Description

Technical Field

[0001] The present invention relates to the field of coal preparation, and particularly to a multifunctional coal preparation device. Background Art

[0002] During the coal mining process, the raw coal obtained often contains a large amount of gangue. In order to effectively separate these impurities, coal preparation technologies have emerged, mainly including gravity coal preparation, flotation coal preparation, and hand selection, etc. Hand selection is a process of meticulous screening by hand based on the differences in color, luster, and appearance between lump coal and gangue.

[0003] During the coal preparation process of the coal preparation device, when using a conveyor belt to transport raw coal, the coal is prone to accumulation at the feeding port. As a result, during the coal preparation process of the device, only the upper half of the accumulated coal can be sorted, but the lower half of the accumulated coal cannot be effectively sorted. Thus, some gangue and other impurities are still mixed in the coal that has been sorted, resulting in low working efficiency of the device and poor sorting effect of the coal.

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Example

[0019] A multifunctional coal preparation equipment, such as Figures 1-6As shown in the figure, it includes a feeding box 1. Inside the upper side of the feeding box 1, there is a dispersion mechanism 2 for evenly dispersing the raw coal material. The dispersion mechanism 2 includes a fixing plate 201. The fixing plate 201 is fixedly connected to the upper side inside the feeding box 1. A rectangular cavity is opened inside the fixing plate 201. At the bottom of the cavity opened inside the fixing plate 201, there is a second spring 203 fixedly connected. The other end of the second spring 203 is fixedly connected to a trigger sliding rod 202. The front end of the trigger sliding rod 202 is set as an inclined plate. The trigger sliding rod 202 increases the contact time with the cam 308 when the feeding box 1 vibrates up and down through the inclined plate. The trigger sliding rod 202 is slidably connected to the cavity opened inside the fixing plate 201. A rectangular through hole is opened in the middle inside the trigger sliding rod 202. On one side of the through hole opened in the middle inside the trigger sliding rod 202, there are teeth. The trigger sliding rod 202 is meshed and connected to a gear column 205 through the teeth. Inside the gear column 205, there is a rotating column 204 fixedly connected. Through holes are opened on the upper and lower sides of the fixing plate 201. Rectangular sliding grooves communicating with the cavity inside the fixing plate 201 are opened on the left and right sides of the fixing plate 201. The rotating column 204 is rotatably connected to the through holes opened on the upper and lower sides of the fixing plate 201. On the outer sides of the upper and lower ends of the rotating column 204, there are rotating rods 206 fixedly connected. The rotating rods 206 are slidably connected to the rectangular sliding grooves opened on the left and right sides of the fixing plate 201 and communicating with the cavity inside the fixing plate 201. The two rotating rods 206 are parallel to each other. Inside the other end of the rotating rod 206, there is a limiting column 207 fixedly connected. When the cam 308 rotates, the cam 308 pushes the trigger sliding rod 202 inward through the protrusion and compresses the second spring 203. The trigger sliding rod 202 drives the gear column 205 to rotate clockwise through the teeth. The gear column 205 drives the rotating rods 206 at both ends to rotate clockwise through the rotating column 204. The rotating rod 206 pushes the sliding push block 208 outward through the limiting column 207. When the protrusion of the cam 308 passes through the trigger sliding rod 202, the second spring 202 releases the elastic potential energy and pushes the trigger sliding rod 202 to reset outward. The trigger sliding rod 202 drives the gear column 205 to rotate counterclockwise through the teeth. The gear column 205 drives the rotating rods 206 at both ends to rotate counterclockwise through the rotating column 204. The rotating rod 206 pulls the sliding push block 208 inward through the limiting column 207. Repeating like this, the rotating rod 206 reciprocally pushes the sliding push block 208 to move through the limiting column 207.

[0020] As Figures 3-5As shown, sliding push blocks 208 are provided at the outer ends of the two rotating rods 206. A chute is formed inside the sliding push block 208. The rotating column 204 is slidably connected to the chute formed inside the sliding push block 208. Limit grooves are formed on the upper and lower sides of the chute formed inside the sliding push block 208. The limit posts 207 are slidably connected to the limit grooves formed inside the sliding push block 208. Rectangular limit sliders are fixedly connected to both ends of the sliding push block 208. The sliding push block 208 is slidably connected to the limit support frame 209 through the limit sliders. The outer end of the limit support frame 209 is fixedly connected to the feed box 1, and the other end of the limit support frame 209 is fixedly connected to the fixed plate 201. A L-shaped rod 210 is fixedly connected to the middle of the lower end of the sliding push block 208. Three connecting plates 211 are fixedly connected to the lower end of the L-shaped rod 210. Three stirring rods 212 for uniformly stirring the raw coal are fixedly connected to the lower end of the connecting plate 211. When the two sliding push blocks 208 move left and right reciprocally, the sliding push block 208 drives the connecting plate 211 to move left and right reciprocally through the L-shaped rod 210, and the connecting plate 211 drives the stirring rod 212 to stir the raw coal left and right reciprocally and uniformly.

[0021] As Figure 1 , Figure 2 shown, a feed inlet for the raw coal is formed at the upper end of the feed box 1. Four rectangular fixing blocks 101 are respectively fixedly connected to both sides of the feed box 1. A sliding column 102 is fixedly connected to the lower end of the fixing block 101. The two sliding columns 102 on the right side are shorter than the two sliding columns 102 on the left side. A first spring 103 is fixedly connected to the lower end of the sliding column 102. A rectangular vertical support rod 104 is sleeved outside the sliding column 102. The two rectangular vertical support rods 104 on the right side are shorter than the two rectangular vertical support rods 104 on the left side. A hole is formed at the upper end of the vertical support rod 104. The sliding column 102 is slidably connected to the hole formed at the upper end of the vertical support rod 104. The lower end of the first spring 103 is fixedly connected to the vertical support rod 104. A support plate 105 is fixedly connected to the lower end of the vertical support rod 104. When the cam 308 rotates, the cam 308 pushes the contact block 106 upward through the protrusion. The contact block 106 drives the feed box 1 to move upward. The feed box 1 drives the sliding column 102 to pull the first spring 103 upward through the fixing block 101. When the cam 308 passes through the contact block 106, the first spring 103 releases its elastic potential energy and pulls the sliding column 102 downward. The sliding column 102 pulls the feed box 1 downward through the fixing block 101, realizing the vibration of the feed box 1. In this way, the feed box 1 vibrates up and down reciprocally, sifting the raw coal through the filter plate 107, and at the same time accelerating the downward movement of the raw coal.

[0022] As Figure 2 shown, a filter plate 107 for filtering the raw coal is fixedly connected inside the feed box 1. The right end of the filter plate 107 is located above the conveyor belt. A discharge port is formed on the right side of the feed box 1. Two contact blocks 106 are fixedly connected to the upper right side of the feed box 1.

[0023] AsFigure 7 As shown in the figure, a conveying mechanism 3 for conveying raw coal is provided on the right side of the feeding box 1. The conveying mechanism 3 includes a box body 301. A plurality of through holes are opened on both sides of the box body 301. A rectangular support plate 309 is fixedly connected to the right side of the box body 301. The upper end of the support plate 309 is fixedly connected to a motor 302 through a support. The output end of the motor 302 is fixedly connected to an output shaft 305. A pulley 304 is fixedly connected to the outside of the output shaft 305. The output shaft 305 is rotatably connected in the through holes opened on both sides of the box body 301. The output shaft 305 extends to the left side of the box body 301, and the left end of the output shaft 305 is fixedly connected to another pulley 304. A transmission shaft 306 is rotatably connected in the through holes opened on both sides of the box body 301. A pulley 304 is fixedly connected to the right end of the transmission shaft 306 at the right end of the box body 301. A belt is sleeved between the pulley 304 at the right end of the transmission shaft 306 and the pulley 304 on the outside of the output shaft 305. A conveyor belt 310 for transporting raw coal is sleeved on the outside of the transmission shaft 306 and the output shaft 305. A protective shell 303 for preventing the belt from being exposed to the outside is provided on the outside of the belt. The side of the protective shell 303 is fixedly connected to the box body 301. The protective shell 303 is provided with a through hole. The output shaft 305 is rotatably connected in the through hole opened in the protective shell 303.

[0024] As Figure 7 、 Figure 8 shown in the figure, a rotating shaft 307 is rotatably connected in the through hole on the upper side of the left end of the box body 301. The rotating shaft 307 extends to the outside of the left end of the box body 301, and the left end of the rotating shaft 307 is fixedly connected to a pulley 304. A belt is sleeved between the pulley 304 at the left end of the rotating shaft 307 and the pulley 304 at the left end of the output shaft 305. Three cams 308 are fixedly connected to the middle of the rotating shaft 307. The cams 308 at both ends are respectively abutted against the contact blocks 106, and the middle cam 308 is abutted against the inclined surface of the trigger slide bar 202.

[0025] As Figure 7 shown in the figure, a through hole is opened on the upper end of the box body 301. A dust removal mechanism 4 is fixedly connected in the through hole opened on the upper end of the box body 301. The dust removal mechanism 4 cleans the dust generated during transportation to prevent the dust from polluting the working environment.

[0026] As Figure 1 、 Figure 9 shown in the figure, a separation mechanism 5 for separating and removing gangue is provided on the right end of the box body 301. The separation mechanism 5 includes a separation box 501. The separation box 501 is fixedly connected to the box body 301. A partition 502 is fixedly connected inside the separation box 501. The partition 502 divides the separation box 501 into two compartments. A laser observation device 503 for identifying gangue is fixedly connected to the upper side inside the right end of the box body 301. A separation device 505 for jetting and separating gangue is fixedly connected to the lower side inside the right end of the box body 301. The separation device 505 is connected to a control device 504 through a pipeline.

[0027] As Figure 1 、 Figure 10 shown, a through hole is provided on the lower side of the left end of the feeding box 1, and a sealing mechanism 6 for sealing the bottom of the feeding box 1 is provided in the through hole provided on the lower side of the left end of the feeding box 1. The sealing mechanism 6 includes a sealing door 601. The left end of the sealing door 601 is rotatably connected to the feeding box 1 through a rotating shaft. A limiting block 602 is fixedly connected to the right end of the outer side of the sealing door 601. A rectangular sliding groove is provided inside the limiting block 602. A through hole communicating with the sliding groove provided inside the limiting block 602 is provided on the side surface of the limiting block 602. A third spring 603 is fixedly connected to the bottom of the sliding groove provided inside the limiting block 602. The other end of the third spring 603 is fixedly connected to a wedge block 604. The inner side of the upper end of the wedge block 604 is an inclined surface. The wedge block 604 is slidably connected in the sliding groove provided inside the limiting block 602. A push rod 605 is fixedly connected to the side surface of the wedge block 604. The push rod 605 is slidably connected in the through hole provided on the side surface of the limiting block 602. A U-shaped frame 606 is slidably connected to the outer side of the upper end of the wedge block 604. The inner side of the U-shaped frame 606 is fixedly connected to the feeding box 1. When the push rod 605 is pushed downward, the push rod 605 compresses the third spring 603 downward through the wedge block 604. At this time, the U-shaped frame 606 loses the limit on the wedge block 604, and further, the sealing door 601 can be opened, and the inside of the feeding box 1 can be cleaned. When closing, the U-shaped frame 606 pushes the wedge block 604 downward through the inclined surface. The wedge block 604 compresses the third spring 603 downward. When the wedge block 604 enters the U-shaped frame 606, the third spring 603 releases its elastic potential energy and pushes the wedge block 604 upward, and the U-shaped frame 606 re-limits the wedge block 604.

[0028] As Figure 1 shown, a first bracket 7 is fixedly connected to the lower end of the support plate 105, and a second bracket 701 is fixedly connected to the lower end of the box body 301. The second bracket 701 is fixedly connected to the control device 504 through a support rod.

[0029] Working principle: start the motor 302 and the control device 504 respectively, and transport the raw coal into the feed box 1. The motor 302 drives the pulleys 304 at both ends to rotate through the output shaft 305. The pulley 304 at the left end rotates and drives the pulley 304 at the end of the transmission shaft 306 to rotate through the belt. The transmission shaft 306 and the output shaft 305 cooperate with each other to drive the outer conveyor belt 310 to rotate. The conveyor belt 310 transports the raw coal to the right. At the same time, the pulley 304 at the left end of the output shaft 305 drives the pulley 304 at the left end of the rotating shaft 307 to rotate through the belt. The pulley 304 drives the cam 308 to rotate through the rotating shaft 307. The cams at both ends of the rotating shaft 307 308 rotates through the contact block 106 to drive the feed box 1 to move upward, and the feed box 1 drives the sliding column 102 to move upward through the fixed blocks 101 around it, and the sliding column 102 stretches the spring 103 upward. When the cam 308 drives the feed box 1 to reach the highest point through the contact block 106, the spring 103 releases the pulling force downward, and the spring 103 drives the sliding column 102 to pull the feed box 1 downward through the fixed block 101, and the feed box 1 moves back and forth like this. The feed box 1 drives the filter plate 107 to vibrate and clean the particles and dust on the surface of the raw coal. The cleaned particles and dust fall downward into the bottom of the feed box 1, and the raw coal is accelerated to enter the box body 301 through vibration and the inclined surface of the filter plate 107.

[0030] At the same time, when the rotating shaft 307 rotates, the cam 308 in the middle of the rotating shaft 307 pushes the trigger slide bar 202 to the right through the side, and the trigger slide bar 202 compresses the spring 203 inward. At the same time, the trigger slide bar 202 drives the gear column 205 to rotate clockwise through the teeth, and the gear column 205 drives the rotating rods 206 on the upper and lower sides to rotate clockwise through the rotating column 204. The rotating rod 206 pushes the sliding push block 208 outward through the limit column 207 at the end. The sliding push block 208 drives the connecting plate 211 to move outward through the L support rod 210, and the connecting plate 211 drives the toggle rod 212 to toggle the raw coal. When the cam 308 in the middle of the rotating shaft 307 After the trigger slide bar 202 is passed, the spring 203 releases its elastic potential energy to push the trigger slide bar 202 outwards, and the trigger slide bar 202 drives the gear column 205 to rotate counterclockwise through the teeth, and the gear column 205 drives the rotating rods 206 on the upper and lower sides to rotate counterclockwise through the rotating column 204, and the rotating rod 206 pulls the sliding push block 208 inward through the limit column 207 at the end, and the sliding push block 208 drives the connecting plate 211 to move inward through the L support rod 210, and the connecting plate 211 drives the toggle rod 212 to toggle the raw coal, and the reciprocating motion is repeated, and the toggle rod 212 to toggle the raw coal at the feed inlet, so that the raw coal is evenly distributed on the conveyor belt.

[0031] When the raw coal material is conveyed to the right end of the conveyor belt 310, the laser observation device 503 identifies the gangue in the raw coal material. Further, the laser observation device 503 sends the information to the control device 504, and the control device 504 jets air at the gangue through the control of the separation device 505, so that the gangue flies upward to the right side of the partition plate 502, and the coal material further falls downward to the left side of the partition plate 502. The separated coal material and gangue enter the next process through conveying.

[0032] When the dust and particles inside the feed box 1 need to be cleaned, pull down the push rod 605. The push rod 605 compresses the third spring 603 downward through the wedge block 604, and the U-shaped frame 606 loses the limit on the wedge block 604. Further, pull the push rod 605 outward. The push rod 605 drives the sealing door 601 to rotate counterclockwise through the limit block 602. After opening the lower side of the feed box 1, release the push rod 605. The third spring 603 releases the elastic potential energy and pushes the wedge block 604 to reset for cleaning the inside. After the cleaning is completed, push the push rod 605 inward. The push rod 605 drives the sealing door 601 to rotate clockwise through the limit block 602. When the inclined surface of the wedge block 604 touches the lower end of the U-shaped frame 606, the wedge block 604 is pushed downward through the inclined surface. The wedge block 604 compresses the third spring 603 downward. After the wedge block 604 enters the U-shaped frame 606, the third spring 603 releases the elastic potential energy and pushes the wedge block 604 upward, so that the U-shaped frame 606 re-limits the wedge block 604.
