[0002] The material classification and optimization device inside the cement mill is a key piece of equipment used in the cement production process to improve grinding efficiency and optimize product quality. It ensures that materials of different particle sizes are properly processed by precisely classifying the particle size of the materials inside the mill.

[0003] For example, Chinese patent CN220215208U discloses a classifier for high-moisture materials used in cement mills, including a classifier body, an auxiliary feeding inlet at the upper end of the classifier body, a support base fixedly installed at the upper end of the classifier body, a feeding mechanism inside the support base, and a screening mechanism fixedly installed on the upper outer surface of the support base.

[0004] Although the aforementioned patent solves the problem of blockage caused by material residue in the feed pipe by driving the dispersing unit and the crushing unit, the moisture in the material is prone to condensation in the low-temperature area inside the classifier, which combines with the fine powder to form a paste, causing blockage of the classifier's air duct and screen, and affecting the normal use of the classifier. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that moisture in materials easily condenses in the low-temperature area inside the air classifier, combining with fine powder to form a paste, which blocks the air duct and screen of the air classifier and affects the normal operation of the air classifier. Therefore, this invention proposes a material classification optimization device for cement mills.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a material classification and optimization device for a cement mill, comprising a classifier body, a feed pipe fixedly connected to the top of the classifier body, a drying mechanism provided on one side of the feed pipe, the drying mechanism comprising a hopper, a fan blade, and a heating frame, a heating plate fixedly connected to the inner wall of the hopper, the bottom of the hopper fixedly connected to the outer shell of a screw feeder, an auger assembly rotatably connected inside the outer shell of the screw feeder, the fan blade being penetrated by the auger assembly, the inner ring surface of the fan blade being fixedly connected to the auger assembly, the inner wall of the heating frame being fixedly connected to the outer shell of the screw feeder, a reinforcing plate fixedly connected to the bottom of the outer shell of the screw feeder, and one side of the reinforcing plate being fixedly connected to the classifier body.

[0007] Preferably, a sealing plate is fixedly connected to the top of the hopper, a motor is fixedly connected to the top of the sealing plate, and a stirring rod is fixedly connected to one end of the motor's output shaft, with the stirring rod rotatably connected to the hopper.

[0008] Preferably, a filter plate is snapped onto the top of the screw feeder housing, and a temperature and humidity sensor is installed on one side of the filter plate. The top of the temperature and humidity sensor is fixedly connected to the screw feeder housing.

[0009] Preferably, a vacuum cleaner is fixedly connected to the top of the screw feeder housing, and the vacuum cleaner is fixedly connected to a dust collection hood through a pipe, with the bottom of the dust collection hood fixedly connected to the screw feeder housing.

[0010] Preferably, the outer wall of the screw feeder housing is fixedly connected to three connecting pipes, and the three connecting pipes are fixedly connected to each other through connecting pipes.

[0011] Preferably, an anti-clogging nozzle is fixedly connected to the outer ring surface of the connecting pipe, and the end of the anti-clogging nozzle penetrates the side wall of the screw feeder housing.

[0012] Preferably, a screen is slidably connected inside the feed pipe, and one side of the screen is engaged with the side wall of the feed pipe.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the heating plate is fixedly connected to the inner wall of the hopper, and the heating frame is fixedly connected to the outer shell of the screw conveyor. The stirring rod drives the material to rotate and contact the heating plate. After the material is preheated, it enters the outer shell of the screw conveyor and is conveyed inside the screw conveyor. The temperature inside the outer shell of the screw conveyor can be adjusted by the heating frame. The fan blades accelerate the air flow inside the outer shell of the screw conveyor, thereby drying the material while it is being conveyed, reducing the moisture content inside the material, and preventing the moisture in the material from condensing in the low-temperature area inside the main body of the classifier, which would cause blockage and ensure the normal use of the main body of the classifier.

[0015] 2. In this utility model, connecting pipe one and connecting pipe two are fixedly connected, and the vacuum cleaner and the dust collection hood are fixedly connected. Connecting pipe two sends compressed air into connecting pipe one and discharges it through the anti-clogging nozzle to blow the inside of the screw feeder housing. The vacuum cleaner and dust collection hood adsorb and collect dust above the feed pipe, reducing the residue of material inside the screw feeder housing, facilitating subsequent cleaning of the screw feeder housing and recycling of materials, and reducing material waste.

The fan blades 15 are penetrated by the auger assembly 16, and the inner ring surface of the fan blades 15 is fixedly connected to the auger assembly 16. The inner wall of the heating frame 17 is fixedly connected to the screw conveyor. The screw feeder housing 4 is fixedly connected. A reinforcing plate 18 is fixedly connected to the bottom of the screw feeder housing 4. One side of the reinforcing plate 18 is fixedly connected to the powder classifier body 2. A sealing plate is fixedly connected to the top of the hopper 3. A motor 10 is fixedly connected to the top of the sealing plate. A stirring rod 13 is fixedly connected to one end of the output shaft of the motor 10. The stirring rod 13 is rotatably connected to the hopper 3. A filter plate 19 is snapped into the top of the screw feeder housing 4. A temperature and humidity sensor 11 is set on one side of the filter plate 19. The top of the temperature and humidity sensor 11 is fixedly connected to the screw feeder housing 4.

[0024] The heating plate 14 can be used to adjust the temperature inside the hopper 3 to preheat the material. The motor 10 drives the stirring rod 13 to rotate, so that the stirring rod 13 stirs the material and makes the material at different positions contact the heating plate 14, which can improve the uniformity of the material contact with the heating plate 14. The rotation of the auger assembly 16 can realize the conveying of the material. The rotation of the fan blade 15 can accelerate the air flow inside the screw feeder shell 4. The heating frame 17 can adjust the temperature inside the screw feeder shell 4, thereby assisting in the drying of the material inside the screw feeder shell 4 and reducing the moisture content inside the material. The filter plate 19 can discharge hot air, thereby reducing the condensation of water vapor inside the screw feeder shell 4.

[0025] Example 2: Figures 1-3 As shown, a vacuum cleaner 5 is fixedly connected to the top of the screw feeder housing 4. The vacuum cleaner 5 is fixedly connected to a dust collection hood 6 through a pipe. The bottom of the dust collection hood 6 is fixedly connected to the screw feeder housing 4. Three connecting pipes 1 8 are fixedly connected to the outer wall of the screw feeder housing 4. The three connecting pipes 1 8 are fixedly connected to each other through connecting pipe 2 9. An anti-clogging nozzle 12 is fixedly connected to the outer ring surface of the connecting pipe 1 8. The end of the anti-clogging nozzle 12 penetrates the side wall of the screw feeder housing 4. A screen 7 is slidably connected inside the feed pipe 1. One side of the screen 7 is engaged with the side wall of the feed pipe 1.

[0026] The screw feeder housing 4 can be used to support the bottom of the vacuum cleaner 5. The vacuum cleaner 5 and the dust hood 6 can be connected through the pipe.

The screen 7 can filter the material discharged into the feed pipe 1.

[0027] The operating method and working principle of this device are as follows: First, the material to be processed is fed into the hopper 3 through the feed inlet on one side of the hopper 3. The stirring rod 13 is driven by the motor 10 to rotate, and the stirring rod 13 stirs the material, causing the material to come into contact with the heating plate 14 and be preheated. The drive structure on one side of the screw conveyor shell 4 drives the auger assembly 16 to rotate, conveying the material. During the conveying process, the heating frame 17 heats the screw conveyor shell 4, regulating the internal temperature of the screw conveyor shell 4. The fan blades 15 rotate with the auger assembly 16, accelerating the airflow inside the screw conveyor shell 4 during the conveying process. The material is dried in time. When the material moves above the feed pipe 1, the humidity of the material can be detected by the temperature and humidity sensor 11. The screen 7 is removed and the material can enter the main body 2 of the classifier through the feed pipe 1 for grading. When it is necessary to process the residual material inside the screw feeder shell 4, the external air compressor is connected to the connecting pipe 2 9. The anti-clogging nozzle 12 is a compressed air nozzle with anti-clogging effect, which can discharge air from multiple angles to blow the material. The material can be adsorbed by the vacuum cleaner 5 and the dust hood 6. The remaining material can fall into the feed pipe 1.
