Description

Technical Field

[0001] The present application relates to the technical field of sound monitoring systems, and in particular to a sound monitoring system for a reclaimer rotary mechanism and an application process thereof. Background Art

[0002] The main function of the slewing device on the bucket wheel stacker reclaimer is to enable the bucket wheel stacker reclaimer to rotate so as to retrieve or stack materials at multiple locations. When stacking materials, the materials are sent to the designated location through the conveyor arm and piled into a pile. When reclaiming materials, the bucket wheel digs the materials from the pile and sends them to other equipment or transportation tools.

[0003] The bucket wheel stacker can rotate flexibly through the slewing device, thereby expanding the operating range and improving the operating efficiency. The slewing device on the bucket wheel stacker is mainly composed of a drive variable frequency motor, a safety coupling, a vertical planetary reducer, a slewing bearing, and an open gear or a pin gear. The slewing bearing is the core component of the slewing device, which can keep the bucket wheel stacker stable during rotation and bear most of the load and torque. The working mode of the slewing bearing is that the inner ring is fixed and plays a supporting role, and the outer ring rotates. That is to say, in the application of the bucket wheel stacker, the inner ring of the slewing bearing is usually fixed to the base or frame of the equipment as a supporting basis, while the outer ring is connected to the main part of the slewing device and rotates with the rotation of the driving device.

[0004] However, the slewing bearing may make abnormal noises due to the friction between the bearing components during its rotation. Since the bucket wheel stacker reclaimer has a large structure and makes loud noises during operation, the abnormal noises are often not detectable by human ears. The damage to the slewing bearing is often discovered only after the slewing bearing is severely damaged to the point that it stops working and cannot rotate. As a result, the slewing bearing is severely damaged and cannot be repaired. The slewing bearing needs to be replaced, and the bucket wheel stacker reclaimer needs to be disassembled as a whole to replace the equipment, which is troublesome and wastes manpower and material resources. Summary of the invention

[0005] The purpose of the present application is to provide a sound monitoring system for the slewing mechanism of a reclaimer and its application process, which is used to solve the problem in the related art that the damage of the slewing bearing can only be detected after the slewing bearing is severely damaged to the point that it stops working and cannot rotate, resulting in the slewing bearing being severely damaged and unable to be repaired, and the bucket wheel stacker reclaimer needs to be disassembled and replaced as a whole, wasting manpower and material resources.

[0006] In the first aspect, the present application provides a sound monitoring system for a reclaimer rotary mechanism using the following technical solution:

If the sound does not change much and continues, it means that the rotating mechanism is damaged, has a large displacement or is improperly installed, and it is necessary to shut down the material reclaimer and disassemble the rotating mechanism for inspection and repair; if the sound stops, it means that the rotating mechanism is insufficiently lubricated; if the sound becomes smaller, it means that contaminants have entered the rotating mechanism, and the lubricating oil plays a certain buffering role in the rotating mechanism to reduce the sound to a certain extent.

[0013] At this time, continue to introduce lubricating oil to discharge the lubricating oil mixed with pollutants out of the rotating mechanism.

If the noise in the rotating mechanism cannot stop after two oil discharges, it means that the pollutants in the rotating mechanism are stuck tightly, and it is necessary to shut down the reclaimer and disassemble the rotating mechanism for repair.

[0014] The damage of the slewing bearing will not be known until the slewing bearing is severely damaged and stops working and cannot rotate.

[0022] By adopting the above technical solution, the fourth through hole on the side of each oil storage body provided with the fourth through hole is connected to the fifth through hole on the side of the adjacent oil storage body provided with the fifth through hole through a connecting pipe, so that the balance of air pressure in each oil storage body can be maintained.

[0023] Optionally, a sealing cover is further included, and a sixth through hole is opened on the oil storage body, and the sealing cover can seal the sixth through hole.

[0031] In the second aspect, the application process of the sound monitoring system of the reclaimer rotary mechanism provided by the present application adopts the following technical solution:

[0032] The following steps are involved:

[0033] S1: When the earpiece detects abnormal sound, lubricating oil is introduced into the rotary mechanism and the rotary mechanism continues to run for a period of time. The earpiece continues to monitor the rotary mechanism. If the sound does not change much and continues, it means that the rotary mechanism is damaged, has a large displacement or is improperly installed. It is necessary to stop the reclaimer and disassemble the rotary mechanism for maintenance;

[0034] S2: If the sound stops, it means that the rotary mechanism is not lubricated enough;

[0035] S3: If the noise becomes smaller, it means that pollutants have entered the rotary mechanism. The lubricating oil plays a certain buffering role in the rotary mechanism, which reduces the noise to a certain extent. At this time, continue to introduce lubricating oil to discharge the lubricating oil mixed with pollutants out of the rotary mechanism.

[0036] S4: If the noise in the rotary mechanism stops, it means that the pollutants have been discharged from the rotary mechanism; if the noise in the rotary mechanism cannot stop after two oil drains, it means that the pollutants in the rotary mechanism are stuck tightly, and it is necessary to stop the reclaimer and disassemble the rotary mechanism for inspection and maintenance.

[0037] By adopting the above technical scheme, the damage of the slewing bearing will not be discovered until the slewing bearing is severely damaged and stops working and cannot rotate. The problem that the slewing bearing is severely damaged and cannot be repaired and the slewing bearing needs to be replaced and the bucket wheel stacker reclaimer needs to be completely disassembled and replaced, which is troublesome and wastes manpower and material resources is solved.

[0038] In summary, the present application includes at least one of the following beneficial technical effects:

[0039] 1. When the earpiece detects abnormal sound, lubricating oil flows out of the oil pipe and flows to the ball bearing. Continue to run the rotary mechanism for a period of time, and the earpiece continues to monitor the rotary mechanism. If the sound does not change much and continues, it means that the lubricating oil continues to flow to the ball bearing and flushes the ball bearing but still has no effect. This means that the rotary mechanism is damaged, has a large displacement or is improperly installed. It is necessary to stop the reclaimer and disassemble the rotary mechanism for inspection;

[0040] If the noise stops, it means that the rotary mechanism is not lubricated enough. After the lubricating oil is introduced into the ball bearing, the rotary mechanism can work normally, the noise stops, and the oil stops flowing out of the oil pipe.

[0041] If the noise gets smaller, it means that pollutants have entered the rotary mechanism. The lubricating oil plays a certain buffering role in the rotary mechanism, which reduces the noise to a certain extent. Since the noise has not stopped, the lubricating oil continues to flow into the oil pipe. When the lubricating oil reaches a certain amount, the block in the oil tank is separated from the second through hole, and the lubricating oil mixed with pollutants in the oil tank is discharged from the rotary mechanism, and new lubricating oil continues to flow into the ball bearing. If the noise in the rotary mechanism stops, it means that the pollutants have been discharged from the rotary mechanism and the oil pipe stops flowing. If the noise in the rotary mechanism cannot stop after two oil discharges, it means that the pollutants in the rotary mechanism are stuck tightly, and it is necessary to shut down the reclaimer and disassemble the rotary mechanism for repair.

[0042] 2. When the earpiece detects an abnormal sound, the sound signal on the earpiece is converted into a mechanical vibration signal and transmitted to the oil push rod. The oil push rod can move up and down, driving the sealing plate to move up and down to push the lubricating oil into the oil pipe, thereby lubricating the ball between the outer ring and the inner ring.

[0043] Since the frequency of the abnormal sound signal received on the earpiece is relatively fast, the vibration frequency is also relatively fast when it is converted into a mechanical vibration signal. The oil push rod moves up and down at a relatively fast speed, and the sealing plate moves up and down at a relatively fast speed. Each time the sealing plate moves up, the oil is pushed to the third through hole. Since the sealing plate descends too fast, the lubricating oil cannot completely flow into the oil pipe from the third through hole, and a large part of the lubricating oil still falls back into the oil storage chamber, and the same is true for the next operation. This prevents the lubricating oil from flowing out of the oil pipe in large quantities at one time, resulting in the oil pipe being unable to continuously discharge oil.

[0044] When the oil push rod moves up and down, it will produce different moving heights due to different abnormal sound volumes, which will cause different amounts of lubricating oil pushed out by the oil pipes at different positions. When the outer ring rotates to the left or right, the position with more oil output is not necessarily the position where the abnormal sound is serious as detected by the earpiece. Therefore, in the process of the oil push rod pushing the oil out, it is necessary to try to balance the oil output in the oil pipes at different positions so that the lubricating oil can flow evenly to each ball between the inner ring and the outer ring. When the sealing plate pushes the lubricating oil, the sealing plate quickly pushes the lubricating oil and the air in the oil storage cavity, and the lubricating oil enters the oil pipe. While part of the air is pushed out of the oil pipe, part of it is pushed into the connecting pipe. The air pressure generated by the sealing plate with a higher moving height pushing the air in the oil storage cavity is also higher, which can pass the air through the oil pipe into the oil storage cavity where the sealing plate with a lower moving height is located, and further squeeze the lubricating oil in the oil storage body with a lower moving height of the sealing plate, so that the oil storage body with less oil output can be re-oiled, so that the lubricating oil can flow evenly to each ball between the inner ring and the outer ring.

[0065] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0066] The embodiment of the present application discloses a sound monitoring system for a reclaimer rotary mechanism. Example

[0067] Reference Figure 1 , Figure 2 and Figure 3 , including a rotating part, a base 150 and a sound monitoring system for a reclaimer rotary mechanism, including an outer ring 10, an inner ring 20, a receiver 30, a rolling body 40, an oil groove 50, a guide rod 60, a floating plate 70, a blocking block 80, an oil pipeline 90, an oil storage body 100, an oil push rod 110, a sealing plate 120, a connecting pipe 130 and a sealing cover 140. The outer ring 10 is connected to the rotating part, the inner ring 20 is fixedly installed on the base 150, the outer ring 10 and the inner ring 20 are connected through the rolling body 40, and a plurality of receivers 30 are evenly distributed around the inner side of the inner ring 20, and the receivers 30 can record sounds.

[0068] The rolling body 40 can be a ball 41. When the earpiece 30 detects an abnormal sound, lubricating oil is introduced into the rotating mechanism and the rotating mechanism continues to run for a period of time. The earpiece 30 continues to monitor the rotating mechanism. If the sound does not change much and continues, it means that the rotating mechanism is damaged, has a large displacement or is improperly installed. It is necessary to shut down the material reclaimer and disassemble the rotating mechanism for inspection and repair; if the sound stops, it means that the rotating mechanism is insufficiently lubricated; if the sound becomes smaller, it means that contaminants have entered the rotating mechanism, and the lubricating oil plays a certain buffering role in the rotating mechanism to reduce the sound to a certain extent.

[0069] At this time, continue to introduce lubricating oil to discharge the lubricating oil mixed with pollutants out of the rotating mechanism. If the noise in the rotating mechanism stops, it means that the pollutants have been discharged from the rotating mechanism. If the noise in the rotating mechanism cannot stop after two oil discharges, it means that the pollutants in the rotating mechanism are stuck tightly, and it is necessary to shut down the reclaimer and disassemble the rotating mechanism for repair.

[0070] The damage of the slewing bearing will not be known until the slewing bearing is severely damaged and stops working and cannot rotate. The problem that the slewing bearing is severely damaged and cannot be repaired and the slewing bearing needs to be replaced and the bucket wheel stacker reclaimer needs to be completely disassembled and replaced is solved, which is troublesome and wastes manpower and material resources.

[0071] Reference Figure 2 and Figure 4 A fixing bracket 151 is provided on the base 150, the inner ring 20 is fixed on the fixing bracket 151, the inner ring 20 is connected to the outer ring 10 through the rolling body 40, the outer ring 10 can rotate relative to the inner ring 20, the oil groove 50 opens upward, the oil groove 50 is fixedly connected to the fixing bracket 151 and sleeved on the fixing bracket 151, the outer ring 10 is accommodated in the oil groove 50, the oil groove 50 is provided with a second through hole 51 at the bottom away from the outer ring 10, the guide rod 60 is located on one side of the second through hole 51, the guide rod 60 is fixed on the oil groove 50, the floating plate 70 is provided with a seventh through hole 71, the floating plate 70 is slidably connected to the guide rod 60 through the seventh through hole 71, the blocking block 80 is located below the floating plate 70 and above the second through hole 51, the blocking block 80 is fixedly connected to the floating plate 70, and the blocking block 80 can block the second through hole 51.

[0072] The inner ring 20 is fixedly connected to the fixed bracket 151 , the oil groove 50 is fixedly connected to the fixed bracket 151 , and the outer ring 10 can be relatively fixed with the inner ring 20 in a horizontal position under the action of the balls 41 and can rotate relative to the inner ring 20 .

[0073] When the oil level in the oil groove 50 is high, under the guidance of the guide rod 60, the floating plate 70 floats on the oil surface and rises upward, and the blocking block 80 rises upward under the drive of the floating plate 70, and the blocking block 80 is separated from the second through hole 51, and the lubricating oil in the oil groove 50 can be discharged from the oil groove 50. As the lubricating oil in the oil groove 50 is discharged, under the guidance of the guide rod 60, the floating plate 70 moves downward following the oil surface, and the blocking block 80 connected to the floating plate 70 also moves downward at the same time and is plugged into the second through hole 51. At this time, the lubricating oil in the oil groove 50 is no longer discharged.

[0074] Reference Figure 2 and Figure 3The oil delivery pipe 90 is located above the inner ring 20, and the oil delivery pipe 90 is fixedly connected to the inner ring 20. The oil storage body 100 is located above the middle cavity of the inner ring 20. An oil storage cavity 101 is provided in the oil storage body 100, and a third through hole 102 is provided on the side of the oil storage body 100. The third through hole 102 is connected to the oil storage cavity 101, and the oil delivery pipe 90 is connected to the third through hole 102. A branch pipe 91 is also provided on one side of the oil delivery pipe 90, and the oil outlet side of the branch pipe 91 is close to the ball 41.

[0075] The oil delivery pipe 90 is a hard pipe that can support the oil storage body 100. A plugging object is provided below the connection between the main pipe of the oil delivery pipe 90 and the branch pipe 91 to prevent the lubricating oil from entering the bottom of the main pipe, so that the lubricating oil can flow from the oil storage chamber 101 into the main pipe of the oil delivery pipe 90, and then flow directly into the branch pipe 91 from the upper part of the main pipe, and then flow from the branch pipe 91 to the ball 41, and then flow to the oil groove 50, so that the outer ring 10, the ball 41 and the inner ring 20 can be immersed in the lubricating oil.

[0076] Reference Figure 2 and Figure 3 A support plate 21 is provided on the inner side of the inner ring 20, the earpiece 30 is located on the inner side of the inner ring 20, the earpiece 30 is installed on the support plate 21, the oil pushing rod 110 is located above the earpiece 30, the oil pushing rod 110 is electrically connected to the earpiece 30, the oil storage body 100 is located above the oil pushing rod 110, a first through hole 103 is opened below the oil storage body 100, the first through hole 103 is connected to the oil storage cavity 101, the oil pushing rod 110 passes through the first through hole 103 and is slidably connected to the first through hole 103, the sealing plate 120 is located in the oil storage cavity 101, the sealing plate 120 is fixedly connected to the oil pushing rod 110, and the sealing plate 120 is slidably connected to the oil storage body 100.

[0077] The earpiece 30 is fixed on the support plate 21 inside the inner ring 20. The earpiece 30 can receive abnormal noise generated on the slewing bearing. The sound signal on the earpiece 30 is converted into a mechanical vibration signal and transmitted to the oil push rod 110. The oil push rod 110 can move up and down. Since the oil storage body 100 is fixed on the inner ring 20 through the oil pipe 90, the oil storage body 100 supports and limits the sealing plate 120. At the same time, the oil storage body 100 limits the oil push rod 110 fixedly connected to the sealing plate 120.

[0078] The oil push rod 110 moves up and down, driving the sealing plate 120 to move up and down in the oil storage body 100 . The sealing plate 120 pushes the lubricating oil to flow toward the oil delivery pipe 90 , and the lubricating oil enters the ball 41 between the inner ring 20 and the outer ring 10 through the oil delivery pipe 90 .

[0079] Due to the different locations of the abnormality, the volume of the abnormal sound received by the earpiece 30 at different locations is also different. The earpiece 30 receives abnormal sounds of different volumes, and the size of the mechanical vibration signal converted is also different: the abnormal sound received by the earpiece 30 is loud, and the mechanical vibration signal converted is also loud, and the oil push rod 110 moves up and down at a higher height; conversely, the oil push rod 110 moves up and down at a lower height. The higher the moving height, the more lubricating oil is pushed to the oil delivery pipe 90, and the smaller the moving height, the less lubricating oil is pushed to the oil delivery pipe 90.

[0080] Since the frequency of the abnormal sound signal received on the earpiece 30 is relatively fast, the vibration frequency is also relatively fast when converted into a mechanical vibration signal, the oil push rod 110 moves up and down relatively fast, and the sealing plate 120 moves up and down relatively fast. Each time the sealing plate 120 moves up, the oil is pushed to the third through hole 102. Since the sealing plate 120 descends too fast, the lubricating oil cannot completely flow into the oil pipe 90 from the third through hole 102, and a large part of the lubricating oil still falls back into the oil storage chamber 101. The same is true for the next operation, thereby preventing the lubricating oil from flowing out of the oil pipe 90 in large quantities at one time, resulting in the oil pipe 90 being unable to continuously discharge oil.

[0081] Reference Figure 2 and Figure 3 The oil storage body 100 is provided with a fourth through hole 104 and a fifth through hole 105 , and the fourth through hole 104 of each oil storage body 100 is connected with the fifth through hole 105 of the adjacent oil storage body 100 through a connecting pipe 130 .

[0082] The fourth through hole 104 and the fifth through hole 105 are both located above the oil reservoir 100, the fourth through hole 104 is located at the upper left of the oil reservoir 100, and the fifth through hole 105 is located at the upper right of the oil reservoir 100, the fifth through hole 105 at the upper right of each oil reservoir 100 is connected to the fourth through hole 104 of the oil reservoir 100 adjacent to the right side of the circumference through a connecting tube 130, and the fourth through hole 104 at the upper left is connected to the fifth through hole 105 of the oil reservoir 100 adjacent to the left side of the circumference through a connecting tube 130.

[0083] When the sealing plate 120 pushes the lubricating oil, the sealing plate 120 quickly pushes the lubricating oil and the air in the oil storage chamber 101, and the lubricating oil enters the oil pipe 90. While part of the air is pushed out of the oil pipe 90, part of the air is pushed into the connecting pipe 130. The air pressure generated by the sealing plate 120 with a higher moving height pushing the air in the oil storage chamber 101 is also higher, and the air can be passed through the oil pipe 90 into the oil storage chamber 101 where the sealing plate 120 with a lower moving height is located, and the lubricating oil in the oil storage body 100 with a lower moving height of the sealing plate 120 is further squeezed, so that the oil storage body 100 with less oil output can output more oil.

[0084] As the oil push rod 110 moves up and down, it will produce different moving heights due to the different volumes of abnormal noises, which will cause different amounts of lubricating oil to be pushed out by the oil pipes 90 at different positions. The outer ring 10 may be rotating to the left or right, and the position with a large amount of oil output is not necessarily the position where the abnormal noise is severe as detected by the earpiece 30. Therefore, in the process of the oil push rod 110 pushing the oil out, it is necessary to try to balance the oil output in the oil pipes 90 at different positions so that the lubricating oil can flow evenly to each ball 41 between the inner ring 20 and the outer ring 10.

[0085] Reference Figure 3 The oil reservoir 100 is provided with a sixth through hole 106, and the sealing cover 140 can block the sixth through hole 106. When the lubricating oil in the oil reservoir 100 is consumed, the sealing cover 140 is opened, and oil is poured into the oil reservoir 100 through the sixth through hole 106, and the sixth through hole 106 is blocked with the sealing cover 140 after the oil is poured.

[0086] The implementation principle of the sound monitoring system of the rotating mechanism of the material grabber in this embodiment is: when the earpiece 30 detects an abnormal sound, the sound signal on the earpiece 30 is converted into a mechanical vibration signal and transmitted to the oil push rod 110. The oil push rod 110 can move up and down, driving the sealing plate 120 to move up and down to push the lubricating oil into the oil pipe 90, thereby lubricating the ball 41 between the outer ring 10 and the inner ring 20.

[0087] Since the frequency of the abnormal sound signal received on the earpiece 30 is relatively fast, the vibration frequency is also relatively fast when it is converted into a mechanical vibration signal, the oil push rod 110 moves up and down relatively fast, and the sealing plate 120 moves up and down relatively fast. Each time the sealing plate 120 moves up, the oil is pushed to the third through hole 102. Since the sealing plate 120 descends too fast, the lubricating oil cannot completely flow into the oil pipe 90 from the third through hole 102, and a large part of the lubricating oil still falls back into the oil storage chamber 101, and the same is true for the next operation; thereby preventing the lubricating oil from flowing out of the oil pipe 90 in large quantities at one time, resulting in the oil pipe 90 being unable to continuously discharge oil.

[0088] As the oil push rod 110 moves up and down, it will produce different moving heights due to the different volumes of abnormal noises, which will cause different amounts of lubricating oil to be pushed out by the oil pipes 90 at different positions. The outer ring 10 may be rotating to the left or right, and the position with a large amount of oil output is not necessarily the position where the abnormal noise is severe as detected by the earpiece 30. Therefore, in the process of the oil push rod 110 pushing the oil out, it is necessary to try to balance the oil output in the oil pipes 90 at different positions so that the lubricating oil can flow evenly to each ball 41 between the inner ring 20 and the outer ring 10. When the sealing plate 120 pushes the lubricating oil, the sealing plate 120 quickly pushes the lubricating oil and the air in the oil storage chamber 101, and the lubricating oil enters the oil pipe 90. While part of the air is pushed out of the oil pipe 90, part of the air is pushed into the connecting pipe 130. The air pressure generated by the sealing plate 120 with a higher moving height pushing the air in the oil storage chamber 101 is also higher, and the air can be passed through the oil pipe 90 into the oil storage chamber 101 where the sealing plate 120 with a lower moving height is located, and the lubricating oil in the oil storage body 100 with a lower moving height of the sealing plate 120 is further squeezed, so that the oil storage body 100 with less oil output can output more oil, so that the lubricating oil can flow evenly to each ball 41 between the inner ring 20 and the outer ring 10.

[0089] When the handset 30 detects an abnormal sound, lubricating oil flows out of the oil pipe 90 and flows to the ball 41. The rotating mechanism continues to run for a period of time, and the handset 30 continues to monitor the rotating mechanism. If the sound does not change much and continues, it means that the lubricating oil continues to flow to the ball 41 and flushes the ball 41 but still has no effect, which means that the rotating mechanism is damaged, has a large displacement or is improperly installed, and it is necessary to stop the reclaimer and disassemble the rotating mechanism for inspection.

[0090] If the noise stops, it means that the rotary mechanism is not lubricated enough. After the lubricating oil is introduced into the ball 41, the rotary mechanism can work normally. At the same time, the noise stops and the oil in the oil pipe 90 stops flowing.

[0091] If the noise becomes smaller, it means that pollutants have entered the rotary mechanism. The lubricating oil plays a certain buffering role in the rotary mechanism, which reduces the noise to a certain extent. Since the noise has not stopped, the lubricating oil continues to flow into the oil pipe 90. When the lubricating oil reaches a certain amount, the block 80 in the oil groove 50 is separated from the second through hole 51, and the lubricating oil mixed with pollutants in the oil groove 50 is discharged from the rotary mechanism, and new lubricating oil continues to flow into the ball 41. If the noise in the rotary mechanism stops, it means that the pollutants have been discharged from the rotary mechanism and the oil pipe 90 stops flowing; if the noise in the rotary mechanism cannot stop after two oil discharges, it means that the pollutants in the rotary mechanism are stuck tightly, and it is necessary to shut down the reclaimer and disassemble the rotary mechanism for maintenance. Example

[0092] Reference Figure 1 and Figure 2 , an application process of a sound monitoring system for a reclaimer rotary mechanism, the difference between this embodiment and embodiment 1 is that,

[0093] S1: When the earpiece 30 detects an abnormal sound, lubricating oil is introduced into the rotary mechanism and the rotary mechanism continues to run for a period of time. The earpiece 30 continues to monitor the rotary mechanism. If the sound does not change much and continues, it means that the rotary mechanism is damaged, has a large displacement or is improperly installed. It is necessary to stop the reclaimer and disassemble the rotary mechanism for inspection;

[0094] S2: If the sound stops, it means that the rotary mechanism is not lubricated enough;

[0095] S3: If the noise becomes smaller, it means that pollutants have entered the rotary mechanism. The lubricating oil plays a certain buffering role in the rotary mechanism, which reduces the noise to a certain extent. At this time, continue to introduce lubricating oil to discharge the lubricating oil mixed with pollutants out of the rotary mechanism.

[0096] S4: If the noise in the rotary mechanism stops, it means that the pollutants have been discharged from the rotary mechanism; if the noise in the rotary mechanism cannot stop after two oil drains, it means that the pollutants in the rotary mechanism are stuck tightly, and it is necessary to stop the reclaimer and disassemble the rotary mechanism for inspection and maintenance.
