Description

Technical Field

[0001] This utility model relates to the field of wind-powered coal preparation machine technology, specifically to an anti-clogging device for the blower pipe of a wind-powered coal preparation machine. Background Technology

[0002] Coal is widely used as an energy source in various industries. After being mined, coal needs to undergo coal preparation processes to separate impurities and gangue from the raw coal. Currently, dry coal preparation is the most common process, which uses air-powered coal separators.

[0003] The existing wind-powered coal preparation machine lacks a mechanism to clean accumulated coal dust inside the blower duct. This leads to the accumulation of coal dust in the blower duct over a long period, causing blockages, reducing air pressure and air volume. Furthermore, the existing wind-powered coal preparation machine cannot filter and crush large coal particles, which can clog the collection pipe and affect the air intake efficiency. Therefore, a new technical solution needs to be designed to address these issues. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Example 1: Please refer to again Figure 1-5This utility model provides an anti-clogging device for the blower pipe of a wind-powered coal preparation machine, including a protective cover 100. An air separator 110 is fixedly connected to the inner side of the protective cover 100. A blower 120 is fixedly connected to one side of the air separator 110, and the blowers 120 are arranged sequentially from front to back. A collecting pipe 130 is fixedly connected to one side of the blower 120. An installation ring 140 is fixedly connected to the inner side of the collecting pipe 130. A screen 150 is screwed to the top of the installation ring 140. A first motor 160 is fixedly connected to the bottom of the screen 150. The top end of the power output shaft of the first motor 160 passes through the screen 150 and extends to the top of the screen 150. An installation chamber 170 is fixedly connected. Gear driven rods 171 are rotatably connected to both sides of the inner cavity of the installation chamber 170. The ends of the two gear driven rods 171 that are far apart from each other pass through the installation chamber 170 and extend to the outside of the installation chamber 170. A rolling roller 172 is fixedly connected to the ends of the two gear driven rods 171 that are far apart from each other. A second motor 180 is fixedly connected to the top of the installation chamber 170. The bottom end of the power output shaft of the second motor 180 passes through the installation chamber 170 and extends to the inner cavity of the installation chamber 170. A first drive gear 181 is fixedly connected to the bottom end of the power output shaft of the second motor 180. The first drive gear 181 is meshed with the gear driven rods 171.

[0022] Specifically, by starting the first motor 160 to drive the installation chamber 170 connected to it to rotate, the crushing roller 172 installed on the installation chamber 170 rotates around the installation chamber 170 as the center. At the same time, the second motor 180 is started to drive the first drive gear 181 to rotate, which in turn drives the two gear driven rods 171 meshing with it to rotate. This causes the crushing roller 172 installed on the gear driven rods 171 to rotate, crushing the large coal particles intercepted by the screen 150.

[0023] Example 2: Please refer to again Figure 1-5An air duct 200 is provided inside the protective cover 100. The air duct 200 is connected to the blower 120. A mounting bracket 210 is fixedly connected to the inside of the air duct 200. A rotating rod 220 is rotatably connected to the inside of the mounting bracket 210. Connecting brackets 230 are fixedly connected to both sides of the outer side of the rotating rod 220. A mounting plate 231 is fixedly connected to one side of the connecting bracket 230. A cleaning scraper 240 is fixedly connected to one side of the mounting plate 231. The cleaning scraper 240 is in contact with the air duct 200. The cleaning scraper 240 is a straight plate that is adapted to the cross-section of the inner wall of the air duct 200. The working edge of the cleaning scraper 240 is in close contact with the inner wall of the air duct 200. When the rotating rod 220 rotates, it drives the cleaning scraper 240 to move along the inner wall of the air duct to scrape off the coal dust accumulated on the inner wall of the air duct and prevent the air duct from being blocked. The cleaning scraper 240 is adapted to the cross-section of the inner wall of the air duct 200. The cleaning scraper 240 is a straight plate with its working edge in contact with the inner wall of the blower duct 200. When the rotating rod 220 rotates, it drives the cleaning scraper 240 to move along the inner wall of the blower duct to scrape off the coal dust accumulated on the inner wall of the blower duct and prevent the blower duct from getting blocked. A support rod 250 is fixedly connected to the lower side of the inner cavity of the blower duct 200. A transmission chamber 260 is fixedly connected to the top of the support rod 250. A driven gear 270 is fixedly connected to one end of the rotating rod 220. One end of the driven gear 270 passes through the transmission chamber 260 and extends into the inner cavity of the transmission chamber 260. A third motor 280 is fixedly connected to the top of the transmission chamber 260. The bottom end of the power output shaft of the third motor 280 passes through the transmission chamber 260 and extends into the inner cavity of the transmission chamber 260. A second drive gear 281 is fixedly connected to the bottom end of the power output shaft of the third motor 280. The second drive gear 281 meshes with the driven gear 270.

[0024] Specifically, by starting the third motor 280, the second drive gear 281 is driven to rotate, which in turn drives the driven gear 270 meshing with it to rotate, causing the rotating rod 220, which is driven by the gear, to rotate. The connecting frame 230 mounted on the rotating rod 220 follows the rotation of the rotating rod 220, causing the cleaning scraper 240 on the mounting plate 231 to rotate synchronously, so that the cleaning scraper 240 cleans the coal dust that is in contact with it and attached to the blower duct 200.

[0025] Working principle: The first motor 160 is started to drive the installation chamber 170 connected to it to rotate, so that the crushing roller 172 installed on the installation chamber 170 rotates around the installation chamber 170 as the center. At the same time, the second motor 180 is started to drive the first drive gear 181 to rotate, so that the first drive gear 181 drives the two gear driven rods 171 meshing with it to rotate, so that the crushing roller 172 installed on the gear driven rod 171 rotates on its own axis, crushing and breaking the large coal particles intercepted by the screen 150.

[0026] The third motor 280 is started to drive the second drive gear 281 to rotate, which in turn drives the driven gear 270 that meshes with it to rotate. This causes the rotating rod 220, which is driven by the gear, to rotate. The connecting frame 230 mounted on the rotating rod 220 rotates in sync with the rotation of the rotating rod 220, causing the cleaning scraper 240 on the mounting plate 231 to rotate synchronously. The cleaning scraper 240 cleans the coal dust that is in contact with it and attached to the blower duct 200.

[0027] It should be noted that the wind-powered coal preparation machine mainly consists of the following parts: Blowering system: including blowers and blower pipes, providing airflow power; Separation chamber: coal powder and airflow are separated here to achieve separation; Feeding device: feeding raw coal evenly into the separation chamber; Discharge device: including clean coal and tailings outlets, discharging the separated products respectively; Dust removal system: collecting and treating dust to reduce environmental pollution; Control system: adjusting parameters such as wind speed and wind pressure to optimize the separation effect; Support frame and outer shell: supporting the equipment and protecting the internal structure.

[0028] Working principle: The wind-powered coal preparation machine uses airflow to separate coal powder according to density and particle size. Light clean coal is carried away by the airflow, while heavy tailings settle and are discharged, thus realizing the separation and purification of coal.
