Abstract
Description
Technical Field
[0001] This utility model relates to the field of kiln car technology, and in particular to an ultra-high load-bearing kiln car for roasting lithium mica. Background Technology
[0002] Lepidolite is generally found only in granite pegmatites. It is purple or pink in color, ranging from light to colorless, and has a pearly luster. It occurs as short columnar crystals, small flake aggregates, or large plate-like crystals. Lepidolite contains several valuable metals such as lithium, rubidium, and cesium, which can be used to extract these metals.
[0003] Kiln cars are required during the calcination of lepidolite. A kiln car is the transport equipment in a tunnel kiln, and during operation, it must withstand the weight of the materials on board (including lining bricks and stacks) and the pushing force of the trolley. Kiln cars operate at high temperatures and are subject to repeated temperature changes; therefore, they must possess sufficient strength and heat resistance. Traditional tunnel kiln cars use a single-layer steel frame structure, which is sufficient for the load-bearing capacity of ordinary tunnel kilns. However, for ultra-wide tunnel kilns, kiln cars with higher load-bearing capacity are required. If this structure is still used, the kiln car will deform during use, and over time, it will collide with the curved joints of the kiln wall, affecting the normal operation of the kiln. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ultra-high load-bearing kiln car for calcining lithium mica.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A high-load-bearing kiln car for calcining lithium mica includes a support plate. Two upper support frames are provided at the bottom of the support plate, both located at the two ends of the bottom of the support plate. Upper reinforcing plates are intersected in the middle of the upper support frames, and multiple columns are vertically arranged at the bottom of the upper support frames and the upper reinforcing plates. A lower support frame is provided below the upper support frames, and lower reinforcing plates are intersected in the middle of the lower support frames. The tops of the lower support frames and the lower reinforcing plates are connected to the columns.
[0007] Furthermore, in a preferred configuration, the upper reinforcing plate in the middle of the upper support frame is inclined at a 45° angle, the lower reinforcing plate in the middle of the lower support frame is vertically arranged, and a column is connected to the middle of both the upper and lower reinforcing plates.
[0008] In addition, in a preferred configuration, multiple limiting posts are provided on the top of both the upper support frame and the upper reinforcing plate, and limiting cavities are provided on the bearing plate corresponding to the limiting posts, with the limiting posts passing through the limiting cavities and entering the upper part of the bearing plate.
[0009] In addition, in a preferred configuration, the number and position of the limiting posts correspond to the uprights, and the top of each limiting post is fitted with a sleeve above the bearing plate.
[0010] Furthermore, in a preferred configuration, mounting plates are provided downward on both sides of the lower support frame, and a support plate is provided between the mounting plates on both sides, with the support plate located below the middle of the lower support frame.
[0011] In addition, a preferred structure is that each mounting plate is provided with a mounting base below it, a rotating shaft is rotatably provided between the two mounting bases, and rollers are fixedly mounted on both ends of the rotating shaft.
[0012] In addition, a preferred structure is that multiple reinforcing mechanisms are provided between the lower reinforcing plate and the support plate, and the reinforcing mechanisms are arranged at an angle and cross each other.
[0013] In addition, a preferred structure is that multiple connecting mechanisms are provided between the upper support frames at both ends of the bottom of the bearing plate, and the connecting mechanisms are connected to the upper support frames and lower support frames on both sides.
[0014] In addition, a preferred structure is that both ends of the bearing plate are provided with feed inlets, and sealing sand plates are movably provided on each feed inlet.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-6 A high-load-bearing kiln car for calcining lithium mica includes a support plate 1. Two upper support frames 3 are provided at the bottom of the support plate 1. The two upper support frames 3 are located at both ends of the bottom of the support plate 1. Upper reinforcing plates 33 are intersected in the middle of the upper support frames 3. Multiple columns 4 are vertically arranged at the bottom of the upper support frames 3 and the upper reinforcing plates 33. A lower support frame 5 is provided below the upper support frames 3. Lower reinforcing plates 51 are intersected in the middle of the lower support frames 5. The tops of the lower support frames 5 and the lower reinforcing plates 51 are connected to the columns 4.
[0025] The upper reinforcing plate 33 in the middle of the upper support frame 3 is inclined at a 45° angle, while the lower reinforcing plate 51 in the middle of the lower support frame 5 is vertically arranged. A column 4 is connected to the middle of both the upper reinforcing plate 33 and the lower reinforcing plate 51. By setting the upper reinforcing plate 33 and the lower reinforcing plate 51 at different angles, the force on the bearing plate 11 can be distributed more evenly, thereby improving the bearing capacity of the bearing plate 11 and thus increasing the load-bearing capacity of the kiln car.
[0026] The upper support frame 3 and the upper reinforcing plate 33 are both equipped with multiple upward-facing limiting posts 31 at their tops. Each limiting post 31 on the bearing plate 1 has a corresponding limiting cavity, through which the limiting posts 31 pass and extend above the bearing plate 1. The limiting posts 31 enhance the connection stability between the upper support frame 3 and the bearing plate 1, thereby increasing the load-bearing capacity of the kiln car and preventing it from collapsing.
[0027] The number and position of the limiting posts 31 correspond to those of the upright posts 4, and each limiting post 31 has a sleeve 32 fitted on its top portion above the support plate 1. The sleeve 32 prevents material on the support plate 1 from leaking out through the limiting cavity. Furthermore, the corresponding arrangement of the limiting posts 31 to the upright posts 4 ensures a more even distribution of force on the support plate 11, thereby improving the load-bearing capacity of the support plate 11 and thus increasing the load-bearing capacity of the kiln car.
[0028] The lower support frame 5 has mounting plates 6 on both sides, and a support plate 61 is provided between the mounting plates 6 on both sides, with the support plate 61 located below the middle of the lower support frame 5. The mounting plates 6 and the support plate 61 strengthen the lower support frame 5, thereby improving the structural stability of the device.
[0029] Each mounting plate 6 has a mounting base 7 located below it, and a rotating shaft 71 is rotatably mounted between the two mounting bases 7. Rollers 72 are fixedly mounted on both ends of the rotating shaft 71. The mounting bases 7 allow the rotating shaft 71 to be installed, and the rotating shaft 71 drives the rollers 72 to rotate, thereby enabling the kiln car to move.
[0030] Multiple reinforcing mechanisms 52 are provided between the lower reinforcing plate 51 and the support plate 61, and the reinforcing mechanisms 52 are arranged at an angle and cross each other. By setting up the reinforcing mechanisms 52, the connection stability between the lower support plate 51 and the support plate 61 can be improved, thereby improving the stability of the chassis of this device and thus increasing the load-bearing capacity of this kiln car.
[0031] Multiple connecting mechanisms 8 are provided between the upper support frames 3 at both ends of the bottom of the bearing plate 1, and the connecting mechanisms 8 are connected to the upper support frames 3 and lower support frames 5 on both sides. By setting the connecting mechanisms 8, the upper support frames 3 and lower support frames 5 at both ends of the bottom of the bearing plate 1 can be connected, thereby improving the connection stability between the two support frames and thus enhancing the load-bearing capacity of the bearing plate 1.
[0032] The support plate 1 has inlets 2 at both ends, and sealing plates 21 are movably installed on each inlet 2. The inlets 2 allow lepidolite to be placed on the support plate 1, and the sealing plates 21 prevent the lepidolite from falling off the support plate 1.
[0033] In this invention, two upper support frames 3 are provided at the bottom of the bearing plate 1. Both upper support frames 3 are located at both ends of the bottom of the bearing plate 1. Upper reinforcing plates 33 are intersecting at the middle of the upper support frames 3, and multiple columns 4 are vertically arranged at the bottom of the upper support frames 3 and the upper reinforcing plates 33. The upper support frames 3 and the upper reinforcing plates 33 provide support for the bearing plate 1, thereby increasing its load-bearing capacity. The columns 4 connect the upper support frames 3 and the lower support frames 5, forming a complete support system that provides high-strength support for the bearing plate 11. A lower support frame 5 is provided below the upper support frames 3. Lower reinforcing plates 51 are intersecting at the middle of the lower support frame 5, and the tops of both the lower support frame 5 and the lower reinforcing plates 51 are connected to the columns 4. The lower reinforcing plates 51 improve the stability of the lower support frame 5. This allows the device to have a double-layer steel frame structure, with the upper layer being the load-bearing plate 1 and the lower layer being a support system consisting of the support frame 3, the column 4, and the lower support frame 5. This not only avoids increasing the mass of the kiln cars but also increases the load-bearing capacity of the kiln cars.
[0034] Furthermore, by setting the upper reinforcing plate 33 and the lower reinforcing plate 51 at different angles, the force distribution on the bearing plate 11 can be made more even. The setting of the limiting post 31 can improve the connection stability between the upper support frame 3 and the bearing plate 1. The setting of the sleeve 32 can prevent material on the bearing plate 1 from leaking out through the limiting cavity. And by setting the limiting post 31 corresponding to the column 4, the force distribution on the bearing plate 11 can be made more even, thereby improving the load-bearing capacity of the bearing plate 11 and thus increasing the load-bearing capacity of the kiln car.
[0035] Furthermore, the reinforcement mechanism 52 improves the connection stability between the lower support plate 51 and the support plate 61, thereby enhancing the stability of the chassis and increasing the load-bearing capacity of the kiln car. The connecting mechanism 8 connects the upper support frame 3 and the lower support frame 5 at both ends of the bottom of the bearing plate 1, improving the connection stability between the two support frames and thus increasing the load-bearing capacity of the bearing plate 1.
[0036] In this utility model, the user can place lithium mica material on the support plate 1. The sealing sand plate 21 can prevent the lithium mica material from falling. The support system composed of the upper support frame 3, the column 4 and the lower support frame 5 can support the support plate 1. The upper reinforcing plate 33 and the lower reinforcing plate 51 can improve the stability of the support system. The mounting plate 6 and the support plate 61 can improve the stability of the chassis of this device, thereby increasing the load-bearing capacity of the kiln car.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
