[0002] As an important component of tunnel kilns, the kiln tail plays a crucial role in product cooling and heat recovery. With technological advancements and increasingly stringent environmental requirements, the design and application of tunnel kiln tails will continue to be optimized and improved. The tail section of a high-temperature tunnel kiln serves as the discharge zone for the fired products. The fired products experience minimal temperature loss when transported from the high-temperature section to the tail section, maintaining a consistently high temperature.

[0003] The cleaning device still has the following drawbacks: when the finished product is discharged, the staff needs to wait for the tail of the tunnel kiln to cool down before the material can be discharged, which takes a long time and affects work efficiency. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figures 1-8 This utility model provides an embodiment of a novel tunnel kiln tail cooling device, comprising a tunnel kiln body 1, a motor 2 fixedly connected inside the tunnel kiln body 1, a pulley 3 fixedly connected to the output end of the motor 2, a high-temperature resistant belt 4 mounted on the pulley 3, a pulley 5 mounted at one end of the high-temperature resistant belt 4, a slider 6 fixedly connected to the high-temperature resistant belt 4, a slider 7 fixedly connected below the high-temperature resistant belt 4, an isolation door 8 rotatably connected below the slider 6, an isolation door 10 rotatably connected at one end of the isolation door 8, and an isolation door 9 rotatably connected below the slider 7. The tunnel kiln body 1 is connected to an isolation door 4 11. A slide rod 12 is fixedly connected inside the tunnel kiln body 1. By turning on the motor 2, the pulley 1 3, the high-temperature belt 4, and the pulley 2 5 are driven to rotate. This causes the slider 1 6 and slider 2 7 on the high-temperature belt 4 to move in opposite directions. This causes the isolation door 1 8 and isolation door 2 9 to come into contact with each other. The isolation door 1 8, isolation door 2 9, isolation door 3 10, and isolation door 4 11 separate the middle and tail of the tunnel kiln body 1. This prevents cold air from entering the middle of the tunnel during the cooling process of the tail of the tunnel kiln body 1, thus preventing the tail of the tunnel kiln from cooling and affecting the quality of the products in the middle of the tunnel kiln.

[0033] The tunnel kiln body 1 is equipped with a fan 13, a ventilation opening 14 is fixedly connected to one end of the tunnel kiln body 1, a fixed column 15 is fixedly connected to the ventilation opening 14, a rotating plate 16 is rotatably connected to the fixed column 15, a rotating plate 17 is rotatably connected to the fixed column 15, a guide column 18 is fixedly connected to the rotating plate 16, a guide column 19 is fixedly connected to the rotating plate 17, an electric telescopic rod 20 is fixedly connected to the ventilation opening 14, a guide rod 21 is fixedly connected to the output end of the electric telescopic rod 20, and a cooler 22 is fixedly connected to the tunnel kiln body 1. The model is FM-125-20-2. A cooling fan 22 has a fixed air collection box 23 connected to one side, and a guide pipe 24 is fixedly connected below the air collection box 23. A tunnel kiln door 25 is slidably connected to one side of the tunnel kiln body 1. A fixing block 1 26 is fixedly connected to the tunnel kiln door 25. A fixing block 27 is fixedly connected to one side of the tunnel kiln body 1. A locking pin 28 is rotatably connected to the fixing block 27. Belt pulleys 1 3 and 2 5 are rotatably connected inside the tunnel kiln body 1. Sliding blocks 1 6 and 2 7 are slidably connected to the sliding rod 12. Isolation doors 3 10 and 4 11 are rotatably connected... The bottom ends of isolation doors 1 (8) and 2 (9) are slidably attached to the tunnel kiln body 1. A sliding rod 12 is positioned above isolation doors 1 (8), 2 (9), 3 (10), and 4 (11). A ventilation opening 14 is located on one side of a fan 13. A guide pipe 24 runs through the top of the tunnel kiln body 1. A fixing block 1 (26) is attached to a fixing block 2 (27). One end of a locking post 28 is attached to one side of a fixing block 1 (26). A guide rod 21 slides above the ventilation opening 14. Guide posts 1 (18) and 2 (19) are attached to the guide rod 21. Four sets of guide pipes 24 are provided, which are electrically controlled. The telescopic rod 20 moves the guide column 18 and guide column 2 19, causing the rotating plate 16 and rotating plate 2 17 to rotate within the ventilation opening 14, so that the rotating plate 16 and rotating plate 2 17 fit together. Then, the fan 13 is turned on to allow cold air from outside the tunnel kiln to enter the tunnel kiln. Then, the tunnel kiln door 25 is opened to allow the heat inside the tunnel kiln to be discharged. At this time, the air cooler 22 is turned on to allow cold air to enter the tunnel kiln body 1. With the help of the fan 13, the cooling speed is accelerated. The staff can enter the tunnel kiln body 1 to take out the products without waiting for a long time, which increases the work efficiency.

[0034] Working Principle: Before the cooling process begins, the finished products in the tunnel kiln have reached the tail end. Then, motor 2 is turned on, causing its output to drive pulley 3 to rotate within the tunnel kiln body 1. This, in turn, drives the high-temperature belt 4 to rotate within the tunnel kiln body 1. One end of the high-temperature belt 4 drives pulley 5 to rotate within the tunnel kiln body 1. Simultaneously, sliders 6 and 7, fixed to the high-temperature belt 4, move towards the center of the belt. This also causes isolation doors 8, 9, 10, and 11 to rotate within the tunnel kiln body 1. Once they reach a horizontally aligned position, motor 2 is turned off, isolating the middle and tail ends of the tunnel kiln. This prevents cold air from entering the middle of the tunnel kiln during the cooling process at the tail end, thus preventing cooling at the tail end and affecting the quality of the products in the middle. Then, the electric telescopic rod 20 is activated, causing its output to drive the guide column. Guide post 18 and guide post 29 move away from the electric telescopic rod 20, so that guide post 18 and guide post 29 are in contact with each other. At this time, rotating plate 16 and rotating plate 27 rotate inside the fixed post 15, so that rotating plate 16 and rotating plate 27 are in contact with each other. Then, the electric telescopic rod 20 is closed and the fan 13 is turned on. Then, the locking post 28 is rotated so that one end of the locking post 28 is away from the fixed block 1 26. Then, the tunnel kiln door 25 slides on one side of the tunnel kiln body 1, so that the tunnel kiln door 25 is in the open state. At this time, the cold air outside the tunnel kiln enters the tunnel kiln. Then, the tunnel kiln door 25 is opened to exhaust the heat inside the tunnel kiln. At this time, the cold air fan 22 is turned on, so that the cold air enters the tunnel kiln body 1 through the air collection box 23 and the four sets of air guide pipes 24. With the action of the fan 13, the cooling speed is accelerated, the cooling time is shortened, and the work efficiency is increased. After cooling is completed, the staff can enter through the tunnel kiln door 25 to take out the cooled products.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
