Description

Technical Field

[0001] This application relates to the field of roller screen technology, and in particular to a roller screen device with emergency handling capabilities. Background Technology

[0002] In modern industrial production, especially in processes involving material sorting, grading, or impurity removal, roller screen systems are widely used as key equipment in various industries such as mining, metallurgy, chemicals, building materials, and food processing. This system uses a series of parallel rollers, utilizing the gaps between the rollers or a specific design structure, to screen and separate passing materials, effectively removing substandard products or impurities that do not meet specifications, ensuring the smooth operation of subsequent production processes and the stability of product quality.

[0003] Currently, the widely used roller screen systems generally adopt an independent transmission design for each roller, meaning each roller is connected to a complete transmission system, including components such as a reducer, motor, and coupling. While this design ensures the independence and flexibility of each roller's operation to a certain extent, as the scale of roller screen systems increases, such as large systems containing dozens or even hundreds of rollers, the complexity and failure rate of the transmission system also increase significantly.

[0004] In the existing technology, if a certain transmission device fails, the corresponding roller will lose power and cannot rotate normally, which will affect the normal feeding of materials and cause material blockage in part or the entire roller screen system. Material blockage not only leads to production interruption, but also requires a lot of time and manpower to shut down for maintenance, which seriously affects the continuous and stable operation of the production system. Therefore, it needs to be improved. Utility Model Content

[0005] To address the issue of production interruptions caused by a malfunction in a transmission device, this application provides a screen roller device with emergency handling capabilities.

[0006] The screen roller device with emergency handling capability provided in this application adopts the following technical solution:

[0007] An emergency handling device for screen rollers includes multiple sets of parallel screen rollers. Each screen roller is equipped with a transmission component for transmission. An emergency component is provided between each pair of adjacent screen rollers. The emergency component includes a base, a first bearing seat, a gear shaft, an emergency pinion, and two emergency large gears. The base is arranged between two screen rollers. The first bearing seat is connected to the base. The gear shaft is rotatably disposed within the first bearing seat. The emergency pinion is coaxially fixed in the middle of the gear shaft. The two emergency large gears are symmetrically arranged on both sides of the emergency pinion, and each emergency large gear meshes with the emergency pinion. Each emergency large gear is coaxially fixed with its corresponding screen roller.

[0008] If a transmission device malfunctions, the corresponding roller will lose power and cannot rotate normally, which will affect the normal feeding of materials and cause blockage in the local or entire roller screen system. Blockage not only leads to production interruption, but also requires a lot of time and manpower for shutdown and maintenance, which seriously affects the continuous and stable operation of the production system. By adopting the above technical solution, including multiple sets of screen rollers arranged in parallel, the screen rollers are equipped with a transmission mechanism and emergency components. The emergency components include a base, a first bearing seat, a gear shaft, an emergency pinion, and two emergency large gears.

[0009] When a fault occurs in the transmission mechanism of a screen roller, the abnormality is detected by the monitoring system or on-site inspection personnel. The specific location of the faulty screen roller is quickly determined for subsequent operations. Since the base and two emergency gears are pre-installed between the two screen rollers, there is no need to reinstall them. The transmission mechanism adjacent to the faulty screen roller is stopped to avoid accidents or interference when installing the emergency components. The pre-prepared assembly of the first bearing seat, gear shaft, and emergency pinion is taken out and installed on the base pre-positioned between the two screen rollers. Ensure that the gear shaft can rotate smoothly in the first bearing seat. Adjust the position of the emergency pinion so that it meshes correctly with the emergency gears pre-installed on both sides. Start the adjacent transmission mechanism. At this time, the rotation of the adjacent screen roller will drive the faulty screen roller to rotate through the transmission of the emergency gear, emergency pinion, and gear shaft, thereby realizing the emergency drive of the faulty screen roller. After ensuring the stable operation of the production system, the faulty transmission mechanism is repaired at a later time.

[0010] By incorporating screen rollers and emergency components, the problem of production interruption caused by transmission device failure was effectively solved, enabling emergency drive, significantly reducing downtime, ensuring normal material feeding, avoiding production stagnation and high maintenance costs caused by material blockage, ensuring continuous and stable operation of the production system, and allowing time to be allocated later for repairing the faulty transmission mechanism, thereby improving the reliability and production efficiency of the device.

[0011] Optionally, the transmission assembly includes a bracket, two second bearing seats, and a motor. The two second bearing seats are arranged at intervals along the length of the bracket and are rotatably connected to the two ends of the screen roller, respectively. The output end of the motor is connected to the end of the screen roller.

[0012] By adopting the above technical solution, the transmission component includes a bracket, two second bearing seats and a motor; the transmission component provides a stable rotational support for the screen roller, ensuring the smoothness of the screen roller's rotation and enabling stable operation to meet the work requirements such as material screening.

[0013] Optionally, a drive shaft is provided at one end of the screen roller near the motor, and a coupling is provided between the drive shaft and the motor. The drive shaft is connected to the output end of the motor through the coupling.

[0014] By adopting the above technical solution, the screen roller extends the drive shaft and is connected to the motor through a coupling. Through the setting of the drive shaft and coupling, the drive shaft acts as a bridge for power transmission, so as to smoothly and efficiently transmit the power generated by the motor to the screen roller. The coupling effectively buffers the vibration and impact between the motor and the screen roller, compensates for installation errors, ensures the continuity and stability of power transmission, and enhances the smoothness and reliability of the screen roller rotation.

[0015] Optionally, a speed reducer is connected in series between the motor and the coupling.

[0016] By adopting the above technical solution, a reducer is connected in series between the motor and the coupling; through the rated setting of the reducer, the reducer can accurately adjust the high-speed rotational motion output of the motor and convert it into a low-speed, high-torque power output suitable for the working requirements of the screen roller, effectively balancing the relationship between speed and torque in the power transmission process, and meeting the requirements of the screen roller for stable speed and sufficient driving force.

[0017] Optionally, the motors, reducers and couplings corresponding to two adjacent screen rollers are located on opposite sides of the screen rollers.

[0018] By adopting the above technical solution, the motors, reducers and couplings corresponding to two adjacent screen rollers are located on opposite sides of the screen rollers. By arranging the motors, reducers and couplings in a reasonable manner, the mutual interference between adjacent transmission components is effectively avoided. This not only improves the overall compactness and space utilization of the equipment, but also provides more ample operating space for daily maintenance and repair.

[0019] Optionally, the ratio of the number of teeth of the emergency pinion to the two emergency gears is 1:2, and they have the same module, so as to ensure that the adjacent screen rollers rotate at the same speed during emergency transmission.

[0020] By adopting the above technical solution, the gear ratio of the emergency pinion to the two emergency gears is 1:2, and the modules are the same. By setting the gear ratio, the rotation speed of the faulty screen roller driven by the emergency gears on both sides is kept consistent with that of the normal screen roller. This avoids material accumulation or uneven screening caused by speed differences, and ensures the power synchronization of the whole system in emergency situations.

[0021] Optionally, the inner hole of the emergency gear is provided with a key block, and the outer circumferential surface of the screen roller is provided with a keyway that matches the key block.

[0022] By adopting the above technical solution, the emergency gear is engaged with the keyway of the screen roller through a key block. The key block and keyway not only ensure the coaxiality and no relative sliding between the gear and the screen roller during power transmission, thus ensuring the high efficiency and stability of power transmission during emergency transmission, but also simplify the installation and disassembly process of the gear through the standardized keyway structure, thereby improving the convenience of equipment maintenance.

[0023] Optionally, the first bearing housing is provided with a plurality of fixing bolts for fixing to the base, and the plurality of fixing bolts are respectively arranged on both sides of the first bearing housing.

[0024] By adopting the above technical solution, the first bearing housing is installed on the base by fixing bolts; by setting the fixing bolts, the installation stress is evenly distributed in a multi-point positioning manner, ensuring the rigid connection between the first bearing housing and the base, and effectively avoiding structural deformation or loosening caused by single-point force.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting up screen rollers, emergency components, etc., the production interruption problem caused by transmission device failure is effectively solved, emergency drive is realized, downtime is greatly reduced, material is fed normally, production stagnation and high maintenance costs caused by material blockage are avoided, and the production system is ensured to operate continuously and stably. Time can be arranged to repair the faulty transmission mechanism later, thus improving the reliability and production efficiency of the device.

[0027] 2. By setting up a drive shaft and coupling, the drive shaft acts as a bridge for power transmission, smoothly and efficiently transmitting the power generated by the motor to the screen roller. The coupling effectively buffers the vibration and impact between the motor and the screen roller, compensates for installation errors, ensures the continuity and stability of power transmission, and enhances the smoothness and reliability of the screen roller rotation.

[0028] 3. By arranging the motor, reducer, and coupling in a reasonable manner, the mutual interference between adjacent transmission components is effectively avoided through the rational allocation of equipment space. This not only improves the overall compactness and space utilization of the equipment, but also provides more ample operating space for daily maintenance and repair. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0035] This application discloses a screen roller device with emergency handling capabilities. (Refer to...) Figure 1 The screen roller device with emergency handling capability includes multiple sets of parallel screen rollers 1. In this embodiment, the multiple sets of parallel screen rollers 1 form a roller screen system for material sorting, grading or impurity removal. Each screen roller 1 is equipped with a transmission component 2, which is used to drive the screen roller 1 to move.

[0036] Reference Figure 1 and Figure 2 The transmission assembly 2 includes a bracket 21, two second bearing seats 22 and a motor 23. The two second bearing seats 22 are mounted on the bracket 21 and are arranged at intervals along the length of the bracket 21. The two ends of the corresponding screen roller 1 are rotatably connected to the two second bearing seats 22 by bearings, and one end of the screen roller 1 extends out of the drive shaft 4.

[0037] Reference Figure 1 and Figure 2 The motor 23 is mounted on the bracket 21 and is located on the side of the screen roller 1 near the drive shaft 4. The output end of the motor 23 is equipped with a reducer 6. A coupling 5 is installed between the reducer 6 and the drive shaft 4. The coupling 5 can be a flexible coupling. When the motor 23 is started, the speed is matched and the torque is amplified by the reducer 6. The power is transmitted to the drive shaft 4 without loss through the coupling 5, thereby driving the screen roller 1 to rotate stably in the second bearing seat 22.

[0038] Reference Figure 1 and Figure 2The drive shaft 4 acts as a bridge for power transmission, smoothly and efficiently delivering the power generated by the motor 23 to the screen roller 1. The coupling 5 effectively buffers the vibration and impact between the motor 23 and the screen roller 1, compensates for installation errors, ensures the continuity and stability of power transmission, and enhances the smoothness and reliability of the screen roller 1's rotation. The reducer 6 can precisely adjust the high-speed rotational motion output by the motor 23, converting it into a low-speed, high-torque power output suitable for the working requirements of the screen roller 1, effectively balancing the speed and torque relationship in the power transmission process, and meeting the requirements of the screen roller 1 for stable speed and sufficient driving force.

[0039] Reference Figure 1 and Figure 2 Meanwhile, the motors 23, reducers 6 and couplings 5 ​​corresponding to the two adjacent screen rollers 1 are located on opposite sides of the screen rollers 1. By rationally allocating the equipment space, mutual interference between adjacent transmission components is effectively avoided, which not only improves the overall compactness and space utilization of the equipment, but also provides more ample operating space for daily maintenance and repair.

[0040] Reference Figure 1 and Figure 3 An emergency component 3 is installed between two adjacent screen rollers 1. The height of each level of screen roller 1 in the roller screen system is arranged from high to low from the receiving end to the discharge end through the bracket 21. The height of the emergency component 3 is adjusted according to the actual situation. The emergency component 3 includes a base 31, a first bearing seat 32, a gear shaft 33, an emergency pinion 34, and two emergency gears 35. The base 31 is installed on the ground and at the end of the screen roller 1, located between the two screen rollers 1. The first bearing seat 32 is installed on the base 31. In this embodiment, there are two first bearing seats 32. Several fixing bolts 9 for fixing to the base 31 are installed on the first bearing seat 32. Several fixing bolts 9 are respectively arranged on both sides of the first bearing seat 32. The gear shaft 33 is rotatably installed in the two first bearing seats 32. At the same time, the emergency pinion 34 is coaxially fixed in the middle of the gear shaft 33.

[0041] Reference Figure 1 and Figure 4 Two emergency large gears 35 are symmetrically arranged on both sides of the emergency small gear 34, and the two emergency large gears 35 mesh with the emergency small gear 34 respectively. The two emergency large gears 35 are coaxially fixed with the corresponding screen rollers 1 respectively. The inner hole of the emergency large gear 35 is provided with a key block 7, and the outer peripheral surface of the screen roller 1 is provided with a keyway 8 that matches the key block 7. In this embodiment, the base 31 and the two emergency large gears 35 are pre-installed accessories, and the accessories composed of the first bearing seat 32, the gear shaft 33 and the emergency small gear 34 are installed accessories during emergency handling.

[0042] Reference Figure 4The ratio of the number of teeth of the emergency pinion 34 to the two emergency gears 35 is 1:2, and the modules are the same, so as to ensure that the adjacent screen rollers 1 rotate at the same speed during emergency transmission; so that the speed of the faulty screen roller 1 driven by the emergency gears 35 on both sides is consistent with that of the normal screen roller 1, which not only avoids material accumulation or uneven screening caused by speed difference, but also ensures the power synchronization of the whole system in emergency state.

[0043] The implementation principle of a screen roller device with emergency handling capability in this application embodiment is as follows: When the transmission mechanism of a screen roller 1 malfunctions, the abnormality of the transmission mechanism of a screen roller 1 is detected by the monitoring system or on-site inspection personnel. The specific location of the faulty screen roller 1 is quickly located for subsequent operation. Since the base 31 and the two emergency large gears 35 are pre-installed between the two screen rollers 1, there is no need to install them again. The transmission mechanism adjacent to the faulty screen roller 1 is stopped to avoid accidents or interference when installing the emergency component 3. The pre-prepared first bearing seat 32, gear shaft 33 and emergency small gear are removed. The assembly 34 is installed on the base 31 pre-arranged between the two screen rollers 1, ensuring that the gear shaft 33 can rotate smoothly in the first bearing seat 32. The position of the emergency pinion 34 is adjusted so that it meshes correctly with the emergency gears 35 pre-installed on both sides. The adjacent transmission mechanism is started. At this time, the rotation of the adjacent screen roller 1 will drive the faulty screen roller 1 to rotate through the transmission of the emergency gear 35, the emergency pinion 34 and the gear shaft 33, thereby realizing the emergency drive of the faulty screen roller 1. After ensuring the stable operation of the production system, the subsequent time is arranged to repair the faulty transmission mechanism.

[0044] By setting up screen roller 1, emergency component 3, etc., the production interruption problem caused by transmission device failure is effectively solved, emergency drive is realized, downtime is greatly reduced, material is fed normally, production stagnation and high maintenance costs caused by material blockage are avoided, and the production system is ensured to operate continuously and stably. Time can be arranged to repair the faulty transmission mechanism later, thus improving the reliability and production efficiency of the device.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
