[0001] This utility model relates to the field of thermal power plant operation and detection technology, specifically to a dust removal device for a coal conveying system monitor in a thermal power plant. Background Technology

[0002] During the operation of thermal power plants, in order to avoid abnormalities in the internal equipment, it is necessary to monitor its operating parameters in real time. For example, the patent document with announcement number CN217442598U discloses a dust removal device for a coal conveying system monitor in a thermal power plant. This device can rotate and move the monitoring equipment through an adjustment mechanism to monitor parameters at different circumferential positions and angles, thereby significantly improving the monitoring range and enabling timely and flexible monitoring of real-time environmental parameters in the thermal power plant.

[0003] However, although the above-mentioned devices can monitor a large area inside the power plant, the operation of the thermal power plant will generate a lot of dust due to the transportation of fuels such as coal. As the dust increases and disperses, the outside of the monitoring components is easily covered with dust, which will cause the monitoring components to be obscured and affect the accuracy. Summary of the Invention

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model discloses a dust removal device for a monitor in a coal conveying system of a thermal power plant.

[0031] This utility model provides a dust removal device for a coal conveying system monitor in a thermal power plant, as shown in Figures 1-4. The device includes an installation plate 1 and a monitor 2 fixedly installed at the bottom of the installation plate 1. A support frame 3 is fixedly installed at the top of the installation plate 1. A rotating pipe 4 is rotatably connected to the support frame 3. The support frame 3 and the rotating pipe 4 can be rotatably connected by bearings. A dust removal block 5 is connected to the bottom of the rotating pipe 4. The dust removal block 5 is hollow and has multiple spaced air jet holes 6 on the side near the monitor 2.

[0032] An air pump 7 is fixedly installed on the top of the mounting plate 1. A hanger is fixedly installed on the outer wall of the air pump 7. The device is installed on the wall and top of the area to be monitored by the hanger. An air inlet pipe 8 and an air outlet pipe 9 are respectively connected to the two ends of the air pump 7. The upper end of the air outlet pipe 9 is rotatably inserted into the interior of the rotating pipe 4. Both the air outlet pipe 9 and the rotating pipe 4 are made of rigid plastic pipes to ensure the rotational stability between the air outlet pipe 9 and the rotating pipe 4. A control motor 10 is fixedly installed on the top of the inner wall of the support frame 3. A drive gear 11 is fixedly installed at the end of the output shaft of the control motor 10. A transmission gear 12 is fixedly installed on the upper end of the outer wall of the rotating pipe 4. The drive gear 11 and the transmission gear 12 are configured to cooperate. The control motor 10 rotates forward and backward to control the drive gear 11 and the transmission gear 12 to reciprocate, so that the rotating pipe 4 can drive the dust removal block 5 to blow air and remove dust over a large area outside the monitor 2.

[0033] To ensure that the gas emitted from inside the hollow block 5 is sufficiently clean, as shown in Figures 2 and 4, a filter tube 13 is fitted on the outer wall of the air intake pipe 8, and a filter screen 14 is fitted on the end of the filter tube 13 to filter the air and ensure that the gas is blown out cleanly. Multiple connecting bolts 16 arranged symmetrically around the opening of the filter screen 14 and the filter tube 13 are threaded through the tube, which facilitates the replacement of the filter screen 14. The filter tube 13 is an internally threaded tube, and the outer wall of the air intake pipe 8 is threaded with threads 15. The filter tube 13 is threaded on the outside of the air intake pipe 8, which allows for quick disassembly and assembly of the filter tube 13.

[0034] Specific working principle:

[0035] When it is necessary to monitor the operating parameters of the centralized control system of the thermal power plant in real time, the monitor 2 starts to work and monitors the relevant parameters. During the operation of the thermal power plant, dust in the environment is easy to adhere to the outer wall of the monitor 2, affecting the monitoring effect. At this time, the suction pump 7 and the control motor 10 are started.

[0036] The air intake pump 7 draws in outside air through the air intake pipe 8. Before entering the air intake pipe 8, the air is filtered by the filter pipe 13 and the filter screen 14. The filter screen 14 can block larger dust particles, and the filter pipe 13 further filters the air to remove tiny impurities, ensuring that the air entering the air intake pump 7 is relatively clean. Since the filter pipe 13 is an internally threaded pipe, it is matched with the thread 15 on the outer wall of the air intake pipe 8. The filter screen 14 and the pipe opening of the filter pipe 13 are connected by multiple symmetrically arranged connecting bolts 16, which facilitates the disassembly and replacement of the filter pipe 13 and the filter screen 14, and makes it convenient for regular cleaning and maintenance.

[0037] Filtered air, under the action of suction pump 7, enters rotating pipe 4 through air outlet pipe 9, and then flows into dust removal block 5. When control motor 10 rotates forward and backward, the drive gear 11 at the end of its output shaft rotates accordingly. Since drive gear 11 cooperates with transmission gear 12 at the upper end of the outer wall of rotating pipe 4, the rotation of drive gear 11 drives transmission gear 12 to rotate, thereby causing rotating pipe 4 to rotate back and forth. Rotating pipe 4 drives dust removal block 5 to rotate synchronously. Air jet holes 6 on dust removal block 5 blow out clean air from inside, performing air blowing and dust removal on the outer wall of monitor 2 over a large range. As rotating pipe 4 rotates, air jet holes 6 can cover different positions of monitor 2, ensuring that dust is effectively removed and keeping the exterior of monitor 2 clean, thereby improving monitoring clarity and accuracy.
