Description

Technical Field

[0001] This utility model relates to the field of cement coal mill technology, specifically a cement coal mill device with a high-efficiency drying function. Background Technology

[0002] In the cement production process, the cement coal mill is a key piece of equipment for grinding coal into coal powder, and the degree of dryness of the coal powder has a significant impact on the quality and efficiency of cement production.

[0003] Existing cement coal mill equipment has many drawbacks. Particularly in the drying stage, water vapor generated during drying accumulates in large quantities on the ceiling of the drying chamber. Over time, these water droplets accumulate, and once they reach a certain level, they easily drip back down. These dripping water droplets, once they land on the cement being dried, severely interfere with the drying process. On the one hand, they increase the localized moisture content of the cement, leading to uneven moisture content after drying and affecting the cement's quality stability. On the other hand, this undoubtedly prolongs the overall drying time, reduces production efficiency, and increases energy consumption and production costs.

[0004] To address these issues, we designed a cement coal mill with a high-efficiency drying function. Utility Model Content

[0005] The purpose of this invention is to provide a cement coal mill device with a high-efficiency drying function to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a cement coal mill device with high-efficiency drying function, including a coal mill box. The inside of the coal mill box is arranged from top to bottom as a grinding chamber and a drying chamber. A guide plate is fixedly connected to the bottom of the grinding chamber. The guide plate is inclined and its inclined end leads to the drying chamber. A condensing plate is arranged at the top of the drying chamber. The condensing plate is inclined in the opposite direction to the inclination of the guide plate. A hot air blower is fixedly connected to the inner wall of the drying chamber on the side near the inclined top of the condensing plate. A condensing pipe is fixedly connected to the bottom end of the condensing plate. A water collection tank is fixedly connected to the inner wall of the drying chamber on the side away from the hot air blower.

[0007] Furthermore, the top opening of the water collection tank is opposite to the inclined bottom end of the condenser tube, and a water outlet pipe is fixedly inserted into the bottom end of the outer wall of the water collection tank.

[0008] Furthermore, the guide plate is inclined with the left side higher than the right side, and the condenser plate is inclined with the right side higher than the left side. The right side of the guide plate and the left side of the condenser plate are fixedly connected.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 2 and Figure 3 This utility model provides a technical solution: a cement coal mill device with high-efficiency drying function, including a coal mill box 1. The inside of the coal mill box 1 is arranged from top to bottom as a grinding chamber 2 and a drying chamber 3. A guide plate 4 is fixedly connected to the bottom of the grinding chamber 2. The guide plate 4 is inclined and its inclined end leads into the drying chamber 3. A condensing plate 5 is arranged at the top of the drying chamber 3. The condensing plate 5 is inclined and its inclination direction is opposite to that of the guide plate 4. A hot air blower 6 is fixedly connected to the inner wall of the drying chamber 3 near the inclined top of the condensing plate 5. A condensing pipe 7 is fixedly connected to the bottom of the condensing plate 5. A water collection tank 8 is fixedly connected to the inner wall of the drying chamber 3 away from the hot air blower 6. The top opening of the water collection tank 8 is opposite to the inclined bottom of the condensing pipe 7. A water outlet pipe 9 is fixedly inserted into the bottom of the outer wall of the water collection tank 8. The guide plate 4 is inclined with the left side higher than the right side, and the condensing plate 5 is inclined with the right side higher than the left side. The right side of the guide plate 4 and the left side of the condensing plate 5 are fixedly connected.

[0023] In practice, the ground material enters the drying chamber 3 through the guide plate 4. The hot air blower 6 inside the drying chamber 3 operates, blowing hot air into the chamber to dry the material. During the drying process, the moisture in the material turns into water vapor and rises. When excessive water vapor is generated, the condenser 7 begins to function, cooling the excess steam and causing more steam to condense into water droplets. These droplets flow downwards along the inclined direction of the condenser plate 5 and drip into the water collection tank 8. The water collection tank 8 collects the dripping condensate, preventing it from dripping back onto the surface of the material being dried, thus ensuring the drying effect and speed.

[0024] See Figure 2 A water supply chamber 10 is provided between the guide plate 4 and the condenser plate 5. The inlet and outlet of the condenser pipe 7 are both connected to the water supply chamber 10. A micro water pump 11 is fixedly connected to the inlet of the condenser pipe 7. A water supply pipe 12 is fixedly inserted into the top of one side wall of the water supply chamber 10. A sealing cap is connected to the outside of the water supply pipe 12.

[0025] In practice, the miniature water pump 11 delivers water from the water supply chamber 10 to the condenser tube 7, enabling the cooling water in the condenser tube 7 to circulate and improve the cooling effect. The water supply chamber 10 can be replenished with water through the water filling pipe 12 to ensure that the condenser tube 7 can continue to work normally.

[0026] See Figure 1 and Figure 4 A feed hopper 13 is fixedly connected to the top of the coal mill box 1. Two grinding rollers 14 are provided at the bottom of the feed hopper 13. The two grinding rollers 14 are rotatably connected to the inner walls of the front and rear sides of the grinding chamber 2. A rotating shaft 15 is fixedly connected to the center of the two grinding rollers 14. The two rotating shafts 15 pass through one side of the outer wall of the coal mill box 1 and are fitted with a linkage belt 16. A fixing plate is fixedly connected to one side of the outer wall of the coal mill box 1. A motor 17 is installed on the fixing plate. The drive end of the motor 17 is fixedly connected to the center of one of the rotating shafts 15.

[0027] In practice, the material enters the grinding chamber 2 through the feed hopper 13. Inside the grinding chamber 2, the motor 17 drives the rotating shaft 15 to rotate, which in turn drives the two grinding rollers 14 to rotate via the linkage belt 16, grinding the incoming material. The ground material then enters the drying chamber 3 through the guide plate 4.

[0028] Working principle: First, the material enters the grinding chamber 2 through the feed hopper 13. Inside the grinding chamber 2, the motor 17 drives the rotating shaft 15 to rotate, which in turn drives the two grinding rollers 14 to rotate, grinding the incoming material. After grinding, the material enters the drying chamber 3 through the guide plate 4.

[0029] The hot air blower 6 inside the drying chamber 3 operates, blowing hot air into the drying chamber 3 to dry the materials entering the drying chamber 3. During the drying process, the moisture in the material will turn into water vapor and rise.

[0030] Because the top of the drying chamber 3 is equipped with an inclined condenser plate 5, and the inclination direction of the condenser plate 5 is opposite to that of the guide plate 4, the rising water vapor will condense into water droplets on its surface after encountering the condenser plate 5. When the generated water vapor is excessive, the condenser pipe 7 cools the excess steam in time, so that more steam condenses into water droplets.

[0031] The condensed water droplets flow downwards along the inclined direction of the condenser plate 5 and drip into the water collection tank 8. The water collection tank 8 collects the dripping condensate, preventing the condensate from dripping back onto the surface of the material being dried, thus ensuring the drying effect and speed.
