Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a crushing device with a filtering structure. Background Art

[0002] A crushing device is a device used to crush, break or refine materials. In the mining industry, after ore is crushed and processed, it can be applied in multiple industries and engineering fields. The newly mined ore needs to be crushed first, and at the same time, impurities in the ore fragments need to be removed and filtered. Since the ore fragments have specific particle size requirements, the crushed materials need to be filtered to separate materials of different particle sizes, and then transported to various different processing sites according to the size of the ore fragments.

[0003] Among them, Chinese Patent (CN221334436U) discloses an ore crushing device with a filtering function, which can reciprocate the filter screen to filter the ore fragments, and at the same time extend the residence time of the ore fragments on the screen, so that the ore fragments are filtered more fully, thereby improving the filtering efficiency of the ore fragments. The utility model includes a bracket, a dust-proof housing, etc.; a dust-proof housing is fixedly connected to the top of the bracket. The motor drives two crushing gears to rotate towards each other through the output shaft, so that the ore is crushed by the two crushing gears pressing against each other. When the ore is crushed, the ore fragments fall downward due to gravity, and then the ore fragments fall on the screen, and the screen quickly filters out the fine impurities in the ore fragments, making the filtering process of the ore fragments more convenient and fast, thereby improving the filtering efficiency of the ore fragments.

[0004] At present, the crushing devices with filtering structures on the market have the same disadvantages as the above-mentioned comparative document: Although the diversion plate and the shunt plate are used to improve the residence time of the crushed stones on the screen to screen the crushed stones of different sizes, when a large amount of ore is crushed, the crushed ore after crushing is easily accumulated on the screen, resulting in poor screening effect; for this reason, we have designed a crushing device with a filtering structure. Summary of the Utility Model

[0005] The technical problem solved by the utility model is to provide a crushing device with a filtering structure that has high practicability and can be operated simply and has a relatively simple structure, which solves the problem that when a large amount of ore is crushed, the crushed ore after crushing is easily accumulated on the screen, resulting in poor screening effect as mentioned in the above background art.

[0006] To achieve the above object, the utility model is realized through the following technical solutions: A crushing device with a filtering structure includes a breaking box, a crushing mechanism assembled inside the breaking box, and a filtering mechanism assembled below the breaking box;

[0007] The crushing mechanism includes a servo motor fixedly installed on one side of the crushing box, a first gear fixedly connected to the output end of the servo motor, and a second gear meshing with the first gear. Both sides of the inner wall of the crushing box are penetrated by a first crushing roller and a second crushing roller, and one ends of the first crushing roller and the second crushing roller are respectively fixedly connected to one side of the first gear and the second gear;

[0008] The filtering mechanism includes a fixed cylinder connected to the bottom of the crushing box in a penetrating manner, a spiral blade rotatably connected to one side of the penetrating fixed cylinder, and a first guide wheel fixedly connected to the other side of the second gear. A first belt is sleeved inside the first guide wheel, and a second guide wheel is sleeved on the surface of the first belt. One end of the spiral blade penetrating one side of the fixed cylinder is fixedly connected to one side of the second guide wheel. A filter cylinder is rotatably connected to one end of the fixed cylinder. A third guide wheel is fixedly connected to the surface of the filter cylinder. A second belt is sleeved inside the third guide wheel, and a fourth guide wheel is sleeved on the surface of the second belt. One side of the fourth guide wheel is fixedly connected to the other end of the first crushing roller penetrating the crushing box.

[0009] Optionally, the other end of the spiral blade is rotatably connected to a bracket, and one end of the bracket is fixedly connected to the surface of the fixed cylinder.

[0010] Optionally, a base is fixedly connected to the bottom of the fixed cylinder, and a material guide plate is fixedly connected to one side of the base. The material guide plate is located below the filter cylinder.

[0011] Optionally, the top and bottom of the crushing box are set to be through, and the bottom of the crushing box is connected to the feed port on the surface of the fixed cylinder in a penetrating manner.

[0012] Optionally, a semi-circular plate is arranged on one side of the bracket, and the filter cylinder is rotatably connected to the surface of the semi-circular plate.

[0013] The utility model provides a crushing device with a filtering structure, which has the following beneficial effects:

[0014] The crushing device with a filtering structure, through the settings of the crushing box, the crushing mechanism and the filtering mechanism, turns on the servo motor, which drives the first gear to rotate and then drives the second gear to rotate, causing the first crushing roller and the second crushing roller to rotate. At the same time, the fourth guide wheel at one end of the first gear rotates in the opposite direction to the first guide wheel on one side of the second gear. The spiral blade is driven to rotate in the fixed cylinder by the first belt and the second guide wheel. At the same time, the filter cylinder is driven to rotate in the opposite direction by the second belt and the third guide wheel. Then the ore is introduced between the first crushing roller and the second crushing roller in the crushing box for crushing. The crushed ore falls into the fixed cylinder, and as the spiral blade rotates, the crushed ore is conveyed towards the filter cylinder. When passing through the filter cylinder, the smaller particles of the crushed ore fall from the through holes on the surface of the filter cylinder, while the larger ore is conveyed out from one end of the filter cylinder by the spiral blade, which plays the role of reducing the accumulation and filtration after crushing the ore. At the same time, the opposite rotation of the spiral blade and the filter cylinder can better agitate the crushed ore, making the smaller crushed stones in the crushed ore better filtered out, and improving the screening effect of the ore by this device.

The crushing mechanism 2 includes a servo motor 201 fixedly installed on one side of the crushing box 1 and a first gear 202 fixedly connected to the output end of the servo motor 201, and a second gear 203 meshing with the first gear 202. Both sides of the inner wall of the crushing box 1 are penetrated by a first crushing roller 204 and a second crushing roller 205. One ends of the first crushing roller 204 and the second crushing roller 205 are respectively fixedly connected to one side of the first gear 202 and the second gear 203. The filtering mechanism 3 includes a fixed cylinder 301 connected to the bottom of the crushing box 1 in a penetrating manner and a spiral blade 302 rotatably connected to one side of the fixed cylinder 301 in a penetrating manner, and a first guide wheel 303 fixedly connected to the other side of the second gear 203. A first belt 304 is sleeved inside the first guide wheel 303. A second guide wheel 305 is sleeved on the surface of the first belt 304. One side of the second guide wheel 305 is fixedly connected to one end of the spiral blade 302 penetrating one side of the fixed cylinder 301. One end of the fixed cylinder 301 is rotatably connected to a filter cylinder 306. A third guide wheel 307 is fixedly connected to the surface of the filter cylinder 306. A second belt 308 is sleeved inside the third guide wheel 307. A fourth guide wheel 309 is sleeved on the surface of the second belt 308. One side of the fourth guide wheel 309 is fixedly connected to the other end of the first crushing roller 204 penetrating the crushing box 1. Turn on the servo motor 201 to drive the first gear 202 to rotate and then drive the second gear 203 to rotate, so that the first crushing roller 204 and the second crushing roller 205 rotate. At the same time, the fourth guide wheel 309 at one end of the first gear 202 and the first guide wheel 303 on one side of the second gear 203 rotate in opposite directions. The spiral blade 302 is driven to rotate in the fixed cylinder 301 through the first belt 304 and the second guide wheel 305. At the same time, the filter cylinder 306 is driven to rotate in the opposite direction by the second belt 308 and the third guide wheel 307. Then the ore is introduced between the first crushing roller 204 and the second crushing roller 205 in the crushing box 1 to crush the ore. The crushed ore falls into the fixed cylinder 301. As the spiral blade 302 rotates, the crushed ore is conveyed towards the filter cylinder 306. When passing through the filter cylinder 306, the smaller particles of the crushed ore fall from the through holes on the surface of the filter cylinder 306, while the larger ore is conveyed out from one end of the filter cylinder 306 by the spiral blade 302, which plays a role in reducing the accumulation and filtration after crushing the ore. At the same time, the spiral blade 302 and the filter cylinder 306 rotate in opposite directions, which can better stir the crushed ore and make the smaller crushed stones in the crushed ore better filtered out, improving the screening effect of the ore of this device.

[0023] Furthermore, the other end of the spiral blade 302 is rotatably connected to a bracket 4, and one end of the bracket 4 is fixedly connected to the surface of the fixed cylinder 301. Among them, the bracket 4 can better support the spiral blade 302 and make its rotation smoother.

[0024] Furthermore, a base 5 is fixedly connected to the bottom of the fixed cylinder 301, and a material guiding plate 6 is fixedly connected to one side of the base 5. The material guiding plate 6 is located below the filter cylinder 306. Among them, the material guiding plate 6 can catch the smaller crushed ores filtered out.

[0025] Furthermore, the top and bottom of the crushing box 1 are arranged to be through, and the bottom of the crushing box 1 is connected to the feeding port on the surface of the fixed cylinder 301 in a through manner. Among them, the bottom of the crushing box 1 is in through connection with the fixed cylinder 301, which is convenient for the crushed ores to fall into the fixed cylinder 301.

[0026] Furthermore, a semi-circular plate is arranged on one side of the bracket 4, and the filter cylinder 306 is rotatably connected to the surface of the semi-circular plate. Among them, the semi-circular plate can better support the rotation of the filter cylinder 306.

[0028] The first step: Turn on the servo motor 201 to drive the first gear 202 to rotate, and then drive the second gear 203 to rotate, so that the first crushing roller 204 and the second crushing roller 205 rotate. At the same time, the fourth guide wheel 309 at one end of the first gear 202 rotates in the opposite direction to the first guide wheel 303 on one side of the second gear 203. The spiral blade 302 is driven to rotate in the fixed cylinder 301 through the first belt 304 and the second guide wheel 305. At the same time, the filter cylinder 306 is driven to rotate in the opposite direction by the second belt 308 and the third guide wheel 307;

[0029] The second step: Then import the ores into the middle of the first crushing roller 204 and the second crushing roller 205 in the crushing box 1 to crush the ores. The crushed ores fall into the fixed cylinder 301. As the spiral blade 302 rotates, the crushed ores are conveyed towards the filter cylinder 306. When passing through the filter cylinder 306, the smaller particles of the crushed ores fall from the through holes on the surface of the filter cylinder 306, while the larger ores are conveyed out from one end of the filter cylinder 306 by the spiral blade 302, which plays a role in reducing the accumulation and filtration after crushing the ores. At the same time, the spiral blade 302 and the filter cylinder 306 rotate in the opposite direction, which can better stir the crushed ores and make the smaller crushed stones in the crushed ores be filtered out better.
