Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a drying device for refractory brick production. Background Technology

[0002] Refractory materials are generally divided into two types: unshaped refractories and shaped refractories. Unshaped refractories, also known as castables, are mixed powdery granules composed of various aggregates and one or more binders. They must be mixed with one or more liquids and stirred evenly before use, and have strong fluidity. Shaped refractories generally refer to refractory bricks, which have standard and regular shapes, but can also be temporarily processed during construction as needed. Generally, after the refractory bricks are produced and shaped, they need to be dried to remove the moisture contained within them and ensure the production quality of the refractory bricks.

[0003] Existing drying methods fix the position of refractory bricks during drying because many traditional drying devices use fixed brick racks. These racks are often designed to be fixed and make it difficult to adjust the distance between multiple racks, thus limiting the positional movement of the refractory bricks during the drying process. Furthermore, due to structural limitations, some drying devices are designed so that once placed, the refractory bricks are difficult to move. For example, some devices use guide rails and limiting blocks to restrict the placement of the refractory bricks. While this ensures structural tightness and ease of handling, it also results in a fixed position. This leads to refractory bricks closer to the heat source receiving better heat than those farther away, resulting in uneven drying within the same batch and consequently reducing the overall quality of the batch. Therefore, a drying device for refractory brick production that achieves uniform drying is needed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4This utility model provides a new technical solution: a drying device for refractory brick production, including a concave support frame 1, two L-shaped fixing plates 2 are fixedly connected to the upper surface of the concave support frame 1, a circular drying box 3 is fixedly connected to the opposite face of the two L-shaped fixing plates 2, and a feeding device is set on the concave support frame 1.

[0031] A drying assembly is provided on a circular drying chamber 3. The drying assembly includes an L-shaped mounting plate 9, which is fixedly connected to the upper surface of the circular drying chamber 3.

[0032] Among them, the rear surface of the L-shaped mounting plate 9 is fixedly connected to the connecting pipe 6, and the lower surface of the connecting pipe 6 is rotatably connected to the transmission pipe 4, which is connected to the connecting pipe 6.

[0033] The lower end of the transmission tube 4 rotates and penetrates into the interior of the circular drying box 3, and the outer wall of the transmission tube 4 is fixedly sleeved with the first gear 5.

[0034] Among them, a servo motor 15 is fixedly installed on the upper surface of the circular drying oven 3, and a second gear 17 is fixedly connected to the output end of the servo motor 15. The second gear 17 meshes with the first gear 5.

[0035] Furthermore, the drying assembly also includes a heating fan 8, which is fixedly connected to the upper surface of the circular drying box 3, and an air supply pipe 7 is fixedly installed at the air outlet of the heating fan 8.

[0036] Among them, the end of the gas supply pipe 7 away from the heating fan 8 is fixedly connected to the connecting pipe 6, and the gas supply pipe 7 and the connecting pipe 6 are connected.

[0037] Furthermore, the drying assembly also includes four conveying pipes 18, all of which are fixedly connected to the outer surface of the transmission pipe 4 and communicate with the transmission pipe 4. The lower surfaces of the four conveying pipes 18 are all fixedly connected with multiple air outlets 19 that communicate with them.

[0038] Furthermore, the feeding device includes a concave mounting plate 11, which is fixedly connected to the lower surface of the concave support frame 1. A multi-stage cylinder 10 is fixedly installed in the concave part of the concave mounting plate 11, and the telescopic end of the multi-stage cylinder 10 slides through the upper surface of the concave support frame 1.

[0039] Furthermore, the telescopic end of the multi-segment cylinder 10 slides through the upper surface of the concave support frame 1, and the telescopic end of the multi-segment cylinder 10 is fixedly connected to a lifting plate 13. The lifting plate 13 is slidably connected to the inner wall of the circular drying oven 3, and four guide rods 12 are fixedly connected to the lower surface of the lifting plate 13.

[0040] Furthermore, the lower ends of the four guide rods 12 slide through the lower surface of the concave support frame 1, and a circular groove 16 is provided on the upper surface of the lifting plate 13.

[0041] Furthermore, multiple heating plates 20 are fixedly installed at the bottom of the circular groove 16, and a placement plate 14 is fixedly connected to the inner wall of the circular groove 16.

[0042] Furthermore, when using the drying device for refractory brick production, the workers first place multiple refractory bricks on the placement plate 14 using external tools;

[0043] Once the placement is complete, the multi-stage cylinder 10 is activated. The telescopic end of the multi-stage cylinder 10 pushes the lifting plate 13 upward, causing the lifting plate 13 to enter the inner wall of the circular drying oven 3.

[0044] In this process, the lifting plate 13 moves, which drives multiple guide rods 12 to move. The multiple guide rods 12 play an auxiliary role in the movement of the lifting plate 13.

[0045] Then, the heating fan 8 is started, and the heating fan 8 delivers the generated hot air through the air supply pipe 7, the connecting pipe 6 and the placement plate 14 to the inside of the four supply pipes 18, and then discharges it through multiple air outlets 19, blowing it toward multiple refractory bricks.

[0046] In this process, multiple heating plates 20 are activated simultaneously to heat the lifting plate 13. The lifting plate 13 then transfers heat to the lower surface of multiple refractory bricks, thereby drying the lower surface of the multiple refractory bricks.

[0047] The process involves starting the servo motor 15, which drives the second gear 17 to rotate. The second gear 17 then drives the transmission pipe 4 to rotate via the first gear 5, which in turn drives the four conveying pipes 18 and multiple air outlets 19 to rotate. This allows hot air to be blown evenly onto the top of the multiple refractory bricks, drying the upper surface of the bricks uniformly. The heated lifting plate 13 then dries the lower surface of the bricks, resulting in uniform and rapid drying of the refractory bricks and improving the overall quality of the refractory bricks produced in the same batch.

[0048] After drying, the multi-stage cylinder 10 is reset, and the multi-stage cylinder 10 drives the lifting plate 13 to move downward, so that the lifting plate 13 is separated from the circular drying box 3, making it convenient for the staff to take out the dried refractory bricks. The feeding device is set to facilitate the staff to pick up and put down the refractory bricks, prevent the high temperature inside the circular drying box 3 from affecting the staff, and thus improve the convenience of the staff to load and unload the refractory bricks.
