Description

Technical Field

[0001] The invention relates to the technical field of roller mills, and in particular to a high-efficiency roller mill for crushing and processing concrete materials. Background Art

[0002] Roller mill is a widely used drying and grinding equipment, which is widely used in the treatment of construction waste, highway waste concrete materials and road milling materials. When crushing materials, the high-pressure roller mill follows the principle of material bed crushing, that is, under the action of high pressure, the materials are fed from above the two rollers, and are continuously brought into the closed roller space by the extrusion rollers for continuous extrusion and crushing, and then form a dense cake for discharge;

[0003] Usually, before using a high-pressure roller mill to crush concrete materials, it is necessary to pre-crush them to prevent larger pieces of concrete materials from entering the roller mill and affecting the roller mill processing. Pre-crushing can be performed on larger pieces of concrete materials to break them into multiple small pieces of uneven size. Therefore, the pre-treated concrete materials may have uneven particle size. When the roller mill crushes concrete materials with uneven particle size, the extrusion pressure of the two rollers will be unbalanced due to the uneven particle size, resulting in vibration of the machine body. At the same time, the particle size of the produced concrete materials will be uneven and the quality will be poor. When the machine body vibrates during the processing, the operator fails to discover it in time, and after discovering the vibration, the batch of concrete materials needs to be discharged and crushed for a second time to adjust its particle size to be uniform before continuing to crush it. The continuous operation of the roller mill is affected, the overall processing efficiency is reduced, and the processing effect needs to be further improved. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention is provided with a concrete material pretreatment mechanism. After the concrete material enters the processing inner cylinder, the concrete material pretreatment mechanism can pretreatment the concrete material. In the process of the roller mill crushing the concrete material, the detection mechanism can detect the vibration of the two rollers. If the two rollers vibrate abnormally when the other hardware installation and debugging of the equipment are in a normal state, it means that the particle size of the concrete material entering the roller mill for crushing is uneven. The concrete material pretreatment mechanism is used to pretreatment the concrete material to ensure that the particle size of the concrete material entering the roller mill is uniform, and the vibration of the two rollers is detected by the detection mechanism to feedback the processing effect of the concrete material pretreatment mechanism. If the detection mechanism detects If abnormal vibration still occurs after the two rollers vibrate and the particle uniformity is adjusted, it is necessary to manually investigate and deal with the cause of the equipment abnormality. At the same time, during the crushing process, the thickness of the material bed accumulated on the upper side of the two rollers is detected by the material bed detection component to reflect the processing efficiency of the roller mill, and the feed speed is adjusted through the concrete material pretreatment mechanism according to the detected material bed thickness. When the detected material bed thickness is large but within the set safety range, the feed speed is reduced. If the detected material bed thickness is small but within the set safety range, the feed speed is increased. When the detected material bed thickness exceeds the set range, the cause is manually analyzed according to the abnormal parameters and corresponding adjustments are made, thereby improving the overall processing efficiency and processing effect of the roller mill.

[0021] The present invention is provided with a concrete material pre-processing mechanism. When a plurality of batches of concrete materials with uniform particle sizes and those with non-uniform particle sizes are crushed, the materials with uniform particle sizes enter the processing box and are scattered around under the action of the rotating dispersion plate 1 and the dispersion plate 2, so as to improve the uniformity of the feed. When the materials with non-uniform particle sizes enter the processing box, the crushing range of the extrusion crushing roller 1 and the extrusion crushing roller 2 on the particles can be adjusted by adjusting the positions of the extrusion platform 1 and the extrusion platform 2. The crushing range of the extrusion platform 1 and the extrusion platform 2 is adjusted according to the particle size of the non-uniform materials, and the large particles are crushed by the counter in cooperation with the extrusion platform 2 and the dispersion plate 2. The secondary pre-crushing treatment after the pre-crushing ensures the uniformity of particles in batches of materials with large differences in particle sizes. At the same time, when crushing different batches of concrete materials, the first material port and the second material port can be closed and opened by the dispersion plate 1 and the dispersion plate 2 to separate the two batches of particles with uneven particle sizes, and cooperate with the movement of the movable roller inside the roller mill and the action of the external elevator to guide the untreated uneven concrete material particles into the processing box for secondary processing. At the same time, when the extrusion table 1 and the extrusion table 2 are adjusted to pre-treat the particles, the detection mechanism is used to detect the vibration of the two rollers to reflect the adjustment of the particle size uniformity.

[0022] The present invention is provided with a material level detection component. When pre-treating concrete material particles to ensure their uniformity, the extrusion table one and the extrusion table two rotate to pre-treat the concrete material. The driving shaft two keeps rotating in the positive direction during the pre-treatment. When the driving shaft two rotates, the movable bevel gear one cooperates with the movable bevel gear two to drive the movable shaft to rotate in the positive and reverse directions. The material level sensor can move along the width direction of the material bed during feeding and detect the thickness of the material bed. If the thickness of the material bed is detected to be abnormal but within the set range, the corresponding processing operation is performed. If the thickness of the material bed exceeds the set range, the cause of the abnormality is manually investigated and processed.

[0023] The present invention is provided with a detection mechanism. When pre-treating concrete materials with uneven particle sizes, the concrete materials are pre-treated by the extrusion platform 1, the extrusion crushing roller 1, the extrusion platform 2 and the extrusion crushing roller 2. The pre-treated concrete materials enter the roller mill for crushing. When the extrusion platform 1 and the extrusion platform 2 are adjusted to uniformly adjust the particle size of the concrete materials, the particle size adjustment is reflected by detecting the vibration of the two rollers. If the particles of the pre-treated concrete materials are still uneven during the adjustment process, the vibration is transmitted to the coupling and causes the coupling to vibrate. At this time, the fixed ring plate on the vibrating coupling contacts the movable block, the contact sensor contacts the fixed ring plate and feeds back a contact signal, and the synchronous distance sensor starts to detect the distance between the movable block to reflect the vibration of the coupling. If the vibration of the coupling is eliminated, the material particle size adjustment is completed, and the subsequent processing operation continues. If the feeding particle size is uniform but abnormal vibration of the coupling is still detected, manual maintenance is required. BRIEF DESCRIPTION OF THE DRAWINGS

If the vibration of the coupling 15 is eliminated, the material particle size adjustment is completed and the subsequent processing operation continues. If the feeding particle size is uniform but abnormal vibration of the coupling 15 is still detected, manual maintenance is required.

[0042] When the present invention is in use, the concrete material blocks that have been initially crushed enter the processing box 2 for pretreatment and then enter the roller mill 1. The concrete material is fed into the roller mill 1 from above the fixed roller 17 and the movable roller 16. The concrete material is brought into the roller gap by the two rollers and forms a cake under high pressure to be discharged as a discharge material.

[0043] The concrete material enters the processing inner cylinder 22 from the feed guide plate 21. After the concrete material falls from the first material port, it is scattered around and falls downward to the middle area between the first material port and the second material port under the action of the rotating dispersion plate 1 33, and is pre-processed for the first time in the primary processing area. After the first pre-processing is completed, it can enter the secondary processing area again for the second pre-processing. When the concrete material is in the primary processing area, the extrusion table 1 32 rotates, and synchronously, the extrusion crushing roller 1 321 on the extrusion table 1 32 rotates synchronously under the action of the connecting bevel gear 1 41, the driving gear 1 43, the connecting bevel gear 2 44 and the driving gear 2 45. The concrete material can be pre-processed for the first time in the primary processing area through the extrusion table 1 32 and the extrusion crushing roller 1 321, and then the concrete material falls into the secondary processing area and is pre-processed for the second time through the cooperation of the rotating extrusion table 2 34 and the extrusion crushing roller 2 341. After the two pre-processing, the concrete material can enter the roller mill 1 for crushing.

[0044] When the extrusion station 1 32, the extrusion crushing roller 1 321, the extrusion station 2 34 and the extrusion crushing roller 2 341 pre-treat the concrete material, the positions of the extrusion station 1 32 and the extrusion station 2 34 are adjusted according to the particle size of the incoming concrete material to change the particle size range of the pre-treated concrete material. When the extrusion station 1 32 is adjusted downward, the gap between the extrusion station 1 32 and the inner wall of the processing inner cylinder 22 is reduced, and the particle size range of the concrete material that can pass through the gap is reduced. Similarly, when the extrusion station 2 34 is adjusted downward, the gap between the extrusion station 2 34 and the processing inner cylinder 22 is reduced, and the particle size range of the concrete material that can pass through the gap is reduced. Before processing, the positions of the extrusion station 1 32 and the extrusion station 2 34 are adjusted according to the overall average particle size range of the concrete material.

[0045] If the particle size of a batch of concrete materials is relatively uniform, the concrete materials with uniform particle size do not need to be processed after entering the processing box 2. When the concrete material particles descend in the processing box 2, they are scattered around and fall under the action of the first and second dispersion plates 33 and 35 and enter the roller mill 1 for crushing.

[0046] If the first batch of concrete material particles with uniform particle size is crushed, and then the second batch of concrete material particles with uneven particle size are crushed, after the uneven particle size materials enter the roller mill 1, the dispersion plate 2 35 is controlled to move to the second material port for blocking. After the previous batch of materials is completely discharged, the dispersion plate 1 33 is controlled to block the first material port, and the dispersion plate 2 35 is controlled to descend and separate from the second material port. At the same time, the hydraulic system is controlled to drive the movable roller 16 to move to increase the roller gap size between the movable roller 16 and the fixed roller 17. At this time, the unbroken materials in the primary processing area are discharged and conveyed to the external elevator through the conveyor belt (see the specific lifting circulation route). Fig.11As shown), the crushed concrete granules are lifted by an external lifting machine and conveyed to the feed guide plate 21 through a belt for re-feeding. Subsequently, the positions of the extrusion platform 1 32 and the extrusion platform 2 34 are adjusted according to the particle size of the second batch of concrete materials. If the particle size of the larger particles in the second batch of concrete materials is between 30 mm and 40 mm, the particle size of the medium particles is between 10 mm and 29 mm, and the particle size of the smaller particles is less than 10 mm, the extrusion platform 1 32 is controlled and adjusted to move to a crushed particle size of 30 mm, and the extrusion platform 2 34 is controlled to move to a crushed particle size of 1 0mm, synchronously, when the extrusion platform 32 is adjusted in place, the dispersion plate 33 descends, the first material port is opened, and the concrete material enters the processing inner cylinder 22. The concrete material with a particle size less than 30mm passes through the primary processing area and enters the secondary processing area for a second pre-grinding. When the concrete material with a particle size of 30mm-40mm mixed in the material enters between the extrusion platform 32 and the dispersion plate 33, it will be stuck between the extrusion platform 32 and the inner wall of the processing inner cylinder 22. At this time, the speed of the driving shaft 31 decreases, and the counter 313 unit time The number of pressed triggers decreases, and at this time, the extrusion platform 1 32 is controlled to move up to the position where the crushing particle size is 40mm. Synchronously, the dispersion plate 1 33 rises to reduce the feeding speed. Then the extrusion platform 1 32 is pressed down and rotated synchronously to crush the larger pieces of concrete materials. At this time, the large pieces of concrete materials may be crushed into multiple small pieces of uneven sizes after being crushed. When the large pieces of concrete materials are crushed, the speed of the extrusion platform 1 32 returns to normal, and synchronously, the extrusion platform 2 34 and the dispersion plate 2 35 are controlled to move up, and the crushed large pieces of concrete materials fall to the extrusion platform 2 In the gap between the second dispersing plate 35 and the processing inner cylinder 22, when the second dispersing plate 35 moves to the second material port, the second extrusion platform 34 is controlled to descend. While the second extrusion platform 34 descends, the crushed large concrete material particles falling between the second extrusion platform 34 and the processing inner cylinder 22 are squeezed and rotated to crush. When the second extrusion platform 34 descends and resets to a crushed particle size of 10 mm, the second extrusion platform 34 stops moving, and then the second dispersing plate 35 descends, and the crushed concrete material falls downward onto the second dispersing plate 35 and is thrown downward and enters the roller mill 1 for crushing.

[0047] When the particle size is adjusted, the uniformity of the particle size can be reflected by vibrating the two rollers. If the concrete material is still uneven in particles after pretreatment during the adjustment process, the vibration is transmitted to the coupling 15 and causes the coupling 15 to vibrate. At this time, the fixed ring plate 52 on the vibrating coupling 15 contacts the movable block 513, and the contact sensor 514 contacts the fixed ring plate 52 and feeds back a contact signal. The synchronous distance sensor 512 starts to detect the distance between the movable block 513 to reflect the vibration of the coupling 15. If the vibration of the coupling 15 is eliminated, the material particle size adjustment is completed and the subsequent processing operation continues. If the feeding particle size is uniform but abnormal vibration of the coupling 15 is still detected, manual maintenance is required at this time.

[0048] After the second batch of materials with uneven particles is processed, the extrusion platform 1 32 and the extrusion platform 2 34 are controlled to move and reset, and at the same time, the dispersion plate 1 33 is controlled to move up to block the first material inlet. After the second batch of materials is completely processed and discharged, the dispersion plate 1 33 is controlled to descend, and the third batch of materials enters the processing box 2, and corresponding adjustments are made according to the particle size uniformity of the third batch of concrete materials;

[0049] When the extrusion table 2 34 and the extrusion crushing roller 2 341 crush the concrete material, a positive and negative regular alternating rotation crushing method is adopted, so that the concrete material can receive extrusion force and shear force in different directions during the secondary treatment, so that the concrete material particles after the secondary treatment are more uniform;

[0050] When the concrete material enters the processing inner cylinder 22 and is scattered and dispersed by the dispersion plate 33 before entering the primary processing area for the first processing, the external suction fan performs suction operation through the circulation cover 23 and the fine powder discharge pipe 24, and part of the concrete material fine powder mixed in the concrete material is directly sucked into the circulation cover 23. After the processing is completed, the detachable plate at the bottom of the circulation cover 23 can be disassembled to discharge the concrete material fine powder, thereby avoiding the problem of excessive concrete material fine powder mixed in the concrete material, which affects the normal processing of the roller mill 1;

[0051] When the driving shaft 2 36 rotates to drive the extrusion table 2 34 to perform secondary processing on the concrete material, the driving shaft 2 36 drives the movable bevel gear 1 361 to rotate synchronously. When the movable bevel gear 1 361 rotates, it meshes with the movable bevel gear 2 362 and drives the movable shaft 363 to rotate. When the movable shaft 363 rotates forward and reversely, it drives the extension frame 364 to move laterally on the upper side of the material bed to detect the thickness of the material bed. The processing efficiency of the roller mill 1 is reflected according to the thickness of the material bed detected at various locations, and the speed of the material entering the roller mill 1 is adjusted to ensure the stable operation of the roller mill 1.
