Description

Roller mill for raw cement processing

technical field

The invention belongs to the technical field of dredging equipment, in particular to a roller mill for cement raw material processing.

Background technique

The roller mill is a drying and grinding equipment with a wide range of uses. It can be widely used for grinding cement raw materials or cement clinker and other industrial raw materials such as construction, chemical industry and ceramics. The material is crushed under pressure between two rolling rolling surfaces or between a rolling grinding body (ball, roller) and a track (plane, ball, disc); mainly by the grinding track, grinding body, force It is composed of the generation and transmission mechanism, the flow of air and the device that facilitates the replacement of easy-change parts. With its unique advantages and characteristics in terms of working principle, grinding mechanism, mechanical structure and system process performance, roller mill has been paid more and more attention by the cement industry in the world and at home and abroad. With the birth of decomposition technology outside the kiln, the cement industry in various countries Roller mills are increasingly used to grind cement raw materials and clinker.

High-pressure roller mills are the most widely used in the prior art, and high-pressure roller mills are generally used in the crushing of ores in cement raw materials in the construction industry. Since the high-pressure roller mill implements quasi-static crushing, this quasi-static crushing method saves energy consumption compared with the impact crushing method, and the crushing effect is better, and the wear of the rollers is also small. There are two essential differences in technology. One is that the high-pressure roller mill implements quasi-static crushing, which saves about 30% of energy consumption compared with the impact crushing method; the other is that the high-pressure roller mill The material layer crushing is carried out on the material, which is the mutual crushing between the material and the material. The principle of lamination crushing is used to make a large number of micro-cracks, collapse, and looseness on the particle surface and inside of the material during the extrusion process, so that the roller mill product The bond work index can be greatly reduced and the grindability of the material can be improved. Compared with the traditional crushing and ball milling technology, the crushing efficiency of this principle is significantly improved, and the wear is also significantly reduced.

The existing high-pressure roller mill adopts two sets of roller bodies, and two motors drive the two grinding rollers to rotate in opposite directions through the reducer. One set is set as a fixed roll, and the other set is a moving roll. The fixed roller moves in the transverse direction to achieve material crushing and extrusion. The traditional high-pressure roller mill’s moving roller bearing seat is split, so it will inevitably cause the problem of roller deviation during use. , There is an offset phenomenon between the axis of the moving roll body and the axis of the fixed roll body, that is, the non-parallel phenomenon of the axes, which makes the size of the roll gap different, resulting in uneven force on the cake, and the position where the roll gap is large The pressure is small, the use effect is not good, the pressure in the small roll gap is too large, resulting in excessive wear of the roll surface, the problem of roll deviation greatly affects the use effect of the rolling machine and the service life of the roll surface; When it is pulled into the gap between the two rolls, because the particle size of the incoming raw material is difficult to control, the particle size difference is large, so that the material entering the roll gap is unevenly distributed along the axial direction, such as the front and rear sides The difference in particle size of the materials is too large, so that during the roller grinding process in the roll gap, the large particle size material will open the roll gap, so that the small particle size materials in the same axis direction can directly pass through the roll gap without being crushed. Direct outflow, even if there is a roll deviation phenomenon, the small particle size materials with large differences can still flow out from the roll gap on the same axis. If the surface pressure is too large, the service life of the roller body will be shortened, and the crushing efficiency will also be reduced. The large particle size material is not crushed sufficiently, and the small particle size material is not crushed or the crushing force is small, resulting in poor crushing effect. Therefore, we We hope to control the particle size range of the material entering the roll gap; at the same time, we also hope to monitor the overall rotation offset of the moving roll at any time during use, so we urgently need a cement raw material processing Roller mills are used to solve the above problems.

At the same time, it solves the problem of different positions on the same axis caused by the large particle size difference of the incoming materials in the high-pressure roller mill. Different roller surfaces are subjected to different forces, resulting in insufficient material crushing, reduced roller life, poor overall crushing effect, and low efficiency.

The output shaft of the drive motor 2 is usually set, and the distance between the two is adjusted according to the installation requirements. The output end of the drive motor 2 is installed. Universal coupling 3, the purpose of installation and setting of universal coupling 3 is to facilitate the process of adjusting the position of the roller body, and the power will not fail to transmit, that is to say, whether the roller body is used in the future If there is any deviation in any direction during the process, the power will not fail to transmit. The other end of the universal coupling 3 is equipped with a reducer 4 connected to the frame body 1, and the other end of the universal coupling 3 One end is coaxially connected with the input end of the reducer 4. The positions of the two sets of reducers 4 are sufficient to allow relative movement. The two sets of reducers 4 are mutually installed through brackets. Each reducer 4 is sleeved with a ring body, the two groups of rings are connected together by multi-angle connecting rods, so that when the follow-up moving roller is offset in the axial direction or in the lateral or longitudinal direction, it can be connected by the multi-angle connecting rod structure. Together, so that no rigid damage will occur, one of the rings is also hinged on the ground through a connecting rod structure, which facilitates the positional offset of the reducer 4 and its connected rollers;

There are two connecting frames 6, one is arranged on the left side of two groups of mounting rails 5, one group is arranged on the right side, and its triangular connecting frame 6 is arranged between two groups of mounting rails 5, and the triangular connecting frame 6 includes two A group of triangular plates 7 hingedly installed in the corresponding side mounting rails 5 and a fixed rod 8 installed longitudinally between the two groups of triangular plates 7, the two groups of triangular plates 7 are arranged parallel to the front and back, and are fixed by welding between the two groups of triangular plates 7 The rods 8 are fixedly connected to form a triangular connection frame 6 structure. One of the corners of the triangular plate 7 is hinged between two sets of guide rails of the installation rail 5, so that the triangular connection frame 6 formed can only be along the direction of the hinge axis. Rotate, the two groups of triangular plates 7 on the right side triangular connection frame 6 and the mounting rail 5 are provided with positioning pins 9 to meet the positioning of the right side triangle connection frame 6, and the two groups of triangular connection frames on the right side On the triangular plate 7 and the right side of the mounting rail 5, there are respectively positioning holes 66, and the positioning holes 66 at the same position are provided with cooperating studs 67 and nuts 68, where the triangular connection frame 6 and the mounting rail 5 are in the Positioning holes 66 are all set during manufacture, and its purpose is to facilitate manufacture, and the triangular connection frame 6 on the right side is owing to will install fixed roller by bearing seat, so by inserting nut 68 and screw on the position of positioning hole 66 on the right side. The structure of the column 67 realizes the positioning between the triangular connecting frame 6 and the mounting rail 5, so that the right triangular connecting frame 6 will not easily rotate and achieve the effect of positioning, while the left side does not need to be positioned, and the left side The purpose of the connecting frame is to install the moving roller through the bearing seat. The upper ends of the two sets of triangular plates 7 on the right frame are respectively hinged with hydraulic cylinders 10, that is to say, the two sets of triangular plates on the right side of the triangular connecting frame 6 The end position of the plate 7 is hinged with a hydraulic cylinder 10 that rotates along the vertical plane.

The specific setting of the hydraulic system here is the prior art, and the traditional hydraulic system is also set in this way, so I will not repeat it here. Compared with the old-fashioned For high-pressure roller mills, the hydraulic cylinder 10 and hydraulic rod 11 are set at the upper side, while the old-fashioned roller mills are set on one side of the roller mill, and the effect of extrusion and crushing is achieved by pushing the roller body laterally. The position of the hydraulic rod 11 and the hydraulic cylinder 10 of the roller mill in the invention is set on the upper side, far away from the hinge point of the triangular frame, so that the torque is increased. Compared with the old-fashioned high-pressure roller mill, by using a smaller The pressure of the roller body can be realized The extrusion and crushing effect between

The vibrating plate 19 and multiple The rotating shafts of the groups of revolving doors 18 are all driven to work with the power driving device installed on the frame body 1, so that the power driving device drives the vibrating plate 19 to reciprocate and vibrate along the rotating shaft, and simultaneously drives multiple groups of revolving doors 18 to open and close sequentially. The device can not only drive the vibration plate 19 to reciprocate vibration through power transmission, but the purpose of driving the vibration plate 19 to reciprocate vibration is to prevent cement raw materials from clogging on the screen. The power drive device can not only drive the vibration plate 19 to reciprocate vibration, but also drive different The revolving door 18 at each position is opened or closed sequentially, so that the temporary storage bins 17 at different positions are opened or closed sequentially, so that cement raw materials with different particle size ranges enter the roller gap for crushing treatment in sequence, and the processed Due to the small particle size range of the cement raw meal, the force on the roller body in the axial direction is uniform, and the service life of the roller body is prolonged. As for the specific structure of the power drive device, we will describe it in detail in the subsequent examples;

The upper end of the transition silo 14 is located above the rightmost screen and is provided with a feed inlet 21. The purpose of the feed inlet 21 being arranged at the rightmost end is to make the material in the process of screening, first screen the finer particles. This is also in line with the material screening process. A uniform feeding device is installed on the upper end of the transition silo 14 to meet the uniform transportation of cement raw materials to the feed port 21. The purpose of setting the uniform feeding device is to prevent the material from being Accumulation is carried out to prevent materials from entering the next screen for screening without effective screening. At the same time, it is also to ensure that the materials on the vibrating plate 19 are laid flat, so that too many materials will not be placed at one time. sufficient, so that the difference in particle size of the materials entering the corresponding temporary storage bin 17 is still too large, so we set up a uniform feeding device to uniformly distribute the material, and at the same time ensure that the screening efficiency of the screen is consistently maximized. No waste of resources, the specific structure of the uniform feeding device will be disclosed in subsequent embodiments;

The drive motor 2, hydraulic oil supply system, power drive device and uniform feeding device are all electrically connected to the controller installed on the frame body 1. The controller here adopts an integrated circuit chip structure. It is the chip structure of the single-chip microcomputer, which is used to control the working status and working time of each device. For example, the single-chip microcomputer controls the hydraulic oil supply system to charge and discharge oil to the hydraulic cylinder 10 according to the command, so as to apply the crushing pressure according to the roll gap, and drive Drive the motor 2 to work, thereby driving the universal joint 3 and the reducer 4 to work. The controller here is the prior art, and those skilled in the art can set related instructions according to actual needs, so it will not be done here To repeat, when this embodiment is in use, the connecting frame on the right is first positioned by the positioning pin 9, so that the upper rotating connecting roller body is a fixed roller, and the left roller body is a moving roller, and then the driving motor 2 and the hydraulic pressure are turned on. In the oil supply system, the cement raw meal is uniformly distributed through the uniform feeding device, and then the material is transported to the feed port 21 of the transition silo 14, wherein the uniform feeding device is opened and closed by the controller, and the uniformly distributed cement raw meal is passed The feed inlet 21 falls to the rightmost end of the vibrating plate 19, and the power drive device is turned on by the controller, which drives the vibrating plate 19 to reciprocate and vibrate, so that the material flows along the direction of the vibrating plate 19 beyond the bottom left, The vibration process can prevent the material from being stuck in the position of the sieve hole during the screening process. During the flow process, the cement raw meal with different particle sizes is screened, so that the screened cement raw meal with different particle size ranges is temporarily stored. Temporary storage is carried out in the feed bin 17, and at the same time, the driving device sequentially drives the revolving doors 18 below the temporary storage bins 17 at different positions to open or close sequentially. For example, after driving the right revolving door 18 to open, the particle size is less than The 10mm cement cement raw meal falls between the fixed roller and the moving roller for crushing, then the first right revolving door 18 is closed, and then the second right revolving door 18 is driven to open, so that the cement raw meal with a particle size range of 10-20mm enters Between the fixed roller and the moving roller for crushing, then the second right revolving door 18 is closed, and so on, and the cycle is set, so that the cement raw materials in different particle size ranges enter the roller gap for crushing, thereby improving the overall crushing efficiency After the material enters between the two groups of roller bodies, due to the specificity of the structure of the two groups of connecting frames, the moving roller can only rotate along the rotating hinge axis, thereby adjusting the roller gap, and the wrapping rings 65 on both sides of the fixed roller are also That is, the side flange can avoid the edge effect of the material on the roller mill. When the material with large particle size is crushed, the roll gap increases. The hydraulic oil supply system is used to supply oil to the hydraulic cylinder 10, increasing the size of the fixed roll and the moving roll. The pressure between the two groups of rollers allows the large particle size to be crushed. When the small particle size material enters the two groups of rollers for crushing, the distance between the roller gaps is also adjusted through the hydraulic oil supply system to reduce the roller gap. The distance between them can increase the crushing effect of small-size cement raw materials. Materials in the large-size range and small-size range are evenly arranged along the axial direction when they are transported between the two sets of rollers, so that different rollers The pressure between them is uniform, avoiding the problem of insufficient crushing treatment of large particle size materials in the same period of time, and the problem that small particle sizes cannot be crushed. The crushed materials flow out through the discharge port 13, and the materials at the discharge port 13 enter the follow-up The conveying equipment enters the classification equipment, and the materials smaller than a certain particle size after classification are sent to the subsequent section, and the coarse particles are returned to the high-pressure roller mill for re-extrusion, thereby completing the entire crushing process. This embodiment can effectively eliminate the old-fashioned traditional rollers. The roller deviation phenomenon of the press adopts the oil cylinder design on the top to increase the torque of the cylinder, and achieves a greater rolling effect with a smaller pressure. The side flange of the fixed roller wraps the moving roller to avoid the edge effect of the material, and the product is fine. The particle content is increased, and at the same time, the material is classified by particle size before entering the roll gap, so as to avoid the material with large particle size difference from entering the roll gap, resulting in insufficient crushing of large particle size materials, and no crushing phenomenon of small particle size materials, and the crushing effect is remarkable. , high crushing efficiency, energy saving, consumption reduction, production increase and efficiency increase.

Slow, so in the screening process of the screen structure on the vibrating plate 19, adjusting the amplitude of the vibration can adjust the screening speed, and reciprocating vibration can also prevent the screen holes from being blocked. If the screen structure on the vibrating plate 19 When the material layer passing through is too thick, the vibration amplitude needs to be smaller so that the material can be screened as much as possible; Screen as much as possible and pass through the screen structure as soon as possible to improve the screening efficiency.

The diameter of the first gear 31 is larger than that of the second gear 32. The purpose of setting the first gear 31 and the second gear 32 is to reduce the speed, so as to ensure that each temporary storage bin 17 can have sufficient time for unloading, so as to realize material crushing , the second gear 32 is coaxially installed with a sector gear 33 placed behind the transition bin 14, and the sector gear 33 is externally engaged with multiple groups of third gears 34 that are longitudinally rotatably connected to the frame body 1, and the sector gear 33 is sufficient to sequentially drive one group of third gears 34 to rotate, and the number of the third gears 34 corresponds to the number of revolving doors 18, that is to say, the teeth on the sector gear 33 are rotated during the process of sector gear 33 rotation Only one of the third gears 34 is meshed and rotated, and two sets of third gears 34 are not driven to rotate at the same time. Here we take four sets of temporary storage bins 17 as an example, that is, the third gear 34 is set to four , evenly distributed on the outer edge of the circumference of the sector gear 33;

It also includes a worm gear 35 coaxially installed at the rear end of the rotating shaft of the revolving door 18, and the worm gear 35 is engaged with a worm screw 36 connected to the rear end of the transition bin 14 for lateral rotation, and the transmission of the worm gear 35 and the worm screw 36 here is a self-locking transmission The structure satisfies that the worm 36 drives the worm wheel 35 to rotate, and the worm wheel 35 cannot drive the worm 36 to rotate, that is to say, the worm wheel 35 cannot reversely drive the worm 36 to rotate.

Rotate, thus realize that the revolving door 18 of the second temporary storage bin 17 on the left is closed, and the revolving door 18 of the second temporary storage bin 17 on the right is opened, and repeats itself, so as to drive the revolving door 18 of the temporary storage bin 17 from left to right to open Or the work of closing, such as driving the right first revolving door 18 to open, the cement cement raw material with a particle size less than 10mm falls between the fixed roller and the moving roller Then the first right revolving door 18 is closed, and then the second right revolving door 18 is driven to open, so that the cement raw material with a particle size range of 10-20mm enters between the fixed roller and the moving roller for crushing, and then the second right revolving door 18 off, and so on, and cycle settings, so that cement raw materials with different particle size ranges enter the roller gap for crushing, thereby improving the overall crushing efficiency. After the material enters between the two sets of rollers, due to the The specificity of the connecting frame structure makes the moving rollers only rotate along the hinged shafts to adjust the roll gap. The wrapping rings 65 on both sides of the fixed rollers, that is, the lateral flanges, can avoid the edge effect of the materials on the roller mill, greatly When the particle size material is crushed, the roll gap increases, and the hydraulic cylinder 10 is supplied with oil through the hydraulic oil supply system to increase the pressure between the fixed roll and the moving roll, so that the large particle size can be charged and crushed. When materials with small particle size enter into the two sets of rollers for crushing, the distance between the roller gaps is also adjusted through the hydraulic oil supply system to reduce the distance between the roller gaps, thereby increasing the crushing effect of small particle size cement raw materials , whether it is a large particle size range or a small particle size range, the material is evenly arranged along the axial direction when it is transported between the two sets of rollers, so that the pressure between different rollers is even, and the large particle size material is avoided in the same period of time. Breaking Insufficient treatment, small particle size cannot be crushed, the crushed material flows out through the discharge port 13, and the material at the discharge port 13 enters the subsequent conveying equipment and enters the classification equipment. After classification, the material smaller than a certain particle size The material is sent to the follow-up section, and the coarse particles are returned to the high-pressure roller mill for re-extrusion, thus completing the entire crushing process. This invention can effectively eliminate the roll deviation phenomenon of the old-fashioned traditional roller press, and adopt the oil cylinder design on the top to increase the cylinder torque. Use less pressure to achieve greater rolling effect. The side flange of the fixed roller wraps the moving roller to avoid the edge effect of the material, and the fine particle content of the product is increased. At the same time, the material is classified by particle size before entering the roller gap to avoid The material with large particle size difference enters the roller gap, resulting in insufficient crushing of large particle size materials, and no crushing phenomenon of small particle size materials. It is more uniform, prolongs the service life of the roller body and the roller surface, reduces the cost and improves the crushing efficiency at the same time.
