A first crushing roller 16 is rotatably arranged on the inner side of the first crushing drum 1, and both ends of the first crushing roller 16 rotate and penetrate the front and rear sides of the first crushing drum 1. A plurality of first positioning drums 1601 are arranged on the surface of the first crushing roller 16, and a first crushing tooth 1602 is installed on one side of the plurality of first positioning drums 1601 by screws, so that a single damaged first crushing tooth 1602 can be replaced conveniently by screws, and the replacement effect can be improved. The crushing parts of the plurality of first crushing teeth 1602 adopt a conical structure, which can increase the contact with the coal-based solid waste. The contact effect is improved, thereby improving the crushing effect. A second crushing roller 17 is rotatably arranged on the inner side of the second crushing drum 2. Both ends of the second crushing roller 17 rotate and penetrate the front and rear sides of the second crushing drum 2. A plurality of second positioning cylinders 1701 are arranged on the surface of the second crushing roller 17. Second crushing teeth 1702 are installed on one side of the plurality of second positioning cylinders 1701 by screws.

A plurality of fixed teeth 21 adopt a pyramid structure, which can improve the shear force with the first crushing tooth 1602 and the second crushing tooth 1702, thereby improving the crushing effect. A driving mechanism 3 for driving the first crushing roller 16 and the second crushing roller 17 to rotate in opposite directions is arranged on the upper side of the first crushing cylinder 1. The driving mechanism 3 includes a first driving gear 301 fixedly sleeved on one end of the first crushing roller 16, and a second driving gear 302 is fixedly sleeved on one end of the second crushing roller 17.

During crushing, the driving motor 303 drives the driving gear 304 to rotate clockwise (in, Figure 3 angle) to rotate, thereby driving the first driving gear 301 counterclockwise (at Figure 3 The first driving gear 301 rotates to drive the first crushing roller 16 to rotate counterclockwise (at Figure 3 angle) to rotate, and at the same time drive the second driving gear 302 clockwise (at Figure 3 The second driving gear 302 drives the second crushing roller 17 to rotate in the opposite direction to the first crushing roller 16, so that the first crushing teeth 1602 on the surface of the first crushing roller 16 and the second crushing teeth 1702 on the surface of the second crushing roller 17 rotate in opposite directions, thereby improving the crushing effect of coal-based solid waste and further improving the crushing efficiency.

[0037] like Figure 5 , Fig.13As shown, a grinding cylinder 14 is integrally arranged at the lower side of the connection between the first crushing cylinder 1 and the second crushing cylinder 2. The grinding cylinder 14 adopts a hollow square structure.

The first reciprocating grinding mechanism 18 includes a first reciprocating plate 1801 vertically slidably arranged on the inner side of the grinding cylinder 14. A plurality of first left grinding plates 1802 are arranged on one side of the first reciprocating plate 1801, and a plurality of first right grinding plates 1803 are arranged on the other side of the first reciprocating plate 1801. The second reciprocating grinding mechanism 19 includes a first reciprocating plate 1801 vertically slidably arranged on the inner side of the grinding cylinder 14.

Since the fixed grinding plates 1401 and the first left grinding plate 1802 and the first right grinding plate 1802 in the same plane During the dislocation grinding process, there will be a certain gap between the second left grinding plate 1903, the second right grinding plate 1902 and the fixed grinding plate 1401, so some of the coal-based solid waste that has not been ground will fall down. When grinding is required, the first reciprocating plate 1801 and the second reciprocating plate 1901 reciprocate vertically in opposite directions, so that the first left grinding plate 1802 on the left side of the first reciprocating plate 1801 and the fixed grinding plate 1401 on the inner side wall of the grinding cylinder 14 are ground together, so that the coal-based solid waste between the left side of the first reciprocating plate 1801 and the inner side wall of the grinding cylinder 14 is ground. The first right grinding plate 1803 on the right side of the first reciprocating plate 1801 and the second left grinding plate 1903 on the left side of the second reciprocating plate 1901 are matched with each other in upper and lower grinding to grind the coal-based solid waste between the right side of the first reciprocating plate 1801 and the left side of the second reciprocating plate 1901. At the same time, the second right grinding plate 1902 on the right side of the second reciprocating plate 1901 is matched with the fixed grinding plate 1401 on the inner wall of the grinding cylinder 14 to grind the coal-based solid waste between the right side of the second reciprocating plate 1901 and the inner wall of the grinding cylinder 14, thereby increasing the grinding space and improving the grinding efficiency.

[0038] like Figure 5 , Fig.13As shown, the distance between the first right grinding plates 1803 and the second left grinding plates 1903 decreases from top to bottom, the distance between the second right grinding plates 1902 and the fixed grinding plates 1401 decreases from top to bottom, and the distance between the first left grinding plates 1802 and the fixed grinding plates 1401 decreases from top to bottom. In this embodiment, the first left grinding plate 1802, the first right grinding plate 1803, the second left grinding plate 1903, the second right grinding plate 1902 and the fixed grinding plate 1401 are respectively arranged in four groups from top to bottom, and the distance between two adjacent grinding plates on the same horizontal plane of the four groups is 3-5mm, 1-3mm, 0.5-1mm, and 0.1-0.5mm from top to bottom, respectively. The specific distance can be flexibly adjusted according to production requirements.

[0039] like Figure 1 , Figure 2 , Figure 7 , Fig. 9 , Fig.13 As shown, the front and rear sides of the grinding cylinder 14 are provided with a first connecting rod mechanism 5 that drives the first reciprocating grinding mechanism 18 to reciprocate up and down. The first connecting rod mechanism 5 includes a first rotating disk 501 fixedly arranged at one end of the first crushing roller 16 and located outside the first crushing cylinder 1. A first eccentric rod 502 is fixedly arranged at an eccentric position of the first rotating disk 501. A first connecting rod 503 is rotatably sleeved on the first eccentric rod 502. A first pull rod 504 fixedly connected to one side of the first reciprocating plate 1801 is rotatably sleeved on the lower end of the first connecting rod 503. The first pull rod 504 is fixedly arranged in the middle of the first reciprocating plate 1801. When in use, the first crushing roller 16 rotates to drive the first rotating disks 501 at both ends thereof to rotate clockwise (in Figure 2 , Figure 7 angle) to rotate, thereby causing the first eccentric rod 502 on the first rotating disk 501 to rotate clockwise (at Figure 2 , Figure 7 The first connecting rod 503 is rotated by a rotation angle to drive the first connecting rod 503 to reciprocate up and down, thereby pulling the first pull rod 504 at the lower end of the first connecting rod 503 to reciprocate up and down, so that the first reciprocating plate 1801 at one end of the first pull rod 504 can be reciprocated up and down, driving the first left grinding plate 1802 and the first right grinding plate 1803 on both sides of the first reciprocating plate 1801 to reciprocate up and down, so that the coal-based solid waste that has been initially crushed and fallen into the grinding cylinder 14 can be ground.

[0040] like Figure 1 , Figure 2 , Figure 8 , Fig. 9 , Fig.13As shown, the front and rear sides of the grinding cylinder 14 are provided with a second connecting rod mechanism 6 that drives the second reciprocating grinding mechanism 19 to reciprocate up and down. The second connecting rod mechanism 6 includes a second rotating disk 601 that is fixedly arranged at one end of the second crushing roller 17 and located outside the second crushing cylinder 2. A second eccentric rod 602 is fixedly arranged at the eccentric position of the second rotating disk 601. A second connecting rod 603 is rotatably sleeved on the second eccentric rod 602. A second pull rod 604 that is fixedly connected to one side of the second reciprocating plate 1901 is rotatably sleeved on the lower end of the second connecting rod 603. When in use, the second crushing roller 17 rotates to drive the second rotating disks 601 at both ends thereof to rotate counterclockwise (in Figure 2 , Figure 8 angle) to rotate, thereby causing the second eccentric rod 602 on the second rotating disk 601 to rotate counterclockwise (at Figure 2 , Figure 8 The second reciprocating plate 1901 at one end of the second pull rod 604 can make a reciprocating motion up and down, and drive the second left grinding plate 1903 and the second right grinding plate 1902 on both sides of the second reciprocating plate 1901 to reciprocate up and down, so that the coal-based solid waste that has been initially crushed and fallen into the grinding cylinder 14 can be ground. When the first reciprocating plate 1801 moves upward, the second reciprocating plate 1901 moves downward at this time. During the reciprocating grinding process, the first reciprocating plate 1801 and the second reciprocating plate 1901 will not be completely staggered, so that the grinding area of ​​the coal-based solid waste that has been initially crushed between the first reciprocating plate 1801 and the second reciprocating plate 1901 can be increased, thereby improving the grinding efficiency.

When the first reciprocating plate 1801 and the second reciprocating plate 1901 slide back and forth up and down, the particle powder inside the grinding cylinder 14 can be prevented from leaking from the limit grooves 22. The outer sides of the first pull rod 504 and the second pull rod 604 are rotatably sleeved with limit blocks 23 respectively slidably connected to the two limit grooves 22. By sleeved with the limit blocks 23 respectively The limit block 23 on the first pull rod 504 and the second pull rod 604 can slide up and down in the limit groove 22 when the first pull rod 504 and the second pull rod 604 reciprocate up and down, so as to limit the first pull rod 504 and the second pull rod 604 so that the first pull rod 504 and the second pull rod 604 can slide vertically, thereby preventing the first pull rod 504 and the second pull rod 604 from shifting and affecting the grinding effect of the first reciprocating plate 1801 and the second reciprocating plate 1901.

The coal-based solid waste after being ground inside the grinding cylinder 14 will fall into the inside of the unloading cylinder 2001, and because the distance between the lowest group of grinding plates inside the grinding cylinder 14 is 0.1-0.5mm, and because the grinding plates of the same group of grinding plates will not be completely staggered during the process of offset grinding, the particle size of the coal-based solid waste flowing out of the lowest group of grinding plates is less than 0.5mm, and the lower ends of the first reciprocating plate 1801 and the second reciprocating plate 1901 are both connected by screws with a sealing unloading plate 2002 that slides through the lower end of the unloading cylinder 2001, and both sides of the two unloading plates 2002 are provided with unloading grooves 2003. When the coal-based solid in the grinding cylinder 14 After the waste is ground, the ground powder will fall into the interior of the discharge barrel 2001. When the first reciprocating plate 1801 and the second reciprocating plate 1901 reciprocate up and down, the discharge plate 2002 at the lower end thereof will be driven to reciprocate up and down through the lower end of the discharge barrel 2001. Since discharge troughs 2003 are provided on both sides of the discharge plate 2002, when the discharge plate 2002 rises (i.e. slides into the interior of the discharge barrel 2001), the coal-based solid waste powder inside the discharge barrel 2001 will slide into the interior of the discharge trough 2003. When the discharge plate 2002 falls (i.e. slides out from the bottom of the discharge barrel 2001), the discharge troughs 2003 on both sides of the discharge plate 2002 can drive the coal-based solid waste powder inside it to slide out of the discharge barrel 2001, and the volume of each discharge is consistent, which is convenient for the subsequent separation of powders of different particle sizes, improves the separation effect, and prevents excessive volume from falling at one time, affecting the separation effect.

[0044] like Figure 5 , Figure 6 , Fig.14As shown, a first blowing mechanism 8 and a second blowing mechanism 9 are provided on one side of the separation box 7. Since only two blowing mechanisms are shown in this embodiment, the number of specific blowing mechanisms can be flexibly set according to process requirements, and coal-based solid wastes of different particle sizes can be obtained. The second blowing mechanism 9 is located below the first blowing mechanism 8. The first blowing mechanism 8 and the second blowing mechanism 9 both include a mounting plate 801 fixedly arranged on one side of the separation box 7. A plurality of air outlet pipes 804 for blowing air horizontally toward the inside of the separation box 7 are provided on the two mounting plates 801. The plurality of air outlet pipes 804 are arranged horizontally in multiple rows, which can be In order to increase the blowing range and improve the separation effect, in actual use, the outlet direction of the multiple air outlet pipes 804 can also be tilted upward to improve the contact effect between the gas and the powder, thereby improving the separation effect. The other end of the multiple air outlet pipes 804 is connected to the collecting pipe 802, and one end of the collecting pipe 802 is connected to the air inlet pipe 803. One end of the air inlet pipe 803 is connected to an air pump (not shown in the figure). The air pump can adjust the flow rate of the gas, wherein the flow rate of the air pump in the first blowing mechanism 8 is less than the flow rate of the air pump in the second blowing mechanism 9, for example, the flow rate of the air pump in the first blowing mechanism 8 is less than the flow rate of the air pump in the second blowing mechanism 9. The flow rate of the air pump is 1.2-1.6 m / s, and the flow rate of the air pump in the second blowing mechanism 9 is 1.6-2.8 m / s. The specific flow rate can be flexibly adjusted according to demand. When in use, when the powder inside the lower barrel 2001 falls, the powder is first blown through the air outlet pipe 804 in the first blowing mechanism 8. At this time, the blowing wind speed is 1.2-1.6 m / s, so that the smaller powder below 0.5 mm is blown into the first feed port 1202, and then discharged through the first discharge port 1201 at the lower end of the first discharge barrel 12 on one side of the first feed port 1202. During the discharge process, since the filter screen 1302 is arranged on one side of the first discharge barrel 12, the powder cannot pass through the filter screen 1302 on the first discharge barrel 12, so that the gas blown into the first discharge barrel 12 can be discharged from the filter screen 1302, so that the powder is filtered by the filter screen 1302, and the powder is discharged from the first discharge port 1201. When the powder in the separation box 7 continues to fall, the powder passes through one side of the second blowing mechanism 9, so that the powder is blown by the air outlet pipe 804 in the second blowing mechanism 9. At this time, the wind speed of the blowing is 1.6-2.8m / s, so that 0.The larger particles below 5 mm are blown into the second feed port 1102, and then discharged through the second discharge port 1101 at the lower end of the second discharge barrel 11 on the side of the second feed port 1102. During the discharge process, since the filter screen 1302 is set on one side of the second discharge barrel 11, the powder cannot pass through the filter screen 1302 on the second discharge barrel 11, so that the gas blown into the second discharge barrel 11 can be discharged from the filter screen 1302, so that the powder is filtered by the filter screen 1302, and the powder is discharged from the second discharge port 1101 by gravity, and the remaining particles will be discharged from the third discharge barrel 10 at the bottom of the separation box 7, so that coal-based solid wastes of different particle sizes can be separated, and the separation effect can be improved, and different particle sizes will not be mixed together. .

[0045] A bag opener and a quantitative feeder (not shown in the figure) can be set on one side of the feed hopper 4 for coal-based solid waste, and the bag opener is set at the front end of the quantitative feeder, and the output end of the quantitative feeder cooperates with the feed hopper 4. The bag opener disperses the coal-based solid waste through rolling gear, and the quantitative feeder can continuously weigh and feed the coal-based solid waste, so that the coal-based solid waste entering the feed hopper 4 is continuously weighed, measured and quantitatively controlled. The coal-based solid waste particles discharged from the first discharge port 1201, the second discharge port 1101 and the third discharge port 1001 can be dedusted by cyclone dust collectors (not shown in the figure) respectively. The cyclone dust collector can separate the tiny dust in the coal-based solid waste particles, so as to facilitate the subsequent production of better quality glass fiber elastic felt through the coal-based solid waste particles.

[0046] It should be noted that, when in use, the crushing and breaking device for producing glass fiber elastic felt transports the coal-based solid waste to the feed hopper 4 through the quantitative feeder, and pours the coal-based solid waste into the first crushing drum 1 and the second crushing drum 2 through the feed hopper 4, and then drives the driving gear 304 to rotate through the driving motor 303, thereby driving the first driving gear 301 to rotate. The rotation of the first driving gear 301 drives the first crushing roller 16 to rotate, and at the same time drives the second driving gear 302 to rotate. The second driving gear 302 drives the second crushing roller 17 to rotate in the opposite direction to the first crushing roller 16, so that the first crushing teeth 1602 on the surface of the first crushing roller 16 and the second crushing teeth 1702 on the surface of the second crushing roller 17 rotate in opposite directions. , so that the coal-based solid waste inside the first crushing drum 1 and the second crushing drum 2 is preliminarily crushed and scattered, and then the preliminarily crushed and scattered coal-based solid waste falls into the grinding drum 14, at this time, the first crushing roller 16 rotates to drive the first turntable 501 at both ends thereof to rotate clockwise, thereby making the first eccentric rod 502 on the first turntable 501 rotate clockwise, driving the first connecting rod 503 to reciprocate up and down, and then pulling the first pull rod 504 at the lower end of the first connecting rod 503 to reciprocate up and down, so that the first reciprocating plate 1801 at one end of the first pull rod 504 can reciprocate up and down, driving the first left grinding plate 1802 and the first right grinding plate 1803 on both sides of the first reciprocating plate 1801 to reciprocate up and down, and at the same time, the second crushing roller 16 rotates to drive the first turntable 501 at both ends thereof to rotate clockwise, thereby driving the first eccentric rod 502 on the first turntable 501 to rotate clockwise, driving the first connecting rod 503 to reciprocate up and down, and then pulling the first pull rod 504 at the lower end of the first connecting rod 503 to reciprocate up and down, and then the first reciprocating plate 1801 at one end of the first pull rod 504 to reciprocate up and down, and driving the first left grinding plate 1802 and the first right grinding plate 1803 on both sides of the first reciprocating plate 1801 to reciprocate up and down, and at the same time The rotation of the roller 17 drives the second rotating disk 601 at both ends thereof to rotate counterclockwise, thereby causing the second eccentric rod 602 on the second rotating disk 601 to rotate counterclockwise, driving the second connecting rod 603 to reciprocate up and down, thereby pulling the second pull rod 604 at the lower end of the second connecting rod 603 to reciprocate up and down, which can make the second reciprocating plate 1901 at one end of the second pull rod 604 to reciprocate up and down, driving the second left grinding plate 1903 and the second right grinding plate 1902 on both sides of the second reciprocating plate 1901 to reciprocate up and down, which can make the first reciprocating plate 1801 and the second reciprocating plate 1901 reciprocate vertically in opposite directions inside the grinding cylinder 14, through the first left grinding plate 1802 and the first right grinding plate 1902 on both sides of the first reciprocating plate 1801. The second left grinding plate 1903 and the second right grinding plate 1902 on both sides of the grinding plate 1803 and the second reciprocating plate 1901 slide alternately with each other, so that the coal-based solid waste that has been preliminarily crushed inside the grinding cylinder 14 is ground, and the ground coal-based solid waste falls into the interior of the discharge barrel 2001. When the first reciprocating plate 1801 and the second reciprocating plate 1901 reciprocate up and down, the discharge plate 2002 at its lower end will be driven to reciprocate up and down through the lower end of the discharge barrel 2001. Since discharge troughs 2003 are provided on both sides of the discharge plate 2002, when the discharge plate 2002 rises (that is, slides into the interior of the discharge barrel 2001), the coal-based solid waste powder inside the discharge barrel 2001 will slide into the interior of the discharge trough 2003.When the lower feeding plate 2002 descends (i.e., slides out from the bottom of the lower feeding barrel 2001), the feeding troughs 2003 on both sides of the lower feeding plate 2002 can drive the coal-based solid waste powder inside it to slide out of the lower feeding barrel 2001, and the volume of each discharge is consistent. When the powder inside the lower feeding barrel 2001 falls, the powder is first blown through the air outlet pipe 804 in the first blowing mechanism 8. At this time, the blowing wind speed is 1.2-1.6m / s, so that part of the powder is blown into the first feeding port 1202, and then discharged through the first discharge port 1201 at the lower end of the first discharge barrel 12 on one side of the first feeding port 1202. During the discharge process, since a filter screen 1302 is provided on one side of the first discharge barrel 12, the gas blown into the first discharge barrel 12 can be discharged from the filter screen 1302, so that the powder is filtered by the filter screen 1302, and then discharged from the first discharge barrel 12. The powder is discharged from a discharge port 1201. When the powder inside the separation box 7 continues to fall, the powder passes through one side of the second blowing mechanism 9, so that the powder is blown by the air outlet pipe 804 in the second blowing mechanism 9. At this time, the blowing wind speed is 1.6-2.8m / s, so that some particles are blown into the second feed port 1102, and then discharged through the second discharge port 1101 at the lower end of the second discharge barrel 11 on the side of the second feed port 1102. In the process of discharge, since a filter screen 1302 is set on one side of the second discharge barrel 11, the gas blown into the second discharge barrel 11 can be discharged from the filter screen 1302, so that the powder is filtered by the filter screen 1302 and then discharged from the second discharge port 1101. The remaining particles will be discharged from the third discharge barrel 10 at the bottom of the separation box 7, so that coal-based solid wastes of different particle sizes can be separated.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
