Technical Field

[0001] The invention relates to the technical field of furnace openings, and in particular to a furnace opening for a reverberatory furnace which is easy to repair and a repair method. Background Art

[0002] Smelting is a refining technology that refers to the use of roasting, smelting, electrolysis, and chemical agents to extract metals from ores, reduce impurities in the metal or increase certain components in the metal to refine the required metal.

[0003] In the aluminum alloy smelting industry, the reverberatory furnace is the main equipment for melting aluminum. During the use of the aluminum alloy reverberatory furnace, the scum on the molten aluminum needs to be cleaned. Frequent cleaning will cause certain damage to the furnace mouth. The upper part of the furnace mouth has less daily wear and tear and wears slowly. As for the position of the furnace threshold at the bottom of the furnace mouth, which is more easily damaged, the general design is to integrate the entire furnace mouth design as a whole, which is more troublesome and time-consuming to repair later. Its disadvantages are: 1. The maintenance is complicated. The design maintenance requires the removal of a lot of furnace mouths and re-casting, and the whole process is time-consuming; 2. Waste of raw materials. The furnace threshold at the bottom of the furnace door is worn out. When repairing the threshold, in order to ensure the quality of the repair, other parts will be removed, resulting in a certain amount of raw material waste; 3. Waste of time. The integrated furnace door design requires the aluminum reverberatory furnace to be shut down and the furnace temperature to be lowered to room temperature during maintenance. Then the workers remove the old furnace mouth, re-pour, and then bake it for use. The whole process is time-consuming and will affect normal production. 4. Waste of cost, because the maintenance process is rather complicated, and the whole process involves stopping the furnace and then heating it up, which will waste gas, etc. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 6 The present invention provides a furnace mouth for a reverberatory furnace that is easy to repair, including two fixed frames 2 and a vertical plate 3 connected between the two fixed frames 2. A plurality of unit blocks 6 are connected to the fixed frames 2, and the plurality of unit blocks 6 form a furnace threshold. The traditional furnace threshold is an integrated design. When the furnace threshold is damaged, the furnace needs to be stopped to repair and install the furnace threshold. The fixed frame 2 is connected with a clamping mechanism for clamping the unit block 6. The clamping mechanism includes a screw 13, a push block 14, and a conical tooth 15. The conical tooth 15 is used to drive the screw 13 to rotate. The screw 13 is used to drive the push block 14 to reciprocate. The push block 14 matches the L-shaped plate 10 connected to the bottom of the unit block 6. The L-shaped plate 10 is used to limit the unit block 6. The conical tooth 15 is connected with a driving mechanism for driving the conical tooth 15 to rotate.

[0020] After multiple unit blocks 6 are installed, the driving mechanism is used to drive the screw 13 to rotate, so that the push block 14 moves forward. The push block 14 applies a thrust to the L-shaped plate 10 at the bottom of the rightmost unit block 6, which can drive multiple unit blocks 6 to move synchronously to the left, so that multiple unit blocks 6 are pressed against each other. Combined with the use of the L-shaped plate 10, the overall structure is more compact and stable, and easy to use. Finally, the filling block 4 is installed to avoid gaps.

[0021] When a unit block 6 needs to be repaired or replaced, first take out the filling block 4, and use the driving mechanism to drive the screw 13 to rotate, so that the push block 14 moves back, that is, the push block 14 is separated from the L-shaped plate 10, so as to realize the synchronous loosening of multiple unit blocks 6, and apply a rightward thrust to the damaged unit block 6, so as to facilitate the disassembly and replacement of the damaged unit block 6, and then install a new unit block 6, and repeat the above-mentioned unit block 6 positioning and locking steps.

[0022] The pressing mechanism further includes a slide groove 16 , and the push block 14 is slidably connected to the slide groove 16 , so as to improve the stability of the reciprocating movement of the push block 14 and accurately press the corresponding L-shaped plate 10 .

[0023] The screw rod 13 and the conical tooth 15 are located in the slide groove 16 , and both ends of the screw rod 13 are rotatably connected to the fixed frame 2 , thereby improving the rotation stability of the screw rod 13 .

[0024] The fixing frame 2 is provided with an inner cavity 11 and a plurality of limiting holes 12. The limiting holes 12 are connected to the inner cavity 11. The limiting holes 12 are rectangular holes, and the length of the limiting holes 12 is greater than the length of the L-shaped plate 10. When installing the unit block 6, align the L-shaped plate 10 with the limiting holes 12, insert the L-shaped plate 10 into the limiting holes 12, and position the bottom of the L-shaped plate 10 in the inner cavity 11. Then, a leftward thrust is applied to the unit block 6, so that the L-shaped plate 10 hooks the fixing frame 2, and then cooperates with the placement groove 17 to achieve preliminary limiting of the unit block 6.

[0025] The driving mechanism includes a rotary handle 5, a conical tooth 2 18, a rotating shaft 19, a guide groove 20, a connecting column 21, a spring 22, a limiting groove 23, and a rotating groove 24. The end of the rotating shaft 19 is connected to the conical tooth 2 18, and the conical tooth 2 18 matches the conical tooth 1 15. The guide groove 20 is arranged in the rotating shaft 19, and the guide groove 20 matches the connecting column 21. The end of the connecting column 21 is connected to the rotary handle 5, and the rotary handle 5 matches the limiting groove 23. The limiting groove 23 is arranged on the side of the fixed frame 2. The rotating groove 24 is used to guide the rotating shaft 19. The spring 22 is used to drive the rotary handle 5 to move in a direction close to the rotating shaft 19. Apply a pulling force to the rotary handle 5 to separate the rotary handle 5 from the limiting groove 23. At this time, the connecting column 21 slides in the guide groove 20, and the spring 22 is in an elongated state. Then the rotary handle 5 is driven to rotate, which synchronously drives the connecting column 21, the rotating shaft 19, and the second conical tooth 18 to rotate. The second conical tooth 18 cooperates with the first conical tooth 15 to realize the rotation of the screw 13, which is convenient for moving the push block 14. When the push block 14 is in a suitable position, the rotary handle 5 is directly released, and the elongated spring 22 drives the rotary handle 5 to return to its original position, so that the rotary handle 5 is connected with the limiting groove 23, and the rotary handle 5 is automatically locked, thereby avoiding the hidden danger of rotation of the screw 13, and the operation is simple and convenient.

[0026] The cross-section of the rotary handle 5 and the guide groove 20 is a regular polygonal structure, and the connecting column 21 is slidably connected to the guide groove 20 .

[0027] The spring 22 is located in the rotating groove 24 , and both ends of the spring 22 are connected to the rotating handle 5 and the rotating shaft 19 .

[0028] The fixing frame 2 is provided with a placement groove 17 matching with the unit block 6. The end of the placement groove 17 is detachably connected with the filling block 4. By placing the unit block 6 in the placement groove 17, the front and rear position of the unit block 6 can be limited, and the unit block 6 can be moved along the length direction of the placement groove 17.

[0029] A pull groove 7 is provided on the top of the unit block 6, and the pull groove 7 can be pulled to conveniently lift the unit block 6 for replacement and installation.

[0030] When replacing and repairing the unit block 6 located at the top, the unit block 6 can be supported by a supporting tool to prevent it from falling when the unit block 6 is loosened.

[0031] A maintenance method for a furnace mouth of a reverberatory furnace that is easy to maintain comprises the following steps: Step 1: Pull the rotary handle 5 and drive the rotary handle 5 to rotate, synchronously drive the connecting column 21, the rotating shaft 19, and the conical tooth 2 18 to rotate, the conical tooth 2 18 cooperates with the conical tooth 1 15 to realize the rotation of the screw 13, and then drive the push block 14 to move back and forth. At this time, the spring 22 is in an elongated state. When the push block 14 moves forward, the push block 14 applies a thrust to the L-shaped plate 10, which can push the rightmost unit block 6 forward, thereby making the multiple unit blocks 6 move to the left as a whole, and squeeze each other to improve the stability of the overall connection, and then the filling block 4 is installed to realize the rapid assembly of the unit block 6, loosen the rotary handle 5, and the elongated spring 22 drives the rotary handle 5 to return, so that the rotary handle 5 is docked with the limit groove 23, which can prevent the rotating shaft 19 from rotating, improve the stability of the push block 14, and ensure that the multiple unit blocks 6 are connected and not easy to loosen; Step 2: When a unit block 6 is damaged and needs to be replaced and repaired, remove the filling block 4, rotate the handle 5 to move the push block 14 backward, so as to simultaneously loosen multiple unit blocks 6, then disassemble and replace the damaged unit block 6, install a new unit block 6, and finally repeat the unit block 6 installation steps of step 1.
