Description

Technical Field

[0001] The utility model relates to the technical field of combustion control, in particular to an intelligent combustion regulation device for a coal-fired boiler. Background Technique

[0002] A coal-fired boiler is a traditional heating device, which is widely used in industrial production to provide high temperature and a large amount of heat energy for raw material processing, reaction or steam generation. It can be used for heating and power generation. Coal-fired boilers are also used in some specific industrial heat treatment processes, such as calcination, drying, etc. These processes require high temperature and stable heat energy supply. The combustion regulation device of a coal-fired boiler is to optimize the combustion process, improve energy utilization efficiency, and reduce environmental pollution at the same time.

[0003] After retrieval, the text of the publication number "CN217004526U" mentions that "the utility model relates to the technical field of combustion control, specifically to a combustion control device for an efficient coal-fired boiler. It includes an air inlet pipe, and the air inlet pipe includes a horizontal section, a connecting section and a vertical section. A baffle is hinged at the inner wall position of the connecting section, a handle is installed on one side of the front of the connecting section, a scale line is arranged on one side of the front of the connecting section, and a number of air inlet branch pipes communicating with the air inlet pipe are obliquely installed on the outer wall position of the vertical section. A first fan is installed at one end of the air inlet branch pipe far away from the air inlet pipe, and an elliptical ball-shaped housing is installed in the middle position of the air inlet branch pipe. A conical spring is fixedly arranged in the middle of the inner cavity of the housing, and a sealing ball capable of sealing the air inlet end at the bottom of the housing is fixedly arranged at the bottom position of the conical spring. It has a variety of adjustment methods and a large adjustment range, so as to meet different air intake amounts." When in use, when it is necessary to adjust the air intake amount and the combustion speed, firstly, the position of the baffle can be adjusted through the handle (the handle is installed on the inner wall of the connecting section through a damping rotating shaft), and secondly, an appropriate number of first fans can be selected to be enabled. When the first fan is working, the blown air flow will overcome the elastic force of the conical spring and lift the sealing ball to increase the air intake. The use of the blocking ball can prevent the dust in the air inlet pipe from entering the first fan through the air outlet of the first fan when the first fan is not in use, resulting in damage to the first fan. However, this device uses wind force to overcome the elastic force of the conical spring and lift the sealing ball, resulting in relatively large energy waste, and there may be defects in the blocking effect of the blocking ball after the spring performance is damaged, and it cannot effectively isolate dust. Content of the Utility Model

When it needs to be adjusted downwards, the driving motor is started to provide power to drive the driving gear to rotate, so that the toothed ring meshed with the driving gear rotates, and the movable orifice plate rotates accordingly, causing the holes to be misaligned with the fixed orifice plate, thereby making the channel for the wind force to pass through smaller and reducing the air input.

[0015] 2. Air enters through the fan-shaped groove of the pipe. The fan-shaped filter screen blocks dust in the air from entering the pipe body. After the fan-shaped filter screen is used for a certain period of time, rotate the support ring to block the new fan-shaped filter screen at the air flow port. There is no need to stop the device to replace the filter element, which is relatively convenient. The fan-shaped filter screen can be disassembled and assembled on the support ring with screws.

[0022] Embodiment 1

[0024] The adjusting mechanism 2 includes a ventilation component 21, a limiting component 22, a shielding component 23 and a driving component 24. A ventilation component 21 is installed at the top end of the pipe body 1, a limiting component 22 is installed at the top end of the ventilation component 21, a shielding component 23 is installed inside the limiting component 22, and a driving component 24 is installed on one side of the limiting component 22.

[0025] Furthermore, the ventilation component 21 includes an outward expanding pipe 211 and a fixed orifice plate 212. The top end of the pipe body 1 is fixedly connected to the outward expanding pipe 211, and the inner side of the outward expanding pipe 211 is fixedly connected to the fixed orifice plate 212. The outward expanding pipe 211 expands the bearing range so that the diameter of the fixed orifice plate 212 matches that of the pipe body 1. The holes opened in the fixed orifice plate 212 are part of the air circulation path.

[0026] Furthermore, the limiting component 22 includes a lower limiting ring 221, a supporting bracket 222 and an upper limiting ring 223. The top end of the outward expanding pipe 211 is installed with the lower limiting ring 221. The outer side of the lower limiting ring 221 is fixedly connected to the supporting bracket 222. One side of the supporting bracket 222 is fixedly connected to the upper limiting ring 223. The lower limiting ring 221 and the upper limiting ring 223 provide limiting support for the toothed ring 231, and the supporting bracket 222 provides support for the driving component 24.

[0027] Furthermore, the shielding component 23 includes a toothed ring 231 and a movable orifice plate 232. The inner side of the lower limiting ring 221 is rotationally connected to the toothed ring 231 through a card slot. The inner side of the toothed ring 231 is fixedly connected to the movable orifice plate 232. The toothed ring 231 drives the movable orifice plate 232 to rotate, and the holes of the movable orifice plate 232 and the fixed orifice plate 212 are misaligned, so that the channel through which the wind passes becomes smaller and the air input is reduced.

[0028] Furthermore, the driving component 24 includes a driving motor 241 and a driving gear 242. The driving motor 241 is installed on the surface of the supporting bracket 222. The bottom end of the driving motor 241 is key-connected to the driving gear 242. The driving motor 241 provides power to drive the driving gear 242 to rotate, so that the toothed ring 231 meshed with the driving gear 242 rotates.

[0029] Embodiment 2

[0030] Please refer to Figure 2 As shown, compared with Embodiment 1, as another implementation manner of the present utility model, a sealing component 3 is installed at the top end of the upper limiting ring 223. The sealing component 3 includes a sector groove pipe slot 31 and a limiting support block 32. The top end of the upper limiting ring 223 is fixedly connected to the sector groove pipe slot 31, and the outer side of the sector groove pipe slot 31 is fixedly connected to the limiting support block 32. Air enters the pipe body 1 through the adjusting mechanism 2 from the sector groove pipe slot 31, and the limiting support block 32 provides rotational support for the filtering component 4.

[0031] Furthermore, a filtering assembly 4 is installed at the top end of the limit support block 32. The filtering assembly 4 includes a support ring 41 and a sector-shaped filter screen 42. The top end of the limit support block 32 is rotationally connected to the support ring 41 through a shaft. The top end of the support ring 41 is screw-connected to the sector-shaped filter screen 42. The sector-shaped filter screen 42 blocks dust in the air from entering the pipe body 1. After the sector-shaped filter screen 42 is used for a certain period of time, the support ring 41 is rotated to block the new sector-shaped filter screen 42 at the air flow port. It is not necessary to stop the device operation to replace the filtering element, which is relatively convenient. The sector-shaped filter screen 42 can be disassembled and assembled on the support ring 41 through screws.

[0032] Working principle: First, move a coal-fired boiler intelligent combustion control device to the working position. When in use, in the first step, the fan is installed below the pipe body 1 to provide power. Air enters the pipe body 1 from the sector-shaped groove tube groove 31 through the adjusting mechanism 2. The limit support block 32 provides rotational support for the filtering assembly 4. In the second step, the sector-shaped filter screen 42 blocks dust in the air from entering the pipe body 1. After the sector-shaped filter screen 42 is used for a certain period of time, the support ring 41 is rotated to block the new sector-shaped filter screen 42 at the air flow port. It is not necessary to stop the device operation to replace the filtering element, which is relatively convenient. The sector-shaped filter screen 42 can be disassembled and assembled on the support ring 41 through screws. In the third step, when all the holes of the fixed orifice plate 212 and the movable orifice plate 232 are aligned, it is the maximum wind force. At this time, the clean air enters the coal-fired boiler through the fan, reducing the impact of dust in the air on the fan and the coal-fired boiler. In the fourth step, when it needs to be adjusted downwards, the driving motor 241 provides power to drive the driving gear 242 to rotate, so that the toothed ring 231 engaged with the driving gear 242 rotates. The toothed ring 231 drives the movable orifice plate 232 to rotate, and the holes of the movable orifice plate 232 and the fixed orifice plate 212 are misaligned, so that the channel for the wind force to pass through becomes smaller, reducing the air input. In this way, the use process of a coal-fired boiler intelligent combustion control device is completed.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
