Description

Technical Field

[0001] This invention belongs to the technical field of magnesium smelting equipment, and particularly relates to an automated slag removal machine for magnesium production that can be remotely operated. Background Technology

[0002] Currently, the main method for smelting magnesium is the thermal reduction method, which involves using ferrosilicon to thermally reduce magnesium oxide produced from calcined carbonate ore. Each smelting furnace has approximately 40 kiln tubes, each about 0.3 meters in diameter and nearly 4 meters long. The raw material is magnesium ore powder and lime processed into magnesium nuclei in a certain proportion. These nuclei are similar in size to walnuts and have low hardness. During smelting, the temperature is approximately 1200℃, and the smelting time is 8–10 hours. After calcination, about 70% of the material remains in the kiln tubes. The furnace is shut down for about 5–8 minutes, and when the furnace temperature drops to about 800℃–900℃, the slag is removed. After the furnace is emptied, the material is loaded for the next smelting cycle.

[0003] Traditional methods for removing slag from magnesium smelting furnaces mainly include manual slag removal, manual operation of a forklift with a long shovel for slag removal, and spiral auger slag removal.

[0004] However, the manual slag removal method has the following problems:

[0005] 1) Low production efficiency;

[0006] 2) The slag removal work is extensive, involves high repetition intensity, and consumes a great deal of the workers' physical strength;

[0007] 3) Working near the furnace exposes workers to high temperatures, posing significant occupational hazards and impacting their health.

[0008] 4) Production often has to be suspended in the summer due to unbearable high temperatures;

[0009] 5) Due to poor working conditions, companies face difficulties in recruiting and retaining employees, resulting in high labor costs;

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

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

[0012] 2) The constant repetitive movements and the need to concentrate at all times, especially when observing the high temperature and high light of the furnace opening, can cause occupational hazards to workers and affect their health.

[0013] The use of spiral hinge slag removal has problems such as outdated technology, low degree of automation, poor durability, large space occupation on the working face, inflexible operation, and difficulty in relocation.

[0014] Therefore, there is an urgent need to design a slag removal machine for magnesium production to solve the problems faced by the existing technology. Summary of the Invention

[0039] 2. The present invention provides an automated slag removal machine for magnesium production that can be remotely controlled. By using Mecanum wheel components as moving wheels, it eliminates the need to lay dedicated tracks and can move in all directions on a plane and turn around on the spot. This makes the slag removal machine suitable for working surfaces of different widths and sizes.

[0041] 4. The present invention provides an automated slag removal machine for magnesium production that can be remotely controlled. By adopting a range-extended power system, it eliminates the need for a dedicated power supply line, making it more agile and providing a longer operating time. It can also accommodate more power-consuming components to ensure sufficient power supply, thereby increasing the degree of automation of the slag removal machine.

[0042] 5. The present invention provides an automated slag removal machine for magnesium production that can be remotely controlled. By setting a slag removal shovel handle support mechanism, and the shovel handle support screw module of the shovel handle support mechanism can drive the guide wheel shaft to rise and fall with the shovel handle, adaptively and synchronously following the rise and fall, which greatly improves the stability and flexibility of the mechanism, improves the durability of key components, and achieves reasonable stress on the equipment.

[0045] 8. The present invention provides an automated slag removal machine for magnesium metal production that can be remotely operated. By adding an air-cooled air conditioning system, the shovel handle can be cooled efficiently, and key nodes can be cooled with cold air. This can effectively block the transmission of high temperature and ensure the normal movement of the mechanism joints.

This allows for continuous detection of the force and the relative position of the slag remover and the furnace opening, thus preventing overload and ensuring the safety of the furnace and equipment. It also prevents errors in the actuator's operation due to positional deviations, ensuring smooth and correct slag removal.

[0080] For specific implementation, please refer to 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 manual operator remotely controls the slag removal machine to move horizontally to the front of the furnace, aligning the shovel handle 11 roughly with the furnace center and the concentric slag removal shovel 12 close to the furnace opening, ready for calibration. The manual operator then uses the Mecanum wheel assembly 13 to make left and right fine adjustments and the slag removal shovel lifting mechanism 9 to make up and down fine adjustments, calibrating the relative position of the slag removal shovel 12 and the furnace opening end face to a working state. The operator then initiates the front and rear calibration commands via the remote control. The vehicle body detects the distance between the slag removal machine body and the furnace opening end face through the onboard distance sensor 610, and automatically performs forward and backward fine movements to keep the vehicle body and the furnace opening at a preset relative position where automatic operation can be carried out. After the calibration position is reached, the manual operator initiates the automatic slag removal command via the remote control, and the slag removal machine will perform slag removal work according to the preset actions.

[0083] Slag removal action: The sliding plate 74 of the slag removal shovel longitudinal movement mechanism 7 drives the slag removal shovel lifting mechanism 9 to move forward to the preset position to remove slag. The forward and backward movement of the sliding plate 74 is driven by the first reducer 76, which in turn drives the gear to move on the rack 78.

[0084] Slag Disposal Action: After slag removal is completed, the sliding plate 74 and the driven slag shovel lifting mechanism 9 return to their original positions. Then, the concentric slag shovel 12 rotates 90 degrees under the action of the slag shovel rotation mechanism 6 to dispose of the slag. The slag disposal action is driven by the second drive motor 62, which drives the second reducer 61, which in turn drives the rotating shaft 64 through the coupling 63. The rotating shaft 64 then drives the shovel handle 11, which in turn drives the concentric slag shovel 12 to rotate, completing the slag disposal. The concentric slag shovel 12 and the shovel handle 11 are connected by a hinge pin 15. When not folded for relocation, they remain coaxial and are locked by a locking ring 16 to maintain their coaxiality.

[0085] Automatic slag removal: The slag removal step position will be different each time according to the preset program; after slag removal, it is poured back outside the furnace and then flipped and poured out again; after pouring out the slag, the slag removal shovel rotates back to horizontal; and then slag is removed again according to the preset furnace entry, and so on to complete the preset slag removal program.

[0086] Support mechanism: Due to the relatively long length of the shovel handle 11, which constitutes a long cantilever in the mechanism, it affects the stability of the mechanism's operation and the fatigue damage to its components. Therefore, a shovel handle support mechanism 8 is installed near the shovel head. The shovel handle support mechanism 8 is supported by guide wheels 85, allowing the shovel handle 11 to slide forward and backward without obstruction on the guide wheels 85. The guide wheels 85 are mounted on guide wheel shafts 84, which are fixed to the sliding blocks 87 of the shovel handle support screw module 82 by two fixing brackets 88. The guide wheels 85 serve as a support point and move synchronously and at the same speed according to the rising and falling of the shovel lifting mechanism 9 according to a preset program, ensuring that the support point of the shovel handle 11 remains horizontally aligned with the fixed point at all times.

[0087] Folding Action: When the slag removal machine is moving to a different work site or finishing work, the slag removal shovel must be folded up to save space and reduce danger. A person uses a special small pry bar to insert into the unlocking hole of the locking ring 16 and rotates the locking ring 16 to disengage the concentric slag removal shovel 12 from its locked position. The person then hooks the hook at the end of the wire rope of the winch 24 onto the hook hole next to the hinge of the winch 24. The winch 24 is then started by operating the remote control, and it slowly retracts the wire rope until the slag removal shovel is upright and retracted. Conversely, unfolding the slag removal shovel unfolds it.

[0088] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
