Description

Technical Field

[0001] The utility model relates to the technical field of coal-saving agent addition, in particular to a coal-saving agent addition device for a cement kiln furnace. Background Technique

[0002] The coal-saving agent mainly converts the flue gas generated by coal combustion into new combustible energy. At the same time, it promotes the sharp increase of the temperature of the inner flame of the flame and drives the sharp increase of the temperature of the outer flame of the flame, greatly increasing the flame length, flame density, and flame area, thereby improving the boiler output and saving a large amount of coal. When transporting coal, the additive is sprayed onto the coal on the conveyor belt through an adding device to achieve the adding effect.

[0003] At present, all existing coal-saving agent addition devices for cement kiln furnaces spray the coal-saving agent by using a nozzle during the process of coal transportation to achieve the addition of the coal-saving agent to the coal.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , an embodiment of the present utility model is: a coal-saving agent adding device for a cement kiln, including a belt scale 1, a conveyor belt 11 is arranged inside the belt scale 1, a blanking mechanism 2 is arranged on the belt scale 1, a side plate 4 is fixedly installed on the belt scale 1, a fixing frame 5 is arranged on the side plate 4, a coal-saving agent storage tank 6 is fixedly installed on the fixing frame 5, a variable-frequency metering pump 7 is fixedly installed on the upper surface of the fixing frame 5, a conveying pipe 9 is fixedly installed inside the fixing frame 5, and a nozzle 10 is fixedly installed at the bottom of the conveying pipe 9;

[0022] The blanking mechanism 2 includes a fixing plate 201 and a blanking hopper 208. The fixing plate 201 is fixedly installed on the blanking hopper 208.

A support frame 209 is fixedly installed at the bottom of the blanking hopper 208. A guide rod 206 is fixedly installed on the baffle plate 202. After the coal is blanked onto the conveyor belt 11 through the blanking hopper 208, by adjusting the position height of the baffle plate 202, the baffle plate 202 can level the coal piled up on the conveyor belt 11, and the scribing rod 207 is used to scribe a groove on the coal, so that the coal-saving agent can be evenly sprayed on the coal, avoiding the phenomenon of uneven spraying of the coal-saving agent caused by coal accumulation.

[0023] The support frame 209 is fixedly installed on the upper surface of the belt scale 1. A bearing 203 is fixedly installed on the upper surface of the baffle plate 202. The lower end of the threaded rod 204 is fixedly installed on the inner wall of the inner ring of the bearing 203. The rotation of the threaded rod 204 can be facilitated by the setting of the bearing 203 to adjust the position of the baffle plate 202.

[0024] An internal threaded hole is provided on the upper surface of the fixing plate 201. The threaded rod 204 is threadedly connected inside the internal threaded hole. A through hole is provided on the upper surface of the fixing plate 201. The guide rod 206 penetrates through the inside of the through hole. The setting of the guide rod 206 can play a role in limiting the baffle plate 202.

[0025] The variable frequency metering pump 7 is connected to the coal saver storage tank 6 through a liquid extraction pipe. The variable frequency metering pump 7 is connected to the conveying pipe 9 through a connecting pipe 8. By starting the variable frequency metering pump 7, the coal saver inside the coal saver storage tank 6 can be sprayed on the coal through the nozzle 10.

[0026] Working principle: When the coal is fed through the hopper 208 onto the conveyor belt 11, the operator rotates the handle 205 to drive the threaded rod 204 to adjust the up and down position of the baffle plate 202, so as to adjust the gap between the baffle plate 202 and the conveyor belt 11. The baffle plate 202 can level the coal piled up on the conveyor belt 11 and make grooves in the coal through the scribing rod 207, so that the coal saver can be evenly sprayed on the coal, avoiding the phenomenon of uneven spraying of the coal saver caused by coal accumulation.

[0027] Please refer to Figures 1-4 , on the basis of the above embodiment, in another embodiment of the present invention, a lapping mechanism 3 is provided on the side plate 4. The lapping mechanism 3 includes a slot 301 and a plug board 304. The slot 301 is provided on the side plate 4. The plug board 304 is inserted into the slot 301. The plug board 304 is fixedly installed at the bottom of the fixing frame 5. The setting of the lapping mechanism 3 can facilitate the quick lapping and installation of the fixing frame 5 on the side plate 4.

[0028] A jack 302 is provided on the side plate 4. A plug post 303 is inserted into the jack 302. The plug post 303 is fixedly installed at the bottom of the fixing frame 5. The setting of the jack 302 and the plug post 303 can play a role in positioning the fixing frame 5.

[0029] Working principle: When it is necessary to lap the fixing frame 5 on the side plate 4, the fixing frame 5 can be directly and quickly lapped on the side plate 4 through the insertion between the slot 301, the jack 302, the plug post 303 and the plug board 304, facilitating the quick assembly of the device.

[0030] When the device is in use, the signals of the belt scale 1 on the coal conveyor belt can be collected through the signal acquisition module. After being calculated by the PLC, the rotation speed of the variable-frequency metering pump 7 is controlled, so as to control the addition of the coal-saving agent to the coal according to a certain set ratio. The industrial analysis values of coal, the parameters of cement raw meal, the parameters of clinker, the real-time output of cement clinker, and the real-time consumption of head coal and tail coal in the cement kiln DCS system are collected through the communication and data acquisition module. The data calculates the real-time coal-saving effect of the coal-saving agent through the industrial control computer, and establishes a parameter AI mathematical model. If the coal-saving effect is lower than the expected value, the addition amount of the coal-saving agent is adjusted according to the AI mathematical model in which the parameters are interrelated, so as to achieve the expected coal-saving effect.

[0031] The utility model provides a device for adding a coal-saving agent to a cement kiln. There are many methods and ways to specifically implement this technical solution. The above description is only the preferred embodiment of the utility model.
