremely high wind pressure, which causes serious splashing of zinc liquid, which can easily burn the surrounding operators. In addition, the flying zinc slag cannot be reused, resulting in huge waste. According to statistics, the waste of zinc liquid caused by zinc slag splashing can reach about 0.5 tons; therefore, a slag blocking device is needed.

[0003] Patent No. CN 206428310U discloses a zinc pot slag blocking device and a zinc pot. The slag blocking device includes: a baffle, the bottom end of which is hinged to the upper surface of the zinc pot rim through a first hinge axis; the setting direction of the first hinge axis is parallel to the pot rim; the first hinge axis is set at the inner end of the upper surface of the pot rim, and the inner end is the end close to the zinc liquid in the zinc pot; a rotating support rod, the bottom end of which is hinged to the upper surface of the pot rim through a second hinge axis, and the top end is in contact with the vertical surface of the baffle; the setting direction of the second hinge axis is parallel to the pot rim; the second hinge axis is set on the outside of the first hinge axis; a stopper, which is set on the vertical surface of the baffle facing the rotating support rod, and when the baffle is in a vertical position, the stopper abuts against the top of the rotating support rod. The zinc pot slag blocking device provided by the utility model is lifted when the air knife air pressure is too high, and can block the splashing zinc liquid and rebound it into the zinc pot. When doing pot maintenance and slag removal, the baffle can be laid flat to facilitate maintenance, increase safety and reduce waste without causing any inconvenience.

[0004] The existing slag blocking device has the following disadvantages: 1. It cannot realize automatic control of the up and down movement of the slag blocking plate, and the degree of automation is low. Therefore, we propose a zinc pot slag blocking device. Utility Model Content

[0005] The main purpose of the utility model is to provide a zinc pot slag blocking device, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A zinc pot slag stop device comprises a sliding hole, an outer frame, a rectangular slag stop plate and an inner extending stop bar. Servo motors are mounted on both ends of the outer frame through mounting seats, and the output shaft of the servo motor is connected to a lead screw. A lead screw is sleeved on the lead screw. A rectangular slag stop plate is connected to the lead screw through a connecting block, and an inner extending stop bar is welded to the inner side of the top end of the rectangular slag stop plate. Fixed blocks are welded at the corners on both sides of the outer frame, and adjusting bolts are mounted on the fixed blocks through bolt holes.

[0008] Furthermore, a PLC controller is installed on one side of the outer frame by screws and the output end of the PLC controller is electrically connected to the input end of the servo motor through a wire. The PLC controller is used to control the forward and reverse rotation and start and stop of the servo motor to automatically control the up and down movement of the rectangular slag baffle, with a high degree of automation.

[0009] Furthermore, a sliding hole is formed at one end of the screw rod and the connecting block is located in the sliding hole.

[0010] Furthermore, an end plate is welded to the top end of the sliding hole and the top end of the screw rod is connected to the end plate via a bearing.

[0011] Furthermore, the bottom end of the adjusting bolt is connected to a support plate through a bearing. Loosening the adjusting bolt drives the support plate to move up and down, making it easy to move the outer frame to a specified height for use, thereby meeting different usage requirements.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The utility model provides a zinc pot slag blocking device, which sleeves an outer frame and a rectangular slag blocking plate on the outside of the zinc pot. Loosening the adjusting bolt drives the supporting pad to move up and down, so that the outer frame can be moved to a specified height for use to meet different usage requirements. A servo motor is used to drive the screw rod to rotate. Since the wire block is limited in the sliding hole by the connecting block, the rectangular slag blocking plate is driven to move upward. When the air knife pressure is too high, it is lifted up to block the splashed zinc liquid and rebound it into the zinc pot.

[0014] 2. The utility model is a zinc pot slag blocking device, which uses a PLC controller to control the forward and reverse rotation and start and stop of the servo motor to automatically control the up and down movement of the rectangular slag blocking plate. It has a high degree of automation and is suitable for wide promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-3 As shown, a zinc pot slag blocking device includes a sliding hole 3, an outer frame 6, a rectangular slag blocking plate 7 and an inner extending blocking bar 5. Servo motors 13 are installed at both ends of the outer frame 6 through mounting seats, and the output shaft of the servo motor 13 is connected to the screw rod 2. A wire block 14 is sleeved on the screw rod 2. The wire block 14 is connected to the rectangular slag blocking plate 7 through a connecting block 1, and the inner extending blocking bar 5 is welded to the inner side of the top of the rectangular slag blocking plate 7. Fixed blocks 9 are welded at the corners on both sides of the outer frame 6, and adjusting bolts 8 are installed on the fixed block 9 through bolt holes.

[0021] A PLC controller 12 is mounted on one side of the outer frame 6 by screws, and an output end of the PLC controller 12 is electrically connected to an input end of the servo motor 13 by a wire.

[0022] In this embodiment, Figure 1 As shown, the PLC controller 12 is used to control the forward and reverse rotation and start and stop of the servo motor 13 to automatically control the up and down movement of the rectangular slag blocking plate 7, with a high degree of automation.

[0023] A sliding hole 3 is formed at one end of the screw rod 2 and the connecting block 1 is located in the sliding hole 3 .

[0024] In this embodiment, Figure 1 As shown, since the wire block 14 is limited in the sliding hole 3 by the connecting block 1, the rectangular slag blocking plate 7 is driven to move upward.

[0025] The top end of the sliding hole 3 is welded with an end plate 4 and the top end of the screw rod 2 is connected to the end plate 4 via a bearing.

[0026] In this embodiment, Figure 1 As shown, the screw rod 2 is allowed to rotate stably.

[0027] The bottom end of the adjusting bolt 8 is connected to a supporting plate 11 via a bearing 10 .

[0028] In this embodiment, Figure 1 As shown, loosening the adjusting bolt 8 drives the supporting pad 11 to move up and down, so as to facilitate moving the outer frame 6 to a specified height for use to meet different usage requirements.

[0029] It should be noted that the utility model is a zinc pot slag blocking device. When working, the outer frame 6 and the rectangular slag blocking plate 7 are sleeved on the outside of the zinc pot, and the adjusting bolt 8 is loosened to drive the support pad 11 to move up and down, so that the outer frame 6 can be moved to a specified height for use to meet different usage requirements. The servo motor 13 is used to drive the screw rod 2 to rotate. Since the wire block 14 is limited in the slide hole 3 by the connecting block 1, the rectangular slag blocking plate 7 is driven to move upward. When the air knife pressure is too high, it is lifted up to block the splashed zinc liquid and rebound it into the zinc pot. The PLC controller 12 is used to control the forward and reverse rotation and start and stop of the servo motor 13 to realize automatic control of the up and down movement of the rectangular slag blocking plate 7. It has a high degree of automation and is suitable for wide promotion and use.
