Description

Technical Field

[0001] This application relates to the field of cement production technology, and more specifically, to a preheating device for producing cement using solid waste. Background Technology

[0002] The utilization of solid waste resources in the cement industry is mainly reflected in the utilization of raw materials. Industrial waste residues (such as fly ash and blast furnace slag) are used as cement raw materials or admixtures to replace natural resources. This not only avoids the pollution of the environment by solid waste, but also saves cement production costs.

[0003] In the cement production process, cement raw materials need to be preheated. However, cement raw materials tend to agglomerate, and existing preheating devices cannot fully disperse them, thus affecting the preheating effect. Utility Model Content

[0004] The purpose of this application is to provide a preheating device for cement production using solid waste, which improves the dispersion of cement raw materials and ensures that the cement raw materials are fully preheated.

[0005] This application provides a preheating device for cement production using solid waste, employing the following technical solution:

[0006] A preheating device for producing cement using solid waste includes a preheating box, a feeding hopper at the upper end of the preheating box, a hot air pipe and a discharge pipe at the side of the preheating box, and the discharge pipe being located below the hot air pipe.

[0007] The preheating chamber is equipped with multiple baffles and multiple sets of dispersing mechanisms. The baffles are arranged at an angle, and the baffles and the dispersing mechanisms are distributed at intervals from top to bottom. The dispersing mechanism includes a rotating rod and multiple blades. The rotating rod is rotatably disposed inside the preheating chamber, and the blades are disposed on the rotating rod.

[0008] Preferably, a plurality of drive motors are provided on the outer wall of the preheating box, and the drive motors drive the rotating rod to rotate.

[0009] Preferably, a flow guide block is provided at the lower end of the preheating box.

[0010] Preferably, the preheating box is provided with an exhaust pipe at its upper end.

[0011] Preferably, the exhaust pipe is connected to an exhaust fan, which is installed on the outer wall of the preheating box.

[0012] Preferably, the lower end of the preheating box is provided with multiple support rods.

[0013] Preferably, multiple vibration motors are installed on the outer wall of the preheating box.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] This application incorporates baffles and a dispersion mechanism inside the preheating chamber. After cement raw materials are added to the preheating chamber, they impact the blades under their own weight. As the cement raw materials are dispersed, they exert a force on the blades, causing the blades to rotate and the cement raw materials to be thrown against the inner wall of the preheating chamber. Subsequently, the cement raw materials fall onto the baffles and slide down them, then impact the blades below again. This process is repeated, resulting in multi-stage dispersion and increasing the degree of dispersion of the cement raw materials. Due to the obstruction effect of the baffles, the passage time of hot air inside the preheating chamber is prolonged, thereby ensuring sufficient contact between the cement raw materials and the hot air and improving the preheating effect.

[0027] Example

[0028] like Figure 1 and Figure 2As shown in the embodiment of this application, the preheating device for producing cement using solid waste includes a preheating box 1. A feed hopper 2 is provided at the upper end of the preheating box 1. A hot air pipe 3 and a discharge pipe 4 are provided on the side of the preheating box 1. The discharge pipe 4 is located below the hot air pipe 3. Multiple baffles 5 and multiple sets of dispersing mechanisms 6 are provided inside the preheating box 1. The baffles 5 are arranged at an angle. The baffles 5 and the dispersing mechanisms 6 are distributed alternately from top to bottom. The dispersing mechanism 6 includes a rotating rod 7 and multiple blades 8. The rotating rod 7 is rotatably disposed inside the preheating box 1, and the blades 8 are disposed on the rotating rod 7.

[0029] In use, hot air is blown into the preheating box 1 through the hot air pipe 3, and cement raw materials are fed into the preheating box 1 through the feed hopper 2. Under the action of the cement raw materials' own gravity, the cement raw materials hit the blades 8. While being dispersed, the cement raw materials exert a force on the blades 8. The blades 8 drive the rotating rod 7 to rotate, and the cement raw materials are thrown against the inner wall of the preheating box 1. Then the cement raw materials fall on the baffle 5 and slide down the baffle 5, and then hit the blades 8 below again. This process is repeated, and through multiple stages of dispersion, the degree of dispersion of the cement raw materials is improved. Due to the obstruction effect of the baffle 5, the passage time of the hot air inside the preheating box 1 is prolonged, so that the cement raw materials and the hot air can fully contact each other, thereby improving the preheating effect.

[0030] In this embodiment, multiple drive motors 9 are provided on the outer wall of the preheating box 1. The drive motors 9 drive the rotating rod 7 to rotate. When in use, the rotating rod 7 can be rotated in a specific direction under the drive of the motor to ensure the effect of use.

[0031] In this embodiment, a guide block 10 is provided at the lower end of the preheating box 1. The guide block 10 plays a guiding role, which facilitates the preheated cement raw material to enter the discharge pipe 4.

[0032] In this embodiment, an exhaust pipe 11 is provided at the upper end of the preheating box 1. The exhaust pipe 11 is used to discharge the gas after heat exchange inside the preheating box 1.

[0033] In this embodiment, the exhaust pipe 11 is connected to the exhaust fan 12. When in use, the exhaust fan 12 generates a negative pressure inside the preheating box 1, which facilitates the extraction of the gas after heat exchange inside the preheating box 1 and the centralized treatment of the gas, thereby preventing dust from overflowing and improving the working environment. The exhaust fan 12 is installed on the outer wall of the preheating box 1.

[0034] In this embodiment, a plurality of support rods 13 are provided at the lower end of the preheating box 1, and the support rods 13 are used to support the preheating box 1.

[0035] In this embodiment, a plurality of vibration motors 14 are provided on the outer wall of the preheating box 1. When in use, the vibration motors 14 work to make the preheating box 1 vibrate, thereby improving the smoothness of cement raw material feeding.

[0036] The above are merely preferred embodiments of this application and are 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.
