Gas dryer for flexible brick production

Abstract

This application discloses a gas dryer for flexible brick production, comprising a drying chamber assembly, the drying chamber assembly having a hot air output assembly inside. To address the problem in existing technologies where conventional hot air drying equipment for flexible bricks suffers from excessively strong hot air, excessively strong airflow at the outlet, or chaotic airflow organization, resulting in significant material impact on the lightweight, not fully dried and cured flexible brick surface, causing slight bending and warping, this application designs a hot air output assembly with a flow-guiding structure. This flow-guiding structure allows for dispersed airflow output through diffusion, and the angle can be intermittently adjusted, avoiding the problem of continuous impact force from a single location due to overly concentrated or unidirectional airflow. This design is particularly suitable for use with flexible bricks.

Description

Technical Field

[0001] This application relates to the field of brick drying equipment technology, and in particular to a gas dryer for the production of flexible bricks. Background Technology

[0002] Flexible facing bricks are a new type of building decoration material that imitates the appearance and texture of traditional ceramic facing bricks or stone, but has very good flexibility and elasticity. In the production process of flexible facing bricks, hot air drying is a key curing process.

[0003] Traditional equipment has a concentrated hot air output. The air force intensity at the air outlet is too high or the airflow organization is disordered, which will generate a continuous local impact on the surface of flexible bricks. Since the structural strength of flexible bricks is low in the early stage of drying, such impacts can easily cause irreversible deformation such as bending of the board surface and edge warping, which directly affects the product qualification rate. For example, ordinary air ducts or narrow slit air outlets have insufficient airflow diffusion, which causes the local wind speed to exceed the material's tolerance threshold.

[0004] In other words, existing technologies have the following technical problems: ordinary brick drying equipment is prone to warping of flexible bricks due to continuous airflow impact during hot air drying. Therefore, a gas dryer for flexible brick production is proposed to address the above problems. Summary of the Invention

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] Please see Figure 1-4 As shown, a gas dryer for flexible brick production includes:

[0030] Drying chamber assembly 1, wherein a hot air output assembly 2 is provided inside the drying chamber assembly 1, the hot air output assembly 2 is used to output hot air to dry the bricks, and the air outlet end of the hot air output assembly 2 is provided with a flow guide structure.

[0031] The brick support component 3 is fixedly installed in the inner cavity of the drying chamber component 1. The brick support component 3 is connected to the hot air output component 2. The brick support component 3 is used to support the bricks and automatically drive the bricks to move slowly during hot air drying.

[0032] Through the above technical solution, by setting the airflow guide structure, the airflow can be dispersed and output through diffusion, and the angle can be adjusted intermittently, avoiding the problem of continuous impact force in a single position caused by the air outlet being too concentrated or the direction being unidirectional. It is particularly suitable for use with flexible bricks.

[0033] The drying chamber assembly 1 includes a drying chamber 101 and a chamber door 102. The chamber door 102 is hinged to the side of the drying chamber 101, and a door lock is installed between the drying chamber 101 and the chamber door 102.

[0034] The hot air output assembly 2 includes an output shell 201 and a flow guiding structure. The output shell 201 is fixedly installed on the upper wall of the inner cavity of the drying chamber 101. One end of the hot air pipe 103 is fixedly connected to the inner cavity of the output shell 201. The other end of the hot air pipe 103 penetrates the inner wall of the drying chamber 101 and extends to the outside of the wall. An air outlet is provided on the bottom side of the inner cavity of the output shell 201, and a flow guiding structure is provided at the air outlet.

[0035] The airflow guiding structure includes an air guide plate 202, a rotating rod 204 and a driving unit. The rotating rod 204 is located on the side wall of the air outlet of the output shell 201 and is rotatably connected to the output shell 201. The air guide plate 202 is fixedly connected to the rotating rod 204. One end of the rotating rod 204 penetrates the inner wall of the drying chamber 101 and extends to the outside of the wall.

[0036] The air guide plate 202 has several air holes 203. The diameter of the air holes 203 is preferably 5mm, and they are evenly distributed in a grid with a spacing of 10mm. The total number of holes is 100-200. The material is heat-resistant stainless steel. It effectively disperses the airflow and reduces the impact. In use, the hot air pipe is connected to the hot air equipment. The hot air is input into the inner cavity of the output shell 201 through the hot air pipe 103. Then the hot air flow is dispersed and output through the air holes 203, thereby avoiding the phenomenon of excessive impact caused by the output airflow being too concentrated. This disperses the airflow and ensures the uniformity of drying.

[0037] The drive unit includes a swing frame 205, a connecting rod 206, a rotating gear 207, and a rotating shaft 208. The swing frame 205 is fixedly mounted at one end of the rotating rod 204, and the other end of the swing frame 205 is rotatably connected to the connecting rod 206. The rotating shaft 208 is located on the outer wall of the drying chamber 101 and is rotatably connected to the drying chamber 101. One end of the connecting rod 206 extends to the side wall of the rotating gear 207 and is rotatably connected to the rotating gear 207. Through this technical solution, the rotation of the rotating gear 207 can drive the bottom end of the connecting rod 206 to move in a ring, thereby driving the upper end of the connecting rod 206 to move up and down reciprocally. This can drive the swing frame 205 to swing back and forth, thereby driving the rotating rod 204 to rotate back and forth, and thus driving the air guide plate 202 to rotate back and forth. Through continuous reciprocating rotation and swing, the hot airflow is prevented from being output in a single direction for a long time, thereby greatly reducing the phenomenon of continuous impact damage to the flexible panel caused by continuous output from the same position.

[0038] A fixed bracket 209 is fixedly connected to the side wall of the drying chamber 101. A drive motor 210 is fixedly connected to the fixed bracket 209. A drive gear 211 is fixedly connected to the end of the output shaft of the drive motor 210. The drive gear 211 meshes with the rotating gear 207. Through this technical solution, the operation of the drive motor 210 can drive the drive gear 211 to rotate, thereby driving the rotating gear 207 to rotate.

[0039] The brick bearing assembly 3 includes a bearing part 301, a support base 302, a first rotating rod 303, and a linkage part. The support base 302 is fixedly installed in the inner cavity of the drying chamber 101. The upper end of the support base 302 is rotatably connected to the turntable of the bearing part 301 with a diameter of 1.2m. The support base 302 has an inner cavity. The first rotating rod 303 is rotatably connected in the inner cavity of the support base 302. The top end of the first rotating rod 303 is fixedly connected to the bottom surface of the bearing part 301.

[0040] The linkage part includes a first bevel gear 304, a second bevel gear 305, a second rotating rod 306, and a linkage gear 307. The first bevel gear 304 is fixedly disposed at the arc-shaped wall of the first rotating rod 303. The second rotating rod 306 is rotatably connected in the inner cavity of the support base 302. One end of the second rotating rod 306 is fixedly connected to the second bevel gear 305. The second bevel gear 305 and the first bevel gear 304 mesh with each other. The other end of the second rotating rod 306 penetrates the inner cavity side wall of the drying chamber 101 and extends to the outside of the wall. One end of the second rotating rod 306 is fixedly connected to the linkage gear 307.

[0041] The number of teeth of the linkage gear 307 is much greater than the number of teeth of the rotating gear 207. The linkage gear 307 and the rotating gear 207 mesh with each other. Through this technical solution, when the rotating gear 207 rotates, it can drive the linkage gear 307 to rotate slowly, thereby driving the second rotating rod 306 to rotate. Through the transmission of the second bevel gear 305, the first bevel gear 304 and the first rotating rod 303, the bearing part 301 rotates. Through the slow rotation of the bearing part 301, the placed bricks can rotate slowly, thereby making the hot air drying more uniform and effectively avoiding the warping and deformation caused by continuous blowing and impact from a single position and a single wind direction.

[0042] As a specific embodiment: the drive motor 210 is a stepper motor with a speed of 20 RPM; the rotating gear 207 has 20 teeth, the drive gear 211 has 10 teeth, and the linkage gear 307 has 100 teeth; when the drive motor 210 starts, the rotating gear 207 rotates 72° for every revolution, thereby causing the bearing part 301 to rotate slowly, so that the brick is heated evenly and is not affected by centrifugal force. The linkage is controlled by PLC. After the machine is turned on, the hot air output component 2 preheats for 2 minutes, and then starts swinging and rotating. Under this setting, the airflow is output evenly, ensuring that the surface of the brick is not bent or warped.

[0043] A centrifugal exhaust fan is installed at the bottom of the drying chamber 101 for exhaust gas discharge.

[0044] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
