Description
Technical Field
[0001] This utility model relates to the field of kiln car technology, specifically to a tunnel kiln car. Background Technology
[0002] Kiln cars are the equipment that carries brick or tile blanks for firing inside a tunnel kiln. They are also the most important auxiliary equipment of a tunnel kiln. The design and manufacture of kiln cars depend not only on the structure of the kiln itself and the materials used, but also on the quality and output of the fired products, the pressure balance inside the kiln, and the lifespan of the kiln cars themselves. Therefore, paying attention to the structural design and manufacturing of kiln cars is of utmost importance to ensuring the normal operation of the kiln.
[0003] In existing technologies, the support platform of a kiln car is usually constructed from multiple smaller kiln car bricks. The brick joints on the support platform are numerous, and as the kiln car is used, quartz sand can easily enter the brick joints of the support platform, causing the gaps to widen. This results in the kiln car becoming larger, and when the kiln car enters the kiln for firing, it may scrape against the kiln wall. There is a risk that the kiln car bricks may get stuck in the gaps between the kiln car and the kiln wall, leading to the kiln car collapsing and causing equipment accidents. At the same time, the kiln car bricks in tunnel kilns require frequent maintenance, resulting in a large consumption of kiln car bricks. Summary of the Invention
[0004] This invention addresses the problem in existing technologies where quartz sand enters the brick joints of the kiln car's support platform, causing the kiln car to easily scrape against the kiln wall when entering the kiln. The invention provides a tunnel kiln car whose support platform is constructed of multiple layers of brick masonry. The bricks of adjacent masonry layers are staggered, and the brick size is increased to reduce the number of brick joints. This effectively reduces the amount of quartz sand entering the kiln car's support platform, preventing scraping against the kiln wall when the kiln car enters the kiln, and thus preventing the kiln car bricks from getting stuck in the gap between the kiln car and the kiln wall.
[0005] To achieve the above objectives, the technical solution of this utility model is: a tunnel kiln car, including a kiln car frame, a track wheel assembly at the bottom of the kiln car frame, and a first layer of brick masonry, a second layer of brick masonry, a third layer of brick masonry, a fourth layer of brick masonry, a fifth layer of brick masonry, and a sixth layer of brick masonry arranged sequentially from bottom to top on the top of the kiln car frame. The track wheel assembly enables the kiln car to move within the tunnel kiln, and the first, second, third, fourth, fifth, and sixth layers of brick masonry constitute the carrying platform of the kiln car.
[0006] The width of the sixth layer of brickwork is less than that of the fifth layer of brickwork, while the widths of the third and fourth layers of brickwork are greater than those of the second and fifth layers. This is to prevent quartz sand from entering the brick joints of the sixth and fifth layers of brickwork, which would increase the width of the sixth and fifth layers of brickwork and cause them to rub against the tunnel kiln wall. At the same time, it ensures that the sides of the third and fourth layers of brickwork match the kiln troughs on the tunnel kiln wall.
[0007] The second and third brick masonry layers are staggered, as are the fourth and fifth brick masonry layers. One end of the third and fourth brick masonry layers forms a protrusion, and the gap between one end of the second and fifth brick masonry layers forms a depression. Through the action of the protrusions and depressions, the kiln cars can be spliced together, reducing the heat entering under the kiln cars and preventing the heat from affecting the kiln car frame.
[0008] Furthermore, the number of track wheel assemblies is two. Each track wheel assembly includes a fixed shaft and track wheels. The fixed shaft is fixedly connected to the kiln car frame, and the track wheels are rotatably mounted on both ends of the fixed shaft. The kiln car frame serves to install the brickwork and track wheel assemblies, and the track wheels prevent the kiln car from moving in the tunnel kiln.
[0009] Furthermore, the first layer of brickwork includes a first layer of brick body one, a first layer of brick body two, and a first layer of brick body three. Two sets of the first layer of brick body one are arranged vertically side by side on the top of the kiln car frame. The first layer of brick body two and the first layer of brick body three are arranged vertically side by side on the outer side of the two sets of the first layer of brick body one, respectively. The first layer of brick body two is arranged vertically side by side on the outer side of the first layer of brick body three. Two sets of the first layer of brick body one are arranged side by side on the outer side of each of the two sets of the first layer of brick body two. The first layer of brickwork is formed by the mutual arrangement and combination of the first layer of brick body one, the first layer of brick body two, and the first layer of brick body three.
[0010] Furthermore, the second layer of brickwork includes a second layer of brick body one, a second layer of brick body two, a second layer of brick body three, and a second layer of brick body four. Multiple second layer of brick body one are spaced apart on the top of the first layer of brickwork. A second layer of brick body two is arranged between two adjacent second layer of brick body one arranged horizontally side by side. Multiple second layer of brick body three are arranged between two groups of second layer of brick body one arranged horizontally side by side. A second layer of brick body four is arranged between two adjacent second layer of brick body three. An inclined part one is provided at the end of the second layer of brick body one and the end of the second layer of brick body two. The second layer of brickwork is formed by the mutual arrangement and combination of the second layer of brick body one, the second layer of brick body two, the second layer of brick body three, and the second layer of brick body four.
[0011] Furthermore, the third layer of brickwork includes a third layer of brick body one, a third layer of brick body two, a third layer of brick body three, and a third layer of brick body four. Three sets of the third layer of brick body three are vertically arranged side-by-side on the top of the second layer of brickwork. The third layer of brick body two and the third layer of brick body four are vertically arranged side-by-side on the outer sides of two sets of the third layer of brick body three, respectively. The third layer of brick body two is also vertically arranged side-by-side on the outer side of the third layer of brick body four. The third layer of brick body one is arranged side-by-side on the outer sides of both sets of the third layer of brick body two. An inclined portion two is provided at the bottom of the third layer of brick body one, the third layer of brick body two, the third layer of brick body three, and the third layer of brick body four at one end of the third layer of brickwork. The third layer of brickwork is formed by the mutual arrangement and combination of the third layer of brick body one, the third layer of brick body two, the third layer of brick body three, and the third layer of brick body four. The inclined portion two facilitates the matching of the protrusion of one kiln car with the concave part of the other kiln car between two adjacent kiln cars.
[0012] Furthermore, the fourth layer of brickwork includes a fourth layer of brick body one, a fourth layer of brick body two, and a fourth layer of brick body three. Two sets of fourth layer of brick body one are vertically arranged side-by-side on the top of the third layer of brickwork. A fourth layer of brick body two is arranged side-by-side between the two sets of fourth layer of brick body one. Fourth layer of brick body three is vertically arranged side-by-side on the outer sides of both sets of fourth layer of brick body one. An inclined portion three is provided at the top edge of the fourth layer of brick body three. An inclined portion four is provided at the ends of the fourth layer of brick body one, fourth layer of brick body two, and fourth layer of brick body three at one end of the fourth layer of brickwork. The fourth layer of brickwork is formed by the mutual arrangement and combination of the fourth layer of brick body one, fourth layer of brick body two, and fourth layer of brick body three. The inclined portion three facilitates the interaction between the sides of the third and fourth layers of brickwork and the kiln trough on the tunnel kiln wall, thereby reducing the heat entering below the kiln car. The inclined portion four facilitates the interaction between the protrusion of one kiln car and the recess of the other kiln car in two adjacent kiln cars.
[0013] Furthermore, the fifth layer of brickwork includes multiple fifth-layer bricks arranged side by side on top of the fourth layer of brickwork. An inclined portion is provided at the bottom edge of the fifth-layer bricks at one end of the fifth-layer brickwork. The fifth layer of brickwork is formed by arranging and combining multiple fifth-layer bricks together.
[0014] Furthermore, the sixth layer of brickwork includes multiple sixth layer bricks arranged side by side on top of the fifth layer of brickwork. Among them, multiple sixth layer bricks are arranged side by side on the outer side of a group of sixth layer bricks arranged horizontally. The sixth layer of brickwork is formed by the mutual arrangement and combination of the sixth layer bricks and the sixth layer bricks.
[0015] The beneficial effects of this utility model through the above technical solution are as follows:
[0016] This utility model has a reasonable structure and good performance. The kiln car's support platform is formed by six layers of brick masonry: the first, second, third, fourth, fifth, and sixth layers. The bricks of adjacent layers are staggered, and by increasing the size of the bricks to reduce the number of brick joints, the amount of quartz sand entering the kiln car's support platform can be effectively reduced. This prevents the kiln car from becoming too large and avoids it scraping against the kiln wall when entering the kiln, thus preventing the bricks from getting stuck in the gap between the kiln car and the kiln wall, and preventing the kiln car from collapsing and causing equipment accidents. At the same time, the tunnel kiln's kiln car bricks do not require frequent maintenance, reducing the consumption of kiln car bricks.
[0017] This invention increases the width of the fourth, fifth, and sixth brick layers sequentially, allowing the sides of the third and fourth brick layers to fit into the kiln troughs on the tunnel kiln wall, thus creating a seal. This reduces heat entering under the kiln car, preventing excessive heat from affecting and damaging the kiln car frame. Simultaneously, it prevents quartz sand from entering the brick joints of the sixth and fifth brick layers, thus avoiding the increased width of the sixth and fifth brick layers and preventing them from rubbing against the tunnel kiln wall.
[0018] This utility model uses staggered arrangement of the second and third layers of brick masonry, and staggered arrangement of the fourth and fifth layers of brick masonry, so that adjacent kiln cars can be spliced together through protrusions and depressions, thereby reducing the heat entering under the kiln car and avoiding the heat affecting the kiln car frame.
