Description

Technical Field

[0001] The invention belongs to the technical field of magnesium metal smelting equipment, and in particular relates to an automatic slag remover for magnesium metal production which can be remotely operated. Background Art

[0002] At present, the main method of smelting magnesium is thermal reduction, that is, using ferrosilicon to thermally reduce the magnesium oxide produced by calcining carbonate ore. Each smelting furnace has about 40 kiln tubes with a diameter of about 0.3 meters and a length of nearly 4 meters. The raw materials are magnesium ore powder and lime processed into magnesium nuclei in a certain proportion. Its size is similar to that of walnuts and its hardness is relatively low. During smelting, the smelting temperature is about 1200℃ and the duration is 8 to 10 hours. After the firing is completed, there will be about 70% slag in the kiln tube. The furnace will be stopped for about 5 to 8 minutes. When the furnace temperature drops to about 800℃ to 900℃, the slag will be removed. After emptying, the material will be loaded and the next smelting work will be carried out.

[0003] The traditional methods of slag removal from magnesium smelting furnaces mainly include manual slag removal, manually operated forklift with a long shovel and spiral auger slag removal.

[0004] However, there are the following problems with manual slag removal:

[0005] 1) Low production efficiency;

[0006] 2) The workload of slag removal is large, the reciprocating intensity is high, and the workers consume a lot of physical energy;

[0007] 3) Working near the furnace, high temperature causes serious occupational hazards and affects the health of workers;

[0008] 4) In summer, production often has to be stopped due to unbearable high temperatures;

[0009] 5) Due to the poor working environment, it is difficult for enterprises to recruit and retain workers, and labor costs are high;

[0010] The following problems exist when using a manually operated forklift with a long shovel to remove slag:

[0011] 1) This method is difficult to master and can easily collide with the smelting furnace, thereby damaging the smelting furnace;

[0012] 2) Constant reciprocating motion all day long and constant concentration, observing the high-temperature and high-light furnace mouth with human eyes, will also cause occupational hazards to workers and affect their health;

[0013] The spiral auger slag removal method has problems such as backward technology, low degree of automation, poor durability, large space occupied on the working surface, inflexible operation, and difficulty in transfer.

[0039] 2. The present invention provides an automated slag remover for magnesium production that can be remotely operated. By adopting a Mecanum wheel assembly as a moving wheel, there is no need to lay a dedicated track. The machine can move in a plane in all directions and turn around on the spot, so that the slag remover can be used for working surfaces of different widths and sizes. During maintenance and overhaul, the machine can also leave the working environment and operate in a safe area, thereby ensuring the smoothness of the working surface and avoiding the danger of a cross-working environment.

[0040] 3. The present invention provides an automated slag remover for magnesium metal production that can be remotely controlled. By designing the bearing support of the vehicle body as a U-shaped sinking heavy-duty steel structure frame, the slag remover can save height dimensions and can be adapted to the heights of production furnaces of different enterprises.

[0041] 4. The present invention provides an automatic slag remover for magnesium metal production that can be remotely controlled. By adopting an extended-range power system, there is no need to pull a dedicated power supply line, so it is more flexible to use and has a longer battery life. It can also carry more power-consuming mechanisms to provide sufficient power supply guarantee, thereby making the slag remover more automated.

[0042] 5. The present invention provides an automated slag remover for magnesium production that can be remotely controlled. A slag remover handle support mechanism is provided, and the handle support screw module of the slag remover handle support mechanism can drive the guide wheel shaft to rise and fall with the handle, and adaptively and synchronously follow the rise and fall, thereby greatly improving the stability and flexibility of the mechanism, improving the durability of key components, and achieving reasonable force on the equipment.

[0043] 6. The present invention provides an automatic slag remover for magnesium metal production that can be remotely operated. By setting a compression / tensile force sensor at the junction of the rotating shaft and the shovel handle, the force condition can be detected at all times when the mechanism is automatically running or manually operated, thereby avoiding overload and ensuring the safety of the furnace and equipment.

[0044] 7. The present invention provides an automatic slag remover for magnesium metal production that can be remotely controlled. By setting a distance measuring sensor, the relative position of the slag remover and the furnace mouth can be automatically adjusted to avoid actuator action errors caused by position deviations during work, thereby ensuring smooth and correct slag removal.

[0045] 8. The present invention provides an automatic slag remover for magnesium metal production that can be remotely controlled.

[0080] For specific implementation, see Figure 5 As shown, the concentric slag shovel 12 is foldably connected to the shovel handle 11 via a hinge pin 15 and a locking ring 16 .

[0081] Working principle:

[0082] The slag remover is manually controlled by a remote controller to move horizontally to the front of the furnace, so that the shovel handle 11 is roughly aligned with the furnace center, and the concentric slag remover 12 is close to the furnace mouth, and the calibration work is prepared; the slag remover is manually controlled to perform left and right fine adjustments through the Mecanum wheel assembly 13 and the slag remover lifting mechanism 9 up and down fine adjustments, so that the relative position of the slag remover 12 and the end face of the furnace mouth is corrected to a workable state; then the front and rear calibration commands are started by the remote controller, and the body of the slag remover detects the distance between the body of the slag remover and the end face of the furnace mouth through the distance measuring sensor 610 carried, and automatically performs forward and backward micro-movements, so that the body and the furnace mouth are kept in a preset relative position that can carry out automatic operation; after the calibration position, the automatic slag removal command is manually started by remote control, and the slag removal machine will perform slag removal work according to the preset action.

[0083] Slag shoveling action: the slide plate 74 of the slag shovel longitudinal movement mechanism 7 drives the slag shovel lifting mechanism 9 to move forward to the preset position to shovel slag. The forward and backward movements of the slide plate 74 are completed by the first reducer 76 driving the first reducer 76 to drive the gear to move on the rack 78.

[0084] Slag dumping action: After the slag shovel is completed, the slide plate 74 and the driven slag shovel lifting mechanism 9 return to the original position, and then the concentric slag shovel 12 is turned 90 degrees under the action of the slag shovel rotating mechanism 6 to dump the slag. The slag dumping action is driven by the second drive motor 62 to drive the second reducer 61, which drives the rotating shaft 64 through the coupling 63, and the rotating shaft 64 drives the shovel handle 11, and the shovel handle 11 drives the concentric slag shovel 12 to flip and complete the slag dumping. The concentric slag shovel 12 and the shovel handle 11 are connected by a hinge pin 15. When folding is not required for transfer, they are kept coaxial and locked by a locking ring 16 to keep them coaxial.

[0085] Automatic slag removal: According to the actions of the preset program, the stepping position of each slag shoveling will be different; after shoveling the slag, pour it back out of the furnace, and then turn the slag over; after pouring the slag, the slag shovel will turn back to the horizontal position; then shovel the slag into the furnace according to the preset, and the preset slag removal program is executed.

[0086] Support action: Since the shovel handle 11 is relatively long, it is a long cantilever in the mechanism, which will affect the stability of the mechanism operation and the fatigue destructiveness of the components. Therefore, a slag shovel handle support mechanism 8 is set near the shovel head side; the shovel handle support mechanism 8 holds up the shovel handle 11 by the guide wheel 85, so that the shovel handle 11 can slide forward and backward on the guide wheel 85 without obstruction. The guide wheel 85 is installed on the guide wheel shaft 84, and the guide wheel shaft 84 is fixed on the slide plate 87 of the shovel handle support screw module 82 by two fixing frames 88. As a support point, the guide wheel 85 moves synchronously and at the same speed according to the rise and fall of the slag shovel lifting mechanism 9 according to the preset program, ensuring that the support point and the fixed point of the shovel handle 11 are always kept horizontal.

[0087] Folding action: When the slag shovel is transferred to the working surface or finished work, in order not to occupy space and reduce danger, the slag shovel should be folded and put away. A special small crowbar is inserted into the unlocking hole of the lock ring 16 to rotate the lock ring 16 to disengage the concentric slag shovel 12 from the locked state of the joint. Then the hook at the end of the wire rope of the winch 24 is hung on the hook hole next to the hinge of the winch 24, and then the remote control is operated to start the winch 24. The winch 24 begins to slowly retract the wire rope until the slag shovel is upright and put away. Otherwise, it is unfolded.

[0088] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
