[0034] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Embodiment 1:

[0037] like Figures 1 to 5 As shown, this embodiment proposes a thyristor medium frequency furnace slag removal mechanism, including a mounting plate 1, a turntable 2, a drive assembly 3, a reciprocating mechanism 4, a positioning assembly 5, a movable hole 8, a baffle 10, and a slag gathering rod 11 arranged inside the movable hole 8 to move the waste slag to the middle of the medium frequency furnace intersection for gathering.

[0038] Among them, the mounting plate 1 is supported on the furnace mouth of the medium frequency furnace through support rods 7 installed at the four corners of the lower end. A circular rotating hole 6 is opened in the middle position of the mounting plate 1, and a circular clamping ring 13 is fixedly connected to the inner wall of the rotating hole 6. A turntable 2 is arranged inside the rotating hole 6, and a clamping groove 14 used for matching the clamping ring 13 is opened on the outer edge of the turntable 2. The turntable 2 is clamped by the clamping ring 13 and the clamping groove 14, so that the turntable 2 can only rotate inside the rotating hole 6. A long movable hole 8 is opened on the upper side of the turntable 2, and a vertical long rod is arranged inside the movable hole 8. The long rod reciprocates up and down, and while the long rod moves up and down, the bottom end swings on both sides inside the movable hole 8 along the direction of the movable hole 8, so that the slag at the furnace mouth of the medium frequency furnace is gathered to the middle to form a slag gathering rod 11.

[0039] In order to enable the slag gathering rod 11 to automatically reciprocate up and down, a hinge support 9 is fixedly connected to one side of the outer side of the movable hole 8 at the upper end of the turntable 2, and a connecting rod 301 is hinged to the upper front end of the hinge support 9. The connecting rod 301 connects the other end of the hinge support 9 and is hinged together with the upper middle position of the front side of the slag gathering rod 11. At the same time, at the upper outer end of the turntable 2, a baffle 10 is fixedly connected to the side of the outer rear end of the movable hole 8 close to the hinge support 9, and a driving gear 302 is rotatably connected to the lower front end of the baffle 10. The front end of the driving gear 302 is fixedly connected to A linkage rod 401 is connected, and the other end of the linkage rod 401 is connected to the front side of the driving gear 302 and is rotatably connected to a slider 402. A sliding slot 403 distributed along the axial direction of the connecting rod 301 is opened in the middle position of the front side of the connecting rod 301, and the slider 402 is stuck in the sliding slot 403. Driven by the rotation of the driving gear 302, the linkage rod 401 drives the end of the connecting rod 301 connected to the slag gathering rod 11 to reciprocate up and down, and the rotation of the driving gear 302 is controlled by the servo motor 305 fixedly connected to the rear side of the baffle 10.

[0040] In order to allow the lower end of the slag gathering rod 11 to automatically swing to both sides and gather the slag at the mouth of the medium frequency furnace to the middle, a driven gear 303 meshing with the driving gear 302 is rotatably connected to the upper front end of the baffle 10, and a driving rod 304 is hinged on the front edge of the driven gear 303. The driving rod 304 is connected to the other end of the driven gear 303 and is hinged together with the upper rear end of the slag gathering rod 11. The driving rod 304 is driven to rotate by the rotation of the driven gear 303. Since the length of the driving rod 304 is fixed, the driving rod 304 pushes and pulls the upper end of the slag gathering rod 11 to swing to both sides under the rotation of the driven gear 303. At the same time, the slag gathering rod 11 and one end of the connecting rod 301 are hinged together. The lower end of the slag gathering rod 11 can swing to both sides to gather the slag at the mouth of the medium frequency furnace. The driving gear 302 and the driven gear 303 on the upper side are meshed together, so that the transmission can be performed synchronously. While the slag gathering rod 11 moves up and down, the bottom end can also swing to both sides at the same time. Since the rotation directions of the two gears are opposite, the position of the connection between the driving rod 304 and the driven gear 303 is adjusted so that when the slag gathering rod 11 moves, the lower end of the slag gathering rod 11 swings toward the middle, and when the slag gathering rod 11 moves upward, the slag gathering rod 11 swings outward to gather the slag. In addition, the rotation of the turntable 2 on the mounting plate 1 can gather the slag around the mouth of the medium frequency furnace, making it convenient for workers to scoop out the slag floating on the molten iron.

[0041] Embodiment 2:

[0042] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0043] In order to enable the turntable 2 to rotate automatically and stop rotating automatically after the driving force is removed, a worm gear 501 is fixedly connected to the upper side of the outer part of the turntable 2. A circular hole is opened in the middle of the worm gear 501, and the parts installed on the upper side of the turntable 2 are mounted inside. This circular hole is called a connecting hole 15. The worm gear 501 is fixedly connected to the upper side of the turntable 2, and a partition 502 is fixedly connected to both sides of the rear end of the upper side of the outer part of the mounting plate 1. A worm 503 is rotatably connected between the partitions 502. The worm 503 is meshed with the outer part of the worm gear 501, and the worm gear 501 is driven to rotate by the rotation of the worm gear 503. The unidirectional transmission characteristic that the worm gear can drive the worm wheel to rotate, while the worm wheel cannot drive the worm gear to rotate conversely, is utilized to realize the self-locking positioning rotation of the turntable 2, and the worm gear 503 is controlled to rotate by a second servo motor 12 installed on the outer side of the partition 502, so as to prevent workers from stirring the slag at the furnace mouth of the medium frequency furnace for a long time and being exposed to high temperature radiation for a long time.

[0044] Add slag remover to the molten iron heated in the medium frequency furnace, and place the support rod 7 connected to the lower end of the mounting plate 1 around the furnace mouth of the medium frequency furnace. After the slag remover absorbs the slag and waste in the molten iron and forms lumps floating on the molten iron, start the two motors, and the turntable 2 starts to rotate. When the lower end of the slag gathering rod 11 moves downward, the slag gathered at the edge of the furnace mouth is pushed to the middle. After the waste slag is continuously gathered, the workers scoop out the gathered waste slag. After the lower end of the slag gathering rod 11 is away from the furnace mouth, stop the two motors and carry out the next round of slag removal.

[0045] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
