Description

Technical Field

[0001] This utility model relates to a pulverizing device, specifically a coal powder pulverizing device for drying quartz sand, belonging to the technical field of pulverizing devices. Background Technology

[0002] Quartz sand is an important raw material in industries such as glass manufacturing, ceramic production, and casting. Its moisture content directly affects the quality of subsequent processed products, making drying an essential process. In some industrial production, the heat generated by burning pulverized coal is used to dry the quartz sand. The particle size of pulverized coal significantly affects combustion efficiency and heat release. Uniformly sized pulverized coal can burn completely, improving heat utilization. Therefore, high-quality pulverized coal crushing equipment is crucial. Generally, pulverized coal crushing equipment is equipped with a conveyor belt, which transports the crushed pulverized coal a certain distance, preventing it from accumulating at the bottom of the crushing device. The conveyor belt is typically wound around two winding rollers.

[0003] However, with increased usage time, conveyor belts can loosen due to wear, stretching, and other factors. Once loose, slippage can easily occur as the winding rollers rotate, leading to decreased conveying efficiency and severely impacting production schedules. Furthermore, conveyor belt slippage can cause coal dust to spill during transport, resulting in raw material waste and environmental pollution, increasing cleanup costs. Simultaneously, slippage exacerbates wear between the conveyor belt and the winding rollers, shortening their lifespan and increasing equipment maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a coal powder pulverizing device for drying quartz sand in order to solve the above problems. When the conveyor belt becomes loose, it can be quickly tensioned to avoid slippage during the movement of the conveyor belt driven by the winding roller, thus ensuring conveying efficiency and reducing problems such as raw material waste and equipment wear caused by slippage.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a coal powder pulverizing device for drying quartz sand, comprising a frame, an adjustment structure on the frame, a drive structure on the frame, the adjustment structure comprising a guide seat and a slide rod, two guide seats fixedly connected to the frame, a slide rod slidably connected to the guide seats, a guide shaft fixedly connected to the slide rod, two connecting shafts fixedly connected to the frame, a swing rod rotatably connected to the connecting shaft, a guide groove on the swing rod, the guide shaft extending into the interior of an adjacent guide groove and slidably connected to the swing rod, a common adjustment roller rotatably connected between the two swing rods, two winding rollers rotatably connected to the frame, a common conveyor belt wound on the two winding rollers, and the adjustment roller abutting against the conveyor belt.

[0006] Preferably, the diameter of the cross-sections at both ends of the adjusting roller is smaller than the diameter of the cross-section in the middle, and the cross-section of the slide rod is rectangular.

[0007] Preferably, the drive structure includes a rotating rod and a long shaft. The long shaft is rotatably connected to the frame, and two first gears are fixedly connected to the long shaft. The first gears mesh with the second gears. The second gear is fixedly connected to a lead screw. The lead screw is rotatably connected to a connecting seat. The connecting seat is fixedly connected to the frame. The lead screw and the slide rod are threaded together.

[0008] Preferably, a rotating rod is slidably connected to the long shaft, and the rotating rod is perpendicular to the lead screw.

[0009] Preferably, one of the winding rollers is fixedly connected to one of the pulleys, a motor is mounted on the frame, and another pulley is fixedly connected to the output shaft of the motor. The same belt is wound on both pulleys.

[0010] Preferably, a plurality of support rollers are rotatably connected to the frame, and the support rollers abut against the conveyor belt.

[0011] Preferably, the conveyor belt is fixedly connected with multiple protrusions, and the frame is fixedly connected with two baffles.

[0012] Preferably, a crushing box is installed on the frame, and a feeding hopper is fixedly connected to the top of the crushing box.

[0013] The beneficial effects of this utility model are as follows: During use, the conveyor belt can be driven by the rotation of the winding roller to transport the pulverized coal powder. When the conveyor belt becomes loose, the drive structure can drive two slide rods to slide simultaneously on two guide seats. The movement of the slide rods will drive the guide shaft to move. While the guide shaft moves inside the guide groove, it will push the swing rod to rotate around the connecting shaft. The simultaneous rotation of the two swing rods will drive the adjusting roller to move, thereby rapidly changing the position of the adjusting roller. During the change of position, the adjusting roller will tighten the conveyor belt. Therefore, when the conveyor belt becomes loose, it can be quickly tightened, thereby avoiding slippage during the movement of the conveyor belt driven by the winding roller, ensuring conveying efficiency, and reducing problems such as raw material waste and equipment wear caused by slippage.

[0019] 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.

[0020] Please see Figures 1-4 As shown, a coal powder pulverizing device for drying quartz sand includes a frame 1, an adjusting structure 2 and a driving structure 3 on the frame 1. The adjusting structure 2 includes a guide seat 201 and a slide rod 202. Two guide seats 201 are fixedly connected to the frame 1, and a slide rod 202 is slidably connected to the guide seat 201. A guide shaft 203 is fixedly connected to the slide rod 202. Two connecting shafts 206 are fixedly connected to the frame 1. A swing rod 205 is rotatably connected to the connecting shaft 206. A guide groove 204 is provided on the swing rod 205. The guide shaft 203 extends into the interior of the adjacent guide groove 204 and is slidably connected to the swing rod 205. The same adjusting roller 207 is rotatably connected between the two swing rods 205. Two winding rollers 6 are rotatably connected to the frame 1. The same conveyor belt 4 is wound on the two winding rollers 6. The adjusting roller 207 abuts against the conveyor belt 4.

[0021] As a technical optimization of this utility model, the diameter of the cross-sections at both ends of the adjusting roller 207 is smaller than the diameter of the cross-section in the middle, and the cross-section of the slide rod 202 is rectangular. Therefore, the slide rod 202 can only slide on the guide seat 201 and cannot rotate with the lead screw 306.

[0022] As a technical optimization of this utility model, the drive structure 3 includes a rotating rod 301 and a long shaft 302. The long shaft 302 is rotatably connected to the frame 1. Two first gears 303 can be connected through the long shaft 302. Therefore, when the long shaft 302 is rotated, the two first gears 303 can rotate simultaneously. Two first gears 303 are fixedly connected to the long shaft 302. The first gears 303 mesh with the second gear 304. The second gear 304 is fixedly connected to the lead screw 306. By rotating the lead screw 306, the position of the slide rod 202 can be precisely adjusted. The lead screw 306 is rotatably connected to the connecting seat 305. The connecting seat 305 is fixedly connected to the frame 1. The connecting seat 305 can support the lead screw 306. The lead screw 306 and the slide rod 202 are threadedly connected.

[0023] As a technical optimization of this utility model, a rotating rod 301 is slidably connected on the long shaft 302, and the long shaft 302 can be easily rotated by holding the rotating rod 301. The rotating rod 301 is perpendicular to the lead screw 306.

[0024] As a technical optimization of this utility model, one of the winding rollers 6 is fixedly connected to one of the pulleys 7, a motor 9 is installed on the frame 1, and another pulley 7 is fixedly connected to the output shaft of the motor 9. The same belt 8 is wound on the two pulleys 7. When one of the pulleys 7 on the motor 9 rotates, it can drive the other pulley 7 on one of the winding rollers 6 to rotate through the belt 8. Therefore, the rotation of one of the winding rollers 6 can be controlled by the motor 9.

[0025] As a technical optimization of this utility model, a plurality of support rollers 10 are rotatably connected on the frame 1, and the support rollers 10 can support the conveyor belt 4, and the support rollers 10 and the conveyor belt 4 are in contact.

[0026] As a technical optimization of this utility model, multiple protrusions 5 are fixedly connected to the conveyor belt 4. The protrusions 5 can prevent coal powder from slipping on the inclined conveyor belt 4, thereby improving the stability of the conveying. Two baffles 11 are fixedly connected to the frame 1. The baffles 11 can block the two sides of the conveyor belt 4 to prevent coal powder from spilling from the two sides of the conveyor belt 4.

[0027] As a technical optimization of this utility model, a crushing box 12 is installed on the frame 1, which can crush coal blocks. A feeding hopper 13 is fixedly connected to the top of the crushing box 12, which can conveniently add coal blocks into the crushing box 12 for crushing.

[0028] In use, the coal blocks to be crushed are added to the inside of the feeding hopper 13. The coal blocks fall from the bottom of the feeding hopper 13 into the crushing box 12 for crushing. The crushed coal powder falls onto the surface of the conveyor belt 4. At this time, the motor 9 rotates, driving one of the pulleys 7 to rotate. One of the pulleys 7 drives another pulley 7 to rotate via the belt 8. The rotation of the other pulley 7 drives one of the winding rollers 6 to rotate. The rotation of the winding roller 6 drives the conveyor belt 4 to move, thereby realizing the conveying of the crushed coal powder. When the conveyor belt 4 becomes loose, the long shaft 302 can be rotated by hand-held rotating rod 301. The rotation of the long shaft 302 drives two first gears 303 to rotate. The first gears 303 drive the second gear 304 to rotate. The second gear 304 drives the lead screw 306 to rotate on the connecting seat 305. The rotation of the lead screw 306 drives the slide bar 202 to slide on the guide seat 201. The movement of the slide bar 202 drives the guide shaft 203 to move. While the guide shaft 203 moves inside the guide groove 204, it pushes the rocker arm 205 to rotate around the connecting shaft 206. The simultaneous rotation of the two rocker arms 205 drives the adjusting roller 207 to move, thereby rapidly changing the position of the adjusting roller 207. During the position change, the adjusting roller 207 tightens the conveyor belt 4. Therefore, when the conveyor belt 4 becomes loose, it can be quickly tightened, thereby avoiding slippage during the movement of the conveyor belt 4 driven by the winding roller 6, ensuring conveying efficiency, and reducing problems such as material waste and equipment wear caused by slippage.
