Description

[0001] The present invention relates to the technical field of grinding devices, and specifically to a double roll press parallel grinding device. Background Art

[0002] The roll press grinding device is a high-efficiency and energy-saving grinding equipment, which is widely used in industries such as cement, mining, and metallurgy. It is mainly used for pre-grinding or final grinding of materials. Its core principle is to extrude and crush materials through high-pressure roll pressing. Compared with traditional ball mills, it has the advantages of low energy consumption, high efficiency, and uniform particle size distribution.

[0003] However, when the existing roll press grinding device is in use, if the material has too high viscosity (such as clay with a moisture content exceeding 5% or some slag), it is easy to adhere to the roll surface or the feed inlet, resulting in blockage or uneven feeding, affecting the operation efficiency, and the roll sleeve needs to be repaired or replaced regularly, and the replacement steps are relatively cumbersome.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a double roll press parallel grinding device is proposed. Summary of the Invention

[0016] The present invention provides a double-roller press parallel grinding device, which has the following beneficial effects: During use, the material can be heated and dried to remove its moisture, facilitating scraping it from the device to avoid adhesion. Moreover, the floating dust generated during grinding can be sucked by air flow to prevent it from escaping to the outside.

[0017] 1. When the present invention is in use, the roller plate can be disassembled and assembled conveniently, so that it can be repaired and replaced. During installation, it can be restricted to avoid the infiltration of materials into the gap due to skewed installation. And during use, the materials can be heated and dried by the roller plate to prevent the materials from being too viscous and adhering to the surface of the roller plate, which is difficult to clean or may cause blockage. Also, during the grinding process, the roller plate can be continuously cleaned to keep it clean and avoid the materials from being compressed and caked on the roller plate.

[0018] 2. When the present invention is in use, the heated air flow can be sent into the roller shaft to heat the materials. And during the air flow circulation, the floating dust stirred up in the feed inlet can be sucked and collected by the air flow to prevent the floating dust from escaping to the outside. Also, the vibrating screen cylinder can be knocked to remove dust by the self-vibration of the device during operation to prevent dust from accumulating on the screen cylinder and causing blockage, which affects the air flow circulation, and also prevent dust from entering the roller shaft. And when the hot air flow passes through the dust collection frame, the materials put into the feed inlet can also be preheated by the fuselage to reduce the drying time.

[0019] 3. When the present invention is in use, the movable roller shafts on both sides can be moved synchronously to adjust the distance between the roller shafts, and then the materials can be ground according to different requirements. And during the adjustment, the hot air inside the air cavity can be prevented from flowing out to damage the air flow circulation. At the same time, it can also be ensured that the two adjacent roller shafts can rotate in opposite directions synchronously before and after the movement. And when a certain roller shaft on one side has a fault such as being stuck, the fault can be repaired without affecting the operation of the roller shaft on the other side. During the normal operation of the device, the weighing scales inside the partition wall can weigh the materials entering both sides, and then control the rotation of the material distribution plate according to the weighing results, so that the materials put into the feed inlet can enter evenly between the roller shafts on both sides, and the roller presses on both sides can grind simultaneously. And when a fault occurs on one side or the operating load is too large, the feeding to that side can be stopped to prevent the materials from overflowing or increasing the working load.

The ventilation pipe 406 is connected to the ventilation groove 402, and the ventilation pipe 406 communicates with the ventilation passage 411 through the ventilation port 412.

The air cavity 16 communicates with the ventilation pipe 406 through the ventilation groove 402;

[0029] The specific operation is as follows. During use, the roller plate 409 can be conveniently disassembled and assembled, so as to repair and replace it. During installation, it can be restricted to prevent the material from seeping into the gap due to skewed installation. During use, the material can be heated and dried by the roller plate 409 to prevent the material from being too sticky and adhering to the surface of the roller plate 409, which is difficult to clean or causes blockage. During the grinding process, the roller plate 409 can be continuously cleaned to keep the roller plate 409 clean, preventing the material from being pressed and caked on the roller plate 409. During use, the heated air flow can be sent into the roller 401 to heat the material. During the air flow circulation, the floating dust stirred up in the feed inlet 5 can be sucked and collected by the air flow to prevent the floating dust from escaping to the outside. The sieve cylinder 9 can be knocked and dusted by the self-vibration of the device during operation to prevent dust from accumulating on the sieve cylinder 9 and causing blockage, affecting the air flow, and also preventing dust from entering the roller 401. When the hot air flow passes through the dust collection frame 8, the material put into the feed inlet 5 can also be preheated through the fuselage 1 to reduce the drying time.

[0030] Please refer to Figure 1 and Figures 4 to 6, symmetric sliding grooves 18 are provided on both sides of the air chamber 16, and limiting plates 19 are symmetrically connected inside the air chamber 16. A sliding frame 20 is engaged and slidably connected between the limiting plates 19. A turntable 21 is engaged and connected to one side of the sliding frame 20. A threaded rod 22 is threadedly connected to one side of the turntable 21 on the front side of the fuselage 1, and a dual-axis motor 23 is connected between the threaded rods 22. The sliding frame 20 is engaged and rotatably connected to the roller 401 on the side away from the partition wall 2. A driving frame 24 is provided at the rear side of the fuselage 1, and a driving motor 25 is connected to the middle of the driving frame 24. A driving wheel 26 is connected to one side of the driving motor 25, and transmission wheels 27 are symmetrically provided on both sides of the driving wheel 26. A transmission rod 28 is provided in the center of the transmission wheels 27, and a synchronous wheel 29 is provided on one side of the transmission wheels 27. The synchronous wheel 29 is connected to the turntable 21 through a universal coupling and a spline shaft, and the turntable 21 and the transmission rod 28 are both connected to the roller 401 through magnetic couplings. A material distribution plate 30 is provided on one side of the partition wall 2, and a material distribution motor 31 is connected to one side of the material distribution plate 30. Weight meters are symmetrically provided inside the partition wall 2, and the weight meters are connected to the material distribution motor 31;

[0031] The specific operation is as follows. When in use, the movable rollers 401 on both sides can be moved synchronously, so as to adjust the distance between the rollers 401, and then grind the materials according to different requirements. And when adjusting, the hot air inside the air chamber 16 can be prevented from flowing out, which may damage the air flow circulation. At the same time, it can also ensure that the two adjacent rollers 401 can rotate in opposite directions synchronously before and after the movement. And when a certain roller 401 is stuck or fails, the fault can be repaired without affecting the operation of the rollers 401 on the other side. When the device is running normally, the weight meters inside the partition wall 2 can weigh the materials entering both sides, so as to control the rotation of the material distribution plate 30 according to the weighing results, so that the materials put into the feed inlet 5 can evenly enter between the rollers 401 on both sides, and the roller presses on both sides can grind at the same time. And when a fault occurs or the operating load on one side is too large, the feeding to that side can be stopped to prevent the materials from overflowing or increasing the working load.

[0032] In summary, for the double-roller press parallel grinding device, when in use, first start the heater 15 and the air pump 13, so that the hot air flow enters the roller shaft 401 from the air cavity 16 through the ventilation groove 402, and then enters the ventilation channel 411 through the ventilation pipe 406 and the ventilation port 412 to heat the roller plate 409. After the air flow is drawn out from the roller plate 409 by the air pump 13, it can enter the dust collection frame 8 through the exhaust pipe 12, and then return to the roller shaft 401 through the intake pipe 14 to complete the circulation of the air flow. The heater 15 can continuously heat the air flow in the intake pipe 14 to maintain the temperature of the air flow. After the roller plate 409 is heated for a period of time, the material is put in from the feed port 5, and the distributor plate 30 evenly distributes the material into the chambers on both sides of the partition wall 2. The weighing meters on both sides of the partition wall 2 weigh the material entering the chambers and monitor the material load in the chambers on both sides in real time. During normal operation, the weighing meter controls the distributor motor 31 to drive the distributor plate 30 to rotate according to the weight of the material entering the chamber, so as to keep the amount of material entering the chambers on both sides balanced. When one of the weighing meters detects that the load exceeds the standard or the roller shaft 401 is stuck, the distributor motor 31 drives the distributor plate 30 to deflect and stop distributing the material to the faulty side, avoiding equipment overload or material overflow. When grinding the material, the driving motor 25 drives the driving wheel 26 to drive the transmission wheel 27 and the synchronous wheel 29 to rotate in opposite directions through the transmission rod 28 and the turntable 21 respectively, so as to drive the roller shafts 401 in the same-side chamber to rotate in opposite directions, making the roller plate 409 perform high-pressure extrusion grinding on the material. The floating dust generated by grinding rises and enters the feed port 5. Because the air flow in the dust collection frame 8 will form a negative pressure at the dust suction groove 7, the dust is sucked into the dust collection frame 8 from the dust suction groove 7. After the dust is intercepted by the sieve cylinder 9, the clean air flow enters the intake pipe 14 for circulation. As the device operates, the vibration of the device itself will drive the knocking plate 11 to vibrate repeatedly in the dust collection frame 8 through the knocking spring 10, so as to knock and remove dust from the sieve cylinder 9, avoiding dust accumulation on the sieve cylinder 9 causing blockage and affecting air flow circulation, and also preventing dust from entering the roller shaft 401. When the hot air flow passes through the dust collection frame 8, it can also preheat the material put into the feed port 5 through the fuselage 1 to reduce the drying time. And during the circulating flow of the hot air flow, it can continuously heat the roller plate 409 to dry the material, reduce the humidity of the material, and avoid the material being too sticky and adhering to the surface of the roller plate 409, making it difficult to clean or causing blockage. During the grinding process, the partition wall 2 and the sliding seat 3 can always clean the surface of the roller plate 409 to keep the roller plate 409 clean and avoid the material being pressed into lumps on the roller plate 409. During use, according to different particle size requirements, the double-shaft motor 23 drives the threaded rods 22 on both sides to block synchronously, thereby driving the turntable 21 to slide in the sliding groove 18, making the sliding frame 20 move in the air cavity 16, and driving the roller shaft 401 overflowing from the chamber away from the partition wall 2 to move synchronously along the sliding groove 18, and then adjusting the distance between the roller shafts 401. When the roller shaft 401 moves, the sliding seat 3 can move synchronously, and the limiting plate 19 can limit the sliding frame 20.Keep the sliding frame 20 in a horizontal state, avoid skewing of the sliding frame 20, ensure that the sliding frame 20 can always block the sliding groove 18, prevent a large amount of hot air flow in the air chamber 16 from overflowing from the sliding groove 18, and affect the air flow circulation. Before and after the movement of the roller shaft 401, the synchronous pulley 29 can maintain the connection with the turntable 21 through the universal coupling and the spline shaft, and always keep the opposite rotation state of the roller shaft 401 in the same side chamber. When a fault such as jamming occurs in the roller shaft 401 on one side, since the turntable 21 and the transmission rod 28 are both connected to the roller shaft 401 through the magnetic coupling, when the roller shaft 401 cannot rotate, the driving motor 25 can continue to operate normally and drive the roller shaft 401 on the other side for grinding, without increasing the load on the driving motor 25, which can avoid damage to the driving motor 25 due to excessive load. At the same time, it is also possible to repair the faulty part without affecting the operation of the roller shaft 401 on the other side.,
