Description

Technical Field

[0001] The utility model relates to the technical field of sludge burning, in particular to a burning box for baking sludge for environmental protection and making sludge bricks. Background Art

[0002] The sludge brick firing box is a device used in the brick firing process. When making bricks, raw materials containing sludge (such as soil, fly ash, etc.) are usually used. The brick firing box is used to make these raw materials into wet bricks and then fire them. It is usually a closed box or indoor space that can control the burning process of the bricks at high temperatures so that they will eventually form solid bricks.

[0003] The current design of sludge brick firing boxes allows them to be stacked and pushed into the kiln for centralized firing. Although this stacking improves production efficiency, it also brings some problems. Since the fire-exposed area of ​​the upper and lower layers of bricks is greatly reduced, the permeability effect is significantly reduced, which may cause the bricks to be heated unevenly during the firing process, affecting the final quality and strength of the bricks. In addition, the current sludge brick firing boxes are usually placed directly when stacked, with poor stability and the risk of tilting or collapse, especially when fired at high temperatures for a long time. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an environmentally friendly sludge baking box for sludge brick making, which has high upper and lower stacking stability, large fire-receiving area and good uniform burning effect.

[0005] In order to solve the above-mentioned technical problems, the technical solution proposed in the utility model is: a firing box for environmentally friendly sludge roasting and sludge brick making, comprising a box body, a square frame is provided on the top of the box body, the four corners of the square frame are connected to the four corners of the box body through support rods, the upper edge of the square frame and the inner side of the lower end of the box body are chamfered to match each other, a plurality of air holes 1 and air grooves are provided on the side walls of the box body, a plurality of through grooves are provided on the bottom plate of the box body, a plurality of air holes 2 are provided on the bottom plate of the box body, and limit plates are connected to the four corners of the lower end of the box body.

[0006] Furthermore, the ventilation grooves are arranged obliquely, and the inclination directions of the ventilation grooves on each side are consistent.

[0007] Based on the above characteristics, the air permeable grooves arranged obliquely can increase the air permeable area and improve the firing efficiency. The air permeable grooves with the same inclination direction can also increase the stability of the box.

[0008] Furthermore, the height of the lower edge of the box body is lower than the height of the lower wall of the box body bottom plate.

[0009] Based on the above characteristics, direct contact between the lower wall of the box and the ground can be avoided, thereby improving the safety and ventilation of the bricks.

[0010] Furthermore, the limiting plate is an L-shaped plate, and the lower bottom surface of the limiting plate is lower than the lower bottom surface of the box body.

[0011] Based on the above features, the limit plate can effectively limit the joints of the boxes stacked up and down, thereby ensuring the stability of the boxes, and can also support the bottom box to ensure ventilation under the box.

[0012] Furthermore, the inner lower end of the limiting plate is a curved surface.

[0013] Based on the above features, it is convenient to stack the boxes up and down, and can effectively avoid collision and scratches between the limit plate and the square frame, which is safe and stable.

[0014] Compared with the prior art, the utility model has the following advantages: the square frame and the lower end of the box body are provided with chamfers that cooperate with each other, which can increase the stability of the boxes when they are stacked up and down; the setting of the limit plate can limit the boxes at the stacking position of the boxes, effectively avoiding the offset between the two boxes placed up and down, and further increasing the stability and safety during the firing process; the setting of the air hole 1, the air groove, the through groove and the air hole 2 can ensure that all sides of the box body can be exposed to fire, which is conducive to achieving uniform heating and stable firing; and the setting of the square frame and the support rod can greatly improve the heating efficiency inside the box body and achieve a good firing effect.
