Description

Technical Field

[0001] This utility model relates to the technical field of coal powder additive feeding devices, specifically a coal powder additive feeding device with an alarm function. Background Technology

[0002] Currently, coal is an important energy source in my country and is widely used in industries such as thermal power generation and urban heating. However, due to the structure and composition of coal itself, it cannot be completely burned during combustion, resulting in low combustion efficiency and the generation of a large amount of air pollutants after combustion. In order to improve the combustion efficiency of coal and reduce the air pollutants emitted during combustion, the main method in the existing technology is to add coal powder additives to improve the combustion efficiency of coal and reduce the emission of air pollutants. The combustion of coal powder additives mixed with coal can improve the completeness of coal combustion.

[0003] The existing patent CN214569189U discloses a coal powder additive feeding device with an alarm function, including a discharge port placed above the coal powder conveyor belt. The discharge port is located at the end of the auger feeder, which is connected to the feeder pipe. A blockage alarm device passes through the feeder pipe wall and is installed on the feeder pipe wall. This utility model can uniformly mix the coal powder additive with the coal powder and has a blockage alarm device. Once the additive becomes damp and blocks the material, it can be detected and dealt with in a timely manner.

[0004] However, the existing patent technology (publication number CN214569189U) cannot clear blockages in a timely manner when they occur, requiring manual clearing by staff, which is time-consuming and labor-intensive. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a coal powder additive feeding device with an alarm function to solve the problem mentioned in the background art that it cannot clear blockages in time when they occur, and that manual clearing by staff is required, which is time-consuming and labor-intensive.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a coal powder additive feeding device with alarm function, comprising a main body and a stirring mechanism, wherein the stirring mechanism is located inside the main body, and the main body includes a support frame, a hopper and a feeding pipe, wherein the hopper is fixedly installed at the upper end of the support frame and the feeding pipe is fixedly installed at the upper end of the hopper;

[0009] Preferably, the main structure further includes a feed pipe, a branch pipe, a rotary level switch, an anti-clogging component, and an audible and visual alarm. The feed pipe is fixedly installed at the lower end of the hopper, the branch pipe is fixedly installed at the left end of the feed pipe, the rotary level switch is fixedly installed inside the branch pipe, the anti-clogging component is fixedly installed on the right side of the feed pipe, and the audible and visual alarm is fixedly installed at the upper end of the hopper. In use, the coal powder additive is discharged through the feed pipe. When a blockage occurs, the coal powder additive will accumulate at the bottom of the pipe and rise into the branch pipe, hindering the rotation of the blades on the rotary level switch. At this time, the rotary level switch judges that a blockage has occurred, causing the audible and visual alarm to sound an alarm to remind the staff. Then, the anti-clogging component is activated, and a hammer driven by a hydraulic device strikes the feed pipe, causing the coal powder additive accumulated inside the feed pipe to be vibrated and cleared, avoiding affecting the feeding of coal powder additive and effectively improving the anti-clogging effect of the device.

[0010] Preferably, the anti-clogging component includes a mounting base, a hydraulic actuator, and a hammer, with the mounting base fixedly installed at the lower end of the support frame.

[0011] Preferably, the hydraulic actuator is fixedly installed on the left end of the mounting base, and the hammer is fixedly installed on the drive end of the hydraulic actuator. The hydraulic actuator can drive the hammer to strike the feed pipe, causing the coal powder additives accumulated inside the feed pipe to be vibrated and cleared.

[0012] Preferably, the stirring mechanism includes a drive motor, a rotating shaft, a stirring rod, and crushing discs, with the drive motor fixedly installed at the upper end of the hopper.

[0013] Preferably, the rotating shaft is fixedly installed at the drive end of the drive motor, and the stirring rod is fixedly installed at the outer end of the rotating shaft. When storing coal powder additives in the silo, the drive motor can drive the stirring rod to rotate, and the stirring rod can be used to stir the coal powder additives to make the coal powder additives evenly mixed.

[0014] Preferably, the crushing disc is fixedly installed on the outer end of the stirring rod, and the crushing disc is evenly distributed on the outer end of the stirring rod. When the stirring rod rotates, it can drive the crushing disc to rotate at the same time, thereby using the crushing disc to break up the clumps of coal powder additives and avoid blockage caused by the clumps of coal powder additives.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This coal powder additive feeding device with alarm function, through the installation of the main structure, enables the coal powder additive to be discharged through the discharge pipe during use. When a blockage occurs, the coal powder additive will accumulate at the bottom of the pipe and rise into the branch pipe, obstructing the rotation of the blades on the rotary level switch. At this time, the rotary level switch judges that a blockage has occurred, causing the audible and visual alarm to sound an alarm to remind the staff. Then, the anti-blockage component is activated, and the hydraulic device drives the hammer to strike the discharge pipe, causing the coal powder additive accumulated inside the discharge pipe to be vibrated and cleared, avoiding affecting the feeding of coal powder additive. This effectively improves the anti-blockage effect of the device and enhances the practicality of the coal powder additive feeding device with alarm function.

[0017] 2. This coal powder additive feeding device with alarm function, through the installation of a stirring mechanism, enables the stirring rod to rotate via a drive motor when storing coal powder additives in the silo. The stirring rod stirs the coal powder additives, making them evenly mixed. The rotation of the stirring rod also drives the crushing disc to rotate, thereby breaking up any clumps of coal powder additives and preventing blockages caused by clumping. This improves the effectiveness of the coal powder additive feeding device with alarm function. Attached Figure Description

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.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a coal powder additive feeding device with alarm function, including a main body 1 and a stirring mechanism 2. The stirring mechanism 2 is located inside the main body 1. The main body 1 includes a support frame 101, a hopper 102 and a feeding pipe 103. The hopper 102 is fixedly installed on the upper end of the support frame 101 and the feeding pipe 103 is fixedly installed on the upper end of the hopper 102.

[0025] The main structure 1 also includes a feed pipe 104, a branch pipe 105, a rotary level switch 106, an anti-blocking component 107, and an audible and visual alarm 108. The feed pipe 104 is fixedly installed at the lower end of the hopper 102, the branch pipe 105 is fixedly installed at the left end of the feed pipe 104, the rotary level switch 106 is fixedly installed inside the branch pipe 105, the anti-blocking component 107 is fixedly installed on the right side of the feed pipe 104, and the audible and visual alarm 108 is fixedly installed at the upper end of the hopper 102. The anti-blocking component 107 includes a mounting base 1071, a hydraulic actuator 1072, and a hammer 1073. The mounting base 1071 is fixedly installed at the lower end of the support frame 101, and the hydraulic actuator 1072 is fixedly installed at the upper end of the hopper 102. Installed on the left end of the mounting base 1071, the hammer 1073 is fixedly installed on the drive end of the hydraulic device 1072. During use, the coal powder additive is discharged through the feed pipe 104. When a blockage occurs, the coal powder additive will accumulate at the bottom of the pipe and rise into the branch pipe 105, hindering the rotation of the blades on the rotary level switch 106. At this time, the rotary level switch 106 judges that a blockage has occurred, causing the audible and visual alarm 108 to sound an alarm to remind the staff. Then the anti-blockage component 107 is activated, and the hammer 1073 is driven by the hydraulic device 1072 to strike the feed pipe 104, so that the coal powder additive accumulated inside the feed pipe 104 is vibrated and cleared, thus avoiding affecting the feeding of coal powder additive.

[0026] The mixing mechanism 2 includes a drive motor 201, a rotating shaft 202, a mixing rod 203, and a crushing disc 204. The drive motor 201 is fixedly installed at the upper end of the hopper 102, the rotating shaft 202 is fixedly installed at the drive end of the drive motor 201, the mixing rod 203 is fixedly installed at the outer end of the rotating shaft 202, and the crushing disc 204 is fixedly installed at the outer end of the mixing rod 203. The crushing disc 204 is evenly distributed at the outer end of the mixing rod 203. When storing coal powder additives in the hopper 102, the drive motor 201 can drive the mixing rod 203 to rotate, and the mixing rod 203 can stir the coal powder additives to make them evenly mixed. When the mixing rod 203 rotates, it can simultaneously drive the crushing disc 204 to rotate, thereby breaking up any clumps of coal powder additives and preventing blockages caused by coal powder additive clumping.

[0027] Working principle: When storing coal powder additives in the silo 102, the drive motor 201 drives the stirring rod 203 to rotate, stirring the coal powder additives to make them evenly mixed. When the stirring rod 203 rotates, it also drives the crushing disc 204 to rotate, thereby breaking up any clumps of coal powder additives and preventing blockages caused by clumping. When in use, the coal powder additives are discharged through the discharge pipe 104. When a blockage occurs, the coal powder additives will accumulate at the bottom of the pipe and rise into the branch pipe 105, obstructing the rotation of the blades on the rotary level switch 106. At this time, the rotary level switch 106 determines that a blockage has occurred, causing the audible and visual alarm 108 to sound an alarm to remind the staff. Then, the anti-blockage component 107 is activated, driving the hammer 1073 through the hydraulic device 1072 to strike the discharge pipe 104, causing the coal powder additives accumulated inside the discharge pipe 104 to be vibrated and cleared, thus preventing any impact on the feeding of coal powder additives.

[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
