Description

Technical Field

[0001] This utility model relates to the field of kiln technology, and more specifically, to an automated temperature-controlled kiln system for magnesia brick production. Background Technology

[0002] In the production of magnesia bricks, precise control of kiln temperature has always been a key factor affecting the quality and production efficiency of magnesia bricks. The kiln is a piece of equipment made of refractory materials used to fire products and is an essential facility in the molding of magnesia bricks.

[0003] Currently, the air intake methods for kilns are relatively simple, usually relying on natural ventilation through fixed ventilation ducts or a single fan for air supply. This makes it impossible to flexibly adjust the air intake according to actual production needs. The oxygen input is controlled by simple valves, which cannot meet the different oxygen content requirements at different production stages. This makes it difficult to obtain a precise air supply for the combustion reaction in the kiln, resulting in incomplete combustion, wasting energy, and affecting the firing quality of magnesia bricks. Moreover, since the air intake and oxygen supply are not adjustable, it is difficult to quickly and effectively control the temperature environment inside the kiln when the temperature changes.

[0009] Preferably, the outer surface of the fixed box is provided with multiple vent holes, a connecting rod is fixedly connected to the outer side of the rotating shaft, and a baffle plate is fixedly connected to one end of the connecting rod.

[0010] Preferably, a connecting column is fixedly connected to one side of the kiln body, and a fixing sleeve is fixedly connected to one end of the connecting column, and the fixing sleeve is fixedly connected to the oxygen tank.

The microcontroller issues precise control commands to the motor and stepper motor according to the preset temperature range, realizing precise regulation of the air intake and oxygen volume. This enables accurate control of the temperature inside the kiln, ensuring that magnesia bricks are produced under suitable temperature conditions, avoiding insufficient air and incomplete combustion that affects the quality of magnesia bricks, and improving the production quality of magnesia bricks. The temperature can be flexibly adjusted according to different production stages and process requirements to meet various temperature requirements in the magnesia brick production process.

[0015] 2. By sending air to the bottom of the kiln body through the air inlet pipe via a blower, sufficient air is provided for combustion, ensuring the full combustion reaction, improving fuel combustion efficiency, and reducing energy consumption. The temperature control process of the entire system is automatically completed by a single-chip microcomputer without manual intervention, which greatly reduces the workload of operators and improves production efficiency.

[0025] The air intake adjustment mechanism includes an air intake pipe 2, which is fixed to the bottom of the kiln body 1. A fan 3 is fixedly installed at one end of the air intake pipe 2. A fixed housing 4 is fixedly connected to the front side of the air intake pipe 2. A motor 5 is fixedly installed at the front side of the fixed housing 4. A threaded rod 6 is fixedly connected to the output end of the motor 5. A movable plate 7 is provided at one end of the threaded rod 6. A threaded hole 8 is opened on one side surface of the movable plate 7. A microcontroller 19 is fixedly installed on one side of the kiln body 1. A temperature sensor 20 is fixedly installed on the top of the kiln body 1.

[0026] As attached Figure 1-5As shown, the oxygen regulating mechanism includes an oxygen tank 9, which is located on one side of the kiln body 1. A gas supply pipe 10 is fixedly connected to the bottom of the oxygen tank 9. The bottom of the gas supply pipe 10 passes through the air inlet pipe 2 and extends into the air inlet pipe 2. A stepper motor 12 is fixedly installed on the front side of the air inlet pipe 2. A fixed box 11 is fixedly connected to the bottom of the gas supply pipe 10. A rotating shaft 13 is fixedly connected to the output end of the stepper motor 12. The rotating shaft 13 is rotatably connected to the fixed box 11. The fixed box 11 is fixedly installed inside the air inlet pipe 2. Multiple exhaust holes 14 are opened on the outer surface of the fixed box 11. A connecting rod 15 is fixedly connected to the outside of the rotating shaft 13. A baffle plate 16 is fixedly connected to one end of the connecting rod 15, so that by adjusting the angle of the baffle plate 16, the baffle plate 16 can block part of the exhaust holes 14, thereby achieving the effect of regulating the oxygen content discharged into the air inlet pipe 2.

[0027] As attached Figure 1 , 2 As shown, a connecting column 17 is fixedly connected to one side of the kiln body 1, and a fixing sleeve 18 is fixedly connected to one end of the connecting column 17. The fixing sleeve 18 is fixedly connected to the oxygen tank 9 to ensure the stability of the oxygen tank 9.

[0028] As attached Figure 1 , 2 As shown, the bottom of the temperature sensor 20 penetrates through the kiln body 1 and extends into the interior of the kiln body 1. The temperature sensor 20, the stepper motor 12, and the motor 5 are all electrically connected to the microcontroller 19. A base 21 is fixedly installed at the bottom of the kiln body 1 to facilitate the microcontroller 19 in controlling the internal temperature of the kiln body 1 and ensuring the stability of the kiln body 1.

[0029] As attached Figure 6 As shown, limit grooves 22 are provided on the top and bottom surfaces of the inner wall of the fixed shell 4.

[0030] Working principle of this utility model: During use, the blower 3 delivers air to the bottom of the kiln body 1 through the air inlet pipe 2 to provide the air required for combustion. The motor 5 drives the threaded rod 6 to rotate. The threaded hole 8 on one side of the moving plate 7 cooperates with the threaded rod 6. As the threaded rod 6 rotates, the moving plate 7 moves inside the fixed shell 4. By moving the moving plate 7, the air intake volume of the air inlet pipe 2 can be adjusted. Oxygen in the oxygen tank 9 enters the fixed box 11 through the gas delivery pipe 10. The stepper motor 12 drives the rotating shaft 13 to rotate. The connecting rod 15 and the baffle plate 16 on the outside of the rotating shaft 13 rotate accordingly. During the rotation of the baffle plate 16, it blocks the exhaust holes 14 on the outer surface of the fixed box 11 in turn. By adjusting the number of exhaust holes 14 blocked by the baffle plate 16, the amount of oxygen discharged from the exhaust holes 14 can be controlled, thereby adjusting the oxygen content in the kiln and realizing the control of the kiln temperature.

[0031] Temperature sensor 20 is installed on the top of kiln body 1, with its bottom penetrating the interior of kiln body 1. It monitors the temperature inside the kiln in real time. Temperature sensor 20 transmits the monitored temperature data to microcontroller 19. Microcontroller 19 issues control commands to motor 5 and stepper motor 12 according to the preset temperature range. If the temperature is too high, microcontroller 19 may control motor 5 to reduce the air intake of air inlet pipe 2, and at the same time control stepper motor 12 to rotate baffle plate 16 to reduce the amount of oxygen. If the temperature is too low, microcontroller 19 may control motor 5 to increase the air intake of air inlet pipe 2, and at the same time control stepper motor 12 to rotate baffle plate 16 to increase the amount of oxygen, thereby achieving the temperature control effect.
