Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnesium alloy smelting, specifically to an adjustable slag skimmer. Background Technology
[0002] During the recycling and remelting of magnesium alloys, magnesium, being an active metal, readily reacts with oxygen and nitrogen at high temperatures to generate magnesium oxide and magnesium nitride impurities. These impurities form scum on the surface of the molten magnesium, severely affecting the quality and performance of the magnesium alloy.
[0003] In actual production, workers need to use slag-removing tools to skim off the floating slag. Currently, the slag-removing spoon handle and slag-removing tray used in magnesium alloy smelting are integrated. This integrated slag-removing spoon has two main drawbacks: firstly, its length is not adjustable; a spoon that is too long has a large operating radius, making it inconvenient to use; and a spoon that is too short requires workers to walk around the edge of the furnace to remove floating slag from distant magnesium molten metal, posing high-temperature and safety risks, and resulting in low work efficiency. Secondly, the slag-removing tray is prone to deformation due to prolonged contact with high-temperature molten magnesium. When the slag-removing tray is damaged, a new slag-removing spoon must be replaced, increasing operating costs.
[0004] For example, Chinese patent CN221516083U discloses a slag-removing spoon structure for continuous casting molten copper. It includes a slag-removing spoon body, which is a structure made of graphite template. A recessed slag-removing cavity is provided at the upper part of the slag-removing spoon body, and multiple perforations penetrating the slag-removing spoon body are provided inside the cavity. An extension is provided on one side of the slag-removing spoon body, and the extension is connected to a handle.
[0005] The handle length and operating radius of this continuous casting molten copper slag skimmer are fixed, and the aforementioned problems still exist. Utility Model Content
[0006] The purpose of this invention is to provide an adjustable slag scoop. The overall length of the adjustable slag scoop can be adjusted, and the operating radius can be adjusted for different sizes of furnace openings. The angle between the slanted rod and the filter plate makes slag scooping more convenient.
[0007] To achieve the above objectives, this utility model provides an adjustable slag ladle, comprising a handle, a first connecting rod, a second connecting rod, an inclined rod, and a filter plate connected in sequence. The end of the first connecting rod is configured to be inserted into the front end of the handle. The side of the first connecting rod is provided with multiple locking holes. The side of the handle is equipped with a press-locking member that can be locked into the locking holes. The second connecting rod is detachably connected to the inclined rod. The inclined rod and the filter plate form an angle α.
[0008] Preferably, the push-button lock includes a base fixed to the side of the handle, the base having a through hole communicating with the lock hole, and a lock cylinder coaxial with the through hole fixed to the base; the lock cylinder has a vertical hole on its side, a side lock groove on one side of the bottom of the vertical hole, a lock pin that mates with the lock hole is disposed through the lock cylinder, a knob is connected to the upper end of the lock pin, a spring is sleeved on the lock between the lock cylinder and the knob, and a lock plate that can rotate into the side lock groove is fixed to the side of the lock pin.
[0009] Preferably, the bottom surface of the knob is provided with a recess, and the upper end of the spring is disposed in the recess.
[0010] Preferably, the filter plate is provided with a plurality of filter holes.
[0011] Preferably, the diameter of the filter pores gradually increases from top to bottom.
[0012] Preferably, the outer end of the inclined rod is fixedly connected to a sleeve, and the front end of the second connecting rod is inserted into the sleeve and fixed by at least two fixing pins on the side.
[0013] Preferably, a reinforcing rib is provided on each side of the inclined rod; the two ends of the reinforcing rib are respectively fixed to the sleeve and the filter plate.
[0014] Preferably, the included angle α is in the range of 20-40°.
[0015] Preferably, the handle cover is provided with a heat insulation sleeve.
[0016] According to the above technical solution, this utility model provides an adjustable slag ladle, including a handle, a first connecting rod, a second connecting rod, an inclined rod, and a filter plate connected in sequence. The end of the first connecting rod is configured to be inserted into the front end of the handle. The side of the first connecting rod is provided with multiple locking holes. The side of the handle is equipped with a press lock that can be locked into the locking holes. The second connecting rod is detachably connected to the inclined rod. The inclined rod and the filter plate form an angle α.
[0017] The adjustable slag ladle has the following advantages: 1. By adjusting the depth of the first connecting rod inserted into the handle, the pressing lock can be locked in different lock holes to adjust the overall length of the adjustable slag ladle, thereby adjusting the operating radius; 2. By making the connection between the second connecting rod and the inclined rod detachable, if the filter plate deforms due to prolonged contact with the high temperature of molten magnesium, the filter plate structure can be directly removed and replaced with a new one, without having to replace the entire slag ladle, greatly saving on usage costs; 3. By setting an angle between the inclined rod and the filter plate, it is more labor-saving and convenient for workers to use the slag ladle.

Detailed Implementation
[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0028] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.
[0029] See Figure 1-5The adjustable slag ladle shown includes a handle 1, a first connecting rod 2, a second connecting rod 3, an inclined rod 13, and a filter plate 4 connected in sequence. The end of the first connecting rod 2 is configured to be inserted into the front end of the handle 1. The side of the first connecting rod 2 is provided with multiple locking holes 8. The side of the handle 1 is equipped with a press lock 10 that can be locked into the locking holes 8. The second connecting rod 3 is detachably connected to the inclined rod 13, and the inclined rod 13 forms an angle α with the filter plate 4.
[0030] By implementing the above technical solution, by adjusting the depth of the insertion of the first connecting rod 2 into the handle 1, the pressing lock 10 can be locked in different lock holes 8 to adjust the overall length of the adjustable slag ladle, thereby adjusting the operating radius. This satisfies the requirements for both near and far slag in the molten magnesium furnace, allowing workers to retrieve distant slag without having to walk along the edge of the furnace, reducing high temperature and safety risks. By making the connection between the second connecting rod 3 and the inclined rod 13 detachable, if the filter plate 4 deforms due to prolonged contact with the high temperature of the molten magnesium, the filter plate 4 can be directly removed and replaced with a new one, without replacing the entire slag ladle, greatly saving on usage costs. By setting an angle between the inclined rod 13 and the filter plate 4, it is more labor-saving and convenient for workers to use the slag ladle. In addition, the diameter of the second connecting rod 3 can be set smaller than the diameter of the first connecting rod 2 to reduce the overall weight.
[0031] In this embodiment, to further provide a push-button lock 10, the push-button lock 10 includes a base 9 fixedly connected to the side of the handle 1. The base 9 is provided with a through hole that can communicate with the lock hole 8. A lock cylinder 14 coaxial with the through hole is fixedly connected to the base 9. A vertical hole 15 is provided on the side of the lock cylinder 14. A side lock groove 17 is provided on one side of the bottom of the vertical hole 15. A lock pin 19 that cooperates with the lock hole 8 is provided through the lock cylinder 14. A knob 18 is connected to the upper end of the lock pin 19. A spring 21 is sleeved between the lock cylinder 14 and the knob 18. A lock plate 16 that can rotate into the side lock groove 17 is fixedly connected to the side of the lock pin 19.
[0032] In use, press knob 18 to insert the locking pin 19 into the corresponding lock hole 8, and then rotate the locking pin 19 by knob 18 to make the locking plate 16 engage in the side lock groove 17. At this time, the spring 21 is in a compressed state, which can provide upward pressure to knob 18, so that the upper surface of the locking plate 16 presses against the upper surface of the side lock groove 17, improving stability. When the length needs to be adjusted, rotate knob 18 in the opposite direction to make the locking plate 16 rotate to the position of the vertical hole 15. Under the reset action of spring 21, the knob 18 and the locking plate 16 move upward. Then adjust the insertion depth of the first connecting rod 2 in the handle 1, and repeat the above steps to lock it into the new lock hole 8.
[0033] In this embodiment, the bottom surface of the knob 18 is provided with a recess 20, and the upper end of the spring 21 is disposed within the recess 20. This arrangement allows for the use of a longer spring 21, increasing the travel of the elastic deformation and better realizing the elastic pressing and reset operation.
[0034] In this embodiment, the filter plate 4 is provided with a plurality of filter holes 5. The shape of the filter holes 5 can be selected as needed, such as circular, elliptical, or triangular. The filter plate 4 can be flat, curved like a strainer, or square.
[0035] In this embodiment, to further provide a structure for the filter hole 5, the diameter of the filter hole 5 gradually increases from top to bottom. During slag removal, the magnesium slag adheres to the upper surface of the filter plate 4 and can be easily removed by gentle tapping. When the magnesium slag adheres to the lower surface of the filter plate 4, it is also easy to remove by gentle tapping due to the gradually increasing diameter of the filter hole 5. Simultaneously, the filter hole 5 adopts a conical structure that is smaller at the top and larger at the bottom, which also facilitates the leakage of molten magnesium during slag removal and prevents clogging of the filter hole 5.
[0036] In this embodiment, a sleeve 12 is fixedly connected to the outer end of the inclined rod 13, and the front end of the second connecting rod 3 is inserted into the sleeve 12 and fixed by at least two fixing pins 7 on the side. In this way, when the filter plate 4 needs to be replaced due to deformation from long-term use, it is only necessary to remove the fixing pins 7 and pull the sleeve 12 out from the front end of the second connecting rod 3. Of course, the fixing pins 7 can also be replaced by screws, which are screwed through the side of the sleeve 12 and onto the front side of the second connecting rod 3.
[0037] In this embodiment, a reinforcing rib 6 is provided on each side of the diagonal rod 13; the two ends of the reinforcing rib 6 are respectively fixed to the sleeve 12 and the filter plate 4. Since the slag removal tray structure is prone to deformation due to long-term contact with high-temperature molten magnesium, the setting of the reinforcing ribs 6 on both sides increases the connection strength between the filter plate 4 and the second connecting rod 3, which can effectively extend the service life of the slag removal tray and further reduce the cost of use.
[0038] In this embodiment, the included angle α ranges from 20 to 40°. In one embodiment, α can be set to 30°.
[0039] In this embodiment, the handle 1 is covered with a heat-insulating sleeve 11. By covering the handle 1 with the heat-insulating sleeve 11, workers are prevented from being burned by contact with high temperatures during operation.
[0040] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0041] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0042] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
