Description

Technical Field

[0001] The utility model belongs to the technical field of coal mills, and in particular relates to a coal mill capable of intelligent detection and improving combustion efficiency. Background Art

[0002] A coal mill is a mechanical device specifically designed to break up coal lumps and grind them into pulverized coal. It is a crucial auxiliary equipment for pulverized coal furnaces. The mill's operating principle primarily involves converting lumps of coal into pulverized coal through various crushing, pulverizing, and grinding methods. This process fragments the coal, increasing its surface area and requiring the intermolecular forces to be overcome, consuming energy. Coal is ground into pulverized coal in the mill primarily through crushing, pulverizing, and grinding. Crushing consumes the least energy, while grinding consumes the most. However, existing pulverizers still have certain shortcomings. For example, metallic impurities can be present in the coal lumps during feeding. If these impurities are not removed, they can damage the grinding mechanism within the mill. Furthermore, after the coal lumps are ground into pulverized coal, a fan mechanism is required to transport the pulverized coal to the outside of the mill. This fan mechanism delivers hot air, and the heat of the hot air determines the quality of the discharged coal. Existing pulverizers cannot monitor this data, necessitating improvements. Utility Model Content

[0003] The purpose of the present utility model is to provide a coal mill that can intelligently detect and improve combustion efficiency, aiming to solve the existing technology. However, there are still certain deficiencies in the use of existing coal mills. For example, when the coal mill is feeding, the coal blocks will contain some metal impurities. If these impurities are not removed, they will easily cause damage to the grinding mechanism in the coal mill after entering the coal mill. It is necessary to avoid the hardness of the metal impurities being greater than the hardness of the coal blocks. At the same time, after the coal blocks are ground into coal powder, the coal powder needs to be sent to the outside of the coal mill by an air supply mechanism, and the wind force determines the state of the coal powder discharge. The existing coal mill cannot detect data, and thus needs to be improved.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a coal mill capable of intelligent detection to improve combustion efficiency, comprising a coal mill body, an air inlet installed on the surface of the coal mill body, a temperature sensor connected to the bottom end of the air inlet, a feed port connected to the top end of the coal mill body, a discharge port connected to the top end of the coal mill body and located on both sides of the feed port, a baffle provided inside the feed port, the internal rotation of the feed port is connected to a rotating shaft, and a servo motor is installed on the outer wall of the feed port.

[0005] As a preferred embodiment of the coal mill capable of intelligent detection to improve combustion efficiency of the present invention, the output shaft of the servo motor is connected to one end of the rotating shaft, and the surface of the rotating shaft is connected to one end of the baffle.

[0006] As a preferred embodiment of the coal mill capable of intelligent detection and improving combustion efficiency of the utility model, the baffle is rotatably connected to the inside of the feed port via a rotating shaft.

[0007] As a preferred coal mill capable of intelligent detection and improving combustion efficiency of the utility model, the outer wall of the feed port is also connected to a box body, a screw rod is installed inside the box body, one end of the box body is connected to a bearing, and the surface of the screw rod is connected to a magnetic block.

[0008] As a preferred embodiment of the coal mill capable of intelligent detection and improving combustion efficiency of the present invention, the bearing is installed on the outer side wall of the feed port, and the screw rod extends to the inside of the feed port and is connected to the inner ring of the bearing.

[0009] As a preferred embodiment of the coal mill capable of intelligent detection and improving combustion efficiency of the present invention, a guide rod is further installed inside the box body, a first motor is installed on the outer side wall of the box body, and a scraper is installed inside the box body.

[0010] As a preferred embodiment of the utility model of a coal mill capable of intelligent detection to improve combustion efficiency, the top end of the scraper and the bottom end of the magnetic block are in the same straight line, and the magnetic block is threadedly connected to the surface of the screw rod and has both ends passing through the guide rod.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model utilizes the cooperation between the baffle and the magnetic block, which allows the magnetic block to move on the baffle, thereby absorbing metal impurities in the coal block placed on the baffle, preventing the metal impurities from entering the coal mill body along with the coal block, causing damage to the grinding mechanism in the coal mill body. At the same time, the temperature sensor can detect the air supply temperature at the air inlet, preventing the air supply temperature change from affecting the drying and discharging of the coal powder.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] See also Figure 1-4 The utility model provides the following technical solutions: a coal mill capable of intelligent detection to improve combustion efficiency, comprising a coal mill body 1, an air inlet 2 installed on the surface of the coal mill body 1, a temperature sensor 3 connected to the bottom end of the air inlet 2, a feed port 4 connected to the top end of the coal mill body 1, a discharge port 15 connected to the top end of the coal mill body 1 and located on both sides of the feed port 4, a baffle 5 is provided inside the feed port 4, the internal rotation of the feed port 4 is connected to the rotating shaft 6, and a servo motor 7 is installed on the outer wall of the feed port 4.

[0022] Preferably in the embodiment: the output shaft of the servo motor 7 is connected to one end of the rotating shaft 6 , and the surface of the rotating shaft 6 is connected to one end of the baffle 5 .

[0023] In the preferred embodiment, the baffle 5 is rotatably connected to the inside of the feed port 4 via a rotating shaft 6 .

[0024] In the preferred embodiment: the outer wall of the feed port 4 is further connected to a box body 8, a screw rod 9 is installed inside the box body 8, one end of the box body 8 is connected to a bearing 10, and the surface of the screw rod 9 is connected to a magnetic block 11.

[0025] In the preferred embodiment, the bearing 10 is mounted on the outer wall of the feed port 4 , and the screw rod 9 extends to the inside of the feed port 4 and is connected to the inner ring of the bearing 10 .

[0026] In the preferred embodiment, a guide rod 14 is further installed inside the box body 8 , a first motor 12 is installed on the outer side wall of the box body 8 , and a scraper 13 is installed inside the box body 8 .

[0027] In the preferred embodiment, the top end of the scraper 13 and the bottom end of the magnetic block 11 are in the same straight line, and the magnetic block 11 is threadedly connected to the surface of the screw rod 9 and both ends pass through the guide rod 14.

[0028] In the embodiment, firstly, the coal mill body 1 belongs to the existing mature technology, and the model of the coal mill body 1 is: LM130K, and thus the working principle of the coal mill body 1 will not be described in detail in this article.

[0029] In another embodiment, when the coal mill body 1 is in use, the discharge port 15 is connected to the pulverized coal combustion furnace through a pipe, and the air inlet 2 is connected to the air supply mechanism through a pipe. The above description belongs to the existing public technology and will not be elaborated on.

[0030] Working principle: The coal blocks are fed into the coal mill body 1 through the feed port 4. At this time, the coal blocks will fall on the baffle 5. Then the power is connected to start the first motor 12, and then the output shaft of the first motor 12 drives the screw rod 9 to rotate along the inner ring of the bearing 10 inside the box body 8 and the feed port 4. At the same time, the rotation of the screw rod 9 allows the magnetic block 11 to start approaching the feed port 4 along the surface thread. At the same time, the two ends of the magnetic block 11 will also slide along the surface of the guide rod 14. As the magnetic block 11 enters the feed port 4, it will be at the top of the baffle 5, and then the magnetic block 11 moves back and forth at the top of the baffle 5. Thus, the metal impurities in the coal blocks placed on the baffle 5 are adsorbed, preventing the metal impurities from entering the coal mill body 1 along with the coal blocks and causing damage to the grinding mechanism in the coal mill body 1. Then, the servo motor 7 works to allow the output shaft to drive the rotating shaft 6 to rotate, and the rotation of the rotating shaft 6 drives the baffle 5 to rotate, so that the coal blocks on the baffle 5 slide along the inclined angle of the baffle 5 to the inside of the coal mill body 1 for processing, and the magnetic block 11 is retracted into the inside of the box 8. Then, the scraper 13 scrapes off the metal impurities adsorbed on the magnetic block 11, making it easier for the magnetic block 11 to work next time.

[0031] At the same time, the air supply mechanism connected to the air inlet 2 through the pipeline can blow the pulverized coal inside the pulverizer body 1 to the discharge port 15, and then send it into the combustion furnace through the discharge port 15 for combustion. The temperature sensor 3 connected to the air inlet 2 can intelligently detect the air supply temperature of the air supply mechanism. The model of the temperature sensor 3 is: MLX90614, allowing hot air to dry the pulverized coal conveniently, and then send it into the combustion furnace through the discharge port 15 for combustion, further improving the combustion efficiency and avoiding the influence of heat changes on the normal drying of the pulverized coal.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
