Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a raw material humidifying tower of a cement production line. Background Art

[0002] Raw meal refers to the original material used to prepare clinker (i.e. cement clinker) in the cement production process, which is usually a mixture of limestone, clay, iron ore, etc. After these raw materials are crushed, mixed and ground, they form a material called raw meal for the subsequent sintering process. Cement production line refers to the industrial production system used to produce cement. It is a complex engineering system consisting of multiple processes and equipment, which converts raw materials into finished cement products through a series of steps. Cement production line usually includes process steps such as raw material crushing, raw material pretreatment, raw material sintering, clinker grinding, and cement grinding. In cement production line, in order to control the humidity of raw materials and ensure that the raw materials have a suitable moisture content when entering the preheater and rotary kiln, humidification towers are usually used to moisten the raw materials. Humidification tower is a device used to adjust the humidity of materials. It is usually set in the raw material preparation stage of cement production line. There is a water spraying device inside the humidification tower, which can spray a certain amount of water into the material to increase the humidity of the material. The main purpose of the humidification tower is to ensure that the raw material has appropriate humidity before entering the next process (such as preheater, rotary kiln, etc.) to avoid excessive dust and caking during the calcination process. At the same time, by changing the humidity of the raw material, the heat balance and reaction rate in the sintering process are adjusted, thereby optimizing the sintering process and improving the quality and output of cement clinker.

[0003] When the raw meal is moistened by a humidifying tower, water mist is usually sprayed on the raw meal through a spraying device to achieve humidification. Since the water mist becomes moist after contacting the raw meal, and in the prior art, the humidified raw meal cannot be stirred well, so that the moisture distribution in the raw meal may be uneven, and then some areas may be too moist, while other areas are too dry, which will cause uneven reaction of the raw meal in subsequent processes, thereby affecting the production quality of cement. Therefore, in order to solve the above problems, a raw meal humidifying tower for a cement production line is proposed. Utility Model Content

[0023] A raw material humidification tower for a cement production line comprises a tower body, the tower body comprising a tower body 1, a water pump 11 is fixedly installed on the surface of the tower body 1, a conveying pipe 12 is fixedly connected to the inner side of the tower body 1, a nozzle 13 is fixedly connected to the bottom end of the conveying pipe 12, a vent 14 is provided at the top of the tower body 1, a fan 15 is installed on the inner side of the tower body 1, a conveying box 16 is fixedly connected to the surface of the tower body 1, a first spiral conveying rod 17 is movably connected to the inner side of the conveying box 16, a first motor 18 is fixedly installed on the surface of the conveying box 16, a feed port 19 is arranged at the top of the conveying box 16, and a The discharge port 110 drives the first screw conveying rod 17 to rotate through the operation of the first motor 18, so that the first screw conveying rod 17 can convey the raw material to the inner side of the tower body 1. The water pump 11 can be used to draw water from an external source into the conveying pipe 12 and spray it out through the nozzle 13. When the water mist contacts the raw material, the water will be adsorbed onto the surface of the raw material, so that the raw material can be moistened. The fan 15 can generate airflow to purge the raw material, so that the raw material is moistened more evenly. The moist raw material can be discharged through the discharge port 110 and enter the next process.

[0024] A stirring mechanism is arranged on the inner side of the tower body 1, and the stirring mechanism includes a first rotating rod 22, which is movably connected to the inner side of the tower body 1, and a first conical tooth 23 is fixedly connected to the surface of the first rotating rod 22, and a second motor 24 is fixedly installed on the surface of the tower body 1, and one end of the first rotating rod 22 away from the first conical tooth 23 is fixedly connected to the output end of the second motor 24, and a second rotating rod 25 is movably connected to the inner side of the tower body 1, and a second conical tooth 26 is fixedly connected to the top of the second rotating rod 25, and a stirring rod 27 is fixedly connected to the surface of the second rotating rod 25, and a scraper 28 is fixedly connected to the surface of the stirring rod 27. By rotating the second rotating rod 25, the stirring rod 27 can rotate to stir the raw material, thereby achieving mixing of the raw material, making the moisture in the raw material evenly distributed, improving the quality of humidification, and facilitating subsequent processing of cement.

[0025] Furthermore, the stirring mechanism also includes a fixed rod 2, which is fixedly connected to the inner wall of the tower body 1, and a fixed block 21 is fixedly connected to the upper surface of the fixed rod 2.

Through the setting of the second spiral conveying rod 38, the second rotating rod 25 can rotate accordingly during its rotation, thereby facilitating the smooth discharge of raw material through the discharging port 110, avoiding blockage of the discharging port 110, improving the discharging efficiency, and facilitating cement production.

[0028] Furthermore, one end of the third rotating rod 31 away from the cam 32 is fixedly connected to the output end of the third motor 33, and the second spiral conveying rod 38 moves on the inner side of the discharge port 110. By driving the cam 32 to rotate through the third rotating rod 31, the cam 32 can squeeze the movable rod 35, and then the movable rod 35 can drive the striking block 36 to move.

[0029] Furthermore, one end of the spring 37 is fixedly connected to the connecting block 34, and the other end of the spring 37 is fixedly connected to the movable rod 35. Through the setting of the spring 37, the movable rod 35 can be reset, thereby facilitating the reset of the striking block 36.

[0030] Working principle: When in use, the second motor 24 is electrically connected to an external power source, and the staff starts the second motor 24 by pressing a switch. The operation of the second motor 24 drives the first rotating rod 22 to rotate, and the first conical teeth 23 rotate under the action of the first rotating rod 22, and then the second conical teeth 26 rotate under the action of the first conical teeth 23 and drive the second rotating rod 25 to rotate, and the stirring rod 27 and the scraper 28 rotate accordingly under the action of the second rotating rod 25. The stirring rod 27 can stir the raw material by rotating, and the scraper 28 can scrape the inner wall of the tower body 1 by rotating, thereby avoiding the adhesion of the raw material;

[0031] The second spiral conveying rod 38 will rotate accordingly during the rotation of the second rotating rod 25, so as to convey the moist raw material, so that the raw material can be stably discharged through the discharge port 110. The cam 32 is electrically connected to an external power supply. The staff starts the cam 32 by pressing the switch. The operation of the cam 32 drives the third rotating rod 31 to rotate. The cam 32 will rotate accordingly under the action of the third rotating rod 31. When the cam 32 squeezes the movable rod 35 during the rotation, the movable rod 35 will move on the inner side of the connecting block 34 and drive the striking block 36 to move, so that the striking block 36 strikes the discharge port 110. At this time, the spring 37 is in a contracted state. When the cam 32 cancels the squeezing of the movable rod 35 during the rotation, the spring 37 can drive the movable rod 35 and the striking block 36 to reset, and then through the cooperation of the cam 32 and the spring 37, the striking block 36 can reciprocate, thereby continuously striking the discharge port 110, so that the raw material falls better.
