Description

Technical Field

[0001] The utility model relates to the technical field of annealing devices, in particular to an annealing device for producing refractory materials with crack prevention. Background Art

[0002] In the production of refractory materials, fused cast bricks have a wide range of applications in high-temperature industries due to their excellent high-temperature resistance and good chemical stability. However, in the production process of fused cast bricks, the annealing link is crucial and directly affects the quality and performance of fused cast bricks.

[0003] In terms of the demoulding operation of the existing fused cast brick annealing devices, relatively traditional methods are usually adopted. For example, some devices perform demoulding treatment on each mold box separately, requiring manual operation one by one, or using a simple mechanical structure that can only process a small number of mold boxes at a time.

[0004] The existing fused cast brick annealing devices in the prior art cannot achieve efficient and convenient demoulding operations for the fused cast bricks in multiple mold boxes simultaneously during the demoulding operation. This not only makes the operation process cumbersome, consuming a large amount of time and manpower, but also has low efficiency and is difficult to meet the requirements of modern large-scale production. Therefore, an annealing device for producing refractory materials with crack prevention is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides an annealing device for producing refractory materials with crack prevention, aiming to improve the problem that the existing fused cast brick annealing devices cannot achieve efficient and convenient demoulding operations for the fused cast bricks in multiple mold boxes simultaneously during the demoulding operation.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: An annealing device for producing refractory materials with crack prevention, including a carriage and a top cover. A plurality of mold boxes are arranged inside the carriage. Two electric telescopic rods are fixedly connected to the outside of the carriage. The output end of the electric telescopic rod is fixedly connected to a rack. Two limiting rods are fixedly connected to the inner wall of the carriage. A plurality of limiting blocks are slidably connected to the outside of the limiting rods. One end of the limiting block is rotatably connected to a connecting rod. The other end of the connecting rod is fixedly connected to a gear. The top of the limiting block is rotatably connected to an adapter rod. The top of the adapter rod is rotatably connected to a push plate. An auxiliary component is arranged outside the carriage, and the auxiliary component is used to open or close the top cover.

[0007] As a further description of the above technical solution:

[0008] The auxiliary component includes a fixing frame, the outer side of the fixing frame is fixedly connected to the outer side of the carriage, a wire reel is rotatably connected to the inner side of the fixing frame, a pulling rope is sleeved on the outer side of the wire reel, a turntable is rotatably connected to the outer side of the fixing frame, a handle is fixedly connected to the outer side of the turntable, one end of the turntable is fixedly connected to one end of the wire reel, a pulley is fixedly connected to the outer side of the carriage, and a connecting block is fixedly connected to the top of the top cover.

[0009] As a further description of the above technical solution:

[0010] The outer side of the pulling rope is slidably connected to the outer side of the pulley, and one end of the pulling rope is fixedly connected to the outside of the connecting block.

[0011] As a further description of the above technical solution:

[0012] A slot is opened at the top of the fixing frame, and a jack is opened inside the handle.

[0013] As a further description of the above technical solution:

[0014] A plug rod is inserted and matched with the inner walls of the slot and the jack, and an anti-slip pattern is arranged on the outer side of the plug rod.

[0015] As a further description of the above technical solution:

[0016] The bottoms of the two racks are both slidably connected to the inner bottom wall of the carriage, and the multiple gears are respectively meshed with the corresponding racks.

[0020] A sealing groove is opened at the top of the carriage, a sealing plate is fixedly connected to the bottom of the top cover, and the sealing plate is matched with the sealing groove.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, by starting the electric telescopic rod and making its output end extend, the force is transmitted to the gear through the rack. Since the gear is meshed with the rack, the gear will rotate accordingly. The rotation of the gear drives the limiting block to slide on the limiting rod through the connecting rod. At the same time, the top of the limiting block is connected to the push plate through the connecting rod. Therefore, the push plate will slide on the inner wall of the mold box, and the sliding of the push plate pushes the fused brick in the mold box, realizing the simultaneous demolding of the fused bricks in multiple mold boxes, greatly improving the operation efficiency.

[0023] 2. In the present utility model, the rotating handle drives the turntable to rotate. The rotation of the turntable causes the wire-releasing cylinder to rotate, thereby winding the pulling rope. The pulling rope can reduce friction through the pulley. At the same time, the pulling rope pulls the connecting block to open the top cover. After opening, the handle is fixed by inserting the insertion rod into the slot and the jack, preventing the wire-releasing cylinder from rotating, so as to prevent the top cover from closing when the staff takes out the electrofused brick, which may cause harm to the staff. When the carriage is closed, the sealing plate on the top cover cooperates with the sealing groove on the carriage, forming a closed annealing environment, which helps to prevent the heat and gas generated during the annealing process from leaking into the external environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Referring to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the present utility model: an annealing device for the production of refractory materials resistant to cracking, including a carriage 1 and a top cover 2. A plurality of mold boxes 3 are arranged inside the carriage 1. Two electric telescopic rods 4 are fixedly connected to the outside of the carriage 1. The output ends of the electric telescopic rods 4 are fixedly connected with racks 5. The bottoms of the two racks 5 are both slidably connected to the inner bottom wall of the carriage 1. Two limiting rods 6 are fixedly connected to the inner wall of the carriage 1. A plurality of limiting blocks 7 are slidably connected to the outside of the limiting rods 6. One end of a connecting rod 11 is rotatably connected to the outside of the limiting block 7. The other end of the connecting rod 11 is fixedly connected with a gear 10. A plurality of gears 10 are respectively engaged with the corresponding racks 5. One end of a connecting rod 8 is rotatably connected to the top of the limiting block 7. The top of the connecting rod 8 is rotatably connected to a push plate 9. The outsides of the plurality of push plates 9 are respectively slidably connected to the inner walls of the corresponding mold boxes 3.

[0034] Specifically, after annealing is completed, it is necessary to take out the fused cast bricks. Start the electric telescopic rod 4 to make its output end extend. As the electric telescopic rod 4 extends, the rack 5 fixed to its output end also moves accordingly. Since the rack 5 is engaged with the gear 10, the gear 10 will rotate as the rack 5 moves. The rotation of the gear 10 drives the limiting block 7 to slide on the limiting rod 6 through the connecting rod 11. And the connecting rod 8 at the top of the limiting block 7 is connected to the push plate 9. Therefore, the push plate 9 will slide on the inner wall of the mold box 3 as the limiting block 7 moves. The sliding of the push plate 9 pushes the fused cast bricks in the mold box 3 to make them break out of the mold, so as to realize the simultaneous demolding of the fused cast bricks in a plurality of mold boxes 3, greatly improving the operation efficiency.

[0035] Referring to Figure 1 , Figure 5 and Figure 6An auxiliary component is provided on the outside of the carriage 1, and the auxiliary component is used to open or close the top cover 2. The auxiliary component includes a fixed frame 12, the outside of the fixed frame 12 is fixedly connected to the outside of the carriage 1, the inside of the fixed frame 12 is rotatably connected with a wire-releasing drum 13, the outside of the wire-releasing drum 13 is sleeved with a pull rope 14, the outside of the fixed frame 12 is rotatably connected with a turntable 15, the outside of the turntable 15 is fixedly connected with a handle 16, one end of the turntable 15 is fixedly connected to one end of the wire-releasing drum 13, the outside of the carriage 1 is fixedly connected with a pulley 18, the top of the top cover 2 is fixedly connected with a connecting block 19, the outside of the pull rope 14 is slidably connected to the outside of the pulley 18, one end of the pull rope 14 is fixedly connected to the outside of the connecting block 19, a slot 20 is provided on the top of the fixed frame 12, a socket 23 is provided inside the handle 16, and the slot 20 and the inner wall of the socket 23 are plugged with an insertion rod 17, and the outer side of the insertion rod 17 is provided with anti-slip grooves.

[0036] Specifically, when opening the top cover 2, it is first necessary to pull out the rod 17 to disengage it from the slot 20 and the hole 23, so that the fixing relationship between the handle 16 and the fixed frame 12 is released, so that the turntable 15 can rotate, and then the handle 16 is held and rotated, thereby driving the turntable 15 to rotate together. The rotation of the turntable 15 further drives the pay-off reel 13 to rotate. The rotation of the pay-off reel 13 causes the pull rope 14 to be wound onto the pay-off reel 13, and the outer side of the pull rope 14 reduces friction through the pulley 18. As the pull rope 14 is wound, the connecting block 19 is pulled upward, thereby driving the entire top cover 2 to gradually open. When the top cover 2 is fully opened, the operator inserts the rod 17 into the slot 20 and the hole 23 again, and re-fixes the handle 16 to prevent the pay-off reel 13 from accidentally rotating when taking out the electric fused bricks, causing the top cover 2 to close, thereby ensuring safe operation.

[0037] Reference Figure 1 and Figure 2 A sealing groove 22 is provided on the top of the carriage 1 , and a sealing plate 21 is fixedly connected to the bottom of the top cover 2 , and the sealing plate 21 cooperates with the sealing groove 22 .

[0038] Specifically, when the carriage 1 is closed, the sealing plate 21 on the top cover 2 cooperates with the sealing groove 22 on the carriage 1, so that a closed annealing environment is formed, which helps to prevent the heat and gas generated during the annealing process from leaking into the external environment.

[0039] Working principle: When removing the electrofused bricks in the carriage 1, it is necessary to open the top cover 2. First, pull out the insertion rod 17 so that it disengages from the slot 20 and the jack 23. Then, rotate the handle 16 to drive the turntable 15 to rotate. The rotation of the turntable 15 causes the wire reel 13 to rotate, thereby winding up the pulling rope 14. The pulling rope 14 passes through the pulley 18 to reduce friction. At the same time, the pulling rope 14 pulls the connecting block 19 to open the top cover 2. After opening, insert the insertion rod 17 into the slot 20 and the jack 23 to fix the handle 16, preventing the wire reel 13 from rotating, so as to prevent the top cover 2 from closing when the staff removes the electrofused bricks and causing harm to the staff. When the carriage 1 is closed, the sealing plate 21 on the top cover 2 cooperates with the sealing groove 22 on the carriage 1, forming a closed annealing environment, which helps to prevent the heat and gas generated during the annealing process from leaking into the external environment. Then, start the electric telescopic rod 4, and extend its output end, so that it is transmitted to the gear 10 through the rack 5. Since the gear 10 meshes with the rack 5, the gear 10 will rotate accordingly. The rotation of the gear 10 drives the limiting block 7 to slide on the limiting rod 6 through the connecting rod 11. At the same time, the top of the limiting block 7 is connected to the push plate 9 through the connecting rod 8. Therefore, the push plate 9 will slide on the inner wall of the mold box 3. The sliding of the push plate 9 pushes the electrofused bricks in the mold box 3, realizing the simultaneous demolding of the electrofused bricks in multiple mold boxes 3, greatly improving the operation efficiency.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
