Description

Technical Field

[0001] This utility model relates to the field of bucket elevator technology, specifically a bucket elevator with real-time monitoring of the number of buckets being lifted. Background Technology

[0002] Coal bucket elevators are high-efficiency, continuous vertical conveying equipment specifically designed for bulk materials such as coal. Their structure mainly consists of a traction component (belt or chain), buckets, a drive unit, and a casing. The circularly moving buckets scoop coal from the bottom and vertically lift it to the top discharge port. They feature good sealing, large conveying capacity, and low power consumption, effectively preventing coal breakage and dust emission. Widely used in coal transfer processes in thermal power plants, coal washing plants, and coking plants, they are adaptable to ambient temperatures from -20°C to +40°C, with a single unit capable of lifting up to 50 meters and handling up to 300 cubic meters per second. 3 / h is one of the key pieces of equipment for vertical conveying in the coal industry.

[0003] Chinese Patent Publication No. CN 115303719 A discloses a "bucket elevator," comprising a shell, a conveyor belt, a material holding plate, a transmission mechanism, a locking mechanism, an adjusting mechanism, multiple baffle shells, and multiple buckets. The conveyor belt is rotatably arranged; the shell contains a top pulley and a bottom pulley for the conveyor belt to wind around, and a discharge port is provided at the upper end of the shell; multiple buckets are evenly distributed along the winding direction of the conveyor belt, and each bucket has an arc-shaped bottom and an upper opening structure; each baffle shell is installed on the side wall of a bucket, initially positioned at the upper end of the side wall of the bucket. This bucket elevator, by configuring a material holding plate and an adjusting mechanism in cooperation, can automatically adjust the position of the baffle shells according to the amount of material accumulated on the material holding plate. The large space occupied inside the bucket allows for a higher material spillage rate and reduces material falling. However, as it is a fully enclosed device, it is inconvenient to observe the internal working status and cannot monitor the bucket status in real time. If the bucket falls off, it may enter the main belt, causing impurities in the coal, or the fallen bucket may get stuck under the bucket elevator, causing equipment shutdown or even damage. Too many missing buckets can also cause blockages, thus affecting the efficiency of sampling operations. Furthermore, the buckets of the elevator are inconvenient to disassemble and install, making it difficult to quickly replace them according to different coal particle sizes, moisture content, or conveying capacity requirements, affecting equipment adaptability and maintenance efficiency. New technical solutions need 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 1-4 This utility model provides a bucket elevator with real-time monitoring of the number of buckets, including an elevator chamber 100. A discharge port 110 is integrally formed on one side of the elevator chamber 100, and a feed port 120 is fixedly connected to the other side. A drive roller 130 is rotatably connected to the lower side of the inner wall of the elevator chamber 100, and a driven roller 140 is rotatably connected to the upper side of the inner wall of the elevator chamber 100. Both the drive roller 130 and the driven roller 140 have slots 150 evenly distributed on their outer sides. A conveyor belt 160 is sleeved between the outer sides of the drive roller 130 and the driven roller 140, and a clamp is fixedly connected to one side of the conveyor belt 160. The lifting chamber 100 has a strip 161, and the strips 161 are evenly distributed. The strips 161 are engaged with the slots 150. A motor 170 is fixedly connected to one side of the lifting chamber 100. One end of the power output shaft of the motor 170 passes through the lifting chamber 100 and extends into the inner cavity of the lifting chamber 100. The other end of the power output shaft of the motor 170 is fixedly connected to the drive roller 130. Two through slots 180 are opened on both sides of the lifting chamber 100. Two mounting plates 190 are fixedly connected to both sides of the lifting chamber 100. An infrared signal transmitter 191 is fixedly connected to the top of one mounting plate 190, and an infrared signal receiver 192 is fixedly connected to the top of the other mounting plate 190.

[0022] Specifically, an infrared signal transmitter 191 and an infrared signal receiver 192 installed on both sides of the lifting chamber 100 form a beam channel. When the lifting hopper 210 passes through, it will block the light, causing the photoelectric signal of the infrared signal receiver 192 to change. By counting the number of times the photoelectric signal is interrupted by the infrared signal receiver 192, the number of buckets can be calculated. When a bucket falls or the operation is abnormal, an alarm message will be sent to the staff, and relevant personnel will take effective countermeasures to avoid serious failures.

[0023] Example 2: Please refer to again Figure 1-4The lifting chamber 100 has an internal mounting base 200. Specifically, the mounting base 200 is fixedly connected to the outside of the conveyor belt 160, and the mounting bases 200 are arranged evenly in sequence. A lifting hopper 210 is provided on one side of the mounting base 200, and a locking block 211 is fixedly connected to one side of the lifting hopper 210. The locking block 211 engages with the mounting base 200, and a positioning block 212 is fixedly connected to the top of the locking block 211. The mounting base 200 has two mounting grooves 220 inside, and the inner cavity of the mounting grooves 220 slides... The movable connection is a positioning tenon 221. One end of the positioning tenon 221 passes through the mounting groove 220 and the lifting hopper 210 and extends into the interior of the mounting base 200. A compression spring 230 is embedded in the inner cavity of the mounting groove 220. One end of the positioning tenon 221 is fixedly connected to a lever plate 240. The top of the lever plate 240 extends to the top of the mounting base 200. One side of the lever plate 240 is fixedly connected to a positioning tenon 241. One end of the positioning tenon 241 passes through the positioning block 212 and extends to the other side of the positioning block 212.

[0024] Specifically, by moving the two side plates 240, the positioning tenons 221 are pushed against the compression spring 230, thus releasing the fixation of the lifting hopper 210. At the same time, the positioning tenons 241 on the side plates 240 are also moved out of the positioning block 212. Then, the lifting hopper 210 can be removed from the mounting base 200. Subsequently, the locking block 211 on one side of the lifting hopper 210 to be used is engaged with the mounting base 200, so that the lifting hopper 210 is connected to the mounting base 200. Then, the side plates 240 are released, so that the compressed compression spring 230 is reset and deformed, pushing the positioning tenons 221 to move, so that the positioning tenons 221 are inserted into the lifting hopper 210. At the same time, the positioning tenons 241 on the side plates 240 are also inserted into the positioning block 212 on the locking block 211.

[0025] Working principle: The infrared signal transmitters 191 and infrared signal receivers 192 installed on both sides of the lifting chamber 100 form a beam channel. When the lifting bucket 210 passes through, it will block the light, causing the photoelectric signal of the infrared signal receiver 192 to change. By counting the number of photoelectric signal interruptions by the infrared signal receiver 192, the number of buckets can be calculated. When a bucket falls or the operation is abnormal, an alarm message will be sent to the staff, and relevant personnel will take effective measures to avoid serious failures.

[0026] By moving the two side plates 240, the positioning tenons 221 are pressed against the compression spring 230, thus releasing the fixation of the lifting hopper 210. At the same time, the positioning tenons 241 on the side plates 240 are also moved out of the positioning block 212. Then, the lifting hopper 210 can be removed from the mounting base 200. Subsequently, the locking block 211 on one side of the lifting hopper 210 to be used is engaged with the mounting base 200, so that the lifting hopper 210 is connected to the mounting base 200. Then, the side plates 240 are released, so that the compressed compression spring 230 is reset and deformed, pushing the positioning tenons 221 to move, so that the positioning tenons 221 are inserted into the lifting hopper 210. At the same time, the positioning tenons 241 on the side plates 240 are also inserted into the positioning block 212 on the locking block 211.
