Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of autoclaved brick production, and more specifically, to a drying apparatus for autoclaved brick production. Background Technology
[0002] In the production process of autoclaved bricks, drying is a crucial step in ensuring product performance. After autoclaving, the bricks contain a large amount of moisture, which needs to be removed through drying to prevent cracking and deformation during subsequent storage or use, while also enhancing the structural stability and strength of the bricks.
[0003] However, existing drying equipment for autoclaved brick production has significant drawbacks, particularly in the feeding and discharging stages. Traditional drying equipment often uses a fixed cavity structure, requiring manual stacking of wet bricks onto the drying racks one by one during feeding, which is cumbersome and inefficient. Discharging also relies on manual handling, which is not only labor-intensive but also increases the risk of burns to operators due to the high temperature of the bricks. Although some equipment has attempted to use conveyor belts, the varying sizes and weights of the autoclaved bricks cause the conveyor belts to jam or deviate, leading to interruptions in feeding and discharging. Furthermore, the narrow inlet and outlet designs of traditional equipment, coupled with poor sealing between them and the drying cavity, easily cause collisions and damage to wet bricks during feeding and result in significant heat loss during discharging, increasing energy consumption and prolonging the drying cycle.
[0004] This inconvenient material feeding and discharging method makes the drying process a bottleneck in the large-scale production of autoclaved bricks, reducing overall production efficiency and increasing production costs due to excessive manual intervention. With the construction industry's increasing demands for autoclaved brick capacity and quality, there is an urgent need for a drying device that facilitates material feeding and discharging to optimize the production process, reduce energy consumption, and improve production safety. Utility Model Content

[0011] As a further technical solution, the material rack is composed of multiple layers of boards, and each layer of the material rack has several ventilation holes on its surface. Inclined platforms are provided on both sides of the fixed plate.
[0012] As a further technical solution, the enclosed heating assembly includes a gantry frame, which is fixed to the fixed plate and located on the top of the housing. A pair of cylinders are horizontally mounted on the gantry frame.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:
[0019] 1. In this disclosure, the material placement assembly, through the cooperation of moving wheels, positioning frames, and multi-layer material placement racks, solves the problem of traditional devices relying on manual handling for material feeding and discharging.

[0032] like Figures 1-3 The diagram illustrates a drying apparatus for autoclaved brick production according to an embodiment of this disclosure, comprising:
[0033] The base plate 1, the fixing plate 2, and the outer shell 3 are provided. The fixing plate 2 is fixed on the base plate 1, and the outer shell 3 is slidably connected to the base plate 1.
[0034] Material placement component 4 is disposed on the base plate 1;
[0035] A closed heating assembly 5 is disposed on the outer casing 3;
[0036] The material placement assembly 4 includes a material placement rack 4-1. Support legs 4-2 are provided at the four opposite corners of the bottom of the material placement rack 4-1. Movable wheels 4-3 are installed inside the bottom of each support leg 4-2. A pair of positioning frames 4-4 are provided on the surface of the fixed plate 2. The support legs 4-2 and the movable wheels 4-3 are located in the positioning frames 4-4. The material placement rack 4-1 is composed of multiple layers of boards. Several ventilation holes 4-5 are opened on the surface of each layer of the material placement rack 4-1. Inclined platforms 4-6 are provided on both sides of the fixed plate 2.
[0037] In some examples, to achieve batch feeding and unloading, a material placement assembly 4 is designed. This assembly includes a material placement rack 4-1 with four vertically fixed support legs 4-2 at its bottom corners. Embedded casters 4-3 at its bottom are rotatably connected via bearings, allowing the rack to move on the bottom surface and providing flexible mobility. A pair of positioning frames 4-4 on the surface of the fixing plate 2 have a U-shaped structure with upward openings. The support legs 4-2 and casters 4-3 are precisely accommodated within these frames. The inner walls of the positioning frames 4-4 are tightly fitted to the support legs 4-2, restricting the horizontal displacement of the material placement rack 4-1 and ensuring its stable placement.
[0038] The material rack 4-1 is made of multiple layers of stacked boards. Ventilation holes 4-5 are evenly distributed on the surface of each layer of boards to provide channels for hot air, ensuring that all parts of the autoclaved bricks can fully contact the hot air. The inclined platforms 4-6 on both sides of the fixed plate 2 face the direction of movement of the material rack 4-1. When the material rack 4-1 needs to be pushed into the drying area, the moving wheels 4-3 can smoothly roll along the inclined platforms 4-6, reducing the difficulty of manual pushing. When discharging, the inclined platforms 4-6 can also assist the material rack 4-1 to move out smoothly.
[0039] In practical operation, the unloaded material rack 4-1 can be easily moved to the loading area via the casters 4-3. After loading the autoclaved bricks, it can be pushed back into the positioning frame 4-4 on the fixed plate 2. At this time, the positioning frame 4-4 ensures that the material rack 4-1 will not shake or shift during the drying process. Due to the multi-layer design of the material rack 4-1 and the layout of the ventilation holes 4-5, a large number of autoclaved bricks can be stored at one time, and hot air can circulate between the layers through the ventilation holes 4-5, achieving efficient feeding and unloading of batch materials and uniform heating, thus meeting the high-efficiency requirements of the drying process in autoclaved brick production.
[0040] like Figures 1-3As shown in the figure, the enclosed heating assembly 5 in this embodiment includes a gate-shaped frame 5-1, which is fixed on the fixed plate 2. The gate-shaped frame 5-1 is located at the top of the outer shell 3. A pair of cylinders 5-2 are horizontally installed on the gate-shaped frame 5-1. The output end of the cylinders 5-2 is fixedly connected to the top of the outer shell 3. Several heat dissipation plates 5-3 are provided on the inner wall of the outer shell 3. Several heating tubes 5-4 are installed in each of the heat dissipation plates 5-3.
[0041] In some examples, to achieve uniform heat transfer during drying, a closed heating assembly 5 is designed. This assembly includes a gantry frame 5-1 fixed to a fixed plate 2, spanning above the outer shell 3. A pair of horizontally mounted cylinders 5-2 are provided on the side surface of the gantry frame 5-1 to provide a stable support base. The cylinder body of the cylinder 5-2 is fixed to the gantry frame 5-1, and its output end is fixed to the top of the outer shell 3 by a connector, which can drive the outer shell 3 to slide along the base plate 1, realizing the opening and closing of the outer shell 3, facilitating the entry and exit of the material placement assembly 4.
[0042] The heat dissipation plate 5-3, fixed to the inner wall of the outer shell 3, is made of a metal with good thermal conductivity to ensure uniform heat dissipation. Several heating tubes 5-4 installed in each heat dissipation plate 5-3 are connected to an external power source via an electrical circuit. When energized, they generate heat, which is conducted through the heat dissipation plate 5-3 to the interior space of the outer shell 3. When the outer shell 3 is closed by the cylinder 5-2, a closed drying space is formed. The heat generated by the heating tubes 5-4 is evenly distributed under the action of the heat dissipation plate 5-3, preventing localized overheating or overcooling. Furthermore, the heat dissipation plate 5-3 is interspersed within the shelf.
[0043] During the drying process, cylinder 5-2 first opens the outer shell 3, and after the material placement component 4 is in place, it pushes the outer shell 3 to close. Subsequently, heating tube 5-4 starts heating, and the heat is evenly distributed into the outer shell 3 through heat dissipation plate 5-3, drying the autoclaved bricks on the material placement rack 4-1. The closed heating component 5, through the coordinated work of the gantry frame 5-1, cylinder 5-2, heat dissipation plate 5-3, and heating tube 5-4, achieves closed heating and drying of the autoclaved bricks. Its uniform heat distribution ensures the consistency of the drying quality of the autoclaved bricks, while the opening and closing design of the outer shell 3 facilitates the loading and unloading of materials, improving the overall working efficiency of the drying device.
[0044] For example, such as Figure 1 As shown, the heat sink 5-3 has a hollow structure.
[0045] In some examples, the perforated structure of the heat sink 5-3 enhances heat transfer efficiency. The perforations form ventilation channels, allowing the heat generated by the heating tube 5-4 to quickly diffuse into the interior of the outer casing 3. Simultaneously, it promotes the circulation of hot air between the heat sinks 5-3, preventing localized heat accumulation and resulting in a more uniform temperature distribution within the outer casing 3. This improves the consistency of autoclaved brick drying and also reduces the weight of the heat sink 5-3 itself, lowering the installation load-bearing pressure.
[0046] For example, such as Figure 3 As shown, the outer surface of the fixing plate 2 has a stepped structure around its perimeter.
[0047] In some examples, the stepped structure on the outer surface of the fixing plate 2 is adapted to the inner wall of the outer shell 3. When the outer shell 3 is closed, the stepped structure forms a tight-fitting seal with the edge of the outer shell 3, reducing heat loss from gaps and enhancing the sealing performance of the outer shell 3. This design improves heat utilization efficiency, shortens drying time, and avoids direct hard contact between the outer shell 3 and the fixing plate 2, reducing wear caused by impact.
[0048] For example, such as Figure 1 As shown, handles are provided on both sides of the material rack 4-1.
[0049] In some examples, the handles on both sides of the material rack 4-1 are fixed by welding, and their surfaces are provided with anti-slip textures. The handles provide a point of force for the operator to push the material rack 4-1, and the anti-slip textures increase hand friction, making it easier to apply force. Whether pushing the material rack 4-1 into the positioning frame 4-4 or removing it from the fixed plate 2, the handles make operation more effortless and convenient, improving the efficiency of the material loading and unloading operation of the material loading assembly 4.
[0050] For example, such as Figure 2 As shown, the two side surfaces of the support leg 4-2 slide against the inner wall of the positioning frame 4-4, and the positioning frame 4-4 has a single-sided opening structure.
[0051] In some examples, the two side surfaces of the support leg 4-2 slide against the inner wall of the positioning frame 4-4, with one side opening of the positioning frame 4-4 facing the direction of movement. This structure allows the support leg 4-2 to slide precisely along the inner wall of the positioning frame 4-4, ensuring that the material rack 4-1 smoothly enters the designated position. The one-sided opening design facilitates the entry and exit of the material rack 4-1 while restricting the movement of the support leg 4-2 in other directions, enhancing the stability of the material rack 4-1 during the drying process and preventing shaking.
[0052] In practical use: The base plate 1 is fixed. The positioning frame 4-4 on the fixing plate 2 has a single-sided opening structure. Pushing the handles on both sides of the material rack 4-1 causes the moving wheels 4-3 at the bottom of the support legs 4-2 to slide along the inclined platform 4-6 into the positioning frame 4-4. The support legs 4-2 are positioned against the inner wall of the positioning frame 4-4. The autoclaved bricks are layered and placed on the multi-layered plates of the material rack 4-1. The cylinder 5-2 on the portal frame 5-1 drives the outer shell 3 to slide along the base plate 1, forming a closed space. The closed heating component 5 is activated. The heat generated by the heating tube 5-4 is evenly diffused through the perforated heat dissipation plate 5-3. Hot air circulates between layers through the vent holes 4-5 of the material rack 4-1, drying the bricks. After drying, the cylinder 5-2 pulls the outer shell 3 open. The material rack 4-1 is slid out along the positioning frame 4-4 using the handles, completing the unloading process. The stepped structure of the fixing plate 2 enhances the sealing of the outer shell 3, reducing heat loss.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
