Description

Technical Field

[0001] The invention relates to the technical field of double-roll crushing, in particular to a double-roll crusher combined with gas drying and a crushing method thereof. Background Art

[0002] In industrial production, the double roll crusher is favored for its efficient crushing capacity and wide range of applications.

[0003] In the crushing process of the roller crusher, two rollers rotating relative to each other crush the materials through the extrusion force. When the material contains a high moisture content, its viscosity increases and the friction between the materials decreases, which makes it difficult for the material to slide on the roller surface, thus easily causing blockage. In addition, wet materials are easy to adhere in the crushing chamber, forming large lumps, which further aggravates the blockage.

[0004] In this regard, the wet material is properly dried or pre-dried before crushing to reduce the moisture content of the material, thereby reducing its stickiness and the possibility of clogging. However, the existing drying is usually just a simple sun drying or drying of the material surface. Since the material with high humidity may agglomerate, the inside of the material cannot be dried. During the crushing process, it may still stick to the surface of the crushing roller and cause clogging. Summary of the invention

When the materials are dried, before the materials are crushed, the materials can be added into the hopper and dry gas can be transported therein. At the same time, under the action of the drying tumbling component, the materials are stirred by the first mixing blade to increase the contact area between the materials and the gas, so that the drying rate is increased. The drying tumbling component also drives the agglomeration crushing mechanism to crush the materials agglomerated due to excessive humidity through the crushing plate and the first mixing blade. After the drying and crushing is completed, the materials can be transported to the protective box through the conveying pipe. At this time, under the action of the roller crushing mechanism, the dried materials are crushed. If it is necessary to adjust the crushed particle size of the material, under the action of the particle size control mechanism, the distance between the first crushing roller and the second crushing roller is changed, thereby achieving the effect of adjusting the crushed particle size of the material.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0030] See also Figure 1 to Figure 10In an embodiment of the present invention, a double-roll crusher combined with gas drying includes: a support platform 1, a protective box 2, a feed hopper 3, a conveying pipe 4, a drying tumbling assembly, a first mixing blade 7, a clustering and crushing mechanism, a crushing plate 10, a roller crushing mechanism, a first crushing roller 18, a second crushing roller 22, and a particle size control mechanism. If the humidity of the material is too high, its viscosity increases, and the friction between the materials decreases, resulting in the material not being easy to slide on the roller surface, which is easy to cause blockage. In addition, wet materials are easy to adhere in the crushing chamber to form larger lumps, which further aggravates the blockage. Therefore, the materials need to be dried. When crushing the materials, the materials can be added into the hopper 3 and dry gas can be transported into it. At the same time, under the action of the drying tumbling component, the materials are stirred by the first mixing blade 7 to increase the contact area between the material and the gas, so that the drying rate is increased. The drying tumbling component will also drive the agglomeration crushing mechanism to crush the materials agglomerated due to excessive humidity through the crushing plate 10 and the first mixing blade 7. After the drying and crushing is completed, the materials can be transported to the protective box 2 through the conveying pipe 4. At this time, under the action of the roller crushing mechanism, the dried materials are crushed. If it is necessary to adjust the crushed particle size of the material, under the action of the particle size control mechanism, the distance between the first crushing roller 18 and the second crushing roller 22 is changed, thereby achieving the effect of adjusting the crushed particle size of the material.

[0031] The details are as follows, including: A support platform 1, and a protection box 2 installed on the support platform 1, wherein a feed hopper 3 is provided on the protection box 2, and a conveying pipe 4 connected to the protection box 2 is provided at the bottom of the feed hopper 3; Also includes: See also Figure 1 , Figure 2 , Figure 5 , Figure 6 , Fig. 9 , Fig.10 , a drying tumbling assembly is arranged in the feed hopper 3, and a plurality of first mixing blades 7 equidistantly distributed in a circumference are connected to the drying tumbling assembly. The drying tumbling assembly includes a conveying trough 301 opened at the bottom of the feed hopper 3 and connected to the conveying pipe 4. A driving motor 5 is arranged on the side wall of the feed hopper 3. A transmission rod 6 connected to the output shaft of the driving motor 5 is rotatably installed in the feed hopper 3, and the transmission rod 6 is connected to the first mixing blades 7.

[0032] Specifically, during the crushing process of the double-roll crusher, two relatively rotating rollers crush the material through extrusion force. When the material contains a high moisture content, its viscosity increases, and the friction between the materials decreases, making it difficult for the material to slide on the roller surface, which can easily cause blockage. In addition, wet materials are easy to adhere in the crushing chamber to form larger lumps, which further aggravates the blockage. Therefore, it is necessary to dry the wet materials before crushing. The materials can be added into the feed hopper 3, and dry gas can be added into the feed hopper 3. At the same time, the driving motor 5 works and drives the transmission rod 6 to rotate, thereby driving the first mixing blade 7 to rotate. Under the action of the first mixing blade 7, the material can be stirred to increase the contact range between the gas and the material, thereby accelerating the drying rate of the material. At the same time, due to the excessive humidity of the material, it may cause adhesion to the conveying trough 301, resulting in the clogging of the conveying trough 301. Therefore, under the action of the first mixing blade 7, the wet materials adhered to the feed hopper 3 are scraped off, and the transmission rod 6 will also drive the agglomeration crushing mechanism to move, so as to crush the agglomerated materials through the crushing plate 10 and the first mixing blade 7 to ensure that the materials are crushed after drying.

[0033] See also Figure 1 , Figure 2 , Figure 5-Figure 10 , a clumping and crushing mechanism is arranged in the feeding hopper 3 and connected to the drying tumbling assembly, a crushing plate 10 is connected to the clumping and crushing mechanism, and the clumping and crushing mechanism can be actuated when the drying tumbling assembly moves, so as to crush the clumped materials by adjusting the distance between the crushing plate 10 and the first mixing blade 7, and the clumping and crushing mechanism includes a movable sleeve 8 slidably mounted on the transmission rod 6, and a plurality of second mixing blades 9 equidistantly distributed on the circumference are arranged on the movable sleeve 8, and the second mixing blades 9 are connected to the crushing plate 10, and a follower assembly connected to the movable sleeve 8 is arranged in the feeding hopper 3, wherein The follower assembly includes a fixed sleeve 12 installed on the inner wall of the feed hopper 3, and a plurality of annular grooves 1201 equidistantly distributed in a circumference are provided on the fixed sleeve 12; it also includes a support plate 13 installed on the movable sleeve 8, and a protrusion 1301 slidably connected to the annular groove 1201 is provided on the support plate 13, and a guide structure connected to the transmission rod 6 is provided on the movable sleeve 8. The guide structure mentioned above includes a spiral groove 601 and a transverse groove 602 provided on the transmission rod 6, and a limit block 11 slidably connected to the spiral groove 601 and the transverse groove 602 is provided on the inner wall of the movable sleeve 8.

[0034] It should be noted that, since the material may agglomerate during the stirring and drying process, this will result in the inability to dry the inside of the material, and the size of the agglomerated material will be larger than the size of the conveying trough 301, resulting in the inability to discharge the material smoothly. Therefore, it is necessary to crush the agglomerated material. The annular groove 1201 is arranged by two symmetrical spiral grooves, and the number of spiral turns of each spiral groove is a quarter of a turn. The ends of the spiral groove 601 and the transverse groove 602 are connected to each other. In the initial state, the protrusion 1301 is located at the end of the stroke of the annular groove 1201 toward the side of the drive motor 5, so that the movable sleeve 8 is located at the end of the stroke toward the side of the drive motor 5, so that the limit block 11 is located at the end of the stroke of the spiral groove 601 away from the transverse groove 602. At this time, the angle between the second mixing blade 9 and the first mixing blade 7 is the largest, and the distance between the crushing plate 10 and the first mixing blade 7 is the largest. When the drive motor 5 is working, the first mixing blade 7 is driven by the transmission rod 6 along the crushing plate 10 that cooperates with it. The movable sleeve 8 also drives the support plate 13 to move, so that the protrusion 1301 slides in the annular groove 1201, so that the movable sleeve 8 moves in the direction away from the driving motor 5. The movable sleeve 8 also drives the limit block 11 to slide in the spiral groove 601, so that the angle between the second mixing blade 9 and the first mixing blade 7 is reduced, so as to reduce the distance between the crushing plate 10 and the first mixing blade 7. When the limit block 11 moves to the connection position of the spiral groove 601 and the transverse groove 602, the material will be placed between the crushing plate 10 and the first mixing blade 7. At this time, the movable sleeve 8 continues to move, so that the limit block 11 moves along the length direction of the transverse groove 602, so as to control the crushing plate 10 to move along the length direction of the first mixing blade 7, thereby realizing the crushing of the agglomerated material through the friction between the crushing plate 10 and the first mixing blade 7.

[0035] Preferably, when the protrusion 1301 moves to the end of the stroke of the annular groove 1201 away from the driving motor 5 side, the limit block 11 moves to the end of the stroke of the transverse groove 602 away from the spiral groove 601 side. At this time, the transmission rod 6 continues to rotate and drives the movable sleeve 8 to rotate through the limit block 11 and the transverse groove 602. The movable sleeve 8 will also control the protrusion 1301 to continue to slide along the annular groove 1201 through the support plate 13 and move toward the driving motor 5 to control the limit block 11 to move along the length direction of the transverse groove 602. During this process, the crushing plate 10 and the first mixing leaf 7 rub the material again and crush the material. When the limit block 11 disengages from the transverse groove 602 and enters the spiral groove 601, the movable sleeve 8 rotates relative to the transmission rod 6, so that the crushing plate 10 moves in the direction away from the first mixing leaf 7 until the distance between the crushing plate 10 and the first mixing leaf 7 returns to the initial state, and the above steps are repeated, thereby achieving the effect of crushing the agglomerated material by adjusting the distance between the crushing plate 10 and the first mixing leaf 7.

[0036] See also Figure 1-Figure 4 , a roller crushing mechanism is arranged on the support platform 1 and connected to the protective box 2, the roller crushing mechanism is connected to the first crushing roller 18 and the second crushing roller 22, the roller crushing mechanism includes a first motor 15 installed on the support platform 1, a first rotating rod 17 is rotatably installed in the protective box 2, the first rotating rod 17 is connected to the first crushing roller 18, the first rotating rod 17 is sleeved with a first belt 16 connected to the output shaft of the first motor 15, a reverse rotating component connected to the second crushing roller 22 is arranged on the support platform 1, wherein the reverse rotating component includes a slide groove 14 opened on the protective box 2, a second motor 19 is installed on the support platform 1, a second rotating rod 21 slidably connected to the slide groove 14 is rotatably installed in the protective box 2, the second rotating rod 21 is connected to the second crushing roller 22, and the second rotating rod 21 is sleeved with a second belt 20 connected to the output shaft of the second motor 19.

[0037] Further, after the material entering the hopper 3 is dried, it will enter the conveying pipe 4 through the conveying trough 301 and be conveyed to the protective box 2. The material will fall between the first crushing roller 18 and the second crushing roller 22. At this time, the first motor 15 and the second motor 19 are working, and respectively control the first rotating rod 17 and the second rotating rod 21 to rotate through the first belt 16 and the second belt 20, and the rotation directions of the first rotating rod 17 and the second rotating rod 21 are opposite to each other, so as to control the first crushing roller 18 and the second crushing roller 22 to rotate in the opposite direction. Under the action of the crushing roller, the material is crushed to ensure that the material is crushed into the required particle size. Among them, the second belt 20 has a certain elasticity and can be stretched or contracted to a certain extent. When it is necessary to adjust the crushed particle size of the material, under the action of the particle size control mechanism, the second rotating rod 21 moves toward or away from the first rotating rod 17, and the second belt 20 will shrink or stretch accordingly to adjust the distance between the second crushing roller 22 and the first crushing roller 18, thereby changing the crushed particle size of the material.

[0038] See also Figure 1-Figure 4 , a particle size regulating mechanism is arranged in the protective box 2 and connected to the roller crushing mechanism, the particle size regulating mechanism can adjust the distance between the second crushing roller 22 and the first crushing roller 18 through the roller crushing mechanism, the particle size regulating mechanism includes a cylinder 27 installed on the side wall of the protective box 2, a limiting plate 28 is arranged on the output end of the cylinder 27, a limiting groove 2801 is provided on the limiting plate 28 and is slidably connected to the second rotating rod 21, an elastic component connected to the second rotating rod 21 is arranged in the protective box 2, wherein the elastic component includes a support sleeve 25 installed in the protective box 2 and symmetrically arranged, a support rod 24 is slidably installed in the support sleeve 25, a movable plate 23 rotatably connected to the second rotating rod 21 is arranged at the end of the support rod 24, and a spring 26 abutting against the movable plate 23 is sleeved on the support sleeve 25 and the support rod 24.

[0039] Furthermore, in the initial state, the spring 26 is in a compressed state, so that the support rod 24 is located at the end of the stroke away from the support sleeve 25, so as to provide a certain thrust to the second rotating rod 21 through the movable plate 23, thereby ensuring that the second crushing roller 22 always has a certain pressure on the material. At this time, the second rotating rod 21 is located at the end of the stroke on the side of the limiting groove 2801 toward the first rotating rod 17. Under the action of the two crushing rollers, the material is crushed. If the material is mixed with metal or other substances of harder material, the crushing roller cannot crush it. Therefore, the second crushing roller 22 will give way and drive the second rotating rod 21 to slide along the slide groove 14 and the limiting groove 2801. The second rotating rod 21 will also drive the movable plate 23 to move, so that the support rod 24 moves toward the support sleeve 25, so that the spring 26 is compressed. When the material leaves the crushing roller, the spring 26 is elastically released, so that the second crushing roller 22 is reset, thereby ensuring that the crushing roller will not be scratched or damaged on the surface due to such substances.

[0040] Preferably, if it is necessary to increase the particle size of the material, the cylinder 27 works and drives the limit plate 28 to move, so that the limit slot 2801 moves. At this time, under the action of the limit slot 2801 and the second rotating rod 21, the second crushing roller 22 moves in the direction away from the first crushing roller 18, thereby increasing the particle size of the crushed material. If it is necessary to reduce the particle size of the material, the cylinder 27 controls the limit plate 28 to move toward the first rotating rod 17. At this time, the spring 26 is elastically released, so that the distance between the second crushing roller 22 and the first crushing roller 18 is reduced, thereby reducing the particle size of the crushed material.

The dried gas will be transported to the protective box 2 through the conveying pipe 4; Step 4: Under the action of the roller crushing mechanism, the first crushing roller 18 and the second crushing roller 22 rotate in opposite directions. Under the action of the crushing rollers, the material is crushed.
